ARTHUR L. FISH, OF SAN FRANCISCO, CALIFORNIA.
MACHINE FOR PULVERIZING ORES, 80c.
SPEGIFICATION forming part of Letters Patent No.'259,375, dated J'une13, 1882.
Application filed March 25, 1882.
To all whom it may concern Be it known that I, ARTHUR L. FISH, of the city of San Francisco, county of San Francisco, and State of California, have invented a new and useful Machine for Pulverizing Ores, Rock, and other Hard Substances and I do hereby declare that the following is a full and exact description of the same.
My invention relates to improvements in machines or apparatus for crushing and pulverizing ores, rocks, &c.; and the objects are to construct a machine in which the crushing and pulverizing are done ina more perfect and thorough as well as expeditious manner than has been done heretofore in ordinary ore-crushers, and to keep all bearings outside of and away from the material pulverized, except the revolving roller, which does the pulverizing.
The invention consists in the construction and arrangement of the different parts, as will be more fully described hereinafter, reference being had to the accompanying drawings and the letters of reference marked thereon.
Like letters refer to like parts in the several figures of the drawings, in which- Figure 1 is a vertical cross-section of my improved machine, with parts in elevation. Fig. 2 is a transverse section of the same 011 line a: a; of Fig. 1. Fig. 3 is a side view of one of the disks.
In the drawings, A B is a suitable frame, upon which is journaled the shaft S, having a cranked or curved part, S, for the purpose of clearing the roller R, and permitting a larger roller to be used than could be done if a straight shaft were used. To the shaft S the disks F are secured by keys or otherwise, and are provided with slots or openings to receive the sliding boxes K, to which are attached the rods I. 'Upon these rods are arranged springs or buffers G, of rubber or metal, and they are held in place by washers and nuts T. These springs impart a proper tension to the roller at all times, and also add to the crushing capacity. In the boxes K is journaled the shaft E, upon which the. crushingroller R is secured, and collars L on said shaft prevent endwise or longitudinal motion. The sides N of the casing of the pulverizing-machine are provided with screens P, through (No model.)
which the fine material can pass. Between the sides N is bolted the annular ring-die J, made preferably of steel, chilled or other hardened metal, and on the outside of this die is secured a strong metal band, M, to strengthen the die and guard against accidents by breakage. The centralflanges, Q, of the casing serve to close the openings and prevent the material from escaping. A pulley, V, imparts motion to the disks F and crushing-roller B. This roller R is slightly rounded or convexed on its face, and the die J is correspondingly-concaved. To the upper side of the casing is bolted a hopper, H, into' which the ore, rock, or other material is fed from an ordinary rockbreaker, and falls on both sides of the roller B into the machine, the hopper being provided with a double-inclined bottom to guide the material. The springs or buffers connected to the boxes of the roller-shaft will impart a quicker action to the roller and assist in overcoming friction in the movement of the sliding boxes in the slots or openings of the disks F as they slide in and out, and according to the size of the material passing between the crushing-roller and the annular die. If it is desired to resort to wet crushing or pulverizing, water may be admitted through the hopper with the material, or through the casing near the bottom. If it is to be used for drycrushing, an air or exhaust fan may be connected to one or both sides of the coveringscreens.
It will be readily understood that I do not confine myself to the size of the rollers or num= ber thereof, as one, two, three, or more rollers can be employed; and the shaft S may be made straight instead of cranked, and the casing and other parts made suificiently large to per mit the rollers to clear the shaft. Another modification would be to have but one disk, F, and allow the rollers to overhang on the end of the roller-shaft, while the other end of said shaft would extend into a trunnion-box, and the driving-shaft can then extend through the entire machine.
Having thus described my invention, what I claim, and desire to secure by Letters Pat= ent, is-
1. In a pulverizing-machine, the combina tion of the crushing-roller R, shaft E, slotted F, shafts S and E, sliding boxes K, rods I, and disks F, sliding boxes K, rods I, and springs springs G, all arranged substantially as shown or buffers G, as and for the purpose specified. and specified.
2. In a pulverizing-machine, the combina- In testimony whereof Ihereby aifix my sig- 5 tion of a crushing-roller, shaft E, slotted disks, I nature in presence of two witnesses.
means for rotating the same sliding boxes, I adjusting-rods, springs or liuflers, and the ARTHUR FISH ring-die, substantially as set forth. \Vitnesses: 3. A pulverizing-machine comprising cas- LLOYD KELEHER, :0 mg N, annular die J, band M, slotted disks J. W. HAMILTON JOHNSON.
