SPECIFICATION forming part oi Letters Patent No. 309,414, dated December 16,1884.

- Application filed March 20, 1884. (No model.)

To all whom, it may concern Be it known that 1, JOHN W. G. SMITH, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Nails, of which the following is a full, clear, and exact description.

The object of my invention is to manufacture cheap and effective hob-nails; and the invention consists in casting said nails connected together in a particular way, and in the peculiar form of the nail itself.

Heretofore nails have been cast either singly or with their heads joined to form a continuous and unbroken sheet. To cast the nails singly consumes too much time in forming the molds, and to cast them with the heads joined in an unbroken and continuous sheet leaves the heads when broken apart ragged around their entire edge, so that considerable labor must be expended in finishing up said heads. Finally, hob-nails with but a single point work out of the leather when thelatter has been exposed to wear any length of time. To overcome these difficulties I cast the nails with their heads connected together only at certain points, leaving nearly the whole of the edges free. I thus avoid the necessity of at terward finishing up said edges. I also construct each nail with two points outwardly beveled at their ends, so that when driven into the leather said points clinch and remain firmly embedded.

In the accompanying drawin t, Figure 1 represents a perspective view of two rows of nails connected to an intermediate gate; Fig. 2, a top view of several rows of nails connected at the extreme corners of the head, and Fig. 3 a perspective view of a single nail.

Similar letters of reference indicate correspondin g parts throughout the different views.

A represents an ordinary gate, connected by ofifsets a with the heads of two rows of nails, 13. Said nails are provided with the ordinary thick beveled or conical heads Z), and have two points, 0. These points are situated at a greater or less distance apart, and have their extremities beveled outwardly in opposite directions. The function subserved by the bev eled extremities is to spread the points when the nail is driven into the leather. In Fig. 2 the nails are shown cast together without the intermediate gate and offsets. Thisis accomplished by casting said nails with their heads connected at the extreme corners.

It will be seen that in either of the above eases the nails, after being separated, have almost the whole of the edges of their heads smooth, and consequently require little or no finishing.

I am aware that hob-nails have been made with two shanks to one head; that the shanks have been tapered from the head to the point, and that they have been cast in sheets or groups with the edges or sides of the heads connected together; but

\Vhat I claim as new is- 1. A hob-nail having two opposite shanks beveled on the inside of the points in opposite directions, whereby said points may be spread divergent-ly, and thus be tightlyheld, substantially as described.

2. A group or sheet of east hob-nails connected only at their angular points or corners, substantially as and for the purpose specified.
