UNITED STATES REUBEN HOFFHEINS, ,OF

DOVER, PENNSYLVANIA IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters PatentV To all 'whom 'it may concern:

Be it known that [,REUBEN HoEEHE1Ns,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 that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specitica-tion, in which- Figure l is a front perspective view of my improved machine as arranged for Vcuttin g grain. Fig. 2 is a rear perspective view of the same in the form of a mower. Fig. 3 is a side view of the same as arranged for transportation. Fig. 4 is a perspective view of 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 igures indicate corresponding parts.

The invention embraced under this applica tion relates to the mode of combining a raking apparatus with a harvester.

My first improvement consists in the combination, in a two-wheeled hinged-joint machine, of adrivers seat mounted upon the main frame, with a raking -mechanism mounted upon the finger-beam, and rotating on a vertical 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.

My second improvement consists in the combination, in a two-wheeled machine, of a shoe with a `tinger-beam jointed in it, a rake standard and platform with an extension, J", 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 vdrive-wheels.

My third improvement consists'in the combin ation of thejointed iin ger-beam, inner shoe, and raking apparatus, as hereinafter explained.

My fourth 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 skilled in the art to make and use myinventioml will proceed to describe the construction and operation of the same;

No. 40,481, dated; November 3,1863; Reissue No. 2, |02, dated November 7, 1865.

but in doing soI wish it to be distinctly understood that I do not confine myself to the construction of the draft-frame, nor to any particular construction of the raking apparatus; but desire to include any style of doublewheeled hinged-joint machine, andany 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, represented in Fig.- el, is cast in one piece, in the form represented, the ends being left disconnected to facilitate molding and to reduce the weight.

B B are two driving or supporting wheels, adapted to turn on the axle C, but each, if desired, furnished With a pawl, b, taking into a ratchet, b', on the axle, so as to impart rotation thereto when the wheel is turning for-Y ward. y

b2 is a spring hearing against the square heel of the pawl b,'to hold it either in or out of gear, in Whichever position it may be set.

C is the main gear-Wheel on the axle C, which gears with a pinion, d, on the transverse shaft D, which carries at its other end a bevel cog-wheel, D', gearing with a bevel-pinion, e, on the crank-shaft E. K E is the crank-Wheel, mounted on the rear the end of the shaft E, and imparting motion to the cutter F by means of a pitmamj', which.

is provided with a swivel,j", formed of a screwthread and nut to permit the rolling of the linger-beam without straining or binding the cutter.

a represents a Hange cast upon the main frame for the purpose of imparting additional strength thereto, and alsoprotectingthe crankshaft E.

G is the linger-beam, attached atits respective ends to the inner shoe, El, and the outer shoe or divider, H. The inner shoe, H, is pivoted by its center ath to the drag-bar Iby a universal joint, and at its respective ends to guides h It', which work in 'vertical dovetail slots formed in pendantst' t on the drag-bar in such manner as to brace thebeamhorizontally while permitting it to turn freely on its axis, either for the purpose of conforming vto the undulations of the ground, to rise over an obstruction, or to be turned up edgewise and carried on' the machine in manner as representedin Fig. 3, the point of the divider H' resting in a staple in the side of the tongue K. The tongue is attached to the main frame-by means of two bolts, 7c', passing through it,and

through notches or holesjj orj'j" 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, or on the outside of the outer wheel, B', for cutting grass, as illustrated in Fig. 2. In either position an exten` sion, K', from the tongue affords a means for supporting the inner end of the finger-beam.-

This is effected inthe illustration given in Fig. l by a chain, J, rising from the extreme end of a rigid arm, J', which projects inward from the finger-beam or platform, and in the illustration shown in Fig. 2 by a chain, J2, attached at its lower end to a staple, h2, in the lateral stay-rod H2, and at its upper end to a segment-lever, M, fuicrumed at mon the rear end of the tongue, so that by raising the said lever the heel of the beam may be raised to any required height. A` rack, M2, holds the lever M in any position in which it may be placed.

H3 represents a track-clearer, pivoted in front to therearof thedivideror outer shoe, H'.

0n the rear of the inner shoe, H, is formed a lug, h4, for the attachment ofthe inner corner of the segmental platform l?. The said platform is secured to the finger-beam at suitable intervals by straps 0 and bolts o'.

N represents a caster-Wheel, secured adjustably to the outer edgeof the platform, and employed to carry the same at any desired height.

Q represents a grain-fender,pivotedin front upon the divider H', and adjustable in height at it its rear end' by a bolt placed in either of the holes q. l

On the inner side ct' the grain-platform, near the heel ofthe finger-beam, is firmly mounted a post, R, 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 of which may be bolted to the platform, the front of the shoe H, and the outer end of the rigid arm J', so as to secure the post in rigid connection with the platform and cause it to follow all the motionsaotl the latter. The post R is provided at its upper end with a cogged segment, S, and a segmental guideway, S', (see Fig. 5,) by Which the revolving rakes are turned and held in the required positions, as will be presently eX- T is an inverted crown-Wheel, provided with a vertical shaft, which is journaled in a box on the upper part of the post R. Rotation is com municated to the crown-Wheel T by an eX- tensible tumbling-shaft, U U', of square form, made in two parts, sliding one Within the other, so as to assume any length which the positions of the parts may require, and Work equally well in any position. The said extensible tumbling-shaft is connected at its respective ends by universal joints to pinions u' u2, the first, u', mounted upon the main frame and gearing With a pinion, as, on the axle C, and the second, u2, mounted on the post R and gearing Wit-h the crown-wheel T.

pairs upon the ends of horizontal shafts 'v e', journaled at right angles across the top or back of the inverted crown-Wheel T. The rake-arms form an angle with ythe shaft '12, the inclination of one arm of each pair being just in a converse direction of the other, so that when one rake or reel arm is over and down close to the platform the other will be at a very high position on the inner side of the machine. By this means the rake and reel arms will stand high enough above the draft-frame on .the inner side of the machine to move clear of the driver, who sits upon the machine in a seat, W, which is mounted upon the main frame, as shown, or in any other position on the frame that will give the greatest convenience and advantage from his weight and use of his hands in the management of the machine. l

At the junction of each of the rake or reel arms With the shafts i: t' is secured a cog-segment, t2, adapted to gear with the fixed cogsegment S, and in passing over the same to turn the reel or rake on that side toits nverted and elevated position, in which position it is held during about one-fourth of its revolution by a rigid arm, e3, resting on the segmental guideway s',and it will be apparent ,that the corresponding reel or ralre arm being rigidly secured tojthe opposite end of the same shaft will be held in its lower or Working position during the same period.

From the foregoing description it will be seen that my invention enables me to com bine in a self-raking harvester all the advantages derived from thetWo-Wheeled hinged-joint machine, and still use a rake that turns about an axis or revolves entirely around the same, and also at the same time have the driveror manager ride upon the main or draft frame in such r a position that his Weight may aid in counterbalancing the Weight of the rake and platform, and his hands may be conveniently employed for controlling the machine.

The use of the rigid arm J', projecting from the finger-beam or platform, and supporting the finger-beam, platform, and rake from the rearof the tongue at a pointbetween the drive- Wheels, diminishes the abrnptness of the motions of the cutting apparatus, platform, and rake Without restricting their freedom in conforming to undulations ot' the ground. This 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 of the platform.

The peculiar construction and attachment The rake or reel arms V V' are mounted in of the inner shoe adapt the finger-beam to roll freely on its axis in use, or to beturned over on its edge and folded compactly against the frame, as illustrated in Fig. 3, to adapt the machine to be moved from place to place.

The pawl or ratchet connection between the driving-wheels and' their axle adapt-s the machine to be turned or backed with perfect freedom, and also affords ready means for throwing the entire machinery out of gear, which is effected by raising the pawls out of the ratchets, where they will be held by the springs b2. I would here remark that any well-known style of two-wheeled draft-frame adapted for the purpose herein set forth may be used.

The operation is as follows: For cutting grain the parts are arranged as shown in Fig. 1. The successi Ve rake and reel arms descending, as the machine moves forward, in front of the'finger-beam, defect the grain backward toward the cutters in customary manner, and the rakes remove the cnt grain in compact gavels from the platform and deposit it ont of the retnrnpath 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 through a lever, as'before explained, vthe tongue being transferred to a position on the outside of the wheel B for the purpose ot' making the machine operate as a mower to better advantage.

The cutting apparatus may be thrown out of gear by moving the transverse shaft D longitudinally b v a lever, D2, and providing it with a pin, d2, which in one position of the shaft will fit a recess in the hub of the wheel, so as to impart rotation thereto, and in the dependently of the Wheel.

other position will permit the shaft to turn in- This lever may be moved by th hand or foot of the driver.

Havingthnsdescribed myinvention, what I claim as new, and desire to secure by Letters Patent, is i l. Thecombinatiominatwo-Whee1edhingedjoint machine, of adrivers seat mounted upon the main frame with a .raking mechanism mounted upon the nger-beam and rotating on a vertical axis, or one nearly so, substantially in the manner described, for the purpose of enabling the driver to'ride upon the machine while the rake is in operation.

2. Thecombinatiominatwo-Wheeledhingedjoint machine, of a shoe with a hinged joint in it with a rake and platform having an extension, J2, and with a draftframe, which snstainsthe weight of the cutting apparatus and raking apparatus with the platform attached at a point between the two drive-wheels.

3. The combination, with the hingedjoint machine, of thev inner shoe and raking appatus, substantially as described.

4. The combination of a revolving or turning rake, extensible tumbling-shaft, and driving shaft or axle of the main frame, substantially as described.

5. The combination ofa two-wheeled hingedjoint machine, a raking apparatus, and a drivers seat mounted on the main frame, substantially as described, and for the purpose set forth.
