IMPROVEMENT IN CLQVER-SEPARATQR-S.

Specification forming part of Letters Patent No. 150,210, dated April 28, 1874; application filed June 18, 1873.

To all whom it may concern:

Be it known that 1, DAVID WVHITING, of Ashland, in the county of Ashland and State of Ohio, have invented certain new and useful Improvements in Glover-Separators and that the following is a full, clear, and exact specification thereof, which will enable others skilled in the art to make and use the said invention.

My invention relates to certain improvements in clover-separators, and particularly to the separating, discharging, and blast ap paratus connected therewith. Said invention consists in the combination, with the slatted separating-apron, of a slatted separating-platform made in two sections, one of which can be slid endwise along the other, so that, when the separating-apron is stretched, the separating-platform may retain its relative position with reference to the apron without effecting the continuity of the platform, as is hereinafter more fully shown. Said invention also consists in the combination of the sliding section of the slatted separating-platform with the stretching device of the separating-apron by means of connecting-links, as is hereinafter more fully shown, whereby the use of a separate device for operating the sliding section of the platform is made unnecessary, and the adjustment of both the apron and platform is effected at one operation. Said invention also consists in the combination, with the fan-case, of a peculiarly-constructed blast-regulator, by means of which the seeds falling through the sieves to the discharge-spout may be subjected to two distinct blasts, as is hereinafter more fully shown.

In the accompanying drawing, Figure 1 is a plan of a part of a separating apron and platform with the tightening and regulating device, a piece of the frame being broken oif to show said device. Fig. 2 is a side view of said tightening device for the apron and platform. Fig. 3 is a plan of a part of the separating-sieves, the tailing-spout, and blast-regulator, with the separating apron and platform removed. Figs. 4. are side and end views of separating-platform with its end curved plate. Fig. 5 is a section through the line a: m, Fig. 1, with that part of the frame over the fan and cylinder shown in position.

A are the longitudinal slats, which compose the separating-platform, and which are divided between the rods to a that support the adjacent ends, so as to make tWO sections, one of which, a, is stationary, while the other section a. has a slight longitudinal motion'on the crossrods B and a that work in slots in the frame pieces R, the inner ends of the slats of section a sliding alongside of the ends of the slats of section a, as shown in Fig. 1, between the rods to and a. The rod B is secured to the longitudinal slats A of the separating-apron a, and is made to slide in a slot, T, Fig. 2, by means of connecting-links G that connect the ends of the said rod with the tightening device E F f at the shaft D, which device is of the same general construction as that shown in Letters Patent 103,806, granted to me May 31, A. D. 1870, for improvements in clovermachines. H is an inwardly-concave plate,

secured to the outer and curved ends of the movable section of the separating-platform, and so arranged that, through the action of the tightening device on the movable section of the separating-platform, it is kept flush with the outer slats of the separating-apron. 1, 2, and 3 are the sections of the upper sieve, and 4 is the lower sieve, the whole making the grain-separating shoe. Q is the grain-shoe,

secured to the grain-separating shoe at its outer.

end by the swinging arms P, and hanging and swinging at its inner end on the arms 1?, which are not fastened to the grain-separating shoe, the said arrangement of the arms P P, with reference to the grain-shoe Q and grain-separating shoe 1,2,3, and 4, giving the grain-shoe Q the same longitudinal motion as that given to the grain-separating shoe by the crank-shaft L without the tilting motion given to the inner end of said separating-shoe. J is the tailingspout, made with a sharply-inclinedbottom, and securely fastened to the grain-shoe Q, so that the longitudinal swinging motion given to the grain-shoe and grain-separating shoe is also given to the tailing-spout. S S are the separating-bars, secured to the outer end of the grain-separatin g shoe, so as to project over the tailing-spout J. I is the blast-regulator of a triangular cross-section, having its broad face adjacent to the floor of the frame, and is secured at its inner end to a rod, V, journaled to the side pieces of the frame in such a posiwasted.

tion as to bring the inner edge of said regulator above the door, the regulator being raised at its outer end to admit a blast by a rod or pins, W, sliding in slots in the frame. Said regulator is located at the exit-port of the fancase, and is arranged so that its inner and upper sloping face will receive the grain falling from the sieves 3 and 4t and the grain-shoe Q, and turn it into the discharge-spout K, while over its outer faceY a blast is being given to the grain falling through the sieves, and at the same time, if desired, from under its lower face a second blast can be given to the grain as it falls from the inner and upper face of said regulator into the discharge-spout, this second blast coming out under the grain-shoe.

These several improvements operate as follows: Heretofore when the separating-apron M N has been tightened by the tightening devie E F f, the se 'iarating-platform A A has remained stationary, and'the outer end thereof was rendered in great part useless on account of its not keeping the same relative position with reference to the slats of the apron above, but leaving a considerable space between it and the outer apron-slats, through which the stemmed heads have fallen and been To remedy this I make the separatin g platform in two sections, and secure to the outer ends of the slats of the movable section the inwardly-concave plate H, which catches all the heads and turns them into the shoe below, the movable section B a of the separating-platform being connected to the aprontightening device by the bars C G. hen the operator tightens the apron by working the screws E, he also regulates the movable section of the separating-platform, and keeps it in the same relative position with reference to the apron above, the bars 0 causing the bar 13, to which the movable section of said platform is secured, to move forward or backward in the slots in the frame It It, according as the box at D is moved. The tailing-spout J is here shown as being connected to the grainshoe Q, but, if preferred, it could be connected to the grain-separating shoe, as the essential feature is to have it have the longitudinal shaking motion of the grain separating shoe and grain-shoe, in order to insure the passage of the tailings down the spout.

When there is not much dust in the heads of grain, and only an ordin ar 1 blast is required, the blast'regulator I is left in the position noted by the dotted lines; but when said blast is not sufficient to thoroughly separate the finer chaff anddust from the grain, the endY of the blast-regulator is raised when a blast of air, created by the fan (the position of which is shown by the dotted lines, Fi 5) rushes through the passage formed under said regulator onto the seeds and chaff falling from the upper and inner face of said regulator into the discharge-spout K, thereby blowing away the dust and fine chaff that may have escaped the blast above.

hat I claim as new, and desire to secure by Letters Patent, is-

1. A slatted separatin g-platform, constructed in two sections, one movable and the other stationary, substantially as and for the purpose described.

2. The combination, with a slatted separating-apron and tightening device, of a slatted separating-platform constructed in two sections, and connecting-bars O C, whereby the tightening of the apron and adjustment of the two-part slatted platform are simultaneously eflfected by one tightening device, substantially as and for the purpose specified.

3. The combination, with a slatted separatingplatform, having curved outer ends of an inwardly-curved plate, H, substantially as and for the purpose specified.

.4. The blast-regulator I, of triangular form, arranged to receive the falling grain from grain-shoe Q, and serving as the means of directin g one or two blasts of air onto the grain between its entrance into the sieves and its passage to the discharge-spout, substantially as and for the purpose specified.

DAVID WIIITING.
