resume AND BAND-CUTTING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 720,846, dated February 17, 1903. Application filed April 30, 1902- Serial No. 105,258 (No model.)

1'0 all whom, it may concern:

Be it known that I, FREDERICK S- RICH, a citizen of the United States, residing at Mar,- ion, in the county of Marion and State of Ohio, have invented a new and useful improvement in Feeding and Band-Cutting Mechanism, of which the following is-a specification.

My invention relates particularly to feeding and band-cutting mechanism for threshing-machines employing a sheaf-conveyer and means for automatically regulating the speed of said conveyor.

My primary object is to provide feeding and band-cutting mechanism of improved general construction, particular attention being paid to the centrifugal governor by means of which the sheaf-conveyor is initially started after thethreshing-cylinder has attained a predetermined speed, the construction of the friction-clutch operated by tripping mechanism extending into the path of the grain being fed to the machine, the construction of the band-cutting mechanism, the construction of the sheaf-conveyor frame, and the ad- 3' ustment of the rotary band-cutter employed.

In the preferred construction there are employed a sheaf-conveyor frame, an endless sheaf conveyer having a rearwardly and downwardly inclined rear portion, a vertically-adjustable rotary band'cutter located in front of the ridge of the sheaf-conveyor, a series of combined band-cutters and feeding devices moving in cycles above the rear portion of the sheaf-conveyor, belt connection between the threshing-cylinder and the rotary band-cutter, a quadruple-crank shaft for operating the combined band-cutting and feeding devices above mentioned, a centrifugal governor controlling the transmission of motion from the rotary band-cutter shaft to said crank-shaft, a suitably-journaled pinion operated from said crank-shaft and serving to actuate a gear journaled on the drivingshaft of the endless conveyor, and a frictionclutch coiiperating with said gear and controlled by tripping mechanism extending to the path of the grain carried by the conveyer and operating when moved by a surplus of grain to lessen the speed of. or stop the conveyor.

My invention is illustrated in its preferred embodiment in the accompanying drawings,

in which- Figure 1 represents a view of the righthand side of feeding and bandcutling mechanism attached to the front end of a threshing-machine; Fig. 2, a view of the left side of the same Fig. 3, a vertical longitudinal section of the same; Fig. 4, a broken view in side elevation, illustrating means for adjusting the hearings of the rotary band-cutter; Fig. 5, a perspective view of the same parts separated; Fig. 6, a view similar to Fig. 1, but showing the conveyer-frame folded; Fig. 7, a broken perspective view showing the hinges of'the conveyor-frame; Fig. 8, a section taken as indicated atline 8 of Fig. 7; Fig. 9, an enlarged broken section taken as indicated at line 9 of Fig. 2 and showing the trip-controlled friction-clutch; Fig. 10, aview in side elevation, showing a portion of the trip mechanism; Fig. 11, a perspective view of a rock-shaft and rock-arm employed in connection with the trip mechanism; Fig. 12, an enlarged broken section taken as indicated at line 12 of Fig. 2 and showing the governor connected with the rotary band-cutter shaft; Figs. 13 and 14, sections taken as indicated at the corresponding lines of Fig. 12, and Fig. 15 a broken section at line 15 of Fig. 13.

The plates D are provided with forwardly projecting threaded studs a, and the brackets D are provided with vertical slots aiwhich receive said studs,

the brackets D being slidably held in place by nuts a Said brackets D are provided at their lower ends with outwardly-projecting studs a with which the upper ends of the links D pivotally connect. The brackets D are provided with forwardly-projecting fixed points a and forwardly-projecting curved arms a, carrying adjustable points a The bearings D for the shaft D are secured by the points a a as shown in Fig. 4. The frame B is equipped with a toothed segment I), Fig. 1, with which the lever D is connected. It readily will be understood that by this arrangement the brackets 1) may be readily adjusted vertically. The section B of the conveyer-frame has side members I), Fig. 7, pivotally connected at b with the lower corners of the frame-section B. The members b have shoulders 5 which engage corresponding shoulders of the frame-section B and prevent the section B from swinging below a given point. The rear upper corners of the members I) are cut away at b to permit the section B to be swung upwardly somewhat, as indicated in Fig. 6. Connected with the members b by means of bolt-andspring connection 19 are yielding members I), having outwardly-inclined flanges 19 which project normally, Fig.8, over the upper edges of the members 12'. Connected with the rear vertical edges of the sides of the frame-section B are members 5 which flare forwardly and outwardly, as shown. The lower portions of the members 6 embrace the upper edges of the members If, so that when the frame-section B is swung upwardly the members b are pressed inwardly, the yielding connections described permitting this movement. The frame-section B has side members 1) b corresponding with the members b b. The members 1) are equipped with hinge members b, and the members I) are equipped with hinge members b, said members b b being connected by horizontal pivots Z7 The members b 6 are provided with lugs in vertical alinement with each other and having perforations substantially perpendicular to the direction of the conveyor-frame, said perforations serving to receive springheld lockingpins I), having normally forwardly-turned ends 11 The members I) are equipped with lugs 19 which serve to hold the pins Z9 retracted when said pins are drawn downwardly and turned through an angle of one hundred and eighty degrees, so as to occupy the position of the dotted lines in Fig. 7.

The construction of the so-called speedgovernor or centrifugal-conveyer starter D is shown in detail in Figs. 12 to l4,inclusive. It comprises a pulley d, journaled on the shaft D adjacent to the corresponding bearing D Fig. 12, a sleeve (1, fixed to rotate with the shaft D and provided at its inner end with a head or flange al a friction member d slidably mounted on the sleeve (1 and provided with slots (1 an inturned flange d having a female cone friction-surface (Z and provided, further, with angular perforations al which receive lugs d with which the outer surface of the head 01 is equipped, levers 61 provided with books or inturned points d engaging the inner surface of the head (1 and pivotally supported on the member 01 at points d, weights (Z connected with the outer ends of the levers d springs d seated in sockets d of the member (Z and passing through perforations (Z of the member d and tension-adjusting screws al connected with lugs d on the hub of the member (1 As shown, the pulley d has an outwardly-projecting flange d1 provided with a conical surface which coacts with the conical surface of the friction member d It will be understood that when the parts are in their assembled position motion can be communicated from the shaft D through the member 61 to the member d \Vhen the member (1 acquires a given speed, the weights are thrown outwardly, thereby forcing the member 01 inwardly and frictionally connecting it with the pulley d. After the pulley d is set in motion it serves to communicate motion to the shaft E, operating the combined band-cutting and feeding deviccsE The devices E comprise levers e, pivoted on the cranks of the shaft E, which are four in number, forwardly and upwardly curved arms 6, connected with the lower ends of the arms 6, serrated knives e carried by the arms 6, and links e connecting the upper ends of the levers c with the upper portion of the baffle-plate I. The direction of rotation is such as to give to the knives a downward, rearward, upward, and forward motion, each knife of a given set following a different path or cycle, as is evident. Located between the members E 'are rearwardly-curved guards c ,attached at their upper ends to the top of the frame-section B.

The rock-shaft F may be equipped with any number of trip-arms F, it being practically essential, however, that there be one of said arms on each side of the divider-board B The arms have rearwardly-curved lower extremities f, located directly above the ridge of the conveyor, as shown in Fig. 3. shown in Figs. 10 and 11, the lever F has a free arm f, provided with a perforation f which receives the upper extremity of the rod F Above the arm f the rod F is equipped with a nutf and a springf, afiording an adjustable tensioning device.

The shaft C is equipped, Fig. 9, with a collar h, which confines the gear H against movement in one direction, so that when the spring H acts unrestrainedly it forces the conical friction member H into engagement with the corresponding friction surface with which the gear H is provided, so that motion can be transmitted from the gear H through the member H to the shaft C It will be understood from Fig. 3 that when the trip-arms F are pressed rearwardly by an excess of grain the arm f, Fig. 2, is swung upwardly,thereby elevating the rod F and actuating the bellcrank H Fig. 9, in a direction to disengage the member H from the gear H.

The operation will be readily understood from the foregoing detailed description: Motion is transmitted from the pulley A of the threshing-cylinder to the shaft D by means of the belt D \Vhen the threshing-cylinder attains the requisite speed, the shaft D is driven at a sufficient speed to cause the centrifugal governor to act, thereby setting the pulley d in motion and starting the shaft E and the shaft 0 Thus the conveyor 0 is set in motion, andwhen the bundles of grain are placed thereon they are carried beneath the rotating knives D and up over the ridge of the conveyor at (3 where they are engaged by the combined cutting and feeding knives of the devices E which coact with the rear portion of the conveyor and the reciprocating feed-pan A to feed the grain to the cylinder A. ridge at C the arms F are moved, thereby rocking the shaft F and relieving the frictional contact between the gear H and the member H, thereby reducing the speed of the shaft 0 or in an emergency stopping said shaft. The bathe-plates I I act to prevent the straw from crowding up in above the cylinder, and the pi votally-supported baffle-plate 1 allows a certain yielding and prevents aircurrents from the cylinder from interfering with the feeding.

When desired, the divider-board B may be disconnected from the clip B and swung upwardly to the position indicated in Fig. 6. The locking-pins b may be moved to disconnect the upper portions of the hinge members I) from the corresponding portions of the hinge members Z1 after which the carrierframe may be flexedby lifting upwardly at the pivots 17 thus permitting the section B to be swung under the section B, as shown in Fig. 6, where it is secured by chains It, as shown. From Fig. 6 it will be observed that after the conveyer-frame is folded the rods B act in lines falling'in the rear of the pivots Z7 During the operation of folding the members b of the frame-section B yield, as explained, by reason of their engagement with the oblique surfaces of the members 13 It will be obvious to those skilled in the art that many changes in details of construction within the spirit of my invention may be made.v Hence no undue limitation should be understood from the foregoing detailed description.
