TO ALL WHOM IT MAYCONCERN: f

Be itk'nown thatpI, ANTONY SHBANCK, of Cleveland, in the county o f Cuyahoga, and Stute of Ohio, have invented a. new and improved Grain and Grass-Harvester; and I do Vhereby declare that the following is'a full, clear,`and exact description'thereof, which will enable those skilled in the art to makennd use the same,` refere-y ence. being had tothe accompanying drawings, forming part of this specification.l

This invention relates to a new and improved machine forcutting standinggrain and grass, and it consists' its a. new and improved sickle-driving mechanism, andina. peculiar construction and arrangement of various parte@ connected with the,`machinc, as hereinaftcrfully shown and described, wherebyseveral advantagesare obtained 1 as hereinafter s et forth.` 1n the accompanying sheet of drawingsi I i y Figilre 1 is `la plainor top view of my invention. v Y

Similar letters of reference indicate corresponding parts.

A represents 'the main frame of the machine, mountedon two wheels B B', the axle, C,'of which is fitted in suitable bearings, a a, attached to the under side of the main frame. The wheels B B are fitted loosely Aon the axle, and on the latter, at or nearv each end, there are, secured by pins b, collars c, provided each with a circular disk, D, having two Bauges d d projecting from their outer face sides. v

The .inner ends of the hubs e of the wheels B B are formedfwith cylindrical boxes E, to t against the disks D, and over their flangesA d d, the inner peripheries of the boxes E being`provided or formed with ratchetteetl" f, into which pawlsF engage. These .pawls are shown clearly in fig. 4, two of them being fitted in each box E, 'and each of them provided with two guide-rods g g, which pass along through the other, spiral springsh being fitted on the guide-rods between the pawls, and having a. tendency to keep the same spread apart and in contact with the ratchet-teeth f.' The pawls are connected with the axle C, and made to turn with it, in consequence of the flanges d of thedisks D fitting in recesses'i in the pawls.

By this arrangement, when the machine isV drawn forward, and thev wheels B B turn in the direction indicated by the arrow 1, tig. 4, the wheels are madelto turn the axle C, in consequence of the-teethf ofthe boxes E engaging with the pawls F, but whenV the machine is ba-cketl, the teeth f will slip over the pawls without turning-.the axle, and no motion will begiven to the working parts of the machine. This will be fully understood by referring to fig. 4. I 4

On the axle C there is fitted rloosely into a. hevel-pinion, I, on the front end of a drivingshaft, J. On the axle C there is also'iitted loosely a drum, K, which is toothed nt its inner side or periphery, as shown at j, sa-id teeth j gearing into a pinion, L, which is fitted loosely on an axis, l, projectingfrom a fixed plate, M, which is between the drum K and the bevel-wheel H, the plate M beingbolted to the main frame'. The pinion L gears into alpinion, N, attached to and concentric withthe'bevel-wheel H, (see iig. 2.) l v It will be seen that the only connection between the bevel-wheel H and the drum K is through the medium of the piuions L and teeth 7' of the drum. The drum K is connected with the axle C, when the machine is at work, by ineens of a clutch, O, themovable part m of which is actuated by a lever, mx, arranged in any proper wuyto connect the drum K to the axle, and'ldisconnect it therefrom. When the drumK is disconnected frein the axle, all the working parts of the machine cee-se to operate. i

P represents the finger-bar which i'sat the rear of the wheels B B', and has the front end of its innershoe. Q provided with a collar, R, which/is'ftted loosely ou the rear end of a rod, S, which has a longitudinal position under thc main frame A, and is curved upward at its frcint end, and connected .to the front end of the main frame by a joint, 7i, which allows the rod S to play or work up and down in a vertical plane. The collar R is ullowed to turn on .the rofl S, und it will be seen that by this arrangement the cutter-bar will readily 4conform "lic the inequulticsof surface ovorvwhich it may pass. The finger-ber is bracedl hy a. bar, AX,onc end of which fis connected lay-5t pivot-.bolt to the shoe Q, and th opposite end connected by a. pivot-bolt to the outer side bar `aisleeve, G,ha,ving'a bevel-wheel, H, on its inner end, which gears of the main freine, which projects considerablybeyond .the'rer of the same. The -ngewbar is supportedby dju'stable 'rollers ax, *one attached to'eachshoe.' By. adjusting theerollers highenor lower, the -'g1-assoigrain 'muy be cut at the desired height from the surface of the ground.

'In order to rzflse theiinger-bar so that'it mny"olear obstructions,-I attache rod,4 T, Itothe finge'pbargend .to a' thimble'o, on rod S, solid rod .phasing through a. slot in e' bent lever, U,l which is pivoted tmo'ne side of 'the moin frame; anti-is actuated by n l'ever, V, in convenient reuchof lthe driver on'his peut, W: This seat W in 'supported bytwo curvedsprings pp, thelower'endsof'I xghichn're attoched toslides g g, ltted on tiro parallel bars on the main freine, and Secured atany point on Suid bars by-Set-screws r r.- By this arrungement 'the seat muy b e adjusted further forward orbnck-'ward-"as muy be required, in ode to counterpoisg olibalauce the machine. v

The sickle Y may b e arranged on thenger-bar in the .usual wey, and it is driven byu connectingfrod, Zg' froin n-crankfwheel, s, on the rear end of the shuftJ. The' drauht-pole is attached Lt'o the fronten'dof the min frame A, between thewlug's t t, having vertical oblong slots'in' them, throughv which a. bolt, u', passes. By lthic'nrrengeuientthe draught-pole muy be attached'tc the`-main frame at 9. higher OilQWer-point, to suit the -size of .theteam,.and`to keep the machine in horizontal position.`

I cfaim as new, and desire to secure by Letters Patent- 1. The drum K, placed .loosely on the' axle v(Lend .prorided with the internal teleth j, the 'Pinion'Lycon .greeted with the fixed plate M; and the' pinion N aitt'ached -to thejbevel-whelH, placed looselyl on theaxlekC;
