SPECIFICATION forming part of Letters Patent No. 431,269, dated July 1, 1890..

Application filed September 1'7, 1889. Serial No. 324,252, (No model.)

To on whom it may concern:

Be it known that I, EDWARD LEsLIE, of Orangeville, in the Province of Ontario, Dominion of Canada, have invented a new and 5 Improved Separator, of which the following is a full, clear, and exact description.

The invention relates to machines for separating grain, gravel, &c.

The object of the invention is to provide a to new and improved separator, which is simple in construction, very effective, and durable 1n operation.

The invention consists of a screen mounted to swing and having an intermittent fast and slow motion.

The invention also consists in certain parts and details and combinations of the same, as will be described hereinafter, and then pointed out in the claims.

' Reference is to be had to the accompanying 2 5 ment. Fig. 2 is a sectional side elevation of the same, and Fig. 3 is a plan View of the same.

The improved separator is easily adapted for fanning-mills and other machines used for separating grain, gravel, the. As illustrated in the accompanying drawings, it is intended for separating sand from the coarse gravel, the material being shoveled from the pit into elevator-buckets, carried upward by 5 the latter, and discharged into the screen which separates the sand from the coarse gravel, and the latter passes directly from the screen into the wagon or car arranged under the lower end of the screen or connected with 0 the latter by a channel or other device. The sand can pass from the screen to a wagon or car standing directly under it.

The improved separator A is provided with a suitably-constructed frame B, which supports the upper end of the elevator C, resting with its lower end on the ground.

The elevator C isof any approved construction and provided with suitable buckets connected with each other to form an endless carrier D, passing over the lower wheel or roller E and the upper wheel or roller F, both mounted to turn in suitable bearings on the frame of the elevator C. 011 one end of the shaft G of the upper wheel F is arranged a pulley H, adapted to be connected by belt or 5 5 other means with other machinery to drive the said shaft G by power, or a crank-arm I may be attached to the said shaft to turn it by hand. WVhen the shaft G is rotated, the carrier D of the elevator is set in motion and the filled buckets carry the material upward and discharge the same over a transverse inclined board J onto an inclined screen K, mounted to swing between the sides L L of the screen-frame L, connected at one end with 6 5 the upper end of the elevator-frame and supported at its other outer end on posts L The screen K is hung at its sides at or near its upper and lower ends on links N, pivoted on suitable brackets 011 the frame L and on the upper end of the frame of the elevator C, as shown. The links N are preferably so arranged that when the screen is in its innermost position the said links stand vertical, and when the screen is on its outward stroke it moves outwardly and upwardly,.as shown in dotted lines in Fig. 2. A pitman 0, located on the under side and preferably in the middle of the screen K, 0011- neots one end of the latter with an arm P, secured on a transversely-extending shaft Q, mounted to rock in suitable bearings held on the sides L and L of the frame L. On one outer end of the rock-shaft Q is secured an arm R, pivotally connected with a rod S, eX- tending along the outside of the side L toward the elevator C, having its free end guided in one of the bearings T, T or T formed on the bracket T, secured by screws or bolts to the side of the frame L. 011 the outer end 0 of the rod S is formed a lug S, engaging the lower end of an arm U, pivoted at its upper end at U on the outside of the elevator-frame. The arm U is provided near its middle with a bend U adapted to be engaged alternately by a series of pins V,secured on the face of a disk V, fastened on one end of the shaft G. The pins V are preferably arranged in a circle and placed equidistant apart, as shown in Fig. 1.

The arm R is connected with one end of a spring W, secured at its other end to a side of the frame L. This spring WV serves to impart a quick outward and upward motion to the screen K as soon as the bend U of the arm U is passed by one of the pins V on the disk V, in the mannerhereinafter more fully described.

The operation is as follows: A rotary motion in the direction of the arrow a is imparted to the shaft G, so that the carrier D of the elevator discharges the material to be separated on the swinging screen K, which,

has a slow rearward stroke and a rapid outward stroke, and receives a sudden jerk or bump at the end of the outward stroke. IVhen one of the pins V in the disk V, which ro-l tates with the shaft G in the direction of the arrow at comes in contact with the outer part ward and downward into the position shown 1n full lines in Fig. 2. The moment the pin V passes the bend U of the arm U the latter is set free and swings quickly in the inverse direction of the arrow 1) until its bend U strikes the next following pin V.

This

movement of the lever U is caused by the j action of the spring \V on the arm R, con nected by the rod S with the said lever U, as 1 before described, the said arm Rbeing swung in the inverse direction of the arrow c.:

This movement of the arm R turns the shaft in the same direction, whereby the screen is moved quickly outward and upward on ac count of being connected by the pitman O,

and arm P with the said shaft. ment of the arm U in the inverse direction of the arrowb' issuddenly interrupted byits bend j striking against the next following pin V, so that a similar short stop orjerk is given to the screen K by the connection before mentioned.

The move- The material deposited by the elevator-can,

rier D on the upper end of the inclined screen receives a quick and sudden shaking and momentary displacementon the screen, whereby the coarser and finer particles easily separate, and the finer particles pass through the meshes of the screen to a wagon, car, or

other receptacle standing on the ground below. The remaining coarser parts move downward on the inclined screen K, their downward movement being hastened by the successive sudden jerks on the outward and upward movement of the screen K. The coarser material finally passes over the lower end of the screen K into a wagon or car standing below, or into a channel leading from the end of the screen to a Wagon, car, or receptacle located at some distance from the machine.

If the machine is used on fanning-mills, for instance, the material to be separated passes through a hopper onto the upper end of the swinging screen K. The throw of the screen can be increased or diminished by placing the free end of .the rod S in a different bearin g T T or T on the bracket T, as the said bearings are arranged radially relative to the joint of the rod S with the arm B. When the rod S is guided in the bearing T, the lug S is in contact with the arm U ata point nearer the fulcrum U of the said arm U, so that the throw imparted by the latter to rod S, and consequently to the screen K, is less than when the rod S is guided in the bearings T or T, as in the latter case the connection of the said rod S with the arm U is farther from the latters fulcrum, and the throw consequently greater.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a separator, the combination, with an elevator of a screen mounted to swing and a disk secured on one of the elevator-shafts and provided with pins, of a pivoted arm provided with a bend to be successively engaged by the said pins, a rod connected with the said pivoted arm, and intermediate mechanism for connecting the said rod with the said screen to impart an intermittent fast and slow motion to the same, and a guide-bracket provided with a series of bearings for the said rod to increase or diminish its throw and that of the screen, substantially as set forth.

2. In a separator, the combination, with a disk provided on its face with pins, of a pivoted arm provided with a bend adapted to be successively engaged by the said pins, a rod connected with the said pivoted arm, a rockshaft connected with the said rod, a spring pulling on the said rod, and ascreen mounted to swing and connected with the said rockshaft, substantially as shown and described.

3. In a separator, the combination, with a disk provided on its face with pins, of a pivoted arm provided with a bend adapted to be successively engaged by the said pins, a rod connected with the said pivoted arm, a rockshaft connected with the said rod, a spring pulling on the said rod, a screen mounted to swing and connected with the said rock-shaft, and intermediate mechanism for connecting the said screen with the said shaft, substantially as shown and described.

4. In a separator, the combination, with a disk provided on its face with pins, of a pivoted arm provided with a bend adapted to be successively engaged by the said pins, a rod connected with the said pivoted arm, a rockshaft connected With the said rod, a spring pulling on. the said rod, a screen mounted to swing and connected With the said rock-shaft,

and an adjustable guide-bracket for the said rod to increase or diminish its throw, substantially as shown and described.
