Oct. 21, 1941. BURGER 2,259,611

DRILL Filed March 19, 1941 Inventor Attorney Patented Oct. 21, 1941 UNITED STATES PATENT qOFFlCE DRILL George M. Burger, Detroit, Mich.

Application March 19, 1941, Serial No. 384,189

4 Claims.

This invention relates broadly to drills and more particularly to a drill for drilling into steel and analogous metals.

The primary object of the present invention is to provide a drill having a removable point or tip to the end that when the tip or point becomes worn, it may be readily replaced with the result that maintenance of the drill at the proper length and with suitably conditioned points can be had with minimum cost and waste of time.

The invention, together with its objects and advantages, will be best understood from a study of the following description taken in connection with the accompanying drawing wherein:

Figure 1 is a fragmentary side elevational view of a drill embodying the features of the present invention.

Figure 2 is a side elevational View of the detachable point for the drill.

Figure 3 is a fragmentary side elevational view of the drill with the point removed.

Figure 4 is an end elevational view of the body portion of the drill, and viewing the same at the end thereof to which the point is attached.

Figure 5 is a fragmentary detail sectional view through the drill and point showing provision made to facilitate separation of the point from the body of the drill.

Figure 6 is a view similar to Figure 4 and illustrating a slightly modified form of the invention.

Referring more in detail to the drawing it will be seen that in the preferred embodiment thereof the drill, adjacent the working end thereof, is divided transversely in order to provide a main body section 5 and a detachable or removable point section 6.

At the end thereof to which the point 6 is attachable, the body section 5 of the drill is provided with male coupling elements which, as shown in Figure 4 and identified by the reference numerals l, are in the form of pins sub stantially triangular in end elevation, and as shown in Figure 6, and indicated by the reference numerals 8-8, are in the forms of pins that are cylindrical in end elevation.

To complement the fastening elements l-'! or 8-8, as the case may be, the point 6 at the end thereof to be detachably connected with the body 5 is provided with recesses or sockets 9-9 that will have a cross-sectional shape corresponding to the cross-sectional shape of the male coupling elements l-l and/or 8-8, as the case may be.

It is contemplated that in actual practice the male coupling elements 'l-l and/or 8-8 will have a driving fit in the sockets 9 so that in order to secure the point 6 to the body 5, all that is necessary is to place the point 6 on a soft metal surface and then, by applying force to the end of the body 5 remote from that end thereof to be coupled with the point 6, the coupling elements 1-1 and/or 8-8, as the case may be, are driven into the sockets 9, resulting in a positive securing of the point 6 to the body 5.

To facilitate separation of the point 6 and body 5, the body 5, at the end thereof to be coupled to the point 6, is provided with a transverse groove It] to accommodate a wedge pin l I as suggested in Figure 5.

Obviously to force the end 6 off of the body 5 the tapered end of the pin I l is inserted into the groove H] from one end thereof and a driving force applied to the pin II to cause the same to move transversely with respect to the axes of the body 5 and point 6. This, in an obvious manner, will result in the forcing of the parts 5 and 6 awayfrom one another and the consequent withdrawal of the fastening elements l-l and/or 8-8 from out of the sockets 9. Thus in a positive and efiicient manner may the point 6 be readily applied to the body 5, and similarly the point 6 removed, when worn or otherwise rendered useless, from the body 5 to be replaced by a point that is in good condition.

It is thought that the simplicity, as well as the many advantages of an invention of this character will be had by those skilled in the art without further detailed description.

While I have herein illustrated and described the preferred embodiment of the invention, it is to be understood that I claim all such forms of the invention to which I am entitled in view of the prior art and scope of the appended claims.

Having thus described the invention what is claimed as new is:

1. In a drill of the character described, a body, and a detachable point therefor; said body at one end thereof having a plurality of coupling pins projecting therefrom parallel to the axis of the body, and said point at one end thereof provided with sockets in which aid coupling pins have a driving fit for detachably securing the point to said body.

2. In a drill of the character described, a body, and a detachable point therefor; said body at one end thereof having a plurality of coupling pins projecting therefrom parallel to the axis of the body, and said point at one end thereof provided with sockets in which said coupling pins have a driving lit for detachably securing the point to said body; and said body at the end thereof to be detachably joined to said point being provided with a transverse groove to accommodate a wedge pin to facilitate the separation of the point from said body.

3. In a drill of the character described, a body, and a detachable point therefor; said body at one end thereof having a plurality of coupling pins projecting therefrom parallel to the axis of the body, and said point at one end thereof provided with sockets in which said coupling pins have a driving fit for detachably securing the point to said body; said pins being substantially triangular in cross section.

4. In a drill of the character described, a body, and a detachable point therefor; said body at one end thereof having a plurality of coupling pins projecting therefrom parallel to the axis of the body, and said point at one end thereof provided with sockets in which said coupling pins have a driving fit for detachably securing the point to said body, said pins being substantially cylindrical in cross-section.
