' UNITED STATES PATENT -OFFICE SAMUEL JOHNSTON, OF SYYRAOUSE. NEW YORK.

IMPROVEMENT IIN HARVESTERS'.

Speciication forming part of-Letters Patent No. 36,843, dated November 4, 1862; reissue No. 3,267, dated January 19, 1869.

To all whom it may concern:

Be it known that I, SAMUEL JOHNSTON, of Syracuse, New York, late of the city of Buffalo, in the county of Erie and State of New York, have invented a new and useful Uombined Harvesting-Machine; and I do hereby declare that the following is a full, clear, and exact description of the same',"reference being had to the accompanying drawings, forming part of this specification, in which* Figure l' is a perspective View of the whole machine, the hand-rake heilig in position for sweeping grain from the platform. Fig. 2 is a perspectiveview, on a larger scale, of a portion of the machine, the hand-rake being in position to make areturn movement, it having passed over the platform and swept the grain therefrom. Fig. 3 is a section Lthrough the support of the pitman-gearing and of the finger-beam. Fig. 4 is a plan of the camtrack, illustrating the relation sustained by the friction-rollerl of the angular rake-arm at ditferent stages of the raking-operation. Fig. 5 is a vertical section of the cam-track, showing the operation of the yielding gate which controls the position ot' the rake at the completion ofthe stroke over the platform. Figs. 6 and 7 are other details of the machine.

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

My invention relates, first, to a combination and arrangement of parts whereby the inner shoe acts as a brace to the finger-beam, and

the meshing of the pitman gearing is main-` tained, while the outer end of the finger-beam has freedom of motion up and down, and, when necessary, both the inner and outer ends of the finger beam may be adjusted together either higher or lower, the Whole arrangement gi\;ing increased compactness and conveniences, and the several parts mutually aiding to support one another; second, it also relates to certain details of this combination; third, it relates to an improved construction of automatic handrake, the novel partsrof which being the undulating groove or cam-track with yielding gate, the guiding-standard, the crane, the Vangular rake-arm, and these in combination with the rakeand drivers seat and finger-beam; fourth, it relates to a novel conlng the the right hand thereof, about three feet.` Boththese Wheels are surrounded by a strong fram e, C D, on which the gearing, and also the axles vof the wheels and the drivers sea-t D', are

mounted. Internalcog-teeth b are provided in the drive-wheel, and into the same a pinion, E, meshes, the line-shaft F of this pinion extending across the front end ofthe machine on'topl of the frame G D, and carrying on its other end a bevel-pinion, G, which meshes into a bevel-pinion, H, ofthe pitman gear J K. The lineshaft F is supported by two boxes, c d, one on the front rail of the frame,

. and the other ontlie side rail thereof. The

forward rail of 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, las at g', for one of the forks l1l of a strong hanger, I, said hanger supportpitman-gear H J K and the finger` beam L. The other fork, h', of this hanger is braced upon a tubular extension, z', of the box o, upon which it plays loosely. These two forks thus hinged have their axis of motion in line with the line-shaft F. The hanger I may be made of cast metal, and should have a partitioned recess or depression, Il, in its rear lower part, for the reception of the inner end of the linger-beam L and the crank K of the pitinan, the latter being crooked and fastened by a hinge-joint, M, on the brackets of the4 hanger, and then shaped so as to run upon the ground when ,the machine is used for mowing. At the rear terminus of the hanger I a curved extension-bracket, l?, rises and terminates in. Aa flat liange, 13, which runs at right angles to the front side of the bracket I2 into a curved slotted and perforated guide-standard, O, as represented. A pin, l, is used to connect the lbracket of the hanger and the guide-standard the hangerl, so as to have its axis of motionA in line with the hinggeljoint M' of the fingerbeam, and concentric with the pitmanfshaft J.

i Bymeans of the hinge M the outer end ofthe finger-beam has freedom of motion to accommodate itself to the surface of the ground, and by means of the two joints g and M, with their auxiliaries, the finger-beam with cutting apparains may be raised at-both ends andheld lin a convenient position for transportation, or for cutting high above ground, the adjustment not interfering with the motion ot' the ngerbeam or its hingeM. And, as the two hinges are respectively in line with' the pitrnan-shvaft J and lthe line-shaft F, thegearing Willalways 'be ina position to operate knives at any elevation of the nger-beam. IThe pinion H, `mov.

ingwith the hanger I in the path of a vertical circle, rises'on the bevel-wheel G, but never changes its gearing relation. It will be seen fromFig, 3, the shield P' of shoe P is hinged to atubular extension, m, 4of the box n, through which the shaft J plays freely, and therefore it nor the hanger I, with the pitman-.gear, can be affected by any elevation or depressionl of the finger-beam L oreither of the hinges M and g, 'the whole'moving together on the, axis y 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 ot' the machine a pole-plate, N, which is constructed with an open slot, o, on its under side, is fitted aroundl the front rail of the frame C D, and held there of a separate plate, p, and two by means screws applied against the under side of the front rail of the frame. This pole-plate N has a circular hole, Q1, andl an oblong hole, o2, through it to receive the fastening-boltsof the pole. The oblong hole allows avvertical adjustment of the pole, while the construction of the plate as a whole admits, by simple 'loosening the screws, of a lateral adjustment thereof to the right or left, so as to bring the pole in s the center of draft.

The machine thus far described is adapted for mowing and for the adaptation ot the same to reaping and discharging the grain in bundles suited for gavels upon th'e ground,.at right angles to the path of thehorses. I elevate the cutting apparatus by the means, and, as above described, and attach a platform, Q,"to the back side of the finger-beam to receive the cut grain, andan automatic handrake to be operated by the driver of the machine from `his seat. The rake attachment consists of an angular standard, RRl R2, a crane-like jointed arm, U V, cam-truck W ,ttl t2, a supporting or regulating stale, Y, a pivoted rake, X, and

` hand-lever Z, all` supported upon the lingerbeam L, and locatedin close proximity to the Y through which the drivers seat D, and nearly over the inner front corner of the platform. The standard R Rl R2 is bolted upon the finger-beam L, near the heel of the cutters. rllheV angle or elbow R1, 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 drivers seat, and at the same'time it enables vme to' have the whole supported by the finger-beam, which is essential in order that the whole may be adjusted together and by the one set ot' means, whenever. an adjustment is necessary to cut higher or lower, and in the adjusting the respective part-s will conform to the motions of one another. `The inclined eye R2 of the standard receives this stale Y through itV and serves to support the, stale, while it allows the same freedom to Achange its bearing as the rake rises and falls and swings back and forth over the platform. The jointed cranelike Aarm U V is hung in bearings W W 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, as',

The part U of this arm has i as represented. its joint q in a `slot, fr, V,`so that the part U may rise and fall a short distance. Immediately below the point Where the crane-like armis hinged or jointed ot' the. swiveling part a short vertical extension, s, running down at right angles to the crane-like arm, is formed on the part U. 0n the lower end of this extension, which is cylindric a vertical'rolller, s', is tiXed so as to revolve. he bearing W, arranged below this roller, extends out at right angles to the upright standard R El R2 in the form of a triangle, or thereabout, andhas a cam groove or track on its upper side, which is formed by meanssof the outer segment-rail 11;,'the inner wavelike rail tl, and the springas represented in' gate-like section ot' rail 152 Figs. 2, 4, and 5.. '.Ih'e ro'ller s above described extends down below the rails into the eamtrack, andr moves between them when-the rake is operated to remove the grain from the platform, but outside of the outer rail, when the yrake 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,th e small spring-gate roller s 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 yas to prevent the return of the roller on the same line. The crane-like arm with rake-attached is operated by the Ahandlever Z bolted to a bracket, w, of the part V of said arm. .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 b.position'shown in dotted black lines,- the elbow of the cranelike arm will be caused to r'ise from the `vertitachment into a wholly-mechanical operating 3.261 y i s 3. The combination of a suspended hingejoint finger-beam and a sweep-rakemounted directly and wholly upon said suspended hinge linger-beam in aharvesting-machine.

4. So constructing and arranging lthe several parts of a two-wheeled hinged-bar harvester that the rake-head, mounted on a support attached to the inner end ofthe finger-bar or shoe, will occupy a position wholl y on the grain side of the in'ner Wheel.

5. The angular or knee attachment at the inner end of the rake-arm, for guiding it.

6. The combination of: cam, rake-standard, finger-beam, and platform yof a hinged machine, all connected together as described, so that the operation of the rake will not be interfered with in' passing over uneven ground.

7. The double track or camway on the platform side of the vertical rake shaft or pivot in a two-Wheel hinged-bar-machine.

8. The combination of the camway arranged in a plane parallel to the mkg-shaft, and the knee attachment to the rake-arm.

9. The combination of a sweep-rake supportcal position in which it has been moving from the point indicated in full lines to the oblique position 'shown in Fig. 2. This change is necessary in orderthat the rake-teeth, in 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 Zin a converse direction to what he last moved it. Thus moving the lever causes the roller to return, but on the outer corner of the segment-rail t, it being impossible, for want of length in the extensions, for it to stand vertical in its return, and therefore it maintains its oblique position, and in turn holds the raketeeth high enough to enable-them to clear the grain on the platform until the return stroke is completed and it-the roller`falls olf of the in an opposite direction upon the lever, and thus causes the rake again to sweep oi the grain from the platform.

he movements of the rake are repeated from time to time, as required, to deposit the cut grain in suitable bundles.

The arrangement described gives great control to the operator, both for the removal of heavy grain and speedy performance of the arm and a can against which the heel of the rakearm presses for holding down the rake to the platform while sweeping it oli'.

15. The arrangement and combination, in a reaper and mower, of the hanger I, curved 'guide O, hingejoints M and g, and shield P', of shoe P, or' their equivalents, constructed and operating substantially as and for the purpose described.

same, and withal the raking attachment is convenient to the drivers seat, and therefore the raking and driving may be performed by oneperson.

The bearing W, with its cam-track, may be extended and varied so as to accommodate the motionsvof the rake to the differentsizes aud forms of platforms, either for side or rear delivery of the cut grain,- and, if desirable,` under any circumst' nces, to couvert the atdevice, that may be ei'ected by attaching a pulley and suitable gearing to the main shaft of the drive-wheel 'and connecting the same with the lever Z but such change will hardly be desirable, as the hand operating gives full control of the rake in reaping thick and thin grown wheat.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A sweep-rake, wholly mounted upon the heel of the linger-beam, or on the inner shoev thereof', in a harvester which has its cuttin apparatus and platform hinged to the draftframe, lin such a manner that 'the rake-arm sweeps the platform from front to inner side, and maintains a correct position in relation to the linger-beam and platform during the rising or falling movements thereof on the joint or=joiuts. 1
