E., and EATON, J., (trading as UTILITY ELECTRICAL CO.), Wednesfield Road, Wolverhampton, GORRINGE, R. C., 32, Compton Road, Wimbledon, and GAMBRELL, H. W., 13c, Park Road, Chiswick, both in London. June 10, 1932, Nos. 16491 and 24732. [Class 39 (ii).] A portable electric lamp adapted to throw a beam of light is provided with a magnetic compass needle 11 pivoted coaxially with the beam, with the compass scale 9 disposed around the periphery of the beam, so that the compass is illuminated without obstructing the beam. The needle 11 is pivoted on a pin 12 supported by a bar 13 from the scale 9, the N and S arms of the needle preferably being of dissimilar form, for example the N arm may be pierced by a small hole. The compass is mounted within a cap 8 which screws on an intermediate sleeve 5 containing the reflector 6, with a glass disc 10 fitted above the compass needle. A cover 14 hinged to the cap 8 is provided with a mirror on its underside, and on its upper side is hinged the gnomon 18 of a sundial arranged to lie flat on the surface when not in use. When raised the gnomon is retained in position by a blade spring bearing on its hinge. The sleeve 5 is formed with a diagonal slot 7 which engages a pin 4 on the battery casing 1 to provide a focusing adjustment. A removable bottom end-cap 21 screwed on to the body 1 is fitted with clips 22 to carry a spare bulb 23. The hinge-pin 15 of the cover 14 is formed with an external loop 16 by which the torch may be suspended. |
