EUGENE L. SAN BORN, 0F MILWAUKEE, YVISCONSIN, ASSIGNOR TO SMITH ENGINEERING WORKS, OF MILWAUKEE, WISCONSIN, A CORPORATION OF WISCONSIN.
CRUSHING-MAOHINE.
Application filed November 14. 1917.
To all whom it may concern:
Be it known that I, EUGENE L. SANBQRN, a citizen of the United States, residing at ltlilwaukee. in the county of lVIilwaukee and State of Wisconsin, have invented a certain new and useful Improvement in Crushing- Machines, of which the following is a specification.
My invention relates to improvements in gyratory crusheis and has for one object to simplify the gyratory crusher. Another object is to provide means whereby the position of the crushing head in the hopper may be adjusted with a minimum of difiiculty in order to compensate r'or wear or change of adjustment. Another object is to provide a crushing machine wherein there will be a minimum number of places where clearance must be left in the line of crushing pressure.
In the past it has been proposed to use a crushing machine of general type wherein the rotating eccentric sleeve was surrounded by a cylindrical sleeve and wherein the crushing head is slidably mounted upon the cylindrical sleeve. In order that the crushing head may move longitudinally along the sleeve clearance must be left. Experience shows that when you use a type of machine wherein there are a number of loose fits in direct line with the crushing pressure a pounding or hammering will develop which results in battering or peening the head liner which thus wears larger than the bore. worse and before long the whole bearing is battered to pieces. By eliminating one of the loose fits this pounding is minimized.
In my device I make the cylindrical sleeve and the crushing head integral thus doing away with the clearance and stifi'ening the parts without increase in weight. I protect the eccentric sleeve by carrying an integral extension down from the crushing head into the oiling chamber and putting the crushing head into engagement with the eccentric sleeve only throughout an intermediate part of its length so that there is room for upward or downward adjustment of the cruslr ing head with respect to the eccentric sleeve without decreasing the bearing surface oft sleeve or head.
My invention is illustrated more or less diagrammatically in the accompanying draw- Specification of Letters Patent.
The result is that the pound gets Patented July 8,1919

ing which is a vertical section through the machine.
A is a crushing hopper mounted on a base A and provided on its interior with a crushing lining A the whole being mounted upon a foundation A. A is a. lower spider secured to the base and in this instance integral with the base of the crusher and adapted to carry the central shaft A which is secured to it and supported at its upper end by the upper spider A which is integral with the feed hopper A secured to the crushing hopper A by the bolts A.
B is a drivin shaft upon which is mounted the belt pu ley B adapted to be driven by any suitable source'of power not here shown. 13%, is a miter pinion on the shaft B rotating in the oil pocket B. It is in mesh with the miter gear B on the eccentric sleeve B which in turn is mounted for rotation upon the fixed central shaft A and is supported at its lower end upon the thrust bearing B.
C is a crushing head floating upon the eccentric sleeve B and in rotatable relation therewith. -It is adjustably supported upon the ring C by the adjusting screws C This ring C is slidably supported on a bearing ring' C provided with a packing washer C and having inclined oil and dust scraping edges as indicated. This bearing ring C is supported on the spider A and forms with the ring C and the cylindrical extension C extending downwardly from the crushing head the upper boundary of an oil chamber in which most of the working parts are con tained. This bearing plate C isheld against. rotation on the spider and the walls of the oil chamber by means of pins C. C is a resistant crushing shell preferably removable and made of manganese or similar durable material. It may or may not be corrugated or folded. If it is removable on the crushing head as indicated it will be held in position thereupon by means of a holding bolt C engaging lugs C on the shell and drawn up by means of nuts C engaging shells C on the head. Under some circumstances this shell could be made integral with the crushing head by merely chilling the outer surface of the casting. Under ordinary circumstances, however, on high duty work the manganese shell is preferable because it lends itself more readily to renewal. If the manganese shell is dispensed with the crushing head is cast solid so that its outer shape is the-same as that of the manganese shell.
I) is a main lubricating supply pipe leading from a pump nothere shown through one arm ofthe spider A into a passage D This passage communicates with an annular ring D about the upper end of the central shaft. A radial passage D communicates at one end with the grooves I) at the other end with the central passage D which in turn communicates by means of radial passage D with an annular groove I) in the central portion of the fixed shaft. Oil forced through this system finally comes; out into the groove D and moves up and down the central shaft lubricating the bearing of the eccentric on the shaft. D is a passage through the eccentric always in register with the groove D whereby the hearing between the eccentric and the crushing head may always be lubricated. Any oil which passes up on the inside of the eccentric will pass over the top'and down to the chamber D formed betweenv the packing ring D and the top of the crushing head. This packing ring D s'lidably engages a packing surface- D on the upper portion of the crushing head so as to make a sub stantially oii tight joint. The pressure is exerted uponthis packing ring to assist in the oil tightness of this joint by means of the screw D which completes a. firm seating of the packing ring on the upper end of the crushing head. The oil which passes down both outside and inside the eccentric sleeve passes finally into the oil chamber at the base ofv the sleeve. The oilinside the sleeve passes out and lubricates the thrust bearing supporting the eccentric. All the oil joins to lubricate the miter gear and pinion and then runs off through the pipe D to the reservoir D The bearings'E E in which the driving shaft B rotates are oiled by an oil duct branching off from the pipe D discharging into the chamber E between the bearings. Thence the oil works both ways, some of it in the oiling chamber B at the foot of the eccentric sleeve and also some of it in the chamber E where the miter pinion E on the shaft B drives the miter gear E on a pump shaft E whereby the pump driving mechanism is kept lubricated. Thence the oil returns by means of the pi )e E to the pipe I)" and thence to the reservoir.
The use and operation of my invention are as follows:-
The material to be crushed is fed into the crusher through the feed hopper from above and passes into the crushing hopper where it is crushed by the gyration of the crush ing head. The crushed material as it lee-- comes small enough falls out at. the bottom through the aperture between the crushing head and the hopper walls. Thisaperture may be kept of uniform size as the crushing head or the crushing walls, wear, by raising the crushing apron by means of the adjustable nuts provided for that purpose, or the same adjustment may be to provide a change in the size of product; making the aperture smaller will result in finer crushing and making it larger will result in larger crushing, the material being allowed to pass from the machine as soon asit is of a size small enough to pass through the aperture.
The sleeve extending downwardly from the crushing head passes through the supporting ring as indicated and oil is kept in and dust is kept out by means of the packing between the sleeve and the ring whereby the crushing head is free to move up and down when the adjusting screws are ma nipulated without exposing the eccentric sleeve and without making it possible for oil to escape from or dust enter into the oiling chambcr.
