My invention relates to an improved method of making adjustable spanners
or wrenches for tightening or slackening nuts, screws, bolts, and the like.
For this purpose I make the spanner or wrench in two parts, and each part-
which may be formed in one or more pieces has a suitably formed
jaw or projecting lip or arm at one end, one side of
both jaws overhangs and forms a slide or bearing, against which slides the lip
or projection formed on the other part when they are Iplaced together with the
jaws facing one another, so as to form a complete wrenchin

Each of these two parts is formed with a stem, or shank forming, the handle of
the spanner or wrench; and the base of. one of these shanks is formed with a
ledge or slide upon which slides the base of the other part.

By this means the one part of the wrench slides, upon bearings or ledges at
one or both ends in such a manner that "the space between the jaws can be
enlarged and reduced so as to take nuts, or 'bolt 'heads, and the like of various
sizes, and the act of turning the nuts or bolt heads automatically or otherwise
locks the two parts against one another at the bearings at one or both ends, and
thus prevents the jaws from expanding asunder by. reason of the cross action
which thus ensues against the jaws on the nuts or bolt heads. For securing the
two parts together, I may drill and tap a hole in the base of one part to receive
a screw which passes through a suitable slot in the base of the other part, or by
other suitable means.

In other cases I form the faces of the bearings or projections on each part with
suitable teeth, so formed that the teeth of one part may fit in the teeth of the
other part to form any desired space between the jaws of the spanner. And in
other cases I may make one part of the spanner with suitable slots top and bottom,
in which the other part may slide by suitable means; or I may make them, of
any other suitable form, but in all cases so as to effect.the same action and purpose
as described above. In some cases. I may form teeth on one or both of the jaws,
and I may use any desired combination of the parts described above to form my
improved wrench or spanner.

"In order that my invention may be fully understood, and more readily carried
out and into effect, I have appended hereunto one sheet of drawings, whereon:-
Figure 1 represents an elevation of one side of one form of spanner according
to my invention as described in the first part above.
Figure 2 represents an edge, or side view of the same spanner.
Figure 3 represents an elevation of the other side of this same spanner..
Figure 4 shows an elevation of another form of spanner according to my
invention as described in the second part above.
n
!
Figure 5 represents an edge or side view of this second form of spanner.
Similar letters of reference refer to similar parts throughout the various figures.
In Figures 1 to 3, the spanner is made of the two parts A and B, with the
jaws C, D, and the part B is formed with the bevelled lip or arm. E, which slides
on the projection or slide F formed on the part A
The base of the shank A¹ of part A is formed with a ledge or slide G, upon

page_text: which slides the bottom of the shank B2 of the other part B; and the two parts
are secured together by the wing nut W with the spring washer S under same,
and bolt K sliding in the slot P of the part A. The whole is so arranged that the
jaws C and D can be adjusted to any desired distance apart, so as to take nuts,
bolt heads, and the like of various sizes; and the act of turning the nuts and the
like locks the parts A and B against one another at the E, F, and G, and so
prevents the jaws from expanding from one another by reason of the cross action
which ensues with one part against the other.
In Figures 4 and 5, the spanner in this case is also made of the two parts A
and B, with the jaws C and D, but the part B is formed with the arm E¹ of a
rectangular or other suitable form so as to slide in a slot F formed in the part A;
and the lower end of the shank B2 is either formed with the screwed shank K in
one piece with it, or secured into it in a suitable manner. This shank K slides
in the slot l' formed in the base of the part A'; and the two parts A
and B are secured together--with the jaws C and D at any desired distance apart
-by the wing nut W, and spring or other washer S, being then screwed up home
on the shank K against the slotte end of part A; the same locking action ensuing
as is described above.
I may use any other suitable means of adjusting the parts A and B, other than
by the arrangements shown in the drawings; and in some cases I may dispense
with the bottom slides G or G¹, and rely upon the upper ones to lock the jaws C
and D, in combination with a bolt and nut or other suitable means. The jaws
may be serrated or made in any other suitable form, other than shown in the
drawings.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
:
1st. A spanner for turning nuts, bolt heads, and the like, formed in two or
more parts; one formed with one or more arms sliding on a suitable, bearing or
bearings formed on the other part; the two parts being held together by a bolt and
nut, or other suitable means for the purposes specified, and as shown in the
drawings.
2nd. In a spanner for turning nuts and the like such as is referred to in the
first Claim, forming it in two parts, each with one or more bearings capable of
sliding one upon the other so as to adjust the space between the jaws in combina-
tion with a suitable device for holding the two parts together for the purposes
named, and substantially as herein set forth and illustrated in the drawings
herewith.
3rd. The special arrangement, construction, and combination of parts to form a
spanner, all as shown in Figures 1 to 5 inclusive herewith for the purposes named
above, and substantially as described and shown on the drawings herewith.
