EVAN \V. JONES, OF PORTLAND, OREGON.

ROCK-YCIRIUSHER.

SPECIFICATION forming part of Letters Patent No, 329,048, dated October 27, 1885.

Application filed March 12, 1885.

T0 aZZ whom it may concern:

Be it known that I, EVAN W. J oNEs, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Rock-Crushers, of which the following is a full, clear, and exact description, reference being had to the accompany ing drawings, forming part of this specification, in which Figure l is a perspective view of my improved crusher. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal sectional view on the line 00 w of Fig. 2. Fig. 4 represents details of the main shaft E, and Fig. 5 represents views of the crushingdies.

Similar letters of reference indicate corresponding parts in the several figures.

My invention relates to a machine for crushing stone, coal, quartz, iron ore, &c.; and it consists in the construction and combinations of devices, all of which I shall hereinafter fully describe and specifically claim.

To enable others skilled in the art to make and use my invention, I will now proceed to describe the exact manner in which I have carried it out.

In the said drawings, A represents the main bed-plate or frame, of any suitable dimensions, design, and material, mounted upon a foundation of stone or heavy timbers, as shown in Fig. 1.

Upon one end of the bed plate A, and formed integral therewith, is a bearing, A, adapted to receive the bolt D, which has a rounded end and enables the lever B to have a rocking movement, the purpose of which will be hereinafter fully developed.

Journal-boxes A are also formed on the bed-plate at the end of the machine, opposite the bearing A, and in these boxes is mounted to revolve the main shaft E, upon one end of which is keyed a fly-wheel, W, and between the journal boxes A on the said shaft E is mounted the pulley P, to which power is ap plied to operate the machine.

The shaft E is formed with a wrist-pin, E, arranged so as not to be parallel with the main portion of the shaft, but in such manner that a line running through the center thereof when the shaft is in position will strike the center of the spherical-ended bolt D, be-

Serial No.158,578. (No morlel.)

fore referred to, and as indicated by the dotted lines in Fig. 4. The object; of this construction is that the wrist-pin will always have a true and solid bearing in the box in the end of the lever B, regardless of the position of the main shaft. The spherical end of bolt D bears against a box or-plate, F, in-

V manner as to permit of ready adjustment when the lower point of said die has become worn by its contact with the material to be crushed.

As before stated, B is a lever, by the operation of which the material is crushed. This lever is of the construction shown in Figs. 1 and 2, and it is attached to the wrist-pin E" of the main shaft E by ajournal-box, B, so that it may have a rocking movement during the revolution of the said shaft, which movement is permitted by the bolt D engaging the opposite end of the lever and acting as a pivot or universal bearing upon which the said. lever turns.

Rollers H are mounted upon the crushing- .lever at its enlarged end and in a line transverse to the spherical end of bolt D. This is to prevent the lever from oscillating or rolling on the axis of the bolt, but at the same time permit the lever to have free movement in all other directions.

Within dovetailed slots in the lever B are suitably secured verticallyarranged crushing-dies H and I, the latter having straight faces while the former is of a configuration corresponding to that of the inner face of stationary die G, so that the material to be crushed, when placed in the space between dies G and H, is readily broken. As it approaches the lowest point of these dies, it becomes thoroughly crushed, owing to the fact of the die G being placed at an angle to the working-face of movable die H, which brings these two dies close together at their lower or discharge ends. The space between these dies being regulated by raising or lowering the stationary die G in the block A enables me to crush the material fine or coarse, as may be required.

The operation of my apparatus is as follows: Power is applied through pulley P and crankshaft E to the contracted end of lever B, the other end of said lever beingjournaled on the spherical end of pin D. One end of lever B being moved in a circle by the crank E, and the other end being held on the pin D, gives the lever wit-h the crushing-dies H and I substantially four distinct crushing movements during each revolution of the crank E, and

eat the same time that the pressure is on the rock the peculiar motion of the lever gives to the rock a wrenching or twisting strain,thereby breaking it much easier than could be done by direct pressure.

Having thus described my invention,what I claim asnew, and desire to secure by Letters Patent, ,is

1. In a crushing-machine, the bed-plate A,

.a wrist-pin for giving a rocking movement to the lever B, substantially as and for the purpose specified.

' 3. In a crushing-machina'the combination, with the bed-plate A, provided with suitable bearing-blocks, the stationary die G, and the shaft E, provided with a wrist-pin,.and the pulley P, of the bolt D and the crushing-lever provided with the rollers H and a vertical angular-faced die, substantially as herein described.
