To all whom it'may concern: I

Bait known that I, ALFRED STEWART, a citizen of 2 the United States, lresidin'g at i The same reference characters indicate the Sed'alia, in the county of Doug as and State I same parts in all the views.

Let thenumeral 5 designate onevofthe ground wheels of the 'machine. ground wheel is not shownsince such illnstration is not necessary in order to bring out the novel features or my improvements;

The numeral 6 designates the leftjdivider heard u )on which the conveyer chain 7 is of Colorado, have'invented certamnew and clear, and exact description'of the invention, suchas will enable others skilled in the art 5' to which it appertains to make and use the mounts The right divider boardS isd same, reference being had to the accompanyvoid of a chain but upon it .is mountedan ing drawings, and to the figures of reference l auxiliary board 9 to whichare secured a marked thereon, which form a part of this number of spring rods 10, whichnormaiiy specification. I project into the space 12 between the two My invention relates to improvements in l divider boards, whereby thestalksof corn corn harvesters, my object being to do away as they pass betwee the two boards, are with one of the top conveyerphains and one forced by the springs 10, against the left of the lower conveyer chains of the machine conveyer chain 7 thus causing the one chain as heretofore constructed. In the placeof when aided by the tension springs ?.O, to the chains which are removed, I provide perform the function of the two chains as what I will term tension means which act heretofore constructed. As shown in the upon the stalks of corn and press them drawing the upper extremity of the board against the conveyer chains on one side, 9 is supported by an upright bar 14 its upthus making the one chain in each instance per extremity being connected with the when used in cooperation with the tension board by depending bolts 15. This board, means, perform the function of both chains however, may as the machine has been heretofore conmanner. As shown in the drawing it forms structed. As shown in the drawing in the a support for the tension springs 10. It is place of the right top chain, I provide a evident that these springs may be supported board equipped with a number of springs, in any suitable manner. The right chain the same being secured to the said board at guard 18, is devoid of a chain. Its inner one extremity their opposite extremities proedge, however, is reinforced as shown at 17, whereby the stalks of corn as they pass between the guards l6 and 18, are forced by the member 17, against the conveyer chain 19, thus causing the one chain toperform the function originally performed by two, thus greatly cheapening the construction of the machine. I

From the foregoing description the use and operation of the machine so far as my improvements are concerned will be readily understood. When the machine is in use, it is drawn by a team of horses and is in position to straddle a row of corn, whereby the stalks are caused to pass between the upper divider boards 7 and 8 nd the lower chain guards 16 and 18.

Heretofore there have been two to con vcyer chains mounted upon the ivider boards and two lower conveyer chains mounted upon the chain guards l6 and 18. The function of these chams, is to hold the corn in the upright position during the cutting act; In myimprovement I do awe y with one of the upper and one of the lower V'KlBZ' boards, whereby the stalks of corn are pressed against the left top chain. In the case of the lower chain, I reinforce the inner i edge of the right chain guard, whereby the stalks of corn are pressed inwardly against the left lower chain thus making it perform the function ofthe two chains.

Having briefly outlined my improved con struction, I will proceed to describe the same in detail reference being made to the accompanying drawing in which is illustrated an embodiment thereof. 5

In this drawing, Figure 1 a perspective view of a corn harvester equipped with my improvements. in this view only one of the ground wheels is shown. Fig. 2 is a top plan view in detail of the zipper board In this view the eft conveyer chain and its operating devices are indicated in dotted lines. Fig.3 is a to view of the right lower chain guard whicii is indicated in dotted lines, the reinforced part, however, bcing shown in :ull iincs.

The other be supported in any suitable chains as heretofore explained, and as the stalks of corn are passed between the divider boards and the lower chain guards the springs 10 1n one instance and the rein orccment 17 in the other instance, force the stalks oi. corn against the conveyer chains thus causing the one chain above and one chain below to perform the function heretofore performed by two;

' Having thus described my invention, What I claim is:

1. In a corn harvester, the combination with the top divider boards, and a conveyer chain mounted upon one'of the said boards,

a series of tension. elements mounted on they other board and each projecting between. the

twoboards and opposite the chain mounted on the other board, the said-elements being' of elements mounted on the other board and each projecting between the two boards and opposite the chain mounted on the other board, the said elements being-arranged one in front of another and serving to hold the stalks in operative relation with the con- I veyer chain, substantially as described.

3. In a corn harvester, the combination with upper divider boards, lower chain guards, a conveyor mounted on one. of the divider boards and another conveyer mount-- ed on one of the chain guards, of a chainless divider board, a series of tension elements mounted on the chainless divider board and projecting into the space between the two boards, a. chainless lower guard, and an element mounted on the chainless lower guard and projecting into the space between the two guards.

- in testimony whereof I aiiix my signature 1 in presence of two witnesses.

' ALFRED STEWART.
