EDWIN LE ROY ANTONY, OF CAMERON, TEXAS.
SPECIFICATION forming part of Letters Patent No. 596,235, dated December 28, 1897.
Application filed June 28, 1897. Serial No, 642,601. (No model.)
To all whom it imay concern:
Be it known that I, EDWIN LE ROY ANTONY,
a citizen of the United States. and a resident
of Cameron, in the county of Milam, State of
5 Texas, have invented a certain new and useful
improvement in the means used in adjusting
the clamping-jaws of wrenches to nuts or taps
to be screwed on or off their bolts or holdings;
and I do hereby declare the following to be a
10 full, clear, and exact description of the inven-
tion, such as will enable others skilled in the
art to which it appertains to make and use the
same, reference being had to the accompany-
ing drawings, making a part of this specifica-
15 tion, and to the letters of reference marked
thereon, and in which similar letters of refer-
ence indicate corresponding parts.
My invention relates to improvements in
monkey-wrenches; and its object is to pro-
20 vide an improved construction of the same
whereby the clamping-jaws may be quickly
and readily adjusted to the nut or tap which
is to be engaged thereby.
The invention consists in the novel con-
25 struction and combination of parts herein-
after described and claimed.
In the accompanying drawings, Figure 1 is
a side elevation of a wrench constructed in
accordance with my invention. Fig. 2 is a
30 side elevation of the handle or frame. Fig.
3 is a similar view of the movable jaw and
its shank. Fig. 4 is a vertical section on the
line z z, Fig. 1. Fig. 5 is a similar section on
the line x x. Fig. 6 is a detail view of the
35 ratchet-catch. Fig. 7 is a detail view of the
sleeve-blank before being bent into form.
Fig. S is an end view of the sleeve. Fig. 9 is
a detail view of the handle or frame, looking
from the under side and showing the holes in
40 which the pins of the catch work.
In the said drawings the reference-letter F
designates a frame or handle made of metal
and comprising the arms n n, connected to-
gether at one end, and one of said arms at the
45 opposite end being formed with a stationary
jaw k. Said arm is also formed with an en-
largement y at the opposite end. There is
a space between said arms to receive a mov-
able shank T, cut away at the inner end,
5o forming a reduced portion T', having upon
one edge a number of rack-teeth y2 and at
the outer end formed with a head H and a
jaw k', movable with the shank. The object
of the enlargement y is to form a contracted
space to receive the reduced end T' of the 55
The letter J designates a sleeve consisting
of a metal plate bent over near the center,
forming two parallel portions a a, which em-
brace the arms n n. This sleeve is formed 6o
with holes h, through which and also through
holes h' in one of the arms n pass bolts or
rivets r, by which the sleeve is firmly secured
to the handle or frame At one end said
sleeve is formed with lugs o, with which en- 65
gage lugs e on a catch or rack-plate C, formed
with teeth t, adapted to engage with the teeth
on the shank T. This plate is located in a
recess b in one of the arms n and is provided
with pins p, passing through holes m in the 7o
arm. Coiled springs S are interposed be-
tween said catch and the arm to throw the
former into engagement with the teeth of the
shank. The purpose of the lugs e and o is to
prevent the rack-plate C from being forced 75
out of its seat by the coiled springs S should
the shank T be entirely withdrawn from the
handle, the lugs e in such case engaging with
or abutting against the lugs o.
In use the coiled springs will force the catch 8o
or rack-plate into engagement with the teeth
of the shank of the movable jaw, thus hold-
ing the latter in place. To adjust the mov-
able jaw,the said catch or rack-plate is pushed
away from the shank, so as to disengage its 85
teeth therefrom,when the shank can be moved
out in a rapid manner. The catch is then re-
leased, when the coiled springs will again force
the catch or rack-plate into engagement with
the shank and, sliding easily over each other 90
inwardly, the adjustment is quickly made to
a nut or bolt by pressing the head H and the
handle toward each other, holding over the
nut or bolt, thus clasping it between jaws
k k' by the engagement of the teeth of the 95
catch or rack-plate with the shank-teeth au-
Having now fully described my invention,
what I claim as new, and desire to secure by
Letters Patent, is- 100
1. In a wrench, the combination with the
frame or handle comprising the connected
arms, one of which is formed with a jaw, a re-
cess and an enlarged portion, and the sleeve
