Application filed November 20, 1918. Serial No. 263,322.

To all whom, it may concern: Be it known that 1, JAMES M. HOWE, a citizen of the United States, residing at Cleveland Heights, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Tractors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to a tractor adapted to haul various trailers, farm implements, etc. The invention is particularly concerned with the frame of the tractor, which, while being light and cheap, is very strong and stiff and forms in effect a cantaliver pivoted at the rear or driving axle and adapted, if necessary, to support the entire Weight in front of such axle. To this end I have provided a rear housing for the transmission and differential gearing and having suitable axle sleeves, this housing being preferably a casting, and a separate forward extension secured directly thereto and carrying the engine. This forward extension is of pressed metal construction having as its rear end a bulk head which abuts and is removably connected tothe forward end of the gearing housing. By this means I cheapen and lighten the frame, and am enabled to provide unusual accessibility for the various mechanisms carried. i l

The above mentioned features, and others of advantage, Will be apparent from the illustrative embodiment of my invention shown in the drawings, and the detailed description thereof hereinafter, given. The essential novel characteristics of the invention are summarized in the claims.

In the drawings, Figure 1 is a plan of my tractor; Fig. 2 is a side elevation thereof; Fig. 3 is a sectional plan of a portion of the gear housing and the extension frame, being on a larger scale than Figs. 1 or 2; Fig. 4 is a vertical section of the frame parts shown in Fig. 3; Fig. 5 is a rear endelevation of the extension frame; Fig. 6 is a plan of the extension frame and Fig. 7 is a side elevation of the same, these views being intermediately broken away; Fig. 8 is a plan of the gearing housing and Fig. 9 is a front end elevation of the same looking toward the rear.

Referring first to Fi s. 1 and 2, 1O indicates the rear or gear housing, 11 the axle housings secured to its opposite sides, 12 the ward end pressed metal front extension of the frame abutting and secured to the front end of the gear housing. 13 indicates the rear Wheels, the axles of which, not shown, extend through the housings 11 into the gear frame and are thereconnected through the differential and transmission mechanisms .with the propeller shaft 15. This shaft is connected by a flexible coupling 16 with the intermediate shaft 17, which is connected by a clutch 18 with the fly wheel 19 on the engine shaft. 20 indicates the engine which has lateral arms 23 mounted on brackets 22 carried by the extension frame 12.

The front axle 24 is secured to this extenslon frame 12 by a transverse leaf spring, 29. 25 indicates the front wheels, shown as connected by knuckles with the axle, and 26 and 27 and 28 the steering gear (intermediately broken away from Fig. 1), leading from the steering knuckles tothe steering wheel. 30 indicates brace rods leading from the front axle to a ball and socket joint 31 carried by the extension frame. 32 designates the hood over the engine, 33 thetank for fuel at the rear of this hood, and 34 the seat for the driver. Suitable controlling levers, not shown, are intended to be within easy access from this seat. The drawings show at 35 a belt pulley which may be clutched with the engine and serve to drive any desired machinery when the tractor is stationary.

Referring now more 3 to 9 inclusive, the body of the particularly to Figs. showing the frame in detail, casing 10 is a box-like member (preferably a single integral casting) having side walls and 41, a front wall 42, rear wall 43 and a bottom 44. This casting has on its side walls suitable bosses as 45 and 46 for transverse shafts, external seats 47 for securing the axle housing, internal seats as 48 for carrying the tran mission gearing, and suitable transverse stjfiening ribs 49. There is also a seat 50 (Fig. 9) at the forfor attachment of the housing 52 which carries the bearing for the propeller shaft.

It will be seen that the rear housing described is a self contained structure carrying the differential gearing, the transmission gearing and the gearing to the pulley 35. The gearing itself is not shown. The parts within this rear frame are covered by channel shaped sides 60 and 61, a channel.

shaped front 62, and a .rear end bulk head composed of one or more plates 63, 64. This bulk head is effectively secured to the forward end of the gear housing 10. As shown the securing is effected by cap screws 75 passing through the bulk head into the bosses 58 on the forward face of the. front wall 42 ofthe gear housing.

As shown, the bulk head comprises two transverse plates riveted together, the plate 63 being flanged at its ends as shown at 71 and 7 2 and there riveted to the webs of the side members 60 and 61, and having top and bottom flanges 69 and 70. Suitable gussets 65 are riveted to the top flanges 66 of the side members 60 and 61 and to the top flange 69 on the plate 63. Intermediate gussets 68 are also provided between the plate 64 and the webs of the side beams 60 and 61.

The forward frame is further transversely braced by a sheet metal downwardly-facing trough-like member 80 which is bowed downwardly and carries adjacent to the center a pivot 81 for the forward spring. This member has its end portions outwardly flanged against the webs of the beams 60 and 61 as shown at 83. 84 are gusset plates riv- 86 to the bulk head, being secured to a flange eted to the beam 80 and the flanges 66. Near the rear end of the forward frame is a transverse channel shaped brace 86 (the top flange 85 of which is centrally depressed to clear rotating parts). This .brace is flan ed at its ends and v is riveted to the webs of the side members 60 and 61. A suitable bottom plate 87 extends between the brace 88 at the lower edge of the brace and to the flange 7 O.

It will be seen that the forward frame member is a self-contained structure made of sheet metal and thus light but strong and stiff. Though readily disconnectible from the gear housing it constitutes in practice a rigid extension thereof, adapted to effectively support all of the weight upon it, as well as the axle and front wheels when the forward end of the machinetends to lift from the ground.

As heretofore stated the engine is mounted on brackets 22 carried by the front frame. These brackets are shown as sheet metal stirrups having top portions .90, and downwardly extending arms with lateral projections 91 therefrom which lie beneath the channel flanges 66 and are flanged at their ends at 92, whereby they abut and are riveted to the webs o the channels60i, and 61. The lateral projections 91 also have their upper edges flanged over, as illustrated at 94, these flanged portions extendin beneath and being riveted to the channel anges 66. There being two pairs of these stirrups, four points of support are provided for the engine, which is shown as having its laterally extending arms 23 resting on and secured to these four stirrups. 1

As heretofore stated the cross beam or bolster 80 carries the seat for the forward spring, beneath which is the axle 24. This axle 24 has holes through it, enabling the securing to the axle of the forward ends of the diagonal brace rods 30. The rear ends of these rods join in a fitting 96 which has on its rear end a ball occupying the socket casing 31 heretofore mentioned, which is secured to the cross member 86. The cross bar 86 is further braced to take the thrust from these brace rods by means of the channel shaped trough member 98 riveted to the channel bar 86 and to the bulk head plates 63 and 64.

The front frame it will be seen, is not only strong, stiff and light, but it is largely open to a low convenient access to all of the parts. One of the advantages with my construction is the ease of accessibility. The tank is made readily removable and when it is taken off it exposes the steering gearing, the coupling and the clutch, and these units may be removed without disturbing the motor or necessitating jacks under the frame. The removal of the top plates of the gear housing exposes the differential and transmission gears. By simply abutting the front frame against the rear frame and bolting it thereto, I provide ready separability enabling the machine to be conveniently taken apart for shi ing or repairs.

aving thus described my invention what I claim is 1.
