JOIIN F. STEVARD, OF CHICAGO, ILLINOIS` HARVESTER-TRUCK.

SPECFCATION forming part 0f Letters Patent N0. 676,780, dated June 18, 1901.

Application iiled March 26, 1900. Serial No. 10,225. (Nomodel.)

To all whom, t may concern:

Be it known that I, JOHN F. STEWARD, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Harvester-Trucks, of which the following is a full description, reference being had to the accompanying drawings, in Which- Figure l is a plan View of so much of the framework of a harvesting-machine and its supporting-wheel as is necessary to show my invention. Fig. 2 is a sectional stubble side elevation. Fig. 3 is a detail, and Fig. 4 a side elevation,showin g the machine in dotted lines mounted upon the truck. Figs. 5, 6, and 7 are details.

In the drawings, A A A A represent the main-wheel frame of aself-bindingharvester, and B the supporting-wheel.

C and C are the truck-wheels, and D and D the stub-axles.

E is the draw-iron of the harvesting-machine, suitably secured to the main-wheel frame. To this the tongue is attached. This draW-ironE is provided with a hole, preferably angular, as shown in Fig. 7. Upon the main frame, adjacent to the usual quadrant F, is the hanger d. Through the square hole in E the bent stub-axle D' is passed, and its rear end, somewhatreduced, is thrustinto the opening d in the hanger d. The opening d is of suitable width to admit the end of the axle to the position shown in Fig. 3, but not of sufficient height to allow the axle to pass any farther than to cause the angle dE to strike it. The extremeV end of the axle is made to hook downwardly, as at When the Weight of the machine is broughtv upon the axle D', the notch formed between the hook d3 and the shoulder d2 prevents any effort to withdraw the axle from its position; but when the machine is in the position shown in Fig. 2, with the main supporting-wheel upon the ground and the truck- Wheels raised to the dotted line, the axle may be removed by simply pulling it. In rear of the main- Wheel quadrant F is the hanger d4, and secured to the rear of the main supportingframe is the bracket E', havingasquare hole like the hole in the draw-iron E, which may also be regarded for the purposes of this invention as a bracket having a similar function to E'. Through the bracket Er and into the hanger d4 the axle Dis thrust and sustained in precisely the same manner as the one previously described. The axles are pref= erably alike and transportable. Upon the main axle is the usual Worin-Wheel, and in proper relation thereto is a suitable Worm having the shaft G, upon which is the crank G. The truck is applied in the usual inanner-that is, by raising the harvesting-machine high upon the supporting-axle, thrusting the truck-axles to place, and then raising the main supporting-Wheel to the posi tion shown in dotted lines in Fig. 2. This last act puts the Weight of the heavier end of the machine upon the truck-Wheels, and with the tongue attached to the grain-receiving platform, as shown in dotted lines in Fig. 4, the machine is ready for the road.

In the present instance the axle D is shown placed at an angle for the purpose of escaping various parts of the mechanism of the harvesting-machine not necessary to describe. In the usual trucks having short axles secured to the front and rear of the harvesting machine frame it is customary to have a part applied to the frame that can reach well down from the framework into which the axles are thrust. This I find to be objectionable, as any such down-hangers approach too near to the ground. It will be seen that I avoid these objections by bending the axle to a Z shape. Thus bent it is of course necessary to provide `against its turning in its supports. In order to accomplish the latter, I make the axle of a square bar and permit it to fit closely in the correspondingly squared sockets.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination with a harvester, of hangers secured to the frame, and having angular sockets and truck-axles made angular in cross-section, and passing through the hangers, said axles being detachably connected to said hangers.

2. The combination with a harvester, of hangers secu red to the frame, and having angular sockets and truck-axles detachably connected to and supported by the hangers, said axles having their wheels hung on arms de pending below the hangers.

IOO

4:. The combination with the frame of a harvester, of the bracket E', having an angu- I5 lar socket, the hanger d4, and the truck-axle D, said axle having a hook at its inner end to engage the hanger d4, and being also angular in cross-section t0 lit the socket in the bracket E', and carrying its wheel on an arm 2o depending below the harvester-frame.
