1 Claim.

The present invention relates to novel and useful improvements in an emergency tank unloading device and more especially pertains to an attachment permitting a quick unloading of the contents of a tank as in an emergency.

The principal objects of this invention reside in providing an attachment which may be quickly applied to the discharge opening of tanks or tank cars and the like, for the purpose of effecting a sealing engagement therewith to thereby permit the safe and expeditious removal of a controllable part of the contents of the tank.

Additional objects reside in the provision of a device of the character set forth in the preceding paragraphs, which shall be of lightweight and extremely portable and adaptable nature; which may be quickly and easily applied to a variety of types of tanks and will accommodate itself to a plurality of sizes of discharge orifices in the same; which shall be so designed as to be capable of effecting a satisfactory and quick sealing engagement with and removal from the discharge openings of tanks; and which shall be so constructed as to permit the withdrawing of a portion of the contents of tanks from time to time as the same may be required.

These, together with various subordinate objects of the invention, which will later become apparent as the following description proceeds, are realized by my invention, one embodiment of which is illustrated by way of example only in the accompanying drawings, and wherein:

Figure 1 is an elevational view showing my device applied to a tank discharge opening, a portion of the tank being shown in section; and,

Figure 2 is a vertical central sectional view through the detachable inlet means of my device.

Referring now more specifically to Figure 1 of the accompanying drawings, it will be seen that my device indicated generally at In is associated with a portion l2- of a tank or a tank car or the like, having a threaded discharge opening l4 adapted for the reception of a conventional type of fluid discharge control means, not shown.

The attachment I is shown held tightly pressed into internal seating and sealing en-- gagement with the discharge opening [4, by means of a pair of timbers or blocks or the like, l6, associated underneath a pair of handles 18 extending from my device, for the purpose of wedging the appliance tightly against the said discharge opening.

Attention is now directed more specifically to Figure 2 for an understanding of the structural features of the attachment. A tubular pipe 20 of any desired size or material is provided, upon one end of which and embracing the same is secured a conical member 22 of some material of a resilient or deformable nature, such as rubber, plastic, wood or the like, it being understood that the conical member 22 is preferably rigidly secured to the end of the pipe 20. A tubular, hollow, cruciform shaped member 24 is provided, with a pair of vertically disposed and aligned tubular arms 26 and 28 adapted to slide upon a portion of the tubular shaft 20, and with a pair of laterally and oppositely extending tubular arms 30 and 32, into which are detachably screw threaded the handle members l8 above referred to. An annular plate or disc 34 is interposed between the base of the conical member 22 and the adjacent end of the cruciform member 24, to serve as a support for the deformable member, and to transmit pressure from the support member 24 to the conical member 22 in a manner to be set forth hereinafter.

A short length of suitable flexible hose 36, is attached upon the outer extremity of the tubular shaft 20, preferably in tight engagement with the lower end of the tubular arm 28, being retained upon the shaft by adjustable clamps 38 or the like.

As shown in Figure l, the tubular member 36 is detachably secured by means of suitable clamps 4!! to a manually operable flow controlling valve 42, which may be attached to the inlet end 44 of any suitable fluid suction or dispensing line.

From the foregoing, it is believed that the manner of operating my device will be now apparent. When it is desired to withdraw all or part of the contents of the tank I2, as when a tank car is left for unloading upon a siding in a position where the customary unloading fixtures are not accessible thereto, the usual sealing plug or discharge fitting is removed from the bore 14, and the conical member 22 forced inwardly of the exposed orifice, being tightly held therein in firm seating and sealing engagement by means of the pressure applied to the handles 18, as by means of timbers l6, blocks, any suitable type of jack or the like. The suction line .4 may then be connected by means of valve 42 with the flexible hose 36, and through manipulation of valve 42 all or part of the contents of the tank l2 may be readily withdrawn, and this operation repeated as often as desired as with filling a plurality of containers from the tank 12.

I claim as my invention:

An emergency drain device including a conical plug adapted for insertion of its reduced end into the threaded bore of a discharge orifice in the bottom of a tank, a tubular pipe extending axial- 1y of said plug and having an adit at the re- 5 duced end thereof, a supporting member surrounding said pipe adjacent the enlarged end of said plug, means engaging said supporting member for forcing said conical plug into said discharge orifice, a flexible conduit connected with said pipe adjacent said supporting member, and a valve secured to the end of said flexible conduit, said supporting member including a hollow cruciform body forming pairs of aligned arms, said pipe extending through a pair of said aligned arms and said means comprising a pair of handles, each detachably secured in one of said other pair of arms of said body.
