Fig. 7 is a sectional elevation taken The pawl 23 is held to duty in engagement loo 5o on the line 7-7 of Fig. 1, looking in the diwith the ratchet 2t by a small coiled spring rection ot' the arrow, andV looking from the 3, held in a socket 2 carried by the pawl-car- 53eme rier 26 and bearing against the back of the pawl.

An alarm is sounded each time the pawlcarrier 26 is oseillated by providing the end of the pawl with a boss 4 which as the pawl is pressed outward in passing` backward over a tooth of the ratchet 2t bears against a widened end 5 of a bell-hammer 55 mounted on a pivot 56 on the base-plate A. The dropping and engagement of the paWl with the succeeding tooth suddenly releases the bell-hammer and allows it to spring forward under the tension of its spring 551l and forcibly strike the bell I; such forward movement of the bellhammer being limited by an abutment 7 projecting from the base-plate A, as seen in Figs. 3 and 6. After the bell has thus been struck the widened, or as it may be stated, lengthened end 5 of the bell-hammer returns in position in time to meet the heel of the pawl 23 which then bears against it and slides along its face with sufficient friction to prevent any overmovement of the trip and permanent registers by any sudden return of the pawl on this its feeding movement, which as is com mon is caused by the force of a spring, not herein shown.

The permanent register E, as before stated consists of the usual series of adding wheels representing` units, tens, hundreds, thousands, dac., carried by the shaft 25 in the frame 35 and having the usual carrying pinions. This permanent-register carrying-frame 35 is hinged upon a pin 36 at its outer side to the back plate A, see Fig. 7 so that the frame, adding wheels, actuating pawl-carrier 2G, and bevel pinion 22 may be rocked bodily toward the back plate A, to disconnect said pinion 22 from the gear 2O whereby the permanent register is temporarily disconnected from the trip-register and thus render the trip-register capable of being returned to Zero independent of the permanent register. So far as some of the features of the present invention are concerned other means of disconnection may be employed.

The re-setting device or mechanism by which the trip-register is returned to the zero position or initial starting point without disturbing the permanent register, consists in the main of a revoluble shaft 39, in gear with the trip-register and a means for disconnecting a hold-back or lock from the trip-register whereby it is rendered free to move by means of said shaft.

In the present practical embodiment of this invention, the revoluble resetting shaft 39, is mounted in suitable bearings 40, projecting from the base-plate A of the register and is in gear with the index t of the tripregister by a pair of imiter-gears 3S (see Figs. 1, 2, and 7) one fast to the end of said shaft andthe other fast to the bevel gear 20,so that, as the index t' is moved step by step in registering the fares collected, the shaft 39 will be correspondingly moved.

The backward movement of the trip-register is in the present case prevented bythe action of the hold-back pawl 10, engaging Vwith the ratchet 24, through the geared connection between the trip and the permanent registers. In order, therefore, to relieve the trip-register from the infiuenee of such a pawl or other pawl having a similar function but different location, it is requisite to temporarily disconnect such pawl or lock from the trip-register. This is effected in the present instance by rocking the permanent register frame 35 so as to temporarily disconnect thc pinion 22, from the gear 20, whereby the gear 20, and index t' of thetrip-register are wholly disconnected and freed both from the permanent register E and from the hold-back pawl 10. The particular means for accomplishing this disconnection, as herein shown, consists of the slide F, Figs. 2, 5, and 7, which is provided with means adapted to rock the permanent register frame 35 by an inward movementand to restore said frame by a reverse movement of said slide. This slide F is provided at opposite ends with hubs 1S, 19, which embrace and slide on the shaft 39. Said slide F is moved in one direction by the inward movement of a sleeve g, having a thumb Wheel g at its outer end and mounted on the shaft 39 and to move longitudinally with respect thereto but adapted to rotate thelatter through a pin 1, fitting a slot in the sleeve as in Fig. 1. The reverse or return movement of the slide F is had by a spring 1G coiled about the shaft S9 between the hub 19, of said slide and one of the bearings 10, Figs. 2, 5, and 7.

The slide F is provided with an inclined slot 12, see Fig. 5, that is engaged bythe end of a stud 11, projecting rigidly from the frame 35, see Fig. 7, in such manner that when the slide F is pushed inwardly as just described, the slot will force the stud toward the back plate A, and hence carry the frame 35' with it and so disengage the gear 2O and pinion 22. The end of the stud l1 is grooved to receive a vertical guide 13, see Figs. 5 and 8, projecting from the back plate A, and is thereby steadied in being moved by the inclined slot 12 of the slide F.

In operating the re-setting device, as thus far described, the thumb-wheel sleeve g, is pushed inwardly thereby also pushing the slide F inwardly against the power of the spring 16. As soon as the slide has been moved sufficiently to have disconnected the permanent register from the trip-register, the shaft 39, through the thumb-wheel g', may be rotated backward to return the index ft' to zero.

To obviate the necessity of holding the slide F, forcibly inward during the rotation of the resetting shaft, 39, and to provide a guard compelling the complete return of the tripregister to zero and preventing the premature return of the slide F before such return is effected the slide F, carries one part of a retaining device consisting of a pawl 42 pivoted thereto and adapted to engage with the IOO ICS

other part of the retaining device consisting of a circular flange 41 on the outer surface of the gear 20. In whatever position the tripregister may have been moved during the usual operations of the register, when the slide F is pushed inward through the thumbwheel sleeve g, the pawl 42, will be moved to engage with the flange 41 of the gear 20, and the slide be thereby retained in such inward position, whereupon the thumb-wheel g and shaft 39 may be readily rotated and through the miter-gears 38 revolve the index i backward to zero position. Vhen the zeroposition is reached, means are provided for freeing the pawl 42 from the circular retaining flange 41 so that the spring 16 may be free to return the slide 39 outward to its normal position. Thus the retaining flange 41 is not continuous but has a recess 6 formed in it at a point and of suflicient width to permit the pawl 42 to pass outward from alignment with the flange 41, when the index t' arrives at the zero position as in Fig. 1. The same surface of the gear 20 is also provided with another fiange 41 arranged to catch the pawl 42 should the slide F be moved only partially inward, in which case, the parts are so arranged as hereinafter described that the shaft 39 cannot be rotated, and thus compels a full inward movement of said slide.

To prevent the premature rotation of the shaft 39 and consequently that of the gear 20, should the slide F be not moved fully inward, said slide F may carry a fixed detent 17 Fig. 2, arranged in such position with respect to the complete movement of the slide that it will take into the teeth of the gear 20 and remain therein should said slide be only partially moved inwardly, but if it be moved to its limit of inward movement the detent 17 will pass to the inner side of the teeth of said gear and have no effect to prevent its rotation and that of the shaft 39.

At the same time the slide F is moved inward preliminary to the rotation of the shaft 39 to reset the trip-register to zero another detent represented by a yielding pawl 15 carried by the inner end of said slide F, see Figs. 1,and 7, is moved longitudinally into engagement with the teeth of the gear 2O and remains in engagement so long as the slide is in said position, which pawl 15 in the normal position of the parts and during the step by step movements of the trip register lies out of engagement with the gear 20, as in Fig. 2. This pawl l5 is arranged, when engaged with the gear 20, to yield, by its spring 15"L and slot 15b that embraces the end of the shaft 39, to permit the free backward rotation of the gear 2O but will firmly lock it against movement should it be attempted to move it in the reverse direction. The return of the index t' to the zero position is determined and fixed by a pawl 14, see Figs. 1, 2, 4, and 5, carried by the frame ofthe register and engaging with a tooth or notch 8 in the thumbwheel sleeve g, such notch being elongated to suit the longitudinal change positions of thesleevewithoutdisengaging the pawl. The stopping of the trip-register at the zero position may also be additionally insured by an arm 64 (see Fig. 1) adapted to meet a projection 64C, see Fig. 7, on the under side of the gear 20. This arm 64 is pivoted to a post 7L and is mounted to yield in one direction by a spring 64a so that should the trip-register be moved to register one hundred fares and over or in other words be moved to have made a complete rotation or over the projection 64C may pass the end of the arm 64.

From the foregoing, it will be understood that, in order to return the trip-register to zero position, it is simply necessary to move the slide inwardly to the proper position to relieve the trip-register of the hold-back pawl 10 and sufficiently to free the fixed detent 17 from the gear 20, and then rotate the shaft 39 until its further rotation is stopped by the pawl 14. The retaining device (represented by the pawl 42 and flange 41) simply serves to hold the slide in position and to prevent its return until and only when the complete resetting of the trip-register has occurred. It will also be noticed that the resetting shaft 39 is constantly' coupled to the trip-register so that no coupling for connecting and disconnecting the two are necessary. Any attempt at moving the trip-register through the shaft 39 without first moving the slide F inwardly is prevented by the hold back pawl 10 through the gearedconnection with its ratchet 24 which securely locks said shaft 39 against such movement.

The register herein shown is also provided with a direction indicator H adapted to be changed in position when the slide F is moved inwardly the same as in said patent, but as this forms no part of the present invention and does not modify the novel features thereof no further description is necessary.
