TRACTOR.

Application' led pril. 7, 1922. Serial No. 550,320.

To all whom z't may concern.:

Be it known that I, GEORGE A. BRYAN, a citizen of the United States, residing at Peru, in the county of Miami and State of Indiana, have invented certain new and useful Improvements in Tractors,'of which the followingis a full, clear, and exact description.

My invention relates to tractors, and has especial reference to means for utilizing the quently t tractor as a stationary powerdevice. It lis customary for this purpose to equip the tractor with a belt ulle which is coupled to the machiner to e riven by a belt. Frelie pulley is on the end of a speclal transverse shaft provided for the purpose, which is either operatively connected to the transmission gearing leading to the differential on the rear axle or has an independent drive connection with the engine. In

although some cases where the shaft is coupled to the transmission gearing it is necessar to raise the rear wheels from the ground when using the tractor as a `.stationary power device, it has been proposed to provide means for alternately coupling the rst gear of the transmission train with the pulley shaft drive and with the rest of the transmission train.

In accordance with my invention, I simplify this construction by employing a counter shaft adapted to receive and hold a ulley on one projecting end and properly ooated to drive the fan through gearing or l and this counter shaft has permanendrive connection with the transmission gearing in advance of disabling means provided to interrupt the connection -with the differential.

My invention also comprehends other features-,of construction and details and ar-.. rangement of partsas will hereinafter more" fully appear. I shall now describe the illus trated embodiment of my invention and shall thereafter point out my invention in claims. 4

Fig. 1 is a plan of a tractor embodying my invention;`

Fig. 2 is a side elevation of the same;

Fig. 3 is a front end elevation of the frame :fand pulley shaft and housing support there- Fig. 4 is an enlarged sectional plan of the 'parts at the pulley end of the shaft.

The illustrated tractor is steam propelled following generally the design of the vehicle illustrated in my co-pendingy application, Serial No.` 535,167, filed Februa 9, 1922. Mounted on the front end of the ghassis frame is a suitable steam generator 1 in front of which is a condenser' 2. In the rear of the steam generator is the steam engine 3 and on the rear axlesuitably supported on the chassis frame is the transmission gear case 4. The engine shaft 5 extends transversely of the frame and is supported in the rsplined a pinion 9 which isrshiftable into and out of mesh with the spur gear Vwheel 10 on shaft 11, also journalled in bearings in the case 4 in rear of the shaft 8. A pinion 12 on shaft 11 meshes with gear wheel 13 on the rear axle which is connected to any suitable type' of diiferential. It is, therefore, apparent that the transmission train connectin the engine shaft with the rear axle may e disabled by shifting the gear 9.

Secured to the left side of the transmission gear case4 is a ear box 14. The stub shaft 8 extends into t is gearbox 14 and has on its end a bevel gear 15 meshing with a bevel gear 15 on la longitudinally extending stub shaft 16. This stub shaft 16 is connected to and drives a universally jointed, longitudinally extending shaft 17, the frontend of which is coupled to a stub shaft 18 in a gear box 19 at the front end of the tractor.

The transverse fan drive and pulley shaft 20 which bears at its one end in the gear box els 19 is supported in the space between the' boiler l andthe condenser 2 in the manner illustrated in Figures 2 and 3. Connecting the frontk ends of the side frame members' 21 and 22 is a frame front bracket 23 which is pinned at its central point to the front axle 24, and has at its ends two forwardly projecting

arms

25 and 26 on which the condenser 2 is supported. Secured to the top of this. frame front bracket 23 is a pulley shaft housing support 27 on the one end of which is supported the gear box 19 and on the opposite end of which' is supported the bearing 28 for the opposite vend of the pulley shaft. Midway between the gear box 19 and the bearing 28 is supported a fan drive gear box 29.

A bevel gear 3() on the stub shaft 18 meshes with a bevel gear 31 on the end of the pulley shaft in the gear box 19. Spiral gears in the'fan drive gear box 29 serve to drive the stub `shaft 32 on the front end of which is secured a fan 33.

The end of the shaft 20 which projects beyond the bearing 28 is adapted to receive and rotate the belt pulley 34. The end of the shaft has two reductions in diameter, the first reduction forming a shoulder 35, and the extreme end of the shaft is screw threaded. Surrounding the second reduced portion of the shaft is a sleeve 36, the outer end of which is screw threadednnd which has a circumferential flange 37. A nut 38 on the threaded end of the shaft 20 clamps the sleeve 36 and a bushing 36a on the first reduced portion tightly against the shoulder 35, thus locking the sleeve and shaft together against relative rotation, although other well-known means of non-rotatively ,securing the sleeve on the shaft may be employed.

The pulley 34 has a central flat hub portion which fits over the sleeve 36 and bears against the ange 37. Suitable means for locking the two together against relative rotation are employed, in this case studs 38a being used for lthe purpose. The studs are carried by one of the members, preferably the flange, and the other member, in this case the hub, is provided with properly spaced holes to receive the studs. A nut 39 on the screw threaded end of the sleeve 36 locks the pulley in place.

By these means the pulley may easily be put on or removed. If desired, a suitable cap may cover the exposed end of the shaft when the pulley is removed. It is obvious that various modifications may be made in the construction shown in the drawings and above particularly described within the principle and scope of the invention.

I claim:

1. In a tractor having la rear axle, an engine the shaft of which extends transversely of the tractor, an interruptable drive connection between the engine shaft and rear axle, a power shaft extending longitudinally of the tractor and connected with the transverse engine shaft to be driven thereby, a
