GLAMP NAIL. No. 515,168.

NJTE STAT S PATENT FFICE CLAMP-NAIL'.
SPECIFICATION forming part of Letters Patent No. 515,168, dated February 20, 1894.
Application filed May 2,1893- Serial No. 472,756. (No model.)
To all whom it may concern:
Be it known that I, HENRY C. RASNER, a citizen of the United States, residing at San Francisco, in the County of San Francisco, State of California, have invented certain new and useful Improvements in Clamps or Dog-Nails; and I do declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same, reference being had to the letters of reference marked on the accompanying drawings, which form a part of this speoification.
My invention relates to clamp or dog nails.
The improvements consist in the following construction, the features will first be fully Set forth in detail, and the points of novelty then described and claimed.
Figure 1 represents a perspective View of one formof nail. Figl is a Cross-section of the material constituting the nail. Fig. 3 represents two sections of wood united by the application of my invention. Fig. 4 is a plan, and Fig. 5, a side elevation of a modified form of the invention.
In the drawings-A represents my improved clamp or nail. This clamp is provided essentially with a straight portion C at the junctnre of the sections to be united, from which project in opposite directions zigzag extensions D. The configuration of the opposite ends of these nails is such, when driven into the material which is to be united, that it serves to draw the sections together and hold them tightly in position.
The central straight portion C of the nail prevents the Splitting of the wood at the point of junction. It will be noticed in Fig. lthat the corrugations on one side of the part C are not parallel With those on the opposite side, but that the trend of the angles or ourves di- Verge from the top toward the bottom. In Other words the bottom or entering edge of the nail is wider or longer than the top. The effect of this construction is such that when driven into the meeting edges of two pieces of wood, the pieces are forced together by a wedge action, looking them firmly and tightly.
An important feature of my invention consists in fOrIning the first angle'on both sides of the straight portion C Sharp and pronounced, as clearly shown at G in Figs. 1 and 3 in order to present a well defined abutment next the part C on both sides to take the strain On the wood next the edges to be joined. Were the angles gradual, Or the ourve of the corrugation inward and slight at that point G, the effect would be to split the wood at its edges next the angle G, in most cases, as has been found in practice. In my invention this objection is entirely done away with.
I claim- A nail having a straight central portion and diverging corrugations On each side, and provided with overlapping lateral extensions, substantially as described.
In testimony whereof I affiX my Signature in presenee of two witnesses.
