To all whom t may concern:
Be it known that we, ANDREW J. CHRrsTY and EDWARD O. BENNETT, citizens of the United States, residing at San Francisco, in
the county of San Francisco and State of California, have invented certain new and useful Improvements in Ore Crushers and Granulators; and we do hereby declare the following to be a full, clear, and exact description of the 1o invention, such as will enable others skilled 1n theart to which it appertains to make and j use the same. A
Our invention relates to Crushers and granulators for ore, (or coal or rock,) and has for its i 5 object the construction of a machine for this purpose which shall be capable of reducing ores by a purely granulating process, without lamination or mashing of the particles of pre-4 cious metal, so that said particles shall, when 2o freed from the embedding quartz, possess the same shape and characteristics as when in the j quartz; also, that a greater per cent. of yield and a more complete separation of the valu# able matter will take place in the succeeding process of amalgamation. We accomplish these ends by the peculiar form and manner of operating thejaws. The form of thecrushing-jaws is such as to give a gradually tapering or reduced space between them at the top,
3o extendingdown about Onehalf of their height and terminating in a narrower but uniform curved space, one of the jaws being convex and the other concave for this purpose. These jaws are so operated as to cause the crushing y to be done in the upper contracting space, which portions of the jaws shall have considerable movementto and from each other, while the granulation is accomplished in the lower curved space where the jaws have but slight 4o movement to and from each other with a largely-increasedcurvilinearmovement,which increases the rubbing and granulating effect in the lower portionof the jaws while t-he mashing or flattening of thevaluable particles is entirely obviated.
The jaws have a single common center and receive motion from a cranked shaft in such manner as to cause their movement in the re"- quired opposite directions.
rlhe manner in which we construct and op- 5oV erate our device to produce the ends above indicated will be more fully explained in the following detailed description.
The accompanying drawingsillustrate what we consider thebest means for carrying our invention into practice. V
Figure 1 is a side elevation of our machine. Fig. 2 is a plan view of the same. Figs. 3 and,
4 are respectively front and rear views of the machine. Fig. 5 is a longitudinal section on 6o line .fr w, Fig. 2, the ends of the machine being reversed. Fig. Gisadetail view of the cranked shaft.
Similar letters of reference indicate corresponding parts in all the figures where they occur.
A is the xed framing of the Crusher, cer tain parts of which will be designated by modified characters, as may be required, in giving a detailed description of our invention. o
B is an eccentric shaft (the eccentrics being oppositely disposed thereon) mounted in bearings a a on standard A A of frame A.
C is a fixed shaft mounted upon studs or standards A of frame.
D and DX represent the crushingj aws, one of which, DX, is pivotally mounted on the fixed shaft C, while to the other, D, are pivotally attached the yokes E, one on each side, by means of pivots or shafts h h', extending 8o through said jaw, the shaft h also extending through slots le* in the ends of the lower limbs of said yokes. These yokes are also pivotally mounted on the fixed shaft C and serve to hold the jaw D in proper relation to the jaw 85 DX, whereby said shaft becomes the center of motion for both jaws. The slotted ends of the lower limbs of the yokes E are provided with set-screws it, (Figs. 1 and 3,) whereby proper working distance between the jaws 9c and compensation for their wear may be maintained.
The jaws are operated from the eccentric shaft B by means of the pitmen b and b b atA tached thereto, the former being coupled to g5 the jaw D preferably at or below the middle height thereof and the two latter to the jaw DX at its top.
I jaws.
The cranks or ecccntrics on shaft B, as best shown in Fig. 6, are so disposed as to cause the jaws to move in opposite directions.
An analysis of the movements and operation of the parts thus far described will show that the jaws are caused to have aconsiderable backend-forth movement to and from each other with but little if any rubbing or vertical movement at their upper ends,while the action is reversed at their lower ends, and the rubbing or vertical movement is largely increased, while the opposing reciprocation is almost entirely absent. These effects are due tothe manner of coupling and mounting the The resultant function achieved by this movement is to crush and break up the quartz in the upper portion of the jaws,w hile the granulation is completed below without laminating or meshing the precious material, the partially reduced or broken lumps and eraggy particles of the quartz aiding to free the precious particles by Contact with each other without bruising or mashing the valuable particles. This effect is attained, to a considerable extent, by the manner of operating the jaws regardless of the shape thereof, and we may use the construction of parts thus far described with any form of jaw; but we employaform ofjaws which increases the utility of the machine in the direction above stated to a very great degree, and weprefer this form of jaw to the ordinary form for reasons which will now appear.
To the body portions D DX of the jaws we apply the faces D D", which are formed of steel or chilled iron. The faces are formed with inclined portions d di, which recede from each other at the top and converge to about mid-height of the jaws. From this point downward the faces of the jaws run practically parallel with each other, but are curved, as shown, one being concave, as shown at di, and the other convex, as shown at d4. With these forms of jaws the process of granulation without lamination is pursued in a most complete and perfect manner. The upper contracting or reversely-inclined portions are given a considerable movement to and from each other and have great crushing power, while this movement in the lower curved and parallel portions is scarcely noticeable, but aninverse curvilinear or reciprocating movement is olo-v taincd,whichtends to separate the precious particles from the inclosing quartz wit-hout laminating or mashing them.
The jaws may be smooth or corrugated.
If desired, fly-wheels maybe applied to the cranked shaft to secure steady movement.
Between the yokes E and the sides of the jaws we place side plates or cheeks,G G,which are made removable and can be replaced by others when worn out. rlhese serve both to steady and sustain the jaws laterally and also to keep the material under treatment between them.
Having thus described our invention, what we claim, and desire to secure by Letters Patent, is
l. The combination ofthe fixed shaft C, the jaws D DX, the yohes E, and means, substantially as described, for operating the jaws, the jaw DX being pivotally mounted on the fixed shaft, and the jaw D pivotally attached to yokcs E, which are also pivoted to the fixed shaft.
2. rlhe combination; with the fixed shaft (l, the jaw DX, and the yokes E, said jaw and the yokes being pivotally mounted on said shaft, of the jaw D, pivotally secured to said yekes, whereby it is held in proper relation to jaw DX, the eccentric shaft B, pitman b, connecting said shaft with one of said jaws at its middle height,and the pitmen b b,connecting it with the opposing jaw at its top, substantially as and for the purpose set forth.
In testimony whereof we affix our signatures in presence of two witnesses.
ANDREW J. CHRISTY. EDWARD O. BENNETT.
