"
The first combination of parts consists of a suitable frame of wood, iron, or
other material. In this frame a fixed jaw is inserted with packing pieces behind
it which are intended to adjust the size or "guage" of the coke to be broken.
movable jaw is also inserted having a fulcrum at the top, and connected by a rod
or toggle at the bottom with a crank to produce the reciprocal motion or "stroke
necessary for operating upon the coke to be broken. Any ordinary appliance can
be used to produce this motion. The jaws are intended to be furnished with
pointed spikes, chisel-spikes, or with cutting knives or ridges of steel or other hard
metal. The knives or edges may be either straight or curved with plain or
serrated edges. The spikes, chisel-points, or knives, may be used on both jaws or
on one jaw only, while the other may have a horizontally corrugated or roughened
surface.
The second combination of parts consists of a double series of bars of steel or
hard metal so arranged as to be open at the top and to close upon each other at
the bottom. On one side these bars may be fixed while on the other they may
be actuated by a crank, eccentric, or any ordinary means of producing reciprocal

on the opposite side.
The third combination of parts consists of a double series of discs formed of
hard metal arranged upon two shafts with screw adjustment to regulate the size
of coke to be broken. Between the discs distance pieces are to be inserted, so
that each disc will be opposite a space on the other shaft.
With any of these combinations a comb may used, the teeth of which are
intended to clear any pieces of coke sticking in any part of the machine. One of
these combs may be fixed in the case of a moving jaw or disc, or may have a
motion applied to it in the case of a fixed jaw.
It is also intended to use any ordinary means of producing a small jigging
motion with any kind of screening apparatus that may be used in connection*
with these machines, although such screening apparatus does not form any part of
our Invention.

City of London, and GEORGE MANT, of One hundred and five, Louise Road,

WHICH MAY BE APPLIED TO COAL AND OTHER MATERIAL."
"
Our Invention for improvements in coke breaking or splitting machines consists
of certain combinations of parts with alternative portions, as hereinafter described.
The first combination of parts consists of a suitable frame of wood, iron, or other
material. In this frame a fixed jaw is inserted; this jaw may be provided with
packing pieces behind it which are intended to adjust the size or guage of the coke
to be broken. A movable jaw is also inserted having a fulcrum at the top, and
connected by a rod or toggle with a crank to produce the reciprocal motion or
"stroke necessary for operating upon the coke to be broken; any ordinary
appliance can be used to produce this motion. The jaws are intended to be
furnished with pointed spikes, chisel spikes, or with cutting knives or ridges of
steel or other hard metal.
The knives or edges may be either straight or curved with plain or serrated
edges. The spikes, chisel points, or knives may be used on both jaws or on one
jaw only, while the other jaw may have a horizontally corrugated or roughened
surface. Two or more jaws may be used in one frame with reverse or differential
motions applied to them; double jaws may also be used, and the machine may be
either driven by a belt or may be combined with a steam engine, gas engine,
hydraulic, or other power.
The second combination of parts consists of a double series of bars of steel or
hard metal, so arranged as to be open at the top and to close upon each other at
the bottom; on one side these bars may be fixed, while on the other they may be
actuated by a crank, eccentric, or any ordinary means of producing reciprocal
motion; the coke is cut by the action of one set of bars forcing it through those
on the opposite side.
With either of these combinations a comb may be used, the teeth of which are
intended to clear any pieces of coke sticking in any part of the machine; the comb
may have a motion applied to it.
It is also intended to use any ordinary means of producing a small jigging
motion with any kind of screening apparatus that may be used in connection with
these machines, although such screening apparatus does not form any part of our
Invention.
In order that our said Invention may be fully understood, we shall now proceed
more particularly to describe the same, and for that purpose shall refer to the
several Figures on the Drawing hereunto annexed. Fig. 1 is a vertical section,
and Fig. 2 is a plan of splitting machine. a is the moving jaw actuated by the
crank b; c is the toggle or connecting rod; this jaw is furnished with spikes or
chisel points, which are shewn secured with nuts, but may be otherwise secured;
knives may be fixed upon the jaw instead of spikes. d is the fixed jaw, shewn
with the front roughened, but which may be furnished with spikes, chisel points,
or knives; behind this jaw, packing pieces shaped like magnets are seen in the
section, and also at e on plan; these are intended to adjust the size of the material
to be broken. The comb f is shewn in front of the jaw, the lower ends of which
are arranged to strike against the fixed bar g during the return stroke of the jaw,
and so clear any pieces of coke or other material worked upon from sticking

page_text: in between the spikes; other motions may be given to the comb to suit various
materials treated; h is a bolt securing the fixed jaw.
Fig. 3 is a vertical section shewing a similar arrangement with a double jaw i
furnished with spikes, chisel points, or knives both top and bottom; this jaw is
shewn actuated by an hydraulic ram j, j, at each end, one crank k working the
double plunger for both rams; the fixed jaws and comb are as before described.
Fig. 4 is a section shewing a double series of bars of steel or hard metal m, m,
arranged to be open at the top, and closing upon each other at the bottom; on one
side the bars are fixed, while on the other the series are actuated by a crank n and
connecting rod o; the combs p, p, the teeth of which come between all the bars,
have a small vertical motion imparted to them by the cranks q, q, and lever r
actuated by an eccentric upon the crank shaft, not shewn on the Drawing. The
number of bars m, m, arranged in a series within the frame may vary according to
the size of the machine it is desirable to make.
Having thus described the nature of our said Invention, and the manner in
which the same is or may be used or carried into effect, we would have it under-
stood that we claim,-
First. The use of spikes, chisel points, or knives, in combination with movable
and fixed jaws, as shewn, substantially as herein before described.
Second. The application of a comb in combination with spikes, chisel points, or
knives for releasing the material from the said spikes, chisel points, or knives,
substantially as herein before described and shewn.
Third. The application of a series of bars forming jaws, with moving combs
between them, substantially as described and shewn.
In witness whereof, we, the said William Francis Anderson and George
Mant, have bereunto set our hand and seal, this Twenty second day of
June, in the year of our Lord One thousand eight hundred and eighty one.
