IMPROVEMENT l N,LOOMS.

Specif cation forming part of Letters Patent No. 19 8,156, dated December 11, 1877 application filed September 8, 1877;

To all whom it may concern:

Be it known that I; WILLIAM RIDING, of Norristown, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification, in which- Figure 1 is a front elevation of a lay of a loom with my improvements attached thereto.

Fig. 2 is a rear view of the same. Fig. 3 is a transverse vertical section of the lay in its forward position, showing the reed unlocked and free to swing; Fig. 4 is a transverse vertical section of the laymidway on its return motion,

showing the reed locked. Fig. 5 is a transverse vertical section of the lay-on its forward motion, showing the shuttle in one of the boxes and the reed locked. Fig. 6is a broken transverse vertical section of the lay, showing the position of the cam H and arm Gr when the reed is unlocked. Fig. 7 is a similar section of the same parts, showing the reed locked. Fig. 8 is a perspective,partly broken. away, of the upper part of the lay of a 16cm,

with a modification of my improvements ap plied thereto as adapted to looms without swell-fingers. Fig. 9 is a broken transverse vertical section of the same. Fig. 1 0 is a broken side elevation of a loom with my improved running-gear applied'the'reto. Fig. 11 is a transverse vertical section of a loom with my improvements for preventing the shuttle from flying out front. Fig. 12 is a perspective of the latter improvements. 7

The first part of my improvements has for its object the prevention of smashes in weaving. 1 3 Myimprovements have for their further object to provide for the ready removal of the reed without taking off the lay-cap, to cause the lay to dwell when the shuttle is coming 'home, and to eifect the rapid starting and stoppage of the loom at proper times.

My invention consists in the novel construction and combination of parts, as hereinafter fully set forth.

Referring to the accompanying drawings,

the brackets. move up and down as upon ways or in guides,

A represents the lay of a loom, and A its cap, I

ing arms 0 c, recessed at c for the reception of the tongues or ribs (1 onbrackets BB ,formed on or attached to the swords A or the backboard may slide in suitable. ways formed on The bar 0 is thus allowed to so as to lock and release the reed B, as hereinafter set forth. Said reed B is heldin the groove a by a slide,a, attached to the lay-cap A by screws a passing through slotted openings in said slide, and by springs a fastened to the lay-cap at a By simply moving this slide upon the retaining-screws, the reed may be easily inserted in or removed from its groove a. The slide also prevents the bar b from binding,the slide and springs being adapted to yield against any tendency to bind.

c are slots or grooves formed in the arms or pendants c, for the reception of the ends of the arms 0' G, which are secured to the rock-shaft or protection-rod D, which has its bearings in hangers d d, secured to the front of the lay, as shown.

E E are other arms, secured to the shaft or rod 1), having their upper extremities curved or bent so as to impinge against the swell-fingers e, which are hinged at c to the shuttleboxes F. I

Gris still another arm, secured to the shaft 1 or rod D at g, projecting rearwardly under the lay, as shown, in line with the side frames of i the loom, so that the anti-friction roller 9?,

with .which It may be provided will ride upon the cam or ridge formed on or attached to said frame, said cam being shown at H.

I is another arm, attached to the shaft or rod D designed to strike the stop-rod K when the shuttle is not home in one of theboxesat the .right time.

The bar (3 is of suflicient lengthto lap upon and serve to hold fast the hinged backs F F of the shuttle-boxes when said bar is elevated, as hereinafter set forth.

L represents the crank-shaft, and l l the cranks and pitmen are so adjusted with reference to the lay that the latter will dwell when the former are moving from their lower to their upper back center, the rear ends of. the

pitmen swinging with-the cranks from theircenters on the pivots 0 The motion of the cranks while the lay dwells, as, stated, iSsShGWIJ: in dotted lines in Fig. 4.

When the lay is beating up the weft the shuttleshould be in one of the boxes. F, and when thus in its box the swell-finger of said box is pushed by it outwardly against the adjacent arm E, causing the shaft or rod D so tobe turned or rocked as to throw upthearms- C O and elevate the bar 0, thusnnaking fast or looking the pivoted reed; 13.. Should the shuttle, vhowever, at this time be upon: the race,'instead of in one of the boxes, the arms E E will push the swell-fingers intotheirboxes, the movement of said arms. being caused by the'rocking of the shaft or rod D,produced by the weight of thefbar O on thefarms O" (7). Or, in other words, if the shuttle--v bein its proper placein theibox at the time indicated, it will, by preventing the yielding of the swell-finger, and the inward movement of the arms EE, hold the bar 0 elevated and keep the swinging reed locked. But if it be not in one of the boxes at thattime, the. bar G willfmove down. by its own gravity, the arms E'then meeting withno resistanceback of the swell-fingers, and the reed' willbeffree to swing back andallow the shnttle-toescape. When, however, the shuttle 'is picked. and leaves its box, the bar 0 is then; prevented: from descending far enough toclear'the bottom; of the reed, by'reason of the anti-friction. roller g mounting the cam. or swellf H on. the.

frameB as the lay continues to move back,

thuskeeping the arms 0' Cf elevated,and-.the.

sliding bar G sufficiently raised to: lock the reed while the shuttle is moving across the race.

When the shuttle does not come home at the right time, the bar 0 slides down. and the reedBisthen free to 'swingbackwardly, thus.

allowing egress. for the shuttle, and. avoidin g, a. smash. The downward-movement of the bar.

0 also leaves the hinged backs F F- of the boxes F F free to swing backwardly, thus further facilitating the recession, of, the. shut,- tle from the race. 7

. The contactlof thecams. H with the. roller gf'has the, effect of rocking the shaft D-in such.

manner-as tocause'the arms tobe drawn,

away from the swells c e, (which, withmy im-v provements, m ay beun'providedwith. springs,) so, that when, the shuttle is being. pickedsitis not clamped by said fingers, but isfree to receive and acquire thefull force of the blow on stroke of the picker, and is, thusenabled to travellwithgreater momentum. and rapidity, accomplishing, a j higher number of, picks per, minute" than is possible in looms of, the com.- mon-constructiom I for the shuttle to come home to it's. place in the box than if such provision were not made, while at the same time the speed of the crankpicks. per minute. decreased. l Ihave describedthe foregoing improvements as applied to a loom having swell-fingers and a gprotection rod on the front of the shuttle-box, but they are equally applicable to looms the shuttle-boxes of which have no swell-fingers, Y but are provided with a protection-rod located in the rear of said shuttle-boxes. I The application of my improvements to looms of this latter construction is illustrated in Figs. 8 and 9, wherein R is the protection- 2 rod, sustained in boxes 4" r on the lay-swords A A ,,and S Sare, the arms. secured thereto, curved or bent at their upper extremities,

boxes F F, so. as. to impinge against the shuttle. T is the sliding bar, which. looks the, :reed, and U' U the arms, by means of which it ist sustained, said armsere'stingv on other short :arms '1. '23, fast on'the protection-rod R, the arms U U beingpivotedin bearings u u: secured to the front of the race or lay. w

The other parts of the loom, notably the arm R? with roller 7: and cam: 13?, with the ,modifications just described, willbe substantially the same. as-those first above mentioned,'. gand' the: operation will produce the same rejsults asthose already set forth-namely, the: ireed will be lockedv when the-shuttle is propierly moving across the race, and when. said, shuttle oomeshome at theright time toitsplace gin the boxes, while said reed will be released gby thedownwardmovement of the'shdingbar, iand allowed to swing back for the escape of Ethe shuttle, if the latter does 'not come home-v gor reach, its place inthe boxes at the proper fitime.

Forheavy looms, an additional shaft, V, haviing, a gear-wheel, o, meshing with thepinion, L. on the crank L,may beemployed.

; When the. shaft V is employed, the pulley Iill thereon for the driving-belt may be but half- ;the size of that usually. employedon thecrankshaft L,as,.for instance, where. apulley twenty ;in.ches-.in diameter has been employed on-said ,beused onthe supplemental shaft V., This gwill give, say,twice the ordinary speedltosaid shaft V-i. 6., twice theordinary speed of the crank-shaftandcorrespondingly quicken the shipping of the runnin gbelt onto the pulley v. This will insure the almostinstantaneous start ing of the loom by the power used for drivin git, and dispense with. the weavers assisting said startin g. by hand, as has, been'heretofore found j necessary. So, too, ,as there iseno banging with a. loom'of. this construction, and. as. the unshippingofithe belt owingto-thesmallsize and. rapid; motion of thcpulley v, is almost :instantly efiected, all backlashv is avoided: In every case the shaftV should begeared so as tomove much. faster-4'. 6., make morerev- The dwell of the lay permits. a longer time shaft is not diminished, nor the number of which enter openings f f in the-back of the Eshaft L,,onc ofT. butten inchesdiameter need 19s,1 5e V 3 olutions per minute-than the crank-shaft L;

in practice, I should say, three to four times as fast as the latter. A further object of my invention is to prevent the shuttle from flying out at the front of the loom, breaking the yarn or warp, and endangering the life and person of the weaver. This part of my invention consists in the provision of a bar, which rests upon the yarns,

. above the race, in such a position as to prevent the shuttle from flying out front, said bar being so arranged andoperated that it will be in the described position while the shuttle is being picked and moving across the race, but

will be lifted up fiom the yarns, so as to leave free access to the latter by the weaver when the shuttle is resting in the box.

In Figs. 11 and 12 of the accompanying drawings, W represents a bar parallel with the race, and sustained upon two curved arms, w w, which are secured to a rock-shaft, W, having bearings in or upon the swordsA w is an arm, having at one end an eye or collar, w, and set-screw w, by means of which it is secured to the shaft W, and at .the other end an anti-friction roller, M. w is another arm, rigidly secured to the shaft W, andXis a spiral. spring, (ora weight may be employed instead,) fastened to said arm, and to one of the swords A at ac. The object of this spring is to keep the shaft W in such a position that the bar W will be held elevated from the yarns when not depressed by the means now to be described. 7

Y is a cam or eccentric on the shaft L, and Z a lever pivoted at z to the frame-piece B and extending forwardly so as to rest on said shaft L. The forward end of said lever is rounded, as shown at z. Whenthe lay moves back, the roller "w meets the lever Z and rides upon it, said lever being then raised by the cam or eccentric Y on the shaft L. This causes the shaft W to be rocked and the bar W to be lowered upon the. yarns. The shuttle is now picked, the bar W remaining in the lowered position, just described, until the shuttle has crossed the race. By the time the shuttle has passed over the race the cam Yhas moved from under the lever Z, allowing the latter to fall and the shaft W to be rocked under the influence of the spring or weight X, causing the bar W to be raised from the yarns and out of the way of the weaver, if he-wish to obtain access to said yarns. Before every pick the barW is lowered, and after every pick it is elevated, as described.

I have illustrated 'the parts just described 4 and shown in Figs. 11 and 12 as in position for operation when the pick is made with the crank on the lower center; but said parts may be arranged to operate in the same manner and with like results when the shuttleis picked with the crank on the upper center, by placing the cam or eccentric Y on the opposite side of the shaft L--i. 6., diametrically opposite the position shown.

What I claim as my invention is- 1. The combination of the lay-cap A, having groove a, the removable reed B, and retaining-slide a, substantially as described.

2. In combination with the pivoted or swin ging reed B, the bar 0, sustained upon arms 0 O, rock-shaft or rod D, arms E 'G, swells e, and cam H, the several parts being constructed and arranged substantially as described, whereby the reed is locked and the swell-fingers relieved upon the back-stroke of the lay, and the locking device is, upon the beat up, placed under the control of the boxswell, as and for the purpose specified.

3. The bar W, located above and parallel with the race, and adapted to be moved down I to rest upon the yarns, as and for the purpose described, in combination with the shaft W,

curved arms 20 w, lever 20 and a cam for actuating said bar, as set forth.

4:. In combination with the bar W, the shaft W, having arms w, 10 and 10 spring or weight X, lever Z, and shaft L, having cam'or eccentric Y, the several parts being constructed and operating substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 24th day of April, 1877.

WILLIAM RIDING.
