NITED STATES PATENT OFFICE.
J. HOGAN, OF ST. LOUIS, MISSOURI.
IMPROVEMENT IN NAIL-EXTRACTORS.
Specication 'forming part of LettersPatent No. 55,105, dated May 29, 1866.
To all whom t may concern:
Be it known that I, J. H. HOGAN, of the city and county of St. Louis, and State of Missouri, have invented a new Nail-Extractor, or instrument for drawing nails out of boXes and for other uses; and I do hereby declare that the following is afull and clear descript-ion thereof, reference being had to the accompanying draw- 1n gs.
Figure l ot the drawings represents a side elevation of the machine, and Fig. 2 is aplan ot' it.
To enable those skilled in the art to make and use my nail-extractor, I will proceed to describe its construction and operation.
It consists of a handle, A, made of cast-iron, the said handle being perforated by mortises at Al and A2. The mortise A is near the forward end of the lever, which at that point is made wider than any other part of it by the addition ofthe metal lug a, which forms a fulcrum for the handle or lever, as will be hereinafter more fully explained. There is a hard metal slide, BA, itted into the mortise A', so it can slide easily up and down. There is a slot, b, in this slide, through which the rivet b passes in such a manner as to hold it in the handle, but still to permit the slide to move up or down. There is also in the lower end of the slide a notch or groove, b2, as shown clearly by the red lines in Fig. 1, which represent the slide when it is down. The lower corners of the slide should be rounded or beveled off, as shown in Fig. 1, so they can be readily driven into the wood, for which purthen be ch an ged, so th at the teeth ofthe nippers p will embrace the headof the nail and the lug a will rest on the piece in which the nail is driven. Power will then he applied to the handle a? to raise it up, when it is evident the nippers will grasp the nail tight enough, by means of the handles of them sliding down in the mortise A2, to draw out any nail.
By increasing the size ot' the implement 'it might be made to take the place ot' the sha-ckelbar used at present for drawing spikes on railroads, bridgebuilding, Ste. The advantage of it consists in the safety attending its use, as both the nail or spike and the article from which the same is drawn are uninjured by the operation.
l prefer to make the slide B and the nippers O of steel, but this is by no means absolutely necessary.
What I claim is- Tho combination of the handle A, the slide B, and' the nippers G, substantially as described and set forth.
