Vitnesses AMPH070 LITHUG/f IIIC NY! BORNESPRJCrSS) IINITED STATES THOMAS A. GOOHBANE, OF JAMESTOWN, CALIFORNIA.
IMPROVEMENT m FEEDERS FOR QUARTZ-MILLS".
Specification forming part of Letters Patent No. 139,370, dated May 27, 1873; application filed June 10, 1872.
To all whom it may concern:
Be it known that I, THOMAS A. COOHRANE, of Jamestown, county of Tuolumne, State of California, have invented an I mproved}Feeder for Quartz-Mills; and I do 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.
My invention relates to an improved device for feeding quartz and othersubstances to machinery for crushing and grinding the same.
In order to explain my invention, so that others will be able to construct and operate the same, reference is had to the accompanyin g drawing forming a part of this specification, in which- Figure'l is a perpective view of my device.
A represents a hopper, which is supported in a frame, B. This frame should be situated close up to the machinery into which it is intended to feed the ore or other substances for the purpose of crushing or grinding it, and the lower side timbers 0 O extend out from spring-bar, H, from the tappet I on the stamp stem, or from some other part of the machincry, to cause the roller to revolve and thus move the endless band. The spring-bar H is supported in the end of a projecting timber,
J, and a spring, K, serves to lift it after each drop of the stamp. A turn-buckle, I, is inserted in the length of this rod so as to permit of the lengthening or shortening of the rod for regulating the amount of feed. The upper end of this bar rests beneath the tappet I, as shown, and consequently it will be supported in an inclined position in order that its lower end may engage with the ratchet g.
It is evident that instead ofthe ratchetore it is desired to feed. After passing through the lower opening of the hopper the ore is received upon the horizontal endless band F. As the stamp descends the tappet operates the bar H and causes the roller D to revolve,
consequently feeding the oreforward by moving the belt or band, thus automatically supplying the stamps with ore in the proper quantity.
The drop of the stamp determines the quantity of ore to be fed, as when a sufficient quantity of 'ore is beneath the stamp it will not drop so far and consequently will not operate the feeding device. But when the quantity of ore beneath the stampdiminishes the drop is greater and the feeding increased. A crank-wheel could be used for the rod to operate upon, if desired. This arrangement is quite simple and possesses the advantage of being able to feed very wet ore without trouble.
I am aware that the rod H has heretofore been used, and consequently do not claim it broadly; but I Having thus described my invention, what I claim, and. desire to secure by Letters Patent, is-- The hopper A, in combination with the horizontal endless belt or band F, operated automatically by means of the ratchet g, adjustable spring-bar H, and tappet I, substantially as and for the purpose above described.
In witness whereof I hereunto set my hand and seal.
