BAND-CUTTER AND FEEDER.

SPECIFICATION forming part of Letters Patent No. 667,242, dated February 5, 1901.

Application filed May 28, 1900. serial No. 18,217. (No model T0 all whom, it henry concern:

Beit known that LWILLIAM MoRLEY,a citizen of the United States, residing at Fontanelle,in the countyof Adair and State of Iowa, have invented a new and useful Improvement in Autom atie Band-C utters and Feeders, of which the following is a specification.

My improvement relates to the band-cutter and feeder for which United States Letters Patent were granted to me December 29, 1896, No. 573,898, and January 2, 1900, No.640,684; and my invention consists in the construction, arrangement, and combination of elements and subcombinations, as hereinafter set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which- Figure lis aside elevation of my improved machine,in which two disks and a brush-wheel are used for governing the advance of grain to the cylinder of a thresher. Fig. 2 is atop View from which parts are broken away to disclose the band-cutter and other operative mechanism. Fig. 3 is a central longitudinal sectional view showing the relative positions of different parts of the machine. Fig. 4 is a perspective view of a detached portion of the speed-governing mechanism.

The letter A designates the frame ofthe machine, and A2 the driving-shaft, mounted in bearings fixed on the top and end portion of the frame.

B is a band-wheel on the end of the shaft A2, adapted to be connected with the cylinder-shaft of a thresher, as required to transmit power and motion from the thresher to the band-cutter and feeder mechanism. B2 is a band-wheel on the other end of said shaft connected with the pulley C on the end ofthe shaft C2 of the rotary cutter C3 by means of a band C4.

D is a lever pivoted on top of the machine near its apex.

D2 is a rock-shaft in bearings fixed to the parallel sides of the machine, and D2 indicates straight bars fixed to the rock-shaft to extend at right angles therefrom and over the endless carrier B in such a manner that the bars will be raised and lowered alternately by the varying quantities of grain advanced on the carrier, and the rock-shaft actuated by such raising and lowering of said bars.

D4 is an arm on the end of the rock-shaft D2 and connected with the end of the lever D, as required to transmit motion from the rock-shaft to the lever.

F is a rotatable shaft in bearings fixed on top of the machine and in parallel position with the drivin g-shaft A2 and connected with the rotatable shaft F2, that actuates the endless carrier F2 by means of sprocket-wheels and aV chain, as shown in Fig. 2.

H is a disk fixed on the shaft F, and H2 is a mating disk fixed on the driving-shaft A2 in such a manner that the two disks will be in parallel planes.

J is a bracket slidably mounted in bearers J2, fixed on top of the machine to carry a brush-wheel J 2 in right-angled position relative to the rotatable disks.

L is a rod adjustably connected with the end of the leverD and also with lthe bracket H in such a manner that the bracket will be automatically adjusted, as required to change the position of the brush-wheel relative to the two disks F2 and F3 by the actions of the bars D3 and the rock-shaft D2, as required to regulate the speed of the endless sheaf-carrier F3.

It is obvious that when grain is advanced too fast by the carrier F3, and the bars D3 are thereby elevated by the quantity of grain crowded under them the rock-shaft D2 will be actuated, as required to vibrate the lever D and slide the brush-wheel J3 relative to the disks H and H2. Moving the brushwheel toward the circumference of the disk H on the shaft will diminish the speed of the shafts F and F2 and the sheaf-carrier F3 and a reverse motion of the brush-wheel will increase their speed. Itis also obvious by thus moving the brush-wheel in a plane parallel to the two disks and in contact with the faces of the disks the two disks will coact and simultaneously and instantly respond to the movement of the adjustment of the brush wheel relative to the centers of the disks and that a more sensitive governing device is thus prod uced for regulating the speed of the feeder mechanism relative to the speed of the threshing cylinder. A simple automatic mechanism is thus provided for governing the speed of the sheaf-carrier and the feeding of grain regularly to the cylinder of a thresher IOO as required to prevent the annoyances and damages incident to grain being advanced too rapidly to the cylinder of a thresher.

I am aware a brush-wheel has been adjustably connected With a rotatable disk in such a manner that the shaft carrying the brush- Wheel could be adjusted by hand; but in no instance has a brush-Wheel been combined with two rotatable disks and mechanism for automatically adjusting the brush-Wheel in opposite directions relative to the centers of the disks in the manner shown and described to accomplish the purposes contemplated by my invention.

Having described the construction, combination, and arrangement of the different operative elements, the practical utility of my invention will readily be understood by persons familiar with the art to which it appertains, and

What I claim as new, and desire to secure by Letters Patent, is-

A band-cutter and feeder comprising a frame, an endless sheaf-carrier in the frame, a rock-shaft having fixed bars extending over said sheaf-carrier and an arm at one end, a rotary cutter mounted above the said rockshaft and connected with a driving-shaft, a

driving-shaft adapted to be connected with the cylinder-shaft of a thresher, a lever pivoted on top of the machine and connected with the arm of said rock-shaft, a rotary shaft in bearings fixed to the top of the machine and in parallel position' With the drivingshaft, a disk fixed to the driving-shaft, a disk lixed to said parallel shaft, a brush-Wheel mounted on a bracket slidably connected with the machine and in contact with the faces of the two disks, a rod adjustably connected With said bracket and said lever to move the bracket and brush-Wheel ina plane parallel to the faces of the two mating disks, a band-Wheel on the end of the driving-shaft and a fixed pulley on the shaft of the rotary band-cutter, a sprocket-wheel on the end of the shaft mounted on top of the machine and connected with a sprocket-Wheel on the end of lhe shaft of the endless sheafcarrier and a chain on said sprocket-wheels, allarranged and combined to operate in the manner set forth for the purposes stated.

WILLIAM MORLEY.
