The recess possesses at its outer end a cylindrical portion frictionally holding a correspondingly shaped portion of rod 52 the inner end of which engages the end of a tapered portion' of the recess 102 adjoining the cylindrical portion. In the construction shown the master cylinder A includes a reservoir 38 and a spring loaded one way valve 24. Piston 16 is held in the master cylinder by a snap ring 100 thus allowing the motor B to be readily detachable. The fluid pressure motor B comprises a curtain diaphragm 46 clamped between two diaphragm plates 48, 50 which house a motor control valve C. The control valve C possesses two valve seats 58, 60 which co-operate with a diaphragm and spring mounted poppet 62, the valves seats controlling the atmospheric pressure inlet and vacuum inlet respectively. In the inoperative position valve seat 60 is closed whereas valve seat 58 is open to allow air to enter chamber 54 from chamber 56 through passages 68, 72 and 74. When push rod 78 is actuated valve seat 58 is closed against poppet 62, seat 60 being opened allowing chamber 56 to be evacuated through passages 80, 66, 72 and 74. This action operates rod 52 and hence the brakes. Reaction for push rod 78 is supplied by mounting rod 52 against a resilient member 86 which abuts a boss 88 of a member 76. Slightly reducing pressure on push rod 78 closes valve seat 60 but maintains the brake actuation. To effect release of the brakes, pressure is removed from the push rod 78, spring 94 then opening the atmospheric valve seat 58.

Title: Improvements in and relating to automatic weighing machines
IPC: G01G23/18
Filed: 1934-12-08
Abstract: 426,620. Weighing-apparatus. SOC. ANON. DES ETABLISSEMENTS C. TESTUT, 8, Rue Popincourt, Paris. Dec. 8, 1934, No. 35359. Convention date, Dec. 9, 1933. [Class 143] Computing - apparatus.-An automatic weighing-scale for indicating and recording the weight and price of the commodity is provided with an auxiliary controlling mechanism for permitting the price recording device to be employed apart from the weighing mechanism. The auxiliary controlling mechanism comprises clutch devices for ensuring the locking of the weight counter in a predetermined position (zero position) and the disconnection of the motive power of the weighing scale, to permit of the printing and registering of numbers or values corresponding to operations other than those effected by the weighing scale itself. These operations may be interposed between the weighing operations without the latter being falsified or disturbed and the results of the various operations may be totalized together. As applied to a weighing scale such as that described in Specification 411,495 when it is desired to disconnect the weighing mechanism in order to register and record a sum corresponding to a commercial operation independent of the operation of the weighing scale, an actuating handle 17, Fig. 1, attached to a shaft 5 is pushed to the left into the position shown, thereby removing a pin from a groove 7 and coupling-up a clutch 8 to a shaft 12 carrying the computed price drums 13. The movement of the shaft 5 also causes a twofaced cam 14 to impart a rocking movement (first downwardly and then upwardly) to a lever 19 connected to a shaft 23. On the downward movement, the beaked ends of locking-arms 24, 25, 26 on the shaft 23 enter notches in the weight drums 29 and price drums 13 and thus lock these drums. This locking movement is only possible when the drums are in their zero positions. A lever 32 connected to the lever 25 is also raised so as to introduce a wedge 33 into a recess 34 and allow an electric switch 37 to remain open and prevent the starting of the driving motor of the weighing scale. On the upward movement of the lever 19 to the position shown in Fig. 1, the locking arms 24, 25, 26 are withdrawn (short of the initial position) to liberate the price drums but still maintain the lock on the weight drums 29, the lever 32 being received on a shoulder 31 in order to maintain the motor switch open. The price mechanism may now be set for registering and recording by means of the handle 17 independently of the weighing scale. The reverse operation of coupling the price mechanism to the weighing mechanism may be performed by first returning the price drums to zero to permit the handle 17 to be moved to the right into its original position, the lever 32 at the same time descending upon and closing the motor switch 37.
