ADOLPH E. AESCHLIMANN, OF TAYLOR, TEXAS, ASSIGNOR OF ONE-THIRD TO M. F. KLATTEN-
HOFF AND ONE-THIRD TO JOHN F. SCHRIEVER, BOTH OF TAYLOR, TEXAS.
WRENCH.No. 904,468.
Specification of Letters Patent.
Application filed May 19, 1908. Serial No. 433,785.To all whom it may concern:
Be it known that I, AnOLPH E. AEsciLI-
MANN, a citizen of the United States, resid-
ing at Taylor, in the county of Williamson
5 and State of Texas, have invented certain
new and useful Improvements in Wrenches;
and I do hereby declare the following to be
a full, clear, and exact description of the
invention, such as will enable others skilled
10 in the art to which it appertains to make
and use the same.
This invention relates to new and useful
improvements in wrenches and has relation
more particularly to that class of wrenches
15 known as sliding adjustment.
It is an object of the invention to provide
a novel device of this character which can
be readily employed either as a nut wrench
or a pipe wrench.
20 It is also an object of the invention to pro-
vide a novel device of this character con-
prising a hollow stationary member and a
movable member projecting therein, said
movable member having a movement later-
25 ally of the hollow member to increase the
gripping action of the jaws carried by both
of the members when strain is made on the
members in one direction.
It is also an object of the invention to
30 provide a novel device of this character con-
sisting of a hollow stationary member and
a movable member projecting within said
hollow member, the hollow member having
rotatably mounted thereon an adjusting
35 member engaging an end of the movable
member.
It is also an object of the invention to
provide a novel device of this character
which will be simple in construction, ef-
40 ficient and advantageous in practice and
comparatively inexpensive to manufacture.
With the above and other objects in view,
the invention consists of the details of con-
struction and in the novel arrangement and
45 combination of parts to be hereinafter more
particularly referred to.
In describing the invention in detail, ref-
erence will be had to the accompanying
drawings forming part of this specification
50 wherein like characters of reference denote
corresponding parts in the several views and
in which,
Figure 1 is a view in side elevation of the
invention, and, Fig. 2 is a view partly inPatented Nov. 17, 1908.
section and partly in elevation illustrating 55
the various details of the invention.
In the drawings, 1 denotes the stationary
member formed of any desired material ter-
'minating at one end in the jaw 2. This
member 1 is hollow and has its front edge 60
inclined downwardly from the jaw 2 to its
opposite end as is fully shown in Fig. 2.
The end of the member 1 opposed to the jaw
2 is provided with the approximately right-
angular flange 4 which is adapted to pro- 65
ject within a runway 5 in a knob 6. This
runway may be formed in any desired man-
ner but it has been found best in practice
that initially the knob be provided with an
upstanding annular flange which when ap- 70
plied to the member 1 is upset about the
flange 4. This knob is free to rotate around
the member 1 and is provided with a pro-
jected portion or shank 7 extending within
the lower portion of the member 1. The 75
knob and its shank 7 is provided with a
longitudinally disposed recess S. The upper
portion of the recess 8 is reduced in diameter
and screw-threaded as at 9. This threaded
portion of the recess is engaged by the 80
threaded lower end 10 of the movable mem-
ber 11 which is formed of a solid piece of
material and projects within the hollow
member 1 and is of less width than the hol-
low member 1. The upper end of the mov- 85
able member 11 terminates in the jaw 12
arranged above the jaw 2 hereinbefore re-
ferred to.
It is thought to be apparent when it is
desired to adjust the jaw 12 with relation to 90
the jaw 2, it is only necessary to rotate the
knob 6 in the desired direction. Normally
the member 11 is held in contact with the
straight rear wall of the member 1 by a
flat spring 13 which has one end secured to 95
the inclined portion of the jaw 2 and its
opposite end bearing against the member 11.
It is thought to be apparent that when the
jaws 2 and 12 are caused to contact with an
article, more especially a pipe and a forward 100
pull is given to the stationary member 1, the
inclined face 3 of the stationary member 1
will permit sufficient movement of the sta-
tionary member 1 independent of the mem-
ber 11 as to greatly enhance the gripping of 105
the jaws 2 and 12. It might also be well to
state further that the opposed faces of the
jaws 2 and 12 are toothed or serrated.
