Granted: 1902-04-10
Abstract: 8110. Harrison, H. T. April 19. Couplings.-An arc lamp is raised to an overhanging arm by a winch and wire, and is supported and connected electrically, when in place, by a coupling on the arm. The stationary part of the coupling, Fig. 1, rests on a spherical support 2 at the end of the overhanging arm, to swing with the lamp. The wire from the winch is passed round pulleys 5 in the arm and the support 2, and under a sheave 4 on the top of the lamp, its end being secured in the support 2. This arrangement prevents the lamp from turning while being raised. An insulating-disc 11 on the top of the lamp is within the stationary part of the coupling when the lamp is raised, and carries two long upright springs 6, the upper ends of which are provided with inturned hooks 6<a>. These pass on opposite sides of a cross-bar 7 on an insulating- plate 10 in the coupling, and rest on it to support the lamp. Each hook carries a pivoted loop 8. If the lamp is raised above its normal position, these loops pass the cross-bar 7 and cover the hooks, so that these can be lowered past the cross-bar ; in a modification, the loops bear against the cross-bar and press the hooks outward as they are lowered. The insulating-disc 11 on the lamp carries electric connecting-springs (not shown) which receive strips fixed on the insulating-disc 11. In modified coupling, Fig. 6, the lifting-wire is attached to a vertical rod 22 on a plate 11<a>, which is connected to the lamp by a ball-and-socket joint 27. A casing fixed on the end of the overhanging arm carries a central tube 23, into which the vertical rod 22 fits when the lamp is raised ; in this position spring hooks 6<a> carried by the plate 11<a> engage and rest on a circular collar 7* on the central tube. The lamp and plate 11<a> are thus free to turn. In the raised position, four groups of upright springs 12 on the plate 11<a> make contact with two metal cylinders 9, 9<a> carried in the casing.
