MALT-BRUSHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 417,631, dated December 1'7, 1889.

Application filed March 7, 1889.

To all whom it may concern.-

Be it known that I, JOHN M. CASE, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Malt-Brushing Machines, of which the following'is a full, clear, and exact specification, reference being had to the accompanying drawings, in whichc Figure I is a side elevation of my machine, and Fig. II is a longitudinal section of the same. v

This machine has for its object to aiford simple, compact, and efficient means whereby the roots or germs maybe removed from malt or from the barley after it has been germi nated or rotted and dried.

To this end the machine consists in mounting in a suitable frame a hopper, a feed-box beneath said hopper, a concave perforated cloth into which said feed-box delivers, a rotary brush-cylinder mounted above said concave cloth in such close proximity thereto as to act upon a layer of material collected therein, a suitable spout leading from the edge of said cloth opposite to the feed-box, and a vertical suction chamber or spout, with the upper end of which communicates an airtrunk and the lower end of which communicates a conveyer-trough, a suction-fan being also connected with the air-trunk, and suitable air-inlets being formed at the desired points in the vertical suction-spout.

My machine further consists in certain details of construction of the above-named principal parts, all of which will be more fully hereinafter described, and particularly pointed out in the claim.

In the above-mentioned drawings, 1 represents the hopper, carried by and communicating with a feed-box 2. In this feed-box is located beneath the mouth of the hopper a sh elf 3, which catches the material and allows it to gradually flow over a low vertical side 29. This feed-box is further provided with an inclined bottom 7, extending through an opening 8 into the brush-chamber 12 of the machine. The outlet of the feed-box is over this inclined bottom.

11 represents the axis of the rotary brush- Serial No; 302,252. (No model.)

cylinder 15,having suitable brushes 16, which brushes are preferably made of rice-root or other coarse material. The shaft 11 also carries at one end the eccentric 10 and connecting-rod 9, the other end of which is bolted or otherwise secured to the side of the feed-box 2. The feed-box 2 is hung by means of rods 4, pivotally connected at 5 to the frame 30, and similarly connected by means of wristpins 6 to said box. From this construction it will be observed that upon rotation of the cylindrical brush a reciprocating motion will be imparted to the feed-box 2, which will cause the material to be treated to gradually flow in a thin stream from the shelf 3 over the incline 7 and into the chamber 12.

14 is the concave cloth, secured in any preferred manner in the brush-chamber. This concave cloth is perforated, and preferably constructed of rolled wire, the mesh being of such size as to permit the passage of a large proportion of the roots or germs, which are collected by a hopper and conveyor 13 below, but not to permit the passage of coarse material.

17 represents the outlet from the concave cloth to the suction-spout, which is formed by the angle-boards 18 19, so constructed as to allow the material to freelypass off at the bottom and catch any material which may be thrown too far upward by the bruslrcylinder at the top and then guide the material downward as it enters the suction-spout 20.

21 22 are inlets in this suction-spout, which may be locatedat any desired points beneath the opening 17.

23 is an air-passage communicating between the air-trunk 2 1 and suction-spout 20. The air-trunk 2i is provided with a regulatorvalve or damper 2 7, and communicates through eye 25 with the fan 26. The fan 26 has the outlet 28, which may communicate, if desired, with any suitable dust-collector or other mechanism in which it may be desired to collect and treat the roots or germs of the barley.

I have only shown a longitudinal section of my machine, inasmuch as the parts are all clearly shown thereby, and I desire it understood that the feed-box, concave cloth, rotary of the machine.

brush, suction-spout, air-passage 23, and airt-runk all extend to nearly the whole length The fan 26 has a suitable driving-shaft, and the whole machine is supported by a suitable frame 30, constructed in any desirable and convenient form.

This machine is intended to be constructed so as to occupy small space, but to treat the material very eitectively. The material is fed in a broad but thin stream onto the concave cloth, where it is thoroughly brushed and scraped to remove allthe roots, some of which pass down into the hopper, the remainder passing off with the coarse material and being delivered in a very thin stream into the suction-spout, where the upward current is strong enough to completely remove all the remaining roots or germs and carry them over into the fan. The suction-fan, as before stated, is

connected to some suitable dust-room or dustcatcher, or it may be a dust-catching fan so arranged as to both produce the suction and catch the dust.

If desired, means may be provided whereby the cloth and brush may be brought closer together or farther apart, so as to regulate the action of the brush upon the material. This could be done by raising or lowering one end of the cloth or by raising or lowering the jour-' nals of the cylinder.

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

In a machine for removing the germs from malt, the combination of an oscillating longitudinal feed-box having a broad deliveryspout 7, a stationary perforated concave cloth, onto which the feed-box empties, a rotary brushing-cylinder above the cloth acting upon the material, a longitudinal angular guidespout or passage 17, for catching the material when thrown up by the brush and directing it downward, and a narrow vertical suctionspout, into which the spout 17 empties, having a suitable fan, and the openings for inletof air just below the spout 17, all substantially in the manner and for the purposes explained.
