IMPROVEMENT IN HARVESTERS.

specification forming part of Letters Patent No. 41,080, dated'J-anuary 5, 1864; reissue No. 6,223, dated January 12, 1875; application filed December 10, 1874.

DIVISION A.

To all whom it may concern:

and WILLIAM W. MARSH, formerly of Shahbona, in the county of De Kalb and State of Illinois, now of Sycamore, in said county and State, have inventeda new and Improved Rakin g Device for Harvesters; and we do hereby declare that the following is a full,'clear, and exact description of the same, reference being had to the accompanying drawings, consisting of two sheets, making a part of this specifioa tion, in which- .Figure 1 is a top or plan view, and Fig. 2 a front elevation;

To enable others skilled in the art to make and use. our machine, we will proceed to describe it.

Arepresents a horizontal rectangular frame,

in which a horizontal band, B, is placed and fitted over rollers a a. This band or carrier B extends over the whole width of the space in frame A, as shown,-- and moves in the direE- tion indicated by the arrow 1. 0 represents the sickle, which may be of the ordinary reciprocating kind, and works at the front of the frame A. This sickle is provided with a series of upright ribs' or projections, 11, attached to its back part, the upper edges of which-(said ribs or projections) are inclined, so as to leave a vertical face, 0, at one end, while the upper edges are inclined downward and backward, as shown at Fig. 2. D represents an endless toothed apron, or what may be termed an endless ,band of rakes. This toothed apron D has'an inclined position, and works over rollers d d, one of which, d, has its hearings in the frame A, and the other, cl, in an upright frame, E, which is attached to the frame'A.

The toothed apron D moves in the direction indicated by the arrow 2, and the aprons or carriers D B are moved by power applied to the upper roller, (1, of the apron D, motion being communicated from the roller d totone of the rollers a by a suitable belt, 0. The puI-J leys ff, over which the belt 0 passes, are of different diameters, the pulley f of the rollerd being of a larger diameter than the pulley f of the roller a; hence it will be seen that the band B will move faster than the toothed apron D.v F is a belt, which passes around pulleys g g at the ends of the rollers d d, and they are extensions of said rollers, This belt is provided with teeth h at suitable distances apart. This belt F forms a part of the elevator, and projects forward in line, or nearly in line, with the front edge of the sickle (J.

In operation, as the harvester is drawn along, the grain cut by the sickle 0 falls upon the band or carrier B. This band, by its movement, conveys the grain to the toothed apron D, the butts of the grain being at the front edge of this band or carrier B. The grain, owing to the movement of the belt, does not fallon the carrier at right angles with the sickle O or band B, but will fall more or less obliquely, according to the position in which it may stand when out, and the rapidity with which the carrier B moves, the heads of the grain being in advance. The grain or straw is brought at, or nearly at, right angles with the band B by two different means, one being the ribs or projections-boil the back of the sickle G, which, as the sickle moves back, pass under the butts of the straw, and on the return movement catch in the butts and move them forward toward the elevator D F, which movement is repeated at each stroke of the sickle. The other means of straightening the grain, or bringing the straw parallel, consists in the difference of speed between the band or carrier B and the toothed apron D. In consequence of the former having a faster movement than the latter the grain will be straightened and brought at, or nearly at, right angles with thelower edge of the toothed apron, so that the grain will ascend, or be carried up by the elevators F D, and delivered uponthe receiver inthe position required for binding. The movement of the grain in the inclined position in which it falls and the straightenof the stalks, and prevents them from lagging or falling over. Thus it will be seen that the grain will be discharged from the upper end of the elevator D F with the straw all p'arallel, or nearly so, with it, and the grain, consequently, can be taken from the box or receptacle, into which it is discharged in an even state, so that it may be bound with facility.

G G represent the binders table or tables, secured to the frame A. The receptacle into which the grain is discharged (not represented) may be just below the upper elevation or end of the toothed apron D.

What we claim as newis as follows:

1. The combination of the sickle 0, provided with the ribs or projections 11, with the endless band B and toothed apron D, substantially as and for thepurp'ose specified.

2. The toothed belt F, in combination with the toothed apron D andendless band B, as and for the purpose specified.

3. A grain-elevating mechanism having its front part arranged to operate on or near to the'cutting line, substantially as and for the purpose specified.
