GRAlN-SEPARATOR MACHINE.

SPECIFICATION forming part of Letters Patent No. 515,542, dated February 2'7, 1894.

Application filed May 11, 1893. Serial H0473 ,772. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM H. WEBB, a citizen of the United States, residing at Longmont, in the county of Boulder and State of Colorado, have invented a new and useful Grain-SeparatorMachine, of which the following is a specification.

This invention relates to grain separator machines; and it has for its object to provide an improved machine of this character, which, while particularly adapted for the separation of green from ripe peas for'the convenience of canning factories, at the same time is also adapted for use as a grain separator for the separation of oats and barley and weed seeds from wheat, and other separations which will be hereinafter referred to.

To this end the main and primary object of the present invention is to provide an improved separator machine which dispenses with the ordinary sieve and air currents and relies particularly upon the natural specific gravity of the elements to be separated from each other.

With these and other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of partshereinafter more fully described, illustrated and claimed.

In the accompanying drawings :Figure l is a side elevation of a separator constructed in accordance with this invention. Fig. 2 is a central vertical longitudinal sectional view of the same. Fig. 3 is a detail sectional view on the line m-ac of Fig. 1. Fig. 4 is an enlarged detail sectional view of a portion of one of the drag aprons. Fig. 5 is a detail sectional view showing the attachment of one of the perforated elevator slats.

Referring to the accompanying drawings, A represents a suitable frame in which is supported the elongated tank B, having a central partition 0, which separates the tank into separate and independent vats D, and E, respectively, which vats are preferably designed to hold water having sufficient salt in order to give it the desired degree of density, the density of the liquid in the two vats being of different degrees as will be noted in connection with the devices employed in each vat, and it will of course be understood that according to the nature and character of the work required of the separator, the liquid in the separate vats will of course be changed to suit the particular work.

Arranged over one end of the vat D, which may be termed the primary vat, is the feed box or hopper F, having at its lower end the feed opening f, controlled by the adjustable gate f, and leading from the box or hopper F, is the inclined feed chute G, which projects below the surface of the liquid in the primary vat in close proximity to the inclined elevator apron H. The inclined elevator apron H, is made of suitable material such as prepared canvas, rubber or wire cloth, and is provided with the perforated elevator slatsl, connected at their ends to the opposite endless apron chains J, passing over suitably arranged sprocket wheels K. The sprocket wheels K, of the apron H, are arranged inside of the vat D, near one lower corner thereof, and di- 1 rectly above one upper edge thereof, respectively, and the upper set of sprocket wheels K, are mounted on a suitable shaft in, driven by the drive sprocket wheel L, at one end of the shaft 70.

Assuming the separator to be employed in separating green and ripe peas, the liquid in the vat D, is of a proper density so as to allow the green and ripe peas of their own specific gravity to be directed by theinclined feed board G, onto the first elevator apron H, while at the same time floating all trash and foreign matter. The trash and foreign matter which is thus separated from the peas in the primary vat D, and is floated on the surface of the liquid in such vat, is skimmed 0d of the liquid by the horizontal endless drag apron M. The endless drag apron M, carries the opposite sprocket chains m, which pass over suitably arranged sprocket wheels m", driven by means of suitable gearing, and arranged at the upper edge of the vat D, and said endless drag apron M, carries the pivoted drag blades N, which feather on the top portion of the apron, and fall into a vertical position of their own weight to drag the trash and foreign matter along the surface of the liquid up to the refuse apron O. The refuse apron O, is arranged at an incline above the elevator apron II, and has its inner end disposed directly under oneend of the horizontal drag apron M, and said refuse apron O, is carried on the end sprocket wheel 0, and is also provided with the perforated elevator slats which slats as well as the slats I, of the apron H, allow the brine or liquid to settle back onto the apron and drip back into the vat, without being elevated together with the material on such aprons. The apron sprocket wheels 0, are mounted on suitably arranged shafts journaled in the vat D, and in the frame above the shaft 71;, respectively, and the upper wheel shaft of said apron carries the drivesprocket wheel 0', over which passes the drive sprocket chain 0 The drive sprocket chain 0 also passes over the sprocket wheel L, of the shaft 70, and is driven from the main drive wheel 0 suitably arranged.

The refuse elevated by the apron O, is deposited from its upper discharging end into the transverse conveyor box P, in which turns the screw'conveyer p, which serves to carry the refuse to a point of deposit, while the green and ripe peas which are elevated by the inclined elevator apron H, are discharged from the upper end of such apron onto the perforated inclined chute board Q. The perforated inclined chute board Q, allows the liquid to drip back into the primary vat D, and at the same time directs the green and ripe peas, together, into the liquid of the secondary vat E, which liquid is of a different degree of density from that contained in the vat D, and is of such a density as to float all green peas, while the ripe peas of their own specific gravitysettle onto the lower separator apron R, and are further assisted to drop thereon by the inclined deflecting board 7'. The lower separator apron R, is arranged at an incline in the secondary vat E, and is constructed similar to the'aprons H and 0, previously described, being provided with the perforated elevator slats 'r, and passing over the sprocket Wheels r arranged on shafts r journaled in the vat E, and at a point above the same, respectively, and the upper of the shafts r carries at one end the large wheel S, over which passes the chain 3, leading from a sprocket wheel 3', mounted on the same shaft as the wheel 0. Now as the elevator apron R, turns in the direction indicated by the arrow, the ripe peas which have settled thereon will be elevated out of the vat E, and over the upper end of the apron onto the perforated discharge chute T,which is arranged underthe upper end of the apron R, at one upper end of the vat E, so that the liquid can drip back into the vat, while the chute T, being disposed at an angle, will lead the ripe peas to the point of discharge. The liquid in the vat E, floats the green peas, and such green peas are collected by the horizontal drag apron M. The horizontal drag apron M, is arranged at the upper edge of the vat E, adjacent to the board Q, and is similarly constructed in every particular to the drag apron M, previously described, and the drag blades of the latter drag apron M, carry the green peas up to the inclined upper separator apron U. The upper inclined separator apron U, is arranged in the same relative position above the apron R, with its lower end in the vat E, as the apron O, is arranged with respect to the apron H, in the vat D, and the said apron U, is arranged on the sprocket wheels a, the upper ones of which are mounted on the shaftu, at one end of which is arranged the wheel 10 over which passes the chain 3, which serves to communicate motion to both the lower and upperseparator aprons, respectively, as may be clearly seen in the drawings. The upper separator apron U, is also provided with the perforated elevator slats u which serve to elevate the green peasup and over the upper endof the apron U, and onto the perforated trough V. The perforated trough V, is arranged at an incline and discharges onto the short smooth apron W. The short smooth apron W, is suitably arranged at an incline, and while allowing the good peas to roll over the same and onto the final discharge chute X, at the same time elevates all broken peas and discharges the same over its inner end, so that such broken peas will drop onto the chute T, and be discharged with the ripe peas.

Although I have set forth the herein de- I scribed separator as operated in connection with the separation of green from ripe peas,

nevertheless it will be apparent that the same could be equally as well adapted for separating oats and barley and weed seeds from wheat, as well as being adapted for wetting wheat, and also employing chemicals, such as vitriol in the vats for the purpose of preparing Wheat, while at the same time providing for its separation from other foreign substances.

Changes in the form, proportion and the minor details of construction as embraced within the scope of the appended claims,may be resorted to without departing from the principle or sacrificing anyof the advantages of this invention.
