DRIVINGFAXLE FOR LOCOIVIOTIVES.

Sl?EQIFJFQAVLIO1\l'` forming part of Letters Patent No. 700,038,` dated May.13,-19 02. Application filed November 27, l901.k .Serial No. 83,925. (No model.)

T all whom t may concern:

Be itknown that I, CHRISTIAN IAIAGANs,v

sia, Emperor of Germany, residing at Erfurt,y

in the Kingdom of Prussia, German Empire,

' have invented certain new and useful Improvem ents in Drivin g-'Axles forLocomotives, of which the following is a specification.

My invention relates to improvements in driving-axlesfor locomotives and is repre-1 sented in the accompanying drawings,Figures l to 8, viz:

Fig. l is a viewand longitudinal section of the driving-axle. Fig. 2 is a front View of the crank. middle of Fig. l of the hollow axle'. Fig. 4 is a longitudinal section through the hollow axle and its cross-joint. Fig. 5 isa cross-section of the cross-joint. tion of the lower part of alocomotive equipped withmyimprovements. Fig. 7isalongitudinal central section of'the same', and Fig. Sis a plan view thereof.

It is preferable toconstruct the driving-V' axle T' or'drivinglaxles 'of the locomotive,

which arelocated at a distance from the fixed axles, so as to'be adjustable in a radial and movable in a lateral direction. To thisend the driving-axle -T, Fig.`1, is embraced or surrounded'bya hollow axle H, which carries the Wheels and is `journaled in a revolving frame D, having its fulcrum about the pivot Z. It isthus possible for the locomotive to travel around sharp curves. The halves of the driving-wheel axles T are connected to the hollow axle or sleeve H by means of a cross-joint, the hollow axle forming the ring of the cross-joint coupling. This form of construction is shown in Figs. 4: and 5.

The sleeve His made in one piece. The four pins or pivots of the cross-joint are located side by side, and two pins are arranged at the end of` each =half driving-axle T. VThe halfaxles Tffare--ball-shaped at their ends el and -Iit in the hollow spherical bearings e c. Each Fig. 3 is a section through fthe' Fig. Gis a side eleva-A out at h, and a body e', worked. out on bothy sides in accordance therewith, is insertedpbetween the two. On reference to Fig. it will be seen that the bodyjl is seated equally in the correspondingly-formed1recess hin the 'ball ends d and thatV the bottoms of said re- In order to transferin oesses are concaved, while the opposite ends of the body e' are conyexed to secure the Ie` sult hereinbefore set forth. The ends of the joint-pins fare covered by caps 7o, closelytted upon the sleeve l-I to contain and retain v lubricatingmaterial-for 'the ball-faces d 71,. Each driving-axle half T can'easily be removed from the sleeve -H afterthe wedges gghave been withdrawn and they cups e' removed. Thelubricating material is very well protected, and the bearing-faces are secured against dust.

Having now particularly described and ascertained the nature ofthis invention and in Ywhat manner the sameis to be performed, I

declare that what I claim is- 15A device of the class specified, comprising asleeve provided with wheels, an axle consisting of a plurality of sections fitted in the sleeve, and the inner ends of the axle-sections being ball-shaped and the sleeve being slotted, spherical bearings in the sleeve for said ball ends, and wedges adapted to project through said slots and to bear against said spherical bearings for the purpose of adjusting the same.

2. A device of the class described, comprising a sleeve provided with wheels, anaxle consisting of a pluralityof sections lttedinlthe sleeve and having ball-shaped innerends, spherical bearings in the sleeve for said ball ends, and the lattervhaving recesses in their adjacent surfaces, and the bottoms of therecesses being convex, and a body fitted into said recesses and its opposite ends being ooncave.

3. A device of the class specified, comprising a sleeve provided with wheels, an axle consisting of a plurality of sections inclosed by IOO said sleeves and having ball-shaped' innell my hand in presence of two subscribing Witends, spherical bearings in the sleeve for renesses. ceiving said bali-shaped ends, pins extending,r 1 T 1 through slots in the sleeve lnd balbshaped CHRIS'I IAB HAGANS' 5 ends respectively, and caps upon the sieeve Witnesses:

covering the outer ends of said pins. PAUL FRISHMANN,

In testimony whereof I have hereunto set XVILHELM BINDEWALD.
