GRAIN-SEPARATOR.

1,031,144., Specification of Letters Patent. Patented July 2, 1912.

Application filed November 25, 1910. Serial No. 594,110.

in position in any desired manner and in the present case I have shown the rear edge thereof as held by a metallic strip 16, secured to the shoe, said strip being turned upwardly and provided with tongues, as 17 60 which pass into the edge of the pad.

The shoe may be provided with suitable riddles or screens to grade the grain from which the garlic has been previously removed, and to that end the shoe may have a 65 screen or riddle 18 through which the finer grain may pass into a channel or opening 19 which discharges into a receptacle 20. The shoe may likewise be provided with a second screen or riddle 21, discharging i to a hop- 70 per or like receptacle 22, provided with a screw 23 to remove the grain. It will be appreciated that any arrangement of screens or riddles may be employed in the shoe.

In the operation of the device the grain 75 with the garlic therein is passed from the hopper onto the shelf and thence onto the delivery-board 6, and during the usual vibration of the shoe passes downwardly along the board 6 until it reaches the delivery end 30 thereof, when it falls. At this point the ain comes in contact with the blast being delivered by the fan, and by reason of the difference in specific gravity between the garlic seed and the grain the garlic will be 5 blown outwardly over the separating board 11, the wheat or other grain falling onto the ad 15. Said pad being non-resilient, or substantially so, prevents the wheat from jumping upwardly and passing over the 90 separating-board, as frequently occurs in machines of this character as at present manufactured. By adjusting the separating and the delivery boards a separation of the garlic from the wheat may be readily of 95 fected, this adjustment being necessary with various grades of wheat, some of which are heavier than others.

It will be appreciated by those skilled in the art that the machine shown is merely 100 typical and may be varied in many ways without departing from the spirit of the present invention.

In the use of the terms delivery and separating boards it will be understood that these 105 words are employed in a generic or general sense, and the construction is not limited to the use of boards, as such parts may be made of any other material which may be found desirable. 110

To all whom it may concern: Be it known that I, JOHN H. MURRAY, a citizen of the United States, residing at Bay View, in the county of Cecil and State of 5 Maryland, have invented certain new and useful Improvements in Grain-Separators, of which the following is a specification.

; My present invention pertains to improvements in grain se arators, and is designed more particularly or separating garlic from wheat though, of course, it may be used for the separationof various grains.

The invention in its simplest form is illustrated in the annexed drawings, wherein:

Figure 1 is a vertical longitudinal view of a separator having my invention embodied therein; Fig. 2 a perspective view of the discharge end of the machine or shoe; and Fig. 3 a horizontal sectional view, taken on the line 3-3 of Fig. 1.

In the drawings, 1 denotes the main frame or casing, provided with a hopper 2 and the usual fan .3 for delivering a blast of air through the shoe which is designated by 4:.

Carried by the shoe beneath the hopper is a shelf 5 which delivers the grain onto a delivery-boardG, said board being adjustable longitudinally, and to this end its edges are seated in grooves or channels 7 formed in the sides of the shoe, adjustment of the board being secured by screws 8 which work in bearings 9 adjacentto the outer end of the shoe, said screws likewise passing through threaded blocks 10 secured to the upper face of the delivery-board 6. By manipulating the screws, the outer ends of which are squared to receive a wrench or crank, the board may be drawn outwardly or moved inwardly as occasion may require.

Secured to the outer or delivery end of the shoe is a vertically disposed separating board 11, the board being provided at each end with a vertically disposed slot 12 through which passes a bolt 13, the bolt being fixed to the walls of the shoe and adapted to receive a thumb-nut, as 1 1, by which the separating board may be clamped in any desired vertical adjustment.

Located immediately behind the board within the shoe upon the floor of the shoe is a pad or cushion 15, said pad being preferably formed of a material such, for instance, as heavy felt or the like, which will prevent the grain, when dropping upon the same,

from rebounding. This pad may be secured Having thus described my invention, what I claim is:

1. In a separator, the combination of a member upon which the grain is placed and caused to travel; a fan for forcing a blast of air beneath and past the delivery-end of said member; and a cushion onto which the grain falls from said member.

2. In a separator the combination of a member upon which the grain is placed and caused to travel; a fan for forcing a blast of air beneath and past the delivery endoI said member; a separating board located in front of and below. the delivery end of the said member; and a cushion located in line with the said delivery endand in rear of the separating board.

3. In a separator, the combination of a supporting frame; a delivery-board located therein; means for securing longitudinal adjustment of said board; a vertically-adjustable separating board; a cushion located in rear of the separating-board'and beneath the discharge end of the delivery-board and a fan for forcing a current of air through the space formed between the edges of the two boards.

45. In a separator, the combination of a frame; a delivery-board; means for securing longitudinal adjustment thereof; a vertically-disp0sed separating or division board; means for securing vertical adjustment thereof; and a fan for forcing a blast of air through the space formed between of the two boards.

5. In a grain-separator, the combination a Copies of this patent may be obtained for five cents each, by addressing the Washington, D.

adapte o receiv 'tical plane relatively the edges,

producing. a blast; means for to the said blast; a cushion e the grain as it is dropped of means for feeding grain through the separating blast. 4 6. Ina separator, the combination of a longitudinally adjustable grain feeding board; a separating board located below and in front of the discharge end of the feeding board, said separatingboard standing in a substantially vertical position and in a verclose to the discharge end of t'he feeding board; and means for forcing a blast of air between the adjacent edges of said boards. i

In a separator, the combination of a supporting frame; a shoe suspended therein so that thesamemay be shaken or oscillated; a longitudinally-adjustable member carried by the shoe and upon which the, grain is placed to be caused to travel; a substantially vertically-disposed separating board located in front of and below the adjustable member aforesaid and likewise carried by the shoe; means for securing vertical adjustment of said separating board; and means for causing a blast of'air to pass out through the opening formed between the upper edge of the board andthe discharge end ofthe longitudinally-adjustable member. 5

In testimony whereof,- I have signed my name to this specification in the presence of two subscribing witnesses.
