' COMBINATION TOOL.

Application filed December 21., 1922. Serial No. 608,338.V

.To all 'Lu/0m zi may concer/n:

Be it known that I, KENNETH MAGPHER- soN, a subject of the King of Great Britain, and resident of the town of Nanton, Province of Alberta, Dominion of Canada, have .invented certain new and useful Improvements in a Combination Tool, of which the following is a specification.

This invention relates to compound tools and has for its object the provision of a single tool of simple and compact form by the use of which all the operations involved in the Stringing or repairing of wire fences may be easily performed. The invention is illustrated in the accompanying drawing' and will be hereinafter fully set forth.

In the drawing, Fig. 1 is a perspective view of a tool embodying the invention,

Fig. 2 is a side elevation of the working end of the tool, j

Fig. 3 is a longitudinal horizontal section on the line 3-3 of Fig. 2,

Fig'. el is a detail section through one of the heads on line iwi of Fig. 2, and

Fig. 5 is a detail perspective view of one of the staplepulling plates. Y

In carrying out my invention, I employ two similar mating members each comprising a lever or handle 1, a body 2, and a head 3. The body portions 2 are of less width than the heads and the handles and are pivotally connected by a central transverse pivot bolt 4f, as clearly shown in Fig. 3. Said bolt is secured in position by a nut 5 which is seated in a recess in the outer side of one body whereby it is held against turning while the bolt is driven home. Each head. and lever extends approximately tangentially from the respective body portion and they spring from diametrically opposite points of the body whereby the heads will be brought together when the handles are brought together and moved apart when the handles are separated. Each body portion is provided with a notch 6 at the base of its head through which a strand of wire may be inserted so that if the bodies be moved pivotally in opposite directions the adjacent opposed end edges of the notches will be moved past each other and will make a shearing eut through the wire. On the opposed faces of the heads are gripping blocks 7 which may be caused to clamp a wire and hold .it while it is being bent or perform other functions of a pair of pliers. On the outer face of one head is provided an outwardly projecting hammer head 8 and on the outer face of the other headv is an outwardly projecting claw 9, the functions of which are thought to be obvious.

Removably inset on the outer face of each head is a plate 10, the forward edge 11 of which is arcuate to constitute a urocker and the inner forward corner of which presents a tooth 12. By engaging opposed teeth in a staple and then rockingthe tool upon an edge 11, the staple may be readily withdrawn from a post or other body in which it may be embedded. The withdrawal of an unusually long staple may obviously be facilitated by continuing the rocking of the tool upon either the hammer head or claw member as a fulcrum. The staple-pullers are flat plates, as clearly shown, and are secured to the sides of the heads byscrews 13 inserted through central openings lll in the plates and may be quickly replaced when broken inasmuch as it is necessary merely to remove the fastening screw 13 whereupon the broken plate will drop olf the head and a new plate may be quickly substituted therefor. Upon reference more particularly to Figs. l and 3, it will be noted that the heads are slightly recessed on their sides to receive the plates thereby presenting shoulders 15 against which the rear edges of the plates may abut so that the breaking strain thereon will be more effectually resisted. The accessibility and ease of removing the plates 10 appears obvious. The inner surfaces of the levers, immediately adjacent the body portions, are corrugated, as at 16, and provided with transverse ribs or shoulders 17 at the rear ends of the corrugations so that wire strands may be very firmly secured in order to be stretched. It will be readily seen that when used as a staple puller the plier abutments 7 co-opervate with the points l2 in preventing wire which passes through the staple from flying free, while the notches 6 may be used at such times, if needed, to part any interfering wires. The co-operating function of the claw and hammer members has been set forth heretofore, namely as providing additional fulcrum points.

My tool is very simple, compact, and inexpensive and its uses are thought to be clear from the foregoing description taken in connection with the accompanying drawing.

Having thus fully described my invention, what I olaimes new and desire to secure by Letters Patent ol the United States 1s:-

l. A fence tool comprisingn two similar members recessed intermediate their ends for pivotal union with euch other, theone member including s removable staple-prillingl element inset on the-outer tace thereof, u plier jen', :i hummer heed, and s Wire outtingedge; the other member including;` a removable staple-pulling element Y similarly inset, fr plier jen', e elan* :element7 ande wire cutting edge, seid element-s nnetioir ing` infpairs'upon eo-:ietion ot the-two inembers.

2. A tool of the class describedcomprising` two body portions pivoted together side by side, handle members` extending rearwardly trom the body portions, heads extending forwardly 'from the body portionsr` one of saidliezidslmving 'formed thereon an `integre-l hammer member; the other heard having termed thereon an integral ehm' member. removable staple-pulling plates inset in the outer Juee ot each i d); member adjacent seid hummer yand elan' members respectively, und iplier-termine` almtments formed.integral with said body portions between vSeid hammerv and claw members.

ln testimony whereof hereunto etlix my signature.
