JOHN SMALLEY, OF BOUND BROOK, NEW JERSEY.

IM PROVEM-ENT IN HARVESTERS.

Specification forming part of Letters Patent No. 23,618, dated April 12, 1859.

To all whom it may concern Be it known that I, JOHN SMALLEY, of Bound Brook, in the State of New Jersey, have made certain Improvements in Reaping and Mowing Machines; and I do hereby declare that following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A is the driving-wheel, which supports the main frame W W of the machine. The cogwheel B is attached to the driving-wheel A and takes into pinion O, thus transmitting mo. tion to bevel-wheel E, which is attached to the shaft D of the pinion. This sbaftDis provided with two collars, JJ. The neck Ifitsloosely between these collars. The bottom edges ot'neck I rest upon the sides of groove Hin the standard J', (see Figure 6,which represents across-Seaton through the neck and groove,) so as to be free to slide back and forth, and thus move the shaftD in the direction ot' its axis either way without straining it orimpedin g its revolution,while the lower part of the groove El contains thelubrieating material. This side motion of the shaft D can be produced by means of the slot c in the end of lever d taking hold of a pin projecting from the top of the neck I. This lever is pivoted at c, and is provided with a handle at its rear end, which rests upon a standard and plays between two projections, t' z', of said standard. (See Fig. 2.) A pin, f, and two holes, g hf, serve to retain the lever in any of itsextremepositions. Theobjectofthislateral adjustability of the shaft D, produced by means of lever d, neck I, and collars J J, as described, l

is to bring the bevel-wheel E into or out of gear with bevel-gear F, according as it may be desired to work the cutting apparatus or not. When the two bevel-wheels are in gear the shaft G transmits motion to the disk K, which latter, by means of a crank-pin, L, gives a reciprocating motion to the rod N and cutterbar O,tl1e lower end of rod N being pivoted to the inner end of thecutter-bar. This end of the cutter-bar is bent forward to where the rod N is jointed to it for the purpose that this joint may be sufficiently far in front of the piece T not to come in contact with it, so as to allow the front surface, a, of the piece T to be straight, thus affording ample bearing-sun,

face for the straight portion ot' the end of the cutter-bar. The piece T, to which the ngerbar l? is screwed, can be adjusted in the slotin the -piece U, projecting from the main frame of the machine. The line in which the piece T can be moved in said slot is oblique, as will be seen from Fig. l of the drawings, and is at right angles to the axis ot' disk K, so that the piece T may be adjusted in the slot to any desired height withoutrfstraiuing the joint of rod N. The length of thgrod N can be adjusted so as to suit the adjustment of the piece T by means of socket M, into which its end screws.

The cnlters R are provided with small openings S below the cutter-bar,which, in combination with the enlargement Q of the fingers, serve to work out ine grass, 85o., which is apt to gather between the lingers Q and the bottom'surface of the cutters in rear of their cutting-edges.

The divider d is screwed to the outer end of the finger-bar P, as seen at Fig. 1, which represen ts the machine when arranged for mowing. A piece, c', is screwed or bolted to the divider, and is made witlltwo or more sockets for the support of clearin garnis a. b. These sockets are arranged nearly in the same vertical plane. The piece c is also provided with a hub, 3, in which is a hole, c, for the reception and support of a caster-wheel when the machine is to be moved from field to lield. It has also an extension, x", by which it is fastened to thefmger-bar Pand divider d by means of the bolts m' m. By reference to Fig. l it will be seen that piece c answers a threefold purposenviz., first-,a ri gid support to the trackclearing arms; second, a support to a casterwheel when the machine is to be moved from eld to lield after it has been adjusted for mowing, and, lastly, a means of bracing the divider, so as to render it less liable to get out of its true relative position as respects the linger-bar I than would be the case if the piece c were notI provided with the projection w.

The piece f' with a shield, g', for keeping the grain or grass from entangling with the cutterbarjoint, is screwed to the piece 'I. It is also fastened to frame W by means of rod V for the purpose of bracing the piece T more effectually. The rod V is jointed to the front end of the piece f', and the front end of the rod is screw-threaded, so as to adapt the rod V to the adjustments ot' the piece T in the slot U. The piece to which the front end of the rod V is screwed is attached to the frame W by and turns around the bolt z".

When the machine is to be used for reaping the platform h', Fig. 3, is attached to the machine by passing bolts through the corresponding holes n' n' a' and e' e' e', and fastening bolts l' l' in the holes m' m after the piece c' has been removed..

When the machine is to be transported from field to field a caster-wheel is attached to the outer end of the iingerfbar by passing Athe shank ofthe caster-wheel through the hole in ,the piece c'. A similar caster-wheel, o', is attached to the dividing-board k' of the platform h' by passing its shank through the hole in the piece p', screwed to the board k', and preventing it from dropping out by means of a pin, q'. Another caster-wheel, s', ofthe same construction is attached to the rear corner of the machine, as seen in Fig. 2.

A Two seats, Y and Z, are connected by a frame, b b, aud rest upon elliptical springs X X, X' X', so as to ease and balance the seals. Y is the drivers seat when using themachine tor reaping. The rakers scat Z can be turned on a pivot, a, so as to accommodate the raker in his operations. When mowing the driver takes the seat Z, so as to add his weight toward throwing the machine backward.

The frame i@ u is pivoted to the outer ends of the shaft ot' the driving-wheel A. This allows the frame and the reel attached toit to be swung more or less toward the cutting apparatus, and to betxed in any desired position by means of slotted arcs 7c k, one on each side ot' theframe W W', and set-screws m, Without altering the distance between the driving-pulley I and the reel-shaft pulley q. When mowing the whole weight of the reel and reel-frameis thrown back as far as the slotted arcs allow. Aside from this adjustment, however, the reel can be placed higher or lower by bolting the reel-shaft bearings u v to any of the holes t. Une of these bearings, o, is open, so as to allow ihe'shaft to be raised and withdrawn wheneve it is desired. to remove the reel.

The reel consists of horizontal blades z, attached to vertical arms x and to oblique arms y, which arms are fastened to a metallic connection or hub, w, upon the end of the reelshaft 10.

Fig. 5 represents the draft-pole, to be fastened to the machine by the bolt Ir".

The metallic hub w is of peculiar construction, so as to receive the arms, as fully shown in the drawings. This hub w is usually made of cast-iron, and is so formed that the arms x are supported at right angles to the reel-shaft p, in sockets 'i i i z', entirely open on one side, while the arms y are supported in similar sockets, 2 2 2 2, in an oblique position, with their ends meeting and abutting against each other in front ot' the end ot' the reel-shaft, as shown in Fig. 1. By adopting the form of hub as herein described for supporting the reel-arms it can be conveniently molded and cast, while at the same time lightness and strength is combined.

The track-clearer used for mowing is shown in Fig. 1. It consists of two arms, a' b', extending back and inwardly. These bars extend back in nearly the same vertical plaue until near the end, when the top arm turns in for the purpose of tipping or turning the cut grass in from the standing or uncut grass.

` Having described my improved reaper and mower, what I claim therein as new, and for 'which I desire to secure Letters Patent, is-

1. The combination of the seats Y Z, one of which is movable, as described, with the seatframe b b, elliptical springs X X, X X', and main frame of the machine, the whole being arranged substantially as described andshowu, and for the purposes set forth.

2. Constructing the outer piece, c', in the peculiar manner above described-viz., with two or more sockets, a", in combination with the caster-supporting hub 3 and extensionpiece 90"-for the purposes set forth.

3. The neck I, in combination with collars J J, groove H, standard J', and lever d, arranged substantially as shown and described, for the purpose of throwing the gearing in and out of action, as set forth.

4. Supporting the reel-arms by means ofthe peculiarlyconstructed hub w, as shown and described.
