.To all whom, t may concern:

Be rit known that L'Loors P. MooERs, a citizen of the United States, residing at Cleveland, in thev county of Cuyahoga and State of Ohio, have inventeda certain new and useful Improvement. in' Power-Trans- 'mitting Mechanism for Automobiles, of which the followingis a full, clear, andexact description, reference being had to the accom-- panying drawings. i-

The invention relates to thejm'echanism which forms the OperatiVe'cOnnectiOn between the driven wheels and the longitudinal machine. y

, The particular object 'of this invention is to` provide a construction,- includingthe diiferential gearing, wherein all ofY thel working parts will be incased, but in such mannerthat all of said parts may be disconnected 'from driving-shaft of an automobile or analogous the driving-.wheels and Aremved from =thev casing for the purpose of repair orreadjust-A ment or may be properly adjusted before they are pnt into saidcasing.

vThe invention maybe here summarized as consisting of the construction' and combination of parts hereinafter described, and pointed out deiinitely in the claims.

ln the drawings, Figure lis a plan view of saiddriving mechanism when the uppercap of the `casing is removed and most of the parts arev incentral horizontal section. Fig. 2 is a plan view of the .mechanism as it app ars when -the casing-cap only'is removed.

ig. 3 is a transverse sectional view on line l 3 350i Fig. 2. f Fig: 4 is a ltransverse sectional viewl on line i '4 of Fig. 2. Fig. 5 is a sectional view on the line 5 5 4of Fig.- 2, and Fig. 6 is a detail in section on the line 6 6 of Fig. 2.

Referring to the parts byA letters-A representsfa centrally-disposed casing, from which Vtwo tubes a' a, which are rigidly fastened to l. the-casing, extend ylaterally inopposite directionstoward the side ofthe vehicle. The

casing consists of a body portion, which is the lower -half of it andthe part' to Which-tl.L tubes a are rigidly connecte'd,fandfa removf able cap a', a portion of which is shownin Figs. Ltand 5, the plane of separation between the body and capi being substantially diametrical. `Spring-sects B- are secured `to the .tubes @,wherebv said tubesmay be connected with the springs which support the vehicle-body.

The driving-'axle is divided, andthe twofggA pai Ss thereof C areconnected and driven@ byl differentialv gearing of suitable construction. This die'ren'tifall gearing as anen# tirety ris' rotatably supported in 4bearings f uponthe casing A. Prior to my invention oo the diierential -gdaring was rotatably sup)- ported, upon the axle-sections, which'were. in turn mounted inbearingssecured te thefcas-` ing. The dilerential-:mechanism `shown in' cludes arotatable` dr'mnD, which `has two oppositely-extended hubs d, which hubsare rotatably mounted ori-:.ballbearings in ringsV E. Each; of-these rings, has twolearsr e, by means; of which said rings maybe'prigidly but removably and adjfustablysecured to the casing- Thisdrum-carries al plurality off: planetary. gears d, which are located .insidel j -ofj` the drum and in the: specific 'form ishown are independently rotatable upon axes whichv are parallel with the vaxis of the drum.'k The-75 differential mechanism includesv two gears N 5 which are inside of the ,drum- .andlare inde- 'pendently-mounted, so as to be 'rotatable-fabout an axis which is coincident with 'the-4 axis of said drumand the axle-section.. Thesel gears N are so mounted by beingattached to extend out through and are rotatable in. hubs;

planetary gears d, andv the'g'ars N which differential gearing, which, as stated,` is ro.-V tatable bodily upon the ball-bearings in ther: adjustable rings E. Rotary motion is -trans- -g mitted to this differential gearing fromthev driving-shaft 'J by means of a beveled gear as stated, rotatably mounted in the hubs of said drum. The operative connection bej tween eachof these axle-sections and the l shaft c is such as compels them to rotate in the inner ends of short shaftfsections c,which.1 'l

d of the drum.- 'This differential drum, vthe I' mesh with the planetary Vgears in a familiar. manner, .constitute-whatv may bev called the'.

the outer ends-'ofthe shafts c', which are,- roo unison, but permits the .axle-sections to be l drawn longitudinally outward, so as to sever lftween said short shaft and axle-sections is one form of universal joint, and, as shown, is

specifically of the wit: The outer end of each short shaft c is enlarged, and in this end is formed a diametrical groove c2 wide enough to 'loosely receive the squared collars c3. These collars are loosely fitted on studs c5, which project radially from a collar c, which is non-rotatably secured to the inner end of the corresponding axle-section. ln the specific construction shown this collar c6 is fitted onto the squared end of the axle-section and' is held thereon by a cotter-pin c7, The oper- 'ative connection between each axle-section and the differential gearing is attained by the inward endwise movement of the axle-section, which causes the squared collars c3 to engage, as stated, in the groove c2. This universal joint may be concealed and in some measure protected by a sleeve 08, which is secured to the outer end of the short shaft c.

The described engagement between the axle-.section and the differential gearing is maintained so long as the outward endwise `movement of said axle-section is prevented, and it is prevented in the construction shown because it is connected with the hubvG of a I jects out of the tube a.

' bearings in which the hub of the differentialv6g follows? A con d '1S is rotatablymounted the outer end thereof the bearings for said hub being adjustable ball-bearings of familiar form which when adjusted prevent the endwise movement of said hub relative tol the tube. The outer -end of each axle-section is squared and pro- A. flanged collar Fis fitted to the squared outer end of said axlesection, and it is provided with clutch-jawsf, which engage with correspondin jaws g on the outer end of the hub G, and t is engagement is maintained and relative endwise movement of the axle-section and hub is prevented by means of a cap H, which is fastened to the hub and has a fiange h, which overhangs the flange g of the collar F. The rear section J lof the longitudinal drivingshaft projects into the casing, as before stated, and is rotatably mountedI on ballbearings in two rings K K', which a're rigidly but removably and adjustably Secured to the casing.

The s pcciiic construction shown of the b all- 1driving-wheel which upon the tube near drum is rotated is las following construction7 to,f

' sponding The employment properly positioned, they will 'tial mechanism,

fitted upon the hub, abutting a yshoulder thereof.

e. A second cone d2 is slidably fitted upon -said hub, and the-balls occupy a raceway formed betweensaid two cones and the groove 'tudinal groove lin the hub d', whereby t e rotating. The washer has a plurality of holes d6, arranged concentrically, and a pin dkjuay belpassed washer is prevented .from

thrpugh any one of these holes into a correhole in the Vadjustment-nut d3,

The ring E has an internal groove l .v in said ring. The cone d2 maybe adjusted tor` whereby the rotation of said nut is prevented. The washer is maintained in a position against the adjustment-nutby a-lock-nut d8. of the bearing-,rings E E K Kl are exceedingly good specific'means for l attaining very desirable'results in mechanism of thissort. The differential drum is through the rings E E mounted directly upon the casing and is wholly supported thereby independently of the axle-sections.'

The differential drum may be moved -axially to take up slight wear in its ball-bearings or to cause the gear D3 with the gear M, and the driving-shaftJ may also be moved lendw'ise to better insure the' proper intermeshing of said beveled gears or for any other purpose. The construction which permits these last-named adjustmentsis shown clearly inFigs. 2 and 4. The rings E E and K K are connected to the casing by screws R, which pass loosely through lthe holes in the ears and screwl into the casing. The rings may then be adjusted nicely by means of set-screws R,which screw horizontallythrough said ears and into contact with to mesh more accurately loo the screws R. i When said rings have been positions by tightening up the screws R. This adjustment of the differential drum has no effect upon the position of the axle-sections.

N; but they may'with equal accuracybe regarded as inner sections of the axle.

As a matter of fact, they are the means for mounting `the gears N and serve for repair or adjusffl to connect fthem.
