HARVESTER'.

SPECIFICATION forming part of Letters Patent No. 261,367, dated July 18, 1882.

I Application filed February 17, 1882. (No model.)

To all whom it may concern:

' 7 Be it known that I, SAMUEL D. MADDIN, a citizen of the United States, and a resident of St. Paul, in the county of Ramsey and, State of Minnesota, have invented certain new and useful Improvements inHarvesters, of which the following is a specification.

My invention consists of certain improvements in harvesters, fully described hereinafter, whereby the efficiency of the same is increased.

In the drawings, Figure 1 is a perspective view, showing mainly the construction of the frames. Fig. 2 is a transverse sectional elevation of the machine. Fig. 3 is a detached view of one of the bearing-bars. Fig. 4 is a' detached section through the cutter-bar. Fi g. 5 is a plan,the binder-platform removed. Fig. 6 is an elevation in section of the drivingwheel and adjuncts. Fig. 7 is a perspective view, showing the cutter-driving appliances.

Fig. Sis a diagram illustrating the connection of the driving-shafts, belts, cutter-bar, and elevators. Fig. 9 is a detached perspective view of the butt-board.

The main frame A consists of the back bar, a, and the bars a a M, at right angles to the back bar, and socketed at their forward ends for the passage of the front bar, b, which may height.

be solid orhollow, and on which also swings the frame B, consisting of a back bar, 1), parallel to' the bar If, connecting-bars I) b the side bar, I), and arched frames 11 b, connected to the side bar, I), and to the bar b as shown. Both frames are made of connected tubes, which secures strength with light weight, and the bar 11 may turn with the frame B or independently thereof. The main frame has a fixed axle for the side wheel, 0, and bearings on the bars a o for the axle c of the drivin g-wheel c. The main frame A carries the drivers seat A, and is supported at a uniform distance from the ground by the wheels 0 c. The frame B, with the extension-frames b b b, which support the binder appliances, swings on or with the barb", and the latter, with the cutters 01-, may be turned so as to bring the cutters to any desired angle to the ground to cut at any The tilting ofthe frame B is effected by the driver through the medium of suitable appliances-for instance, a lever, 1 hung to the bar a, and extending beneath the rear bar of the frame B, as shown.

The'grain-divider G is pivoted to the end of the bar b by the extension of thelatter through a hole in the divider, whichis connected bya yoke, 3, to the frame B, so as to move with the latter. The bar b is the cutter-supporting bar, and a bent strip, D, attached thereto by bolts 6 forms at the rear a flange, e, and at the front a support, 6, for the cutters and guards. At theend of the bar b is an arm, I)", connected by a rod, b to a lever, b, by means of which the operator can turn the bar to alter the angle of the cutters to the ground. The bar b may, however, be clamped so as to move temporarily with the frame B, or an arm from the bar 11 may extend to and be connected permanently to the frame A, so that the motion of the frame B will not alter the angle of the cutters.

The frame B has bearings for two shafts,ff,

driven faster or slower than thebelt, so as tocarry the butts of the grain faster or slower than the stalks, to bring the whole into proper position in the canvas to deliver it properly to the elevator. Endless chains it pass round pulleys on shafts k 70 against which the grain is' pressed by a presser-plate, E, hung to a bar, 1, which may be turned by the operator to raise or lower the plate, the lower end of which is curved to permit the grain to pass between it and the elevator-chains and condense and pack it against the latter, the body of the'plate holding the grain until it passes to the horizontal platform F of the binder.

As the binding devices constitute the subject of a separate application for Letters Patcut, I will not describe them here.

The means by which the movements are imparted to the belts, sprocket-chain, carriers, elevator, as wellas to the cutters, will be best understood by the diagram Fig. 8.

The driving-wheel shaft 0 carries a pulley, c, from which a chain passes round a pulley, d, turning freely on the bar b and with miterteeth engaging with those of a miter-pinion, (1 on a shaft, 01 Abelt passes round pulleys m mone on the shaft 01 and the other on the shaft f-and another belt, it, passes round a pulley, n, on the shaft 76 and a pulley, n, on the shaft f.

It will be seen that the belt or canvas h de rives its motion from the driving-wheel a through the shaft of the latter, and the pulleys, wheels, and shafts c d d d m mf and roller 9, in the order named. The sprocketchain derives its motion from one or other shaft, ff, according as the pulley i or i is clutched to its shaft, each pulley having a clutch-section, 8 which engages with a clutchseetion, s, sliding on the shaft, according to the position of a 1 -lever, s pivoted back of the bar If. This lever s is moved from the drivers seat by a lever, s. The pulleyt' is larger than the roller 9 and pulley i, so that when the pulley i is clutched to the shaft the chain travels faster than the belt, but when the pulley i is clutched to its shaft the chain is driven slower than the belt.

The cutter-bar G is driven from a rock-shaft, H, the arm 1) at the forward end of which, or a cross-bar thereof, enters between two upright studs, q g, on the knife-bar, allowing plenty of play, so that the tilting of the cutterbar b or of the frame B does not interfere with the free communication of the motion. I have found this connection to be a most effective one, as there is no strain of the parts, friction is reduced to a minimum, and all jerking is prevented.

The shaft H has at the rear another arm,p, that is connected by a pitman to a wrist -pin on a crank-wheel on the end of a shaft, 19

driven from the main shaft 0 by miter-wheels It will be obvious that other gears and devices may be used for moving the different parts without departing from the main features of my invention.

The belt h is protected by a guard-plate, h, below it, and from the rear edge of the belt extends the grain-platform 7L2, hinged at its front edge, so that it may be set at any desired angle to throw the grain forward or permit its being thrown back to bring it in proper position for the band and elevator to operate thereon without moving the binder appliances. The elevation of the platform It is effected by the operator by means of a bar, h.

The guard 6, being a little higher than the sprocket-chain, serves to protect the latter, as

also to enable the reel to bend back the grain properly.

As the binder-frame, elevator, grain -platform, and frame B swing round a common center, 1), and as the pulley d, from which the other movements are imparted, is on this center, the chan ge in position of the frame B does not slacken or tighten the driving-belts,chains, or cables, and all driving parts are maintained in proper relative position.

0 Figs. 2 and 9, is a butt-board secured to rods '6 connected and sliding in part of the frame, and provided with nuts, so that the divider may be set forward or back to any position required to guide the grain into proper relation to the elevators.

In order to maintain the rigidity of the frame, as well as take up any slack from loosening of the joints, I combine with the frame at any desired points a bent or double anglebrace, 8, supported centrally by an upright or bearing-for instance, the box-and extended at the ends to the sides of the frame through eyes, and provided with tightening-nuts, as shown in Fig. 3.

By the combination of the rectangular main frame and the arched frames 1/ b all in one structure I secure great strength and rigidity with comparative lightness.

I have shown and described levers for adjusting the different movable parts from the drivers seat. It will be apparent that other devices may be used for this purpose.
