IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 143,609, dated October 14, 1873; reissue No. 5,8 [0, dated March 31, 1874 application filed February 12, 1874.

To all whom it may concern:

Be it known that we, EDWIN BAYLISS, J AMES 0. BROWN, and FRANgoIs '1. LoMo 'r, all of Massillon, county of Stark, State of Ohio, have invented certain new and useful lmprovem cuts in Harvesting-Machines, of which the following is a full, clear, and exact description,reference being had to the accompanying drawing making part of this specification, in which Figure 1 is a perspective view taken from the rear of the machine, with a portion of the elevator-flame broken away to show the elevator-aprons and chute-board. Fig. 2 is a perspective view taken from the front, with the canvas aprons removed. Fig. 3 is a front elevation, showing the arrangement of the belts or canvases; and Fig. 4 is a perspective view of the hinged binders stand or platform, and its hinged guard or win g-board, detached from the machine.

Similar letters of reference denote corre spouding parts in all the figures.

The invention has for its object the im provement of that class of machines upon which the binders ride for the purpose of binding the grain as it is cut; and relates, first, to the construction and arrangement of the hinged binders platform; second, to the construction and arrangement of the binders table; third, to the arrangement of a chute or deflecting board in combination with elevator-aprons.

In the accompanying drawing, A represents the forward transverse bar of the frame, and A the rear transverse bar, both, by preference, being made to extend the entire width of the machine, and, in connection with the outer longitudinal bar A inner bar A and gear-plank A constituting the frame of the machine. B (see Fig. 2) is a. flooring underneath the carrvin -a ron B extendin from the sill A to the end board B and forming a grain-box, or receptacle to receive the shattered grain and heads,and to protect the canvases. O O are the slatted elevator-aprons.

The rollers at the upper ends 'of these aprons are connected with each other bycogged gears, and are driven in opposite directions, at equal or substantially equal speeds, by a belt or chain, 0", from any convenient driving-pulley or sheave. c is a tightening-pulley, employed to give the requisite tension to the drivingbelt. The lower end of elevator-apron O tends, by preference, a short distance below .the upper surface of the carrying-apron B, in

order that the grain may be readily picked up between the two vertical aprons O U; and the upper end of apron C is somewhat higher than the upper end of apron 0, so that the grain, after passing upward with and between these aprons O and (3, may easily escape toward the binders table D. The equal, or substantially equal, speeds of the two aprons (J G prevent friction and the shelling of grain. c" is a chute-board, arranged in an inclined position above the elevating-aprons, for the purpose of deflecting the grain and insuring its proper delivery to the binders. We prefer to support this chute-board upon pivots placed at each end, and to secure it at any desired angle relative to the elevating-apron, as the condition of the grain may require. The rollers of apron C may be mounted at their front ends in horizontal, or nearly horizontal, slots, and are pressed toward the rollers of apron U by springs, which permit them to yield to ac commodate bunches of grain, weeds, or grass. This construction is not essential at the rear end of the lower roller of apron O, as we have found, in practice, that the grain is straightened and delivered in a better manner by having the rear end of this roller placed as close to that of apron O as may be, and still permit the grain to pass. As it is sometimes desired to make the upper end of apron 0 adjustable horizontally relative to aprons O, we propose to mount the upper roller of apron O in arms which vibrate about the upper roller of apron O, (or in slots which shall be the equivalent of such arms,) in such manner that the aprons may spread apart without throwing the driving-gears out of mesh. The roller may be held in position, when adjusted, by setscrews. For the purpose of stiffening the elevator-frame, and of supporting the apron 0 against undue deflection or bagging, we employ a rack of bars, 0 (see Fig. 2,) arranged between the two parallel sides of the apron, the horizontal bars being framed intothe vertical posts of the elevator. c is an angle-iron, to support the frontelevator-post at some distance forward of the carrying-belt B. D D

is the binding-table, provided with apertures D D in which the binders stand, or place their legs when they sit on the outer portion of the table. D is a guide-board or fender,

- placed ,in a vertical position, in as close proximity as possibleto the apron G, to prevent the grain from being drawn from the table by the outer portion of said apron. d" is a rim extending around the edge of the table, and d are similar rims or ribs around the manholes D to prevent the escape of such thrashed grain and heads as may accumulate upon the table.

The binding-table is made in two. parts, as indicated at 00 co, the portion D being hinged to the portion D, and supported in a working position by posts (1 from a foot-platform, E, which will be described. F is the main driving-gear and carrying-wheel mounted on the main axle, and from which, through any suitable or usual arrangement of gearing and pulleys, motion is imparted to the sickle, and also to the platform and elevator-aprons. The foot-platform E is placed upon the gear-plank A, and secured thereto by detachable hingefastenings, in such manner that it (the platform) can be removed or can be swung up against the posts I) b when the machine is passing through a gateway, or it is desired to get access to the crankshaft, secondary shaft, or gearing which is mounted on the gearplank, and is covered by the platform.

In Fig. 4 this foot-platform is removed from its position on the machine, to show more plainly the construction and relation of parts.

E is a vertical wing board hinged to the inner edge of platform E, and serving as a guard to prevent the feet of the binders from coming in contact with the driving-wheel E. When the machine is at work, the wing-board is secured to posts b by hooks, or their equivalent, and is smaller than platform E, so that it can be folded closely upon said platform within the rim or flange e. H is the tool-box, made of less width than the space between the elevator and the drive-wheel, so as to leave room for such shattered grain and heads as may be carried up by apron G and are not thrown on the table to fall into the receptacle formed by the floor 13. I is the drivers seat, supported upon the top board or cap K of the elevatorframe.

connected with one end of a rock-shaft, i. A link, 1 connects the opposite end of the crankshaft or rockshaft with a second crank-shaft, 1 and a link, i, connects the opposite end of i this second crank-shaft with the pivoted ton gue mechanism. From the inner end of this apron 1 is a hand-lever, arranged within convenient reach of the driver, and

,it is taken by the elevating-aprons G O and delivered to the binders. As it passes from the upper end of this elevator, it strikes the chute-board 0 and is thereby deflected from a vertical path and thrown upon the binders table D. The hinges by which the two portions of the binders table are united are placed on its under side, so that the part D" will hang down when the posts 01 are removed, in order that the platform E can be folded up against posts I) and kept in place by the weight of the part D hanging against it. By making the two longitudinal sills A A to extend the entire width of the machine, the frame is made very stiff, and is much cheaper than those constructions in which the corresponding sills are made in two pieces and then bolted together.

As the machine is sometimes tilted forward to get the cutters down near the ground, it occasionally happens it is difficult to pass obstructions which are met in the path traveled by the driving-wheel, because the squared girt will not easily surmount and slide over stones or hillocks of earth. To remedy this difficulty, we extend the gear-plank A and bar A at the stubble end of the machine a short distance in front of the girt, and then place a board, A in an inclined position, extending from the lower edge of the girt A to the upper edge of the gear-plank and girt, or thereabout, forming a shoe to assist the front of the machine in mounting obstructions.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The hinged binders platform E, provided with the hinged wing-board or guard E, substantially as and for the purpose set forth.

2. The hinged binders platform E, adapted to fold upward into a vertical position, in combination with the hinged portion D of the binders table, adapted to fold downward over and to retain the folded platform E in its vertical position, as described.

3. The longitudinally-divided table D D*, constituting both the grain-receptacle and binders" table, constructed substantially as describedthat is to say, provided with the separate apertures or man-holes D D for surrounding and supporting the binders upon all sides, as set forth, and having the part D hinged to the stationary part D, substantially as described, so that it may be folded into a vertical position for transportation or for passin g through gates, as set forth.

4. The combination, with the elevatingaprons (l O, of the pivoted chute-board 0",

arranged over the upper rollers, and adapted to be set at any required angle for deflecting the grain, substantially as set forth.
