4 Claims. (or. 56-21) This invention relates to agricultural machines, and in particular to agricultural machines known as combined harvesting and threshing machines.

The primary object oi the invention is to provide a machine of this character which will 'embody all 01' the characteristics and advantages of the usual large and expensive harvesters and threshers now in common use. The elevating platform is provided with an endless elevator the platform being preferably hinged to the front end of the threshing unit and being substantially the same width as the threshing cylinder and having s. cutter bar on the forward end of the elevator platform which somewhat longer than the width of the elevator and having gathering means for urging the graincut by the extra length of the cutter her inwardly and on the elevator.

An important object of the invention is to provide a combined harvester-thresher which may be operated and controlled by one man, thereby reducing the cost of operation to a minimum.

A still further ObJQCt of the invention is to pivotally mount the platform of the harvester so that the piatforrn may be readily and easily tilted to adjust the cutter bar operating at the forward end oi the platform. with respect to the ground surface and crop being harvested.

Another important object of the invention is to provide agricultural machines of this type wherein the harvester platform is mounted in direct alignment with the threshing cylinder and in front of the threshing cylinder, thereby eliminating the usual elevating canvas feeder and other complicated machinery commonly em ployed in harvester and thresher machines now in use.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise emhodiment of the invention herein disclosed, may be made within the scope of what is claimed.

' without departing from the spirit of the invention. i

Referring to the drawings:

Figure 1 is a side elevational view of a machine constructed in accordance with the invention.

Figure 2 is a plan view thereof.

Figure 3 is a partially sectioned view taken on line 3-3 of Figure 2.

Figure 4 is a sectional view taken on line 4-4 of Figure 2.

Figure 5 is an enlarged sectional view through the bearing and shaft that provide the support for the harvesting platform.

Figure 6 is an enlarged sectional view through the harvester platform bearing taken at right angles to Figure 5.

Referring to the drawings in detail:

The frame of the machine is indicated generah ly by the reference character 5, and is supported on the axle E on which the wheels 1 are mounted.

Mounted on the frame 5 of the machine is preferably a platform 8 which provides a support for the thresher unit a in which the threshing cylinder iii and usual shaker screens of the threshing machine, are mounted.

as clearly shown by Figure of the drawings. the front end of the body portion 9 curved downwardly and upwardly as at l2, the front edge being disposed adjacent the movable harvester platform E3 on which the endless conveyor belt H is mounted. This belt i5 operates over the roller l5 mounted on the shaft l6 which extends transvcrsely of the thresher unit F: and platform i3 and carries the substantially large pulley El atone end thereof. The reference character i8 designates a belt which operates over the pulley i8 mounted on one end of the shaft 23.. This belt i8 also operates over the pulley H and transmits movement of the shaft 23 to the shaft IR and endless convevor belt H.

Mounted on the opposite and oil the shaft 25 is a pulley over which the belt 2| operates. the belt 2i also operating over the pulley 22, secured on the shaft 28, which in turn is operated icy means of the motor 2 and belt 25.

The shaft is is mounted in bearings, indicated by reference character 26, disposed near opposite sides of the front end of thresher unit 9 and plat iorrn l3. Each of these hearings comprise an elongated body portion and an offset supporting section 21, the supporting sections being formed with bolt openings to receive the bolts 27'. Thus it will be seen that due to this construction, the elongated body portions of the bearings are disposed in, spaced relation and they provide surfaces for the metallic straps 28 that are connected with the outer edges of the harvesting platform l3, thereby providing not only a hearing for rotatably supporting the shaft I6 but at the same time pivotally secures platform [3 on platform 8. U-bolts 2B embrace portions of the bearings and extend through openings in the platform 8. the U-bolts contacting with the metallic s raps to prevent movement of the metallic straps longitudinally of the bearings 28.

Mounted on the shaft I6 is a pulley ill over which the belt II operates, the belt 8| also openatlng over the substantially large pulley 32 mounted on one end of the reel shaft 34 whereby the reel 35, mounted on the shaft 84 and operating at the front end of the machine, is rotated to move the grain being cut into the cutter bar of the machine.

The cutter bar is operated by means of the pitrnan 38, which receives its motion through the crank 29 mounted on one end of shaft It, the pitman being connected with the bell-crank lever 31 which in turn connects with the arm 38, extending from one end of the cutter bar sickle.

Thus it will be seen that due to the construction of the bearing 28, the harvester platform and cutter bar may be raised and lowered at the will of the operator while the machine is in motion. Rising from the frame of the machine are posts 39 which posts provide a support for the shaft 39' having levers 4i mounted on the ends thereof, that are connected with the links 42 that in turn connect with the harvester platform at 43. The lever is secured to the shaft 39', near one end thereof for operating the shaft 38. As the lever 40 is operated, the harvester platform is raised or lowered and may be adjusted with respect to the ground surface, for the eflicient operation of the machine.

Curved guards H are provided at each side of the platform. The guards at their front ends register with the overhanging part of the cutter bar. That is, the ends of the part of the cutter bar which extend past the sides of the elevator I! register with the front ends of the guards (see Figure 2). The platform at its front end is made the full length of the cutter bar and having side panels forming a trough, the side panels converg ng inwa dly. The guards 44 occupy the space between these panels and the sides of the elevator. The edges adjacent the elevator must obviously be slightly above the plane of the top of elevator ll so the garin that falls on the guards can move inwardly on the elevator.

It will be noted that the end panels converge to near the sides of the elevator and that the guards terminate at the same points. Therefore, all of the grain, before it reaches cylinder M, will be moved on the elevator and since the cylinder length is about the same as the width of the elevator, the grain will be eased into the cylinder in the best condition for threshing Thus it will be seen that the grain will be urged inwardly by the platform guards as it is carried rearwardly by contact with the grain on the elevator, and it may be urged inwardly by gravity when the guards are sumciently curved in which case the panels and guards cooperate to accomplish the best results.

The tractor hitch is indicated by the reference character 45 and affords means whereby a suitable tractor or other propelling means may be hitched to the machine.

While I have shown and described the motor 21 as the power device of the machine it is to be understood that other well known means for supplying power may be provided. I have shown the details of my device in their preferred form. Clearly many minor changes may be made without departing from the spirit and scope of my invention as recited in the appended claims.

Having thus described the invention, what is claimed is:
