PROVISIONAL SPECIFICATION.
Improvements in Stamping and Pulverising Apparatus.
I, RICHARD RICHARDSON HUTCHINSON of Pear Tree House Seymour Place
South Kensington in the County of Middlesex, Engineer, do hereby declare the
nature of this invention to be as follows :-
The object of my invention is to utilise an electrical current for producing the
necessary movement and power to actuate stamps or pulverising apparatus
generally.
In applying my invention to an ore stamping apparatus of any type, I attach one
or more electric motors to the standards or frames of the machine, and either
couple the spindles of the armatures directly to the cam shaft, or interpose suitable
gearing. In order to protect the motor or motors from the metallic or mineral
aust, and water, incidental to the working of such machines, I enclose said motor
or motors in a suitable casing which may or may not be provided with louvre
openings for ventilation. As an alternative device I may, in such stamping
apparatus dispense with the cams and cam shaft, and cause the stamp rods to pass
through solenoids, the magnetic power of which is sufficient to raise them, the
operation of crushing being performed by the dead weight in falling, after the
current has been cut off. In order to cause the solenoids to alternately raise and
release the stamps, I provide a small electro-motor, in the main circuit, or in shunt
thereto. Said electro-motor operates a commutator and causes the solenoids to
be placed in or cut out of, the circuit alternately.
I provide suitable switches and governors for regulating the apparatus according
to the requirements, and may derive the necessary current of electricity from any
convenient source.

Improvements in Stamping and Pulverising Apparatus.
1, RICHARD RICHARDSON HUTCHINSON, of Pear Tree House Seymour Place
South Kensington in the County of Middlesex 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 :-
The object of my invention is to utilise an electrical current for producing
the necessary movement and power to actuate stamps or pulverising apparatus
generally.
In applying my invention to an ore stamping apparatus of any type I attach one
or more electric motors to the standards or frames of the machine, and either couple
the spindles of the armature of the electric motor directly to the cam shaft, or I
may interpose suitable gearing, and in the case of using a motor or motors in
combination with an existing stamping machine or pulveriser I enclose said motor
or motors by a casing which is preferably provided with louvre openings for
ventilation, and prevents damage by water, metal dust or the like.
As an alternative device, I may, in such stamping apparatus, dispense with
the cams and cam shaft for raising the stampers or pulverisers, and cause the
stamp rods to pass through solenoids, the magnetic power of which is sufficient

to raise them, the operation of crushing being performed by the dead weight
in falling, after the current has been cut off, and the solenoid de-magnetized.
In order to cause the solenoids to alternately raise and release the stamps, I
provide a small electro-motor connected to the main circuit preferably as a shunt
thereto. Said electro motor operates a. rotating commutator, and by making and
breaking the connections of the solenoids with the main circuit, causes these to
lift and release the stamps alternately.
I provide suitable switches and governors for regulating the apparatus according
to the requirements, the actuating current of electricity being derived from any
convenient source.
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,.
First. The combination of an electric motor or motors with a stamping or
pulverising machine said motor or motors being connected to and with the cam
shaft or shafts substantially as herein described and shewn.
Second. In a stamping or pulverising machine, the use of a solenoid or solenoids
for raising the stamps in combination with an electrically driven commutator for
making and breaking the electrical contact, substantially as herein described and
.set forth.
