SAFETY DEVICE FOR TANKS.
Specification of Letters Patent.
Application filed'March 21, 1914. Serial No. 826,266.
To all iii/ 1.0122. 25 in {11 concern Be it known that I, HENRY L. Domes, a citizen 01" the United States, residing at Stockton. in the county of San Joaquin. and State of (.alitm-nia, have invented certain new and useful Improvements in Safety Devices for Tanks, of which the following is a specification. I
This invention relates to safety devices for tanks employed for transportating liquids which expand when the temperature thereof increases.
' t is the object oi the invention to provide a tank having a dome into which the liquid, when it ex mndsbeyond the capacity of the preventing bursting or injury of the tank.
The invention also has for its object to provide novel and improved means for venting the tank to insure a free discharge of the liquid contents thereof.
In the accompanying drawing forming a part of this specification, Figure 1 is a plan view of a fragment of the tank showing the cover of the dome removed; Fig. 2 is a cross-section of the dome and a part of the tank, showing in elevation the relief valve and other n'icchanisin. to be presently-described, located inside the dome; Fig. 3 is a side elevation of the complete tank and the car on which it is mounted, and Fig. -'-l is an elevation of the dome. partly broken away.
Referring specifically to the drawings, denotes a tank employed for transporting: oil and other liquids, said tank being mounted on a car (3 as shown in Fig. In the top of the tank an opening 7 provided with an airtight cover 8. lilounted on top of the tank, over the aforesaid opening and its cover, is a dome 9 in the top of which is an opening or man-hole 10 provided with an air-tight cover ll. The opening 10 is large enough to allow the cover, 8 to pass therethrough. To prevent loss of the covers when they are removed from their positions, they are attached to chains 12 secured to the top of the dome on the inside thereof. The
outside or: the cover 11 has a handle 13 to facilitate its application to and removal from the opening 10.
The cover 11 seats on an annular flange 14 encircling the opening 10 and it is fastened hy studs 15 and clamped down tight against the flange by nuts 16 screwed on the studs. It gasket may be interposed between the cover and the flange to make an air-tight joint. The cover 8 is fastened down in the same manner as the dome cover.
Into the cover 8, from the top thereof, is screwed a T 17 to the top branch of which is connected a relief valve 18 the outlet of which opens into the dome 9. The relief valve communicates with the interior of the tank through the T. To the side branch of the T is connected a valve 19 to the inlet end of which latter is connected an upright pipe 20 which terminates close to the top of the dome.
At 521 is indicated the usual tanlnvalve rod which extends down through the tank 5 to the outlet valve in the bottom thereof. The valve rod passes through the top of the tank into the dome and has inside the latter the usual actuating means 22. In the top of the tank is a stuilinp, box with the usual packing and gland through which the valve rod passes as shown in Fig. l. The dome 9 is also equipped with the usual relief valve 24. The tank 5 and the dome 9 are surrounded by an insulation located between the outside thereof and wooden staves 26 held in place by hoo s 27-as shown in Figs.
'3 and 4:. This insulation is not shown in F igs. 1 and 2. I
In operation, the relief valve 18 is set to open to a predetermined pressure and the rammed @c't. 3&2, this.
tank is filled as usual and the covers 8 and 11 are fastened down in place. Now, if, from an increase in temperature, the pressure and volumeof the liquid in the tank increases to a point where it opens the relief valve, the liquid and the excess pressure will pass from the tank into the dome, the dome being large enough to take care of the vol ume of liquid which might be forced out of the. tank. This liquid is retained in the dome and prevented from flowing back into the tank, and it will probably be found in good condition when the car arrives at its destination. After the tank has been emptied, the liquid in the dome can be drawn oil through valved outlets or cocks 28 opening into the tank. When liquid is drawn from the tanksome provision must be made for preventing a vacuum in the tank. This is done by removing the cover 11 and opening the valve 19, whereupon air is allowed to pass into the tank. The tank may thus be vented without removing the cover The air valve and its connections are so located 1 opening, a cover the opening and its cover,
a removable cover for the dome opening, a relief valve in the Having: described my invention, in such manner, that all versed in the art to which it pertains, may beable to build and construct it by reference to these specifications andalrawings, pertaining thereto. what I desire to secure by l'nited States Letters Pat vent isas follows:-
1. The combination of a tank having an opening, a cover for said opening, adome mounted on the tank over the opening and its cover, the top of the dome having an for the dome opening, a relief valve establishing communication between the tank andthe dome, and a valved doine into the tank.

dome, said valve having a connection With the tank cover opening into'the interior of v.the tank, and an air vent said connection. 7
3. The combination with a tank having a opening, a
valve coupled to connection, and a valved outlet from the dome into the tank.
a. The combination with a tank having a top opening, a removable cover for said opening, a dome mounted on the tank over the opening and its cover, the top of the dome haviiw an o enin a removable cover for the dome opening, a relief valve in the dome, said valve having a connection with the tank cover opening into the interior of the tank. and a valved outlet from the dome into the tank. p
