To @ZZ whom it may, concern,.-

machine, the hand-rake being in position for` sweeping grain from the platform. Fig. 2 isl a perspective view, on a larger scale, of a por tion of the machine, the hand-rake being in y position to make a return movement, it having passed over the platform and swept thegrain therefrom. Fig. 3 is a section through the support of the pitman-gearing and ofthe fingerbeam. Fig. 4 is a plan of the cam-track, illustrating the relation sustained by the friction-roller `of the angular rake-arm `at different stages ofthe raking` operation. Fig. 5 is a vertical section ofthe cani-track, showing the operationlof the yielding gate which controls the positionof the rake at the completion of the stroke over theplatform. Figs. 6 and 7 are other details of the machine.

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

My invention relates, first, to a combination and arrangement of parts whereby the inner shoe acts as a brace to the finger-beam, and themeshing of the pitman-gearing is 4mmaintained, while the outer end of the finger-beam A has freedom of motion up and down, and when necessary both the inner and outer ends of the finger-beam y maybe adjusted together, either higher or lower, the whole arrangement giving increased compactness and convenience` and the several parts mutually aiding to supi port one another.

`SecondVit also relates to certain details of this combination. i y e Third,it relatesto an improved construction of automatic hand-rake, the novel parts of which being the undulating groove or camtrack with yielding gate, theguiding-standard, the crane, the angular rake-arm, and th esc in` combination with the rake and drivers seat and ngerbeam. Fourth, it relates to a novel construction andarrangement of adjustable pole-plate.

| 'Io enable others skilled in the art to make and use my invention, I will proceed to describe the same with' reference to the drawings.

rlhe machine is` made with two large wheels, A B, each on its'own axle a a. The drivewheel A isupon .the left-hand side of the machine, and the supporting-wheel B, which is of sniallerdiameter and hung lower, is on the right handI thereof about three feet. Both these wheels are surrounded by a strong frame, C D, on which the gearing and also the axles of the wheels and the drivers seat D are mounted. Internal cog-teeth, b, are provided in the drive-wheel, and into the same a pinion, E, meshes, the line-shaft F of this pinion ex* tending across the front end of the machine on top ofthe frame OD, and carrying on its e other end a bevel-pinion, G, which meshes into a bevel-piniomH, of the pitman-gear .I

`K. The line-shaft F is supported by two boxes, c d, one on the front rail of the frame and the other on the side rail thereof.

The forward railIof the frame is extended about one foot beyond the inner side rail, as `at e, with a short arm, f, extending back, forming a hinging support, as at g, for one of the forks, h, of a strong hanger, I, said hanger supporting the pitman-gear H .I K and the ngerbeam L. The other fork, h', of this hanger is braced upon a tubular extension, i, of the box c, upon which it playsloosely. These two forks thus hinged have their axes of motion in line with the line-shaft F. The hanger I may be made of cast metal, and should havea partitioned recess or depression, I', in its rear lower part, forth'e reception of the inner end of the iingerbeam L and the crank K ofthe pitman, the latter being crooked and fastened by a hinge-joint, M, onthe brackets ofthe hanger, and then shaped so `as to run upon the ground 4when the machine is used for mowing.

At the rear terminus ofthe hanger I a curved extension-bracket, I27 rises, and terminates in a flat flange, I, which runs at right angl es to the front side of thebracket-F Ainto a curved,

slotted, and perforated guide-standard, O, as

represented. A pin, Z, is used toconnect the bracket of the hanger and the guide-standard together. The guidestandard O is bolted rmi ly to the frame C I), as indicated at k. From the shoe Pat the heel of the finger-beam there is extended upward and inclining inward a strong brace-shield, P', which is hinged upon the hanger I, so as to have its axis of motion in line with the hinge-joint M of the fingerbeam and concentric with the pitman-shaft J.

By means of the hinge M the outer end of the finger-beam has freedom of motion to accommodate 'itself to the surface of thel ground, and-by means of the two/ j oints, g and M, with their auxiliaries, the finger-beam with cutting apparatus may be raised at both ends, and held in a convenient position for transportation or for cuttinghigh above ground, the adjustment not interfering with the motion of the fingerbeam on its hinge M; and as the two hinges are respectively in line with the pitman-sha'ft J and the line-shaft' F, the gearing will always be in a position to operate the knives at any elevation of thefinger-beam. The pinion H,

moving with the hanger I in the path of a ver-L tical circle, rises on the bevel-wheel G, but never changes its gearing relation.

It will be seen from Eig. 3 the shield P of shoe Pis hinged to atubular extension, m, of the box a, through which the shaft J plays freely, and therefore neither it nor the'hanger I, with pitman-gear, can be affected by any elevation or depression ofthe finger-beam L on either of tlie hinges M and g, the whole moving' together on the axis which is in line with the shaft F; hence the working of the gearing will always be free and perfect if in order.

In order to regulate the draft of the machine, a pole-plate, N, which is constructed with an open slot, o, on its under side, is tted around the front rail of the frame C D, and held there by means of a separate plate, p, and two screws applied against the under side of the front rail of the frame. rIhis pole-plate N has a circular hole, o,'and an oblong hole, 02, through it, to

receive' the fastening-bolts of the pole. rIhe oblong hole allows a vertical adjustment of the pole, while the construction of IJthe plate as a Whole admits, by simply loosening the screws, of a lat-eral adjustment thereof to the right or left, so as to bring the pole in the center of l The machine thus far described is adapted for mowing, and for the adaptation of the same to reaping and discharging the grain in bund les suitable for gavels upon the ground at right angles to the path of the horses, I elevate the cutting apparatus by the means and as above described, and attach a platform, Q, to the lback side of the finger-beam, lto receive the cut grain, and an automatic handrake, to be operated by the driver of the machine .from his seat.

The rake attachment consists of an angular standard, R R R2, a crane-like jointed arm, U V, cam-track W t t t2, a supporting or regulating stale, Y, a pivoted rake, X, and hand-lever Z, all supported upon the finger-- beam L, and located in close proximity to the drivers seat D, and nearly over the inner front corner of the platform. The standard R It R'Z is bolted upon the finger-beam L, near the heel of the cutters. The angle or elbow It', which is about twelve inches from the bottom, enables me to locate the rake attachment far enough back to obviate interference with the reel, and also to be convenient to the driv ers seat, and at the same time it enables me to have the whole supported by thefingerbeam. which is essential, in order that the whole may be adjusted together and ,by the one set of means, whenever an adjustment is necessary to cut higher or lower, and inthe adjusting the respective parts will conform to the motions of one another. 'I he inclined eye R2 of the standard receives the stale Y through it, and serves to support the stale, while it allows the same freedom to` change its bear ing as the rake rises and falls and swings back and. forth over the platform. The jointed crane-like arm U V is hung in bearings NV NV of the standard, so as to swing loosely, and it extends downward and over the platform Q., and attaches to the rake X by a pivot, w, as rcpresented. The part U of this arm has its joint q in a slot, r, of the swiveling part V, so that the part U may rise and fall a short distance. Immediately below the point where the cranelike arm is hinged or jointed a short vertical extension, s, running down at right angles to the crane-like arm, is formed on the part U. On the lower end of this extension, which is cylindric, a vertical roller, s', is fixed so asto revolve. The bcari ng W, arranged below this roller, extends out at right angles to the upright standard R R R2 in the form of a triangle, or thereabout, and has a cam groove or track on its upper side, which is formed by :means of the outer segment-mil, t, theinner wave-like rail, t, and the spring-gateflikc section of rail I2, as represented in Figs. 2, 4, and 5. y

The roller s', above described, extends down below therai'ls into the canrtrack, and moves between them when the rake is operated to remove the grain from the platform, but out,-` side of the outer rail whenv the rake is returning for a new sweep, or to" remove a fresh quantity of grain. As soon as the rake has completed its stroke from front to inner side of platform, the small spring-gate through which the roller s2 passes is pressed open by the roller, as indicated in' Fig. 4 by dotted lines, and as soon as the roller escapes out of the groove and beyond the gate, the gate is closed against a projection by the spring t3, so as to prevent the return of the roller on the same line. The eraneflike arm, with rake attached, is operated by the hand-lever Z, bolted to a bracket, w, of the part V of said arm.1

The cam-track is of such construction, as represented in the drawings, that as the roller passes from the point shown .in full black lines, Fig. 4, to the position shown in` dotted black lines, the elbow of the crane-like arm will be caused to rise from lthe vertical position in which it has `been moving (from the point indicated Vby full blue lines) to the oblique position shown in Fig. 2. l This change is necessary in order that the rake-teeth, in

`what he last moved it.

returning, shall clear the grain on the platform. In this elevated position the rake remains until the proper time for again sweeping the platform arrives, when the driver moves the lever Z in a converse direction to Thus :moving the lever causes the roller to return, but on the outer `corner of the segmenterail t, it being impossible, for Want of length in the extension s, for it to standvertical in its return, and therefore it maintains its oblique position, and in turn holds the rake-teeth high enough to enaj` ble them to clear the grain ont-he platform untilthe return-stroke is completedi and it (the' roller) fallsoff of the segmentlrail t and again enters the depressed track. As soon as this occurs the driver pulls in an opposite direction upon the` lever, and thus causes the rake again to sweep off the grain from the platform. rIhe movelnentsofthe rake are repeated from time to' time, as required, to deposit the out gra-in in suitable bundles'.

' `The arrangement described gives great cont rol to the op eratorboth for the removal of heavy grain and speedy performance ofthe same,and, withal, the raking attachment is convenient to the drivers seat, and therefore the raking and driving may be performed by one person.

The bearing WV, with its cam-track, may be i extended and varied, so as to accommodate the motions of the rake to the different sizes and forms of platforms, either for side or rear delivery of the cut grain; and if desirable, under any circumstance, to j convert the attachment into a Wholly mechanical operating device, that may be effected by attaching a pulley and suitable gearing to the main shaft ofthe drive-Wheel and connecting the same with the lever Z 5 but such change will hardly be desirable, as the hand operation gives full control of the rake in reaping thick and thin grown Wheat.
