Complete Specification Left, 21st Mar., 1896-Accepted, 2nd May, 1896
We WILLIAM SNELGROVE of 217 Bradford Street Birmingham Engineer and
RICHARD FRANCIS GOYNE of 16 Bromsgrove Street Birmingham Merchant do
hereby declare the nature of this invention to be as follows:-
We cut two plates of sheet metal to suitable size and shape to form the front
and back of our padlock, these plates having each a gap on their upper sides for
the passage of the bolt or catch and being joined together either at their edges
or by a central pin with sufficient space between them to permit of the movement
of the bolt or catch hereinafter described.
The bolt or catch two or more of which we preferably use in each padlock
consists of a circular band of metal having a gap at one point of nearly similar
space to the aperture in the front and back plates previously described and this
band is retained loosely in position either by the turned over edges of the said
frame plates or by a central boss in such a manner that it can be readily turned in
a circular direction to bring its aperture either parallel or otherwise to the gap in
the frame plates thus respectively unlocking or locking the padlock as desired.
The use of two or more bands makes it more difficult to bring these apertures
simultaneously together and thus increases the difficulty in opening the lock.
In a slight modification of our invention we construct our bolt as in the shape of a
wheel in which the periphery with a gap cut out of it forms the actual locking
bolt being kept in a central position to its hub by a single radial arm or spoke.
This wheel shaped bolt or catch of which we preferably use two or more to each
padlock, revolves on its centre on a pin passing through its hub and the two frame
plates before described.
In both forms of our invention before described the only portion of the bolt or
bolts visible to the user and by which the bolts can be moved is that portion that
happens to be opposite the gap in the frame plates.
Dated this the 21st day of June 1895.

We, WILLIAM SNELGROVE of 217 Bradford Street, Birmingham, Engineer, and
RICHARD FRANCIS GOYNE, of 16 Bromsgrove Street, Birmingham, Merchant, 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:-
We cut two plates of sheet metal to suitable size and shape to form the front
and back of our padlock, these plates having each a gap on their upper sides for
the passage of the bolt or catch, and being joined together either at their edges or
by a central pin with sufficient space between them to permit of the movement of
the bolt or catch hereinafter described.

page_text: The bolt or catch, two or more of which we preferably use in each padlock,
consists of a circular band of metal having a gap at one point of nearly similar
space to the aperture in the front and back plates previously described, and this
band is retained loosely in position by the turned over edges of the said frame
plates in such a manner that it can be readily turned in a circular direction to
bring its aperture either parallel or otherwise to the gap in the frame plates, thus
respectively unlocking or locking the padlock as desired.
The use of two or more bands makes it more difficult to bring these apertures
simultaneously together and thus increases the difficulty in opening the lock.
In a slight modification of our invention we construct our bolt as in shape of a
wheel in which the periphery with a gap cut out of it forms the actual locking bolt
being kept in a central position to its hub by a single radial arm or spoke. This
wheel shaped bolt or catch of which we preferably use two or more to each padlock,
revolves on its centre on a pin passing through its hub and the two frame plates
before described.
In both forms of our invention before described, the only portion of the olt or
bolts visible to the user and by which the bolts can be moved is that portion that
happens to be opposite the gap in the frame plates.
Our invention will be understood by reference to the accompanying sheet of
drawings.
Figs. A & B, show the two plates of sheet metal forming the back and front of
the lock.
Fig. C, shows one form of bolt or catch before described.
Fig. D, shows the wheel shaped bolt, previously described as a modification of
the bolt C.
Fig. M, shows the bolt D, in position, the dotted lines showing one of the frame
plates A or B.
One or more of either of the bolts C or D, being enclosed between the two
frame plates A B, with freedom to revolve in a circular direction, bolts of the form
of C, being retained in position by the turned over edge of A & B; while bolts
of the form of D, are retained in position by a pin passing through their hubs at
the point E, the said pin being fastened on either side to the centre of the frame
plates A & B, which form the front and back of the padlock.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :
In a toy puzzle padlock, the combination of the frame plates A & B, with the
bolts or catches C or D, substantially as herein before described and as illustrated
in the accompanying sheet of drawings.
Dated this 20th day of March 1896.
