OIL TANK ACCESSORY Filed Feb. 25, 1950 l? 1 9H? /V r I INVENTOR BY flail/Wiper? A TTORNEY Patented Mar. 13, 1934 UNITED STATES PATENT OFFICE OIL TANK ACCESSORY Arthur E.
Davenport, Maywood, Ill., assignor to Application February 25, 1930, Serial No. 431,202
1 Claim.
The principal object is to provide a unit assembly of simple and inexpensive construction which shall be reliable and efficient in operation and qualified for use, in a visible way, either to drain 5 underground tanks of oil dispensing apparatus or to pump oil or other liquid from drums or other containers into service or dispensing apparatus.
The nature of the invention consists in the provision of a unit assembly embodying a glass or transparent receptacle, a suction appliance or ejector, and fiuid supply and drainage connections for the receptacle.
One embodiment of the invention is illustrated in the accompanying drawing which is a view principally in central vertical section of the new assembly.
In the drawing, 5 and 6 are heads to accommodate a glass cylinder '7, the heads and cylinder being properly retained in sealing or fluid-tight relation by packing provisions 8 and bolts 9. The lower head 5 is formed with a hollow boss, tapped for the reception of a line connection 11 and for a pipe 12 ranging upwardly within the cylinder to near the top thereof where it is provided with a cowl 13.
The latter is secured in detachable relation by opposed spring-jaws 14 extending into the mouth of the pipe. The lower head also has a nipple 15 to accommodate a cock 16.
The upper head 6 is equipped with a hollow boss or nipple 17 to receive a suction appliance or fitting 18 embodying a pair of channels 19 and 20 joined by a cross-channel 21 and whereof channel 19 is provided with a nozzle 22 which discharges to atmosphere through the flaring mouth 23, across the open end of the nipple 17. Channel 20 connects as at 24 with a source of pressure and has a valve 25 and complemental valve seat 26, valve 25 normally being held to its seat under the inits seat and permit fluid under pressure to enter and be discharged from the fitting in the manner stated, thereby establishing suction conditions in the receptacle 7.
When operating to evacuate the contents of underground tanks, it will be understood that liquid is drawn from the tank into the sight receptacle via the line connection 11 and discharged into the receptacle near the top thereof, the mouth of the discharge pipe being fended from direct influence of suction action through the intervention of the cowl 13. If water is present in the liquid evacuated into the receptacle, it readily can be drawn oil through the medium of the drainage cock l6, and thereafter the oil, gasoline or other liquid can be drawn off and salvaged.
When operating as a filling device, the line connection 11 establishes communication with the drum or other container and the lubricant of other liquid may be discharged from the sight receptacle into the tank or dispensing apparatus through the nipple 15.
Having described my invention, I claim:
Means for moving liquids comprising upper and lower heads, a separable cylinder cooperating 0 therewith to form a liquid receptacle, the lower head having an axial open liquid way and a valved liquid discharge connection, the axial con-= nection being formed as opposed bosses, one of which is tapped for the reception of an extraneous connection and the other of which is tapped for the reception of a tubular riser extending substantially the effective length of the receptacle, the upper head having an axial nipple in open communication with the receptacle, and an 0 evacuator mounted on the nipple in operative relation therewith and including a portion extending on opposite sides of the nipple in spaced relation to such upper head to thereby permit the 40 fiuence of compressed air or other pressure meevacuator to be effective as a handle for lifting dium. Its stem 27 extends into abutting relathe receptacle. tion with a trip 28 terminating in a button 29 ARTHUR E. DAVENPORT. whereby it may be shifted to move the valve from
