page_text: I, DANIEL METCALFE, of 331, 10th Street, Troy, N.Y., U.S.A., Inventor, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to provide a wrench which is simple in construction
and not liable to get out of order.
My improved wrench comprises a bar of metal, bent up at one end to form a fixed
jaw, and having its other end screw-threaded for a part of its length. A movable jaw
is adapted to slide upon the bar and is held thereto by a clip. The screw-threaded
part of the bar enters a tubular handle which has a lug, at its inner extremity, which
engages a slot in the movable jaw. A nut is fitted to turn freely in the outer extremity
of the tubular handle, and is retained in position by a pin which projects from the
interior surface of the handle and enters an annular groove in the nut. The nut
engages the screw-threaded portion of the bar which can be thereby adjusted.

I, DANIEL METCALFE, of 231, 10th Street, Troy, N.Y., U.S.A. Inventor, 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 relates to improvements in wrenches; and it consists of the novel
construction and combination of parts hereinafter described and subsequently claimed.
Reference is to be had to the accompanying drawings, and letters of reference
marked thereon, which form a part of this specification.
Similar letters refer to similar parts in the several figures therein.
Figure 1 of the drawings is a view in side elevation of my improved wrench.
Fig. 2 is a central longitudinal section of the same. Fig. 3 is a cross section of the
same taken on the broken line 3-3 in Fig. 1.
A is the handle of my improved wrench, and B the outer jaw. The handle
comprises a barrel adapted to receive the outer jaw arm B'. The end of the arm B'
is inserted in the barrel and terminates in a screw-threaded shank B', adapted to
receive the adjusting nut B³, located partly within the barrel and provided with a
projecting enlarged milled head B, by means of which the nut may be rotated. The
inner portion of the nut is provided with an annular groove B, adapted to receive
the inner end of a screw S, inserted through the barrel wall, whereby longitudinal
movement of the nut is prevented while it may be freely rotated, the intermediate
portion of the arm B', between the threaded shank and jaw, is angular in form and
adapted to move longitudinally through slideways formed in the inner end wall of the
barrel end in the clip C, secured to the arm C, which supports the inner jaw C³.

page_text: The outer end of the inner jaw arm C¹ is provided with a vertical slot C³, adapted to
receive the flat shank D of the inner jaw C, the slot walls are provided with bottom
edge grooves C, adapted to receive the trunnions (of the inner jaw, whereby a
limited rotary movement of the inner jaw is permitted, while the trunnions are secured
between the shank or arm B' of the outer jaw and the supporting arm of the inner
jaw. The arm is provided with a slot C, adapted to receive a lug or flange A' on
the barrel, whereby the arm is held from longitudinal movement. The jaws may be
provided with teeth T when desired.
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 :-
In a wrench, the combination with a barrel handle A, inner and outer jaws and
jaw arms, one of said arms having a slot C adapted to receive a lug A' on the barrel
and a slideway-clip embracing the other arm, said other arm being inserted through
an end aperture in the barrel and provided with a screw threaded shank; of an
adjusting nut rotatively secured within the barrel upon the screw threaded shank, and
having a projecting operating head, substantially as described.
