13 Claims.

This invention relates to liquid dispensing apparatus and more particularly to mechanism for indicating and registering the quantities of liquid dispensed by such an apparatus.

One object of the invention is to provide simple and eflicient means for registering the quantity ofliquid delivered by the apparatus and for resetting such registering mechanism to its initial position at the end of each delivery operation.

A further object of the invention is to provide such a mechanism in which the indicating device and the registering device may be simultaneously reset to their initial positions by the manipulation of the single operating mechanism and which will have means for permitting the continued movement of the operating mechanism when one of said devices reaches its initial position in advance of the other.

A further object of the invention is to provide such a mechanism with means for automatically preventing the operation of the resetting mechanism while the delivery mechanism is in operation and for preventing the operation of the delivery mechanism during'the resetting operation. Other objects of the invention will appear as the apparatus is described in detail,

In these drawings I have illustrated one embodiment of my invention and have shown the same as applied to dispensing apparatus of the type known as a meter pump, in which the liquid delivered is measured by a meter and the meter operates the indicating and registering devices. 5 It will be understood, however, that this particular mechanism has been chosen for the purposes of illustration only and that the invention may take various forms and may be utilized with dispensing apparatus of various kinds.

The particular dispensing apparatus here illustrated comprises a rotary pump i5 mounted within a housing l6 and driven by an electric motor H, the operation of which is controlled by a switch 18. The pump draws liquid from a suitable reservoir, such as the usual underground tank, and delivers the same through a pipe I 9 to a meter 20. The liquid passes from the meter through adischarge pipe 2| to a delivery hose 22, a portion only of which is shown. Any suitable means may be provided for actuating the switch and thus controlling the operation of the delivery mechanism. In the present instance, I have employed a switch actuating device simi-. lar to that shown in the Hanna and Bradley application filed September 5, 1930, Serial No. 479,870 new Patent No. 1,974,649. A rigid nozzle supporting member 23 is mounted on a fixed part of the apparatus within the housing l6 and extends beyond that housing to receive and support the nozzle 24 at the discharge end of the hose.

A lever 25 is pivotally mounted near the inner end of the supporting member 23 and is connected by a rod 26 with the switch IS. The outer portion of the switch actuating lever 25 is movable into a position immediately above and in contact with the'supporting member 23 and into a position spaced from the same. The connection between the lever and the switchis such that when the lever is in contact with or adjacent to the supporting member 23 the switch will be closed and when the lever is spaced from the supporting member the switch will be open. The outer portion of the lever is preferably tapered and-prevents either the nozzle or the hose being hung upon the support while the switch is closed. When the nozzle is on the support the lever is held in its spaced position and the switch cannot be closed.

Mounted above the meter 20 is a device to indicate the quantities of liquid delivered, this device being of such a character that it will indicate gallons, or other units of measurement, and fractions thereof, and it is driven from the meter. As here shown, see Figs. 1, 5 and 6, a supplemental frame or supporting bracket 21 is mounted in the housing above the meter and provided with uprights 28 in which is journaled a shaft 29 having secured thereto a gear 89 which meshes with a pinion 82 carried by the meter driven shaft 88, the gear ratio being such that theshaft 28 will make one complete rotation for each gallon, or other unit, of liquid delivered. The shaft extends beyond the housing and has secured thereto a pointer 84 which travels over a dial a mounted on the outer side of the housing I6 and graduated in gallons, or other units of measurement, and in fractions thereof. In the present instance, the indication is made on both sides of the housing and the shaft therefor. extends beyond both sides of the housing and is provided at each end with a pointer 84. These pointers make one complete rotation for each gallon delivered and the reading is upon the fractional graduations on the dial, that is, the graduations and Rotatably mounted on the shaft 28 near each end thereofare sleeves 85 and 85 which extend through the respective walls of the housing and have secured to their outer ends pointers 81 adapted also to travel over the faces of the dials and to indicate thereon the gallons of liquid delivered. Each sleeve is provided at its inner end with a gear 88 which meshes with a pinion 88 on a countershaft 49 rotatably mounted in the uprights 28 and preferably arranged above the shaft 28. The shaft 28 has secured thereto. adjacent to one of the gears 88, a trip arm or pawl 4! arranged to engage and actuate a star wheel 42 secured to the shaft 40. The trip arm 4| being rigidly secured to the shaft 28 it will be apparent that it will engage and actuate the star wheel once for each rotation of the shaft 29 and the ratio of the gears 88 and 88 is such that the indicating pointers 81 will be advanced a distance equal to one gallon on the face of the dial for each rotation of the shaft 29. The sleeve 85 is connected with the shaft 29 by a one-way clutch which will permit the shaft to rotate forwardly with relation to the sleeve and will cause the sleeve to rotate with the shaft when the latter is moved in a reverse direction. As here shown, this one-way clutch is in the form of a spring pressed pin 43 slidably mounted in the sleeve 35 and adapted to enter a recess 44 in the shaft 29, this recess having an abrupt forward wall and a tapered rear wall so that when the shaft is rotated forwardly the pin will ride out of the recess and when the shaft is reversed the abrupt wall of the recess will engage the pin and cause the sleeve to rotate with the shaft. The clutch is so arranged that when the shaft picks up the sleeve the pointers 84 and 81 will be in alinement and will move together toward their initial or zero positions. The rotation of the shaft 29 and sleeve 85 in a reverse direction so changes the relative positions of the star wheel and the trip arm 4i, that, when the pointers reach their initial positions, the trip arm will engage the end of a tooth of the star wheel and the movement of the trip arm and the shaft will be positively stopped. A detent pawl 45 is held normally in position by a weighted arm 48 to prevent forward movement or overthrow of the star wheel42 when the latter is moved forward one step by the trip arm 4i and, further, to prevent forward movement of the star wheel when the trip arm is in disengaged relation to the star wheel. The trip arm 4| is provided with a laterally extending pin 41 to engage and lift the arm 46 immediately preceding contact of the trip arm with a tooth of the star wheel 42, thus lifting the detent pawl 45 out of engagement with the star wheel and permitting the trip arm to move the star wheel forward only one step. Just prior to disengagement of the trip arm 4| from the star wheel 42 during normal continuance of the forward movement, the pin 41 will permit the arm 48 to drop and the detent pawl 45 to re-engage the star wheel 42 to prevent further forward or overthrow movement of the star wheel until the trip arm has again reached a point immediately preceding engagement with the star wheel. tional retarding device 48 affords additional re sistance to the overthrow of the star wheel. Reverse movement is imparted to the shaft 28, for resetting the indicating devices, in a manner to be hereinafter described. It is desirable that the shaft 29 shall rotate in a reverse direction independently of the meter driven shaft 88. For this purpose the gear 88 may be connected with the shaft 29 by a suitable clutch 85a which is here shown as a friction clutch which will cause the shaft to be rotated by the gear when the latter is actuated but will slip and permit the shaft to rotate in the gear when the shaft is rotated and the gear held against movement.

A device is also provided for registering the quantities of liquid delivered so that a printed record maybe taken therefrom and this registering device is, in the presentinstance, contained within a supplemental housing 48 mounted on a bracket 50 arranged at one side of the apparatus. The registering apparatus comprises a counter shaft 5i on which is rotatably mounted a quart counterwheel 52 having connected thereto a ratchet wheel 58. Also mounted on the shaft 5i is the gallons counterwheel 54 which is provided with an elongated hub 55 to which is secured a ratchet wheel 56. The two counterwheels are separate and independently operable, they being preferably separated by a stationary spacing member 56a, and in the present instance both counterwheels are provided with printing type. The shaft 5! may also carry other type wheels I56 which may be actuated manually or otherwise to record additional data but form no part of the present invention. Arranged parallel with the countershaft 5i, and preferably below the same, is a shaft 51 which is driven in accordance with the quantities of liquid delivered by the apparatus. In the present arrangement a shaft 58 extends from the housing 49 into the housing It and has at its inner end a beveled gear 59 which meshes with the gear 88 on the shaft 29. Secured to the shaft 58, within the housing 48, is a spur gear 50 which meshes with a second spur gear 6! which in turn is connected with the shaft 51 through an overrunning clutch, such as an ordinary roller clutch. 62, which is arranged to cause the shaft 51 to rotate with the shaft 55 but to permit. the shaft 51 to rotate forwardl with relation to the shaft 58. Connected with and operated by the shaft 51 are suitable devices for advancing the type counterwheels in accordance with the quantity of liquid delivered. The actuating device for the quarts counterwheel, as shown in Fig. 2, comprises a pawl carrier 58 mounted on the shaft 51, for pivotal movement and for sliding movement transversely to the shaft, the pawl carrier preferably having a longitudinal slot through which the shaft extends, as shown in dotted lines in Fig. 2. At its upper end this pawl carrier is provided with a. nose, or pawl, 64 to engage the ratchet wheel 58 of the quarts counterwheel. At its lower end the pawl carrier A frichas a laterally extending arm 85 which is acted upon by a spring 66, which spring serves to impart pivotal movement to the pawl carrier to hold the pawl in engagement with the ratchet wheel and to impart longitudinal downwardly sliding movement thereto. Rigidly secured to the shaft 51 is a four-lobe cam 61'arranged to engage a projection 68 on the pawl carrier'and move the same upwardly against the tension of the spring 68 when the shaft 51 is rotated and then release it for operation by the spring 68. The gear ratio between the shaft 51 and the shaft 29 is such that the shaft 51 will make one rotation for each gallon of liquid delivered and the four lobes of the cam 61 being distributed equally about the shaft it will be apparent that the pawl carrier will be operated four times at equally spaced intervals during the delivery of each gallon of liquid and will therefore actuate the counterwheel to register quarts. A second pawl-carrier 69, (Fig. 7) is pivotally and slidably mounted on the shaft 51, and preferably by providing it with a longitudinal slot through which the shaft extends and is provided with a nose or pawl 10 to engage and actuate the ratchet wheel 56 for the gallons counterwheel 54. This pawl is arranged on that side of the counter shaft opposite the pawl carrier 63 and therefore acts on the ratchet wheel in an upward direction. A spring 1I tends to move the pawl carrier upwardly and to hold the pawl in engagement with the ratchet wheel. A one-lobe cam 12 secured to the shaft 51 acts on a projection 13 at the lower end of the pawl carrier 69 to retract and release the same for operation by the spring once upon each complete rotation of the shaft 51, thereby causingthe counterwheel 54 to register the number of gallons of liquid delivered.

It is desirable that the counterwheels be reset to their initial or zero positions upon the 'completion of each delivery operation. For this purpose I have rotatablymounted upon the shaft 51 resetting elements, here shown as resetting gears 14 and 15 which have geared'connection with the counterwheels 52 and 54,. respectively, and, 1

in the present instance, mesh directly with gears 16 and 11 formed integral with the counterwheels. Rotatably mounted on the shaft 51, between the resetting gears 14 and 15, is an actuating element or gear 18 and means are provided whereby the rotation of this actuating gear will cause the resetting gears to be rotated to move the counterwheels to their initial positions. As here shown, the resetting gears 14 and 15 are provided, respectively, with hubs 19 and which extend inwardly toward the actuating gear and are provided at their inner ends with one-toothed ratchet wheels 8| and 82. It is also desirable that the shaft 51 should be actuated to reset the cams 81 and 12 to their initial positions. In the present construction I have mounted onthe shaft 51 two sleeves 83 and 83a. The sleeve 83a is rotatable on the shaft and is secured to' andforms a hub for the gear 18, and the hub 80 is rotatably mounted on this sleeve 83a. The sleeve 83 is rigidly secured to the shaft and the 'hub 19 is rotatably mounted thereon. Rigidly secured to the sleeve 83, between the ratchet wheel BI and the actuating gear 18, is a one-toothed ratchet wheel 84. Pivotall'y mounted on one side of the actuating gear 18 is a spring pressed pawl 85 the nose of which is broad enough to engage the teeth of both the ratchet wheels M and 84, and pivotally mounted on the opposite 'side of the'actuating gear is a spring pressed pawl 88 adapted to engage the ratchetwheel 82. Consequently when the actuating gear is rotated in a forward direction the pawls will pick up the respective one-toothed ratchet wheels 8|, 82 and 84, in whatever positions they may occupy, and restore the counterwheels and the cams to their initial positions.

The necessary predetermined movement may be imparted to the actuating device 18 in any suitable manner. In the present instance, this is accomplished by an operating mechanism comprising a shaft 81 provided with an actuating handle 88 (Fig. 1), and having mounted thereon a gear 89 provided with a sufficient number of teeth to impart one complete rotation to the actuating gear 18 upon each rotation of the shaft 81. In the present apparatus this operating mechanism operates not only the resetting devices but also a printing mechanism, and the gear 89 is a mutilated gear of such a character as to permit the completion of the printing operation before the resetting operation begins. The printing mechanism is no part of the present invention. Briefly it comprises a platen 90 carried by a lever 9| which is acted uponby a spring 92 to cause the platen to engage an ink ribbon 93, between which and the type faced counterwheels extends a record strip 94. The platen is held normally in an elevated position by means of a cam 95 mounted on a shaft 96 above the shaft 81 and connected thereto by gears 91. The cam is so arranged that the first'movement of the shaft 81 will release the platen for printing movement and a short further movement of'the shaft will cause the cam to lift the platen away from the type wheels. To permit .of this operation of the platen the gear 89 of the operating mechanism is provided with a smooth peripheral portion 98 which contacts with a corresponding part 99 of the actuating gear, this contact serving to hold the actuating gear normally against rotation. When the shaft'81 has been rotated far enough to bring the toothed portion of the gear 89 into engagement with the teeth of the actuating gear 18 the printing operation will have been completed and the counterwheeels will be reset to zero.

" Means are also provided to positively limit the movement of the shaft 81 to one complete rotation and, as shown in Figs. 2 andll, this means comprises a pair of oppositely extending arms I 00 and IOI rigidly secured to the shaft 81; The arm I00 has in its lower edge a recess I02 and the arm IOI has a laterally extending stud I03. Pivotally mounted below the arms I00 and MI is a pair of rigidly connected dogs I04-and I05. The dog I04 has a tapered nose adapted to enter the recess I02 in the arm I00 and to positively stop the movement of the shaft 81. A spring I06 connected with the dog I05 tends to move the two dogs about their axes and to carry the dog I04 out of line with the arm I00. When the parts are in their normal positions. the end of the doe I04 is seated in the recess and is thus held against movement by the spring. When the shaft 81 is to be operated a short movement is imparted to the crank 88 in a reverse direction, thus moving the arm I00 out of engagement with the dog I04 and permitting the latter to be retracted by the spring, thereby releasingthe shaft for rotation. As the shaft approaches the end of one complete rotation the stud I03 on the arm IOI will engage the dog I05 and move'thc dog I04 into line with the recess in the arm I00. The dog I05 is of such length that the stud I03 will clear the same just before the arm I00 contacts with th dog I04 but the tapered end of the dog I04 will have entered the recess I02 before the stud clearsthe dog I05 and the dog is thus prevented from moving out of line with the arm and the shaft is positively stopped.

In order to prevent the counterwheels from being overthrown by momentum at the end of the resetting operation I have provided means for positively stopping the movement of the resetting gears at the end of one complete rotation. (See Figs. 2, 7 and 8.) For this purpose the actuating gears 14 and 15 are provided with parts forming stops, such as laterally extending pins I01. Pivotally mounted on a fixed part of the structure, preferably beneath the shaft 81, is a lever I08 which is shown in the form of a bell crank, one arm of which is provided with two upwardly extending parts I09 arranged to be moved into and out of the path of the respective pins I01 by the pivotal movement of the lever. A spring IIO acts on the lever to hold the parts I09 normally out of the path of the pins. The second arm of the lever extends upwardly and has at its upper end a nose III arranged to be acted upon by a cam II2 on the shaft 81; This cam is so arranged that as the counterwheels approach their initial positions, during the resetting operation, the lever will be rocked about its axis and the parts I09 moved into the paths of the respective pins I01 and will be retained there until the counterwheels have been restored to their initial positions, thus providing a positive stop to interrupt the movement of the counterwheels. At the instant that the counterwheels reach their initial positions the cam II2 clears the nose III of the lever and the lever is moved by the spring IIO to its inoperative position, thereby releasing the resetting gears and counterwheels for operation.

The mechanism which operates the resetting means for the counterwheels also actuates the shaft 29 to reset the indicating devices. As here shown, a shaft H3 is connected by gears II4 with the shaft 81 for rotation therewith and is also operatively connected with the shaft 29. asmuch as the complete rotation of the shaft 81 is necessary to reset the counterwheels and the indicating pointers may be returned to their initial positions with a less movement of the shaft 81 it is desirable that the connection between that shaft and the resetting means for the indicating devices should be of such a character as to permit the shaft to continue its rotation after the pointers are in their initial positions, that is, after the reverse movement of the shaft 29 has been stopped by the contact of the trip arm with the star wheel. For this purpose I have interposed between the shaft 81 and the shaft 29 a slip connection. As here shown, the shaft H3, which is geared to the shaft 81, as shown in Fig. 4, is connected with the hub II5 of a plate or supporting member I I6, which hub is rotatably mounted in a bracket II1. Arranged in line with the shaft H3 is a shaft II8, forming in effect an extension of the shaft H3 and having secured thereto a gear I I9 which meshes with a pinion I 30 upon the shaft 29, as shown in Fig. 5. Rigidly secured to the shaft IIO, adjacent to the supporting member I I6, is a friction drum I2 I. Pivotally mounted on the supporting member I I6are friction members,

- here shown as a pair of friction shoes I22, which extend about the periphery of the drum |2I and are pressed into frictional contact therewith by a spring I28. The frictional contact between the shoes nnd the drum is sufficient to cause the shaft 29 and its associated parts to rotate with the shaft 81 but when the movement of the shaft 29 has been positively stopped with the pointers in their initial positions the shoes I22 will slip on the drum and permit the further movement of-the shaft 81, when such further movement is.

necessary to complete the resetting of the counterwheels. It is necessary, however, that the connection between the shaft 29 and the shaft 81 should be interrupted during the delivery operation of the apparatus, to permit the free rotation of the shaft 29 by the meter. I have therefore provided means for automatically separating the friction members and thereby disconnecting the shaft II 8 from the shaft IIJ. In the construction shown, a cam shaped expanding device I24 is mounted on the supporting member or plate II6 between the free ends of the friction shoes I 22 and is provided with a laterally extending arm I25 having at its outer end a head I26. A fixed actuating device is arranged to be engaged by the head I26 of the arm I25 and to cause the latter to actuate the expanding device to move the shoes out of engagement with the drum when the shaft 81 of the operating mechanism is moved to its initial position. This actuating device is shown as a stud I21 mounted on the bracket II1 beneath the friction driving element and so arranged that the last portion of the movement of the supporting member or plate II6 by the shaft 81, at the end of the resetting operation, will move the head I26 onto the stud I21, thereby causing the arm I25 to actuate the expanding device to move the shoes out of frictional contact with the drum and releasing the shaft II8 for rotation .by the shaft I29. The head I26 remains in engagement with the stud I21 when the movement of the shaft 81 is interrupted at the end of the resetting operation, thus rendering the frictional connection between the shaft 81 and the shaft I II inoperative during the delivery operation. The first portion of the movement of the shaft 81 upon the next resetting operation will cause the supporting plate I I 6 to move the head I26 of the expanding device out of engagement with the stud' before the mutilated gear 89 operatively engages the actuating gear 18, thereby permitting the shoes to again grip the drum and connect the shaft 29 with the shaft 81 before resetting movement is imparted to the counterwheels.

For the purpose of preventing the operation of the resetting mechanism while the delivery mechanism is in operation and for preventing the operation of the delivery mechanism while the resetting mechanism is in operation, I have provided an automatic locking mechanism. (See Figs. 1 and 4.) The shaft 81 of the operating mechanism for the resetting device is extended through the wall of the housing 49 and into the housing I6 and has rigidly secured thereto, Jithin the housing I6, a disk I28 having a peripheral notch I29, this disk constituting a locking member rigidly connected with the operating mechanism. A second locking member is mounted adjacent to the disk I28 and, as here shown, is in the form of a lever I20 one end of which is arranged alongside of the disk I28 and is adapted to be moved into the notch I29 when that notch is in line therewith. The opposite end of the lever is connected by a rod I 3| with the switch actuating lever 25, the connection being so arranged that when the lever is in its inoperative position, that is, when the switch is open, the locking member I30 will lie alongside of but out of engagement with the disk I20. If the switch act...

ating lever is moved to its operative position, to close the switch, while the resetting mechanism is in its normal position, the locking member I30 will be caused to enter the recess I 29 in the disk I28 and will thereby lock the resetting mechanism against operation so long as the switch is closed. If the shaft 81 of the resetting mechanism is actuated while the switch actuating lever is in its open position the unn tched portion of the disk I28 will be moved in line with the locking member I30 andthe switch actuating member thus locked in its inoperative position until the resetting operation has been completed and the shaft 81 restored to its initial position.

While I have shown and described one embodiment of my invention I wish it to be understood that I do not desire to be limited to the details thereof as various modifications may occur to a person skilled in the art.
