DEVICE FOR DRAWING OFP LIQUIDS.

farm/0f Pdll] /Gsselez y we lfd/miv PAUL KESSELER, OF BERLIN-STEGLITZ, GERMANY, ASSIGNOR TO MARTINI & HNEKE MASCHINENBAU-AKTIEN-GESELLSCHAFT, OF BERLIN, GERMANY, A CORPORATION OF GERMANY.
Application filed May 27, 1913.
T0 all whom it may concern Be it known that I, PAUL KnssnLEn, engineer, a subject of the German Emperor, and a resident of Berlin-Steglitz, Germany, have invented certain new and useful Improvements in Devices for Drawing Off Liquids, of which the following is a specification.
My invention relates to devices for drawing oil liquids, and particularly inflammable liquids such as gasolene, and is particularly applicable to systems in which the pipe for conveying the inflammable liquid to the place of discharge is surrounded by a pipe or jacket containing gas under pressure, said gas being in communication with the body of gas contained in the upper portion of the receptacle holding the inflammable liquid, the latter being driven to the discharge point by the pressure of said gas.
The drawing-off device forming the subject-matter of my present invention has for its purpose to prevent the escape of the inammable liquid in case the device for shutting off the conveying pipe should become inefficient or leaky, without however interfering with the drawing of liquid at any other discharge points that may be connected with the same conveying pipe, as long as the shut-ofi' devices at such points are in a serviceable condition. According to my invention, this result is obtained by interposing, between the conveying pipe and the discharge pipe, an intermediate chamber which may be shut ofl' from each of said pipes by appropriate valves or equivalent devices. When said devices are in the closed position, the intermediate chamber communicates by a channel with the space of the jacket containing gas under pressure. Thus the shut-ofi' device which is nearest the discharge opening is normally exposed to the pressure of said gas, so that if the shut-oil' device of the conveying pipe should leak, the liquid contained in said pipe will be forced back by the pressure of the gas, but will not be able to escape through the outlet or discharge pipe. When the device for shutting oil the discharge pipe is moved to its open position, the first effect of such movement will be to close the channel connecting the intermediate chamber with the gas space of the jacket, and then the shutofl device of the conveying pipe is opened. The inflammable liquid can then pass from the liquid-conveying pipe through its open Specification of Letters Patent.

Serial No. 770,173.
shut-oil device into the intermediate chamber which at that time is disconnected from the gas space of the jacket, and can then pass into the discharge pipe through the open shut-oil' device 'of said pipe. When the drawing of the liquid is discontinued, the shut-off device of the liquid-conveying pipe is closed first, and then the intermediate chamber is placed in communication with the gas space of the jacket, whereupon the shut-off device of the discharge pipe is closed, which shut-ofi' device is nearest the outlet.
A typical example of my invention is shown in the accompanying drawings, in which- Figure 1 is a vertical section of the improved apparatus, and F ig. 2 is a detail end view of one of the valves or shut-off devices. The receptacle containing the gasolene or other inflammable liquid is not shown in the drawings, but l designates the liquid-conveying pipe which dips into the liquid contained in said receptacle. The drawing shows only the upper end or upper section of said pipe. The pipe 1 is surrounded by a jacket-forming pipe 2, the space between the two pipes communicating with the upper portion or gas space of said receptacle, so that the gas under pressure contained in said receptacle above the liquid, will also fill the pipe 2, around the pipe 1. Of course, the drawing shows only the upper end or upper section of the pipe 2. At the top, the pipe 2 is enlarged to form a casing 3, surrounding, at a distance, the upper portion of the liquid-conveying pipe 1 as well as an intermediate chamber 5 interposed between the pipe 1 and the discharge pipe 4. The interior of the intermediate chamber 5 communicates, under normal conditions, with the gas space or jacket of the pipe 2, as by means of a channel 6, preferably located at the upper portion of said chamber. The shut-oil' device for the liquid-conveying pipe 1 is shown as a valve 7 having a stem 8 around which is coiled a spring 9 one end of which bears against the valve and the other against a suitable stationary part, as a portion of the casing 3, said spring tending to seat or close the valve 7. The valve seat is formed by an annular flange 10 provided at one end of the perforated plug 11 which is screwed into the casing 3. The valve 7 has spaced longitudinal ribs 12 1n nection of the first-named chamber with the discharge conduit and also its connection with the gas chamber in such a manner as to close one connection when the other is open and vice versa, and means for operating the said valves successively.
5. The combination of a liquid-conveying conduit, a discharge conduit, a chamber interposed between said conduits, a gas chamber normally communicating with the firstnamed chamber, a Valve controlling the connection of the first-named chamber With the liquid-conveying conduit, another valve. having a limited movement relatively to the first-named valve, and controlling the connection of the first-named chamber' With the discharge conduit and also its connection with the gas chamber, means for operating said valves successively, and separate means tending to return each of said valves to its closed position.
6. The combination of a liquid-conveying conduit, a discharge conduit, a chamber interposed between said conduits, a gas chamber normally communicating with the firstnamed chamber, valves controlling the connection of the first-named chamber With the liquid-conveying conduit and with the discharge conduit respectively, and means for operating said valves.
7. The combination of a liquid-conveying conduit. a discharge conduit, a chamber intel-posed between said conduits, a gas chamber normally communicating With the firstnamed chamber, valves having a limited movement relatively to each other and controlling the connection of the first-named chamber with the liquid-conveying conduit and with the discharge conduit respectively, and means for operating said valves successively.
In testimony whereof I have signed this specification in the presence of tWo subscribing Witnesses.
