IMPROVEMENT In HARVESTERS.

TO A LL WHOM ITMAY CONCERN:

Be it known Athat I, JOHN` F. CODDINGTON, of Bound Brook, in the county'ot' Middlesex, and State of New. Jerseyfhave in'ventedcertain new and useful Improvements in fI-larvesters `and'I do hereby declare thatr the following is a. full, clear, and -exactdescription ofthe same, reference being'had to the accompanying drawings, making a-portion of this specification,` in which .Figure 1 is a. plan view-of a harvester constructed according to my invention.

Figure 2 is a vertical longitudinal section'ofthesame, taken in the line x :v of iig. 1.

Similar lett'e'rs of reference indicate corresponding partsin both figures.

This invention consists in certain novel means, whereby thc'construction of harvesters may be to a certain extent simplified and cheaponed, and whereby a'more facile and efficient operation may be secured than has hitherto been found practicable inmowing and reaping-machinery.

To enable others to understand the construction and operation of my invention, I will proceed to describe it with reference to the drawings.

The shape and configuration of the cast-metal main frame A of the machine are shown more fully in iig. 1, three of the corners of this frame bein'g rounded, while the fourth, indicated at a*, `is extended forward, with itsV two outer edges `at right angles to each other, all as represented in iig. 1, just mentioned. This constructionof the main frame renders it very compact and strong, and capable of `being very easily manufactuiied.

This frame is further provided with an inner longitudinal portion at or n'ear its centre, which serves to support the seat .A= andto furnish a journal-bearing for the rear end of the shaft c', which carries the spur-wheel d, and bevel-pinion c, in range with and at right angles to the axle a. An opening is provided at one of. the' rear corners of the main frame, and in thislopcning is placed the tool-box I3, the outer side of which is'of` semlicircular form,to correspond with the surface of the corner at which it is situated. By'arranuing the toolbox in this position, it is not only rendered very convenient of access from the d'rivcrs seat Ai but is also caused to occupy space not required for other purposes. Passing transversely through the main frame is the driving and supporting-axle a, furnished at its ends with the wheels Big-connected therewith by pawls andl ratchets, in any ordinary or suitable manner; also provided upon tho axle a, and working through an opening formed at or near one side of the main frame, is a bevel-whoel, c, which gears with a bevel-pinion, c, arranged forward of the bevel-wheel just named, and upon a shaft, c', which-is situated at right angles to the axle, and

u works in suitable bearings provided upon the under side of the maini'rame. Placed loose upon the shaft c', is

a spur-wheel, al, to which a limited movement upon the shaft inay be given by'n'eans hereinafter presentlydescribed. The inner sides of the pinion c and the spur-wheel d are so formed as together to constitute a clutch, which insures the rotation of the spur-wheel by that of the pinion, when the two are brought together .and the machine is drawn along.

Projectingdownwardifrom the main frame are two vertical hangers, e, formed at their lower ends with bearings, which support a horizontal shaft, j', arranged underneath and parallel with the shaftc, and having attached thereto a. spurpinion, di, which gears into the spur-wheel d. Furthermore, at the forward end of this :shaftfis provideda crunk,f, which, by means of the ptnian fik, operates the sickle C on the finger-bar 0*, -the latter being thus actuated, as the machine is drawn alonggby the power transmitted from the axle a, through the several 'gear-wheels and pnionsjust hereinbeforc described,

By thus arranging the sickle-driving systeni of. gearing wholly in front of the axle, and at one side of the main frame, the gearingis brought into a very compact condition,and also enabled tolact with very great directness and consequent etlicieney in operating the siclile,.as.just set. forth; and furthermore,l the shaft f carrying the crank f and other pinion dii, being arranged directly underneath the shaft c', any lateral-movement of such crank-shaft, which may occur from the wearing of its bearingsis prevented from, causing the Y pinion d* to either jani into orhe brought away from the spur-wheel d, tho position of the teeth ofthe pinion di, in case of such lateral movement on the part ofthe crank-shaft, being but slightly changed with reference to s. l o,o51

those of the spur-wheel. The hub z', at the forward 'side of the spur-wheel, is formed with a eircumferentialgroove, into which extends the forked end of an elbowlever, m, which operates to clutch ,or uncluteh the spurwheel-with or from, as the case maybe, `the pinion 0*, by moving such spur-wheel longitudinally upon its Shaft. The elbow-lever m hns its innermost varl'n formed ofa spring, m*, and connected with the lower end of an upright v lever, r, pivoted to a short upright standard, s, lat the side of. the main frame, in' such manner that by moving such lever in one direction, it will operate therelhow-le'ver m to bring tbe spur-wheel d away from the bevelpinion c*, to stop the movement of the sickle, and when moved in tlf'e opposite direction will bring the spurwheel inward to clutch with the pinion, to insure the driving or operation ofthe sickle, as hereinbefore explained. i Thellever mois retained in eitherp'ositionfby 'ttinginto notcbesa, provided at the top or upper end of the standard, so that-by -the interposition ofl the spring ml, the lever 'r muy be moved at a time when the clutch willA not yield, owing to' the tensionof the sickle, and said lever having been eo moved, the moment'the crankpin arrives at its dead-centre, the wheel will be thrown out of gear by the'action of -said spring. Projecting laterallyfrom the corner or portion a* of the main frame, and in front of the` adjacent wheel Bi, is an extension, rt, extending back freni which tothe outer end'of the axlen, is a bar, 3*. The linger-diar- C`l is furnished at its innerextremity with two arms a; which are pivoted to the lower ends of vertical sliding bars E, which work through suitablesoeketsr, formedmpon the bar 5*, the sliding bars' being prevented from dropping out of thevsockets by pins r'passing through holes in `their upper ends; this mode of connecting the linger-bar with the main fram-e, enabling the former to readily adapt itself to the surface of tho groundwhen the machine is in use`. Pivoted to thebar sl, on a pivct longitudinal therewith, is a lever, F, the lower end of which is connected by a. chain, w, with the inner end oftbe cutter-har, and' the upper 'end of which has' attached to it one extremity of a chain, w?, which passing inward and downward under n pulley, shown in dotted outlines at w', pivoted under the part aliof the main frame, is attached to lhefare-shaped lower portion y of a lever, G, in`sueh manner that by forcing backward the lever G, thebain 10?, acting through the lov-er l" and chain 2v, will lift or raise the linger-bar into the vertical or nearly vertical position desirable when the machine is not in use. The sickle C, when the inger-bar isin this vertical position, is prevented from slipping longitudinally from..

the finger-har by Aa. small transverse sliding piece, ,2, Working in a' transverse guide at the inner end of the fingerbar, and capable of being pushed inward past the inner end of the sickle, before lifting the finger-bar, to 'secure the result just mentioned. v y v What I claim as my invention, and desire to secure by Letters Patent, is 4 1'. The arrangement of the shaft c', carrying the bevelfpinion 0*, and spur-wheel d, and the shaft f, furnishedwith the spur-pinion dit, and crankf, at that part of the main framein front of axle, and between the wheels 13:11, and operating in connection with the bevel-wheel c, on the axle, and the pitinan f" effi-'the sickle, substantially as and for the purpose specified. v

2. The elbow-lever m, constructed with a spring or yielding arm, mi, for operating the sliding-clutch wheel (Z, substantially as set forth. f

' 3. The arrangemcntvof the elbow-lever m, cireumferentially grooverl huh z', of the bevel-wheo1 e, lever r,

and standards, substantially as and for 'the purpose specified. i

4. The transverse sliding piece e, arranged at the inner end of the linger-bar c", and in relation with the sickle C, substantially as and for the purpose specified.
