Abstract: 925,611. Pressure gauges. W. GFOELL. Aug. 14, 1959 [Aug. 16, 1958], No. 27801/59. Addition to 797,905. Class 106 (2). [Also in Group XXIX] The combined tyre valve cap and pressure gauge disclosed in the parent Specification, is modified in that the stem of the safety valve is not coaxial with the axis of the cup-shaped piston indicator member. In the first example, Fig. 2, the stem 2 of the safety valve 1 is at right-angles to the axis of the piston member 35 which co-operates with a scale on a member 41 which surrounds the sleeve 40 extending from the top 39 of the cylindrical cap 27. The righthand end of the stem 2 is located in a,recess 19 in a movable elastic insert 18 of a cap 17. When the insert 18 is depressed against the pressure of a spring 10 the valve 1 is opened and the tyre valve stem 22 is moved to open the tyre valve so admitting air to the passage 23 to move the piston member 35 accordingly. The cap 17 has a vent passage 26. The cap nut 13 by which the device is attached to the connection piece 50 is attached to a brass sleeve 5 which surrounds the stem 2 within the body 4. The cap 17 is removed when the tyre is to be inflated and the piston member 35 affords a continuous indication of the tyre pressure. In other two examples the upper part of the casing has an elbow bend so that the piston member moves parallel to the stem 2.
