FENCEJl/IAKENG MACHINE.

SPECIFICATION forming part of Letters Patent No. 314:,61-6, dated March 31, 1885.

Application filed August 15, 1884. (N model.)

To aZZ whom it may concern.-

Be it known that I, NELSON P. BRADIsH, of Jerseyville, in the county of Jersey and State of Illinois, have invented a new and Improved Fence-Making Machine; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in fence-making machines of that class employed in the manufacture of fencing which consists of wooden or other palings united by wires twisted together so as to form a continuous I 5 web.

One of the objects of my invention is to provide means for operating the wire-twisters by a reciprocating hand motion.

A still further object of my invention is an improved means for regulating the tension put upon the wire as it is delivered from the coil to the twister.

With these ends in view my invention consists in certain details of construction and com- 2 5 binations of parts, hereinafter fully described,

and pointed out in the claims.

In the drawings, Figure 1 is a plan view of that part of the machine containingmy improvement, and Fig. 2 is a rear elevational 0 view of the same.

In both figures, A represents the frame upon which is supported the operative part of the machine. I) b, &c., are wire-twisters, adapted to revolve in bearings c, and actuated by small 3 5 gear-wheels d, which engage with a toothed rack, e, which is also provided with teeth upon its rear vertical side, adapted to engage with teeth upon the face of a segmental wheel, f, provided with a long hand-lever, 9, said segmental wheel being fulcrumed upon a stud, h, secured to the top side of a cross-bar, t. At the lower part of the rear of the frame are two crossbars, J, which support vertical bars It, between which are journaled arbors Z, upon which 4.5 are mounted expanding reels m, one of which is shown in section taken in the line of its axis, Fig. 1, said reels being adapted to carry the coils of wire, as exhibited in the drawings. By reference to Fig. 1, in wliich two of the vertical bars k are shown in section taken in the line of the axes of the reel-arbors Z, it will be observed that said reel-arbors are provided with conical ends a, adapted to revolve in similarly formed hearings in the vertical bars k. It will also be further noticed that all the sup- 5 5 porting-bars it, except the two outside ones, are movable about the pivots o in the plane of the axes of the reel-arbors, and are adjustable in said plane by thumb-screws p, so as to impinge upon the ends of the reelarbors 6:) with such force as to resist their rotation to such a degree as will produce the requisite tension upon the wire between the reels and the twisters. It will be still further noticed that the rear upper part of the frame A is pro vided with a cross-bar, q, adapted to support the free ends of the movable bars it against the tensile strain of the wire, and also that the rack e is retained in position by small flange rollers r.

The details of my device being as above described, its operation is as follows: The coils of wire being mounted upon the reels, as shown in the drawings, and the ends of the wires passed through the holes in the twisters to the palings, and the thumb-screws tightened up so as to afford such resistance to the rotation of the reel-arbors as to put the requisite tension upon the wire, the hand-lever g is operated as indicated by the arrows'in Fig. 1, each stroke giving a similar and simultaneous rotary motion to all the twister-s, the number of turns depending upon the length of the stroke, which is of course controlled by the operator. Now, it will be observed that as the reels are separate from the twisters the rotation of the latter will cause a twist between them and. the reels; but as two revolutions of the twisters are the most ever required, when the hand-1ever is at one extremity of its stroke. the wires are so threaded through the eyes of the twisters that there is a twist of one turn between the twister and the coil, and that twist is in the opposite direction to that in which the twister is about to be rotated. Consequently the first revolution of the twister removes the twist between itself and the coil, and the second re- 7 news it in the opposite direction, so that while a twist of two turns may be given to the wires between thc palings there can never be a twist of more thanone turn between the twister and the coil, which, owing to the distance between the latter and the twister, is in no degree detrim'ental.

' Having fully described my invention, whatl claim as new, and desire to secure by Letters Patent, is

1. In a fence-making machine, the combination, with the wire-twisters I), provided with gear-wheels d, of the actuating mechanism described, consisting, essentially, of a toothed rack, e, and segmental gear f, provided with a hand-lever, g, allof said parts constructed, cornbined,and adapted to operate substantially as andfor the purpose set forth.

2. In a fence-making machine, the combination, with the reels m, secured upon arbors Z, of the conical ends at and supporting-bars k, provided with sockets adapted to receive the conical ends of the arbors Z, and pivotally secured at their lower ends to the frame of the machine so as to vibrate in aplane coincident with the axes of the reel-arbors, and controlled as to the force with which they impinge upon the ends of said arbors by thumb-screws 19, substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 31st day of 0 Witn esses A. NEWTON, O. HAMILTON.
