LOOM.

To all whom 'it may concern:

Be it known that I, WILLIAM J LUTTON, a citizen of the United States, and resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Loom, of which the following is a specification.

My invention relates to looms and more particularly to looms for simultaneously weaving several strips of narrow fabric, rib- Icons, for example, the, object being to provide means for positively moving the shuttles back and forth through the sheds of warp in connection with means for raising and lowering the shuttle boxes.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 is a View of the loom in end elevation, Fig. 2 is a vertical section in the plane of the line A-A of Fig. 1, Fig. 3 is a partial front elevation on an enlarged scale, Fig. 4: is a top plan view of the same, Fig. 5 is a still further enlarged section in the plane of the line BB of Fig. 3, Fig. 6 is a section in the plane of the line C-C of Fig. 5, Fig. 7 is an enlarged partial plan view of the driving mechanism, Fig. 8 is a vertical section taken in the plane of the line DD of Fig. 7, and Fig. 9 is a view in detail showing the yielding stop for insuring an accurate step by step movement of the shuttle operating mechanism.

The loom frame 1, the harness frame 2, superposed thereon, and the bank of beams or rolls for supplying the warp and denoted as a whole by 3, may be of any well known or approved form suitable for the purpose.

The batten, denoted by 4, is supported on rocking arms 5 and 6 from a base rod or bar 7 and a series of shuttle boxes 8, 9, 10, two or more in number, are secured in a frame 11 arranged to rise and fall in the batten 4 by the lifting and lowering of the rods 12 and 13 by means of chains ll, 15, leading to a pattern chain, not shown, and arranged to act upon the rods 12 and 13 in a well known or approved manner to simul taneously raise and lower the series of shuttle boxes in a well known manner as re quired by the pattern chain.

The shuttle boxes 8, 9, 10, etc., each consists of a plurality of compartments arranged in vertical series for containing a vertical series of shuttles, the shuttles in the box 8 being denoted by 16, those in the box Specification of Letters Patent.

9 being denoted by 17 and those in the box 10 being denoted by 18. The several shuttles are quite similar in their construction and the number in vertical series here shown may be increased or diminished at pleasure. The several shuttle compartments in one box have their corresponding compartments in an adjacent box so that a shuttle may be slid back and forth from a compartment in one box to a corresponding compartment in an adjacent box through an intermediate shed of warp, the positions which the sheds of warp occupy being-denoted by the banks of reeds 19, 20, 21.

The shuttles shown on an enlarged scale in Figs. 5 and 6 are denoted by 22. Those which occupy the two upper compartments ,in a box have a toothed rack 23 formed on their upper sides and those which occupy the two lower compartments in a box have a similar rack 24 formed on their lower sides. Toothed pinions 25, 26, are mounted on spindles 27, 28, respectively, the said spindles fixed to the back of the shuttle box with the pinions in position to engage the rack of the shuttle in the upper compartment of the box. In like manner, pinions 29, 30, are mounted on spindles fixed to the back of the shuttle boxin a plane offset from the plane of the pinions 25, 26, and in position to engage the rack in the shuttle in the second compartment of the shuttle box from the top. The pinions 29, 30, intermesh with corresponding pinions 31 on the spindles 27, 28. The pinions 25, 26, and hence the shuttle in the upper compartment of the box are operated by a longitudinally reciprocating rack bar 32 mounted in the batten while the pinions 29 and 30 through the intermediate pinions 31 are operated by a longitudinally reciprocating rack bar 33 located alongside the rack bar 32 and having its line of operating teeth in the same plane with those of the bar 32.

A thin plate bracket 34: is fixed to the top of the rack bar 32 and extends over the top of the bar 33 and thence downwardly to a point about midway of the height of the box frame where it is provided with a rear wardly projecting pin 35, which is engaged by the picker head 36 to operate it and hence the bar 32. In like manner, the rack bar 33 has fixed to its top a thin plate bracket 37 which extends downwardly between the bar 33 and the bracket 34 to a position below the lower end of the bracket 34 where it, in like manner, is provided with a rearwardly projecting pin 38 in position to be engaged by the picker head 36, as clearly shown in Fig. 5. In like manner, but reversed as to direction, the shuttles located in the two lower compartments are operated by means of longitudinally recip rocating rack bars 39, 40, by means of intervening sets of pinions quite similar in their structure and arrangement to that already described with respect to the shuttles in the two upper compartments, the bar 39 being provided with an upwardly extending bracket 41 carrying a pin 42 for engagement with the picker head 36 and the rack bar 40 being provided with an upwardly extending bracket 43 provided with a pin 44 for engaging the picker head 36 to operate the shuttle in the compartment next above the bottom compartment. The picker head 36 is provided with a bifurcated end, the branches 45 and 46 of which, see Fig. 4, are adapted to embrace the opposite sides of some one or another of the pins 35, 38, 42, 44, the particular pin engaged by the branches of the picker head depending upon the position which the shuttle box frame occupies with respect to the batten.

It is to be understood that each shuttle in the consecutive shuttle boxes is provided with a rack and that the box is provided with pinions as already described and further that the longitudinally reciprocating rack bars are of suflicient length to engage the pinions for simultaneously operating the shuttles in the consecutive boxes 8, 9, 10, etc., which comprise the bank.

The picker head slides back and forth on a rod 47 and is operated by means of a link 48 connected with the picker head 36 by a pin 49 and with a vibrating arm 50 by means of a pin 51 which extends through the link 48 and through an elongated slot 52 in the arm 50 for adjusting the length of throw of the picker head and heads of the shuttles. The vibrating arm 50 is fixed to a vertical rock shaft 53, see Fig. 2, which I shaft carries at its lower end an arm 54 connected by a rod 55 with one arm of a bell crank lever 56 pivoted at 56* to the 100111 frame, the opposite arm of said bell crank lever 56 being connected by a rod 57, see Figs. 7 and 8, with a crank pin 58 on a gear wheel 59, the latter being in mesh with a mutilated gear 60 to be operated at regular intervals. The mutilated gear 60 is on a shaft 61 fixed to rotate with a gear 62, the latter in mesh with a gear 63 on a shaft 64 rotated by a large gear wheel 65 in mesh with a driving gear 66, see Fig. 1, on a drive shaft 67.

To insure the accurate throw of the rack bars for operating the shuttles without any error due to lost motion, a yielding stop 68 is provided, pivoted to the loom frame at 69 and having a flattened face 70 which is held yieldingly against a flat sided collar 71 on the shaft 72 of the crank gear 59, by means of a spring 73, see Figs. 8 and 9. The flat sides of the collar 71 are so arranged that they will lie flatly against the flat face of the stop 68 when the operating rod 57 is at the limits of its advance and return strokes so that if there should be any failure on the part of the mutilated gear 60 to rotate the crank gear 59 the complete distance required for a stroke, the pressure of the stop 68 would serve to complete the stroke as well as to prevent an overst-roke and so retain the shuttle in the position where it was intended that it should stop.

In operation, the bank of shuttle boxes 8, 9, 10,'etc., have shuttles located in their corresponding compartments with the exception of one of the compartments in one of the boxes which is vacant in order that the shuttles in that horizontal line of com partments may be simultaneously shifted through the intervening sheds of warp, each into the shuttle box adjacent the shuttle box from which it began its movement. By'raising and lowering the shuttle box frame, the picker head 36 may be caused to engage any one of the four "rack bars to operate any one of the line of shuttles back and forth through the sheds of warp thus producing the desired colors or characters of weave. Furthermore, the crank motion for operating the picker head will cause the shuttles to begin their movement at a moderate speed, to move rapidly during the middle portion of their travel and then to gradually slow as they approach the limit of their movement thereby rendering it feasible to materially increase the number of picks per minute over the number which can be obtained from the ordinary pick motion.

WVhat I claim is 1. In a loom, a plurality of shuttle boxes spaced apart to admit a shed of warp between each consecutive two, each box being provided with a plurality of shuttle compartments, a series of rack bars and pinions for operating the shuttles, a sliding picker head constructed to positively and detachably engage one or another of said rack bars and to move itin each of two opposite directions, means for raising and lowering the shuttle box frame to bring the racks intG position to be engaged by the picker head and means for operating the picker head.

2. In a loom, a plurality of shuttle boxes spaced apart to admit a shed of warp be tween each consecutive two, each box being provided with a plurality of shuttle compartments, a series of rack bars and pinions for operating the shuttles, a sliding picker head constructed to positively and detachably engage one or another of the rack bars to move it in each of two opposite directions, means for raising and lowering the shuttle box frame to bring the racks into position to be engaged by the picker head, a vibrating arm connected with the picker head, a rock shaft for operating the vibrating arm and a crank wheel for operating the rock shaft.

3. In a loom, multi-compartment shuttle boxes spaced apart to admit a shed of Warp between them, shuttles provided with racks and seated in the compartments, rack bars placed side by side and mounted to reciprocate longitudinally, pinions connecting the rack bars with the shuttles, brackets fixed to the rack bars and provided with pins at different heights, means for raising and lowering the shuttle boxes and a picker motion including a slotted picker head adapted to receive one or another of the said pins at pleasure.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence 01": two witnesses, this eighth day of June A. D. 1908.
