Description
RICHARD F BRIDEWELL, OF SAN FRANCISCO, CALIFORNIA.`
SPECIFICATION forming part ofV Letters Patent No. 232,878, dated October 5, 1880.
Application filed February 13, 1880.
To all lwhom t may concern Beit known that I, RICHARD F. BmDEwELL, of San Francisco, in the county of San Francisco and State of California, have invented a new and useful Improvementyvin Ore Stamp Mills, of which the following is a specification.
My invention has for its object to provide an improved stamp-battery for the reduction of ores containing the precious metals, whereby the power required for operation and the cost of construction are reduced to a minimum.
It consists of a rectangular frame suitably braced, on which the workin g parts are caused to operate by means of cams, wheels, travel ing arms and levers, pulleys, and belts.
The upper ends of the stamp stems are curved, and are lifted and partially rotated by horizontal arms, an d at the same time the mortars are caused to be rotated, whereby a combined grinding as well as a stamping or vertical action of the stampers is had in the reduction of the ore to a suitable iineness for amalgamating with the quicksilver.
It also consists of an ore-feeding device, whereby the ore is fed to the stampers in an automatic manner, all of which, together with other details of construction, will hereinafter more fully appear.
I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure lis a front elevation. Fig'. 2 is a side elevation. Fig. 3 is a vertical sectional eleva tion; Fig. 4, a cross-section through hopper and feeding-chute Fig. 5, a vertical section through mortar and mortar-bed.
Similar letters refer to similar parts throughout the several views.
The rectangular frame A is suitably braced at B B and by cross-beams C C, upon which the head-blocks D D, which provide bearings for the drivin g-shaft D', by which the stamps are operated, are placed. The stampstems E extend up between the cross-beams C C to near the top of the frame, passing through guide-plates fixed to the beams. The ends of these stems or spindles are bent over and enter draw-bars F. The front portions of these draw-bars rest upon the top of the cross-beams, and the rear portions pass under the rear beam and are connected to bell-crank levers or arms F', having their bearings on a shaft, a, at the rear end of the head-blocks D D.
To the shaftingD' are connected cam-wheels D2, to which is attached a cam lever or arm, D3, which lifts the stampers by a rectilinear reciprocating movement at each revolution of the cam-wheels. This cam-lever is moved by a bell-crank lever, D4, similar to that which moves the draw-bar F, and this arm or lever is operated by the same rock-shaft.
The frame-work rests upon a suitable bedplate, G, and upon this foundation the mortars are caused to rotate by a belt-connection with the driving-shaft at the rear side of the frame. The upper face of the bed-plate is provided with steps or projections H, on which the bases ofthe mortars turn, an offset bein g made therein to receive the step. This step or projection may be rounding in form, and the opening in the base of the mortars be made to correspond. Power is communicated Ato the mortars by a belt, I, which connects with a pulley, I', on the driving-shaft I2.
The ore is fed to the hopper in front of the stam pers in the usual way, and the bottom of the hopper is divided by a vertical partition, J. Each of these spaces is provided with a movable bottom o1' drawer, J', which moves outward, or back and forward, by means of a rod, b, having a bent arm, c, connected to the front of the hopper and extending around the stamp stem or spindle, so that when the stampstem is raised it will carry the rod b with it and throw out the arm c against a cross-rod,d, in front of the sliding apron and draw it backward, which causes the ore-bodies on the apron to be carried forward and fall by their specific gravity into the mortars and under the stampers.
In operating with my ore stamp-mill, after IOG ing-shaft with the mortars imparts to these a continuous rotary motion upon their pedestals, so that the stampers at each stroke will give a blow at different points on the bottom of the mortar.
Having` thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-
l. The combination, in an orc stamp-mill, of the rectilinear reciprocating cam arm or lever D3, cam-Wheel D2, and bell-crank D4, all arranged to operate substantially as and for the purpose specified. l
2. In combination with an ore stamp-battery, the cam-Wheel D2, rectilinear reciprocat- 15 ing` cam arm or lever D3, and traveling arm or draw-bar F, whereby the stampers are raised and a half-rotary motion imparted to them at each revolution of the driving-shaft D', substantially as described.
In testimony that I claim the foregoing I have hereunto set my hand andseal this 26th day of September, 1879.
