UNITED STATES PATENT OFFICE.

JOHN G. CANTLEBERY AN l) WILLIAM J. EDWARDS, OF HILLSVILLE, PENNSYLVANIA.

Specification of Letters Patent.

Patented May 22, 1906.

Application filed July 18, 1905. Serial No. 270,207.

To all whom it may concern:

Be it known that we, JOHN C. CANTLEBERY and WILLIAM J. EDWARDS, citizens of the United States, residing at'Hillsville, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Teeth for Steam-Shovels, of which the following is a Specification.

This invention relates to steam-shovels, and more particularly to a tooth for same which is provided with. a removable point.

In the operation of steam-shovels the teeth very quickly become worn and inefficient in operation, and much delay is commonly occasioned in replacing same.

The object of this invention is to produce a tooth for steam-shovels provided with a removable point which can be very quickly and easily replaced when worn.

With this object in view the invention consists, essentially, of a tooth formed in two sections which are connected by a joint the various parts of which interlock, so as to render it im ossible for same to work loose.

For a fiill description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawin s, in which Figure 1 is an un er side perspective view of a steam-shovel tooth embodying my invention. Fig. 2 is a longitudinal sectional view through the tooth. Fig. 3 is a sectional view on the line X X of Fig. 2. Fig. 4 is a detail perspective view of the parts.

Corresponding and like parts are referred to in the followin description and indicated in all the views 0 the drawings by the same reference characters.

The numeral 1 designates the main portion or the base of the tooth, which is provided with arms 2 and 3, by means of which it is adapted to be permanently secured to the shovel. The end of the base 1 is provided with an approximately rectangular recess 4, which extends through to one side of the base. The two opposite sides of this recess 4 are provided with longitudinal grooves 5. The point 6 of the tooth is provided with a tongue 7 ,which fits into the recess 4, virtually afiording a mortise-and-tenon connection, and is formed with ribs 8, which fit into the longitutongue 7, and the point 6 is provided with a similar extension 1 1, one side of which is flush with the opposite side of the tooth and which fits into a notch 12 in the base 1. The tongue 7 on the point 6 and the opposite sides of the recess 4 are provided with corresponding openings through which a screw 13 or other suitable fastening member is passed. The base 1 may be permanently attached to the shovel, and when the point becomes worn same can be quickly replaced by withdrawing the screw 13 and removing the old point. The ribs 8 on the tongue 7 cooperate with the longitudinal grooves 5 to form a very secure joint, and the extensions 9 and 11 serve the double function of preventing dirt from working into the joint and also of reinforcing same against lateral movement, so that it is ractically impossible for the joint to work oose.

Having thus described the invention, what is claimed as new is- 1. A tooth for steamshovels comprising a body and a removable point, the body being rovided with a mortise, a tenon projecting fiom the point and fitting into the mortise of the body, and interlocking recesses and extensions between the body and point at the upper and lower sides of the tooth.

2. A tooth for steam-shovels comprising a body provided with a mortise, a removable point having a tenon fitting into the mortise of the body, ribs formed longitudinall at opposite sides of-the tenon, the mortise aving grooves at opposite sides thereof to receive the ribs of the tenon, an extension projecting rearwardly from the point at its upper side, an extension projecting forwardly from the body at its under side, the body and point having recessed portions to receive the respective extensions aforesaid, and a transverse fastening passing through the body and the tenon and securing the same together.

3. A tooth for steam-shovels com rising a body portion adapted to be secure to the shovel, and a removable point for the tooth, said point and body portion being connected by an interlocking mortise and tenon. the
