Definitions
- This invention relates to presettable registers table register capable of controlling the repeated operations of a device orsystem for a series of like predetermined registrations without requiring to be reset; the'invention being particularly adapted to control the operation of dispensing systems or the like where batch" operation is desired.
- One of the objects of the invention is to con-
- a register which may be preset to indicate a predetermined amountto be registered and which operates at the termination of the predetermined registration to automatically condition itself in preparation for the initiation of a succeeding registering operation.
- Another object of the invention i to construct predetermined amount'to be registered and which operates to indicate both the number or amount actually registered and the number-or amount of the predetermined registration still to be registered, the register being so constructed that at the end of the predetermined registering operation it automatically conditions itself preparatory to the initiation of a new registering operation.
- Another and more specific object of the invention is to construct a register provided with dual counting devices wherein one of the devices may be preset at a predetermined registration while the other device is in zero position, the register being so-constructed and arranged that the dual counting devices operate in opposite directions, the relative operation of the dual counting devices-being automatically reversed upon the termination of the predetermined registration in preparation for the initiation of a new registering operation.
- a further object of the invention is to construct a register which is adapted to control the operations of a device or system which .will automatically cause the operation of such device or system, as the case may be, to cease upon the termination of a'predetermined registration, and
- a register capable of being preset to indicate a registering indicators are so arranged that either duration without requiring to be reset or readjusted.
- a further and more specific object o! the in vention is to provides. register adapted to control the operation of a dispensing system where batch delivery is desired which is capable of being preset to cause-the dispensing operation to'cease when a predetermined amount of the material being dispensed has been delivered, and
- An additional object of the invention is to provide my novel predetermined auto stop register with a signalling means which operates automatically to indicate which of the dual counting devices thereof is registerin the additive count.
- Another additional object of the invention is to provide my novel predetermined auto stop register with an emergency tripping device whereby the .operation of the device or system being (ontrolled may be'manually caused to cease at any stage during an operation.
- Still another additional object of the invention is to provide my novel predetermined auto stop register with a quantity totalizing counter and/ or a batch totalizing counter.
- I call dual registering indicators the others comprising a quantity totalizing indicator and a batch totalizing indicator.
- Th dual one may be preset to indicate a predetermined registration while the other is in zero position.
- the dual indicators are then driven by the device or system to lie-controlled through a novel reversible clutch connection.
- the indicator which is in zero position at the initiation of a registering operation' operates to indicate an additive count or registration while the preset indicator operates to indicate the amount of the predetermined registration or setting which is yet to be registered, the preset indicator moving retrogressively during the operation to its zero position whereupon the predetermined registration is terminated.
- a cam operated tripping and reversing mechaclutch to be actuated so as to reverse the relative operating relation of the dual indicators in preparation for the initiation of a new registering operation, and the batch totalizing counter to be actuated'to register a unit operation.
- the actuation oi the reversible clutch mechanism in reversing the relative operating relation of the dual indicators connects the previous additive registering indicator as a preset indicator and the previous preset indicator, which now indicates zero, as an additive registering indicator, no resetting or presetting of the dual indicators being necessary for a repeated operation of the same amount. If the next operation is for a registration different from the last, a hand operated mechanism is so arranged that it may be actuated to adjust the indicator which is in the preset position to indicate the predetermined amount of the next operation. If, however, the same predetermined registration is desired for the next operation, the only step necessary is the restarting of the device or system being controlled which may only require the mere pushing of a control button or the actuation of a lever.

3 Claims.
This invention relates to presettable registers table register capable of controlling the repeated operations of a device orsystem for a series of like predetermined registrations without requiring to be reset; the'invention being particularly adapted to control the operation of dispensing systems or the like where batch" operation is desired.
One of the objects of the invention is to con-,
struct a register which may be preset to indicate a predetermined amountto be registered and which operates at the termination of the predetermined registration to automatically condition itself in preparation for the initiation of a succeeding registering operation.
Another object of the invention i to construct predetermined amount'to be registered and which operates to indicate both the number or amount actually registered and the number-or amount of the predetermined registration still to be registered, the register being so constructed that at the end of the predetermined registering operation it automatically conditions itself preparatory to the initiation of a new registering operation.
Another and more specific object of the invention is to construct a register provided with dual counting devices wherein one of the devices may be preset at a predetermined registration while the other device is in zero position, the register being so-constructed and arranged that the dual counting devices operate in opposite directions, the relative operation of the dual counting devices-being automatically reversed upon the termination of the predetermined registration in preparation for the initiation of a new registering operation.
A further object of the invention is to construct a register which is adapted to control the operations of a device or system which .will automatically cause the operation of such device or system, as the case may be, to cease upon the termination of a'predetermined registration, and
to automatically repeat such control for any series of successive operations of like quantity or and more particularly to an automatic preset- .a register capable of being preset to indicate a registering indicators are so arranged that either duration without requiring to be reset or readjusted.
A further and more specific object o! the in vention is to provides. register adapted to control the operation of a dispensing system where batch delivery is desired which is capable of being preset to cause-the dispensing operation to'cease when a predetermined amount of the material being dispensed has been delivered, and
which will automatically repeat such control by causing the dispensing operation to cease for each successive "batch" whenever such predetermined amount has been delivered.
An additional object of the invention is to provide my novel predetermined auto stop register with a signalling means which operates automatically to indicate which of the dual counting devices thereof is registerin the additive count.
Another additional object of the invention is to provide my novel predetermined auto stop register with an emergency tripping device whereby the .operation of the device or system being (ontrolled may be'manually caused to cease at any stage during an operation.
Still another additional object of the invention is to provide my novel predetermined auto stop register with a quantity totalizing counter and/ or a batch totalizing counter.
The foregoing objects and others ancillary thereto are accomplished by my invention by constructing a register with four sets of counters, two of which I call dual registering indicators, the others comprising a quantity totalizing indicator and a batch totalizing indicator. Th dual one may be preset to indicate a predetermined registration while the other is in zero position. The dual indicators are then driven by the device or system to lie-controlled through a novel reversible clutch connection. The indicator which is in zero position at the initiation of a registering operation' operates to indicate an additive count or registration while the preset indicator operates to indicate the amount of the predetermined registration or setting which is yet to be registered, the preset indicator moving retrogressively during the operation to its zero position whereupon the predetermined registration is terminated. Associated with the dual indicators is a cam operated tripping and reversing mechaclutch to be actuated so as to reverse the relative operating relation of the dual indicators in preparation for the initiation of a new registering operation, and the batch totalizing counter to be actuated'to register a unit operation.
The actuation oi the reversible clutch mechanism in reversing the relative operating relation of the dual indicators connects the previous additive registering indicator as a preset indicator and the previous preset indicator, which now indicates zero, as an additive registering indicator, no resetting or presetting of the dual indicators being necessary for a repeated operation of the same amount. If the next operation is for a registration different from the last, a hand operated mechanism is so arranged that it may be actuated to adjust the indicator which is in the preset position to indicate the predetermined amount of the next operation. If, however, the same predetermined registration is desired for the next operation, the only step necessary is the restarting of the device or system being controlled which may only require the mere pushing of a control button or the actuation of a lever. v

For purposes of illustration, I have shown in Figure 1 an embodiment of my invention enclosed in a casing l2 in combination with a fluid measuring or dispensing system comprising a meter l3 and a flow control valve M. The meter l3 may be of any desired type which upon the passage of liquid or other fluent material therethrough operates to transmit a shaft movement corresponding to the quantity of the material passed therethrough. The valve I4 is of the self closing type, the closing of which is controlled by the register as hereinafter described. The I register itself comprises dual registering indicators I5 and I 5 which are exposed through windows in the face of the casing I2. A glass or other transparent plate I! extends over the face of the casing and prevents dust or moisture from entering through the windows. Associated with the dual indicators is a signalling or disclosing device l8 which operates to indicate or otherwise render it apparent which of the dual indicators is operating as the additive counter during a registering operation. Exposed through other windows are also a quantity totalizing counter l9 and a batch totalizing counter 20.
The mechanism for driving the dual indicators '5 and I8 is best shown in Figures 2, 3 and 4.
The meter shaft 2| is coupled by means of a shaft 22' to a gear compensating mechanism indicated generally at 23 which is adapted to callbrate the registering device to coordinate it with the particular meter with which it is associated in order to accurately register the quantities of liquid flowing through the meter. This compensating mechanism is also adapted to enable adjustments to be made to insure accurate registration when measuring the flow of fluids of different viscosities, or to enable correction for changes in the viscosities and/or temperature of the particular fluid being. measured. A gear compensating mechanism of this type is fully disclosed in the patent to W. L. Marden, No. 1,970,526, issued August 14, 1934.
A shaft 24 operatively connects the compensating mechanism 23 with a reduction gear train 25 which is provided for reducing the relatively high operating speed of the meter shaft to a rate suitable for operating the register and associated tripping mechanism.
A register drive shaft 25 is driven by the reduction gear train 25 through a gear 28 carried by the shaft 26. A worm 30 mounted on the upper portion of the vertical shaft 25 drives a worm gear 32 secured to a horizontal shaft 33 upon which a five lobe cam 34 is axially mounted by means of a sleeve 36. The horizontal shaft 31 which is supported in part bythe frame member 31 supports a spur gear 38 which meshes with the peripheral gear teeth 40 of a crown gear 42 carried by a shaft 43. k
Mounted on two spaced struts 44 and 45 of the frame-like housing 48 of the register are two bearings 41 and 48. A reversing shaft 49 is rotatably and slidably mounted within the bearings 41 and 48. .Rotatably mounted on the bearing 41 is a clutch gear 50 which is adapted to mesh with the crown gear 42. A like clutch gear 5| is rotatably mounted upon the bearing 48 for meshing engagement with the crown gear 42 at a point diametrically opposite to the point of engagement of the clutch gear 5|]. The engaging relation of the clutch gears- 58/ and 5| with the crown gear 42 at diametrically opposite points causes these gears to rotate in opposite dlrections.
In order to selectively transmit the motion of the clutch gears 50 and 5! to the reversing shaft 49, each of the gears 50 and 5| is provided with a laterally projected clutch pin 52 and 53, respectively. A circular clutching element 54 secured to the reversing shaft 49 between the bearings 41 and 48 is provided with a plurality of laterally extended fins and 58 on opposite sides adjacent the peripheral edge thereof. These laterally extended fins 55 and 55 are adapted to engage the pins 52 and 53 depending on the position of the clutching element 54. As shown in Figures 4 and 5, one of the fins 55 is in engaging relation with the pin 52 so that the clutching element 54 is adapted to be driven by the clutch gear 50. The fins 55 and 56 are staggered with respect to each other so that one of the pins 52 or 53 may be effectively disengaged and the other engaged by a quick shifting movement of the clutching element 54 without theyoccurrence of any appreciable relative movement between the driving clutch gears 50, 5| and the driven clutching element 54.
The dual registering indicators l5 and. I6 may comprise any desired number of counter wheels or drums, three each being shown for purposes of illustration. Referring to Figure 5, the indicator I consists of a units wheel 88, tens wheel 8| and a hundreds wheel 62, each rotatably mounted on a shaft 64. The numeral wheels of the indicator I5 are driven by the reversing shaft 49 by means of an elongated pinion 65 carried by the shaft 49, an idler gear 66, and a gear 81 car ried by the sleeve 88 which is rotatably mounted on the shaft 64. The sleeve 68 is provided with a disk 69 which slidably engages the peripheral side edge of the units wheel 68, and which pivotally supports a pair of L-shaped pawls l8 and II. The pawls I8 and II are urged into engagement with slots I2 formed on the inner surface of the units wheel 88 by a spring I5 sufficiently strong to maintain the pawls I8 and II in driving engagement with the slots I2 for transmitting movement for both directions of rotation of the sleeve 88 to the numeral wheel 68.
The left side portion of each of the numeral wheels 68, 6| and 62, as viewed in Figures 2 and 5, is provided with a control disk I8 which has a cut out portion or notch 11, the purpose of which is described in detail hereafter. Contiguous the control disk I8 on the units wheel 88 are the usual lock disk. and mutilated gear I8 and I9, respectively, which operate the usual transfer pinion 88 for moving the tens wheel 8| through one tenth of a rotation for each complete rotation of the units wheel in accordance with the Geneva transfer movement. The gear 8I which is associated with the tens wheel GI and which meshes with the transfer pinion 88 may have driving engagement with the tens wheel by means of pawls and slots identical to those by which the disk 69 drives the units wheel, it being recognized, however, that thegear 8| may be' directly-secured to the tens wheel for the purregistration, a,-spline 82 is provided in the shaft 84. A pawl 84 is mounted upon the inner side of the units wheel 68 and is urged against the shaft 64 by means of a spring 85. The tens and hundreds wheels 8| and 62 are not provided with.
pawls for engagement with the spline 82, their movement for both the presetting and the regis- 98 may then be actuated to rotate the shaft 64,.
the spline 82 thereof engaging the pawl 84 to move the units wheel 68 and the associated numeral wheels GI and 62 through the Geneva transfer movement to the setting desired.
The presetting movement of the numeral wheel 68 by the operative engagement of'the pawl 84 and the spline 82 is permitted by the pawl and ratchet connection between the numeral wheel 68 and the disk 89. In this connection it may be added that subtractive or counterclockwise movement of the numeral wheels 68, GI and 82, as viewed in Figure 10, will cause the pawl 88, to rotate the shaft 64. This resulting movement of the shaft 64, however, is of no consequence, since the shaft is normally free to idle. This is also true of the shaft 91. 1
The lower registering indicator I8 is of a construction identical with that of the upper reg- 4 istering indicator I5, it being driven by the pinion which meshes with a gear 92 carried by the sleeve 93. The units wheel 94 of the indicator I6 is driven from the sleeve 93 by a pawl and ratchet connection identical to that illustrated in connection with the numeral wheel 88. The numeral wheels of higher order of the indicator I8 are driven from the units wheel 94 by the usual Geneva transfer movement which includes the transfer pinions 85.
The registering indicator I6 is adapted to be preset in the same manner as the registering indicator I5, the manually actuated shaft 89 being capable of moving the gear 81 into meshing engagement with the gear 96 carried by the shaft 91 upon which the registering indicator I6 is mounted.
The reversing and tripping mechanism which is actuated by the predetermined operation of the dual registering indicators I5, I6 and the movement of the five lobe cam 34, is best illustrated in Figures 2, 3, 4, '7, 8 and 9.
A'cam actuated lever 98 is pivotally mounted on a bevelled bearing 99 carried by a stationary shaft I88 and provided with a laterally extended cam roller I82 adapted to engage the lobes of I the cam 84 when the lever 98 is moved into an engaging position therewith, the lever 98 being biased to a non-engageable'position by a spring I83. The initial movement of the lever 98 is controlled by one of the indicators I5 or I6 through a bell crank member I88 or I81, as the case may be, the latter being pivotally mounted. on stationary shafts I84 and I85, respectively. A plurality of rollers I88 are rotatably mountedon a shaft I89, carried by the bracket-like arm II8 of the bell crank member I86, for engagement with the control disks I8 associated with the numeral wheels 8ll, 6| and 82 of the registering indicator I5. A plurality of rollers III are likewise rotatably mounted on the lower arm of the bell crank member I81 for engagement with the control disks associatedwith the numeral wheels of the registering indicator I6. Each of these bell crank members are urged by means of springs I I2 and H8 to cause the rollers I88 and III to bear in riding relation against their respective control disks. I
The vertically extended arms H4 and H5 of the bell crank members I88 and I81, respectively, are positioned to engage the side of the cam actuated lever 98. When all of the numeral wheels of one of the dual indicators 15 or I6 reach or enter-zero position, such as illustrated by the position of the indicator Hi, the notches ll of each of the controlling disks [8 associated with the numeral wheels of the zeroizing indicator -also enter alignment, whereupon the associated rollers tend the move therein causing the vertical arm of the respective bell crank to swing the lever 98 into engaging position with the cam 34. Referring particularly to the indicator I 6. as the notches of the control disks thereof come into alignment, the rollers III are urged into the notches causing the bell crank I81 to rotate in a counterclockwise directionasviewed in Figure 3, thereby moving the cam actuated lever 98 to a position where the laterally extended roller I82 overlies the cam 34. As the cam 34 revolves, one of the lobes thereof will engage the roller I82 and pivot the lever 33 in a clockwise direction, as viewed in Figure 7, about the shaft I00. A latch member IIG, which is pivotally mounted on the shaft I adjacent the cam actuated lever 38 is provided with a laterally extended lug I H which rides on the lever 33. The clockwise movement of the lever 33, therefore causes the latch member II6 to also move and trip a latch engaging lever II8, whereby the operation of the device or system being controlled is stopped.
The spring I03 previously described in connection with the lever 33 may be dispensed with by providing a positive connection between the lever 90 and the bell crank members I03 and I01. Such a positive operating-connection is illustrated in Figure 11. The vertically extended arms II4a and H5!) of the bell crank members I060. and I0Ib, respectively, are pivotally connected at IIS and I2I to the opposite ends of a link I23 having an elongated slot I25 adapted to receive the free end of the lever 98. When the indicator I6, for example, reaches zero position, the tension of the spring I I3 causes the rollers II I to move into the corresponding notches T1 of the associated control disks I6, thereby rotating the bell crank I0'Ib counterclockwise. The counterclockwise movement of the bell crank arm I I5b causes the slotted link I23 to alsorotate counterclockwise about the pivot connection I I9 and move the lever 98 to the left where the roller I02 thereof is adapted to be engaged by the meter driven cam 34 for tripping the latch elements III; and H8. When the indicator I5 reaches zero position in a succeeding operation, the bell crank arm M411 is caused to move in a clockwise direction to rotate the link I23 clockwise about the connection I2 I, thus moving the lever 98 again to the left similarly as when the indicator It moves to zero position. The
' initial actuation of the units wheel upon initiation of a succeeding operation causes the rollers I08 or III, as the case may be, to move out of the notches 11 of the associated control disks I6 and causes the link I23 to be returned and the lever 98 retracted from its cam engaging position.
For the purpose of reversing the driving direction of the shaft 49, and therefore the operating direction of'the dual indicators I5 and I6, a clutch actuating member I20 is pivotally mounted on a shaft I22 by an integral sleeve I24. The upper portion of the clutch actuating member I20 is provided with a laterally supported roller I25 which operatively engages the end flanges I21, I28 of a sleeve I29 carried by the reversing shaft 49. A four cornered cam I30, the side edges of which are curved inwardly between the four corners thereof, is carried by a shaft I32. A pair of laterally supported rollers I34 and I35 are so located on the clutch actuating member I20 that they engage the peripheral edge of the cam I30 at points about 135 degrees apart, one of the rollers riding on the low portion of a side edge of the cam and the other on a corner portion thereof. Secured to the shaft I32 to the left of the cam I30, as viewed in Figure 6, is a ratchet wheel I40 by which the cam I30 is driven.
The latch lever I II which is adapted to engage the latch member I I3 is rotatably mounted on the shaft I32 adjacent the ratchet wheel I40. The lever III! is provided with a laterally extended arm I, which pivotally carries a pawl I42 arranged to engage the teeth of the ratchet wheel I40. The latch lever I I3 may be urged in a clockwise direction, as viewed in Figure 7, against the latch II6 by any appropriately located spring or other biasing means. In the illustrated embodiment of the invention, the spring I43 of the seli' closing valve I4 is utilized for this purpose. When the latch H6 is rotated in a clockwise direction by the cam actuated member 33, the latch lever I I8 is released and, due to the compression of the valve spring I43, the lever I I3 is caused to rotate clockwise to a position indicated by the broken lines in Figure 7.
The clockwise movement of the lever I I0 causes a rotation of the shaft I32 and the four cornered cam I 30 carried thereon by the engagement of the pawl I42 with the ratchet wheel I40. For each clockwise movement of the lever Hi, the four cornered cam I30 is moved through 45 degrees causing the engaging rollers I34 and I35 to reverse their respective positions on the high and low portions of the cam I30, thereby pivoting the member I20 in either a clockwise or counterclockwise direction, as viewed in Figures 2 and 5, depending upon the relative positions of the rollers I34, I35 on the cam I30 at the beginning of the latch tripping movement. In the position illus-- trated, the movement. of the clutch actuating member I20 would be in a clockwise direction. This movement of the member I20 would operate to move the shaft 49 and the clutch element 54 to the right, thereby disengaging the clutching element 54 from the clutch pin 52 and bringing it into clutching engagement with the projected pin 53 carried by the gear 5|. The next rotation of the four cornered cam I30 through another 45 degrees would cause the clutch actuating member to pivot in a counterclockwise direction, thereby reversing the engagement of the'clutching element 54 back into engaging relation with the projected pin 52 carried by the gear 50.
The reversing movement of the member I2. is given a snap action by means of a spring urged toggle member I44 which pivotally engages a conical recess in the surface of a laterally projected lug I45 carried on the member I20. The upper end of the member I44 is slidably held by an eye member I46 carried by the end of the stationary shaft I00. A spring I41 coiled about the member I44 between the eye member I46 and the conical head I43 of the member I44 provides the necessary tension. As the member I20 is moved across dead center, the spring urged member I44 operates to snap the moving member I20 to its new position. This snap action is repeated in the opposite direction when the member I20 is returned.
The device or system to be controlled by the predetermined operation of the dual indicators I5 and I6 is operatively connected to the latch arm I I8. In the illustrated embodiment, a rod I4! is shown pivotally connecting the control lev'er I50 of the flow control valve I4 to the lever Ill. A bracket member I52 mounted on the flow control valve pivotally supports the lever I50. A roller I54 carried by the lever I50 is adapted to engage the valve stem I55 upon a counterclockwise movement of the lever I50 to actuate and hold the valve I4 in open position. Clockwise movement of the control lever I50 caused by the tripping of the latch lever II8 permits the valve I4 to automatically close, thereby terminating the flow of liquid through the meter I3.
Any appropriate signalling means may be provided to indicate which of the dual indicators II and I3 is operatively connected to register the positive count. In some cases it may be desirable to provide a shutter arrangement operable at the initiation of each registering operation to expose the numeral wheels of the indicator connected to register th particular operation. However, in the embodiment illustrated (Figures 1 and 5) the signalling device I8 is shown as comprising a signal plate I60 located between the indicators I5 and I0 and connected by a link IOI to a laterally extended arm I50 carried by the clutch actuating member I20. The signal plate I60 is provided with two sets of arrows, I62 and I63, each setpointing in the opposite direction and spaced from each other. In each position, one set of the arrows I62 or I03 will be exposed at the window I! pointing toward the registering this operation,
indicator which is operatively connected to indicate an additive registration. When the driving connection of the clutch element 54 is reversed, the signal plate I00 is at the same time shifted to expose the other set of arrows indicating that the operative connection of the dual registering indicators has been reversed and that the next additive registration will be registered on the indicator to which the exposed arrows point. While a signalling arrow has been provided for each numeral wheel of the dual indicators I5 and I0, it is recognized that one arrow only for each of the dual indicators I5 and I0 would sufiice and that other forms of signalling or disclosing means may be subst tuted therefor and still be within the purview of my invention.
In order to insure the presetting of only the indicator which is properlyconnected for presetting purposes, the clutch actuating member I is so des gned and positioned that the manually actuated gear 01 is prevented from meshing with the gear carried by the shaft of the indicator which registers zero. More specifically, a I
roller I64 is provided on an arm of the member I20 and is adapted to overlie the gear 90 when the indicator I6 is .in zero position, thereby preventing the gear 01 from being brought into meshing engagement with the gear 90. The
gear 01, however, may be brought into meshing engagement with the gear 80 for the purpose of presetting the numeral wheels of the indicator I5 to indicate the predetermined amount or quantity to be registered during the subsequent regbeing moved to permit engagement of the gear 01 with the gear 90. In this position, the indicator I6 may be adjusted to indicate a different predetermined registration or it may be left undisturbed if it is desired to repeat the amount of the preceding operation.
The operation of-my novel automatic presettable register when used with a fluid dispensing system is as follows:
Assuming that the indicator I0 has been preset to indicate 321 gallons or other unit of the material to 'be measured, the dispensing operation may be initiated by the actuation of the control lever I50 in a counterclockwise direction to the position shown inFigure 1, whereby the valve stem I 50 is depressed to open the flow control I valve I4 and the lever III moved into latch engagement with the latch member H0.
42 through the medium of gears 32 and 30. The clutch gears 50 and 5| are rotated in opposite directions by the crown gear 42. The clutching element 54 is driven by the engaging pin 52 of the clutch gear 50 to rotatethe shaft. and the driving pinion 05. I The idler gear 66 enables the driving pinion 05 to drive the indicators I5 and I6 in the opposite direction, the indicator I5, for being driven to indicate the amount of predetermined registration actually registered; the indicator I0 being driven to indicate the amount of the predetermined registration yet to be registered.
Just prior to the termination of the predetermined registration, the notches ll of the control disks I6 associated with the dual indicator nearing zero position, begin to come into alignment thereby permitting the corresponding rollers I00 or I I I, as the case may be, to be moved therein with a resultant rotation of the bell crank member upon which the rollers are mounted. In the present operation the indicator I6 will be the one approaching zero position, since it was the indicator assumed to be preset at the reading of 321 units; As the notches II of the control disks 16 associated with the numeral wheels of the indicator I0 approach alignment, the bell crank I0I will rotate clockwise, as viewed in Figure 3, causing the arm H5 to shift the cam actuated lever 00 to the left, whereby the roller I02 is brought into a position overlying the cam 34. While in this position, the roller I02 will be engaged by a lobe on the meter actuated cam 34 causing the member 98 to pivotupwardly about the shaft I00. The upward movement of the member 90 in turn causes the latch II6 to be pivoted in a clockwise direction, as viewed in Figures 2- and 7, by engagement with th overlying lug II! to disengagethe latch lever Il0.
Upon the disengagement of the latch lever H8 from the latch Hi, the compression of the 'valve spring I43 causes each of the levers I50 and III! to swing clockwise as viewed in Figures 1 and '7, respectively, whereby the valve I4 is closed and the foiir cornered cam I30 rotated 45 degrees through means of the pawl and ratchet connection I40, I42. The partial rotation of the cam I30 through 45 degrees actuates the clutch actuating member I20 to simultaneously shift the signal plate I and-the clutch element 54 to their reversed positions. in the controlling disks I0 are so positioned with respect to the numeral wheels that the flow control valve is adapted to be fully closed, with the reversing operation snapped to completion, by the time the numeral wheels of the dual indi- N cators indicate the te nation of the predetermined registration, e indicator I5 displaying a reading of 321' while the previously preset indicator I0 registers zero. As shown in Figures predetermined registering operation by the mere is driven bytheyshai't 24 through the medium of actuation of the ,lever I50 to open the flow control 'valve I4.
For the purpose of stopping the device or system being controlled during a' registering operation, I have provided an emergency tripping element I05 which may be actuated by themere pushing of an exposed button I00. This emergency tripping'element I05 comprises an elonl The notches II gated flat member with one edge thereof beveled at I61, as shown in Figure 4, to engage a lug I68 on the latch HE. A slot III) is provided In the strut 45 of the fr he structure to slidably support an edge of the tripping member I65 so that when the member is moved inwardly th bevelled edge I61 will be caused to force the latch III; to pivot in a clockwise direction and release the lever N8, the tripping member I65 being retracted by a spring I'II. As previously described, the releasing of the lever IIB from the latch member Il6 permits the valve It to close and immediately stop the flow of liquid through the meter I3.
The quantity totaller I9 comprises a series of numeral wheels as illustrated in Figure 2. The quantity totalizer is driven from the shaft 26 by the worm I12 and the train of gears I13, I'll and I15. The unit or numeral wheel I16 of lowest order of the quantity totalizer is driven directly from the gear I15. The remaining number wheels, each of which are of a succeeding higher order, are driven from the numeral wheel I16 by means of the usual Geneva transfer move ment including transfer pinions I".
The batch totalizer 20, which may or may not be of the resettable type, is driven by a crown gear III! secured to the shaft I32 to the right of the four cornered cam I30 as viewed in Figure 6. An inter-engaging idler gear I82 drives the units wheel of the batch totalizer 20 from the crown gear IN, the numeral wheels of higher order being driven by the units wheel through the usual Geneva transfer movement.
The driving ratio of the gears I80, I82, and I84 is such that for each rotational movement of the cam I30 through a distance of 45 degrees, the batch totalizer is actuated to register one unit of operation.
It will be recognized from the foregoing description that I have invented a novel register which may be preset to indicate a predetermined amount to be registered, and which operates at the termination of the predetermined registration to automatically condition itself preparatory to the initiation of a subsequent registering operation without the necessity of a resetting operation; that theregister operates to indicate both the amount actually registered and the amount of the predetermined operation still to be registered at all times during the operation; and that the register is capable of controlling the operation of a device or system for a series of like predetermined operations; the register operating to cause the operation of the device or system, as the case may be, to cease upon the termination of a predetermined operation, and to automatically repeat such control for any series of successive operations of like quantity or'duration without requiring to be reset or re-adjusted.
Although I have shown and described only one specific embodiment of my invention, I am fully aware that many modifications thereof are possible and that the novel register thereof is capable of use for the the purpose of controlling operations of devices or systems quite different from the dispensing system disclosed. My invention, therefore, is not to be restricted except insofar as is necessitated by the prior art and the scope of the appended claims,
