FARE-REGISTER.

SPECIFICATION forming part of Letters Patent No. 531,020, dated December 18, 1894.

Application filed October 24, 1893. Serial No. 439,061. No model.)

To all whom it may 0072 067713 Be it known that we, EPHRON OATLIN, a citizen of the United States, and GUsTAvUs REIN, a subject of the German Emperor, both residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Fare-Registers, of which the follo wing is a specification.

This invention relates to that class of street IO car registers in which is employed a step by step revoluble index moving over a fixed register-dial forming the trip register, together with a permanent register or set of adding wheels that is or are moved in unison with [5 the index of the trip register to preserve the sum of the operations of the register while the index may be returned to zero.

The present invention embraces certain improvements upon such registers, which more particularly reside in the means for returning the trip register to zero; in the means for locking and releasing the permanentregister during and upon the completion of the return of the trip register to zero; in the means for changing the position of the direction-indicator; and also in certain details of construction and combination of parts fully hereinafter set forth.

In the accompanying drawings which illus- 0 trateapractical embodiment of theinvention:

Figure 1 is a face view of a fare register embodying the improvements, a part of the register-dial being broken away to disclose a portion of the underlying parts. Fig. 2 is an 5 elevation of the mechanism of the register underlying the register-dial which has been removed, the wheels of the permanent register being omitted. Fig. 3 is a vertical cross section on the line 33, of Fig. 2, showing only a portion of the base or back-plate, with the parts in normal operative position. Fig. 4. is a horizontal section on the line 4-4, of Fig. 3, showing particularly the locking device for the permanent register. Fig. 5 is a 5 section similar to Fig. 3, with the parts in a changed position at the time the trip register gear has been disconnected from the permanent register, and the latter register locked against movement. Fig. 6 is an end elevation of the devices for actuating the register, showing the pawl, pawl-carrier, ratchet, and

bevel pinion. Figs. 7, S, and 9 are enlarged detail elevations partly in section of the parts and portion of the parts shown in Fig. 6,with the addition of a portion of the bell hammer illustrating the action of the pawl upon the bell hammer. Fig. 10 is a plan view of some of the parts shown in Fig. 7 with the bell hammer and portion of the bell showing how the head of the bell hammer is held a short distance from the bell after each striking movement. Fig. 11 is an enlarged sectional detail of the toothed wheel and anchor-lever for operating the direction-indicator. Figs.

12 and 13 are views of the means for locking and releasing the anchor-lever. Figs. 14 and 15 are sectional elevations of a hold-back pawl in inactive and active positions.

Referring to said drawings, it will be understood that the mechanism of the fare reg- 7o ister, considered as a whole, is supported by a base plate A, surrounded as usual by an inclosing case B. The mechanism embraces a trip-register represented by the rotatable step by step movable index hand'ioverlying the register dial D, and a permanent register E represented by a number of adding wheels (shown in Fig. 1), adapted to preserve the sum of the operations of the trip register.

The dial D is permanently mounted on suitable posts projecting from the base plate A and is provided with a central perforation for the hub 80 of a bevel gear 20, and with openings d, d, one for exposing the numerals on the wheels of the permanent register E, and the other for one or the other of the indications of a direction indicator H. The bevel gear 20 is mounted to rotate loosely on a journal formed by a central post or stud 2i projecting from the base plate A, the inner 93 end of the hub 80 resting normally on a shoulder formed integral with the post 21. As shown in Figs. 3 and 5 the post 21 is a separate piece firmly and rigidly seated in a boss on the base plate A. To the outer side 5 of the hub 80 of this gear 20 is fixedly secured the index i, it being in this instanceinterposed between said hub and the shank c of a projecting grasping piece 0, screws 0 being tapped into the hub 80 to secure said [00 grasping-piece, index, and hub together. The shank or hub c of the grasping piece 0, the

bevel gear 20, and the post 21 having a central perforation in which is supported a longitudinally movable rod or stem 43 having at its outer end projecting from the center of the grasping piece 0 a thumb piece or knob e.

Between the inner end of the thumb-piece e and an inner shoulder in the hub c is interposed a helical springfsurrounding the rod or stem 43, by which spring the rod 43 is held outward and the grasping-piece c and connected bevel gear inward and thus permits, as will presently appear, an inward movement of the rod 43, and an outward movement of the grasping-piece 0 against the pressure of said spring f.

The bevel gear 20 when in its normal position as in Fig. 3, meshes with a bevel pinion 22 that is fixed to a horizontal shaft 25 of the adding wheels of the permanent register E so that the trip register and the permanent register shall move in unison. The shaft 25 is mounted in bearings in a frame that is rigidly fixed to the base plate A at one side of the axis of the bevel gear 20. The shaft 25 has also secured to it a ratchet 24: with which engages a pawl of the actuating de vice. The pawl 23 is connected to a pawlcarrier 26 that is hung loosely on the shaft 25 and has an operating finger 27 projecting through a slot in the base-plate A which is intended to be engaged by an actuating slide (not shown) that is in turn connected to one or more operating cords extending through the car to be pulled by the conductor to rock the pawl carrier 26 and its pawl 23 in one direction against the force of a spring connected to the slide, which spring as soon as the operating cord is freed by the conductor returns the slide to its normal position and also rocks the pawl-carrierand pawl back to their starting positions, completing one registering movement of the connected parts. This slide and the spring is not herein shown, as its construction and operation are now well known, an example and description thereof being found in Letters Patent No. 490,342, granted January 24:, 1893, to Leo Ehrlich.

The pawl 23 is formed with a projecting hub to at its pivotal connection with the pawlearrier 26, and at its free end with a nose to for coaction with the bell hammer in a manner to be explained, and said pawl is held to duty in engagement with the ratchet 24: by a compression spring 3 that is held in a socket 2 formed in said pawl-carrier.

Each time the pawl carrier is oscillated or rocked once forward and back, a single step j (see Fig. 1), of the permanent register one j another step and so on.

step and through the bevel pinion 22 and gear 20, the index 2', one step, thereby registering one fare. Arepetition of the oscillation of the pawl-carrier moves the index iand units wheel The units wheel j is fixed to the shaft 25 as in said patent. Any backward movement of the ratchet 24: is prevented by a hold-back pawl 10 pivoted 011 a stud projecting from the frame 35 and projecting through an opening 10 in the pawl carrier 26, as seen in Fig. 7, said pawl 10 being held to duty by a spring 10 coiled about its pivot stud.

The bell hammer 55 is mounted on a pivot 56 projecting from the base-plate A, see Figs. 2 and 10, and is arranged to strike the hell I upon the forward movement of the pawl-carrier 26, indicated by the arrow in Fig. 7, through the instruinentality of the pawl 23. To this end the bell hammer 55 is formed beyond its pivot with a heel 5 (as seen in Fig. having a flange that provides a notch or step 6, (see Figs. 7, 8, U, and 10) which flange is arranged to be borne upon at different times by the nose at of the pawl 23 and by the hub a, of said pawl. lVhen the pawl carrier 26 is rocked forward as indicated by the arrow in Fig. 7, the end of the pawl 23 in moving past a tooth of the ratchet 2% is rocked or forced outward as indicated in Fig. 8, so that its nose a strikes against the flanged heel 5 of the bell hammer 55 thereby rocking said hammer and carrying its head away from the bell I. As the pawl-carrier 26 and pawl 23 continue to move in the direction of the arrow, Fig. 7, the pawl 23 under the force of its spring 3 suddenly vibrates'into engagement with the tooth of the ratchetso that its nose at leaves the heel 5 of the bell hammer 55 and allows said hammer to likewise suddenly strike the bell. On the return oscillation of the pawl-carrier 26 and pawl 23 in moving the ratchet 2ione step, the hub a of said pawl bears against the flanged heel 5 of the bell hammer, and said flange being slightly cam shaped or not concentric with the are of movement of the pivot of the pawl 23, said bell hammer 55 is rocked slightly on its pivot to carry its head away from contact with the bell which it has just struck, as is shown in Figs. 2, 7, and 10. The movement of the head of the bell-hammer away from the bell takes place immediately after the bell has been sounded and hence the continued bearing of the hammer upon the bell does not tend to lessen its vibrations. As the pawl-carrier 26 nearly reaches the limit of its forward oscillation, the pawl 23 or its nose a is arranged to engage or enter the step or notch 6 in the heel 5 of the bell hammer 55 and thus prevents a premature backward movement of the pawl-carrier at such time, as is seen in Fig. 0. In this position of the parts the pawl 23 has not quite engaged with the tooth of the ratchet 2t, and is thus obliged to make a slightfurther movement to drop into the depression of such tooth. As soon as this occurs the nose a of the pawl. 23 has been freed from the notch 6 of the bell hammer and hence said pawl is enabled to move back to its original position moving the ratchet 2% and its connected parts one step forward. By this construction of the bell hammer and its coaction with the operating pawl 23, the very important function of preventing a return movement of the pawl before reaching the limit of its stroke is prevented. l-Ieretofore this guard against the premature return of the pawl has been effected by a toothed edge and detent on the inner side of the false back plate with which these registers are usually provided as in said former Letters Patent No. 490,342, but the perfection of its working depended upon the accuracy with which two independent castings were interlocked, and much trouble was found in practice to obtain this accuracy in view of the different degrees of shrinkage of the metal. In the present construction, as the pawl and bell hammer are fitted to and carried by the same back plate the former difficulty is entirely overcome.

In the course of the use of the register as thus far described the trip-register wheel 20 is rotated step by step with the index 2 carrying said index away from the zero mark on the dial and also carrying an abutment n rigid with said wheel 20 away from the free end of the zero stop it which stop is mounted yielding in one direction only, so as to permit said abutment n in the forward movement of said wheel 20 when having registered one hundred fares or made a complete rotation to pass said stop without interference, but said zero stop is fixed in the other direction so that when the wheel 20 is rotated back to the zero position its abutment n will strike the end of the zerostop 7t and the wheel be held against further movement in that direction. To effect this backward rotation of the wheel 20 and index i, the teeth of the wheel 20 are first removed from mesh with the pinion 22 and for this purpose the operator grasps the hand wheel or grasping piece 0 and pulls it outwardly against the tension of the springf. In order, however, to first lock the permanent register Eagainst niovementw'nile this disconnection of the wheel 20 and pinion 22 occurs and to prevent this disconnection. until the lock is moved into locking position, the rod 43 is pressed inwardly also against the tension of said spring 7, by a pressure of the finger upon its thumb-piece c. This inward movement of the rod 43 forces a pin 0 (which it carries projecting through a slot 0' in the central post 21) against the inclined upper end of an L- shaped slide 0 forming the look so that said slide is moved outwardly in its guideway on the base plate against a compression spring 0 so that its outer end is moved in front of a project-ion or engaged witha recess 0 in the pawl-carrier26,seeFigA andthereby securely locking said carrier and its pawl against movement. This locking slide 0 carries afinger or guard 0 that normally overlies a flange or shoulder 0 on the hub 80 of the wheel 20 and hence resists any tendency to move the wheel 20 outward to disconnectit from the pinion 22; but when the locking slide 0 is moved into locking position this finger 0 is simultaneouslyremoved fromoverthe flangeoflseeFigfi,

and henoereleasesthewheel 20. Inthis moved position of the guard 0 its end bears against the circumference of the flange 0 and thus prevents the return of the locking slide 0 until said flange is removed by the return of the wheel 20 to normal position. As soon as this wheel 20 is disconnected from the pinion 22 said wheel is then free to be rotated backwardly until stopped by a secondary zero stop a mounted on the lever n meeting a projection a on the upper side of the wheel 20; this secondary stop being provided mainly for another purpose as will be presently explained.

The direction indicator II is moved to change its indication each time the trip register wheel 20 is disconnected from the pinion 22, it not being dependent for its movement upon the backward rotation of the trip register to zero position because in some instances no fares may have been collected and hence no movement of the register has taken place during a trip of the car. The secondary stop a is carried at the end of the short arm of a lever N that is pivoted on a stud p projecting from the base plate, a coiled spring p tending to rock the lever in the direction of the arrow in Figs. 2 and 12. The other or longer arm of the lever N is shaped in the form of an anchor lever having palletsp {see Figs. 2 and 11) in position alternately to engage the teeth of star wheel 19 that is secured to a shaftp carrying at its outer end a disk on which are delineated the direction indications. The tendency of the coiled spring 1) is such that as soon as the wheel 20 is disconnected from the pinion and its projection a raised into alignment with the stop n said wheel 20, assuming said wheel has not been moved during a trip of the vehicle is rotated forward slightly by the force exerted by said secondary stop n upon the projection of and thus permits said coiled spring to rock the lever N in the direction of the arrow Fig. 2, to throw the opposite or anchor portion of the lever into the position shown by dotted lines, Fig. 11. This movement of the lever N has forced one of its pallets 19 into contact with the star wheel 19 and moved it a partial step in the act of imparting a full step movement to the direction indicator disk H to change the indication. The slight forward movement of the wheel 20 under the action of the spring 13' only occurs when the projection n is against the stop vi the register not having been operated during a trip; but, should the register have been operated and the projcc tion a consequently removed, a more or less distance from the stop if, said slight forward movement does not occur. The remaining portion of the step movement of the direction indicator is effected by the return vibration of the lever N brought about by the forcing backward pressure of the projection. 01 against the stop a to rock said lever in bringing the wheel 20 exactly to the zero position.

While the wheel 20 is in operative position IOC in mesh with the pinion 22 the lever N is held against premature movement by the extreme end of the hub of the wheel. 20 being interposed in its path of vibration as in Figs. 3 and 12, preventing any movement of said lever, but when the wheel 20 is moved outwardly out of mesh with the pinion 22 in the act of returning it to zero position the hub is moved from its positionrestraining the lever N, whereupon under the force of its springp' it rocks below the end of the hub against the central post 21 as in Figs. 5 and 13. When the lever N is rocked back to its original position on the return of the wheel 20 to zero, the hub 80 of the wheel 20 is again interposed to hold the lever against movement.

Any forward movement of the wheel 20 when in its disconnected position is prevented bya pawl q, that is pivoted to the outer short arm end of the lever N, see Figs. 2, l4, and 15, and borne upon by a compression spring g. hen the wheel 20 is down in its normal position the pawl q is forced and held downward against the slight tension of its spring q as in Fig. 14, and the teeth of the wheel 20 ride overits bodyportion its free end thus not ottering any obstruction to the forward rotation of the wheel; but when the wheel is raised as in Fig. 15, into disconnected position as before explained, the end of the pawl q moves to its active position in engagement with the teeth of said wheel 20 to prevent forward rotations.
