3 Claims. 1

My invention relates to a new and useful improvement in a filling spout adapted for use on tanks. such as gasoline tanks to afford a means for depositing the liquid in the tank.

An object of the invention is the provision in a filling spout having a pair of telescoping tubes with the inner tube provided with a closure for closing the outer end and all so constructed and arranged that when the inner tube is thrust inwardly its full length, the closure of its outer end will lie flush with and in general appearance form a continuation of the surface of a fender or the like through which the filling spout is adapted to proceed.

Another object of the invention is the provision in a filling spout having an inner tube with a closed outer end provided with a gripping portion which is normally invisible.

Another object of the invention is the provision in a filling spout having a slidable inner tube with a closed outer end and provided on the outer surface of the closed end with a gripping portion corresponding to the surface of the body through which the inn r spout is adapted to project.

Another object of the invention is the provision in a filling spout having a pair of telescoping tubes of a novel construction relating particularly to the sealing.

Another object of the invention is the provision in a filling spout having a tube of a construction so arranged that the sealing gasket may be sealed and quickly mounted therein.

Other objects will appear hereinafter.

It is recognized that various modifications and changes may be made in the detail of structure illustrated and it is intended that such variations may be encompassed within the scope of the claims which form a part hereof.

Forming a part of this specification are drawings in which Fig. 1 is a central section or view of the invention with par-ts broken away and some shown in side elevation.

Fig. 2 is a view similar to Fig. 1 with the inner tube in the extracted position.

Fig. 3 is a fragmentary sectional view showing a slight modification.

Fig. 4 is a fragmentary sectional view showing a further modification.

In the drawing, I have illustrated the invention mounted on a tubular neck 9 which extends upwardly from a tank or container H]. An outer tube ll formed preferably from sheet metal is connected by the flexible sleeve l2 to the neck 9.

In the drawing, I have illustrated the invention used adjacent automobile fender l3 having an opening it formed therein and punched inwardly around the opening to provide the flange H5. The outer tube H i pressed outwardly at its upper end to provide the flange it which rests upon the upper face of the flange l5 and which may be suitably secured thereto by welding, soldering, riveting, or in any other suitable anher. The fender 5-3 thus serves as a supporting member for the outer tube l I and when the outer tube 5 l is mounted on a fender as indicated, the fender itself serves as a covering or protective shield for the tube.

Formed in the inner face of the tube H, adjacent its upper end, is an annular groove I corresponding to a similar annular groove !8 formed on the inner surface of tube l adjacent the lower end thereof. Formed in the inner face of the tube I l adjacent its upper end is a groove l9, and seated in this groove It is a ring 2b of sealing material such as rubber, felt, leather, or the like. Slidably mounted in the tube l I is an inner tube 2! having a bead 22 formed on its inner end and provided with a plurality of circumferentially spaced apart axially directed slots 23.

Formed in the inner tube El adjacent the outer end thereof is a lateral opening 24 which is exposed when the inner tube is drawn outwardly as shown in Fig. 2 to receive the nozzle of a filling hose.

The outer end of the tube 2! is turned outwardly to provide the radial flange 25 which is bent angularly as at 26 and thence radially as at 2? to provide a structure for gripping th ring 28 of sealing material formed from rubber or other suitable material. When the tube 21 is thrust fully inwardly of the tube H the sealing ring 2!; will engage the flange iii and the bead will have snapped into the groove 18. When the tube ii is drawn outwardly as shown in Fig. 2 the bead 22 will have snapped into the groove ll so that there is thus provided a yieldable or resilient means for resisting the movement of the tube 28 from open to closed position and from closed to open position. In the slidable movement of the tube 2% the ring 29 of sealing material will bear tightly against the periphery of the tube 21 so as to prevent leakage around the tube 2i.

A plate 29 serves as a closure for the outer end of tube 2! and rests upon and is suitably secured to the outer face of the flange 25. As clearly shown in Fig. 1 when the tube 24 is moved to fully closed position the outer face of the closure 29 lies flush and forms a continuation of the outer face of the fender l3.

Formed in the closure 29 is a central opening 30 opening into a housing 3| Positioned in this housing 3! is a spring 32 pressing the disc 33 into position for closing the opening 30. When the tubes are in the position shown in Fig. 1 and it is desired to pull the inner tube outwardly, the disc 33 is thrust inwardly by a persons finger against the compression of the spring 3! allowing the finger to grip the closure 23 and draw the tube outwardly.

In Fig. 3 I have shown a slight modification,

A tube 2|A corresponds to the tube 2!, the flange 25A corresponds to the flange 25, and the ring 28A corresponds to the ring .28. The plate 29A corresponds to the closure 29. This plate 29A is provided with an opening. 30A corresponds to the opening 30. A disc 33A corresponds to the disc 33 and this disc 33A is pressed by the spring legs 34 into closing position, these spring legs being mounted on the crossbar 35.

In Fig. i, I have illustrated the invention in which the tube 25B corresponds to the tube 2i of Fig. 1. A closure 29B is mounted on the tube ZlB. Mounted on and extending across the closure 23B is a strip d corresponding in contour to a decorative strip of moulding shown in dotted lines. As shown the strip .0 has a raised portion to provide a finger grip. This illustration is presented to indicate the application of the invention to a structure which has a moulding strip mounted thereon.

What we claim as new is:

1. A filling spout of the class described, an outer tube; a supporting body for said tube having an opening formed therein, said tube extending out- Wardly from one side of said body and said opening; a flange on said body off-set inwardly therefrom around said opening and projecting radially of said outer tube to provide an inwardly off-set recess; an outwardly projecting flange on the end of said outer tube engaging with and secured to the flange on said body; an inner tube slidably mounted in said outer tube, one end thereof projecting beyond the end of said outer tube and extendable outwardly from the opposite side of said body; a securing structure on the outer end of said inner tube; a ring of sealing material carried by said securing member and engaging, upon inward sliding of said inner tube into said outer tube, with the flange of said outer tube for effecting a sealing engagement; a closure on the outer end of said inner tube, free from outward projections and extending outwardly beyond the periphery of said inner tube and lying with its outer surface flush with the surface of said surrounding body when forming a continua tion of the contour thereof upon inward sliding of said inner tube its maximum distance and forming a closure for said recess.

2. In a filling spout of the class described, a supporting body having an opening formed therein; an outer tube secured at one end to said body in registration with said opening and projecting outwardly from one side of said body; an inner tube slidably mounted in said outer tube, one end thereof being adapted for projecting beyond the secured end of said outer tube; a closure for the projecting end of said inner tube, free from outward projections on its outer face, and adapted for lying with its outer face flush with the surface of said supporting body and forming a continuation of the contour thereof upon inward sliding of said inner tube its maximum distance, there being an opening in said closure; and spring pressed meansfor normally closing said opening.

3. In a filling spout of the class described, a supporting body having an opening formed therein, said body being inwardly off-set around said opening to provide a recess surrounding said opening inwardly off-set from the outer face thereof and a flange portion extending outwardly from said opening; an outer tube secured at one end to said body in registration with said opening and projecting outwardly from one side thereof; a flange on said end of said outer tube engaging the flange in said inwardly off-set portion; an inner tube slidably mounted in said outer tube, one end thereof being adapted for projecting beyond the secured end of said outer tube; a closure for the projecting end of said inner tube, free from outward projections on its outer face, and projecting beyond the periphery of said outer tube and of a diameter substantially the same as the diameter of said recess and adapted for lying with its outer face flush with the surface of said supporting body and forming a continuation of the contour thereof upon inward sliding of said inner tube its maximum distance and forming a closure for said recess.
