COMPLETE SPECIFICATION.
Improvements in Wrenches.
1, JERRY FOLEY, of Number 28 Sullivan Street, in the City of Syracuse,
County of Onondaga and State of New York Contractor, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :—
My invention relates to improvements in wrenches, and has for its object the
production of a practical and effective construction in which one of the clamping
jaws moves towards the other with a maximum degree of rapidity, and firmly
and positively clamps the article interposed between said jaws; and to this end
it consists, essentially, in the general construction and arrangement of the parts, all
as hereinafter more particularly described and pointed out in the claims.
In describing this invention, reference is had to the accompanying drawing,
forming a part of this Specification, in which, like letters indicate corresponding
parts in all the views.
Figure 1 is an elevation of my improved wrench, its movable jaw being shown as
somewhat separated from the jaw provided upon the bar or shank.
Figures 2 and 3 are transverse vertical sectional views, taken on lines 2-2
and 3-3, Figure 1.
Figure 4 is a longitudinal vertical sectional view, taken on line 4-4, Figure 3.
Figure 5 is a vertical sectional view of the detached movable jaw, taken on
line 5-5, Figure 2, and
Figure 6 is a transverse vertical sectional view taken on line 6-6, Figure 5.
A is a bar or shank provided at one end with a clamping jaw a and at the other
with a hand engaging portion a¹. This bar or shank A is formed with a cut out or
groove a in one face thereof, and with a projecting lug a³ arranged at one side of
the groove or cut out and having a groove or cut out at extending inwardly from
its outer face. The lug a³ is preferably formed separable from the shank A-in
order to facilitate the ready assemblage of the parts of my invention, and is conse-
quently formed with a central aperture a' and the extremity of the shank A
unprovided with the jaw a is reduced in diameter and is passed through the
aperture a. The extreme end of said reduced extremity of the shank A extends
beyond the corresponding end of the hand engaging portion a¹ and is secured to a
suitable cap or shoulder a".
B is a second clamping jaw, movable lengthwise of the bar or shank A, and
preferably provided with separate ears b, having openings in corresponding
extremities for receiving the bar or shank A and guiding said jaw in its movement.
These ears b, bare connected together at their opposite extremities by a barrel t
which is formed with a lengthwise socket or guide way ³ provided with lengthwise
oppositely arranged series of shoulders or threads and lengthwise grooves b³ to
interposed between the adjacent edges of said shoulders.
C is a spindle having one end journalled in the lug or arm a and the other
mounted in the socket 3 and provided with lengthwise oppositely arranged
series of shoulders or threads e, formed with pointed extremities c¹ and movable
into engagement with the corresponding shoulders or threads of the socket or
guide way or out of engagement with said shoulder into the grooves &³ ³.
C is an engaging shoulder upon the spindle C for enabling the user to rock said
spindle and force the shoulders or threads e thereou into or out of engagement
with the corresponding shoulders of the movable jaw B for clamping said movable
jaw B against the article engaged by the wrench or permitting of the rapid
lengthwise movement of said jaw along the bar or shank A without retardment by

page_text: the engaging shoulders or threads of said spindle. This shoulder C is aligned
with the cut out or groove a in the shank A, and, as clearly seen at Figures 1
and 4, said groove or cut out is of greater width than the thickness of said shoulder
for permitting the shoulder to move lengthwisely within said groove as the spindle C
is correspondingly moved.
D. D are stop shoulders for engaging the opposite faces of the bar or shank A
and limiting the rocking movement of the spindle C, and, as preferably constructed,
these shoulders consist of the opposite projecting ends of a bar extending through
the shoulders C¹.
E is an adjuster or nut mounted within the cut out or groove u upon the rear
end of the spindle C, which is of less diameter than said spindle and is provided
with serew threads . By means of the adjuster or nut E the spindle C, after its
shoulder C has been rocked to the limit of its movement can be forced length-
wisely from additionally clamping the article engaged by the jaw, and, as previously
stated, the shoulder C does not prevent said lengthwise movement of the spindle C
as the cut out or slot a² is of greater width than the thickness of said shoulder.
It will be readily apparent to one skilled in the art that the movable jaw of my
improved wrench is adjusted with great rapidity to the approximate separation
from the opposite jaw; that when so adjusted the shoulders of the spindle Care
readily engaged with the corresponding shoulders of said jaw, and serve to force
the same towards the former jaw a limited distance, and that, if the article engaged
by the wrench is not sufficiently clamped by its jaws, the nut E may be operated
to additionally clamp said article.
My invention is economically manufactured, and is, as is evident, simple, practical,
and effective.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. In a wrench, the combination of a shank A provided at one end with a fixed
jaw a and having a projecting arm a³ and a cut out a² interposed between the jaw a
and the arm as in proximity to said arm a³, a jaw B supported upon and movable
lengthwise of the shauk A between the jaw a and the arm a³ and provided with a
socket 3 closed at one end and extending inwardly from the opposite face of the
jaw B and having a series of engaging shoulders and a groove b, a spindle C
having one end journalled in the arm us and the other end arranged within the
socket and provided with a series of shoulders e for engaging the shoulders
and registering with the groove b, a shoulder C¹ of greater diameter than the
spindle C fixed thereto and projecting within the cut out a², and oppositely arranged
stop shoulders D, D for engaging the opposite faces of the shank A consisting of
the projecting ends of a pin passed through the shoulders C', substantially as and
for the purpose set forth.
2. In a wrench, the combination of a shank A provided at one end with a fixed
jaw a and having a projecting arm a³ and a cut out a² interposed between the jaw
and the arm a in proximity to said arm a³, a jaw B supported upon and movable
lengthwise of the shank A between the jaw a and the arm and provided with a
socket 3 closed at one end and extending inwardly from the opposite face of the
jaw B and having a series of engaging shoulders and a groove 6, a spindle C
having one end journalled in the arm a³ and the other end arranged within the
socket and provided with a scries of shoulders e for engaging the shoulders
and registering with the groove, said shoulders e having at corresponding ends
pointed engaging extremities e¹, a shoulder C' of greater diameter than the spindle C
fixed thereto and projecting within the cut out a², and oppositely arranged stop
shoulders D, D for engaging the opposite faces of the shank A, substantially as
and for the purpose specified.
3. In a wrench, the combination of a shank A provided at one end with a fixed
jaw a and having a projecting arm a³ provided with a cut out a extending inwardly

page_text: from its outer face, and a cut out a² interposed between the jaw a and the arm a
in proximity to said arm a³, a jaw B supported upon and movable lengthwise of
the shank A between the jaw a and the arm a³ and provided with a socket 6³ closed
at one end and extending inwardly from the opposite face of the jaw B and having
a series of engaging shoulders 64 and a groove bb, a spindle Ċ having one end
journalled in the arm a³ and formed of less diameter than the spindle C and provided
with screw threads, and the other end arranged within the socket 6³ provided
with a series of shoulders c for engaging the shoulders and registering with the
groove b, a shoulder C' of greater diameter than the spindle C fixed thereto and
projecting within the cut out a* and formed of less width than the width of said
cut out, a stop shoulder D for engaging the shank A, and an adjusting nut E
mounted upon the screw threaded extremity of said spindle C and arranged within
the cut out a whereby said spindle C and jaw B may be lengthwisely adjusted,
substantially as and for the purpose set forth.
