ORE-CRUSHER.
SPECIFICATION forming part of Letters Patent No. 531,068, dated December 18, 1894. application filed March 26,1894. as No. 505,127. (No model.)
To all whom .it may concern.-
Be it known that I, AUGUST HENRY SCHIER- How, of San Francisco, in the countyof' San Francisco and State of California, have invented a new and Improved Ore-Crusher, of which the following is a full, clear, and exact The invention relates-to orecrushers, such as shownand described in the application for Letters Patent of the United States, Serial No. 494,512, filed by me December 23, 1893.
The object of the present invention is to provide a new and improved ore crusher, in
is obtained and the centrifugal strain on the thrust bearings of the crushing rolls is greatly reduced, to permit of driving the machine with considerably less power and without decreasing the capacity of the machine.
The invention consists of certain parts and details, and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.
Reference is to be had to the accompanying 'drawin gs, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is sectional side elevation of the improvement. Fig. 2 is a plan viewof the same. Fig. dis a transverse'section of the same on the line 33 of Fig. 2. Fig. 4 is an enlarged transverse section of the bearings for the crushing rolls on the line 44 of Fig. 1. Fig. 5 is aplan view of one of the endthrust bearings, showing it made in sections. Fig. 6 is a sectional side elevation of a modified form of the improvement; and Fig. 7 is an enlarged transverse section of part of the same on the line 7.7 of Fig. 6.
The improved ore crusher is provided with a circular pan A, having inclined sides, a feed spout A and a discharge spout A. for carrying off the crushed material; The pan Ais supported on a suitable foundation B, and in the sides of the said pan are openings covered byscreensA discharging into the drawings.
In the bottom of the pan A is arranged a circular die (J, on which travel the crushing rolls D,'adapted to crush the material placed on the said die 0. The crushing rolls are either fastened on the axles E, as illustrated inFigs. 1', 2 and 3, or are mounted to rotate loosely on the axles E, as illustrated in Figs. 6 and 7. Each axle E is journaled in the bearings F and G, of which the bearing F is located near the respective roll D, and is mounted to slidevertically in suitable guideways in a frame or table H, secured on the driving shaft Idisposed vertically and mounted to turn in suitable bearings in the machine. The other bearing G is provided with trunnions 1G, mounted to turn in suitable bearings in' the frame or table H, as is plainly shown in Fig. 4, so that the roll D can move up or down according to the amount of mais constructed in such a manner as to receive annular shoulders formed on the corresponding axle E, whereby all end thrust of the axle E is taken up by the corresponding bearing G.
As illustrated in Figs. 1, 2 and 3, the driv ing shaft I, is connected by gear wheels with the main shaft J, carrying pulleys connected by abelt with other suitable machinery for imparting a rotary motion to the said main shaft J. The latter transmits its motion to the vertical drive shaft I carrying the frame H, so that the latter in revolving with its shaft I, carries around the axle E, so that the rolls D roll off on the die 0, and thereby crush the material placed on the latter.
stream of water on the said screens A to prevent their clogging, and at the same time to wash thematerial through the screens into the circular outlet chute A In the modified form illustrated in Figs. 6 and 7, the shaft E for the crushing roll D is held in a vertically sliding bearing F, fitted in suitable guideways in the frame H, the outer end of the axle E being provided with a transversely extending pivot pin E mounted to turn in suitable hearings in the frame H, so-that the said axle E is free to swing up and down,but is prevented from turning. As previously mentioned, the roll D is mounted to rotate loosely on this axle E, so that the latter does not require turning except to be carried around with the frame H held on the shaft 1.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-- 1. In an ore crusher, the combination with a pan, and a vertical and rotary shaft, of a frame secured to the upper end of the said shaft, a vertically sliding hearing at each end of the frame, a trunnion mounted at each end of said frame, the trunnion at one end of the frame being opposite the sliding bearing at the opposite end of the frame, parallel shafts mounted in the said bearings and trunnions, i
and a crushing roller on one end of each shaft, substantially as described.
2. An ore crusher, comprising a ring-shaped pan provided with screen covered openings, a central vertical and rotary shaft projecting above the pan, a frame secured to the upper end of the shaft, a vertically sliding and a pivoted bearing at each end of the frame, the sliding bearings being opposite the pivoted bearings, parallel shafts mounted in the said bearings, a crushing roller on one end of each shaft, and a scraper secured to the frame and projecting into the pan, substantially as described.
3. An ore crusher, comprising a ring-shaped pan provided with screen covered openings, a vertical and rotary shaft, a tank supported on the upper end of the shaft, a pipe leading from the tank to the pan, a frame secured to the said shaft below the tank, a vertically sliding and pivoted bearing at each end of the frame, two parallel shafts mounted in the said bearings, a crushing roller on one end of each shaft, and a scraper secured to the frame and projecting into the pan, substantially as herein shown and described.
