EXTENSION HANDLE FOR WRENCHES A'NDOTHER-TOOLS.

"Application filed August 21, 1915-, Serial No. 318,924:- Rene'wed March 12, 1924.

To till whom it may concern.

Be it known that I, FRANK W. LOWNS- BER-Y, a citizen of the United States, residing at Scranton, Lackawanna County, in the State of Pennsylvania, have invented certain new and useful Improvements in Extension Handles for Wrenches and Other Tools, of which the following is a full, clear, and exact-specification.

My invention relates to improvements in supplemental or extension handles for wrenches, spanners, and other tools whereby to increase theleverage or power with which the tool is operated; and the same has for its object to provide a simple, efficient, and reliable handle which may be readily attached to and detached from a wrench or other tool.

Further, said invention has forv its object to provide a device of the character specified which is adapted for use in connection with tools having a flat or substantially flat handle or shank.

Further, said invention'has for its object to provide a device of the character specified which is adapted to receive the handle or shank of a tool, and to hold the same against accidental removal or detachment therefrom.

Further, said invention has for its object to provide a device of the character specified which may be made from an integral piece of metal.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends my invention consists in the novel details of construction, and in the combination, connection, and arrangement of parts hereinafter more fully described and then pointed out in the claims.

In the accompanying drawings showing an illustrative embodiment of my said invention,-

Figure 1 is a plan or top view showing an extension handle constructed according to and embodying my said invention, with a wrench in position thereon Fig. 2 is a side view thereof; and

Fig. 3 is an enlarged detail cross-section taken on the line 38 of Fig. 1.

In said drawings 10 designates the sup plemental or extension handle, which is preferably formed of an integral piece of metal, and comprises a fiat elongated handle or shank lliprovided at its outer or upper end with a fiat transverse member 1:2 which extends inwardly from one of the longitudinal edgesof the shank 11, across said shank, and has its free end terminating substantially in line with the opposite longitudinal edge of the shank. 13 denotes a similar member which is arranged a short distance in from the outer or upper end of the shank 11, and extends inwardly from the longitudinal edge of the shankopposite to that from which the member 12 extends. Both members 12, 13 are arrangedparallel with each other and in the same horizontal plane, but

above the plane of the surface of the shank 11, and have their free ends terminating substantially parallel and in line with their respective longitudinal edges of the shank 11. At one side of the shank 11 is provided a locking device for retaining the wrench or tool properly in position upon the extension handle 10. The said locking device comprises a small projection 14 which ex tends from the edge of the shank 11 having a circular socket 15 therein, and a reduced opening 16 in the base thereof. VVithin said socket 15 is disposed a stud 17 having a stem 18 extending therefrom and passing through thereduced opening 16 in the socket 15, and its outer end provided with a head 19. 2O denotes a spring arranged about the stem 18, intermediate the stud 17 and the base of the socket 15, which serves to maintain said stud 17 normally projected.

21 denotes a wrench whose intermediate or handle portion is engaged below the inwardly-extending transverse members 12,

18, and locked in position upon the extension handle 10 by the springpressed stud 17.

To remove the wrench 21 from the exforms or tools having handles or shanks. Havmg thus described my said invention,

" what I'claim and desire to secure by Let- I i a Wrench Or" other too-1,. substantially .as

tens Patent is 1% I l; Anext'ension handle for wrenches and analogous tools, comprising ashank'and a -'p-lurality of members formed integrally therewith and arranged in spaced relation to each other and said shank-,said members extending from f the opposite longitudinal edges of said shank transversely across the face-of said shank and adapted to receive specified.

to receive a tool, a socket provided in said shank 1n proximity to one of said transverse "members, a pin. located in said socket and ada-pted .to engage said tool, and spring means for maintaining said pin normally projected above the plane of said shank, substantially as specified. i I 3. An extension handle for Wrenches and analogous tools comprising a Hat shank, and a pair of members formed integrally with said shank and arranged in spaced relation thereon adjacent to one end thereof; said members extendinginwardly from the opposite longitudinal edges of said shank and adapted to receive a wrench or other tool, substantially as specified.

4-. An extension handle for Wrenches and analogous tools comprising a shank, a transversemember at one end thereof extending inwardly from one of the longitudinal edges of said shank, locking means provided along the same longitudinal edge of said shank, and a second member extending inwardly from the other longitudinal edge of said shank and arranged intermediate said firstnamed member-and said locking means, substantially as specified.

Signed at the city of Scranton, Lacka- Wanna County, in the State of Pennsylvania, this 21st day of July, one thousand nine hundred and, nineteen.
