- o ali lwao-.fn 'It may @encara 'i it tnown that I, EDWARD S'ro'rz, a citizen ,bf the `Republic of Switzerland, re-' siding at Philadelphia, inthe county of hiladelphia and State of Fennsylvania, have invented certain new and useful linprovenents in Looms, of which the J)following is a spccii'ication. l r

This intention is an improvement on that forming the subject of my U. S. Lett-ers Extent llo. 960433Wherein is set forth a race for the shuttle in a loom composed of a number or spaced Wires forming members which supportthe'` shuttle in its passage across the lay or hatten and permit the lower threads of the warpshed to fall below the shuttle-supporting surface ot said rase, so as notv to be abraded by the shuttle in. its travel. ln my said patent-ed construction, although the shuttle-supporting members are made as` 'narrow as possible so as 4 to ifacilitate the downward entry of the threads between them, a thread occasionally catches and ,remains snp-ported thereon and thus becomes cutl by the v shuttle whenittrayels orer'the bat-ten: To give the said members sharpened upper edges would obionsly be impractical because' they wouldv soon worn broad or at-byithe shuttle. According tovthis invention, A'said-race has its members formed With-A 'properly shaped 'upwardly project-ing parting devices or spurs. Thesel l prefer to place forward et the reed and back of the shuttles path 35 of travel. and in that case they become userul to aford a back support for the shuttle, keeping it out of contact with and hence preventing: its Wearing or injuring thedents of the reed. ln order that the race, 'so construc"ed and arranged,J may not interfere with die beating-up function or the reed, l

spurs aforesaid below the plane of n at 'the moment of beating-up.

Fi 1re i is a front elevation of a loom cond in accordance with the present inthe jiront portion being removed;

^ No. means for vde'pressing it so as tok ln the loom frame als arranged to oscillatein the usual manner the betten driven from the crank-shaft c through the pitinen d. The shuttle e is reciprocated from one shuttle box f to the other by the usual mechanism including picker-sticks g, rock-shafts )t connected with the picker-sticks by the straps z', and tappet-shaft j for alternately ,actuating said rocloshafts, said tappetshaft being connected With thevjcrank shaft bythe gearing lo.

Z is the breast-beam. The body part a of the batten is a suitable length of material having a longitw dinal depression or recess m and its ends raised. The depression 'm receivesthe, shut'- tle-race (to be' described) and in order to compensate for the loss of Weight thus effected I prefer to niakefthe body part a,"- of the hatten of metal, leaying only the shuttls-boxes f j', which are suitably fitted on the ends of the body part a', of Wood. (See Fig. Il.) l

he recessed portion'of body part a of the batten is penetrated' by two vertical rods n depending from a horizontal bar o and forming therewith a structure adapted to reciprocate vertically, being` normally dcpressed by springs p coiled about the rods a and interposed between body part a and collars q. adjustably secured on said rods. The lower ends of the rods are pivotally connected to the front ends of loyers '7' havf ing their fulcrum-bolts s vertically adjustable in the stands t and carrying on their rear ends the shoes u adapted to be simultaneously engaged (to rock the levers r and g raise the rods a1, and bars o) ,'.the 'cams 1: 'yon the tappet-shatt y. said shoesbemp; To

cured'to the levers by bolts Iw penetrating longitudinal slots a in said levers so as to be adjustable.

The bar o carries the'aforeineutionedshut tlc-supports which go to orrnthe shuttle-I race. These are securedto the bar in spaced relation to each other, extending longitudinally'o the warp threads, and each is sufiiciently thin so that it may enter between two threads 'of the Warp Without undue disturb'- ance thereof; 'their top surfaces or edges are Y* arranged all in the 4saine horizontal plano and' are preferably straight, and said supports are of such height that when they are raised to their upward lnnrt by bar o their said surfaces or edges are hush 'with e. boxes f. Each has an upslanding sharpened spur or warp-parting projection. Referring to,Y Fig. 5 one such shlittle-support is showin as consisting of a blade g/ having at the rear end thereof the opstanding tapered portion e' forming the aforesaid warp-parting projection or spur; in Fig. 6 the shuttle support comprises the strip Q having the integral upstanding tapered portion 3 (to form said spur or projection) and the angular wire 4l fitted at its ends into strip and the portion In each ini-hace, a. downwardly projecting flat tail or lug is provided whereby, by a bolt passe-d through it and the bar o, the shuttle-support is removably secured t said bar. fis will be explained, the reed is set back in the hatten so that its front face is not as is usuallj the ease) flush with the back surfaces of the shuttle boxes. The reed is therefrnfe not subjected to the wearing contact of the shuttle in its passage across the hatten, but instead the shuttle is supported it the back by the spurs or projections of e shuttle-supports, which for this purpose preferably have broad flat front faces (Figs. 5 and G) arranged flush with the baclr surfaces of the shuttle boxes.

The reed, designated 7, is supported thus: .di substantially U-shaped frame 8 is secured by its lateral ears 9 to the upper ends of the lay-swords 10 carrying the bat-ten o, and the horizontal bar-portion 8 of this frame e forms one part of a clamp for the lower edge of the reed,. the other part of such clamp being the bar 12 pressed toward bar 8 by the springs 13 interposed bet-Ween bar 12 and pins 111 set in the ends of studs 15 projecting rearwardly from bar 8 through bar 12. At the top of frame 8 is secured a cross-bar4 16 slotted on its under side. The upper edge of the reed being entered into the slotted bar 16, its lower edge.is fitted be'- tween the bars 8 and 12 and held by their clamping action.

17 designates angle brackets to support the frame S against backward displacement when the reed comes against the cloth.

Operation: lVhen the warpV shed is open and the sluittle is thrown across the batteri Vshed have been parted at intervals by the spurs or projections of the said shuttle-supports, and the race formed byl the top surfaces of said shutile-supports stands somewhat higher than the plane of said threads (dotted lines, Fig. et). The shuttle, when thrown, thereforetravels through the shed '1 wit-hout eontacting with and abrading 01` tions out of interposed relation to the remi and the cloth and allow the reed to beat up the filling to the fell of the cloth.

Having thus fully described my invent ien, what I claim as new and desire to seein, by' Letters Patent is:

In combination, the hatten-stroeture includingthe-shuttle boxes, the reed and the shuttle, said batteri-structure having a shuttle-race disposed between said boxes and including spaced sluittle-supports arranged in a series extending longitudinally' of the batten and each support. having an upwardly tapering warp-dividing projection extending upwardly from the shuttle-supporting surface thereof, substantially as des ribed.
