WRECKING TOOL.

Application filed ma 13, 1924 Serial No. 712,994.

To all whom it may concern.

Be it known that I, SUMMER F. WHITE, a citizen of the United States, and a resident of Portland, county of Multnomah, and

State of Oregon, have invented a new and useful Improvement in Wrecking Tools, of which the following is a specification.

The object of my invention is to provide a pick-like tool which is especially adapted for use in wrecking buildings, and the like, where the material is to be salvaged and for that reason the material must be removed with the least injury.

The particular object of my invention therefore is to provide the said tool with a portion which engages the overlying base from which another is pried off in such a manner that the tool will not slip therefrom when pressure is applied.

My invention has for its further object the provision of a combination tool which can be used as an adz, a hammer and a pry. Heretofore it has been preferable, if not necessary, for each workman to carry an ax 25 or an adz, a hammer and a crow or pinch bar, for performing all of the duties necessary when a building is being dismantled.

There is no convenient place for a workman to store his tools, and he must therefore 30 carry the said tools about with him. This is generally inconvenient because he is often required to work in cramped quarters and in places where he must have the use of both hands to perform his work.

I attain the before mentioned objects and others incidental thereto in a tool of the character described which has a curved head mounted on a handle, the head having one portion extending a substantial distance from one side thereof, the head being tapered to a sharp edge of substantial width so as to provide a cutting edge which may be used as an adz. The top surface of this end is also curved and provided with means adapted to bite into the structure against which the head bears, thus to provide an effective purchase for preventing the tool from slipping therefrom when used in a prying operation. This means preferably consists of an elongated cavity substantially the same width as the width of the head, the cavity being centrally arranged on the head so as to provide two substantially thin side walls which have more or less sharp edges constituting two spaced ridges which bite into the structure thus securing the firm purchase herebefore mentioned.

The detailsof construction and mode of operation of my device are hereinafter clescribed with reference to the accompanying drawings. y j l In the drawings:

Fig. 1 is a perspective view of the tool inserted under a section of flooring and bearing against a joist;

Fig. 2 is a perspective view of the pick head showing the means for engaging the joist when pressure is applied to remove a board therefrom;

Fig. 3 is a fragmentary view of the pick end ofthe tool shown partly as a longi- V tudinal section;

Fig. 4 is a fragmentary perspective of my device engaging a joist, with the end of the pick broken off along the line 44 of Fig. 2; and

Fig. 5 is a fragmentary elevation of my device and shows how it may be driven behind a tightly nailed board.

My improved tool is preferably made up with a sharp edged adz end a and a hammer head 6 and is provided with an eye 0 in which the handle (Z is inserted. The adz end as is gradually tapered to a point and its under surface is curved on a long are. The are extends not only along the under surface of said end, but also along the under surface of the eye and along the under surface 7' of the head so that when the pick is placed behind a board, as g, fastened to a wall it, the pressure may be gradually increased to pry the board from place merely by tipping the handle and changing the point of contact between the tool and the Wall.

The main feature of my tool, however, consists in forming a recess 6 on the under surface of the adz end of my improved tool, which cavity is substantially the same width as the width of the adz end, thereby forming two walls j and y" at each side of the cavity 71 which are of such relative thinness that when pressure is applied to the tool as when it is used to pry off a board, and it is rocked on its under surface, the side walls j and j tend to bite into the joist 70 or other relatively fixed member so as to pry or lift the boards Z from place without slipping. This permits the tool to be placed at an angle to the joist as shown in Fig. 1 instead of having to be driven directly over the joist. This not only is easier for the Workman, because it permits him to place his pick to one side of the'joist and thus save the time and energy required in driving the pick between the board and the joist, but also permits the board to be removed with less chance of splitting the same. relatively thin Walls j are not provided on the bottom surface a of the tool and an effort is made to pry the boards loose, the pick Will slide off the joist until the end of the pick is placed very closely alongside of the joist or unless a tool of irregular outline is provided.

I claim:

1. In a tool ofthe character described, a head having a centrallylocated eye for receiving a handle, the head at one side of said 7 eye being formed as a hammer, the other If the side of said head being tapered to a sharp edge, the top surface of sald tapered end being formed on a continuous curve, and

being provided with relatively sharp spaced parallel lips for the purpose specified.

2. In a tool of the character described a head having a centrally located eye for receiving a handle, the head at one side of said eye being formed as a hammer, the other side of said head being tapered to a sharp edge, the top surface of said tapered end, said eye and said hammer end being formed on a continuous curve, and being provided With a cavity occupying substantially the entire width of said head, thus providing tWo relatively sharp thin lips for the purpose specified.

SUMMER F. lVI-IITE.
