WILLIAM J. LUTTON, OF PATERSON, NEW JERSEY.

Specification of Letters Patent.

Patented Mar. 7, 1911.

Application filed September 10, 1907. Serial No. 392,107.

To @ZZ whom it may concern:

Be it known that I, WiLLlM/r J. lnrrron, a citizen of the United States, and a resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Looms, of which the following is a specification.

My invention relates to looms and more particularly to the mechanism which coperates with the shuttle at the middle shuttle box on a double loom, and to means for connecting the picker sticks which work in unison. l

In the accompanying drawings, Figure 1 is a view in front elevation of so much of a double loom as will sufiice to show the location and operation of the several parts to which my present invention pertains with respect to the loom as a whole. Fig. 2 is an enlarged partial front elevation at the central portion of the loo-m, Fig. 3 is a vertical section in the plane of the line A-A of Fig. 2, Fig. l is a horizontal section in the plane of the line B-B of Fig. 2, and Fig. 5 is a partial longitudinal vertical section showing the picker retarding mechanism in front elevation.

rllhe loom frame is denoted by 1 and may be of any well known and approved form suitable for the purpose. The central shuttle box `common to the shuttles from the opposite sides of the loom is denoted by 2, the shuttle being arranged to travel along a suitable way 4L in the beam 5. One set of picker sticks for operating the shuttles is denoted by 6, 7 and the set on the opposite side of the loom by S, 9. rlhese picker sticks extend-as usual up into position to operate the shuttle to send it from the side of the loom toward the center and from the center back again to the side of the loom. The picker sticks 6, 7 are connected to move in unison by means of a bent link 10 pivotally secured at the extremity of one arm to a bracket 11 on the main frame, a rod 12 extending from the knuckle or angle of the bent link 10 to the picker stick G and a bar 13 extending from the opposite end of the bent link to the picker stick 7. The connections of the bars 12 and 13 with the bent link 10 are made by means of elongated slots 111, 15, in the link through which connecting bolts 16, 17, extend into the bars 12 an 13 to adjust the icker sticks in the desired relation to the shuttle. In like manner the picker sticks 8, 9 are connected to move in unison by a beni I link 18 in a manner quite similar to that hereinabove described with respect to the picker sticks 6 and 7. The bent link 10 rocks on pivotal pin 19 on the bracket 11 and the bent link 18 similarly rocks on the corresponding bracket on the main frame.

Projecting into the path of the shuttle 3 within the box 2, the box 2 being a `continuation of the raccway along the beam 5, there is a binder 20, the face of the binder 20 toward the shuttle being tapered in opposite directions from the central pin forming the inclined engaging faces 21, 22. At its opposite edge the binder 2O is provided with a recess 23 preferably lined with leather 211. The binder 20 is received in a slot 25 formed in a supporting piece 25: secured to the beam 5 and projecting from its opposite ends at its back, there are flat extensions 26, 27, which. are adapted to enter tapered slots 28, 29, opening from the slot 25 in the supporting piece 25i. The slot 25 is suthcient alone to permit the binder 2() to move endwise to a limited extent a distance suiiicient to place it in position for receiving the shuttle from each of two opposite sides of the loom on one of its oblique faces beyond the center of the loom computing from the side from which the shuttle is advancing toward the central shuttle box. rEhe binder 20 is held in tilting adjustment on a roller S0 mounted on a pin 31 extending laterally from a swinging arm 32 pivotally secured to the bracketarm 33, the latter being attached to the beam 5. A spring keeper 34 attached to the supporting piece 25* at 35, serves to hold the roller 30 wit-hin the recess 23 and gently presses the roller against the leather lining 2li. The roller has a play within the recess 23 and as the arm 32 carrying the roller 30 is swung, the roller will be permitted to move the length of the recess 23 before moving the binder 20 and as it does so, the roller will ride on the spring 34 past the center of the binder 20. The arm 39 will then press in the opposite end of the binder and with it the extension 27, into position to enter the tapered opening 29 toward which the binder is to be thrown for the reception of a shuttle from the opposite direction from that which it last received one. Auxiliary pressure springs 36, 37, are made fast to the beam 5 or to a projection on said beam, and bear against the back of the binder to force it toward the shuttle. Arms 38, 39, xed to the spring-actuated shafts 40, Ilil, press against the back of thc binder (o l'orce it into thc path of the shuttleL 'whenever the shutllc leaves the box, and in entering the box 'the slnittlc is retarded by the spring pres-Lure excl-tod on the binder through these arms, The tension of the anxiliary j )ressure sjjirings 3o, 87, is regulated by means olf screws 42, 48, passing tlnfoogh the spring; and into the beam 5.

A picker ft-{lbuill; up ol leather or other' suitable material is mounted on a rod 45 slzpj'iorlcd at the back o'll thc beam 5 in brackets 46, 4T, in position to be slid along the rod by the picker sticks G and 8 and. projecting into position to engage and move the sliu'ttle along the raceway.

A. lnitter 48 built up o'l' leather or other suitable material is mounted o-n the traine 32 in the path of the picker sticks 6 and 8, so that the picker stick hits thc end of the butter, the latter will be .moved together with the aria 32, bringing the picker stick o a stop and at the saine time swing the arm 232, the latter carrying aloiig with it the binder 20, from one end oit' the slot 25 to the opposite end thereof.

To prevent the picker 44 from rebounding when it has been thrown back with the shuttle by the action of either one of the picker sticks 6 or 8, 1 provide a light retarding spring 49, see Fig. 5, which is arranged to exert light pressure upon the picker 44 as it. nears the limit of its sliding movement in each of two opposite direcltions. The spring 49 is made fast to the rail 54 by means of a screw 51 and the necessary amountof tension is applied to the spring 49 at each of its opposite ends by nieans of adjusting screws 52, 53, set in the rails 54, 55.

ln operation, assuming the. shuttleto be in the position shown in Jfull lines in Fig. 4, the picker stick 8 striking the picker 44, throws the shut-tle back toward the side of the loom, and in so doing the picker is thrown over into the position to be again acted on by the picker stick 6, the picker being retained in its position by the spring 49. The same movement of the picker stick 8 when it strikes the buffer 48, will swing the arm 32, iirst moving the roller 80 to the opposite end of the recess 23 and then, the binder 20 having been tilted into position for its extension to enter the tapered recess 29, the binder will be carried bodily along the recess 25 until its extension 27 occupies the same relative position in the recess 29 that the extension 26 is shown in full lines to occupy in the recess 28. The binder 2O will now be in position to receive a shuttle from the opposite side of the loom and engage the shuttle along its inclined face 22, the face 21 being tilted out of engagement with the shuttle leaving the latter free to .be returned bythe picker stick 6.
