ORVILLE F. KIME, 0F CRESTLINE, OHIO, ASSIGNOR TO THE INTERNATIONAL MANU- FAGTURING COMPANY, OF CRESTLINE, OHIO, A CORPORATION OF OHIO.

SEED-CLEANING IVIAGI'IINE.

Application filed June 21, 1913.

To all whom it may concern:

Be it known that I, ORVILLE F. KIME, a citizen of the United States, and a resident .of Crestline, county of Crawford, and State of Ohio, have invented a new and useful Improvement in Seed-Cleaning Machines, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The present invention deals with an improved mechanism for cleaning the screens and increasing the efficiency of a seed cleaning machine of the usual type which is in such common use that it is unnecessary to describe it in detail.

T o the accomplishment of this and related ends, said invention then consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawingsand the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings: Figure 1 is a side elevation of a seed cleaning machine having my improved mechanism attached. thereto; Fig. 2 is a similar elevationshowing the opposite side to that illustrated in Fi g. 1; Fig. 3 is a section taken inside of the frame and looking in the same direction as in Fig. 1; and Figs. 4 and 5 are sections showing the details of the construction, the sections being illustrated by the lines 4c4 and 55 respectively in Fig. 3.

The general construction of the machine can be best seen from Figs. 1 and 2. A suitable frame 1 is provided, substantially rectangular in elevation, and in this frame there are movably mounted the screens for cleaning the seeds and also the blast mechanism for removing the lighter materials when they have been separated from the seeds. The machine in its general arrangement and construction is identical with other machines previously in use, and as these machines are widely used it is unnecessary to describe at length either the particular construction or the operation of the mechanism.

In the frame 1 there is rotatably mounted Specification of Letters Patent.

a driving shaft Q-adapted to be driven through a belt 3 by any suitable power means. Parallel to the driving shaft there is mounted a second shaft 5 which extends transversely of the frame and is connected to drive the screen operating mechanism to be hereinafter described, the shaft 5 being driven from the shaft 2 by suitable connections such as a belt 15.

Upon suitable cross-bars 16 in the fram there are pivotally attached supporting membersli which pivot-ally support a carriage 7, such carriage being provided with inclined guiding slots 8 in which there are removahly mounted screens 9 and 10, the upper 9 of the two screens being of a coarse mesh, while the lower 10 of the two screens is of much finer mesh.

The means for reciprocating the carriage upon which the screens are mounted, consist of eccentrics 70 attached to the driving shaft 2 and operating in circular eccentric straps 11 attached to rods 12 which are pivotally attached to the carriage. Rotation of the driving shaft reciprocates the carria e rapidly and through a very short distance, thus shaking the material which is placed upon the upper screen through a hopper 14 attached to the upper part of the frame and controlled by means of a slide 71 operated through a rack 17 and a gear 18, the gear being provided with a knurled nut 19 to serve as a handle. The action of the upper screen is to permit the seeds to fall through the apertures, while the larger material such as small stones, sticks, etc, is carried to the vertically lower end of the screen, the screens being inclined in the carriage, such waste material then being dis- 7 charged at the side of the machine through a chute 20 which is attached to the carriage at the lower end, and extends through an opening 21 in the side of the frame. The action of the lower screen is to some extent exactly like that of the upper in that the seeds are permitted to fall through the screen, after which their disposition is similar to the usual methods of such'machines. A fan 22 is provided in the frame to produce the blast in the passage formed by the walls 23, the fan being suitably connected to the driving mechanism. The waste material which is not permitted to drop through the second screen is discharged at the end of 1 carriage 7.

the same, through a second chute 24 which delivers at the opposite sideof the frame. It is considered unnecessary to describe at greater length the operation of the screens and the means for producing the blast and controlling the same, since these means are well known in the art.

- It is desirable to clean the screens at intervals during the operation ofthe machine, as they become filled with broken seeds and the waste material which is not shaken down to the lower end of the same. For this purpose I have provided brushing means which are movably mounted in the frame and operated whenever it is desired, from the driving shaft.- Upon either side of the frame 1, there is mounted a guide upon which there is slidably mounted a crosshead 31, such cross-heads being connected frame through slots 33 in the sides of the The rods 32 are rotatably mounted in the cross-heads, and at right angles to either rod there are attached other rods 34 which are pivotally attached to the side members 35 of a carrier, such carrier extending in a direction substantially parallel to the direction of the screens, there the forward end of the frame.

being two side members at either side of the framefeach of which is attached by means of the rods mentioned, to the cross-heads. .Beneath the carrier there is rotatably mounted a shaft 86 which is controlled by means of an arm or handle 37 slidablyand adjustably engaging a guide 38 in the form of an are attached to one of the cross-members on A setscrcw' 39 is provided for the, purpose of fixing the position of the handle on the arc. Attached. to the shaft are two lever arms 40 which are bent at right angles thus permitting them to move in the slots 41 which are cutvertically in the sides of the frame. To the outer ends of such rods are attached two bars 42 which are slidable in a vertical direction in'sockets 43 attached to the sides of the frame, such bars 42 being attached to guides or tracks 44, which support the side carrier bars of the frame 35, by rods extending through other slots 41 "in the frame." One guide 44, supports each carrier side bar, the latter, being slidable thereon. The shaft 5 is driven from the power shaft by means of the belt 15, and is provided at the other side of the machine "with a bevel gear 51 which engages a second and similar bevel gear 52 attached to a short vertical shaft 53, such shaft being provided at its upper end with a worm 54engaging a worm gear 55 attached to a third shaft 56 rotatably mounted transversely in the frame and extending through either side of the'same. To such third shaft 56 are attached short radially extending arms 57 i which are pivotally attached to connecting rods 58, the latter being pivotally attached to the cross-heads 31 sliding on the guides 30. Rotation of the power shaft 2 thus simultaneously operates the second shaft 5, and through this the third shaft 56 which thereby reciprocates the carrier upon its guides. The screens are formed in a plurality of compartments by means of transverse partitions 60, and the side bars 35 of the carrier are provided with notches or'sockets 61 in which there are removably placed brushes 62, each brush being so disposed that it will operate across the entire surface of a single compartment in the screen upon operation of the mechanism, and will travel lengthwise with the meshes of the screens.

It is scarcely necessary to describe the operation of the screens and the brushes at greater length, as the operation of the power shaft reciprocates the screens rapidly and through a short distance, while it simultaneously reciprocates thecarrier bearing the brushes more slowly and through a greater distance whereby each brush is permited to operate across the entire surface of its corresponding compartment in the screen.

and in practice the screens will be brushed at definite intervals depending upon the amount of waste material which tends to clog up thesmall openings in the screens.

\Vhen it is desired to restrain the operation of the brushes on the screens, this can be done by moving the handle 87 attached to the shaft 36 into its upper position, thus lowering the brushes away from the screens and preventing any contact between them.

By moving the handle into its lower position, the brushes are raised until they contact the screens with a suitable pressure when the handle may be maintained in this position by adjusting the set-screw 39. The pivotal connection between the reciprocating cross-heads and the carrier permits uninterrupted operation of the carrier upon its guides irrespective of the position of the guides.

The rods 45 are held in engagement with gards the mechanism herein disclosed, prothe rods 42 by set screws 80, this attachment vided the means stated by-any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention:
