RECEPTACLE CONTAINING VOLATILE 0R INFL AMMABIiE LIQUIDS SUCH AS IBENZENE AND OTHER HYDROCABBONS.

Application filed August 15, 1524. Serial No. 132,325.

To'aZZ whom it may concern: 7

Be it known that we, MARTINUs AnmANUs MEIJER and RICHARD VOM FELD, citizens 'of' Netherlands and Germany, respectively, re-

siding at The Hague, .Netherlands, and

Brunswick, Germany, respectively, have invented certain new and useful Improves ments in Receptacles Containing Volatile or Inflammable Liquids Such as Benzene and 10 Other Hydrocarbons (for which we have applications filed in German Jan. 12, 1924,

and July21, 1924:), of Whic the following is a specification.

a Our invention relates to improvements in rece tacles containing volatile or inflam;

mab e liquids such as benzene and other hydrocarbons, and more particularly in' safety valves provided in connectionwith such j receptacles for avoiding the loss of gas and inflammatiom'of the liquid, and for compensating the variations of the volume of gas when filling the receptacle or tapping liquid therefrom, and the expansion or contractioncaused by variations of temperature. The object of the improvements is to provide a valve system comprising two valves or groups of valves disposed so that one valve or .group of valves opens when the pressure within the receptacle exceeds the normal, and that the other va ve or group of valves opens when the said ressure is beldw the normal, the last name of valves controlling the admission of air or gas. Preferably the receptacle is connected. with a receptacle adapted to take up the gas expelled irom the storage tank andto supplythereto gas in case of low pressure.

The same reference characters have been used in all the views.

a In the drawing,

Fig. l'is a sectional elevation showing the improved valve,

tion I and two, concentric walls b an b.

" T h m PIQ iQQQ be ween the tubular valve or group Fig. 2, is a sectional plan view taken'onportion 1 and the wall b is divided by a horizontal partition 2' and radial partitions d into compartments k is, k and k. Valves n and m are disposed in the concentric chambers, and the sectional valve oasin'gs are constructed so that all of the valves open in an upward direction, these valves n and mbeing adapted to 0' en or close pas sages 'w and w between t e compartments k, k and 7c. The chambers 70 communio0 cate through passages s with the semi-cylindrical chamber is provided, between the left hand part of the walls 6 and 6 which chamber communicates through a tubular part v with the air or with a supply of a no suitable gas. The chambers in communicate through an opening? with the semi-cylin-' drical chamber k provided between the right hand parts of the said walls I) and 12 which chamber communicates either 70 throughan opening t with the outer air, as shown in Fig. 1, or through a tubular part u with a receptacle for storing the gas expelled firom the receptacle 9', as is'shown in Fig. 3. The chambers 70 and k communichamber is", the opening '7', the chamber is and the opening t or the tubular member into the atmosphere or a storage receptacle1'8 v If the ressure is below the normal, gas is drawn in through the tubular part q), the; chamber is, the o enings 8, the chamber 7 the openin w, t e chamber 70, the open? ing 9 and t e tubular member Z into the reptacle g. Under both conditions the ves m or n are raised from their seats.

We claim:

In a valve construction of the class specified, the combination with a container for highly volatile and combustible liquids, of an annular chamber divided into upper and lower portions and having a central pipe communicating respectively with the lower chamber and the upper chamber, the two 90 chambers being provided with valves and valve seats controlling communication between the said upper and lower chambers, the upper chamber also communicating with a supplemental chamber having an outlet and the lower chamber communicating with a supplemental chamber having an inlet,

permitting exit of gas from the container said suyplementary chambers respectively and admittance of gas thereto,

In testimony whereof we have hereunto setour hands.

MARTIN US ADRIANUS MEIJER. RICHARD VOM FELD.
