PROVISIONAL SPECIFICATION.
Improvements in Movable Wrenches for Cycles and other Machines.
I, FREDERIC GREENER, of Edmund Street Birmingham in County of
Warwickshire, Cycle Manufacturer do hereby declare the nature of this invention
to be as follows:-
My movable wrenches or spanners are made in the usual way with one movable
jaw. My improvements consists in modifying the handle or body of the wrench
in the following manner-I cast or pierce in the handle of my wrench one, two,
or more holes, below the nut which moves the movable jaw. These holes are
destined to fit the nuts on the machines with which the wrench is supplied.
With reference to the shape of these holes, I preferably adopt the hexagonal
form but the holes may be of any convenient shape for turning a pin or nut.
The end of the movable jaw which is screwed to nut, the nut by which the jaw
is opened is continued through this into the hole or holes I make in the body of my
wrench.
The object of this is to enable the user to apply the wrench to a nut smaller
than the hole and by tightening up the tail end of the jaw against one side of the
nut to prevent it slipping.
Dated this the 15th day of November 1893.
COMPLETE SPECIFICATION.
Improvements in Movable Wrenches for Cycles and other Machines.
I, FREDERIC GREENER of 6 Lower Temple Street Birmingham, Cycle
Manufacturer, late of Edmund Street Birmingham 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 :-
Movable wrenches or spanners for cycles and other light machines are usually
made in three pieces of metal; which I will call the " body" the "jaw" and the
"nut."
In the
The
It is in modifying the "body" or handle of the spanner that my improvement
consists, the "jaw "and nut being exactly similar to those in general use.
accompanying drawing Fig. 1; B is the body; J the jaw; and N the nut.
body of my wrench is grooved in the usual manner by a longitudinal slot, obling
in form, commencing at one end and terminating in an oblong hole H pierced
through the body of the wrench to receive the nut N.
The leg L of the jaw J fits into this slot and slides easily along it.
The leg L is obling in section, where it fits the slot in the body but is shaped
down to the round form and screwed to fit the nut N.
Below the hole H I pierce in the body of the wrench, one, two or more holes,
preferably hexagonal in form, but if required of any shape to meet the purposes of
the user.
In the drawing Fig. 1, 1 show two holes C and D.
The screwed part of the leg L is long enough to pass through into the holes C
and D, when the jaw is closed; the body being drilled for this purpose.

page_text: These holes C and D are for turning nuts or bolts, requiring a heavy strain, or
for nuts or pins too large to be conveniently turned by the other end of the
wrench.
In case a smaller nut is required to be turned by the holes C and D the screwed
part of the leg L can, be screwed down on to one side of it by turning the nut N
and closing the jaw of the wrench.
Fig. 2 shows a nut clamped between the screw end and one side of the hexagonal
hole.
The holes C and D make the spanner lighter and longer, also more shapely and
convenient to handle.
The holes C and D may be used as fixed spanners to nuts of a given size such
as the leading nuts of a bicycle and must not necessarily be made in conjunction
with the extension of the screwed jaw J.
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;
"Improvements in movable wrenches for cycles and other machines" by piercing
the body or handle part of the wrenches by a hexagonal or other shaped hole or
holes, which said hole or holes, may be used as fixed spanners; or in conjunction
with the screwed end of the jaw as improved movable spanners or wrenches.
Dated this 11th day of September 1894.
