RICHARD M. HOLLAND, OF ELKTON, SOUTH DAKOTA.

SMUT-MACHINE Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed May 27, 1907. Serial No. 375,987.

To all whom it may concern:

Be it known that l, RICHARD M. HOLLAND, i

a citizen of the United States, residing at Elkton, in the county of Brookings and State of South Dakota, have invented a new and useful Smut-Machine, of which the following is a specification.

This invention relates to improvements in means for separating smut from grain, though adapted for other analogous purposes.

The principal object of the present invention is to provide novel, simple and effective mechanism, which will unquestionably per form the separating operations, and will eliminate the moisture from the grain separated.

A further and important object is to provide separating mechanism that can be adjusted to operate upon grain of difierent grades and characters and under different conditions.

The preferred form of construction is illustrated in the accompanying drawings, where- 111 Figure 1 is a plan view of the machine. Fig. 2 is a longitudinal sectional view therethrough. Fig. 3 is a vertical cross sectional view. Fig. 4 is a detail side elevation. Fig. 5 is a cross sectional view through the shaking screen. Fig. 6 is a cross sectional view through the grain conveyer. Fig. 7 is a detail perspective view of one of the blades of the skimmer conveyer.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, a suitable reservoir 8 is employed mounted on standards 9 that are located at the ends of said reservoir. Driving shafts 10 and 11 are journaled in the upper ends of the standards, and are suitably connected by gearing 12, preferably a sprocket belt and wheels. A frame 13 is pivotally mounted at its upper end upon the shaft 10, and extends downwardly into the reservoir. The lower end of this frame has cables 14 connected thereto, said cables being wound upon a drum 15. The drum is in the form of a shaft that extends transversely of the reservoir, and has a suitable handle crank 16 at one end. A dog 17, co operating with a ratchet wheel 18 fixed to the shaft or drum, normally holds it against rotation in one direction. A shaft 19 is journaled on the lower end of the frame 13, and

an endless conveyer passes around the shafts 10 and 19. This conveyer consists of spaced sprocket chains 20 that pass around sprocket wheels 21 fixed to the shafts. Bridge-pieces 22, one of which is shown in Fig. 6, connect the chains, and secured to these bridge-pieces is an endless trough that comprises a series of plates 23 having outstanding end flanges 24 and having their opposite side margins hinged together, as shown at 25. The result is, as shown in Figs. 1 and 2, a flexible continuous trough having a continuous ribbed upper stretch.

Another frame 26 is pivoted to the shaft 11 and extends downwardly into the reservoir, its lower end being located over the above described conveyer. The lower end of this frame is connected by links 27 with the frame 13, so that upon the adjustment of the lower frame, the upper frame will be adjusted with it. A shaft 28 is journaled in the lower end of the frame 26, and the shafts 11 and 28 are provided with sprocket wheels 29 around which pass spaced sprocket chains 30. These chains are connected by plates 31, on which are hinged blades 32 yieldingly maintained in outstanding relation by springs 33. A plate 34 is located below the frame 26 and conveyor and is hinged at its upper end, as shown at 35. The lower end of this plate is connected by plates 36 to the frame 26.

A hopper 37 is supported upon the reservoir, and has its lower discharge end 38 located above the conveyer trough and preferably at one side of the lower end of the con veyers -32. Beneath the upper end of the longer conveyer is arranged a shaking screen 39 that is ribbed, as shown, and is mounted in a frame 40. The outer end of the frame has depending links 41 mounted upon the cranks 42 of an adjusting shaft 43. The inner end of the frame is supported by links 44 and is connected by pitmen 44 to the cranks of a shaft 45, and this crank shaft is geared, as shown at 46 to the shaft 10. A return board 47 is located beneath. the screen and inclines downwardly toward the reservoir. Beneath the outer end of the other conveyer is located a perforate draining board 48, and a downwardly inclined return board 49 is disposed beneath the same. In operating the machine, the reservoir is 1 filled with water, and power is applied to the shaft 10. The grain to be separated, is then will gravitate placed in the hopper 37 and The heavier downwardly into t e reservoir.

grain will drop u on the endless trough or conveyer, and wil be elevated thereby from the water on to the shaking screen. Here the adhering moisture will be removed, and passing through the screen, will return into the reservoir, the grain passing from the outer side of the screen. The smut, false or worthless grain and like trash which floats upon the surface is caught by the springpressed blades 32 and elevated from the reservoir, being thrown upon the draining board 38; The water passes through the board and is returned to the reservoir. It will be evident that the depth of the conveyers can be readily changed by raising and lowering the frames, and thus grain of different character can be properly operated upon. Moreover, the inclination of the shaking screen can be altered by operating the rock shaft 43 so that the grain can be retained upon the said screen for different lengths of time in order that the water may be properly eliminated.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape,

proportion, and minor details of construc tion, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
