Division A.

IMPROVEMENT IN HARVESTERS.

TO ALL WHOM IT MAY OONOERN:

Be it known that JOHN LONG, of Massillon, inthe county of Stark, and State of Ohio, has invented a new and useful Improvement in Reaping and Mowing Machines; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figurel is .a plan of this machine.-

Figure 2 is a side elevation of the same.

Figure 3 is a rear elevation of the same.

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

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

Figure (i exhibits the guard-tingerin plan, side, and rear elevations.

That part of this invention embraced in this patent consists in the connections of the cutting apparatus to the main frame by higing the same to' a flexible drag-bar, Ste.

That others may fully understand its construction and operation we will particularly describe-it.

A A A arepthe timbers which form the main frame, and B B are the supporting and driving-wheels. These wheels are mounted loosely upon the axle C, and are independently geared therewith by means of the ratchet 'D and pawls E, so that when the machine moves forward either or both of the wheels B may'cause theaxle C to revolve, and whenthe machine moves backward either or both of said wheels mayrevolve freely upon said axle. The bevel gear-wheel F is rigidly secured to the shaft C, and meshes with the cogs of the bevel-pinion G, which is loosely placed upon the end of the cutters driving-shaft H, but is prevented from ,revolving independent of said shaft by a. spline and feather, which permit said pinion to move freely in the direction of the length of said shaft, to be brought into or thrown out of gear', as desired. rlhe shaft H has its bearings in the boxes I I secured to the main frame. The geared cam-wheel J is mounted upon the shaft H, near its rear end, and meshes with the cogs of the corresponding geared camp-wheel K, which is vmounted upon the counter-shaft L, revolving in boxes likcwise,secured to thc main frame and parallel with the shaft H. :Directly beneath the cam-wheels J K, andtransversc to the main frame, is the sliding connecting-rod M, which is caused to reciprecate by the cam-,teeth N upon the cam-wheels J and K, and in its reciproeations to move the cutters of the cutting apparatus to which said connecting-rod is connected. The cam-teeth N are arranged at certain regular intervals upon the peripheries of the cam-wheels, and when said wheels are placed in mesh they are so placed in respect to cach other that the cam-teeth on one Wheel will exactly alternate with the corresponding teeth on the other wheel. 'lhc collars O O, upon the rod M, are so placed in respect to each other and to the wheels J and K as to insure the proper contact with the alternating teeth N, and thereby produce vthe desired recipro-v cation. For instance, during the revolutions' of the two cam-wheels the proper collar O first engages withone of the teeth N upon the wheel J; by this Contact it is moved to the left, and reciprocates the cutter in that direction also. .As the cam-tooth N moves in the are of a circle, and the rod M is tangent thereto, the collar `O soon passes beyond the inuence of the cam-tooth, and the rod ceases-to move; but directly it has ceased to move in one direction, one of the cam-teeth N upon the wheelAK engages with the other collar O, and the rod M". is returned to the place of starting; the spacings of the cam-teeth N being so arranged that' immediately after one wheel is disengaged the other will engage, and the rod M will continue to bc reciprocated practically without intermission so long as the wheels J and K continuato revolve. The stops P P limit the extent to which the rod M maybe moved, so that a proper engagement cannot be prevented. The collars O extend entirely around lthe rod M, so that as they become worn hy use the rod may be partiaIIyrotated onits axis and new surfaces presented. The forked head Q is attached to the end of the lod M by a swivel connection, so that the said rod may be rotated in its bearings, as described, without changing the position of said hea-d. The two branches of the forked head Q enclose between them the slottedstandard 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 orifices in the heads v IVit-h this method of connecting,r the cutter and its driving-rod the vertical '2 aseo elevation of the cutting apparatus will make no diiference with the position of the stroke of the cutters, T is the drag-bar, by means of which the cutting apparatus is secured to the main frame and drawn forward when the machine is so moved. The drag-bar T is pivoted at its front end at a point further forward than the axis of the bearing and driviug-whcels, so. that its rear end, to which the cutting apparatus is attached, may rise or fall freely vwith the undulations of the' ground independent of the position or movement of the main frame.

The rear end ofthe drag-bar T is prevented from moving laterally by the slotted plate or link `lll", which is` secured to the main frame, and projects laterally therefrom, s o that the rear end of the drag-bar may pass through it. The downward vibrations of the drag-bar will be limited by the lower end of this slot U, and then the weight of the inner 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 are inserted in the same axial line; and by these pivot bolts and lugs said drag-bar is connected withthe inner shoe A' of the, cutting apparatus, which is provided with similarlugs B',`tl1rough which the pivot-bolts W also pass, thus forming a hingejoint between the cutting apparatus and drag-bar, upon thcpivot of. which the outer end ofthe cutting apparatus may rise or fall with the undulations ot' the ground independent of the inner end, and itralso'fo'llows` that said inner end may correspondingly rise or fall independentof the outer end; and it still further appears that by the union of the vibrating drag-bar T and the hinge joint at W the entire cutting apparatus may rise or fall, independent of the mainframe, to conform to the undulations of the ground over which the machine is being drawn. v l v i Vllhen.V mowing, the shoe A' may be permitted to slide upon the ground, but when reapingl it is necessary to elevate it above the ground a short distance, and so maintain it without affecting its capacity to adapt itself to the undulations of the ground. I therefore attach to the rear end of the drag-bar T an adjustable caster- .wheel, C', upon which the rear end of said drag-bar may be carried, and the 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 vertically, and clamped at any point by the screw 'E' which passes through the slot F and into the drag-bar. Thus. the inner shoe Ai-may be elevated above the ground as high as may be desired in reaping grain, or only high enough to clear t-hc 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 s'hoe, and made adjustable by means similar to those employed at the inner end'of the cutting apparatus, e., a slotted plate, I', and a set-screw, J', so that the cutting apparatus may be supported at each end, at any desired height above the ground, free to rise or fall with the undulations thereof, and

independent of the main frame.

Then moving the machinel from place to place, the projection of the cutting apparatus sideways is inconvenient, and'I therefore construct my machine so that the cutting apparatus may be folded over and supported upon the main frame during transportation, as shown by red lines'in iig. 3. While so folded the inner end may still rest upon the caster-wheel C', though it is altogether preferable to raise said castor-wheel so high that the rear end of the drag-bar T will rest at the bottom of the slot U and be borne by the mainframe. `At the outer end of the cutting apparatus` isa scraping track-clearer, K', pivotcd to the outer shoe so that its rear end drags upon the ground, and rises or falls with'the undulations thereof. .In position it is oblique to the line of movement, asshown in tig. 1, so that as the machine moves forward that portion ofthe grass cut bythe outer sections of the cutter will be caught by the 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-wheel H' is placedbetween the track-clearer K' and the standing grass, and travels in the space cleared by said track-,cleared i j It frequently happens that it is desirable to elevate the points of the guardngers more than usual, and to this end the forward part of the drag-bar T is pivoted to the slotted plate or lslide L', which is placed in a recess cut in the side of the outer bar A kof the frame. The sides ofl said recess act as guides to prevent any movement of the plate L', except in a vertical direction, and its vertical movement is limited and controlled by the set-screw M'. n v

The guard-ngers N are constructedvas shown in fig. 6.v The portion n which extendsl beneath the finger-bar W', and through which the screws are inserted to hind the linger to said bar, is provided at its front end with a vertical flange, a, which rests against the'front edge of the finger-bar, and is also constructed with oblique side edges, as shown in figs. 3 and G, so that each guard-linger shall be supported on one side by the adjoining finger; and'I am enabled, by this construction, to secure the guard-finger to the finger-bar with three screws in each instead of-four, as might otherwise be necessary. .4 v i The clutch-rod O', by which the bevel-pinion Gr is thrown into or out ofge'ar, projects for convenience through a hole in the drivers seat P', and close' to one endthereof, as shownin figs. l and 3; and I am enabled,

by this `construction, to bring the end of said rod close te the drivers hand, andto make the stops Q Q b'y indenting the side'of the arm-board l", lso that the pinion Gr may bethrown into or outvof'g-ear, and so retained at the driver's pleasure. 4 l v l `Atth'e rear of the main frame is the caster-wheel S", which may be adjusted vertically so that it may or may not touch thcground, But when the cutting apparatus is folded upon .the main frame for transportation, K- as shownfby red lines in fig. 3, the extra weight upon the rear of the frame would tend to raisev the forward f end of the tongue' in the neck-yoke and annoy the horses, so that at such times it is expedient to loosen the tongue, and permit therear cnd of the frame and the weight of the cutting apparatus to be supported by the I caster-wheelS'.

I The tongue T' is pivotcd to the main frame by the pinXQlwhich passes through said tongue .and through the plates V', which are bolted' to the main 'frame for that`purposc', and it is made rigid or flexible by the presence or absence of the pin U', which is inserted into the tongue and through the plate V.

g 2,660 U I The driversI seat P is lnounted upon the legs Y','wliieh are bolted to the frame in front of the scat. No legs or supports are placed under the rear end et' the seat, and the elasticity of the legs Y permits the seat to yield with the motions of the machine sufficient to make the scat comfortabieto the driver.

Having described this invention7 what we claim as new; and desire to secure by these Letters Patent, is The combination in a machine having two independent driving-wheels o'4 a single drag-bar flexibly conneet-ed at its frontend with the main .frame forward. of the axis of the suppcrting-wheels, its rear end free to rise or fall independent of said main frame, and connected with the main shoe by two joints, one forward of and the other in rear of the sickle, for the purpose of atbrding the cutting'apparatus firm support, ting citherendJof the saine to rise or fall with the undulations ofthe ground over which it is drawn, s as described.

and permitubstantially Connecting the main shoe ,of a cutting apparatus, which has vreciprocating cutters, with a single drag-bar flexibly connected with the main frame at its front end, and its rear end free to riscand fall with the undulations of the ground, independent of the main frame, by means of projectingjoints, one forward of and one in rear of the sickle, so as to leave a ele'ar space lbetween said jointsand beneath said drag-bar through which the cutters connecting-rod may be reciprocated, substantially as described.

The combination of thc following instrumentalities in a harvesting machine, viz, two independent driving and supporting-wheels a main frame, which carries the gearing; a tongue, which may be 4made rigid or exible;

a single drag-bar, ilexibly connected at its front end with the main frame, and. its rear end free to rise 01' fall independent of said main frame; and a cutting apparatus which has reciprocating'cutters, and is liexibly connected to the rear end of said dragLbar, so that either end of said cutting apparatus mayrise or fall with the undulations of the ground over which it is drawn, substantially as described.

The combination, in a harvesting machine which has two driving and supporting-wheels, and a cutting apparatus which has reciprocating cutters, of a single drag-bar ribrating vertically "upon a joint at its front end, and flexibly connected at its rear end with said cutting apparatus, and a vertical slotted retaining link or plate to prevent any lateral movement of the rear end of said drag-bar, and to limit its vibrations downward so as to support the weight of the Cutting apparu-tus when folded upon the machine for transportation: substantially as set forth.
