ORE-SAMPLING MACHINE.
SPECIFICATION forming part of Letters Patent No. 682,528, dated September 10, 1901.
Application filed November 19,1900. fierial No. 36,990. (No model.)
To ctZZ whom, Lima/y concern:
Be it known that I, ALBERT O. CALKINS, of Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Ore-Sampling Machines, of which the following is a specification.
My invention is in thenature of an improved sampling-machine designed more especially for the use of assayers for rapidly and efficiently mixing and subdividing a quantity of pulverized ore, of which a representative sample may be desired, but which machine is also applicable for mixing and sampling or subdividing any kind of material, as is frequently required in the drug trade.
My invention consists in the peculiar construction and arrangement of the various buckets B C. The buckets are under the' hopper, and one of the buckets, O, is under the other, B. These buckets haveradial partitions, forming four divisions each. (See Figs. 3and 4.) Two of these divisions in each bucket are closed at the bottom and two are open. The open pockets in each bucket are directly opposite each other, as are the closed pockets directly opposite each other. The upper and lower buckets are substantially identical in size and arrangement of the divisions and openings, the only difference between them being the provision made for fastening the buckets one over the other. The upper one, B, has a central cone (9, that distributes the stream of ore, and it sits on and is fastened to a bevel-pinion b, which rotates it in one direction, While the other bucket O is suspended under its mate from another bevel-pinion c and is rotated by means of an intermediate bevel-gear d in an and is actuated by a crank E on a shaft pass ing through a frame-coupling F and the gearbracket D. The hopper which discharges into the top bucket receives four jolts or shakes to each revolution of the crank by means of a square cam e on the crank-shaft bumping a rod Gr, connected to the hopper A. The material being sampled is gradually jolted out of the hopper into the upper bucket on the apex of the cone, thence half of what is discharged into the upper bucket passes into the lower bucket. This half is again divided into half by the lower bucket. One quarter of the amount originally put into the machine is discharged from the lower bucket onto the floor or into a receptacle provided for the purpose and another quarter remains in the lower bucket. The four pockets in each bucket divide the ore into quarters, and the two diagonally opposite pocket-s being open allow the two diagonally opposite quarterings to pass through into the lower bucket, where the same office is performed. Thus the two diagonally opposite quarterings are held up and the other two quarterings, which are diagonally opposite to each other, are passed through. Thus it may be readily seen that this machine not only thoroughly mixes the charges by a centrifugal action, but accurately quarters it.
The machine is verysimple in construction. The buckets and hopper are of sheet metal, and the frame consists of a gear-bracket D, one end of which, F, unites two pieces of iron pipe S S, which form the standard. The bottom of the lower pipe fits into a floor-flange, which forms the base or footing of the machine. The hopper is pivoted to the top of the upper pipe, the four-phase cam e is cast to the crank, and the crank is fastened to the shaft of the intermediate gear, which shaft passes longitudinally through a hole or bearing in the gear-brack t D. An extended flange d is cast on the gear-bracket D, which prevents thecentrifugal force from scattering the material leaving the upper bucket and insures that it falls into the lower bucket. The upper edge of this shield extends upward and around the bottom of the upper bucket,
and the lower edge of the shield extends downward within the top of the lower bucket.
The central hub of the gear-bracket has a screw 8, that holds the vertical shaft 8, that forms the axis of the upper and lower bevel gears.
The shake-rod G is of steel and has an eye at its upper end connecting with the hopper, and the lower end makes a right-angle bend around the cam (see Fig. 2) and fastens to an adjusting-pin p or stud by means of an eye and cotter-pin. The lug Z, which holds the pin, isslotted vertically, so that the pin' carrying the lower end of the shake-rod may be slipped up or down, thus bringing the bent end of the shake-rod as near to or far from the cam as is necessary to give the degree of shake desired. The lower end and angle bend of the shake-rod are'tempered to prevent the rodpfrom bending and thusesc'aping the cam.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- l.v -In a mixing and subdividing apparatus, the. combination of abucket having a-series of compartments disposed around the center a portion of which are open at the bottom, and gears for rotating the bucket located in the vertical center of the bucket and inside the circle of the discharge-openings substantially as described.
2. Ina mixing and subdividing apparatus, the combination of two buckets arranged one above the other and having a series of compartments disposed in. a circle about thecenter a portion of which are open at the bottom, and double-actingv gears for rotating the buckets in opposite directions, said gears being located centrally inside the circle of the discharge-openings andv between the buckets substantially as described.
3. A mixing and subdividing apparatus comprising two buckets or chambers having radial partitions forming compartments a part of which are open at the bottom-and a part closed, the buckets being arranged one" above the other and discharging from one into the other, and means for rotating the buckets in opposite direction substantially asdescribed.
4. A mixing and subdividing apparatus, comprising two buckets having radial partitions forming chambers with openings at the bottom, and a double-acting gear arranged between and in central relation to the two buckets to rotate them in opposite directions substantially as described.
5. A mixing and subdividing apparatus comprising a standard made inv two sections,
acoupling connecting the same and formed above and outside the lower edge of the upper bucket, and arranged inside the outer wall of the lower bucket, substantially as described.
7. In a mixingand subdividing apparatus,
the combination of two reversel-y-rot-ating,
buckets having openings in the bottom, reversely-operating gears for thesame, an osoillating hopper arranged abovethe-buckets, a shaft for rotating the gears, anda-cam and rod forimparting motion from the shaft tothe oscillating hopper substantially as-described.
8. In a mixing and subdividing apparatus, the combinationof a frame D supported at one side and having acentral' vertical shaft 3, in combinationwitha bevel-gear b with closed hub 12 and pendent covering-flange b and asurmounting bucket having radial partitions and bottom, openings and a driving gear-wheel housed and covered by the flange 3 19 substantially as described.
9. In a mixing and subdividing'apparatus, thecombination of a frame D supported at one side and having a central vertical shaft 3', a bucket having a flanged gear-wheel attached to its lower side and mounted on the upper end of the shaft, a second bucket with gear-wheel attached tothe'upper part of the same and sustained upon the lower end of said shaft, and an intermediate driving-gear for rotating the two buckets in opposite directionssubstantially asdescribed.
10. In a mixing and subdividing apparatus, the-combination with a revolving bucket, and
itsgears and supporting-frame; of a hollow vertical standard with coupling F a horizontal drive-shaft passing through said coupling and'having a cam, arod operated upon by said cam, and an oscillating hopper connected tothe rod substantially as-described.
l1. Inamixingand subdividingapparatus, the combination with therotary'buckets, and the crank-shaft. having cam e; of the coupling-section F having stud Z with slot in its end, the pin p, the bent rod G' jointed to the pin and extending horizontally past the cam to be acted upon by the same, and thence extended upwardly, and an oscillating hopper connected to the upper end of said rod, substantially as described.
