Application filed March 10, Serial 1W0. 51,097.

T 0 all whom it may concern:

Be it known that l, INeoLr BIRKELAND, a citizen of the United States, residing at Fort Benton, in the county of Uhouteau and State of Montana, have invented a new and useful Grain Stacker, of which the following is a specification.

This invention relates to harvesting machines and more particularly to machines known as stackers, of the type adapted to carry and drive a header that cuts and delivers grain to the stacker.

An object of the invention is to provide a stacker which will form. a stack in such a manner that when the same is dropped or deposited on level ground, the material forming the stack will slope from the renter downwardly and outwardly, forming a crown to shed water and permit the grain to cure.

A further object of the invention is to provide an adjustable hinged. bottom designed to discharge a stack in a manner to form variable slopes to the straw forming the stack.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 illustrates a side elevational view of astacker constructed in accordance with the present invention.

Figure 2 is a plan view of the same.

Figure 3 is a rear elevational view; and

Figure 4. is a detail view disclosing the connection between the bottom sections and the Z bars supporting the side walls thereof.

Referring to the drawings in detail, the stacker includes outer frames, one frame being formed of the side members 1- and 5, connected at their forward ends and mounted on a wheeled truck 2, the side members 4 and 5 diverging towards the rear of the machine, so as to permit the header drive wheel 1, associated therewith, to be positioned therebetween at the rear end of the same.

Members 6 and 7, form a part of the other frame which is centrally mounted upon the doors close one end of the stacker, and

supporting wheel 3, and which is constructed in the usual and well known manner. Extending across the front end of the machine and connecting the frames, is the overhead axle member 10 and braces 8 and 9 respectively, which braces are held in position. by means of the truss rod 29.

Connected to member f by the hinges 15,

is the header frame 16 which extends later ally and is supported at the outer end by wheels 17. Bolted to members 5 and 6 are upright 2 bars 12, to which bars are riveted sheet iron plates forming the side walls of the stacker, the plates being indicated by the reference character 12. The front and end walls of the stacker are of like construction, the Z bars being bolted to member Doors 18 are mounted upon the rear Z bars 12 by means of the hinges 38, which the angle the i The doors 31 form the boitom of of drums for operating the same, the

hand wheel. 22 being provided and. adapte'l to cooperate with the pawl 23 to secu e the winding drums against movement. Drums 21 have cables i9 running downwardly and connected to the front ends of the angled bar 32.

Secured to the rear ends of the angle bars 32 are the pulleys 20 which accommodate the cables 19, which pass from the drums the header drive wheel 1 and transmits ion through the chain 26, sprocket wheel 25 and flexible coupling 28,1310 the header shaft 27 that operates a header construction not shown.

in operation, grain is delivered into the stacker by the header or machine associated therewith. the material being?) of. course scattered and tramped down. When sufiicient amount of grain has been deposited in the stacker, the stacker is brought to a standstill, and by means of wheel 22, pawl sprocket 2- 1- is keyed to the ax e of 23, drums 21 and cables 19, and 19, bottom 31 is released, the stack, or the weight of the contents of the stacker forcing the same open, whereupon the stack falls to the ground. I

ihe stacker is now moved ior'wardly, cables 19 having some slack will allow doors 13 to open when the stack contacts therewith. When the machine is clear of the stack, the bottom 31 is reset by means of the hand wheel 22, drums 2i and cables 19,

Due to the normal downward slope of the bottom doors when the stack is being formed, there will be more grain in the center of stack than at the outsides thereof, so that when the stack drops on the ground, the sides otthe stack will settle causing the straw in the stack to slope downward to the edges of the stack forming a crown thereon, thus setting a completed stack, even though the machine is filled to its capacity.

With the invention thus described, what is claimed as new is 1. In a stacker, outer frames, each of said frames comprising spaced walls, a movable bottom, hinged ooors at the rear oi" the stacker, cables secured to the movable bottom and extending in proximity to the hinged doors to normally hold the hinged doors in their closed positions, a wheeled support for the stacker, and means for operating the movable bottom and hinged doors.

2. In a stacker, outer frames, wheeled doors of the bottom in their normal position, said holding means cooperating with the hinged doors at the end of the stacker for normally holding the hinged doors in their closed positions, and means for releasing the said hinged doors to permit the weight of the material positioned in the stacker to move the said inclined doors to their open positions.

3. In a stacker, outer frames, each of the frames comprising inner and outer walls, inclined doors forming the bot-tom of the stacker and having connection with the inner walls, vertical doors hingedly connected to the inner walls, said vertical doors adapted to contact with the inclined doors to restrict movement thereof, securing means having connection with the inclined doors for securing the inclined doors against movement, and said securing means adapted to engage the vertical doors to normally hold the vertical doors in their closed positions.

In testimony that I claim the "foregoing as my own, I have hereto aflixed iny signature in the presence of two witnesses.
