T0 @ZZ whom it may con/cern..-

Be it known that we, LOUIS SOHULTZ and THEODORE A. W'EBER, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Sewing-lvlachines, of which the following is a specification.

This improvement relates particularly to machines in which a gang or a number of needles are employed.

The principal object of this improvement is to provide a machine by which diagonal quilting may be performed. In such quilting a number of parallel lines are stitched obliquely across the goods from side to side. It is not desired to produce a machine which will be capable of doing this character of work only, but of producing a machine which may do this work whether or not it is also capable of doing other work.

The improvement consists in the combination of a reciprocating gang or series of needles and a work bed or support arranged adjacent thereto and made of circular form transversely, the work havingalongitudinal movement axially of the bed. Preferably the bed will be made in the form of a cylinderg'butit need not, however, be made in the form of a complete cylinder. The work bed or support will preferably be so arranged as to extend axially in the direction of the length of the gang or series of needles.

The improvement also consists in various other features, which will be hereinafter described and claimed.

In the accompanying drawings, Figure l is a top view of a machine embodying our improvement, certain parts, however, being shown in sections. Fig. 2 is an end view ofthe same. Fig. 3 is a back View thereof with certain parts represented in sections. Fig. l is a transverse vertical section ofthe machine; but in this view we have omitted to represent certain parts which would be apparent, but which, it' represented, would tend to confuse the parts sought to be particularly represented in this view. Fig. 5 is a front View of certain parts of the machine. Fig. 6 is a horizontal section taken at the plane-of the dotted line x m, Fig. 4, and representing certain parts of the machine. Fig. 7 is a perspective present example of our improvement.

bar is guided along rods a, which are fixed to `the frame-work B of the machine.

View illustrating the principal parts of a mechanism which effects or contributes to effect the feeding of the goods to be quilted in the` direction of the axis of the work bed or support. Fig. 8 is a front view in perspective, showing the principal parts of the machine, the same being partly in section, and certain parts being omitted which might otherwise tend to render the construction of the illustrated parts obscure.

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

A 'designates a gang or series of needles. As shown, these needles are all arranged in a single row, although this arrangement is not of the essence of our-improvement, and attached to a common needle-bar A. The needle-bar, with the needles fastened thereto, has

a reciproeation in a vertical plane in the Said The reciprocation of the needle-bar is eected by means of a rock-shaft A2, furnished with crank-arms a and links A3, which are pivotally connected to the said crank-arms at one end and to t-he needle-bar at the other.

The rock-shaft A2 is rocked or oscillated by means of a crank c, which is affixed to one end of the main shaft O of the machine, and a link c', extending from this crank to a crank-arm a3, which is affixed to one end of the said rock-shaft.

The main shaft O of the machine is journaled in an ordinary manner to the frame B of the machine and may be rotated by any suitable means-as, forinstance, a belt operating in conjunction with fast and loose pulleys arranged upon such shaft.

D designates awork bed or support having a curved surface. As shown, it is made in the form of a hollow cylinder, and is arranged directly beneath the needles A in such position that its axis will be parallel with the gang of needles and the needle-bar. This work may pass IOO ranged. YVe have not deelned it necessary to illustrate the shuttle-carriers or the shuttles which are to be used therewith, for there will not necessarily be anything novel about these parts. XVe have, however, shown an oscillating bar E, arranged within the work bed or support D, opposite the opening d thereof, such bar being suitable for eifecting the traverse of the slmttle-carriers with their shuttles.

The bar E is supported by arms E', that are mounted upon a rock-shaft E2. This rockshaft E2 extends through the cylindrical work bed or support and is journaled in bearings aflixed to the latter or any suitable partof the frame B of the machine.

The rock-shaft E2 is rocked or oscillated by means of the crank c, with which the main shaft C of the machine is provided. In order that the crank may perform this work, it is pivotally connected to one end of a link e, which at the other end is connected to one arm of a bell-crank or elbow lever e', fnlc'rumed to the frame B of the machine. The other arm of thelever e is pivotallyconnected to one end of a rod e2, which at the other end is pivotally connected to an arm e3, extending from a rock-shaft e4. The rock-shaft e4 has aixed to it a second arm e5, which is pivotally connected to one end of a rod e, which at the other end is pivotally connected to a crank-arm e7, that is affixed to the rock-shaft E2. By the mechanism just described the rock-shaft E2 and the bar E will be rocked or oscillaied at the proper times relatively to the reciprocations of the needle-bar.

Having now explained all that is necessary to explain in reference to the mechanism, the shuttle mechanism, and the shape of the work bed or support, saving only that i-t is not absolutely necessary that the latter should be made in the forln of a complete cylinder, we will turn our attention to the mechanism whereby the goods, work, or fabrics to be quilted are fed beneath the needles.

It will, we believe, conduce to a clear understanding of the feed mechanism to premise that it feeds the goods lengthwise of the work bed or support, or, in other words, in the direction of the axis of the latter, and that it also feeds the goods in a curved path around the work bed or support. The goods will be fed in these two directions simultaneously, and preferably with an intermittent action corresponding to the stitching done upon it. As the longitudinal and circumferential feeding of the goods occur simultaneously, the goods will receive a resultant feed spirally around the work bed or support. At or near the ends of the work bed or support there are fitted to it rotary supports F P2 for certain feeding mechanism. These rotary supports are arranged one at cach end of the work bed or support and rotate around the axial line of the latter and while the latter remains stationary. The rotary support F carries a takeup or feed roller or rollers and a guide for dircctin g the goods from the curved surface of thc work bed or support to the straight surface of such take-up or feed roller or rollers. The rotary support F2 carries a delivery roller or rollers and a guide serving to direct the goods to be quilted properly from the said delivery roller or rollers to the curved surface of the work bed or support.

Before giving a detail description of the feed and delivery rollers or their guides I will explain the means by which the rotary supports F F2 are driven. rlheyare provided at their outer ends with beveled gear-wheels f f2, which mesh or engage with beveled pinions fsf", affixed to shafts f5. These shafts f5 are journaled in bearings with which the frame-work 3 of the machine is furnished. They have also aiiixed to them beveled gearwheels fGfT, which mesh into beveled gearwheels f3 f, affixed to a shaft f 10. This shaft flois suitably journaled in the frame B of the machine and extends lengthwise of thc machine, or, in other words, in the same direction as the needle-bar and the work bed or support. Consequently the shafts f5 will ez;- tend transversely thereto and from it toward the work bed or support. The shaft fw is furnished with a worm-wheel f, with which engages a worm fifi, which, as here shown, is arranged upon an upright shaft f 13. This worm-shaft f 13 is journaled in the frame-work B of the machine and at the upper end has affixed to it atoothed wheel f1". Adjacent to the toothed wheel f ILLthere is loosely mounted upon the shaft f 13a pawl-lever fw. The pawllever has two arms and carries a two-armed pawl f 16, which is impelled against the toothed wheel f14 by means of a spring fm' The pawllever j"15 may be swung into either of two positions, so that either of its arms will extend across the path of a cam or tappetfls, and when adjusted into either of its extreme positions it will be held there except when moved aside by the said cam or tappet by means of a spring f1, which is fastened to said lever and also to a portion of the frame B of the machine. rlhe pawl carried by the lever may also be swung into either of two positions, so that either of its arms will operate upon the toothed wheel fl. This wheel has its teeth so formed as to be alike on both sides. It is so constructed and the pawl and pawl-lever are made in the manner described in order that the wormshaft f13 may be rotated in either direction, while the cam or tappet is made to rotate continuously in the same direction. Thus provision will be afforded by a very simple and easy adjustment of parts for driving the rotary supportsff2 in either direction without changing the driving of the whole machine. The cam or tappet fis is shown in the present example of our improvement as consisting of adisk affixed to an upright shaft G and provided at or near its pc ri phcry with an anti-friction roller or bowl.

As we stated at the outset in this specifica- `tion, thc principal object of our improvement IOO - borne in mind that these rotary supports carry the take-up or feed and the delivery rollers and thereby impart to the goods to be quilted the same rotation which they receive themselves.

The shaft G is provided at its upper end with the beveled wheel g, that engages with a beveled wheel c2, aiiixed to the main shaft C of the machine. Hence the shaftG is driven directly from the main shaft.

H H2 designate a pair of feed-rollers, and H3 designates a take-up roller. These rollers constitute holders for th e work. It may not be necessary to use the feed-rollers in addition to the take-up roller. These rollers H H2 H3 are carried by the rotary support F. They are journaled in brackets h h2, which are affixed to this rotary support. Adjacent to the rotary support F is acircular rack h3. This rack is immovable. It is secured by bolts or other means to a portion of the frame B of the machine. It is concentric with the rotary support F', and consequently with the work bed or support. The gear-wheel h4, mounted upon a stud h5, whichisaffixed to the bracket h of the rotary support F', engages with the circular rack h3 and travels around the latter when it is revolved by the rotation of the support F. As it revolves it rotates on its own axis. lt engages with a gear-wheel h, which is mounted on a stud or shaft h?, journaled in bearings provided upon the brackets 7a. The shaft k7 has also affixed to it a beveled gear-wheel hs. This beveled gear-wheel 9 engages with a beveled gear-wheel h which is affixed to one of the journals of the feedroller H2. The rotary motion which the gearwheel h4 acquires in revolving around the circular rack h2 will be transmitted to the gearwheel h, and by the latter transmitted through the beveled gear-wheels hs hg to the feed-roller H2. The feed-roller H need not be positively driven, but may rotate simply by the action of the goods passing between it and its feedroller H2; but we have shown these two feedrollers as driven positively through the agency of intermeshin g gear-wheels 71.1, affixed to corresponding journals.

The take-up roller H2 is shown as having its journals fitted into slots which extend lengthwise of the brackets h h2. Springs h are employed to pull this take-u p roller toward a bar H4, which is affixed to the brackets h h2. The take up roller will therefore be moved as near to the bar ,Hl as the goods wound upon it will permit, and 1t will recede from the bar as the goods accumulate upon it. Owing to the variations which occur in its position it must be driven by mechanism which will admit of extension or contraction. le have shown mechanism consisting of a belt M2, passing around a pulley k12, affixed to a shaft hm. This shaft is journaled in the bracket h2 and has combined With it a convolute spring hl, aflixed at one end to it and at the otherl end, as shown, to a spring-barrel,

which is rigidly secured to the said bracket or an appurtenance thereof. This spring will be Wound from time to time by hand when it is employed as the agent for rotating4 the take-u p roller H2. The belt k12 also passes around ap'ulley h16,aliixed to one of the journals of the take-up roller H2. Combined with the belt are pulleys h, one or more of which are bodily movable under the influence of a spring to take up and let out the belt, as may be necessary to admit of the movements of the take-up roller H3 along the slots of the brackets h h2 in consequence of variations in the amount of goods wound upon said take-up roller.

I designates a guide, which may be made of sheet metal or other analogous material. At one end it extends around the work bed or support D at a sufficient distance therefrom to admit of the passage between it and the Work bed or support of the goods which have been quilted. From this end it iiares outwardly and gradually becomes flatter and flatter toward its other end, which will be in close proximity to the feed-rollers H H2, or if they be omitted then in close proximity to the take-up roller. The function of this guide is therefore to receive the quilted goods while they are in the curved form which they assume during the time they are upon the work bed or support and to gradually straighten them out widthwise, so that they vmay pass between the feed-rollers or upon the take-up roller.

J designates a delivery-roller, which is journaled in brackets j '72, affixed to the rotary support F2. It is journaled in slots which extend lengthwise of the brackets and have combined with them springs y2, whereby the roller will be drawn toward a bar or plate j, which is affixed to the rotary support F2or to its bracketsj These springs provide' for the adjustment of the rollerinto different positions as the amount of goods upon it varies. This roller need not be driven, as it will derive a rotary movement from the drawing or feeding of the goods along the work bed or support.

K designates a guide, which is or may be very similar to the guide I, heretofore described. The goods enter this guide in a comparatively flat state, and, owing to the contraction and bending of the guide toward its other end,will be graduallybent around into curved form, so that they may, when delivered upon the work bed or support, conform to the contour of the latter.

The mechanism which we have now de.-

IOO

scribed may he sufficient for feeding the goods in the required manner; but we have shown additional feeding mechanism for the purpose of feeding the goods lengthwise of the work bed or support. The mechanism just alluded to has not, however, the function of feeding the goods circumferentially of or around the work bed or support.

L L2 L3 designate a carrier which conforms to the contour of the work bed or support. As shown, it is composed of two rings L L2, surrounding said work bed or support, one near each end of the opening (Z thereof, anda number of rods L2, united to said rings and extending between them, so as to secure them together. The goods pass over the outersurface of this carrier. Around the rings L L2 bands or'straps L4 L5 extend. The ends of these straps are secured to rods L L2, which are connected to the ends of levers L2 L2. The lever L8 is composed of two parallel and similar portions Z Z2. These portions at t-he forward end are secured to the rod L and at the rear end to a tubular rod L10. This tubular rod Lw is a fulcrum-piece of the lever L8 and fits upon the rod which is secured to side pieces of frame-work B of the machine. The tubular rod L10 can slide upon the rod last named length ise. Between the ends of the tubular rod L10 and the side pieces of the frame adjacent thereto we interpose springs L12, here shown as of spiral form. They serve to maintain the tubular rod Lw, and conse quently the lever L2, in its normal position.

The rod L2, to which the lower ends of the bands or straps LL L5 are secured, is integral with or atiixed to the lever L. This lever Lg is composed of two similar and parallel portions Z3 Z4, which are secured at the rear end to a tubular rod LU. This tubular rod, like the tubular rod L10 of the other lever L2, is fitted to slide lengthwise upon a rod supported by side pieces of the frame of the 1nachine. Springs L12 are interposed between the tubular rod Lll and the adjacent side pieces of the machine-frame to hold thelever LS normally in position.

The levers L2 L2 are shown as united by pairs of togglelinks. As shown, the portion Z of the lever LS is connected to the portion Z3 of the lever L9 by one pair of toggle-links N N2,"and the portion Z2 of the lever L8 is connected to the portion Z4 of thelever L9 by an* other pair of toggle-links N2 N 4. By deecting either pair of the toggle-links the levers LS LJ will be swung nearer together and the bands or straps L4 L5 will be correspondingly tightened around the rings L L2 of the earrier. lVhen this occurs the goods will be gripped tightly between the bands or straps and the carrier. As the levers are free to move sidewise, they will be moved sidewise by the action of the cam which detlects the toggle-links, providing the throw of the cam be suiiicient not only to deflect either pair of links sufciently to cause the gripping of the goods, but also subsequently deflect the toggie-links bodily to one side. Such action will cause the movement of the levers to one side against the resistance of the springs L12 L12, which oppose the movement of the levers in that direction. It will therefore be obvious that not only will the goods be gripped, but that they will also be fed lengthwise of the work bed or support.

lVe provide two pairs of toggle-links in o1'- der that a feed of the goods may belobtained in either direction lengthwise 0f the work bed or support. A separate cam will bc employed for each pair of toggle-links, and these cams will operate in different horizontal planes in order that they may not interfere with the toggle-links, with which they are not intended to ceac-t. Te have shown a cam consisting of a disk O, affixed to the shaft Gr and provided with an anti-friction roller or bowl projecting beyond its delivery. Then the anti-friction roller or bowl O is arranged above the disk, it will operate one pair of toggle-links. If removed and placed below the disk, it will operate the other pair of toggle-links. In either case it will not only eifect the gripping of the goods between the bands or straps L4 L5 and the rings L L2, but it will also effect a movement of the goods after they are gripped in the direction of the length of the work bed or support. Vhen the bands or straps L4 L5 are moved lengthwise of the work bed or support, the carrier L L2 L3 will be similarly moved because it becomes fixed to the bands or straps when the goods are gripped. After the movement of the goods lengthwise of the Work bed or support, which is elfected by the cam O, this cam will pass beyond the pair of toggle-links with which it operated, and thereupon the levers LS L2 will be released, the straps L1l L5 will be relaxed, and the goods and carrier lef t free. The spring L12 L13 will then move the levers L8 L to their normal position, where they will be ready to again operate upon the goods to feed them along the work bed or support. The carrier will be moved to its normal position by means of a spring P, connected at one end to a lug projecting from one of the rings L L2 through a slot which extends lengthwise of the work bed or support and connected at the other end to a rod P', which may be engaged with or disengaged from the work bed or support at the nearer extremity thereof. This spring will draw the lOO IIO

carrier toward the end of the work bed or support to which said spring is connected. A similar spring P2 is connected in like manner to the other of the rings L L2 and' connected to a rod P2, that is capable of being engaged with or disengaged from the nearer end of the work bed or support. The object of employing two springs and two rods and providing for engaging and disengaging either of the rods from the work; bed or support enables the carrier to be returned or moved in either direction lengthwise of the work bed or support after the bands or straps Ll L5 shall be relaxed, and hence adapts thecarrier for use in feeding the goods in either direction lengthwise of the work bed or support.

"We have only described mechanism for moving the work to be quilted lengthwise of the work bed or support while being carried around the latter in relation with parts shown at one end of the work bed or support. The mechanism which has thus been particularly described, consisting` of feed-rollers, take-up roller, and mechanism for driving these rollers, will be duplicated at the other end of the work bed or support whenever it is desirable to provide for the longitudinal feed of the i goods in each direction axially of the work bed or support.
