:LIQUID-IDISPIEINSING'l APPARATUS.

This invention relates to liquid dispensing apparatus and is in the nature of an improvement on the dispensing apparatus shown and described in the application for patent filed by 5 me March 14, 1925, Serial No. 15,471. v

That a paratus comprises a delivery bowl into which extends a vertically adjustable discharge pipe which communicates :with a flexible delivery hose and this discharge pipe and delivery hose constitute the only means by which the liquid may be withdrawn from the bowl. When it is necessary to drain the bowl without making a delivery of liquid the delivery hose is connected with a drain pipe leading back to the storage reservoir.

One object of the present invention is to provide meansfor correctlyv registering all liquid actually delivered by the apparatus; and to this'end it is a further object to provide la registering device which will be operated according to the adjustments of the discharge pipe and will be correctly operated regardless of the speed at which those adjustments are made.

In the pump of the aforementioned application it is necessary to move the discharge.

l pipe to its lowermost position inorder to i drain the bowl and when no delivery ismade such an adjustment will cause an inaccurate registration on the registering device. It is therefore a further object of the invention to provide means for draining the bowlfthrough the delivery hose when the discharge pipe is in its uppermost position; and, further, to so control said'draining means that it will be operative only when the delivery hose is properly connected with the drain. v

A further object ofthe invention. is to provide means for preventing the inadvertent movement of the actuating device, which might cause the registering device to be actuated when no delivery was made.

Liquid is introduced into the bowl by means of a pump and ifthis pump is free for opera- 'the delivery pipe is in its uppermost position.A Other objects of the invention will appear:

as the device is described in detail.

In these drawings I have illustrated one embodiment of m invention but it will'be understood that t is particular embodiment `has been' chosen for the purpose of illustrationA only and that the mechanism may take various forms .without departing from the spirit of the invention. v

As here shown, the apparatus comprises referably comprising, a trans arent cylindrical wall mounted on a.- suita le'l base 2. The delivery bowl is car- `ried by a hollow standard 3 upon the upper end of which the base 2 for the 4delivery -bowl is mounted.A Mounted -in the lower portion of the hollow standard is' a pump 4 with which is connected an inlet pipe 5 the upperend of which extends. into-the bowl and is, in the present'` instance, provided with a downturned end. portion or gooserneckl. The bowl maybe of any suitable capacity and, in the present instance, has a measuring capacity of ten gallons. Mounted'within the bowl is an overflow pipe7 the open upper end of which is arranged atthe ten gallon level within the bowl-so that all liquid pumped into the bowl in excess of ten gal- 110 lons will escape through the overflow pipe. This overflow pipe extends downwardly from the hollow standard and is connected at its lower end with adrain pipe 8 which leads back to the storage reservoir. Slidably mounted in the base 2 of the bowl is a discharge pipe 9 the lower portion of which extends into and is in open communication with a well 10 depending from the lower end lo of the base. -A delivery pipe 109 is in open communication with the well, and consequently with the discharge pipe, and aflexible delivery hose 110 is connected with this delivery pipe and is provided with ay nozzle 111 for connecting the same with a tank ot van automobile,-or other receptacle` towhich the liquid is to be delivered. The liquid can be returned to the storage tank from the bowl 1 through this delivery hose and for this purpose the hose is connected with the 'drain pipe 8. Connected with the drain pipe 8 is an inlet chamber or socket 113 adapted to receive the nozzle 111. The fiow ot liquid through the delivery pipe and hose is controlled by a valve 114 which, in the present instance, is operated by a shaft 115 having secured thereto a handle 116 and having extending from that side thereof opposite the handle -116 a weighted arm 117 to hold the valve normally in its closed position. The discharge pipe may be adjusted to various .positions within the bowl to .cause the discharge of the desired quantity ot liquid. Preferably the bowl is provided with indieators, as shown at 12, to indicate to the operator and customer the amount of liquid that will be delivered through the discharge pipe when't'he latter is in an adjusted position. Inasmueh as the bowl is first filled to 40 capacity and the discharge pipe then lowered to the desired position the indicators 12 are graduated from top to bottom so that when the discharge pipe isin line with the zero indication no liquid will be discharged 'therethrough and when it is in line with the ten gallon indication ten gallons of liquid will be delivered therethrough. Preferably -the upper end of the discharge pipe will be arranged slightly above the ten gallon level of the liquid in the bowl when the pipe is in its uppermost position and, it desired, means may be provided tor closing the upper end of the discharge pipe when it is in lts uppermostl position soI as to prevent liqluid from splashing into the same while the bowl is being filled. As here shown, a cap 13 is slidably mounted in the top of the bowl in line with the upper end of the discharge pipe and is pressed downwardly by a spring 14 so that when the discharge pipe 1s moved to its uppermost position it will` /f/ engage this cap and the cap will be held in /f' firm contact therewith. The discharge pipe may be actuated in any suitable manner. As

y here shown, a rod l5is connected with the lower end of the pipe and extends through a v stuling box 16 at the lower end 'of the well 10. The outer end of this rod is connected with a bracket 17 which is slidably mounted Aon a guide rod 1S and has connected therehandle 22to enable the operatortodeterini-ne the position of the discharge pipe without the, necessity ot looking up at the bowl, which is usuali)Y located above his head. As shown in Figs. 1, 5 and 6. this dial is provided' with a plurality ot indications numbered from 1 to 10 inclusive and these indications are so arranged with relation to the handle 22 that when this handle is in line with any one ot such indications the discharge pipe will bc in line lwith the corresponding indication 12 on the bowl. In the present device, the handle 22 is provided with lan enlarged portion 23 having an opening arranged to be brought into line with any one of the indications, so that the latter will be visible through the opening in the handle. I have in this particular apparatus provided means which may be set to atord a positive stop for the handle when the latter has been moved to a position to set the discharge pipe to deliver the dcsired quantity of liquid. To this cnd the several indications associated witl1the"'handle 22 are formed on the heads 24 of a series of plungers 25 which a're slidably mounted in the walls of a housing 26 mounted within thel standard 3 and in line with an opening therein, so that the front wall ot this housing in ctl'ect constitutes a dial. Iigidly secured toy each of the plungers 25 within the housing 26 is a stop 27 which is movable with the plunger into and out of line with a stop tinger 28 rigidly secured to the shat't 21. lVhen the plungers are all in their forward or outermost positions all the stops will be out of the path of the stop linger 28 and the shat't may be rotated through a complete revolution. lVhen it is desired to set the discharge pipe to deliver a certain .quantity of liquid. say si\ gallons, the correspomling plunger 25, bearing the indication is pressed inwardly, thus moving the stop 27 to a position ncarthe rear wall ol the housing and into the path of the stop arm 28 so that when the handle 22 is moved into line with the indication (5 the stop finger will engage the stop and positively prevent. further movement ot the -handle. .In order that the stop may be adjusted to secure absolute accuracy in the position of the discharge pipe I have mounted therein a.

lAs here shown, means are ably mounted screw 29 which may be adjusted with relation thereto and secured in adjusted positions by means of a lock nut 30, the end of the screw forming the contact portion of the stop which is engaged by the stop arm 28. To prevent any turning movement of the stops about the axes of the respective plungers, each stop has a wide base portion 31 theends of which rest upon the cylindrical i on the opposite sides of the plunger, thus permitting free sliding movement vof the stop but preventing any displacement lthereof when it is engaged bv the stop finger 28. Each plunger has formed therein two recesses 32 either of which may be engaged by a spring pressed detent 33 carried by the houS- ing 26, which detent serves to hold the plunger against accidental vdisplacement but will yield to permit movement of the plunger when positive pressure is applied thereto. provided for quickly and easily retracting the plunger which has been operated. This means comprises a lever 34 pivotally mounted on the handle 22 and having its inner end arranged normally in a plane on the inner side of the heads of the plungers, when the latter have been moved inwardly. A spring 35 acting on the other end of the lever holds the inner end thereof normally in this position. Consequently when one of the plungers has been operated and the handle 22 moved into line therewith the end of the lever 34-will lie 'on the inner side of the head of that plunger 'and by pressing on the outer end ofthe lever the plunger may be withdrawn'. Thus if the customer desires 'additional liquid after the quantity originally requested has been delivered the one plunger maybe withdrawn and another plunger depressed and the handle moved into line therewith. .y

Associated with the actuating device for the discharge'pipe `ivs'a register which will be operated by said actuating device to accurately register the quantities of liquid delivered by the apparatus. This register may take various forms and, as her'.` shown, it

comprises a group of counterwheels 36 of a'.v -well known construction and which may be provided with transfer mechanism of any suitable kind, thisv portion of theregister forming no part of the invention. Rigidly connected with theunits counterwheel of the register is a ratchet wheet` 37 which is le11- gaged and actuated by a pawl l38 held in yieldable engagement therewith by a spring 39. The pawl' 38 is mounted on a suitable pawl carrier which, in the present instance, isslidfor reciprocatory movement transverse to the axis ofthe counterwheels. As here shown, the register is mountedwithin a casing 40 arranged wit-hin the hollow stand- --ard 3 and having an opening 41arranged in line with the corresponding opening in the wall of the standard. The pawl carrier is wall of the housing 26l shown in the form of a slotted plate`42 mounted on pins 43 carried by the housing -40 and having an upwardly ext-ending lug 44 on which the pawl 38 is pivotally mounted. The inner portion 45 of the pawl carrier is pivot- 4ally mounted on the body of the pawl carrier for movement about a vertical axis, as shown at 46, and extends into the path of a series of projections or pins 47 carried by the rack 19, which actuates the discharge pipe. These pins are spaced apart such 'distances that a in will engage' the beveled end of the part 45 of the pawl carrier and actuate the pawl as the end of the discharge pipe is brought into line with each successive indication 12 on lthe bowl, thus causing the register to record the number of gallons of l'liquid which v the discharge tube is set to deliver. The lower side of the part 45 o'f the pawl carrier is beveled, as shown at 48, in Fig. 11, so that when the racl 19 is moved lupwardly to restore the discharge pipe to its normal position the pins will engage this beveled surface of the part 45 and move the same out of the path thereof so that the pawl carrier will not be operated.

.A spring 49 acting on a pin 50 on the part 45 of the pawl carrier holds the same yieldably in its normal or operative position. In the operation of an apparatusvofthis kind the rack 19 is sometimes moved very rapidly and should the pawl carrier lag and not move promptly into its loperative position a suc'- ceeding pin 47 might pass the same without operating the register. I have therefore provided means for positively restoring the paw carrier to its operative position before a succeeding pin on the rack 19 moves to a position to engage the same. As here shown.I a lever 51 is pivotally mounted between its ends within the housing 40 and has one end in contact with the part 45 of the pawl carrier, which in the present arrangement is offset from the body 42 of 52 acts on the lower end of the lever to hold the same normally in engagement with the pawl carrier and to move the pawl 'carrier toward its operative position. The lower end of the lever 5l has aprojection or nose 53 lwhich -is-so arranged that when the pawl carrier isin its normal or operative position thisprotection-will lie out of the path of the pins 47 onthe rack and will not be enga-ged therebyvbut themovement ofthe pawl carrier the carrier. A spring j out-of its normal position will cause this prothe lever will be moved.

eact-uates eithr the the next succeeding pin moves into a position to 'engage the pawl carrier and "if the spring has not restored the pawl carrier to its normal position it will be positively restored. by the action of the pin on the lever, in time to be engaged by the next succeeding pin.- A spring 54 engages the ratchet wheel 36 of the register to prevent the reverse movement thereot and also exerts sufficient pressure on the ratchet Wheel to resist the tendency of the register to overthrow due to the rapid operation thereof. I prefer, however, to provide positive means to prevent the overthrow of the register and for this purpose I have mounted within the casing a cam block 118 which is so arranged that it will be engaged bythe end of the pawl 38 as the latter approaches the end of its operative movement, thus causing the tooth of the pawl to be pressed into engagement with the ratchet Wheel and to prevent the overthrow thereof.

The handle 22 for the actuating device' for the discharge pipe is so arranged that it might be inadvertently moved by the operator, or by unauthorized persons, to such an extent as to actuate the register when no delivery is made, thus causing a false registration on the register. To avoid this inadvertent operation of the lever I have provided means for so controlling the actuating device that the oper-l ator must voluntarily release the same before it can be manipulated. As shown in Figs. 9 and 10 I have mounted on a bracket 55 two pawls 56 and 57 which are independently movable about a common axis and each of which is movable into and out ofl engagement with the teeth of the gear 20. A rod 58 is slidably mounted in .the bracket 55, `extends through the forward wall of the standard 3 and is provided at its outer end with Van actuating knob 59. Rigidly secured to this rod, between the pawls 56 and 57 is an abutment 60 arranged to engage projections 61 on the two pawls. The projections are so arranged that when the abutment 60 is in engagement with one of them'it will be out of engagement with the other. Preferably the ends of the abutment are beveled so that it will engage the abutments with a camming action and move the pawls about their axes. When the rod 58 is in its innermost position, as shown in Figs. 9 and 10, the abutment will be in contact with the projection on the pawl 56 and this pawl will be held in an inoperat-ive position but the pawl 57 will be free for movement and will be held by gravity in contact with the teeth of the -gear 20 thus locking that gear against reverse movement. If the actuating mechanism has been operated to move the stop linger 28 into engagement with one of the fixed stops this will prevent the further forward movement of the handle and consequently it will-be positively locked against movement until the operator stop which is limiting the forward movement of the handle or the pawl 57 which prevents the reverse movement of the handle. The handle is thus locked against movement at the end of each delivery and upon the completion of the delivery the operator will draw the rod 58 outwardly, thus causing the abutment to engage the projection 61 on the pawl 57, move that pawl into an inoperative posit-ion and permit the paw'l 56 to move into engagement with the gear': The gear and handle 22 are thus released for reverse movement but are held against forward movement. When the handle reaches its normal position it is locked against further reverse movement. Any suitable stop may be provided for this purpose but, in the present instance, I have mounted a stop sleeve 62 on the guide rod 18 for the rack 19, this sleeve being arranged between the bracket 17 and a fixed part of the standard, and serving to positively check the reverse movement of the actuating mechanism. Preferably this stop is so arranged that the handle may move in a reverse direction slightly beyond its zero position.' the numeral 10 on the dial representing both the zero position and the ten gallon position. By moving the handle slightly beyond the zero position the upper end of the discharge pipe is moved to a position slightly above the ten gallon level in the bowl, as hereinbefore described. When the actuating device is in contact with this stop and the pawl 56 is in contact with the gear the actuating device is again locked against movement in either direction and it is necessary for the operator to manipulate the rod 58 before he can operate the mechanism. The vabutment 60 on the rod 58 is so arranged with relation to the stop 61 that it may be moved into an intermediate position in which both pawls will engage the gear, thus positively locking the gear against movement in either direction. The knob 59 is provided with an apertured lug 63 arranged to be moved into line with an apertured lug 64 on the standard 3 when the abutment is in its intermediate position. By inserting a lock 65 through the apertures the rod 58 may be locked in this intermediate position and the actuating mechanism thus locked against all movement.

If it is necessary to move the discharge pipe to its lowermost position in order to drain the bowl when no delivery is being made a record will be made on the register which does not represent a delivery of liquid. I have therefore provided means for connecting the bowl with the delivery pipe independently of the discharge pipe, which connecting means is so controlled that the connection can be established only when the delivery hose is connected with the drain pipe, thus preventing the delivery of liquid through the delivery hose without the registration of the same o n the register. As shown more pari ticularly in Fig. 2 the bowl is connect-ed with the well by a by-pass 66 which, in the present instance, is formed in the base 2 but which in practice might comprise a separate pipe. A valve 67 is seated at the inner end of this by-pass and its stem extends downwardly through the base and is connected -at its `lower end with an actuating rod 68. A spring 69 acts on the stem of the valve and rod 68,

to hold the valve normally in its closed position. The overflow pipe 7 and the nozzle socket 113 are connected with the drain pipe 8 through a housing 70. Mounted in this housing is a rock shaft 71 with which is rigidly. connected an arm'72 which extends into a position in which itl will be engaged by the end of the nozzle 111 when the latter has been fully inserted in the socket 113 thus caus- The connection between the socket 113 and the drain pipe 8 is also controlled by a valve which is connected with the rock shaft 71 as set forth 1n the above mentioned application but as this valve forms no part of the presentinvention it is not here illustrated. In order that the bowl may be drained it vis necessary that both the valve 67 and the valve 114 be opened and I prefer to open both of these valves automatically when the nozzle is inserted in the socket, thus causing the bowl to be drained without further action on the part of the operator.- For that purpose I have rigidly secured to the valve actuating shaft 115 an armv74 the end of which is preferably bifurcated to embrace the actuating rod 68 for the valve 67. This rod is provided with a shoulder 75 which engages the lower side' of the arm 74 so that when the rod 68 is operated to open the valve 67 the shoulder 75 will engage the arm 74 and rotate the shaft 115 in a vdirection to open the valve 114. It will be noted, however, that the arm 74 may be moved upwardly relativelyl to the actuating rod 68, thus permitting of the operation of the valve 114 by the handle 116 without disturbing the valve 67.

To prevent the fraudulent manipulation of the valve 67, when the delivery lnozzle is not in the socket 113, as by the insertion of a dummy nozzle or a piece of pipe into the socket, I have provided means for locking the shaft 71 and arm 72 in their normal ositions. As shown in Figs. 12 and 13 this ock comprises an arm 76 rigidly secured to the rock shaft 71. A locking lever 77 is' pivotally mounted on the housing so that one end thereof may be moved into and out of the path ofthe arm 76. Preferably the contacting ends of the arm 76 and lever 77 are beveled to facilitate the relative movements thereof. The other end of the lever 77 is connected with a rod or plunger 79 which is slidably mounted in a housing 80 and is held normally in its outermost positlon, by a sprlng 81 and when in this position the rod 79 wlll hold the locking lever 77 in the path of the arm 76 and thus prevent the movement of the valve actuating arm 72. The rod 9 is positively locked in its outermost posltlon and, in the present instance, I have secured to the outer end of the rod a lock 82 whlch is cylindrical in form and is slidably mounted in the housing-80 and which is provided w1th a key controlled mea-n s for securing the same to the outer end of the housing so as to lock the ro d 79 against inward movement. This lock 1s here shown as of ordinary construction and comprises a key barrel 83 adapted to recelve a. key 84 by means of which the lock may .be manipulated to release the plunger for 1nward movement. It will be noted that the cylindrical lock casing 82 when in its outermost position extends some distance beyondl the end of the socket 113. The nozzle 111 1s provided at its outer end with a. circumferential lange 85 having an offset portlon 86 larranged to engage the projecting lock casing 82 when the nozzle is inserted into the socket. Because of the shapes of the` nozzle and of the socket the nozzle can he inserted in the socket in one position only and when in this position the projecting part 82 of the nozzle will engage the end of the lock casing. The key 84 is preferably carried by the proJectrng portion 86 of the nozzle so that it may be 1nserted in the key banrel Vofthe lock when the nozzle is inserted in the socket. Preferably the key is retained on the nozzle by means of a s ring 87 which will permit of its manipulatlon to actuate the lock. It will be apparent, therefore, that when the nozzle is inserted within the socket the projecting lock casing will prevent the same from being fully 1nserted and it will be necessary to insert the key 84 and unlock the rod 79 before the 1nsertion ofthe nozzle may be completed. In

racticethe nozzle will be inserted and the key operated'and a retaining lever 88 moved into engagement with the flange 85 on the a nozzle and pressed downward to force the nozzle fully into the socket to cause 1 t to actuate the shaft 71. The lever 88 has an aperture 89l which may be moved into line with an a erture in a bracket 90 to receive a lock 91t us permitting the nozzle to be locked 1n the socket. -Obviously it is not essential that the lock casing shoul :projectbeyond the end of the socket and form a stop for the nozzle but the arrangement is such that the operator will quickly' see what is preventing the insertion .of the nozzle and will not attempt to force the nozzle into the socket, as lie-might do if its inward movement wereprevented only by the arm 7 2 on the shaft 71, and which might result in breakage of the parts. When the nozzle is locked in the socket by the lever 88 andthe controlling rod 58 for the actuating device is locked in its intermediate position the apparatus is completely locked up and no liquid can be withdrawn therefrom and the register cannot be manipulated.

, As has been stated, the liquid is introduced into the delivery bowl by means of a pump and obviously it' this pump is free to operate at all times the operator can set the discharge pipe in a lowered position, thus causing the registration of a corresponding amount oi liquid, and then, by operating the pump, cause liquid to continue to flow through the discharge pipe in a quantity in excess of that which has been registered. To prevent liq- 'uid being thus withdrawn from the apparatus without being registered I have applied to the pump a positive lock which can be released only when the discharge pipe is in its uppermost position, in which position no liquid can enter the same. In the present ap,- paratus, see Figs. 1 and 8, the pump 4 comprises an actuating bar or rack 92 which meshes with a toothed segment 93 rigidly secured to a rock shaft 94, one end of which extends beyond the wall of the standard 3 and has secured thereto an operating handle 95, the manipulation of which will impart reciprocatory movement to the pump actuating rack 92. Pivotally mounted on a supporting bracket96 is a locking member 97 which is here shown in the form of an arm having at its lower end projections or teeth 98 adapted to engage the internal series of teeth 99 carried by the segment 93. A spring 100 acts on the arm 97 to hold the same normally in locking engagement with the segment, and thus prevent the operation ot the latter. In order to positively retain the locking member' 97 in locking engagement with the segment I have mounted on the bracket 96 a locking member or tapered block 101 which is movable into a position between the arm 97 and a fixed abutment 102-on the bracket 96 and will engage these parts with a wedging action so as to positively prevent all movement of the arm 97. The arm 97 is provided with an oii'set portion 103 which contacts with the locking member 101 and which provides :tor the movement of the arm 97 with relation to the locking member 101 when the latter has been moved out of engagement with said offset portion. The locking member or wedge 101 is rigidly connected with an upwardly extending rod 104 the upper end of which is connected with the actuating device for the discharge pipe in such a manner that the locking member 101 will be moved to an inoperative position only when the actuating device is operated to move the discharge pipe to its uppermost position. In the present instance, the upper end of the rod 104 is provided with a laterally extending projection 105 which overhangs the upper edge of the bracket 17 of the actuating device and, as here shown, is bifurcated to embrace the rod 15 which connects the actuating device with the discharge 97 is an arm 107 which embraces the rod 104 just above the locking member 101 and which is so arranged with relation to the locking member that the latter will engage the arm .107 as soon as it has been moved out of contact with the offset portion 103 ot' the arm 97, whereby the further movement of the locking member 101will rock the arm 97 about its axis into an inoperative position with relation to the segment 93. Upon the iirst downward movement of the discharge pipe the bracket 17 will move downwardly and the spring 106 will move the rod 104 downwardly thus moving the locking member 101 away from the arm 107 and releasing the arm 97 for movement by the spring 100 into its operative position andas soon as the arm 97 has been moved into its operative position the locking member 1-01 will enter the space between the arm and the abutment 102 and thus positively lock the pump against operation.
