SEPARATOR-GRATE.

SPECIFICATION forming part of Letters Patent No. 764,669, dated July 12, 1904.

Application filed January 11, 1904. Serial No. 188,446. (No model.) 7

To (1.7], whom, it may concern:

Be it known that I, NICHOLAS FMn'rz, a citi- Zen of the UnitedStates, and a resident of Ashton, county of Spink, and State of South Dakota, have invented certain new and useful Improvements in Separator-Grates Used in Grain-Threshing Machines. Separators, and the Like, of which the following is a specification.

My invention relates to that part of a threshing-maehine or separator commonly called the grate and lies adjacent to the toothed cylinder and near the beater.

The object of my invention is to provide an adjustable grate so arranged that the space between the several members may be adjusted and also so constructed as to tend to spread the grain and distribute the same over the entire width of the machine and eliminate any tendency of the straw to clog on the grates.

To this end my invention consists in the novel construction, arrangement, and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a plan view of my grate arranged to give the greatest space between adjacent members. Fig. 2 is an elevation taken from immediately back of the finger-rotating mechanism of Fig. 1. Fig. 3 is a partial sectional view of a separator equipped with my invention and taken substantially on line 3 3 of Fig 1 and shows the relative position of the grate with the toothed cylinder and beater. Fig. 4 is a plan view of my grate arranged to give the least space between adjacent members. Fig. 5 is an elevation taken from immediately back of the finger-rotating mechanism of Fig. 4:. Fig. 6 is an end elevation of one of the members or fingers detached. Fig. 7 is a side elevation of the member or finger shown in Fig. 6 in combination with the supporting and elevating mechanism. Fig. 8 is an end elevation of one of the central members with the supplemental member attached. Fig. 9 is an end elevation of one of the members or fingers ot' amodified form.

As shown in the drawings, my improved grate comprises two sections, each beginning at substantially the center of the machine and extending to the adjacent side. Each section is provided with a plurality of bars or fingers 1, extending in a direction longitudinalot the machine and slightly diverging toward the adjacent side. In the preferred form shown each finger is provided with a rounded shank 2, rotatably mounted in a transverse bar 3, which is itself pivotally supported to permit the free ends of the fingers 1 to be vertically adjusted, for a purpose hereinafter explained. The shank 2 has its end I bent at an angle thereto, and suitable means are provided to engage the ends I and by moving them in unison rock the fingers on the shanks 2, and thus control the adjustment of the several fingers, and consequently the space between them. As the several fingers are adjusted toward a position arranging them upon their edges, as shown in Figs. 1 and 2, the space between them Will be increased, and the effect of directing or throwing the straw toward the side of the machine will also be increased. As they are adjusted in the opposite direction, as shown in Figs. 4: and 5, the part of the fingers adjacent to the shank may be laid practically flat, and the space between them is reduced. Obviously the two sections should be operated in opposite directions, and any suitable means may be employed for that pur pose. In the preferred form shown the extensions 4 ineach section are attached to a bar 5, while a rod 6, extending to the exterior of the machine and there provided with a hand-wheel or equivalent means for convenience in operating the same, is provided with right and left threaded portions 7 8, engaging similarly-cut nuts secured to the bars 5. By rotating the rod 6 in either direction the bars 5 will be IDOVGCl longitudinally, partially rotating the fingers l, as set forth, and adjusting them as desired. The fingers on Suitable means may be provided for supporting and vertically adjusting the free ends of the fingers. As shown, a transverse bar 10 is passed beneath the fingers, said bar being offset at the ends 11, pivotally supported, as at 12. and provided with a lever 13, by means of which the bar 10 may be vertically adjusted as desired, thus providing for the vertical adjustment of the free ends of the fingers 1 forming the grate. Any suitabls means may be provided for securing the lever 13 and the connected parts in their adjusted position. As shown in the drawings, a guiding-segment 14, provided withaclamp-screw, is provided for the purpose.

The usual position of the adjacent cooperating parts is shown in Fig. 8, in which 16 represents the cylinder, 17 the usual transverse grates or concaves, (shown also in Figs. 1 and 4,) 18 the beater, 19 apart of the strawracks, and 1 to 13 is my grate showing in its normal position and in broken lines the manner in which the free ends of the fingersmay be elevated to throw the straw higher into the beater. In the preferred form of the fingers 1 (shown in Fig. 7) they are aslo given a slight twist to more thoroughly direct the straw toward the two sides of the machine, and thus equalize the distribution of the straw over the grate. If desired, a similar operation may be secured by forming the finger and its shank at a slight angle, as shown in Fig. 9.

The bar 3 may be pivotally supported in any suitable manner. As shown in the drawings, it is secured to a rod 20, extending transversely across the machine and supported in the outer walls thereof.

As the free ends of the fingers are vertically adjusted as described, the bars?) 5 are swung in the arc of a circle, and the rod 6 is provided with a flexible coupling 21 of any preferred construction to readily permit of such a movement.

It is obvious that after having thus described my improvement various immaterial modifications may be made withoutdeparting from the spirit of my invention. HenceI do not wish to be understood as limiting myself to the exact form and construction shown.

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