VVHEEID` FOR VEHICLES.

Specification of Letters Patent;

Application filed August, 1912.v Sera1No,714,124.

To all whom t may concern:

Be it knownthat we, EDWIN JoNEs, a subject of the King of England, residing .-at The Poplars, Greenlield, near Holywell, North Wales, and WATKIN SALUsBURY WIL- LIAMs, a subject of the King of lllngland, residing at 17 Parlzfield road, Liverpool, in the county of Lancaster, England,fhave invented certain new and useful Improvements in or Relating to Wheels for Vehicles, of which the following is a specification.

This invention relates to wheels for vehicles, but more particularly motor Vehicles; and has for its object to provide a new or improved form or construction of pneumatic wheel suspension.

It has heretofore been proposed with the object of absorbing road shocks to provide between a wheel felly and an outer tirecarrying rim, hollow india rubber balls; each of said balls being adapted to lie in part within a hemispherical or approximately hemispherical cup or receptacle arranged on the wheel felly, and in part within a similar cup secured to the inner side of the tirecarrying rim. rlhe present invention relates to this kind of pneumatic suspension, and is characterized by the use of cups or receptacles secured to the felly and tire-carrying rim, which are of greater length in the direction of the circumference of the felly and rim than breadth; and the employment of inflatable bags or tubes, each of which when inflated, lies in part within and fills acup of the felly and the opposite cup of the outer rim. A bag or tube preferably comprises an air container properly constructed of india rubber, and fitted with a suitable air inlet valve, and an outer protective envelop or casing of canvas, or other suitable material. When the wheel is assembled, that is when the rim is in position around the felly, and each air linated bag or tube is partially inclosed by a pair of said cups, the edges of the latter are at such distances apart that they will not meet under the maximum displacements of the floating rim relative to the felly, due to vibration and road shocks. The ends, and in some cases the sides also, of said cups are preferably ared or outwardly turned in order to prevent any projecting or protruding portions of said bags or tubes from being nipped between same, and cut or chafed.

At the sides ofeach .pair ofsaid cups, plates are provided. for thepurpose of protecting:

the bagjor tube lying within same.y Said bags or :tubes may be'inflated separately,

or simultaneouslyas desired.

A'drawing illustrating this invention is annexed hereto, .in ywhich n Figure 1 is a view, partly in section of a portion of a wheel (the side plates referred to being removed); and Fig. 2 yis a transverse section drawn to an enlarged scale as compared with Fig. 1.

a represents lthe wheel spokes, and c the felly; to said felly c a plate ring or hoop d is secured.

e e indicate metal receptacles or cups of greater length in the direction of the circumference of the felly than breadth secured by rivets f to said ring d, and g g are similarreceptacles or cups secured to the outer ring or rim 7L by means of rivets 71,' y'

is a rubber tire or tread fitted to rim h.

Within each pair of cups e g a bag or tube is disposed, said bag or tube comprising a rubber air container Z fitted within an envelop or casing m of canvas or other suit` able material, which is slit in part to permit of the insertion therein of the bag or tube when uninflated, said slit being afterward closed by lacing or in other convenient manner.

n represents the inflating valves fitted to the sides of said air containers l; alternatively, however, the valve stems may be arranged to pass through the felly. Secured by two or more bolts o to each side of each cup e is a bag protecting plate p. According to a modified arrangement the ends of said cups of the felly and rim respectively may be arranged to butt together. v In the application of the wheel to motor vehicles the power or drive is transmitted from the felly to the `floating rim through said l n pneumatic bags or tubes.

Having now described our invention, what we claim as new and desire to secure by Letters Patent is:-

1. ln a vehicle wheel, a felly, a rim, confronting segment-shaped independent reent air-inflated bags arranged between the confronting receptacles, and side plates carried by each receptacle of said felly and engaging the flanged edges of the confronting receptacles.

2. A vehicle wheel comprising a felly, a rim, receptacles secured to said felly and having their longitudinal dimensions eX- tending circumferentially of the wheel, receptacles secured to the rini and of greater length than the receptacles of said felly, the receptacles of said rim and felly being substantially semi-circular and having the edges thereof flanged; air-inflated bags disposed between said receptacles, each of which lies Copies of this patent may be obtained for in part within and fill said receptacles, and plates carried by each felly receptacle and engaging the flanges of the opposite receptacle of said rim and coperating therewith in providing side inclosures for the bag between said receptacles that permit of said felly shifting relatively to said rim.

In testimony whereof we aHiX our signatures in the presence of two witnesses.
