SEPARATOR.

Specification of Letters Patent. T Patented Dec. 24, 1912.

Application filed May 11, 1912. Serial No. 696,646.

Be it known that I, HENRY P. DE ZETTER, a citizen of the United States, residing at Byron, in the county of Genesee and State ,of New f York, have invented certain new .and useful Improvements in Separators, of

which the following is a specification.

' roun The object of this invention is to provide a machine for separating various kinds of grains but more especially for separating and grading beans. .That is separating the heavy, well formed beans from the light or poorly developed or mis-shaped beans and from' the small stones, dirt, etc., with'which they may be associated or mixed. The beans referred to are the white beans such as-are used for soup or baking which feed regulating device by which the feed of the beans to the separating mechanism is controlled.

These and other objects of my invention will be full illustrated in the drawings, de-

scribed in he'specification and pointed out in the claims-atthe end thereof.

In' the', accompanying drawings, Figure 1 lllustratesa front elevation of my improved separating machine as viewed from the right in Fig. 3. Fig. 2-is a side elevation of the duplexmachineconstructed according to my invention. -Fig. 3 is a sectional elevation of m'y 'inachine which sectionis taken on the line 3f-''3"" in Fig. 1. Fig. 4 is an enlarged detail sectional view of the feed regulating mechanism section being taken-on the line 4"4" of Fig. 1. Fig. 5 is a longitudinal section through the machine shown in Fig. 2.

In the accompanying-drawings, like reference characters refer to'like parts.

My improved separating machine consists of a framework 1 having the rollers 2, 3 mounted therein at the upper and lower ends thereof respectively. This framework is pivotally mounted at 5 on the legs 4 at the lower end and is also pivotally mounted on the adjustable support 6 at the upper end. This adjustable support has the threaded 'stem 7 thereon which passes through the bracket 8 and is supported thereon by the nut 9. By the turning. of the nut 9, the framework 1 can be swung around the pivot 5 and any angular adjustment of the framework can be secured.

Mounted in the framework 1 is the separating table 10 and bet-ween the rollers 2 and 3 passes the endless belt or apron 11, the movement of which is indicated by the arrows shown in Fig. 3. This table controls the'middle section which is sufiiciently parallel to the long sides of the framework 1, above which is the upper section which slants toward the horizontal and below which is the lower section which slants toward the vertical and the pitch of the slope being decreased in the upper section and being increased in the lower section differing in this respect from the pitch of the middle section.

Mounted on the framework 1 is the hopper 12 having the feed openings 13 in the bottom thereof, each of which feed openings is controlled by the feed regulator 14: which feed regulators are mounted on and rotate with the shaft 15, such as is shown in Fig. 1. Each of these feed regulators is composed of a pair of disks 16 between which is placed a'wheel having pocket-s or recesses 17 therein.- Fastened to the bottom of the hopper 12 are the guards 18 which'bear against the wheel of the feed regulator and prevent the beans or grain from working down back of the feed regulator and compel all of the materialto be separated-to ass over the feed regulator onto the separating apron 11.

As shown in Figs. 3 and 4, the material to be separated is placed in the'hopper 12 and that the sound heavy beans will roll down the intermediate portion of the table faster than the belt 11 is traveling upwardly thereon, so that such beans will rapidly approach the steeply inclined portion of the table at the end thereof. When the sound beans reach the lower portion of the table, they will roll faster due' to the increased steepness of the incline and pass ofi from the end thereof into the chute 20."- The light or misshaped beans will not roll down as fast as the belttravels up and will be carried above the middle portion of the table 10 onto the u per end thereof which is less steeply incllned, after which they will cease to roll at all and will be carried up over it practically as fast as the: belt travels. They will pass over the roller 2 and will be discharged into the chute 21 onto the table. By raising or lowering the upper end of the frame 1, the proper incline of the table 10 can be secured by which the separating machine will work with the most efiiciency and despatch.

In Figs. 2 and 5, I have shown views of the duplex machine. In this machine all of the beans are dumped into a single hopper 25 at the top, from which they are fed into the hoppers 26 and 27 and pass therefrom through the feed regulators 28 and 29 onto the belts 30 and 31 which traverse the separating tables 32 and 33. The heavy-beans are discharged into the spout 34 along which they are lined by the conveyer worm 3-5, while the light beans are discharged'into the chutes 36 and 37 at the opposite ends of the machine. The mac ine shown in Figs. 2 and 5 is mounted on t e base 38 on which are mounted the uprights 39, 40, 41 and 42, from which the various parts of the machine are supported. On these uprights are supported the upright frames 43 on which are mounted to run, a pairof cone pulleys 44 and 45. The pulley 44 is a driving pulley ried on the pulley 45 on the shaft thereof, are the pulleys for which belts run for driving the various parts of the machine. The belt 46 is used for driving the worm, the belt 47 for .driving the nearest feed regulating shaft from which in turn the farthest feed regulating shaft is driven by the cross-belt 48. The belt? 49 is also used for driving the nearest upper roller 2 and the cross belt 50 is used to convey the power therefrom to the opposite roller 2. ,By shifting the belt 51 laterally on the cone pulleys 44 and 45, any desired variation in the speed for operating the machine may be secured. I

In the operation of my machine, the beans are dumped into the hopper and pass through the feed regulator 14 which .deposits them in small streams upon the upwardly moving'belt. The heavy beans at once begin to roll down the belt faster than the belt travels up while the light beans roll down more slowly than the belt travels up or do not roll down at all. Thus the heavy beans soon reach the steep, inclined portion of the table at the bottom thereof, while the light beans soon reach the upper portion of the table which is almost horizontal. The separation is thus quickly effected and the highgrade beans are deposited into the lower chute while the low grade beans are carried into the upper chute.

Having thus described my invention, what I claim as new and patentable is as follows:

1. In a separating machine, the combination of an inclined table, a belt traveling up over the said inclined table, said inclined table having three grades of inclination thereon arranged progressively from top to bottom, the lightest inclination being at the top and the heaviest inclination at the bottom.

2. In a separating machine, the combination of a frame, a table secured therein, a belt mounted to travel over said table, said table having three grades of inclination therein, the middle part of said table having a moderate inclination, the upper part of said table having a light inclination and the lower part of said table having a heavy inlclination.

3. In a separating machine, the combination of a frame, a table secured therein, a beltmounted to travel over said table, said table having three grades of inclination therein, the middle part of said table having a moderate inclination, the ,upper part of :said table having a light inclination and the lower part of said tablehaving a heavy inclination, rollers at each end of said table,

.said belt traveling over said rollers and said table, a chute adjacent to each of said ;rollers.

and the pulley 45 is a driven pulley. Car- 4. In a separating machine, the combinasively from top to bottom, the lightest inclination being at the top and the heaviest inclination at the bottom, said belt moving continuously in one direction and being adapted to receive unsorted grain thereon and to separate it by the movement of the belt and inclination of'the table and dis- ;charge the sorted material at the opposite fends thereof.

5. In aseparating machine, the combination of an inclinedv table, an endless im-' pervious belt traveling up over said inclined table, said table having two grades of inclination thereon arranged progressively from top to bottom, the lighest in-' clination being at the top and the Heaviest inclination at the bottom, said belt moving In testimon whereof I aflixmy signature continuously in onedirection and being in presence 0 two witnesses.

adapted to receive unsorted grainflthereon and to separate it into rades by the movement of the belt and inc ination of the table, and discharge the different grades at the opposite ends thereof.
