NAIL-EXTRACTING PRYlNG--BAR.

SPEGEFICATIN forming part of Letters Patent No. 669,106, dated March 5, 1901. Application filed August S, 1900. :Serial No. 26,212. lNo model To @ZZ whom, t may concern,.-

Be it known that I, ALFRED G. THoM, a citizen of the United States, residing at Tankegan, count-y of Lake, and State of Illinois, have invented certain new and useful Improvements in Nail-Extracting Frying-Bars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable persons skilled in the art to which it appertains to make and use the Saillie.

My invention relates to improvements in woodworking-tools, and has special reference to a prying-bar wherein an effective nail-eX- tracting device is constructed integral there with.

The object of my invention is to provide a tool whereby boards, siding, and the like may be pried off and carefully removed without destroying their subsequent usefulness and whereby the nails by which they are attached to the structure may be easily and quickly extracted at the time when the boards are being removed.

My extracting device is made an integral immovable part in the body of the bar and is so arranged that nails may be readily and eX-.

peditiously extracted from the boards into which they have been driven and may be reclaimed in their original straight perfect condition.

The tool is especially designed for ripping up boards of wooden sidewalks and in extracting the nails therefrom, for removing the sheeting on the sides of ships, houses, dac., and for other similar work wherein it is desired to handle, pile, and preserve them for future use and for this reason to remove the nails therefrom readily and quickly at the same time and without injury to the nails.

There being no moving part to my device, it is quickly applied, readily manipulated, and not easily to be damaged, and it possesses an inherent quality of adjustment for all sizes of nails for which it may be used.

In the drawings, Figure l is a plan View of one side of my bar. Fig. 2 is a plan View of the reverse side. Fig. 3 is a side elevation of the said bar. Fig. 4 is a section through line t 4 of Fig. 2.

In all of the views the same letters of reference are used to indicate similar parts.

A represents the bar.' 'lhe surface of one side of the bar is indicated by a and that of the opposite side by a.

a2 is the handle, which may be of any con,- venient length.

a3 is a flat sharpened chisel-point at the end of the bar, made so for the purpose of being readily introduced under the boards. It is preferably made of steel formed into a rather chisellike point on both sides.

co* is a perforation that is drilled or otherwise made through the bar. Tapering recesses or depressions a5 and a are made on opposite sides of the said barand intersect the lateral perforation a4,leaving tapering wedgeshaped walls 01,7 and a8 on opposite sides approaching the surfaces a and a of the respective sides, as shown more clearly in Fig. 4. These wedge-shaped Walls nearly die out in the aforesaid perforation a, In the lateral emargined edge ofthe aforesaid Wedge-shaped walls tapering V-shaped slots a9 and am are cut or otherwise formed. The object of these slots is to permit the entrance of the body or shank of the nail and to prevent the head from passing therethrough when the tool is lifted for the purpose of extracting the nail.

The use and operation of my device are plainly evident. After the board has been pried up and the nail-head projects slightly above the surface of the board the tool is placed in position, so that the head of the nail will enter the perforation a4. The tool is then drawn toward the operator until the shank of the nail enters the slot a9. The end a2 of the tool is then raised from the point a3, which forms the fulcrum, the other end thereof is lifted, and the nail thereby withdrawn from the board; If the nail has not been com pletely extracted by this operation, the tool shaped notch may be cut into the point as for IOO the purpose of starting the nail, if desired, and the nail may be further acted upon by the notches agand d10 in the manner described. These modifications may be made without departing from the gist of my invention.

I-Iaving described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. A nail-extracting prying-bar,c0mprising a tapered point, a perforation extending laterally through said bar, a recess, or depression, extending obliquely from each side of said bar and terminating in said perforation, a Wedge-shaped, 0r tapered wall between said recesses and the opposite side of said bar, and a notch in the emargined edge of said tapered walls for receiving the shank of a nail, substantially as set forth.
