Title: Improvements in fluid pressure operated brakes
IPC: B60T13/24
Filed: 1930-06-27
Abstract: 350,270. Fluid pressure brakes. BOSCH AKT.-GES., R., 4, Militarstrasse, Stuttgart, Germany. June 27, 1930, No. 19626. Convention date, June 27, 1929. [Class 103 (i).] Relates to control mechanism for fluid pressure brakes in which a lever is connected to the valve, the operating pedal or lever and an auxiliary piston subject to the brake cylinder pressure and including a spring or other variable resisting force in such a manner that the valve after being opened by the pedal is closed by the piston and the spring or other force reacts on the pedal to indicate the braking pressure. In an arrangement for a compressed air brake, Fig. 1, the lever c is connected to the valve h by the link and lever f, g, to the pedal a by a link h to a suspension link or lever n and to a piston m subject to the pressure in the pipe i<1> leading to the brake cylinder. A spring o is attached to the link n. The upper end of the lever has limited movement by means of an eye d, through which passes a fixed pin. When the pedal is depressed the lever c swings about pivot n<1>, the pressure valve is opened and the pressure established in the cylinder l of the piston m and the brake cylinder moves the piston m to the left, the lever c swinging back about the pivot b<1> and thus extending the spring o and closing the valve. The spring and the piston m react upon the pedal proportionally to the braking pressure. Upon further movement of the pedal this operation is repeated with a resulting increase in the braking pressure. When the pedal is returned the exhaust valve is similarly operated to reduce the braking pressure. The link n may be dispensed with and the spring o be connected directly to the lever c. The spring may be replaced by a cylinder the air in which is compressed by the movement of the lever c or as shown in Fig. 7 the variable resistance may be provided by a second cylinder s<1> connected as is the cylinder l to the pipe i leading to the brake cylinder. In this case a light spring t may be provided in the cylinder l so that the lever c first swings about the pivot m<1>. The application to vacuum brakes is also described.

Abstract: 753,788. Fixtures for supporting gauges or workpieces during checking. WOODWORTH CO., N. A. July 5, 1954 [July 10, 1953; Oct. 26, 1953], No. 19673/54. Class 106 (2). A checking fixture comprises workpiece and gauge holder, each having a bearing for supporting a shaft carrying the workpiece or gauge, the bearing being split, enabling it to be tightened to the desired degree on the shaft and contacting the shaft at three or more spaced points. In the gauging assembly illustrated, a shaft 40 connected to a chuck 34 is supported in split bearings 48, 50 having tightening screws 58, 60 and set screws 62 limiting the degree of tightening. Oiled felt is carried in the bearing gaps 52, 54. A collar 72 on the shaft 40 is held against one end of the bearing 48 by a bowed spring washer 74 acting against a collar 64 adjustably secured on the shaft. The collar 64 serves for rotating the shaft and the workpiece 12. Gauges 26, 28 are supported on arms 90 having split bearings 92 engaging a fixed shaft 82. Collars 98, 100 are adjustably secured on the shaft 82 and spring washers 104 take up end play. The arms 90 carry pins 110 which engage stops 112, 114 on the collars 98, 100 to limit free rotation of the arms. In order to ensure satisfactory support conditions when the shafts are comparatively loose in the untightened bearings, radial slots may be formed at opposite sides of the bearing axis and remote from the tightening screws to render the bearing halves flexible at the region of the slots. Alternatively, the bearing gap may be made of substantial width, or the bearing surface may be relieved to give three axial ribs forming supports for the shaft.
