Be it known that I, FREDERICK S. RICH, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented a new and useful improve- 1 l Feer'iing and Band-Cuttin Mechanhich the following is a specification. My invention particularly to feedin band-cutting mechanism provided "1 means for automatically retarding the to prevent clogging or slugging the oer.

nary object is to provide simplified L ed means for preventing clogging ,y nder, an improved speed-governor for three ng the feeding devices into operation after cylinder has reached a predetermined number of revolutions, an improved guard for the rotary band-cutter. and irnprov l means for sustaining the lower run of the endless sheaf conveyer when the frame of the sheaf-conveyer is in the folded position.

in the improved construction i dispense with the trip device which has commonly b .n employed for stopping the operation of ie endless sheaf-conveyer when the con er becomes overcharged. In lieu thereof i provide means dependent upon the resistance encountered by the crank-actuated feed. and cutting devices which. I employ that serve to retard the movement of the endless sheaf-conveyor automatically when the she f-conveyor is overcharged.

My inventionis illustrated in its preferred embodiment in the accompanying drawings,

in which Figure l tional view of feed and band-cutting mechanism equipped with my improvements;

Fig. 1", an enlarged broken sectional view "taken as indicated at line 1 of Fi 1 and b represents a broken side eleva-- view showing the details of the speed-governor employed, the casing-plate appearing in Fig. 1 being removed ;'Fig. 6, a sectional view taken as indicated at line 6 of Fig. Fig. 7, a perspective view of aweight-carrying arm employed in the construction of the speed-governor; Fig. 8, a view of an automatically-controlled friction-clutch forming a part of the power-transmission means between the rotary cutter and the crank-shaft which actuates the oscillating cutting and feeding knives; Fig. 9, a section taken as indicated at line 9 of Fig. 8; Fig. 10, a section taken asv indicated at line 10 of Fig. 1 and showing a detail of the transmission meansbetween thecrank-shaft and the drivingshaft of the endless conveyor, and Fig. 11 a view of an adjustable lever which supports the stub-shaft shown in Fig. 10.

A'description of the preferred construction is as follows:

A represents the fixed portion of the frame of themechanism, the sail'ne being connected with the front end of thethreshing-machinc in the usual manner; B, the folding framev of the endless sheaf-conveyor, this folding frame having a section B connected by a pivot B with the fixed frame in the usual. manner; B an endless sheaf-conveyor passing over suitable pulley-equipped shafts, including shafts B B andB, the latter constituting a driving-shaft for the sheaf-conveyer; O, a threshing-cylinder; D, a rotary band-cutter driven in the usual manner from the cylinder by means of pulley-a'nd-belt connection (not shown) at the farther side of the machine D, a stationary guard for the band cutter; D a shaft for the band-cutter; D, a

speed-governor connected with the shaft 13 E, a crankshaft; E, combination feed and cutting devices operatingabove the grain in a well-known manner; E friction-clutch mechanism connected with the crankeshal't E and actuated from the speed-governor l) by a sprocket-chain E; F, a stub-shaft adjustably connected with an adjustable lever F" and having journalcd thereon a combinatlon sprocket-wheel and spur-gcar F and F a spur-gear secured onthc driving-shaft B of the sheaf-conveyor and meshing with the spur-gear of, the member F.

The endless sheaf-conveyer comprises end-,-

less chains 1), connected by slats 1i, e'qui ed with fingers b The section B of the folding frame' of theconveyer is equipped at each side with hooks of the form shown in Figs. 1 and, 1*, both of said hooks being shown in the drawings. The drawings illustrate the manner in which the hooks support the lower portion of the endless conveyor, while at the same time allowing the conveyor to operate without breakage in case the attendant fails to take the chains ofl the hooks after extending the conveyer-frame. The shanks of the hooks lie outside the chains, and the points of the hooks extend inwardly and toward the front end of the conveyer, the inclined surfaces 6 (shown in Fig. 1) enabling the conveyer to operate without breakage until the rattling attracts the attention of the operator. The endless conveyer has a rearwardly and downwardly inclined rear portion, as is now wellunderstood in the art. To maintain the upper portion of the rear end of the endless conveyer in-proper position, as when,

for instance, the knives E are drawing upon straw which is in engagement with the spines on the slats of the conveyer, I provideon the inner sides of the stationary frame-section A angle-form guides If, one of which is shown in Figs. 2 and 4. v

' The rotary band-cutter is of well-known construction and need not be described in de tail. of the cutter is equipped with suitablyspaced knives.

supporting shoes d Figs" 2, 3, and 4. Each shoe (1 comprises a forwardly and. downwardly inclinedsheet-metal member d having lateral oblique flanges d and an expanding member confined between the flanges d and adjustably connected with the upper plate d by means of bolts (1 The free edges of the flanges d are in more or less intimate contact with the knives of the rotary cutter,

and it will be understood that the flanges may be spread apart to'bring them closer to the knives by adjusting the bolts (1.

The speed-governor D comprises a wheel or pulley d having an outwardly-turned flange (1 a sprocket-wheel d formed in-' tegral with the pulley and receiving the sprocket-chain E a weight-carrying arm or bar d having a hub secured by a set-screw upon the shaft D curved friction-shoes'd, having inturned ends connected by pivots d 'with the extremities of the bar (1 links (1 connected with the free ends of the brakeshoes and extending through guide-lugs d on bar (E weight-arms d supplied with ad justable weights and connected by pivots d with lugs J" on the bars (7, said weight-arms being provided with short arms or lugs 1 bearing upon the free ends of the links d springs 1/", confined between the lugs d and It is suflicientto remarkthat the shaft The guard D comprises a, cross-bar d, from which depend shanks d,'

with thepulley d to fiinclose, the weights an springs; i f The crank-shaft E is eguipped with a plu rality of combination fee mg and cutting de; vices E, which are suitably spaced and which move in cycles in a now well understood manner. y

The frictioneclutch device E? will be understood by reference to' Fig'sfS and 9. It comprises a sprocket-wheel 'e, rotatable with respect to'the crank-shaft E and equipped on its outer surface with lugs e, su porting a .curved rod e'fla bar or membere aving a hub keyed uponT/the: shaftf-E and affording a j journal for the sprocket-wheel e, said meinber 6 being equipped on the'outer surface of one of its extremities witha lug a", through which the rod 6 passes freely; a curved spring 6 encircling the rod 0?, and confined between-an adjusting-nut g on the rode and the lug e of the member a a rooved Wheel.

e journaled on the shaft E and 'avingformed integrally therewith a sprocket-wheel el, and a friction band or strap e assing about the wheel a and having. its en s secured to pins e 6 with which the sprocket-wheel e and the member a are equipped, respectively."

The lever F is joined by a pivot f to one side of the frame A and is curvednear its.

central portion; where it is provided with a slot-7", which 'adjustably receives the stub shaft F. The lever has a handle f and'near thereto is provided with a' perforation which receives a bolt equipped with a winged end.-

7. Said bolt is'adjustable in" a slotf, a

formed in a segmentf connected with the frame A. The member F comprises-a sprocket-wheelf, joined by a sprocket-chain f ,to the sprocket-wheel e onthe shaft E,-

and a s'pur-gearf meshing with the spur-Q gear F on the drive-shaft of the endless con,-

From the foregoing detailed description the operation of the mechanism will be readily understood. The threshing cylinder 0 of the separator is driven inthe usual 'man- D Power is now transmitted through the sprocket-chain E? to the sprocket-wheel r. and the-bar or member 'eiiasdflren througl the medium of the sprocket-wheel 1 and the spring a thereby rotating the erank-slml't E. 1 0

Normally the tension (adjustable) of the spring 1* is such that the friction-strap engages the l'riclion-pulley a with suilicient friction to rotate the same and transmit power to the endless conveyor: 'hen an abnormal amount of grain passes beneath the combination feeding and cutting device-s E, actuated by said crank-shaft, the movement of the crank-shaft is retarded somewhat, while the sprocket-wheel e continues to advance, thereby causing the frictionstrap c to lighten or rel *ase its hold upon the friction-wheel 0, thereby retarding or stopping the movement of the endless conveyer. Meanwhile the devices E continue tooperate and gradually" convey the overplus of grain to the cylinder,-whereupon, the normal condition having been reestablished, the endless conveyer will again be, operated at normal speed. n I

It will be understood that changes in details of construction within the spirit of the invention may be made. Hence no undue limitation should be understood from the foregoing detailed description.
