This invention relates to illuminating filling nozzles.
One of the objects of the invention is to devise a fitting for attachment to a valve controlled nozzle for dispensing gasoline in which is mounted a source of illumination so that the interior of the gasoline tanks being filled may be seen by the operator.
Another feature of the present invention is to devise a thoroughly insulated mounting in the device so as to eliminate any possibility of from short circuits or sparksin the device.
Further objects of the invention are to provide a device of the character referred to that strong, compact and durable, thoroughly reliable for its intended purpose, design-ed particularly for attachment to outlet nozzles, that is easily assembled and disassembled from the nozzle, and cornparatively inexpensive to manufacture.
With the foregoing and other objects in view the invention consists of a novel construction, combination and arrangement of parts as will be hereinafter more specifically described and illustrated in the accompanying drawings wherein is disclosed an embodiment of the invention, but it is to be understood that changes, variations, and modifications may be resorted to without departing from the spirit of the claims hereunto appended.
In the drawings wherein like reference characters denote corresponding parts throughout the several views:
Figure 1 is a side elevation of a valve controlled filling nozzle illustrating an adaptation therewith of a device in accordance with the present invention.
Figure 2 is an enlarged fragmentary sectional view of the attachment.
Figure 3 is a radial section through one branch of the attachment taken substantially on line 3-3 of Figure l and looking in the direction of the arrows.
Figure 4 is a side elevation of the light support removed from the one branch.
Figure 5 is a perspective view of the reflecting sleeve.
Referring to the drawings in detail, 5 indicates the outlet conductor of a filling nozzle A of the conventional character used in dispensing gasoline. The filling nozzle includes a valve El operating in response to the stem 9 which stem is controlled by the lever ifl rockably on a pin it and this pin is mounted in a hand guard l2 carried by the nozzle A. The rear end of the nozzle A is customarily connected with a flexible pipe l3 which conveys the gasoline being dispensed from V the pump. The nozzle A is customarily inserted in the neck on the gasoline storage tank of the automobile and by pressing the lever- It the gasoline is dispensed therethrough.
The fitting of the present invention is indicated generally at B and this fitting is substantially V-shaped and includes the stem I4 and the two branches l5 and I6. The branch 16 is on the same axis as the stem I l so that the source of illumination, to be presently described, will refiect light out through the open end of the stem at through which the gasoline passes. The rear end of the stem merges with the branch and the inner end of this branch I5 is formed with an interiorly threaded flange ll that is detachably secured to the free end of the noz- A. The branch l6 merges with stem 84 slightly above the juncture of the branch passage I511 and the stem passage l la, so that the source of illumination may be mounted and confined solely in the branch l8 so as not to interfere with the passage of the gasoline from passage l5a, and out through stem passage Ma. The gasoline from the nozzle A passes through branch I5 into the stern it and out through the open end of the stem. The branch 65 and the branch 16 are disposed at an angle with respect to each other.
Where the branch l5 joins or merges with the stem 54 there is an outset shoulder IS on the branch 16 which forms a ledge on the interior of branch IS on which rests the rubber strip IS. The interior of branch [6 forms the light chamber Ita above the shoulder. There is a lens 20 supported on the rubber strip l9 which lens is plane on the outer face and convex on the inner face. In the light chamber mounted co-axial therewith is a light reflecting sleeve 2|, the inner end of which rests upon the margin of the plane face of the lens 20.
Resting on the other end of the sleeve 2| is a fibre insulating disk 22 having a marginal flange 23 conformably fitting the end of the refiector. In the center of the disk 22 is supported a light socket 224 in which is detachably connected the light bulb 25. So as to insure perfect insulation there is mounted a knob 2r: of sealing Wax about the outer end of the plug and through the sealing wax knob 26 extends the electrical conductor wires 21, 28. To hold the electric light supporting disk 22 there is a bowl shaped cap 29 threadably connected with the end 01' the branch it as at 353. In the crown of the cap 29 there is mounted in an opening therein, the
screw bushing 3| formed with a central opening through which the electrical conductor wires extend. The inner face of the disk support 22 reflects the light and the sleeve 2| also reflects light directly down through the stem l4 so that light will be thrown into the gasoline tank for the convenience of the operator.
We propose to use a low voltage in the device and for this purpose we use an ordinary flashlight bulb 25. To insure the utmost safety we install in the electrical conductor wires 21, 28 a safety fuse that will disrupt the current in event of any short circuit. The electrical conductor wires 21, 28 lead to a transformer (not shown) which transformer may be connected with the lighting circuit of a filling station (not shown). By coupling the light bulb 25 with a low voltage circuit, utmost safety is insured so that no short circuit or sparks are likely to cause fire when dispensing the gasoline.
Having thus described the invention, what is claimed as new is:
1. The combination with a valve controlled filling nozzle of a Y-shaped pipe fitting including a stem and two branches, one of said branches being disposed on the same axis as the stem, the end of the other branch being adapted for attaching to the filling nozzle, and an electric light mounted and confined solely in the other branch for directing light into the stem.
2. A valve controlled filling nozzle including a conductor having the discharge end equipped for detachable connection to another conductor; the combination with the aforesaid elements of a Y-shaped tubular fitting including a stem and two branches, an outset shoulder formed about the juncture of one branch with the stem and on the interior thereof, the assembly of elements constituting a source of illumination receiving their support at one end from said shoulder, a cap detachably connected with the free end of said one branch cooperating with the aforesaid assembly of elements to retain said assembly confined solely within said branch in supported relation on said shoulder, and means on the free end of the other branch for detachable connection to the nozzle conductor.
3. In combination, a filling nozzle for inflammable fluids equipped with an attaching means on the discharge end, a substantially Y- shaped fitting including hollow branches and a hollow stem, one branch provided with a fitting on its free end adapted for detachable connection with the aforesaid attaching means, said one branch and stem forming an outlet passage for the inflammable fluid, and a source of illumination mounted and sealed within the other branch above the juncture of the stem and said one branch in a manner to reflect light through the free end of the stem.
4. In combination with a dispensing nozzle for inflammable fluids of a fitting detachably connected at one end with the nozzle and formed with a passage through which inflammable liquids are discharged from the nozzle, said fitting having a hollow branch joined thereto and communicating with the passage in a direction diverging therefrom, and a source of illumination mounted in and confined in the branch above the juncture in a manner to reflect light through the free end of the fitting.
5. In combination with a dispensing nozzle for inflammable fluids having a hollow passage for discharging fluid of a hollow branch joined with the nozzle and communicating with the discharge passage, said branch disposed in a direction diverging from the path of flow through the nozzle, and a source of illumination mounted and confined in the branch above the juncture in a manner to reflect light through the free end of the nozzle.
