PROVISIONAL SPECIFICATION.
Improvements in and Apparatus for Preparing Coke for Use in
Slow Combustion Stoves.
I JOHN JAMES ROYLE of 27 and 29 King Street West, Manchester, in the County
of Lancaster, Mechanical Engineer, do hereby declare the nature of my invention to
be as follows:-
This invention relates to a novel method of and simple arrangement of mechanism
for treating coke whereby the same is readily crushed by hand labour and rendered
suitable in size for use in slow combustion stoves and specially for domestic purposes.
In performing my invention 1 employ a hopper to hang as a bracket upon the wall
or which may be provided with legs and thus be self-supporting. The outside plate
of this hopper is mounted upon pivots at the top so as to be suspended in position and
in order to cause this plate to make a fraction of a revolution upon its pivots or axes
and thus to cause the lower part thereof to slightly approach the opposite side of the
hopper and to crush the coke lying in the hopper and between the two surfaces,
I employ a lever handle, the shorter arm of which is in the form of one or more cams
or their equivalents. These cams gradually press upon the outside of the suspended
plate as the handle of the lever is pushed downwards and thus exercise the necessary
pressure and crushing action upon the coke whilst, when raised up, the same lever, by
causing the cams to retire, so withdraws the pressure from the suspended plate and
permits the crushed coke to fall through the now-open slit at the bottom say into a
coal box or other receptacle placed at the spout of the hopper to receive it.
In another modification of my invention operate the cams by a shaft and spur or
other gearing operated by a winch handle or its equivalent.
Dated this 24th day of January 1886.

Improvements in and Apparatus for Preparing Coke for Use in
Slow Combustion Stoves.
I JOHN JAMES ROYLE of 27 and 29 King Street West, Manchester, in the County
of Lancaster, Mechanical Engineer, do hereby declare the nature of my 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 a novel method of and simple arrangement of mechanism
for treating coke whereby the same is readily broken by hand labour and rendered
suitable in size for use in slow combustion stoves and specially for domestic purposes.
On the accompanying drawing I illustrate in Fig. 1. a front view of my improved
apparatus and in Fig. 2. a side sectional view of the same taken on the line a-b. in
Fig. 1.
In performing my invention I construct a cast iron hopper A. to hang as a bracket
upon the wall say by means of the lugs B. and bolts and nuts B', or, which hopper
may be provided with legs and thus be self supporting. The outside plate C. of this
hopper is mounted upon pivots D. D. at the top so as to be suspended in position and
in order to cause this plate C. to make a fraction of a revolution upon its pivots or
axes D. D. and thus to cause the lower part thereof to slightly approach the opposite
side of the hopper and to break the coke lying in the hopper and between the two
surfaces (which I prefer to serrate as illustrated) I employ a lever handle E. mounted
upon the bolt E' the shorter arms e e¹ of which lever are in the form of one or more
cams or friction rollers F. F. or their equivalents. These cams or rollers F. F.
gradually press upon the outside of the suspended plate C. as the handle of the
lever E. is pushed downwards say to the definite position indicated in Fig. 2. and thus
exercise the necessary pressure and breaking action upon the coke, whilst, when
raised up, say to the position indicated by the dotted line in Fig. 2. the same lever E.
by causing the cams or rollers F. F. to retire, so withdraws the pressure from the
suspended plate C. and permits the broken coke to fall through the now open slit at
the bottom say into a coal box or other receptacle placed at the spout of the hopper to
receive it.
By means of the adjusting screw G. the extreme traverse or distance of the bottom
of the outside plate C. from the back of the hopper (and consequently the width of
the open slit at the bottom of the hopper) is adjustable to the greatest nicety and
thus facility afforded for regulating the size to which the coke is required to be
broken.
It will thus be observed that my improved apparatus constitutes an useful hand
machine for breaking coke and for rendering the same more reliable and especially for
feeding slow combustion stoves.

page_text: In another modification of my invention I operate the cams or rollers by a shaft
and spur or other gearing operated by a winch handle or its equivalent.
Having thus particularly described and ascertained the nature of my invention and
in what manner the same is to be performed I declare that what I claim is :-
1st. The improvements in and apparatus for preparing coke for use in slow
combustion stoves substantially as herein before described and. illustrated on the
accompanying drawing.
2nd. The combination and arrangement of parts constituting an apparatus or hand
machine for breaking coke when mounted and operated substantially as hereinbefore
described and illustrated on the accompanying drawing.
