WILLIAM J. AUMEN, OF ALLENTOWN, PENNSYLVANIA.

GRAIN -HARVE STER.

Specification of Letters Patent.

Patented Jan. '7', 1908.

Application filed November 8, 1907- Serial No. 401,266.

To all whom it may concern:

Be it known that I, WILLIAu J. AUMEN, citizen of the United States, residing at Allentown, in the county of Lehigh and State of Pennsylvania, have invented new and useful Improvements in Grain-Harves ters, of which the following is a specification.

My invention pertains to grain harvesters, and has for its object to provide a grain harvester embodying grain boards in combination with its platform and elevator; the said grain boards being under the control of the driver so that they may be quickly and easily raised and lowered as occasion demands during the progress of the machine, and both boards being arranged to prevent displacement of the grain when the machine is moving up a grade, and the board cornplementary to the elevator being constructed with a view of affording "an unobstructed channel for the upward passage of the heads of both long and short grain and of adjusting said heads and preventing undue rearward movement of the same so as to assure proper supply of the grain, irrespective of its condition, to the table of the machine.

With the foregoing in mind the invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specifica tion,-in which:

Figure 1 is a rear elevation of so much of a grain harvester as is necessary to illustrate the preferred embodiment of my invention the same being shown with both of the grain boards raised. Fig. 2 is an enlarged section taken in a plane through the platform of the machine and looking toward the elevator and showing both grain boards as lowered. Fig. 3 is an enlarged detail section taken in the plane indicated by the line 33 of Fig. 2 and showing the arrangement of the grain board of the elevator, relative to the lower and upper endless aprons of the elevator.

Similar letters designate corresponding arts in all of the views of the drawings, referring to which:

A is the platform of a grain harvester. B is the elevator frame of the harvester. C is the lower apron of the elevator; D, the upper apron of the elevator, and E, the conveyer or apron of the platform. These parts may be of the ordinary construction or of any other construction compatible with the purposes of my invention, and any suitable connections may be employed for driving the aprons or conveyers from one of the ground wheels of the machine. As shown in Figs. 2 and 3, the upper apron l) of the elevator is preferably of a less width than the lower apron C thereof.

F is a grain board hinged to the rear edge of the platform A and arranged to swing vertically, and G is a grain board hinged to the rear edge of the elevator frame B. The grain board G of the elevator is of right angle form in cross-section for an important purpose which will presently be pointed out, and the outer wall a of said board is preferably provided at its lower end with a flared extension I), the office of which is to assist the heads of the grain in entering the channel afforded by the angular grain board. hen the said grain board G and the grain board F are in their raised positions they may be depended on to prevent undue rearward movement of the grain when the machine is being moved up a hill, and it will also be evident that by virtue of its having the outer wall a, the board G will serve the purpose stated when in its lower position. When the board G and the board F are in their raised positions, the machine is adapted for handling short grain, and it will be manifest that the angular board G will afford a channel up which the heads of the grain may freely pass, and at the same time will adjust the heads so as to prevent choking and so as to assure the passage of the grain in proper position to the table of the machine. Vhen both of the boards F and G- are lowered as shown in Fig. 2, the machine is adapted to handle long grain to advantage, and in this latter position it is clear that the board G will afford a smooth and unobstructed channel up which the heads of the long grain may freely pass, and at the same time will prevent undue rearward movement of the heads and by adjusting the same'i. 0., keeping the heads in the proper course, will assure the passage of grain in proper position to the table of the machine.

It frequently occurs that short grain and long grain will be found at different points in a field, and it is therefore advantageous for the driver of the machine to be able to quickly raise and lower the grain boards F of the and G without stopping the machine. For this reason I provide the mechanism best shown in Fig. 2 through the medium of which the driver .may expeditiously and easily raise and lower the boards F and G and adjustably fix the same. The said mechanism comprises a hand lever H, fulcrumed at c on the main frame of the machine and equipped with a spring-pressed detent (Z, a segmental rack 1 fixed onthe machine and arranged when engaged by the detent to adjustably fiX the lever. H and the parts connected therewith, a rock-shaft J, journaled in a bearing a on the frame and having arms f and g the latter of which is provided with an angularly disposed portion h disposed and movable ina slotted bracket i on the back of the grain board F, a. link K interposed betweenand connecting the arm rock-shaft J and the upper arm of the hand lever H, and a link L extending between and suitably connected to the outer wall a of the grain board G and the lower arm of the hand lever H. The upper arm of the hand lever H is arranged within convenient reach of'the driver on the seat M. of the machine, and by virtue of the connections described in the foregoing it will be readily understood that when the detent d is disengaged from the rack 1, and the upper arm of the lever H is thrown toward the right in Fig. 2, the grain boards F and G .will be raised to their closed positions, in

which positions they may be adjustably fixed by the driver permitting the detent d to ref-Engage the rack I. Then when the upper arm of the lever H is at the right, and it 'is desired to lower the grain boards F and G,

the same may be accomplished by the driver disengaging the detent (Z from the rack 1 and throwing the upperarm of the lever H toward the left and then, permitting the detent to reengage the rack. It will also be understood that through the medium of the lever H, the connections described, and the cooperating segmental rack and detent, the

grain boardsF and G may be conveniently placed and adjustably fixed in positions intermediate their fully closed positions and their fully open positions as the condition of the grain being harvested demands.

It will be gathered from the foregoing that while materially increasing the efficiency of a grain harvester, my improvements do not materially increase the cost of a harvester and do not add in an appreciable degree to the weight of the machine.

The construction herein illustrated and described constitute the best practical embodiment of my invention of which I am cognizant, but it is obvious that in the future practice of the inventionsuch changes or modifications may be made as fairly fall within the scope of my invention as defined in the claims appended.
