AUTOMATIC BAND-CUTTER AND FEEDER.

SPEGIFICATION forming part of Letters Patent No. 647,733, dated April 17, 1900.

' Application filed July 22 1399.

To a whom it may concern:

Be it known that I, JESSE H. WARD, a citizen of the United States, residing at Newton, in the county of Jasper and State of Iowa, have invented a new and useful Automatic Band-Gutter and Feeder, of which'thefollowing is a specification.

My object is to provide an improved automatic band-cutter and feeder for grain threshing and separating machines, and my invention consists in the arrangement and combination of an endless sheaf-carrier, an endless cutter-carrier, vibrating grain-carriers, and speedgoverning mechanism, and a frame adapted to be connected with a thresher to cooperate the band-cutting mechanism with the cylinder of the machine, as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 is an enlarged longitudinal sectional view showing the relative positions of the sheaf-carrier, the cutter-carrier,and the vibratory grain-carrier. Fig. 2 is a detail View showing a piece of the endless canvas fixed to the cross-bars that connect the endless chains of the cutter-carrier. view showing how motion is simultaneously communicated to the two endless carriers and the vibrating carriers by means of a belt extended from apulley on the end of the shaft of a thresher-cylinder. Fig. 4 is an enlarged View of the speed-governing mechanism on a rotatable shaft, and Fig. 5 is a sectional View of the same mechanism. Fig. 6 is an inside face view of the wheel, that has a variable speed relative to the driving-shaft, as required to slow and stop the motion of the sheaf-carrier. Fig. 7 is a perspective view of one of the vibratory grain carriers connected with the crank of a rotatable shaft. Fig. 8 is a transverse view through the central portion of the machine, showing the relative positions of the shaft upon which the speed-governing mechanism is mounted, shafts that operate the cutter-carrier, the shaft at the innerend of the sheaf-carrier, and the crank-shaft to which the shakers are connected, as shown in Fig.7. The letter A designates the frame upon which the operative mechanisms are mounted.

A is an extension of the frame A for sup- Fig. 3 is an outside side 7 Serial No. 724,769. (No model.)

porting the endless sheaf-carrier B. The inner end of the solid bottom A upon which the carrier B moves, is inclined downward to project over the ends of the vibratory graincarriers, as shown in Fig. 1.

B is the cutter-carrier in an arched position'over the inner end portion of the sheafcarrier B. It is composed of parallel endless chains connected by means of cross-bars B in which are fixed cutters B. An endless canvas 0 is fixed on the inside of the crossbars B to prevent straw from getting into the endless cutter-carrier.

Rotatable shafts O and 0 mounted in the end portions of the frame A, have fixed mating sprocket-wheels C at their ends, upon which the chains of the carrier 13 are supported and operated.

Reciprocating and mating grain-carriers D are connected with the cranks'of a shaft D located below the downwardly-inclined inner end of the sheaf-carrier B. Strips of toothed sheet metal f arefixed on the tops of the grain-carriers D, as shown in Fig. 7, or in any suitable way to aid in advancing straws that fall thereon toward the threshing-cylinder.

- H is the driving-shaft, on the outer end of which is fixed a band-wheel H that is designed to be connected with a pulley or small band wheel on the end of the cylinder-shaft of a threshing-machine in such a manner that it will rotate at a slowerspeed than the cylinder. V

H is a sprocket-wheel on the shaft H, and H is a mating wheel on the outer end of the shaft 0 and H is a chain on said mating wheels, by which motion is communicated from the driving-shaft H to the shaft 0 as required to operate the. endless cutter-carrier B on the mating sprocket-wheels O J and J 2 are idler-wheels that support the cutter-carrier B in an arched position over the inner end of the sheaf-carrier B, and J 3 is an idler-wheel that supports the endless carrier B under the apex of the double-inclined bottom A of the sheaf-carrier B, as shown in Fig. 1.

K is a pawl-carrier in the form of a disk that has afiange K at its circumference and is keyed on the shaft H, as shown in Figs 4:.

Pawls Z are pivoted to theface of the disk in such a manner that their free ends are swung outward by centrifugal force. m, fixed to the disk and the pawlsl, as shown in Fig. 6, in their normal condition retain the pawls stationary, but yield to the centrifugal force to which the pawls becom'ejsubje'ct at times. H Y 7 N is a sleeve-placed loosely on the shaft H. It has an integral band-Wheel N at one end and a disk N at its other that extends within the circumferential flange K of the pawlcarrier K, as shownin Fig. 5. Pins 0 project from the face of the disk N to engage the free endsof the pawls l.

N is a twisted band on the wheel N and a band-wheel on the shaft r, by which motion is communicated to the sheaf-carrier B by means of the sprocket-wheels on the shaft 1'.

r is a sprocket-wheel on the end of the crankshaft D and 'r is a chain on the wheels and D that connects the end shafts, as shown in Fig; 3.

' 7'' represents sprocket-wheels on the shaft r and engage the chainsof the sheaf-carrier B, and W represents idler-wheels on which the chains of the sheaf-carrier are supported. The crank-shaft D is connected with the shaft 0 by means of a chain D on the wheels r and r", as shown in Fig. 3.

In the practical operation of 'my invention whencombined with a thresher sheaves of bound grain thrown on the endle's .sheafcarrier will be advanced toward the cylinder under the endless cutter=carrier and their bands severed. The cutter-carrier being arched over the inner end portion and apex of the sheaf-carrier aids in advancing the straw over the apex of the sheaf-carrier and upon the reciprocatingv carrier at the same time that it cuts the bands, and the automatic mechanism, combined with the driving;shaft of the band-cutter and connected with the sheaf-carrier, regulates the speed of the sheafcarrier as required to prevent clogging. Grain that may be loosened from the straw will fall from the sheaf-carrier upon the vibrating grain-carriers that extend from under the sheaf-carrier to the cylinder.

too rapidly, the advance of the straw will be checked by the automatic governing device'sin communicated, by'means of the band-wheels and band Nfl to the shaft 1' and sheaf-carrier B; but when the straw is advanced to the cylinder so rapidly-as to diminish the speed of the cylinder and shaft H the centrifugal force of the pawl-carrier is reduced, and the force of the springs m will restore the pawls Z' to their normal positions, and thereby disengage the pins 0 as required to stop the ino- Wire springs I Toprevent clogging and choking by advancing the straw tion of the band-wheel N the shaft r, and the sheaf-carrier B until the cylinder recovers' its proper speed again and the pawls Zon the carrier K are again thrown into engagement with the pins 0 by a centrifugal force that overcomes the force of the springs m.

Having thus described the'construction and functions of the various operative elements, the practical operation and utility of my invention will be obvious to persons familiar with the art' to which it pertains; and

fWhat I therefore cla m as new, and desire to secure by Letters Patent therefor, is- 1 In a band-cutter and feeder an endless cutter-carrier consisting of two mating chains, cross-pieces fixed to. the chains and cutters fixed to the cross-pieces, mounted on sprocketwheels that engage the chains and idlers that retain the carrier in an arched position, an endless sheaf-carrier thathas an apex under the arch of the cutter-carrier and a reciprocat ing carrier under the inner and downwardlyinclined end portions of the cutter-carrier and sheaf-carrier, arranged and combined, as shown and described for the purposes stated.
