NEW Apparatus AND Appliances. · · A NEW CUTTER ARC LAMP HANGER.
A new form of arc lamp hanger which has been built by the George Cutter Company, of Chicago, is illustrated by Figs. 13 and 14. The lamp is supported by a split ring, A. The lamp is engaged by swinging the pivoted half of the ring upwardly and passing the fixed portion through the eye in the lamp, then closing the pivoted ring-section downward and into position, as shown in Fig. 13. The hook, A, is supported by a bolt, B, to which the hook is threaded. The bolt, B, is in turn supported by an insulator, C, the bolt being provided with a head, 1, and the insulator with a flat supporting portion, 2, upon which the head can rest. The hole in the insulator, C, through which the bolt, B, passes, is made a little larger than the bolt, to prevent cracking and binding. The supporting surface, 2, of the insulator forms the floor of a recess or socket, which is made to correspond with the shape of the head of the bolt so as to prevent the latter from turning and thereby allow the lamp-holding hook or ring. A, to be readily screwed on or off from the bolt.
The insulator, C, is supported by a couple of pins, D D, extended transversely through it, and separated from one another by a distance less than the length of the bolt head, so that the head of the bolt will catch and rest upon the pins, D D, should the insulator, C, become broken. The pins, D D, fasten the insulator, C, to the metal hood, E, which covers and partially encloses the insulator. The socket above the bolt-head is filled with insulating material, as is also the space between the hood and insulator. · · |
