Y., as signor to _General Electric Company, a corpo» ration oi New York Application September 2B, 19%, Serial No. ‘345,379 5 Cla. My invention relates to‘ fluid» dispensing de vices and more particularly to gasoline dispens ing 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. 5 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 l 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 ñexible hose, at the 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 pro jected into the fluid stream. This light follows the duid stream into the tank and is there re ?lected 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, ìs,--l. In a gasoline dispensing apparatus, the com-_ bination 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 sep arated from said fluid lstrearri and arranged to project light into said stream parallel to the axis end of Vwhich a nozzle is provided for projectingl _ of said hose. 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 20 .practically no light reaches the interior of the tanks even in the day time. In accordance with my invention l'. provide a lamp at the end of the hose which is attached to the pump and sep arate this lamp from the fluid stream completely 25 so as to avoid any fire hazard. Iv then provide a light~reiiecting surface on the inside oi the hose to prevent absorption of the light emitted by this lamp and transmitted down along the fluid . stream into the tank. so ‘ In the accompanying drawing I illustrate a standard gasoline dispensing pump l having an 40 2. Ina gasoline dispensing apparatus, the com bination of a flexible hose, a nozzle at one end thereof, a rigid >connection at the other end hav ing an inlet passage at an angle to said hose [email protected] connection and a transparent portion at right angles to the fluid stream in said hose, and a light in back of said transparent portion ar ranged to direct light through said transparent , 25 portion into said fluid stream. , 3. In a liquid dispensing apparatus, the corn bination 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 ar ranged at an angle to the said hose, a lamp cas-a ing mountedyon said connection and separated indicator 2 and an outlet pipe having a T-mem from thehose by a transparent wall, and a lamp ber t attached to the end thereof. The T-mem mounted `in said casing and arranged to project ber 3 is vertically arranged having attached light into said hose. to its lower end a iiexilole textile or rubber hose thaving a nozzle t and a valve t attached to the end thereof. » d. In a liquid dispensing apparatus, the com bination of> a ilexihle hose, a rigid connection , ' - At the other end of the r-membex- r attach a for said hose provided with an inlet >passage at an angle to the axis of said hose, a transparent 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 iiuidtíght by a lens itl. The hose itself wall at4 right angles to the axis of said hose, means i‘or projecting light into said hose through said transparent wall, and a reflecting lining within said hose for preventing the absorption ' is provided on the inside with a smooth light reiiecting 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. oi’ the said light.

In a gasoline dispensing apparatus, the com bination of _a ilexible hose, a nozzle at one end thereof, and a light'at the other end of said hose arranged‘to project lightinto said hose and through the gasoline therein.
