A. NOWKA ET AL COMBINATI 0N TOOL Filed March 1927 Patented Nov. 1 1927.

UNITED STATES ALFRED NOWKA AND WALTER LIVINGSTON, OF HASTINGS, NEBRASKA.

COMBINATION TOOL.

Application filed March 15, 1927. Serial No. 175,540.

This invention relates to combination tools, and has for an important object thereof the provision of a device of this character facilitating the Wrecking operation and reducing the amount of material which is destroyed or rendered worthless in the wrecking operation.

A further object of the invention is to produce a device of this character which combines the functions of a wrecking bar, chisel, hammer, or wedge.

A further object of the invention is to provide a construction of wrecking bar which will prevent, in a large measure, damage resulting to the hands of the user when the bar slips from a faulty hold.

These and other objects we attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of our invention and wherein Fig. 1 is a side elevation of a combination tool constructed in accordance with our invention;

Fig. 2' is an edge elevation thereof;

Fig. 3 is a plan view thereof; and

Fig. 4 is a fragmentary side elevation of a slightly modified form of tool.

Referring now more particularly to the drawings, the numeral 10 designates a central or handle portion of abar which at one end has a portion considerably offset, as at 11, and having its outer face 12 formed to provide a striking face or hammer head.

Fromthe extremity of this offset portion, an extension 13 is provided, which is transverse to the axis of the bar and has its central portion overlying the axis of the bar. The terminal of this extension 13 is flattened and sharpened in the general plane of the bar to provide a chisel l4: and this chisel is c'entrally notched, as at 15, to enable use of the same as a claw for drawing nails and the like.

At its opposite end, the bar is likewise offset, as at 16, this offset being considerably less than the offset providing the portion 11. At the terminal of the offset 16, an angular wedge-shaped extension 17 is provided, which is disposed at an obtuse angle to the handle portion 10. The inner face, or that face more nearly adjacent the axis of the bar of'the offset portion 16, is flattened to provide a blow face 18 against which a hammer may be impinged to force the wedgeshaped extension 17 between two elements which are to be separated. The offset portion 16 is relatively short and its junction with the wedge-shaped portion 17 provides a heel 19 about which the bar may be rocked as a pivot, when prying, to loosen an article beneath which the wedge has been forced. After the article has been elevated a short dis tance to a point where the bar would tend to pivot or fulcrum for the wedge-shaped por- I tio-n longitudinally of the bar, decreasing the leverage force provided and at the same time checking the rapid increase of the angle between the wedge and the element with which it is engaged.

It is pointed out that since the wedgeshaped extension 17 and portion 13 are arranged in the same plane and the terminal portions of the portion 13 extend to, opposite sides of the handle, these portions will engage a surface upon which the heel 20 is pivoting before the handle 10 comes into contact therewith, thus holding the hand of the user out of contact with this surface. It is further pointed out that the angular extension 13 provides a handle, permitting location of the hand of the user upon the axis of the bar. where the bar is to be used-with a twisting motion. If desired, the handle 10 can be provided with an opening 22 through which one of a pair of wires which are to be twisted may be passed.

"In Fig. 4, we have shown a modified coustruction of the lever end of the tool. In this form of the invention, the bar 10 has an angular extension 23, which tapers toward its extremity. The extremityQet is disposed at an angle to the angular extension and faces somewhat toward the handle end of the tool. This extremity istapered, so that it may be employed for pulling staples and twisting wire in addition to its functions which it may perform as a wrecking bar. It is pointed out that to a great extent, the same effect is produced by this structure as is produced by the structure previously described, in that the camber 25 of the junction between the angular extension .and its extremity and the camber 26 at the junction of the angular extension with the bar, providethe lever points, which successively form pivots for the extremity 24 and the lever formed by the bar 10. The camber 26 may he formed as a hammer head to facilitate engagement of the extremity 24 in a staple or other element.

inoe the construction of the bar may be slightly altered Without in any manner departing, from the spirit of the invention, We do not limit ourselves to the construction hereinbefore set forth except as hereinafter claimed.

We claim A combination tool comprising a handle having an ofi'set adjacent one end, the ofiset rename having a tapering angular extension, the an gular extension projecting away from the axls of the bar whereby the heel at the junction of said angular extension with the ofiset and the heel formed at the junction of the
