MACHINE FOR MAKING MIDDLE EYES OF HEDDLES.

SPECIFICATION forming part of Letters Patent No. 630,874, dated August 15, 1899.

Application filed August 11, 1896. Serial No. 602.404. (No model.)

To all whom it may concern: l and 2, through which the reciprocating draft Be it known that I, MAX ALFRED FICKER, bars t" 1' work, suitable means being provided a subject of the King of Saxony, residing at at their lower ends, as will be readily under- Chemnitz, Saxony, Germany, have invented stood, for operating said bars. The bars are 55 5 certain new and useful Improvements in Marespectively connected at their upper ends chines for Making Middle Eyes of Heddles, with two-armed levers h 7L2, whereby the le- (in respect whereof I have obtained Letters vers c c g g pertaining to the mechanism Patent in Germany, No. 91,016, dated March for holding the wires, are operated. 21, 1895, andin Great Britain, No. 7,651, dated The wire is held on each side of the eye by 60* 10 April 16, 1895,) of which the following is a means of athree-part clip or holder, the same specification. being arranged and operated as hereinafter This invention relates to the production of described. Each clip is a counterpart of the the middle eyes of heddl es composed of two other, so that a description of the parts of wires soldered together; and it consists in imthe one is applicable to the other. On the 65 proved means for holding and adjusting the frame G is secured an L-shaped bracket B, said wires during the splitting and twisting whereof the upright portion is formed with a operations, whereby the formation of the said correspondinglyextending dovetail projeceyes is effected in a more certain and uniform tion, on which a correspondingly-formed slidmanner. ing plate d works, the latter being main- 7o In the accompanying drawings, Figure 1 tained in position by the screwor pin C in the represents in side elevation aheddle-forming arm D and being automatically adjustable machine embodying the present improvealong the dovetail slide by means of the coilments.

This 75 plan, respectively, of the mechanism emspring, while serving to efiect the lateral pioyed in forming the middle eye, the same movement of the sliding plate, maintains a being shown in connection with the apparatension on the wire. On the face of the plate tus for making the end loops. Figs. 4E and 4 d is secured a carrier E, whereof the outer are views in plan of the mechanism employed end is provided with a shaft having mounted 8o in making the end loops, the formershowing therein in any suitable manner another shaft the position of the parts immediately after E Mounted on said shaft is acoil-springf, the end of doublewire has been turned back whereof one end is secured to the carrier, to form the loop and the latter the position while the other end is extendeda certain disof the parts when the operation of twisting tanoe toward the center of the machine and 85 has been accomplished and the wire is free is then bent at right angles.

Figs. 7 and 8 represent in side view ver E is secured the part'a pertaining to the and horizontal section, respectively, the declip or holder for the wire. The part a of the vice forsplitting and twisting the wire to form clip orholder is carried at the upper extremity 5 the middle eye. Figs. 9, 10, and 11 illustrate of the lever g or 9 as the case may be. Each various positions of the holding or clipping of the said levers is mounted on a fulcrummechanism during the manipulation of the pin y or 1 and is furnished at its lower exwire. tremity with an incline n or W, a spring '1."

The apparatus is mounted upon a suitable or o by pressing against the lower extremity, I03 frame G. Upon each side of the vertical cenpreserving the severance of the parts a and ter line of this frame are secured the guides a of the holder.

The two-armed levers 71/ h2 are each connected to the upper end of its respective d raftbar "L" or 2' and pivotally mounted on a pin 2 or .2 carried by the plate 61, the outer extremity 71. working against the curved plate or spring q, while the inner extremity works against the inclined portion 02 or n of the lever g or g Between the holding devices is placed the splitting and twisting mechanism,

the same comprising a stationary casing K,-

in which is mounted adisk Z, provided with an L-shaped or right-angled opening Z", in the central portion .of which is a reciprocating splitting-pin s. This pin is carried in a sliding block 0, which is connected with the extremity p of the lever 19 by means of a pin 0. The lever 10 is fulcrumed at p and is vibrated by means of a cam 02 on the main shaft, Fig. 1, the cam being so formed as to cause the leverp to dwell during the-rotationot' the disk 1, and thereby maintain the pin 3 in its raised position during the formation of the eye. The disk Z is provided with teeth 1-, which form a circular rack for engaging with the teeth of the quadrant t, mounted on the main shaft of the machine.

The mechanism for forming the end loops, Fig. 4, and for feeding the wire, Fig. 4", are situated on either side ofthe middle-eye forming mechanism.

F is a shaft having a cranked extremity.

M is an arm hinged to the plate L, secured to the frame G, a lug M being provided at the outer end of said arm M.

N is a spring secured to the plate L and adapted to bear against the arm M. The wire \V is passed through an opening provided in the plate L.

The operation of the improved mechanism in forming a middle eye is as follows: The requisite length of double soldered wire having been fed into the machine the wire is held in the inner portion of the angular opening Z of the wheel Z by means of the threepart clips or holders, Figs. 9, 10, and 11, the wire being thereby maintained in a horizontal or flat position. The splitting-pin s is then operated, the pin rising and entering between the wires, whereupon the wheel Z, through the medium of the quadrant t, is rotated, with the result that the necessary twists are made at each end, of the eye. The slight shortening of the length of the heddle incidental to the twisting operation is compensated for by the springs m 072 pertaining to the clips or holders.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The herein-described means for forming the middle eye in soldereddouble-wire heddles, the same comprising a pair of three part clips or clamps for holding the wire in a flat position, a splitting and twisting device consisting of a casing fitted with a rotating body adapted to receive the wire and furnish ed with a reciprocating splitting-pin,'and

3. For forming the middle eye of soldered double-wire heddles, a frame having draftbars mounted. in guides thereon, two-armed levers h, h2 pivotally mounted at the upper end of said draft-bars, and fulcrumed in slid-' ing plates carried on brackets secured to said frame, two-armed levers e, 6 g, g mounted on said plates, springs adapted to engage each of said levers, each of which carries a part of the clamping or holding device while the plate carries the other part; a casing being mounted between the clamps and fitted with a toothed wheel provided with an angular opening, a lever pivotally mounted on the casing and having at its inner end-a pin' adapted to form. said eye, all constructed and operating substantially as described.

4. For forming the middle eye of soldered double-wire heddles, a frame having guides secured thereon, draft-bars working in said guides, double-armed levers secured to the upper end of said draft-bars, plates having clamps fastened at their upper extremities,

carriers secured to said plates and having 1evers fastened thereon, steel dies on said levers and springs adapted to engage said levers, and a holding-casing having mounted therein a toothed wheel, a lever pivotally mounted on said casing and connected at its inner end with a slide fitted with a pin, the slide and pin being revoluble with said toothed wheel, substantially as described.

In testimony whereof. I affix my signature in presence of two witnesses.

MAX ALFRED FICKER.
