BAN D-CUTTl-:R AND FEED-ER.

SPECIFICATON forming part of Letters Patent No. 625,010, dated May 16, 1899. Application filed Aprilfl, 1898. Serial No. 678,011. (No model.)

To @ZZ whom, it may concern:

Be it known that I, JOHN HENRY YOUNG, a

citizen ofthe United States, residing at Kingsers; and Ido declare the following to be a.

full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.

The invention has relation to an improved band cutter and feeder for threshing machines; and the object is to improve the construction shown in Letters Patent No. 582,712, granted to me on May 18, 1897 whereby after the tie of the bundle is severed and the bundle spread in an even mass this mass will be conducted direct tothethreshing-cylinder in a smootheven layer.

' Vith this object in View the invention convsists in certain features of construction and combination of parts, which will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of my improved band-cutter and feeder, looking from the rear toward the forward end thereof. Fig. 2 is a top plan view. Fig. 3 is a longitudinal sectional view showing the upper and lower couveyer of the cylinder-feed in operative position. Fig. 4 is a similar view showing the upper conveyer of the cylinder-feed elevated and the lower conveyer of the cylinder-feed swung down and back in order to repair or clean the parts as well as to make room for the repair of the threshing-cylinder. Fig. 5 is a longitudinal sectional view through the crank-pin and the universal coupling. Fig. 6 is a vertical sectional view through the journal-box of the cutter-shaft. Fig. 7 is a detailperspective Fig. 8 is a similar view of one of the saddle-boxes. Fig. 9 is a cross-sectional view taken through the rear end of the'machine, the divide-board, and feed-boards. Fig. 10 is a detail perspective view of one of the roller-su pportin g bars. Fig. 11 is a longitudinal sectional view. Fig. 12 is a detail perspective view of one of the bars that support the lower conveyer of the cylinder-feed, and Fig. 13 is a detail perspective view of one of the slats of the lower conveyer of the cylinder-feed.

adapted to travel around said rollers and feed the grain from the forward to the rear end of` the machine.

8 denotes a roller journaled to the extreme projecting slightly above the upper edge of the end piece 3. This roller serves to prevent the bundle hanging or rubbing against the upper edge of the end piece 3, and thus materially assists in the feeding of the bundle to the conveyer.

9 denotes the divide-board, the rearend of which is connected to standards 10, that fit in brackets on the outside of the side pieces of the frame, and the forward end of which has a post secured to it and fits in a bracket secured to the end piece 3 of the frame.

11 denotes the cutter-shaft, provided with disk cutters 12. This shaft is journaledin boxes 13, secured to posts' 14, and these boxesl are made adjustable by the bolts 15, so as to raise or lower the edges of the cutting-disks with respect to the bottom of the frame. This shaft has a iiy-wheel 16 on one end and a band-pulley 17l on the other end.

18 denotes guide-wings, which are secured to the side pieces andextend forwardly and outwardly around the standards that support the rear end of the divide-board, thus serving to prevent the grain fed over the inclined feed-tables 19 from hanging or straddling the said standardsin its progress along the bottom of the machine.

20 denotes guide-rods secured to the side pieces of the frame above their upper edges, and 21 denotes rake-heads having a lateral sliding engagement on said rods at right ane gles to the path of movement of the main con veyer. These heads are provided with tines that project downwardlyto a point slightly forward end between the side pieces and above the main conveyer and serve to spread the grain after the band has been-severed by the cutters in anl even mass across the bottom of the machine.

22 denotes bell-crank levers connected to posts 23 and 24, and 25 and 26 denote links connecting the rake-heads to one of the arms of each of the bell-crank levers. 27 denotes a link connecting the other arms of the bellcrank levers, and 28 denotes a pitman connecting one of the arms of the bell-crank lever with the wrist-pin 29 in the crank-wheel- 30, secured to one end vof a iiy-shaft 3l, having at its opposite end a 'Hy-wheel 32. This crank-wheel is provided in its face with apertures 33, arranged at different points from the axis of the wheel, whereby the wrist-pin may be adjusted so as to vary the amount of throw of the pitman. The pitman has a universal connection with the wrist-pin by a coupling 34, which receives a ball 35 of the wrist-pin and forms a ball-and-socket joint. The'extreme outer end of the wrist-pin is preferably squared, so as to permit of its being removed from the crank-wheel by a wrench, the other end of the pin being screw-threaded to engage the screw-threaded holes in the crank-wheel. One end of the rear roller that supports the main conveyer is extended and is provided with a d rive-pulley 36, which may be geared with any movable part of the threshing-machine. 37 denotes a pulley fixed to said shaft and connected with a pulley on the end of the cutter-shaft by a crossed belt 38 and `by which the cutter-disks are rotated. Depending from the rear ends of the side pieces of the frame are wings or extensions 39, between which are journaled rollers 40, thatsupport the endless conveyer 41, which is the lower conveyer of the cylinder-feed. This conveyer-il is provided with slats 42, .having on their forward edges metallic strips 43, the upper edges of which project slightly above the 4upper surfaces of the slats, and are preferably formed with saw-teeth 44. These rollers 40 are journaled between the downwardly-depending wings in a novel manner, which I will now proceed to describe.

45 denotes a bar having at its rear end apertures, in which are fitted journals 50 of the rear roller, and having at its forward end apertures 5l, in which are fitted journals 52 of the forward roller.

53 denotes a lever having intermediate its endsan aperture 54, in which are fitted journals of the forward roller, and having its forward end-pivoted to astud 55 and held in place bya nut 56.

57 denotes an inclined slot formed on the lower edge of the wings and terminating iu an oblique bearing-slot 58.

59 denotes a set-screw that works through ahole 60 in the rear end of the pivotedlever and into a hole 6l in the bar. When it is desired to lower or swing the conveyer down for any purpose, these screws are removed and the outer ends of the lever swung downward.

This movement will draw the axis of the rear roller of the conveyer forwardly to disengage it from its bearing-slot and allow it to drop from the inclined slot, as shown in the drawings. In elevating the belt on the conveyer into position the axis of the roller is raised up into the inclined slot, and when it comes opposite the bearing-slot the rear end of the lever is elevated, thus causing the bar to be forced longitudinally, and thereby moving the axis of the roller into the bearing-slots in the wings. The screws are now screwed home, and the rollers of the lower conveyer of the cylinder-feed are securely held in position.

62 denotes a pan arranged below the lower conveyer of the cylinder-feed. The forward end of this pan is pivoted upon a rod 62', and the rear end is provided with a board 63, that is adapted to project under the edge of the feed-table 64 of the threshing-machine and abut against a shoulder 65. This pan is held in this position by a removable rod 66, fitted in eyes 67, secured to the under edges of the win gs. 68 denotes slot-coverers that are adapted to cover the inclined slots formed in said win gs. Thesecoverers have laterally-projecting arms 69, formed with slots 70, and bolts 7l are employed for vadjusting these coverers to the sides of the wings opposite the slots.

72 denotes the upperconveyer of the cylinder-feed. This conveyer' consists of the endless belts 73, connected together by slats 74.

75 denotes bars secured to the side pieces of the frame,and are provided at their lower ends with segmental slots 76 and at their upper ends with adjustable boxes 77. The boxes 77 support a shaft 7S, provided with rollers 7 9, around which the belts pass, and the curved slots receive the journals 8O of a roller 8l, around which the belt also passes. The jonrnals4 80 of the rollers Sl have removable saddie-boxes Sl', connected by coiled springs S2 to the wings of theframes. These springs tend to draw the rear end of the upper conveyer downward and hold it in contact with the grain.

The shaft 7S is provided with a sprocketwheel 83, that is geared with the sprocketchain 84', and a chain-tightener 84 is arrangedv below the sprocket-wheel and is journaled by a stud secured to an adjustable-bracket 85. This bracket may be shifted and held in adj usted position by a set-screw 86, so that the chain may at all times be adjusted to compensate for wear.

87 denotes a sprocket-wheel on the end of the roller 8, and 88 denotes a similar sprocketwheel on the end of the roller 6. A chain 89 connects these two sprockets and imparts the motion of the roller 6 to the roller 8.

The direction of movement of the revolving parts of the machine is indicated by the several arrows, and a detail description of the operation, it is thought, will not be necessary.

In operation the bundles of grain are fed to the forward end of the main conveyer over the end piece 3 and the roller 8, which serves IOO IIO

to assist in holding the bundle onto the conveyer. As the bundle is drawn rearward by the conveyer its band is severed by the rotary knives, and the grain in this condition is then presented to the rake-times, which, moving transversely across the path of travel of the conveyer, evenly spread and distribute the grain upon said conveyer. In this condition the grain is delivered to the conveyers constituting the thresher-feed, andin order to conduct the grain direct to the cylinder in its spread condition is the object of this cylinder-feed. The grain falls upon the lower conveyer and is fed between the diverging rear ends of said conveyers direct to the mouth of the threshing-cylinder. The upper conveyer of the cylinder-feed, owing to its spring action,will prevent the clogging of the grain and the consequent stopping of the machine.

I-Iaving thus described my invention, what ceive the journals of the forward roller of the lower conveyer, a bar having at its forward end bearing apertures to receive said journals, and having at its rear end bearing-apertures to receive the journals of the rear roller of said lower conveyer, and means for locking the bar to the lever, substantially as set forth;

2. In a band-cutter and feeder, the combination with the main frame having at its rear end two depending` wings provided with slots projecting upward from their lower edge and terminating in bearing-slots arranged at an angle to the first-named slots, a lever having one end pivoted to stud-shafts and having interlnediate its ends bearing-apertures to re-
