I Claims. 1;

Thisinvention. relates tohose reeling mechanism. More specifically; it. is concerned with hose reeling mechanism. intended to be used in dispensing petroleum products like gasoline or oil at airports in servicing planesand other'fiy-ing craft.

In hose reeling. mechanism, as ordinarily constructed, the reel on which: thehose is wound is horizontally arranged; and in instances where the liquids are metered, the sealers require the hose to be drained'after each delivery toprevent cheating of the purchaser. With. a. horizontal reel however, some off the liquid. will: always: remain in the bottom of thelconvolutions or turns ofthe hose. Since trapped liquidacannotbe completely removedby pump action, it isimpossible to determine, with. any degree of accuracy, any fixed amount that. should be allowed the'purchaser as a deduction from the. reading of. the meter at the time asale is made;

The chief aim of. my'iHV8I1l7iOl1',iS-.t(] overcome the drawbacks to which reference is madeuabove. This objective is attainedinpracticeashereinafter more fully. disclosed, through. provision: of

an improved hose reeling mechanism. adaptedfor installation in a pit below the-.groundlevel, in which the reel is vertically arranged and rotatively supported, in which the hose extends up through an aperture in a cover over. the pit, and

in which the reel has aspiral ledgeatthe bottom whereon the lowermost convolution of the hose is supported with the succeeding convolutions piled up upon it to insure complete drainage.

In connection witha hose reelingmechanism having the foregoing attributes, it is a further aim of my invention to provide automaticallyoperative means for guiding and controlling the I hose to predetermine uniform distributionof its turns on the reel during winding, as well as to prevent snarling thereof. incident. to withdrawal from the pit.

Still another object oiLmy invention is to provide a simple and reliable power drive means for driving the reel in winding,zwith.means which will allow reverse rotation of the reel by-manual pull upon the hose inunwinding.

Other objects andtattendant advantages will appear from the following detailed description of the attached drawings, wherein: Fig: 1 isa-fragmentary view in vertical section of 'a-pitrcontaining my improved hose reeling mechanism.

As herein exemplifiedmy improved hose reeling mechanismcomprises a vertically-arranged reel 5. with a cylindric drum which mayv beconveniently fashioned from sheetmetal, and with spoked wheel-like ends 6 and 1" respectively at the top and bottom. Extending axially. down into. the drum through av central hub. element 8 of the top wheel end 6 is a shaftBwhereofthe upper end is journalled in a bearing I0. From Figs. 2 and 3 itwilli be notedthat'the bearing I0 is fixedly supportedv by a channel'beam I I forming part ofastructural iron skeleton framework lzset into a pit l3 below the ground level. At its lower end;.'the shaft 9 is securediin the upstanding. boss l5a, on one'elbow l5 bolted to the bottom head T of the drum 5. The downward portion of the elbow l5 extends axially through the lower drum head 1 and mates with a fixed elbow it, they two elbows together-constituting what is ordinarily known as a swivel'fitting which, in this instance, serves torotativelysupport" the reel 5 at the bottom. The' fixed-elbow [6 of the swivel fittingis weldedor otherwise rigidly se-' cured to a cross member I! of the framework- 12', and is in communicationbywayof apipe l8 with a source of-supply (not-shown) 1 of the liquid commodity 'to' be vended; The" delivery hose'; designated 20,- is connected to-the horizontal outlet branch-ofthe elbow IS-andcoiledabouttlie drum with its free end portion passing tangentially from the drum as in Fig. 2-and -then upward and outward through anaperture -2-l in a cover plate 22 that closes the pit l-3 at the top-as in Fig. 1. A spiral ledge 23" having a circumferential ex-tent of about" 270*-periphera1ly of "the bottom head 1 3 wheel affixed to the drum shaft 9 immediately below the upper bearing ID for the latter. The sprocket pinion 28 is connected to the shaft 21 by a clutch device 3| of a well known commercial type having a release plunger 32.

The means which I have devised for controlling the hose 20 to insure even winding thereof on the drum 5 comprises a flanged wheel which is circumferentially configured to conform to the cross section of the hose, and which is adapted to roll on top of the convolutions or turns of the latter as best shown in Fig. 1 during winding and unwinding. The wheel 35 revolves freely about a horizontal axis stud 36 projecting laterally from a slide carriage 31 which is constrained to movement on

guide rods

38, 39 extending vertically between the horizontal member H at the top of the framework l2 and a corresponding member 40 at the bottom. As shown in Fig. 2, the carriage 31 is attached to an endless chain 4| which is trained about

sprocket pinions

42 and 43 whereof the latter rotates freely'about a lateral stud 44 on a bracket 45 mounted on the frame member 48. The sprocket wheel 42 is afiixed to a horizontal axis shaft 41 rotatively supported 'by another bracket 48 on the framework, together with a miter gear pinion 49 which is'in mesh with a companion miter pinion 58 free to rotate about a stud 5| upstanding from said bracket. Secured to the pinion 50 is a sprocket wheel 52 which, through a chain 53, is adapted to be driven from a sprocket pinion 54 from the output shaft 21 of motor 25.

As shown digrammatically in Fig. 4, the motor 25 is connected to a three wire electric power limit switch 58 which, see Fig. 1, is secured to the :1

guide rod 39 near the top for actuation of its plunger 59 by the carriage 31 when the latter is fully elevated and the hose 20 is completely wound up on the reel. Also embodied in the wiring system is a solenoid 80 which, see Fig. 2, is supported by a standard 6| from the frame of motor 25 with its armature 62 inaxial alignment with the actuating plunger 32 oftlie clutch"3|, and subject to a spring 63 tonor mally hold the clutch released. In order to prevent kinking of the hose 2|] as it is passed downward into or upward from the pit and tangentially to or from the drum 5, I have provided a group of guide rollers 65, B8 and 61 which are supported for free rotation by a laterally extending bracket 68 welded to the frame l2 at the top of the latter.

Although, as already stated, the clutch 3| is of a well known type, its construction will be briefly described in connection with Fig. 5 in order that its use in connection with my invention may be properly understood. As shown, it includes a drum element 18 which is secured to the shaft 21 by a set screw 1|. Rotatable about the lower portion of the drum element 18, with interposition of a pin bearing 12, is a collar 13 whereto are bolted the sprocket pinions 28 and 54. Anchored in an annular groove in the top of collar 13 and extending upward about the top portion of element 10 is a coiled spring 15 whereof the free end is coned. The plunger 32 is slidable endwise in the axial bore of the drum 18 and urged outwardly by a biasing spring 16. Extending crosswise through theplunger 32 is a pin 11 which is constrained in a diametral slot in the top of the drum element 18, with its ends engaging through aligned apertures in a ring 18 which is flared to correspond with the cone taper of clutch spring 15. Normally, the collar 13 is free to rotate about the drum 10. However upon depression of the plunger 32 and the ring 18 being brought into engagement with the top of spring 15, the latter is caused to bind upon the drum 15 with the result that the collar 13 and the sprocket pinions 28 and 54 will be clutched to and driven by shaft 21.

Operation With the clutch 3| normally released, the hose cident to which the reel 5 will freely revolve on its axis. Through the

gearing

30, 29, 28, 54, 53, 52, 50, 49 and chain 4|, the carriage 31 will be concurrently moved downward on the

guide rods

38 and 39 for control of the hose by the flanged wheel .35. Upon delivery of the desired amount of the liquid commodity, the button of manual switch 51 is pressed to start the motor 25, with incidental energization of the solenoid 68 and setting of the clutch 3| for drive of the various gear connections by power from said motor. Through the gearing, the reel 5 is rotated to draw in the hose 20, while the carriage 31 is compensatively elevated to control, through its flanged wheel 35, uniform winding of the hose about the reel. Eventually, current flow to the motor 25 will be interrupted through opening of the limit switch 58 by the carriage 31 when the desired amount of the hose has been wound upon the As the winding takes place, the successive convolutions of the hose will be piled one upon another, all at the inclination determined by the spiral ledge 23 at the bottom of the reel so that complete draining may take place. It is to be understod that the push button switch 51 is suitably located for convenience of ready access above ground.
