GEORGE MILLIKEN, OF ORANGrEVILLE, ILLINOIS, ASSIGNOR OF ONE-HALF T0 WILLIAM A. MOORE, 0F ORANGEVILLE, ILLINOIS.

HAIVIMER BLADE ATTACHMENT.

Application filed July 20,

1 0 all whom. it may concern Be it known that I, Gnonon MILLIKEN, a citizen of the United States, residing at Orangeville, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in a Hammer Blade Attachment; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in'the art to which it appertains to make and use the same.

The invention primarily aims to provide means whereby a hammer may be converted into a hatchet when an article of this nature is required, thereby obviating the necessity of providing two independent tools which take up room, increase the weight of a kit and add to the cost.

In accordance with this hatchet blade of usual outline is provided at its coupling end with a curved slot whose outer wall conforms to the outline of the claw of a hammer to fit the same snugly and is of such width as to engage the elements or furcations of the claw and obtain a firm scat thereon, and whose'inner wall is of wedge form to snugly fit the cleft of the claw and bindingly engage the flared walls thereof to bracingly hold the blade against all ordinary stresses to which a hatchet is subjected.

Other objects and advantages will be ap parent and suggest themselves as the nature of the invention is understood.

While the drawing illustrates an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion, and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawing forming a part of the specification,

Figure 1 is a side view of a hammer provided with a hatchet blade detachably connected thereto in acordance with the present invention,

Fig. 2 is a detail view of the blade,

Fig. 3 is an end view of the hammer and blade, and

Figure 4 is a sectional detail on the line 4: 4: of Figure 1.

Corresponding and like parts are referred to in the'following description and desiginvention a 1921. Serial No. 486,138.

nated in the several views of the drawing by like reference characters.

The hammer illustrated is of ordinary construction and is shown to demonstrate the application of the invention and comprises a head 1, hub 2, and claw 3. The walls of the cleft forming the claw flare inwardly in the usual way and advantage is taken of this feature in thepresent invention whereby tobracingly' and wedgingly secure the blade when in position.

The hatchet bladed is of usual outline and its inner or coupling end is provided with a curved'slot 5 whose outer. wall 6 conforms to the outline of the claw 3 so as to fit the same snugly. The wall 6 is of such width as to engage the furcations or elements of the claw 3 upon opposite sides of the cleft to give proper and substantial support to the blade. The inner wall 7 is of tapering form to enter the cleft of the claw 3 and wedgingly engage the side walls thereof to retain the blade in position and sustain the same against all stresses to which the blade is subjected when in active operation. The inner tapered wall 7 projects some distance beyond the inner end of the curved slot 5 to provide shoulders upon opposite sides of the blade 4 adapted to have wedging engagement with the walls of the cleft of the claw. In other words. the inclined sides of the tapered wall 7 submerge or vanish into the sides oft-he blade 4. The inner upper portion 8 of the blade 4: is adapted to obtain a neat and snug fit in the angular space between the hub and the claw of the hammer as indicated most clearly in Fig. 1. The outer upper portion 9 of the blade 4 projects outwardly of the eye of the hammer to provide a shoulder for receiving blows delivered upon the blade 4 to detach the same from the hammer when required.

The hatchet blade 4 is especially constructed to fit the claw of the hammer with which it cooperates. 'VV hen a hatchet is required. the blade l is placed in position by a curved sliding movement, the tapering wall 7 entering the cleft of the claw 3 and wedgingly engaging the walls thereof thereby retaining the blades in position. Blows delivered upon the edge of the blade 4 serve to ti hten the same by driving the tapering wall I into the tapering cleft of the claw 3 as will be readily. appreciated.

Having thus described the invention, what I claim is A hatchet blade attachment for ciawhammers comprising a blade having an arcuate slot extending inwardly from one edge thereof, one Wall of said slot conforming to the outer contour of the claw o'l' hamn'ier and of a Width sullieient to engage both elements thereof, the other wall of said slot bein shorter than the first-mentioned Wall and adapted to enter the cleft of the clan and Wedge tightly against the Walls thereof, said blade having tapering inclined grooves on its opposite sides and extending from the end of said slot and adapted to Wedgingly receive the inner edges of the view element when the blade is positioned on a hammer, said blade having itsouter upper portion disposed outwardly of the eye of the ham-- iner to provide a shoulder for receiving 20 blows delivered to detach said blade from the claw, and the inner upper edge of said blade being rounded to snugly fit the space between the hub and claw of the hammer.

In testimony whereof I afiix my signature 25 in presence of two Witnesses.

GEORGE MILLIKEN. Vitnesses E. M. Hansen, Esrnnn M. ULARUD.
