ADJUSTABLE WIND-BOARD FOR HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 386,803, dated uly 31.1888.

Application filed March 10, 1887. Serial No. 230.426. (No model.)

To all whom it may concern.-

Be it known that I, HENRY J. CASE, of Auburn, in the county of Cayuga and State of New York, have invented certain Improvements in Adjustable XVind-Boards forHarvesters, of which the following is a specification.

lhis invention relates to that class of shields or fenders commonlyknown as wind-boards,

which stand vertically across the rear end of 10 the harvester-platform parallel with the cutterbar, to prevent the grain from being blown out of position; and the invention consists in an improved manner of constructing, supporting, and adjusting the windboard, so that it [5 may be moved forward and backward at the will of the operator.

In the accompanying drawings, Figure l is a rear elevation ofa portion ofa harvester provided with my improvement. Fig. 2 is an elevation of the machine, looking from the platform, which is shown in crosssection, toward the elevator. Fig. 3 is a side view of the handlever and its adjuncts by which the windboard is adjusted. Fig. 4: is a top plan view of the board and its supporting and adjusting devices.

I have represented my windboard in connection with a harvester of the class in which the grain is delivered at the inner end of the 0 platform to an elevator, by which it is carried over the main wheel, and in which the drivers seat is sustained on a horizontal plank at the inner side of the elevatorframe, over the inner end of the platform.

5 As the machine itself may be in all respects of ordinary construction, I have deemed it necessary to illustrate in the drawings only those parts with which the wind-board is immedi ately connected.

Referring to the drawings, A represents the horizontal grain receiving platform, at the front of which the cutting mechanism is located; B, the upright elevator frame, commonly known as the A-frame; O, the seat- 5 supporting plank, and D the drivers seat,

sustained by a standard secured to the plank.

The foregoing parts are of a familiar construction, and are not claimed as of my inven' tion.

In applying my improvement I provide a long arm, E, and insert one end of the same horizontally beneath and against the seatplank, connecting it thereto by a vertical pivotbolt, F, or other suitable pivot, the end of the arm being extended beyond the pivotin order to bear against and receive a firm support from the plank, as shown. The arm thus supported, which is free to swing horizontally in a forward and backward direction, is extended out- Ward and overhangs the grain-platform, and at its outer end is connected by a vertical pivot,

G, to the middle of a horizontal bar, H, of a length substantially equal to that of the plat form. This bar is provided at its ends with rigid depending arms I. To the bar and its arm I secure the upper edge and the end of a canvas sheet, J, which is stretched tightly thereon, its lower edge standing slightly above the surface of the platform. The bar H, its arm, and the canvas constitute jointly the wind-board. To the seat-plank I secure a bracket, K, and to this bracket, by a horizontal pivot, L, I attach a hand-lever, M, the upper end of which stands in proper position to be grasped by the operator while in his seat. I 7 connect this lever at its lower end by a link,

N, to one of the arms of the wind'board, and I also connect it at a higher point by a pitman,

O, to the swinging arm E.

The parts are so constructed and arranged that on moving the hand-lever the pitman O will swing the arm E on its pivot F, and thus carry the wind-board to the front or rear, while at the same time the link N will act to maiutain the board in a position parallel or substantially parallel with the cutter-bar. Thus it will be seen the swinging arm E is employed to adjust the wind-board without causing the board to assume an oblique position.

The hand-lever is provided with a latch, P, 0 arranged to enter perforations in the bracket for the purpose of locking the board in the required position. It is manifest that any other equivalent form of locking device may be employed; and it is also manifest that in place of 5 the supporting-frame provided with canvas a wooden shield or board may be employed.

Having thus described my invention, what I claim is In combination with a harvester, a hori- 10o zontally-swinging arm overhanging the grain- In testimony whereof I hereunto set my hand platform, a wind-board connected to said arm this 7th day of March, 1887, in the presence to by a vertical pivot, and a hand-lever mounted of two attesting witnesses.

on afixed support and connected by links to the windboard and to the swinging arm, whereby HENRY CASE said lever is enabled to move the board for- Witnesses:

ward and backward, and also to maintain its T. M. OSBORNE, parallelism with the finger-bar. J FRANK DAVIS.
