PROVISIONAL SPECIFICATION.
A Novel Manufacture of Combined Edge Toothed and Face Toothed
Wheels specially applicable for Coin Receivers of Coin Freed
Machines.
We, RICHARD THOMAS GLOVER and JoHN GEORGE GLOVER, of the Firm Thomas
Glover and Co. Ltd., 21 to 222, St. John Street, Clerkenwell, London, Gas Meter
Manufacturers, do hereby declare the nature of this invention to be as follows:-
This invention has for object, the manufacture of combined edge toothed and
face toothed wheels by a succession of stamp cutting for edge teeth, stamp
cutting blanks for face teeth formation and finally by stamp pressure for bulging
such blanks to constitute the face teeth.
For the purpose of our invention, we take, say, a disc of brass or other ductile
metal and form a hole in its centre, the edge of which hole we draw out to form
a projecung ring from one face of said disc. This ring is then strengthened
by a ferrule so that it may serve as a boss for future mounting on a spindle.
The dise is then stamp cut to form the edge teeth which may be of the ordinary
or of the ratchet kind as desired. The disc is next stamp cut through in radiat
nes from, say, the back face preferably under guidance of a dividing machine
or template according to the number of teeth to be formed after which by a
bulging tool and a matrix bed each alternate portion of the cut through part is
forced in and shaped to that of a tooth of the required design for the purpose
intended.
The invention is chiefly based upon the coin receiver disc wheels of a previous
l'atent granted to us on the 29th day of December 1894, No. 25272, the object
being to render them more efficient in their action and less liable to damage from
rough treatment, the face teeth having no sharp edges that otherwise are easily
burred, it also prevents sharp cuts being given to the coin while engaged in the
teeth

Machines.
We, RICHARD THOMAS GLOVER and Joux GEORGE GLOVER, of the Firm Thomas
Glover and Co. Ld., 214 to 222, St. John Street, Clerkenwell, London, Gas Meter
Manufacturers, do hereby declare the nature of this invention and in what
Price Sd1

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention has for object. the manufacture of combined edge toothed and
face toothed wheels by a succession of stamp cutting for edge teeth and stamp
cutting blanks for face teeth formation and finally by stamp pressure for bulging
euch blanks to constitute the face teeth and shaping same if required.
Our invention will be clearly understood from the following description aided
by the accompanying drawings.
Figures and are elevation and edge view respectively of a dise having the
edge teeth stumped and the ring boss projecting from the centre and constituting
the first stamping process.
Figures 3 and elevation and edge view respectively of the dise having the
edge teeth and the face teeth stamped out in a plain condition.
Figure 5 is an elevation of the disc having the edge teeth and face teeth stamped
out and pressed into a finished condition as suitable for forming the coin wheel
in a coin freed gas meter, a ferrule surrounding the ring for strengthening pur
Joses.
Figure 6 is a section of the dise. Figure 5. looking in one direction and Figure 7
is a section of the disc. Figure 5. looking in the other direction.
For the purpose of our invention, we take, say, a dise A of brass or other ductile
metal and form a hole B in its centre, the edge of which hole B we draw out
to form a projecting ring C from one face of said dise A. This ring C is then or
afterwards strengthened by a ferrule D, so that it may serve as a boss for future
mounting on a spindle. The disc A is then stamp cut to form the edge teeth E.
as at Figure 1. which teeth may be of the ordinary or of the ratchet kind as
desired.
The disc is next stamp cut through in radial lines from, say, the back face.
preferably under guidance of a dividing machine or template according to the
number of teeth to be formed, after which by a bulging tool and a matrix bed
each alternate portion of the cut through part is forced in and shaped to that of a
tooth of the required design for the purpose intended, as at Figure 3 or 5. or the
shaping. Figure 5. may be effected by another pressing operation.
The invention is chiefly based upon the coin receiver dise wheels of a previous
Patent granted to us on the 29th day of December 1894. No. 25272, the object
being to render them more efficient in their action and less liable to damage from
rough treatment, the face teeth having no sharp edges that otherwise are easily
burred, it also prevents sharp cuts being given to the coin while engaged in the
teeth.
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:-
1. The manufacture of combined edge toothed and face toothed wheels specially
applicable for coin receivers of coin freed machines by stamp pressing in successive
operations substantially in the manner described.
2. The manufacture of combined edge toothed and face toothed wheels from
blanks by stamp cutting and pressure for producing successively, a walled hole in
the centre, teeth on the edge, radial cuts or slits, bulging each alternate portion
of the cut through part as face teeth and shaping the bulged portions, substantially
as set forth.
