UNITED STATES PATENT OFFICE.

. 7 IMPROVEMENTIN QUARTZ-CRUSHERS;

Specification forming part of Letters Patent No. 46,936, dated Mali'ch 21, 1865 nntcdatcd March 3, 1865.

To all whom it may concern:

Be it known that I, GEORGE K. Pn'rnnson, of the city and county of San Francisco, State of California, have invented a new and 1mproved Machine for Orushin g and Pulverizing Quartz, Stone, and other Hard Substances;

andlfdo hereby declare that the within is a "full,'clear, and exact description of the construction and operation of the same, reference being'had to the annexed drawings, making a part of this specification, in which- Figure 1 is an, elevation. Fig. 2 is an end 'view. Fig. 3 is a plan.

the form shown, or in such other form as will answer the purpose, and, connected by the bars D, making a strong frame. A A are two vibrating crushing-plates made in the form shown in. the drawings and provided w h journals at their upper corners, titted to work in the side of the frame -or boxes B B on the frame. I contemplate thatoue of the boxes may be madc movable on the frame to adjust thecrushing-plates to each other. The :crushing-plates are provided with journals K CK near their lower ed ges, which journals are provided with boxes connected by the rods E,

furnished with nuts I.- L, to adjust the plates To crush the materials coarseor fine, as re- -reql'lired. {The journals K K. are perforated,

- and the holes elongat d perpendicularly, so

that the rod E can vibrttc in them.

The

plate A has lugs I I on its back side, which lugs are perforated for the pin which passes through them and the connecting-rod H, which connects the plate to the crank G, which vibrates the plates when the machine is operated. The crank G turns in boxes on the sides D, and is provided with a pulley, F, for a band from some moving power to operate the machine.

The operation of themachiue is as follows: The power being applied to the crank-shaft G by pulleys, gearing, or any usual manner of working such machines, and by means of the connecting-rod H a Vibratory motion is transmitted to the crushing-plate A, which being connected with the crushing-plate A by means of the side rod E before mentioned a grinding and; crushing motion is "produced and the quartz ore or other substance being intoduced into the box formed by the .two crushingplates A A is reduced to any degree of fineness, according to the distance which the plates have been set apart. 7

In the construction of my machine I make the frame of iron, also the crushing-plates. To prevent these plates fromwearing out they are fitted with hard white iron shoes, which may be easily replaced when worn. By this arrangement I am not compelled to substitute new jaws, which in machines'of this magnitude are very expensive and weighty.

Having thus described my machine, whatI claim as my invention, and desire to secure by Letters Patent, is-

1. The crushing-plates A A, connected and arranged to operate substantially as described, for the purposes set forth.

2;. The mode described of connecting the journals K Kof the plates'A A, or such an equivalent device as will enable the operator to lengthen or shorten the rods which connect the journals K K.
