IMPROVEMENTS IN STONE BREAKING AND ORE CRUSHING MACHINES
Year: 1884

page_text: I, WILLIAM HENRY BAXTER of Albion Street Leeds in the County of York,
Engineer, do hereby declare. the nature of iny: said Invention for, "IMPROVEMENTS
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 reference being had to the accompanying Drawings and to
the letters and marks thereon:-
The object of my Invention is to construct a simple and effective machine for
reducing to the various degrees of fineness as may be required gold-quartz, copper-
tin-lead or other ores and which may also be used for breaking stone for
Macadam' or for other purposes.
. The arrangement or construction of the machine is as follows. Between suitable
standards or framework I mount a shaft on which is provided a cam or eccentric.
On the cam or eccentric is hung or, fitted (in order to be actuated thereby) an arm
which carries the crushing plate or jaw.
In front of this and between the
frainework is mounted a grooved, fluted, or plain roller which is caused to revolve
whilst the eccentric or cam on the driving shaft actuates the arm carrying the jaw.
This gives the desired motion to the toggle which is of ordinary construction
whereby, the required peculiar movement for crushing or breaking is given to the
jaw. The usual wedge arrangement is employed for adjusting or regulating the
distance between the roller and the jaw for producing various sizes of stone.
The face of the jaw is provided with teeth or flutes and the material may be fed in
between the roller and the jaw either through a hopper or other convenient
arrangement. The required rotary movement is imparted to the roller from the
driving shaft through suitable gearing.
When the machine is to be employed for breaking stones into more or less
cubical pieces I prefer to employ a roller with longitudinal grooves or flutes which
are at right angles to the grooves in the jaw; but when the machine is to be
employed for fine crushing I prefer to employ a roller with circular groves or
corrugations which are parallel to the grooves in the jaw; or a plain roller and a
jaw with a plain face may also be employed for this latter purpose.
Other parts of the machine may be of ordinary construction.
Sifters or riddlers or other receptacles may be employed under the jaw or roller
for separating the different sizes or for receiving the same.

page_text: And in order that my Invention may be more clearly understood reference is
given to the accompanying Drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation. Fig. 2 is a longitudinal section, and Fig. 3.is a plan
of a stone breaker or ore crusher. constructed in accordance with my Invention.
Fig. 4 is a part plan which will be referred to hereafter.
a is the framework of the machine which carries in bearings b the cam or
eccentric shaft c. On the cam or eccentric is hung or fitted the arm & which carries
the crushing plate or jaw f. In front of this and between the framework a is
mounted the grooved roller g which is caused to rotate whilst the eccentric or cam on
the driving shaft c actuates the arm & carrying the jaw f. This gives the desired
motion to the toggle h, and thereby also the peculiar movement for crushing and
breaking to the jaw f. The usual wedge arrangement i is employed for adjusting
or regulating the distance between the roller g and the jaw f for producing various
sizes of the material operated upon. The face of the jaw f may be provided
with teeth or flutes, though when preferred the teeth or flutes may be dispensed
with.
When the machine is to be employed for breaking stones into more or less
cubical pieces I prefer to employ a roller with longitudinal grooves or flutes as
shewn in Figs. 2 and 3, but when the machine is to be employed for fine crushing
I prefer to employ a roller with circular grooves or corrugations as shewn in
Fig. 4, or to use a plain roller and a jaw with a plain face.
Other parts of the machine not described or shewn may be of ordinary
construction.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same'is to be performed I declare that what
I claim is
1° The arrangement and application of the (grooved, fluted or plain) roller g in
combination with the arm d toggle h jaw f and substantially as and for the purpose
herein setforth.
2° The arrangement and combination of the various parts forming my improved
stone breaker and ore crushing machine substantially as and for purposes herein
setforth.
