Application filed July 20,
As is well known, the usual shuttle motion in looms iso ierated by means of straps either of leather or of web material which, inherently, are materially affected by stretching, due to varying conditions of humidity and wear. hen these straps stretch, naturally they become loose and impart a considerable jerk, to the shuttle, as lost motion is being taken up. This stretching of the straps very materially limits the speed of the shuttle motion, besides which this jerking motion is the direct cause of the breaking of the teeth in the batten rack.
(hie of the objects of my invention resides in a positively driven element, positively connecting the shuttleinotion lever and a batten with a common prime mover.
Another object of my invention is to provide a rigid connection between the shuttle motion lever, and o miiitirin parts therefor, which is in constant relation to the loom frame and held against swinging with the batten.
Another object of my invention is to provide a shuttle motion lover having a hearing at its upper end on which the batten is slidablv mounted. a
\Vith these objects in view my invention consists of the parts and combination of parts as will be hereinafter more fully set forth.
In the drawings:
Figure 1 is an end elevation of the loom with my invention embodied, parts being shown in section, and partsshown in dotted lines. t
Figure 2 is a front detail elevatirlin of one end of the loom, parts being omitted.
Figure 3 is a detail elevation of part of the loonra Figures 1 and 5 show the invention embodied in a double deck lOOID.
As will be seen from description herein, due to the rigid elements connecting' the shuttle motion lever and the batten by rigid element to the power, all operating parts work in contant relation to the looin frame and do not in any way swing with the batten.
The frame of the machine is provided with suitable bearings 15 in which is mounted a shaft 1 1 on which shaft the shuttle motion lever is journalled at lower end, The shuttle motion lever, according to my in vention, as illustrated herein, is composed of two arms 13 which are connected together by 1927 Serial No. 207,176.
means of the pin 13*, which pin is keyed by means of the key 13% The upper ends 13 of the lever 3 are spread out to form yoke ends forthe lever, which yoke endslare connected by means of the shaft 18 suit-ably se cured thereto.
A suitable casting 12 is revolublyniounted on the pin 13" to which is secured one endof the rod 11, the other endof the rod being connected to a casting 11, which casting inturn revolubly inountedon the pin 9 secured to the disc 10, which disc is mounted on the shaft 8. v
The means for Operating the shuttle motion lever starts with alrecccntrically mounted" gear 1 on the crank shaft 2 of the loom. This gears into tl1ee1lipticalgear 3,1'unning at half the speed of the gear 1. Thorns-art? through the shaftkl drives a Fair ofmitre goal-s 5, thence through the siaft 6, to an- A other pair'of niitro gears 7, and thencethrough shaft 8, to the disc 10, which through cranklpin 9 and the rod 11 connects positivelv ancldirectly to the shuttlemotion lever. Referring now to the forked ends 13 of the shuttle motion lever, it will be seenthat I have mounted thereon across head 20 Which provided with an elongated vertically disposed slot 29 in which the rectangular rod 18 is "positionethlthe head 20 being slidably,
mounted on the rod '18. This head 20His slidably mounted on the Jrodsfll, whichrods extend at right angles to the rod 18 of the sluittle motion lever as moreclearly shown in Figure 2. Theserods 21 are connected to the batten 22 by ineansof the brackets 23 and 24. The bracket 24 is dropped down at the end of the batten to permit of ready remoral of the rack bar 25' for repairs. To remove the rack bar 25am nut 26 is removed, whercup on the bracket 27, which i is ,1 attached by screws, and the like,28, totherack bar 25, and the rackbarare free to be removed from the loom out frointhe end of thebatten. a
The slide or cross-head 20, as above related, provided with an elongated slot 29 in which the rod 18 is free to reciprocate to slide to accommodate the swinging'niiotion of the shuttle niot kin lever 13. The batten 22, car-j ried by the or head 21), in thenroccss of weaving, stings backward and forward in.

any loom; in the baclnvard position the warps being open to ofi er a passage for the shuttle, the batten thcncoming forward to beat up the filling. By means of the slot 29 in the cross-head 20 and the hearings in the upper ends of the shuttle motion lever, the shuttle motion lever is available to operate in any position of the batten being always positively driven and. under control of the operating mechanism so that no bumpers are required. In this connection it will be recalled that bumpers are required for the shuttle motion 80 is a supporting bracket.
The cross-head 20 is connected to a crank 33 011 the shaft 2 by means of the rod or pitinan 3.1, whereby the cross-head 20 and the hattenare positively driven by rigid member, such as the bar or pitman 31.
One great advantage oil this shuttle motion is that due to its constant positive control and easy motion in starting and stopping the shuttles, all rack breakage due to the shock,
' which is daily experience in the looms now in use, has been done away with.
In usual commercial practice the shuttle motion has beenlargely the limiting element in speed at which looms can be practical ly operated, lViththi u ew shuttle motion the limit of speed; as far as the particular part of the mechanism is cducerned, has been entirely eliminated, besides which another very desirable result of my invention is that I am enabled to materially reduce the noise in the 100111 room. i
As has been stated, the main object of this in Figures 4 and 5.
In Figure at the rods Ci correspond with the rods 21 in the other figures. Dare the batten rack bars. These batten rack bars are connected by the cross-head or slide E, which slides on the rods C. The cross-head E is provided with an elongated slot F, which corresponds with the elongated slot 29 in the other, figures of the drawing. The operation in this embodiment has been described in connection with Figures 1., 2 and 3.
In the embodiment shown in Figure 5 the batten bars are designated by the reference between the said leve an letter D, while the cross-head designated by the reference letter G. In this iiustance the cross-head G comprises two mcmljiers which are connected together by a bar K. on which is mounted the knuckle I said knuckle being! tree to slide vertically on the bar K, This lmuchie IJ is provided with an aperture h ll through which a rod corresponding to the rod 18 {Figure 1) is adapted to more.
These embialimcnts shown in l igr es t and 5 with the dos i on just given will be sulticient for thew llcd in the art to uinlcrstand the same.
