L. R. BLAKE.
Improvement in Tacks.
No. 131,080. Patented sep.3,1872.
UNITED STATEs PATENT OEEICE.
LYMAN B. BLAKE, OF BROOKLYN, NEW YORK.
IMPROVEMENT lN TACKS.
Specification forming part of Letters Patent No. 131,080, dated September 3, 1872.
To all whom it may concern:
Be it known that I, LYMAN R. BLAKE, of Brooklyn, in the county of Kings and State of New York, have invented an Improved Lasting-Nail Blank; and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.
My invention relates to the construction of a nail-blank from which, in a suitable machine for driving the nails, Hat-headed nails or tacks may be eut one after another in regular snccession from the end of the blank 5 the particular object being to produce a blank for use with a device for lasting boots and shoes, and in which by the same action of the mechanism that drives the nail the nail to be driven is severed from the end of the blank. In my invention I roll a plate so that in cross-section it, is of T-shape, having a iiat straight undivided head or iiange and a toothed shankforming web, the teeth being comb-like, very acute angled, and joined at and only at their heads, and by the flat or fiat-topped head-forming piece, from which the teeth are integral projections, a nail being formed from the blank by separation of its head. The invention consists in this peculiar blank.
The drawing represents a blank embodying my invention, and a nail cut therefrom.
A shows the blank in front view. B is an end view of it. C is a top view of it. D shows the severed nail.
adenotes the head or head-piece, from which extend the shanks b, each shank being preferably a quadrangular pyramid, square in section, and the head being in cross-section dat on its top, thin edged at its opposite sides, and joined to the shank or t0othpiece by inclined faces.
In using the blank for lasting or nailing, I sever each head at the line of the angle between the two outer teeth, the head of the severed nail being square or rectangular in section. It is requisite that the nails should possess flat heads, and I obtain such heads by rolling the plate so that the outer face of each edge portion is straight and fiat.
With a nail-blank formed in accordance and described. LYMAN R. BLAKE.
