EPPA H. RYON, 0F WALTHAM, MASSACHUSETTS, ASSIGNOR TO CROMPTON' & KNOWLES L'OOM WORKS, A CORPORATION OF MASSACHUSETTS.

WEFT-REPLENISHING LOOM.

To all whom it may concern:

Be it known that I, EPPA' H. RYoN, a citizen of the United States, residing at Valtham, in the county of Middlesex and State of Massachusetts, have invented certain new .and useful Improvements in lVeft-Replenishing Looms, of which the following is a speclfication.

My invention relates to automatic weft replenishing looms of thetype shown and described in U. S. Letters Patent, No. 933,492, and particularly to the bobbin selecting mechanism combined with the stationary magazine shown and described in U. S.

Letters Patent, No. 972,722, which mechapatented in U. S.Letters Patent, No. 600,488,

so that said selecting mechanism will be operated by said box operating mechanism. The bobbin selecting mechanism consists in this instance of four vertically moving bars, one for each compartment or guide-way of the magazine. These bars are loosely supported in guides, to have an up and down movement communicated thereto by operating fingers, above and below a projection on the bar. The lower end of each bar has pivotally attached thereto one arm of a rocking support or cradle. and the vertical movement of a bar communicates to said support or cradle, a rocking movement. according to the vertical movement of said bars! The rocking of a cradle causes the selection of a bobbin from the magazine. .to be transferred in the usual way.

' The object of my invention is to improve upon and simplify the construction of the bobbin selecting mechanism above referred to. Instead of having two sets of fingers, which operate the vertically moving bars up and down, in order to operate the cradles to drop a bobbin from its compartment to the discharging end of the magazine, I use in this instance one lever only, which is operated by a single cam, and which, on the indication of the substantial exhaustion of filling on a bobbin, first moves the vertically extending bar upwardly, to rock a cradle and allow the lowest bobbin in a I Specification of Letters Patent.

Patented June 25, 1912.

Application filed September 10, 1910. Serial No. 581,387.

compartment to move down the distance of one bobbin and be held there, and then, when the corresponding shuttle returns to the magazine end, moves the bar down again to rock the cradle and allow the bobbin to drop down to the lower discharging I end of the magazine, preparatory to being transferred into the shuttle, as usual.

The further object of my invention is to combine the bobbin selecting mechanism with the shuttle box operating mechanism of the Crompton type above referred to, through intermediate connections, so that said selecting mechanism will be operated by the operation of said box operating mechanism.

I have only shown in the drawings detached port-ions. of a weft replenishing loom of the class above. referred to, with my improvements applied thereto, sufficient to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawings :Figure 1 is.

an end view of a loom of the class referred to. showing a part of the inner end of a stationary magazine, and parts of the selecting mechanism, and intermediate connections to the compound levers of the shuttle box operating mechanism of the Crompton type referred to, and also the lay and movable shuttle boxes; the shuttle boxes are. shown partially in section. Fig. 2 is an inner end view of the magazine, and the bobbin holding and selectingmechanism of my improved construction. Fig. 3 is a front view of some of the parts shown in Fig. 2. looking in the directionof arrow (1, same figure. Fig. 4c is a section, on line .4. 4, Fig. 2, looking in the direction of arrow 7), same figure. Fig. is an inner end view of a detached portion of the magazine, and the transferring mechanism, looking in the .direction of arrow 0, Fig. 3. Fig. 6 shows an enlarged scale ofthe compound levers shown in Fig. 1, detached. Fig. 7 shows a plan view of the compound levers shown in Fig. 6. looking in the direction of arrowrl, same figure. Fig. 8 shows some of the parts in Fig. 3, in a'diiferent position. Fig. 9 corresponds to Fig. 8, but shows some of the part-s in a differentposition, and. Fig. 10 corresponds to Fig. 9, but shows some of the parts in a different position.

In the accompanying drawings, 1 is the loom side, 2 is the breast beam, 3, (Fig. 5),

the lay beam, having a stationary shuttle box 4 on one end for a shuttle 5. On the end of the breast beam 2 is secured a stationary stand 6, which has rigidly connected therewith the inner end 7 of the magazine,

sists of a rocking support or cradle 8, pivotally mounted at the lower part of the magazine. The transferrer arm 9, (Fig. 5), has a downward extension 9' thereon which carries a dagger 10, which is adapted tobe moved into the path of and be-engaged by the hunter 11 on the lay beam 3, in the usual the loom side-1, and extending'out therefrom is a'stan'd 12, (Fig. 3), which forms a support for thenfeeler guide 13 of thefilling feeler or detector, which in this instance may be of the type shown and described in the Letters Patent, No. 972,722, above referred to, and is notparticularly shown" in the drawings. The feeler or detector is adapted to operate the upright lever 14, which has its hub 14' secured on the shaft-'15, which is loosely mounted in bearin 12 and 12", on the stand'12. A helica ly coiled torsion spring 16 encircles said shaft .15, to yieldingly hold the lever 14 toward the feeler guide 13; the other end of the shaft 15 has secured thereon the hub 17 of an upright lever 17. The end of said lever 17 is pivot-ally connected to a horizontally extending rod) or plunger 18, (Figs. 2 and'5), guided at 12" on the stand 12, and forms a holding point, or fulcrum," for the ,end of a horizontally extending lever 19,

(Fig. 3), which has one end extending into ,the. upright slotted portion 12 on the stand 12.

A rocking motion is communicated to the lever 19 by a cam and lever on the loom, not shown, through connector 20, which is provided with a rod head 21, and is vertically guided in a boss 12 on the stand 12. The upper yoke-shaped end 21' on the rod head 21 has pivotally connected thereto the hub of the lever 19, to rock said lever, and on the substantial exhaustion of filling in the runningshuttle, through the indication of-the filling detector, to operate a cradle to drop a bobbin to the discharging end of the magazine, as shown and described in Letters Patent, No. 933,492,.above referred to.

The upright vertically moving members or bars .22, which in 'this instance form a part of my improvements, are provided with weighted hooks 23 at theirv upper ends, which hooks are adapted, on the downward movement of a bar 22, to. engage and rock a lever 24, (Fig. 10), which has its hub 24 secured to the rock shaft 25. The vertically moving members or bars 22 have in this instance two notches 22*, on one edge thereof, see Fig. 8,,and a spring actuated plunger 22* is adapted to enter either 'one' of the notches, and to act as yielding means to retain a member or bar 22 in its raised or lowered position, as fully shown and described in Patent, No. 933,492, above referred to.

The rock shaft 25 has secured thereon the hub 26 of an arm 26, (Fig. 3). A stud 2T enters a hole in a block 28, which is adapted to loosely slide in an elongated opening29 in a lever 29, which has its hub 29" loosely mounted on a stud 30." A helically coiledexpansion spring 31 bears at one end against the block 28, and at its other end against the hub 29" of the lever 29, and acts to hold and lock the lever 26, and lever 29 in their upper and lower position. Extending out from the hub 29" on the lever 29 is a second arm 32, the outer end of which'is pivotally connected to a downwardly extending connecting rod 33; the lower end of the connecting rod 33 is provided with a vertically extending plate 34, (Fig. 5), which is adjustably secured on the rod 33. The plate 34 has anelongated opening 34, into which extends a stud 34% on the stand 12, which is adapted to hold and guide the plate 34 in a vertical plane. A projection 34 extends from the plate 34 and belowthe dagger 10, which when the plate 34is raised, causes the' dagger 10 on the transferrer arm 30 to be raised into the path of the hunter Men the lay beam 3, to be'engaged-by the hunter to operate the transferrer arm 9, to transfer a bobbin into a shuttle 5, in the usual way.

The bearings 7' on the magazine have loosely mounted therein the longitudinally moving rod 36; one end of said rod 36 has a collar 37 secured thereon, which has an annular groove 37', into which extends a side extension '38 on one arm of an angle lever 38, which has its hub 38" loosely mounted on a stud 39 carried on a stand 40; the other arm of the angle lever 38 is adjustably connected. through a slot and bolt connection, with the upper end of a wire. 41, (Figs. 1 and 2). connected to one end of a flexible connection or chain 48; 'said chain 48 passes over a guide sheave 49. and over a second guide sheave 50, (see Fig. 1), mountedpn a stand 51 on the left hand loom side, and is .attached to a lever of the compound lever mechanism, to be hereinafter described.

The compound levers are operated through the well known shuttle box operat- The lower end of the wire 41 ising mechanism of the Crompton type,

shown and described in U. S. Letters Patent, No. 600,488, above "referred to. The box mot-ion consists of two mutilated pinions 52, fast. on shafts 5,3, and having movable teeth, which are operated through the pattern indicating surface or chain, not shown, and moved into and out of operative' connection wit-h a master gear '54, fast on the bottom shaft The opposite .ends of the. shafts 53, which are carried on a stand 56, are connected, through crank connectors 57 and 58, with the. box operating lever 59. which, through a link or connector 60, isconnected with the vertically moving rod 61, which supports on its upper end the shuttle boxes 62; in this instance four in number, carrying the shuttles 5. Each shuttle 5 preferably has a bobbin or filling carrier therein of a different color. The lay 3, which is carried on the lay swords 63, pivotally mounted at their lower ends, is operated,'through the crankconnector 64, by the crank shaft 65, in the usual way.

I All of the above mentioned parts may be of the usual and well known construction, and particularly described in Letters Patent, No.v 933,492, and No. 600,488, above referred to.

I will now describe my improvements. One end of the horizontally extending lever 19 see Figs.'8, 9,-and 10 extends, as above stated, within the slotted part 12 and is adapted to bear on its upward movement, in this instance with its upper edge, against a pin 12", and on its downward movement the lower edge rests upon the rod or plun ger 18, in case said rod or plunger is left in the path of the movement of the lever 19, on the substantial exhaustion of filling on the bobbin in the active shuttle. The other end of the lever 19has pivotally connected thereto a rod head 42 on the upwardly extending rod or connector 42. end of. the connector 42 is pivotally connected to a pin 43 on a lever 44, which, has its hub 44' loosely mounted on the rod 36, (F ig. 4), and is prevented from having longitudinal movement on said rod by the two bosses 7 T he lever 44 is provided in this instance with lugs 44", adapted to loosely receive the spring actuated bolt 45, which, through the action of a helically coiled expansion spring 46, when the lever 44 is in a horizontal position, bears against the stand 6 see Fig. 3 to prevent the lever 44 moving downwardly, through the action The rod 36 has secured- 47 see Fig.4. A side extension 47 on the hub 47. extends loosely into a notch or recess inthe lever 44. The up and down movement of the lever ,44 will communi- The upper c'ate, through the extension 47", an up and down movement to the fingers 47.

On the inside of ,the end plate of the magazine 7, and loosely guided thereon, are the four vertically moving bars 22 above referred to, one for each compartment. The lower end of each bar 22 has in this instance the enlarged portion 22, provided- With a slot oropening 22",having an oifset therein, see Fig. 2, to loosely receive the end of apin 8f, which is secured at its other end to an arm of the rocking support or cradle 8. The ofi'set opening 22" acts to rock a cradle 8. and to lock and hold the same in its two positions, on the up and j allowing a bobbin to drop into the cradle,

and on the downward movement of the bar 22, through the partial rotation of the era dlc 8, the bobbin will be released and dropped to the lower discharging end of the magazine. Atthe same time, on the further downward movement of the bar 22, the weighted hook 23, at its upper end, operates the lever 24, and' through the intermediate connections above. described, raises the dagger 10 into the path of the hunter 11, inorder to transfer a bobbin into the shuttle.

I will now describe the mechanism for controlling the longitudinal movement of the rod 36 of the bobbin selecting mechanism. The chain 48, above mentioned. is connected to one arm of a lever 66, see Fig. 6; said lever66 is-piv'o-tally mounted on a.

stud 67 on an arm 68 on the bearing 68 of the bottom shaft- 55. The oppositeend of the lever 66 carries a stud 69, on which is loosely mounted the hub 70' of a balancing lever 70, comprising two arms which have the'engaging ends 7.0 and 70", said engaging ends in this instance, are adapted to ride upon the periphery of two cams 71 and 72, respectively, which have their hubs 71 and 72' secured on the shafts 53 of the mutilated pinions 52; The revolving of the mutilated pinions 52, to operate the box motion lever 59, will, through cams 71 and 72,

operate the balancing lever 70, and the le ver .66, and communicate. through the cha1n48,

and angle lever 38, a longitudinal movement 10 the rod 36 in one direction, to cause it to be moved, according to tl1e|1 iove1nent of the. shuttle boxes, for the selection of the bobbins'from themagazine. A helically coiled -tension spring 38", see Figs. 1 and 2, at-

shown and described in Letters Patent, No.

972,722, above referred to, will engage at its inner end the filling in the shuttle, as the lay beats up, and be moved backwardlytomove the lever 17, so that the rod or plunger 18 is moved out of the path of movement of the free end of the lever 19, to allow said end to freely move downwardly to the position shown in Fig. 8, thus leaving the lever 44 and finger 47 at rest, in their horizontal or center position, as shown in Fig. .8.

In case the filling onthe bobbin in the active shuttle is practically-or substantially exhausted, then as the lay beats up, the filling feeler does'not operate the lever 17, and the rod or plunger 18 is in the path of movement of the 'free end .of .the lever 19, as shown in Fig. 9, thus forming a fulcrum for said free end, and allowing the opposite end of the lever '19 to be moved downwardly, to operate the. lever 44, and the finger 47 to move upwardly a vertically moving bar 22, to allow a bobbin to drop into acradle 8. On the next upward movement of the lever 19, its free end bears against the pin 12", and causes the opposite end of the lever 19 to move upwardly,'see Fig. 10, to operate the lever 44 and finger 47, and on the same position of the drop shuttle boxes, to move downwardly the vertically moving bar 22, to drop a bobbin to the discharging end 7 of the magazine, and at the same time raise the dagger 10, asabove stated, into the path of the hunter 11, to

transfer a bobbin into the active shuttle.

It will be understood that the details of construction of my-improvements. may be varied if desired.
