EDWARD H. GEISE, OF NEWTON, IOWA.
SEED-SEPARATING MACHINE.
To all whom it may concern:
Be it known that I, EDWARD H. GEIsE,
a citizen of the United States of America, and resident of Newton, Jasper county, Iowa, have invented a new and useful Seed-Separating Machine, of which the following is a specification. The object of this invention is to provide improved means for cleaning seed and grain, and for separating one kind of grain from another.
A specific object of this invention is to provide improved means for cleaning wheat, whereby all oats are removed from the wheat in addition to cleaning the same.
My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which Figure 1 is a side elevation of the complete machine. Fig. 2 is an opposite side elevation of the complete machine. Fig. 3 is a plan of a battery of screens or sieves removed from the machine. Fig. 4c is a longitudinal section on the indicated line 4-4: of Fig. Fig. 5 is a detail plan of the uppermost screen of the battery illustrated in Fig. 3, the apron being rolled back to uncover the face of the screen. Fig. 6 is a detail plan of the lowermost screen of the battery illustrated in Fig. 3. Fig. 7 is a detail section of one of the shoes.
In the construction of the machine as shown the numeral 10 designates a base. Standards 11, 12 and braces 13 are arranged in pairs and rise from the base 10. The braces 13 are attached to the upper end portions of the standards 12. A hopper lt is mounted between and fixed to the upper end portions of the standards 11 and braces 13, and a gate 15 of conventional form, shown by dotted lines in Fig. 1, is mounted slidingly in and adapted to close the bottom of said hopper, and said gate is arranged for reciprocation manually by means of a screw 15 A shoe 16 is mounted between the standards and braces and is suspended at one end flexibly on hangers 17 fixed to the upper end portions of the standards 11. The end portion of the shoe 16 suspended by the hanger 17 is located beneath the opening in the bottom of the hopper 1A. The shoe 16 is inclined downwardly from its point of support on the standards 11, and
the opposite end portion thereof is carried Specification 01 Letters Patent.

by a rod 18 extending transversely of said shoe and having its ends pivoted in levers 19, 20. The levers 19, 20 are arranged vertically and are fulcrumed intermediate of their ends on brackets 21, 22 fixed to the standards 12.
A shoe 23 is mounted between the standards and braces and is inclined. The upper end portion of the shoe 23 is open and connects with an opening in the lower end portion of the shoe 16. The upper end portion of the shoe 23 is carried by a rod 21 extending transversely thereof and having its ends pivoted in the levers 19, 20 beneath the brackets 21, The lower end portion of the shoe 23 is supported by hangers 25, 26 (shown by dotted lines in Figs. 1 and 2) flexibly connected to the standards 11. The lower end portion of the shoe is open, and discharges longitudinally of the machine. A blast-fan 2: is mounted on the braces 13 and is driven by a shaft 28 journaled on said braces. Pitman 29, 3O connect wristpins 31, 32 on the shaft 28 to the lower ends of the levers 19, 20. A sprocket wheel 33 on one end portion of the shaft 28 carries the wrist-pin 31 and is connected by a chain 34: to a sprocket wheel 35 mounted on, a stub axle 36 journaled in the upper end portions of one brace 13 and one standard 12. A winch or hand-crank 37 is lined to and GX- tends radially of the sprocket wheel 35 and is adapted for manual operation to rotate said wheel. It will be observed that the sprocket wheel 33 is of materially less diameter than the wheel 35, thus providing for greatly increased speed of the shaft 28 and fan 27 relative to the speed of the handwheel. The fan 27 discharges into the upper end portion of the shoe 23 and is adapted to force a blast of air across the path of travel. of grain or seed through said shoe, said blast of air being discharged through an opening 38 laterally of the shoe and carrying with it the chafi' and light seed not otherwise discharged.
A battery of screens is mounted in the shoe 16 and is held in desired position therein by clamping the sides of the through the medium of a bolt 39 extending transversely of the shoe, headed on one end and provided with a nut 40 on the other end. The battery of screens is constructed as follows: The base screen comprises sidepieces 11, 42, end-bars 43, 4 1 connecting said side-pieces, and a screen bottom or sieve.
shoe together The screen bottom or sieve is constructed preferably of a single sheet of metal perforated, pierced or apertured on alternate sections or portions thereof, the perforated portions 45 alternating with imperforate portions 46, as illustrated in Figs. 4 and 6. The side-pieces 41, 42 are beveled on their inner faces and serve to guide and direct grain longitudinally of the screen. A cleat 47 is mounted transversely of the screen and fixed at its ends in notches in the upper margins of the side-pieces 41, 42, and said cleat is spaced apart from the screen bottom or sieve. An apron 48 is fixed to one margin of the cleat 47 and depends therefrom, and extends over a perforated section or strip 45 of the screen bottom. The apron 48 preferably is made of oiled cloth or similar fabric having a smooth surface adjacent the screen bottom or sieve. A secondary screen indicated generally by the numeral 49, of a construction identical with the lowermost screen, is superposed on said lowermost screen and extends at one end beyond one end thereof, in such manner that the imperforate portions-46 of the secondary screen overlie and are spaced apart from the perforated portions 45 of the lowermost screen. A cleat 47 on the secondary screen carries an apron 48 overlying a perforated section 45 of said secondary screen, and said apron is of the same construction as the apron 48. A third screen, indicated generally by the numeral 50, is superposed on the secondary screen and extends at one end over one end of said screen in such manner that imperforate section 46 of the third screen overlie and are spaced apart from perforated sections 45 of the secondary screen. A cleat 47 011 the third screen carries an apron 48 overlying a perforated section 45 of its bottom, and said apron is of the same construction as the other aprons described. An upper screen indicated generally by the numeral 51 is superposed on the third screen 50 and extends beyond one end of said screen.
Cleats 52, and 54 are mounted on and transversely of the screen frame 51 below the bottom of said screen, and said cleats carry aprons 55, 56 and 57 depending therefrom and overlying perforated sections 45 of the third screen. The bottom 58 of the screen 51 is perforated throughout uniformly. 1L cleat 59 is mounted on and transversely of the initial end portion of the screen frame 51, and an apron 60 of the same construction as the other aprons described depends from said cleat and overlies the entire perforated bottom. The uppermost screen 51 is shown in detail in Fig. 5 with the apron 6O rolled back to expose the screen bottom 58. It is to be understood that any desired form of screen bottom is to be employed, dependent on the kind and quality of grain or seed to be separated, but I have illustrated the form of screen having round holes and perforated in alternate strips as shown, since such form is especially applicable to the separation of oats from wheat.
In practical use, the grain or seed to be cleaned is deposited in the hopper 14 and discharged through the bottom of said hopper upon the uppermost end of the uppermost screen 51 in such manner that all the grain or seed flows below the cleat 59 and apron 60 and traverses the length of the bottom 58. It will be understood that the battery of screens is vibrated longitudinally through vibration of the shoe 16, by the levers 19, 20, and hand mechanism acting on said levers and vibrating the rod 18, and that such vibration causes the grain to travel longitudinally of the screen bottoms. The apron 60 holds the long grain or seed, such as oats, flat to the bottom 58, so it will pass over the round holes, and impedes or retards the progress of all seed along said bottom, thus insuring the passage through the apertures of said bottom of all of the grain, seed, such as wheat, chaff, and such material smaller than the oats, and said cats are discharged from the lowermost end of the uppermost screen upon the apron 48 and are further discharged from said apron to the apron 48 and the apron 48 to the inclined closed end of the shoe 23, and thence upon the fan chamber and into the receptacle 61 provided therefor. The seed and other substance that passes through the perforated bottom 58 of the uppermost screen is received on an imperforate portion of the bottom of the screen 50 and on the aprons 55, 56 and 57, and by them discharged to said bottom. All of the smaller portions of seed pass through the perforated portions 45 of the bottom of the screen 50, and the larger portions, such as oats, travel along said bottom beneath the aprons and discharge upon the apron 48 and are conveyed thence over the same course as above described to the receptacle 61. The substance that passes through the bottom of the screen 50 is received on an imperforate portion of the bottom of the screen 49 and the finer particles thereof discharge through the perforated portions 45 of said bottom, while the larger substance travels along said screen and beneath the apron 48 and discharges on the apron 48, from whence it is conveyed in the manner above described to the receptacle 61. The substance that passes through the perforated portions 45 of the bottom of the screen 49 is received on an imperforate portion of the bottom of the screen 44 and the finer particles thereof discharge through the perforated portions 45 to the bottom of the shoe 16, while the coarser portions travel along said screen bottom beneath the apron 48 and are conveyed to the receptacle 61 in the manner above described. The finer substance travels along the bottom of the shoe 16 over a screen 62 at the lower end portion of said shoe, and part of such substance discharges through said screen into a spout 63 and is conveyed laterally of the shoe. A gate 64 is slidingly mounted transversely of the shoe, and may be employed to cut off the discharge through the screen 62 to the spout 63. The remaining substance discharges from the open end of the shoe 16 into the upper end of the shoe 23 and is directed by inclined partitions across the blast of air from the fan 27 in a conventional manner. The blast of air from the fan 27 forces the chaff and very light particles out of the substance treated through the discharge port 38, and the remainder of the substance travels along the bottom of the shoe 23. The bottom of the shoe 28 is a screen 65 adapted to separate very fine particles from the remainder of the substance, and the fine particles are discharged within the base 10, while the purified and cleaned seed, such as wheat, is discharged at the point 66 on the floor or in a receptacle provided therefor. The battery of screens can be adjusted to any desired inclination by loosening and tightening the bolt 39 and nut 40. Any desired change may be made in the battery of screens, such as by supplying additional screens or using different sizes, or by removing one or more of them to suit varying kinds of work.
I claim as my invention- 1..In a seed-separating machine, a shoe adapted to be suspended in inclined position and arranged for oscillation, a battery of screens mounted in said shoe and composed of screen frames and bottoms thereon, the first bottom being perforated throughout, an apron overlying all the perforations of the first bottom, the remaining screen bottoms formed of alternate perforated and imperforate strips, said frames arranged relative to each other so that the perforated strip of one bottom is overlaid by an imperforate strip of another bottom, aprons carried by the second frame and wholly overlying perforated strips and overlapping imperforate strips in the second bottom, and aprons carriedby successive frames and wholly over1y-' ing terminal perforated strips and overlapping terminal imperforate strips of the bottoms in combination with a screen transversely of the lower end of the bottom of said shoe, a spout carried by said shoe beneath the screen, and a gate between said spout and screen and in the same plane as the bottom of the shoe.
