NVILLIAM N. \VHITELEY, OF SPRINGFIELD, OHIO.

GRAIN-WHEEL ADJUSTER FOR HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 342,663. dated May 25, 1886.

Application filed September 19, 1885. Serial No. 177, 531.

Figure l is a side elevation of my invention. Fig. 2 is a horizontal section of the same.

Heretofore it has been common to mount the grain-wheel upon an arm or bracket pivoted to the frame at the divider side of the machine, so that by adj usting said arm at different points on said frame the machine might be supported at different heights from the ground, and it has been common to provide a lever with segment and latch, whereby said arm might be moved and locked; but, so far as I am aware, said lever has never been flexibly attached, so that when it had served its purpose of changing the position of the frame it might be turned down, protected, and concealed by the divider-board. It has always, I believe, been suffered to project rigidly, and in some positions always exposed to contact with the straw and standing grain, or, after using, entirely removed.

My invention therefore consists in an ad justable grain-wheel arm moving on a fixed segment-plate, with a flexible or pivoted lever to control the same, said lever being capable of being turned down when not in use, concealed, and protected by the divider.

A is the frame of the machine at the divider end. B is the divider-board, and O is the ordinary grain-wheel. D is the segmentplate, bolted rigidly to the frame A or divider B, or both. E is the wheel-arm, pivoted at one end at I) to the segment-plate B. and provided at the other end with a hub, F, for the wheel C.

Movement of the arm E on its pivot I) carries the frame A and divider up or down, according to the direction of that movement, and a spring-impelled locking-bolt, G, will retain it in any desired position. A lever, H, is pivoted to the arm E conveniently by the pivotbolt 1), so that it is capable of a movement entirely independent of the arm E. It will be observed that the weight of the machine is a constant force tending to lower it as to (No model.)

the wheel, so that force from the attendant will always be required in the same direction, either to raise-the machine to a higher level or to control its descent to a lower level. I therefore provide the arm E with a stop-shoulder, 6, against which said lever will strike when raised up, so as to apply the required powerto said arm to raise or lower the ma chine. The lever H is also provided with the ordinary hand-latch to control the lock-bolt G. WVhen the change of position of the frame A has been effected and the arm E locked in its new position, the lever H may recede from contact with the shoulder e, and may fall down by the divider,where it will be out of the way, concealed, and protected. I think it convenient and advisable to make the arm E with a loop, 9, behind which the lever H may pass to its pivot I) and relieve said bolt of all lateral strain from a sidewise pull on the hand end of lever H.

Having described my invention, I claim 1. The stationary segment-plate secured to the divider-board, and an arm pivoted at one end to said plate, provided with means for looking it in position, and carrying thegrain-wheel spindle at its other end, combined with acoutrolling-lever pivoted to said arm and capa-' ble of dropping away from its operative posit-ion to be concealed behind the dividerboard, substantially asset forth.

2. The stationary segment-plate attached to the divider-board of the machine, in combination with the movable arm pivoted thereon, provided on one end with a stop-shoulder and carrying the grain-wheel on the other end, means for locking the arm to the plate in different positions, and a lever pivoted on said arm and adapted to raise or lower said arm and wheel when lifted up to a rigid position against said stop, and free to turn down out of the way of the grain when the arm is locked.

3. The combination of the stationary segment-plate attached to the divider-board of the machine, a movable arm pivoted thereto and carrying on one end thegrain-wheel and a stop on the other, a lifting-lever pivoted to said arm, and having a spring-actuated bolt, and the hand-latch to lock the said lever to the segment-plate, substantially as set forth.
