Abstract: 6592. Bruhn, F. W. G. March 28. fares, registering and checking.-Exterior handles,. actuated by the driver of a vehicle, are connected by special means to the mechanisms for putting the fare indicator into or out of action, setting it to a particular tariff, actuating the flag arm, winding the clockwork which increases the fare when the driver has to wait, and for indicating additional charges. The invention is applicable to the type of apparatus described in Specification No. 20,772, A.D. 1897. Fig. 2 is an elevation of the mechanism, which is on the inner side of the back wall of the indicator, and Figs. 3 and 4 show details. The flag arm b<2> is carried by a head b<1> attached to a shaft b, the bearing of which is partly conical. On a square part b<6> of the shaft, a plate b<7> fits so that it can slide somewhat along it, and a pin b<12> in the shaft passes through a slightly larger hole in two disks b<9>, b<10>. The bearing is kept water-tight by means of a spring b<14> acting on the disk b<10> and on a disk b<13> fixed to the shaft. An annular space b<15> is provided for a lubricant. The handle c<5>, by means of which the indicator is put into or out of action, is attached by a pin c<6> to a shaft c, the bearing of which is'also partly conical, and is kept tight by a spring c', preferably acting on a conical bush c<8> somewhat loose on the shaft. To the shaft is attached a disk c‹, formed partly with ratchet teeth, which are engaged by pawls c<13>, c<14> during a part of the revolution of the disk, to prevent backward rotation. The disks b<7>, c<9> are recessed so as to interlock the shafts b, c, as described in the Specification cited above. A pawl b<16> on the disk b<7> has teeth which engage a projection c<17> on the disk c<9> and prevent the partially raised flag-shaft from being lowered again without first setting the fare indicator in action. A disk c<10> attached to the disk c<9> has recesses which are engaged by the similarly shaped end of a spring retarding-lever e<18>. The end of the shaft c forms a bearing for a disk c<12>, connected by a spring c<15> to the disk c<9>, and movable relatively to that disk through an angle limited by a pin c<20> and a recess c<19> in the edge of the disk c<12>. The disk c<12> carries pins c'‹ acting on a star-wheel f<1> on the shaft f, which places the fare indicator into action, and is provided with a device (not shown) tending to retain it in definite positions. By these means, accurate movement of the shaft f is obtained independently of the accuracy of movement of the handle. The bearings of the shafts d, e of the clock winding and additionalcharge handles are similar to that of the shaft c, the conical plug c<8> being however omitted. In the end of the shaft d is a square or rectangular hole d<6> to receive somewhat loosely the square end of the winding-shaft. The shaft e is provided with a ratchet-wheel e<5>, acted on by a spring pawl e<6>, which is arranged, as in the prior Specification, to prevent actuation of the additional-charge mechanism when the flag is raised. Pins e<7> on the disk engage a star-wheel g<1> on the shaft g, which puts the mechanism into action. A device is provided which tends to retain the star-wheel in definite positions. The pin and star-wheel arrangements may be replaced by equivalent devices, such as pins and forks.
