Abstract
1,007,201. Delivering measured quantities of granular material. ALFA-LAVAL CO. Ltd. Sept. 18, 1964 [Sept. 18, 1963], Nos. 36732/63 and 27148/64. Heading B8N. [Also in Divisions F2 and H2] A control means for actuating a metering member 1 of a material delivery apparatus, such as described in Specification 903,997, comprises a pneumatically-operated piston 2 connected via a one-way drive R to the metering member 1 so that continuous movement of the piston effects intermittent movement of the metering member, a valve 4 for controlling the air pressure acting on the piston and actuated automatically for a predetermined number of times and a manually actuable means for initiating the operating cycle. The metering member may have four vanes defining four measuring chambers as disclosed in the above Specification; a sprocket 6 being secured rigidly to a shaft carried by the member. The piston 2 is mounted in a cylinder 3 and connected to one end of a chain 11, the other end being secured to a stationary member. A sprocket 9 runs on the chain and mounted on a link connected to a lever 7 freely pivoted on the shaft; a pawl 8 for engagement with the teeth of the ratchet is mounted on one end of the lever, the other end being loaded by a spring. In operation, upon pressing a button a switch MS1 is actuated to start an electrically driven timer adapted to periodically actuate a switch MS2 which energizes a solenoid to open the valve 4. The piston, which is then connected to a source of vacuum, rises and thereby, via the pawl and ratchet, rotates the metering member one quarter of a turn.
