Specification of Letters Patent.

Patented J an. 12, 1915.

Application filed July 3, 1911. 8erial No. 633,643.

To all whom it may concern Be it known that I, WALTER E. ROBERTS, a citizen of the United States, residing at Allentown, in the county of Lehigh and State of Pennsylvania, have invented new and useful Improvements in Hobnails, of which the following is a specification.

My invention relates to nails and more particularly to the type which are called the hob-nails.

An object of my invention is to provide a hob-nail which is preferably adapted to be used in connection with shoe soles and one vhich will prevent the slipping of the wearer.

Another object is to provide a hob-nail which is of such construction as to enable the same to be driven with the tools which are now ordinarily used by mechanics.

A still further object of my invention is to provide a hob-nail which is simple in construction, efficient as a retaining means and one which is inexpensive to manufacture.

\Vith the foregoing and other objects in view my invention relates to such details of construction and in the arrangement and combination of parts as will be hereinafter fully described and specifically pointed out in the appended claims.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts, and in which Figure 1 is a side elevation of my hobnail. Fig. 2 is a. sectional view of my improved nail. Fig. 3 is a top plan view of my nail. Fig. 4 is a side elevation of my nail showing one end flattened as a rivet.

In the drawings I have shown my improved nail having a tapering shank 1 which is adapted to be driven into a suitable support such as thebottom portion of a shoe. Formed on one end of the shank are the offset portion 2 and enlarged head 3. The offset portion 2 is adapted to engage the shoe bottom or support after the shank has been driven into the same.

The wear-head or member 4: is adapted to be retained in the enlarged head 3 as clearly shown in Fig. 2 of the drawings, so that it projects beyond the lower portion of head 3, or in other words, is subjacent thereto when in use. The nail proper is preferably made of soft metal provided with a recess in its enlarged head, into which rewhereby it resists sliding of the shoe in.

material such as culm.

As stated, the nail proper is preferably made of soft metal. The wear-head i is made of a separate piece therefrom so that the same can be made of metal having a greater resistance to wear than the head 3. Said head l is preferably made of steel. By forming the head l of a metal that will resist wear more than the metal of the head 3, the latter will not wear away at its end when the person having a shoe provided with hob-nails constructed according to my invention, walks upon a hard surface such as stone.

As stated, the nail proper is preferably made of soft metal. The projecting member 4 is made of a separate piece therefrom so that the same can be made of a metal which will not wear as quickly as the metal of the nail proper, or more specifically its head. Said member 4 is preferably made of steel. By this construction of the pro jecting member being of a metal that will resist wear more than the metal of the head of the nail, the nail head will wear away. There will always be a projecting portion of the member 4, inasmuch as the nail head will wear away in excess of the extent to which the projecting member 4 will wear away.

It will also be seen that my nail may be used as a rivet as shown in Fig. 4.

From the foregoing it is made manifest that I provide a hob-nail which, having wear-head 4 will resist wear upon a hard surface such as stone, while the head 3, having considerable lateral surface, will resist sliding of the shoe it is carried by in fine condensed material such as culm, and hence, it may serve and enable miners to obtain a good foothold in and about mines where the material encountered is of such nature.

I desire it to be understood that slight changes in the construction may be resorted to without departing from the spirit of my invention, provided such changes fall within the scope of the subjoined claims.

Having thus fully described my invention,
