Abstract

5523. British Thomson-Houston Co., [Allgemeine-Elektricitõts Ges.]. March 5. Fusible cut-outs.-The fuse wire 1 in a fuseplug is partly embedded in an insulating-mass of cement while one or both ends of the fuse wire are pressed between elastic material, such as disks of asbestos 5, 6. The elastic material is compressed by means of an insulating-cap 10 which screws on to a reduced portion of the upper contact 3 of the fuse plug. The cement may serve to hold together the two contacts of the plug, with or without a porcelain, steatite, or like sleeve 9, and the upper contact 3 may be provided with a hole through which the cement is introduced. The cap 10 is provided with an opening 11, or made partly or wholly transparent, in order that the fuse wire may be inspected, a portion of the elastic material being removed for this purpose. A number of fuse wires may be mounted in parallel in the plug, additional asbestos disks being provided so that only one wire is pressed between each pair of disks.
