Specification of Letters Patent.

Application led April 20, 1912, Serial No. 692,047. Renewed September 8, 1915. Serial No. 495613;

To all lwhom t may concern.'

Be it known that I, HoMER J. P. HAMP- TON, a citizenof the United States, and resident of Jersey City, in the county of Hudson and State of New Jersey,have invented certain new and useful Improvements in Registers, of which the following is a specification.

My invention relates to improvements in registers, and has particular reference to registers commonly called taximeters for registering the distance traveled, the time consumed, and the amounts payable for the service.

One of the objects of my invention is to provide improved means to permit the stepby-step forward rotation of one or more of the numbering or indicating wheels for a complete rotation, vand the returny of said wheel to normal at the termination of any complete rotation of said wheel, and. likewise the return of said wheel to normal at the termination of any incomplete rotation thereof, whereby such wheel may continue to indicate units, tens, or the like, as required, and will be automatically returned to normal at the termination of each complete rotation, as stated, Without unduly winding a spring th'at restores the wheel to normal.

Further objects of my invention are to cause proper registration of various items, not only of the initial amounts to becharged, but the complete charge for mileage during pay service, thecharge for time service, for' extras, and the like, when my invention is used as a' taxim'eter.

My invention comprises novel details of improvement and combinations of parts that will be more fully' hereinafter set forth and then pointed out Ain the claims.

Reference is to be had to the aocompany-` ing drawings forming part hereof, wherein,

Similar numerals of reference indicate corresponding parts in the several views.

The numeral 1 indicates a suitable frame or casing for the mechanism, in which is suitably journaled a main driving shaft 2, which may be rotated step by step in any suitable manner. For this purpose I have shown said shaft provided with a ratchet 3 engaged by a spring-pressed stop paw] 4, and actuated by a pawl 5 carried by rock arm 6, shown pivoted upon casing 1 at 7, see Fig. 1. Arm 6 may be rocked by any suitable means operated in'any wellknown manner from the road wheels of a vehicle or other driving part, as by a liexible shaft to be connected with rock arm, as ley-means o f a link `6, Fig. 1. In the arrangement illustrated I have provided means for-causing shaft 2 to rotate a desired distance, say, for instance, two teeth of the ratchet, for ordinary service, and a greater distance, say three teeth `of the ratchet, for extra service. For this purpose I have shown a `movable stop 8 (Fig. 1)- normally held by'spring 9 Patented Apr. 22, 1919. i

in contact with stud 10 on casing 1, and adapted, when in the position shown in Fig. 1, to engage the end 5'l of pawl 5, to release the latter from ratchet 3 on the return stroke of said paw] during cach lull movement of arm 6, but when an extra fare is to be registered the stop 8 is moved back and held set, as in dotted lines in Fig. 1, so that pawl 5 wrill continue in engagement with ratchet 3 for an extra tooth, thereby on the forward movement of pawl 5 turning shaft 2 a distance of, say, three teeth. For this purpose shaft 11, to which the flag o-r signal 12 may be attached in any wellknown Inanner, is shown pro-vided with a finger 11 (Fig. 1) which is in such position as not to engage stop 8 when the flag is raised or is in the horizontal or flag-down position, (which 'latter would be the position for recording ordinary fares), but if an extra fare is to be recorded shaft 11 is turned farther to the left in Fig. 1 to cause linger 11a to engage stop 8 and push the same the proper distance away from pawl 5, as in dotted lines in Fig. 1. A spring 12, bearing against the head 11" on shaft 11, serves to retain said shaft in set positions, by reason of the Hat portions 11", 11", 11, on said head engaging said spring.

Upon a rod or shaft 14 extending across casing 1 are loosely mounted any desired number of registering Wheels or disks 15, 15", 15", 15c carrying the desired numerals, as from 1 to 9 and 0 (see Fig. 2), the wheel 15, however, only being provided with, say, three zeros. The wheels 15, 15", etc. are to be rotated step by step in the required order to indicate the fares registered or other accounting to be accomplished. If it be as sumed that the initial charge is to be, say, thirty cents for a definite distance, as for one-half mile of travel, and that each onequarter mile thereafter is to be registered, the Wheel 15 will normally be set to expose its zero a, the Wheel 15 Will normally be set to expose its numeral 3, and the wheels 15", 15c will normally be set to expose their zeros (Fig. 2). At the termination of the rst quarter mile of travel Wheel 15 will be turned to bring its zero I) in line with the numeral 3; at the termination of the next quarter mile Wheel 15 will have been turned to bring its next zero in line with numeral 3, and at the same -time wheel 15a will be turned to bring its numeral 4 in line with the last named zero to register the next coming quarter mile, and so on thereafter for each quarter mile to be registered, but after the first one half mile has been registered Wheel 15 will not be advanced any farther, retaining its last zero in the line of reading.

These results are accomplished as follows:-

On the side of each of said Wheels is secured a. suitable ratchet Wheel 16, 16", 16", 16", re-

spectively, having a desired 'number of teeth, in the example illustrated the teeth being s iaced equal to twenty teeth for each such W eel (Figs. 13 to 16). Upon a shaft or rod 17, is hung a rocker 18 carrying pawls 19, 19, 19, 19, to cnfrage ratchcts 16, 16", 16", 16" respectively. awls 19 and 19 are shown united together, and may operate wheels 15, 15" jointly at a certain time according to the arrangement of the teeth of their respective ratchet wheels (see Figs. 11 and 17). The )avvl 19c has an extension 19'i located back o paWl 19", and extension 19d has a projection 19" to ride on toothed disk or rim 16d formed on or attached to ratchet 16a (Figs. 11 and 14), and extension 19d also has a projection 19 to ride on a toothed disk or rim 16e formed o n or attached to ratchet 16" (see Figs. 11 and 15). Pawl 19" has a projection 19g to ride on disk 16". The arrangement is such that at a certain time said projections will enter the teeth oi one or both of disks 16d or 16" to allow a corresponding pavvl to cause the corresponding wheel to rotate a step, according to the arrangement of the recesses of said disks. Said pawls are shown normally pressed forwardly by springs 20, Figs. 6 and 7. Rocker 18 has an extension 18" shown provided with roller 18" in engagement with a cam 21 on shaft 2 (Figs. 6, 7, 9 and 10) for rocking said rocker to cause the pawls to rotate the registering Wheels when the flag is down, the rocker 18 being moved out of operative relation to the cam when the flag' is up. Back- stop pawls 22, 422, 22", 22c are respectively adapted to engage the ratchets 16, 16", 16", 16, and are shown pivotally supported upon a transverse rod 23. Shaft 11 carries projections 24, 24, 24", 24;" located beneath paWls 22, 22", 22", 22", respectively, and adapted when the Hag is up (Figs. 6, 7 and 8) to raise said pawls from the correspending ratehets. Shaft 11 also carries projections 25", 25", 25", adapted, when the flag is up, to hold the pawls 19a, 19", 19" respectively out of engagement with the corresponding ratchets (Figs. 6, 7 and). Pro jections 25", 25", 25" are at one side of corresponding projections 21", 24" 24, so that the first named projections will not engage pawls 22", 22", 22. When shaft 11 is turned for flag down for registering, 4the projections 24, 24, 24", 24"'allow pawls 22, 22L 22", 22" 4to engage the corresponding ratchets,. and projections 25a, 25", 25c permit pawls 19, 19", 19", 19c to engage the corresponding ratchets. Thus, as shaft 2 is rotated stepby-step, when the flag is down, paWls 19, 19", 19", 19C Will operate to rotate the num bering Wheels step by step, and when shaft 11 is turned back and the flag is raised (Fig. 6) the continued rotation of shaft 2 will not operate the numbering Wheels. To prevent rocker 18 from operating when the flag is up, I provide means for holding said ,JULI i3 rocker out of coaction with can] 21. To is to be thirty cents and the numbering this end shaft 1-1 is provided at the end opposite head 11b (Fig. 3) with a crank pin 26 connected bythe lilik 27 with arock arm 28 loose on shaft 17. Vrl"he end of arm 28 is adapted to engage-the projection 18d of rocker 18 that passes thro h an opening ai in casing 1 (FigpB), a-sprmg 2-9 connected with projection 18d and with casing 1 Serving normally to raise thenrocker. 'In Fig. 3 the parts are shown in the positions assumed With flag up and rocker 18 depressed by arm 28, and when shaft 11 is turned in the direction of the arrow (Fig. 3) arm 28 is raised and spring 29 raises rocker 18, therebv permitting the pawls described to have coaetion with their corresponding ratchet wheels.

In the arrangement illustrated, with the teeth ofthe ratchet wheels spaced corresponding to twenty teeth each, I am enabled to place upon the registerwheels15,'15", 15c each two sets of numbers from one to nine and zero, each of such sets being'upon onehalf the periphery of each such wheel. Hence, the disks or rims'1'6",16- (Figs. 14 and 15) have two recesses or teeth 1.68, 16 spaced a distance of ten teeth', and ratchet wheel 16 has a space 16 (Fig. 16). The teeth ofratchet 116 (Fig. 13), 'while'spaced equal to twenty teethfneed not be completely around the circumference, since pawlf19 only operates said ratchet .a space equal to the last three teeth 16j (Fig. 13), the rcinainderof such teeth being-ina position'to be engaged by pawl 22. The relative arrangement of the ratchet wheels and the recess 168, 16, 16, will be such, with respect to the registering numerals on the corresponding registering wheels 15, 15", 15, that when the zeros of wheels 15, 15, and 15 arein alinement the first tooth 16j wil-l beengaged by pawl 1-9 to rotate wheel 15 one step, and numeral 3 of registering wheel 15a (providing the initial charge is to be thirty cents) will be in alinement with said zeros, and at such time a recess 16g of ratchet 16 of numlieringr wheel 15" will be in such position that when the numeral 9 of said wheel is exposed in the reading line with the zeros. the extension 19e of pawl 19c and the extension 19g of pawl 19 will be opposite such recess 165 .until the proper time. The recess 16 of disk 16e of ratchet wheel 16b of numbering Wheel 15b alines with projection 19'fv when a numreal 9 of wheel 15b is in the reading line andat such time the projections 19, 19, 19g may fall into the respective recesses 16 and' 16g and thereupon wheels 15a,:15,15 are turned one step together. Thezrecess 16* of ratchet 16C of numberingwheel'1-5c is in lineavith a numeral 9 infront. so that when suohrecess 16* alines with pawl 19c the Vwheel 115c will not be rotated any farther. AWith the arrangements described,l assuming the initial. ycharge -wheels are in the positions shown in Fig. 2, whentheliag is turned down rocker 1S is raised into coaction with cam 21, and as shaft 2 is rotated, either by the road Wheel or by the clock mechanism (hereinafter de scribed) pawl 19 on the rst rise of rocker 18 will rotate numbering wheel 15 one step by coaction with the first tooth 16I and on the next rotation of shaft 2 pawl 19 will rotate numbering wheel 15 another step, by coaction with the second tooth 16 and said pawl `falls into the space below the third or last tooth 16 permitting pawls 19, 19al to advance to enable pawl 19al to engage ratchet 16a; upon the next rotation of shaft 2 pawl 19will not operate wheel 15 any more, (until reset to flag up position) and pawl 19a on the next rise of rocker 18 will rotate wheel 15 one step (being an advance charge for the next quarter mile) and so on, wheel 15 being rotated until ninety cents is registered, at which-time a recess 16s will be in alinement with projections 19 and 19g. If the charge now runs to one dollar on the next rotation of shaft 2 the projection 19g will enter recess Y116g thus permitting pawl 19d to engage ratchet 16", but projection 19e will be held back by projection 19t' bearin upon the surface of disk 16,then upon t e next rise of rocker 18 pawl 19a and pawl 19 will rotate the respectiveratchet 16, 16b turning the `eo:responding numbering wheels 15, 15",

thus registering one dollar. Registration according tothe foregoingr is continued until $9.90 are registered and thereupon a recess .16g will be inthe position last before mentioned and a recess 16 will have been brought intoffalinement with projection 19f, and on the next upward movement of rocker 18 the projections 19 and 19g will both enter such recess 16B and the projection 19r will enter'recesslhpermitting pawls 19a, 19" and 19 to engage their respective ratchets and rotate their respective wheels, thereupon turning wheels 15, 15, 15c jointly one step to register $10. The step by step registration of the wheels will thus occur continuously until space 16i of ratchet 16c is brought into alinement with pawl 19, whereupon wheel 15 will not rotate any more, where- ,upon $99.90 willhavebeen registered. This being the limit o'registration shown in the drawings with four registering wheels, all the Wheels may be restored to intial charge. Of course, it willv be understood that as many numberin wheels as desired and with their correspon ing pawls and parts may be installed. The arrangement set forth is advan tageous in that it enables in a simple manner ythe restoration of the numbering wheels to zero ernormal-position at any tlrne the flag is turned up. I have illustrated means for such purpose and i-n order that each of the numbering: wheelsthatzmay have been opertoration of such wheels,

w eel, whereby when said ratchet wheel ris rotated in the direction of the arrow in Fig. 7, projection 32 by engaging lever 31, will 1 A ing wheel 15 and with ated on a trip will return to zero or normal,

the trip when the flag is restored or turned up, irrespective of the extent to which such wheels lnay have been rotated on a trip, and in order also not to unduly wind the springs which cause the res at the termination of lowing arrangements, and since the Wheels 15 and 15 are restored vices, and the wheels 15, 15" are restored by corresponding devices, adescri tion of one set of each such devices ring `first to means for restoring the registering wheels 15'* and`15" to normal or zero, the arrangements are as follows: The ratchet wheels 16, 16", are secured to the corresponding numbering wheels 15, 15", which ratchet and numbering wheels are loose on shaft 14, but are operatively connected with said shaft by spring 30 for restoring the numberin wheels to normal (see 1F igs. 7 12 and 15 Spring 30 is connected at one endvvith shaft 14 and at the other end with a disk 16k loose on shaft 14. Disk 16k carries` a lever 31 pivotallyT supported thereon and the end 31 of said lever is Aadapted to engage a rojection 32 on thecorresponding ratchet cause disk 16k to be rotated andthe spring wound. The arm 31" caused to make nearly a complete revolution,

carrying the corresponding numbering wheel around with it, and disk 16k has been correspondingly rotated by, engagement of projection 32 with arm 31, and projection 32 is approaching dog 34, or engaging the same, arm 31" will engage stop 33 and at the completion of the stroke of pawl 19, lever 31 will have been titlted to release its from projection 32, whereupon spring 30 Will cause disk 16k to return to normal, and projection 32 will pass under dog 34. This enables spring 30 to be wound at least a complete revolution, but prevents overwinding of the spring. Should a numbering however, be -stopped at any other point in its rotation, as by reason of the trip terminating and registering on the numbering wheel any corresponding numeral, is turned to show flag up, andthe pawls are remain in engagementA with its projection 32 'l I provide the fole by correspondingldewill su ce. Refer-3 of lever 31 is adapted to engage a stud 33 upon the casing'vvhenl the numbering wheel is approaching the terl 34, as shown has been l Wheel,

then when shaft 11' sli'aftll for flag up.

The numbering wheel 15 need not be provided Vwith @disk4 16-L ,and vlever 31, but its spring 30*i (Fig. 12) may be connected directly to the numbering Vwheel 15, and to the shaft, as by being connected with spring barrel 30b that is secured to shaft 14, and the projection 32a of ratchet 16 (Figs. 2 and 13) will engage stop 34 to retain wheel 15 against the tension of 4its spring to normally expose zero a.- This arrangement is adopted because registering wheel 15 is not caused to make a. complete rotation.

The numbering w-heel 1 registering the highest numbe'r, such as wheel 15, also need not be provided with dislrlt'k and lever 31, sincesuch wheel is not intended to make morethan-one rotation, ,and in the example illustrated does-` not make more than onehalf rotation, For this purpose spring 30 (Figs. 12fand 16) `is connected with numbershaft 14 as by being connected with spring barrel 3()d secured to shaft. 14. v Ratchet 16 is shown provided with projection 32b to engage stop 34 (Figs. 2 and 4), looatedin such position as to normally retain the zero of Wheel 16 in the readingline (Fig. 2). When wheels 15 and 15c have been rotated any' distance for registering, their return rotationat such time is prevented by the correspondin dog 22 and 22, but when shaft 11 is turne for Hag up and said dogs release their ratchets their corresponding springs will restore wheels 15 and'15c to normal, the projections 32, 32h then engaging the corresponding 'stops 34a and 34". By the arrangement set forth it will be understood that all ofthe registering wheels, while advanced step by step for registering, are maintained under spring tension to restore them to their normal positions, and that after registering hasoccurred wi hv Hag down, and the trip or engagement is ended,'a`nd the flag is to be turned up, such corresponding rotation of shaft 11 will, by reason of its project'ons 24` 24, etc., raising the stop dogs' 22, 22, etc., from the ratchets, and the projections 25, 25", etc., moving pawls 19, etci, back from the ratchets (Fig.

permit the vs rings of any of the registering wheels that lave been advanced to cause such registering wheels to return to normal, and be stopped at normal 'by engagement of their correspon 'ng projections 32 with the stop 34, etc.,- so that each time that the flag is turneddown, the registeringfvvheels wil be finger 36b registering in the manner in position to start advance or 1n1t1al charge described with the already registered.

In order that cam 21 may depress rocker through the action of the road Wheel When registering for mileage, as Well `as to enable registering according to time elapsed when the taxicab is not traveling but iS under hire, I provide means to operate rocker 18 and pawls 19a, etc., under either of such conditions, and to stop such actions when the flag is up, and also to throw into action means for recording of mileage made by the taxicab when the flag is up, as on a return .trip from an engagement or when fares are not being registered. To this end I secure a ratchet 36 (Figs. 7 and 8) upo-n shaft 2, and also mount loosely on said shaft a ratchet wheel 37 to Which is secured a gea-r 38 (Figs. 5, 6 and 8), which gear is adapted to be driven by a gear 39 of a clock train 40 (Fig. 3). Cam 21 carries a pawl 36a to engage ratchet 36, and also carries a paivl 3'?a to engage ratchet 37 (Figs. 5, 6, 7, 8 and 10), which pawls are shown carried by an extension 21*l of said caln. Pawl 36*L 4has a to be engaged by a cam 41 slidable along shaft 2 (Figs. 5 and 8) and connected With said cam is a cam 41n to engage finger 37b connected with pawl 37 (Figs. 5, 6 and 8). In the arrangement shown in Fig. 8, shaft 2 has an enlarged portion 2a, having a bore receiving` a rod 42 provided With a pin 43 passing through slots in shaft 2 and connected with cams 41, 41 which are mounted slidably on enlarged portion 2a of shaft 2 (Figs. 8 and 10), whereby as rod 42 is moved t0 the right or left said cams will be correspondingly moved. Rod 42 also carries a finger 44 (Figs. 5, 6 and 8) which is adapted, in the position shown in Fig. 5, when vthe flag is up, to engage a tripper 45 (Fig. 6) of a counter orreglster 460i' any well .known construction, lwhereb each time shaft 2 is rotated by the Hag is up) the registry wheels of Vregister 46 will be correspondingly operated to register mileage. To slide ro 42end Wise as required, I have shown the outer end -of said rod provided with a grooved collar 47 receiving the yoke 48 on a roc -arm 49 pivoted upon casing 1, as at 50. The upper end of arm 49 is shown movably connected by a .pin-and-slot connection with a bellcrank lever 51, the upper-arm of which engages the forked or slotted end 52a of rock arm 52 pivotally supported 4at 53 on. the casing (Figs. 3 and 5). The relative arrangement of the parts is such that when the flag is :up (Fig. 5) rod 42 Will have been pushed inwardly, Vbecause crank y.pin 26 will then be `depressed and will have depressed arm 28, roc-ker 18, and the right hand end of arm 52 (Fig. 3), thereby tilting lever 51 ;up.wardly, causingarm 49i to .push rod 42 inthe road wheel (when. Speed fOr rotating cam 21 wardly and thereby cams 4-1 and 41 are pushed into engagement with the corresponding lingers 36" and 37b and hold their corresponding pawls 36, 37EL out of engagement with ratchets 36, 37, (preventing operation of cam 21), and finger 44 will have been brought into coactive relation with tripper 45, whereby rocker 18, pawls 19EL etc., and wheels 15, 15a, etc. will not be operated either by the road wheel or the clock train, but the register 46 Will be operated to record mileage because of the rotation of shaft 2 and `plunger 44, which will be such mileage as is not charged for. When sha'ft 11 is turned with flag down, crank pin 26 will rise, lifting arm 28 from extension 18d, permitting the rise of rocker 18 and setting the pawls 19a, 19h, 19c and 22, 22, 22", 22c in positions for operating the numbering Wheels 15, 15a, 15h, 15", and Withdrawin finger 44. from alinement with tripper 45, Eecause the forked end of arm 52 then descending tilts lever 51 to cause arm 49 to pull rod 42 outwardly, thereby also shifting cams 41 and 41a from alinement with fingers 36, 37b, thus enabling the pawls 36, 37 to coact with the ratchets 36, 37. The rotation of shaft 2 by the road Wheel will now, through the medium of ratchet 36 acting ufpon pawl 36, cause rotation of cam 21 to operate rocker 18 to actua-te the registering Wheels 15, etc., Without affecting register 46. Should the taxicab come to rest with the flag down, the clock-train operating gear 38, will, by such gear, cause ratchet 37 to rotate, which, by engagement with paw] 37a, will rotate cam 21 to operate rocker 18. As mileage is usually counted at greater speed than time charges, it will be understood that there will be no interference by the action of the road Wheel in rotating shaft 2, to operate cam 21, and the clock train operating said cam through the mechanism described. In other words, the devices having .the greatest at any given time, Will operate said cam.

Since cam 21 `is rotated continuously by Vshaft 2 of the clock mechanism Wheniregisist/op at a position not its normal position,

that is to say, with roller 18b the Wide part of the caen the` depressed part 21b (Fig. v9), the next user of the cab would be charged for `mileage not used by him, since as soon as roller 18b dropped from the high part 21 of the cam into the depressed part 21" of the cam (Fi 9) thepawls 19, etc., would register. dei) overcome this objection, and to cause cam 21 always to be restored to its normal position with roller 18" ynormally resting in the depressed pant 21b ofthe cam when the flag is turned down to start a trip under hire, I provide the following arrangement, which is bearing upon and not resting in in many respects similar to the arrangement described with respect to the spring and the tripping device illustrated in Figs. 14 and 15. Aft one side of cam 21 is a disk A loose on shaft 2 and a spring B is secured at one end to said disk and at the other end to spring barrel C that is secured to casing 1. Disk A carries a lever D normally pressed by a spring E into engagement with a projection 21d (Figs. 8 and 9) at one side of the high part 21c of the cam, whereby when said cam is rotated in the direction of the arrow in F io. 9 disk A will be correspondingly rotated and spring B will be wound. A stoppin F on disk A engages lever D when the parts are in the positions shown in Fig. 9. The arm D of lever D is adapted to engage a stud G on the casing (Figs. 6 and 9) to trip lever D from projection 2ld of the cam when the cam approaches its normal po sition to prevent overwinding of the spring B, although when the fares are being registered the cani will continue to rotate indefinitely, disk A b-eing tripped as described each time the cam makes one rotation. lhen, however, the flag is turned up, and the pressure of roller 18b against cam 21 is relieved by the depression of rocker 18, and the pawls 36', 37" are then released from the ratchets 36, 37, (by the sliding of cams 41, 41al to the left in Fig. 8 as before. described), the tension of spring B through disk A and arm D against projection 21d of the cam operating in the reverse direction to the arrow in Fig. 9, will rotate cam 21 in a reverse direction to its normal direction of operation, and the cani will be stopped by the check dog H engaging projection 21d, at which time roller 18b of rocker 18 will be in position to fall into the depression 21 of cam 21 when the flag is next turned down. whereupon cam 21 will then begin to art upon rocker 18, at which time the registering Wheels will have been returned to zero so that each passenger will b-e charged only from the normal ositions of the cam 21 and not from any a vanced osition left from some preceding trip. e check dog H, Fig. 7, is shownpivoted upon the casing at I and held under spring tension by spring J, and thereby projection 21d, when rotating in the direction of the arrow in Fig. 9, may slide freely past dog H.

In order to register ermanently mileage, such as quarter miles when fares are being charged) I provi-de a suitable register 60 of any well known character. For this purpose I utilize finger 44 to engage a rock arm 61 (Fig. 6) pivdted at 62 and pivotally conneoted at 63 with arm 64, of register 60, the spring 65 4acting normally to draw the parts, as in Fig. 6, whereby when the flag is turned down and shaft 11 is thus turned to permit pawls 19a, etc., 22, 22, etc., to coact with the ratchets of the registering wheels charge.

15, etc., linger 44 will through the rocking arm 49, have been shifted by rod 42 from alinement with tripper 45 into alinement Wiith arm 61, and the latter will cause arm 64 to rock to operate register 60, each time shaft 2 is rotated.

In order to register each time that the Hag' is turned down, to thereby indicate the number of initial charges, suieh. as each. thirty cents for the first half mile charged, shaft 11 is provided with a projection or rain 68 (Figs. 2, 4 and 5, 7 and 8) adapted to operate arm 69' shown pivotally supported at 70, and )ivotally connected with rock arm 71 (Fig. 4i of a register 72, the arrangementshown being such that when the iag is up (F ig, 7) cam 68 will be free from arm 69 and the lat-ter will be depressed by spring 69a to likewise depress arm 71, and when shaft 11 is turned for flag down, cani 68 will be raised and will engage |and raise arm (35|, thereby raising arm 71 and causing the `proper wheel of register 72 to register. Such turning of shaft 11 therebyT registers each initial charge for flag down, or each time the flag is depressed, and on the return rotation of shaft 11, to the position of flag up, arm 69 will be depressed ready for nnother operation of register 72.

In order to register each charge for fractions of a mile, such as ten cents for each quarter mile after the initial charge (such as thirty cents for the first quarter mile) with flag down, I provide a register 73 which may be supported beneath register 72 and operated each time pawl 19a is operated. For this purpose the arm 74 of register 73 (Figs. 7 and 11) is pivotally connected with an arm 75, shown hung upon a rod 7G carried by casing l, a spring 77 connected with arm 75 tending normally to raise the parts. The bent end 75a of arm 7 5 lies over a projection 19c (Figs. 6 and 11) of pawl 19 when shaft 11 is set for fiag up, and pawl 19a is in mesh with ratchet 16, whereby each time rocker 18 then rises to register fares, projections 19 will engage projection 75L and operate register 7 3 to indicate each such quarter mile or ten cent When shaft 11 is turned back for flag up and awls 19a are withdrawn from their respective ratchets, projection 19x will be drawn from beneath projection 75 and register 73 will not o crate. A. stop 78 (Fig. 6) engages arm 5 to resist the upward pull thereon of spring 77.

In order to register extra charges made While the taxicab is in service or under employ, and alsoto register the totals of such extra charges for permanent record, I provide the following means: Upon shaft 17 are loosel mounted numbering or registering Whee s 80, 81, which may be arranged similarly to registering wheels 15" and 15c respectively, having corresponding numerals amm.

as before described: f'llheWWheelSO has` a ratchet 82' and! wheeh 81- hase ratchet4 83' operated respectively b pafvvls` 84, 86, pivotall carried u on roc er8i, supported'by brac et 8f? on' ame` 1.'i 'Upon' the side of ratchet Wheel 80l is a notched disk 88, the two notches 88a beingequall spaced (as ony disk 16) and a paWl T859 connected With pawl 85 (Fig. 19) is adaptedf toI ride upon disk 88 and to 4,enters its notches 88a. When paWl 85Mides on disk 88 pawl 85 will be. held out of engagement With ratchet` 83," but pavvl`84'ifbeiirg" movableindependently of paWls 85 and 853' is always adapted to coact with ratchet 82. Springs 89, 89a, coacting With paWls 84, 85 and with rocker 86, (Fig. 19) hold said pawls in operative relation to ratchets 82, 83 and disk 88. Pavvls 84 and 85 are provided with projections 90 (Fig. 6) adapted, When rocker 86 is depressed, to engage the bottom of said rocker and'maintain the pawls out of contact with ratchets 82, 83. The arrangement is such that When rocker 86 rises, turning on the pivot 91, the paWls 84, 85 may engage their respective ratchets, and When rocker 86 descends to the normal position (Fig. 6) projections 90 hold pawls 84, 85 out of engagement with their ratchets ermitting reverse rotation of the latter. ocker 86 is to be raised and lowered, to actuate Wheels 80 and 81, and for this purpose I have shown a projection or cani 92 on shaft 93 carried by casing 1 and bracket 87 (Fig. 6) and having a suitable head 94 (Figs. 1, 2 and 5) which may be rotated whenever it is desired to register an extra fare. Registering Wheel 80 and its parts may be made in accordance with the construction shown in Fig. 15, having a stop or projection 95, and lever 96 to coact therewith (Fig. 2), the stud 97 serving to trip said lever to release the tension of the sprin of Wheel 80 to allow the corresponding dis carrying lever 96 to return as described with respect to Fig. 15. The stop dog 98 (Figs. 2, 4 and 18) coacts with stop 95 to cause the zero of registering wheel 80 to come to the reading line when the flag is raised. A pawl 99 (Figs. 1, 2, 5 and 18) for each ratchet 82, 83, is mounted upon shaft 76 ('Fig. 18) and adapted to engage corresponding ratchets 82, 83, bein normally pressed down by spring 100. haft 11 is provided with projections 101 (Figs. 4, 5 and 18) to engage the extensions 99a of pawls 99, said projections being in such position that when shaft 11 is turned to position of flag up, projections 101, acting upon the projections 99a, Will raise pawls 99 from the ratchets 82, 88, and when shaft 11 is turned flag down, projections 101 will permit pawls 99 to engage their corresponding ratchets to prevent return rotation of numbering Wheels 80, 81, as they are being operated forwardily. The numbering wheel 81 and its ratchet'83 are provided with a spring arrangement similar to that shown in Flg.

16, the pin 88."L (Fig. 18)- being adapted to` engage stop 102 to permlt Wheel 81 to retain its zero in the reading-line with the flag up. In order to register the totals of the numberingl Wheels 80, 81, I provide a suitable registering device 103 of any Wellnevvn` construction (Figs. 1, 2 and 6) the operating` army 104 of which is connected by link 105 With projection 92, whereby when the latter isf rocked, arm 104 will be rocked: tocause operation of the wheels of register 103. Thus, each time projection 92 is raised to cause rocker 86 to operate its paWls to actuate registering wheels 80 or 81, arm 104 will be rocked to register as a permanent total of such operations of Wheels 80, 81, regardless of the fact that such Wheels 80, 81 are restored to normal or zero position each time the flag is raised.

Changes may be made in the construction and arrangements of parts set forth, Within the scope of the appended claims, Without departing from the spirit of my invention.
