To all whom it may concern:

Beit known that I, ALVAB: D. HADSEL, a citizen of theUnit/ed States, and a resident of San Francisco, county of San Francisco,

corrugated concave whereby the rock is I broken up.

The preferred forms of my rock crusher are shown in the accompanyingdrawings in which Figure 1 represents a vertical section through my rock crusher taken along line 1-1 of Figure 2, Figure 2 a horizontal I cross section taken along line 2-2 of Figure 1, Figure 3 a horizontal cross section through a modified form taken. along line 3-3 of Figure 4 and 'Fi 4 a vertical section through said modi ed form. While I have shown only the preferred form of the invention it should be understood that various changes or modifications may be made within the scope of the claims hereto at- 80 tached without departing from the spirit of the invention.

Referring to the forms illustrated in Figures 1 and 2 it will be seen that my rock crusher rests on a frame (1) made inc-any 85 suitable" manner which supports the receptacle .(2), conical in its lower portion and c lindrical in its enlarged upper portion. 5} rough the frame extends a vertical shaft (3) resting on the thrust bearing (4), the lower race (6) of which is sup rted on the hub (T) of a spider (8) provi ed in the oil reservoir (9). A s cond bearing (11) serves to support the upper end of the shaft. A rotor (12) is keyed to the uppe the shaft. It may be of any suitable construction and is shown in the drawing as comprising abottom plate (13) a top plate 7 (14)]and two channel irons (16) connectin ,the' same so as to form a sli htly curv I remforcin the. upper member. The n per plate (14 is rovided with a central opening (18) wit which communicates the spout (19) of a hopper ('21). In the upper enlarged porthe corrugated r end of tion of the receptacle (2) I provide a corrugated concave (22), the corrugations preferably formed in such a manner that rocks discharged from the rotor strike the con' cave substantially at right angles. The shaft may be rotated in any suitable manner as for instance by means of a. belt (23) engaging a pulley (24) secured to the shaft.

The operation of this device should be readily understood from the foregoing description. Rock is fed into the hopper by any suitable means and delivered by the same to the rotor (12) centrifugal power at the periphery of the rotor and thrown violently against the corrugated concave (22). After striking the concave and being crushed thereby the rocks drop through-the conical receptacle (2) on the inclined plate (26) which delivers them to any suitable receptacle through the outlet 27 T he modified forms shown in Figures 3 and 4 work substantially on the same principle but involve a somewhat diifere-nt arrangement. In this modification the vertical shaft (31) supporting the rotor (32) and supported in the thrush bearing (33) provided in the frame (34) is driven by means of an electric motor (36) provided on top of the frame (34). Pillars (37) form the base for the frame (34) and for the concave (38) and the rock is delivered into the central portion of the rotor through the pipe (39) and drops after having struck concave into the conical receptacle (41). This modification is slightly inferior to the forms shown in Figures 1 and 2 in so far as the shaft (31) extends into the rotor and into the intake passage (39) which interferes to some extent with the motion of the rock. It presents an advantage however, in the direct drive for the shaft.

I claim:

1. In a centrifugal rock crusher, a rotor adapted'for receiving the rocks centrally and discharging them peripherally, said rotor comprising a securing to a shaft, a centrall perforated disk axiallyaligned with the liubb'ed disk,

and a pair of similar spacing members between the disks extending entirely across the disks spaced from the central portion thereof and secured to both disks.

It is discharged by hubbed disk adapted for 2. In a centrifugal rock crusher, a rotor between the disks extending across the disks adapted for receiving the rocks centrally spaced from the central portion thereof and and discharging them peripherally, said secured to both, said spacing members being 1 rotor comprising a hubbed disk adapted for oppositely curved along their working faces 5 securing to 'a shaft, a, centrally perforated substantially as shown.

disk axially aligned with the hubbed disk, and a pair only of similar spacing members ALVAH D. HADSEL.
