ivrAoHiNE 'FOR CRUSHING 05ans.4

ASpecification of Letters Patent No.

To all whom t may camerati Be it known that I, WM. HENRY PLUMB,

'of the city, county, and State of New York,-

have invented a new and useful Machine for Crushing Ores or other Hard Substances; Aand I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, rieference being had to the drawings herewith,

making a part of this specification, in

which-A Figure 1 is a plan. Fig. 2 a vertical section. Fig. 3 a cross section.v

The As represent a series of arms unitingin one common center which is fixed on the shaft B so as to rotate as indicated b-y the larger arrows. The shaft B is supported in the two arms C, C, which arms are suspended from the stationary pin D.

rlhe Es are rollers placed on the centers marked F so as to revolve backward as indicated by the small arrows when brought in contact with the material to becrushed, these rollers are placed alternately single and double. l

G is a trough of bid into which the material to be crushed is placed.

H is the hopper for receiving the material.

'To enable others skilled in the art, to

make and use my invention I will proceed.

to describe its construction and operation, viz: The series of arms marked A with the rollers marked E being suspended inthe arms C, C, which arms C, C, being hung from the center D, the face vof the rollers marked. E will be pressed against the interior surface of the bed G at a point determined by the relative position of the center D to the interior surface of the bed G which point of pressure can be adjusted in practice at pleasure. It is obvious that instead of the arms D a sliding motion can be given to the shaft of the rollers in a vertical 12,031, dated December 5, 1854.

or yinclined direction which will be a partial equivalent therefor but I prefer the arms D although I should consider the slide motion an equivalent of my device. The series of Varms marked A with the rollers markedly are rotated by means of aV pulley or geering in the direction indicated bythe large arrows,

thus bringing the face of the rollers marked y E gradually toward the interior surface of the bed G. The space between thev exterior line described by the rollers working from the shaft B and the interior line of the bed Gr, is continually contracting. Vhen the material to be crushed is thrown into the hopper H itis gradually reduced, the disposition of the weight of the rollers, arms,

etc., being such `that it exerts most pressure where it is most desired. The rollers marked E in their movement forward on the shaft B have also a movement Abaokd Nhat I claim as my invention and desire lto secure by Letters Patent, is-

The rollers upon the radial arms of the shaft connected with the movable arms or their equivalent and revolving in a basin whose inner surface is eccentric to the rollers,

shaft arranged and operating substantially inthe manner and for the purpose set forth.

WM. HENRY PLUMB.
