WILLIAM M. AUGUSTINE, OF -SOUTH BEND, INDIANA.

WIRE-TWISTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 369,765, dated September 13, 1887.

Application tiled April 13, 1887. Scl-inl No. 234,589. (No modeLl To all whom, it may concern,.-

Be it known that I,W1LL1AM M. AUGUsrINE, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Wire-Twisting Machines for Constructing Combined Wire and Iicket Fences; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in machines for twisting the longitudinal supporting-wires around the pickets of a combined wire and picket fence; and it consists in eertain novelty in the construction and arrange-v ment of the various parts of the same, all of which I will now proceed to point out and describe, reference being had to the accompanying drawings, in which- Figure l is a perspective of my said invention, showing the same in use, a section of fence being shown in process of construction.

Fig. 2 is a vertical central section of the same, A

and Figs. 3 and 4 are details showing various parts of my invention.

Referring to the drawings, A represents a suitable standard or board forming the frame of the machine, on which the twisting mechanism is mounted. Said standard is provided on its rear side with a handle, A', for moving the same.

ct are a series of apertures in the center of said standard, arranged in a vertical line one above the other.

B B are similarly-formed reciprocating rackbars mounted in suitable guides, a, on the front of the standard and located on either side of theapertures a.

C is an operating-lever pivoted at its center on a bolt, c, secured in the upper end of the standard, said bolt forming the fulcrum ofthe lever. The lever C is connected with the rackbars by arms c c', the upper ends of said arms being pivoted to the lever and their lower ends to the upper ends of the rack-bars. By means of this lever the rack-bars are reciprocated, for a purpose hereinafter set forth.

a2 a2 are two series of holes arrangedon each side of the standard A immediately above the rack-bars and in a vertical line with said rack-bars. Said holes are provided with adjustable stop-pins c a3, which engage with the upper ends of the rack-bars and limittbe movement ofthe same.

D are suitable twister heads, preferably conical in form, as shown, and having formed on their smaller ends and integral therewith pinions D and extensions D2, of less diameter than the pinions. Between the conical portion of eachtwister-head and its pinion is formed an annular groove, d. The pinions D of the twister-heads are mounted between and engage with the rack-bars B B, and the eX- tensions D'z extend through the apertures a, but do not have a bearing in said apertures. Said twisterheads are held in position by flanges b b on either side ot' the rack-bars, which flanges engage with the grooves d, and the sides of the pinions approximate to the standard. In each twister-head are suitable wire receiving apertures, E E, having openings e e in the larger end of the twister-head, arranged diametrically opposite each other. Said apertures E E converge to a common aperture, E, which extends through the pinion and extension and has an opening, e', in said extension.

Any desired number of twister-heads may be used, according to the height of the fence to be constructed and the distance apart it is desired to place the longitudinal supportingwires.

In Fig. l, F represents a section of fence in process of construction. F are the pickets, and f the pairs of longitudinal supportingwires.

In operation each pair of longitudinal wires are first threaded through the apertures in thetwister-heads. Thewiresarethenstretched from end to end and secured to posts or to any other suitable device for holding the same. The machine being in the position shown in Fig. I, a picket is inserted between each pair ot' wires. Then by operating the lever the rack-bars arereciprocated, one going up while the other goes down, thus turning the twisterheads and twisting the wires. Taking hold of the handle A', the machine is moved a suitable distance, another picket is inserted, and the operation repeated, and so on until the section of fence is completed. As each section is completed, the wires are secured to suitable posts. When the ends of the wires have been reached, they are released from the post or other device from which they were stretched and the machine removed from said wires.

By means of the stop-pins a3 as the amount of twist given the wires may be regulated, said pi-ns being adjusted to limit the move ment of the rack-bars so as to turn the twister half around, once around, once and a half or twice around, and thus twist the wires as much as desired.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. In the herein-described wire-twisting machine, a standard provided with apertures arranged one above the other in a vertical line, two reciprocating rack-bars mounted on the standard on either side of the apertures, and an operating-lever connected with the rackbars, in combination with suitable twisterheads extending through the apertn res in the standard and having pinions mounted between and engaging With the rack-bars, and provided with wire-receiving apertures having openings diametrically opposite each other in one end of the twister-heads and converging to a common aperture having an opening in the opposite ends of said twister-heads,all constructed, arranged, and operating substantially as set fvorth. 1

2. In the herein described Wire twisting machine, a standard provided With apertures arranged one above the other in a vertical line, two reciprocating rack-bars mounted on the standard on either side of the apertures and provided with projecting flanges on either side of the racks, an operating lever connected with said rack-bars, and adjustable stop-pins on said standard for limiting the movement of said rack-bars, in combination with suitable twister-heads extending through the apertures in the standard and provided With pinions mounted between and engaging with the rackbars and held in place by the iianges of said rack-bars, said pinions being provided with Wire-receiving apertures having openings diametrioally opposite each other in one end of the twister-heads and converging to a common aperture having an opening in the opposite end of said twister-heads, all constructed, arranged, and operating substantially as shown and described.

3. In a Wire-twisting machine, the standard A, having the apertures a, arranged one above the other in a vertical line, the reciprocating rackbars B B, suitably mounted on the standard on each side of the apertures a, and the operating-lever C, connected with the rackbars B B, in combination with the twisterheads D, having the pinions D mounted between and engaging with the rack-bars, and the extensions D2, extending through the apertures a, said twister-heads being provided with wire-receiving apertures E. E, having openings e e in one end of the twister-heads and converging toacommon aperture, E', having an opening, e', in the end of the extension D2, all constructed, arranged, and operating substantially as shown and described.

4. In aWire-twisting machine, the standard A, provided with apertures a, arranged one above the other in a vertical line, the reciprocating rack-barsB B, suitably mounted on the standard and having projecting anges b b, t'he operating lever G, connected with the rackbars, and the adjustable stop-'pins a a3, for limiting the movement of the rack-bars, in combination with thetWister-heads D, having the wirereceiving apertures E E, converging to a common aperture, E, said apertures extending through the twister-heads and provided with the annular grooves d, pinions D', and extensions D2, said pinions being mounted between and engaging with the raGkbarSand'heId in place by the flangesb b of said rack-bars, and said extensions D? extending through the apertures a in the standard. all constructed, ar-

ranged, and operating substantially as shown
