Abstract
414,508. Automatic exchange switches. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and HUMPHRIES, H. E., 61, Rochester Way, Blackheath, both in London. July 5, 1933, No. 19065. [Class 40 (iv).] The switch mechanism when withdrawn from the terminal bank for the purpose of test or adjustmentis supported in close proximity thereto by a mounting which is readily attachable to the bank assembly or to the framework carrying the bank assembly. As shown, the mounting comprises three plates 12, 13, 14 clamped together, the outer plates being of insulating material and the inner plate of metal, and carrying a supporting bracket 15 similar to the bracket 4 attached to the bank assembly. The plates are cut away at the corners so as to form slots which co-operate with brackets 6-9 secured to the irons 10, 11 of the panel or rack on which the switch is mounted. To attach the mounting after the switch mechanism has been withdrawn, it is raised to engage the upper slots with the brackets 6, 7 and then allowed to drop so that the lower slots engage with the brackets 8, 9. The outer plates 12, 14 may have bevelled edges at the top and bottom, and the plate 12 is preferably light in colour to facilitate inspection of the mechanism. The Complete Specification refers to Specification 406,840 and the Provisional Specification to Specification 388,173.
