Abstract

118,882. Parnacott, A. E. Sept. 12, 1917. Viscosimeters. - Apparatus for detecting leakages of air or for measuring the viscosity of liquids comprises a capillary space between a surface and a transparent plate, a thin film of liquid in the space, and means for admitting air or gas to the space. In the form shown in Fig. 1, for detecting leakage through sparking-plugs, the transparent plate c rests on a surface b of a member a connected to a tube j having a collar for a washer to make a sealed joint with the plug or plug-carrying member. In a viscosity meter, a film f<1>, Fig. 4, of the liquid to be tested is disposed between a transparent plate c' and the bottom of a jacketed cup a', variable air pressures being exerted on the film by varying the immersion of a calibrated tube j<1> in a vessel k. In a modification, the pressures are produced by a hand-pump, and the viscosity is indicated by a pressure gauge.
