(Cl. Z22- 32) 13 Claims. 1

ThisV invention relatesto improvements in fluid measuring and dispensing apparatus and. more particularly, toV such apparatusas is adapted for dispensing measured quantities of gasoline or thev like.

The general object of the invention is to provide in a gasoline dispensing apparatus improvements which simplify the work of the operator and make it easier and more convenient for him to service the fuel tank of an automobile.

According to one object' of the invention, a single control member is provided outside the pump casing mounted for movement back and forth throughout a predetermined range and operable, when moved from one limit to the other ofsuch range, to eilect a complete cycle of movement of the resetting shaft of the register and then to start the pump motor, whereby resetting ofl the register must be effected before pumping' can commence, said member being operable when moved from the last-named to the other limit, to stop the motor without actuating said shaft.

According to another object ofthe invention, the single control member may be part of a swivelled mounting for the delivery hose so that as the hose nozzle is carried to the tank to be serviced, the hose will bepulled to turn the said part of the swivelled mounting and cause resetting. of the register and starting of the pump motor without any special effort or attention on. the part of the operator.

According to another object ofthe invention,

the mounting includes a rigid pipe, having a` vertical portion, rotatably mounted adjacent one side of theA pump casing to turn about its own axis, and a transverse portion, to the outer end of which the hose is connected, this transverse portion being high enough to clear the top of the pump casing, when such portion is turning, andl long enough to extend from one side to the other of the casing, such pipe being turnable' to any desired position through a 360cr range to provide for convenience in servicing and for extension of the servicing range.

The invention has for another object the provision of means, preferably interlocked with the nozzle and nozzle support, for holding said pipe` i in one predetermined angular position, when the hose is not in use', such position being one wherein the transverse portion of the rotatable pipe overlies the top of the casing.

The invention has for another object the provision of actuating connections between the rotatable pipe and the register of the apparatus for resettingV the latter by the movement of the rotatable pipe through a predetermined' angle from a predetermined initial radial position, and preferably irrespective of the direction in which the rotatable pipe turns.

These and other objects will' best be understood from the detailed description of the examples of the invention with reference to the accompanying drawings, in which:

Referring to these drawings and first to Figs. 1 and 2 thereof, the invention is shown, by way of illustrative example, asA embodied in a gasoline dispensing apparatus of well known form. Such apparatus includes a pump I, driven by an electric motor 2, through the belt 3 and pulleys 4 and 5, and adapted to draw up fluid such as gasoline, from an underground supply tank (not shown) through a suction pipe 5 and force it outwardly through a delivery conduit, which includes a flexible hose "l, having on its outlet end a valved hose nozzle 8. As shown herein, this delivery conduit includes a pipe 8' connecting the outlet of pump I to an air separator 9, a pipe I9 connecting the outlet of separator 9 to the inlet of Va meter Il and a pipe I2 connecting the outlet of the meter, by means later to be described in detail, to a swivelled pipe I3 to the outer end of which hose 'I is connected by means of a suitable coupling I4. Interposed in pipe I3 at its highest po-int, is a visible discharge indicator I5 of any suitable or desired form. v

The meter II, which measures the fluid dispensed, drives through a shaft I5, a register`I, which indicates the amount of iiuid dispensed in quantity, cost or both. As shown, the register is of the well known computing type and has number Wheels i8, visible through openings I9 in a dial plate for showing the quantity of fluid dispensed, in gallons and fractions thereof, and other number wheels 2l visible through openings 22 in said plate for sho-wing the cost of the fluid dispensed, in dollars and cents. The register may, for example, be of any suitable type, such as the well known Veeder-Root type or the type shown in the DeLancey Patent No. 2,390,239, granted December 4, 1945,

The apparatus described, except for the hose 1, and pipe I3, is enclosed in a suitable upright casing and supported from a suitable frame located within the casing in any suitable way. As herein shown, the frame includes a base 23, angle iron columns 24 iixed to and upstanding from the .base and an inner cap 23, which ties together the upper ends of 'the four columns. The casing has a cap 23, supported by the inner cap 25, and front, back and side panels ZTI, 23 and 29, respectively, which enclose the space between the base 23 and cap 23. The columns 24 carry platforms 33 and 3l, the former supporting the motor 2 and pump I and the latter the register I'I.

The swinging pipe arm i3 is mounted, as best shown in Figs. 3 and d. Extending across between a pair of the columns 24 and secured at its ends thereto is a plate 32. Bolted to this plate is a casting 33, which extends outwardly through an opening 34 in the adjacent side panel 29. This casting has mounted therein axially-spaced upper and lower bearings 35 and 33, which rotatably support the vertical portion of pipe I3. The casting 33 has on its upper face a race for a plurality of balls 37, upon which rest a disk 33, xcd to the pipe I3. The said upper face, the disk and the balls serve as a thrust bearing to support the pipe I3. This `pipe is held against upward displacement by a collar fixed to its lower end and engaging the lower end face of bearing 36. Thelower end of pipe I3 is open and in constant about twice the length of the pipe.

communication with a chamber 49, formed in a casting 4I, xed to the lower face of casting 33 and closing the chamber 43. The only other communication with chamber 49 is by way of the described pipe I2. rihe metered uid from pipe I2 thus flows throughchamber 40, and pipe I3 to hose l. Leakage from chamber 40 is prevented Iby two seal rings 42, which are mounted on pipe I3 between the bearings 35 and 36 and forced apart by a spring 43 and thereby pressed, one against the upper face of bearing 33 and the other against the lower face of bearing 35. The casting 33 is preferably enclosed by a casing 44, suitably fixed to side panel 29. Casing 44 has in its upper Vend a circular opening bounded by an upstanding annular rim 43. Fixed to pipe I3 is a circular cap 46 which overlies the opening and has a downturned annular rim 4? overlapping the rim 45.

When the apparatus is not being used, the pipe I3 overlies the cap 26 of the pump casing, extend-- ing from oneside to the other thereof, and the hose is then disposed in a long loop, extending downwardly from the outer or free end of pipeV I3 toward the bottom of the pump casing and then upwardly toward the top or" the casing, where the nozzle 'I rests on a suitable sup-port, such as 43. The spout of the nozzle usually lies in a boot 49 to protect it from the weather and, when so located, a portion of the guard 50 for the valve lever 5I of the nozzle rests on the support'. As best shown in Fig. 3, the guard lhas an opening therethrough to receive an upstandingear 52 on the nozzle support 48. The ear is perforated to receive a padlock to enable the nozzle to be locked to the support. When the apparatus is used for dispensing, the nozzle is Vremoved from its supn port and carried to the tank to be serviced. In so doing, the pipe I3 will be swung to 4one side or the other of its normal or neutral position and it maybe swung through varying angles to extend the service range. The pipe I3, when turned degrees from neutral position, effects the maximum increase in the service range, which is t may be turned to a lesser extent, according to requirements, but it will always be turned at least 45 degrees from neutral position for any servicing. Of course, the pipe can turn 360 degrees, if necessary or desired.

To assist the operator in locating pipe I3 in various positions, recesses such as 53 may be provided in the periphery of disk 38 and a springN pressed detent 54 mounted on casting 33' in position to engage in any of the recesses as the disk is turned. As shown one notch is located so as to be engaged by the detent, when pipe I3 is in neutral position, and the other notches are spaced at 45 degree intervals therefrom.

Aside from the advantage of increasing the servicing range of the pump, the swivelled pipe I3 may be utilized as a control member, operable by its movement to eiect resetting of the register I'I and then the starting of the pump motor 2, and subsequently operable to eiect stopping of the motor. For this purpose, an actuating cam is provided, fixed to pipe I3. In this case, a cam path 55 is formed in the upper face of the described disk 38 to receive a roll 55 mounted on a lever 5l, which is pivoted at one end on a stud 58 fixed to an upstanding hub on casting 33. The cam path 55 is constructed so that when pipe I3 is turned through a predeterminedV angle. say for example 30 degrees, in either direction from its neutral position, the lever 5l will be 5,; movedv its;` full stroke (to.- the left as shown in- Fig.` 4f. Further rotation of the pipe causes ther roll; 56: to engage in a dwell; portionof thecam, whereby the pipeV t3` canthus` turnwwithout moving; the lever; .When the pipe is turned back toits neutral` position, the lever 5T will be moved back` during the last degree part of its move-` ment, into the` position-` illustrated. ThisV lever is arranged by any suitable transmission' to operate a. mechanism to reset the register and to actuate the switch of the pumpfrnotor' 2. herein, such transmission consists of a. Bowden wire. 59,. one end of which is. connected to lever 5T, and a. sheath: 59?' for theV wire, one end of which sheath is held' by a suitable anchor 6I to plate 3'2; or any other: stationary part of thea apparatus. The Bowden wire and its sheath extend across the pump casing over the top7 of register l1 and thendownwardly tothe mechanism` for resetting: the` register, later to be described.

In one form of register, there is a shaft 52', which, when turned through a predetermined angular extent, in this case 405 degrees, in one direction (clockwise as viewed in Fie 8) will reset the number wheels to zero. This shaft will then be. turned back, by means within the register, through an angle of degrees, making the net movement of shaft 62, 360 degrees or oneV revolution. As shown in Fig. 8, the shaft 62 has fixed; thereon a ratchet 63 and a disk 64, having a single radial notch 65 in its periphery. A spring-pressed pawl 56 cooperates with ratchet 63 and is normally engaged with ratchet tooth 67'. 69? of the register and carries near its lower end a roll Hl adapted to engage in notch 65.. A spring 'l-I., connecting member 6-8 tosome stationary part of the registerl tends to turn member 68V clockwiseand through roll 1G. to turn disk 64 counter:- clockwise but is unable to do so on account or the engagement of p-awl 66 with` ratchet tooth 61. rotating reversely fromV the position shown. To reset the register, shaft 62 is turned clockwise. As-it is thus turned therst action is to movey roll 10.- to the right and stress spring 1l.. r[his action continues for 45 degrees, when roll. 1d' will'. ride out of notch y and onto the periphery of disk 64, where it will not exert any force:4 on the disk tending to turn it backward'. During this Li5 degree interval, the usual clutches (not shown) will be actuated to disconnect each set of number Wheels from the meter driving mechanism andthen connect them to the resetting shaft 62,A all as. disclosed in the aforesaid patent. The rst tooth12 of. ratchet 63 has. an angular extent of slightly more than 45 degrees. One canA therefore. turn shaft 62 through the initial4 45` degree movement and then move it backward to its nor`- mal. and illustrated position. However, after resetting has commenced, which occurs just after the initial 45 degree movement of shaft 82 is comU pleted, the latter cannot be restoredl to its initial position. by reverse rotation because of pawl 6 and ratchet 63. Shaft 62 can thenl be turnedonly in a forwardly or clockwise direction.. Thus, resetting, once initiated, must be completed. After the shaft 62 has been turnedV 465 degrees, the disk164 will move under roll lil and the latter will. drop into the notch 65. Then, spring 15|, acting through member 68. and roll: lo will turn disk 6.4 backwardly (counterclockwise)`y into the position shown, the long tooth 'l2 permitting this reverse movement;

As illustrated A member 6B is mounted to swing on a shaft The resetting shaft 62 is thus held from Resetting will have been 6, completed prior to this reverse movement". of shaft: 62- and during suchl reverse movement, the` clutchesl of the `register will be: actuated to disY connect the number wheels from shaft 6-2 .and reconnect them to the driving mechanism. actutated by meter shaft I6.

Not all forms of registers employ reverse move--v ment` of thev resetting `shaft after the endl of the resetting movement but. those that do employ` such reverse movement, present specialdifli'culties` in adapting this invention for' use with them, and they will be considered' first, bearing in mind. that there. are other forms of registers, wherein` a. predetermined movement of the resetting. shafts in one* direction only willeffect resetting.

The reset shaft6-2 `(Fig. 3)' extendsfoutsidethe` casing of register |1- and has fixed to itsA outer end a socket member 13) which is connected by meansv of a shaft 'I4 to` a socket member 15,. fixed on the inner end of a. short shaft 16which isratatably mounted in a hub ofV a plate 111 and which has fixed to its other end` a pinion` T8..

The pinion is the terminal. element of the re setting gearing, which isactuated bythe ahove= described Bowden wire 59. The plate lliislxed at itsl ends, one to each of two of the columni` 24, and supports such gearing.. The i. shaft` 1&1 connects the two socket members 13 and 15 and` allows one to be driven from the other even if' the two sockets are' not exactly aligned. Each socket member hasV a cylindrical socket toy receive aball 19 on theend of' shaft 'M The peripheralwall of each socket has two. diametrically-opp' site longitudinally-disposed slots therein, to slidably receive the projecting ends of ai cross pin 8l, fixed in` ball` 19 and extendingdiametrically therethrough. i

The reset gearing includes a gear 82,.which isr teeth. This arm 84 is connected to the lower endv` of the described Bowden Wire 59', Vthe sheath" 60 of which is anchored alt-60 to plate T1.

Thus, swinging of the pipe I3 will oscillate the pawl' arm. In this particular case, the cam isconstructed to swing pawl 84` through l-4 of'a revolution. The ratio of gear 82 to. pinion T8, in this case, is 8 to 1, the gear 82 having 64 teeth for ex'- ample, and the pinion 181 having 8 teeth. The pawll 84 initially abuts one ratchet tooth as shown. when pipe I3 is in its' neutral position;

When arm I3 is moved in either direction from. neutral position, through an angle ofA say' 30 degrees, the pawl 84 will swing upwardly 9/4 of' a. revolution and turn gear 82 counterclockwise. by the same amount, or nine teeth. This will drive pinion I8 clockwiseA nine teeth or one and one eighth revolutions and shaft 62 will thus be turned the required amount to complete resetting of register I1. Fixed to plate 11' is a` cam 88,. arranged in the path ofi pawl 8`4` and adaptedr when the latter' reaches the end of its upward stroke, to release the pawl 84 from the. tooth, 4

which itv had theretofore been driving. On such release of the pawl, the spring Tl; of the register will very rapidly turn the reset shaft G2 backwardly (counterclockwise) by an angle of` 45 de.-

grecs. This will turn pinion. 18. one. tooth. inA a coimterclockwise` direction, whereby' gear 82 'will be turned one tooth in'V a clockwise direction, bringing it beneath pawl 84 so that the latter, when subsequently released from the cam 88 during the initial part of its return or downward movement cannot become drivingly engaged with such tooth. The pawl 84 will be swung downwardly just far enough to engage beneath the next ratchet tooth of the series in position for a subsequent resetting operation in the manner described.

The switch for stopping and starting the pump motor 2 is contained within the casing of the motor and is usually of the toggle type. This switch is operated by pulling or pushing on a Bowden wire, contained within a sheath 90 which, as shown in Fig. l, extends upwardly in the pump casing. The upper end of this sheath is shown in Fig. 5, fixed by an anchor 9| to a plate 92, which in turn is xed at its ends to two of the angle iron columns 24. The upper end of Bowden wire 93 is shown as fixed to a lever 95. Lever 94 is pivotally supported intermediate its ends on a stud 95, xed to plate 92, and has at one end a roll 96, pressed against the periphery of a cam 91 by means of a spring 98, which connects the lever to plate 92. The cam 91 is mounted to turn on a stud 99, fixed to plate 92, and is turned by means of a link |09, which connects it to pawl 84. The cam 91 has a dwell surface on which roll 96 rides, until the pawl 84 reaches the end of its upward stroke, when the roll rides off this dwell surface onto a steep drop |02. The spring 98 would move roll 9B quickly to the bottom of this drop |92, except for a dashpot |03, the piston I 94 of which is connected by its rod 05 to lever 94. The descent of piston |04 is limited by the small area of the vent |06 of the dashpot, whereby the closing of the motor switch is delayed and made to occur after the pawl 84 has reset the register. The switch, being of the toggle type is not actuated until at the very end of the stroke of lever 94.

The cam 91, lever 94, spring 98 and dashpot |03 provide for a time delay between the actuation of the register-resetting means and the closing of the motor switch. This time delay, while desirable as insurance that the motor switch cannot be closed until resetting of the register has been completed, may not in all cases be necessary. As will later appear, the Bowden wire 93 may be connected to the pawl 84 without the intermediary of the time delay device described. Ordinarily, if the motor switch is closed at the same time that the gear 82 has completed its resetting movement, the 45 degree reverse movement of the register shaft 62 will be effected almost instantaneously by spring 'II and before the operator will have time to open the valve of the hose nozzle and thereby cause movement of shaft I6 and the number wheels of the register I'|.

The shaft 99, to one end of which cam 91, is fixed, is mounted in a bearing |01, xed to the outer face of plate 92 and extending through and beyond the adjacent side panel 29. On the outer and upper part of the bearing is mounted the nozzle support 48, heretofore described. Such support is pivoted to the bearing at |08 and is'urged upwardly by a spring |09. When the spout of nozzle 8 is placed in boot 49, the lower and horizontal part of the guard 50 of nozzle 8 is swung inwardly and deposited on the pivoted support 48, whereupon the latter moves downwardly under the weight of the nozzle into the position shown, in which the outer end of sup- 8 port 48 lies in a recess in a collar |I0, fixed to the outer end of shaft 99. When the switch of motor 2 is open and the parts of the resetting gearing are positioned as shown, the recess in collar |I0 is positioned so as to receive the hose support 48. When collar I0 is in any other position, as it is when the motor switch is closed and pipe I3 swung out of its normal rest position, the support 48 rides on the periphery of collar IIB and the nozzle 8 cannot thenv be hung up. Thus the operator must restore pipe I3 to its normal or neutral position before he can hang up the hose nozzle. When the nozzle is hung up, as described, its interlock with collar ||0 prevents the pump from being started, the resetting means from being actuated and the pipe I3 from being swung away from neutral position.

If desired, an interlock collar III, such as shown in Fig. 10, may have a recess wide enough to directly receive the guard 50 of the hose nozzle 8. In this case, the bearing |01 would then serve as a stationary hose support and the pivoted member 43 and its spring |09 can be elim inated.

In operation, the operator must iirst remove the nozzle 8 from its support 48 or |01, as the case may be, before he can swing pipe I3 by pulling on the hose. The interlockv between the nozzle and collar II or III, as the case may be, locks pipe I3 in its neutral position against rotation and hence prevents the operator from starting the pump motor. Having removed the nozzle 8 from its support, the operator carries it to the tank to be serviced and, in so doing, swings pipe i3 away from'its neutral position. Ordinarily, in moving the nozzle to the tank to be serviced, the pipe I3 will be swung far enough to actuate the resetting gearing, as described'and then close the motor switch, all without any eiort or attention on the part of the operator. However, if the pump doesnt start, the operator will have to pull on the hose to swing pipe |3 far enough to effect the resetting of the register and the closing of the motor switch. The swinging pipe enables extension of the service range, whenever required, and enables easy servicing of cars on either side of the island, on which'the pump is ordinarily mounted. The pump control and the register resetting occur automatically by the pulling of the hose necessary to carry the nozzle into servicing position.

For use where hose extension by means of a swinging pipe is not needed or desired, the pump shown in Figs. 11 to 15 is provided. This pump is constructed like the one, above described, except that the swinging pipe I3 and associated devices are omitted and the delivery hose emerges from the opening near the top of one of the side panels 29, the hose being suitably connected inside the pump casing with p-ipe I2. Suitable visible discharge indicators I|2 are also provided in the delivery conduit and extend through the front and back panels 2l and 28 of the pump casing, as indicated in Fig. 11. The hose nozzle 8, when its spout is inserted in boot 49, is supported by the horizontal portion of its guard 59 resting on `top of a fixed support H3, which is fastened at its inner end to plate S2 and extends outwardly through the side panel 29. Near the outer end of support ||3 is an upstanding ear |I4, which passes through a slot in guard 50 and is perforated to receive a padlock, whereby the nozzle may be locked t@ its support.

The resetting gearingis the same as heretofore described but the control member, which actuates it, consists of a 'small handle |45 instead of the swinging pipe I3. This handle is xed to the outer end of a shaft |16, which is rotatably mounted in support |13 and has xed to its inner` end a lever |11. The outer end of this lever is connected by a link 2|,I8 Ito the pawl 84 which actuates the resetting gearing. The Bowden wire S3, which actuates the switch of the pump motor, is also connected toolever ||1 by means of a suitable connecting piece H9. On the inner end face of the hub of Yhandle ||5 is formed a lug |20, having radial sides adapted to abut one .or the other `of two radial stop faces |2| and |22, formed on the nozzle support H3. These stops `|21 and 4.22 Alimit the extent of swinging movement of handle ||`5 to .exactly that necessary to swing pawl 8.4 through an angle equal to 4that .between `successive ratchet teeth and to thatnecessary to move the motor switch between its on and off positions. When ,handle ||5 is positioned, as .shown in Figs. 12 and 13, so that its lug |20 abuts stop |21, the pawl84 is in its extreme lower position and the motor switch is open. Clockraised far enough to .actuate the resetting .gearl ing, in the same manner as heretofore `described, and also move the motorswitch to fon position. When .dispensing .is finished, the operator must swing handle |I5 .counterclockwise until the lug abuts stop |2.| in order to hang up the .nozzle on its support and, in so doing, the motor switch iis `moved to 4oiF position Vand the pawl84 is restored to its lower position inreadiness 'for a subsequent actuation .to reset `the register. y

Another form of `thein-v-entionisillustrated in Figs. 16 to 19. In this,-as well-as in the iirstform of the invention, the `control member lis the swinging pipe l|3 and it is-mounted-andioperates in the same way as described in `connection with Ngs. .1 to `5. The `casing x44 and cap 145 will be used but these have 4been omitted yin Fig. 17. However, in .addition vto cam 155, `which ractuates lthejBowden Vwire 59, a separate `path cam |24 is 4provided in a .disk .125, ,fixed .to pipe 1.3, :for :the purpose of actuating- `the `motor switch and Aa clutch, to `be .later described, in `the :resetting gearing. .A .roll |,2\3,1mounted on and depending .from 4a lever |21, rides `inl-cam 424. 'Lever 121 is pivoted at one `end on .a stud |28, `fixed Lto member :33 and has attached to its other end lone end of .a Bowden wire :1:29. The sheath |38 for this Awire 4is anchored fat its upper end, `togather withgthe upper end of sheath .60, by means .of a clamp 13|, which `binds itt to a bracket |321Xed .to plate .32.. Theilowerend of sheath is fixed by :an Aanchor 433 .to plate 111. "The lowerendofthe `Bowden .wire |29 is iixedto the outer end :of a horizontal arm |534, `nxed .at its innerend to one endof a 'shaft `1.3.5. Also :fixed to .shaft .ladjacentarm 314 is La clutch-shifting fork |35. `The shaft |35 is `rotatably mounted in a bearing |31, xed to plate 11-1, .and ,is held in axial :position :by Ithe engagement .of 'the Snub of fork :|36 .and la collar 1138, which is dxed `to the shaft, with opposite end faces of the bearing |31. The fork |36 has trunnions engagedin a circumferential groove |33 in a clutch element |40. This element is axiallyslidable on a shaft |4I, which is rotatably mounted in a bearingon plate 11. Shaft |4| has xed to its outer end a pinion `|42 and to its inner end a clutch element |43. The members |42 and V|43 abut opposite sides of the bearing for shaft 14| and serve `to retain the shaft in proper axial position. vThe outer end face of element 14d and the inner end face of element 4|43 `have teeth suchas |44, which are normally `held .engaged but maybe disengaged by axial movement of element .|45 to the left by means of the clutch fork |35, actuated .by Bowden wire |29. This clutch element |43 'has on its inner face a socket |45, similar to the heretofore described socket 13 on the reset shaft 162 of register I1 and connected to socket 13 by a shaft |46, which has ball ends to fit in .the `sockets and cross pins in the Vball ends .to fit in Aslots in the .side walls `of the sockets in the same manner as'heretofore described in connec `tion with shaft 14. A spring |41, coiled around `shaft |46, vacts :between two washers |48 on the shaft |46 to pressagainst the .end faces of .sockets .13 and |45 and press the clutch element |40 -toward and into engagement with its cooperating element 143.

The arm |34 `is connected by alink 1h19 to Lthe `upper end of a connector strip |511, `the lower lend Iof which is attached to `the Bowden wire :93, `which .actuates the motor switch. The strip 1.5i! .is pivotally connected at a point intermediate Vits ends to oneend of an arm I5|, the other end of which .is fixed to the inner end of the shaft :99, in place of the cam 91, heretofore described. This shaft 99 is mounted, ras before, and carries on its outer end a collar, such as 0, for interlocking with the hose nozzle support, as heretofore described.

The Bowden Wire 59, actuated `by cam 55,

serves, as in the rst form of the invention, to

oscillate .a pawl. This pawl, marked |52, is mounted in the same way as `pawl S4, and Vis engageable with ratchet teeth |53 xed to a gear |54, which is rotatably supported from plate 11 in the same way as gear 82. Gear |54 meshes with pinion |42. The ratio of gear |54 to pinion |42 '9.to 1. lIhe ratchet teeth |53 are spaced 45 degrees. The cam 55 is arranged to move pawl .|52 45degrees. Thus, the gear I 54 will be turned one eighth of a revolution on Veach upward stroke of pawl :|52 and will thus turn pinion |42, one and one eighth revolutions, which is what is `required to reset the register I1. The cam |124 is'designed not to move lever `|21 until aftercam 55 has moved pawl |52 through its complete upward stroke. Then cam VI 24 acts to move Bowden wire :|29 far enough to cause clutch elements |40 and `|43 to disengage and Ato cause the motor switch -to move from off `toon position. Actually, `the clutch element |43 lmoves beyond the position where its teeth disengage from the teeth onelement .143. `On -disengagement of the `clutch elements, the reset shaft .E2 of the lregister will move `backvvardly 45 degrees and come to rest. This occurs lbefore the end of `the stroke of arm |34, While the motor switch `is not moved to on position until the `very end `of `the stroke. Thus, the switch cannot `be closed until after the resetting `shaft `62 comes to rest. The teeth ofthe clutch elements are spaced ll5 degrees, so that when .the clutch elements arersubsequently-moved into engagement, there will be no lost Amotion between them. Thus, on a subsequent clockwise movement of pinion |42, the clutch element |43 will immediately pick up and move clutch element |40 so that reset shaft will again be turned the required amount, in this case one and one eighth revolutions.

If desired, the time delay means shown in the first form lof the invention may be used, the cam 91 being xed to shaft 99 in place of lever I5i and the Bowden wire 93 being actuated fro-m the cam through a lever which is pulled by a spring against the resistance of a dash pot.

In operation, when the operator wishes to service a car, he removes nozzle 8 from its support and the latter disengages from the notch in collar III] and allows the pipe I3 to turn. In carrying the nozzle 8 to the tank of the car to be serviced, the pull on hose 1 will swing the pipe I3 and thus turn cams 55 and |24. The cam 55, when turned -a predetermined amount, say 30 degrees, in either direction from the neutral position illustrated will pull Bowden wire 59 and cause pawl |52 to swing upwardly and through a ratchet tooth |53 turn gear |54 far enough to turn shaft I4| one and one eighth revolutions. Since the clutch elements I4|ly and |43 are then engaged, shafts |46 and 62 will be turned clockwise by the same amount which completely resets the register. The pinion |42 and gear |54 are held stationary by pawl |52 and the register spring 1I is unable to move shaft 62 backwardly (counterclockwise) until the clutch elements disengage. These disengage after pipe I3 has turned a predetermined amount, say l5 degrees,

further, and following the disengagement of the clutch, the motor switch is closed and pumping commences. After the desired amount of fluid has been dispensed, the operator returns the nozzle to its support and, as he does so, the pipe I3 is swung toward its neutral position. The rst action is for cam |24 to move Bowden wire |29 to allow the clutch elements |43 and |43 to reengage and the motor switch to be moved to off position. This is followed by the action of cam 55, which through Bowden wire 59 will move pawl |52 downwardly until it snaps over yand behind the next succeeding tooth of the ratchet. The nozzle cannot be placed on its support until the motor switch has been opened and this occurs only at the end of the swinging movement of lever I5I. Thus, the operator must move pipe I3 completely back to neutral position before he can hang up the hose nozzle. The engagement of the spring-pressed detent 54 in a notch in disk 38 will help the operator in locating the pipe properly in neutral position.

As mentioned above, certain registers provide for resetting by a predetermined movement of the resetting shaft in one direction only without the reverse movement described. As one example, one such register requires its resetting shaft to be turned two revolutions in order to reset the number wheels to zero and then this shaft comes to rest. The invention may very readily be arranged for use with registers of this type simply by omitting the clutch means, which permit the reverse movement, and making appropriate changes in the resetting gearing. These changes are indicated in Fig. 20. Assume that the shaft 16 is connected, in a manner similar to that described, to a resetting shaft which needs to be turned two full revolutions in a clockwise direction to move the number wheels of the register back to zero. A gear 82, having ratchet teeth 85, moved by pawl 84 by Bowden wire 59,

as formerly, meshes with a pinion |55, mounted on a stud |56, fixed to plate 11. Pinion |55 has fixed thereto a gear |51, which meshes with an idler gear |58 mounted on a stud |59 fixed to plate 11 and the idler gear |58 meshes with the pinion 18 on shaft 16. As an example, gear 82 has 64 teeth, the ratchet teeth 85 are spaced 45 degrees, pawl 84 has a stroke of 45 degrees, pinion |55 has 8 teeth, gear |51 has 16 teeth and pinion 18 has 8 teeth. Thus, the pawl when pulled upwardly by Bowden wire 59 will turn gear 82, one eighth of a revolution counterclockwise or 8 teeth. This will cause pinion |55 and with it gear |51 to be turned one revolution clockwise. Gear |51 through idler gear |58 will turn pinion 18 in a clockwise direction and the full two revolutions required for resetting. The link |06 may connect pawl 84 as before to actuate the motor switch, closing it when the pawl reaches the end of its upward stroke. While pumping occurs, the resetting shaft of the register remains stationary and all of the gears described will remain stationary. After the desired amount of iiuid has been dispensed, the pipe I3 is returned to neutral position, thereby pushing on the Bowden wire and moving pawl 84 downwardly without moving gear 82, the pawl finally coming to rest beneath the ratchet tooth next succeeding the one which it had theretofore driven. Also, the motor switch will be opened when pawl 84 reaches the end of its downward stroke.

In all forms of the invention a relatively simple mechanism is provided for resetting the register and controlling the pump motor so that dispensing cannot occur until the register has been reset and so that resetting cannot occur during dispensing. This is effected simply by swinging a control member (the pipe I3 or handle ||5 or equivalent means) from one extreme to another of a predetermined range of movement and without any necessity for the relatively complicated and expensive interlocks, heretofore used between the pump control lever and the register-resetting shaft.

The invention also provides, in the case of the swinging pipe I3, a means whereby the resetting of the register and starting of the pump are effected, without requiring any particular attention or effort on the part of the operator, by the act of moving the hose nozzle into position to service the tank of an automobile.

The swinging pipe I3 also enables easy servicing of the tank of an automobile from either side of the island, on which a pump is often mounted. and enables a desirable extension of the servicing range, since the pipe can swing to any position throughout a 360 degree range. Also, the extension of the hose is effected without requiring extra exertion on the part of the operator as is required, where spring-retracted reels or other spring or weight-retracted hose-storage means are used. Such reels or means require the operator to pull the hose out against the resistance of the retracting spring and to hold it extended under tension. Here, the extension requires no substantial added effort. The operator simply carries the nozzle, wherever he wishes to go, and the pipe swings as much as required and in the direction required, and during the initial stages of the swinging in either direction resetting of the register occurs followed by starting of the pump motor.

Thus, substantially improved means have been provided for controlling a uid dispensing ap 13 "paradis, iiiateriaii'y Simplifying and facilitating the rservicing of the fuel tanks of automobiles.
