4 Claims.

This invention relates to a drum valve and
faucet especially adapted to use in dispensing
liquids from closed containers, such as drums, and
it consists in the constructions, arrangements
and combinations herein described and claimed.
It is a particular object of the invention to
provide a valve in which an automatic control of
the vacuum and air pressure conditions within
a closed container may be readily controlled and
eliminating the need Jfor the usual vent valve
ordinarily required in containers of the kind
specified, in order that a liquid may be dispensed
from the container or drum.
It is also an object of the invention to provide
a dispensing valve in which the dispensing faucet
or spigot may be fully housed, when in inopera
tive position, so that it lies susbtantially flush with
the wall of the drum or container, avoiding the
possibility of being struck, which eventually
might cause a leaky valve.
It is a still further object of the invention to
provide a dispensing valve and faucet of simpli
fied construction, of few moving parts, and which
may be wholly constructed from plastics.
Additional objects, advantages and features of
invention will be apparent from the following de
scription considered in conjunction with the ac“
companying drawing, wherein
Figure l is a longitudinal sectional View through
a valve and faucet constructed in accordance
with the invention, in dispensing position.

position.

threaded for a purpose to be explained.
The opposite end of the barrel is open and is
provided with an annular iiange Il for mount

admitted to the chamber 44 by way of the vent

pass into the drum by way of the port 23. Pas
sage of air in this manner obviates the need for
special vent valves in the drum to insure proper
ñow of liquid through the faucet. The operation
may be continued until the required pressure has
been attained, which will vary, depending upon
the viscosity of the liquids to be dispensed.
