TOOL.

Application filed `March 8, 1924. Serial. No. 697,781.

Tardieu/011i t 11mg/ concern.'

Be it known that I, Ritiri-r A. SQUIER, a citizen of the United States, residing at Tieten, in the county of Yakima and State of lVashington, have invented certain'new and useful Improvements in Tools; and I dohereby declare the following to beja full, clear, and exact description of the 1nventidn, such as will enable others skilled` in the art to which it appertains to make and use the same. i l

The presentinvention relates to tools,` an more particularly to that class of such devices as are used for driving in nails and the like.

An object of the present invention is to provide a hatchet or hammer used particularly in making wooden boxes and which is provided with an impact surface of such construction as to prevent the slipping of the hatchet or hammer on the hea-ds of the nails in withdrawing the nails fro-1n the stripper or feeder which is used where wooden boxes are made in large quantities.

Another feature of the invention is to provide the head of the tool with an impact surface composed of a multiplicity of teeth which have their axes inclined to the base of the teeth, so that by impact of the head of the tool against the nails as they come from the nail stripper the nails are driven in by a direct impact in line with the nails even though the tool must be struck by a glancing blow against the heads of the nails.

A further object of the invent-ion is to provide the head of the tool with an impact surface which is stepped or composed of a plurality of inclined surfaces which are adapted to divert glancing blows into direct longitudinal impact against the heads of the nails, so as to drive the nails in a straight line and prevent the-m from assuming an inclined position or from springing out of position when struck.

Another object of the invention is tol provide a nail driving tool with a head whose impact surface is composed of a multiplicity of relatively small independent and inclined surfaces approximately of the size of the head of the nail so as to fit against the heads of nails and divert glancing blows into longitudinal thrusts against the hea-ds of the nails.

With the foregoing and otherobjects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claim appended hereto.

In the drawings, wherein like symbols refer to likeor corresponding parts throughout the several views,

Figure 1 is a perspective view of a nail driving tool constructed according to the present invention, the same in the "present instance being embodied in the form of a stripping hatchet.

Figure 2 is an outer edge view of the tool of Figure 1, showing the inclined teeth on the impact surface of the head.

Fligure 3 is a side elevation of the same, anc

Figure 4 is an enlarged face view of the impact head, showing the arrangement of the inclined teeth. i

Referring to the drawing the present in vention is embodied in a stripping hatchet having a blade portion 10, an intermediate socket portionll in which is suitably secured a handle 12, and a head or striking portion 13 which is arranged oppositely to the blade 10.

The head 13 preferably has a slightly conveXed striking face 14.- which is made up of a plurality of relatively small projections or teeth 15 of substantially pyramidal form, but whose axes are inclined relatively to the surface 14 and provide a number of independent inclined striking faces 16 adapted to directly engage the heads of nails so as to divert glancing blows of the head 13 into longitudinal thrusts against the head of the nai As shown in Figures 2 and 4 the teeth 15 may be all inclined in one direction, such as to the left as shown in Figure 4 so that glancing blows of the tool against nails which are held in the stripper will cause the inclined faces 16 to engage the heads of the nails and divert the saine directly downward for freeing the nails from the stripper and for initially placing the nails in the work. As it is necessary to continuously use the tool without interruption the tool may be continuously struck against the nails as the work is drawn away from the stripper and may then be brought into engagement with the next succeeding nail so as to free it from the stripper and initially place it in the work. Necessarily during such manipulation of the tool the same is impacted by a glancing blow against the head of the nail in the stripper and also against the nail as Cil the ivo-'rk is drawn from beneath the chute Of course the inclination of the sides or faces 16 of the teeth may be varied or dis posed at different angles and in different directions to meet various Iconditions of use which may be found more advantageous for different classes of work and for diferent kinds of stripping,` machines.

The particular structure which is disclosed in the accompanying drawing is for use by a right han'd Worker, but of course the teeth 15 may be inclined in an opposite direction for a left hand Worker or 'to -meet other requirements.

It is obvious that various changesl and modifications maybe made in the detailsof constructioii and design of the above specifically describe'd embodiment of this invention Without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim.

What is claimed is A nail driving' tool for use in connection With nail stripping machines, comprising a body portion having a head with an impact surface composed of a plurality of independent teeth, each tooth having a flat face on one side extending outwardly at substanti'ally right angles to the impact surface and having an inclined contact face at its oppositev side, said flat faces of all of the teeth facing` in one `direction toward said nail stripping machine and all of said inclined Contact faces extending away from said machine for impact with the heads of nails to deflect glancing blows thereon of the tool into an impact force coaxial with the nails to drive the same straight into the Work.
