between the legs 23, and finally through the bottom opening of the shell.

This valve is designated 25 in Fig. 1, 25a in Fig. 3, and 25c in Figs. 4, and 6.

5 The means for initially retaining the valve in open position in Figs. 1 and 2 consist of a resilient metal yoke or inverted U-shaped member 26 which extends diametrically across the cup forming the baflie, and has hook. legs 2'7 which extend beneath the valve 25 so as to normally prevent a spring 28 from forcing the 'valve .on to its seat 29.

The closing plug 30 for the drum, is employed to actuate this valve retainer, and it will be ob-' served that for this purpose, the threaded skirt 31 is slightly longer than usual, whereby when the plug is screwed into the threaded portion 32 of the top ring, its skirt will move the diametrical portion of the retainer downwardly as indicated.

in dotted lines, whereby the. hook legs will be removed from beneath the valve and the spring 28 will force the latter to its seat.

From this it will be understood that while the receptacle is being initiallyfilled, the retainer 26 will prevent thevalve from closing, but when the sealing plug 30 is attached, it will function to move the retainer so thatthe latter will release the valve and the valve will seat. From that time on, the spring 28 will seal the device against refilling, but of course, the spring has insuflicient strength to prevent liquid from flowing outwardly when it is pumped in the usual way.

It is preferred that a gasket 33 be used in connection with the p1ug'30 to close any exit from the air grooves 16 to prevent any outward seep ageof oil through these grooves while the re ceptacle is in transit. l

If preferred, as shown in'Fig. 3, the valve 25a may be initially held off its seat by a bow spring 26a which is positioned beneath the valve and has legs 27a resting on the lower portion of the shell. In this case, the valve will be spaced slightly from the bottom 22a. of the baflle, and will be formed of magnetic material, and when magnetic force is exerted upwardly through the opening in the top of the device, the valve 25a-will rise slightly and the legs 27a, under their own resiliency, will spring toward one another so that the retainer 261; will drop into the'pipe 10a, and then the spring 28a will force the valve to its seat, when the magnetic force is released.

As shown in Figs. 4 to 6 inclusive, the valve can be initially retained off its seat by distortable arms or pins 40 which project inwardly from the wall of the shell and initially support the valve 250. In this event, thebafile 22b will be rotatably arranged within the shell, and consequently, when the baffie is'rotated about the axis of the shell, itslegs 23a will strike the pins and bend the same out of valve obstructing position; as indicated in'Fig. .5. Then the spring 281) will act to seat the valve.

The baflle in this instance can be rotated by any suitable magnetic tool inserted through the top of the device, or the baflie may have its cylindrical wall provided with inwardly pressed protrusions 220 that may be engaged by any special turning tool built for the purpose.

As illustrated in Fig. 6, any of the forms of the devicedescribed may be employed in .connection with a conventional suction pump provided the latter is equipped with an improved adapter. As illustrated'in this figure, a conventional pump 50 has a suction pipe 51, and this pipe is provided at its lower end with a nut 52 that is externally threaded so that it may be screwed into the threaded portion 32 of the top ring. Another threaded collar 53 is secured to the base portion of the pump and bears on the sealing gasket 33, after the sealing plug is withdrawn from the latter through the pipe 10 and past the valve 250.

In all of my constructions, as the valve 25,

25c, 250 is supported by the shell or cup 8 secured to the top 17 of the drum, the down pipe 10, 10a may be made of a thin tin tube which may be of inexpensive and light construction. Furthermore, the arrangement of the valve at the top of the drum eliminates the necessity of employing a suction valve in the pump, as my valve is arranged sufficiently close to the pump to serve as a suction valve for the same. Moreover, as the down tube does not have to carry a valve, and therefore'may be made of light material, it is unnecessary to anchor its lower end to the bottom of the drum where it extends into the sump, (Fig. 6).

In the last mentioned figure, the construction is also such that the pump may face in any direction relatively to the drum. As advertising matter is usually placed at one side of such a drum, it is desirable that the pump face in that direction. In accordance with my invention, the member 52 can be screwed downwardly to a desired depth within the ring 32, and then the pump may be turned to face the pump in the desired direction. Afterwards, the nut 53 can be screwed down on to the gasket 33 to make a tight joint and to prevent the pump from accidentally moving out of proper position relatively to the advertising matter on the drum. In other words, my parts 51, 52 and 53 are of such construction relatively to the drum, that they in eifect form a swivel connection for securing the pump to the drum.

From the foregoing it is believed that the various forms of the invention which have been illustrated may be clearly understood, and it is manifest that changes may be made in the details disclosed, without departing from the spirit of the invention, as expressed in the claims.
