i This invention relates'to the type of vehicle wheel in which "the securing nuts are enclosed in a relatively deep and substantially cylindrical casing, the outer end of the cas-V ing having usually been closed bya capwhich must, of course, be detachable in order to provide-access to the securing nuts. In the case of'wire wheelsthe'casing has, usually formed the outer hub or shell towhich the spokes are attached, whereas in-the case of sheet metal wheels the casing h'as'been attached'to the outer surface of the nave of the wheel.

with an inwardly extendingflange of the cap.

The cap, which has been'formed of light sheet metal, has been heretofore provided witha peripheralfiange to rest on the outer 1 end ofthe casing as well as with the above nientionedinward flange to enter thesaid end,cnecessitating the formationof the cap by spinning instead of simply by pressing.

"For the above reasons the cap has been'comparatively expensive to; manufacture,-and,

owing to the double thickness of metal where the peripheral flange is placed, a crevice exists into whichpenetrates acid during the platin-gvprocess which results in corrosion.

According to the mainfeat-ure of the pres ent invention, the casing is permanently bridged over at its outer end with a wall. which is rigid therewith but has relatively; large holes through the end in positions over a ""i the .nuts to affordaccess thereto. I a The end closure is preferably pressed in one piece W th ide wall ofthe shell...

Owing to the fact that the nuts are sltuatedf somewhat closeto the wall of the casingthe 3'. holes in'theend conveniently have their cen-.

tres somewhat inwardsof the axes ofthe nuts, and they are relatively/large so that a 31: T o facilitate this th e holesfmay be widened casing gives It has heretofore been usual to. cut out the outer end of the casing except. for a narrowinwardly extending flange or gallery, and; in some cases this flange has been utilized for the engagement therewith ofspring clips carried :by thecap. Inother v cases spring clips have been mounted inside Ithe casing, and have been adapted to engage out somewhat atithose parts which lie to i l the peripheral wall of the casing. :Each hole may, if desired, sufiice for two :or. more nuts-q i The] leaving of the end intact .;with the it considerably increased strength, so that, if desired', a lightergauge metal maybe used; but, in the caselofawire" wheel, it maybe found expedient-to provide an interior metalfband through" which'the 1 60; i

inner ends of the outerset f spokes'are passed,- such-band. being a good fit within to by-spot' welding." ,The band may, howthe casing and being preferablytacked 'thereever, be unattached to the casingasthe spokes will draw it securely against, the inner wall. thereof, to facilitate -which, the band may be split ifnecessary. The provision ofthe band renders it. a simple matter to'form the countersinks for the holes,as this can: be done beforeithe band isputin place.

Themetal of theend. ofthe-rsingat the j middlethereof is utilized as a medium for securing thecap inplace, and thelatter'fmay be formed as a simple pressing which,-,when secured in place, isvpulled up against-the end wall of the casing. Ayery simple and inexpensiveform of pressing is all that is i required because there is no inward or pen ripheral flange needed a-c'entral securing means being sufiicient tokeep the capproperly' in place. As there isfno spinning operation' required,;the cap may bemade ofsteel instead of brass as has heretofore usual:- 7 i i ly been necessary.

The securing means for the cap con-,1 sifst of a central set s'crew,the head-10f which maylie within a recess pressed inthe centre of the cap while the shank passes through, i' Q ahole therein and screws iii to the centre of the-outer wall of theicasing or a fitting secured thereto; .When it is required to remove the wheel the screw can be readily removed,'- i

such'asby the useof a coin fitted into af'milled slotin afmanner well-known} Th6 screw may, however, be rigidly secured to'the cap inwhich case the cap turns with the sc'r'ew'.

A headed pin with alspringgrippingdevice at its inner end for engagement with the hole in the centre offthe end wa-llgjoif the j casing V inc v maybe utilized, or any other type of spring fastening aswillbe readily un'derstood. I

The cap maybe pressed-to any desired shape adapted to fit up against theouter surface of the end wall ofithe casing; but it 7 7 should preferably terminate at'itsp'eriphery an edgewhich is presentedto the-said endwall so that it obtains a good consistent hold thereo n the whole way round. The edge may be beaded, if desired, for additional strength, 'Owing to the fact that'there' is aconsiderable amount of spring between the middle ofthe' cap and thecentre of the end wall, the securing screw has no v-tendency'to come undone.
