PLATFORM=FLAG FOR HARVESTERS.

SFECIFICATION forming part of Letters Patent No. 432,766, dated July 22, 1890.

Application filed April25,1890- Sen'al No. 349,421. (No model.)

To ztlZ whom it may concern.-

Be it known that I, HENRY, E.PRIDMORE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illi nois, have invented certain new and useful Improvements in Platform-I lags for Harvesters, of which the following is a specification.

The object of this improvement is the adjustment of the backboard or, as more properly called, the platform-flag toward and from the finger-bar, and the supporting of the flag so that it will not retard the heads of the grain in their passage to the elevators, as will be understood from the following description.

In the drawings, I igure l is a perspective View of a harvester-platform, showing the rear of the divider and grain-wheel as well as the beginning of the elevator and with a flag attached thereto in accordance with my invention. Fig. 2 is a top view of a section of the flag and the brackets which support it, together with the extension-board which fills the space between the rear sill and the platform-canvas. Fig. 3 is a rear View of the same part shown in Fig.2.

Like letters refer to like parts.

A is the divider; B, the grain-wheel; C, the elevator, and D the platform. Bolted to the rear sill E of the platform near its center is a bracket F, standing up from the sill so that the heads may have a passage-Way beneath the flag G, which is supported upon this bracket F by a double-\l-shaped bracket H, Whose arms in the construction that I have shown are united at the top and bolted to the I upper part of the frame of the flag G, and diverge downward and outward from the flag the distance it is desired that the flag shall be moved forward and backward. The arms then bend upon themselves and return parallel to each other to the lower part of the frame-work of the flag and are bolted thereto. The lower parallel arms of the bracket H rest upon and move in ways upon the bracket F,

and are held in the desired position by the clamp I, which is pressed upon the arms by any suitable locking mechanism, as, for in stance, the boltand thumb-nut J.

The upwardly extending arms of the bracket II obviously need not be united, but could be separately bolted to the frame-work of the [lag without departing from my invention.

When the grain is very short, it the adjustment upon the bracket His not sufficient to carry the flag as near to the cutting apparatus as desired, the bracket 'F can be changed from the sill E to the holes Kin the front part of the extension-board L. The adjustment can then be made by the bracket H, as heretofore. Should the platform-canvas be the full depth of the platform, thus dispensing with the extension-board L, the adjustment of the bracket E into the holes K could obviously not be made.

I am aware that flags have been heretofore attached at one end and made adjustable along the seat-plank as well as to and along the divider eross-girt, and that they have been swung forward and backward upon frames and brackets. In the passage of the machine, however, over the rough ground of the farm these plans have subjected the flag to great shaking and strain. By supporting the flag near the center I have been enabled to make its frame-Work lighter and to carry it much more "steadily.

hat I claim is The combination of a harvester-platform and a bracket upstanding therefrom, with a flag to which issecured a rearwardly-extending bracket that rests upon and is adjustable by sliding back and forth on the bracket from the platform, and a locking device to retain the flag in position, substantially as and for the purpose specified.
