SHEET-METAL WHEEL.

Specification of Letters Patent.

Application led. February 25, 1920. Serial No. 361,190.

To all fwwnt 'it may concern:

Be -it known that I, PIERRE L. Lmssn,

' citizen of the French Republic, residing at This wheel is formed in a known manner by a stamped sheet metal annulus ci conical form. The annulus is provided with a central opening to facilitate mounting and demounting of the wheel. The wheel 1s secured by bolts and nuts on a disc of a diameter corresponding to the central opening in wheels, the disc carried by the ub is thenv panying drawing,

the annulus and carried by the hub or the axletree arm or stub shaft.

When these wheels are emplo ed as rear replaced by the brake drum. Wheels of this t pe having a large central opening, are lighter than the stamped sheet metal wheels generally employed,`which facilitates mount.- ing and demounting of these wheels; further, the vibratory movement of these wheels is less than ordinary sheet metal wheels, because they are actually formed of twoA members, the disc and the annulus connected by means of bolts.

The invention further relates to arrangements of details which prevents the loosening of the securing nuts of the annulus to the disc as hereinaterexplained.

In order that'the invention may be clearly understood reference is made to the accomwherein Figure 1 is ya vertical section of a metallic wheel in accordance w th the present invention, mounted on the rear axle of a vehicle;

Figure 2 is a side view of part of the wheel in side elevation.

Fi re 3 shows a developed section of the ann us and disc adj aeent the securing bolts.

`The wheel is formed in the ordinary manner by a stamped sheet metal disc 1 so as to form a light conical structure. To the pe- Patented Jan. 17, 1922. y

riphery of the disc 1 is riveted or'otherwise i suitably secured a felloe to receive the ,pneug matic or other tire. The annulus lis proin the construction where the wheel is mounted `on the rear axle of an automobile, on a brake drum 4 carried by the end of the transmission shaft 5. The annulus lis secured on the brake drum 4 by bolts and lnuts 6, 7 the bolts are non-rotatably mounted in the drum 4. The inner periphery ofy lthe annulus l is slightly corrugated, the co1'- rugations being preferably radial (see Figure 3). nulus is made thus acquires a certain amount; of elasticity, which on account of this elasticity prevents accidental loosening of the nuts 7 In the case of front wheels for an automobile, the brake drum 4 may be replaced by a disc of suitable diameter, secured to the axlef Y tree arm or stub shaft and on which isboltedthe metal annulus of the wheel.

A metallic Wheel of this kind, havin a large central opening is of great/rigity v vided with a central opening 3 and is securedy..

The sheet metal of which the anand is lighter than metallic disc wheels geni erallyemployed. The vibratory movement of a wheel formed of two interconnected pieces or members is inferior to that of a disc wheel formed in one piece. Further in the case of rear wheels the utilization of the brake drum permits. of employing a more simple construction of hub, as well as an appreciable economy in construction.

Claim- A stamped'sheet metal wheel of the disc type, comprising an auxiliary, axle-supported disc-like member, a central opening formed in the'web of said wheel, radial corrugations provided adjacent said opening, adapted to engage the auxiliary disc-like member, and fastenings for resilientl securing together, at the junction thereoi, the web o f said vwheel and its axle-supported disc-like member.

In testimon whereof I a'lix my signature, in presence o two witnesses..
