SAMUEL LUTZ, oF MARIETTA, ILLINOIS;

TENSION DEVICE FOR FENCE-MACHINES.

SPECIFICATION forming part of Letters Patent No. 436,006, dated September 9, 1890.

Application filed March 29, 1890 Serial No, 345,901. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL LUTZ, a citizen of the United States, residing at Marietta, in the county of Fulton and Stateof Illinois, have invented certain new and useful Improvements in Tension Devices for Fence-Machilies; and I do 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, reference being had to the accompanyin g drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention aims to provide a simple and efcient tension device for machines for wiring wood fences.

In the drawings, Figure 1 is a top plan view, parts being broken away, of a machine embodying my invention. Fig. 2 is a side view, the tension -bars and guide -rollers being shown in cross-section. Fig. 3 is a detail front View of the tension-bars on the line x 0c of Fig. l.

The frame for supporting the operating parts is composed of the corner-posts A, the top and bottom sills B and C, and suitable cross-bars D.

E and F are two cross-beams to receive the ends of the twisters j ournaled therein. There will be as many of these twisters as there are cables of wire in the fencing, two being shown to simplify matters. These twisters may be of any well-known construction, but it is preferred to have them composed of a short-length tube G, which is closed at each end by disks H, which have notches in their edges diametrically opposite to each other for the passage of the wires which comprise the cables. Midway of their ends these tubes G are provided with sprocket or toothed rims I, by means of which the twisters are geared together, being operated from the hand-wheel I', which is journaled on a stud on the sideV of the standard J. This hand wheel has spurs around it-s periphery, and a sprocketchain K passes around this wheel and over the toothed or sprocket rims of the twisters, transmitting motion from said hand-wheel to the twisters. The cable support and picket holder is located immediately in front of the twisting mechanism and comprises the rockshaft L, journaled at its ends in the top side beams of the frame. The plates M are secured to the rock-shaft L and project therefrom at right angles. The treadle N is connected by a strap n with the rock-shaft, the upper end of the strap passing nearly around the shaft, so as to effect a turning of the same when the treadle is pressed upon.

The reel on which the completed fencing is Wound is a shaft O, having journals at or near its ends, by which it is j onrnaled in the hinged boxes I on the top side beams or extensions C thereof. One end of the shaft O is adapted to receive the hand ratchet-wheel Q, by means of which the said shaft is twisted to wind up the fencing thereon. The pawl q is provided to hold the shaft from turningback by engagement with the said ratchet-wheel.

The tension device is located lat the rear end of the frame, or that opposite the reel, and -is composed of two bars R and R, which are held together by a bolt, or more than one, if desired. In the rear of the tension-barsR and R are two rollers S andT to guide the wires between the bars R and R. The spools of wire U are journaled on the corner-posts or other suitable portion of the frame. The guide rollers S and T are arranged upon dierent vertical and horizontal planes, and the tension-bars are on a higher plane than the roller S and between said roller andthe twisters. Y

The operation of the machine is as follows: The wires Y from the spools U pass over the roller T, under the roller S, between the tension-bars R and R', and through the twisting devices G, the ends being secured to the reel. The picket is slipped endwise between the wires composing the cables, and is held in place by the plates M on the rock-shaf t,which are caused to press against the said picket by bearing down on the treadle N. The handwheel I is operated to turn the twister-s and twist togetherthe wires between the picket and the twisters. After a picket is secured between the strands of the cable the reel is turned, by means of the hand ratchet-wheel Q, to wind the fencing thereon and draw the wires forward to make way for another picket, which is secured between the wires, as hereinbefore described.
