Application filed June 13, 1884. Serial No. 134,776. (No model.) Patented ill Canada February 25, 1885, No. 21,150.

To all whom, it may concern.'

Be it known that I, SAMUEL D. MADDIN, a citizen of the United States, residing at Miamisburg, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Harvesters, of which the following is a specification.

My invention is a harvester constructed, as fully set forth hereinafter, so as to connect the platform-frame securely with the main wheel-frame, yet permit its ready vertical and angular adjustment without injuriously interfering with the connections between the driving-shaft and the cutter-bar or the said shaft and elevating appliances. rlhe construction whereby these and other advantageous results are secured is illustrated in the accompanying drawings, in whichv Figure l is a front elevation of my improved harvester. Fig. 2 is a plan view, the elevator being detached. Fig. 3 is a sectional view illustrating the construction of the elevater, and Fig. -l is a plan view ot' the elevator.

There are three frames in the machine-viz., the main wheel-frame A, platform-frame A', and connecting intermediate frame, O-the main wheel-frame A being' supported by the wheels B 13' each of which is a driving-wheel, and connected in the usual manner by ratchets to the revolving axle u, so that either wheel can turn backward without turn ing the axle.

The platform-frame A is jointed to the intermediate conneeting-frame, O, at the outer end of said frame C, the inner end of the intermediate frame being hung to the main wheel-frame A near the stubble side thereof, the pivot-points being in line with a shaft, b, which turns in bearings upon the main wheelframe, and is driven by the revolution of the Aaxle a through the medium of the cog-wheel c upon the axle, a pinion, d, upon a shaft, e, Carried by the main wheel-frame A, and bevelgears ff arranged as shown in dotted lines, Fig. 2, the shafts e and l) being supported in bearings in a closed case, D, which also covers the bevel-gears f f rl`he intermediate frame, O, consists of front and rear-bars, g g', and a cross-bar, gand it projects grainward beyond the wheel B. The

platform-frame A is pivoted to the intermediate frame, O, by the shaft h,which carries one 0f the rollers E, which support the carrying-belt F, so that the platform-frame A' may swing upon its joint without slacking the belt.

The cutter-bar G is connected bya pitman, G', to the wrist of a crank-wheel, G2, upon the end of the shaft b, and as the intermediate frame, C, is pivoted to said shaft any change in the position of said intermediate frame, O, will not affect the movements of the cutter-bar.

The outer end of the platform-frame A is supported by a grain-wheel, H, carried by a lever, H', pivoted to the platform-frame, and a chain or other flexible connection, j, extends from the rear end of the lever H' to a handlever, H2, upon a shaft, 7c3, on the main wheelframe, having arms k 7e', which are connected by links k2 to the intermediate frame, C.

The drivers seat ki is arranged upon a support near the rear stubble corner of the main wheel-frame A, and the lever H2 is accessible therefrom and can be manipulated so as to raise or lower the inner end of the intermediwith the lever H simultaneously raise or lower the grain end of the platform-frame A', whereby the cutters may be elevated to any desired position, yet maintained parallel with the surface of the ground.

It will be seen that this adjustment of the platform or cutter frame A' is effected with- 'out in any way altering the position of the main wheel-frame A, which is steadily supported by the wheels B VB', and that the connection between the main wheel-frame A and the platform-frame A', while permitting the vertical adjustment of the latter, is a Very rigid one, so that the platform-frame A' will not yield or spring out of position in respect to the other parts of the apparatus, and that the adjustment of the platform-frame A' to any desired extent does not interfere with the operation of the cutters. It will also be seen that the platform-frame A' may be elevat-ed to nearly a vertical position Without disarranging its connections with the other parts of the apparatus.

'The pole I is pivoted to the main wheelframe A at a point, 03, near its support upon ate frame, O, and also through its connection IOO the axle a, and a hand-lever, Il, is connected, by a shaft, Il, crank-arm Il, and link l, to a :rearward extension. of the said pole, so that the driver, by manipulating the lever llt, can rock the main wheel-frame A upon its axle, and thereby rock all the frames to any desired extent to alter the tilt or angle of the cutters in respect to the ground. It will of course be understood that the levers 112 I l'l are provided with the usual appliances for holding them in any position to which they may be adjusted. By this construction and arrangement of parts the driver by manipulating but two levers can both rock and raise the platform A,which is maintained parallel with the ground,while the main wheel-frame A is wholly relieved of the weight of the platform-frame A.

I do not limit myself to the use of the special arrangement ot' levers and conneeti ons shown, as itwill be obvious that other equivalent means may be employed for effecting the same result.

there the machine is large and it isdesirable to increase the rigidity of the intermediate frame, C, braces d d may extend from a point upon the frame A near the axis ofthe shaft b diagonally toward the outer corners of the intermediate frame, C.

The main wheel-frame A is provided with supports or standards m m', forming a part thereof for the binder, so that the weight of said binder is wholly carried by said frame and the drivingavheels, thereby imparting an increased traction to the said wheels without increasing the drag upon the other parts of the machine. inasmuch as the main wheelframe A is centrally mounted and rocks upon the axle, the placing of the binder thereon relieves the operator of the necessity of lifting' the binder when adjusting the platformframe, as is necessary in ordinary construction, and it also enables him to make the adjusting-frames much lighter in weight and less costly than when the binder is connected to such parts.

By placing the drivers seat la, the shaft l) and connections therewith, and the pivots of the intermediate frame, (j, adjacent to the outside wheel, l, I throw upon said wheel a weight which is practically equal to the weight of the binder, the heaviest part of which, together with the weight of the pole and of the elevators, arranged as hereinafter described, is of necessity ad jacent to the wheel B.

Heretofore the pole has been placed as near as possible to the line of draft, generally between the drive-wheel and the grain-wheel, so as to overcome side draft, necessitating the placing of thc inner end of the cutter a considerable distance to the outside of the pole to allow space for the draft-horse out from the standing grain.

I place' the pole I in a posit-ion about midway of the length of the intermediate frame, E, and connect the doubletree K to a sleeve or bearing, sliding upon the pole, and I extend from the 4sleeve J a chain, K2, to any one of a series of eyes, n, upon the forward part of the intermediate frame, C, a hook at the end of the chain permitting a connection to be made with any eye. 'hile the pole maintains the position of the team opposite that portion of the machine which is outside of the standing grain, the chain-connection- K2 permits the draft to be actually brought upon a point of the machine at a distance from the pole and more nearly midway between the extreme points of resistance, and the adjustable connection of the chain with the machine permits the line of draft to be varied as circumstances may render necessary. 3y this construction I not only avoid any increase of the length of any portion of the iframe for the purpose of balancing the apparatus, but also tend to cause the draft to lift the fore part of the frame, counteraeting the tendency of the pewerwheels to depress it.

As the binder is outside of the driving wheel l', it is necessary to elevate the grain from the carrier-belt F to the binder over the said wheel l, and to do this without interfering with the free adjustments of the parts, either in operating or transporting the machine,l make use of a jointed elevator-frame,

l will now describe.

The elevator which delivers the cut grain from the grain-platform over the wheel B to the binder devices consists, essentially, of two frames, L and L3, jointed or connected to each other, the former of which is substantially horizontal and extends across the top of the wheel B,beinghinged at its outer end to the stai'idards m, rising from the main wheelframe, while the other one, which is inclined, is secured at its lower end to ears q on the intermediate frame adjacent to the inner end of the grain-platform. The frame L carries three rollers, M M Q, the shaft of the former being concentric with the joint between the frame L and the standards m', and around the rollers M M extends an apron, N. The lower elevator-belt, l?, is carried by two rollers, Q Q, the shafts of which are concentric with the upper and lower joints of the frame L3,

. and the upper elevator-belt, P which is parallel to the belt P, is carried by rollers R R', the shafts of which turn in the upper frame, I i', connected by links L2 to the lower frame, L3, as shown. The shaft o' of the roller M carries at its front end a sprocket-wheel, s, around which a chain or band passes to a sprocket-wheel, s', upon the crank-shaft i), and the shafts of both rollers M Q are connected by an endless chain, t, passing around sprockets, as shown in dotted lines in Fig. l and full lines `in Fig. 4t'. The shafts of the rollers Q R have gears u u?, with long teeth, so that they will remain interlocked, notwithstandingpossible change in the positions of the frames L3 L.

It will be seen that the elevator-frame thus constructed and connected to the main wheel IOO IIO

and intermediate frames will accommodate itself to the varying positions of these frames without throwing the parts out of connection.

rlhe upper eleif'ator-belt, P', may be carried by friction with the grain, or it maybe driven positively by gearing together either of the parallel rollers Q R or Q R', and the roller E is driven by a chain, fn, from a sprocketwheel upon the shaft of the roller Q. By this connection of rollers and driving-chains positive movements are imparted to all the driving-belts in time with each other and without any variation resulting f rom the varying positions of the frames.

It will be seen that in a machine constructed as above described the adj ust-ment of the platform or cutter frame and the operation of the cutters will be in no way in juriously atfected by the fact that the main wheel-frame is passing over uneven ground and t-hat one or the other of the driving-wheels is thereby elevated.

It will be seen that the rollers of the elevatorv are all geared upon the Vfront ends of the shafts, whereby the grain which is carried between the belts is permitted to extend at the rear beyond the elevator. I am thus enabled to carry up grain of any length, the butts only being compressed and the heads extending beyond the belt-frames.

I have not shown a reel; but one will of course be employed.

The elevation ot' the platform-frame A to or beyond a vertical position can be effected, asthe elevator-frame will swing upward and backward to a sufficient extent upon its pivotal points. rlhis permit-s the machine to be moved with facility over ordinary roads and bridges and through narrow gateways.

I do not limit myself to the precise construction shown of the main wheel and intermediate frames, as the construction of the main wheel-frame A will depend to a certain extent upon the character ot' the binder, and the construction of the intermediate frame,

C, will vary more or less with that of the main wheel-frame A; nor do I limit myself to the use ot' an elevator of the charactershown, although an elevator composed of jointed frames connected both to the intermediate frame, C, and the main frame A can be most advantageously employed in the construction of apparatus shown. It will be understood thatthe binder is driven from one of the shafts of the machine, preferably from the crank-shaft Z), which is provided with a dri ving-wheel, fw, :for the purpose.

\Vithout. limitingl myself to the precise coustruction and arrangement of parts shown, I claiml. The combination of the main wheelframe, a pivoted platform-frame extending laterally beyond the main,` wheel-frame, an intermediate pivoted conneeting-frame, and an elevator consisting of two iframes, each supporting a grain-conveying belt, and one frame being upwardly and outwardly inclined and hinged to the intermediate frame near the inner end of the grain-platformand jointed at its upper end to the other frame, which is arranged substantially horizontally and is jointed to standards upon the main wheel-frame, substantially as described.

2. The combination of the main wheelframe supported by' two wheels, a pivoted platform-frame extending laterally beyond the main wheel-frame, an intermediate frame pivoted to the wheel-'frame and extending laterally in :front and rear of one of the supporting-wheels, and an elevator consisting of two parts ort'rames jointed together and one hinged to standards upon the main wheeltrame and the other to the said intermediate frame, substantially as described.

3. The combiliation, with a main wheelframe supported upon driving-wheels, a platform-frame, and an intermediate frame pivoted at its opposite ends to said main and platform frames, of an elevator composed of two frames jointed together and one hinged to the main wheel-frame and the other to the intermediate frame, rollers journaled in said trames and provided at their forward ends with driving-wheels, a driving-belt'between the said wheels, and elevator-belts mounted upon said rollers, substantially as described.

4t. The combination, with the main wheelframe supported by two wheels and the grainplatforni trame, of the grain-elevator, which delivers the cut grain Afrom the grain-platform over the inner wheel, consisting of a substaiitially-horizontal frame, L, hinged to supports on the main wheel-frame,an inclined elevatii1g-'frame, L3, pivoted at its upper end to the frame L and supported at its lower end adjacent. to the graili-platform, and the upper belt-iframe, L', hinged by links to the frame L3, substantially as described.

5. The combination of the main wheelframe, its supportiiig-wheels, the platformtrame in lateral alignment with said main wheel-frame and intermediate frame connecting said main wheel and platform frames and extending laterally in `front and rear of one of the siipporting-wheels, the jointed elevator composed ot' frames L L, the frame Ls being connected at its lower end to said intermediate frame, the frame L being hinged to supports on the main wheel-f ame, and the upperbeltframe, L', connected to the trame L3 of the jointed elevator by links whereby to move indepcndentof said jointed elevator, and whereby, also, both frames forming the elevator are moved toward the main wheel-frame when the platform-frame is raised, substantially as described. y
