Abstract

445,761. Tension indicators. DORNIERMETALLBAUTEN GES., Friedrichshafen, Germany. Nov. 18, 1935, No. 31902. Convention date, Nov. 17, 1934. [Class 106 (ii)] The tension in air-tight fabrics such as the envelopes of gas-filled aircraft is measured by placing a vacuum chamber 2 on the fabric and exhausting the air inside the chamber so that the fabric bulges into the chamber and measuring the deflection thus formed. The mouth of the chamber 2 is provided with a sealing ring 3 of rubber and is provided with an air-pump 9 and a vacuum gauge 5. The bulging of the fabric moves a rod 6 against the influence of a spring 7, the movement being transmitted by rack-and-pinion 10 to a pointer 11 moving over a scale 8.
