TRACTOR ENGINE.

Application led March 9, 1916.

To @ZZ whom it may concern.'

Be it known that l, Lun W. Mnncnnn, a resident of La Crosse, in the county of La Grosse and State of Wisconsin, have invented certain new and useful improvements in Tractor Enginesy of which the following is a full, clear, and enact description.

rllhis invention rotates to tractors. u

The object of the invention is to iinprove l0 the fran'ie construction, so as to afford a strong and durable structure upon which the engine proper and other working parts can be suitably attached, and give a niechanisrn of sufficient strength at the place of inaxiinuni stress, and be comparatively light and secure in construction.

Another object of the invention is to provide a )nain structure carrying the heavy portion of the load and an extension therefroni in tubular forni for carrying a guide wheel, with means of clamping the tube to the inain structure to prevent rotation of the tube with relation to the inain structure.

Another object of the invention is to provide a lnain france with a tubular strut eX- tending transversely of the structure, with engine sustaining brackets` integral with the strut and extending angularly tothe direction thereof, with means for attaching wheel axles thereto whereby the inain stress of the fraine is carried upon the strut.

ln the drawings: Fig. l is a plan view of the inain frame of the structure. Fig. 2 is a rear view of the main frame. Fig. 3 is a side elevation of the right forward end of the niain fraine with a portion broken away to show the method of holding the tubular extension against rotation. Fig. 4: is a cross section of the tubular portion of the Inain frame on the line e-e of Fig. l with a draw bar and seat bracket attached thereto. Fig. 5 is a detail view of the right side of the franie on the line ZJ- and g--g of Fig. 1 and showing the niethodof attaching a stub axle above the tubular strut of the frame, with portions of the frontend rear engine sustaining brackets. Fig. G is a detail on the line cZ-d of Fig. l, showing` the rear engine bracket, and a sub-bracket for sustaining the transverse engine-driven shaft. Fig. 'l' is a detail on the line z-i of Fig. l, showing a rear view of the right forward end of the inain frame anda rear end view of the extension tube. F ig. 8 is a left side-elevation, showing the left front brackets for sus- Serial No. 83,107.

Fig. 9 is a detail of the forward engine supporting bracket, on the lines c-c. Fig. lOis an elevation of the right hand side of the asseinbled structure, showing exhaust pipes le,.-. ing froin the engine to the tubular extension, and having portions broken away. rr'Ehe right hand driven wheel is omitted frein this view for the sake of clearness in showing the relation of the parts. Fig. 'll is a detail of the niethod for connecting the env liaust pipes to the tubular extension.

At its rear end the hole 23 is provided for receivinga clevis for the attachment o1' a plow or other structure lto be drawn by the tactor. Rigidly attached to each of the extremities of the transverse shaft 6"y is a pinion 2l shown in section only in Fig. 10, haif'ing teeth-meshing in gearings 25, attached toward the peripheries of the sustaining and driven Wheels 26, in which at either side ot the structure are mounted the stub axles 1f), the stub axles beingvthe means by which the `trame'portion of the structure is sustained inthe Wheels.

Above the 3-1`1dfon'the'shank offork'32 is artaclied a sectionot" a worm-wheel Se, gearing with worin 55, which is rigidly allixed to the rod extending baelwardly and provided with a hand wheel not shown, the rear end et the rod 36 being sustained in a brac-liet 3?' suitably attached to the shelf 2L on bracket 2 shownin Figs. 1 and 10.

t is manifest from the above description that the structure described wll a niaxnnum ot strength with r=v a el weight and material, and a structure t iat is compact, readily accessible, and very little liable to breal-zage.
