Q. How is the Penberthy automatic injector made t

A. A is the tail pipe, B B the steam jet, C the suction tube, D D the combining tube, E the delivery pipe, H the overflow valve, and K the cap of the overflow pipe.

Q. How would you work this ?

A. Open the suction valve full; also, the valve in the steam pipe. When water appears at the overflow, gradually close the suction valve. As the steam rises, open the suction valve until the injector takes all the water.

Q. What is the difference between a Hancock Inspirator and an ordinary injector?

A. The inspirator is a double apparatus, one-half of which is a lifter, and the other half a forcer; the lifter drawing the water and delivering it to the forcer, which delivers it to the boiler, at any steam pressure, vnthout adjustment. An ordinary injector is a single apparatus, requiring adjustment for the varying steam pressures.

Q. How high should an inspirator lift water?
