Application filed September 8, 1906- gelifll NOI T0 ctZl whom it may concern:

Be it known that 1, CHARLES E. GIERDING, a citizen of the United States of America, and a resident of Newark, in the State of New Jersey, have invented a new and useful Improvement in F are-Registers, of which the following is a specification.

This invention relates primarily to the zero-stop mechanism or devices of fare registers or recorders or combined registers and recorders, herein referred to in common as fare-registers, but the improvement may be embodied in part in registers or recorders or combined registers and recorders other than fare-registers. These latter are herein referred to in common with fare-registers as registers.

The improvement is confined to those fare registers or other registers in which decimal numeral-wheels are employed and in which provision is made for turning such wheels backward to zero from time to time, as at the end of each trip or each period covered by a fare in the case of fare-registers and the leading object of the invention is to adapt the nearly common intermittent spur-gear carrying or transmitting mechanism of such numeral-wheels to form effective zero-stops for the units-wheel and such other numeralwheels as may have a wheel of higher value to the left of them.

Other objects of the invention will appear from the general description which follows.

The invention consists in certain novel combinations of parts hereinafter described and claimed.

Two sheets of drawings specification as part thereof.

Figures 1 and 2 are respectively aface view and an edge view of a fare-register embodying the invention. Fig. 3 is a face view, on a larger scale, of the back part of the registercasing shown at the right in Fig. 2 and of the parts within the same, omitting those parts which do not form elements of any of the combinations hereinafter claimed and are not considered necessary for a full understanding of the present invention. Fig. 4 represents a section through the mechanism of the fareregister on the line A B, Fig. 3, looking in the direction of the arrow 00, Fig. 3, with some of the parts in the plane of section in elevation. Fig. 5 represents a section on the same line looking in the direction of the arrow at, Fig. 3; and Fig. 6 represents the same section as accompany this Fig. 4 with the numeral-wheel in the foreground in a different angular position, illustrating the registering operation.

Like reference characters refer to like parts i in all the figures.

The external characteristics of the fareregister shown in the drawings include a circular drum or casing (shown complete in Figs. 1 and 2) and composed of separable back and front parts 1 and 2, made, respectively, of cast metal and sheet metal, together with a transparent dial-cover 3, of glass, behind which the indications of tripregiste'r numeral-wheels a, totalizer numeral wheels I), and a direction-indicator c are exposed to view through the respective apertures a, b, and c of an apertured dial-plate 4. as in Fig. 1.

Other external characteristics are means for actuating said trip-register and totalizer wheels to register each fare on both, such actuating means being represented by the customary rearWardly-protruding stud 5, Fig. 2, and means for periodically resetting the trip-register wheels to zero and operating said direction-indicator 0, such resetting and operating means being represented by the customary external resetting knob or key 7c, Figs. 1, 2, and 3. Said back part 1 of the register-casing is provided internally with the movable part, (not shown,) from which said actuating-stud 5 projects through the customary slot or suitable opening in the back plate, and means for retracting the same, including an amplifying-lever 1), Fig. 3, connected with a retracting-spring. (Not shown.)

The other parts of the register mechanism include a pair of frame- pieces 6 and 7, Figs. 3 to 6, inclusive, perpendicular to the back plate of said back part 1 and rigidly attached thereto in the Working register. l/Vhen said moving part Within the back part 1 is pulled through the medium of the customary operating back and said stud 5, its motion is transmitted primarily to a pawlcarrier 25, which rocks on an aXis concentric with that of the trip-register wheels at. Said pawl-carrier t carries a working pawl a, which interacts with a ratchet-wheel a, Fig. 3, and is further supported by a bracket or bridge-piece 8, fixedly attached to said righthand frame-piece 7 and a spring-pressed detent-pawl a is pivotally attached to said right-hand frame-piece 7 and interacts with said ratchet-wheel u to prevent retrogression, the whole constituting a pawl-and-ratchet device of known construction.

The step -bystep movements of the ratchet-wheel a are transmitted directly to the units-wheel of the trip-register wheels a, with which said ratchet-wheel a is concentric, and by a train of spur-gearing, represented at 9, in Figs. 3, 4, and 6, to the units-wheel of the totalizer-wheels b, which is thus made to rot ate synchronously with the units-wheel of the tripregister in the registering operation.

Motion may be transmitted from wheel to wheel in the totalizer by any known or improved means. Intermittent spur gear carrying or transmitting means of known construction is represented at 10, 11, and 12 in Figs. 3 to 6 inclusive.

To provide for resetting the trip-register numeral-wheels a backward to Zero independently of the actuating mechanism, said ratchet-wheel u is connected with the unitswheel of said numeral-wheels a through the medium of the first gear of said gearing 9, a stop-wheel o adjoining the same in the form of a reversed ratchet-wheel and a notched clutch-wheel w adjoining said stop-wheel, which are loose on the shaft 2 of said numeralwheels a and are normally coupled to said units-wheel by a tumbler a, a stud-pin on the latter being interlocked with the notched periphery of said clutch-wheel by a spring 13, stretched from said tumbler to a stud within the units-wheel. The tumbler e is attached to the units-wheel by a pivotal screw 14, and a spring-pressed detent-pawl f, attached to said units-wheel by a pivotal screw 15 interacts with the notched periph cry of the clutch-wheel w to limit the rotation of the numeral-wheel in the resetting operation to the backward direction. The registering motion of said numeral-wheels a is transmitted from wheel to wheel by suitable intermittent spur-gearing, to which the present invention more particularly relates, interacting with like clutch-wheels w, tumblers e, and detent-pawls f within the sev eral numeralavheels. The elements of said intermittent spur-gearing connecting the numeral-wheels a with each other include a side ring 16, fixedly attached to the left-hand side of each numeral-wheel having a numeralwheel of higher value to its left and constructed with a transmission device 17, preferably in the form of two spur-teeth united with each other at the bases of the teeth, the interdental space being coincident with the customary notch 17, the whole being convenientlyintegral with said ring 16. A pinion 18, herein termed a trip-pinion, arranged to interact with said transmission device at each transmission-point, is preferably and conveniently of known construction in the form of a small spur-wheel of twelve teeth and a star-wheel of four teeth coincident with four of the teeth of the spur-wheel, both of one diameter, the two being integral with each other and the teeth of the spur-wheel portion about twice as wide as those of the star-wheel. The other elements of the transmission-gearing are spur-rings 19, connected by spiders with the clutch-wheels w of those numeral-wheels which have a numeralwheel of less value at their right, and thus rendered movable only in the registering operation, these spur-rings being in constant mesh with the spur-wheel portions of the respective trip-pinions 18.

In the registering operation motion is transmitted through the units clutch-wheel w or its equivalent to the units-wheel and to the transmission device 17, which it carries, the latter revolving in the direction indicated by the arrow y in Fig. 6, and when it con tacts with the spurwheel portion of the contiguous trip-pinion 18, as in Fig. 6, this trippinion is turned on its axis, and an adjacent tooth common to the spur-wheel portion and the star-wheel enters the interdental space 17 of the transmission device 17 and passes out of contact with the trip-pinion with the parts in the relative positions shown Q1 Fig. 4, the contiguous spur-ring 19 and the clutch wheel to and its appurtenances of the tens wheel to which said spur-ring is attached having been meanwhile turned, and therewith the tens-wheel itself, so as to indicate the registration of the tenth fare. It will be understood that registering motion is transmitted from wheel to wheel throughout the series in like manner.

For resetting the numeral-wheels a to zero said shaft .2, which is common to said wheels, is rotatable by means of the resetting-key 7c, which is screwed into its right-hand end, and is also movable endwise by means of said key. In the registering operation it occupies the position in which it is shown in full lines in Fig. 3 and is locked against rotation by a notched collar 20, fast on the shaft, and an interlocking stud 21, attached to said yokepiece 8, for example. It is held in this position through the medium of a lever 22, pivoted to a lug 23 on the right-hand framepiece 7 near the lower edge of the register by a tensile spring 24L, stretched horizontally from the upper end of said lever 22 near the top of the register to' the left-hand framepiece 6. A locking-bolt 25 is attached to said lever 22 near its spring end and interlocks with a flange on the pawl-carrier t when the shaft .2 is pulled outward to unlock the shaft for the resetting operation. The pawl-carrier t is thus locked against registering actuation when the resetting-shaft z is unlocked, and vice versa. The resetting positions of the shaft .2 and the parts movable therewith, so far as the latter are shown in the figure, are indicated by dotted lines in Fig. 3.

Within each of the numeral-wheels a or immediately at the left of each numeral wheel the resetting-shaft 2 carries a stud 26, Fig. 5, which during the registering operation is out of contact with the numeral-wheel to which it is appropriate and parts turning therewith, but in the resetting position of said shaft is located in the plane of the notched inner end 27, Figs. 4 and 6, of the appropriate tumbler e and interacts therewith in the resetting operation, serving first to turn the tumbler on its pivot 14, so as to unlock the numeral-wheel from the clutch-wheel w and then transmit motion from the shaft ,2 through said tumbler to the numeral-wheel itself to which the tumbler is pivotally at tached. WVhen the numeral-wheels c are thus turned backward to zero, the transmission devices 17 carried by the several numeralwheels to which they are attached contact with the trip-pinions 18 in the manner represented by Fig. 4. The resetting movement of each numeral-wheel and the parts turning therewith is represented by the arrow 2,

To prevent the trip-pinions 18 from being turned by the transmission devices 17 in the resetting operation, and thus to adapt these trip-pinions to constitute effective zero-stops or the several numeral-wheels other than the numeral-wheel at the left dogs 28 are pivoted on a rod 29, parallel to the supporting-rod 30, on which the trip-pinions turn and are so located as to interact with the spur-wheel teeth of said trip-pinions in such a way as to freely permit the rotation of the trip-pinions 18 in the registering operation, but to resist and prevent their rotation by the impact of the transmission devices 17 therewith at the end of the resetting operation. To prevent injury to the trip-pinions 18 by giving them this function, the strain due to the interaction of the dogs 28 therewith is distributed by a suitably-shaped lateral extension 31 on each dog, contacting with a pair of the star-wheel teeth of the trip-pinion 18 in each zero position of the latter, as best shown in Fig. 5. Such dogs need to be spring-pressed, and said horizontally-stretched tensile spring 24 by which the resetting-shaft e is retracted and is held in its retracted position for the registering operation is conveniently so located with reference to said dogs 28 and the backs of the latter are so shaped that said spring contacts sidewise with the dogs, as in Figs. 4 5, and 6, and holds them to their work in an effective manner.

The left-hand wheel of the numeral-wheels a, which may be the hundreds-wheel, as l shown in Figs. 1 and 3, or the tens-wheel or a 1 wheel of a higher denomination, is provided I with a zero-stop ring 32, Fig. 3, on its left- I hand side having a suitably-located peripheral notch, and a stop-dog 33 interacting with this notch is pivoted to the inner side of the left-hand frame-piece 6 and pressed against the periphery of said zero-stop ring and into said notch by a spring 34 stretched therefrom to a stud on said frame-piece 6. A simple and effective provision is thus made for stopping said left-hand numeral-wheel at Zero in the resetting operation if it has been moved from zero by registrations without interfering with the continuous rotation of the wheel in the registering operation.

If the series of numeral-wheels be extended, the left-hand wheel may obviously have a zerostop, preventing its rotation beyond zero in either direction. It will be understood that the number of the numeral-wheels a may be increased to any desired extent or may be reduced to two wheels, as in some fare-registers, and other like modifications will suggest themselves to those skilled in the art.

The herein-described combinations of parts for connecting the numeral-wheels a with the actuating mechanism through the medium of the clutch-wheels w and for unclutching the same preliminary to the resetting operation are more fully described in substance in my specification forming part of Letters Patent No. 800,565, dated September 26, 1905, and constitute part of the invention claimed in that specification.

The combination with the endwise-movable resetting-shaft z of the lever 22, retracting-spring 24, and locking-bolt 25, as hereinbefore described, are more fully described in my specification forming part of Letters Patent No. 834,118, dated October 23, 1906, and form parts of the invention claimed therein.

All the parts and combinations of parts hereinbefore described or shown in the accompanying drawings that are claimed in said previous specifications, or either of them, are hereby disclaimed in favor of said previous specifications.

Parts omitted in the drawings forming part of the present specification are or may be of constructions shown and described in said specification forming part of said Letters Patent No. 834,118.
