The present invention "relates to improvements in tractors of thetype shown in the patent to Eason and Hendrickson No. 1,205,- 98:2, granted November 28, 1916, in whi'c'hthe main frame of the machine comprises a trough shaped shell :in and on which are mounted the engine, transmission, difieren' supplemented and closed at'its rearend by a cast metal rear axle housing'which is-open to the shell. The'engine block and the transmission frame casting are mounted .on the edges of the trough or shell'and are formed with webs cooperating with transverse partition's in the trough to form lubricating chambrs for the'engine and for the transmission,

erence character wherever it occurs in the differential and rear axle driving mechanisms. The IIlV'QlfltlOIl COIIIPIISGS improved power take-offs, an impr'oved" rear axle hous ing and structure, and other :features 'of inventionwhich willfappe'ar from the ,fo1low ing description and c'laims. jIt, is to beunderstood, however, that the detailed disclosure is for the purposeofexernp-lificationonlyand that the scope of the invention is defined in the claimsin whichI have endeavored to distin'guish it from the prior art soj far as known to me without, however, relinquishing or abandoning anyport on or feature thereof.

"A frontcasti-ng-23- projects *into an closes the front end of the shell 20 and is riveted thereto at24, the frontwheels 22 being mounted in the usual manner thereon so that they may be turned for steering the tractor, steering means connected to a. steering 1 a thebottom i'nclines downwardly tram mm F1 g. 4 1s a top plan of the same portion of.

to'rear. Therear edge oftlie-trou h is formed with anloutwardly projecting ange 26by tit by suitable cover plates, are provided at convenient points for access to the interior, and a notch 28 isformed in the edge of the left hand wall for a purpose which will appear. At proper points to divide the oil-containing lubricating chambers from the other. ortions of the shell, the latter is provided wit transverse partitions 29, 30, 31 which may be Welded or otherwise secured to the shell to make an oil tight joint. The upper edges of the respective partitions are cut out in V- shape, as shown in Fig. 7 with reference to partition 31, to coact with'webs formed on the end crank shaft bearing brackets of the engine block and transmission casting to form sealed, oil proof and dust proof lubricating chambers as will presently appear. Splash pans 33 are mounted at proper positions between the partitions 29 and 30 and on bars 34 to cooperate in the usual way with the connecting rods of the engine to provide splash lubrication. A sump 35 communicating with the interior of the shell through an opening 36 receives oil from the pool 37 in the housing and a pump (not shown) which may be of ordinary lubricating type and connected fordriving to the crank shaft, draws oil from the sump and distributes it to the worklng part of the engine and to the splash pans in a well known and obvious manner.

Except in the respects hereinafter noted, the engine may be of a known or preferred type. The base of the engine block is formed with parallel depending flanges 38 to fit within the upper edges of the trough and outwardly extending flanges 39 designed to rest upon the respective edges of the walls thereof. The engine block casting is securedin position on the walls by bolts extending through the bolt holes 40, 41 in the shell and casting,

respectively. The engine block casting also comprises a rearward extension 42 covering the fly wheel 43 and formed with a flange 44 for bolting to a similar flange 45 on the ,transmission frame casting. It will be noted that the partition 30 is so placed that the flywheel is located outside the crank shaft chamber so that the clutch associated with the fly wheel is protected from oil. As usual, the chank shaft is carried in bearings supported in brackets formed with and depending from the engine block casting and the end brackets are formed with webs 46, 47, referred to above, to supplement said partitions 29, 30,

.respectively, to enclosethe crank chamber.

As the construction of these webs is similar to that of web 48 on the transmission frame casting cooperating with partition 31, and illustrated in Figs. 3, 6 and 7 it is suflicient .to show the latter in detail. Each of these webs is formed on its under V-shaped edge with a. channehsuch as 49, to receive its respective partition and a packing 5O surrounding the edge of the partition within the channel.

engine shaft, the transmission and the differential. These several parts and mechanism, except as hereinafter described, are or may be of usual or well known form and are so shown. Specific description is therefore unnecessary. The stub shaft connected to the driven member of the clutch 64 is journaled in a ball bearing 61 supported in a hollow boss 62 formed integral with the web 48 and with the body of the transmission frame casting. The opening of said boss is closed by a cap 63 bolted to the boss and suitably packed to render the joint oiland dust-proof and through which the stub shaft 60 extends. The clutch is shown, as of usual form, at (34, the clutch shifting sleeve at 65 and the clutch fork at 66. The latter is mounted on a squared shaft 67 journaled in brackets on the transmission frame casting and is accessible through an opening 68 normally covered by cover 69. The shaft is or may be turned through the usual connections and hand lever.

The end of stub shaft 60 remote from the clutch and on the otherside of partition 81 and web 48 therefrom, carries a bevel gear 7 O which'isin mesh with the bevel gear 71, shown in F ig. 3 as partially broken away, the. latter being fixed upon the transverse shaft 72, see also Figs. 4 and 5. Shaft 72 is the usual sliding gear shaft of the transmission mechanism. It is j ournaled at its end in bearings mounted respectively in bosses 7374 of the transmission frame casting, see Figs. 5 and 9. The bearing in boss 78 comprises a cup 75 containing a conical roller bearing of novel construction. The cylindrical wall of the cup extends beyond the bot-tom thereof as at 76 and is exteriorly threaded and, interiorly grooved at 77, see also Fig. 12. The bottom of the cup is formed at 78 with a kerf or the like for the reception of a tool for turning the cup to adjust the bearing. The wall of the shell is perforated at 79 for the insertion of the turning tool, the opening being normally closed by a plug. A threaded bolt 80 extends through the shell in position to engage one of the grooves of the cup to lock it in adjusted position. The bearing in boss 74 comprises a somewhat similar cup 75 threaded into said boss and containing a similar roller bearing. Shaft 72 extend.

asagna witha hole forthe shaft is'removably bolted over the notch :28to exclude dust ond dirt;

The transmission mechanism is, :as beforestated, of a well-known type and need not 'herefore. be specifically described. It includes the slidinggears -'86 on the .abovementioned transverse shaft 72, the reversing gear87 andtheduplex or two-diameterigear 88 of the differential with :which thexfirstmentioned gears mesh according to their :position, see .Fig. 4. J The usual gear shifting mechanism is provided ifor operating the shifting gears. Theaduplex gear :88 :through the usual differential gearing comprising bevel pinions 89 thereon and bevel gears 90,

of which one is shown in Fig.v 3, drive the countershafts 91, '92. Shafts 91,-92 are journaled respectively in brackets 93-914 of theltransmission frame castingsand carry,

respectively, gears 95 -96 which are in mesh with master gears? 9798, respectively,

mounted on the rear wheel axles.

The housingon which the rear wheel'axles are journaled and which encloses said master gears, comprises an upper casting 101 and a lower casting 102, said castings being formed 1 at their respective meeting edges withiflanges 103, 104 by which they are bolted together.

At :their front edges these castings are likewise flanged at105: and 106, respectively, and the flanges are bolted to the flange 26 above mentioned on the rear end of the shell and a flange 107 on the transmission frame casting. Referring, .moreparticularly, to Figs. 2, 3 and :8, it will be seen that the castings. 101-102.are formed at their meeting edges I with semi-circular recesses 110-3111 together forming circular openings .which are surrounded by flat fsea-tsfll12, see particularly Fig. 2. To the respective opposite seats are bolted bosses cor. sleeves 113"1 14, through which extend the respective wheel axles 115116. At 'the outer end ofeach sl'eeve is mounted a roller bearing 117 in which the corresponding wheel axle is journaled. The

inner ends of the respective axles are jourhialed in roller bearing 118 mounted in a bracket 119 formed integralwith andazrisin'g from the bottom of'the lower housing cast- 111g.

tially in the main body of the bracket .and partially in said strap. The-wheel axles are thus provided with widely spaced bearings tofirmly support them in proper position. The master gears 97-98 are keyed upon the reparatus while-the latter is being hauled bythe The bracket comprises astrap 120 boltedto thermain body thereofpthe seat for the bearing above mentioned beingv formed parit is not desired to use therearpbwer'take-off above referred to, meshes with said gear 125, see Figsfi and 7. A gear 126is:mounted in a. separate frame or support 127 in the nature of a casting extendingthrough an opening 128 formed inthe transmission frame casting for the purpose and bolted to the latter at 129. The auxiliary casting 127 comprises brackets 130 141 extending downwardly from the snpporting plate of the casting 127 and formed with bosses 132133, respectively, in which arecylindrical seats 134-135. Rollerbea-rings 1364137 a e mounted inthe respective seats and carry a sleeve 138. A collar 139 surrounds the sleeve intermediate the bearingand'is keyed thereto and also to the gear 126,above mentioned. The sleeve is of somewhat larger diameter at its intermediate collar-receiving portion than toward the end where the inner races ofthe bearings are seated so that the latter are properly spaced by the enlarged intermediate portions.

1 shaft 146'to' be now described.

Power take-01f shaft14i6 extends rearwardly through the transmission and rear axle lrousing andthrongh an opening 148 provided in the rear wall 149 of casting 101 for tlie'purpose,lsee Figures 3 and 10. A rabbeted seat 150'is machined about the opening 148 and inthe outerface of wall 149to receive a bearingplate 151 which is bolted to the wall of the housing at 152 and is formed with a boss 1531s which the reduced end 154 of shaft 146 is journaled. A collar 155 is clamped upon the shaft 146 and bea'rs'against bearing plate 1'51-to-prevent rearward movement of said shaft.

Thepower take-off housing 1567is bolted at 157 to the'rearwall of casting 101 about the opening-1 48' and the bearing plate .151 to encloseandsupport the parts to be now described. A counter shaft 158 is mounted in alignment with the shaft 146 in bearings 159'-1'60 seated in said housing and extends beyond the housing and is 'splined at 161;

The rear end of the housing is closed by a cover plate 162h'aving'a stuffing box 163 about shaft 158. Rings 164165 bearing against shoulders formed by an intermediate enlargement 166 of the shaft prevent longitudinal movement of the latter. A clutch jaw 167 of the helical-tooth type is keyed to the end of shaft 146'and a mating clutch jaw 168is I slidably mounted'on the splined end 169 .of

shaft 158. The rear end of clutch jaw 168 is reduced as at 170 and receives a spring 171.

which is compressed between flange 172 of said jaw and a cupped washer 173 on shaft 158. A shifting fork 173 is journaled on a shaft 175, the latter being journaled in lug 176 carried by cover plate 177 and extending into the housing. The fork 17 4engages the movable clutch jaw in the usual manner. A' handle 178 is mounted on the shaft 175 outside the housing and inside the housing the shaft is provided with an arm 179 having an adjustable stop 180 thereon which engages a pad 181 of the fork.

Normally the spring 171 maintains the movable clutch jaw in engagement with the jaw on the shaft 146. But by manipulating.

the handle in an obvious manner the movable jaw may be withdrawn from engagement.

- Moreover, the inclination of the jaw teeth is such that in the event that from any cause the shaft 158 moves in the normal direction of drive faster than the'shaft .146 or if it moves forward when shaft 146 is stationary,

' or if shaft 146 is driven backwards or in the reverse direction from the normal, the clutch sleeve 168 backs off thus preventing the shaft 158 from engagement with shaft 146 except when the latter is rotating to drive the for- "-mer in the proper direction of rotation.

the tractor may be sold without the attachments, cover Cplates being provided for the openings, an

at a laterdate the take-off may be procuredand applied. In applying thetake-off the unit comprising the gear wheel 126 is placed in position, the shaft 145 inserted through the opening 148 and inducted into the sleeve 126 at its forward end 7 and the bearing plate 151 and the housing 156 bolted in position.
