SPECIFICATION forming part of Letters Patent No. 367,393, dated August 2, 1887.

Application filed October 2Q, 1886. Serial No. 216,977. (No model.)

To all whom t may concern: Be it k-nown that we, DAVID HENRY HAZ EN and DAVID HANNAH KIEKPATRIOK, citizens of the United States, residing at Francesville, in the county of Pulaski and State of Indiana, have invented a new and useful Improvement in Fence-Machines, of which the following. isV a specification.

Our invention relates to au improvement in machines for making picket fences; and it consists'in the peculiar construction and combi- 4 perspective view of one of the needles.

nation of devices, that Vwill be more fully set forth hereinafter, and particularly pointed out in the claims. f

In the drawings, Figure l is a perspective View of a fence-machine*embodying our improvements. Fig. -2 is a vertical sectional viewof the same. Fig. 3 is a similar View taken on a plane at right angles to Fig. 2. Fig. 4 is a top plan View. Fig. 5 is a detail Fig. 6 is a top plan vienT of a fence-machine embodying our improvements.

A represents a vertical rectangular frame, which is supported upon runners or shoes B, the function of which is to adapt the frame to be moved easily on the ground. Transverse horizontal beams C connect the sides ofthe frame, and are arranged one above the other and at a suitable distance apart, and on the l pivotal bolts E, and also to rock thereon. In-

clined cams F are secured on the upper sides of the beams C and are arranged under the levers D, the said cams extending in opposite directions on opposite sides of the pivotal bolts E, so that one end'of each lever D will be raised at the same time that the opposite end of the lever is lowered. When the said levers are parallel with the beams C, they are level; but when they are moved in either direction towardor from the front side of the frame, their opposite extremities y are alternately raised and 'lowered by the inclined cams, as will be readily understood. The long ends of the levers D are connected together by a vertical bar, G, 'so that the said levers will move simultaneously, and a hand-lever, H, is fulcrumed to one side of the frame A and has its lower end connected lo the bar Gby means of a link, I.

K represents vertical needlebars, which are arranged on the inner sides of the frame A and are guided in suitable horizontal guidingyokes, L, with which the inner sides of the frame are provided. These needle-bars are of any suitable length, and are connected to the levers G by means of arms M.

N represents needles, which havetheir inner ends attached to the inner sides of the bars K and project outwardly from the said bars for a slight distance beyond the front side of the frame. Any desired number of these needles may be attached to the needle-bars, according to the number of strands of wire which are to be employed in making the fence, one needle being used for' each Wire. outer end of each needle is pointed, as shown, and is provided on its upper side with a bayonet-slot, O.

I? represents spiingplates, which are pivoted to the outer ends of the needles and bear against one side thereof, the function of the said spring-plates being to close the inner portions of the bayonet-slots, and thereby prevent the wires which are strung through the said bayonetsslots from becoming accidentally disengaged therefrom. l

It will be understood that when the lever H is moved back and forth the needle-bars K will be caused to move simultaneously in opposite directions toward and from the front side of the frame, so that the needles attached to one bar will be withdrawn toward the frame at the same time that the needles attachedY to the other needle-bar will be moved Abackward and forward by the lever H. This action will cause the wires to bend slightly on each other, thereby preventing their slipping.

Having thus described our invention, we claim 1. The combination, with the frame having The the transverse beams C, of the levers D, pirYA eted centrally on said beams, the needle-bars eonneeted to opposite ends of the levers, and thereby moved simultaneously in opposite directions, and the needles attached to the said need'lebars and having` each an opening through which one oi' the wires may be strung, substantially as described.

2. The combination, with the frame having the transverse beams C, of the levers D, pivoted Centrally on sai d beams, the inclined ea ms arranged under the said levers on opposite sides of their pivotal points7 and thereby adapted to reek the levers when they are. moved, and the needle-bars eonneeted to the said levers and Carrying the needles through which the Wires are strung, substantially as described.

3. The combination, with the trame having the transverse beams G, of the levers l), pivoted Centrally o n said beams, the needle-hais the needles having the bayonet-slots, and the spring-plates to partlyr close the said slots, substantially as deserihed.

In testimony that we elaim the foregoing as our own we have hereto affixed our signatn res in presence el' two witnesses.
