J. H. WILLIAMS. WRENCH. APPLICATION mu). MAY i. 1917.
ATTOH NEY Patented Apr. 20, 1920.
JAMES H. WILLIAMS, OF LEVERETT, MASSACHUSETTS.
WRENCH.
Specification of Letters Patent.
Patented Apr. 20, 1920.
Application filed May 1, 1917. Serial No. 165,779.
To all whom it may concern:
Be it known that I, JAMES H. WILLIAMS, a citizen of the United States, residing at Leverett, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.
This invention relates to certain new and useful improvements in wrenches.
The primary object of the invention is to provide a wrench which may be quickly adjusted to fit the nut to which it is to be applied.
Another object of the invention is to provide a wrench so constructed that the force exerted on the handle in turning the nut will be communicated to the aw members in such a manner that the pressure of the latter upon the nut will be increased in proportion to the resistance ofi'ered by the nut.
A further object of the invention is to provide a wrench having an outer jaw of peculiar construction which is adapted to grip the smallest size nut.
The above and other objects will be more readily understood from the following description and drawings in which draw- 1ngs:
Figure 1 is a side elevational view of my improved wrench.
Fig. 2 is an edge view and Fig. 3 is a view similar to Fig. 2, looking in the opposite direction.
In the drawings wherein is illustrated the preferred form of my invention the numeral 1 indicates a handle which is round ed in cross section and has one end extended to provide the flattened and clownwardly curved shank 2, the latter being equipped on its upper surface with the curved jaw face 3. The outer jaw, as indicated at 4 is also curved and is equipped with a forked shank 5 which embraces the inner jaw 2 at a point adjacent the handle 1 and is adapted to be pivotally secured thereto by any suitable means such as the pivot bolt 6. The outer jaw 4: is provided with a plurality of jaw faces as indicated at 7 and 8 respectively, the face 7 being formed on the inner edge of the free end of said jaw and the face 8 being formed on the lower edge of the shank 5. The jaw 4 is further provided with a nut engaging shoulder 9 arrangedbetween the jaw faces 7 and 8 and adapted for cooperation therewith. Cooperation between the shoulder 9 and the jaw faces 7 and 8, as will be hereinafter explained, is attained by forming the said shoulder with straight sides 10 and 11, the side 10 thereof being arranged to extend at right angle to the jaw face 7 and the side 11 being similarly arranged with respect to the jaw face 8.
In the ordinary use of my improved wrench, the nut to be removed or applied, is clamped between the jaw face 7 and the inner jaw 2, in this instance the side 10 of the shoulder 9 cooperates with the face 7 to hold the nut stationary between the aws 2 and 4:. When, however, the wrench is to be applied to a nut which is too small to be conveniently clamped between the face 7 and the jaw 2, the nut is-adapted to be received between the side 11 of the shoulder 9 and the jaw 2. In this manner it will be seen that even the smaller sized nut can be firmly clamped against the face 8 of the shank 5, the adjacent side of the shoulder 9 and the inner jaw face 3.
Having thus fully described my invention, I wish it to be understood that I do not limit myself to the preferred form shown but may make such changes in construction and arrangement of the parts as may come within the scope of the invention.
What I claim is A wrench comprising a shank provided with a smooth cam head jaw, a loosely swinging complementary jaw pivotally mounted thereon provided with a plurality of steps providing angular recesses adapted to receive and embrace the corner of the nut to seat varying sized nuts.
In testimony whereof I affix my signature in presence of two witnesses.
JAMES H. WILLIAMS.

CHARLES L. PUTNEI, FRANK A. GLAZIER.
