' PIPESI'ONE, 'MINNESOTA FILLING NOZZLE Application filed August 14, 1929. Serial No. 385,946.

This invention relates to a filling nozzle adapted to be employed for a variety of purposes, but more especially-useful as a gasoline filling nozzle.

An object of the invention is to provide a filling nozzle of simple, novel and improved construction which will include an illuminating device capable of affording suflicient light at the mouth of a tank or other min tainer while being filled to enable an attendant to readily see when the tank or other container is full, to thus avoid overflow of liquid, as, for example, gasoline.

Other objects of the invention will become apparent as the specification proceeds, it being understood that the disclosure herein is merely illustrative and intended in no way in a limiting sense, changes in details of construction and arrangement of parts being 2 permissible so long as within the spirit of the invention and the scope of the claims which follow.

In the accompanying drawings forming a part of this specification,

Fig. 1 is a view, partially in section and partially in elevation, of ,a filling nozzle in which the features of the invention are incor.

porated; 1

Fig. 2 isa detail sectional view of a portion of the filling nozzle of Fig. 1, disclosing the nozzle applied to use;

Fig. 3 is a fragmentary sectional view ofa filling nozzle of modified construction made in accordance with the invention; and

Fig. 4 is a sectional view taken as on line 44 in Fig. 3.

Referring more particularly to Figs. 1 and 2 of the drawings, the filling nozzle there shown is'of a general construction as ordinarily utilized at gasoline filling stations, in-

cluding a body portion or grip part 10 and an outlet tube 11. The body portion or grip part 10 is secured in any suitable manner, as represented generally at 12, to a hose 13 leading from a source of liquid supply (not shown), such, for example, as gasoline, and

.the outlet tube 11 is screwed. into said portion or part 10, as denoted at 14, so that a liquid passage 15 extends from the hose 13 and through the bodyportion and outlet tube of except insofar as my novel filling nozzle desaid valve element 17 upon its seat. An actuating lever 20 for the valve stem may be pivoted, as at 21, upon the body portion of the filling nozzle and guided, as at 22, by a guard 23 suitably supported upon said body portion 10.

The elements so far described may be of any ordinary or preferred construction, and

form no specific part of the present invention,

sirably includes a quick and ready means for allowing and shutting off a flow of liquid through said filling nozzle.

A bent tube 24, as disclosed of relatively rigid material, is secured in the body portion 10 in any convenient manner, as at 25, and the'lower portion of said tube 24 suitably supports a casing 26 having a lamp socket 27 removably receiving a lamp bulb 28, said casing and lamp bulb desirably being arranged centrally of the outlet tube 11 in spaced relation to the wall thereof, and said lamp bulb preferably being situated not very far distant from the outlet end of said outlet tube. A center lead wire 29 to the lamp, from a source such as indicated generally at 30, is insulatively situated within the bent tube 24, while a ground lead to the socket and from the source includes the tube 24 as shown. A lamp housing, denoted 31, which is situated about the lamp bulb 28, is threadedly arranged upon the casing'26, as indicated at 32, to be removable therefrom. Said lamp housing is desirably positioned wholly within the filling nozzle outlet tube 11 in spaced relation to the wall thereof, and the outer portion of the lamp housing is arranged to allow passage of light from the lamp when lighted into and out of the. outlet end of the filling nozzle. K disc 33 of transparent mica suitably seals the lamp housing .31 at the outer side of the bulb 28, as indicated generally at 34:, to thus preclude the possibility of flashing acombustible liquid, such as gasoline, being dispensed by the filling nozzle. Numeral 35 represents an electric switch suitably supported upon the fillingnozzle and arranged to control the flow of current to the lamp.

In Fig. 2, numeral 36 represents a tank or other container having a mouth or filling opening 37 into which the outlet tube 11 of the filling nozzle of the invention is inserted, as when the nozzle is applied to use in an operation of filling said tank or other container. When the filling nozzle is so situated and the electric switch 35 is in closed position to cause thelamp within the filling nozzle to be lighted, rays of light pass outwardly from the lamp to illuminate the outlet end of the outlet tube 11 of the fillin'g nozzle, and to also illuminate the upper portion of the container or tank 36 at location adjacent the mouth or filling opening 37 thus enabling an attendant to readily see when a container or tank being filled (as by manipulation of the lever 20 to lift the valve 17 is full, and avoiding overflow of liquid.

It will be evident that the lamp is so arranged relatively to the outlet tube of the filling nozzle as to be insertable with said outlet tube directly into a tank or other container. When a liquid, such as gasoline, is being dispensed, the rays of light emanating from the lamp are reflected by the gasoline in a great many different directions, with the net result that during a flow of gasoline,

Y the illumination of the upper portion of a container or tank is greatly in excess of the illumination at times when the outlet tube of the filling nozzle is inserted in a container or tank as in Fig. 2 and there is no flow of gasoline. While the flow of gasoline at one side of a lamp (say when positioned at a side of the flow, either within or without the outlet tube 11) assists the illuminating effect,

the arrangement as disclosed, wherein broken up and sprayed particles of gasoline completely encircle the lamp situated centrally of the outlet tube, aflords the maximum illumination of the upper portion of a tank or other container, for the reason that the gasoline provides a maximum number of particles or surfaces against WhlCh the rays of light from the lamp can strike to be refiected in many diflerent directions in the upper portion of a tank or other container, as will be understood.

As will be apparent, the casing 26 and the lamp housing,3l, which are both desirably of opaque material, provide a shade for the lamp, and the rays thereof are directed into the upper portion of the container in close proximity to the outlet end of the outlet tube 11. which can be inserted into a tank or other container any preferred distance during a filling operation. Thus, the light from the lamp can be concentrated in a tank or other container at any desired location directly adjacent its mouth or filling opening.

In some instances it may be preferable tov provide an outlet tube for the filling nozzle which is of flexible nature. Such an outlet tube is represented generally at 11 in Fig. 3, and is constructed after the general fashion of flexible tubing now of commerce and requiring no especial description herein. The flexible tubing 11' may be fitted into the body portion or grip part 10 of the filling nozzle in any suitable liquid tight manner, as denoted generally at 14:.

A flexible tube 24 supporting a casing 26', and otherwise functioning as does the bent tube 24, is secured in the body portion 10" as at 25'. A spider 38, upon the casing 26' and engaging the internal wall of the flexible tubing 11, holds said casing 26 centrally of said flexible tubing. A lamp housing 31' suitably attached'to the casing 26 is for the same purpose as is the housing 31.

It will be evident that in use the filling nozzle of Figs. 3 and 4 will function in the same manner as the nozzle of Figs. 1 and 2, already described, with the exception that the outlet tube 11' can be flexed or bent relatively to the body portionof the filling nozzle, which access might not otherwise be readily had. Naturally, the spider 38 causes the easing 26 and the parts carried thereby to follow the movements of the flexible tubing 11', while the flexible tube 24 readily flexes or bends inresponse to the movements of the flexible tubing 11.
