1 Claim.

This invention relates to staple pullers, and has for its object providing a simple device for pulling staples, and so arranged that both prongs of the teeth will always be withdrawn simultaneously. It sometimes happens that one of the prongs is withdrawn easier than the other end, as a consequence, the ordinary staple puller is not very effective, as the staple simply bends and is held in the board by the other prong. The

object of this invention is to provide a staple puller that will insure both prongs being forced outwardly at the same time. A further object is to provide a puller that will temporarily hold the staple after it is pulled until it is removed or thrown into any receptacle desired.

Of the accompanying drawing, Fig. 1 is a plan view of the staple puller, showing it applied to a staple in a board, embodying one form of my invention; Fig. 2 is an elevation of the same; and

Fig. 3 is anenlarged fractional elevation of the head of the puller; Figs. 4 and .5 are elevations of modified forms of the staple puller; and Fig. 6 is an enlarged plan view of the head of the puller of Fig. 5.

My staple puller comprises a handle 10 and a head which consists of a pointed tongue l1, which is adapted to pass under the staple 12, which is to be pulled from a board or any other article. With a staple puller which comprises merely the tongue 11 adapted to pass under the staple, as stated, it often happens that one prong of the staple is pulled out before the other, and the staple puller is then ineffective in removing the remaining prong.

In order to prevent this, I provide fingers 13, which project out from the handle and are spaced somewhat above the tongue 11, so that they pass over the staple. With this arrangement, when the staple is pulled by pressing the handle l0 downwardly, the iingers prevent either prong from being elevated more than the other prong.

As a consequence, both prongs are necessarily pulled out together, without reference to the rey sistance which either prong offers to being forced 4" from the board.

In this manner, it is necessary only to set the sharpened tongue under the body of the staple and press the handle downwardly, and the enm tire staple will be removed; and, at the same L time, the body of the staple will be positioned between the tongue and the lingers and will be held loosely until removed by the operator, either by his lingers or by throwing the staple off from the puller into any desired receptacle.

The staple puller, preferably, has a loop 15 on the outer end of the handle, and a suitable curve 16 is formed adjacent the head of the puller. In case of Figs. 1 to 3, the tongue l1 is riveted to the under side of the handle l0, and the fingers 13 are integral with the main portion of the 60 handle, the iingers being formed by forming a V-shaped recess 18 in the end of the handle member. In this way, no bending of the fingers of the tongue is required, except at the bend 16, and by suitably shaping the tongue, as indicated, the ngers will be placed properly above the tongue to suitably hold the body of the staple as it is being extracted.

However, in case of Fig. 4, I show a modification, in which the ngers 20 are integral with 70 a strip 21 which is riveted to the upper side of the handle 10, and the tongue 22 is formed as an integral projection from the handle itself.

In case of Figs. 5 and 6, a modification is shown which comprises the handle 10 with the fingers 26 15 all integral with the handle, and the tongue 25 is bolted to the handle, so that it can be readily removed, if desired. Also, in this case, lugs 2'7 snugly clasp the edges of the handle and hold the tongue rigidly in place.

In case of the modication of Figs. 2 and 5, the tongue can be made from material unlike the handle; for instance, it may be of tool steel, so as to be better adapted to the work than the ordi- 4 nary cold drawn iron. Similarly in case of the modification of Fig, 4, the fingers may be made of diiTerent material; and, in either case, the two elements may very conveniently and cheaply be formed and assembled.

By providing the bend 16 in the pullers, the 96 staples are pulled by merely pressing the handle downwardly and, thus, it is unnecessary for the tongue to project beyond the staple, as would be the case if the staple were pulled by forcing the handle upwardly with the fulcrum at the end of the tongue.

I claim as my invention:

A staple puller comprising a handle having a pair of integralngers projecting longitudinally from one end thereof, and a member iixed to that end of the handle and projecting outwardly longitudinally therefrom substantially as far as the ends of the fingers and normally beneath the fingers, the outer end of the member being pointed, and iianges projecting upwardly from the side edges of the member snugly along the edges of the handle, the member being detachably xed to the handle.
