July 23, 1935. v A, PETRO I 9 AUTOMATIC AIR VENT Filed Jan. 25, 1935 "INVENTUR' M 62%;;
"WWMZLZZA/ ATTn-RN EZY Patented July 23, 1935 UNITED STATES PATENT orrica AUTOMATIC AIR VENT Anthony Petr-o, New Rochelle, N. Y., assignor to Petro Petroleum Corporation, New Rochelle,
N. Y., a corporation This invention relates to an air pressure releasing device for bottles or like liquid containers, whereby air is admitted to the bottle causing the contents of the bottle to be freely discharged therefrom without bubbling.
A further object of the invention is to provide a valve in the air inlet-tube which is adapted to be held closed by the pressure caused when the tube is inserted in the bottle, thereby preventing the contents of the bottle from entering the tube as it is inserted therein.
A further object of the invention is to arrange the tube securing means externally of the bottle thereby leaving the neck of th'ebottle free from unnecessary obstruction.
In the accompanying drawing:
Fig. 1 is a top plan view of the device;
Fig. 2 is an enlarged side elevation of the vent tube partly in section showing the same as applied I to a bottle the latter being shown in dotted lines.
The numeral i denotes a tube constructed of any-suitable metal, the body portion of which is made tapering, the large end adapted to extend down in the bottle A terminating close to the bottom of the bottle. The upper end of the tube a is bent over upon itself forming a substantially inverted U-shaped portion 2 which loops over the neck of the bottle, with the upper end of the tube extending downwardly along the side of the bottle. Secured to the open end of the overhanging portion 2 of the vent tube l is a member 3, the cylindrical bore 5 of which is alined with the opening in the portion 2 of the vent tube l. Leading from the bore 4 of the member 3 is an alined cylindrical bore 5 of a smaller diameter than the bore 4 thereby forming at their juncture a valve seat 6. Located in the bore i is a ball I acting as a valve to normally close the upper open end of the vent tube 5. As shown in Fig. 2, the ball valve 1 normally rests upon the valve seat 5 as the vent tube is inserted in the bottle, and inasmuch as the end 2 of the vent tube extends downwardly, any pressure exerted as the tube is lowered in the bottle serves to increase the pressure upon the ball, thereby preventing the contents of the bottle from entering the vent tube i which in turn would prevent the ingress of air into the bottle.
An inclined pocket 8 extends laterally from the bore 6 which houses the ball i, said pocket serving to receive the ball I as it is unseated when the bottle is turned downwardly in the act of discharging the contents of the bottle, thereby permitting air to enter the bottle causing the contents thereof to freely discharge therefrom.
The numeral 9 denotes a substantially U- shaped clamping member secured to the member 3. The outer more or less resilient prongs ill-Hi of the clamping member are adapted to partly encircle and grip the neck of the bottle 5 preferably on the outside thereby leaving the outlet of the bottle as free from obstruction as possible.
As noted in Fig. 2 the body portion l of the vent tube is 'at an angle with respect to the it vertical axis of the bottle, which serves to throw the lower open end of the vent tube toward the outer edge of the bottom to insure a quick inlet of air into the bottle as it is tipped downwardly in the act of discharging the bottle. 15
To increase the area of the outlet of the bottle the upper portion of vent tube l where it leaves the neck of the bottle is flattened as at H.
In the use of this device which is particularly useful in discharging lubricating oil from bottles 20 or like containers, the vent tube 5 is held in a vertical position whereupon the ball 7 will rest upon the valve seat 6 closing the outlet end of the vent tube as it is passed downwardly into the bottle, the gripping member passing over the 25 extreme upper flanged end of the bottle and seating itself beneath the flanged end to firmly secure the vent tube against displacement when the bottle is tipped in the act of discharging its contents. As heretofore pointed out as the bottle so is tipped the ball l is unseated and falls into the pocket 8 opening the air intake end of the vent tube I permitting air to enter the bottle, causing the contents of the bottle to freely discharge therefrom. 35
The preferred embodiment of the invention is disclosed in the drawing and set forth in the specification, but it will be understood that any modification within the scope of the claimed invention may be made in the construction without 40 departing from the principle of the invention.
