2 Claims.

This invention relates to hose nozzles; and it has more particular reference to nozzles for the drain hoses of vehicles such as are ordinarily used in the delivery of gasoline, oils and other 5 liquid commodities.

The filling openings of underground gasoline storage tanks of road service stations vary considerably in diameter so that tips of different sizes are ordinarily supplied for use with the nozzles on the hoses of the delivery vehicles. heretofore, reducing nipples were relied upon as a means for effecting interchange of the nozzle tips; and accordingly the operation of interchanging the nipples was not only tedious in its accomplishment, but entailed the use of wrenches or other special tools. In order to avoid this effort and trouble, the drivers of the delivery vehicleswould invariably keep the smallest nozzle nipple .as a permanent fixture on the hose since it could be used universally, and this choice was made notwithstanding great loss in time in charging tanks whereof the filling openingswere capable of taking larger or even full size nozzles.

Considered from the broadest aspect, my invention is directed toward overcoming the above recited drawbacks, that is to say: it has for its primary object the provision of a simple and inexpensive nozzle for the drain hoses of gasoline delivery vehicles and the like, with tips which can be interchanged with the utmost facility and quickness, and without requiring the aid of any tools whatever.

An advantage of my novel hose nozzle is that it positively ensures quick attachment and detachment of the nozzle tips by partial rotation of one of the parts only.

Other objects and attendant advantages of this invention will be manifest from the following detailed description of the accompanying drawing wherein Fig. I is a fragmentary view partly in side elevation and partly in section showing my improved hose nozzle in one of theforms in which it may be embodied.

Fig. II shows a nozzle tip. having a tubular discharge prolongation of a smaller diameter, capable of being interchanged with the nozzle tip shown in association with the nozzle in Fig. I;

Fig. III is a staggered horizontal section taken as indicated by the arrows III-III in Fig. I.

Fig. IV is a fragmentary sectional view of a portion of Fig. I with the parts difierently positioned; and,

Fig. V is a view similar to Fig. III with the parts differently positioned.

Referring first to the embodiment of my in- 933, Serial No. 678,619 (or. zss- -ss) vention shown in Figs. I-V of these illustrations, the numeral ll designates a flexible hose such as is used on vehicles employed-in the delivery of gasoline, oils and other liquid commodities, the same being fitted at its end wit fathreaded nipple l2. My improved hose no 'zzl'e' which is comprehensively indicated at I3 comprises a body member in the form of an elbow H which, as shown in Fig. I, screws onto the threaded nipple l2 with interposition of a compressible ring washer 15 to prevent leakage-around the juncture. The mouth end of the elbow I3 is enlarged as at l6 and formed internally wi th a circumferential groove IT for lodgment of the peripheral flange of an annular gasket I8. In practice, this gasket [8 is made from a soft resilient material which is resistive' to erosion by the liquid commodities being carried. The'"e'n1arged mouth end [B of the body member I4 is circumferentially recessed at l9; and a flanged annulus 20 screwed onto said mouth end forms, in conjunction with the recess IS, a perimetric groove around said mouth. Rotatably retained within this perimetric groove is a wedge ring 2|, which, as shown in Fig. III, is formed internally'thereof with a circumferential series of recesses 22 having cam slopes or inclines 23. The wall of the mouth end IQ of the elbow I4 is moreover formed 7 with radial openings 24 corresponding in number to the recesses 22 in the wedge ring 2|, each such opening lodging a ball 25. As shown in Fig. III, the openings 24 are tapered to retain the balls 25 while limiting inward radial movement thereof.

For interchangeable use with the body member H of the nozzle I provide a number of-tips whereof there are two shown for the purposes of exemplification in the present instance, one designated 21 in Fig. I and another designated 21a in Fig. II, the nozzle 21a differing from the nozzle 21 in that it has a tubular prolongation 28a which is smaller in diameter than the tubular prolongation 28 of said nozzle 21, and also in a detail which will be later described. Referring again to Fig. I it will be observed that the nozzle tip 21 has a head 29 which is counterbored as at 30 to receive the prolongation 28, the latter being in practice cut from tubing of alloy bronze or other suitable non-corrosive metal capable of withstanding rough usage. After assembling of the parts of the tip 21, they are permanently secured together by soldering or welding preferably at 3| immediately beneath the head 29, which latter is provided with a rounded circumferential groove 33. The diameter of the bore 84 of the'tubular prolongation 2| 0! the nozzle tip 21, it will be'observed, corresponds exactly to the diameter of the passage 85 in the elbow It, so that the maximum discharge how is bad with said tip.

The head 28a 0! the substitutable noule tip 11a has an external diameter corresponding to that of the tip 21 so as to fit, like the latter, into the mouth It of the nozzle elbow i4, and it is similarly provided with a circumferential groove 33a; The head Ila or the nozzle tip 21 is however rounded interiorly at I. for smooth mergence o! the bore Ila oi .the prolongation Ila with the passage 3! oi the elbow I4 and minimization of the impedance to fluid fiow throughthenomle. Y

In attachingthe nozzle tipll, for example, -the wedge ring is turned to the position shown in my, to register its'recesses. 12, with the openings 24 in the wall of the elbow mouth it andtopermittheballsfltoretire into said recesses. Thereupon, the head end 2l oi the tip 21 is inserted into' the elbow mouth It as shown in Fig. IV until'its endrahuts the gasket It, the allocation of the circumferential groove- 33 of said head being such that in this position 0! the tip 2I, the groove are slightly below the level of the radial openings 24 in the wall of the elbow enlarged mouth end I.

In

order to limit the extent or rotation of the" wedge ring II the latter is provided, as shown in 'l'l'gs. I, III, lv and V with a pair 01' spaced upward lugs 31, 38 for cooperation with a lateralstud nozzle ll.

From the foregoing it will be seen that the interchangeable nozzle tips are quickly attachable and detachable through a partial rotation of one part relative to the other.

Having thus described my invention, I claim:
