5A Claims.

My invention relates in general to fluid dispensing apparatus and has more particular ref- -erence to the type having a delivery pipe or hose adapted to be shifted from a normal inoperative position into various positions in order to dispense the fluid.

The invention contemplates specifically a dispensing device .in which the uid is delivered 4through a controllable device into a flexible delivery hose terminating in a delivery nozzle controlled by a manually operable valve. The controllablezdevice may be a valve through which the fluid is forced under pressure from a remote storage or may be a pump. In any event, it is desirable to deliver the fluid to the'hose under pressure shortly before the nozzle valve is opened to accomplish the delivery of the fluid to the customer. It is not desirable to apply the full operating pressure to the exible delivery hose when idle. y

An important object therefore is to provide a dispensing device including a iiexible dispensing hose having a dispensing nozzle, adapted to be hung on a suitable support when not in use, and normally inactive mechanism for controlling delivery of uid 'to the hose, including means whereby the fluid ,delivering mechanism may be actuated .by the `natural movements of the exible hose in being arranged in position to deliver the fluid and whereby the mechanism may be secured against accidental actuation by the hose as long as the nozzle remains in idle position onnits support. l

Another important object of the invention isto utilize the movement of the hose or delivery pipe to actuate means controlling the flow of iiuid to the delivery pipe and to.` provide.vv additional locking means operative 'in such'a fashion that the-control means is necessarily locked before the delivery pipe can assume th'e inoperative position after a dispensing operation is completed, and remains locked until'released by the removal of the delivery pipe out of the inoperative positionfasapreliminary to the making of a de- .liveryr Y Anotheruobject is to provide means to utilize the -movement of the hose or delivery pipe to actuate means controlling the iiow of iiuid to the delivery' pipe and to provide additional locking means operative in such a fashion that the control means is necessarily locked before the de- "livery vpipe can assumethe inoperative position after `a dispensing operation is completed, and `wherein the control means remains locked until actuating the (Cl. 22o- 95) manually released after the delivery vpipe has been removed from inoperative position.

Another object is to provide a device in which the hose must be moved from inoperative posi-v tion before the dispensing device may be unlocked 5 and conditioned for' operation and wherein the hose thereafter must again be shifted to set the device in operation. Y

Numerous other objects and advantages of the invention will be apparent from. the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment of the invention.

Referring to the drawings:

Figure 1 is a partial perspective view of a l,dispensing device embodyingv my present invention;

Figure 2' is a horizontal section taken substantially along the line 2-2 in Figure 1;

Figures 3 and 4 are sectional views substantially along the line 3-3 in Figure 2;

Figures 5 and 6 are views taken respectively and substantially along the lines 5-5 and 6--6 in Figure 3.

To illustrate my invention,'I have shown on 25 the drawings` a dispensing unit comprising 'a frame forming a casing Il on and in which lare mounted the severall elements of the dispensing apparatus of my present invention. The casing is preferably formed with the conventional .dial having pointers I5 for indicating the quantity of fluid dispensed, it being understood that the casing may contain a suitable meter I1 and fluid flow controlling device, such as a pump I9, whereby fluid to be dispensed may be delivered from a suitable storage (not shown) as by means of a conduit 2l through the control device I3 and thevrmeteivl-l,` whiclris operatively connected for pointers i5. From. the meter, the fluid may be delivered through a see" gauge 23 into the delivery pipe 25, which, in the illus-f trated embodiment, comprises a flexible hose, theA outerend of which is provided with a discharge nozzle 21.- l

The discharge nozzle 21 is preferably provided with a valve vfor controlling the flow of fluid therethrough and has a guard 29 for a handle 3l, which may bemanually operated to control the valve, the valve beingnormally biased toward closedposition and being depressible by means of the handle when it is desired to dispense nuid through the nozzle.v The nozzle also has preferably a flexible delivery tube 33 connected to the discharge side ofthe valve. The casing carries a hook 3 5 stationarily mounted thereon in a convenient position and the hook has a pair of, prongs 31 between which the hose may extend and which provide support for the nozzle when not in use. Suitable means may'also be provided for interlocking the nozzle Aon the hook in such a fashion that accidental movement thereof from inoperative position may be prevented.

The casing also has a receptacle 39 for the reception of the discharge tube 33 when the nozzle is supported on the hook, the receptacle comprising a casing having an opening exposed to the exterior ofthe housing I I and being provided with a lug 42 by which the receptacle may be secured as on a frame member 5I of the housing.

The operation of the iiuid control means I9 is accomplished by movements of the hose 25 at the will of the attendantin arranging the hose in position to accomplish delivery of the fluid being dispensed. 'Ihe hose, near its upper end, is attached to a shaft 4I, which is mounted for rocking movement within a guard 43 carried by the housing. The inner end of the rocking member 4I is connected to one end of a. link45, the other end of which is attached to a lever 41. 'I'he lever 41 is pivoted on a bracket 49, which, in turn, is

' secured to a member 5I forming a part of the frame of the casing. The lever 41 also is pivotally connected with the upper end of a bar 53, the

' lower end of which is arranged to actuate the fluid control device I9.

'Ihe uid control device, as heretofore mentioned, may be a valve forming a part of theV delivery line 2|, but may be a fluid forcing device such as a pump,as shown in the drawings. In either event, the shaft 53 may be connected to actuate the device I9 either directly or indirectly. I prefer, however, to connect the shaft 53 so as to operate a switch 55, which in turn controlsan electrical circuit 51 adapted to energize a motor 59, which is connected to the pump I9 for driving the same when the switch 55 is closed. Of course, any suitable arrangement may be employed for permitting the movement of the bar 4I initiated by movements of the hose 25 under the direction of the attendant 'to'control the operation of the device I9. It will be understood that movements of the hose 25 will cause the shaft 4I to tilt upon the casing and will draw the link 45 outwardly and cause the lever 41 to move in the direction of the indicating arrow in Figure 3 of the drawings to the position shown in Figure 4. Such a tilting movement will draw the shaft 53 upwardly against the urge of a spring 6I, which is connected between the shaft 53 and the frame memberv 5I of the housing to normally urge the parts to a position in which thepump is inoperative. By drawing the shaft 53 upwardly against the spring means 6I, the switch 55 may be closed to complete the circuit 51 and set the motor 59 in operation to drive the pump and 'thus force the iiud through the conduit 2l, the meter I1, the see gauge 23 and the delivery hose 25 to be thence discharged through lthe nozzle 21 under the direct manual control of the attendant.

siderably reduced. I desire, therefore, to provide a. means for ensuring that fluid will not be forced into the vhose under pressure accidentally at such times when the delivery nozzle is hung in inoperative position on the hook 35. It should be understood, of course, that as soon as the delivery operation is terminated by 4the closure of the nozzlevalve, the attendant will release the hose which will naturally gravitate to a position in Y which the shaft 4I is not tilted with respect to the housing and that this will result in the opening of `the, switch. However, movements accidentally ,imparted to the housing may operate the mechanism to close the switch even after the hose nozzle is hung upon its hook and in order to obviate this of the rod 53 and thus lock the rod against upward movement when the lever 65 is in the position shown in Figure.3 of the drawings. 'Ihe portion of the lever 65, which projects out of the casing, is formed as a substantial plate 13 and the lever itself is located adjacent the hook 35 in such a position that the lever 65 is forced to assume the locking position before the nozzle can be hung on its supporting hook and the nozzle itself is formed so that the guard 29 cooperates with the plate 13 to retain the lever in locking position as long as the'nozzle is supported on the hook.

After the nozzle is removed from the hook, the

plate 13 of the lever may be grasped by the operator and drawn down to the position shown in Figure 4, the hook35, being formed with a portion 15V providing a stop for limiting the downward movement of the lever. When in the lowered position, the plate 13 occupies the space above the hook and prevents the replacement of the nozzle thereon without raising the lever 65 to the locking position. When in the lowered position also, the cam portion 69 of the lever re- -leases the bar 53 so that the same can be shifted in-response to the movement of the hose under the control of the attendant in order to actuate the fluid flow controlling device I9 as heretofore described.

It is thought that the invention and numerous of its 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 my invention or sacrificing any of its attendant advantages, the form herein described being a preferred embodiment for the purpose of illustrating my invention.
