My invention relates to fluid dispensing devices and more particularly to gasoline dispensing pumps for lfilling the tanks of automobiles.
One object of my invention is to provide an improved light for illuminating the inside of the tank which is being filled.
For a better understanding of my invention, together with other and further objects thereof, reference is had to the following description, taken vin connection with the accompanying drawingand its scope will be pointed out in the ,appended claims.
'I'he well known gasoline dispensingI pumps, which are now used atY automobile service staa tions, are equipped witlra exible hose, at the end of Vwhich a nozzle is provided for projectingl into' the tanks of automobiles. With this equipnl ment it is practically impossible for an attendant to see where the iiuid level is in the tank since stream into the tank.
In the accompanying drawing I illustrate a standard gasoline dispensing pump l having an indicator 2 and an outlet pipe having a T-member t attached to the end thereof. The T-member 3 is vertically arranged having attached to its lower end a iiexilole textile or rubber hose thaving a nozzle t and a valve t attached to the end thereof.
At the other end of the r-membexr attach a casing l having therein a light t and a reflector 9. The casing 'l is provided with an opening coinciding wth the end of the T-member, which is closed iiuidtght by a lens itl. The hose itself is provided on the inside with a smooth lightreiiecting surface preferably of white synthetic rubber so that the light projecting from the lamp and'reilector will not be absorbed by the hose lbut such light as might tend to escape from the fluid stream will be reflected back into the stream and will follow lt into the tank.
In operation the lamp t is lightedwhen the pump is started. The light fluir projected by the lamp is gathered by the reflector and is projected into the fluid stream. This light follows the duid stream into the tank and is there relected by the walls of the tank so that the level of the liquid in the tank becomes clearly.visible.
What I claim as new and desire to secure by Letters Patent of the United States, s,
l. In a gasoline dispensing apparatus, the combination oi a flexible service hose provided with a nozzle and valve, a feed connection to said hose, and a lamp mounted at said feed connection separated from said fluid lstrearri and arranged to project light into said stream parallel to the axis of said hose.
2. Ina gasoline dispensing apparatus, the combination of a flexible hose, a nozzle at one end thereof, a rigid connection at the other end having an inlet passage at an angle to said hose connection and a transparent portion at right angles to the fluid stream in said hose, and a light in back of said transparent portion arranged to direct light through said transparent portion into said fluid stream.
3. In a liquid dispensing apparatus, the cornbination of a flexible hose, a nozzle at one end thereof, a rigid connection at the other end of said hose provided with an inlet passage arranged at an angle to the said hose, a lamp cas-a ing mountedyon said connection and separated from thehose by a transparent wall, and a lamp mounted `in said casing and arranged to project light into said hose. d. In a liquid dispensing apparatus, the combination of a ilexihle hose, a rigid connection for said hose provided with an inlet passage at an angle to the axis of said hose, a transparent wall at4 right angles to the axis of said hose, means ior projecting light into said hose through said transparent wall, and a reflecting lining within said hose for preventing the absorption oi the said light.
5. In a gasoline dispensing apparatus, the combination of a ilexible hose, a nozzle at one end thereof, and a light'at the other end of said hose arrangedto project lightinto said hose and through the gasoline therein.
