JOHN D. OOPLEN, OF DENVER, COLORADO.

ORE-CRUSHER.

SPECIFICATION forming part of Letters Patent No. 399,600, dated March 12, 1889.

Application filed August 1, 1887. Serial No. 245,794. (No model.)

To all 1071 0111, it may concern:

Be it known that 1, JOHN D. GOPLEN, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Ore Crushers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in ore or coal crushers or pulverizers; and it con sists in a certain construction and combination of elements, which will be described fully hereinafter.

In the drawings forming a part of this specification, Figure 1 is a side elevation of my machine, and Fig. 2 is a section of the same, the section being on a line running longitudinally through the center.

A is the base-piece or bed of the machine, made of wood, iron, or other suit-able material, resting on and anchored to the ground or other solid foundation.

A A are bolsters or dead-wood secured to the base-piece for supporting the die-plate D.

B B are end pieces of suitable material, usually of wood, protected from undue wear by armor-plates, and O O are the side pieces. These parts are bolted or otherwise firmly bound together and constitute a tray or mortar, in which ore is crushed.

The die plate D should be of the hardest material practicable, as chilled iron or the like, and it, together with the base-piece, is provided with holes, as shown, for the discharge of the pulp to the trough E beneath. The side pieces, 0 O, are provided with slots O, for the purpose hereinafter explained.

B are chutes for conductin the ore to the tray or mortar.

F is a heavy segmental block, to which is secured by bolts or other suitable means a convex shoe, G. The block F should be of iron or other heavy material, and for convenience of handling and transportation is built up of sections dovetailed or otherwise secured and fitted together, as shown in Fig. 2 of the drawings.

H H are standards attached to the main block, and having cross-heads h 71 for the convenient attachment of guy-rods I I, for bracing said standards. The shoe G should be of similar hard material as the bottom or die plate, D, and should have a curvature somewhat greater than t-hat of the said die-plate.

A bar, K, connects the upper ends of the standards.

The parts composed of the block F, shoe G, standards H H, guys I I, and cross-bar K together constitute a muller for crushing and pulverizing the rock or ore.

On opposite sides of the block F are secured guide or staypins L L, having anti-friction rollers or thimbles thereon. These pins are adjusted to the slots C O in the sides of the mortar, and couple the muller with the mortar and confine it in a definite relation therewith. The sides of the block are provided with a plurality of sockets for the guidepins, so that they may be adjusted more or less away from the surface to give a slight draw or grinding motion along the face of the shoe. The muller is very heavy, and, while it may be made to vibrate to a slight extent around the guide or stay pins, it is permitted to rise and fall freely over the material, and its principal crushing effect is produced by the nearly direct action of the muller-surface upon the material being pulverized.

To regulate the weight of the muller, makeweights such as shown in dotted lines, Fig. 2, may be placed thereon.

Obviously the machine may be operated from any driving-shaft through the medium of a pitman, M, and the length of the thrust may be conveniently regulated by adjustable eccentrics on the driving-shaft. The stand ards are vibrated by any prime motor.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a concave bed having sides formed with vertical slots directly over the lowest point of said bed, a heavy or weighted muller having a convex face and guide or stay pins located on its sides at points near the convex face opposite the middle of the curve, and a rocking frame for corn nection with a prime motor, substantially as described.

2. The combination of a concave bed having pulp-discharge holes through the bottom, and having sidesformed with vertical slots over the lowest point of such bed, a heavy or Weighted muller having a convex face and provided with guide or stay pins located at the sides opposite the middle of its curve and near its convex face, and a rocking frame for connection With a prime motor, substantially as described.

3. The combination of a concave bed havin g sides provided With vertical slots over the lowest point of said bed, a heavy or Weighted muller having a convex face and verticallyadjustable guide or stay pins located at the sides at points near the convex face and the middle of the curve, and a frame for rocking the muller, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

JOHN D. COPLEN.
