This invention relates to liquid dispensing *apparatus of a type adapted for y,dispensing gasoline, oils and the like.
The invention has for one object the provision of improved means for looking up the nozzle of the dispensing hose, when not in use, preferably in a manner such that it not only cannot be used but also so that it is protected from the weather.
rlhe invention also has ior an object the provisionof hose nozzle locking means of a type which will also prevent opening o the valve of the nozzle while the latter is locked Another object of the invention relates to a liquid dispensing apparatus, having a power-operated pumping means withmeans for starting and stopping the same, 'and con- A sists in an arrangement, whereby the hose nozzle when in position for locking prevents access to or operation of said starting and stoppin-g means. I
A further -object of the invention relates to a liquid dispensing apparatus having a plurality of delivery, hoses, all served Jfrom a single power-operated pumping means, and consists in an arrangement, whereby the iiow to any one hose must be stopped before the nozzle Aot that Ihose can be placed in position for locking and whereby the pumping means must be stopped before all the hose nozzles can be placed in position for locking. ,l
I have chosen as an illustrative embodiment of my invention, a so-called meter type dispenser, including an electrically orA other power driven pump which supplies two discharge lines, each including a meter. The invention, however, is capable of use in many other dispensers, which differ widelyv rom that herein shown, and it is therefore not the intention to have the invention restricted to the particular form of dispenser` shown.
Other objects and advantages will appear in the following description and y will be pointed out in the appended claims.
The invention will be disclosed with reference to the accompanying drawings, in which Figs. 1 and 2 are elevational views, taken' at right angles, of a dispensing apparatus em` 1829. Serial K0. 371,255.
4tive positions;
Figs. 5 and 6 are liraentary sectional plan views taken on the les 5--5 .and 6445, respectively of Fig. 3;
Fig. 7 is a fragmentary exterior view shovving the openings in the casing Jor the hose nozzle and the means for supporting the lat# vter in locking position; and
Figs. 8 and 9 are sectional views, taken at right angles, of one of the shut 0E valves used 'in theysupply line to each meter.
' Referring to Figs. 1 and 2, the preferred form ofthe apparatus includes a base 15, a cap 16, and a two-part sheet metal casing 1,7 of modified square cross section (see Fig. 5), which supports the cap from the base. The cap may, if desired, carry a dome 18, illuminated by an electric lamp 19. Located with-v in casing 17, and intermediate the ends thereof, is a horizontally disposed support 20, secured as indicated, to the upper ends of four pipe columns 21, upstanding from base 15. In the space above support 20 is contained a pair of meters and means for controlling the discharge of liquid therethrough. In the space below this support is contained an electrically driven pump for supplyin liquid -to the meters and certain valves an appurtenances as wll appear.
The pump, which may be of any suitable type, is shown at 22 and is sup orted on a bracket 23 fixed to base 15. e electric motor is shown at 24 and is mounted directly on base 15 and connected by a silent chain-25 and suitable sprockets to drive pump 22.
The intake of pump 22 is shown at 26 (Fi 2) and is connected to the branch of a T 2%.
To the lower end of T 27 is connected a suitunderground supply tank. (not shown).
From the outlet of pump 22, a discharge pipe 30, including a T 31, leads vertically upwards and is connected to the lower en d o a cross fitting.32. To thev two klateral branches of the latter are connected discharge pipes 33, which extend vertically upwards through openings in brackets 34 (secured to supportA -F1g. f 5) and terminate with unions 35 for connection one to each of the meters 36.' The T 31 is connected .to a pipe 37 to an air' dome 38. The upper outlet of cross fitting 32 is connected b alpipe 39 to a i relief valve 40, of any suita le typewhich ig'. vi' motor pump an associated `parts,when rewill open when the pressure in pipe 39A exceeds a predetermined value. The outlet of ,valve 40 is connected by a pipe 41 to the u per outlet of the T 27 heretofore desci'i ed.
Thus, a by-pass from the discharge to the suction side of pump 22 is provided', lwhich by-pass is normally closed but'will open automatically to relieve excess?-v either of the discharge lines.
The casing 17.' providedwitlji suitable o enin normally .closed by'doorsf42 and 43 2S?, whereb access may beg/had to the pressure in quire The casing is otherwiseclosed, ex-
c cept for the openings in whichjthe hose nozzlS vare' received, and the normal condition is thatno accesscan behad tothe interior "of the casing except through' such openings. Ther meters 36 ma be of any suita le type. A fwellknownstan ard type is shown conventionall herein and it includes a dial 44 and' ali-iii icator hand 45 associated therewith and movable by and roportionately to, the
volume of the liqui v.passing through its pipe'33. The casing 17 is provided with openings, one adjac'ent'the dial face of each meter 36, to receive short cylindrical sleeves 46 (Fig. 2), which are open at both ends and have lian es 47 at their outer 'ends secured to the casing. The inner end of each sleeve 46 .encompasses and partially overlaps the cylindricalpart of its meter 36, The cap 16 has projecting from the opposite sides, hoods 48 which overlie the sleeves 46 and within each hood an electric lamp 49 is so located as to illuminate the interior of sleeve 46 and the dial face of the adjacent meter 36. The ."several sockets for lamps 49 and lamp 19 are connected bygconduits 50 to a junction box 51, located centrally in cap 16, and from l box 51 a conduit, shown in part at 52, ex-
tends downwardly to the base of casing 17.
wages for these lamps extend through these linner wallof casing i 7 and holds t vand the outlet end of eacha pearing in Fig. 1. To the outlet end of eac hose is secured a valved nozzle 58 of any suitable type. That shown herein is, except forV minor details,
substantiall 'like the `device disclosed inl Eickmann atent No. 1,585,332, dated May 18, 1926, and includes a valve which' is nornially held closed by a sprin but which can v be opened b pushin inwar y on a p unger 59. Ahan lever 601s rovided whic ,when
moved toward the bo y of the nozzle, will open the valve thereof, anda fixed guard 61 is provided to protect the lever from being operated accidentally, i. e.., in case the nozzle is 'oval in form, is arranged to receive the outlet portion of the nozzle while the lower hole 63, rectangular inform, is arran ed to receive the handle60 and guard 61 of t e nozzle. As showi`i, these holes pass through the casing 17 aswell as' through an ornamental plate 64, secured to the casing. One first thrusts the outlet end of nozzle 58 int hole 62 and then swings the nozzle downwardly and inwardly in an arc like path until the guard 61 enters the hole 63. The nozzle, when released, will be supported by the lower part of the ard restin on the lower wall 65 of hole 63. At such time, a lip 66 on guard 61 englages the from swin 'n out of ole 63 unlessfthe nozzle is first raise vsuiiiciently to clear wall 65. In swinging the nozzle into position, the outlet end thereof bears onthe wall of hole 62 and forms a'rough sort of pivot for the swinging movement. Onguard 61 is a perforated ear 67, which when the nozzle is supported on wall 65, overlies a erforated ear 68 formed on plate 64, wherebylli together the nozzle may be locked to the Acasing 17. When in this locking position, the outletend of the nozzle lies within the easing and is protected from the weather. Also, handle 60 is rendered inaccessible, the plate 64'be'ing bent outwardly, as shown at 69 in Fig. 3, in acurve more or less closely cone nozzlev y padlocking these ears l llt forming to the curvature of handle 60, to
prevent one from readily grasping the same. Below'hole 63 is a slot 70 which is of less width than hole 63v and opens at its upper end into the lower end of the hole for a purr pose which will laterappear.
For the purpose of starting and. stopping the pump motor 24, a suitab e switch, such as the push button switchl 71 (Fig. 3) is vprovided. Switch 71, as shown, is mounted in an outlet box 72, which is fixed to a bracket 73 upstanding from member 20 and to which is connected a conduit 74. This conduit extends downwardly in casing 17 towards the base thereof and serves to carry the wires by,
, ing 17 being closed except which switch 71 is connected in the circuit of motor 24. Switch 71 has the usual On and Off push buttons 75 and 76, respectively. When button 75 is pushed upwardly it will close the switch and push button 76 downwardly. The switch is shown in closed position,-button 76 having been pushed upwardly into the illustrated position for the purpose and causing button 75 to move down into the position shown. For the purpose of conveniently operating the button 75 to start the motor, two levers 77 are provided, one'of whichl is pivoted intermediate its ends to bracket 73 and the other to a bracket 78 on member 20. The inner ends of these levers 77 underlie a head 79 on the lower end of the buttonl 75 and the outer ends extend one toward each of the openings 63 in casing 17 terminating in'positions such that an operator can conveniently reach them through the openings 63 when the hose nozzles 68are withdrawn therefrom (see the right hand part of Fig. 4). Springs 80, one for each lever 77, tend to hold the same in the positions illustrated. By depressing either lever, button` 75 will be elevated to close the switch and start the motor. When nozzle 58 is hung up in inactive position, the guard 61 engages the outer end of the adjacent lever 77 and prevents depression ofthe same, as might otherwise be possible by the use of a hooked wire inserted through some one of the openings in -shell 17.
ciently to serve as a support for the hose nozzles 58, wherefore thev latter must be hung up inv the' manner described,-'no other means being provided for this purpose, andthe casfor such openings. The inner and" adjacent ends of the two levers 8 1 are interconnected by a link 84, having trunnions fixed thereto, one near each end thereof, and extending one into a vslot 86 in one of the levers and the other into a similar slot in the other lever. A vertical plunger 55 ,87, disposed in axial alinement with button 6 and underlying the same, vis slidably mounted in a bearing 88, formed on bracket 73. The lower end of plunger 87 is forked to straddle link 84 and is pivotally connected thereto at a point centrally between the ends thereof. A collar 89, fixed'toplunger 87, limits the upward movement of the latter by abutment with bearing 88. The link 84 is show-n in fully raised position in Fig. 3 and when the link is thus positioned, plunger 87 will have been raised high enough to operate button 76 and open switch 71. When the outer ends of both levers 81 lie entirely within the confines of slot 70, the link 84 is positioned as shown in Fig. 3. 81 is raised,as shown in the right hand part of Fig. 4, the outer end of the lever will ex- Ivtend above the lower wall of hole 63 and block the insertion of the hose nozzle therein. The lever mustirst be moved downwardly into the position shown'in the left hand part of Fig. 4 before the hose nozzle is inserted in hole 63. When one lever 81 is up and the other down, as shown in Fig. 4, the link 84 assumes an intermediate position in which its upper end has not been raised high enough When either lever lto operate button 75. When both levers are the casing of which is designated 90. As
.shown in Figs. 9 and 10, a valve 87 is vertically slidable to and from a seat 92, being guided by its stem 93 which slides in a bearing formed in a spider 94. Fixed to and depending from valve 91 is a yoke 95, slotted at 96 to permit it to slide up and down relatively to an operating shaft 97 which is ro-' tatably mounted in casing 90and has one end extending out of the latter through the stuifing box shown. Fixed to shaft 97 is an eccentric 98, adapted when turned clockwise,-
as viewed in Fig-i9, to enga-ge a flange 99 on member and raise the valve 91 to its seat. When turned counterclockwise, eccentric 98 will engage a second fiange 100 on member 95 and 'move the valve away from its seat against the pressure of liquid in pipe 33. The ends of flange 100 ride'in grooves 101 (Fig. 8) of casing 90 to prevent turning of the member 95. yA movement lof shaft 97 through about 45 degrees will open valve 91 suiiciently.
The opening and closing of valves 91 is controlled by the levers 81. Each shaft 97 has a lever 102 fixed thereon and each lever is connected by a link 103 to the inner end of the lever 81 which it underlies. Preferably, the lever '81 has pivotally mounted thereon a block 104 and the link 103 slides through and projects above this block. A spring 105 encompasses the upper end of ea-c'hlink and acts between the block 104 and a washer 106 which is held in'place by a cotter pin 107. The arrangement is such as to permit some travel of lever 81 after valve 91 has been drawn to its seat, the excess travel being permitted by the spring 105, which then compresses. Before either one of the hose nozzles 58 can bc hung up in locking position, its lever 81 must be moved to close that valve 91 which controls the flow of liquid to the noz-l zle thus hung up. lVhen the nozzle isi-emoved from its support, the lever 81 may be overbalanced sov as to tiltup automatically into the position shown in the right hand part of Fig. 4 and open the valve. Sometimes, however, such automaticl opening of the valve is not desired and in such case thedever is arranged so that it must be manually lifted into the described position.
The dispensing system is normally a closed one vsince the valves of the hose nozzles 58 and valves 91 are closed, when the apparatus is not in use. All pipes are filled with liquid as is also each fiexible hose 54. On this account it is necessary to provide relief for possible expansion of the liquid in the closed system. Normally,the air dome 38 suiiciently-serves the purpose but when shuto'l" valves, such as 91, are required to be interposcd in the discharge line, as shown, that part of the system above the shut olf valves .has no means for relieving expansion. To
provide such relief, there is provided in the casing 90 of valve 91, a by-pass 108 around such valve. This by-pass is controlled, and normally closed, by a spring-pressed ball valve 109. On expansion of liquid in the upper part of the system, valve 109 will open to allow liquid to pass into the lower portion of the system, which includes the air dome.
In operation, one or both of the nozzles 58 are removedv from their supports in casing 17, as required. The removal of either one of the nozzles uncovers the opening 63, through which access may bev had to the finger piece of one bf the levers 77. Such finger piece is depressed manually and thel depression of either one will raise button 75 and close switch 713, whereby motor 24 is started and pump 22 operated. In case one nozzle only is removed, the raising of button will lower button- 76 which will depress plunger 87 and link 84 and thereby move one lever 81 in a direction such :as to open the valve 91 to which this lever is connected, in case' the lever has not already been so moved. Usually, it isarranged sothat the lever 81 has to bemanually raised in order to open itsva'lve 91 against the pressure of the pumped liquid, although ashereto- 'fore described,'the lever is sometimesyoverbalanced sufficiently so that it will swing and Aopen its valve 91 as soon asv nozzle 58 is removed. Having started the pump and opened one or both of the valves 91, accordingly as one or both of the nozzles 58 are to be used, such nozzle or nozzles are inserted V.in the illing opening orv openings or the tank or Atanks to be filled. The operator then opens the valve of each nozzle by pressing on the lever 60. The meter or meters 36 regis- -has been dispensed the nozzle 58 is hung up las described. This necessitates moving lever 81 and the resulty will be a closing of that valve 91 which Controls the iow to the nozzle thus hung up. The hanging up of one nozzle will not raise link 84 far enough to operate button 76 and open switch 71 but the hanging up of both nozzles will raise link 74 sufficiently to effect this result, thus stopping the operation of the pump.
lVhen the'apparatus is to be locked up, as atnight, it is simply necessary to padlock the nozzles to their supports. This cannot be done until each nozzle is properly placed on its support and the nozzles cannot be so placed without first moving levers 81 out `of obstructing relation with respect to opening When the nozzles are so placed, the following results are effected z-(l) the discharge end of each nozzle lies inside casing 17 and is protected against the weather, (2) opera- -tion of valve levers 60 is prevented, (3) access to the inger pieces of levers 77 for operating switch 71 is prevented, and (4) the valves 91 are closed.
The arrangement, by which the hanging up of all the nozzles 58'forces the operator to stop the pump, while the hanging up of v less than the whole number of nozzles does not, is important as a convenience and as avoiding needless consumption of power by motor 24. As soonas operation of the motor is no longer required, it must be shut off before the operator can hang up the'nozzles as he should. No other means are provided for supporting the nozzles when not in use, and thus the operator vis practically forced to use the one means supplied `and operate lever 81 as intended.
ln the e-ent that the dispenser includes only one hose, the lever 81, when moved to enable the hanging up of the nozzle of that hose, will be made to open the switch 71. The apparatus, as shown, will so` function for, if one of the levers 81 is permanentl held down as in the position shown in the le t hand part of Fig. 4, the other lever 81 when moved down-will open switch 71.
