Application filed June 19, 1918.

which the following is a specification, reference' being had to the accompanying drawings.

This invention relates to an improved reducing mill, and has for its primary object to provide a mill which is particularly designed for reducing or macerating products to be usedas stock feed, which consists of relatively few parts and may be manufactured and sold to the stock raiser at nominal cost.

, It is another object of my invention to provide a reducing mill embodying a rotary cutter, and ,means for initially breaking up the feed and evenly distributing the same longitudinally over and upon the rotary cutv ter.

And it is another important object of the invention to provide a device for the above purpose which will occupy relatively small space and be of maximum capacitv. the mill being operable either manually or by means of a motor or other suitable power.

With the above and other objects in view, the invention consists in the improved construction, combination and relative arrangement'of the several parts as will be hereinafter more fully described, subsequently claimed and illustrated in the drawings in which similar reference characters designate corresponding parts throughout the several views, and wherein:

and the cost to the farmer or stock raiser of having the beans milled or reduced to suitable condition for stock feed is $4: to $5 per ton. It is, therefore, the primary object of the present invention to provide a reducing or macerating mill, by means of which the individual farmer at relatively small cost can reduce the beans into the desired comminuted condition and render the same available for stock feeding purposes.

With the above end in view, I have devised my improved reducing mill which in the illustrated embodiment thereof includes spaced bearing supports 5 of suitable construction, which may be bolted or otherwise anchored to a platform or base. Between these supports, a cylindrical cutter 6 is disposed, said cutter having spaced spirally arranged continuous cutting teeth 7 formed upon its periphery. The cutter shaft 8 is journaled at its opposite ends upon the bearing supports 5, and a housing 9 fixed upon said supports extends over the cylindrical cutter. This housing is centrally formed with a cylindrical shell 10 opening at its lower side into the housing immediately above the spiral cutter 6. One side wall 9 of the housing 9 is disposed in close contiguous relation to the spiral blades or teeth 7 of the cutter, while the opposite side wall 9 of the housing is curved on a relatively wide arc and has its inner'face spaced an appreciable distance from the periphery of the cutter. To the bearing-supports 5-, and below the side wall 9 of the housing, the supporting and guide plates 11 are fixed. Upon these plates, the transversely adjustable member 12 is arranged, said member extending in parallel relation to the axis of the cylindrical cutter 6. The inner face of this member 12 is concaved as at 13 in eccentric relation to the cutter 6, said member having an inner longitudinally extending knife edge, shown at 14, disposed in a plane in tangential relation to the lower side of the cutting cylinder. The concave face 13 adjacent to said knife edge is grooved or corrugated, as shown at 15, for a purpose which will be presently explained.

A longitudinally extending bar 16 is fixed at its ends to the bearing supports 5. An adjusting screw or bolt 17 is centrally mounted in this bar and has threaded engagement in the member 12. Nuts 18 and 19 are threaded upon the bolt and are adapted to i the trough 21, oneend of said wormbeing be engagedagainst the opposite sides of the bearing 16 to retain the member 12 in its adjusted position relative to the: cylindrical cutter 6.

Upon one end of the shell 10, the flange 20 is formed, and to this flange the feeding Y trough 21 issecurelv bolted atone of 113$:

ends. The upper portion of one side wall of said trough is obliquely inclined in" an outward direction. as at-22, while the opposite side wall of the troughextends upwardly in a wide curve or arc, as shown at'2 3.. 24: designates the feed hopper, which is suitably mounted and secured uponthe walls of the trough 21. j r

A feed worm25 is rotatably mounted in journaled' in the outer end wall of the trough wall of the trough 21 on the opposite side ofits longitudinal axis with respect to the Wall23. of said trough, a longitudinally ex 7 tending groove or channel29 is formed, As

' the beans are fed by gravity from' the hop' per 24' into the trough, they move down-j wardlybetween the toothed worm and the I wall23 and are carried bythe worm teeth downwardly into the trough and into the groove or channel 29. Thus, in the rotation o-f'the worm,the beans will bebroken upinto coarse particles." Thebroken beans ,are'

then conveyed by the worm into the shell 10 and evenly distributed over andupon the revolving cylindrical cutter ,6. This cutter carries the material downwardly through the space between the cutter and the housing wall' 9 and delivers'the same upon theconcave face' 13 of the member 12, over which j it gravitates downwardly upon the corrugations 15. These corrugations serve to check the flow of the material and counteract the tendency of'the draft "around the cutter 6 and'between the same and'the member 12- r I cutter, saidteeth act to shave or shred the to draw and packthe material-between the concave face 13 and 'the cutterand "thus choke'up. the machine so that the cutter would not operate to effectively cut or shred.

In the illustratedembodiment of invention, I have disclosed'means for manually operating the'mill. To this end,an arm ,or bracket 30 is formed upon one end of the housing 9 and upon a stud bolt or shaft 31 invention as claimed. f

It will thus 7 be seen that 'when the gear wheel 32 is turned by means of the crank, rotation isimparted to, the feed worm and. the cutting cylinder in relatively opposite directions.
