UNITED STATES PATENT OFFICE.
CHARLES P. ROSS, OF SEATTLE, WASHINGTON.
VENT FOR LIQUID-RECEPTACLES.
To all whom it may concern:
Be it known that I, CHARLES P. Ross, a citizen of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Vents for Liquid-Receptacles, of which the following is a specification.
This invention relates to vents for liquid receptacles; and its object is the provision of a device of this character which will admit air into a receptacle while liquid is being drawn therefrom, at other times preventing the admission of air and thus obviate the vo-latilization of the liquid except when it is being dispensed.
The invention consists in the features hereinafter described and more particularly set forth in the appended claim.
In the drawings, Figure 1 is a longitudinal vertical section of a vent embodying the present invention; and Fig. 2 is a transverse vertical section of the same.
The reference numeral 5 designates a portion of the wall of a liquid receptacle provided with an aperture to receive the body of the vent. Said body is preferably con structed with a circular peripheral wall 7 which, as illustrated, is formed with a tapering lower portion which is eXteriorly screwthreaded to be screwed into the receptacle wall. The lower end of said body which v extends into the receptacle is open while the upper end is closed by a head 8. Subjacent to said head is a tube 9 extending diametrically through the body and desirably having its ends 9 protrude outside of the body to afford convenient means whereby the body may be grasped by the operator in screwing same into a receptacle or withdrawing it therefrom. Int-eriorly of said body and in the top of said tube is a vent opening, or orifice, 10 which is ground or Specification of Letters Patent.
Application filed July 22, 1912.
Patented Aug. 19,1913.
Serial No. 710,806.
otherwise formed to fit circumferentially about and furnish a seat for a ball valve 11.
The above described parts constitute the vent proper and supplementary thereto I provide withinthe body and below the tube 9 a whistle to audibly indicate when the vent is admitting air into the receptacle. Such whistle is comprised of a pair of diaphragms 12 and 12 provided with centrally disposed apertures 13 and 18 and which will generate a sound when air is flowing into the receptacle to replace any liquid being taken therefrom.
In operation the withdrawal of liquid from the receptacle to which the vent is applied will tend to create a vacuum within the vessel and thereby establish a difference between the air pressure existing outside the receptacle to that within the receptacle and such unbalanced pressure acting against the ball valve will serve to raise the latter to admit air into the receptacle. IVhen the withdrawal of liquid ceases, the valve is closed by gravity.
This invention, it may be said, is designed only for use with receptacles containing liquids under little or no pressure.
WVhat I claim, is
A vent for liquid receptacles comprising a body open at its lower end and a closure upon the upper end integral therewith, a centrally arranged boss formed in the cover, an open ended air tube extending diametrically of the body and spaced from the top and provided with an opening arranged centrally thereof, and a valve in said opening limited in its unseated position by engaging the boss.
Signed at Seattle, Washington.
