EXTRLAGTOR FOB, PULLING HEADLE$S NAILS, SPIRES, AND THE LIKE.

Specification of Letters Patent.

A Patented Apr. 3, 1917.

Application filed December 12, 1916. Serial No. 136,486.

To all whom it may concern:

Be it known that I, Enoor-r HILL, a citizen of the United States, and resident of Dallas, Gregory county, State of South Dakota, have invented certain new and useful Improvements in Extractors for Pulling Headless Nails, Spikes, and the like, of which the following is a specification.

This invention relates to a tool for ex traoting headless nails, spikes and the like.

The novel features and advantages of the construction will be apparent from the following description taken in connection with the drawing which forms a part of this specification.

In the drawing,

Figure 1 is a perspective view of an eX- tractor embodying my invention, showing it in use;

Figs. 2 and 3 are top and side views of the extractor; and

Fig. 4 is a sectional view on the line 4-4 of Fig. 1, through the part of the extractor which is in engagement with a nail.

The extractor consists of a single length of bar steel which in the form shown is octagonal in shape and bent intermediate its ends to form a bend 10 near one end to provide a long arm 11 and a short arm 12. The long arm 11 constitutes the handle of the extractor and has a bend 13 which offsets the handle so that it will be disposed in a different plane from the short arm 12 which carries the fulcrum portion 101 and the claw portion of the device.

The claw is located at the outer end of the short arm 12 and consists of two wedgeshaped diverging fingers 14 and 15 having a V-shaped crotch 16 between them to receive different sized shanks of headless nails, such as the nail N. The opposed edges of the fingers 14 and 15, numbered 141 and 151 respectively, are tapered or sharpened so that they will bite into the shank of the nail to be extracted.

The bottom face 142 of the finger 14 is substantially fiat and tangent to the lower fulcrum portion 1010f the bend 10. The finger 15 extends upwardly at an angle of about 45 to the bottom face 142, the inclination upwardly starting at a point adjacent the apex of the V-shaped crotch 16. The fingers 14 and 15, and their edges 141 and 151 thus lie in different planes which intersect one another. Vertical planes through the arms 11 and 12 intersect one another approximately in the bend 10.

In order to extract a headless nail the tool is set in the position shown in Fig. 1. By pulling the outer part of the handle 11 upwardly in a vertical plane the tool will roll on the fulcrum portion 101, raising the claw fingers 14 and 15 and causing the edges 141 and 151 to bite into the nail N on opposite sides thereof. Due to the particular angular relations of the arms 11 and 12 and the fingers l4 and 15, the edges 141 and 151 will move slightly toward the left and right respectively, as viewed in Fig. 4. This movement of the fingers causes the edges thereof to bite into the nail at different heights and also bend the upper end of the shank over the finger 14 which gives the claw of the tool a secure hold on the headless nail. The claw portion of the tool will then withdraw the nail as the handle 11 is lifted. The bend 10 is of such a curvature that there will be a gradual and not an abrupt change of the fulcrum as the handle 11 is raised, and a steady pull will therefore be exerted on the nail being extracted. The cross sectional shape of the bar being approximately round also allows the fulcrum to move to one side slightly and gradually as the edges of the claw fingers bite into the nail. By having a gradual bend 10 instead of a sharp one the claw part may be gradually raised and the tool may also be twisted to one side to force the edges 141 and 151 more deeply into the nail andthereby obtain a better grip upon it.

While the tool has been described in detail it is to be understood that certain changes may be made therein without departing from the spirit of the invention.

Having thus described the invention what is claimed and desired to be secured by Letters Patent is:

1. An extractor for pulling headless nails, spikes and the like comprising a claw consisting of two diverging fingers disposed in diflerent planes, and a handle for said claw, said handle and claw being disposed in intersecting planes.

2. An extractor for pulling headless nails,

spikes and the like comprising a claw consisting of two diverging fingers having opposed biting edges, said fingers being in different planes, and means for raising the claw and causing said biting edges to bite into opposite sides of the shank of a headless nail to be extracted, substantially as described.

3. An extractor for pulling headless nails, spikes and the like comprising a bar bent upon itself intermediate its ends to provide a long arm constituting a handle, and a Copies of this patent may be obtained for 4. An extractor for pulling headless nails, spikes and the like comprising a bar bent upon itself nearer one end than the other to provide a long arm and a short arm, the

long arm constituting a handle for the tool and the bend joining said arms being of a gradual curvature and constituting the fulcrum portion of the tool, and a-claw at the end of the short arm consisting of two diverging fingers having opposed biting edges, 7

said fingers and the edges thereof being 111 different planes.

In testimony whereof I afiix my signature.

ENOCH HILL.
