Specification of Letters Patent.

Patented Oct; 1920.

Application filed March 22, 1320. Serial No. 367,936.

T 0 all whom it may concern:

Be it known that I, ARTHUR C. MASON, a citizen of the United States, and resident of Flint, Genesee county, State of Michigan, have invented certain new and useful Improvements in Tractors, of which the following is a specification.

The present invention relates to tractors and other self propelled vehicles or apparatus, its objects being to provide a strong and inexpensive mounting for the frame upon the front axle, to reduce the cost of the front end construction of the frame, and

to support the radiator in such manner as to provide increased radiating area without increasing the height or width.

In the drawings, Figure 1 is a front view showing a preferred embodiment of the invention.

Fig. 2 is a fragmentary side elevation, parts being broken away.

Fig. 3 is an enlarged fragmentary view similar to Fig. 2 showing the relation of the radiator support, the lower header, and the cranking lever.

The front wheels which may be of any desired construction are attached to the front axle 2 in the usual way. The frame of the vehicle is made up primarily from the engine casing (which comprises the upper section 4 and the lower section 5 bolted thereto) and a transmission casing, not shown, that extends back to the rear axle; and the crankshaft 6 is carried at its forward end in a suitable bearing 7 and projects therefrom as indicated at 8 to receive the gear 9 which may be utilized to drive a second gear 10 for driving a magneto or other element.

The engine casing might of course extend forward to envelop these gears, but in order to simplify the casting operation it is preferred to employ for this purpose a separate ring or block-like element 12 bolted to the remainder of the casing as indicated at 13, and also to form the closure or cover 14 for the front end of the gear chamber separate from the element 12 and integral with a forwardly extending shelf or radiator support 15 having a depending flange 16 spaced from the element 12 sufiiciently to receive the axle 2. By forming suitable bearings in the parts 1216 for a pin 18 which passes through a bushing 19 in the axle and is held in place by a cotter pin, astrong and readily assembled pivotal connection is made.

Keyed on the projecting end portion 8 of the crank shaft, forwardly of the cover 14, is a fan pulley 20 and forwardly of the latter the shaft has secured thereto suitable clutch jaws 21 adapted to be engaged by a corresponding pin 22 on the end of the cranking shaft 23. As best indicated in Fig. 8, the shaft 23 is mounted to slide rear'wardly and to turn in a bearing 24 formed with and extending through the lower section or header 25 of the radiator, a spring 26 normally holding the shaft at the forward limit of its movement. Thus the shelf 15 may be positioned below the crank shaft, thereby affording additional radiator space without increasing the height.

It will be evident that the actual construction of the several details involved may be varied considerably and to some extent regardless of one another without departing from the spirit of the invention.

I claim 1- l. A self propelled vehicle comprising a frame including an engine casing construction embodying a radiator support having a downward extension, and a front axle piv oted to swing vertically between said extension and a portion of said casing adja-,

cent to but separate from said support.

2. A self propelled vehicle comprising a frame including an engine casing construction embodying a detachable radiator support having a downward extension, a front axle positioned between said extension and the remainder of said casing construction and a pivot passing through the axle and having its ends received in said extension and in the remainder of said casing construction.

3. A self propelled vehicle comprising a frame including an engine casing construction embodying a detachable gear housing and a detachable radiator support that forms a front cover therefor, said support having a downward extension, and a front axle positioned between said gear housing and said extension, and pivoted to swing vertically in respect to said frame.

4. A self propelled vehicle comprising a frame including an engine casing, a cover for the front end of said casing having a downward extension spaced from the adjoining portion of said frame, a front axle received between said extension and said adjoining portion and connected thereto for vertical swinging movement.

5. In a self propelled vehicle, an internal combustion engine casing having a detachable cover at its front end, a radiator for the engine mounted on said cover, and a cranking shaft for said engine passing through said radiator.

6. In a self propelled vehicle, an engine includin a casing having a detachable cover at its front end, said cover having a forward extension forming a radiator support, a radiator mounted on said extension, said radiator including a lower header, and a cranking shaft for said engine passing through said header.

7. In a self propelled vehicle, an engine including a casing having a detachable cover at its front end, said cover having a forward extension forming a radiator support, a radiator mounted on said extension, said radiator including a loWerheader, a cranking shaft for said engine, part of said header being at a lower level than the cranking shaft.

In testimony whereof I aifix my signature.

ARTHUR C. MASON.
