GEORGE F. DGECOMB, 0F NORFOLK, VIRGINIA.

WRENCH.

Specification of Letters Patent.

Patented Oct. 12, 1920.

Application led March 16, 1920. Serial No. 366,188. i

T 0 aZZ whom it may concern Be it known that I, GEORGE F. EDGEooMB, citizen of the United States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented certain new. and useful Improvements in lVrenches, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in wrenches, and has for its object the consideration of a wrench that is made up of a minimum number of parts, and which is very easy and simple to operate, or adjust, to accommodate the work being operated upon.

With this and other objects in View, my

invention comprises certain novel constructions and arrangements of parts, as is `-illustrated in the accompanying drawing, and more particularly pointed out in the following description and the appended claim.

In the drawings:

Figure l is a view in side elevation of a wrench constructed in accordance with th present invention, while l Fig. 2 is an edge view of the wrench shown in Fig. 1.

Referring to the drawings by numerals,

1 designates the flat handle of the wrench,

pivotally mounted near one end of which and upon the large rivet 2 is a rotatable nut engaging disk 3. This nut engaging disk 3 is provided with nut receiving sockets 4, which sockets 4 vary in size, so that the wrench may be adapted torwork upon nuts of Vvarying sizes; these nut receiving sockets 4 are provided with parallel walls so as to tightly lt the parallel sides of a nut; between each two contiguous nut receiving sockets 4, and formed in the outer edge of the disk 3, is a tooth receiving socket 5 which socket 5 receives the tooth 6 of the pawl 7. The pawl 7 is pivotally mounted upon the large rivet 8, and said pawl comprises an enlarged body-portion 9, through which rivet 8 extends, and in the body portion 9 is a cut-away portion 10 that terminates in a flat face 11, that is engaged throughout its length by the straight sprlng 12; the spring 12 is held against the flat face 11 of the body means of a rivet 13.

The spring 12 engages near its outer end a fixed lug, or pin, 14 on the handle 1; the handle l5 of the pawl 7 projects beyond the edge of the handle 1, making it readily accessible to the operator to operate on handle 15 when desired for removing the tooth 6 from within the tooth socket 5, and thereby permit the disk 3 to be rotated until the nut on the work being worked upon, is placed in a nut socket 4, and then substantially square tooth 6 can be seated in a tooth socket; it is to be noted that the tooth sockets are Vprovided with parallel side walls so as to afford a more efficient receiving means for the parallel sides of the tooth 6, thereby producing a more substantial locking means for preventing accidental rotation of the disk 3 while a nut is being tightened orloosened.

vWhat I claim is:

In a wrench the combination, with a flat handle, of a disk pivotally mounted upon said handle near one end thereof, said disk 'provided in its edge with nut receiving sockportion of thev pawl by ets and with tooth receiving sockets, said sockets each being provided with parallel side walls, each tooth socket formed between each two contiguous nut receiving sockets, a pawl provided with a large body portion pivotally mounted upon one of the flat sides ofthe handle contiguous to the disk, said pawl providedwith a tooth having parallel sides, said tooth adapted to enter and fit snugly within any one of the tooth sockets, said body portion of the pawl provided with a straight flat portion forming on its edge, a flat spring resting against'the entire flat face and extending substantially longitudinal of the handle, fastening means securing the flat spring against the flat portion of the pawl, a pin or stop formed upon the handle and engaged by the outer portion of the flat spring, and a handle on said pawl and extending substantially parallel with the irst mentioned handle, substantially as shown and described.

In testimony whereof I hereunto aflix'my signature.
