UNITED STATES PATENT OFFICE,
JOHN F. TIN ER, OF UJALDE, TEXAS.
WR ENCH.No. 801,610.
To ((.7 l/whori t myi)l7/ 0one777?:
Be it known that I, JOiiN F. TINn, a citi-
zen of the United States, a resident of Uvalde,
in the county of Uvalde and State of Texas,
5 have made a certain new and useful Inven-
tion in Wrenches; and I declare the follow-
ing to be a full, clear, and exact description
of the same, such as will enable others skilled
in the art to which it appertains to make and
o use the invention, reference being had to the
accompanying drawings, and to letters or
figures of reference marked thereon, which
form a part of this specification.
Figure 1 is a side view of the wrench,
15 partly broken away, with the parts in nor-
mal position. Fig. 2 is a similar view with the
handle lever thrown out to release the teeth of
the dog from the teeth of the fixed jaw
shank. Fig. 3 is a similar view with the
20 handle lever closed toward the fixed jaw
shank. Fig. 4 is a side view of the wrench,
with the parts in normal position, the posi-
tions of the parts when the handle lever is
closed toward the fixed jaw shank being
25 shown in dotted lines. Fig. 5 is a detail sec-
tional view on a larger scale, with the parts
in normal position. Fig. 6 is a similar view
with the handle lever thrown outward to re-
lease the teeth of the pivoted clog from the
30 teeth of the fixed jaw shank. Fig. 7 is a
similar view with the handle lever closed
toward the fixe :jaw shank. Fig. is a de-
tail perspective view of the dog. Fig. 9 is a
similar view of the handle lever.
35 The invention has relation to wrenches of
that type wherein the movable jaw and its
operating lever are on opposite sides of the
shank of the main jaw, an it consists in the
novel construction "n1 combinations of
40 parts, as hereinafter set forth.
The object of the invention is to provide a
powerful wrench of simple construction,
wherein the movement for the operation of
the jaws is of slight degree, partially auto-
45 matic and easily effected.
In the accompanying drawings, the letter
a, designates the main jaw, and b, its shank,
which is straight, the jaw a, extending from
its end at right angles. The opposite side of
50 the shank b, from the jaw a, is provided with
a series of teeth c, at about its middle por-
tion. These teeth are incut, or set with
their outer ends even with the plane of the
side of the shank, so that the slide end of the
55 lever of the movable jaw will readily pass
over them when this jaw is being adjusted.Patented April 23, 1907.
The movable jaw d, is provided with a
short shank e, extending along the main
shank, and the adjacent sides of this short
shank and the main shank are smooth. The 6o
jaw d, extends at right angles to the short
shank, parallel to the main jaw. The mov-
able jaw is connected to the shank of the
main jaw by a broad loop f which is sufli-
ciently loose to allow the movable jaw to 6
rock a little.
'_he handle h, is recessed at its upper end
at k, and has, at its upper end portion, with-
in the inclosing side and back walls of such
recess, a (og k', provided with several teeth, 70
usually five or six on the side enext the main
shank. These teeth project from the inner
lateral surface ce, of the dog, as indicated at
'in, said lateral surface being rounded out-
ward to the upper end of the (og to provide 75
a rounded extension or slide end p, beyond
the teeth in. Thlie dog is pivoted to the in-
closing side walls of the handle lever inter-
mediately of the length of the (og at h and
so that its rear wall is near the rear wall or 80
bearing of the recess of the angle lever, but
sufficiently removed therefrom to allow a
little vibratory motion when the movable
jaw is reciprocated with relation to the fixed
jaw. 85
In the operation of this wrench, the action
for disengagement and readjustinent depends
upon the cnoit1ont operation, in connection
with the fixed jaw and movable jaw shantks, of
an angle lever, and a compound sliding and 9C
toothed (og pivoted to said angle lever at the
obtuse angle thereof, whereby the diseogage-
ment is effected directly by the pressure of the
lever on the slide end portion of the dog, in
conjunction with the pressure of the rounded 95
slide end of the dog against the fixed jaw
shank, forming a new tulcrum ilfor the handle
lever and dog at the point of pressure. The
readjusting reciprocatory movement is fa-
cilitated by the independent vibratory mo- oo
tion of the clog.
The end of the short shank of the movable
jaw is pivoted at s to cheek lugs gof the
handle lever h, said lugs embracing or strad-
tiling the main shank of the wrenc. The 105
pivot v is so located with respect to the ful-
crum pivot h2 that a line joining these two
points has an obtuse angle relation to the
handle end of the lever h of a)ont one hun-
drel and thirty five degrees. A spring s is 11
located between the movable jaw shank and
1 the main or fixed jaw shank, being shown asSpecification of Letters Patent.
