GEORGE WILLIAM MCINTYRE 113 Brooke Road Stoke Newington London N.
Telegraph Clerk and ROBERT FRANK BRADFORD 93 Osbaldeston Road Stoke
Newington London N. Postal Clerk do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to save labor, and to considerably lessen the
time occupied in fixing and unfixing nuts bolts etc. of any size by the adjustment
of interchangeable plates with square or polygonal eyes. To accomplish this I
make a wheel, the periphery of which is edged by a double set of ratchet teeth,
there being a space left between each set which forms a groove, in which I place a
band coming flush with the above mentioned teeth. In the interior of the wheel is
cut a groove almost equal in width to the thickness of the wheel. Within this
groove are placed two stops directly opposite one another. I next cut two slots in
the flat surface of the wheel, which are also directly opposite one another, for the
purpose of receiving the projections of the plates, which, after entering the slots,
traverse the groove as far as the two stops or bearing points before mentioned.
When the projections reach these points, a small slide is shot across the plate to
keep it stationary on the backward motion of the lever. The handle or lever, to
which a pawl is attached, in order to give the whole an intermittent motion, is
bolted on to the band above referred to.

I, GEORGE WILLIAM MCINTYRE 113 Brooke Road Stoke Newington
London N. Telegraph Clerk, and ROBERT FRANK BRADFORD 93 Osbaldeston
Road Stoke Newington London N. Postal Clerk, 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:
-
The object of this invention is to save labour and to considerably lessen the
time occupied in fixing and unfixing nuts, bolts &c.; of any size by the adjustment
of interchangable plates with square or polygonal eyes. To accomplish this [
make a wheel the periphery of which is edged by a double set of ratchet teeth,
there being a space left between each set which forms a groove in which I place a
band coming flush with the above mentioned teeth. In the interior of the wheel is
cut a groove almost equal in width to the thickness of the wheel. Within this
groove are placed two stops directly opposite one another. I next cut two slots in
the flat surface of the wheel, which are almost directly opposite one another, for the
purpose of receiving the projections of the plates which after entering the slots
traverse the groove, as far as the two stops or bearing points before mentioned.
When the projections reach these points a small slide is shot across the plate to

page_text: keep it stationary on the backward motion of the lever. The handle or lever to
which a pawl is attached in order to give the whole an intermittent motion is
bolted onto the band above referred to.
In order that my invention may be fully understood I now refer to the annexed
drawings in which :-
Figure 1, front elevation of my invention.
Figure 2, side elevation of same.
a is a circular plate having projections & c; this plate a is carried in the outer
wheel or rim d which has a groove shown by the dotted lines e in which the
projections & c engage c¹ being apertures for the passage of the projections & c.
f is a sliding catch piece which locks the plate a in position. is a band which
engages in a groove in the outer wheel or rim d which has the ratchet teeth g upon
same in which the pawl i engages, said pawl being controlled by the spring j.
m & nare small stop pieces in the groove against which the projections b & e engage.
It will be seen that the " eye' or opening o in the plate a can be of a desired
shape and by using plates having the required shape of "eye" various nuts may
be operated. The band is secured to the handle or lever k. The nut enters
the "eye" or aperture and by operating the lever or handle k the nut may be
tightened or loosened as desired, the pawli, operating the ratchet wheel d in one
direction of motion and running free on the wheel d, in the other direction of
motion.
"
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. An improved spanner consisting of an outer rim or wheel having ratchet
teeth and in which a plate having projections engages said projections engaging in
an inner groove having stop pieces, said plate having an "eye or aperture of
suitable configuration or shape to engage on the nut to be operated, a pawl
engaging in the teeth on said outer wheel or rim and controlled by a spring, said
pawl being pivoted to a handle or lever to which the ends of a band are attached
said band engaging in a groove encircling the outer wheel or rim substantially as
described and illustrated.
