Specification -forming part of Letters Patent No. 61,944, dated February 12,.1867 Reissue No. 7,83 0, dated a September 4, 1877 application filed May 21, 1877. I Y

.'To all iwhom i t myeoncerh: I

Be it-knownthat I, JAMES S. Mmsmvof Lewisburg, in the county of Union and-State of Pennsylvania, have invented certainlnew "and exact, description. A

My invention; relates to a convertible or combined harvesting -'m'achine tha't is, 7 one which can be used either as a reaper or as a mower-of thei'class known as two-wheeled, i

hinge-joint, rear c'ut harvesters.

Thefirst-part of my-in'ventionrelates to the mainframe. Its"object 'is-to' combine strength and lightness, and to provide supports for the gearing,drivers seat, and tongue, ajswell a receptacle for tools to which end'my improvement consists in casting the main frame "in one piece with a toolbox; which form's a 'streggthening-braoefend with"'recesses or journal-boxes for the shafting; as hereinafter bodiedkin one-machinepFigurel isfa plan view,- partly in section, through one of the more fully is'et'forth. The object of the next part of my invention ism enable theiiriver,-wliile seated upon "the ina'chine, read'ily to rock'or'roll'the'flnger-bea'm exihllyto tip the cutters g' 'to which endfmy improvement consists in combining-hfmain flame. mounted upon two wheels, and carrying a seat forthe driveifi'afinger-jbeam united n dragbar, connei'zted}lat it'sfforwar'd' end with the main frame by aconpling-link a; lateral brace oncoupling arni pivoted to fthe drag-'berinear the :sh0e;,: and a'litjtin'g lever pivoted onfithe mainframe between the' dri'v- 'rng wheels, moving 1 parallel therewith, and connected with the coupling link,' and proiided with axijetent, whereby the' froii't end of e drag barfiiiay 'beraised; lowered; or locked in any desired position. .1 p- The object ot"thej next partof my invention is to enable thefdriverwliileriding upon the Linachine to raise and lower the cntting apparetus, as well 'as to it; to whicnendi'my improvementconsists in combining a main fifame mounted upon two wheels and carrying eseatfor the driver; "a laterally-projectingcutting apparatus hinged to'th'e main frame,'with b? I 'ng apparatus mounted on therearof the "mainframe, and another lifting' apparatus mounted onthe front of the main frame, and

linked to a drag-bar, whereby either end of I 1 the-drag-bar maybe raised andloweredas reqnired. I I p I The-next part of my invention relates to the platform upon which the grainfalls whenfirst out; its objects bein'gsoto eonn'ect's'aid platform with the mainxframe that the'driv'er can, from his seat on the machine, elevate or depress the frontend of the. grain-platform at pleasure, which end I attain by combining two'main supporting and driving wheels,- a main frame mounted thereon,'e*finger-beam connected with the main fraine' by a'hinged drag-bar and coupling-arm; a platform connected with said 1 finger-beam and supported upon caster-jw1ieels," and a rocking lever mounted npon-the'main frame andco'nnectd with the front end of the drag-bar, whereby the driver from'his seat can raise or lower the cuttiu-gabparatus. .1 Y

' In theaccompanyingdrawings two main supporting and'drivin'gwheels are shown as mounted loosely. upon an axle, B, turning in boxes or bearings on the' under sideof the main frame. These wheels are connected with the axle byrthe usnalbackin g-ratchets'a; in such manner thatwhen the machineis backing the wheels turn freely upon the axle, but when the machine advances the axle turns with the wheels.

The main frame 0 rests upon the axle, and extends both in front and rear of the drivingwheels, in order to facilitatethe connection of the cutting apparatus.

This main frame is of metal, and is cast with the following parts in one piece: a toolbox, 0, arranged longitudinally on the inner side of the main frame, serves not only to contain tools, but to brace and strengthen the frame, thus admitting of the latter being made thin and light. Directly opposite this toolbox a flange or guard, c, is formed upon the outer edge of the main frame, which thus not only serves to strengthen, but also serves as a" guard or fender to the gearing. Lugs or flanges 0 near the inner front corner of the main frame, serve as a socket for the tongue, .and to strengthen the frameat a point where the greatest strain is applied,an d consequently where the greatest strength is required. On the outer rear corner of the frame half-bearings d are formed, for thereception of a crankshaft, d. The end of the platform may also be strengthened by ribs 0 Half-boxes d are formed on the under side of the main frame, for the reception of the main axle. A stud.-

, shaft, 0, for the reception of an intermediate gear-wheel, e may be applied to the main frame in any suitable manner By thus casting the platform of one piec of metal, I am enabled to obtain a firm support for the. gearing and other parts of the mechanism, and thus preventits binding or straining. I am also enabled to use short shafts for the gear-wheels, and to drive the gearing by means of an inside gear-wheel, 15, applied totheaxle of thetransportingwheels. I

An internally-geared spur-wheel, E, fast on the main axle, drives a spur-pinion, c, and bevel-wheel e on the short shaft 0, which bevel-wheel meshes with a pinion, e, on the crank-shaft d, which drives the cutters by a crank and pitman', in the usual way.

The crank-pin is provided with a ball, f, and a pitman-rod, F, with a corresponding socket, (see Figs. 6 and 7,) thus allowing the cutters to rock and roll freely without straining the pitman.

The inner end of the finger-beam G is rigidly secured to a drag-bar, H, extending upward and forward, and pivoted at its front end to a transverse arm or link-rod, H which is in turn pivoted at its outer end to the outer front corner of the main frame.

The finger-beam is likewise connected with the main frame by means of a lateral brace or coupling-arm, I, pivoted at one end to the drag-bar, near the rear end thereof, and at its other end to the main frame near its outer rear corner. r

The front arm or link-rod H is connected by a link, h, to a crank or elbow lever, H, pivoted to a plate, H, bolted to the inner side of the main frame at or near its front corner, but between the wheels. This plate is constructed in the form of a sector, and the pivot of the lever is concentric therewith, so that its arm can be made to catch between the teeth projecting from said sector, and thus sustain bar allow the finger-beam to vibrate freelyahout their outer joints, so that either end of thefinger-beam may rise orv fall withoutcorrespondingly affecting the other, and the finger-beam may also be rocked or .rolled inthe line of its length. 4

A lifting-lever, J, mounted upon the inner rear corner of the main frame, and provided with a sectoror detent and a spring, such as above described, is connected with the fingerbeam, so that it can be raised bythe attendant while on his seat. This lever is shown in the drawings as provided with a grooved sector, J over which the lifting-chain J passes, the lower end ofthe chain being attached to the coupling-arm l.

When the machine is used as areaper, the rear'lever can be detached, leavingthe forward lever to enable the driver to raise and lower the cutting apparatus together with the front part of the platform, which is secured to the finger-beam in usual well-known ways, and supported upon two caster-wheels. The outer one or grain-wheel is pivoted to a vertical guard-board of the divider, and the inner one, or that next the main frame, is applied to a short beam'secured to the platform near its inner front corner.

. Being thus supported, the platform can be raised or lowered by means of r the front rockinglever-that is'to say, both the inner and outer ends of. the finger-beam, and' the platform, which is secured to it, will be elevated or depressed alike, neither ehd being allowed to sag. The axes of the caster-wheels become the fulcra about whichthe platform is adjusted while cutting grain. 7 .The organization of mechanism above described is especially adapted fornse. in connection with a rake mounted on the inner front corner of the platform, revolving on an axis substantially vertical, and driven from the main'axle by a chain; but, as other raking attachments may be used in conjunction with my machine, I will not here particularly describe the construction ofthe rake, the arms of which are pivoted to a crown-wheel and sweep around over the platform, then rise to a vertical position, and descend again in front of the cutting apparatus, so as to sweep the grain when out around, and deliver it upon the ground. w

It is obvious that a lever for rocking the front end of the drag-bar, arranged outside of the driving-wheel, or in rear of its axis, would be in the way of the rake and its driving mech anism,while a lever arranged transversely across the front-of the main frame would be inconvenient for operation by the driver while in his seat on the machine.

The operation and advantages of my improvements will be obvious to those skilled in the art without further description.

I do not broadly claim rocking the cutting apparatus of a harvester by means of a lever applied to the front end of a drag-bar, as that is not new; but, as far as I am aware, I am 7 the first to organize a mowing-machine with a cutting apparatus to be rocked by a lever pivoted on the main frame, in front of and between the driving-wheels, and moving parallel therewith, which organization afl'ords obvious facilities for manipulation by the driver.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The cast-metal main frame, constructed, substantially as hereinbefore set forth, in one piece, with a tool-box and flanges on its upper surface to strengthen the frame, and with recesses in its outer rear corner for the gearing.

2. In a two-wheeled hinged-bar harvester, the lifting-lever pivoted on the main frame, between the driving wheels, (moving parallel therewith,) and in front of the axle thereof, provided with a detent, and connected with the coupling-link to which the forward end of the drag-bar is attached, these members being arranged and operating in combination,substantially as hereinbefore set forth.

3. The combination, as set forth, in a twowheeled, hinge-bar, rear-cut harvester, of the forward lifting-lever with the rear lifting-lever, each having a separate axis and moving parallel with the wheels, whereby the ordinary adjustment is retained, and the adjustment of the pitch of the guards to suit the condition of the crop to be cut is made instantaneously by the driver from his seat on the machine without stopping it.

4. The combination, substantially as hereinbefore set forth, of two main supporting and driving wheels, a main frame mounted thereon, a finger-beam connected with the main frame by a hinged drag-bar and coupling-arm, a platform connected with said finger-beam and supported upon caster-wheels, and arocking lever mounted upon the main frame and connected with the front end of the drag-bar, whereby the driver from his seat can raise or lower the finger-beam and platform by rocking them on the caster-wheels, without disturbing the parallelism or horizontality of either end of the cutting apparatus.
