Improvements in Stone and Ore Crushing and Granulating
Machines.
I, SAMUEL MASON of Brandon Street Leicester in the County of Leicester
Engineer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement
My invention relates to a breaker & granulator wherein a movable jaw 18
oscillated or moved backwards & forwards to give a cracking motion, or moved
cicularly to give a granulating motion, the said moveable jaw being worked in
proximity to a fixed jaw.
I will describe my invention with reference to the accompanying drawing.
The framing A of machine may be of any suntable character & in the fiout end
of which is supported a fixed jaw B, in front of which a moveable jaw C is
suspended upon an eccentile or crank shaft D in the frame A, so that the said
Jaw C is moved in a circular manner by the said eccentric or crank shaft D.
When the said Jaw C is requned to be moved or vibrated backwards & forwards
only, the said vibration is effected by a lever E mounted at one end upon au axis F
carried by the framing A of the machine, the other end of the lever E is connected
by a link G on to another eccentric or crank shaft II, a toggle or thrust piece I is
interposed between the back of the said jaw C & in front of the lever E, the driving
wheels are put on the eccentric or crank shaft II which then gives the backward &
for ward movement to the said Jaw C.
When the said Jaw C is required to be moved circularly thereby giving a
granulating motion, the driving wheels are taken off the eccentric or ciank shaft Ef
& put on the eccentric or crank shaft D which then gives the granulating motion
to the said Jaw C.
The said Jaw C baving two grooves in the back, the toggle or thrust piece I 18
inserted in the top groove when a backward & forward motion is requiied-and
when a circular oi gianulating motion is requied the toggle or thrust piece I is
inserted in the bottom groove-therefore by simply changing the driving wheels
from one eccentric or clank shaft to the other & putting the toggle or thrust piece
into the top or bottom groove in the jaw C either a backward & forward motion or
a granulating motion is obtained as required.
Another toggle or thrust piece is put between the back of lever E, the block
piece J, which when moved by means of the wedge piece K, the adjustment of the
jaws is readily effected.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed 1 declare that what 1
claim 18-
First. A combined apparatus for breaking or granulating ores or other hard
substances, between the jaws of which the substances are broken or granulated as
hereinbefore described & illustrated by the accompanying drawing;
Second. The arrangement & combination of parts constituting the apparatus for
breaking o granulating ores or other hard substances hereinbefore described &
illustrated in the accompanying diawing.
