LOOM.

SPECIFICATION forming part of Letters Patent No. 488,569, dated December 27, 1892.

Application filed September 3, 1892- Serial No. 444,938. (No model.)

To all whom it may concern:

Be it known that we, JOSEPH WV. MAURER and ALEXANDER O. IVIAURER, both of the city and county of Philadelphia, State of Pennsyl- Vania, have invented a certain new and useful Improvement in Looms, of which the following is a true and exact description, reference being had to the accompanying drawings, forming part of this specification.

Our invention relates to the construction of looms adapted for weaving fringes, and the object of our invention is to provide a loom of this character so constructed as to weave the fringe rapidly, and adapted to make a large number of fringes at the same time.

The nature of our invention will be best understood as described in connection with the drawings in which it is illustrated, and in which- Figure l is a side elevation of a loom embodying our improvements. Fig. 2 a front elevation of a part of the lay beam shown on an enlarged scale Fig. 3, is a cross-section through the lay beam taken on the line 12 of Fig. 2. Fig. 4 is a plan view showing a portion of the lay beam and of the frame of the machine in front of the lay beam with the attached parts. Fig. 5 is a perspective view of one of the shuttles. Fig. 6 is a view illustrating the construction of a fringe such as our machine is adapted to make. Figs. 7, 8, 9, and 10 are views showing the operative parts of the loom, to which our invention particularly relates, in difierent operative positions, and Fig. 11 a perspective view of the hook and cutter which form a part of our invention.

A is the frame of the loom, the part situated immediately in front of thelay beam being indicated by the letter A.

B indicates the Jacquard apparatus; O the heddles; D warp beams or spools; D D D D D and D guide rods pulleys or rolls for the warp threads and the finished fabric.

D are weighted tension pulleys for preserving a proper tension on the warp threads.

E indicates the warp threads; E that portion of the warps in which the shed is formed by the action of the heddles; E the finished fabric.

F indicates a driving belt acting on a pulley F secured to a shaft F on which is also secured a gear wheel F which engages a gear Gand through it drives the shaft G, to which is or are attached a crank or cranks G To this crank or cranks is connected the rod H, the other end of which is adjustably attached to a projection or projections I secured to the lay beam K.

To the lay beam K are secured the lay swords J which in the construction shown, are pivotally connected at J at the top of the frame. From thelay beam K a series of shuttle guides K extend upwardly with space between them through which pass a series of warps E. The shuttle guides are provided with extensions K formed so as to grasp and hold the shuttle; the lower projection having secured under it on pins K gear wheels K adapted to engage a rack which is formed on the under side of each shuttle, and also to engage a rack K which moves in a groove on the top of the lay beam. In front of each shuttle guide K, the tops of which should be, as shown, united together by a bar U, I secure a finger K the position of the finger being such that it will come between the group of warps on the left-hand side and the hook which will be hereinafter described, the end of the finger being curved substantially as indicated in Fig. 3 for a purpose which will also be hereinafter described.

L is the shuttle which is grooved in its upper and lower faces so as to be engaged by the projecting ends of the projections K on the shuttle guide. The upper groove L is smooth, but the lower one L is formed with a downwardly extending rack which is engaged by the spur pinions K On the front of the shuttle we prefer to form a groove L so as to make the binding screw L, which secures the thread carrier M in place, adj ustable, enabling us to change the position of the thread carrier. The thread carrier consists essentially of two projecting arms M and M which, as shown, are secured to a base plate in turn secured to the front of the shut- IOO to the fabric when the shuttle moves across from left to right. These arms are of course adapted for use with shuttles carrying an ordinary bobbin, but preferably are constructed as shown, with thread holes M M through which one or more weft threads P are led after passing through a guide eye L to which they are led from spools O, of which there are one or more for each shuttle, passing over rods N and through guide eyes N N N to the shuttles.

Q Q are fingers secured to the frame A, one situated between each set of warp threads and the corresponding hook QQ the shank Q of each hook is secured to the frame A so that its hooked end Q will lie in front of each guide K and in such position that when the lay moves forward it will extend in between the arms M M of the shuttle. The back Q of the hook shank (that is, its edge lyingfarthestfrom the set of warps to which it appertains) is preferably formed with a cutting edge which forms one blade of a pair of shears, the other blade R of which, having a cutting edge R, is pivoted on the shank Q at Q, and is provided with a backward extension R which is connected with a spring R which tends'to draw back the blade B, being preferably attached to an arm Q extending out from the hook shank. The arm R is also connected with the lay as by a cord R so that as the lay moves back from frame A, the shear blade R is forced in against the hook shank.

T T 850. indicate the rods secured in each opening between the shuttle guides K.

The operation of our loom is easily followed on the drawings. A set of Warp threads is led from the beams D through each set of reeds T and connected with the heddles C which form the sheds. One or more weft threads P are led from the spoolsO through the guides to each shuttle L, and the loom then started, the heddles of course being connected with and actuated by the jacquard B. Assuming the loom to be in. the position indicated in Fig. 4 with thethread P leading from the shuttle caught under the hook Q the next motion of the loom is the forward motion of the lay beam to the position shown in Fig. 7, the rod T pressing the thread P down into the fabric, and the heddles then moving as usual to bind it in. As the lay moves forward the thread P is caught between the hook and the warp threads by the finger K which presses it in and, by reason of its curvature, (see Figs. 1 and 2) down, causing it to pass beneath the hook shank Q and pushing it along said shank away from the hooked end, the shear blade B being at the time drawn back from the shank by spring R The lay then moves back to the position shown in Fig. 8 and acting on shear blade R by a cord R causes it to move in against the back Q of shank Q and cut away loops of weft thread which have been pushed down the shank to a proper distance.

The shuttles are then actuated from left to right by a convenient mechanism acting on rack K bringing them to the position shown in Fig. 9. The thread P leading from the shuttle is by this movement carried through the shed and over the arms MM in the notches M M of which it lies passing thence back of the finger K through the shed. The lay then again moves forward to the position shown in Fig. 10, the portion of thread P which lies between and over the ends of arms M M being forced by said arms over the hook Q and the portion lying in the shed being forced into the fabric by the reeds. The lay then again moves back and the shuttles are thrown from right to leftbringing the parts to the position shown in Fig. 4. The function of the finger Q is simply to push the cut loops off of the hook shank and the lug indicated at Q simply acts as a stop to limit the movement of the shear arm R. i

We have found it advisable in order to insure that the thread shall fall into the notch M of arm M to provide extending fingers m m from the outside arm M fingers guide and direct the thread into the notch, the lower one 'm keeping it from fallng down beneath the arm, and the upper one As shown these keeping it from curling up over the top'of the arm.
