The nature of my invention consists in an improved apparatus for containing and drawing oils and other liquids capable of returning the drip or overflow to the tank or reservoir, and of filtering the same, as Well as the liquid, when drawing, and also of measuring the liquid in the act of drawing.

Let A represent a tank, can, or other reservoir for containing a supply of oil or other liquids kept on hand, to be of any desired construction. I

A pump, B, is placed in this tank or reservoir, reaching nearly to the bottom Within the same, and extending upward therefrom to the desired height.

At the top of the pump is a chamber, O, to serve as a standing fountain for holding a quantity of the liquid when pumped up from the tank or reservoir. sired form.

If it is desired to measure the liquid as drawn a measuring-scale, a, is applied to this standing fountain.

Under the spigot or spout is a sink or dripreceiver, D, to catch anyr drip or waste of the liquid, and it may serve to support the vessel into which the liquid is being drawn. This sink or drip-receiver is constructed so as to convey and return the drip to the tank or reservoir A.
