1'7 Claims.

Our invention relates in generalto dispensing apparatus and has more particular reference to apparatus for the dispensation of fluid such as gasoline, although the invention may have more general application; and our present application comprises a continuation in part of our co -pending application for Letters Patent of the United States on an improvement in Dispensing apparatus, Serial Number 633,563, flled September 17, 1932, Patent No. 2,059,442.

An important object of the present invention is to provide apparatus for the dispensation of fluids through a preferably flexible dispensing hose which, when not in use, may be housed entirely within a casing forming a part of the dispensing apparatus in concealed position.

Another important object is to mount the flexible fluid dispensing hose in position normally retracted completely within a housing, the hose mounting equipment permitting the same to be drawn from the housing into dispensing position when dispensation of the liquid is to be accomplished; a further object being to form the housing with improved closure elements for covering the opening through which the hose may be drawn from the housing when the apparatus is not in use; a still further object being to provide cover means for said opening adapted to be securely locked up to prevent unauthorized tampering with the dispensing hose.

Another important object is to provide dispensing apparatus of the character mentioned wherein the entire apparatus, including the housing, is adapted for overhead mounting as on the 3.3 ceiling of a building structure or automobile service station.

Another important object is to provide apparatus, including a reel for carrying the flexible dispensing hose when the same is in retracted, inoperative position, including switch means cooperatively associated with the reel and operable to prevent dispensation of fluid through the hose when the same is in retracted position on the reel; a further object being to constitute the switch means to automatically condition the dispensing apparatus for operation as and when the hose is unwound from the reel.

These, and numerous other important objects, advantages, and inherent functions of the invention, will become apparent as the same is more fully understood from the following description,

To illustrate our invention we have shown, on the drawings, a fluid dispensing device including a preferably flexible fluid dispensing conduit or hose ll terminating in a preferably valve controlled dispensing nozzle I3, and means to force fluid to and through the hose under pressure for the purpose of dispensing the same. The fluid forcing means may comprise any suitable equipment, but we prefer to employ a pump I5 driven by any suitable or convenient motive means, the operation of which may be quickly and easily controlled and to this end we prefer to drive the pump by means of an electric motor M.

In the illustrated embodiment, the intake of the pump I5 is connected by means of a conduit I! with a storage tank 2| forming a reservoir of fluid to be dispensed. The outlet of the pump I5 is connected by means of a conduit 19 with an air release and overflow device 23 having a vent 25 to atmosphere for discharging any gas collecting in the device 23 and an overflow re-' turn conduit 21 connected with the storage tank 2|. The overflow and air release device 23 is or may be connected by means of a conduit 3| through suitable metering devices 32 in the hous- 55 the fluid to the hose l I under pressure, are shown located in the building 35 at a point remote from th housing 29. The fluid forcing means, of course, may be located in the housing 29, if desired, and of course the fluid may be delivered from the tank II to the hose II by any suitable or preferred means other than the motor driven pump shown. In any event, it is desirable to control the operationof the fluid forcing means so that the operator may start and stop the same by manipulating the dispensing hose as a part of the dispensing operation.

To this end the hose, while the apparatus is inactive, is adapted for mounting in concealed condition within the housing, but may be withdrawn from the housing into dispensing position and we provide means automatically actuated by the withdrawal of the hose to concealed position in the housing in order to start the fluid forcing means in operation. Likewise, we provide means which will automatically cause the hose to be retracted into the housing at the end of the dispensing operation as soon as the hose is released by the operator. The retraction of the hose automatically functions to discontinue operation of the fluid forcing means. Any suitable hose mounting may, of course, be employed but we prefer to utilize a reel 31 located within the housing and on which the hose may be coiled when not in use. This reel preferably comprises a tubular axle element 39 which may suitably comprise a length of pipe. The opposed ends of the pipe 39 are preferably sealed by plugs 4| threaded therein and said sealed ends are or may be rotatably supported in the casing 29 as by means of the bearings 43 mounted on the inner opposite walls of the housing. The pipe 29 has means 45 fixed thereon forming a support on 'which the hose may be coiled, the means 45 preferably comprising a framework forming a substantially cylindrical drum 4'! or equivalent hose receiving framework. The hose reel 31 also is preferably formed with a conduit 49 extending radially from and connected with the pipe 39, said conduit 49 being connected With the pipe 39 at one end by means of the coupling 5|. The other end of the conduit 49 extends outwardly of the hose carrying portion 41 and is provided with a neck extending substantially at right angles with respect to the conduit 49.

One end of the hose II is secured to the neck 53 so that by rotating the drum in one direction the remainder of the hose may be coiled thereon in one direction, as indicated by the arrow 55 in Figure 7. The remainder of the hose may be coiled on the reel. Means is provided for normally urging the hose reel to rotate in a direction to so wind the hose upon the reel and to this end we provide preferably on the pipe 39 a pulley 51 on which may be coiled a flexible driving cable 59, one end of which is connected on the pulley and the other end of which is secured to an end of a spring 6|, the opposedend of which is anchored on the housing. Obviously any other suitable drum urging means may be employed. The pipe 39 outwardly of the hose supporting means 45 is a formed with a lateral opening 63 and the portion Annular seals 59 are provided in position encircling the pipe 39 to seal the openings 51 around said pipe. The seals 69 may be of any suitable character, but we prefer to utilize seals comprising annular cup-shaped elements having surfaces adapted to set upon the walls of the chamber 65 around the openings 61, packing material H being arranged in the cup-shaped elements around the pipe 39 and held in place by washers. A spring 13 is or may also be provided to urge the washers oppositely along the pipe whereby to compress the sealing material II in the cup-shaped elements and to urge the cupshaped elements into sealing engagement with the walls of the housing 65 around the openings 61. The housing 65 has an inlet opening connected with a pipe 15 forming a part of the system for delivering fluid under pressure through the sight gauge 33, said pipe I5 being connected to the discharge of said sight gauge.

When the device is in operation, fluid will be delivered under pressure through the sight gauge, thence through the pipe 15, and into the chamber 65, from whence it may penetrate through the opening 63 into the pipe 39. From the pipe 39, the fluid may be forced through the radial conduit 39 and into the hose I l.

The dispensing nozzle 13 preferably has a manually operable control valve 93, operable by means of the handle 95. As heretofore mentioned, the reel 31 is normally urged in a direction, by means of spring 6i and the cable 59, to maintain the hose in coiled position on the reel, the hose thus being normally retracted and housed completely Within the casing 29. Casing 29, however, has an opening 11 through which the hose may be drawn out of the housing, thus uncoiling the same from the reel .and causing the reel to rotate during the uncoiling operation against the tension of the spring 6|.

opening as shown at 19 to form a socket or sheath for receiving the nozzle l3 when the hose is in retracted position.

Cover means 8| is or may be provided for covering the sheath, said cover-means comprising a hinged element as shown in Figures 3 and 6 or as shown in Figure 4 said cover means may comprise a pair of sliding door elements 33. Any suitable or convenient form of cover, however, may be utilized for the purpose of enclosing the opening and enclosing the nozzle socket. In addition, we prefer to provide cooperating means on the casing and on the door element as shown inFigures 3 and 6 or the cooperating door elements as shown in Figure 4 for the purpose of locking the same in closed position in order to prevent unauthorized tampering with the dispensing nozzle and hose when the apparatus is not in use.

In the case of the apparatus of Figures 5 and the nozzle, due to the arrangement of cover 9|, the action of gravity and flexure of the hose, will project itself from the housing as is clearly shown in Figure 5 when the lock is removed, so that it may readily be grasped by the operator.

As shown in Figure 3, the lockingmeans 35 may comprise a perforated projection 91 on the housing in position to penetrate an opening 99 formed on the door element so that when the door element is closed the same may be secured by means of a padlock 95 or other suitable fastening device. In the embodiment shown in Figure 5, the-locking means may comprise adjacent perforatedprojections 81' and 89' through the perforations of'which a padlock 85 or other suit- The housing is also formed at the 0 .on the direction of rotation of the pipe 39.

able locking device may be inserted. In the embodiment shown in Figure 4, the relatively slidable door elements 83 may be formed with cooperating perforated projections 9I through the perforations of which a padlock or other suitable fastening device may be inserted when the doors are in relatively closed position.

The nozzle I3 is preferably provided with a normally closed control valve 93 which may be opened by manually depressing a valve handle 95, forming a part of the said nozzle. It is ordinarily desirable to set the fluid forcing apparatus in operation prior to the manipulation of the handle in opening the valve 93 in order that the hose may be substantially completely filled with fluid under pressure when the valve is opened and to this end our invention contemplates the provision of means for starting the fluid forcing equipment in operation automatically as the hose is retracted from the housing 29 and while any suitable mechanism may be employed for this purpose, we prefer to utilize switch means 95', preferably a sealed mercury switch mounted in position within the housing 29 to cooperate with the hose reel whereby the switch may be moved to open position by the rotation of the hose reel in a direction to wind the hose thereon, said switch being shiftable by rotation of the hose reel in the opposite direction, that is to say, in the direction caused by drawing the hose from the casing into dispensing position, to circuit closing position. The switch 95 is connected with the conductors 91 forming a circuit for the control of the fluid forcing mechanism, said control circuit being adapted when closed at the switch 95' to start and maintain the fluid forcing apparatus in operation, and being adapted when the circuit is broken at the switch 95 to immediately discontinue operation of the fluid forcing means. In order to operate'the switch 95 as aforesaid, we provide a cam-like projection 99 on the rotatable hose reel, .said projection being formed preferably on the pipe 39 outwardly of the hose supporting position 45. The switch 95 also is preferably mounted in a tilting bracket IIII having an arm I03 extending in the path of movement of the projection 99. Spring means I05 may be provided to resiliently hold the bracket IIII. The bracket IOI may thus be tilted to either of two positions depending up- In one position, the switch 95' will be closed and in the other open, and spring means I05 may be provided to yieldingly secure the bracket in both of said tilted positions. The arm I03 preferably has non-positive connection with the bracket IIII to permit the arm to yield and allow the projection 99 to pass repeatedly in one direction.

The embodiment illustrated in Figures 5 and 6 is essentially similar to the embodiment shown in Figures 1 and 2 except that the form of the casing 29 is modified in order that the casing, the hose reel, and the metering equipment may be mounted in over head position by securing said casing, for example, on the ceiling of a service station. In such an arrangement the feature of our present invention which resides in the coiling of the hose on the reel entirely within the housing when not in use is of particular importance for the reason that overhead mounting may be accomplished only where provision is made for disposing of the hose when the apparatus is not in use, the nature of the apparatus and the fluid dispensed thereby making it imperative to eliminate dangling hoses containing imflammable liquid such as gasoline. The provision of dispensing apparatus of the character mentioned adapted for overhead mounting is particularly useful in that valuable ground or floor space may thus be conserved to best advantage. Moreover, by providing for the complete enclosure of the hose when not in use, the appearance of the dispensing equipment is considerably improved and the danger of damage to the hose is substantially eliminated for the reason that the same is entirely enclosed and completely protected except when being used in dispensing operations.

Referring to the accompanying drawings relating to Figures 10 to 14, inclusive, a housing I29 serves to enclose the lower portion of the dispensing apparatus which comprises the usual fluid pump II5, connections whereby it may be driven by an electric motor III, to pump fluid from an underground reservoir (not shown) through the suction line I2I, into an air release mechanism I I9. From the latter mechanism the fluid passes through a combined check and relief valve I22, through a meter I23, through a conduit I25 to a sight glass or flow indicator I2'I mounted outside of the pump housings and thence through conduit I3I to the horizontal conduit 245 later to be described.

A clock or indicator mechanism I33 adapted to be controlled by the meter to register the volume, cost, price, etc., of the measured fluid is provided. This mechanism may be of any desired construction.

superposed upon housing I29 is a housing 2 which overhangs the lower housing as indicated at I35. Said housing 24H serves to enclose the hose reel, the hose nozzle, the motor switch and its operating means.

The conduit 245 mentioned above serves as an axle for supporting the reel 243. Support I31 serves to sustain part of the weight of the reel, hose and conduit M5. Suitable bearings I39 may be provided on said conduit to reduce the friction between it and the reel. Any desirable packing I 4| may be provided to seal the joint between the reel hub I45 and the axle or conduit 245. A cap I43 seals the hub of the reel at the side opposite to that by which the conduit enters it. If desired, shaft 245 may be provided with a trunnion I53 which may cooperate with a support I31 similar to support I3! to increase the rigidity of the construction.

Hub I45 is provided with a radially extending conduit MI by which the fluid passing from conduit 245 through opening I49 may be led to the hose connection I5II and thence into the hose III and nozzle H3.

To provide for automatically returning the hose to stored condition within the housing, the reel is provided with a flange I55 to which is attached one end of a spiral spring I51 as shown at I56. The other end of this spring is hooked over or otherwise fastened to a lug I 59 on a lever IBI which is pivotally mounted on the shaft 245. The lever I6I is provided with a threaded open ing which is adapted to receive a cap screw I53. The capscrew projects through an arcuate slot I65 in the support I3'I' so that the lever may be angularly adjusted with respect to said support. The lever may be provided with a handle I61 to facilitate the adjustment of the spring tension.

The reel is provided with an outer hub III which extends between the flanges I69 at a sumcient distance from the periphery thereof to receive approximately three coils of hose.

One 01 said flanges I99 is provided with a plurality oi openings I12 adapted to receive a cap- 1 screw I19 to hold the switch operating lug or cam 249 on said flange. The various openings I12 are provided so that the angular position oi! the cam may be changed to vary the time at which the switch is operated as will be disclosed below.

The switch 253 may be of any desirable vapor proof or hermetically sealed type. For purposes of illustration, a mercury switch is disclosed in the drawings. This switch comprises an arm 25I which ispivoted at I15 to a flxed portion of the apparatus, which supports at its lower end the mercury tube I11 and at its upper end the operating levers I19 and HI which are pivoted at I99. The pivot I15 is of such nature that the lever 25I will be frictionally maintained in any angular position it may be forced to assume.

The levers I19 and I9I are provided with ears I and I91 respectively, which engage the edges of lever 25I from which the respective levers project. Springs I99 and I99 are respectively anchored at each end upon ears I9I and I93 of the levers and upon the arm 25I so that the ears I95 and I91 are maintained in engagement with the edges 01' lever 25I. Levers I19 and III are of such length that they project into the path of the cam or lug 249.

The overhanging housing 24I is provided with a projecting channel I95 which is adapted to receive all but a portion of the nozzle II2 as the hose is reeled up and stored in the housing. A portion I91 oi the nozzle spout projects beyond the channel to serve as a hand hold whereby the operator may withdraw the hose for dispensing fluid from the apparatus. A stop I99 is provided in the channel in such position that it engages the nozzle guard to prevent further reeling up of the hose when the desired position 01' the nozzle in the channel has been reached.

The opening 241 of the channel I95 is provided with acover 29I which is hinged at 293 in such a manner that the hinge is accessible only from inside of the cover. An outwardly projecting funnel-like passage 291 is provided in said cover to receive and guide the protruding portion of the nozzle. Means are also provided so that the cover may be locked in closed position. This is'preierably accomplished by providing perforated ear 299 on said cover and a similar perilorated ear 299 which is fixed to the housing 2. The ears are so positioned that their perforations will be in alignment when the cover is moved to closed position. By passing the bolt of a padlock 2 I9 through @e perforations, the cover is eflectively locked in place. When the lock is removed. cover 29I will drop to a substantially vertical position to clear the projection I91 of the nozzle.

As shown in Figure 10, the channel I95 merges at its upper end with housing 2 so that no special closure is required other than that just described. An opening in housing 2 connects the housing with the channel to permit the hose to pass from one to the other.

The operation of the device is briefly as follows:

Assuming that the pump has been locked up and that the lug 249 occupies the position shown in Figure 10, the operator will flrst unlock and remove the padlock 21 3 and swing the door or cover 29I to a position in which it will disengage the nozzle spout. By grasping the projecting portion I91 01! the nozzle spout and exerting atension thereon, the operator will withdraw a sumcient amount of hose from the reel 243 to reach to the customer's receptacle. Unreeling oi the hose causes the cam or lug 249 to move in a counterclockwise direction (Figure 10) to engage the arm I19 on switch lever 25I and tilt the mercury switch to the on position. The lug 249 will pass arm I19 as additional hose-is unreeled and as the cam again comes around to the switch operator it will turn the arm I8I, which has been moved into the path of the cam by the actuation of arm I19, about pivot I93 against the action of spring I99 and pass beyond'said arm which moves idly into place under action of the spring I99.

The above described operation of switch 253 causes actuation of the motor 'I I1 which in turn operates pump II5 to draw fluid through suction line I 2I from the reservoir and place'the liquid in the air release H9, meter I23, conduit I25, sight glass I21, conduits I3I and 245, reel conduit I41 and hose III under pressure. The flow of fluid is not accomplished, however, until the operator depresses the nozzle valve, but when this occurs, the flow of fluid causes meter I23 to operate the clock mechanism I33 to register the sale.

As soon as the required amount of fluid has been dispensed, the operator will close the nozzle valve, partially release the tension which up to this time he has been exerting on the hose and the latter will be retrieved under action of the spring I51 which tends to rotate said reel in the hose winding direction. When the nozzle guard engages the stop I99, only the aforesaid portion I 91 of the nozzle spout will remain outside of thechannel or receptacle I95.

As the reel rotates to retrieve the hose, the lug or cam 249 moves in a clockwise direction (Figure 10) It will pass the arm I19 which was moved by the cam out of its path but it will engage the .arm III which is not free to swing idly in the counter-clockwise direction, consequently the switch lever will be rotated until the cam passes over arm I9I and when this occurs the switch I11 will have been moved to circuit breaking position and the motor Ill and pump II5 will have been stopped. If more than one coil of hose has been removed from the reel, the cam will again pass the position of switch arm 25I and will engage the arm I 19 which has been moved into the path of cam I19 by the depression of arm I9I. However, the arm I19 is free to rotate in this direction about pivot I93 against the action of spring I99, hence the cam will pass by the arm I19 without further actuating the switch and when it has passed, the lever I19 will be pivoted in the opposite direction under action of spring I99 to its initial upright position so that it may be engaged and operated by the cam when the latter is again moved in a counterclockwise direction.

Till

iii!

To lock up the pump the operator merely swings the closure MI in a clockwise direction (Figures 10 and 14). The portion I91 of the spout will follow the contour of the closure and project itself through the passage 291. When the perforations in ears 299 and 299 are in alignment the operator inserts the padlock 2I3 and locks it.

It should be noted that the tension on the spring may be adjusted to vary the retrieving force exerted thereby, by loosening screw I 63 and rotating the spring anchor I59 by means of handle I61 in the proper direction and again tightening the screw.

The time of operation of switch 253 may be varied by removing capscrew I13 and lug 249 from position in one of the openings I12 and inserting them in position relative to another 'of said openings. It may be noted that any adjustment of the lug from the position shown in Figure 10, which is just beyond the switch lever in the direction of unreeling rotation, will advance the time of opening of said switch.

It is thought that the invention and its numerous attendant advantages will be understood from the foregoing description, and it is obvious that numerous changes may be made in the form, construction, and arrangement of the several parts without departing from the spirit or scope of the invention or sacrificing any of its attendant advantages.
