.HEDDL-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent N o. 407,325, dated July 23, 1889. Application filed .Tune 1l, 1888. Serial No. 276,751. (No model.) Patented in France August 26, 1886, No.178,175.

To aZZ whom it may concern.:

Be it known that I, JEAN BNAZET, a citizen of the French Republic, and residing at Rheims, in France, have in vented an Improve` -a machine for making wire heddles, more especially such as is represented in Figure 17 of the drawings; and to this end it consists in the relative arrangement, construction, and combination of parts, as hereinafter described, and pointed out in the claims.

In the drawings, Fig. 1 is a front elevation of the improved machine, certain parts being omitted for clearness of illustration. Fig. 2 is a plan view thereof, showing also the levers D and P and rods C and t t, the parts omitted in Fig. 1. Fig. 3 is a side elevation, and Fig. 4 a plan view, of the central puppet supporting the eye-forming mechanism for the heddle. Figs. 5, 6, and 7 are respectively front elevation, end elevation, and plan View of one of the end-twister blocks. Figs. 8, 9, and 10 are respectively end elevation, front elevation, (partly in section,) and plan view of one of a pair of adjustable puppets placed laterally of the central puppet, and holding each a pin, which limits the twisting of the wire near the loops at the ends of the heddles during the first torsion of the wire. Figs. 1l and 12 are detail views, plan, and section of the rotary central eye forming and twisting block hereinafter referred to as the eye twister-block. Figs, 13 and 14; are respectively plan and sectional views of one of the head-stocks supporting' the spindles on which the end-twister blocks are carried. Fig. 15 illustrates in plan view the position of the wire before twisting. Fig. lshows the same after the first twisting. Fig. 17 shows the same after the second twisting-that is to say, the finished heddle.

A is the base or frame of the machine, of suitable shape for carrying the various parts. On the ends of the base A are the stationary head-stocks or standard-bearings A A for supporting the two spindles A2 A2, which carry the end-twister blocks. The base-plate p h of the twister-block is elbowed in the manner shown and fixed upon the squared part h of the spindle A2 by the nut h2, Figs. 1 and 13. The spindles A2 are movable endwise in their bearings in the head-stocks for a limited distance, their outward throw being limited` by the abutting of the plate 71, against the face of the head-stock.

In a suitable position in the front of the machine is pivoted the hand-lever D, which is connected by the bowed rods tt, respectively, with the spindles A2 A2 in the manner shown, so that the two spindles may be moved inward or toward each other by movement of the lever I). The spindles are held in their extreme outward position by the springs n operating' on levers l, pivoted on lugs Z in the head-stocks and terminating' in forks which butt against lugs or collars m, fixed on the spindle. The tension of the springs n isregulated by the screw-threaded bolts n and thumb-nuts n2, Fig. 1. v

The devices for holding thatpart of the wire which is to be formed into a loop at the end of the heddle, and which I have termed the end twister-block, are shown in Figs. 1 and 2, and on a larger scale in Figs. 5, A6, and 7. The elbowed plates h are flanged in the manner shown at the sides and front to forni a chamber for reception of the wooden blocks r r, having curved faces, as shown, so

that the wire resting thereon may be twisted somewhat more than is necessary at the loop,

and the recoil of the wire after twisting may be compensated so that the loop shall eventually issue quite straight and without twist in itself. The position of the blocks?a r may Vbe exactly regulated by the set-screws fr in the base and sides of the plate 7L. On the front of the plate 7L is the projecting finger j, which extends across the line of the axis of the spindle A2. One of the fingers j carries a slot 1 for receiving the 'end of the wire, Fig. 15. The finger j on the other end twister-block need not be so slit. 'lhe function of the finger j is to shape the inner end of the loop at the end of the heddle, and it is therefore shaped accordingly-that is to say, preferably semicylindrical on its outer face. Behind the IOO blocks fr, also extending athwart the line of the axis of the spindle A2, is the finger 2, fixed in a block adjustable by a set-screw on the plate 7L in any convenient way, so that the distance between the fingers j and 2 may be adjusted according to the length of the loop to be made. The shape of the finger is according to the shape to be given to the end of the loop. The finger carries the projecting part -l to prevent the wire from springing ott' the loop during thetwvisting. To prevent the wire springing oil the finger j, I provide on one side the guard 0, a iixed I )rojecting pin, and on the other side the guard o', the latter being a pin sliding in a socket in the Iingerj, and connected to the spring El', which holds it projected from its socket. The spring 3 extends upward for disengagement by hand when releasing the finished heddle from the machine.

Between the two twister-blocks, at a convenient position on the base of 'the machine, according to the position of the eye in the heddle, is the mechanism for forming the eye. It comprises the rotary twister-block (7, Figs. 1l and l2, formed with the pinion d', and j ournaled in the puppet e inthe axial line of the spindles A2 A2. The block c7 is recessed toward the center, and a corresponding passage-way is cut through the web of the pinion d to admit the wire to lie in the recess. In the recess is iixed the pin g, the shape of which in cross-section corresponds to the shape of the eye to be formed by it. Thepin g may tongue into the block (7 and be fastened by a screw, as shown, in Fig. l2. The bearin in the puppet are also so made as to admit the wire to lie along the axial line of the twisterblock d. To revolve the twister-block, the pinion d gears with a second pinion c, and the latter also with the spur-wheel b on a shaft B, journaled in the base of the machine, and carrying, also, the spur-wheels a a', gearing withpinions (L a on the respective spindles A2 A2. A fly-wheel and crank-handle are provided forrevolving the shaft. By this movement the twister-block d will be revolved in a contrary direction to the end twister-blocks, and the wire stretched between would be uniformly twisted between the eye andthe loops. Since, however, near the eye and the loops it is advisable to twist the wire tighter than elsewhere along the heddle, I have provided devices by which the twisting may be limited to a certain distance each side of the eye and a certain length next to the loops at the end. Having twisted these parts I can then give a slight twist to the rest of the heddle. The said devices comprise pins or fingers to be .set between the wires, and which I term twist-limiting pins, and mechanism for bringing the pins into and out of action. The pins for limiting theloop-twist are carried by the adjustable puppets E E, respectively, Fig. l. The shape and construction of that on the right are shown in Figs. Sto 10 on an enlarged scale. 1J is the base-plate sliding between the guides lp7, fixed by screws adjustably or otherwise to the base A. To the outer end ol' the plate p is hinged the uprightframe 1)', carrying in guides a sliding plate p2, on the upper end of which is fixed the limiting-pin 1' The plate p2 may be lifted or lowered by the lever p, the slot p* of which engages on a gudgeon p5, fastened on said plate p2. On the rear of the plate p is fixed the upright frame p, which carries in a similar manner the pin i', which is raised and lowered in the same way by a lever p, and which serves for fastening the end of the wire of which the heddle is to be made. The frames p and p are connected above by the bent spring p9, so that the frame 2) may give backwardly toward the rigid frame jp" to allow for the pressure of the twisting between the pin /I and the end twister-block. y

The plate p is controlled by the screwthreaded bolt pl, fastened to it and engaging in the nut p, journaled in a bearing p12 on the base A. The puppet E on the left ditl'iers from that on the right just described only in dispensing with the pin t', and consequently with the construction of the frame p and of the lever p9 and means for raising and lowering that pin. The only function of frame p is therefore in this case to support the spring p and bolt p10.

Similarly the eye-twist-limiting pins 7.; 7.1, Figs. 3, el, l5, and lli, are carried on plates 7.1, vertically guided in the sides of the central puppet c, and are controlled by the leversf, the slots 702 of which en gage on gudgeons 7s", fixed to said plates 7.11. The bar C, fixed to the ends of the levers f, extends right and left and passes through slots in the ends of the levers pti 123138, so that all the bins 'zi 'i t 7.17.; may be simultaneously thrown into or out of action by moving the handle l of said bar C.

To prevent the wire springing off the pins 7s 7e, the sliding guard-plates .s are provided, as in Fig. 3, slotted at the ends to embrace the wire. They are connected to the levers f by links s and lever s, so as to be operated with said pins 7."I 7c. Springs u a hold the bar C in the position given to it.

In manufacturing a wire heddle with this machine, the end of the wireis passed through the slotI l in the finger-j, thence along into the eye twister-block around the opposite end twister, back through the eye twister-block around the other end twister, and twisted on the pin i', the pins t' z'l t" 7s 7s having been all raised into action and proj ectingbetween the two strands of the wire, as shown in Fig. l5. One revolution of the shaft A will form the eye-twists a: Vand the loop-twists1/7/, Fig. lo'. The pins 1' t" 7e 7.: are now lowered and another revolut-ion given to the shaftA, by which the main twists are made. By drawing the spindles A2 A2 together by hand-lever l) and loosening the guards ()bydrawingbaek the springs 3 the finished heddle may be removed froln the machine.
