Title: Improvements in coin-controlled meters
IPC: G07F15/06
Filed: 1932-08-25
Abstract: 405,363. Prepayment mechanism for meters. ALLGEMEINE ELEKTRICITATSGES., 2, Friedrich Karl-Ufer, Berlin. Aug. 25, 1932, No. 23813. Convention date, Aug. 25, 1931. [Class 27.] In a prepayment meter having a shaft arranged to be continuously driven to collect a rental or basic charge and a switch member controlled by the shaft and serving directly or indirectly to switch in and cut off the commodity, means are provided for positively removing the switch member out of reach of the shaft as soon as the commodity is automatically cut-off, so that, after a further movement of the shaft in the cutting-off direction due to arrears of rent &c., the shaft is prevented from holding the switch member in the switched-in position. A switch controlling member 2, Fig. 1, pivoted at 3 and carrying a latch 6 co-operates with a semi-cylindrical shaft 1 which is rotated in one direction by prepayment and in the other by a consumption meter and by a continuously driving mechanism independent of the load. When, after exhaustion of the inserted coins, the shaft 1 is returned to zero position so that the latch 6 can move over its flat surface, thereby automatically cutting-off the supply, if further coins are not inserted, the continuously acting mechanism drives the shaft further to collect arrears of rent. To prevent the shaft then holding the member 2 in switchedin position, a control segment 5 mounted on the shaft engages with an adjustable abutment 4 on the member 2 and, during such further backward rotation, holds the member 2 out of effective reach of the shaft 1. The number of coins due must first be inserted before the insertion of further coins are effective to allow consumption of commodity. In the construction shown in Fig. 2, the control segment 5<1> is geared to the shaft 1 so that the shaft may make several revolutions in the backward direction. The gear is in the form of a Maltese cross drive and comprises a disc 7 on the shaft 1 having a pin 8 to engage grooves 10 in a star-wheel 9 and rotate this step-by-step. The segment 5<1> is on the shaft of the star-wheel. A directly driven segment 5 may also be provided.

A telescopic umbrella frame comprising three part spokes 6, 7 and 8, a stick in at least three parts 1, 2 and 3, a main slider 12 mounted on the stick, main struts 13 having one end pivoted to a spoke and the other end pivoted to the main slider, a handle 5 inside which the enlarged ends 35 of the spokes are held during extension of the frame and a catch 'between each middle spoke part and each outer spoke part has middle spoke parts 7 of U-shaped crosssection and outer spoke parts 8 sliding within the middle spoke parts with a clearance which allows each outer spoke part to tilt within its middle part, the catch between these parts being formed by a crooked head 21 (shown much enlarged in Fig. 4) on the outer spoke part, having a nose 22 which, when the frame is extended engages in a hole 23 through the wall of the middle spoke part to lock the parts together and is held in engagement by a further part 24 and 25 of the crooked head, which projects outwards from the U-shaped middle part and is held in position to prevent tilting of the outer spoke part within the middle spoke part by a ring 26 slidable against the action of a spring 27 along the middle spoke part, the ring being movable against its spring by the inner spoke part on telescoping the frame, to release the further part of the head 24 and 25, thus allowing the outer spoke 8 to tilt within the middle spoke 7 to release nose 22 from its hole and allow the outer spoke to be telescoped into the middle spoke. To effect the extension of the ribs, the outer ends of the spokes 8 are constructed with spherical ends 35, and the handle terminates in a metal cap 37 having an annular constriction 41, which serves to lock the ends of the spokes in position by the action of a spring-actuated locking ring, so that, when the stick is extended, the spoke parts are automatically extended and engaged in the locked position, whereupon the locking ring is disengaged against the action of the spring by means of levers actuated by a button in the end of the handle and the spoke ends are then released from the grip and the umbrella stick may be fully extended. The handle is suitably fitted with an extension sleeve 47 which is partially supported by an axially slidable disc held in position by a conical spring surrounding the stick when the umbrella is extended, but which is pushed inwardly towards the cap 37, against the pressure of the spring by the end 51 of the middle stick part 2, when the umbrella is shortened.

Abstract: 1,266,511. Valves. ANDERSON, GREENWOOD & CO. 12 May, 1969 [6 Feb., 1969], No. 24099/69. Heading F2V. [Also in Division G3] A main pressure relieving valve 14 for a container T is controlled by a pilot valve P responsive to the pressure in the container and having its outlet connected to pressure responsive actuating means 16 for the main valve, a back flow preventer 22 serving to connect the means 16 to the pilot valve or to a line 24 leading to the main valve outlet if that is at a higher pressure. Fluid from the container flows through line 18 to a port 54 and the inlet 52 of the pilot valve. Normally open valve seats 44, 46 and the spacers between a polygonal closure member 90 and a cylindrical cage 40 provide communication with a chamber 66 where the fluid lifts a second closure member 78 from a seat 48 against the resistance of an adjustable spring 80 when a predetermined pressure is reached. An increased area of closure member 78 is exposed to the pressure in chamber 66 once the member has cracked open so that the fully open position is rapidly reached. Closure member 90 now engages seat 46 to shut off the supply of fluid while the space above the pressure responsive member 16 is connected to a vent 26 through the back flow preventer 22 and a line 20 to allow the main valve 14 to open. The pressure at which the valve 78 closes is determined by the spacing between the seats 46 and 48 and this spacing may be adjusted by rotating the cage 40 which has a threaded connection with the pilot valve housing. A test pressure source 116, a gauge 118 and a valve 120 are used to set the opening pressure of the valve 78, the closure member 90 then engaging the seat 44 to prevent test fluid from entering the container T. A spacer rod 104 ensures that seat 46 is open when seat 48 is closed. The back flow preventer 22 ensures that the member 16 is connected to the greater of the two fluid pressures in the lines 20 and 24 and has a shuttle valve with sealing rings for alternate closure of opposed seats. Specification 1,266,512 is referred to.
