The receptacle andI)an are secured to each other by meansof an L-shaped |)ipe, the short end ofwhich passes through the bottom ofeach. With a washer between the twobottoms, the pipe is well soldered so asto make water tight joints. The pipe extends out horizontallybelow the pan, and is provided with afaucet at its projecting end.
