Abstract
751,161. Locating punctures. CHIDIAC, G. C. May 12, 1954, No. 13897/54. Class 144 (1). [Also in Groups XI, XIX and XXVIII] A device for locating punctures comprises a mouthpiece 26 adapted to be applied to the source of a suspected leak to make a fluid-tight seal around the latter, a chamber 31 connected to the mouthpiece, and a piston 33 or flexible diaphragm in the chamber movable under the influence of any pressure rise due to a leakage, such movement providing an indication of leakage. The movable member 33, on displacement, may close an electric battery circuit to a lamp bulb 5. Alternatively the member 33 may have a rod 34 extending upwardly into a chamber 1, the chamber 1 being provided with windows and magnifying lenses whereby watch may be kept for any movement of the rod 34. The mouthpiece 26 is of resilient material and is detachable so that it may be replaced by a mouthpiece of different form, and the opposite end 14 of the device may be bored and slotted to serve as a tyre-valve core remover.
