SYLVANIA nooilt,

A plication filed Decanter 5; 1528; steameates;

This invention relates to a loom for Weaving. I In the standard loom which is inalinost" universal use today, there is a warp beam which provides; the Warp threads'which are carried by the heddles and alternately raised and lowered to provide the required sheds into which the'weftthread's are woven.

The weft threads are provided by means of shuttles containing bobbins wound with weftthre'ad and which are passed to and fro through the suceessive'warp sheds by means of picker-sticks which are operated by cam mechanisms. I

' These bobbins are each wound with a diferent coloredweft and the shuttleboxes usually n' ove vertically in' order to bring the proper shuttle to a position inline with the shed of the warp. I

The bobbins which are carriedby the shut ties contain but a" very: small amo untoi' thread and the shuttles are very carefully packed with felt or other soft material which exerts'a retardingaction' on the thread of the bobbin and preventsit fromfeeding there from in any greaterquantity than desired.

7 These bobbins, on account of the small amount of thread" which they carry; are' re quired to be changed quite f'requentlyso that there is great likelihood otdefects' 1n the cloth atthe ends of'theseweft threadsywhilethe greatestloss arises froin'the necessity of Various deviceshave been recommended tor eliminating the necessity ofstopping the loom and thereforeyincreasing theoutput; and among which will be found my-copendingapplic ations, Serial No. 224,342, filed Denaazryeig ezs; I I I I ceniber 1:927, and Serial No. 250,790; tiled shuttles and shuttle boxe's ha've' benf en lrely I eliminated and the weft threads are selected and passed through the warp sheds 'by' rec1p-,

The

27 hand rail 28, reeds 29, heddle frames 30,

With the single exception of the lay, these ary manner and operate precisely the same as they do in the conventional loom.

The left hand end of the lay, as shown in Figure 1, is extended, as at 36, and the right like view with the thread and.

100111 has a frame'2l, arches22, dobby. 23, pattern cylinder 24c,'breast beam 26, lay

' and left hand ends of the lay are provided But the warp may contain as many colors as desired. and patterns may be woven into the fabric F by means of the pattern chain 40 which controls the operation of the acks 45.

In the case of a plain or striped fabric, the dobby, pattern cylinder, and pattern chain may be omitted and two heddle'frames 30 may be operated by a cam or other mechanism for forming the successive warp sheds.

The shuttle receivers 38 and 39 are provided, respectively, with picker sticks 11 and 42 which areoperated by cam mechanism, as in the conventional loom. On the right hand side of the loom is a platform' 43 on which is mounted a cone box 441Wl113l1 is adapted to contain a cone of weft thread, the feed-0E strand of which is indicated by the letter X.

By reference to Figures 2, 3 and 4, it will be apparent that theweft thread X passes through a guide 16 mounted on the 100m frame. andthence passes to a horizontal guide 47 illustrated in Figures 2, 3 and 4, and mounted on the front edge of the frame.

' From the guide 47, the weft thread makes a the inner edge of the upper end of the breast" beam and fromthence passes through the needle 53 and then to thefab'ric, as shown .in

Figures 6, 7 and'8. The needle 53 is formed of a piece of tube and has a cut-out portion .54 for receiving the thread. This needleis fastened to the inner edge of the breast beam 26, as shown at .56 in Figure 2.

.fThe main shaft 57 of the its right hand end with a cam' 58.. This cam.

100111 is set in V motion bythe operation ofthe shipperhandle has a dual purposeand one is to operate the clamp discs 49 and i 51 which shown in Figures 3 and 4. i

I An ogee "crank. 59 is pivotallyfastened to theframe-21 at the point'61 and the upper are clearly 1:20, 7

arm 62 of this crank engages the 58, while 7 the lower arm 63 hassecured thereto, by'any and in. linewith the breastbeaih 26, and is v. suitable means, a wire 64 which passes over a V then connected to'th'e shafton one end at which the clamp" disc 49 is mtuntd;

By reference to Figure '9', it will be seen that the clamp disc 51' is securely mounted in a pedestal 69fby the set screw 71', while the clutch disc 49 is mounted 'onthe shaft 68" which is slidable in the bearing pedestal 72 and between this pedestal and the clamp disc 49 and 's'iir 'roundingthe shaft, is a" spiral spring 73'; v r

The weft thread X rwhich is being fed from the'cone 130K544, will always pass" between the discs 49-an'd 51- and when there is no tension on the wire 64 so as to compress the spring? 3, the said spring will press the disc 49 firmly against the di'sc 51 and therefore cla'mp-theweft thread'between said discs.

Let u's'con'si'der that a shuttle,rsuchas that shown in F ig ures ll, 12'and 1'3, is being used for weaving-1 the weft thread into? the warp. Consider that the-shuttle is in the right hand shuttlerece'iver 38. The ca1n5 8 engages a follower 74 which is pivotally mounted on the frame 21'; at 7 6. The outerend'of this follower is connected by a spiral spring 77 to the floor so that thefollower Will at all times bear on the earn 58 intermediate the pivotal point 7 6 1 and the outer end" connected with thespring77; The inner end of the follower ispivotally connected at 78 to a-rod' 79 which extends upward through a bearing 81, fastened to theinner side of the lay 27.

Secured'to'the upper end of the 'rod 79, by

suitablelocking nuts, is a plate 82 which eX- tend's'forward an'd'over the lay 27, and is provided on its inner end with an actuating pin 83fwlf1ich isslidaiblje'in said'pl'at'e by reason of the position of the lo ck nu'ts'84f and the flange nut86. 1

The: actuating" pin 83fjis' steadied in its operation by means, ofthe, annular bearing plate 85' through the horizontal portion of: whichjthe said pin; passes and the" vertical part off fwhichjis fastened t oltheinner' side of the lay".

The actuating piece" is disposed; directly above the. center of the shuttle 87 when the. same is residing ,in; the rightliand shuttle re ceiver 38 andclea'rly shown in Figured The location" of the actuating pin .83 injthis posi tion will force'theplate'82 to be placed awry asshowndirFigures8 and 4,

For this pur-" pose, let usrefer toliligures;6;] and 8.; r In Figure 6the shuttle is at therighthand; side ofthe warp andlthe'needle 53iis fabrlc.

. left hand side of the loom passes the shuttle through the new shed to the position shown 'inFigure .8. The loop which is in the shuttle must now be released and a new loop from the needle placed thereon, as shown in Fig ure 6. Y

. It is apparent from an inspection of the figures above mentioned that a double warp strand is woven into every pick of the To accomplish the result above, described, let us assume that the lay27 is in the position shown in Figure 2. The crank 129 moves about the shaft 131 inthe direction shown by the arrow and by reason of the gears 132 on said shaft and the gear 133 on the shaft 57 the shafts will rotate opposite directions.

In the position of the lay, as shown in Figure 2, the shuttle 87 is just about to be thrown from the right hand side of the loom through the warp shed and by the time the shuttle reaches the receiver on the left hand side of the lay, the crank 129 will have made a little more than one-half of arevolution but the gears 132 and 133 are so arranged that the speed of the shaft 57 is exactly onehalf the 7 speed of the shaft 131.

Consequently, the cam58 will during same period move slightly more than a quarter of a revolution and the cam .1s so timed that at the very instant the shuttle reaches the receiver 39, the said cam will disengage the ogee crank arm 62 and the tension thus being released, the springs7 3 will move the disc 49 firmly against the disc 51 and thereby clamp the thread X. v, d

The amount of thread which has beencarried bythe shuttle in its movement from the right tothe left hand side of the loom will be exactly thatrequired to complete its return to the receiver 38 on the right han d si de of the loom and to draw the same firmly into the selvage which is'being formed on the left hand side of the fabric. i V V. V

' In order tocomplete this return of the shut-;

tle, the lay 27 is moved forward on the swords 31 and on the return stroke and at about the position of the crank shown in Figure 2, the picker stick on the left hand side of thejloom will operate and pass the shuttle back into the receiver 38. At the end of'this stroke the lay will be in about the same position as. shown in Figure 2, but the crank 129 will bea' little more than 180 from the position shown in that figure and the cam 58 on the shaft 57 will be slightly more than 'tion shown;

.j t m the si- As the lay continuesto move'forward the operation of the crankl29, the cam 57 will engage the, follower 74, pulling the for; ward end of the same downward so that the rod 79 ;will bring theactuatin'g pin83 down.

onto the top ofthe inner end of the lever in the shuttle 87. This will compress the spring 98 and raise the pin 96.

At this movement, the selvage heddle 118 is raised and the loop vwhich is designated ward position,the needle 53will have entered the channel 92 in the shuttle 87 and at the right of the pin 96 That part ofthe thread which I have designated 137 in Figure 6 will be drawninto the undercut slot 94 so that the thread will be disposed behind the slight depression 97 into. which the pin extends when the same is lowered,

While in this position the cam 58 ceases to hold the rod 79 down and the spring 77 on the rear of the cam follower 74 will force the rod upward and thereby disengage the actuating pin 83 from the end of the lever 89. The lay then moves to the rear and as it does so, it operates the bell crank 111 through the link 112 and the serrated arm 117 of the bell crank will pull the loop from the hook 126 andlahrush the same over onto the woven fabric As the loom returns to the position shown in Figure 2, the cam' 58 will have'entirely disengaged the follower 74 and will engage the upper arm 62 of the ogee crank 59 and through the wire 64 will pull the shaft 68 carrying the disc 49 outward, thereby releasing the tension on the weft thread X, so that when the picker stick strikes the shuttle, the weft thread may be paid out as required.

The cam 58 for operating theclamp mechaance. v v g If desired, a shuttle such as that shown in Figures 14 to 17 inclusive and designated 141 may be employed. This shuttle has a recess center just above'the bottom portion of this cut-out, is provided on its end with a hook member 147; i e 7 i The body is also provided with a recess 148 and the shaft 146 extends through this recess and is journaled on the other side thereof and on that part which extends through the recess it is provided with a pinion 149. This 142 into which a body 143 ofsome light ma-' terial, such as aluminum, islplaced'. The body 7 is provided with a cut-out portion or recess ;144 anda shaft 146, with its longitudinal pinionmeshes with another pinion 151 in said recess and mounted on a shaft 152 which I V singed off so that the right hand side of the i i fabric will present 7 an even finished 7 appearextends ioversthe inner flat part 153 of the body and is provided with a ratchet-wheel 154.-The1.cut.-out or recess 142 in the.;body
