Abstract
RESTRAINING WHEEL MEANS
Abstract of the Disclosure A wheel restraining means having an upper rigid plate and a compressible air bag or similar flexible medium where a generally annular configuration is provided. This structure is mounted on a shaft and a conical member secures the struc-ture to the shaft. The lower compressible surface engages a wheel rim which is mounted on the shaft. The pressurable engagement between the undersurface of the wheel restraining means and the adjacent surfaces of the wheel rim serve to secure the wheel on the shaft.

Description
99sæ~
This invention relates to means for securing tires on shaEts so that they may be repaired or adjusted and particularly to structures known as adapters for se-curing tire wheels onto tire-changing rnachines or wheel-balancing machines.
Background of the Invention Wheel structures, at least in North American model wheels, normally comprise a central hub opening sur-rounded by a regular arrangement of spaced-apart bolt holes for securement to the axle. Such wheel structures ~ .
are still the most common. :
However, with the advent oE magnesium wheels and other more exotic or sophisticated forms of wheels, the .
structure of wheels has led to the provision of radial .
reinforcing ribs and the provision of a great variety o~ bolt hole configurations. ~;
Th.e accomodation and restraining of these latter .~ ~
types of wh~els on conventional tire changing machines ~ -has been awkward and time-consuming.
: ~ The conventional tire-changing machine has a central post which passes through the central hub hole of the wheel ancl a second, hinged, pointed shaEt which enyages a selected one of the bolt holes on the wheel web. ~.
A threaded collar mounted on the central post completes ~ .
the wheel securement.
With the "exotic" wheel forms the securement .:
:
cannot be e:Efec-ted as with the more common wheel.
At present these "exotic'l wheels are secured by means of a plate and pins~
The plate has a central opening which fits ,~ ;
5~31~
over the central post and a plurality of holes therein.
These holes are so arranged that -they will accommodate the difEerent configurations of bol~ holes ln -the wheels.
The vperat.or in using these plates inltially mounts the plate on the central post, consults a chart which i.nstructs him as to the appropriate selection of holes for the particular model wheel and aligns the clesignated holes with bolt holes in accordance with the chart indications.
A collar then secures the plate to the central post and ~ ~
a series of pins are passed through the plate to engage ~:
the bolt holes in the wheel and restrain the wheel from movement. The collar prevents movement of the wheel rim ~ ~:
along or up the post and the pins which extend through the plate to engage the bolt holes restrain the wheel from rotational movement around the post.
Summary of the Invention ::
It is the principal object of the present inven- :~tion to provide a means whereby any wheel having a central ~ .
hub hole may be accommodated and secured on the shaft of a tire-changing machine or the like with facility, speed and economy. :
To accomplish this objective, there is provided in accordance with the present invention wheel-restraining means for use in restraining a tire wheel rim a~ least ~:
relative to one direction on a machine, which machine has a wheel-engaging shaft; said means comprising a rigid - plate having an opening therein engageable with said post, a flexible member extending below the underside of said plate; said flexible member havi.ng a lower surface engage able wlth an adjacent surface of a tire wheel, and

These and other features and objects of the pre-sent invention will be more apparent from the following description and drawings in which several embodiments are illustratsd by way of example, and in which:
Figure l is a perspective top view of a tire-changing machine with a wheel of the "exotic" type sec-ured in position by maans of the apparatus of the prior art;

' -3a-When the tire is to be repaired, the tire in com-bination with the wheel rim is mounted;,on the tire changing machine 11 so that shaft 12 passes therethrough. The operator, since the example shown is a non-conventional wheel structure, then selects a plate such as 18 which is provided with the various holes such as 14, 15, 16 and 17. ~ ;
This plate is rotated until the respective holes are aligned with the bolt holes on the wheel web and pins such ~ ~;
as 19 and 20 are passed through the aligned holes 16 and 17 in the examples shown and secured in position. A collar 20 is then passed over the shaft 12 and made fast through its threaded engagement with the collar.
As will be seen, the various arrengements of the holes and the number of operations required to effect securement makes this operation both awkward and time- ; ~-consuming. In F1gure 2 the upper part of a tire-changing machine is generally indicated at 21 and has a table .?2 upon which an arcuate inwardly outwardly sloping surface 23 is provided. Through the upper surface of 23 a central shaft 12 and a pin ~24 extend in the manner shown. Pin 24 ;~
is so mounted that it may move in a planei towards and ~;
away from the central shaft 12. This permits engagement with bolt holes on the wheel web at various distances from the center of the wheel hub.
In this embodiment with the conventional wheel, the wheel 10 is dropped over or placed over the central shaft 12 and so arranged that the pin 24 engages one of the bolt holes 25. Over this assembly A wheel fastening mechanism 26 in accordance with the present invention is mounted and a collar 27 is passed over and threadably engaged with shaft 12. As collar 27 is threaded down the outside wall it engages with the inner periphery of the wheel fastening mechanism 26 to be tightly secured in position.
The fastening means 26 comprises an upper rigid plate 30 below which is provided an inflatable bag 31.
The inflatable bag 31 ls connected through an infla-ting ~ ;
valve 32 and a pressure relief valve 33 which extend through plate 30. ;
After the mounting sequence previously described has been followed the inflatable bag 31 is inflated from ~;
any given air source. The pressure relief valve 33 is so set that the pressure exerted by the inflatable bag 31 does not exceed 15 pounds pressure per square inch.
With this arrangement~ the wheel is now set and `~
firmly fixed in position so that operations may be carried out on the tire.
Figure 3 is illustrated as a perspective view from the top of a further embodiment with the wheel fastening means secured in position. In this embodiment ::: :
the wheel is one of the magnesium wheel structures.
With magnesium wheel structures the central hub hole is relatively weak. In the prior embodiment the cone 27 served to center the wheel and the wheel fastening means 26. In this embodiment because of the relatively fragile nature of the magnesium wheel hub struc-ture it is necessary that the wheel be centered and fas-tened by its separate mechanisms.
In the embodiment shown in E'igure 4 prior to mounting the wheel 10 on the central shaft 1~ a spring loaded cone ~0 is mounted so that spriny ~1 engayes the base or surface 23 of the tire-changinq machine. The en~
gagement between the upper surEace oE the cone ~2 and an adjacent edge of the magnesium wheel hub 43 centers the wheel on the shaft 12. The wheel Eas-tening means 26 is then mounted in the manner previously described and secured in position by means of cone 27 and again bag 31 is inflated to a pressure of 15 pounds.
The cone 40 will accommodate up to 25 dif~erent sizes of central hub openings, the present range of hubs.
It will, of course, be understood that this number may be varied by alteriny the slope 42.
From the foregoing, it will be seen that a new and simple means of fastening the wheels on shafts for the purposes of repair and adjustment has been provided and the operator can use these means with much greater facility and speed than previously.
It will, of course, be understood that various sizes of rings may be substituted for the lower conical member and it will also be understood that his wheel fas~
tening mechanism can be used with any form of machine for working on a tire Eor the purposes of repairing, adjusting or the like.
