VENTILATING ATTACHMENT FOR TANKS. u

SPECIFICATION forming part of Letters Patent No. 749,802, dated January 19,` 1904.

Application filed September 15, 1902. Serial No. 123,441. (No model.)

To all wiz/0711, it 77H07/ concern:

Be it known that I, CHARLES NOLLER, acitizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Ventilating Attachment for Tanks, of which the following is a specification.

MyV invention relates to automatic air-regulators for beer-tanks. I

The object of my invention is to provide an automatic air-regulating device for beer-tanks invention consists of an air-receiver provided with two-detachable heads with openings therein controlled by valves hinged to said detachable heads, one of which is employed to permit the escape of air or gas from the tank and the other to permit the suction of air into the tank. n A short tube `vertically projecting from the under side of the air-receiver is provided at the end with a iiangebase, which adapts it to be fastened to a tank by means of screws or said end to be screwthreaded on the outside, permitting it to b e attached to a tank by screwing it into an opening therein. lIn the top of the air-receiver a gage and sight-opening is provided for the purpose of permitting the contents in a tank to be gaged through the said air-regulating device.

In order to enablelothers skilled in the art to which my invention most nearly appertains to make and use the same, I will now proceed to describe its construction and operation, reference being had to-the accompanying drawings, forming a part of this specification.

Figure 1 represents an end view of my device. Fig. 2 represents a sectional view of Fig. 1, taken on dotted line 2 2, Fig. l, looking from a point toward the left in the direc- C is a detachable head provided with a'n airy outlet opening E and is inserted and held in the end of one of the tube extensions B by means of a screw-thread whichis provided 0n a portion of the periphery thereof and engaging a corresponding screw-threaded portion of the interior walls of the said tube extension. F is a valve employed to control the opening and closing of said air-outlet opening E and is attached on the outside to said head C by means of a pin H inserted through a hole in the tongue extensions S of said valve F and supported in the lugs Gr on the upper outside portion ofsaid head C. l

I indicates a valve employed to control the opening and .closing of the air-inlet opening E in detachable head D and is attached to the insideof said head D in the same manner as valve F, the head D being inserted and held in the tube extension B in the same manner and by similar means as head C.

J indicates a short vertical tube extension from the under side of the air-receiver A, being integral therewith, and is provided with a Harige-base K, adapting it to be fastened to a tank O by means of screws Q, inserted through holes R in said base K and secured into said tank, or the end of said tube J may be provided with screw-thread L on the outside thereof, which adapts it to be attached to tanks by inserting the same in a screw-threaded opening in said tank, in which case the iange-base K may be dispensed with.

' M indicates a detachable screw-cap employed to closea sight and gage opening in the top of the air-receiver A and is provided with a wrench-seat N thereon.

TOO

and air-outlet openings E, as shown in Figs.

l and 2. r[The valve-seats of the air-inlet and air-outlet openings in heads C and D are slightly obtuse and on an angle, as shown in Figs. 1 and 2, which permits of close contact of thc hinged valves F and I in closing said openings through the gravity of their own weight except when the same are overcome by the suction and escape of air into and from the tank.

The operation of my device may be eX- plained as follows: /Vhen liquid is turned into the tank O through the faucet P by means of a hose-coupling or feed-pipe connected therewith, (not herein shown,) the air thereby accumulating in the tank rises up into the airreceiver A, closes the valve l in the head D, and opens the valve F in head C, passes out, and escapes through the air-outlet opening E therein. Gas accumulating from liquid undergoing' or passing' through the stage of fermentation in the tank, such as beer or other malt liquors, operates the valve F and escapes from the tank in the same manner as air, as previously described. Then liquid is drawn from the tankthrough the faucet P or other means connected with said tank, the suction caused thereby in the air-receiver closes valve F in head C and opens valve I in head D, permitting air to be( drawn into the tank through the air-inletfopening E in said plug l), and thereby facilitating the flow of liquid through' the faucet P or other means of drawing same.

The air-inlet opening in head D may be smaller in size than the air-'outlet opening in head C, as shown in Fig. 2, which permits and regulates a requisite supply or current of air to be drawn therethrough into the tank by suction when liquid is being drawn therefrom.

By making the heads C and Ddetachable renders the interior of the air-receiver A to be easily and conveniently cleaned of any forma- Ition that may be deposited therein from vapor arising from liquid in the tank.

With my device the liquid in the tank is always kept intact, and all tendency of dust, dirt, and undesirable foreign mattei' collecting therein is obviated.

Having thus described my invention, what 1 claim as new, and desire to secure by Letters Patent, is-

1. The combination in ventilating attachment for tanks, of an air-receiver provided with a sight and gage opening, the detachable heads having an opening therein, and valves controlling the same attached thereto, sulstantially as described and for the purposes set forth.

2. In ventilating attachment for tanks, the combination with the air -receiver, the detachably-attached head provided with an airinlet opening and the detachably-attached head provided with an air-outlet opening therein, valves attached to said heads, the sight and gage opening in said air-receiver, means for attaching said Ventilating attachment to tanks, all connected and operated, substantially as described and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES NOLLER.
