DRlVING-AXLE- MEOHAN ISM- SPECI IIFIGATION forming part of Letters Patent No. 753,022, dated February 23, 1904. Application filed December 1, 1902. serial No. 183,833. (No model.)

To ctZZ whom it may concern:

Be it known that I, RoLLm H. WHITE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Driving-Axle Mechanism, of

which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The invention relates to the driving-axle mechanism of an automobile, and particularly to the means for properly mounting and effectively driving the divided axle and t0 the means for connecting the wheels and brakecylinder to said axles.

The invention, which is specifically set forth in the claims, may be here summarized as consisting in the construction and combination of parts shown in the drawings and hereinafter described.

' In the drawings, Figure 1 is a plan view, partly in section, of a little more than half of the rear axle and associated mechanism. Fig. 2 is a sectional side elevation on line 2 2 of Fig. 1; and Fig. 3 is a plan view, partly broken away, of the parts at one end of the axle, showing the manner in which the wheelhub, brake-cylinder, and axle are connected so that they must rotate in unison.

The rear axle is composed of two alined sections A A, which meet or may meet in the longitudinal center of the vehicle. These axle-sections except their projecting outer ends are inclosed in what may be termed a housing. This housing consists of two alined tubes B B, in which the axle-sections are rotatably mounted, and an interposed gear-case C. The gear-case is composed of two halves c a, each having the sleeves c c, which embrace and are rigidly secured to the inner ends of the tubes B B by brazing or otherwise. Each half of the gear-case is provided with the forwardly-extended half 0 of a sleeve, which when the casing-halves are bolted together by bolts 0 going through the flanges c, embraces and holds a bearing-sleeve F. This sleeve has external flanges f f at its ends, between which the sleeve 0 0 lies,

whereby endwise movement of the sleeve relative to the gear-casing is prevented.

A longitudinal driving-shaft D is rotatively mounted in this sleeve F, or rather the rear section a? of the driving-shaft is so mounted, because it is preferable that the shaft shall be made of sections flexibly secured together, as by universal joints cl.

On the inner end of the shaft-section (Z is a bevel-gear (Z preferably formed integral with said shaft-section. In' the back face of this gear is an annular groove 01 which forms a raceway for the balls L, and between these balls and the end of the bearing-sleeve F a hardened-steel washer f is placed, against which the balls bear. A hardened-steel collar d is screwed upon the outer end of this shaft-section and bears against a steel washer f interposed between it and the outer end of the bearing-sleeve F. When this screwcollar is adjusted properly, endwise movement of the shaft-section in the sleeve F is prevented, and the adjustment is maintained by a jam-nut d, which also screws onto the shaft-section d.

Within the gear-casing is abuilt-up hollow member E, having hubs e e, which-are rotativelymounted upon the axle-sections A A within the gear-case. Rigidly secured to this member is a bevel-gear e which meshes with the bevel-gear 0?. Within this hollow member are two bevel-gears J J, which are respec-' tively pinned or otherwise rigidly secured to the ends of the axle-sections A A. Between these gears and in mesh with them is a bfiVCl'. gear K, (or several bevel-gears,) mounted on radial shafts 6 secured to and carried by this hollow member. The rotation of the shaft D through the described gears causes the rotation of both of the shaft-sections A A at the same or different speeds, as circumstances require.

A bearing-sleeve or bushing M is screwed into the inner end of each of the tubes B and serves as a bearing for the inner end of the axle-section, which passes through it. Be.- tween the bearing-sleeve M in each one of these tubes and the adjacent hub of the hollow member E two steel disks P P are placed, and in their proximate faces annular grooves 19 are formed, which serve as raceways for the balls P These two ball-bearings serve as thrustbearings for the member E and the axle-sections as well, preventing any movement which will disturb the proper relationship of the described gears. These two bearing-sleeves M are adjustable in the tubes B. Worm-teeth m are formed on each sleeve M, which teeth are engaged by a worm N, mounted in asuitable bearing-socket c, which may be formed either in the hub 0 of the associated gear-case or partly in it and partly in the tube B, which is securely fastened in said hub. In either event the worm extends through said tube B into engagement with the worm-teeth of the bearing-sleeve. The outer end of the wormshaft is squared for a key, whereby it may be turned. The end of the socket is closed by a screw-plug c or by some other means.

The outer end of each shaft-section has a ball-bearing in the tube B. It consists of a sleeve T, fitted upon said axle-section and abutting against an annular shoulder a thereon. In the periphery of this sleeve are one or more annular grooves t for the balls 25, and in the end of the tube B is driven a steel sleeve V, which serves as the outer part of the ballraceway. The annularly-grooved sleeve T is not directly fastened to the axle; but its outer end is provided with tongues 23 which fit into corresponding grooves w in the inner end of the wheel hub W. The inner end of the wheel-hub is of reduced external diameter, forming thereby the annular shoulder w. Upon this reduced portion of the wheel-hub the hub y of the brake-cylinder Y is fitted, and this last-named hub is provided with tongues y, which enter recesses or grooves w in the hub of the wheel. The brake-cylinder hub is held so that its tongues will engage with the grooves in the hub of the wheel by means of a nut X, which screws upon the wheel hub. This nut has a notched edge, and when the nut has been screwed up so that the parts are in the proper relative position it is locked in place by a screw 00, which screws into the brake-cylinder, so that the head of the screw enters one of the notches in the periphery of the nut. The outer end (1, of the axle is made square or of some other angular form, and this part of the axle fits a correspondingly-shaped hole in the outer part of the wheel-hub. When the parts have been assembled as described, they are held in place by a nut a, which screws upon the threaded end of the axle. The axle of necessity rotates the wheel, and because of the tongue-andgroove connections described the rotation of the wheel is necessarily accompanied by acorresponding rotation of the brake-cylinder and ball-bearing sleeve T. Felt washers Z Z are held so as to close the annular space between the cylinder V and sleeve T.

Having described my invention, I claim-- 1. The combination of a gear-casing composed of two connected parts, and two alined tubes respectively connected with said two parts, with two axle-sections rotatively mounted in said tubes and extended into the casing, wheels secured to the outer ends of said axlesections, a hollow member within the casing rotatively mounted upon the ends of said axlesections, two bevel-gears secured respectively to said axle-sections within said hollow member, a bevel-gear meshing with both of the bevel-gears last named and rotatively mounted on a radial shaft secured to and carried by said hollow member, a bevel-gear secured externally to said hollow member, a forwardlyextended bearing-sleeve secured to the gearcasing, a driving shaft section rotatively mounted in the last-named bearingsleeve, a bevelgear secured to said shaft within the gear-casing in mesh with the bevel-gear secured externally to the hollow member, thrustbearings at both ends of the hollow member, means for adjusting said thrust-bearings, and thrust-bearings for the driving-shaft at both ends of the sleeve in which it is mounted, and means for adjusting said thrust-bearings, substantially as specified.
