UNITED STATES PATENT OFFICE REGISTERING MECHANISM William M. Carroll, Dayton, Ohio, assignor to Augustine Davis, Jr., Cincinnati, Ohio This invention relates to registering mechanism for liquid dispensing apparatus.

One object of the invention is to provide simple and efiicient mechanism controlled by the dispensing apparatus for setting up on a register certain items relating to the liquid dispensed, such as the quantity of liquid delivered and the money value thereof.

A further object of the invention is to provide such a mechanism which may be interposed between the dispensing apparatus and a register,

both of known construction, without a substantial modification of either.

A further object of the invention is to provide such a mechanism in which the items relating to each unit of liquid delivered will be accumulated, or totalized, during the delivery of the liquid, and then transferred to thegregister after the delivery has been completed.

A further object of the invention is to provide such a mechanism in which the individual items may be accumulated and then, transferred to the register and in which both the "accumulator and the register will be power operated, and which will have means controlled by the transfer mechanism to disconnect the accumulator from the operating means at the beginning of the transfer operation and forconnecting the operating means with the register on, the completion of the transfer.

A further object of the invention is to provide such a mechanism having means ior rendering the dispensing apparatus inoperative during the transfer operation.

A further object of the invention is to provide such a mechanism having means to compel the operator to transfer the vrecordat predetermined intervals. H o

Other objects of the invention will appear as the mechanism is described in detail. e

In these drawings I- have illustrated one embodiment of my invention and have shown the same in connection with a liquid dispensing apparatus of a well known type. It will be understood, however, that this particular embodiment has been chosen for the purpose of illustration only and the mechanism may take various forms and may be used in connection with dispensing apparatus of various kinds.

The dispensing apparatus here illustrated comprisesa vertical standard or housing 1 at -the upper end of which are mounted two measuring receptacles, 2 and 3, which are here shown in the form of glass cylinders of identical size, each hav-- ing a capacity of one gallon, or othersuitable measuring unit. vEach receptacle has at its upper end a; vent 4, the vents of the two receptacles being connected by a pipe 5. Each ventis con- 0 trolled by a valve 6 which is connected with a float 7 so arranged that when the receptacle is filled the float will close the valve. Mounted in the lower portion of the standard or housing 1 is a pump 8 which may be operated in any suitable manner. In the present instance it is motor driven and is connected by a pitman 9 with an electric motor 10, through suitable reducing gearing contained within the casing 11. The inlet of the pump is connected by a pipe 12 with a suitable source of liquid supply, such as an underground reservoir, and the outlet of the pump is connected by a pipe 12a with an inlet pipe 13 formed in the casing 14 constituting the upper part of the standard and on which the

twin receptacles

2 and 3 are mounted. This inlet conduit 13 is provided with

branches

15 and 16 leading respectively to

valve chambers

17 and 18 whichare connected with the respective measuring receptacles by

passageways

19 and 20.. Thyalvechambers 11 0 arealsoconnectedattheirinnerendswith'any outlet conduit 21 the outer end of which is connected with a discharge pipe 22. Mounted in each valve chamber is a piston valve, 23 and 24, the two valves being rigidly connected by a rod 25; so that they will move in unison and being so arranged that when moved tothe limit of their movement in one direction the measuring receptacle 2 will be connected with the discharge pipe and the measuring receptacle 3 will be connected with theinlet or supply pipe. When the valves are shifted to the other limit of their movement the measuring receptacle 2 will be connected with the inlet or supply pipe and the measuring receptacle 3 will be connected with the discharge. pipe. Arranged between the two passageways l9 and 20 is a cylinder 26 having mounted therein a double ended piston 27'the'ends of which are exposed to the liquid in the respective passageways. When that receptacle which is connected with the supply pipe is filled the continued operation of the pump will subject the liquid to pressure suflicient to shift the piston 2'7 lengthwise ofthe cylinder 26. Connected with the piston 27 is a crank arm 28 rigidly secured to a shaft 29 which extends through the outer wall of the casing 14 and is connected with the valves 23 and 24 in such a manner 'as to shift those valves. As here shown, an arm 30 is secured to the outer end of the shaft 29 and is connected with a second arm 31 which is connected with an arm 31a rigidly secured to a-shaft '32 also extending through the wall of the casing and having secured to its inner end an arm 33 which is connected with the valve rod 25. The arms 30 and 31 constitute in effect a toggle and the arm 31 is longitudinally movable in a part 34 which is connected with the arm 31a and is acted upon by a spring 35, the arrangement being such that when the two arms are brought into longitudinal alinement the spring will be compressed and when the arms are moved beyond their alined positions the spring will expand to complete the movement of the arms, thus completely shifting the valves. One end of a toggle 36 is rigidly secured to the shaft 29 and the other end thereof is 'pivotally connected with one arm of the bell crank 37, the other arm of which is connected with a rod 38 which functions in a manner to pensing apparatus forms no part of the present invention except in so far as it enters into combination with the-recording mechanism and the. controlling devices therefor, and therefore it need not be described in detail. A full description of a dispensing apparatus of this type will be found in Patent No 1,612,488, granted December 28, 1926 to carbanaro.

Associated with the liquid delivery mechanism is a register adapted to record certain items relating to the liquid delivered, such as ,the number of gallons, or other units, delivered-on each Y delivery transaction and the money value thereof. Preferably the register is of the recording type and is provided with means'for printing a record of the registered items and for issuing a ticketonwhichsaiditemsareprinted. There'g type wheel is a gear 41 which forms p isteritselfisnotapartofthepresentinvention and I have illustrated only suchparts thereof as are n to an understanding of the operation of the invention. The registering mechanism here illustrated comprises a series of type wheels 39 (Figs. 1, 3 and 10) rotatably mounted on the countershaft'm and connected th each of the mechanism for operating that type wheel. The printing m comprises two platens, 42

and 43, here shown as rollers carried by a pivoted frame-44 and so arranged that when the frame is moved in one direction from its normal position the platen 42 will be brought intoprint- .ing relation to the type wheels and when the frame is moved in .the other direction from its normal position the platen 43 will be brought into printing relation to the type Wheels. Separate webs of paper extend about the respective platens and each web is so supported by its platen that it will be moved into contact with the type which are in printing position when that platen is moved into printing relation to the type wheels.- One of said webs becomes a permanent record which is retained in the machine and the record printed on the other web isdetached and issued as a ticket, as is customary in ticket issuing machines. The platen frame 44 is connected by a pitman 45 (Fig. 7) with. a wrist pin 46 carried by a mutilated gear 47 to which is rigidly connected agear 48. The "gear 48 meshes with a or record on the'register preparatory to printing the same is controlled by a movable part of the delivery mechanism in such a manner as to cause a predetermined operation of said means upon the delivery of each unit of liquid. The setting up means for the register may be, connected therewith, to transmit the record thereto, in any suitable manner. In the present mechanism the set-: ting up means comprises mechanism. constituting an accumulator which is disconnected from the register during the delivery of the liquid and after the delivery has been completed is connected with the register and actuated to transfer the' accumulated record 3 thereto. The setting up -2- means as a whole comprises a plurality of sepa; rate devices, there being preferably a separate setting up device for each counter-wheel 39 of the register. Each of these devices includes an accumulating element which may conveniently be in the form of a gear. Connected with each such accumulator gear are various other elements for controlling the operation thereof, each group of elements constituting a gear unit. For the purposes of the present machine I have provided, as shown in Figs. 11, 12 and 13, the two gear units 62 and 63 for the gallons counterwheel, and four gear units, 68; 69, I0 and '11, for the mills, cents, tens of cents and dollar counterwheel.

The several gear units are similar in character. 5-"

Some of them differ slightly in detail from the others. In Fig. 3 I have illustrated the cents gear unit-89, which is typical of the other units. except for minor differences which will hereinamr appear. The gear unit there illustrated :50

comprises a rotatable member52, here shown as a forty tooth gear, (-see Fig. 3), to which a pre-, determined movement is imparted upon the delivery of each unit of liquid by the dispensing apparatus. The, device for imparting this movement to the rotatable member mayconveniently take the form of a pawl, as shown at 53, and, in the present arrangement, a ratchet wheel 54 is rigidly secured to the rotatable member and arranged to be' engaged by the pawl. The gear 52 and the ratchet wheel 54 are rotatably mounted upon a'normally stationary shaft 55 and the pawl 53 is supported by a suitable pawl carrier here shown as an arm 56 pivotally mounted on the shaft 55 and having an offset portion provided with a radial slot 57. A spring 58 acts on the pawl to press the same toward the ratchet'wheel. A lever 59-is pivotally mounted at one end on ashaft 60 and has at its other end a pin 61 extending into the slot 57 of the pawl carrier so that the movement of the. lever 59 about its axis will move the pawl carrier about the axis of the shaft 55 and cause the pawl to operatively engage the ratchet wheel. The ratchet wheel is held against reverse movement by a detent pawl 253 which is actuated by a spring 254 rigidly connected with the gear 52 and ratchet wheel 54 is a four tooth gear 64 (Fig. 6.), which actuates ther transfer mechanism, as will be hereinafter described.

The number of "counterwheels or accumulators 52 will be determined, in part at least, by the'numher and character of the items which are to be registered. In the present machine I have shown means for registering gallons, or units of delivery up to ninety-nine and means for registering money value of the liquid delivered up to nine dollars and. ninety-nine cents. In some localities the price of gasoline is quoted in fractions of a cent, usually in tenths. In order to compute the price where a fraction is involved I have provided a gearunit for registering in tenths of a cent or mills, such a gear unit being shown at 68 (Figs. 11 and 12), \and comprising a four tooth transfer gear 64a and a forty tooth ratchet wheel 54a. As will hereinafter appear the record is not trans ferred to the register in mills and therefore this gear unit does not require the forty tooth counter gear. The cents gear unit, as above described, is shown at 69, and the tens of cents gear unit is shown at 70, the latter comprising a forty tooth gear 52b, a forty tooth ratchet wheel 54b and a four-tooth gear 64b. The dollars gear unit is shown at 71 and comprises a forty tooth gear 520 and a four tooth gear 640 and a forty tooth ratchet wheel 540, which, in this instance serves merely to hold the gear unit against reverse movement. The mills, cents and tens of cents gear units are independently actuated by pawls 53a, 53, and 53b, (Fig. 10), and

levers

59a, 59 and 59b, (Fig. ll), and the amount is transferred from each gear unit of a lower denomination to the gear unit of the next higher denomination by means of transfer wheels 65a, 65 and 65b, mounted on shaft 66 and arranged to be engaged respectively by the four tooth gearsof the three units, and each having connected therewith a transfer gear 67a, 67 and 671), which meshes with the forty tooth gear of the gear unit of next higher denomination. As will'hereinafter appear the several gear units for computing money values are actuated successively so that the count may be transferred gear 64d in the gear unit 62.

The count on the mills gear unit 68 is transferred to the cents gear unit 69 upon the first operation of the mills gear unit, that is, when one mill is registered on the'mills of the gear unit ten mills are transferred to the cents gear unit. Thus the cents gear unit includes at all times, as

a full cent, any fraction of a cent on the mills gear unit. This is preferably accomplished by so locating the teeth of the four tooth gear of the mills gear unit that the first movement thereof, from its initial position, will cause the cents gear unit to be advanced one space or tooth. This arrangement is shown in Fig. 16 'where the teeth four tooth gear 64b of the cents gear unit 69 are in the 9 "position.

For the purpose of setting up the number of gallons two accumulator gear unitsare provided "which is actuated by pawl 53d and lever 59d in the manner above described. The gear unit 63 comprises a forty tooth'gear 52c, a four tooth gear 64c and a ratchet wheel 64b. This gear unit being the tens counter is not operated independently of the unit counter but the count is transferred thereto by means of the four tooth This four tooth gear is arranged to actuate a transfer gear 65d which is rotatably mounted on the transverse shaft 66 and has connected therewith a gear 67d also. loosely mounted on the shaft 66 and meshing with the gear 52c of the gear unit- 63. The transverse gears 65d and 67d have the same 'number of teeth, in the present instance 20, and it will be apparent that upon each quarter rotation of the forty tooth gear 52d of the gear unit 62 the gear unit 63 will be advanced one step or tooth.

A suitable actuating device is provided for impartingmovement to the

pawl actuating levers

59a, 59 and 59b and 59d, and, as here shown, that device comprises a shaft 268 extending parallel withthe shaft .55 which supports the gear units and having rigidly secured thereto a series of

arms

269a, 269. 26% and 26907.. each having a laterally extending stud or roller 270. and the several arms being spaced lengthwise of the shaft 268 to position the same adjacent to the respective pawl actuating'levers 59a. 59, 59b and 59d. Each of these levers is provided with a downwardly extending projection 271 arranged to be engaged by the, stud 270 of the corresponding actuating arm, the rear edge of the projection being inclined so that the stud will act thereon with a cam action and the length of the projection being such that the movement of the lever will impart the'desired movement to the gear operating pawl. In the case of the money value computing gear units the pawl has a movement through an. arc of ninety degrees so that the ,gear unit is correspondingly short, as shown in dotted lines in Fig. 3. The actuating arms for the money value computing gear units are spaced about the axis of the actuating shaft 268 so of the four tooth gear 64a of the mills gear unit 7 68 are in the 1 position while the teeth of the that the several gear units will be actuatedsuccessively.

Means are provided for causing one complete rotation to be imparted to the actuating shaft 5 268 upon the deliveryof each unitof liquid and this complete rotation of the actuating device will cause the pawls for each of the money value.

gear units

68, 69 and IO to be moved through an arc of ninety degrees and will cause the pawl 53d 1 for the gallons computing gear unit 62 to be moved a distance of one tooth. 'Inasmuch as the pawls for the money value gear units move'a uniform distance upon each operation thereof it is necessary to provide some means for so con-- trolling the operation of those pawls that their gear units will be advanced distances corresponding to the price per unit of the liquid so that each operation of the actuating mechanism will add the price of one unit to the gear units and eventuallyto the register. This price setting mechanism may take variousforms and,

in the present instance, I have mounted on the shaft 55, adjacent to each of the gear units 68,

69 and 70, a disk or plate, 72a, 72 and 72b, (see 2 Fig. 5)., which plates are adjustable'about the axis of the shaft. Each plate has peripheral portions of different radial width, as shown at 73 and 74. That portion having the greater radial width, '13, has its edge even with or slightly be- 3 yond the ends of the teeth of the adjacent ratchet wheel 54 and the nose of the pawl 53 is of sumcient width to overlap both the'plate and'the ratchet wheel and consequently when this wider portion of the plate is in line with the pawl the 5 latter will be held out of engagement with the ratchet teeth. That portion of the plate having the shorter radial width has its edge adjacent to the inner ends of the ratchet teeth so that it will not interfere with the engagement with the teeth 40 by the pawl. The plate may be adjusted about the axis of the shaft in any suitable manner but, as here shown, it has a third peripheral portion provided with gear teeth, as shown at '15, and these teeth mesh with a pinion 76 (Fig. 3) rotatably mountedon a shaft '77 so that by actuating the several pinions 76 the pawl controlling plates for the respective gear units may be adjusted to the desired positions. In the present machine the pinions '76 are arranged to be engaged and actuated by the finger of the operator, itbeing understood that the plates are adjusted only when the price per gallon changes. Preferably each pinion '76 has secured thereto an indicator '78 (Fig. 11) which will indicate to the operator the position of the plate. Detents 79 normally engage the teeth of the price setting pinions '16 to hold the same, and consequently the plates, against displacement. It will be apparent, therefore, that by releasing the detent and adjusting the

plates

72a, 72 and 72b of the respective gear units to selected positionswith relation to the ratchet wheels of those units the mechanism may be caused to register. any desired price per unitof liquid on each operation thereof. For ex- .ample, if the price of gasoline is 18 %.cents per gallon the plate 72a of themills gear unit would be @set to cover all but three of the ratchet teeth which are positioned within the limits of'travel of the pawl 53a, the plate 72 for the cents counter would be set to cover two of the ratchet teeth which are positioned-within the limits of travel. 32 the pawl 53 and the plate 72b for the tens of cents counter would be set to cover all but P one ofthe ratchet teeth which are positioned within the limits of travelof the pawl 53b.

Rlgidlysecuredtotheactuatorshaft 268alongside the gear 87 is a second gear 88 identical with the gear 8'1. The two gears may beconnectedonetotheothertocausethemto rotate in unison, and thus causepower to be means of a pinion 88 which is of suflicient width to mesh with the teeth of both

gears

86 and 87 and is movable into and out of mesh with thew gears. As here shown, the pinion 88 is carried by an arm 89 pivotally mounted on the shaft and is moved into and out of..oper'ative engagement with the gears 86 and 8'1 by a mechanism which will be hereinafter described. Sufice it to say here that this mechanism is of such a character that during the delivery of the liquid the actuator shaft is connected with the motor. It may also be noted here that when the actuating de-' vice is disconnected from the motor the latter is connected with the printing mechanism. To this end the gear 51which actuates the platens 42 and 43 meshes with a gear 90 loosely mounted on a shaft 91. Loosely mounted on the shaft 91 alongside the gear 90 is a second gear 92 which meshes withthe driven gear 85. The gears 90 and92aresoarrangedthatwhentheconnecting pinion 88 is moved out of mesh with the

gears

86 and 87 on the actuator shaft it will be moved into mesh with the

gears

90 and 92 for the printing mechanisms The circuit for the otor 81 is controlled by a switch, which as shown in Fig. 8, comprises a stationary contact member 93 and a movable contact member 94, the latter being provided with an extension or finger 95 by means of which it may be actuated. Aswitchactuating lever 96 13c is pivotally mounted on a fixed axis, as shown at 9'1, and has at one end a transverse projection 98 which extends beneath the finger, or extension 95 of the movable switch member and serves to control the position of that switch member. A spring 99 actsonthelever96tomovethesameinadirection which will cause the switch to be closed. Normally this movement of the lever is prevented by a latch 100 having ashoulder 101 which engages beneath the transverse projection 98 on the lever, when the latter is in its elevated position, and retains the switch in its open position. A-

spring 10': holds the latch normally in operative engagement with the lever. A finger 103 on the m5 latch extends into the path of a ing or projection 104 carried by a vertically reciprocatory switch .operatingmembe'r 105 which is provided with 'slots106bymeansofwhichitisslidablymmmted on studs 107. 'ihe switch operating membenlo5 150.v

is held normally in its elevated position by a spring 108 which is connected at one end with the upper stud 107 and at its other end with a stud 109 on the switch operating member. When the operating member is pressed downwardly the lug 104 thereon will actuate the latch against the action of the spring 102 to release the lever 96 and the spring 99 will move that lever about its axis and therebyrelease the switch 95 and permit the latter to close, this being accomplished by the resiliency of the support for the movable contact member. Mounted on the shaft 84 is a cam 110 having a projecting portion or lobe 1 11. The lever 95 has at that end thereof, opposite the projection 98, an upwardly extending nose 112 which is so arranged'with relation to the cam 110 that when the parts are in their normal positions, with the switch open, the nose will lie just behind the canf projection 111 and will be spaced radially beyond the same. When the switch operating member 105 is depressed and the lever 96 released the nose 112 of that lever will move inwardly into contact with the periphery of the cam 110 in the rear of the projection 111. The switch having been closed the motor will operate on the shaft 84 and the cam 110 will rotate in the direction of the arrow and as the shaft completes a single rotation the projecting portion 111 of the cam will force the nose 112 of the lever 96 outwardly thus moving the transverse projection 98 at the opposite end of the lever upwardly to open the switch and to permit the latch 100 to again engage the secured to the lever 96 at the axis thereof is an arm 115 having a nose 116 so positioned that when the parts are in their normal positions, with the switch open, the nose 116 will extend into the recess '114 and will form a stop to prevent the.

rotation of the disk and consequently of the shaft. When the switch controlling lever 96 is released and moves in a direction to close the switch the nose 116 of the arm 115 will move out of the recess in the disk and the latter will be free to rotate but when the cam actuates the lever 96 to restore the parts to their normal position the nose 116 will be again moved into the recess 115 and will stop the movement of the disk at the end of a complete rotation. However, it is not practical to instantly stop an electric motor and I have therefore interposed a slip connection between the motor and the shaft 84. As shown in Fig. 11, the worm gear 83 is carried by a sleeve 117 in which the shaft 84 is rotatably mounted and the end of this sleeve is provided with an enlargement or disk 118 adjacent to the disk 113, which is rigidly secured to the shaft 84 and friction material 119 is interposed between the disks under sufficient pressure to cause the two parts to normally rotate in unisonbut to permit the sleeve to rotate with rel cnto the shaft when the movement of the latter is suddenly checked.

The switch operating member 105* is actuated by a movable element of ihe dispensing appathe switch operating member is' provided at its upper end with a lateral extension or head 120 which, as above described, is actuated-by the shaft 29 of the delivery mechanism upon each operation thereof. Consequently each time the valve mechanism of the dispensing apparatus is reversed the finger 128 will, through the connecting mechanism, depress the switch operating member 105 and cause the motor to impart one complete rotation to the actuating device;

As has been stated, the count which is received by the gear units may be transferred to the registering device in any suitable manner and at any suitable period during the operation of the mechanism but, in the present device, the gear units serve as accumulators and the accumulated count, or tctalized record, is not transferred until the end of the delivery operation. Consequently the gear units are normally disconnected from the register and a connection must be established before the count can be transferred. In the present mechanism I have utilized the

transfer pinions

67a, 67, 67b and 67d as parts of the means for connecting the gear units or accumulators with the register. These transfer pinions are in constant mesh with the forty tooth gears of the respective gear units and I have mounted adjacent to each of these transfer pinions, which are here shown as twenty-tooth gears,

idle pinions

131a, 131, 1312) and 131d, (Figs. 3 and 13) which mesh in intermediate gears 132 which in turn mesh with the respective gears 41 which are connected with the type wheels of the register.

Inasmuch as the gear unit 62 was driven by the actuating pawl to register units of gallons it has no transfer gear in mesh with the gear 52d and I have mounted on the shaft 66 an idle pinion 290, which is in mesh with the gear 52d and an idle pinion 291, which is in mesh with the corresponding intermediate gear 132. (Figs. 12

and 13.) The

pinions

67a, 67, 67b, 67d and 290 are normally disconnected from the

pinions

131a, 131, 131?), 131d and 291 so that the operation of the first mentioned pinions, during the delivery of liquid, does not affect the last mentioned pinions or the register. When the gear units are to be connected with the register the pinions 133, 133a, 133b, 1330 and 133d aremoved into mesh with the respective pairs of pinions on the shaft 66, each pinion, 133, 1330., 133b, 1330 and 133d being wide enough to mesh with both of the other pinions, thereby causing those pinions to rotate in unison and causing any movement of the forty-tooth gears to be transmitted to the corresponding type wheels of the register.

As here shown, the pinions 133, 133a, 1331;, 1330 and 133d are mounted on a shaft 292 carried by arms 134 rigidly mounted on the shaft '77. Rigidly secured to the shaft 77 is an arm135 extending to a point adjacent to the shaft 55 and having at its end a stud 136 extending into a cam groove 137 of a cam 138 (Fig. 7) which is rigidly secured to the shaft 55. The shaft 55 is provided with suitable means, such as a crank 139,,for operating the same and the arrangement of the cam 138 with which a s a stud'or r0l1ei' 121 (Fig. 7) is such that the first movement imparted to the pinions 133, 133a, 1332), 1330 and 133d into mesh with the corresponding-transfer pinicns andthereby establish the connection between the gear units or accumulators and 'the register. The cam groove is so shaped that the pinion will be held in this position until the-shaft operating device has completed its movement and been returned to its initial position. Means are also provided to cause the first part of the movement of the shaft 55 to shift the pinion 88 and thereby disconnect the actuating device from'the motor and connect the latter with the printer. For this purpose an arm 140 is rigidly connected with the arm 89 which carries the pinion 88 and has at its free end a stud141 which travels in a box cam 142, the cam groove being so shaped that the first movement of the cam will shift the pinion and during the remainder of the movement of the cam the pinion will be held in the position to which it has been moved, that is, in a position toconnect the motor with the printer. The type wheels 39 of the register may be reset in any suitable manner. In the present machine they are reset'by restoring theintermediate -gears 132 to their initial positions, and this is accomplished automatically at the end of each printing operation. For this purpose a yoke 190 (Fig. 3) is pivotally mounted on the axis of the .gears 132 and extends across the peripheries of those gears in the paths .of fingers 191 carried by the respective: gears. The yoke is moved in a reverse or resetting direction by a spring 192. When the gears'132 are actuated-to transfer the count to the type wheels the yoke will be moved against the action of the spring a distance equal to the greatest distance traveled by any of the gears and when the connecting pinions 133 are withdrawn and the gears 132 released the yoke will be movedin a reverse direction by the spring and will pickup the fingers 191 of the several gears ahd carry the gears to their initial positions, thus also returning the typewheels to their initial positions. 'A stop 193 is provided to check the movement of the gears 'when' they have reached. their initial positions.

It is desirable that the liquid dispensinga'pparatusshouldbe rendered inoperative during the er of the record and it is preferable that this should be accomplished at the beginning of thetransfer operation. I have therefore provided m'eans wherebythe circuit through the pump operating motor will be broken during the initial movement of the shaft operating device 139.- As shown in Fig. 7, the pump motor switch comprises a fixed contact 143 and a movable contact 144 carried by a resilient arm 145. A crank arm 1461s mounted'on a fixed axis 146a adjacent to the resilient arm 145 near itsfree end a stud 147 on which is mounted. a roller 148, preferably of insulating material, which contacts with the resilient arm 145. Rigidly connected with the arm 140, which actuates the pinion 88, is an arm' 149 having its free end, in-

clined, as shown at 150, and arranged in contact -withthe stud 147 on the arm'l48, the arrangement. being such that when the "arm 140 is actuatedby the cam 142 the inclined ehd of the 7 arm 149 will act'on thcstud14'l and cause the,

roller 148 to'press the movable contact member 144 out of engagement with a fixed contact mem her 143 thus breaking the circuitthrough the pump motor. The arm 149 is retained in a position to maintain the circuit broken lmtil the o'persting device is returned to its i 1,955,004 shaft by its operating device will move the At the end of each delivery transaction the gearunitsareresettosermtherebeingofcourse four zero positions on each forty-tooth gear, and this resetting movement of the gears is utilized to transfer'the count to the register through the connection which has been established. In the present instance, the gear units are reset by continuing their movement in the normal direcrtion of operation, thus causing each forty-tooth gear, when reset, to be moved to a distance equal to the difference between the amount registered thereon and ten. The type wheels of the register are set normally in their zero positions and the connections between the same and the gear unitsaresuchthatwhenthe gearunits are ad-' vanced to complete the movement thereof, and thus reset, the respective typewheels will be rotatedinareversedirectiondistancesequaltothe distances to which the corresponding gear units are moved. For example, if one of the gear units has accumulated a count of eight it will be moved forwardly a distance'of two-teeth in resetting'the same, and this movement when transmitted through the connecting gearing to the,

corresponding type wheel will move that type' wheel in a reverse direction the distance of two teeth, thus'bringing the "8" type into printing position. The four

tooth gears

64a, 64,.64b, 64c, 54d and 64e which form parts of the mechanism for transferringthe count from one gear unit to mother also constitute parts of the re setting mechanism and all the gearunits are therefore provided with these four tooth gears. Cooperating with each four tooth gear is a pawl 151,- the several pawls being in the present instance formed from one piece of metal and being moimted on a rod 152 carried by arms 153 .pivotally moimted on the shaft 55. Means are provided whereby each complete operation of the operating devieel39 for the shaft 55 will move the pawlfi 151 through an arc of ninety degrees. The for actuating the pawls 151 .shouldbeofsuchacharacterthatthepawlswill not impart movement to the gear units until-the connection has been established between the gear units and'the register and after the resetting operation has been completed the operating device shouldhave a slight'movement, after the pawls are' stopped, for the purpose which will hereinafter appear. This may be accomplished in various ways and'in'FlgfB. I have shown one bymeansofwhichthedesired results'msybesecurcd. Asthere shown,'anarm 154isrigidlysecuredtotheshaft 55and asec- 0nd arm 155 is loosely'mounted on-that shaft. A spring 156 is connected at one end with a pin .15'lontheann154andattheotherendwitha of one of-the arms153 but is normally spaced some distance therefrom. When movement is impartedtotheshaft55thit 154willrotate with the shaft and cause the arm 155-to move therewith but-the distance between the pin 158 and the edge of the pawlcarrying arm 1531s such that the

cams

138 and 143 will haveample time tofunctionbefore movement isimpartedto'the pawl carrying arms. After the a.rm 1." 5- has .willbemovedthroughanarcofnmetydegrefi,

andduringthis t theywill pick up the next preceding teeth on thefour tooth gearsand thereby move each gear unit to itlaerogpositioml pawl supporting armldtengaga'the picked up the pawl carrying arm-153 the pawls' stop 159 the shaft 55 and arm 154 may continue to move in the same direction due to the yielding of the spring 156, this additional movement being suflicient to cause the motor to operate the printing mechanism. This lattercperation is brought about by means of an arm 160 (Fig. 7) rigidly secured to a shaft 161 and having a pin 162 arranged in the path of a part or edge 162a of the cam 142'and so arranged that it will be engaged by that part of the cam just before the cam completes its movement. Rigidly connected with the shaft 161 is a slotted arm 163 which engages a pin 164 on the link 125 forming part of the switch operating mechanism. Consequently after the count has been transferred from the gear units to the register, by the resetting of the gear units, the further movement of the operating device 139 will cause the circuit to be closed through the motor and the record printed.

Inasmuch as the mechanism.must be manually operated to bring about the printing of the record it is desirable that some means be provided to require the operator to print the record. 1 o. the present mechanism I have provided means whereby the accumulation of a money value of an excessive'amount on the gear units will cause the circuit through the pump motor to be broken and will prevent the closing of that circuit until the record has been printed. This, of course, does not force the operator to print a record of each transaction but he must ultimately print the accumulated record and if the records printed are abnormal an inspector will know at once that each transaction record has not been printed. The.

means for accomplishing this comprises an arm 165 rigidly connected withthe switch operating mechanism 146 and having a laterally extending projection 166 arranged in the path of an arm 167 mounted on the shaft 77 and having connected therewith an arm 168 arranged to be actuated by a cam169 rigidly connected with the dollars gear unit. This cam is a four lobe cam and is so arranged with relation to the gear unit that when the dollars gear passes from the eight to the nine position one of the lobes of the cam will engage the arm 168 and impart sufiicient movement thereto to cause the switch to be opened, thus interrupting the operation of the motor whenever the amount of $9.00 has been accumulated without the record being printed.

Each lobeof the cam has a dwell of suflicient length to hold the switch in its open position until the gear unit has been moved to its open or zero position. Inasmuch as the dispensing mechanism is inoperative the only way in which the gear unit can be moved to that position is by operating the resetting mechanism and causing the record to be printed. When the gear unit is reset to.zero the arm 168 will be released and the pump motor switch will close. A full stroke mechanism is provided to prevent the operator from moving the resetting mechanism far enough to release the arm 168 and then returning the'same to its initial position without closing the switch through themo.or which operates the printing mechanism.

The full stroke mechanism for forcing the operator to complete the movement of the operating device 139 and the shaft 55 in one direction before he can reverse that movement may take various forms. As shown in Figs. 11 and 14, I have rigidly connected with the shaft 55, adjacent to the operating handle 139, two

segments

170 and 171 having opposed ratchet teeth. Pivotally mounted on a stud 172, mounted on a fixed sup- 'end a hook shaped portion 177 adapted to engage over a stud 178 on the adjacent pawl to hold'that pawl in its inoperative position. This frame ordinarily swings free on the shaft 55 and one of the segments is provided with

studs

179 and 180 arranged on opposite sides of the frame, so that one or the other of these studs will engage the frame and impart movement thereto as the operiating device completes its movement in one direction or the other. The movement of the frame is limited by projections 181 extending downwardly on the opposite sides of the pawl supporting stud 172. Each toothed segment is provided with a cam 183, these cams being so located with re- ,iation to the respective segments that as the operating device approaches the limit of its movement one of the cams will engage the pawl which is in operative engagement with its segment and move the same out of engagement therewith. For example, as shown in Fig. 14, the pawl 173 is in engagement with the segment 170 and when the operating member 139 is moved to the right and approaches the limit of its movement in that direction the earn 183 of the segment 170 will engage the pawl 173 and force the same out of engagement with the segment. Immediately following the movement of the pawl to its inoperative position the stud 180 will engage the swinging frame, 1'76 and move the. hook shaped portion 177 thereof above the stud 178 on the pawl, thereby locking this pawl in its inoperative position. .At the same time the hook shaped portion 177 on the other edge of the swinging frame will be moved out of engagement with thestud 178 on the pawl 174, thereby releasing that 'pawl and permitting it to be moved into engagement with the toothed segment 171. As the'operating handle is moved in a reverse direction, that is to the left in Fig. 14, the pawl 174 will hold it against reverse movement until the 'cam 183 of thesegment 171 reverses the pawls in the manner above described.
