Abstract
Abstract A hose with a standard automobile tire valve in each end is used to transfer air from an inflated tire to a flat tire. The standard valve in each end of the hose prevents loss of the air and also depresses the stem of each tire valve. The rubber tube is soft at each end to flow under air pressure, but is confined by a layer of fabric.

Claim 1
Independent Claim
207 words
In an inflating device having a. a long conduit with b. a valve mechanism on each end for connecting onto the valve of a tire to transfer air from one tire to another, c. the improvement comprising: d. each of said valve mechanisms including a standard automobile tire valve having, i. a rigid tube, ii. a valve seat threaded coaxially within the tube, iii. a valve stem mounted coaxially within the valve seat, iv. said stem extending beyond the seat on one side with an operator extension, v. said operator extension extending beyond the rigid tube to open a valve of a tire, and vi. said stem extending beyond the seat on the other side with a valve disc, e. said rigid tube being telescoped within a rubber tube which forms the long conduit and has i. a yieldable interior surrounded by a ii. limiting non-expandible fabric layer so that when the rubber tube is telescoped over a valve of a tire, then the rubber tube in the area between the valve of the tire and rigid tube is exposed to air pressure, thus the rubber flows from said area to squeeze the rubber around the valve of the tire because of the confinement of the fabric.
