WIRE CRIIVPlNG AND FASTENING PLIERS.

SPECIFICATION forming part of Letters Patent No. 576,503, dated February 2, 1897.

Application tiled April l5, 1896. Serial No. 587,677. (No modclfi Be it known that I, JOHN S. IVILLIAMS, a citizen of the United States,residing at Jerseyville, in the county of Jersey and State of Illinois, have invented a new and useful fire Crimping and Fastening Pliers, of which the following is a specification.

This invention relates t-o wire crimping and fastening pliers and is in the nature of an improvement on the implement shown and described in Letters Patent No. 526, 766, dated October 2, 1894:, granted to Eugene Il. iVilliams and myself.

The objects of the present invention are to adapt the device to be used with greater facility upon the lower horizontal or line wires of a fence and to so arrange the jaws and connect them with their operating-levers th at progressively-increasing leverage will be afforded as the jaws move toward their closed position. These and other objects and advantages of the invention will be pointed ont in the subjoined description. Y

The invention consists in certain novel features and details of construction and arrangement of parts, as hereinafter fully described, illustrated in the drawings, and embodied in the claims hereto appended.

In the accompanying drawings, Figure 1 is a perspective view of the improved implement constructed in accordance with the invention, showing the jaws open. Fig. 2 is a side elevation of the same, partly in section, showing the jaws closed and in the act of crimping the wires at their point of intersection. Fig. 3 is a front end View with the jaws thrown open and the intersecting wires and staple in readiness to be operated upon. Fig. is a similar view showing the jaws closed and the tie coinpleted. Fig. 5 is a detail perspective view showing the completed tie as applied to the intersection of the cross-Wires.

Similar numerals of reference designate corresponding parts in the several figures of the drawings.

The pliers are constructed, in the main, in a manner similar to the pliers described in the patent above referred to, comprising a stationary jaw 1 and a pivoted jaw 2. The pivoted jaw 2 is formed at each side of its center with similar recesses 3, the same being bounded at the outside by parallel ears 4 and at the inbetween the jaws.

side by a central die 5, having in its inner face an arc-shaped seat G-for the reception of the head or looped end of the staple, which forms the tie for the cross-wires. The stationary jaw 1 is provided with a notch or recess 7, in which the die 5 is received, and with parallel arms 8, which fit into the recesses 3 in the opposing jaw when the pliers are closed, the jaws being thus adapted to interlock. The central die 5 has oppositely-disposed shoulders 9, which, as the jaws are closed, pass beneath overhanging lips 10 upon the inner adjacent surfaces of the arms 8. The base of the recess 7 forms a guiding-notch 1l, which opposes a corresponding notch 12 in the central die 5 of the other jaw. These notches receive the vertical wire when the jaws are thrown open and effect a crimping of such wire when the jaws are closed in a manner that will be hereinafter explained. Channels 13 areformed in the inner adjacent surfaces of the arms 8, the same forming dies for the reception of the extremities of the staple forming the tie. The channels 13 are curved for the purpose of deflecting the terminal portions of the staple and causing the same to pass in front of the horizontal wire and to return again tothe rear of the vertical wire.

In operation the implement is applied to the intersection of the vertical and horizontal wires of the fence or other structure, so that the vertical wire (indicated at 14) is received in the guiding-notches 11 and 12, with the horizontal wire extending transversely As the jaws are closed the vertical wire is bent or crimped backward and is received in the notches 15, formed in the bases of the jaws. In the same operation the horizontal wire is bent or crimped forward at the point of intersection in the manner clearly shown in Fig. 5. The jaws are now thrown open again and a staple 16 inserted between the jaws so that its head or loop end is received in the seat 6 inrear of the vertical wire above the horizontal wire. The terminals of the staple are arranged in front of the horizontal wire and engaged in the channels 13, whereupon in the closing of the jaws the extremities of the terminals of the staple are caused to traverse the said channels 13 and upon reaching the bases of ICO said channels in the stationaryjaw to be curled thereby and caused to wind around and closely embrace the vertical wire below the intersection thereof with the horizontal wire.

Both of the jaws are provided at one side with angular recesses 10, within which are arranged wire-cutters 17. 'Ihe cutter which is attached to the stationary jaw is of an L shape, comprising a notch 18, in which is received the working edge of the opposing cutter attached to the pivoted jaw and also a bearing edge or seat 19, against which the wire is placed preparatory to its severance. This forms an eifective and powerful wirecutter and adds to the value and utility of the implement. The stationary jaw is formed with a tapering socket or thimble portion 20, adapted to receive the correspondingly-tapered extremity of a suitable handle 21, and is also provided with twin ears 22, between which is pivotally mounted the pivoted-jawoperating lever 23. This operating-lever is formed with an elbovr extension 25, from which a pivotal connecting-link 26 extends through a slot 27 in the base of the stationary jaw to the inner end of the pivoted jaw, to which said link connects pivotally. As the operating-lever 23 is vibrated about its fulcrum t-he point of attachment of the link 26 to said lever swings around the said fulcrum, and in such movement the throw of the link 26 is decreased and the leverage upon the pivoted jaw is correspondingly increased, thus affording a progressively-increasing leverage. The operator is thus enabled to perform a greater amount of work in a day, as the increased leverage makes the implement much easier in action. Besides,

the stationary j aw may be placed close to the ground and the operating-lever of the pivoted jaw operated from above the handle of the stationary jaw without it being necessary to move the latter.

It will be apparent that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacricing any of the advantages of this invention.

Having thus described the invention, what is claimed as new is- 1. The combination with the stationary jaw provided with the handle-socket and slot as described, of the pivoted jaw fulcrumed intermediate its ends on the stationary jaw between the slot andthe point thereof, the operating-lever therefor, and the pivotal conmeeting-link interposed between said lever and pivoted jaw and passing through the slot in the stationary jaw and connected to the inner end of the pivoted jaw, substantially as described.

2. The combination with the pivoted jaws formed at their outer ends with wire-crimping iingers and provided in rear of their pivotal connection with lateral recesses, of wireeutters removably tted in said recesses, the said cutters being actuated by the same operating means as the jaws, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
