MACHINE FOR FORMING WIRE LOOPS.

SPEGIFICATION forming part of Letters Patent No. 518,381, dated April 17, 1894:.

Application filed August 23, 1893. Serial No. 483,811. (No modeli) To all whom it may concern:

Be it known that we, DAVID WHITE and ALEXANDER F. LAGERWALL, both residing in the city, county, and State of New York, have invented an Improved Machinefor Forming Wire Loops, of which the following is a specification.

Our present invention relates to machines for forming wire loops and especially wire loops for wiring corks in bottles and the like, and has for its .object to produce an improved means for rapidly forming and cutting off wire loops from wire fed into the machine, and consists in the mechanism as illustrated and set forth herein, and which willbe specifically pointed out in the claims. We attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side view of our improved machine. Fig. 2 is a front view of the same. Fig. 3 is a top view thereof. Figs. 4 and 5 are views showing the knife in two operating positions, the section through the table being taken on line 4--5 of Figs. l and-3. Figs. 6 and 7 are detail views in top view and in section of difierent forms of head on which the loop is formed. 1

A designates a spindle supported on standards b b on the table B. Chains or cords c and d are connected at one end thereof to the spindle and wound upon the spindle in reverse directions. The free end of chain (1 is connected to the treadle C. Thefree end of the chain c is connected toone end of a restoring spring S suitably attached at its other end to the frame of the table. For this use we have found that a triangular chain will lie evenly on the spindle and is particularly.

suited for this purpose. The spindle terminates at one end in a hook f upon which is fitted a; removable sleeve or head g, upon which the loop is formed, or else the loop may be formed directly upon the hook. Mounted upon the table in a slot 71. in line with thein brackets Z on the under side of the table is a. rectangular frame m. To the'rod 91 forming part of the frame is pivoted one end ofa link 0, the other end of which is pivoted to the pivoted knife 10. The jaws q, r, co-operate with the knife to cut the wire. The head 5 carrying the knife 10 and jaws q, 1', is mounted in a slot 25 in the table extending parallel with the axis of the spindle A. The head 8 is movable in the slot and maybe secured in its adjusted position by the wing-nut u. The link 0 may be moved along the rod n to follow the movement of the head 8. To allow for such movement the table is slotted as at 'v. The frame which is connected with and which actuates the knife is itself actuated by a pitman D connected to the treadle, orwe may operate the pitman from the treadle in any other suitable manner.

end of the wire is led from the reel w on the bracket 00 attached to the. table, and passed around the end of the hook and brought back to the head 8 which thereby forms a guide to the length of the ends of the loop. The wire leading from the reelto the hook is inserted between the jaws q, r, of the double acting knife. The pin is on the head 2 passes between the two parallel strands of the wire as shown in the Fig. 3. The parts are now in the position of Figs. 1 and 3 pressure upon the treadle will unwind the chain 01 and rotate the spindle and hook, and by the co-operation of the pin is will form a loop Z in the wire and by means of pitman D operate the knife 10 with the jaw q to out the wire. The treadle is now in its lowest position, but the diameter of the spindle is so proportioned to the stroke of the treadle that the end of the hook f is again vertical. The knife is in the position shown in Fig. 5. The loop formed is g The treadle is cush ioned by the adjustable threaded rod a in a bracket 6' with a jam-nut d for adjusting now removed from the hook and the end of the wire on the coil led between the jaws of the double acting knife, around the hook, and pin, and the end brought up to the head 5 as before. Upon releasing the pressure upon the treadle the restoring spring S will rotate the spindle, by means of chain c, in the reverse direction and restore the parts to their initial position. The rotation of the spindle will form a loop as before and the knife 19 will co-operate with the jaw r to cut the wire.

To form loops of various styles and sizes we use removable sleeves or heads g of vari ous shapes and sizes upon the hook f, and vary the location of the heads 71 and s carrying the pin is and the double acting knife 1).

We do not limit ourselves to the precise construction shown, as we may variously connect the treadle with the spindle, or employ power to run the machine, without departing from the spirit of our invention. 7

What we claim, and desire to secure by Letters Patent, is-- 1. In a machine for forming wire loops, he combination with a spindle provided witha hook for engaging the wire, together with a pin co-operating with the hookto form a loop,

of a treadle and connected mechanism for rotating the spindle in one direction, and a restoring spring connected with the spindle for rotating it in a reverse direction, substantially as described.

2. Ina machine for forming wire loops, the combination with a spindle provided with a hook for engaging the wire, together with a pin co-operatin g with the hook to form a loop, of chains reversely'wound upon the spindle and connected respectively to atreadle for rotating the spindle in one direction, and to a restoring spring for rotating it in a reverse direction, substantially as described.

. 3. The combination in a machine for forming wire loops of a hook for engaging the wire, a pin' adjustable to and from the hook,

and cooperating therewith to form a loop, and a knife for cutting the wire independently adjustable to and from the hook, substantially as described.

4. The combination in a machine for forming wire loops of a rotary hook for forming the loop, a treadle and restoring spring for rotating said hook in either direction, and a double acting knife to cut the wire actuated by the treadle in its motion in either direction, substantially as described.
