Patented Aug, 9, 1932 UNlTI-:o fSTATES PATENT! oFFlcE JONATHAN NEWTON. WHITE, OF NEW YORK. N. lY., ASSIGNOB TO UNITED METAL HOSE CO. INC., OF NEW YORK, N. Y., A. CORPORATION OF NEW YORK NOZZLE Application led August 27, 1928. Serial No. 302,155.

This invention relates to nozzles and metal lined hose -of the type used to dispense inflammable liquids, and most' particularly gasoline from fuel stations and filling devices to automobile tanks.

An object of this invention lies in the provision of a simple strong structure which will positively engage the hose'end and form a nozzle therefor without intermediary fittin s or parts and will when engaged withI Suc hose form, for all practical purposes, a unitary part thereof and remove any likelihood of accidental detachment in service so that this nozzle may lserve as a.- hanger forl character;-various makeshifts, grounding chains, wire clips and the like, have been tried but have failed in that seldom if ever were all of the metal parts always in direct electrical contact so that no potential difference could exist'therebetween. It is the purpose of the herein disclosed invention to automatically provide direct contact between, and grounding of, the metallic hose and nozzle and the tank or other container into which discharge is made without other media than the parts themselves and without other operation than that involved by the usual use of the said partsfor Huid discharge. y

It is also a function of the herein disclosed invention to provide means for protecting* permitting use of rubber" and like materials where such are best suited 4and for the complete isolation of such materials from the fluids handled.

Reference to the following description, the attached drawing, and the appended claims will serve to further disclose the above, and certain other improvements and objects accomplished by this invention.

Figure 1 is a side elevation of an embodiment of my invention, a portion only of the hose being shown and the main part of the structure being broken away substantially on its center line to facilitate description.

Figure 2 shows a modification of the embodiment of Fig. 1 and is taken in substantially the same fashion as that ligure.

Figure 3- serves to illustrate a hose embodying my invention in actual use.

A preferred formof metallic hose 9 utilized a for the purposes described consists of a Woven fabric outer cover 10, a rubber layer 12, and a metal lining 14. This hose, in one of its most common uses, Aextends from the gasoline dispensing pump to-the automobile tank to be filled and into whose filling opening 16 the gasoline is to be discharged. It will be understood that the openings 16 in vdifferent automobiles are locatedin various positions and vary in size and shape so thaty I an elongated discharge portion 21 of the hose nozzle 20 is customarily p rovided for convenience in inserting the nozzle in the tank opening and that a holding lug 22 serves to assist in holding the nozzle in position in the tank opening. The pump end of the hose 9 is preferably united to the gasoline pump 11 in such fashion that metallic lining 14 forms a continuous extension o'f the metal parts thereof (which are thoroughly grounded through tank llt) and it is one of the important featuresv of this invention that the novel form of nozzle now disclosed permits a further metallic extension of the said completel grounded parts and for the completion'o an all metal conduit and connection 'to the tank opening 16 and the metal parts of the car, preventing contamination of the gasoline, destruction of the rubber and fabric portions of the hose, and anyelectrical potential dierence capable of/p'roducing a spark between the parts. -f The nozzle 2o has a discharg ltending therethrough and surrunded at'the bore 23 ex-g n hose end by a recess 24 slightly larger than the hose 9 whose end extends into this recess and abuts against a suitable shoulder or gasket 26 at the inner end of the recess. 'llhe body of nozzle is enlarged to accomodate recess 24.- and upon this enlarged portion ll prefer to provide a thread or equivalent engement device 28 and a convenient h olding ange 29 which may be six or eight sided to accomodate a wrench, if desired. 'lhread 28 serves for the engagement of sleeve which is internally threaded, as indicated, so that it may be drawn and tightened upon the nozzle body, a wrench application portion 32, somewhat similar to dange 29, providing for ositive engagement between the parts. leeve 30 is internally recessed at 34: to accommodate a helical compression member 40 (see also Fig. 3) which engages the outer surface of the hose 9 and which (when the sleeve 30 is tightened on the body 20) is compressed thereon and lsecurely clamps the hose while at the same time permitting the movement of sleeve 30, as it draws upon the body 20, to ltorce the end of hose 9 tightly against shoulder or gasket 26 and to tightly seal the end of the hose to the nozzle body.

The positive seal between the metallic lining 14 of the hose 9 and the body of nozzle 20 is further aided, while an electrical contact is automaticall and securely edected, by a projectionlor ange upon body 20 entering and engaging the metal lining lt and uniting it with the metal of body 20 so that the two are mechanically and electrically a single unit when so joined. .This construction will be seen to completely eliminate intermediary ttings and then unavoidable acked joints, thus substantially reducing the iability to leakage or failure while reducing the cost of construction and increasing the strength and usefulness of the structure as a whole. v

It will be understood that utilization of the means above set forth so applies the nozzle to the hose that accidental separation therebetween is almost an impossibility, compreion member 40 gripping the hose lmore ti htly as pull between the ytwo increases. T us itis entirely practical to' place a hanger 52 upon the exterior of nozzle 20 and for such hanger to replaceany form of hanger former needed on the hose itself thus effecting an a ded function and a substantial improvement over direct hanger contact with the outer hose cover l() and its consequent early destruction. Hanger 52 is here shown as 1n th e form of a ange adapted to be placed within the forks of a suitable holder ll-t secured'to the gasoline ump (see dotted lines Eig. 3 for the hose in ung up position) or like convenient support, but it will be understood that. a hook or like hanger may be equally well incorporated in the nozzle struc- .ture when desired.

nemica Figure 2 serves to illustrate that embodiment of my invention wherein the rlgid elongated portion 21 of the nozzle is replaced by a suitable ilexible portion 21a which 1s also positively mechanically and electrlcally joied with the nozzle body at and .whlch may extend to such length and direction as desired and thereby facilitating nozzle application in many instances.

The exible portion 21a will be seen to 1n no way prevent useful applying of all of the means hereinbefore described and it will be noted that the uniting and protective functions are fully performed as in the preceding embodiment like numerals having been applied to like parts in the drawing.

While l have described my device as particularlysuited `for the dispensing of gasoline and like inlammableiiuids it will be manifest that many ot /r uses are possible and while certain en odiments have been set forth as preferabl it will be understood that many modicati ns in the whole and lin the parts thereof are well within the scope of my invention and the spirit of the appended claims.
