Abstract

178,859. Landis & Gyr Akt.-Ges. April 21, 1921, [Convention date]. Casings for meters comprise an integral die casting of brass or aluminium allov forming a base plate 1 with a surrounding rim 2, constituting the base portion of the housing, and supports 3, 4 to which all the meter parts are attached. Suspension lugs 5 may be provided, and other lugs for attaching the cover. An annular groove 10 may be formed in the rim 2, to receive a packing cord for making a dust-tight joint with the cover. Specification 15811/13 is referred to.
