Description

?etented New. 7, 1933 units reruns FFiQE The object oi the invention is to provide a nozzle for use in connection with gasoline dis pensing pumps, so constructed as to incorporate an illuminating means to cast a. beam of light directly ahead of the discharge mouth thus permitting clear vision of the interior of the can or tank being charged so that its condition with indicated which is of simple form and therefore susceptible of cheap manufacture.

With this object in view, the invention consists in a construction and combination of parts or which a preferred embodiment is illustrated in the accompanying drawing but to which embodi-= merit the invention is not to be restricted. Continued use in practice may dictate certain changes or alterations and the right is claimed to make any which fell within the scope of the eunened claims.

In the drawing:

Figure i is a central longitudinal vertical sectional view of a Tnozzle constructed in accordance with the invention. i

Figure 2 is an elevetionol view of the illuminsting means detached.

Figure 3 is an end elevetional view of the invention.

Figure s is an elevationel new, collectively, oi the circuit closer, piston and actuating means for the some. i

The illuminating device constituting the invention is housed in a tube 10 designed to be removably mounted in the nozzle 11 which is of the conventional form but modified over the usual practice by being formed with a branch 12 extending in the direction of the discharge mouth, this branch 12 being interiorly threaded to serve as a means for supporting the tubular housing lb. The means for supporting the tubular housing consists of e. plug mem ber 1d threaded hito the tube ru es indicated at 15, this plug member being shouldered as indicated at 16 to provide an abutment stop for the end or the tube. met-lorly, the plug member is threaded, as indicated at 1'7, to be removably engaged in the internally threaded branch 12.

The heed 18 of the plug is hexagonal, square, or some other polygonal form to permit the application of a wrench, so that the plug member may be readily engaged with or removed from its sent in the nozzle. l

The tube 10 extends to the forward or discharge end of the nozzle 11 and seated in this forward end is a bushing 19, the latter being formed with a web portion 20 bored and tapped for the reception of a. lamp 21, the center contact of which is engaged with the center contact of a cell 22 which is housed in the tube 10 in series with a cell 23 against the rear end of which is seated an insulating disk 24; formed with a tubuler necir 25 in surrounding relation to which is disposed a compression spring 26, the latter bear= ing one end on the disk and the other end on the head 2? of a circuit closer whose stem 28 is slida bly mounted in the tubular extension, so that when the spring 26 is compressed, the end of the stem may beer on the heel end of the cell 23. Under such conditions, u circuit will be establiehed on the lump, since the head of the circuit 8d closer is in contact with the wall of the tube, whereas the sleeve contact of the lamp 21 is also in electrical contact with the tube by reason of being mounted in the web portion of the bushing 19. Current will thus flow from the battery of 85 cells through the center contact of the lamp, through the filament to the sleeve contact, thence to the wall of the tube and thence to the heed 2'? and stem 28 of the circuit closer beck to the battery.

To positively preclude any danger of ignition oi the gasoline being discharged through the nozzle by any sparks resulting from the mowing and breaking of the circuit on the lamp. the lat= ter, the circuit closer and the battery are ex- 95 eluded from the entrance of moisture. The tube 10 at the forward end houses a lens 29 which is seated against the forward end 01 the bushing 19 and against this lens is seated a gasket 30,

preferably a ring of some ductile material of the loo character of zinc or copper. Against this gasket is seated a ring nut 31 threaded in the end of the tube 10 and provided at its forward edge with diametrically disposed slots 32 in which may be seated at spanner wrench by means of which the nut may be removed or replaced and under all circumstances is seated firmly against the gasket so. I

The moisture excluding means employed in connection with the circuit closer consists of a no piston 33 formed with a peripheral groove in which is disposed a packing 34 bearing frictionally against the interior wall of the tube 10. The actuating plunger 35 which is slidably mounted in the plug 14 has a foot portion 36 bearing on the piston 33 and a pin 3'! bearing against the inner end of the plug when the plunger is extended. A button 38 is threaded on the outer end of the plunger 35 to serve as a means to be engaged by the thumb of the user to actuate the plunger.

The plug 14 is counterbored, as indicated at 39, to provide a clearance space for the movement of the button or head 38.

The spring 26 functions to yieldingly hold the circuit closer out of contact with the battery and the latter is engaged therewith by manual actuation of the plunger to force the piston and with it the circuit closer axially along the tube 10 until the circuit closer is engaged with the battery. The release of pressure from the plunger permits the spring to function and eifect circuit opening movement.

The invention having been described, what is claimed as new and useful is:

1. A dispensing nozzle having a tubular housing arranged longitudinally thereof and removably supported therein, a lamp enclosed in the tubular housing, a battery for energizing the lamp, a circuit closer housed in the tube adjacent the energizing means, moisture-proof means closing the forward end of the tube, exteriorly disposed actuating means for the circuit closer, and a moisture-proof member operatively connecting the circuit closer and the actuating means therefor and comprising a piston provided with peripheral packing bearing against the wall of the tube and interposed between the actuating means and the circuit closer.

2. A dispensing nozzle, a tubular housing arranged interiorly thereto and longitudinally thereof, a plug threaded into the rear end of the tube and having a shoulder abutting the end thereof, the plug being threaded into the nozzle to support the tube therein, a lamp mounted in the forward end of the tube, an energizing battery for the lamp, and a circuit closer mounted in the tube between the battery and said plug and provided with an actuating means extending through the plug.

3. A dispensing nozzle comprising a tubular housing arranged interior to the nozzle and longitudinally thereof, a lamp mounted in the forward end of the housing, a lens disposed in the forward end of the tube ahead of the lamp, a battery mounted in the tube for energizing the lamp, an insulating disk disposed in the tube against the rear end of the battery and formed with a tubular extension and an opening therethrough in axial coincidence with the bore of said extension, a circuit closer having a stem slidably mounted in said extension and formed 100 with ahead, a spring in surrounding relation to said extension and compressed between said head and said washer, a piston provided with peripheral packing bearing against the inner wall of the tube, and a plunger slidably mount- 5 ed in the tube and formed with a foot, the piston being disposed between the head of said circuit closer and the foot of said plunger and in contact with both when the plunger is pressed to actuate the circuit closer.
