Claims (Cl. 299-77 This invention relates to improvements in service station dispensing apparatus of the type in which the servicing hose is extensible from and retractible into a housing that contains the usualdispensing pump, meter and, register.

The extra hose, that enables extension of theservice range, may be stored inside the housing, as shown for example in Hope Patent No. 2,242.749, dated May 20, ,1941, and acted on directly by a weight or other suitable retracting means. It is necessary to have the hose so mounted that a portion of it may move into and outof the housing and may bepulled in various directions while outside the housing.

This invention is concerned with, andhas forits object, the provision of improved means for guiding the hose .during its passage out of and into thehousing and immediately adjacent thereto.

More particularly, the invention has for an object the provision of an arm, which is swivel led to one upstanding side Wall of the housing for swinging movement aboutahorizontal axis and is provided with a pluralityof suitable guides for the hose. This arm, which normally hangs downwardly when the hose ,is retracted, will be swung upwardly, when the hose is pulled toward the front or the "backof the housing, and guide the hose around but out of contact with a corner of the housing.

The invention has for another object theconstruction of the swivelled guiding arm in two pivotally connected sections, each having a set of guides, which sections will be relatively moved when the hose is pulled straight outwardly from that side of the housingthrough which itpasses, in order to carry the two .setsof guides more nearly int-o alignment, thereby lessening the resistance to movement of thejhose and providing an easier pull and less wearonthe hose.

The invention will be disclosed with referenceto the illustrative embodiment ofit in the accompanying drawings, in which:

Referring .to these drawings; Figs. 1 and 2 showaihousing .for the elem entsof a service station apparatus such as is commonly used .for dispensing measured,quantities of .motor fuel and the like. This housing has a base 1, side .walls 2 and 3 and front and rear walls 4 and -5, respectively, upstanding from the base, and a top wall 6. The front and rear walls 4 and 5 usually have ,windows, such as 7, through whichlhe indications of .a register, located inside the housing, are visible. The fluid is dispensed through a flexible hose 8 having on its outer end the usual valved dispensing nozzle 9, .which when not in use, rests on a suitable support 10with the delivery end of the nozzle disposed in a s Q-called ,boot .or shielding recess 11, provided in the side wall 3 of .the housing. Fluid maybe forced through the hose by any suitable pumping means and measured, if desired, by any suitable meterwhich drives a suitable register, .all these elements usually being located within a housing such as that described. These elements are old and well known in the art and accordinglydescription and ,illustration of them is not necessary to an understand- .ing of thepresentginvention.

This invention is concerned primarily with the guiding of the ,hose .-8 ,intoand outof the housing. The extra ,hose, that enables extension of the service range when desired, is stored inside the housing after the general manner disclosed in the above-identified Hope patent. Theinner end ofithehose 8 (,Fig. l) is attached to the depending end of a pipe 12, ,which carries the pumped fluid. From pipe i 2, the ,hoseextends downwardly to and around a weighted sheeve 1.3 and thence upwardly toward the top .of the housing where it passes laterally across the housingover suitable guide rolls 14 and ,15 to and through an exit in the side wall 3, such vexit being. provided through the swivelled end of the swing- .ing hose-guiding arm of this invention.

This swinging arm is preferably constructed .in two ,parts an inner .part lfi, which isswivelied atone end..to the side wall 3 of the housing, and an outer. part 17, which is pivoted at its innerend to the outer end of the part 16. The ends. of these two parts are provided with suitable guides for ,hose fi. As shown in Fig. 3, the inner end of arm 16 has a hollow hub 18, rotatably engaged in a bearing sleeve 19 which is fixed with its .axis horizontally disposed by means of bolts 20 that clampa flange 21 on thesleeve towall 3. The bearing sleeve 19, as herein shown, is lined with a nylon sleeve 22. The hub 18,has a flange 23 which abuts flange 21. The flange 23 (Figs. 3 ,and @8) has projecting inwardly from its inner face in angularlyrspaced. relation .three pairs of ears 24. The .outer ends of the ears of .each pair. areinterconnected by an arc-shaped ,Wall 25. These ears .and walls extend inwardlybeyondthe hub 18 as shown ;in-Fig. 3 and slightly beyond the inner end of bearing sleeve 19. The three walls 25 (Fig. 8) are rotatablyengagedwith the lining 22 of the bearing .19. .Each arc-shaped wall 25 is grooved and these three .grooves (Fig. 3.) receive .a snap ring 26, which abuts .the inner end of bearing19 and holds:the arm 16 against axial displacement in its bearing. Extending between and :fixed atits endsin. each pair of ears 24 (Fig. 8) isa pin 27 which carries a roll 28 confined endwise between the ears. The hose '8 passes through the hollow hub of arm 16 and between the three rolls 28 which form a guiding eye forthe hose.

The arm 16 extends outwardly and downwardly from the flange 23. This arm has two right-singularly turned side webs 29 (Fig. 2), which are parallel at the outer part of the arm and then curve outwardly as they reach the flange 23 and merge therewith. A roll 30 is located between the parallel parts of webs 29 and is supported by 3 a pin 31, mounted near its ends one in each such parallel parts and projecting therebyond. The outer arm 17 has at its inner end two parallel right-angularly turned side ears 32 which receive between them (see Fig. 5) the parallel parts of webs 29 and which receive one in each the projecting ends of pin 31, such ends being suitably fixed thereto. The arm 17 is thus pivotally connected to arm 16 for swinging movement about a horizontal axis disposed at right angles to the axis about which arm 16 swivels. The swinging of arm 17 on pivot 31 is limited by stops 33 (Fig. 1) fixed one to the outer side of each web 29 near the outer end thereof. The outer face of each stop 33 is normally engaged by parts 34 of the ears 32 on arm 17 as shown in Figs. 1 and 3 but the arm 17 can swing counterclockwise until lugs 35 on ears 32 engage one with each of the upper faces of stops 33 as shown in Fig. 7.

The lower end of arm 17 is divided into tWo branches 36 (Fig. 4) which are initially parallel and then diverge outwardly. The parallel portions support between them a roll 37, which is mounted on a pin 38 suitably fixed at its ends one in each of said portions. The outer and diverging end of each branch 36 has fixed thereto one end of a pin 39, which carries a roll 40, held against axial displacement by a snap ring 41, engaged in a groove in pin 39. The axes of the three rolls 38 and 39 are disposed in triangular relation and these rolls form between them a guiding eye through which hose 8 extends. The axis of this guide is at right angles to the axis of the guide afforded by the three rolls 28 and normally lies vertical or substantially so, as shown in Fig. 1. The hose 8, when not in use, extends downwardly from the outer end of the outer arm 17 to a location near base 1 and thence upwardly with its nozzle resting on support 10, as shown in Fig. 1.

In use, the operator removes the nozzle 9 from support and carries it to the tank of the automotive vehicle that is to be serviced. Depending on the position of such vehicle with relation to the housing of the dispensing apparatus the hose will have to be pulled in various directions in order to reach the tank. In some cases it will be necessary to pull the hose sidewise toward the front wall or the rear wall of the housing and in such cases, the arms 16 and 17 will function as one without relative movement about the axis of pin 31 and will simply swing about the axis of the hollow hub of arm 16. The two guiding eyes afforded by the two sets of triangularly disposed rol'ls plus the intermediate roll 30 will guide the hose in a right angle bend of large radius and enable the hose to be extended if necessary by a relatively easy pull on the hose. In other cases, it may also be necessary to draw the hose around the front or back wall of the housing and in such cases, the two arms 16 and 17 will swing about the axis of the hub of arm 16 without relative movement, into a position, such as shown in Fig. 6, where the hose can be brought around a corner of the housing without contact therewith and thus with less frictional resistance to pulling on the hose for outward extension, when desired, and without causing abrasion of the walls of the housing. Whenever the pull on the hose is directed outwardly from side wall 3, the pull will swing arm 17 outwardly and upwardly about the axis of pin 31 until the parts are positioned as shown in Fig. 7. The axis of the two guiding eyes will be brought more nearly into alignment, thereby enabling the hose to be extended with less effort and also with less wear.

The invention thus provides in a service station dispensing apparatus, of the type in which the servicing hose is extensible from the housing by a pull on the hose and retractible into the housing when the pull is released, an improved means for guiding the hose with respect to the housing so that the hose may be freely pulled in any direction and so that when it is pulled around a corner of the housing, it is maintained out of contact with the housing to avoid abrasion thereof and also lessen the resistance to pull on the hose.

What is claimed is:

1. In a fluid dispensing apparatus, having a housing with upstanding front, rear and side walls and a top wall, a dispensing hose stored in part within said housing and extending out of the same through one of said side walls, a first hose-guiding arm having a tubular hub mounted on the last-named side wall near the upper end thereof for swinging movement about an axis normal thereto and affording a first guiding eye through which the hose passes out of said casing, said first arm extending outwardly from the last-named side wall terminating with its outer end spaced therefrom and tending by its weight to hang downwardly, a second hose-guiding arm having its upper end pivoted to the outer end of the first arm for swinging movement about an axis parallel to the last-named side wall and tending by its weight to hang downwardly from the outer end of the first arm, cooperating stops one on the first and one on the second arm for limiting the extent of swinging movement of the second arm toward the last-named side wall to a position substantially parallel to and substantially spaced therefrom, and a second hoseguiding eye on the lower end of the second arm, the hose passing from the first eye to and through the second eye and thence downwardly therefrom, said second eye encompassing the hose peripherally to a suffioient extent to prevent the hose from being moved out of the eye in all directions radially of the latter, the axis of said second eye being substantially parallel to the second arm, a pull on the hose in a direction outwardly from the lastnamed side wall causing the second arm to swing outwardly therefrom and upwardly moving the second eye more nearly into alignment with the first eye, a pull on the hose toward either the front or the rear wall swinging both said arms about the axis of the first eye and carrying the second eye outwardly toward either the front or rear Wall and positioning it to guide the hose around and out of contact with the corner where the last-named side wall intersects either the front or the rear wall.

2. The combination, as claimed in claim 1, in which a second pair of stops is provided one on the first and one on the second arm to limit the extent of outward swinging movement of the second arm relatively to the first arm.

3. The combination, as claimed in claim 1, in which a guide roll for the hose is mounted on the pivotal connection between the first and second arms.

4. The combination, as claimed in claim 1, in which each guiding eye comprises a plurality of rolls angularly spaced about the hose and confining it against movement out of the eye in all directions radially thereof.

5. The combination, as claimed in claim 1, in which the axis of the tubular hub is located midway between the front and rear walls and the radial distance from the axis of the first eye to the second eye is approximately equal to half the width of the last-named side wall.
