Abstract

683,045. Revolution-direction indicators; speedometers. E.M.B. ELEKTROMOTORENBAU AKT.-GES. Nov. 14, 1950 [Nov. 23, 1949], No. 27754/50. Class 106 (iii). [Also in Groups XXVI and XXXV] A device for ascertaining the speed, the direction of rotation and for turning the shaft 1 of an electrically-driven circulating pump 2, the rotor of the electric motor being on the shaft 1 and immersed in the circulating fluid, comprises a guide member 13 in the pump walls 9 for a slidable rod 15 having an actuating member 18 at its inner end, the actuating member 18 co-operating with a driving member 25 on the shaft 1 when pushed into engagement therewith. The rod 15 may be shaped like a screw-driver at 18 and the shaft 1 may have a diametrical slot at 25, but any other inter-engaging shapes may be used. The rod 15 has a conical shoulder at its inner end cooperating with a seat 21 on the guide 13 to prevent leakages when the rod 15 is not is use. The outer end of the rod 15 has a head 17 with an axial recess for the application of a tachometer. The head 17 may be shaped such that it may be turned by a screw-driver or a spanner to turn the pump should it become blocked. Leakages are also prevented by an outer cap 24 screwed on to the guide 13 when the rod 15 is not in use. The stator 8 of the electric motor is separated from the rotor 3 by a water-tight cap 11.
