Abstract: 5396. Kuntzen, O., and Kahle, A. March 4. Fares, registering.-In fare indicators and registers for vehicles, the customary arrangement for throwing the ratchet mechanism out of action while the vehicle is travelling over the distance corresponding to the "basic" fare is rendered unnecessary by the substitution for the usual rotary pointer or indicator of a figure arc a, which is constantly moved forwards one division by a ratchet mechanism, after a given section of the course has been covered, and at the end of its movement is returned to the last division corresponding to the basic fare. The construction described is illustrated in connection with German measures and currency, the basic fare being taken as 50 pfennige for a distance of twice 400 metres, and an additional charge of 10 pfennige being made for each further distance of 400 metres. Under these conditions, the number 50 is shown twice on the "pfennige" arc a, but if the distance corresponding to the basic fare of 50 pfennige amounted to three times 400 metres, the number 50 would be shown three times on the arc a. The 00 on the arc a stands in front of the inspection opening until the fare indicator is thrown into gear by turning the shaft v in the direction indicated by the arrow in Fig. 3. The disc v<1> then depresses and releases the lever w, so that the lever d can be turned by a spring to cause the pawl e to move the ratchet f forward by one tooth, whereupon a second ratchet f<1>, which is locked to the ratchet f by a screw f<2>, actuates a pawl a<2> on the arm a<1>, which turns the arc a until the first 50 appears at the inspection opening. When the vehicle has traversed the first 400 metres of the distance corresponding to the basic fare, a cam or its equivalent actuates the lever d, and the arc a is moved forward to expose the second 50. In the next throwing into gear after 800 metres has been covered, the 60 appears, then the 70, and so forth. After the arc a has been moved forwards from 90 to 00, an arm a<4> imparts, through the lever t, the pawl t<1>, and the ratchet g, a movement which shifts the " marks " are b from 0 to 1. As soon as the arc a has reached the end of its travel, the pawl a<2> is disengaged by a spring from the ratchet f<1> and rides over a guide q while the arc a is being returned or moved back by a spring. The contact of the end of a pawl r with a pin s on the arm a<1> prevents the arc a from being returned to its initial position, and causes the second 50 to appear at the inspection opening, so that the fare indicator is shifted from 1À40 to 1À50 marks. The "tens" arc c is actuated in due course by the engagement of a pawl u on the ratchet g with a ratchet c<1> as soon as the "units" arc b is moved forwards beyond 9. In the forward movement of the arc b from 9 to 0, a pin k<1> on the detent k drops into a groove g<1> in the ratchet g, which, together with the arc b, is then returned to its initial position. On the completion of the journey, the arcs a, b, c are brought back to zero by a further rotation of the shaft v. The disc v<1> causes the disengagement of the pawls and detents of the ratchets f, f <1>, and the disc. v<3> the disengagement of the pawls and detents of the ratchets c<1>, g, so that the discs a, b, c may be returned or moved back by springs.
