QUILTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 325,799, dated September 8, 1885.

Application filed May 8, 1895. (No model.) I

To all whom it may concern.-

Be it known that 1, JOHN B. HAGENB'L'IGHLE, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Quilting-Machines, of which the followingis a specification.

My improvement relates particularly to quilting machines which are designed for making lines of stitching obliquely across a fabric from side to side. The improvement is designed to enable such work to be donecontinuously-th'at is, without necessarily stopping the machines from time to time.

In my machine I employ a series of needles, which have a lateral traverse continuously, as Well as'an ordinary reciprocating movement, while the fabric is fed continuously forward.

I will describe a machine embodying my improvement, and then point out the various features of the improvement in claims.

The accompanying drawings illustrate a machine embodying my improvement. Figure l is a front view. Fig. 2 is an end view. Fig. 3 is a transverse section taken at the plane of the line 1 1, Fig. 1. Fig. 4 is a transversesection taken at the plane of the line 2 2, Fig. 1.

Fig. 5 is a back view of a portion of the needle-bar and its appurtenances. Fig. 6 is a plan or top view of the same. Figs. 7 and 8 are details of certain parts acting in conjunction with the needle bar. tudinal view of a portion of one of the shuttle- Fig. 10.is an end view of a portion of the shuttle-race. Figs. 11, 12, and 13 are details of the needlebar. Fig. 14 is a front view of a portion of the take-up mechanism. Fig. 15 is a plan of the feeding device. Fig. 16 is a detail view of a device for cutting threads, and Fig. 17 is a view showing the kind of work' done in the machine.

Similar letters of reference designate corresponding parts in all the figures.

. I will first describe the needle-bar and the device for actuating the needles.

A designates the need1e-bar. It is formed of anapproximately Lshaped piece of metal, as shown more clearly in Fig. 3, with flanges extending at the top and bottom from both sides. By this'means the needle-bar is provided with grooves a. a, extending longitudinally throughout the length of the bar. An

Fig. 9 is a longiother ends are provided with collars a, which surround and are loosely connected to a bar, a above the needle-bar A, and extending parallel therewith. Vertical rods a which are secured at their lower ends to the needle-bar A, pass upwardly through apertures in thebar a and are secured in said apertures by By this means the means of set-screws a. needle-bar may be adjusted vertically with relation to the bar a rods 01 extend through suitable apertures in the upper portion of a cross-piece or stretcher, A forming part of the main frame of the machine. The apertures in said portion A,- through which the rods a pass, constitute guides therefor, and tend to steady the needlebar in its up-and-down movements The needle-bar is further steadied by means of guides or housings a extending downwardly from the cross-piece or stretcher A of the frame.

B designates needle-holders, to the lower ends of which needles [2 may be secured in the usual or any suitable manner. Each of these needle-holders is separate from the others, and has rigidly secured to it near its upl per end a head, b; This head may, however, be cast with the needle-ho1der,.if desirable.

When the needles are in operation,or, in other those needle-holders whose headsare engaged with the groove a. Each of the needle-holders extends downwardly through apertures The links a and the forming slideways in an endless chain consisting, essentially, of two sets of links, .0, joined together by connecting-rods b this chain are shown in Figs. 11, 12, and 13. of the drawings.

formed integral with it a projecting portion,

Each of the links C has Details of A I), here shown as rectangular, through which extends the aperture or slideway before referred to. The rods biextend through apertures in portions b in the links C. The ends of the rods may be riveted up like hingepins, to'prevent their dropping out of the chain. The needleholders B may move freely up and down in the slideways in the links 0 of the chain. The links, therefore, act as guides for the needle-holders in their reei procati ng move ments; but they have an additional use, which I will proceed to describe.

It must be borne in mind that the needles have a lateral traverse as well as an up-and- J journaled in suitable hearings in the frame.

I shall omit a description of the portion D of the drum D D for the present. The endless chain also passes around this drum D. The chain is supported vertically by the impingernent of its upper row of links, 0, upon the top of the drum D and on the top of the portion D of the drum D D Each of these drums is provided with indentations, with which the rods 1) of the chain 0 b engage. It will be seen, therefore, that as the drum- D is rotated it will impart motion to the chain 0 b which in turn will rotate the drum D D. Spools holding thread are upon and adapted to turn freely 'about' pins or spindles b on brackets or plates 2), which are secured, one upon the front of each of the projections 1) upon the links 0 of the chain, by screws or otherwise. In order to accommodate spools of large size, I have found it expedient to con struct these plates b of varying lengths, as by so doing I am enabled to arrange the spools in tiers or rows, one above the other. In the outer end of the pins b are fitted pins I). These pins I) extend transversely through the pins 6, and are maintained in positionwi thin the apertures of the pins I)", that receive them, by friction. Each thread passes from thespool first through a hole near the upper end of the pin b *,which is adjacent to the spool, thence through a clip projecting from such pin 1), thence through a notch, b, in the end of the pin 1), thence through a hole near the lower end of such pin 1), thence through a loop or eye, b on the front face of one of the projecting portions of alink, O, in the lower portion of the chain 0 b thence upwardly and through an eye, 6", near the outer extremity of a lever, b, which is pivotally connected to one of the plates 5 This lever,as shown, is somewhat ogee-shaped, and is provided with a longitudinal slot. An arm, b, which is rigidly connected to one of the needle-holders B,and extends outwardly at raisin of the lever 12, and eonse ucntl Y the a .l

slack of the thread is taken up.

Although I have shown only a few of the needle-holders B and their appurtenances, it is intended in practice that the same shall form an unbroken series about the endless chain 0 b The endless chain 0 b in its passage around the drums D D D carries with it the needle-holders B and their appurtenances, and it will therefore be seen that certain of said needle-holders are constantly and successively being moved into engagement with the needle-bar A at one end of the latter, and out of engagement with the same at the other end. When notin engagement with the needle bar, the needle-holders and their appurtenances are supported and slide upon a bar,'G,which follows the contour of the endless chain inside the same or nearer the crosspiece or stretcher A of the frame. The endless chain 0 b is guidedin its movements both at the front and rear of the machine by guides consisting of longitudinal grooves formed in the under and upper side of rails or ribs at, extending from the cross'piece or stretcher A of the frame, into which grooves project pins or l ngs d on the links of the chain. Thebar G is supported by braces (Z, extending outwardly from the cross-piece or stretcher A of the frame. The. ends of the bar G approach the vertical plane of the needlebar A, at either end thereof, to within a distance approximating the width of one of the projecting portions I) upon the links 0 ofthe endless chain 0 b so that the needle-holders may be readily moved into and out of the needle-bar.

In order to facilitate the engagement and disengagement of the needle-holders with the needlebar, I employ the following device, (more clearly illustrated in Figs. 5, 6, 7, and 8:)

H designates a slider-bar adapted to slide to and fro in the groove a, formed in the back of the needle-bar A. Guide-screws e are fast in the needle-bar, and extend through longitudinal slots 6 in the slider-bar, with their heads outside the slider-bar. By this means the slider-bar is retained in its position on the needle-bar, and is yet capable of the toandfro motion referred to. This slider-bar has at one end a head, 6 at the other end a head, 6*. These heads are approximately rectangular, and extend forward from the sliderbar or toward the front of the machine so far that they are in contact with the heads b on the needle-holders B in front of them. Upon their front faces they are provided with IZC grooves which are adapted to receive the lugs or projections a upon the needle-holders B. The groove upon the head 6 is arranged in such position that when a head,b,on a needleand-down motion which those needleholders have that are in engagement with the needlebar. As the needle-bar A is being moved up and down rapidly, it isnecessary that the engagement of the head 6 with the needle-holder which has just left the rail G should be erfected very quickly, and this is done by the reciprocating motion of the slider-bar. This reciprocating motion is for thepurpose of guiding the needle-holder with which the head 6 is in engagement across the space intervening between the end of the bar G and the needle-bar A until the needle-holder is safely in engagement with the needlebar. When it has so guided a needle-holder into the needle-bar, it is shot back with great rapidity into engagement with the. needleholder which has been moved along by the endless chain into the position just occupied by theneedle-holder which has been placed in engagement with the needlebar. I prefer to effect this engagement with the needle holder when the needle-bar is at the top of its upstroke, as a slight dwell occurs in the motion of the needle-bar at that point.

The rapid engagement of the head e on the slider-bar with the oncoming needle-holder is effected in the following manner:

I designates a rod arranged at the rear of the slider-bar H and extending parallel there with. As shown, it extends through collars 6 forming part of the slider-bar, and is secured in said collars by set-screws or other wise. It therefore has a rigid connection with the slider-bar, and motion transmitted to it will be transmitted to the slider-bar. The rod 1 receives motion in one dircction by means of teeth upon an upwardly projecting portion, D of the drum D, which teeth during the rotation of saiddrum al ternately press against the downwardly-extending arm 6 on the rod I, thereby causing the rod tomove' in the direction of thearrow shown in Fig. 6 until the tooth with which the arm 6 is in engagement has moved so far that the said arm will slip past it. When said tooth has moved past the arm, the rod I is rapidly shot forward until thearm 0 comes in contact with the next oncoming tooth upon the drum. The rod is shot forward by the action of a spring, 0, coiled about the rod I, and bearing at one end against one of the col lars e, and at the other againsta collar, 6 which forms a portion of the needle bar. This connected to them shuttle races f.

collar e and another, also connected to the needlebar A,'serve to guide the rod I in its movements. I

It will be observedthat the teeth upon the portion D of the drum are shouldered, or, in other words, the teeth are of less projection in the direction of the diameter of the drum near the free end of the portion D of the drum than at the other portions thereof. The shoulders upon all the teeth are in the same plane. By so shouldering the teeth I am enabled to regulate as desired the exact point in the upward movement of the'arm e atwhich the same shall slip past the tooth with which it is in engagement, forit is obvious that the shorter the tooth in the direction of the diameter of the drum the sooner will it be moved into a position where the arm 6 will slip past it, and by suitably arranging the point at which the tooth is shortened I may provide for the slip of the arm 6 at any desiredmoment, When the bar I is shot forward by the spring, the head 6 on said bar receives the needleholder which has just moved off from the needlebar, and as the bar I is moved in the reverse direction it deposits said needle-holder upon the adjacent end of the bar G. shown a downwardly-extending guide, e, for the rod I, secured to or formed with the bar of. The rod I extends through an aperture in said guide.-

I will now describe the shuttle mechanism.

Each of the shuttles is supported upon an endless chain consisting, essentially, of two sets of links, J, joined together by connectingrods' f. This endlesschain J f constitutes a number of traveling shuttle'races, to which motionis imparted by a rotating drum, K, 10-

, cated near one side 01 the machine and beneath I have roo the drum' D. The chain also passes around another drum,'K, located near the opposite side of the machine beneath the drum D D and fast upon a shaft, K", journaled in suitable bearings in the frame. The drums K K are indented to receive the rods f of the chain. These drums are arranged bcneath'the clothplate or apron L of the machine, with their axes in a direction at right angles to the axes of the drums D D D The shuttle-races are therefore at right angles to the needle-holders B. The links Jof-thechain which are oppo site each other have extending between and (Shown more clearly in Figs. 9 and 10.) The shuttleraces aresecurcd to the links by lugs or projections f*, (more clearly shown in Fig. 9,) through suitable apertures in which pass the rods f. Said shuttle-races thereby form a portion of the links of the chain. Shuttlesf are adapted to be reciprocated in the shuttleraces. Those shuttleraces, which are upper.-

most, or, in other words,those holding shuttles which are in operation, are supported and guided as they move along by bars f extending between the drums K K, and which are I bolted or otherwise secured to a portion, A,-

of the frame of the machine. Each of the shuttle-races is provided upon its top with a throat-plate, f, having in it a hole,f through which the needle may pass. Plates 1) upon the shuttle-races near the throat-plate f prevent the shuttles from dropping out of the races when not in operation.

The shuttles are reciprocated in the shuttleraces by means of shuttle-drivers f. I prefer to construct these shuttle-drivers of metal rods having one of their ends curved in such manner as to extend over the nose of the shuttle, and being provided with pins or projections extending behind the shuttle. Ribs or projectionsf entering longitudinal groovesf in the surfaces of the adjacent shuttle-races, act to prevent the shuttledrivers from dropping out of the sh uttle-raees when not in operation. The ends of the shuttle-drivers which are not in engagement with the shuttles extend beyond the endless chain J f toward the rear of the machine, and are here shown as bent at approximate right angles to the length of the drivers. Such bent ends are adapted to enter a groove in a bar, M, and slide along upon a bar, M. The bar M has a motion alternately toward the front and back of the machine. In Fig. 3 the bar M is shown in its most forward position. It actuates the shuttledrivers which are in engagement therewith. It is supported on rods U, that slide longitudinally in bearings U erected upon the portion A ofthe frame of the machine. Motion is imparted to these rods, and consequently to'the bar M, by means of crank-wrists connected to a main driving-shaft, N, and pit man-rods U, extending from said crank-wrists to, collars a, secured to the rods U The bar M acts as a guide for the shuttledrivers which are not in operation. It has its ends bent upward and toward each other, and it occupies the vertical planev which the bar M occupies when in its most rearward position.

The endless chain Jf moves in unison with the-endless chain 0 b and the arrangement of the shuttle-races upon the chain Jf is such that when one of the needle-holders B is moved into engagement with the needle-bar A one of the shuttle-races will be at the same time moved into such position that the shuttle being carried therein will co operate wit-h said needle-holder and its needle to form stitches.

In order to move the shuttledrivers into engagement with the rapidlyreciprocating bar M, I employ mechanism, arranged upon the bar M, which is in all respects similar to that previously described for moving the neele-holders into engagement with the needle bar, which mechanism is clearly illustrated in Figs. 5, 6, 7, and 8. The drum K will also be provided with an outwardly -extending toothed portion in all respects similar to the portion D shown and described for the drum 1), acting in conjunction with the mechanism just referred to. For the reason that theseparts will be identical in construction, I have not deemed it expedient to duplicate the illustrations.

It must be understood that the mechanism for moving the shuttle-drivers into engagement with the bar M moves them continuously and successively into engagement therewith at one end and out of engagement therewith at the other end.

I prefer to employ two presser barsone,E, adapted to press upon the goods being sewed in front of the needles, and the other, E, behind them. These presser-bars extend across the machine in a direction transverse to the direction of the feed of the goods. The barE has upwardly and somewhat outwardly extending arms, 0, rigidly secured thereto, as shown more clearly in Fig. 3. These arms are provided near their outer ends with sockets, in which are secured, by screw-threads or otherwise, the lower ends of vertically-extending rods E". Above said sockets the rods E pass loosely through apertures in a bar, 0 extending between the side frames of the machine and forming a portion of the frame. Above the bar 0 said rods also pass loosely through apertures in projecting portions 0 ofthe crosspiece or stretcher A of the frame. Above the said cross-piece or stretcher A" of the frame said rods are rigidly connected near their upper ends to yokes 0, extending about the rock shaft A. Rods 0 extending between said yokes, connect them together and tend to make their action uniform. The bar 0 and the portions 0 of the cross-piece or stretcher A, through which the rods E pass, act as guides for said rods. The presser: bar E, which is behind the needles, has rigidly secured toit arms c ,which are somewhat shorter than the arms 0 upon the bars E. The arms 0 are provided near one of their ends with sockets, in which are secured vertically-extending rods E similar to the rods E The rods E are guided in guides c and 0 upon the cross-piece or stretcher A" of the frame. Near their upper ends these rods E are rigidly secured in sockets of the yokes 0 The presserbars E E are intended to move in unison. The motion which lifts them up from the goods is imparted to them by means of cams 0 upon the rock-shaft A, which, at each rocking of said shaft, elevate the yokes c by coming in contact with lugs c on said yokes. After the cams have acted on the yokes, the speedy return of the presser-bars to the goods being sewed is facilitated by means of springs 0, coiled about the rods E and E and bearing, in the case of the rod E, at one of their ends against the arms 0, and at the other against the bar 0 and in the case of the rods E hearing at one of their ends against the guide 0 and at the other against the arms a.

The main driving-shaft N is located to the front of the machine, and may have motion transmitted to it by a belt-pulley, g, in the usual or any suitable manner. This shaft is journaled in suitable bearings, g, in the side frames of themachine, and also in bearings 9, located upon the bed of the machine at suitable distances between the side frames. Collars 9 upon the drivingshaft inward of the nected together by crank-pins.

intermediate bearings, g, prevent lateral movement of said shaft. I prefer to make this shaft in sections, of which I have shown four, and unite said sections by means of cranks g consisting of disks rigidly con- The form of one of these disks with connecting crank-pin is clearly shown in Fig. 1. I' prefer to cast the said disks and crank-pin in one solidpiece and secure the ends of the adjacent sections of the shaft to the disks by feathers or splines. The rock-shaft A and the mechanism for r0- tating the drums D and K are operated from the crank 9 O designates a connecting-rod loosely connected near one end to the crank-pin of the crank g and near the other end to an arm, h, whicharm is rigidly secured to one end of the rock-shaft A. By this means a rocking motion is imparted to said rock-shaft, and the needle-bar and presser-bars are actuated.

A connecting-rod, O, actuated by a crank, 9 upon the driving-shaft and connected to an arm, h, fast near one end to the rock-shaft A, is arranged at the opposite side of the machine to the rod 0, and assists in operating said rock-shaft. This rod 0 and its accompanying mechanism may, however,be omitted,

if desired.

P designates a con'nectingrod having a loose connection near one end with the crankpin of the crank g and an adjustable connec tion. near the other end with a lever, i, fulcrumed upon a bracket, '6, upon the frame. By means of this adjustable connection I am enabled to secure the lever i in different positions in its length upon the rod P. The other end of the lever 13 is pivotally connected to onearm of a bell-crank lever, i fulcrumed upon a bracket, 2', upon the frame.- The other arm of the bell-crank lever i is provided with a'beveled toothed sector, i. ported and adapted to oscillate upon a stud, i is provided at one end with atoothed sector, i, that engages with the toothed sector i and at the other end with a toothed sector, 6", which engages with a gear-wheel, t. The gear-whcel i is loose upon an upright shaft, R, journaled in suitable bearings upon the frame. A lever, i, is keyed to a hub upon the under side of the gear-wheel i and moves withsaid gear-wheel. The outer end of the lever carries a pawl adapted to engage with a ratchet-wheel, i, rigidly secured to the shaft B. As the crank g is rotated, the connecting-rod P is alternately raised and lowered, imparting arocking motion to the levers iand i This motion is transmitted to the sector-lever 2', through which it is transmitted to the gear-wheel z' and the lever i. The movement of the lever i in one direction operates to move its pawl backward one tooth upon the ratchet-wheel ifl and its movement in the other direction rotates the ratchetwheel a distance approximately the length .of one ofthe teeth on the ratchet-wheel. An

A lever, i, sup- 7 intermittent rotary motion is thereby imparted to the shaft R. The shaft It bears at its upper end a bevel gear-wheel, S, which gears into another bevel gear-wheel, S,-fast upon one end of a shaft, j, extending at right angles to the axis of the shaft R and j ournaled in suitable bearings upon the frame. The shaft j bears a worm, j", which engages with a worm-wheel, S keyed to the upwardlyextending end of the vertical shaft T. It will be advantageous to make this worm-wheelS in two sections-one affixed to the shaft T, and the other loosely fitted to the shaft T and connected to its fellow so as to be capable of circumferential adjustment with relation to its fellow. This provides for a nice adjustment of the mechanism which I have just. described, so that they may work accurately. The shaft R also bears another worm, j, near its lower end, which engages with a wormwheel, S", which is keyed to a horizontal shaft, T, journaled in suitable bearings upon the frame. The worm-wheel S is made in two sections, similar to the worm-wheel S The shaft T has keyed to it near its other end the drum K, by which the chain J) is moved along. The bevel gearwheels S S are, as shown, of the samesize, the worm-wheels S and S are, as shown, of the same size,and the worms 9' j are, as shown, of the same size. It will accordingly be seen that the intermittent motion imparted to the shaft R is transmitted to the shafts T and T, and that the endless chains C b and J f move intermittently in unison.

By the foregoing arrangement of parts a very positive and. uniform motion is imparted to the needles and shuttle-races, which causes the needles-and shuttles to act together to a nicety. The drums D D, D K K are of the same diameter and are the same distances apart,and

- the endless chains 0 b and J f are of the same length.

The goods being sewed are drawn along beneath the needles by means of feed-rollers W W. The roller W is shown as supported in immovable bearings, and the roller WV is supported in bearings arranged in housings n, adapted to slide toward and from the roller W,and impelled toward the roller V by means of springs 12, the pressure of which is regulated by means of screws a". An intermittent rotary motion is imparted to the roller W. The roller W keeps the goods-in contact with the roller W, and may rotate as the goods move beneath it.

. V is an arm hung on the main driving-shaft, and having an opening elongated in the direction of the length of said arm where it embraces said shaft. l

V is a cam affixed to the driving shaft and operating upon bowls or anti-friction rollers Z Z, with which the arm V is provided. Iprefer to bifurcate the arm V at the portion where it is hung on the drivingshaft, so that it will embrace the cam V. The roller or bowl Z is journaled in a loose collar, Z surrounding the forward extremity of the arm V. The outer extremity of the arm V, upon which the collar Z is fitted, is longitudinally slotted. A bar, Z passes through this slot and bears against the collar Z A coil-spring, 1*, bears at one end against the bar l ,and at the other against the outer end of the slot in the arm V in which it fits. This allows of a yielding motion of the roller Z". Near one end the arm V is connected to a lever, V, by means of a set-screw passing through a longitudinal slot in said le ver. The lever V actuates arms m at one of their ends, surrounding a rim on the periphery of a clutch-wheel, V which is rigid upon the end of the feed-roller W, and at the other of their ends bearing against rollers or bowls m upon the lever V A coil-spri1ig,m, is connected to the clutch-piece'm near the end thereof, which surrounds the rim on the clutchwheel V and at the other to one arm of the lever V; and a coil-spring, m, is connected to the clutch-piecem near the end thereof,which surrounds the rim on the clutch-wheel Viand at the other end to the other arm ofthe lever V As the lever V is moved to and fro by the action of the cam V, it operates to rock the lever V, which latter, *by means of the coil-springs m m and the bowls m causes the clutch-pieces m 'm to alternately clutch and release the rim on the clutch-wheel V and rotate the same. By this means intermittent rotary motion is imparted to the feedroller W. I

In this machine it is necessary to cut both the needle and shuttle threads after the needles have ceased to operate upon the goods. I provide for cutting the threads automatically by means of a cutter, Y. (Shown in Fig. 16, where the goods are designated Z.) This cutten as shown, consists of aplate from which extend arms bentv from each other in a horizontal plane, so as to form a V-shaped opening between them, and also bent from each other into different vertical planes. The edges of the arms adjacent to the V-shaped opening are sharpened. The cutter is secured to the work-plate of the machine, and extends at such an angle to the direction of transverse movement of'the needles and shuttles and to the feed of the goods that the threads from the needles and shuttleswill be successively drawn between the V-shaped'arms of the cutter and cut by the sharpened edges thereof. That arm of the cutter which is lowermost may be sunk into the bed-plate so as to be flush with the surface thereof, if desirable. The cutter will preferably be made of steel.

I have shown this machine so organized that the needles will move from left to right over the work being sewed; but obviously it may be so constructed that the needles and their complementary parts will travel in the other directionendthe sewing be done from right toleft.
