ATENT POUGHKEEPSIE, NEW YORK, ASSIGNOR TO HIMSELF IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 11,040, dated December 22, 1863.

To all whomjt may concern: Be it knJwn that I, STEPHEN HULL, of Poughkeepsie, in the county of Dutchess and State of New York, have invented certain new and-useful Improvements in Reaping and Mowing-Machines; andI do hereby declare that the following is a full, clear, and exact description thereof, reference being had. to the accompanying drawings, making a part of this specification, in which- Figure 1 1S a top view of my improved machine. Fig. 2 is a sectional view-of Fig. 1,

showing the raising and lowering devicefor the frame of the machine. Fig. 3 is atop view of the improved tooth, detached from the machine. Fig. 4 is a longitudinal vertical section through Fig. 3. Fig. 5 is a perspective view of the removable cutting-plate for the tooth. Fig. 6, Sheet 2, is a vertical longitudinal section, showing the reel and spring divider. Fig.7, Sheet 2, is a front view of the machine complete.

Similar letters of reference indicate corresponding parts in the several figures.

To enable others skilled in the art to make and use my invention, I will proceed to de scr'ibeits construction and operation.

In the accompanying drawings, A A represent two longitudinal bars, and B atransverse bar, while 0 is a curved bar, all of which are suitably bolted together, so as to form the frame of the machine for containing and sup porting the cutting apparatus, the machinery which gives motion to the cutters, the reel, and

the drivers seat. The front bar, B, which is at rightangles to the parallel bars A A, is depressed or inclined downward, and receives on its'end a bearing for the gudgeon ot' a curved hinged beam, B, and the curved bar 0 extends downward in the same plane as bar B, and forward a suliicient distance to receive on its end the opposite end or gudgeon of the hinged beam B. This beam B is thus supported by the frame of the machine, of which it .i'orms a part, and the curved bar 0 forms within or between it and the inner bar A a convenient space for the interposition of a small supporting-wheel, O, the axle of which being suitably affixed to the bar 0 this wheel forms the inner support for the frame, while the large driving-wheel D constitutes its outer supby the driver who sits in the seat D port. This frame is suspended beneath the axle of the driving-wheel D, as shown in Figs.

1 and 7 of the drawings,and the driving-Wheel D has an inside-gear wheel, I) scoured toits spokes concentric with its axis, which engages with the teeth of pinion a. This pinion communicates a reciprocating motion of the sickle I) through the medium of bevel spur-wheels a a inclined shaft a crank-wheel a, and connecting-rod c, as shown clearly in Fig. 1.

1) represents a flanged block,which is bolted securely to the inclined portion of the bar B, and between the flanges of this block is pivoted, at c, a draft-pole, E. The rear end of this pole has affixed to it a segment-rack, (I,

.which engages with a toothed pinion, d, that is keyed to a transverse rock-shaft, c.

This shaft 0 has its hearings in the extended portion of block D, and also in .a perpendicular plate,f, and carries on one end a long lever, g, which is in a suitable position to be operated The platefis perforated, as shown in Fig. 2, to receive the tooth g of a spring-lever, 9 which is pivoted to the lever g and extends up in a line with this lever g, so that by grasping the two levers with the hand the tooth 9 may be released from the fixed plate f, and thus released. The driver can rock the pinion d and vibrate the pole E, the outer end of which being attached to the team, this movement of the ,pinion d will raise or depress the front end of the machine. Then,byreleasing the springlever g the tooth g will catch into one of the perforations in platefand establish the parts in their adjusted position. On the outside of platef, and keyed the shaft 0, is a treadle or foot-plate, h, upon which the driver puts his foot, and by means of which he obtains a leverage to assist him in effecting the above-described adjustment of the machine. By these means the front end of the entire machine can be easily and quickly raised or depressed, whether it be 'in operation or at rest.

The hinged beam B is lowered downwardand suitably recessed to receive the fingerbeam F, which is secured to it by bolts or in any other convenient manner. The platform G is secured to this beam F on one side, and the fingers Mare secured to itontheotherside,

in the usual manner. The platform is made I of a quadrangular or polygonal form, as shown in Fig. 1, and upon this platform I arrange a tender, G, which is made up of a number of hinged boards, asrepresented in Figs. 1, 6, and 7. The longitudinal board j of this fender G is secured in a perpendicular position,

back delivery; or any degree of inclinationmay be given to the fender G by simply loosening the screw in plate 70, which attaches the rear end of this fender to its platform G.

In connection with the adjustable fender G I employ a curved strip, H, which is attached securely at its forward pointed end to the outer dividing-shoe, J, and which extends backward, upward, and inward, its rear end. he-

' ing free to vibrate as it is shaken by the motions of the machine, or the outer end of the platform rolling over rough land. This strip H maybe called an auxiliary divider, as it effectually separates the cut grain from that which is standing and prevents the cut grain from falling off the outside edge of the platform beneath this divider. It may also be called a spring-fender," as it is made sufficiently thin to receive a vibratingortrembling motion from the jarring motions of the machine, and thus as the cut grain falls on it it will be thrown oif again toward the center of the platform, and this rebounding of the 'cut grain will prevent it from falling over or behind the fender G.

The divider J, to which the spring-fenderis secured, is bolted to the outer end of the finger-bar F, and, extending back, forms a bearing for the outer supporting-wheel. I, which supports the outer end of the platform and also the cutting apparatus. (Shown in Figs. 1, 6, and 7.)

The reel is also constructed with a view to the proper delivery of thestanding crop to the cutters, and the deposit ofthe cut product upon the platform in such a condition thatit can be readily bound into sheaves. has its hearings in a standard, L, which issesecured to and which projects up from the inclined bar B, and also in a curved support,,L, which is secured to a beam projectingfrom the platform G near its rear end, and projects forward to a suitable point. To the Wings or parallel ribs of the reel I attach curved rods 5 s s, which extend out from their ribs and are curved, as shown in Figs. 1, 6, and 7. One end of each rod 8 is secured at or near theend of a rib, and extends inward or obliquely toward the middle of the opposite rib. The auxiliary rods 8 do not extendfrom rib to rib, still they are bent inward toward the middle of their respective ribs. Thus constructed the The reel-shaft K reel operates with great efficiency in gathering the upper ends of the standing grain together at the same time that the grain is pressed back upon the cutters, and being thus compressed the grain is much more easily cut, after which it fall upon the platform in a compact heap, ready to be bound into sheaves. These reel-gatherers will be found very useful in cutting grain which has been blown down, as the rods 8 s s will lift it up and draw it into the cutters, which will cut'it uniformly. The reel-shaft K carries on one end a grooved pulley, K, over which a band passes, which communicates with a grooved pulley, '1 on the hub of the central supporting-wheel, G, and in this way the wheel 0 acts as the driver for the reel, giving to it a motion toward the cutters, as indicated by the arrows in Fig. 6, Sheet 2. The reel-shaft is allowed to have an endwise play in its bearings for the purpose of allowing the hinged beam B to play freely in its bearings as the outer end of the cutting apparatus rises and falls in accommodating itself to the uneven surface of the field.

In Figs. 3, 4, and 5 I have shown anew mode of securing the plate 2%, upon which the sickles slide, to the finger 2". This plate 15 is formed, as represented in Figs. 3 and 5, with a tenon, r, on one end, on each side of which is a perpendicular projection, 1". The opposite end of this plate, which is made of steel, is formed as shown in Fig. 3, and perforated to receive a pin, to, which .projects up from the lower surface of the slot in the finger.' The finger is suitably recessed to receive the rear end of plate t, and mortised to receive the tongue or tenon r, as shown in Fig. 4. The perpendicular portions 1' press against the lower side of the slot in the finger, and when the plate is thus fitted in its place the end of pin to is hammered down over the plate, thus riveting it rigidly in its seat.

The pivoted plate N (shown in Fig.1) is used to control the extent of vibration of the cutting apparatus, and when this plate is slipped under the notch n, which is made in the hub of the hinged beam B, it prevents the outer end of the cutting apparatus from rising too far. When it is not to be used this plate can he slipped out of the way.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. WVhile not claiming a spring-bar per 86 in combination with the platform of a. harvester, I do claim the spring device H, constructed and applied substantially as shown and described, in combination with the divider J and the platform- G, substantially in the manner and for the purpose desaribed.
