Abstract: 1,025,146. Fluid actuation of switches. FINE-BLANKING Ltd. June 4, 1964 [June 11, 1963], No. 23200/63. Heading H2B. In a system of hydraulically actuated switches leakage past cup seals is prevented by maintaining a predetermined minimum pressure in the system but means are provided to prevent this pressure from actuating the switches. The arrangement is described as applied to a system in which switches 8A, 8B are operated by cams 7A, 7B, 7C on an actuating member 6 comprising a bar connected to a piston 5 in a cylinder 4 and this piston is moved by a master piston 2 in a cylinder 1 by means of oil in a pipe 3. Flexible seals 9 are provided around each of the piston rods. The desired minimum pressure is obtained by connecting a compressed air line to a anion 10 and thereby exerting pressure on one side of a piston 12 which, being connected to the hydraulic system through a pipe 14 consequently maintains that system under pressure. The resultant tendency for the rod 6 to move towards the right, in the figure, is counterbalanced by connecting the air supply to a similar cylinder and piston unit 16, 17 the piston 16 of which bears on the opposite end of the rod. The hydraulic system is topped up by means of an oil cap 19 connected to the pipe 14 through a non-return valve 18. A second non- return valve 20 is fitted in the pipe 14 so that the piston 12 may be drawn back to accommodate additional oil.

Convention date, April 19, 1941. [Class 105] An electrical points detector has contact levers operated from the points tongue by a rotatable cam, the pivotal axes of the levers being parallel with the axis about which the cam is rotated. As shown, two curved levers 11, 12 pivoted on vertical axes at 13, 14 and acted on by spring blades 25, 26 are engageable by a cam 6 which is arranged on a vertical axis and operated from the tongue rail of the points by a connecting rod 8. When a curved lever such as 12 is engaged by the cam 6 it is first moved away against the action of its blade spring 26 to open a contact 16-18 and subsequently a contact 22 gives an earth connection through the cam. At the same time the other curved lever 11 first has its earthing contact 21 opened and thereafter on release by the cam 6 the blade spring 25 moves this curved lever 11 to close a contact 15-17. Adjustment is effected by bodily angular movement of the container case 1 which is carried on a bracket bolted to the stock rail. Several banks of curved levers may be employed to give the required number of contacts. The connecting rod 8 though joined to the tongue rail by a rubber-bushed connection permitting relative downward movement of the tongue rail on passage of a train is accurately spaced in the transverse direction by providing a metal washer accurately butting against the tongue rail.

Abstract: 911,258. Spring drums. PNEUMATIC COMPONENTS Ltd. June 29, 1961 [July 8, 1960], No. 23858/60. Class 78 (2). [Also in Group XXVIII] A spring retracted hose reel 1, Fig. 14, is automatically locked in position after extension of the hose 2A by a pawl 21, Fig. 5, pivoted at 23 on the reel for trailing in either direction over a brake drum 5 but engageable with a slot 32, Fig. 10, in a pivoted stop member 29 projecting through a gap 20 in the drum to prevent the re-winding by the spring 19 (clockwise movement) when the cable is extended and thereby relieve the operator of the need to keep the hose under tension. To free the pawl 21 for re-winding the hose, the operator extends the hose a small amount sufficient to cause disengagement from the slot 32 so that the pawl 21 falls into the gap 20 and swings to a position, Fig. 5, for trailing as the cable is rewound. The pawl 21 is free to trail (anti-clockwise) during the extension of the cable since it may drop in the gap 20 (R.H.S. of member 29) for reversing to its trailing position. A centrifugally-actuated shoe 18 engages a continuous portion of the drum 5 to control the speed of re-winding.
