Title: Improved brake apparatus for vehicles
IPC: B61H13/32
Filed: 1925-07-14
Abstract: 259,668. Leer, A. I. van. July 14, 1925. Force-transmitting mechanism.-In brake apparatus, more particularly for railway and tramway vehicles, in which the brake pressure is regulated by displacing the fulcrum of a lever or the point of application of a pull or push rod to a lever in the longitudinal direction of the lever, the guide for the fulcrum or point of application is so shaped as to prevent bv friction this longitudinal movement during braking. A slot 4, Fig. 2, in the power-operated lever 1 in which is displaceable a sliding shoe 5 pivotally carrying the end of pull rod 2 is in the form of an aro of a circle, the centre of which lies on the same side of the pull rod as the fulcrum of the lever 1. The other end of the, pull rod 2 is connected to the brake rod and a suspension link. Displacement of the left-hand end of the pull rod 2 from the lower to the upper end of the slot on loading of the vehicle for instance, causes the right-hand end to be shifted so as to move the brake blocks nearer the tyres. In a modification shown in Figs. 3 and 4. the shoe 5 is displaceable over a straight part 7 of the lever 1. The part 7 is wedge-shaped in cross-section and is gripped by the internal surfaces of the shoe 5 when the brake is applied. A release spring 10 is provided. In a modification, the shoe coacts with a lever which is wedge-shaped in cross-section and for which the shoa provides the fulcrum. The lever is provided with a brake rod pivoted at one end and a power rod pivoted at the other end. The shoe is rotatable on trunnions in guided shoes. The guides may be at an angle to the lever so that the brake blocks are nearer the wheels when the vehicle is loaded. In the modification shown in Figs. 7 and 9, a rod 23, pivoted at each end to shoes 25 on wedge-section parts of lever 24 is moved relatively to the levers by a connection to a wheel axle. One lever is connected at one end to the piston rod of a brake cylinder 28 and the other lever is connected at 29 to fixed point of the vehicle. Brake rods 40, 41 are connected at the other ends of the levers. The connection to the wheel axle comprises a shaft 31 connected by a crank 32 and a coupling-rod 33 to a stirrup 36 embracing the vehicle wheel axle 37. Vertical clearance is allowed between the stirrup 36 and the rod 33. The shaft 31 is connected by crank 34 and forked rod 35 to the rod 23. A dash-pot 38 in the rod 35 takes up the deflection of the supporting springs if the vehicle is loaded or unloaded with the brake applied. Stops may be provided to limit the displacement of the red 23.

Title: Improvements in or relating to the manufacture of high tensile steel
Inventor: ALLEN GEOFFREY BERTRAM
IPC: C22C38/46
Filed: 1959-05-28
Abstract: A method of testing a steel of the type referred to in Specification 886,199 during melting comprises casting a sample of the liquid steel in a prepared mould and allowing it to solidify, cooling the sample at a standard rate, usually by water-quenching, and estimating the amount of martensite in the steel by comparing the magnetic permeability of the sample with that of a known standard specimen. The amount of martensite present is directly related to the temperatures of the start of the martensite change so that the device for comparing the magnetic permeabilities (described in Group XXXVI) may be arranged to read directly in terms of these temperatures, known to vary in a predetermined way for a known change of percentage of each particular alloying element, or another arbitrary scale covering a specified range of "martensite-start" temperatures.
