IMPROVEMENT IN INSTRUMENT I'Olt DRAWING NAILS.

Be it known` that I, EDWARD P. WHITNEY, of Stamford, in the county of Faireld, and State of Connectiout, have invented a new and improved Instrument for Drawing Tacks, Nails, Spikes,`&c.; and Ido hereby declare that the following is a full, clear, und exact description of the same, reference being had to the accompunying drawing, forming part of this specica-tion, inwhich- Figure 1 is a side elevation of the instrument, the lower part thereof being shown in section.

Figure 2 is a plan o r top view thereof.

Figure 3 is an inverted plan view ofthe shoe and claw part of the claw-head.

My invention consists in the combination, with n. clawhead, of a footer shoe, the former being pivotcd,o1 so connected to the latter, that the requisite depression of the lever or handle, to draw the tack, can beeiected without the'heel ofthe claw-head resting upon the article into which the tack is driven, and hence the said articie is not marred bythe operation of drawing the tack.

A designates the claw-head, provided with a bifurcated forward end, a, as usual with tack-drawers, and b is the shank or lever for operating the said claw-head, provided, in the present instance, with a handle, c, (see iig. l.) But the handle @may be dispensed with, and a tack-hammer connected te the end ofthe shank instead thereof,'if desirable. y

B is a foot or shoe, to which the clawhead is pivoted. In the present instance the pivot passes through the side-walls ofthe shoe, and through. an eye in the claw-head, and holds the heel of the claw-head-elevated in the shoe, the-pivot being thev fulcrum' for the claw-head and shank. The bottom of the shoe has a smooth face, and its forward'end has a piece removed, as shown in fig. 3, and the claw-head isi-so shaped that the face or lower side of the claw 'a projects through this opening, and when the claw is in its normalcondition the said v lower face of the claw a is llush with the bottom of the shoe, thus placing the claw in a proper position to push it under the head of the tack, as will appear obvious by reference to igs. 1 and 3.

C is a ilat spring, having its upper end secured to the shank b, and its lewer'end curved, so as te bear upon the rear part of the shoe, the effect of which is to keep the lower face of the claw thrown down Hush with the bottom or lower face of the shoe. I will here remark that other styles of springs can be applied to effectl the saine end; for example, a spiral spring could be set in, so that its respective ends would bear against the shoe and the heel of the claw-head. And I will further remark that it is not absolutely essential that any spring he employed, asthe other parts would operate successfully without this feature.

I do not limit myself to the precise manner heroin shown, of pivoting the claw-head in the shoe, nor to the exact construction herein shown. The object accomplished by my invention is to so combine the claw-head and shoe (with or without a spring) that in drawing tacks, the heel of the claw-head shall not bear upon' the article intoi'which the tack is driven, and thereby greatly lessen the liability oi' marring such article, which often occurs when tack-drawers of the ordinary construction :irc used.

I have found this instrument especially adapted to drawing the tacks in carriage-tops, where there is great danger of scratching or marring the leather or other article with which the frame is covered, if an ordinary tack-drawer be employed, whose heel bears on the article and mars it when the handle is depressed `to draw the tack. With my invention, the flat face of the shoe rests. firmly on the article, and is not moved during the drawing of the tacit. The bifurcuted end of the claw-head being iush on the under sidc with the bottom face of the shoe, enables the claw to be readily inserted under the head of the tack or nail.

What I claim as my invention, und desire to secure by Letters Patent, is- 'I v 1. The combination of the claw-head A and shoe B, constructed and operated substantially as and for the purpose herein specied. I

` 2. A spring, C, in combination with the claw-head A 'and shoe B, substantially as and for the purpose specified. l
