SPECIFICATION forming part of Letters Patent No. 235,229, dated December 7, 1880.
Application filed April 13, 1880. (N0 model.)
tion, such as will enable others skilled in the.
art to which it appertains to make and use the same, reference being had to the accompanyin g drawings, and to letters of reference marked thereon, which form a part of this specification.
My invention has relation to an improvement in grain-separators; and it consists of a frame having transverse partitions of a graduated width arranged with reference to a blastfan and a sieve or sieves, and of certain minor details, substantially as hereinafter more fully described and claimed.
The object of my invention is to change the blast created by the blast-fan from an outward or horizontal direction to an upward or vertical one, to cause the currents of air to be more equally distributed to the sieve or sieves, to prevent the sieve or sieves from clogging, to cause the more speedy separation of the chaff from the grain, and to prevent the grain being carried off with the chaff.
In the annexed drawings, Figure 1 is a longitudinal vertical section of the shaker of a grain-separator with my draft conductor and equalizer arranged therein below the upper sieve, and Fig. 2 is a perspective view of the draft conductor and equalizer.
Corresponding parts in the two figures are indicated by similar letters of reference.
Referring to the drawings, A marks the shaker, B an upper riddle or sieve, and O a lower riddle or sieve, of a grain-separator, all of the ordinary construction.
Arranged in the shaker, immediately below the upper sieve, B, is my draft conductor and equalizer, composed, in the present instance, of two side pieces, D, having a number of transverse partitions, d, which are graduated in width, the narrowest being at the front or fan end of the shaker. This frame may be removably secured in the shaker by means of a pin, d, passing down through the sieve B and frame, or it may be firmly secured therein by wood-screws, &c. The lower ends of the partitions may be beveled, as shown, to cut the currents of air more sharply.
As the blast of air created by the fan enters the front end of the shaker it strikes against the graduated transverse partitions d, which deflect or change the currents from a horizontal to a vertical direction, when they pass through the sieve and lift the chaff therefrom, which permits the grain, unclogged by chaff, to roll down the screen into a suitable receiving-vessel.
The graduated partitions also cause the currents of air to be directed through the sieveB as forcibly at the farthest end of the sieve as at the front end, by which the draft is equalized and the clearing of the chaff from the grain is rendered more thorough.
It is manifest that instead of the side pieces, D, a frame constructed in many different ways to suit the various grain-separators may be used without departing from the spirit of my invention; also, that the partitions may be obliquely arranged in the side pieces instead of being arranged at right angles, as shown, and that any number of partitions desired may be used.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
1. In a grain -separator, the combination, with a blast'fan and a sieve or sieves, of the transverse partitions of graduated widths, substantially as and for the purpose set forth.
2. In a grain-separator, the draft conductor and equalizer having transverse partitions of graduated widths arranged below an upper and increasing in width from the front or fan end of the shaker, substantially as and for the purpose set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 31st day of March, 1880.
JEFFERSON GRUBE.
