NAIL-DRAWING TOOL.

Application filed March 22, 1927. Serial No. 177,336.

This invention relates to nail drawing tools and more particularly to tools of this nature that are embodied in the form of a claw hammer such as are used by carpenters.

' One of the objects otthis invention is to provide a tool of this nature which is equipped to grip the shank of anail that has been partly withdrawn by the main claw of the han'nner, to complete extraction of such nail from a board or the like.

It is a special object of the invention to provide a tool of this nature whereby a mutilated nail, that cannot further be ex tracted by the hammer claw, may be gripped and quickly extracted. v

A further object of the invention is to provide the tool with means for gripping andextracting any size nail or the like from the smallestto the largest, one of the novel features being that any one of said devices or means may be en'iployed for a wide range of size of nails.

A further object is to so equipthe tool that the novel features thereof will be equally adapted to right or left handed workmen.

My invention ha many other objects and features which will be more fully described in connection with the accompanying drawing and which will be more particularly pointed out in and by the ap pended claims.

In the drawing;

Fig. 1 is a view in. side improved tool. showing the thereof on the right hand side.

liig. 2 a similar view of the lelft side thereol.

Fig. 3 is a view in elevation looking in the direction of the arrow in Fig. 1.

Fig. 4 is a plan view looking in the direction of the arrow shown in Fig. 2.

Fig. is an enlarged fragmentary view more clearly illustrating the nail imping ing equipment.

Like characters of reference designate similar parts throughout the dili'erent figures ot' the drawings.

Although I have shown the device of my invention embodied in a carpenters hammer, my invention may have utilities in ther embodiments and hence I do not eqi 1i pment hand wish to be limited to the exact form herein shown. As illustrated, the handle of the tool is designated at 1, and is fitted to the elevation oi my.

socket 2, in the usual manner. The body 3, which 18 formed integral with the socket 2,

is provided on one end thereof with the of said claw members at 12 and 13, and

their lower or rolling faces at 14 and 15, respectively. The fiat end 16, .of the body merges into the rolling faces lt and 15, as shown, and the inner edges 17 and 18 of the claw members (3 and 7, respectively, are in the usual converging relation so as to adapt them for the extraction of any size nail up to the point where the flat end 16 of the hammer rests on or reaches the surface from which the nail is being extracted. hen, if the nail has not been completely extracted, the device of my invention is brought into play, as will now be described in detail, the structure first, and then the operation.

As shown, the upper faces 12 and 13 are recessed at 19 and 20 to a gradually increasing depth from points inwardly oi the tips to points outwardly of the bases of said claw members, as will be clearly seen in Figs. 1 and 2. Thus, I form flanges on the lateral edges of the claw nien'ibcrs which flanges areliush with the outside faces of said members, and are indicated. In each flange, in accordance at 21 and with thls invention, I provide a plurality of nail extracting notches, there being.

shown in the present construction, two on each side of the hammer. For convenience, I will designate said notches by reference letters, and as all the notches are alike in structure and function, i only one need be' described in detail. The smallest notch is indicated at A, and the largest at B, on the claw member 6, in Fig. 1. In Fig. 2, I have shown notches. C and 1), tor inter: mediate sized nails. Thus, I equip the tool, for all sized nails used by a carpenter. v

Next referring toFig. 5, I will; describe the particular novel features of the nail pulling notch.

The nail E, is the largest size nail for which the tool is equipped to extract and the ill] IOU

material from which the nail has been partly extracted, is designated at F. The notch 13, has an inwardly disposed wall 23 and an outwardly disposed wall Q-l and a rear wall As will be seen from Fig. 3, the entrance or throat 26, is smaller than the base nearest wall this feature serving to prevent the nail from getting out of place, or the hammer from having relativemovement with respect to the nail. when the latter has once been engaged. Projecting from the inner wall 23, is a nail in'ipinging element which is shown to be in thet'orm of a ledge 27, which as shown in Fig. 3, is coincident with one dimension of the wall. Said ledge, as shown, has a sharpened edge which is intended to impinge the nail on one peripheral portion thereoi, and it will be noted that said ledge is disposed closely to the bottom of said notch B. Projecting from wall 24, is a companion ledge 28, which is likewise sharpened and which is adapted to engage an opposite peripheral. portion of the nail E. It will be noted that the extracting ledge 28, is-in converging relation to its .:ompanion ledge 27, and at a higher elevation in the notch. It-will also be noted that by recessing the members 6 and 7, as shown and described, I can dispose the notches and the ledges to advantage, leaving room for the nail to bend freely as it being finally extracted. The wall above ledge 27, need not recede as this wall is always moving away from the nail, but the upper portion of wall 24, above ledge 28, slightly recedes because it is moving toward the nail. Further, the ledge 53?, projects, as regards its transverse axis, at substantially right angles from the wall 23, whereas ledge 28, pro ects from wall Qel at a slight angle upwardly, as I clearly shown in Fig. By means of this construction, I am able to make a large size extracting notch function with a wide range of size of nail. Thus, in dotted lines, and as indicated at G, I have shown how this same largest size extracting notch will function to complete the extraction of the smallest size nail, and of course. it will be obvious how such notch would function to complete the extraction of nails of intermediate sizes. It the notch nearest the size nail is employed, the user can obtain a grip nearer the surface I than if a too large size notch is employed. However, with the range of sizes which I have provided, it will be clear that the user need not lose time in fitting the notch to the nail. The notches are so proportioned with respect to the ledges that at no time will the walls of the notch engage the nail being extracted. If the head of a nail has been mutilated, or if the nail has been broken oil, the device of my invention will function to complete the extraction of such mutilated nail which cannot be extracted by the use of the usual claw.

It will be noted that I have disposed the extracting notches as nearly as possible toard the tips oi the claw members so that after the main claw has been cnmloyed, the extracting notcl'ies can be brought into play and employment with the tips of the claw members near the surface so that the greatest possible amount ojlf service can be rendered in extracting the nail crunpletely from the material from which a partial extraction has been ellected by the main claw.

It is believed that the device of my invcntion will be fully undcrstmal from the fort goii'ig description and while I have herein shown one specilic form ot my invention, I do not wish to be limited thereto except for such limitations as the claims may import.

I claim:

l. A tool, for drawing nails having a claw formed of opposingly acting claw members, one oi said members having a ,at extracting notch, the opposing walls ol said notch having projecting nail impinging ledges for engagement with opposite peripheral portious oi the shank of the nail to complete extraction thereof when the tool is tilted on said claw and holding the nail free from the rolls of said notch.

A tool for drawing nails having a claw formed of curved claw members, one of said members having a nail extractii'ig notch pro vided with sharp projecting nail impinging ledges for ei'igagement with o mosite peripheral portions ol the shank of a nail, one oi. said elci'nents being disposed vertically in said notch above the other to hold the nail tree from the alls of said notch.

A tool for drawing nails and the like having a main claw formed oi? two claw members, one of said members increasing in thickness between its upper and rolling faces :l'rom its tip to its base, lllt' outer pow t'ion ol, the upper :t'acc of said member being recessed laterally inwardly from the outer face oi said member to form a. llange. said flange having a nail extracting notch extending thercthrough from the rolling face to the upper face of said llauge and said notch having smooth inward and outward and back walls. said inwiu'd and outward walls converging from said back wall to ward the outer face of said flange, said inward and outward walls each having a nail extracting ledge, and the ledge o'l said inward wall being close to the bottom of said notch and the ledge of said outward wall being locateifl mid-way of the height. oil? said notch.

In witness whereof, I have hereto set my
