Abstract: 6347. Lake, H. H., [Bruhn, F. W. G.]. March 15. Indicators, "engaged" and like.-Relates to indicators and fare registers for public vehicles. A cam spindle 3, which can be turned in one direction only, can be set in any of four positions corresponding respectively to two rates of 'fare by ' distance,' ' charge for waiting,' and ' disengaged.' In the first two positions, the lever 32 is placed so that the fare register is driven from the vehicle wheels through either of the pairs of gears 35, 37 or 36, 38. In the other positions the odometer is out of gear ; but when the vehicle is 'waiting,' a cam on the spindle 3 rocks a lever carrying a star and toothed wheel so as to bring a special register into gear with clockwork and the fare register out of gear. The star-wheel then acts on a spring pawl, and advances the waiting' time register at intervals. When the lever 5 is in the position shown in Fig. 5, the apparatus is to be driven by distance, and the lever 29 normally presses a spring on the balance-wheel 30 of the clockwork ; but when, as just described, the spindle 3 is set for 'waiting,' a cam 55 strikes a lever 56 and moves the lever 29 by a pin 57 so as to start the clock. When the fare is to be by time, the lever 5 is raised to a vertical position, and a pin 31<1> rocks the lever 31, which, by means of a pin 33, places the lever 32 in position to throw the odometer out of gear. At the same time, the pin 27 falls and ceases to hold the lever 29, by means of a hook 28, in position to put a brake on the clockwork. The clockwork therefore starts and drives the fare register. A 'disengaged' flag or indicator 1 is mounted on the spindle 2, which is connected with the spindle 3 in the manner described in Specification No. 20,772, A.D. 1897. This flag must always be turned down before the clockwork can be set going. Fig. 12 shows the way in which the 'tariff' is indicated to the passenger. The disc 45 is fast on the spindle 3, and exhibits through a sectorshaped aperture in the casing one of the four announcements 'waiting,' 'disengaged,' ' Rate I,' or ' Rate II.' A loose disc 46 carries the two announcements ' By distance ' and ' By time,' showing through an upper sector-shaped aperture. A spring 47 tends to bring the latter announcement into view, but is prevented by a detent lever 49 having a pin 51 engaging a notch in the disc until the lever 5 is turned up, when a cam 48 frees the detent. In subsequently setting the disc 45 to the ' disengaged ' position, a pin and pawl connection behind the two discs is effected, during a quarter of a rotation, to return the disc 46 to the position shown. The spindle 6 is fitted with two ratchetwheels, with oppositely-turned teeth, and a cam which acts in conjunction with detents engaged by pins and a projection on the cam 22 mounted on the spindle 2. The arrangement is such that, when the lever 5 is down, the signal 1 is free ; if the signal be turned down, the lever 5 is locked until it is again turned up. If the lever 5 is partially turned up, it is locked against return, and the signal is locked during the movement. While the lever 5 is up, the signal can only be partially raised, whereupon the lever 5 can be turned down and the raising of the signal completed. The object of this mechanism is to oblige the driver to return the apparatus to the initial position when changing from time to distance indicating and vice versÔ, and to prevent partial movements of the setting-apparatus.
