Description
This invention relates to tyre and wheel assemblies. In particular, this inven~ion relates to tyre and wheel assemblies in which a lubricating device is to be located in the inflation cham-ber ~o as to lubricate the tyre when running in a dePlated condition.
~ ifficulty has been experienced in attempting to locate a lubricating assembly in the inflation chamber of a tyre and wheel rim assembly. The present invention overcomes these difficulties and ;~ :
provides a simple and efficient assembly for inclusion in the in-flated chamber.
According to the invention, an assembly for inclusion into the inflation chamber of a tyre and wheel rim assembly com- ;
prises at least one container having a lip formed thereon, and means for locating and retaining the container in position on a wheel rim, said means comprising two loops formed from at least ~ ;
one length of material which loops being locatable circumferent~
ially around and substantially in contact with a wheel rim, the container being located between the loops, fastening means being provided to link the loops at each side of the container to maint~
ain said loops substantially in contact with the container whereby .
~ the lip on th~ container can serve to retain the container in position. ;~
According to the invention also, a tyre and wheel rim as ;.
sembly comprises a wheel rim having two bead seats and two bead retaining flanges, a tyre mounted on the rim defining an inflation chamber, and included in said chamber an assembly comprising st least one container having a lip fo~med thereon, and means for . :
locating and retaining the container in position on the wheel rim, ~; :
said means comprising two loops formed from at least one length of ;; ;
material, which loops are located circumferentially around and substantially in contact with the wheel rim, the container being located between the loops, fa~tening means being provided to link ~-.- .
the loops at each side of the container to maintain said loops ~ub~tantially in contact with the container whereby the loopon the container serves to retain the container in position on the wheel rim.
Although the loops may be made ~eparately, it i8 ,.,,,, ~.L~

preferred that a single length of material is used, the ende thereof being fastened toge~her. Alternatively, the loops may be formed by continuously fastening two continuous lengths of material toge~her at appropriately spaced-apart positions and then cutting therefrom paired lengths of the material sufficient to form the loops. The ends of the cut lengths may be joined together to form the loops ox alternatively the ends of the cut lengths may be arranged such that bo~h ends have a single container located therebetween.
The material from which the loops are formed has to be of a sufficiently high modulus to withstand the centrifugal ~orces to which it will be subjected during use in the tyre and wheel assembly when the containers are full of fluid.
Additionally the material preferably has a good elasticity when it is intended to assemble the assembly prior to inclusion in the inflation chamber to allow the loops to accommodate the normal engineering tolerances in the circumference of the wheel rims~ Therefore the material from which the loops are formed is preferably high extensibllity, i.e. 4 to 6% flexible steel wire cord.
Alternatively, if it is desired to assemble the assembly directly onto the wheel rim the cord ca~ be of lower extensibility. The wire may be ~rass plated or galvanised.
Pre~erably the container i9 made from aluminium and of -~
substantially cylindrical shape, one end ~eing provided with an aperture into which a sealing/release member for a fluid i9 located. The lip on the container is preferably located around the end thereof which is locatable adjacent -3~ ~-, . , , ~ .

with which they are to be usedO E~asteners 17 are attached to the two loops, one on each side of each container 13 whereby the cord locate~ on the lip 15 of the containers 13 and locates and retains the containers 13 in position.
The steel wire cords can be clipped or astened together to form the loop portions by any convenient means.
A method which has proved to be very satisfactory from both production and product considerations is to bridge the wires with a metal staple 17 and form the legs of the ~taple one round each wire (as shown in Figure 4). Mechanically this operation is quick and simple, involving only a staple feed device, a suitably shaped anvil and a small automatic press or hammer to force the staple onto the anvil and xound the wires. This produces an extremely effective connecting or bridging piece which is very strong since it encircles each wire and is swaged thereon. In practice it has been found necessary to feed the staples alternately from the top and ;;
the bottom of the pairs of wires since the action of swaging the staples round the wires twists the wires and it is necessary to reverse this twist if an unstrained and undistorted product is to be produced. A suitable material or the staple when using galvanised steel wire is galvanised mild steel sheet.
