CUMMINGS I. COLBY, OF LANOHA PLANA, CALIFORNIA.
IMPROVEMENT IN MILLS FOR CRUSHING QUARTZ.
Specification formingpart of Letters Patent No. 58,777, dated October 16, 1866.
To all whom it may concern:
Be it known that I, CUMMINGS PIERCE 00L- BY, of Lancha Plana, county of Amador, State of California, have invented certain new and useful Improvements in Quartz-Mills for reducing quartz rock and other analogous substances; and I hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement without further invention or experiment.
The nature of my invention relates to the lowering of the cam-shaft used in stamp-batteries, and attaching to it eccentrics, surrounding each eccentric with a collar, from which extends an upright rod, through which a spring passes having a chuck upon the end of the spring, through which the stamp-stem passes, kept in place by set-screws, so that the stamp in falling will give a quick percussive blow to the quartz or ore.
In the drawings, Figurel is a front view of my mill; Fig. 2, a side view. Fig. 3 is astrap and set-screw through which the springs pass.
A A represent the frame, upon the crosspieces A of which the driving and eccentric shafts are placed. Upon the shaftB are placed the eccentrics B, of sufficient number to correspond with the number of stamps employed. Above the eccentric and driving shafts are placed string-pieces 0, with slots, through which the spindle or rod of the collar passes, attached to a vibrating bar, D, which operates in a loose joint in the upright standard of the frame A on pin Z. The spring a is placed upon the string-piece G, resting upon an iron plate held in place by a band, Z). This spring extends across the frame, passing through a slot in the collar-spindle and a band with set-screw extending to the stamp-stem 0, where it enters the chuck d, which is firmly held by a set-screw. This spring may be strengthened if desired by adding flat pieces of steel similar to that of an elliptic spring.
A movable strap, E, is attached to the end of the vibrating bar D, in which a forked washer, f, is placed, upon which the setscrew E operates,- pressing it down upon the spring and giving it tension. For the sake of convenience the movable strap may be attached to the vibrating bar at the same place and by the same means as the collarspindle by being placed in the slot of the spindle.
The frame of my machine should be braced and stayed in the best manner possible.
The ore or quartz is fed to the battery through an opening in the usual way. Motion is imparted by a belt attached to the driving shaft or pulley and the springs borne down by the setscrew E, which presses the washer f down upon the spring and imparts to it the pressure desired, giving it sufficient tension and also holding it in place; also, by this screw the stamps are all regulated and elevated on a line with each other for the purpose of cleaning up the battery.
By this arrangement of stamps and machincry for reducing ores or rock quick successive percussive blows are imparted, giving about threetimes the number of strokes to the pestles over those of the ordinary batteries. WVhere the tappets are placed upon the stamp-stems and operated by cams elevated above the frame, and that without a material increase of power, the ore is reduced to an impalpable powder in a much shorter time than by the use of the old machinery; also, by dispensing with the cams, and substituting therefor the eccentrics, the liability of breakage is avoided in case the machinery is driven a'little abovethe ordinary or usual speed; also, the springs in my machine being so constructed as to raise the stamps, the downward blow is imparted by the engine or power alone without lifting.
I contemplate that cranks and pitmeu may be substituted for the eccentrics, collars, and spindles in my machine.
I claim- The combination of the eccentrics B, with collars and spindles, and springs to, arranged to operate the stampers, substantially as described.
