s claims;

' This inventionreiates to dispensing devices for linternal combustion engine motor fuel and more particularlyV it relates to `-dispensing devices wherein hose storing means is provided, more specically, a hose reel, upon which the hose is adapted to be wound and unwound so that a relatively short length or relatively longer lengths of the hose may be utilized in dispensing operations. l v

Among the objects of the present invention are to provide a service station pump construction havingfa hose reel within the lower portion oi the housing, the housingbeing provided with an adjacent aperture through which the hose is adaptedto extend, in combination with guide (DLA 299-78) means for the hose which will maintain the hose Y on the reel and prevent' the hose from wrapping about the hub portion of the reel; to provide a hose reel construction involving a relatively tall housing having a hose reel within the base of the housing upon which the flexible hose of the dispensing line ris adapted to be vnormally coiled, such housing at a basal portion directly opposite the hose reel having an opening therein through which the freeend of the hose is adapted to pass, said' opening being provided with anti-friction guide means disposed so that a relatively shorter length of h ose extending through this opening and normally suspended from a nozzle support located adjacent the top of the housing may be extended in all directions relatively to the housing and while in such direction may be pulled through the opening with a minimum of sharp bends therein and with a minimum of effort; to provide an economical, compact reel construction for coiling the `hose Within the housing; to provide 'a reel construction and associated latching'mechanismtherefor for holding the reel with the ho'se in extended position and whereby a pull on the hose at the nozzle end will either latch the hose or release the same for retrieving movement into the hose housing; to provide guard mechanismin association with the reel for preventing the hose from jumping off the reel during either the winding or unwinding operation; and to provide these and other objects-of invention as will be apparent from a perusal of the following specification when taken in connection with the accompanying drawings, wherein:

Figure 1 shows a conventional type of hose reel dispensing device embodying the present inveniOn; v

Figure 2 is a' view showing thel hose reel and latch mechanism in unla'tched position;

Figure 3 shows the lower structure of the dispensing device'r and discloses thevpurpose of the guides in associationwith the latching means; Figure 4 is a cross sectional viewY of the reel construction; l y A 4 L Figure 5 isfa viewshowing the use of a short length oi hose for illling an automobile that is closeby; e'

Figures 6 and 7 are enlarged views of the latching mechanism.` n l Referring'now to the'drawingsy in detail,.the pump is used in association with an underground tank l adaptedto hold a quantity of liquid fuel for internaicombustion engines. such asL gasoline and the like. From thetank I extends the usual type of suctionl pipe, 2 having at itslower end the usual foot valve. The pipe`2 extends upwardly to a motor driven pump 3 disposed. within a housing 4 of the dispensing unit. The. pump is driven by the usual type of electriomotor'having an actuatable switch.` 'I'he pump is connected to a meter 5 by means of a pipeV 6 -forming a part of the ow line; and the discharge side ofthe meter is connected by means of apipe 1 toa sight gauge 8, the discharge side of which is connected to a pipe 9. The pipes 2, `i5, 1 and 9 form the stationary part of a dispensingline which is located within the housing. Connectedto this stationary dispensing linethrough lthe intermediary of the hose storing means, herein shown specifically as a hose reel, is a fiexible hosen which is adapted normauy to be stored upon the hose lstoring mechanism and which on 4being wound on or unwound from such rstoring mechanism emerges from the housing through an opening in a lower basal portion of the housing, hereinafter referred to, and thenwhen the hose is not in use extendsI upwardly'longitudinally of "the housing a distance `equal to substantially twothirds the height of the housing. At, its opposite end the hose I3 is providedwith a terminal nozzle. In the present instance, the nozzle is'provided with a valve and amanually actuatable ycontrol member therefor for controlling the dispensing operation after the pumplngmeans or liquid forcing means has been actuated. f

Referring particularly toFigure'l, it will/be noted that the.l hose storing mechanism is'herein shown speciiically asa hosel reel and whichin ydetail is ysupported on a cross :brace l5 supported from the four luprights'of the housing 4. vThe cross brace |5has a central hub-like portion Il and a vertically upstanding .support The hose reel is supported atone endgonly from the cross brace I5. The support 4I5 is provided withza centrai hollowed out hub portion 23 connected-by a a threaded opening 25 to receive a stationary sleeve 21 which extends centrally of the hub portion and forms a liquid carrying conduit. The

opposite end of the sleeve 21 is externally threaded to receive a ball bearing raceway and retaining nut 29. The raceway forms a bearing for the rotatable portion of the hose storing reel. 'I'he opposite and of the sleeve 21 opens into a chamber 3| formed by a hollow, rotatable casting 38, which is formed on its extreme end 35 with means for attaching switchcontrol apparatus as shown in Frank B. Eilers application for Liquid dispensing device, our Case No. 28, Serial No. 357,535, filed September 18. 1940. The hub portion is bolted to a spacing member.39 of the reel. which forms a seatior the circular hose. The spacing member carries thereon two sheet metal annuli 4| and 43 which form the storage space for the hose which is coiled therebetween. The spacing member 89 is provided with a plurality of laterally extending spacing lugs 44, through the end of which bolts 85 pass for attaching a spring housing 81 and the reel annuli thereto. This also forms a support for an annular or disk-like bracket 49 carrying on its periphery six latch actuating pins 5|. These pins are mounted in a exible support 53 comprising two sheet-metal half cups compressing therebetween two rubber washers 55 and 51 whereby to deaden the sound when the pins contact the latch mechanism hereinafter referred to. 'Ihe outer end of a coil spring 58 passes through an opening in the spring housing I1 and is looped around the edge of the opening 59 formed and fastened 4 in such position. The inner end of the coil spring 58 is looped about alpin 53 and bent back on itself and fastened. The pin is flxed in the extending hub-like portion I8 of the casting I5.

' '111e hollow hub member 33 is provided with an internal conduit 85 which communicates with the passage 3| thereof. and the chambered portion 55 is provided with a threaded outlet 61 to receive the inner end oi' the hose which is adapted to be coiled on the hose reel. In addition, the member 3| is provided with an internal wall 68 which surrounds a coll spring 1|, which, in turn. surrounds the sleeve 21 for pressing a yieldable packing laterally against rings 88 and ring 15 and inwardly about the stationary sleeve 21. At the opposite end the spring abuts and presses against a suitable wall 1l of the spacing casting 38. By this construction the hub member 99, the reel and the spring housing rotate on and relatively to the support sleeve 21 and bracket I5, while at the same time preserving a liquid-tight connection therebetween.

The stationary bracket I5 is provided with an upstanding, laterally extending portion 85. The laterally extending portion 85 forms a support for a pivot connection 81 on which van elongated latch 89 is pivotally mounted. The latch 89 is provided witha leg 9|, which is adapted in shifted position to abut a'stop pin 83 mounted on the bracket 85, and in addition the latch member is provided on its under edge with a relatively long, substantially straight edge 95 terminating in an inwardly extending relatively deep slot I0 l having a short straight side wall 99 and forming a cam 91. The opposite wall |08 of the slot projects as at |85 well beyond the opposite wall 99 of the slot, and thence the latch curves inwardly as at |01, tapering to a somewhat rounded, elongated leg |09. This latch is adapted to cooperate with a series of latching pins 5I disposed in equally spaced relationship en the periphery of the rotatable reel disk 49. In the operation of this latch mechanism it is to be noted that it reciprocates up and down as the pins rotate thereunder, but the latch is always kept substan- Atially horizontal by its mounting on the bracket The hose reel operates normally anti-clockwise when the hose is being unreeled from its lower periphery. In this direction ot rotation the stop pins 5| contact the surface 95 of the latch, raising the latch about its pivotal pin 81. When the stop pin 5| reaches the downwardly cammed portion 91 in this direction of rotation, the pins move the latch upwardly and pass freely thereunder because the latch is free to move upwardly, i Whenever the hose has been extended to its desired length, the coil spring 58 tends to rewind the reel and in so doing the pins 5I move backwardly in a clockwise direction and rst strike the curved cam surface |01 of the latch. If it is desired to latch the hose reel in thus extended position, this retrieving movement of the hose and the reel will be purposely made relatively slow and under this slow movement the pins 5| pass first under the curved cam portion I 01 and the latch will have suilicient time to drop after the pin has passed the point |05 so as to cause the pin to enter the slot 0|. Under this arrangement the reel is held against further movement with the hose maintained in extended position, so that the operator need not maintain a tension on the hose. To unlatch the hose the operator pulls the hose out slightly, which rotates the reel in an anti-clockwise direction and brings the pin 5| out of the slot |0| and beyond the cam surface |01 some distance. The hose is then released with a quick movement and the reel spring will spin the reel in a clockwise direction at a sumcient speed so that when the pins again pass the cam point |01 or the point |05 the latch cannot act quickly enough and the pins 5| will be cammed past the slot |0| before the point 91 can contact the latch and direct the pin into the slot l0 I. As long as the reel is turning in a clockwise direction at sunlcient speed, the latch will be impotent -to operate. It is only when the speed is slow that the weight of the latch will cause it to fall upon `the pin and direct the pin into the slot |0| When or clattering. It will be noted that the pins 5| are likewise resiliently or rubber clad so as to prevent noise in operation.

Means is provided in association with the housing, the reel mechanism, its latching mechanism,

and the reciprocable hose tor preventing the hosev from departing or coming oif the reel during either the winding or unwinding movement. At times the latching mechanism, during the retrieving or winding-up movement of the hose, locks the reel from further movement before the hose, which has been withdrawn from the housing, is fully wound upon the reel. Thus there is presented a condition where the reel is locked from movement and an extra length oi hose is onv the outside of the housing. In such a condition, heretofore operators have attempted to tuck or force this extra length of hose through the opening in the base of the housing into the space at the bottom of the housing. Any attempt of in the well in the base of the housing or to move laterally to a position oi! the reel whereby, when the hose is subsequently pulled out, it will come completely oil' the reel and lodge. To prevent this occurrence, means is provided in association with the housing, the reel, and the hose for preventing coming off the reelV within the housing either upon the unwinding or winding operation.

The bottom of the dispensing housing is provided with a preferably cast metal base to which is attached the guard bracket III. 'Ihe bracket I I i is provided with a hose guidingroller I Il disposed to rotate about a horizontal axis in slightly spaced relationship from the reel as the hose uncoils from the reel. The bracket III is provided with an angularV support lil on which is mounted two additional rollers H5, which are inclined vertically rearwardly and lie with their inner peripheries just within the planes of the vertical disks of the reel so as to vertically guide the hose as it comes off or goes onto the reel. It lis to be noted that the bracket III is disposed within the housing to the rear of the opening. The rollers H guide the hose oir the reel inea direction toward the opening in the housing. In addition to these rollers, thevopening in the housing is likewise provided with rollers. -For instance. there is a pair of rollers, an upper H8 and a lower i2| which are spaced apart and are adapted to guide the hose through the opening in such a, way as tosprevent abrupt bends in the hose. Cooperating with the upper and lower rollers H9 and i2| are two vertically inclined rollers i23 and |25 on each vertical side of the opening betweenl which and said upper and lower rollers the free end of the hose isadapted to pass. These inclined rollers are formed in double concave f ormation so as constantly to direct the hose toa location substantially midway between the rollers. It will be noted that the lower roller I2l is disposed forwardly of the upper roller H9 and that the lower roller I2I is mounted substantially outside of the opening of the housing. This is likewise true of each roller of the inclined pair. By this arrangement the hose is frictionlessly directed through the opening of the housing. These rollers thus provide a universal bearing or pivotal mounting about which the free end of the hose may be swung in any desired direction and with the opening as a point of pivot,

and at the same time the rollers permit, if desired, -an additional length of hose to be withdrawn through the opening while the hose is extended in any desired direction.

By reference to the construction of the reel mechanism, it is to be noted that it is a very simple structure, one which is liquid-tight and which permits the easy rotation of the reel mechanism relative to the stationary portion thereof, and in addition provides a pivotal mountingfor the latch mechanism in association with the stops carried by the confronting face of the reel mechanism. The foregoing provides a very compact relation and a structure which is reliable in operation, cheap in construction and assembly, and silent in operating the reel in either direction.

The construction of the friction rollers at the basal portion of the housing in cooperation with the rotatable reel mechanism and the opening in the housing is one which eiectively guides the hose as it coils upon and uncoils from the reel mechanism, and also eiectively guides'the hose through the opening in the housing and permits the bending of the hose in any desired direction. In addition, the guard bracket at the base of the housing is peculiarly effective. It has been found by experience that many times when the hose is being'returned to its-'nozzle support, the latch will tend to stop the reel before suiilcient hose is retrieved. which condition causes a surplus amount ofA hose to accumulate outside thehousing. To cure this. the attendants have hereto fore attempted to force this extra hose into the casing, and due to the fact that the reel could not rotate and take up the surplus, the extra hose many times has been forced into the pit located below the pump housing. In the present instance, the guard rollers H5 and ill in combination with the adjustable guard I1 prevent the hose from jumping' on the reel during the unwinding and rewinding operation. It will be noted that the guard I1 is adjustably disposed relatively close to the edge of the reel disks 4i and 43, so that the hosecannot pass laterally of the reel at this point, and, in addition, at the front of the reel the guard IM is adiustably disposed on the bracket lil relatively close to the periphery of the reel at the front of the housing: this is the horizontal roller,vand 4is combined with the two spaced apart, backwardly inclined rollers H5, which lie, as heretofore stated, in the vertical plane ofthe vertical reel sides'or ends Il and Without these guards in position, the hose could leave the reel, and on the next dispensing operation the attendant, in withdrawing the hose, would pull the same oil the reel and it would ltend to wrap about the hub, which would tend to damage the hose, and cause jamming and prevent operation. This would cause the attendant to open the housing or the pump to replace the hose upon its reel. The guards in the position heretofore described prevent any excessive? hose from leaving the reel or at least from get'- ting out of alinement. Even if the hose should be forced into the pit, upon the next withdrawal, the hose will return to its reel. These guards can be of any design, such as a metal shield entirely about the reel, or rollers, or other types of retainers. They cooperate most eiectively with the latch mechanism for maintaining the hose on the reel in any desired angular position of the reel mechanism.
