1 WlR'E-TYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 546,727, dated September 24, 1895.

Application filed April 28, 189 11 Serial No. 509,356- (No model-l To aZZ whom it may concern Be it known that I, FRANK G. CHAMBERS, of Syracuse, in the county of Onondaga, in the State of New York,have invented new and use ful Improvements in Wire-Tying Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to wire-tying machines and the manufacture of wire gauze and cloth. The strain upon strands is often so great that they break, which necessitates tying 0r splicing of the ends together, and as the value of the gauze depends upon the neatness with which this tie is made, and as the cost depends upon the dispatch with which it is done, my purpose is to produce an inexpensive machine by which the operator easily, quickly, conveniently, and neatly ties the broken ends together; and to that end my invention consists in the several new and novel features and combination of parts, which are hereinafter described, and specifically set forth in the claims hereunto annexed.

It is constructed as follows, reference be ing had to the accompanying drawings, in which- Figure 1 is a side view of the tying-machine complete, ready for use. Fig. 2 is a vertical section on line x x in Fig. 3. Fig. 3 is a vertical section on line y y in Fig. 2, except through the twisting and tension wheels. Figs. 4. and 5 are vertical longitudinal and cross sections, respectively, of the twisting-wheel mounted upon the feed-screw, detached. Figs. 6 and 7 are side and edge views, respectively, of the tension-wheel bracket. Figs. 8 and 9 are side and end views, respectively, of the twistingwheel. Fig. 10 shows views of the various sides of the feed-screw. Fig. 11 is an end View thereof. Fig. 12 is a view of the springs which engage the end of the feed-screw. Fig. 13 shows views of the wire just before and just after tying.

Similar letters of reference indicate corresponding parts.

A is the body or frame of the machine, in which the parts are mounted, and is preferably constructed substantially as shown, having means for securing it to the bench at its lower end and having a central opening a, enlarged at its upper end, as shown at b, and

is provided upon its upper endwith lateral ears 0, having openings d, one of which is threaded, for the purposes hereinafter set forth, and its inner face provided with shoulders e, but one being shown in the drawings.

B is a twisting-wheel having an annular groove fthereimas shown, and having its ends provided with a shoulder g and recessed centrally to receive the feed-screw h, upon which it is rigidly secured so as to rotate said screw, one end of saidscrew being threaded and adapted to engage with the thread upon the aperture d, as above set forth. The twisting-wheel B is also radially slotted, as shown at 11, for the purposes hereinafter set forth. The feed-screw h is also slotted, as shown at j, and secured within the twisting-wheel, so as to have the slotways concentric to each other, and provided with means for securing them rigidly together, as shown in Figs. 4 and 5, although I do not limit myself to this method of securing the parts together, as it will be evident that any other well-known method may be employed. 'As here shown, the longitudinally slotted or grooved shaft 77. is secured in position in the wheel by the screw f, which passes through the side of the wheel, and which screw has its inner slotted end to pass through an opening in the side of the shaft, as shown. By having the end of the screw pass through or into the shaft all possibility of the shaft turning in the wheel is avoided, and the groove in the shaft is kept in line with the groove in the wheel. The grooved inner end of the screw of course stands in a line with the grooves of the shaft and wheel, and this grooved end of the screw serves to help hold the overlapping ends of the wires and cause them to twist together when the wheel and shaft are caused to revolve in either direction.

O is a bracket or frame mounted yieldingly and held in place in any ordinary manner between the ears 0, as shown in the drawings,

adapted to rest on aspring 70, which in turn strapsprings secured upon the exterior faces of the ears and adapted to engage with the ends of the feed-screw h, and having V-shaped slotways 0 therein for the purpose of holding the strands of wire, preparatory to their being twisted about each other, as shown in Fig. 13. D is a string or cord passing through the opening 19, formed by the grooves within the twisting-wheel B and the tension-wheel m, I0 and by which the twisting-wheel B is rotated. In Fig. 3 of the drawings dotted lines extend outward from the ends of the feed-screw. These are the wires which lap each other within the annular grooves of the twistingwheel,which are twisted or tied together. It will be observed that when the strands of wire break they are first lapped, as shown in Fig. 13. They are then passed down through the groove t' and slot j in the twisting-wheel and feed-screw, the ends resting, as shown in dotted lines in Fig. 3, in grooves of the strapsprings. The springs it serve to hold the ends of the wires, so that they cannot turn while their ends are being twisted together. By pulling the cord D forward or backward the wheel 13 is caused to revolve and the overlapping ends of the wires are twisted together, forming a splice, as shown in Fig. 13. As the shaft 71, is screw-threaded at one end and re- 0 volves with the wheel, the screw and shaft are caused to move endwise until the shoulder on the wheel strikes against the corresponding shoulder on the frame, when the retary motion of wheel and shaft is brought to a stop and the wires are removed. Other wires are then inserted and the wheel and shaft are revolved in the opposite direction.

\Vhat I claim is 1. A tying machine comprising a body, a 40 radially slotted twisting wheel, secured on a grooved or slotted feed screw mounted in said body, and means for actuating said feed screw laterally.

2. A tying machine comprising a body, a 5 radially slotted twisting wheel secured on a grooved or slotted feed screw mounted in said body, means for actuating said feed screw laterally, and a tension wheel vertically mounted and adjacent to said twisting wheel, and intermediate means for operating the twisting wheel, as set forth.

3. A tying machine, comprising a body, a radially slotted twisting wheel mounted therein having shoulders upon its ends, shoulders or lugs upon the inner face of the body with which the aforesaid shoulders are adapted to engage for the purpose of stopping the twisting wheel, and means for rotating said wheel, substantially as described for the purposes set forth.

4. The frame, an adjusting screw extending up through it, a' spring, the supporting frame 0 placed upon the top of the spring, and a tension roller loosely journaled in the supporting frame, combined with the slotted twisting wheel, and an operating cord for causing the wheel to revolve, substantially as shown.

5. The frame A, pronged at its upper ends, the slotted springs applied to opposite sides, the slotted journal screw threaded at one end only, the slotted twisting wheel placed upon the journal, a set screw, slotted at its inner end and which has its slotted end to extend up into the slotted journal, and means for causing the twisting wheel to revolve, substantially as described.

6. The frame A, provided with prongs at its upper ends, and shoulders formed on the inner sides of the prongs, slotted springs applied to the outer sides of the prongs for holding the ends of the wires to be twisted, and a slotted journal screw threaded at one end, and which is made to move back and forth through the prongs, combined with the twisting slotted wheel secured to the journal and also provided with shoulders on its ends, a tension wheel, and means for causing the twisting wheel to revolve, substantially as set forth.

In witness whereof I have hereunto set my hand this 20th day of April, 189%.

FRANK G. CHAMBERS.
