page_text: I, JOHAN WICKTOR BJÖRKLIND, Manufacturer, of Grillby, Sweden, do hereby
declare the nature of this invention to be as follows:-
This invention pertains to improvements in wrenches for the gripping and
turning of pipes, nuts or the like, and the object of the invention is to obtain a
more handy and convenient wrench than those hitherto known.
In the accompanying drawing Figure 1 is a side-elevation of a wrench according
to this invention, Fig. 2 an edge-elevation of the same with parts of the legs broken
off and Fig. 3 another such edge-elevation.
The wrench consists as usual of two legs a and b provided on one end with
suitable jaws for gripping the pipe. The one leg a consists of two parts c and d of
which the part d forms the handle and is on one end provided with screw-threads
and screwed through the one end of the other part c, which in one end is provided
with corresponding nut-threads. The leg b is bent and either inserted through a
suitable opening in the part of the leg a, as shown in the drawing, and held there
by a pin e or the like, or the leg b may be provided with an opening through which
the part e is inserted in the same manner. The screwthreaded end of the part d
is joined to the back of the jaw of the leg b by a balljoint f, g, or the like, in
such a manner that the handle ends of the legs a and b may be separated or brought
together, as well as the part / turned around. When the jaws are to be adjusted
for a given size of pipe the handle ends of the legs a and b are separated. If the
distance between the jaws is too small the part d of the leg a is screwed back,
pulling with it the leg b, so that the jaws separate. If the distance between the
jaws is too great, the part d is screwed in, pushing the leg b, so that the distance
between the jaws diminishes. As usual the jaws will be made to firmly grip the
pipe by pulling the handle ends of the legs together.
It is obvious that in this wrench the part d may be turned, for adjusting the
distance between the jaws, without removing the hands from the handle-ends of
either of the legs. This is a special advantage of this wrench.
Instead of inserting one of the legs through an opening in the other, one of the
legs may of course be provided with suitable guides in which the other leg is
held and guided.

page_text: I, JOHAN WICKTOR BJORKLIND, Manufacturer, of Grillby, Sweden, 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:-
This invention pertains to improvements in wrenches for the gripping and
turning of pipes, screw-nuts or the like, and the object of the invention is to obtain
a more handy and convenient wrench than those hitherto known.
In the drawing left with the provisional application, l'igure 1 is a side-elevation
of a wrench according to this invention; Fig. 2 is an edge-elevation of the same
with parts of the legs broken off, and Fig. 3 another such edge-elevation.
Referring to the drawing, a and b represent two legs or bars each provided at one
end with suitable jaws for gripping the pipe, nut or the like. The one leg a
consists of two parts c and d of which the part d forms the handle and is on one
end provided with screw-threads and screwed through the back end of the
jaw-part c, which is provided with corresponding nut-threads. The leg b is bent
and either inserted through a suitable opening in the part c of the leg a, as shown in
the drawing, and held there by a pin e and two loose semi-elliptical guides, or the
like, or the leg b, may be provided with an opening through which the jaw-part c
is inserted in the same manner. The screwthreaded end of the part d is joined to the
back of the jaw of the leg 6 by a ball and socket joint f, 9, in such a manner that the
handle-part d may be turned for screwing in and out without preventing the handle
ends of the legs a and b being separated or brought together. When the distance
between the jaws is to be adjusted for a given size of pipe the handle ends of the
legs a and b are separated. If the distance between the jaws is too small the part d
of the leg a is screwed back, pulling with it the leg b, so that the jaws separate. If
the distance between the jaws is too great, the part d is screwed in, pushing the
leg b forward so that the distance between the jaws diminishes. As usual the jaws
will be made to firmly grip the pipe by pulling the handle ends of the legs
together, there being sufficient play in the ball and socket joint to allow for this.
It is obvious that in this wrench the part d may be turned for adjusting the
distance between the jaws, without removing the hands from the handle ends of
either of the legs, which is a special advantage of this wrench.
Instead of inserting one of the legs through an opening in the other, one of the
legs may of course be provided with suitable guides in which the other leg is held
and guided.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a pipe-wrench or the like the one leg of which consists of a jaw part
and a handle part screwed through the back end of the said jaw-part, a ball
and socket joint uniting the fore end of said handle part to the back of the jaw
of the other leg, substantially as and for the purpose set forth.
2. In a pipe-wrench or the like, the combination of a leg consisting of a handle
part and a jaw part through the back end of which said handle part is screwed,
another leg crossing the said jaw part, and a ball and socket joint uniting the end

page_text: of the said handle part of the one leg to the back of the other leg, substantially as
and for the purpose set forth.
