Abstract: 12,621. Kirby, C. H., and North, R. B. May 31. Fares, registering.-A taxameter adapted to be driven by a clock or vehicle and provided with a minimum-fare device, a device for registering and totalizing extra charges, a snap action and a totalizer for the fare dials, and means for simultaneously disengaging the operating-mechanism, declutching the clock, and returning the fare dials to zero, is operated by a spring-controlled lever m, Fig. 2, mounted on an arbor l and actuated from the vehicle wheel by a flexible connexion. Motion is conveyed from the arbor l, driven by pawl and ratchet from the lever m, through gear-wheels w, x, y, to a wheel z secured to a sleeve 23, Fig. 6, loosely mounted on a shaft 18, and provided with a pawl engaging a ratchet 25 carried by a sleeve 26, loose on the shaft 18, the other end of the sleeve having a pinion 27 gearing with a clock-driven wheel 40, Fig. 3. The sleeve 26 carries a lug 44 adapted to drive a single-toothed wheel 21 mounted loosely on the shaft 18 or on a countershaft 20. In the latter case, the lug 44 engages with a pin 48 carried by a loose disk 50 on the shaft 18, Figs. 6, 8, and 9, which disk carries a pin 49 engaging in a slot in a gear 17 secured to the shaft 8 and engaging a gear 19 on the shaft 20. A snail cam 47 on the shaft 20 engages with a spring 46 and communicates a quick movement to the wheel 21 and thus through a wheel 22 to the fare disks. Where the wheel 21 is mounted on the shaft 18, the parts are arranged as shown in Fig. 10. The pence disk is carried by a sleeve 52 frictionally mounted on the shaft 53 of the wheel 22. The shillings' disk e, mounted concentrically with the pence disk, is driven by the wheels 54, 55, and a single-toothed wheel 57 engaging with a wheel 58 frictionally mounted on a sleeve 60 to which the shillings' disk is secured. The initial fare is indicated on lowering the flag and rotating a disk 10 into the position shown in Fig. 2, a pawl 11 thereon rotating a gear 5 loose on a shaft 6, through ratchet teeth 12. The gear 5 rotates the shaft 18 and thus the fare disks through gearing 7, 8. A totalizer 4 for fares is driven through a bevel-gear 1, Fig. 6, mounted on the shaft 18. The fare disks are zeroized when a spindle 9, Fig. 2, is rotated by a roller on a projection 67 of the disk 12 striking a lever attached thereto. The spindle 9 carries two levers, bearing rollers, or one lever provided with two rollers, 65, 66, Fig. 3, which engage with heart cams 61, 62 mounted on spindles 52, 60. The rotation of the flag causes the lever to depress through an arm s the lever m and thus prevent the actuation of the taxameter. The interlock between the flag and the spindle 9 may consist of a lever having a pawl which normally bears against a lever on the flag. The rotation of the disk 10 is limited by a spring push 13 engaging in notches 14 in the disk 10. A clutch throwing the clock into gear is actuated by a cam on the shaft 9 when the flag is put to ' engaged.' Extra fares are indicated when a shaft 74, Fig. 3, is rotated by an external handle, a sleeve 77 carrying a pence disk k being driven by spur gearing therefrom. A shillings' disk is driven by a single-toothed gearing, and snap action is ensured by a star-wheel 89 and a spring 90. A totalizer 88 for the extra fares is operated by bevel-gearing and a ratchet clutch from the shaft 74.
