UNITED STATES PATENT EEicE.

LOS ANGELES, CALIFORNIA, ASSIGNOR TO CHARLES H. FROST, OF SAME PLACE.

CLAY-REDUCER.

SPECIFICATION forming part of Letters Patent No. 412,321, dated October 8, 1889.

Application filed April 5, 1889. Serial No. 306,111. (No model.)

To all whom, it may concern.-

Be it known that I, IVALFRID BURKMAN, re siding at Los Angeles, in the county of Los Angeles and State of California, and acitizen of the United States, have invented a new and useful Improvement in Clay Reducers and Disintegrators, of which the following is a specification, reference being had to the accompanying drawing, in which there is a single figure, which is a vertical longitudinal section.

My present invention is an improvement on a machine for which Letters Patent of the United States No. 312,808 were granted on my application.

The leading objects of my invention are to improve the construction an d arrangement of the working or reducing parts of the machine, and to provide improved means for feeding the clay thereto, all of which I accomplish as illustrated in the drawing and hereinafter described. V

That which I claim as new will be pointed out in the claims.

In the drawing, A represents aframe, which is supported on masonry or in any other suitable manner. This frame carries a hollow shaft B, mounted in the bearings (J, and it is driven by a band-wheel D. This shaft B extends beyond one of its bearings, and on that end there is secured a disk E.

F is another disk, which is connected with Two only of these bars G are shown in the drawing; but I use four or more. The disk F is provided with several rows of pins to, concentrically arranged, and has a large central feed-inlet 6.

His a shaft,which passes through the hollow shaft B. This shaft H is supported in suitable bearings at its ends, only one of which 0 is shown. The bearing for the other end of this shaft H is similar to the one shown (2.

I is a rotating disk secured to the shaft H and located between the two disks E and F. This disk-I is provided with rows of concentrically-arranged pins d, arranged to pass be tween the pins a on the disk F.

The shaft H extends through the hollow shaft B and carries at one end a band-wheel J and a fly-wheel K.

L is a feed-spout, through which the shaft I-I passes.

M is a case over the rotating disks.

The shaft B is babbitted throughout its en- '5 tire length, and the shaft H revolves in it. The shafts B and H are rotated in opposite directions, (indicated by arrows,) and in use I run the inside shaft H about double the speed of the hollow shaft B.

In my former machine, above referred to, the clay was fed by means of a horizontal screw which passes through a hollow shaft. By connecting the rotating disk F with the rotating disk E the disk F is supported by and carried around with the disk E, and this construction enables me to provide a large feed-opening b in the disk F, through which opening the feed-spout L passes.

In use the clay which is to be reduced is fed to the machine through the feed-spout L, and it will fall by gravity directly into the machine and come in contact at once with the rotating pins, and all danger of clogging will be avoided. The clay will be reduced by the actions of the pins a and d, substantially as in my former machine, the reduced clay falling to a place provided for it beneath the rotating reducer.

The two disks E and I are arranged rela- 8o tive to each other, so that there is a little space between them. The pins a on the disk F are of such length that their free ends are very near to the disk I, and the pins d on the disk I are of suchlength that their free ends 8 5 are very'near t0 the disk F. Thus only a very narrow channel is left between the free ends of the pins and the disks, and thereby the entire space between these two disks is practically occupied by the pins.

\Vhat I claim as new, and desire to secure by Letters Patent, is as follows:

1. In a reducer and disintegrator, the combination of a rotating disk E on a shaft and a disk F, connected with and supported by 5 the disk E and carrying rows of pins a, and

the disk F, having a central feed-opening- 1), opening I), a disk I, provided with pins d, substantially as and for the purposes speeiand a shaft H, which carries the disk I, subfied. stantiaily as and for the purposes specified. '10

2. In a reducer and disintegrator, the con 1- VVALFRID BURKMAN. 5 bination of a disk E, mounted on a hollow WVitnesses:
