UNITED STATES v PATENT OFFICE ROCK PULVERIZER Newton L. Matthews, Boise, Idaho Application October 4, 1938, Serial 110,233,269 3 Claims. (01. 83-9) This invention relates to rock pulverizers, and 22, the pinions or gears 22 of the revolving rod has for one of its objects, the production of a carriers meshing with a central gear 23 which simple and eflicient means for mounting and reis carried by the shaft l2. A suitable ore feeder volving the rod carriers within the casing of the 24 extends .centrally through the casing i3 and mill. extends around a shaft l2, as shown, for the pur- A further object of this invention is the propose of delivering the ore into the interior of the v duction of a simple and efilcient means for causcasing i3. ing the crushing rods tohave a bouncing motion Each carrier, 19, as stated above, comprisesa as the rod carriers are rotated.

Elon- Figure 1; I gated circular rods 32 are adapted to rest upon 20 Figure 4 is a sectional view taken on line |4 the resilient ring 31 in a manner as shown in of Figure 2; Figures 5 to 7, inclusive, and it should be under- Figure 5 is an enlarged side elevational view stood that these rubber or resilient rings'constiof one of the revolving rod carriers, certain parts tuting rubber tires will facilitate fast turning of being shown in section; the revolving rod carriers, give the same longer 25 Figure 6 is an end elevational view of one wear, and provide a bouncing motion for the of the revolving rod carriers, the supporting shaft rods 32 as they tumble from one position to anbeing shown in section; other through the rotation of the revolving rod Figure '7 is a transverse sectional view taken carriers. This bouncing motion will increase the on line 1-1 of Figure 5. pounding action of the rods upon the ore or rock so By referring to the drawings, it will be seen within the casing l3 and greatly reduce the wear that Ill designates the supporting standards and strain upon the frames l9. which are arranged in spaced relation, which As shown in Figure 4, a plurality of ore-lifting standards l0 carry journals in at their upper fins 33 are carried within the casing l3 and 'ex- 5 ends within which journals II is mounted the tend inwardly for a short distance toward the 35 supporting shaft l2. A casing i3 is carried center of the casing to provide ore lifters or oreby the shaft I 2 and comprises end plates l4 and lifting shelves to lift the ore upwardly within l5, which end plates carry the hexagonal sides the casing I3, as the same is revolved in the conl6 which hexagonal sides l6 support flat screen ventional manner.
40 plates H. The form of the casing [3, therefore, From the foregoing description, it will be seen 40 assumes a hexagonal shape which permits of the that a very simple and eflicient mill has been prouse of flat screens, in this way reducing the cost vided, the sides of which are so constructed as of construction as well as facilitating repair. A to provide a substantial hexagonal casing withrim or wheel I8 is carried by the end plate ll, as in which the ore or rock may be agitated as the shown in Figure 2, for the purpose of receiving casing is rotated. Furthermore, it will be noted 5 a driving medium such as a. belt B, or other suitthat I have provided rod carriers which revolve able driving means common to the trade. within the mill as the mill is turned and as the A plurality of revolving rod carriers I!) are gears 22 travel about the stationary gear 23. mounted within the casing I3 as shown, and The gears 22 and 23, because of their ratio, will these revolving rod carriers l9 are supported upon speed up the rod carriers so as to drive the same 50 journal shafts 20 and 2|, which shafts 20 and faster than the speed at which the exterior casing 2| are journaled within the respective end walls i3 of the mill may rotate. Furthermore, it will II and 15, as shown. Each carrier i9 comprises be noted that the rubber tires or rings 3| will a cylindrical frame, shown in detail in Figures provide a resilient abutment or buffer against 5, 6 and '7, the shaft 20 carrying a pinion or gear which the rods may strike when. crushing the 55 rock, in this way giving the rods a bouncing motion and increasing the pounding motion of the rods upon the rock or ore. Furthermore, it should be noted that the shape of the casing l3 will permit of the use of flat screens in place of the common type of curved screens which have previously been used, in this way reducing the cost of maintaining and construction thereof.
The shaft II, as well as the gear 23, may be mounted for support in a stationary manner within the journals H, the casing l3 being revolvable about the shaft l2 by causing the gears 22 to rotate for the purpose of rotating the revolving rod carriers at a greater speed than the speed of the casing l3, as above-stated.
Having described the invention, what I claim is:
1. A device of the class described comprising a support, a casing constituting a drum mounted for rotary movement upon the support, screens carried by the side walls of the casing, rotating carriers mounted within the casing and adapted to rotate on their own axes and also adapted to rotate about the axis of the drum, means for rotating the carriers, 8. driving wheel for the casing, a series of rods loosely supported within the carriers and adapted to have a tumbling action therein, and resilient bufl'ers carried by the carriersv adapted to be directly contacted by said rods.
2. A device of the class described comprising pat the junction of the side walls thereof and ex tending inwardly toward the center of the casing, said carriers being rotatable on their own axes within the casing, and said carriers being adapted to revolve about the axis of the drum.
3. A device of the class described comprising a support, a'casing constituting a drum mounted for rotatable movement upon the support, screens carried by the drum, rotating carriers mounted for individual rotation upon their own axes within the drum and adapted to revolve about the axis of the drum, elongated rods mounted within each carrier, resilient bands fixed within each carrier and adapted to directly contact with the rods, the rods being adapted to roll up the sides of the carriers upon the rotation of the carriers NEWTON L. MATTHEWS.
