\ Application filed February 20, 1902. Serial No. 94.896. (No model.)

To aZZ whom it may concern.-

Be it known that I, ARTHUR S. TUTTLE, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Valves, of which thefollowin g is a specification The invention relates to such improvements; and it consists of the novel construction and combination'of'pa rts hereinafter described and subsequently claimed. I,

' Reference may be had to the accompanying drawings,and the reference characters marked thereon, which form apart of this specification.

Similar characters refer to similar parts in both figures.

Figure l of the drawings'is a central vertical longitudinal section of a valve embodying my invention applied to a water-main'for the purpose of relieving the main of accumulations of air. Fig. 2 is a view showing theairchamber provided with a plurality of valved outlets.

My invention relates to automatically-operating valve connections between media of different densities or under difierent pressures, and my invention contemplates the use of a valve adapted to be operated in one direction by reason of such diiferences in density or pressure and in the opposite direction by means of a buoyant weight under suitable conditions.

An important object of my'invention is to automaticallyrelieve mains carrying water or other liquids from air and other gases which collect at pipe-line summits.- Accumulations of air in such mains often greatly reduce their capacity and are asource of error when metering the supply.

Referring to the drawings, 1 represents a Water-main, and 2 an air or gas chamber located above the same, in communication therewith through the coupling 3. This gaschamber has one or more outlet-openings 4 in its upper side, each adapted to be closed by a puppet-valve 5, such openings preferably communicating with the atmosphere. These puppet valves are preferably made buoyant, whereby they are adapted to be automatically closed by flotation upon liquid contained in the air-chamber 2 before such the stem 9 of one of the valves'5. '7 is preferably connected with the valve-stem pressure Within the chamber.

liquidreaches a height'in said chamber such that it can escape through the outlets 4. These valves being open, it will be seen that gaseous matter can freely ascend from the main into the air-chamber 2 and escape thence through the openings4. As the main becomes relieved of its gaseous contents its liquid contents will gradually rise into the aircrurned at 8 upon a fixed support and operatively connected in any known manner with The lever 9 by a loose connection such that the buoyant Weight is free to rise to the limitpermitted by the stop lo'without operatingthe connected puppet-valve, the closing of each valve being accomplished by' its own buoyancy. When the valves have thus been closed, the air-chamber 2 becomes a pressure-chamber, the internal pressure tending to maintain said valves in a closed position without regard to the presence .of air in said chamber. As the air accumulates in said chamber, however, the liquid recedes therefrom, causing a gravity-induced movement to be imparted to the weight 6 and lever 7, which movement-is transmitted to the valve 5, connected with said lever, and serves to open said valve against the force of the internal pressure.

-When a plurality of puppet-valves are employed, one or more of them may be thus connected with the buoyant weight 6, the opening of the connected valves by the gravityiuduced movement of the buoyant weight serving to relieve the pressure within the chamber 2, permitting the other valve or valves to open by gravity. The float being wholly contained within the air cha'mber is caused to rise and fall solely by reason of its 'cha mb'erand automatically cause the buoy-' v buoyancy and weight Without regard to the The several parts are so constructed and'a'rrangedthat the buoyant weight has-a very limited movement and only operates to open the buoyant valve after the air-chamber has become approximately full of air. As the air escapes from the chamber and the Water rises in the samethebuoyant weight will be given its maximum elevation by flotation long before the water rises suificiently in the air-chamber to close the buoyant valves by flotation. A considerable period is thus permitted to elapse between successive operations of the apparatus, as the valve is not opened until the chamber is approximately full of air and is not closed until the chamber is approximately full of water.

My improved valve will operate automatically to relieve the main from gaseous matter and efiectively prevent the escape of liquid matter therefrom, and this without regard to the pressure maintained in the main. It will also admit air in case of a break in the main, which for steel pipe lines is a safeguard against collapse.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a pressure-chamber provided with an inlet leading from a denser medium, and in its upper portion with an outlet leading to a rarer medium; of a buoyant valve for said outlet adapted to be maintained closed by the pressure within said chamber; a buoyant weight in said chamber; and connecting mechanism for causing said valve to be opened at certain times in opposition to said pressure by said buoyant weight, and permitting said valve to remain open until closed by flotation independently of the buoyant weight, substantially as described.

2. The combination with a liquid-conducting main; of agas-chamberlocated above said main in communication therewith and provided with a gas-outlet; of a buoyant valve for said outlet adapted to be closed by flotation upon said liquid as the same rises in the gas-chamber; a buoyant Weight; and means whereby said Weight is adapted to act upon said valve by a gravity-induced movement only.

3. The combination with a pressure-chamber provided with an inlet; and a plurality of outlets; of a like plurality of valves for the respective outlets adapted to be separately closed by flotation and maintained closed by the pressure within said chamber; and abuoyant weight in said chamberoperatively connected with one of said valves and adapted to open the same by a gravity-induced movement in opposition to said pressure, substantially as described.

4:. The combination with a pressure-chamber provided with an inlet, and an outlet in its upper portion; of a buoyant Valve adapted to close said outlet; a buoyant weight and connected lever located within said chamber; and a loose connection between said lever and valve whereby a gravity-induced movement only of said buoyant weight is transmitted to said valve to open the same in opposition to the internal pressure, substantially as described.

In testimony whereof I have hereunto set my hand this 23d day of January, 1902.
