To all whom it may concern: 1

Be it known that I, CHARLIE C. PALMER, a citizen of the United States, residing at Osce 01a, in the county of Clark and State of Iowa, have invented new and useful Improvements in Regulating Means for Self-Feeders and Band-Cutters, of which the following is a specification.

This invention relates to improvements in self-feeders and band-cutters for threshingmachines, and refers more particularly to the means employed for regulating the supply of grain delivered to the threshing-cylinder.

Theobject of my invention is to provide a structure whereby the grain-bundles if too freely fed toward the cylinder of the thresher will'automatically control the power-transmitting means, and thereby only permit the passage of a maximum amount of grain.

A further object of my invention is to provide a feed-regulatingmechanism thatinthe event the grain be rapidly fed toward the cylinder to cause the delivery-belt to choke the continued pressure thereon will effect a reversal of said feeding-belt and cause the grain to be entirely removed from theen trance to the carrier leading to the cylinder,

automatically return to its normal movement. In the meantime, however, the motion of the cylinder and itscarrier will notbe afiect'ed;

Many other objects and advantages will be hereinafter referred to and be particularly tion of my improvement, showing its application. Fig. 2 is a perspective view of the grain-admission-regulating device. a top plan View. Fig. 42i$ a detail section on line at 4 of Fig.1. Fig. 5 is a detail section The" same numerals refer to like parts in all the figures.

1 indicates the receiving end of a threshing-machine having the usual cylinder 2 of any well known construction and being mounted on a shaft 3; A frame 4 projects from the thresher andis adapted to carry the mechanism for cutting and feeding the grain to the cylinder, together with the parts 00- whichthe friction-pinion 24 impinges. ,pinion 24 is slidably mounted on a shaft 25 of such shape as will materially decrease the :thrust andreduce the friction of the working parts. The shaft for a portion of its length Fig. 3 is a crank-shaft 13 and the opposite end being guided or supported in suitable ways. The inner end of the feed-carrier is in close proximity to'the cylinder 2, so as to always supply a uniform and constant supply of grain thereto.

Mounted in the frame 4 on a crank-shaft l4 and rocking supports 15 are a series of forks 16', having amotion in a forwardly and downwardly direction and adapted to spread the bundles and assist in feeding the grain to the lower feed-carrier, it being understood any well-known means may be employed to w cut the bundles of grain.

The mechanism thus far described relates more particularly to what is substantially common in the art and only constitutes features with which my invention coacts.

Mounted in bearings 20 on the framed is a shaft 21, carrying a sprocket-wheel 22 and a friction-wheel 23, the latter being beveled out slightlyto form a bearing-surface against The is in cross-section approximatelya Maltese of corresponding size and shape." Toreduce the friction to a minimum,the pinion 24 is provided with an antifriction-rolleri'25 for each wing of the shaft 25, which makes the parts connected to said roll extremely sensitive in operation. On one end of the shaft 25 is fixed a worm 27, meshing with a wormgear 28 on the shaft 6. Hence motion to the extension-belt is imparted from the frictionwheel 23.

On a rocking shaft 29, mountedabove the cross, and the pinion 24. has an opening 26 rear end of the extension carrier, are a series of depending fingers 30, the lower end being of such distance from the belt as will permit the passage of a predetermined amount of grain before they are operated. A crankarm extends from one'end of the shaft 29 and is connected by a link 31 to an upright lever 32, pivoted to the frame at 33 and havsprocket-Wheel 35 on the crank-shaft 14, communicates a direct and constant rotary motion to the friction gear 23 and to the shaft 13 through the medium of the sprocket-wheel 36.

From the foregoing description it is thought the operation of my invention will be readily understood by those skilled in the art to which it appertai-ns. Motion is imparted to the shaft 14 from the wheel 39, imparting a kicking-forward movement of the forks, revolving the friction-gear 23, imparting a forward movement to the lower feed-carrier, revolving the friction-pinioncarrying shaft 25, and the feed extension-belt. The bundles of grain are now delivered to the extension-belt and they are carried up and subjected to the action of the forks 16 to be equally spread over the lower feed-carrier. As before stated, the fingers 30 are of such height from the belt as will only permit a certain amount of grain to pass without imparting a rocking motion to the rock-shaft. Should, however, more grain be delivered to the carrier than can be acted on by the thresher-cylinder, it will force the fingers 80 in and rock the shaft 29, which movement will draw the frictionpinion 24 toward the center of the frictiong'ear 23, which by reason of the extensioncarrier receiving its motion through this pinion the advance movement of the grain will be reduced and accordingly the amount of grain delivered to the lower feed-carrier. If the excess of. grain continues to accumulate in front of the fingers 30, the shaft 29 will continue to rock, whereupon the movement of the friction-pinion 2 4: is continued and will eventually pass to the opposite side of the center of the friction-gear, imparting a reverse motion to said friction-pinion, and necessarily to the extension feed carrier. However, the movements of the forks, friction-gear, and the cylinder are uniformly the same.- The reversing of the belt will naturally unload the grain, and when a sufficient quantity has been removed and the pressure of the grain against the fingers relieved the coacting levers will bring the friction-gear to its normal position and again the feed-belt will feed the grain toward the cylinder. The weight of the fingers 30 and. the cooperating ing-cylinder, a friction-gear, gearing which is constantly in contact with the friction-gear for communicating motion from said frictiongear to the feed-belt, and levers connected to said gearing for communicating motion from the gear to the friction feed-belt, in proximity to the belt'for effecting the reversal of the motion of said belt, when it carries more than a predetermined supply of grain, substantially as described.

A machine for the purpose specified,com-' prising a frame, a feed-belt, a thresher-cylinder, a shaft, a beveled friction-pinion on the shaft adapted to move lengthwise thereon, a beveled friction-gear, a lever located in proximity to said feed-belt, and a second. lever connected to the first-named lever for moving vthe friction-pinion'toward and past the center of the friction-gear, to first stop and then reverse the movement of the feed-belt when the latter carries more than a predetermined supply of grain, substantially as described.
