To aZZ whom it may concern:

Be it known'that I, ALBERT (J. GALKINS, a citizen oftheUnited States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented and discovered a new and useful Improvementin Grinding- Machines; and I do hereby declare the followview of the machine, taken upon the line d (Z.

of Fig. 1. I Fig. is a cross-sectional view of the machine, the rocker-arm elevated and the disks in position to be cleaned; and .Fig. 11 is a sectional view of parts in detail.

Similar reference numerals and letters refer to like parts throughout the several views. i

The reference-lettersA B denote the bedplate or support for the machine. The letter A refers to the longitudinal portion of the said support, having horizontal and vertical parts, and the letter B indicatesthe end ortion of said support. The rectangular, ot- 7o tomless, and 0 en-top box, C, having side pieces D D" an end pieces E E, rests upon the portion B of the bed-plate or' support A B, which is preferably constructed of castiron and made integralwit'h the said'side pieces D D and end pieces E E of the box. The side pieceD is cut out or circularly recessed at F, as shown upon Figs. land 10 of the drawings, the said recess F to allow unim eded oscillation for a portion of the roc er-arm carrylng the driven shaft when 1 the machine is in operative position as illus- I trated upon Fig. 1 of the drawings. The reference-numerals 2 2 denote lugs projecting upwardly, one from either end of the said vertical part of the'longitudinal portion A ofthe support or bed-plateA B of themachine, havlng elongated perforated heads 3 3 ,pon the ends of lugs, in which perforated heads the bar or rod 4 vibrates or rocks. The said bar or rod extends beyond the ends of the portion A of the support or bed-plate of the machine. On the rod 4 the rockerarm 20 (hereinafter specifically mentioned) 'is secured and is adapted to be swung up- 5 ward and rocked, respectively, as illustrated upon Figs. 10 and 1 of the drawin s. The numeral 50 represents the gear-'shie d. The end of the said rod 4. adjacent to the opentop box 0 is screw-threaded at '5 to receive TOO the hand-nut 6 and the angular wrench-nut 7 in order to longitudinally. adjust the said rocker-arm supporting the driven revolving shaft21, carrying on one end thereof the movthe invention, such as will enable others skilled in the art to which it 'appertains to makeand use the same. v

This invention relates-to improvements in grinding-machines; and the objects of my improvement are, first, to construct disks or for pulverizing-ores or other material that or grinding-surfaces ,second, to manufacture machines for grinding samples of ores 01:

mg varied ingredients and different propormixing of the ingredients of one sample with the ingredients of another sample, and, third, to provide machines with grinding disks that can be quickly separated and cleaned and again conveniently brought together for panying drawings, to the figures, reference numerals, and letters marked thereon.

The invention consists, essentially, in the construction, combination, and arrangement of the several parts, as will be hereinafter fully described, and specifically pointed out in the claims.

I attain the objects above referred. to by the construction, combination, and arrangement of parts illustrated the accompany- Figure 1 is a plan view of the machine, a part of the gear-shield broken away. Fig. 2 is a plan view of the rotary grinding-disk removed from the driven shaft. Fig. 3 is a sectional view of the rotary disk, taken on the line a a of Fig. 2. Fig. 4 is a plan View of the stationary disk removed from the frame or stationary disk, taken on the line b b of Fig. 4. able revolving disk 22, adapted to be brought 1o 5 Fig. 6 is a view in elevation of the machine, in contact with and grind against the face of the parts thereof in operative positions. the stationary disk 23, secured, within the "F1g. '7 is a plan view of the cam upon the box 0, to the side piece D thereof, by means driven shaft and. a portion of the gear for of screw-bolts 29 29,, which enter screwoperating said cam. Fig. 8 is a sectional view threaded holes 39 39 in the outer face of the no of the cam and. rivi ng-gear, taken upon the disk 23. Upon the opposite end of thebar or 'line a c of Fig. 7 Fig. 9 1s a. cross-sectional rod 4. farthest from the open-top box 0 the drivinggear 8 and the pulley 9 are keyed to a flange-sleeve 12, which revolves upon the said rod or bar 4, the pulley 9 having a handle 10 secured thereon. The pulley 9, if required, may be driven by a belt passing over the driving-pulley of a motor. (Not necessary to be shown.) The driving-gear 8 meshes with the gear 11 upon the end of the driven shaft 21, journaled in the free ends 24 24 of the rocker-arm 20, which is secured to the said rod or bar 4 by means of pins 25 25, the said rod or bar turning within the perforated heads 3 3 as the said free ends 24 24 of the rocker-arm 20 are elevated or depressed by a earn 36. One end 24 of the rocker-arm is rovided with a handle 12, by means of which the said rocker-arm is rocked or turned upward, as shown upon Fig. 10 of the drawings, in order to clean the grinding-disks 22 20 and 23. The reference-numeral 13 designates the hopper, which is preferably constructed of cast-iron and made integrally with the said side piece D of the box C. The openin 14(shown in dotted lines upon Fig. 6 2 5 of the rawings) communicates with the perforation 15 in the stationary disk 23, through which opening 14 and perforation 15 the material to be ground or pulverized passes through the hopper to the grinding-surfaces 0 of the

disks

22 and 23. The material after being pulverized or ground falls into a suitable vessel or pan (not necessary to be shown) placed under

disks

22 and 23 within the box 0, and it can be quickly and conveniently 3 5' removed or replaced under the said disks when desired. The movable revolving grinding-disk 22 is secured upon the end of the driven revolving shaft 21 by means of headed screw-threaded bolts 17 17, as illustrated upon Figs. 1 and 6 of the drawings, which pass through the plate 16, fastened upon the said shaft 1n any suitable manner, the said bolts being fastened into the screw-threaded holes 18 18 in the outer face of the grinding-

disk

22, 4 5 as shown upon Fig. 3 of the drawings.

Keyed or otherwise secured upon the driven revolving shaft 21 is the gear 30, adapted to mesh with the gear 32, which revolves upon the stud 34, projected from and secured to the rocker-arm 20. The

gears

32 and 33 are secured together.

The cam 36 and the gear 37, the latter keyed upon the hub 38 of the former, both cam and gear mounted loosely, revolve struction and equivalents thereof that come 5 5 upon the drivenshaft 21, as illustrated upon within the scope of my improvement as 120 Figs. 1, 7, and 8 of the drawings. The gear herein shown and described, and illustrated 37, splined upon the hub 38 of the cam, upon the drawings appended hereto. meshes with the gear 33 upon the projecting Having described my invention, what I do stud 34, and the cam contacts with and reclaim, and desire to secure by Letters Patent,

berof revolutions of the cam 36 compared with the number of revolutions of the shaft 21, actuated by the driving-gear 8, of far greater dimensions than the gear 37. Besides, the said large driving-gear 8 meshes with the gear 1 1 ,ofless dimension than the cam-gear 37 Thus it will readily appear that the speed of the cam and its gear 37, revolving independently of but upon the shaft 21, is greatly diminished in speed compared with the speed of the said shaft, on which the said cam and its gear 37 are loosely mounted. The different rates of speed which the shaft 21 and the cam 36 travel, the latter against the periphery of the roller 42, cause the movable re- 0 volving disk upon the shaft 21 to describe an ever-changing orbit eccentric to the circumference or imaginary orbit described by the stationary disk. The orbit of the former, the movable revolving grinding-disk, is an ever- 3 5 changing orbit relative to or compared. with the one fixed orbit described by the circumference of the stationary disk. The orbit described by the movable revolving disk compared with that of the stationary disk is one 9 that changes or departs at every point thereof relative to the orbit of the circumference of the stationary disk. Theformer does not coincide with the latterthat is, a section of the orbit or any portion thereof is not coincident with any portion of the are described by the circumference of the stationary disk.

It will readily appear from the foregoing description, when read in connection with 1 0 the drawings hereto appended and made a part of the specification and claims, what is the operation of my machine, and further description of the manner of operating the machine is deemed unnecessary. IO 5 It is obvious that many variations and changes in the details of construction, combination, and arrangements of my invention would readily suggest themselves to persons skilled in the art and still be within the spirit I 10 and scope of my improvement.

I do not desire to confine this invention to the specific construction and arrangements of parts herein shown and described, and the right is reserved to make all changes in and 1 5 modifications of the same that come within the spirit of this invention; but I do desire to secure as my invention all features of con- 6o volves upon the roller 42, which also revolves 1s- 1 5 upon the projecting pin 41, secured to the 1. A grinding-machine comprising a starocker-arm 20.
