IMPROVEMENT IN RK'ES FOR REAPING-MACHIINES.

Speciflcation forming part of Letters Patent No. 13,596, dated September 25, 1855 reissue No. 2,641 dates June 11, 1 867.

To all whom it may concern:

Be it known that THOMAS N. LUPToN,of Winchester, in the county of Frederick and State of Virginia, did invent certainnew and useful Improvements in Automatic Rakes for Harvesting and Reaping Machines; and that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in whic Figure l shows a platform or framing, a b c, to which are attached the automatic devices, composed of a vertical crank, e e, with tubular collar ff, spur-wheels and drivers, and bevel-.gearing g, h, i, j, k, a, m, and p,- and a revolving sleeve, L, and revolving piston-rod m; the'slide-socket q q and reciprocatingarm r'r; the pitman u; crank-connecting rod .9 s the horizontal rake w w. Fig. 2, slotted slidmg arm fr r.

The improvement consists in arranging an automatic discharging-rake, in a harvester,

with a straightl finger-beam, so that the rake shall pursue a path parallel, or nearly so, to the finger-beam, and to the inner and outer side of the platform, entering on the side next tothe standing grain, following it to the front, thence across the platform parallel, or

nearly so, to the finger-beam, and then along the side opposite to the first, discharging the grain, and, finally, along the rear ofthe platform to the place of starting.

To enableothers skilled in the art to construct this rake, the invention is described as follows:

`A crank, e e, is formed of desired diameter and length, and arranged to, and supported vertically by, cross-pieces b1 b2 d. The upper part of this vertical crank works through a collar, ff. The upper part of this collar ff is attached to a gear-wheel, h, workin g above the cross-piece d1 d2. At the upper extremity of the crank-shaft is a small spur-wheel, g, working in a driving-gear, k, having its axleshaft extending ,through the cross-piecesd d downward to the lower cross-pieces d1 d2, and

at the lower end of this axle or shaft is attached a small gear, j, working in another of the same diameter, as seen at h. Underneath the crosspiece d1 d2, and attached thereto, is

a small inverted bevel-wheel, I.. The collar ff is attached permanently to a baseplate or bevel-washer, c, corresponding to the bevel of the fixed-gear I. This collar and base-work around the crank-shaft, and are attached permanently to a horizontally-working slide-socket, g q, of suitable size and length. This slidesocket is formed of a strip of thin plate or sheet metal, `with turned or fianged edges,

thus forming agrooveor slide-plate, within which is tted a reciprocating or sliding arm, W r, having an oblong opening or slot, Fig. 2, formed in it, sufficiently wide to admit the crank-shaft or spindle to pass through it, as well as long enough to afford the desired play backward and forward. To the slidesocket g q, at'its forward end, is attached a little col- 'larstandard,'o o, which holds or supports a rod, m, having on its out end a small bevel.

gear wheel, n. This revolving pistonrod is supported by a collar-standard, y, attached to supported by a collar-standard, 1, attached to the reciprocating arm r r, to the under side of which arm is attached a crank-rod or pitman, s s. This pitman is attached to the arm by a screw or rivet joint, e. At the end of the reciprocating arm T 7', and working pendently therefrom, is a small rod or shaft, t, passing upward sufficiently through the arm r r to admit of having a small bevel-cog wheel, p, attached to its end, and of the same size as the bevel-gear n. To the lower extremity of this pendent rod or shaft t is attached permanently a horizontal rake, ww. The whole of the within-described devices being shown complete in Fig. 1.

-In forming this improved automatic rake,

which can be most readily attached to, or

connected with, the framing or platform of an ordinary reaping or harvesting machine without requiring any very materia-l alteration of the general mechanical construction of the original machine, the operation of the said rake is as follows Motion is communicated to the gear-wheel lc by any band and pulley arrangement or gear-work connected ,with the general mechanism of the machine; and the .gearwheel k, working/inthe spur-wheel g, attached to the crank e e, gives motion to the said crank e e, while the spur j, being attached to the same common axle of the gear-wheel k, works in the other spur-wheel h, attached to the collar ff, which collar extends downward,and is attached to the slide-socket q qby the basewasher c. It will be observed that the crank revolves independently of the wheel h, which moves the slide-socket; thus, the crank rotates, and the slide-socket revolves aroundthe crank. This crank'is connected with the slidesocket through means of the 'pitman orv connecting-rod s s, connected to the reciprocating arm r r by a pivot or screw-joint, z. As the crank rotates, the slide-socket q q is carried around, and in this movement the revolving sleeve-socket Lis also carried around, and at the same time is revolved by the bevel-gear n', working in the `stationary or fixed bevel-gear The revolving piston-rod m, as it moves around with the sliding arm r lr, also plays in and out, and as its end bevel-gear u actuates the bevel-gearp, attached to the rod t, the rake fw w is caused to maintain a parallel position relative to the sides of the machine and the grain-platform and while the slide-socket q q describes a true circle, the slotted sliding arm fr r and the revolving reciprocating piston-rod m both play in and out simultaneously, havin ga compound motion, and while rotating on their axis revolve or move horizontally, and describe a serpentine circuit, by which arrangement the rake w 'w is made to pursue a path parallel, or nearly so, to the linger-beam, and

to the inner and outer side of the platform, entering on the side next to the standing grain, following it to the front, thence across the platform parallel, or nearly so, to the fingerbeam, and then along the inner side of the platform, discharging the grain, if desired, in bundles at the' side of the machine, or on a receivingplatform, if desired.

i The foregoing is a full and accurate description of the construction and operation of said automatic rake; and, being well aware that cranks, pitmen, rods, and gear devices have the platform, and then returning to the place of beginning, continuously. y

2. An automatic rake, in combination with an elongated arm or shaft for carrying or driving it.

3.' An automatic continuously-rotating rake on a vertical axis mounted on the platform, in combination with a straight linger-beam.

4. Attaching the rake-head to an extensible arm in such manner as to allow the rake-head to follow the contour 'of the platform in its ro- Y tation.
