146,840. Schermuly, P. May 20, 1916. [Convention date]. Prospecting a n d w a t e r - finding. - Minerals, coal, water, oil, &c. are located by divining-rod apparatus comprising a rod a of steel, iron, copper, or other metal, or of a combination of metals, or of wood, rattan, whalebone, &c. which is suitably coiled to form elastically - connected branches, one branch being supported in bearings b and the other branch, which passes through a slotted graduated guide c, being graduated and free to oscillate and adjustably carrying a spring or slide d to which is suspended a reacting substance or a container e therefor. In a modification, two rods a, Fig. 3, are pivoted on a stud g by means of a spring ring h. The apparatus may be inverted and is stated to be applicable for analysing and testing purposes. The reacting substance is preferably of the same nature as the substance sought for, but sulphur may be employed in gold-finding and a mixture of specified metals in water-finding. Specification 979/12 is referred to.
