Title: Improvements in or relating to taximeters
Inventor: HAUPT WILHELM
IPC: G07B13/00
Filed: 1955-01-28
Abstract: 772,797. Taximeters. KIENZLE APPARATE GES. May 9, 1955 [Jan. 28, 1955], No. 2642/55. Class 106 (3). In a taximeter having multiple tariff rate devices driven by mixed time and distance drives provision is made for an automatic tariff change after the elapse of a predetermined time or distance or a combination of both. The fare indicating means are driven by means of a shaft 61, Fig. 1, by a time drive comprising gears 68, 64 or by a distance drive comprising gears 14 or 15, 16 or 17, 67, 66 and 65, the distance tariff ratios being altered by the selective engagement of gears 14-17 by intermediate gears 10, 11 carried on levers 8, 9 pivoted at 6 and adjustably connected to cam levers 4, 5 operated by cams 2, 3, 3a on the setting-spindle 4. The automatic tariff change mechanism comprises a sliding lever 22 carrying a toothed wheel 26, Fig. 2, driving a reduction gear train 28, 29, 31 whose last member 31 has a disc 37 screwed adjustably on its face by means of a slot 38 and screw 49. In the initial " Hired " position with the first tariff engaged by intermediate gear 11 by selection of cam-lever 5, the slide 22 is brought to its left-hand position by means of its connection with an arm 20 depending from the lever 5 and the toothed wheel 26 engages with the toothed end 57 of a shaft 55 driven through gears 58-60 by the time or distance drive whereby the disc 37 is slowly rotated in an anticlockwise direction. At the expiry of the predetermined time or distance delay period, a lug 39 on the disc 37 lifts a lever 40 to free a projection 42 thereon from engagement with a stepped portion 43 of the lever 22, whereby the lever 22 moves to the right, breaking the driving connection 57, 26 and the disc 37 repositions itself in the starting position with its stop 35 abutting a stop 36 under the influence of a spring 34. The slide 22 has a bent-over lug 51 adapted to engage, when the slide is in the left-hand position, with an arm 50 of a lever 45 having a lower arm 46 secured to a link 47 in turn secured to an arm 20 depending from the cam-lever 4. In the left-hand position of the slide 22 the lug 51 through this linkage prevents the cam-lever 4 engaging the cam surface 3 but on moving to the right the lug 51 frees the arm 50, thus permitting the lever 4 to move under the influence of the spring 44 to engage the higher tariff gears. Simultaneously the movement of the slide to the right rotates arm 20 and brings cam lever 5 out of engagement with the cam, the spring 54 controlling the lever 5 being weaker than the spring 44. On returning the meter to the " For Hire " position the cam surface 2 operates a cam lever 42a to lift the projection 42 clear from the portion 43 of the lever to permit disengagement, if necessary, of the cam lever 5.
