"FOR QUICK INFLATION"
This bottle filled with compressed air at 100 kilos allows you to largely inflate two tubulars to 4 kilos. Each bottle is tested at a pressure of 300 kilos before being put into service.
The right-angled connector, which does not change the rider's usual gesture, fits easily on all valves and has the advantage of not twisting the mechanism pins, provided of course that the connector is fully engaged on the valve. Simply screw the body on to open the bottle, and unscrew it to stop the compressed air outlet. The cylinder is provided with a centre point at each end for mounting on the bicycle frame itself.
always nice to see another Daniel Rebour drawing! I'm slowly making my way through Heiko's flickr pages.
I'm trying to figure out what a "kilo" translates into. I'm inclined to think it might be a kilopascal (kpa), but 4kpa is only 27.6 psi. I'm not sure how big the tubulars were back then, but 27.6psi seems quite low.
Of course, translation is always difficult, and especially when different eras and cultures are part of the translation. I like the comment "The right-angled connector, which does not change the rider's usual gesture", which I think means that the rider uses the same position/posture to use it as the rider would use when operating a Silca Impero pump. In the current culture in the USA, "the rider's usual gesture" suggests some sort of body language that is intended to send a message... probably not a happy message either, when fixing a flat.
