Patenten N or. feet, 1914.
Application filed January 31, 19M. Serial No. 815,869.
To alt i12/ima it may concern Be it known that l', Rossana l?. CoLinNs, a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented a new and useful Gravity OrefCi-usher; and l do against a central axle or shaft or spindle,
which supplied with a. plurality of sharp pointed or j agged pieks or teeth. As the ore y falls against this axle or shafting, it 'is thor- 20 oughly broken and crushed by said picks. As the ore leaves the axle or shaft and falls against the inner circumference of the cylinder under the axle the same is further lroken and crushed bythe teeth of the cylin el'. i i
' One of the features ofthe` invention is that the axle or shaft comprises'a. core memloer having.,r a series of bands, from which the sharp jagged points extend.
Another feature ofthe invention. arethe rake-like teeth of the inner circumference of the cylinder, which teeth are slightly curved in the direction in which the cylinder rotetes, for the purpose of conveying, the
sllarger and heavier portions of ore or quartz to a position relative to the axle or shaft Where the same may be dropped or dumped upon the large cent'al axle, thereby crushing and breakingr the or@ hy the jagged 40 point, and after falling,r to the bottom of the cylinder again, they are picked up and returned, in order to be dropped upon the central axle again. This process continues as .long as the cylinder is revolved, or until the 4b, ore is ground to the desired mesh.
Another feature of. the invention is the provision of outlets for the crushed ore, said outlets having perforated plates, and mov Y able perforated plates adjustable with relation to the first plate, whereby the perforan tions may he enlarged or restricted, so as to permit of the discharge of diilterent grades ofcrushed ore.
l'n practical elds the details of construc- 55 tion may be subjected to alterations, falling Within the scope of what is claimed.
The invention comprises further features and combination of )a1-ts, as hereinafter set forth, shown in tie drawings and claimed. i "ne ln the drawings: Figure l is a View in j ierspectire of the cylinder showing the central axle or shaft applied. Fig. t2 is a lon-f gitudinal sectional view on line 2-2 of Fig. l. liig. 3 is a transverse sectional View on line --l of Fig. l. Fig. et is a detail View, showing the c operating perforated plates of the discharge opening. Fig. 5 isa detail vieu' showing the jacket 7. j i
Referring more particularly to the draw- '70. ings-1, 'l designates the cylinder, which may he constructed of any suitable n'iaterial und in any suitable proportions. This cylinder 4is constructed of beam sections l fitted to` gether 'to foi-1n a perfect cylinder, said` sec 75 tions being preferably wood or othc'nsuit able fiber. The heads 3 and 4 of thecylin d .f are likewise constructed of wood or otler` suitable fiber, of tough quality. The inner circumference of the cylinder may be lined gc, throughout with cement, ,heavily reinforced with scrap iron of various kinds, the cement being designated by the numeral 5 and the scrap iron designated by the numeral 6; or the inner circumference may be incesed in a e jacket 7, as'shown in Fig. 5, of malleable ironor steel constructed of blocks or cast, ings. The inner ci rcumferenee of the cylinder is constructed lwith sharp points or spurs, secured to the outer wall ofthe eylinder as shown at 8, said points or spurs being designated by the numeral 9, and are; slightly curved in the direction in which the cylinder rotates or revolves. e Said points or spurs project through the lining. of cc 95 ment and scrap iron or steel in one instance, and in another they project from the incasel ment of steel or iron. At a suitable location the Wall of the cylinderl is constructed; with an opening 10 having a closure 11. which may be removed so that the ore and the like may be placed in the cylinder. Also arranged at suitable locations in the Wall of the cylinder are openings 12 having,r stationary perforated plates, said perforations being of a. triangular contour as shown. Cooperating With the stationary perforated plate are movable perforated plates 13, the perforations of which are of a contour corresponding with the perforations of the stationary plates, but reversely arranged. The movable perforated plate may he adjusted,
I so as tofbring fthe perforations of the mov- 2o spurs or picks 18 radiating'therefrom, 'inl able plates in and out of registration `With the openings to which the ore 1s inserted into as to permit of the discharge' ofdiderent meshes of crushed ore. The proportions of the openings to which. the oreis inserted into@ the cylinder and the proportions of the open-4 ings with the perforated platesmay be varied to suit the requirements. The contour and construction of the teeth, points or spurs of the cylinder may be changed to.suit Vthe requirement relative be handled. v
Mounted in bearings of the heads of .the cylinder is a shaft or axle A1.5, which comprises an inner-corel of any suitable material preferably wood or otheriiber of tough quality, which is incased in sections of steel jackets'o'r 'sleeves 17 haviinegy short points,
contact With which the ore is forcibly thrust,
v seas to be crushed or broken in smallpartinles, said ore falling from the inner circumference of the cylinder. The inner core is provided with pintles 19 at its ends-projectlng bevond the sleeves or jackets of the core. These `p intles are incased in steelA or brass jackets or sleeves 20, which in turn arev mounted 1n roller'bearings 21 as shown.-
Thc louter circumference of the cylinder at one end isjprovided with a band .of gear teeth 23, to which any suitable powermay be geared by the gear 24, so as to impart a revoluble movement tothe cylinder:' As the cylinder revolves the ore is carried around therewith to a vlocation over the central shaft oragile, where it is released and thrust i -'With force'down upon the sleeve castings or 'the lowerportion ofthe cylindfnf` In this -mannerthc fragments of ore are sufiiciently" jackets of the shaft in contact' with the sharp points thereof, then falling from the axle in contact with the points or spurs of reduced, softlnitd'the finer meshw'ill pass to a' locationabove the axle,l Where 'it isv l@ A' thro'fugh vthe perforations of the stationaryy and movable plate.4 When the ore i'sdropped `fronrtheaxle, to the lowenportionof' the cylinder-'Vit is again, picked up and carried again released and thrustdownagainst the tothe kind of ore to misera axle. The cycles of operations are consecu tively repeated until the desired mesh ofore is attained.
The invention having been set forth, what is claimedvas new and useful is:
providedw'ith an ore pulverizingv interior surface, a shaft on which said cylinder is mounted and, having sectional pulverizing means' cooperating with the first pulverizing means for crushing the ore, said cylindrical wall of the cylinder being' constructed of longitudinal beam sections' arranged .in
1. In combination, a revoluble cylinder sequence and removably united, said cylinder having cylinder" heads comprising segmental sections removably joined in sequence e and axiallyv on the shaft.
3. In combination, a revoluble cylinder comprising an' outer casing having a plurality of sharp teeth or spurs, and an inner casing composed of cement and scrap metal, v. an axle'mounted 1n bearmgs of the cylinder heads of the cylinder' and provided with pulverizing means, the teeth of the cylinder being curved in the direction of rotation of the cylinder, v'vhereby the ore may be car; ried to a-loeation 'substantially' above Vthe axle so that, the ore may be thrust by gravity down upon t Ae!pulverizing means thereof.'
In testimony whereof Ivhave signed my 'namelto this 'specification in the presence of two subscribing Witnesses.
