2Claims. l *The present inventiony kdeals with a dispensing 'hose that is commonly associated with a gasoline pump for thepurpose of'c'onveying gasoline from the-pump to the gasoline tank to be filled, such asthatof an automobile.

`vAt thepresent time, operators' 'of service stations and other places engaged in the commercial dispensing of gasoline, often eXperience'inconvenience in lpositioning the automobile, having the tank'to' be filled, with 'respect to the pump. 'This difficulty may be' attributed largely .to the fact that the hoses now'associated with' the 'pumps are-not suiiiciently long to aord a wide latitude in'the position of the car with' respect to the pump.

The obvious answer to this unsatisfactory condition is to make the hose longer. However, should the now available hose beso lengthe-ned, they become unwieldy and their storage'when not4 in usepresents a seriousproblem. Under present day conditions, the length 'of` a'" hose is limited' to one tur-nv or fold whichmay be hung onthe pump. That is, it is notnow practical to have a hose any longer than one which may eX- tend downwardly'vfrom itspoint of connection tor a` pointadjacent to' thev ground and then upwardly toA a rack for the nozzle.

With the foregoingconditionsin mind, the presentinvention hasV in view, as'r its foremost objectivathe provision of a hose intended for gaso- -1 line" dispensing purposes which is so designed and constructed Aso as to include self-'coiling properties. When such a hose is used, it normally returns to a coiled position without entailing any ceiling operation. onJthe part of the operator. It may bel pulled from its coiled position against the inuence of a spring means'which retains it therein, and therefore. does not require any more Vattenti'onirom the. operator than the now known hose.

In attaining the abovevnoted objective, a yieldable element is associated with a certain section of the hose length in such a manner as to cause that section to assume a coiled Position when all external forces are removed. The presence of this coiled section which may embrace a plurality of. coils. or turns permits the use of anydesired length. of hose with any conventional present day gasoline pump under the same conditions-of attachment and' bracketing'at the nozzleend.

.A further objective ofthe invention lies in the provision of a gasoline dispensing hose of the type above indicated, together With a spring that is coiled about a predetermined intermediate section thereof. This spring causes that section 2 to assume a coiled condition When any exterior distorting forces are removed.

Another object of the invention is the provision of a gasoline ydispensing hose of the character aforesaid, in which the usual composite rubber wall structure of the hose is supplemented' by a strip of rubber composition or comparable'material over a predetermined length and in which strip is embedded a leaf spring which normally maintains that portion of the hose in a coiled condition.

' Yet another object of the invention is the provision of a modification in which the hose proper is provided with a casing extending partially therearound and over a predetermined intermediate length. This casing is preferably of a rubber composition comparable to that from which the hose is made and each free edge of the casing has embedded therein, a spring strip. These springstrips normally retain that portion of the hose `over which 'they extend in a coiled condition.

` Various other and more detailed 'objects and advantages of the invention such as arise in connection with carrying out the above notedideas in a' practical embodiment will in part become apparent and in part be hereinafter stated as theV description of the invention proceeds.

The invention therefore comprises a gasoline dispensing hose! having an intermediate length provided with spring'means for normally retaining Vsaid length.. in a coiled condition.

For a' full andmore complete understanding of the invention, reference may be hadv to the following description and accompanying drawings wherein:

Figure 1 is a perspective View of a gasoline pump anda portion of an automobile havingits gas tank connected tothe pump by a dispensing hose designed iny accordance with the precepts of this invention;

Figure 2 is a View in end elevation of the pump with the'hose coiled and stored in its non-used position. This view vdevelops Vcertainbroken line positions ofA the hose illustrating themanner in which it mayloe-extended;

Figure 3 is a view in sideelevation of the pump and hose shown inFigure 2;

Figure 4 is a transverse section taken on an enlarged scale through the hose shown in- Figures l, 2,.-and- 3;

Figure 5 is an enlarged detailed perspective of one modication and shows the coiled portion of the hose in detail;

Figure 6 is a similar View of another modication; V

Figure 7 is a transverse section through the hose of Figure 5 being taken on an enlarged scale and about on the plane represented by the line 1-1 of Figure 5; and

Figure 8 is another sectional view through the form of hose shown in Figure 6. This view is taken on an enlarged scale and about on the plane represented by the line S-S of Figure 6.

Referring now to the drawings wherein like reference characters denote corresponding parts and rst more particularly to Figure l, an automobile is represented at A. This automobile includes a gas tank designated I and which tank includes the usual spout II which is employed for the purpose of filling the tank with gasoline. A gasoline pump is represented at P and a hose referred to generally as H conveys gasoline from the pump P to the spout I I.

It is evident that if the hose H is short, as are the present day hoses of this type, the car A must be parked close to the pump P; otherwise, the hose will not reach and the gasoline cannot be dispensed to the car. However, with the longer hose H, as provided by this invention, a much greater latitude is aorded in the position which the car A may assume with respect to the pump P.

Referring now more in detail to Figures 2 and 3, the pump P is shown as including an outlet tting at I2. The hose H at one end carries a coupling I3 which is connected to the tting I2. The other end of the hose H carries a discharge nozzle I4 which, when the hose is not used, is positioned in a supporting bracket i5 carried by the pump P.

The hose H includes a section intermediate its ends which is encased by a coil spring IS. This spring IS is shown in detail in Figure 4 and may be made from any appropriate spring wire which has the ability of causing the intermediate section of the hose to assume the coiled position depicted in Figures 2 and 3. This coiled condition presents the coils designated C1, C2, and C3.

It is evident that with the presence of the coils Ci, Cz, and Cs it is possible and entirely practical to support a long length of hose from the tting I 2 and bracket I5 in the manner which is now customary in this field. When an operator is desirous of using the hose, he merely removes the nozzle I4 from the bracket I5 and pulls the hose out suiciently far to reach the spout II of the automobile A. If the automobile should be removed, the maximum distance from the pump, the hose H will be stretched out sufficiently straight such as represented by the broken line portion of Figure 2, which is designated I'I. If the automobile A should be just a little closer, the hose H will have a slight coil or bend therein, as represented by the broken lines at I8 of Figure 2.

It is still possible to accommodate close positioning of the car with respect to the pump as the broken line condition of the hose represented at I9 in Figure 2 shows a full coil in the hose. Thus, the car may be positioned under a wide range with respect to the pump P.

First modification Referring now more particularly to Figures 5 and 7, a modified form of the invention will be described. In this form, al1 of the other structure above described remains substantially the same with the exception that the coil spring I6 is replaced by a leaf spring 20 that is embedded 5 in a strip 2| of a rubber composition that is comparable to the wall structure 22 of the hose. The normal tendency of the spring 20 is to cause the hose H to assume the coiled condition illustrated.

However, the hose may be pulled from this coiled position when the operator exerts suicient force to overcome this tendency of the spring 20. When the distorted force is removed, the hose retains in its coiled position.

Second modification Figures 6 and 8 develop still another modification. In this form a casing 23 of a rubber composition or comparable material partially encases the circular wall structure 22. The casing 23 has free edges 24 and 25 in each of which is embedded the spring strips 26 and 27, respectively. The casing 23 extends over the intermediate section of hose H which is to be coiled when the hose is not used, and the spring strips 23 and 21 perform this function in the manner above described.

While preferred specific embodiments of the invention are hereinbefore set forth, it is to be clearly understood that the invention is not to be limited to the exact constructions illustrated and described because various modifications of these details may be provided in putting the invention into practice within the purview of the appended claims.

What is claimed is:

l. In a gasoline dispensing hose, a length of hose having a wall structure dening a conduit therethrough, a rst opening at one end of said hose, a second opening at the other end of said hose, said Wall structure having an intermediate section, a strip anchored to said section on the outer side of said wall structure and extending longitudinally therealong, and a leaf spring embedded in and extending longitudinally along said strip, said leaf spring normally maintaining said section in a coiled condition.

2. In a gasoline dispensing hose, a length of \hose having a wall structure dening a conduit 50' therethrough, a rst opening at one end of said hose, a second opening at the other end of said hose, said wall structure having an intermediate section, a casing partially enclosing said section and presenting free edges, and a spring strip embedded in each of said edges, said spring strips normally maintaining said section in a coiled condition.
