WILLIAM H. MCNUTT, OF NEW YORK, N Y., ASSIGNOR TO WILLIAM C. GILEB, TRUSTEE,
. OF NEW YORK, N. Y.
LOCKED STRAINER-TUBE.
Specification of Letters Patent.
Patented Aug.
To all 'whom it may conce-rn:
Be it known that I, WILLIAM H. MCNUTT, a citizen of the United States, residing in New York city, in the county of New York and State of New York, have invented certain new and useful Im rovements in Locked Strainer-Tubes, of which the following is a specification.
This invention relates to means for locking in the plug member that is movable for filling pur oses, yet which will permit the operation o a -relief valve, and will also permit a fusible member to be blown out upon the ccurrence of an abnormal temperature, for the i purpose of preventing an explosion.
In the accompanying drawings illustrating one embodiment of my invention, Figure 1 is a Iplan view ofthe device. Fig. 2 is a vertica section through a portion of a receptacle with the locking member attached thereto. Fig. 3 is a view similar to Fig. 1 with the locking device in open position.
The locking member itselfconsists essentially of a lever movably secured at one end referably by a hinge while the other end as locking means for securing it in place by a suitable lock, such as a pad-lock.` At the middle ortion of the lever is an opening surroundin the relief valve of the safety device, and a so surrounding a fusible blow-off device. In the construction shown this member comprises a lever 5 hinged at 6 to an apertured member 7, that is attached to, or may form a part of a container. The other end of the lever is shown as secured in position by an eye 8 secured to the member 7 passin through an opening 9 in the lever, throng which eye is 'passed a pad-lock 10. The lever is shown as provided with a central opening 11 larger than a relief valve in the closure bushing, and larger than a central portion of the bushing carrying the relief valvel and secured thereto by a fusible connection such as solder.
The a ertured member7 is shown as having a threa ed bore 12 into which is screwed a threaded bushing 13 having a fiange 14 engaging) the top of the member 7. The flange may e polygonal for engagement with a wrench. The bushing has a bore closed at the to by a disk portion 15, being secured to the ushing by a ring of solder 16. It will be observed that the opening 11 in the lever is larger than this ring permitting the disk to be blown out when the solder is melted by heat, by the gas in the container.
The disk 15 is provided Withseveral openings 17 closed by a valve 18, whose stem 19 projects through a central hole in the disk; a coil spring 20 serving to kee 'the valve normally closed. The valve bein the disk, its free o eration wnot be interfered with by the ever because of the large opening 11. The bushing 13 is also shown as provided with a closure at its lower portion containing minute iiame proof openin s. The bore of the bushing is threaded at t e lower end and a diaphragm 2 screws therein which contains a number of holes. Before this diaphragm is screwed in, one or more disks 21 of wire auze or the like are inserted. These wil serve to revent the passage of flame. through the bus ing.
The lower end of the a )ertured member 7 is shown as provided wit 1 aninternal flange 22 on which rests the ange 23 of a closed tube 24 that is provided with minute Hameproof openings. A threaded ring 25 .is screwed down through the bushing onto this flangebefore the bushing 14 is placed in osition, and securely locks the apertured tu e in position.
The apertured member 7 is shown as closing the top of a tube 26 that may be secured on top of a suitable tank or container. When it is desired to lill the container, the
ad-lock lis unlocked and removed and the ever swung to open position. This will permit removal of the bushing 14, when the gasolene or other explosive liquid can be poured down into the apertured tube from which it will flow into the vessel. Then the lashing is screwed into position, and the lever locked in its roper position. This will prevent remova of the bushing. But the relief valve 1S is free to permit escape of vapor or gas that may generate in the tank. Upon the occurrence of fire that would heat the ring of solder, and the generation of a large volume of gas and high pressure, the disk forming the top of the bushing will be released and blown out, which action is ermitted by a large opening in the lever. ut the apertured diaphragm in the bushing is still locked in position that will eHectually prevent back liring into the container.
Having thus described my invention, I claim:
1. In a device of the character described, the combination of an apertured member, a closed tube having minute dame-proof opensmaller than ings therein and secured in said opening, a
