Addendum to patent 292086.

Patented in the German Empire on January 23, 1914. Longest duration: January 27, 1928.

The invention relates to a further embodiment of that protected by patent 292086 System for storing and transferring petrol and other volatile liquids using water that is drawn off during the tap is fed to the gasoline storage tank through a standpipe under pressure, into which approximately at the level of the ceiling of the gasoline storage tank a closable water drainage pipe and in approximately the same height so that the pressurized water supply pipe opens, its shut-off valve is connected to the shut-off valve of the water drain pipe that when open Water inflow the drain pipe is blocked, and

that when the water drain is open, the inlet pipe is blocked and the standpipe is empty.

In the present innovation, these two valves are combined in a three-way valve, and the dispensing tube of the storage container is also provided with a three-way tap through which it can be closed or connected to a ventilation pipe. The two taps are coupled and designed so that

ι. in the rest position all lines above the ground are empty and the dispensing pipe closed so that the system is secured against fire, frost and external violence,

2. In the tap position, the tap pipe is ventilated so that tapping of water is excluded is,

3. Filling petrol or the like into the

Storage container proceeds by siphon action and is therefore interrupted as soon as the transfer line comes into contact with the outside air, whereby the pipe empties immediately. When the storage container is full. will that Filling interrupted by a float that opens an air valve on the transfer line.

Since the handling is limited to turning a single handle, so is the system is also secured against the dangers of incorrect handling.

The new system is illustrated in the drawing in one embodiment, namely represent:

Fig. Ι a schematic sectional view of the entire system,

Fig. 2 sections along the lines AA and BB of Fig. 1 on an enlarged scale,

3 is a schematic view of a detail on an enlarged scale, and FIG

4 shows schematic sectional views of the taps in their various positions.

The standpipe 1 is connected to the pressurized water line 2 and the drain line 3 through the tap a. One line is closed by the cock α when the other is opened. The standpipe 1 is attached inside the storage container 4 and the transfer pipe 5 and collar pipe 6 extending therefrom. Above the storage container 4, the standpipe 1 is surrounded by an overflow pipe 7.

closed, which has connection to the drain pipe 3 at 8.

In the new device, the dispensing pipe 10 connected to the transfer pipe 5 is provided with a tap b , by means of which it can be closed or connected to a ventilation pipe 11 and the outlet pipe 12 or to one of the two pipes 11 and 12 4 indicated. The taps α and δ are coupled by a rod 24 so that both change their positions when the handle 23 is rotated. The related positions of the taps are shown schematically in Fig. 4, namely:

Position I. The tap α connects the standpipe 1 to the water drain 3 and closes the pressurized water supply line 2, while the tap b closes the dispensing pipe 10 and that

ao outflow pipe 12 connects to the ventilation pipe 11.

Position II. The cock α connects the upright tube 1 with the pressure water line 2 and closes the water discharge pipe 3, while the cock b the dispensing tube 10 to the ventilation pipe 11 and the outflow pipe 12 connects. Position III. The cock α connects the upright tube 1 with the water discharge pipe 3 and closes the pressure water pipe 2, while the cock b the dispensing tube 10 connects to the outflow pipe 12 and closes the vent pipe. 11

Position IV. The cock α closes all three pipes 1, 2, 3, in that the dotted hole cannot connect the lines ι and 2 at different heights, while the cock b connects the dispensing pipe 10 to the ventilation pipe 11, but the outlet 12 locks.

In position I the system is at rest; the pipes are above the ground emptied, and the dispensing line 10 with the tap δ is closed.

If you have turned the taps a and b into position II by means of the handle 23, the tapping is thus initiated. The cock a closes the water drain pipe 3 for the standpipe 1 and then opens the pressurized water pipe 2. Now the water rises in the standpipe 1 and causes the stored flammable liquid, e.g. B. gasoline, rises through the transfer tube 5 and expels the air through the ventilation pipe 11 and the outlet 12. After the gasoline has been completely emptied from the storage container 4 and the transfer line 5, the water in this line will be level with the upper edge of the standpipe 1. The connection with the ventilation line 11 prevents water from being drawn off at the lower-lying outlet pipe 21 through a possible occurrence of a siphon effect in the line 5-12-20-21.

If the handle 23 is turned further into the position III, the filling of the storage container 4 from the transport container 22 is initiated by a siphon effect in the line 21-20-12-δ-10-5. The cock α closes namely in the position III for the standpipe ι the pressurized water pipe 2 and then opens the water drain pipe 3. At the same time, the cock b closes the vent pipe 11 and the outlet 12 for the transfer pipe 5 and then opens it again. As soon as the water, which is in the standpipe up to its upper edge, sinks, the siphon effect occurs safely, since all air is expelled from the line 21-20-12-6-10-5 by the gasoline during the draw-off because of the Movement resistance has risen a little in the ventilation pipe above the tap δ.

The siphon effect and thus the filling of the storage container 4 from the transport container 22 is interrupted as soon as the taps a and δ are turned to position IV, whereby the tap δ connects the dispensing pipe 10 to the ventilation pipe 11 and closes the outlet pipe 12. The cock α closes the water discharge pipe 3, without the pressurized water pipe 2 to open, and the fuel sinks down in the transfer tube. 5 A condition for this is that the taps have assumed position III for so long that the standpipe ι has emptied of the water in it up to the level of the water drainage line 3.

To ensure this, the standpipe 1 is provided with a tubular float 25. This blocks the rotation of the taps a and δ from position III to position IV until the standpipe 1 is emptied up to the level of the water drainage line 3. For this purpose, the float 25 moves the pin 27 up and down in the sleeve 28 by means of a lever 29 equipped with the counterweight 30. As long as the float 25 has not sunk, the rotation of the handle 23 and thus the valves α and δ from the position III to the position IV as a result of the arm 31 striking against the pin 27 is prevented.

Taps a and δ are returned to normal closed position I from position IV. The taps a, b are always turned in the same direction. A locking device is used to prevent the turning of the taps a and δ in opposite directions.

A float 13 in the storage container 4 is connected through a pipe 14 to the lower end the tie rod 15 provided with a counterweight 16 is connected. On this one is

Stop disk τη arranged, which opens a provided at the upper end of the transfer tube 5 valve 18 as soon as the float 13 has reached its lower position shown with dotted lines. By opening the valve 18, the siphon effect in the transfer tube 5 is interrupted; the lines 21, 20, 5 are thus emptied immediately when the storage container 4 is filled with gasoline.
The arrangement of the float rod 15 in the standpipe 1, the lower mouth of which is constantly under water, eliminates the inconveniences of a connection between outside air and gasoline through the float tube.
