Abstract

811,489. Brake transmitting mechanism. SVENSKA AKTIEBOLAGET BROMSREGU, LATOR. July 26, 1957, No. 23777/57. Class 1.03 (1). In an improvement in brake apparatus, for railway vehicles, in which the leverage may be varied by means of links 13, 14 connected to brake levers 1, 2 to give lower and higher leverage respectively, the link 13 is connected to lever 1 through a lost motion connection which may be taken up by a movable abutment 20 mounted in housing 17 for lower order leverage, the extension 18 of link 13 having two equal diameter portions 18a and 18b, located either side of a reduced diameter portion 18c and sliding in cylindrical portions 17c, 17d of housing 17, the housing 17 having an enlarged portion 17b integral with, and between, portions 17c, 17d surrounding extension portion 18c and abutment 20. The abutment 20, pivoted at 24 to housing portion 17b, is connected by a pin 26 and pivot 25 to a diaphragm 22 clamped in place by a lid 21, a spring 27, between the diaphragm 22 and lid 21, biases abutment 20 to the operative position, the diaphragm being flexed to withdraw the abutment by vacuum through an opening in lid 21. In Fig. 5, not shown, the abutment is biased to the operative position by a. spring and withdrawn by fluid under pressure. Specifications 426,779, 768,599 and 782,225, [Group XXVI], are referred to.
