Improvements in Wrenches.
I, ROBERT JOHN STROUD, of Milford Bay, in the County of East Simcoe,
Province of Ontario, Canada, Builder, do hereby declare the nature of this inven-
tion, 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 particular relation
to devices of this character, suitable for use in different positions.
The object of my invention is to provide an adjustable wrench which can be
used either at the end or the sides; which can be readily placed in position for
use; which is neat and attractive in appearance, durable in construction, simple
and efficient in operation, and which can be made at a low cost.
To these and other ends, my invention consists in the improved construction
and combination of parts, hereinafter fully described, and particularly pointed
out in the appended claims.
In the accompanying drawings, forming a part of this specification, and in
which similar numerals of reference indicate similar parts in all of the figures,
Figure 1 is a perspective view of a wrench formed in accordance with my inven-
tion, parts being broken to enable a showing on a larger scale.
Figure 2 is a similar view taken from the opposite side.
Figure 3 is a perspective view of the operative handle.
Figure 4 is a cross-sectional view of the handle, taken through one of the
openings.
It is oftentimes necessary that plugs, nuts, etc., be placed in a position where
it is impossible for the ordinary wrench to be used. This is especially true of
plugs in gas mains, nuts located within tubes, etc. These have been generally
operated by means of taps, etc., which, not being adjustable, are not of general use.
The present invention is to provide a wrench for this purpose, which can be
adjusted for use with plugs and nuts of various sizes.
In the drawings 1 designates the fixed member of the wrench, having its inner
end curved as at 2, to meet the curved end 3, of the movable member 4. The
members 1 and 4 are hingedly connected together by means of the pin 5, and
are normally held separated by means of the coiled spring 6 inserted between
the members, on lugs 7 secured to the inner face of each member. To adjust the
position of the movable member relative to the fixed member, I provide a suit-
able bolt 8 having a thumbnut 9, the bolt 8 being passed through a suitable
opening formed in the fixed member, and a slot 10 formed in the movable mem-
ber, the latter being provided to allow of the movement of said member on its
pivot. The member 4 is of greater length than the member 1.
The fixed member is provided with a rearwardly extending shaft 11, preferably
formed square, said shank having its rear end reduced as at 12, to allow of the
placing thereon of a handle 13. The handle provided with openings 14, con-
forming to the shape of the reduced end 12, these openings being arranged at the
centre and at one end, to allow of the obtaining of a greater leverage when desired.
As it is sometimes preferable to operate the wrench by means of a second

page_text: wrench adapted to be placed on the shank, I provide a pin 15 at the rear end of
the shank, said pin being adapted to enter an opening 16 formed near one end of
the handle, thus forming a bearing by means of which it is possible to keep the
wrench in a true position. If desired, a suitable spring actuated pin 17 may be
located on said handle, adapted to enter an opening 18 formed at the end of 12.
The operation of the wrench is apparent, and the advantages derived from its
use have been heretofore set forth.
While I have herein shown a preferred form of carrying my invention into
effect, yet I do not desire to limit myself to such preferred details of construction,
but claim the right to use any and all modifications thereof which will serve to
carry into effect the objects to be attained by this invention, in so far as such
modifications and changes may fall within the spirit and scope of my said
invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
"1.
1. The combination with a wrench provided with a rigid handle terminating
in a beveled end, of an auxiliary handle provided with beveled sockets for the
reception of said beveled handle-end, substantially as described.
2. The combination with a wrench provided with a rigid handle terminating in
a beveled end, and having a perforation extending transversely through said
heveled end, of an auxiliary handle provided with a series of beveled sockets for
the reception of said beveled handle-end, and a spring secured to said auxiliary
handle and adapted to pass through a perforation in said beveled handle-end,
substantially as described.
3. The combination with a wrench provided with a rigid handle terminating
in a beveled end, and a pin projecting vertically from said beveled end, of an
auxiliary handle provided with beveled sockets for the reception of said beveled-
end, and perforations for the reception of said pin, substantially as described.
4. The combination with a wrench provided with a rigid handle terminating
in a beveled end, and having a perforation extending transversely through said
beveled end, a pin projecting vertically from said beveled end, of an auxiliary
handle provided with a series of beveled sockets for the reception of said beveled
handle-end, and a spring lug secured to said auxiliary handle and adapted to
pass through a perforation in one of said beveled sockets and engage the perfora-
tion in said beveled handle-end, said auxiliary handle being also provided with
perforations for the reception of said pin, substantially as described.
