Specification of Letters Patent.
Patented J an. 3, 1922.
To all whom it may concern:
Be it known that I, MARCUS O. ANTHONY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Grinding Mills,of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
This invention relates to grinding mills, and more particularly to that class of mills wherein ore is crushed between two disks, one of which is stationary and the other revolved and reciprocated in contact therewith. Some of the objects of the present invention are to provide a machine that is simple. in character and consisting of few parts which are inexpensive to manufacture, while further objects and advantages will appear as the description proceeds.
In the accompanying drawings wherein I hav shown an illustrative embodiment of my said invention, Fig. 1 is a sectional View taken on the line 11 of Fig. 3; Fig. 2 is a rear end view of the machine; Fig. 3 is a front end view of the machine; Fig. 4 is a sectional view taken on the line 4-4 of Fig. 1; and Fig. 5 is a detail perspective view of the reciprocating mechanism.
Describing the various parts by reference numerals, 1 indicates a suitable base to which th fan casing 2 and the supporting table 3 are bolted. The fan casing 2 consists of a circular castin 4 provided with a discharge opening 5 an hingedly mounted on the front of the casing is the door 6 carrying the stationary disk 7 and the feed hopper 8 communicatin with the center of the grinding disks. llhe supporting table 3 may be a casting provided with suitable recessed dove-tailed rails 10-10 which are supported by the legs 11 and held in spaced relationship at the top by the base member 12. On one side of the supporting table there is positioned a pair of upright cam arms or guides 1414 which project upwardly above the rectangular reciprocating frame 15 which is slidably mounted on the rails 1010 and held in contact therewith by the clove-tailed members 16-16. A suitable gib 17 is placed in each dove-tailed recess to take up the wear therein. The main drive shaft 19 is journaled in suitable bearings in the support 27 and legs 1111, and keyed thereto at the inner end are the gears 20 and 22 while at the other end there is keyed a gear 24 and a suitable drive pulley 26 which serves to revolve the shaft and gears. A hollow shaft 28 is journaled in suitable bearings in the reciprocating frame 15 and at its inner end there is keyed the movable disk member 29 and adjacent thereto the gears 21 and 23 are loosely journaled on the hollow shaft and mesh with gears 20 and 22, respectively. Each of gears 21 and 23 has an extended hub portion, the former having the fan 30 keyed thereon and the latter the cam 31. At the other end of the hollow shaft 28 there is keyed a gear 25 which meshes with gear 24. Adjustment of pressure between the two disks is secured by means of a shaft 32 threaded into the hollow shaft 28 as indicated at 33. A hand wheel 34 serves as means to rotate the shaft and vary the pres sure between the disks, and a lock nut 35 to hold the parts in adjusted relationship. A thrust bearing 36 takes up the end thrust of the hollow shaft 28.
In operation, power is applied to the drive pulley 26 which rotates shaft 19 and the gears thereon. Gear 24 meshing with gear 25 drives the hollow shaft and rotates the rinding disk 29 in contact with disk 7. Flear 22 meshing with gear 23 rotates cam 31 between the guides 1414 which reciprocates the frame 15 and imparts lateral movement to the disk 29, and gear 20 meshing with gear 21 rotates the fan 30. The material to be ground is fed into the hopper 8 which guides it to the inner faces of'the disks where it is ground to the desired size which is determined by the pressure between the two disks. As the material is ground it drops down into the fan casing where it is picked up by the current of air from the fan and forced out through the opening 5.
Having thus described my invention, what I claim is 1. In a device of the character described, the combination with a support, of a member slidably mounted on said support, a shaft journaled in said member, a grinding disk mounted on said shaft, a second disk mounted in operative relationship to said first mentioned disk, a casing surrounding said disks, and means for rotating said shaft and reciprocating said member, thereby to effect a like motion between said disks.
2. In a device of the character described, the combination with a support, of a carriage cam and said support whereby rotation of 7 said shaft will reciprocate said carriage,and means for driving said shaft.
3. In a device of the class described, the combination with a support, of a carriage adapted to be reolprocated on said support, a
shaft journaled in said carriage, a grinding d1sk mounted on said shaft and rotatable therewith, a casing surrounding said disk, a
and disposed in operativerelationship to said rotary disk, and means for driving said shaft and reciprocating said carriage, thereby to effect a similar motion between said disks.
In testimony whereof, I hereunto aflix my signature.
MARCUS O. ANTHONY.
