Abstract
1,011,442. Sampling liquids. LEA RECORDER CO. Ltd. Oct. 21, 1964 [Oct. 23, 1963], No. 41738/64. Heading B8N. A liquid sampling device comprises a table 1 for supporting a number of sample containers 4 adapted to be successively filled via a rotary supply line 9 and a feed pipe 13, means 20, 21, 26 for emptying the pipe prior to filling each successive container thereby to ensure that the sample is representative of the liquid into which the pipe dips at the time when the sample is taken. The supply line 9 is in the form of a trough carried at one end by the output shaft 7 of a clockwork timer motor 6, the other end of the trough extending over funnel member 3 to which the containers are secured. The feed pipe 13, which is of a flexible material, is adapted to enter the inner end of the trough and form part of a pumping device 14 before being connected to the source of liquid to be sampled. In operation, after winding the timer, the latter is started which slowly rotates the shaft 7 until a lobe on a cam 11 contacts a switch 12 which energizes a motor to drive the pump 14; the pump comprises three rollers 18 mounted on a disc 17 and adapted to compress the resilient pipe 13. As the motor spindle rotates a pin 21 fixed to a disc 20 on the spindle strike a reversing switch so as to cause the pump to run in a direction to feed liquid into a container. When the container is full a pin 22 on a lever 23 adjustably mounted on the spindle, strikes the reversing switch so as to thereby pump the liquid remaining in the pipe 13 back to the source until, finally, the pin 21 strikes a lever 25 on a switch 24 to stop the pump motor. The pump motor may be energized by a battery or from the mains via a suitable transformer.
