To all whom'it may concern/.5 v I Be it -knownl that we, EDWIN J. EVANS and GEORGE E. HEMPHIL'L, citizens of the United States, residing at Salt Lake City,
' in the county of Salt Lake and State ,of
Utah, have invented certain new and useful Improvements in Monkey-Wrenches, of which the following'is a specification.
Our invention relates to wrenches, and has for its object to provide a simple monkey wrenchwhich may be adjusted to fit nuts of different sizes by new and novel adjusting means.
These objects we accomplishwith the device illustrated in the accompanying drawings in which similar numerals of reference indicate like parts throughout the several views, and as described in the specification forming a part of this application and pointed out in the appended claims.
In the drawings in which we have shown a substantial embodiment of our invention, Figure 1 is -a longitudinal section of the wrench in parallel with the planes of the jaws. Fig. 2 is an inverted plan view of the wrench, with the movable jaw and differential rod removed. Figs. 3, 4, 5, 6, and 7 are views in cross-section on lines 33, 44, 55, 6-6, and 77 of Fig. 1 respectively. Fig. 8 is a side elevation of the movable jaw and Fig. 9 is an endelevation of the same l We use the helical screw principal commonly used in certain screw drivers toadjust our movable j aw, and the invention consists in the combination of parts and construction of the helical screw changed to meet the requlrements of a monkey wrench,
and as shown in the drawings the shank 1 has an integral fixed jaw 2. The said shank and jaw are central1ybored, as as 3, to form a bearing for the differential rod, which rod has end bearings as'well. The said shank is slotted fromrend to end, as as 4, which slot opens to-the interior bore 3, and has a portion widened, as at 5,, to receive the guide flanges of the slidable jaw. The engaging shank'is given an ovoid form in cross sec v Specification of Letters Patent.
Patented se azo, 1921.
' tion to form thehandle ofthe wrench, and
onsaid handle is carried the operating sleeve 8. The said shank is int'eriorly recessed from theslot 5 to its end, and said recess extendsthrough the jaw 2'to form a guide race 9 within which the guide flanges ofthe movable jaw are operated. The movable jaw 10 has an integral'web portion 11 extending longitudinally toward the said sleeve .8, a
order that it will pass through said slot in assembling the parts of the wrench. The face of said portion 12 is transversely threaded, as at 13, to provide raised threads which engage in the helical groove 14 of the differential rod 6. The differential rod 6 has a helical groove 15 cut into its periphery from the bearing portion, which engages in the bearing nut 7, to near the end of said web portion 11 of the shank, with the pitch of the grooves about one inch to each convolution, also a helical groove 14 cut from the end of said groove 15 to the end of said rod, and whose pitch is much greater than the pitch of the groove 15, preferably about five convolutions to the inch. .A radially disposed pin 16 is fastened in saidsleeve 8 with but few parts which are assembled by in- H serting the portion 12 of the movable jaw through the said slot 5 into the recess '9, with the threads 13 engaging in the groove 14 of the rod 6, and when the .two jaws are contiguous the bearing nut 7 is screwed into place in the end of the shank 1. The sleeve 8 is then placed on the handle end of the shank and the pin 16 screwed into place with its inner. end engaged in the groove 15, when the wrench is ready for use. The jaw 10 is moved relative to the jaw 2 by slipping the sleeve 8 along the shank 1. The difference in the pitch of the grooves 14and 15- will allow a five or six inch movement of the sleeve while the jaw 10 will be moved only about one inch, thus providing the adjustment of the jaws by the rotation of the differential rod 6. V
Having thus described our invention we desire to secure by Letters Patent and claim- I 1. A monkey wrench comprising a longitudinally slotted andcentrally bored shank with a jaw integral therewith; a rod havin a helical groove out therein and of two di ferent pitches adapted to operate in the bore of said shank; a movable jaw; a flanged extension thereon vhaving its face vtrans-v versely threaded to engage in one portion of the groove ofsaid rod and with the :flanges engaginglthe edges of the slotted portion of saidsh'ank; a sleeve carried on said shank; and a fastened in said sleeve with itsend engaged in 'theother portion of said ;groove.
2. A monkey wrench comprising a longitudinally bored and slotted Shank and a fixed jaw in eg al therewith; and provided f S d spindle d. I
In testimony-whereof we have .afiixe'd oi' r flanged web on one edge which web extends beyond the nut engaging end of said jaw and the'whole web flange engaging in the guide recess of said shank and fixed jaw; threads cut'in the face of said flanged web portion of? said movable jaw; a sleeve. carried on said shank; and a pm ansaid sleeve havingone end engaged in one set -.of grooves V "EDWIN J. miss.
