Improvements in Stone Breaking and Ore Crushing Machines.
We CHARLES MASON, Ironfounder 65 Sparkehoe St Loicester and AUSTIN HILL,
Engineer 19 Watling St Leicester do hereby declare the nature of our invention
for THE IMPROVEMENTS IN STONE BREAKERS AND ORE CRUSHING MACHINES to
be as follows: —
Our improvement consists in running-or attaching by suitable bearings-the
eccentric shaft in, or to, the swing jaw of the machine-by which a direct action
is obtained without the aid of pitman-toggle plates-cranks &c thus reducing the
friction to a minimum. By this means we get the full force of the power of the
eccentric upon the material to be operated upon-another advantage we gain by
the eccentric running in or been attached to the swing jaw is, the swing jaw is
withdrawn at every revolution-thus dispensing with drawback bolts, bars, india
rubber washers &c The bearings may be made of cast iron, steel, or any suitable
material by the above arrangements we claim to make the machine simpler,
more effective & economical than heretofore,

We CHARLES MASON of 65 Sparkenhoe St Leicester Ironfounder &c. & AUSTIN
HILL of 19 Watling St Leicester Enginer do hereby declare the nature of our
invention for JMPROVEMENTS IN STONE BREAKING AND ORE CRUSHING MACHINES
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
=
Our Improvement consists in running the eccentric shaft A. (see drawing in
fig. 1) in the ordinary swing jaw B (see drawing in fig. 1) of the machine, by
which arrangement, a powerful and direct action is gained and the full force of
the power of the eccentric is obtained upon the material to be operated upon―
without the aid of pitman-toggle plates-cranks or any intermediate connection
whatever.
We divide the bearing in the swing jaw B-(see drawing in fig. 2) into sections,
by this arrangement, only a portion of the eccentric A (see drawing in fig. 2) acts
upon the swing jaw-at one time in the form of two cams, C and D, (see drawing
in fig. 2) the other divisions E F are recessed (see drawing in fig. 2) which admits
of a packing of lubricating material-by this means-we make the machine self
lubricating and reduce the friction to a minimum.
We regulate the size of the material to be crushed fine or coarse by making the.
hitherto fast jaw moveable-and by means of the wedge block G-(see drawing in
fig. 1) fitted with adjustable screws-the jaw H (see drawing in fig. 1) can be
moved backwards or forwards as required. This arrangement is in combination
with other methods, used in machines of the type forming the subject of the
invention.
Having now stated the nature of our Invention we claim the following
advantages in our stone breaking and ore crushing machines
First. The novel method of running the eccentric shaft through the swing jaw
of the machine and by that means obtaining a powerful and direct action and
dispensing with all intermediate connections whatever.
Second. The novel arrangement of recessing the bearing in the jaw to receive a
lubricating packing-thus reducing the friction to a minimum.
Third. The novel manner of regulating the machine to crush any size required.
