GEORGE DOWNING, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO COLLINS EATON, OF SAME PLACE.
'IMPROVEMENT IN STAMP-MILLS.
Specification forming part of Letters Patent No. 191,521, dated June 5, 1877; application filed April 14, 1817.
To all whom it may concern Be it known that I, GEORGE DoWNiNG, of the city of Chicago, -iu the county of Cook, and State of Illinois, have invented a new and useful Improvement in Stamp-Mills. which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 3 is a sectional view on the line a: w, Fig. 2. O is the frame that supports my apparatus. pivot-bolt K, is the lever D. On the axle of the drive-wheel N is secured or formed the tapet M. This tappet M, revolving, depresses one end of the lever D. The friction between the tappet M and lever D is diminished by the friction-rollers L. The tappet end of the lever D being depressed by the tappet M, the lever turns on the pivot K, and the other end of the lever D is raised. On this end of the lever D is secured or formed the cross-piece B is a strap or cord fastened at one end to the stamp-shaft T by means of the bar and hoop S It. The hoop B iits into a recess or groove formed in the shaft T. The other end of the strap or cord B is attached to the axle of the ratchet-wheel Q. By means of this rachetwheel Q the strap is tightened or loosened, at pleasure. The ratchet-wheel Q is held at any set point by means of the catch F and spring G. The object of this cord B is to raise the sLamp-shatt T, to which is attached the stamp or head U. The object of the cord A is to pull down the stamp T U. The cord A is attached to the stamp-shaft T, and is tightened and loosened in the same manner as is the cord B. The end of the lever D is pulled down by the spiral spring I. The tension of the spring I is regulated by means of the screw-bolt H and nut t. I do not confine myself to the spiral form of spring shown, but I claim the use of any spring in this connection that will accomplish the desired purpose. This spring I is supplemented and re-enforced by the rubber block spring b, placed on the support a. I do not confine myself to a rubber spring, but claim the use of a spring in this connection of any form or substance that Secured to this frame O, by the will accomplish the desired result. On this spring b the tappet end of the lever D strikes when depressed. The revolution of the tappets M, by means of the drive-wheel N, depresses the tappet end of the lever D, and raises the stamp T U, the same being instantaneously returned again with a quick blow upon the bed or support W, by means of the springs I and b. The face of the crosspiece C being circular, and describing the arc of a circle in its movement up and down, the action of the straps A and B is in a directly vertical direction, both up and down, thereby doing away with friction on the shaft T in the journals c and la. X is the inclosure in which the ore or other substance to be crushed is placed, Where it is thoroughly pulverized by the pounding of the stamp U on the bed W. During this process a stream'of water can be let on to the pulverizing substance through the supply-hopper m. Through this same hopper the substance to be crushed is also supplied. When sufficiently pulverized the crushed substance passes through the sieve or screen Y into the sluice Z, where it is taken care of.
This apparatus can be worked by handpower by the crank h, or any other power desired, by means of the band or pulley-wheel f. The spring I, tappet M, drive-wheel N and f, and lever D, are essentially the same as in my rock-drilling machine, patented September 22, 1874, No. 155,186. I therefore make no claim on them in this invention, only in combination with other features different from anything shown in my rock-drilling machine above-named.
What I claim as my invention, and desire t0 secure by Letters Patent, is-
1. The lever D, constructed with a circularfaced cross-piece, C, in combination with the cords A and B and the ratchet-wheels E and Q, in the manner shown and described, and for the purpose set forth.
2. The lever D, constructed with the circular-face cross-piece C, in combination with the cords A and B, the ratchet-wheels E and Q, spring I, and the rod Y, in the manner shown and described, and for the purpose set forth.
faced cross-piece, C, in combination with the cords A and B, and shaft T, in the manner shown and described, and for the purpose set forth.
6. The shaft T, constructed with the head U secured or formed thereon,in combination with cords A and B, and lever D, as shown and described, and for the purpose set forth.
