Bowser 8; Company, Inc., Fort Wayne, Ind., a corporation of Indiana Application vAugust 27, 1928. Serial No. 302,292 44 Claims. (01. 221-95) One of the objects of my invention is to provide a dispensing mechanism for gasoline and other liquids providing a simple type of construction for supporting the hose nozzle when not in use in such a way that the pump-operating means will necessarily be in inoperative'position, the nozzle will be securely locked stationarily with respect to the housing, and it will not be possible to operate the valve-operating member 10 for the valve of the nozzle. Y

Yet another object of my invention resides in providing a manually shiftable nozzle-supporting -member and combined pump control for a gasoline or other liquid dispensing apparatus which support permanently projects outside of the housing and is constructed and arranged so that when manually shifted to a position such that the pump is in inoperative condition, the support can receive the nozzle for the hose, but

0 when the support is shifted to a position in which the pump is in operation, the hose nozzle cannot be supported on the support, thus requiring first the manual shifting of the support to a pumpinoperative position before the pump can be placed or supported thereon.

Yet another object of my invention resides in providing a liquid dispensing apparatus with a plurality of delivery hoses all served from a single power operated pumping means including instrumentalities whereby pumping means will be automatically stopped only'when all .of the hose nozzles are supported in inactive position.

' Yet another object of my invention resides in providing a liquid dispensing apparatus with a plurality of delivery hoses all served from a single power operated pumping means and wherein each hose is provided with its individual support for the .hose when not in use, and

' their respective pump-ofi position.

An auxiliary feature of my invention resides in the fact of a further construction as set forth in the preceding paragraph wherein the.

hose nozzles can be supported on the hose supports only when the pump controls are shifted to pump-inoperative position.

Yet another objectof my invention resides in the provision of a liquid dispensing device having a specific type of interlocking mechanism operation of the pump, and in which position'the 0 manually operable means for controlling the nozzle valve are inaccessible from the outside of the housing.

Other objects of the invention will appear hereinafter, the novelfeatures and combinations v being set forth in the appended claims.

Fig. 10 shows the position of the locking plates after being moved together;

Fig. 11 is an elevational view showing the locking mechanism in the position which it as- 105 sumes when the hose nozzle is locked in the housing.

In its broad aspects, my invention consists in providing agasoline or other liquid dispensing apparatus which has a pump for forcing no the liquid through the usual meter in the housing, and thence through a flexible hose disposed outside of the housing, and which ter-' is inoperative, and

3. Preventing the operation of the nozzle valve operating member.

In its narrower aspects my invention includes the provision of alternately usable hose nozzle supports for supporting the hose nozzle when not in use, the first comprising a manually shiftable hose support which is also a 'pump-controlling member, and the second, a stationary support for the hose nozzle. In conjunction with this latter support, I provide instrumentalities for effecting the three-way or triple interlock so that when the nozzle is supported for nonuse, the manually shiftable pump control will be inoperative and it will be impossible to operate the nozzle valve lever. It of course will be apparent that in lieu of using a specific type.

of manually shiftable hose support, alternatively I may use any other approved type in combination'with the alternate stationary hose support.

In addition, my invention includes the provision of a novel arrangement of manually shiftable pum-p control member and combined nozzle support which is arranged so that when the nozzle support is shifted to a position in which the pump is operative, it is impossible to support the nozzle on this nozzle support, and the support must be manually shifted to a position in which the pump is inoperative before the nozzle can be so supported.

In a more specific aspect, my invention includes detailed instrumentalities interconnected between the stationary nozzle support on the housing, a manually shiftable pump control member permanently extending outside of the housing, a pump switch, and, in addition, if desired, a delivery valve for controlling the flow of liquid through the dispensing line in addition to the usual valvecontrolled nozzle, whereby various dispensing operations and locking operations of the apparatus, when not in use, are secured.

In addition, my invention also includes the provision of a dispensing apparatus having a -plurality.'of dispensing nozzles and. a common pumping means, and a plurality of manually shiftable pump controls, and a plurality of nozzle supports, the arrangement being such that the pump cannot be thrown to inoperative or 05 position until all of the manually shiftable members have been thrown to inoperative positions, and alternatively, if desired, in which position the respective nozzles can be placed in nozzle-supporting position, and also accomplishingan interlock to prevent the operation either of the pump controls, the removal of the nozzles, or the operation of the valves of the nozzles.

Referring to Fig. 1 of the drawings, 11 designates the storage tank which is adapted to be buried in the ground and be filled with gasoline through the fill pipe 12. By means of a rotary pump 13 operated by an electric motor 14 the gasoline in the tank 11 may be drawn through the suction pipe 15, through the line valve 16 into the gasoline pipe 17. The line valve 16 is a check-valve which opens toward the pipe 17, but prevents flow from' the pipe 17 back into the suction pipe-15.

meters

31 and 32 through the

vertical pipes

33 and 34 to the sight-

glasses

35 and 36 of the

flexible discharge hoses

37 and 38, each of which is provided with a nozzle at its free end, and one of such nozzles is shown at 39 inserted into the housing 40 and locked therein by the padlock 41.

The dispensing units 23 and 24 are respectively provided with pointer and dial indicating mechanisms 42 and 43 operated by the

meters

31 and 32 with provision for re-setting the pointers to zero after each dispensing operation by means of the re-setting knobs 44 and 45. The faces of the dials and the pointers are spaced from glass windows and illuminated by means of an incandescent lamp which'is electrically connected to a source of supply by wires in the conduits 46 and 47. Fig. 6 shows diagrammatically the supply mains at 48 and the incandescent lamps at 49 and 50 with a twopole switch at 51 for lighting the incandescent lamps for illuminating the pointers and dials independently 01' whether the dispensing units are operating or not.

Each dispensing apparatus is provided with manually shiftable means for controlling the pump 13, and while in the broad aspect of my invention, any type of manually shiftable means may be availed of, in the present instance I have shown each dispensing apparatus with a manually shiftable pump controlled member permanently extending outside of the/housing and shiftable in a vertical plane from a horizontal position which represents pump-inoperative position, to a substantially vertical position (as shown in Fig 3), which represents a situation I in which the pump is in operation. In the presporting the hozzle, and it is therefore necessary to manually shift the support 52 back to substantially horizontal position before the nozzle can be supported thereon.

When either operating lever 52 or 53 is swung upwardly the valve 29 or 30 will be opened and the

electric switch

54 or 55 will be closed.

Theelectric switches

54 and 55 are diagrammatically illustrated in Fig. 8. By means of the threepole switch 56 the supply mains 5'7 may be connected to the motor terminals 58 and to the

switches

54 and 55. The electric motor 14 may be started immediately upon the closure of either of the

electric switches

54 or 55 by the upward movement of the lever 52 or the lever 53.

It will be noted by referring to the wiring diagram of Fig. 6, and by referring to Figs. v1,

2 and 3, that the pump will be started by raising of either of themanually shiftable pump controls 52 or 53, and that if both said controls 52 and 53 are raised, that the pump 13 cannot be stopped, underone aspect of the invention, untill all of the nozzles are replaced on their supports 112. In order to place the nozzles on the supports, it is necessary to shift each control 15 member 52 to non-pump operating position, shown for instance in Fig. 2, which will permit the toe 106 hereinafter described, to bereleased so that the nozzles can then be inserted in the openings 111 hereinafter described, and placed on their supports 112. In other words, as long .as the control members 52 are in raised position shown in Fig. 3, the plates 110 hereinafter described, prevent the nozzles being placed on the supports, and it is only when all of the nozzles have been placed on their respective supports 112 that the pump is in stopped position.

- Each of the dispensing units includes a wet hose in that the nozzle is provided with a valve which is .closed when no dispensing operation is taking place and therefore the hose always remains filled with gasoline. It should be understood, however, that my invention is also applicable to dry hose dispensing units. As shown in Fig. 2, the nozzle 39 is provided with a valve at 59 which is controlled by thelever -60.pivoted at 61 on the handle 62 for carrying the nozzle and the free end of the hose. the operator grasps the handle 62 he may reach with his fingers under the lever 60 and move the latter toward the handle 62 to swing the short arm 63 against the pin 64, thus depressing the latter and opening the valve 59.

In the wet hose system, the upward movement of the lever 52 or the lever 53 and the consequent closure of the electric switch to which such lever is connected will start the electric motor 14 and therefore also the pump 13 and the latter will immediately pump gasoline from the tank 11 to produce liquid pressure in the gasoline line comprising the pipes 18, 19, 20, 2 1, 22,.and the connections to the latter. If at this time the valves at the nozzles are still closed and it is not desired to start the pump or to overheat the motor or injure the latter, the pump should be relieved by means of a by-pass and I have therefore provided a pipe 65 as shown in Fig. 1 with a relief valve 66 which opens from the pipe 18 toward the pipe 65 to permit flow as indicated by the arrow 67.

' The relief valve 66 may be set to operate at a predetermined pressure, for example, fifteen pounds per square inch, so that when the pressure exceeds this amount the gasoline will be pumped through the by-pass and when the pressure does not exceed this amount it will be suflicient to eflfect dispensing of the gasoline when the valves at the nozzles are open. I

An air release may be provided at 68 for 70 eliminating from the gasoline in the pipe 18 any entrapped air so that it will not be passed down through the pipe 19 and through the

meters

31 and 32. Such air release may be of the type shown in the co-pending application of Clement s P. Griflith, Serial No. 302,195, filed August 27,

. to which the top of the air release 68 is con- When 1928, for an improvement in air release mechanism for dispensing apparatus. It is desired to prevent air from passing through the meters as they are intended to operate only when gasoline passes through them. For the purpose of rendering the air release 68 effective it may be provided with valve mechanism which will permit upward flow of the air, but prevent the downward flow of air from the vent pipe 69 nected by the pipe 70. If any gasoline should pass upwardly through the check-valve in the air release 68 it will flow down through the pipe 69 back into the top of the storage tank 11. The pipe 69 serves as a vent pipe for the stor- 'age tank 11 so that as gasoline is withdrawn from the latter, air will enter at the top of the tank through the vent pipe 69. Also, when the tank 11 is filled with gasoline through the fill pipe 12, the air in the upper portion of the tank may flow out through the vent pipe 69.

As shown in Figs. 2 and 3, the lever or pumpcontrolled member 52 is shown pivoted at 72 on a bracket plate 73 secured to the housing 74. On the rear side of the housing 74 is a bracket 10,", plate 75 which is provided with a slide bearing '76 for the vertical rod 7'7. To the inner end of the operating lever 52 is pivoted .at '78 an operating rod or member in the form of a link 79 and the lower end of this link is pivoted 105.

about a shaft pin or other member 80 forming a pivotal axis 80 to the upper end 'of the verticalpush-rod 77. The' lower end of the pushrod 77 is connected to a push-plate 81 which is adapted to slide over the

vertical rod

82 and 110 engage the collar 83 to push the vertical rod 84 downwardly to close the electric switch 54. Fig. 2 shows in dotted lines the open position of the switch, and Fig. 3 shows the closed position thereof. When the lever 52 is pushed upwardr 5 1y to .the position shown in Fig. 3, the electric switch 54 is closed and when the lever 52 is moved down so as to rest against the stop 85 on the bracket plate '73, the switch will be released and the spring 86 will automatically open 0 the switch.

By referring to Figs. 4 and 5, it will be seen that to the lower end of the link '79 is also pivoted a link 8'7 which has a slot 88 in its lower end, as shown in Fig, 2, thereby assuring the 5 proper sequence in the operation of the switch 54' and the valve 29. It will be seen that the push rod 77 may be moved downwardly a predetermined distance before the electric switch' is closed. Therefore simultaneously with the 1 closure of the electric switch 54 the valve 97 will be opened by means of the link 87 moving downwardly the valve operating lever 89. When the valve 29 is opened the gasoline may flow from the strainer 27 throughthe pipe 90 into the valve rod 95 extends into a vertical recess 96 at the 14s center of the valve 9'7. The spring 98 holds the valve 97 against its seat when the push-rod 95 is in its upper position. When the operating lever '89 is swung downwardly, as viewed in Fig. 8, the

crank 93 operates to push the rod 95 down and open the valve 97 against the action of the spring 98, thus opening the inlet port 99 through the valve to the outlet port 100.

The valve stem 92 is provided with a packing 101 with a gland 102 pressed against the pack in the bracket plate 75. As shown in Fig. 4, a

plate 110 is securedat its upper endl to the rock shaft 107.

The plate 110 is mounted immediately back of an openinglll in the housing 74. The lower portion of this opening is circular and the upper portionelongated. A scuff plate 112 is secured to the housing to provide protection for the housing 74 at the lower edge of the opening and a suitable support for the weight of the nozzle 39 and the hose 37. The upper elongated portion of' the opening 111 permits passage of the handle 62 shown in Fig. 2 and the lower circular portion of such opening permits free passage of the nozzle 39, valve 59, and the coupling connections between the hose 37 and the nozzle. It must be obvious that this stationary support for the nozzle, when not in use, (112), may be used as the only nozzle support, if desired, in which event the pump controlled member 114 may be constructed in any desired manner so that it is incapable of supporting the hose, but does function solely as a pump control.

By reason of the plate 110 being immediately back of the opening 111, this plate will be struck by the hose nozzle when inserted into said opening so as to swing the plate 110 to the position shown in full lines in Fig. 2., When the operating lever 52 is in the position shown in Fig. 2, the valve 29 is closed and the switch 54 is open. The roller abutment 105 is then sufficiently elevated to permit the quadrant stop 106 to be swung under such abutment, as shown in Figs.

2 and 5 When, however, the lever 52 is in the position shown in Fig. 3, the valve 29 is open and theelectric switch 54 is closed and then the roller abutment 105 is in such; a low position that the quadrant stop 106 will engage the abutment and prevent the plate 110 from being swung back away from the opening 111. It will thus be seen that the desired interlocking'connections can be effected only when the operating lever 52 is moved down to its horizontal position as shown in Fig. 2. When the valve 29 is closed the switch 54 is open.

'During the day while dispensing operations are being frequently performed for supplying automobile tanks with gasoline, the nozzles at the ends of the flexible hoses may be hung on the operating levers either by inserting the nozzle 39 through the circular holes 113 in the operating levers or by hanging thenozzles on the upper curved portion 114 by means of the hook 115 shown in Fig. 2. Obviously the circular hole .113 maybe omitted if desired. Whenever it is desired to discontinue the operation of any unit, the operating lever may be moved to its horizontal position as shown in Fig. 2 and then the nozzle may be inserted into the housing and when this is done, the plate 110 is swung back and the quadrant stop 106 is moved under the roller abutment 105. It will then be impossible for the operating lever to be moved upwardly, because the roller abutment 105 locks the link 79 against downward movement and in like manner locks the link 87 against downward movement and therefore neither the valve 29 nor the switch 54 can be operated so long as the nozzle remains in the housing. Before any dispensing operation can again be performed the nozzle must be withdrawn from the housing so that the plate 110 will drop by gravity to its position shown in Fig. 3 to withdraw the quadrant stop 106 from under the roller abutment 105, thus again freeing the mechanism for operating the valve 29 and the switch 54.

After the nozzle has been inserted through the opening 111 into the housing to occupy the position shown in Fig. 2, the nozzle may be locked in such position, and likewise the hose 37, by means of the plates 116 and 117 which are pivoted at 118 and are provided with

semicircularrecesses

119 and 120 to fit around the hose 37, these recesses forming such a circular opening when the plates 116 and 117 are brought together to the positions shown in Figs. 10 and 11.

The circular opening between the plates 116 and 117 is smaller than the diameter of the coupling between the hose 37 and the nozzle, thereby holding the plate 110 swung fully back to the position shown in Fig. 2. When the looking plates 116 and 117 are together as shown in Figs. 10 and 11, the padlock 41 may be applied 110 to the

perforated extensions

121 and 122 at the upper-ends of the plates 116 and 117 to lock the latter together.

When the padlock is released and the plates swung to their open position shown in Fig. 9, the

semi-circular recesses

123 and 124 may en gage the stop pin 125 secured to the housing 74.

Obviously those skilled in the art may make various changes in the details and arrangement of parts without departing from the spirit and scope of the invention as defined by the claims hereto appended and I wish therefore not to be restricted to the precise construction herein disclosed.
