1 Claim.

This invention appertains to tools and more particularly to 'a novel wrecking tool for facilitating the removal of floor boards, roof boards, siding, and the like, from buildings being torn down. I

I One of the primary objects of my invention is to provide a strong and rugged wrecking tool which will effectively straddle joists, beams or studding, for effectively engaging under the boards, whereby the boards can be pried loose with a minimum amount of effort and with a minimum amount of damage to the boards, nails,

etc. I

.Q'F I E showing the tool in side elevation and in opera- .Another salient object of my invention is the provision of a wrecking tool embodying a cylindrical fulcrum body having formed thereon an elongated operating lever with detachable prongs or lifting fingers for straddling the studding or beams for engaging the boards to be removed.

A further important object of my invention is to provide novel means for detachably associating the lifting fingers or prongs with the cylindrical fulcrum body, whereby the position of the fingers or prongs on the body can be reversed whereby the operating lever can be effectively actuated toward or away from the operator to remove boards according to the position of the operator relative to the boards and beams.

A still further object of my invention is to provide a wrecking tool of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost;

With these and other objects in view, the invention consists in the novel construction, ar-

rangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawing, in which drawing:

I Figure l is a side,elevational view of my improved wrecking tool showing one position of the lifting fingers or prongs in full lines.

. Figure 2 is a view similar to Figure 1 but showing the fingers or prongs in their reversed position and the tool ready to be actuated.

Figure 3 is a top, plan view of the tool with parts thereof broken away and in section.

Figure 4 is a fragmentary, sectional view taken substantially on the line 4---4 of Figure 1 looking in the direction of the arrows.

. tion is the fact that the fingers or prongs I3 can V Figure 5 is a fragmentary, plan view showing 7 the tool in use for removing floor boards.

Figure 6 is a detail, fragmentary, sectional view tive position for removing floor boards.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter T generally indicates my improved wrecking tool and the same includes a solid cylindrical body I0 which is adapted to be placed against a beam, joist, studding, or the like when the tool is in use. Formed on or secured to the body I0 is the centrally disposed radially extending operating handle or lever II. This handle or lever is relatively long so as to'facilitate the manipulation of the tool. v I The opposite ends of the cylindrical body In have formed therein diametrically extending grooves I2 which form sockets for detachably receiving the inner ends of the lifting prongs or fingers I3. The fingers I3 are detachably held in their grooves or sockets in any preferred. manner, such as by the use of screws I4, which extend through the fingers and into opposite ends of the body. -As illustrated, the fingers or prongs also extend radially from the body, but at an angle to the handle. The forward ends of the fingers or prongs I3 can have their lower faces tapered, as at I5, for facilitating'their engagement with the parts to be removed. I

In Figures 5 and 6 I have shown one use of my wrecking tool and in these figures floor joists I6 support floorboards II. 4

In operation of my tool, the body I0 is placed on the desired joist and the fingers I3 are shoved under the adjacent floor board II. The handle II is now swung down toward the joist and the fingers will effectively lift up on the floor board and pry the board loose with a minimum amount of damage to the board, the joist and the nails. As clearly illustrated in these figures, the fingers or prongs will straddle the joist and effectively engage the board on each side of the joist. One of the important features of my invenbe readily removed and the position thereof reversed so that the tool can be eifectively operated in different positions.

As illustrated inFigure 2, the fingers I3 can be removed and repositioned in the grooves or sockets I2 so that instead of projecting forwardly from the tool, the same will project rearwardly from the tool. Hence, in Figure 1 the fingers are shown extending at an obtuse angle relative to the handle, while in Figure 2, the same are shown extending at an acute angle to the handle. In Figure 2 the lever is actuated by pulling action,

2 1 v 7 while in Figure 1 the lever is actuated by pushing action. This facilitates the use of the tool on the inside and outside of a building.

Obviously, more than one groove I 2 can be pro- 7 vided on the opposite ends of the body l0 and 5 Where more than one groove is provided, the grooves will extend at anangle to one another so that the prongs can be positioned at various angles to the handle which will be most; advantageous for use by the operator. V 1

Changes in details may be made without departing from the spirit or the scope of my invention, but what I claim as new is: 1 1 A wrecking tool comprising a cylindrical fulcrum body, a centrally disposed elongated operating handle connected with said body and projecting radially from the outer face thereof, the
