UNITED STATES HORACE E. GEFFCKEN, OF DUBLIN, GEORGIA.

RATCHET-WRENCH.

Specification of Letters Patent.

Patented March 31, 1908.

Application filed May 17, 1907. serial No. 374,113.

To all whom it may concern.

Be it known that I, HORACE E. GEFFCKEN, a citizen of the United States, residing'at Dublin, in the county of Laurens and State of Georgia, have invented certain new and useful Improvements in Ratchet-Wrenches; and T do declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled. in the art to which it appertains to make and use the same.

This invention relates to an improved wrench. l

The object of the invention is to provide a wrench having a plurality of interchangeable nut caps and adapted for use either as a ratchet or solid wrench.

In the accompanying drawings, Figure 1 represents a side elevation of this improved wrench; Fig. 2 represents a longitudinal section thereof; Fig. 3 represents a transverse section through the head taken on line 3 3 of Fig. 1; Fig. 4 represents an end view of the wrench head; Fig. 5 represents a perspective view of the ratchet wheel detached; and' Fig. 6 represents a longitudinal section taken at right angles to the section shown in Fi .2.

Tn the embodiment illustrated, a wrench stock 1 is shown having a head 2 with spaced longitudinally-extending arms 3 and 4 forming a ratchet wheel receiving recess 5, said arms having alined openings as 6 extending transversely therethrough' and adapted to receive the ratchet barrel 7. This ratchet barrel 7 is of sufficient length to extend on opposite sides through the openings in the arms 3 and 4 and has a shoulder 8 which abuts against the outer face of the arm 3 and limits its longitudinal movement in one di rection.

A ratchet wheel 10 is arranged on the barrel 7 in the recess 5 between the arms 3 Ais fitted the corresponding angular shank of a nut engaging member or cap 15. This member 15 has a shoulder 16 atthe outer end thereof which abuts against the outer face of .ing on opposite sides the ratchet barrel 7 and limits its inward movement in said barrel. Opening from the recess 5 at opposite sides of the wrench are two slots or recesses 1.7 and 18 in which are pivoted

pawls

19 and 20 for engaging the oppositely pitched teeth of the two ratchetsections. Pivoted on the head 2 adjacent the slots are two lookinT members or

latches

21 and 22 for holding t ie pawls out of engagement with the teeth of the ratchet wheel when desired. Springs'as 20 are disposed under the outer ends of the

pawls

19 and 20 to hold their other ends normally in engagement with the ratchet teeth.

In the operation of this wrench, the nut engaging member or ca 15 having a socket of the desired size and s iape to iit the nut to be turned, is placed in the angular barrel opening and when engaged with the nut, the handle or stock is turned in either direction as desired to tighten or loosen the nut.

lWhen it is desired to use the wrench as a ratchet wrench, one of the latches as 21 or 22 is swung around over the rear end of the paw] adjacent thereto. and depresses it against the tension of its spring, thus holding it out of engagement with the ratchet wheel and permitting the other pawl to operate as is common in ordinary ratchet wrenches, it being understood that when both pawls are in engagement respectively with their sepa- Vrate sets of teeth, the ratchet head will b'e held against movement and devices transformed into a rigid wrench.

Having thus described my invention, what I claim as new is In a wrench, the combination with a stock provided witha head having spaced longitudinally extending arms integral therewith, said arms having alined openings passing transversely therethrough, a barrel mounted to rotate in the openings in said arms and having an angular opening extending longitudinally therethrough, said barrel project of the arms and havinor a shoulder at one end to limit its longitudina movement yin one direction, a collar detachably keyed to its other end to prevent movement thereof in the opposite direction, a nut engaging member having an angular shank to removably engage the opening in said barrel, a ratchet wheel mounted between said arms and detachably keyed to the barrel, said wheel having two peripheral rows of teeth fixed in reverse direction and separated by a smooth peripheral ridge, a pair of pawls mounted to lie between said arms in position In testimony whereof I have hereunto set to engage the respective rows of teeth, and a my hand in presence of two subscribing witpair of latches pivoted on either side of the nesses.
