jPECIFICATION forming part of Letters Patent No. 308,786, dated December 2, 1884.
Application filed 2May 24, 1884. M lodel.)To cdlZ71 one it 7)7aZ c7cer7.:
Be it known that I, ;ILLIAMI S. MORRISON,
of Fort Worth, in the county of Tarrant and
State of Texas, have invented a new and Im-
5 proved Pipe-Wrench, of which the following
is a full, clear, and exact description.
This invention consists of a pipe-wrench
comprising a bar having a hook-ended arm
pivotally connected to said bar, and certain
o0 details in the construction of said parts, sub-
stantially as hereinafter more fully set forth,
and pointed ont in the claims.
Reference is to be had to the accompanying
drawings, forming a part of this specification,
15 in which similar letters of reference indicate
corresponding parts in all the figures.
Figure 1 is a side elevation of the pipe-
wrench. Fig. 2 is an end elevation of the
same, and Fig. 3 shows the bar as used for ex-
20 treating spikes.
A is the handle-bar of the wrenchhaving a
foot, a, of curved form, and slotted to receive
the arm. B3 is the arm held in the slot of the
bar by a pivot-pin, b, that is held by a spring-
25 catch, c, which allows ready removal of the
pin. The arm B has both ends formed hook-
shaped--one being larger than the other-and
is made with three or more holes for the pivot-
pin, so that the end in use can be set nearer
30 to and farther from the serrated end of the
foot a. The arm is to be reversed end for end,
according to the size of pipe, and this double-
ended arm, with its endwise adjustment, adapts
the wrench for a large range of work. The
35 tool always relieves itself from the pipe as
soon as pressure is slackened.Pipe-fitters usually need to carry separate
chisel-barsand nail-drawers. I savethe extra
weight and expense by forming the outer end,
d, of the bar A tapered, so as to serve as a 40
chisel-bar, or as a screw-driver with a small
wrench, and the curved end of the foot a is
made with a notch, e, so that the bar can be
used for drawing spikes and nails. The man-
ner of using the bar as an extractor is shown 45
in Fig. 3, and it is to be observed that the
curve of the foot forms a rolling fulcrum that
gives the greatest leverage in startingthe nail
and a more rapid movement after the nail is
started. 50
Having thus described my invention, I claim
as new and desire to secure by Letters Patent-
1. In a pipe-wrench, the bar or lever, in
combination with the pivoted arm having re-
versely-hooked ends, one of said hooked ends 55
having a greater curvature than the other said
hooked end, substantially as and for the pur-
pose set forth.
2. In a pipe-wrench, the bar or lever hav-
ing a lower curved and serrated end, in com- 6o
bination with the pivoted arm having re-
versely-hooked ends, one of said curved ends
having a greater curvature than the other said
hooked end, substantially as and for the pur-
pose set forth.
WILLIAM S. MORRISON.
