A drum-brake with twin shoes arranged sideby-side has a balance beam between the twin shoes and the thrust member, and a common control for simultaneously adjusting all shoes. One embodiment shows the shoes mounted on carrier members 24 Figs. 2, 3, and actuated through a balance member 52 having a spherical seating in the middle to accommodate a tappet 48 driven by a rocking wedge expander 36 engaged by rollers 38 on a pull-rod 44.. The balance member 52 has an arm (55) extending over the expander body 10 and terminating in an open collar bearing on a bush held by a washer and screw (64), Fig. 1 (not shown). Nut and screw type adjuster tappets are simultaneously adjustable by gears 66 meshing with a common gear 68 and rotatable by a crown wheel 70 attached to spindle 72. Another embodiment Figs. 6...8 (not shown), provides a leading/trailing shoe arragement in which the expander and balance beam acts directly on the shoes instead of through pinmounted carriers.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B61H13/30
Filed: 1920-05-07
Abstract: 167,562. Westinghouse Brake Co., Ltd., and Rendell, A. W. May 7, 1920. Fluid-pressure.-Relates to apparatus of the kind comprising a supplementary brake cylinder for augmenting the action of the ordinary cylinder when the vehicle is loaded and to which air is admitted in an application of the brakes only when the pressure in the ordinary cylinder has reached a predetermined value. The invention consists in the provision of means for adjusting this pressure and of a particular construction of clutch by which the piston-rod of the supplementary brake cylinder is coupled to the brake rigging. The supplementary cylinder 14 has a trunk piston 20 fitted with a head or casing 22 in which is pivoted at 29 a collar 26 having a projection 27 urged into engagement with teeth 28 on the piston rod 23 by a spring pin 30. When the piston is in the release position, the collar 26 is disengaged from the rod 23 by a pin 31 which abuts against the cylinder head. The cylinder 14 is rendered operative or inoperative by a valve 7 actuated by a hand-lever 8 and arranged in a pipe 5 connected to the pipe 4 leading from the triple valve 3 to the cylinder 1. The valve 6 for controlling the supply to and exhaust from the cylinder 14 comprises a slide valve 17 in a chamber 9 connected to the pipe 5. The piston 11 of the valve is subject to the pressure in chamber 9 and to an adjustable spring 12. In operation, with the cylinder 14 cut out by the valve 7 the piston-rod 23 slides freely within the trunk piston 20 with the movement of the piston of the cylinder 1 and the rigging 24. When, however, in an application of the brakes with the valve 7 open, the pressure in the cylinder 1 and the chamber 9 of the valve reaches a value sufficient to overcome the spring 12, the valve moves from the position shown in which it connects the port 15 to the exhaust port 16 and uncovers the port 15 to the chamber 9 so that air is supplied to the cylinder 14. The initial movement of the piston 19, 20 of this cylinder enables the clutch collar 26 to engage the rod 23 and thereby connects the piston with the rigging 24. The cylinder 14 is thus operative only after the slack in the rigging has been taken up by the movement of the piston of the cylinder 1. A rod 33 with a pin-and-slot connection may be provided for the manual operation of the brakes.

Abstract: 716,740. Manufacturing gas. BRUGGEMANN, E. A. May 22, 1952 [May 22, 1951], No. 13039/52. Classes 55 (1) and 55 (2) . In a process for the complete gasification of solid fuel using steam and air with or without added oxygen as the gasifying medium, the gasification reaction is carried out under pressure and at a temperature not exceeding 775‹ C. in the presence of lime which reacts exothermically with the carbon dioxide evolved, thereby generating part of the heat required for the reaction.. The lime may be introdu:ed with the fuel into a fixed or fluidized bed, the calcium carbonate formed being withdrawn with a sufficient content of char to allow it to be regenerated to calcium oxide by passing air through the ignited mass. Alternatively, the gasification reaction and the CaO+CO 2  reaction may be carried out in separate vessels, the CaO then being regenerated in situ by means of an air-fuel mixture. In an example, 100 tons of brown coal and 220 tons of lime were reacted at 350 lbs. per sq. inch pressure with 140 tons of steam to produce 3.8 million cubic feet of gas of composition in per centages by volume of CO 2 -0.5, CO-2.5 ; H 2 -49.3 ; CH,-47.7.
