FLUID-OPERATED DRILL .AND HANDLE .LHEREFOR.

Specification of Letters Patent.
Application filed June 14, 1912.
Patented Aug. 4, 1914:.
Serial No. 703,765.
in the county of Bradford and State of Pennsylvania, have invented certain new'and useful Improvements in Fluid-Operated Drills and Handles Therefor, of which the following is a specification.
This invention relates to fluid operated drills of the type used for drilling holes in close proximity to walls or in other positions where the space is limited in one or nioredirections and more particularly to a drill of this type which is provided with an additional handle which can be removably secured to it enabling it to be used for general drilling purposes.
Drills of this type such as shown in my copending application Serial 703763, filed June 14th, 1912 are necessarily long and narrow on account of the restricted places in which they must be used and are provided with but a single handle which projects from the end of the tool opposite to the drill spindle; It is therefore almost impossible to use such a drillin any situation where the feed screw can notbe brought into op- Furthermcre as the drill spindle must be at the extreme limit of the drill casing in one direction} at least, and in practice usually as close as possible to the outszde of the casing in three directions to enable the drill to be used in restricted passriggcs closed at one end, it is not feasible to secure'a handle to the drill itself by bolts or screws with sufficient strength unless the size of the casing is materially increased beduce a drill and a handle of such construc-- tion that the handle may be firmly secured to the drill without interfering with its operation when it is desired to usc it for ordinary drilling work and which can be easily removed when it is desired to use the drill for special work in drilling in corners and restricted space for which its construction is particularly adapted.
lVith this object in view I have devised a drill and a handle therefor. a practical embodiment of which i shown in the accompanying drawings in which Figure l is a side elevation of the drill with handle attached Fig. :2 is a plan view of the spindle end of the drill with the handle in position and Fig. 3 is a side elevation of the handle un-attachcd to the drill.
The drill as shown comprises a casing 1 at one end of which is secured a handle 2 and at the other end of which is a drill spindle bearing sleeve 3. The internal construction of the drill forms no part of the present invention and is fully described in my copending application, mentioned above. The spindle bearing sleeve extends upwardly and downwardly from the drill casing forming opposite cylindrical projections t and The handle consists of a saddle piece (3 fitting; over the end of the drilh This saddle piece is provided at its lower end with a collar 7 which fits over the cylindrical projection and at its upper end with a similar collar composed partly of the saddle piece itself and partly of a semicylindrical retaining piece 8 which is adapted to he's-ccured to the saddle piece 6 by bolts 9 which pass through projecting lugs 10 on the retaining piece and the saddle piece. Secured to the saddle piece 6 is a handle grip 11 which may be of any desired shape.
Tn operation: when it is desired to use the drill for ordinary purposes the collar 7 is slid over the lowerprojection 5 and the re tainina piece 8 bolted to the upper part of the saddle piece (3 around the upper projec-' tion l thus fastening the handle firmly and securely to the drill thereby enabling at single drill to be used for all purposes, which has heretofore not been possible on account of the necessary construction of the drills used for work in restricted places.
It is. to be understood that the present showingand description discloses only one specified modification oi my invention and other forms and modifications are include i y in the spirit and scope of the invention as expressed in the claims.
\Vhat I claim is:
1. The combination with a drilling machine comprising an plongated casing having a. spindle hearing at one end, a handle secured to the other end, and handle holding projections on the casing coaxial Wit-11' the spindle, of a second handle removably secured on said handle holding'projections.
2. The combination. with a drilling machine comprising an elongated casing With a spindle hearing at one end and a handle secured to the other end, said spindle hearing having ends projecting from said casing, of a second handle having fastening means removably secured on said projecting spindle ends. 7 I
3. The combination With a drilling ma.- chine comprising an elongated casing adapted foreclose corner Work, a spindle bearing ing at one end of the casing having ends projecting from said casing, and a fixed handle on the other end, of a handle compiece reiro'vably secured to the other end of said saddle piece forming a second collar,v and a handle grip on said saddle piece;
