DEVICE FOR CONTROLLING THE DELIVERY OF LIQUIDS FROM TANKS 0R VESSELS.

Specification of Letters Patent.

Application filed December 22, 1908. Serial No. 468,845.

To all whom it may concern Be it known that we, ALFRED ARTHUR QUICK and CHRISTOPHER JAMEs SPENCER, subjects of the King of Great Britain, residing at 46 Hilton street, Clifton Hill, driver, and 285 Swanston street, Melbourne, electrician, respectively, Victoria, Australia, have invented new and useful Improvements in Devices for Controlling the Delivery of Liquids from Tanks or Vessels, of which the following is a specification.

Our invention relates to an improved apparatus for controlling the delivery of liquids from a supply tank or vessel to a receiving can, and refers more particularly to a means for controlling the quantity of kerosene oil delivered from such tanks or vessels.

Though our invention is hereinafter described as relating to the control of the delivery of kerosene oil from a supply tank or vessel, it will be well understood it is equally applicable to the delivery of other liquids, and in this specification the term oil will be held to include such other suitable liquids,

WVith the supply of bulk kerosene oil, as at present practised, the oil is sent out in transport tanks from which it is delivered to the customers in measured cans adapted to contain a predetermined quantity. 7

Our invention consists of a tap device which is attached to the supply tank and is so constructed as to permit of its being operated only when connected to the receiving can or vessel, such connection serving to open the tap for the delivery of the liquid, the said tap device being closed by the operation of disconnecting it from the receiving vessel.

In order that our invention may be better understood we will now proceed to describe the same with reference to the accompanying sheet of drawings in which Figure l is a side sectional elevation of our invention showing its connection to a receiving can or vessel adapted to contain a measured or predetermined quantity of liquid; and Fig. 2 is detail view of certain parts thereof.

A is the receiving can or vessel, the top of which is formed with a lip or spout A for the purpose of conveniently discharging the liquid therefrom. There the top part joins the body of the can A, there is disposed a collar A provided with a cross web A havlng a screw-threaded socket A the aforesaid collar A and the screw-threaded socket A constituting the means whereby the tap device which is attached to the supply tank may be connected to the whenever it is intended to draw liquid therefrom as hereinafter described. For this purpose the outflow pipe B from the supply tankB is attached to an inlet pipe C on acasing C within which the tap device is inclosed. Casing C is formed with a flange C which bears upon collar A a Washer C of rubberized leather or other suitable material being interposed therebetween. The casing C is also formed with a downwardly projecting ring C which is inserted within the central opening in vessel A produced by the collar A and the said ring C is provided With holes C for the flow of the liquid as herein after described. Ring C is provided with a swinging trigger C which is utilized to lock casing C to vessel A on being forced under collar A Casing C extends upward in the form of a cylinder C within which works the device for opening and closing the tap for admitting the flow of the oil, sa id device being arranged in such manner that the means supplied for opening the tap and allowing of the flow of oil cannot be operated unless said casing is connected to the receiving vessel. For this purpose within the upwardly extending cylinder C is pro vided an internal cylindrical casing D having a hollow downward extension D passing out through the bottom of the casing C. The extension D is formed at its lower end with a plunger D having a seat or washer of rubberized leather or other suitable material which engages the opening in the bottom of the casing C and thereby forms a valve or tap by which, when the same is lowered, the oil or other liquid is admitted to the interior of the receiving vessel through the holes C while, when it is raised, the flow of the liquid is cut oil. Within the casing C and surrounding the internal casing D is a helical spring E which bears upon the flange receiving vessel A,

D at the top, so that when said casing D is depressed, its downward movement is against the tension of the said spring. Plunger D is designed for movement in a vertical direction, which movement is effected through the agency of a dome F, (shown in detail in Fig. 2) having one or more slots or grooves F cut in the sides thereof, said dome F being adapted to fit within the internal casing D and being provided with an upwardly projecting sleeve F that projects through the central opening in the top of the outer casing C Sleeve F is provided with an operating handle F by which it may be rotated. Within the dome F fits a hollow cup Gr having feathers G (shown more particularly in Fig. 2), corresponding with the slots or grooves F and adapted to engage the same, so that the same rotary motion may be transferred from the dome F to the cup G irrespective of their vertical positions. This cup G is provided with a downward projection Gr having its pointed lower end G screw-threaded and adapted to engage threaded end G engaging the socket A in the cross bar or web A Thus, in operation, dome F is depressed against spring E, so as to insert point G of extension G into socket A and to engage the slots F with the feathers Cr in the cup G; rotation of the drum by means of its handle will then occasion a similar movement of said cup. As the rotation of cup G continues, the screwthreaded end 6 engaging the socket A the cup G, and with it the internal casing D, will be drawn downward also, thereby compressing the spring E. At the same time, the plunger D on the downward extension D is forced away down from the opening in the casing C, thereby allowing of a flow of oil through the holes G into the interior of the vessel. A from the supply vessel B. Instead of the screw G we may provide an equivalent device such as an eccentric or cam or the like by which the plunger D is forced downward by the connection of the casing C with the vessel A. Simultaneously the trigger G is forced outward by the plunger D and is caused to engage under the flange A thereby locking the casing C on to the top of the vessel A, while the filling operation is proceeding, and preventing any tampering or interfering with such filling operation.

For the purpose of allowing of the outflow of air, during the filling operation, and of any surplus liquid, the downward extension G is drilled with a passage Gr having parts G communicating with the interior of vessel A, the passage G extending upward into communication with the interior of the cup G. lVit-hin cup fits a plunger H hav ing packing rings H and provided with an upwardly projecting hollow rod H which extends through the sleeve F and is connected to a pipe J which communicates with the interior of the supply vessel B above the surface of the oil. The plunger H is also formed with a valve H" which is adapted to cover the passage G in the downward extension G Ports H are provided communicating with the hollow rod H Thus the air within the vessel and any surplus liquid is allowed to flow upward through the passage G in the downward extension G into the cup G, thence through the ports H into the hollow rod H and finally through the latter and the pipe J back into the supply vessel, while the valve H prevents back flow.

In operation, it will be seen that the tap device is opened and closed by the raising and lowering of the downward extension D of the inner cylindrical casing D, and the disengagement and engagement of the plunger I) from' and with the opening in the bottom of the casing C. This is effected by the screw-threaded point G engaging the socket A and it is only by the casing C being connected in this way to the receiving vessel A. that the oil can fiow thereinto from the supply vessel 13. Consequently, each filling operation of the receiving vessel A must be effected by manipulating the handle F As soon as the vessel A is filled, the flow is automatically out off by the oil reaching the same level in the hollow tube H or the pipe J as that within the vessel B. The casing C may then be removed and either connected in the same way to another similar receiving vessel, or to the same when emptied.

The device is all inclosed, as shown, so that it cannot be interfered or tampered with, and, as a further safeguard, the screw G may be incased within a cylinder, (not shown) which passes over the socket A when in engagement therewith.
