DEVICE FOR USE WHEN DRAWING OFF LIQUIDS FROM CONTAINERS Filed Sept. 14, 1931 Patented Dec. 24, 1935 U N t-T E D S TAT ES- DEVICE FOR USE WHEN DRAWING OFF LIQUIDS FROM CONTAINERS Frederick John Trevallen Barnes,'Brisbane, Queensland, Australia Application September 14, 1931, SerialNo. 562,765

1 Claim;

The usual practice, when'drawing petrol, benzine, water; or other liquids from'drums and like containers, is to raise the container to the necessary height and fit amp to the bung hole. Not

, onlyis it awkward in most cases to raise thev container but the usual arrangement of tap is such that much time 'is' lost in drawing off the liquid. The object ofthis invention is the provision of suitable means whereby the liquid may be withdrawn withoutraising the drum, without waste of liquid, without waste of time, and which permit of the tap being quickly opened and shut. Means are also provided which will ensure the delivery pipe attached thereto to be fully and quickly opened. By the use of my invention it is only necessary to remove one bung and the hole is then securely closed by my device and there is little fear of danger, which is always the case when, to hasten delivery, a second bung is removed.

In carrying the invention into effect-an adapter is formed at its inlet so that it may be screwed into the bung hole. A pipe extends through this adapter from the bottom of the drum, the outlet being fitted with a tap which is formed so that it can be quickly opened and closed. A pin or other valve may be fitted to the outlet of the tap for use in cases where a hose is attached to the outlet of the tap. An air passage, fitted with a ball check or other suitable valve, leads through the adapter from atmosphere to or near the inlet thereof. The outlet end of the air passage is formed to receive a connection with an air pump. Modifications of the invention may be provided.

In order that the invention may be better understood it will now be more fully described with the aid of the accompanying drawing, in which Fig. 1 is a side elevation;

Fig. 2 is a side elevation after certain parts have been moved;

Fig. 3 is a sectional elevation of a detail;

Fig. 4 is a top plan view of the arrangement shown in Fig. 2, and

Fig. 5 is a perspective detail of the adjustable head.

An adapter A is formed with a screw A by which it may be screwed into the bung hole in the head (preferably) of the drum A being secured by a lock nut A preferably provided with a washer A to permit of a tight joint being effected. A packing gland B is provided sothat the pipe C may be secured in the adapter A against leakage. A filter C is fitted in the coupling C of the pipe C, the lower end C of the latter being splayed. An annular air space (not shown) is provided in the adapter A around the pipe 0. An air passage (not shown) leads from" this space to atmosphere, a ball check or other valve (not shown) being provided in the passage. r The'outlet D of the'pa'ssage, to which" an air pump may be removably attached, is provided with a cap D which'isin turd-protected with a-cover D A valve E of ordinary formation 'may be'fitted to the air inlet passage for reducing pressure when desired.

A bend F or coupling is screwed to the outer end of the pipe C and a tap G, as about to be described, is screwed thereto.

The tap body G is formed with an adapter G by which it can be screwed into the bend F or a coupling on the pipe 0, a lock nut G with washer G being provided for making a tight joint. It is also formed with an outlet G, to which a hose may be fitted if desired, in which case a valve G may be provided.

A valve seat H is provided in the tap body G. The outer end of the body A carries a valve stem H a suitable packing gland H being provided. A valve H is secured on the inner end of the valve stem H and the outer end carries a head H preferably adjustable by means of the thread H on the stem H and the lock nut I-I so that the pressure on the valve I-I may be adjusted as desired. The head H pivotally carries by trunnions 1-1 the L-shaped handle lever J, to

which is pivoted at J the side bars J which latter are also pivoted to the body G by trunnions J The side bars J are coupled by a bridge piece J to simplify construction and to add strength. The lever J may be secured, as by the padlock J against improper manipulation.

The device may be made of metals and materials best suited for their respective purposes, and the details of construction may be varied as desired so long as the essential features of the invention are retained.

The drum A containing the petrol or other 4 liquid is placed on end and the plug N is un screwed from the bung hole. The adapter A is then screwed in and the lock nut Ci with washer G tightened until a tight joint is effected. The gland nut B, in the case of the arrangement shown in Figs. 1 and 2, is slackened so that the pipe C may be pushed down as far as desired or to the bottom of the drum A The tap G is turned to the required direction and the gland nut B tightened. The device is now ready for use.

The cover D and cap D are removed and a hand pump is connected to the valve D and air is pumped into the drum A after which the pump is removed and the cap D and cover D replaced.

When it is desired to draw some liquid, the lever J is turned over, thus withdrawing the valve H from the seat H. The pressure of the valve H on the seat H may be adjusted by adjusting the position of the head H on the valve stem H and locking in the altered position by the nut 1-1. This is done by engaging a suitable instrument such as 'a screw driver in the kerfed extension H on the outer end of the stem H When a hose or other pipe is attached to the outlet G the valve G may be manipulated to allow air to pass into the head of the hose or other pipe, which is then completely emptied.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that whatI claim is:

An improved device for use when drawing off liquids from containers, a tap body having an inlet end adapted to be connected'to a container, an outlet leading from the body, a valve seat provided in the body between the inlet and the out of the stem and provided with opposed trunnions, 7

an L-shaped handle lever including a shank and spaced ears projecting at right angles from the shank and pivoted on the trunnions of the head in such manner that when the valve head is in open position the ears of the handle lever are straddled about the-outer end of the stem, a lock nut on the stem adjacent the head having trunnions, side bars arranged on opposite sides of the body and having their ends pivoted to Said body and to the ears of the lever, a bridge piece integrally connecting the side bars together and arranged on the side of the stem opposite the shank of the handle lever, an apertured lug on the tap body, the shank of the lever being provided with a slot in its outer portion and adapted to engage over the apertured lug, and means for releasably locking the lever so as to hold the valve head in closed position and to. also maintain the shank of the lever and the bars parallel to each other.
