Improvements in Stone Breaking, Ore Crushing, and Pulverizing
Machines.
We CHARLES MASON Engineer 65 Sparkenhoe Street Leicester & AUSTIN HILL
Engineer 19 Watling Street Leicester do hereby declare the nature of this invention
to be as follows :-
Our invention has for its object improvements in Stone Breaking-Ore Crushing
and Pulverizing machines with moveable Jaws-And to make those machines available
for crushing and pulverizing as well as breaking stone in the ordinary way. To
obtain the required movement-we hang the swing Jaw upon the eccentric shaft-at
the top of the machine-and at the lower end of the swing Jaw-we fix in suitable
and adjustable bearings-a moveable lever-which acts upon the Jaw in such a manner
as to give it a powerful-combined-Breaking-grinding and pulverizing motion―
that will crush or pulverize to powder any hard material.
We also fix removeable-hard metal serrated surfaces to the Jaws of the machine-
with fine or coarse teeth-to break-grind-or pulverize, as may be required.

ordinary way. To obtain the required movement-we suspend in suitable bearings,
at the top of the frame of machine-the main shaft upon which we fix an eccentric, A-
(see drawing in figure 1) and upon the said eccentric we hang the swing Jaw, B
(see drawing in figure 1).
The eccentric shaft been driven by a pulley gives the swing Jaw-an upward and
downward movement as well as a powerful crushing motion. By this means we
get a double action, One for crushing and pulverizing. And the other for breaking
or cubing stone in the usual way.
In further carrying out our improvement we suspend in suitable bearings, at the
lower part of the frame of the machine-a second eccentric shaft C-(see drawing in
figure 2) upon which, we, mount a boss D-(see drawing in figure 2) of cast iron, or
other suitable material-with a receptacle to receive a lever or toggle plate E-(see
drawing in figure 2) to press against the back of the lower part of swing Jaw Bin
which we fix a steel groove for the lever or toggle plate to work in-and by means of
the said eccentric C-we move the lever or toggle plate backward or forward-to set
the swing Jaw in position-to break or crush the material any size required-The
said eccentric also enables us to fix the lever or toggle plate in such positions (see F & G
(in drawing figure 1) that we can give the swing Jaw any required movement-to
crush either hard or soft material.
Having now particularly described and ascertained the nature of our said invention-
and in what manner the same is to be performed, we do not claim any of the parts
separately which are well known-and in common use-in machines of the type,
forming the subject of the invention-but what we do claim is.
First The combined crushing and breaking motion-by the novel method of
hanging the swing Jaw upon the eccentric shaft, mounted on the top of the frame of
the machine in connection-with a lever or toggle plate, bearing against the lower
end of the swing Jaw.
Secondly The novel arrangement of using a second eccentric shaft, with a recessed
boss to receive a lever, or toggle plate, to act in a steel groove at the lower end of the
swing Jaw which enables us to set the swing Jaw in any position, to break material
either fine or coarse-as required-and also to raise or lower the lever or toggle plate-
to give any movement-to break or crush either, hard, or soft material.
