Application October 27, 1948, Serial No. 56,761

lMy invention relates to means intended to provide a resilient protective covering for the hand operated valve structures of dispensing nozzles, particularly of gasolineor other pumps aslused in gasoline stations and in other places, and in which the nozzle is inserted into a restricted filler opening after the cap covering such opening has been removed.

In using vsuch dispensing nozzles the gasoline station attendant Avery frequently hits the edge of the filler opening and the adjacent fender in which the opening' is usually mounted, and as a result thereof the finish of the automobile soon' becomes marred about the gasoline filler opening by repeated blows from the metal trigger guards and nozzles of such gasoline dispensing means.

.An object of my invention is to provide a novel device and covering of resilient material for dispensing valves and which device is of unitary construction and may be readily applied or removed from standard dispensing nozzles, but which nevertheless is securely'retained in position on the dispensing nozzle.

Another object of my invention is to provide a novel cover for a gasoline dispensing nozzle and which cover is free of .any metal clips, springs or other fittings, butwhich is held on the dispensing guard by the configuration of the molded cover.

A still further object of my invention is to provide a novel cover for guards of gasoline dispensing pump nozzles, and which cover is retained on the guard without additional means.

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detail description, and the appended claim.

The accompanying drawing illustrates the invention in a form I at present deem preferable.

Figure 1 is a side elevation of a typical gasoline dispensing nozzle, having my novel protective covering applied thereto.

Fig. 2 is a, rear elevation looking in the direction of arrow 2, Fig. l, and with parts broken away to contract the view.

Fig. V3 is Vlongitudinal vertical section of my novel resilient guard cover as shown in Fig. 1, but on a larger scale, and detached from the dispensing nozzle.v

Fig. 4 is an enlarged cross section on line 4-4, Fig. 1.

Fig. 5 is an enlarged cross section on line 5 5, Fig. 3.

In the drawing the numeral II) indicates generally a guard for the trigger of a typical dispensing valve particularly used for dispensing 1 claim. (o1. 137-379) gasoline, and generally comprises a tubular spout S, spout connection SC, valve housing V in which flowcontrolling valve mechanism is contained and operated by depression of valve stem VS, an inlet connection I, and valve stem operating trigger T pivoted at Tp to a small bracket BR mounted on and projecting from spout connection SC. The structure so far described is that of a standard dispensing nozzle and except in combination with my invention forms no part thereof. It will be noted that heretofore when a gasoline station attendant carelessly pushed the spout S into an automobile gasoline tank opening (not shown) and which spout and guard I0 are not combined or provided with my invention, the guard I0 is often struck against the edge of the ller opening, and in certain types of automobiles where the openingof the gasoline tank is concealed under the fender or car body, the spout connection SC' or guard It will strike against the car finish and scar the same, thereby making anV unsightly appearance of the cars` nish adjacent the iilling opening for gasoline of such car. vThis is particularly annoying and obnoxious to new car owners, particularly of the more costly models, as well as to owners of other cars. Y

As shown in Fig. 2 the rear of the guard is bifurcated as at 99, the arms Ia, Ib of guard I@ being connected to an ear I2 depending from inlet connection I by a pin I4 passed through holes drilled through the upper ends of arms Illa, IIlb and ear I2. The body yIlle of the guard extends forwardly to the bracket BR.

My invention comprises providing a protective covering 50 for the nozzle or spout S and the trigger guard Ill of a usual gasoline dispensing outlet, and which covering is particularly disclosed in sectional views Figs. 3, 4 and 5; and generally comprises a gasoline and oil resistant flexible material that is combined with the associated with the spout S and trigger guard I to prevent the diiculties heretofore encountered by careless or negligent attendants dispensing gasoline or other fluids to receptacle openings around which are highly polished or glazed surfaces, that may be easily marred by impact therewith of a nection SC, and thereby arrests further upward movement of the stop portion I6 thereon.

Extending laterally from portion I9 of the protective covering and preferably integrally connected thereto a trough or channel-shaped section 22 is provided. The end of the channelshaped section 22 adjacent the bumper portion I6 is shaped to fit over the lower face and edges of bracket BR', while the opposite end 49 of the section 22 ts closely around the knuckle at the lower end of the vertical bifurcated end formed by the arms lila and of the guard I9 and is continued therearound and upward sufciently to overlie the opening between the arms lila, IJb. At the point where the 'guard end 49 overlies the space between arms 19a, i917 the inner surface of the guard channel 22 is provided with an inwardly projecting stud 24, preferably molded integrally with the unitary guard protective covering and which is received in and engages in space 99. The length of the cover l!I is preferably slightly less than that of the guard I9 soV that when the protective covering therefor is stretched and mountedV inposition the elasticity of the guard cover 50 will retain the same 2 tightly inposition on the guard', and the stud 24 will be retained in groove or space 99 to prevent the end 49 of protective guard from becoming disengaged from the `E ifurcatedr guard I9.

The underside IUc of the trigger guard I0 is usually provided with a rib 35, and the channel 36 cf my protective guard 22 is provided with a groove 3'! to receive the rib 35 and thereby, together with the

upstanding arms

38 and 39 of the protective guardv 22 and the tension exerted by the elasticity and pull of the end 49 against the end 19a and of the triggerY guard, will serve to maintain my protectiver guard on the nozzle without extraneous means, so that my trigger guard may be sold as an independent unit for association and combination with standard gasoline dispensing nozzles now in use.

It wil-l be evident that in use, since an attendant commonly slides the nozzle through the gas tank opening with the nozzlev against the side of the opening, the bumper I9 will engage against the edge of the filler opening and stop further inward movement of the spout and thus prevent the trigger guard from hitting against the edge of the opening or the adjacent fender, and if the attendant in manipulating the nozzle does hit the car body with the trigger guard adjacent the gas iilling opening, the resilience of the cover guard 50 will prevent any damage being done to the car nish adjacent such opening.

My invention particularly relates to the combination of my novel protective guard with a gasoline dispensing nozzle as above described and dened in the appended claim.

The combination with a dispensing spout for fluids. having a trigger guard associated therewith, and' which trigger guard is bifurcated at the rear thereof; a unitary member having one end provided with an orifice to receive the dispensing spout thereof; a channel member eX- tending from said spout receiving membervand adapted to embrace the lower side of said trigger guard; said channel member being provided with an upturned end to embrace thev rearv of said trigger guard; and said upturned' end being pro'- vided with a protuberance to be received between the bifurcated ends of said trigger guard; said channel member being held on said trigger guard by resiliency of said channel vmember along said trigger guard', and the engagement of said upturned end with the rear thereof.
