DIVISION B.

, IMPROVEMENT IN HARVESTERS.

TO ALL WHOM IT MAY CONCERN: 4

IBe it known that JOHN Leim, ot' Massillon, in the-'county of Stark, and Stats of Ohio,vhas invented a new and useful/improvement in Reaping and Mowng Machines; and we do hereby declare the following to be a full, clear, and exact description of the saine, reference being had to the accompanying drawings, in which- Figure 1 is a plan of this machine. I

Figure 2 is a. side elevation of the same.-

Figurc 3 is a rear elevation of the same.

Figure 4 is a sectional elevation of the drivers seat, and the main driving bevel-wheel and pinion.

Figure 5 is an elevation of the rear end of the drag-bar.

Figure 6 exhibits the guard-finger in plan, rear, and side elevation.

That part of this invention embraced in this patent consists, iirst, in supporting the cutting appara-tus upon adjustable'caster-wl1eels, by means of which said cutting apparatus may be supported at any desiredheight above thc ground, independent ofthe main frame; second, in the devices for transmitting motion to the cutters;

- third, in the use of a rear caster-wheel to carry theyrcar end ofthe main frame and the cutting apparatus when the latter is folded for transportation. l

'I hat others may fully understand its construction androperaticn, we will describe it.

A A A are the timbers which form the main frame, and B B are the supporting and driving-wheels. These wheels are mounted loosely upon the axle C, aud are independently geared therewith by means of the ratchet l .D and pawls E, so that when' the machine moves forward either or both of the wheels B may cause the axle C N to revolve, and when the machine moves backward either or both of said wheels may revolve freely upon said axle. The bevel gear-wheel F is rigidly secured to thc shaft O and meshes with the ccgs ot' the bevel-pinion G which is loosely placed upon the end of the cutters driving-shaft H, but is prevented from revolving inde pendent of said shaft by a. spline and feather which vpen'ntsntid pinion to move freely in the direction of the length of said shaft to be brought into or thrown out of gear as desired. rIhe shaft H has its bearings in the boxes I I secured to the main frame. The geared cam-wheel J isvmountedupon the shaft H, near its rear end, and meshes with the cogs of thc corresponding geared cam-wheel K which is mounted upon the counter-shaft L revolving in boxes likewise secured to the main frame and parallel with the shaft H. Directly beneath the cam-wheels J K, and transverse to the main frame, is the sliding connecting-rod M,- which is caused to reciprocate by the cam-teeth N upon the cam-wheels J and K, and iu its reciprocations to move the cutters of the cutting apparatus to which said connecting-rod is connected. The cam-teeth are arranged at certain regular intervals upon the pcripheries of the cam-Wheels, and when said wheels are placed in mesh they are so placed in' respect to each other that the caurteeth on one wheel will exactly alternate with the corresponding teeth on the other wheel. The collars O O, upon the rod M, are so placed in respect to each other and to the wheels Jrand K as to insure the proper contact with the alternating teeth N, and thereby produce the desired reciprocation. For instance, during the revolutions of the two 'cam-wheels, the proper collar O first engages with one of the teeth N upon the wheel J; by this contact it is moved tothe left, and reciprocates the cutter in that direction also. As the cam-tooth N moves in the-.arc of a. circle, and the rod M is tangent thereto, the collar O soon passes beyond the iniiuence of the cam-tooth, and the rod ceases to move; but ldirectly it has ceased to move in one direction, one of the cam-teeth Nvupon the wheel K engages with the other collar O, and the rod M is returned to the place of starting; the spacings of the cam-teeth Nbeing so arranged that immediately after one wheel is disengaged the other will engage, and the rod M will continue to be reciprocatcd practically without intermission so long as the wheels .I and K continue to revolve. The stops P P limit the extent to which thercd M may he moved, so that a proper engagement cannot be prevented. The collars O extend entirely around the rod M so that as they become worn by use the rod may be-partially rotated on its-axis and ncwvsurfaces pre sented. The forked head Q is attached to the end of the rod M by a swivel connection, so that the said rodmay be rotated inV its bearings, as described, without changing the position of said head. The two branches of the forked head Q enclose between them the slotted standard R, which is erected upon the heel of the cutter-bar,

and the said bar and head are connected by a pin or bolt which passes through said slot and into proper orices in the heads Q. With this method of couneetingthe vcutter and its driving-rod, the vertical elevation of the cutting apparatus will makeno` liie'rence-withl the'postion of the stroke of the cutters.' T is the drag-bar, by means of which the cutting apparatus is secured'to thema-in frame and drawn forward when the machine is soimoved. The drag-bar T is pivot'ed at its frontend at a point further forward than the axis of the 'bearing and driving-wheels, so that its rear cud, to which the cutting apparatus 'is attached, may rise or fall freely with the undulatio'ns of `the ground,independent ofthe-position or movement of the main frame. The rear end of the drag-bar T is. prcvented'from moving laterally by the slotted plate or link U, which is'rsecure'd to the main frame, and projects laterally therefrom, so that the rear end of the drag-bar may pass through it., The downward vibrations of the drag-bar Will be limited by the loweuend of this slot-U, and then the weight of the in-ncr end of the cutting apparatus may be supported by the main frame. The rear end of' the drag-bar T is provided with projecting lugs V V, through which pivot-bolts W "W arc inserted in the same axial line, and by these pivot-bolts and lugs said drag-bar is connected withthe l inner shoe .A' of the cutting apparatus, which is provided with similar lugsB', through which the pivot-bolts W also pass,- thus forming a'hingc joint between the cutting apparatus and drag-bar, upon the pivot of' which the outer end ofthe cutting apparatus may rise or fall with lthe undulations et' the ground independent of the inner end; and it also follows that said inner end may correspondingly rise or vfall independent of the outer en d; and it still further appears' that by the union of the vibrating drag-har T and the hinge `joint at W the entire cutting apparatus may rise or fall independent of the main frame, to coliform to the uudulations of the ground over which the machine is being drawn.-

lvVhen mowing, the shoe-A'maybe permitted to slide upon the ground, but when reaping it isrnecessary to elevate it above the' ground a short distance, and so `maintain it without a'ecting its capacity to adapt itself to 'the undulations of the ground. l therefore attach to the rear end of' the drag-bar Tan adjustable casterwvheel C', upon which the rea-r end of said drag-bar may be carried, and thc cutting apparatus may still be free to rise or fall as before. The Swivel of the caster-wheel C' passes through a slotted plate, D', which is adjustable vcrtically, and clamped at any point by the screw Ewhich passes through the slot F and into the drag-bar. Thus the inner shoe A' may be elevated above the ground as high as may be desired in reaping grain, or only high enough to clear the surface of the ground, and thus avoid the unnecessary friction of a shoe sliding. upon the ground. The same requirements apply to the outer shoe G', and the caster-wheel H' is therefore attached to said shoe, and made adjustable by means similar to those employed at the inner end ot" the cutting apparatus, i. e., a slotted plate, I', and a set-screw, J', sc that the cutting apparatus may be supported at each end at any desiredk height above the ground, free to risc or fall with the undulations thereof, and independent of the main frame.

When moving the machine from place to place, the projection of the cutting apparatus sideways is incon- V venicnt, and I therefore construct my machine so that the cutting apparatus may be folded over and supported upon the mainframe during transportation, as shown by red linestin tic. 3. While so folded, the inner end may D, still rest upon the easter-wheel C', though it vis altogether preferable to raise said caster-wheel sc high that the rear end of the drag-bar T will rest at the bottom of the slot U, and be borne by the main framc .At the outer end of the cutting apparatus is ascraping track-clearer, K', pivoted to the outer shoe, so thatits rear end drags uponthe ground, and rises and `falls with the undulations thereof. In position it is oblique to the line ofv movement, as shown in iig. 1, so that as the machine moves forward that portion of the grass cut by the cuter sections of the cutter will be 'caught by rthe track-clearer and moved-laterally away from the standing grass, so

as to leave a clear path for the machine on its next round. The caster-wheelI-I 1s placed Vbetween the trackclearer K' and the standing grass, andtravels in the space cleared by said track-clearer. Y

It. frequently happens that it is desirable to elevate the points ofthe guard-lingers more than usual, and to this ond the forward 'part of the drag-bar T is pivoted to the slotted plate or slide L', which is placed in a recess cut in the side ot' the outer` bar A of the frame. The sides of said recess act as guides to prevent any movement'ot' the platc'L', except in a vertical direction, and its vertical movement is limited and controlled by the set-screw M. Y v

The guard-fingers N' are constructed as shown in tig. 6. The portion a which extends beneath the tinge:llbar W', and through which the screws are inserted to bind the finger to said bar, is provided at its front end with a vertical flange, a, which rests aganstthe front edge oi' the Enger-har, and is also constructed with oblique side edges, as shown in figs. 3 and 6, so that eaclrguard-nger shall bc supported on one side by the adjoi'ning finger; and I am enabled by this Construction to secure the guard-Enger to the ingehbar with three screws in each, instead offour, as might otherwise be necessary.

The clutch-rod 0', by which the bevel-pinion G is thrown into orout of gear, projects for convenience through a hole in the drivcrs seat P', and close to one end thereof, as shownin gs. 1 and 3; and I am enabled lby this construction to bring the end of said rod close to the drivers hand, and to make the stops Qi Q by Vindenting the side of the arm-hoard R' so that the pinion G may be thrown into or out of' gear, and so retained at the drivers pleasure.

At the rear of the main frame is the cnstcr-wheel S", which, when thc tongue T' is made rigid, does not touch the ground. But when the cutting apparatus is folded upon the main frame for transportation, as shown by red lines in fig. 3, the extra weight upon thc rear of the frame would tend to raise the forward end of the tonguein the neck-yoke and annoy the horses, so that at such times it is expedient to loosen the tongue, and permit the rear end of the frame and the weight of the cutting apparatus to rest upon thc caster-wheel S.

The'tongue T' is pivotefl to the main frame by the pin X', which passes through said tongue, and through the plates V', which are bolted to the main frame for that pu1'p ose` and it is made rigid or ilexiblc bythe presence or absence ofthe pin U', which is inserted into the t`ongue and through the plate V.

The driver's seat P is mounted upon the legs Y', which are bolted to the frame in fr ont of the seat. No

legs or supports are placed under the rear edge of the seat, and the elasticity ot' the legs Y permits the seat to yield with the motions of the machine suilcient to make the seat comfortable to the driver.

Having described this invention, what we claim as new, and desire to secure by these Letters Patent, is-

The combination ofthe adjustable 'caster-wheel H and outer shoe of the cutting apparatus, when said wheel is directly connected with said shoe, substantially for the purpose set forth.

The combination of'. the adjustable easter-wheel H attached tothe outer shoe with the exible trach-` clearing apparatus connected to said shoe inside of said caster-wheel, Substantially as shown and described.

In combination with the flexible cutting apparatus the two easter-wheels C and H', arranged and supporting said cutting apparatus independent etl the mainframe, substantially as described.

Supporting the heel of the drag-bar by the cnster-wheel connected thereto, substantially as described.

The combination, in a harvesting machine which hastwo supporting wheels, (a drag-bar flexibly connected at its front end with the mainframe, and at itsa'ear end `jointed to a cutting apparatus, which has cutters reeiprocated in straight lihes, and is free to rise or fall at either end with the undulations of the ground over which it is drawn, independent of the main frame, of an adjustable caster-wheel fo support the rear end of said main frame when the cutting apparatus is folded for transportation, and a tongue, which may be made rigid or flexible, by which the machine may be drawn forward, substantially as set forth.

Giving the cutter-bar a reciprocating motion by two cam-wheels J and K, in combination with the reciproeating and rotating connecting-rod M, the whole being constructed and arranged in the manner and for the purpose set. forth.
