Abstract
228,270. Automatic Telephone Manufacturing Co., Ltd., and Nixon, J. Nov. 1, 1923. Selectors.-Eleventh or auxiliary terminals, to which a statistical meter may be wired, are added to each level of a standard test-terminal bank by means of specially-shaped metallic members each provided with a projecting portion which is bent so as to lie in the path of the test wiper. In the construction shown, the speciallyshaped members consist of arcuate strips 15 inserted centrally in the insulation between the test terminals 10 of two adjacent levels, the projecting end portions 17 being suitably bent so as to lie in the same planes as the terminals 10. Specification 24343/14 is referred to. The Provisional Specification also refers to a modification in which the strips carrying the auxiliary terminals may be mounted on a supporting post.
