27,699. Harrison, J. Nov. 25. Tyres, pneumatic, inflating - valves for. The pneumatic tube a is gripped between the head c of a stem b having a screw thread on the outside, and a washer d held in position by a nut e. The stem is formed with a shoulder g forming a bearing for the spring n which forces upwards the valve spindle l, causing the valve i to bear against the valve face h in the stem, and so prevent escape of air. To inflate the tyre, a nut p is screwed upon the end of the stem and an inflator stem g screwed therein as shown so that a conical end q<1> thereof bears upon the top of the valve spindle and forces the valve open. When inflated, the inflator and nut p are removed and a covering-cap which enters the opening is screwed on to the end of the valve spindle, whereby the valve is drawn up positively against its seat.
