inner tube

On our last day together in Greece, we took the adventure wheelchair and swapped out the back bike tires for enormous inflated inner tubes almost the size of small car tires.

Après-ski dance parties in crowded bars may not be a great idea this winter, but you can still boogie under disco lights—on an inner tube.

The inner tube has an internal flanch, to which a flat circular plate is screwed to close up the tube.

The inner tube is of the same diameter as the flue, and forms a continuation of it.

The tubes constituting the condenser and inner tube of the air-vessel may in all cases be 1/8th of an inch thick.

If the tyres are allowed to go flat, the weight of the machine will be likely to "nip" the inner tube.

Care must be taken when joining on the side piece that the inner tube is not heated enough to fuse it.
