. IMPROVEMENT iN lf'lARVESTERS.v

Specification forming part of Letters Patent No. 40,481, dated November 3, 1863; reissue No. 52,1072, dated November 7, 1865; reissue No. 2,490, dated February i9, 1867.

To all whom it may concern: Be it known that I, REUBEN HoFFHnINs, of Dover, in the county of York and State of Pennsylvania, have invented a new and useful Improvement in Combined Harvester and Rake and I do hereby declare the following is a full,elear,` and exact description of the same, reference being had to the accompanying drawings forming part of this speeiiication, and in which- Figure l is a front perspective view of my improved machine as arran ged for cutting` grain. Fig. 2 is a rear perspective view ofY the same in the form of a mower. Fig. 3 isa side view of the saine as arranged for trailsportation. Fig. 4 is a perspective view off-the main frame detached. Fig. 5 is a plan of the top of the post on which. the rake is mounted.

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

The invention embraced under this patent relates to the mode of combininga raking apparatus with a harvester.

My first improvement consists in the combination, in a two-wheeled hinged-joint machine, of a drivers seat mounted upon themainframe, with a raking mechanism mounted upon the finger-beam, and rotating on a -vcrtical axis, or one nearly so, substantially as hereinafter described,'for'the purpose of enabling the driver to ride upon the machine while the rake is in operation.

lMy second improvement consists in the conibination, ina two-Wheeled machine, of a shoe, with a finger-beam jointed in it, a rake-standard, and platform, with an extensin, J1, and a draft or main frame, which sustains the weight of the cutting apparatus 'and raking apparatus, with platform attached, at a point between the two drive-wheels.

"Wy third improvement consists in the combinationof the jointed fin ger-beam, inner shoe, and raking apparatus, as hereinafter explained.

Myfourth improvement consists in the combination of the revolving or turning rake, extensible tumbling-shaft, and driving-shaft of the draft-frame, in the manner .hereinafter explained.

To enable others nskilled in the art tovmalre and use my invention, I will proceed to describe the construction and operation of the saine, but in doing so lwish it to 'be distinctly understood that I do not confine myself to the construction of the draft-frame, nor to any particular construction ot' the raking apparatus, but desire to include any style of double wheeled hinged-joint machine, and any style of revolving rake, in combination with a seat upon the main frame, so long as the principle of operation is substantially the same as hereinafter set forth.

The main frame A A is cast in one piece, in the form represented, the ends being left disconnected to facilitate molding land to reduce the Weight. B Bl are nished with a pawl, b, taking into a ratchet,- bl, on the axle, so as to impart rotation thereto When-the Wheel is .turning forward. b2 is a spring, bearing against the square wheel of the pawl b, to hold it either in or out of gear, whichever position `it may be set. C1 is the main gear-wheel on the axle O, which gears with a pinion, (l, on the transverse shaft D, which carries at its other end a bevel cogwheel, Dl, gearing with a bevel-pinion, c, on the cranklshaft Ek El is the' crank-wheel, mounted on the rear end of the shaft E, and imparting motion to the cutter F by means of f1, formed of a screw thread and nut, to permit the rolling of the linger-beam Without straining or binding the cutter. arepresents a flange cast upon the main frame for the purpose of imparting additional strength thereto, and also protecting the crank-shaft E. G is the iingerbeam, attached at its respective ends to the inner shoe H and the outer shoe orv divider H. rlhe inner shoe His pivoted i by its center `at Ily 'to the drag-bar l by a uniresting in a staple in the side of the tongue K.

' the divider or outer shoe Il'.

universal joints to pinions u1 The tongue is attached to the main frame by means of two bolts, k1, passing through it, and through notches or holesjj orj1 j1 at one side of, or near the center of, the frame, so as to permit the adjustment of the said tongue to a position between the wheels for cutting grain,

as illustrated in Fig. 1,01` on the outside ofthe outer wheel Bl, for cutting grass, as illustrated in Fig. 2. In either position an extension, K, fromthe tongue affords a means for supporting the inner end ot' the finger-beam. rllhis is effected in the illustration given in Fig. l by a chain, J, rising from the extreme end of a rigid arm, J1, which projects inward from the fingerbeam or platform, and in the illustration shown in Fig. 2 by a chain, J2, attached at its lowel' end to a staple, h, in the lateral stay-rod H2, and at its upper end to a segment-lever, M, fulcrumed at m on the rea-r endet' the tongue, so that by raising the sa-id lever the heel ot' the beam maybe raised to 'an y required height. A rack, M2, holds the lever M in any position H3 represents a track-clearer, ypivoted in front to the rear of On the rear of the inner shoe Il is formed a lug, h, for the attachment ot' the inner corner of the segmental platform I. rlhe said platform is secured to the linger-beam at suitable intervals by straps O and bolts ol. N represents'a caster-wheel, secured adj ustabl y to the outer edge of the platform, and employed toy carry the same at any desired height. Q represents a grain-tender, pivoted in front upon the divider H, and adjustable in height at the rear end by a bolt placed in either ofthe holes q. On the inner side ofthe grain-platform, near the heel of the finger-beam, is firmly mounted a post, lt, which may incline over toward the main frame, as shown in Fig. 1. The said post is braced by stay-rods r r r, the respective lower ends ot' which may be bolted to the platform,

the front of the shoe H, and theouter end of' the rigid arm J1, so as to secure the post in rigid connection with the platform, and canse it to follow all the motions of the latter. The post 1t is provided at its upper end with a cogged segment, S, and a segmental guideway, S, (see Fig. 5,) by which the revolving rakesare turned and held in the required positions, as will be presently explained. 'Fis an inverted crown-wheel, provided with a vertical shaft, which is journaled in a box on the upper part ofthe post R.. Rotation is comlnunicated to the crown-wheel T by an extensible tumbling-shaft, U U, of square form, madein two parts, sliding one within the other, so as toassume any length which the positions of thc parts may require, and work equally well in any position. '.lhe said extensible tumblingshaft is connected at its respective ends by u2, the first, al, mounted upon the main frame, and lgearing with a pinion, u", on the axle U, and the sec- 0nd, u2, mounted on the post 1t, and gearing with the crown-wheel T. The rake or rcel arms V V are mounted in pairs upon the ends of horizontal shafts c o1," journalcd at right anglesv across the top or back of the inverted crownwheel T. The rake-arms form` an'angle withv the draft-frame, on the inner side of the mav chine, to move clear `of the driver, who sits. upon the machine in a seat, W, which 1s mounted upon the main frame., as shown, or in any other position 011 the frame that will give the greatest convenience andadvantage from Ahis weight and use of his hands in thel management ot' the machine. At the junction of each of the rake or reel arms with the shafts 'vul is secured acog-segment, o2, adapted to gear with the fixed cogged segment S, and in passing over the same to turn the reel or rake on that side of its inverted and elevated position, in which position it is held during about onefourth of its revolution by a rigid arm, c3, resting on the segmental guideway S1; and it will be apparent that the corresponding reel or rake arm, hein g rigidly secured to the opposite end of the same shaft, will be held in its lower or working position during the sameporiod.

From the foregoing description it Will be seen that myinvention enables me to'combine in a self-rA king harvester all. the advantages derived ,rom the two-wheeled hinged-A joint machine, and still use a rake that turns about an axis, or revolves entirely around the same, and at the same time have the driver or manager ride upon the ma-in or draft frame in such a position that his weight mayaid in counterbalancing the weight ot' the rake and platform, and his hands may be conveniently employed for controlling the machine. The use of the rigid arm J1, projecting from the finger-beam or platform, and supporting the 1 ringer-beam, platform, and rake from the rear ot' the tongue at a point between the drivewheels, diminishes the abruptuess of the motions of the cutting apparat-us, platform, and rake without restricting their freedom in conforming to undulations of the ground. ThisV is the result while cutting grain with the machine, as shown in Fig. l; The peculiar devices for transmitting motion to the rake adapt it to act equally well at any height. or

angle ofthe platform. The peculiar construction and attachment of the inner shoe adapt the linger-beam to ro'll freely on 'its axis in use, or to be turned over on its edge, and

. folded compactly aga-inst the frame,.as 'illus- 'trated in Fig. 3, to adapt the machine to be moved from place to place. The pawlv or ratchet connection between the driving-wheels and their axle adapts the machine to be turned or backed with perfect freedom, and also af-y fords ready means for throwing the entire machinery .out of gear, which is eected by rais- Vof the driver. i

iiig the pawls out of the ratchets, where they will `be held by the sprin gs b2. Iivould h ere remark that any well-known style of two- ,Wheeled draft-frame adapted to the purpose herein Aset forth may be used. f

The operation is Ias followsrUFor cutting grain thelparts arearran ged as sho\vn in Fig. 1. The successive rake andE reel arms, descending,- (as .the machine moves'dorivarim in front off the finger-beam, deilect theV grain backward toward the cutters in the customary manner, and the rakes remove the cut grain in compact gavels from the platform, and deposit it out of the return path of the horses. In mowing, the platform and reel are removed, and the cutter is left perfectly free, being suspended on a chain, by which it is raised and lowered throdgh arlever,l as beforeexplained, the tongtie biiligtransferredI to a pgsition on the outside of the viiheel B1, forthe purpose of `inakingthe machine operate asa mo'iver'to b'etter advantage. The cutting apparatus may be thrown' out of gear by moving the transverse shaft D longitudinally by lever D2, and providing it with a pin, d?, which, in one position ot the shalt, will iit a recess in the hub of the Wheel, so as to -ii'vnpart rotation thereto, and-in the other position will permit the shaft to turn independent-ly of the wheel.- This lever may be moved by the hand or foot Having'tlius described my invention, what I claim as new under this patent isf- 1. The combination, in a tivo-wheeled hngedjoint machine, of a drivers seat mounted upon Vthe main frame, with a raking mechanism mounted upon the lingenbeam, and
