Application December 12, 1945, y,Ser:ialnlo2 (c1. 145-1) Y 1.1Claim. l

This invention relates to a tool which is especially adapted for driving nails from old lumber.

An object of the invention is to provide a tool that will efficiently and quickly drive a nail from old lumber, that is composed of few simple and durable parts and can be manufactured at a low cost.

With the foregoing and other objects and advantages in view, the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawing in which:

Figure 1 is an elevational view of an embodiment of the invention, with the handle thereof partly in section.

Figure 2 is a sectional view on the line 2-2 of Figure l.

Figure 3 is a sectional View on the line 3--3 of Figure 2.

Figure 4 is a bottom plan View.

Figure 5 is a top plan view and Figure 6 is the same as Figure 3 showing the use of a smaller driving bar.

Referring more in detail to the drawing, the numeral I0 designates the octagonal bar or body of the tool which is provided with the tapered lower portion I2 having the reduced externally threaded portion I4 on the lower extreme end thereof.

The body is provided with the longitudinal central bore I6 and the longitudinal slot I8 communicating with the bore I6.

A driving bar 20 adapted to be mounted in the bore I6 has a threaded end 22 to receive the anvil 24 which extends outwardly of the body I0 through the slot I3. The bar tapers to the lower end, which is provided with the conical seat 26.

A nipple 28 is provided with an internally threaded bore 30 to be engaged with the end I2 of the body and a removable bushing 32 mounted in the bore 34 communicates with the bore 36.

A coil spring 36 mounted on the bar 20 has one end contacting the anvil 24 and one end contacting the bushing 32 thus maintaining the anvil 24 in full raised position, when the tool is not being used.

The nipple is provided with a tapering portion 36 merging into the flat sided portion 38 which is of a width to be inserted in the jaws of a claw hammer for tightening of the nipple on the body Il).

The lower end of the bore 34 is tapered to a feather edge at 40 to permit insertion under nails that have been bent onto the lumber.

A handle 42 having -a sectional wooden grip 44 secured thereto by rivets 46 is fastened to the upper end of the body by bolts 48.

The tool may, however, be provided with or without the handle Las may be desired.

In Figure 6 a smaller bushing 56 has been substituted for the bushing 32 and a smaller bar 52 has been substituted for the bar 20 thus the tool is adapted to be used for small or large nails.

When the tool is to be used for driving nails 54 from old lumber 56 the nails are received in the bushings and the point thereof is seated in the conical Seat 26 and when a hammer is used to move the bar outwardly of the body by blows on the anvil 24 the nail will be driven backward from the lumber. The diameter of the bar will be smaller than the diameter of the nail so that the bar can enter the hole made by the nail and einciently drive the nail out of the lumber. The nipple can be easily removed by the use of a claw hammer and the slot being open at the bottom the bars can be easily removed and replaced.

There has thus been provided a tool which will quickly and efficiently remove nails from old lumber and it is believed that the operation and construction thereof will be apparent to those skilled in the art.

It is also to be understood that changes in the details of construction, arrangement and combination of the various parts may be resorted to provided they fall within the spirit of the invention and the scope of the appended claim.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is.

A device of the character described for removing a nail from old lumber, comprising an octagonal shaped body having a tapered lower portion, a reduced externally threaded portion on the end of the tapered lower portion, a longitudinally extending centrally located bore in said body, a longitudinally extending slot in said body communicating with said bore, a driving bar slidably mounted in said bore, a tapered upper end portion on said bar, a conical seat in the lower end of said bar for engagement with the point of said nail, an anvil fixed to the upper end of said bar and extending outwardly of said body through said slot, said anvil adapted to be struck a blow which transmitted to said nail by said bar will drive the nail from the lumber, a nipple having a threaded bore at one end, said nipple being adapted to be mounted on the threaded end of said body, a centrally located bore in said nipple communicating with said threaded bore, a removable bushing in said latter centrally located bore and slidably receiving the 1owe1` end of said bar, a coiled spring mounted on said bar and engaging said anvil and said bushing and adapted to return said anvil to the full upper limit of the slot after said anvil has been struck by the hammer, the lower end of the nipple having a pair of flattened parallel sides to receive a Wrench for the tightening thereof and provided with a tapered or truncated cone-shaped end about the central bore to permit said nipple to be inserted under the head of a nail.
