UNETED MAX LINDEMANN, OF EAST ST. LOUIS, ILLINOIS, ASSIGNOR OF ONE-HALF TO EUGENE J. FEINER, OF ST. LOUIS, MISSOURI. v

CGEN-DEGERMINATOR.

Specification of Letters Patent.

Application filed May 17, 1815. Serial No. 28,60

To all whom it may concern:

Be it known that I, MAX LINDEMANN, a citizen of the United States, and resident of East St. Louis, Illinois, have invented certain new and useful Improvements in Corn- Degerminators, of which the following is a specification containing a full, clear, and ex act description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in corn degerminators, and the object of my invention is to construct a machine of this kind having two crushing elements, one arranged within the other and independently revoluble, the one only having provision for connecting with power while the other receives its motion from the first, when grain is fed between them, and is provided with a braking means for governing its speed, whereby both crushing elements may be rotated at variable speeds and the crushing accomplished without choking or overheating.

With the above purposes in view, my invention consists in certain novel features of the construction and arrangement of parts hereinafter fully set forth, pointed out in my claim and illustrated by the accompanying drawings, in which- Figure 1 is a longitudinal sectional elevation of a machine embodying my invention;

Fig. 2 is a transverse sectional elevation of the machine taken through the feed hopper; and

Fig. 3 is a view on an enlarged scale of the terminals of a band brake, showing the means for relatively hinging the band pieces and connecting them with the machine frame, and also the means for adjusting the free ends of the band.

Referring by numerals to the accompanying drawings:

5 designates the frame of the machine, which is provided with the journal bearings 6 in which bearings there is mounted a shaft 7.

On this shaft 7 there is a pulley 8 for connection with power for the driving of the shaft and keyed to the shaft there is a hollow conical body 9 whose exterior face constitutes one of the crushing surfaces of the machine.

Formed integrally with the conical body 9 at its reduced end there is a cylindrical extension 10 which constitutes a feed for the crushing surface of the conical body.

The end, of the cylindrical extension is closed by a disk 11 and this disk projects beyond the cylindrical extension and is surrounded by a hopper 12, spaced from the cylindrical extension, and supported by the frame 5 through the medium of the braces 13.

The numeral 14 designates a shell, preferably formed of mating halves, each half bearing perforated ears for connection by bolts or the like, and which shell conforms substantially with the conical body 9.

The reduced end of the shell is rotatably mounted in the hopper 12, while its other end is supported rotatably upon the shaft 7 At the larger open end of this shell there is a cylindrical extension 15, and surrounding this portion of the shell there is a band brake consisting of two metallic straps 16 and 17. At one end of each strap there is a bearing 18, and extended through these bearings there is a bolt 19 upon which the straps may hinge. This bolt is mounted on a bracket 20, which is fixedly secured to the machine frame 5. At the other end of each strap of the brake there is a flange 21, each of which is perforated to receive therethrough a threaded bolt 22. This bolt is extended through a bracket 23 fixedly secured to the machine frame opposite the bracket 20 and secured to the bolt is a hand wheel 24, whereby to relatively move the free ends of the straps forthe purpose of varying their frictional bearing upon the cylindrical extension 15 of the shell, in order to govern or control the speed of rotation of the shell. It is apparent from this showing that the machine of thisrapplication comprises two crushing surfaces whose speed of rotation may be relatively controlled, the one controlled directly by its connection with power and the other receiving its motion from the first or driven element, and its speed controlled by a brake.

Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent of the United States is:

In a machine of the class described, a frame, 'a shaft rotatably mounted on said frame, means for connecting said shaft with power, a crushing element supported by said shaft, means for causing said crushing element to rotate with said shaft, 0. second crushing element surrounding the first menable pressure upon the second mentioned tioned crushing element and loosely mountcrushing element.
