HARVESTING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 315,901, dated April 14, 1885.
Application filed December 7, 1883. (No model.)
T @513 whom it may concern:
Be it known that I, ROBERT BROWN, a citizen of the United States, and a resident of Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Harvesting Machines, of which the following is a specification.
One of the objects of my invention is to provide a self-binding harvestingmachine hav ing the main frame mounted upon a yoke, and pivoted to the journal-boxes of the drivingwheel axle in such manner as to be readily raised and lowered thereby and also to be tipped or tilted on the main axle by a simple lever movement.
Another object of my invention is to provide a gravitated float which will compress the grain upon the elevator and carry it up in a more satisfactory manner than with the floats now in use, and also to simplify the construction of the float, so as to prevent it from being liable to get out of order.
Another object of my invention is to so construct the drums or rollers which propel the endless carriers that they will not slip or move on the carrier-rolls as the carriers contract or expand by reason of atmospheric changes.
Another object of my invention is to employ a single sprocket-chain, so arranged in combination with the sprocket-wheel as to drive the binding mechanism, cutter-bar, and grain-carriers.
Other objects of my invention will be more fully set forth in the description of the accompanying drawings, in which- Figure 1 is a rear elevation of the driving mechanism of my improved self-binding harvesting-machine. Fig. 2 is an enlarged rear view of the harvester and elevating frames. Fig. 3 is a sectional elevation on line y 3 Fig. at. Fig. 4 is a top or plan view of Fig. 3. Fig. 5 is a grain side elevation of the harvesterframe. Fig. Bis a detailed sectional elevation of the tilting devices. Fig. 7 is a sectional elevation on line at (1 Fig. 6. Fig. Sis afront ele vation of the adj usting-lever catch. Fig. 9 is an inner side elevation of the carrier-float. Fig. 10 is an enlarged detail view of the parts thereof. Fig. 11 is avertical section on line y y, Fig. 5. Fig. 12 is an inverted section on line a: re, Fig. 9.
A represents the driving-wheel upon which the harvester-frame is principally mounted.
B represents the rear sill of the ordinary platform-frame, which is supported at the extreme outer end by an ordinary grainwheel.
O represents the journal-boxes of the driving-axle. They work in ways formed by the segments D D, which are rigidly secured to the side sills, b b, at each end of the drivingaxle. The top of the segments D D are connected by a brace, d".
E represents a yoke the free ends of which pass upon each side of the wheel A, and to which are bolted the ears 6 of the journal-boxes, as shown in Fig. 11.
In order to elevate or depress the main frame of the harvester, I hinge the yoke E to the crank-rod E, which is screw threaded and suitably j ournaled in bearings mounted on rail a and post 0, as shown in Figs. 2 and 5.
F represents a screw collar or nut, which engages with the screw-threads chased on the lower end of the cranlcrod E.
ff represent links, one end of each of which is pivoted to the screw-collar F and the other end to the bracket 9, which is rigidly secured to the yoke E.
In order to depress the frame a Z) c d vertically, the crank-rod E is turned so as to depress the collar F, which carries down the rear end of yoke E, which fulcrums on the main axle, and by means of the links J J lowers the frame, which is secured to the yoke E by' these links, thereby depressing the frame or carrying the sills b nearly to the ground. A reverse movement of the crank-rod E will raise the yoke E on the journal-boxes as a fulcrum and pull up the link J J, and consequently elevate or raise the frame.
It is desirable, also, to tilt the harvesterframe upon the main axle to accommodate itself to the different conditions of grain. This I accomplish by the following mechanism:
G represents the tongue, which is pivoted to the frame by means of rigid brackets G G.
G represents a link pivoted at one end to bracket G and at the other end to the sliding box H, which is mounted and moves on ways H, affixed to the tongue G.
H represents a link, one end of which is pivoted to box H and the other to a pivoted lever, h, whichis pivoted to the standard or bracket h, which is rigidly secured to the tongue G.
I represents an adjusting-rod, with a series of notches cut in its edge, which slides through a mortise cut in bracket I, which is secured to the elevator-frame piece m.
I represents the pin with which the notches in lever I engage to hold the frame in any desired fixed position. By lifting the lever I and pulling it backward the connectingrods h H draw the. sliding box H forward, and with it pulls link G, conveying pressure to bracket G, which depresses the forward end of the harvester-frame, which is swiveled or pivoted upon yoke E by links J, one end of which links is pivoted to the forks of yoke E, and the other end to the framepieces b b. This mode of connecting the main frame tothe yoke E allows the rear end of the latter to be depressed to allow the frame to be lowered vertically, and it also allows the main frame to be tipped or tilted by rocking on the .axle of the driving-wheel. I
The binding apparatus is mounted upon a bracket, J, which is secured to the posts 0 and to side rails, c c.
K represents the main drivinggear of the knotting and binding mechanism. The binding and knotting mechanism is not shown in the drawings, as any well-known binder may be employed.
K represents the sprocket-wheel, journaled upon a bracket, J, on the outer face of which is a gear meshing with the driving-gear K.
K represents a sprocket-wheel journaled upon the end of the crank-shaft, which crankshaft is of ordinary construction, used to drive i the cutter-bar.
L represents the main driving sprocketwheel, which is driven by the ordinary bevelpinion, which is in turn driven by the driving-wheel A. These parts are of the ordinary construction, and are not shown.
L represents an idler-roll journaled upon the frame B.
L represents a sprocket-wheel which is fastened upon the end of the carrier-roller of the platform. This endless platform-carrier is of the ordinary form of construction. It may be either canvas or chain, as desired.
. M represents asprocket-wheel which is journaled upon a stud, M, which is rigidly secured, to one of the side pieces, m, of the elevator-frame.
m represents a gear-wheel keyed upon the stud M, to drive the pinion a, which is keyed upon the end of the endless-carrier shaft N of the floating frame 0.
N represents a sprocket-wheel keyed upon the outer end of the roller P of the elevatingframe. Q represents the endless sprocketchain,- which is driven by the sprocket L, keyed upon a main shaft, and passes in the direct-ion of the arrows'over sprocket L, which drives the horizontal platform-carrier;thence over the sprocket M, which, by means of the spur-gears m it, drives the endless carrier of the float; thence over the sprocket N, which drives the endless carrier of the elevator-frame; thence over the sprocket K driving the binder mechanism; thence over K, which drives the cutter-bar.
The elevating-carriers are constructed as follows: m represents the side pieces of the elevator, which are rigidly secured at one end to the binder-frame and the other to the plat form-frame B. pp represent side guard-strips, which are connected by transverse cross-strips p 19. It represents the canvas carrier or endless belt, which'passes around the driving-roller P at one end, which is suitably journale-d to the frame-pieces m and upon whichrroller is keyed the sprocket-wheel N. A similar carrier-rol1er is mounted loosely, and serves as an idler at the lower end of the frame M, and an endless carrier of canvas is preferably connected around these rollers and provided with the ordinary cross-strips or other means for elevating the grain. This elevator-frame and endless carrier are of the ordinary construction. I employ a gravitated float-elevator, which is formed oftwo pieces, as shown in Figs. 1, 2, 9, 12. It has similar guards p p, and strips 10 p, as shown and described for the carrier, and a similar endless belt, p which is driven by shaft'N, as before described. A similar shaft, 1?, is journaled in the upper end of the frame In order to have the float rise under the pressureof the grain, and yet rest upon it and compress it, so as to bedelivered in a compact mass to thebinder-table, I mount this float so as to automatically fall by gravity and press upon the grain and to be raised or lifted off from the elevator-frame by the upward pressure of the grain and elevator. I accomplish this by connecting the floating frame to the elevator-frame by parallel links S S, placed upon each side at the lower end, the upper end being held from lateral movement by guides t. This upper end may be raised independently of the lower end, and vice versa. These frame-pieces O O m m of the elevator and float frames are connected somewhat after the manner of a parallel rule. connected to the platform, is immovable, and the floating frame is allowed to rise freely by the pressure, as before described, moving on the links S, and as soon as released from the pressure of the grain at either end it will antomatically fall down upon the carrier-frame m. I have found by experience this mode of construction of the floating frame to be very important, and to operate in a better manner than any other form of float in ordinary use.
Great difficulty has been experienced in the use of canvas carriers. Being made of fabric the moisture of the atmosphere causes them to The elevator-frame, being rigidly contract, which often causes them to rip or ble in the use of harvestingmachines, owing to this change of atmosphere. I have found by experience that the difficulties caused by the contraction and expansion of these endless carriers may be chiefly avoided by the following instrumentality: T represents rubber collars or sleeves, one or more of which may be used, and are tightly secured to the drivingshaft of the float, carrier, and elevator, respectively, and form the bearing surfaces over which the canvas is stretched and by means of which it is propelled. The elasticity of these rolls compensates in some degree for the contraction and expansion of the fabric, and the elastic character of the rubber causes a better frictional contact of the endless belt, and prevents to a material extent the slipping of the canvas upon the driving-rollers.
trepresents a side guide on the elevatorframe piece m, for preventing lateral movement of the floating frame.
I claim- 1. In combination with the mainharvesterframe, a yoke, E, hinged to the boxing of the axle at one end, and to the screw-threaded collar F at the other end, working on threaded shaft E, said yoke connected to the main frame by the links J, substantially as described.
2. In combination with the harvester-frame secured to the drive-wheel axle by the yoke E, the segmental standards I) D, screw-threaded shaft E, screw-collar F, and links J J, pivoted to the yoke and the frame, substantially as described.
3. In combination with the main frame A, suspended upon the main drive-wheel axle,
the tilting mechanism I h H G, connected to the forward end of the main frame and to the tongue G,whereby the frame may be tilted upon the main axle, substantially as described.
4:. The combination, with the tongue G, the adjustable sliding box H, attached to and moving on ways H, mounted on the tongue, the link H, connected with said sliding box, the lever h, connected with the link H and fulcrumed upon the tongue, and the rod I, connected with the lever h, substantially as described.
5. The combination, with the driving-wheel K, of the knotting mechanism and the sprocket-wheels K, K, and L, mounted on the main frame, of the sprocket-wheel L, mounted on the platform, and the sprocketwheels M N, on the elevated carrier-frame, and the single chain Q, adapted to drive the knotting mechanism simultaneously with the raking and elevating apparatus, substantially as described.
6. In combination with the stationary carrier-frame at, having the endless apron driven by the chain Q, the gravitating float-frame 0,
