Pass & Seymour Insulators


The accompanying illustrations, Figs. 1 and 2, show two novel forms of insulators recently introduced by Pass & Seymour, of Syracuse, N. Y. Fig. 1 is a circuit-break insulator, in which the distance between the wires is very great. This may also be used equally well as a tree insulator. It is made in two sizes, and is sufficiently strong to stand the breaking strain of any wire that may be fastened to it.

The cleat, shown in Fig. 2, is intended to take the place of those of wood, now in general use. It is so made that the wire may be held in position loosely until properly adjusted, when, by tightening the screws, it is bent in the rounded jaws of the cleat and held very firmly. This insulator holds any size wire from the smallest used to No. 6.


Both of these articles are made of Syracuse china, fully glazed. The cleat, however, is furnished in the unglazed state for concealed work.
