Specification of Letters Patent.

Patented Nov. 4: 1919.

Application filed March 25, 1919. Serial No. 284,947.

To all whom it may concern:

Be it known that I, ABE BOWMAN, a citizen of the United States, residing at the city of Long Beach, in the county of Los Angeles, State of California, have invented new and useful Improvements in Wrenches, of which the following is a specification.

My invention relates to ratchet-wrenches and the object thereof is to provide a wrench that can be operated in corners, and other places where there is but little room to move the handle, with as much efficiency as when there is perfect freedom for the operation of the Wrench. Another object is to provide a Wrench. with a removable and reversible nut socket, whereby the life of the main portions of the wrench is prolonged.

In the drawings forming a part of this application Figure 1 a view of my wrench showing the end of the nut socket, with a portion of the handle brokenaway, Fig. 2 is a View at right angles to Fig. 1, Fig. 3 is a side view of the nut socket detached from the other parts.

Referring to the drawings 5 is the nut socket which consists of a central circular hub 6 and reduced ends 7 and 8 which in outline may be said to be square with the corners cut ofi, but may be of other configuration. The socket has an aperture extending therethr-ough of a configuration in crosssection to fit the nuts that are to be turned by the wrench. In the drawings this aperture 9 is square. Upon the lower end 8 of the socket I detachably secure by screws 10 a ratchet collar 11 having in its upper end face radial ratchet teeth 12. Screws 10 pass through the collar and screw into threaded holes 13 in the lower end of the socket. The apertures in this collar fits end 8. Upon the hub 6 I mount a revoluble ratchet collar 14 which has radial ratchet teeth 15 in its lower end face which mesh with teeth 12 when the parts are assembled. Collar 1A has oppositely disposed trunnions l6 and 17 upon which the forked end 18 of handle 19 is mounted. One of the prongs of the handle is bifurcated and has a plug 20 secured therein by screw 21, shown in dotted lines in Fig. 2, so that the handle can be removed from the collar when desired. Upon the .upper end 7 of the socket is detachably secured a plain collar 22 by screws 23 which pass through the collar and screw into holes 24 in the upper end of the socket. Between collars 22 and 1A and surrounding hub 6 is spring 25 which normally holds collars 11 and 11 in contact. I make the fork of the handle sufficiently large to allow of a movement of the handle angularly to the socket when it is on a nut on a bolt, thereby enabling me to use the wrench on a nut in a corner or other close place.

By this construction I am able to reverse the nut socket when one end thereof becomes worn and restore the wrench to full operativeness. This wrench is particularly useful in ship building, as there are many positions in which it is almost impossible to use an ordinary wrench.

Having described my invention I claim 1. A wrench composed of a nut socket having an aperture therethrough adapted to fit over a nut, the ends of said socket being reduced and having a circular exterior intermediate the ends; collars mounted on said socket, one of said collars being revoluble thereon and the other removably secured upon one of the ends thereof, said collars having ratchet teeth in their opposed surfaces; trunnions secured to the revoluble collar; a forked handle mounted on said trunnions; a plain collar removably secured upon the other end of said socket; and a spring intermediate said last collar and said revoluble collar.

2. A wrench composed of a nut socket having a square aperture therethrough, said socket having reduced ends and an exterior circular center portion; a collar having ratchet teeth in one of its end faces and trunnions secured to opposite sides thereof revolubly mounted on the circular portion of said socket; a second collar having ratchet teeth in one of its end faces, said teeth being adapted to mesh with the teeth of the first collar, said second collar being detachably secured upon one of the ends of said socket; a third collar detachably secured upon the other end of said socket; a spring coiled around said socket between said last and first collars; and a forked handle mounted upon the trunnions of said first collar,

In witness that I claim the foregoing I have hereunto subscribed my name.
