-vlfhen the lever 13 is in its lower position, with the dog 17 engaging the ratchet-Wheel. 1, the rotation of the ratchet-wheel causes each tooth as it passes under the dog 17 to raise the dog and give a correspondingv movement to the lever 13.

T he ra tcliet-v'heel 1 is turned by meehan ism controlled by the distance traversed by the vehicle, or it the vehicle at rest during hire the iworli of rotating the ratchet-Wheel is talen'by a clockwork. An air- Jump (not shown) gives an air-pressure impulse at each revolution ot' the road-wheel to an air-piston 100, which. operates a lever 101, carrying a dog 102 and retracted after each impulse by a spring 103. The dog 102 ,operates the ratchet-wheel 101i, whence motion is conveyed by toothed wheels 105 106 to the prismatic shaft 107, carrying toothed Wheel 108, which may be previously set to engage any one of the graduated set of tooth-wheels 10.() on. shaft chosen, according to the diameter oll the road-wheel. By beveled gear 111 and 112 motion passes to shaft 113 and Wheel 114, which in the position illustrated in Fg. 7 meshes with wheel 115 on shalt 122, worm 123 engaging with Worm-Wheel 124 on shaft 125 or' ratchet-wheel 1. Wheel 114 is shittable by means ot fork and cam 121, moved by exterior lever 1410, and can be moved out of gearvith 1 15, orifmo ved farther will clutch with wheel 116 and give a dili'erent ratio of transmission through wheel 117, or by removing -wheel 11.11 in the other direction it clutches With Wheel 118, giving another ratio of transmission through wheel 119. l/Vlieel 124 is loose on shaft 125 and carries a pau'l 126, engaging a ratehetwheel 127, fast to said shaft 125. vWhen the Vehicle is at rest, the WheelV 12/1 ceases to revolve; but a clockwork 128, acting through wheel 12,9, loose on. sha'lt125, drives the latter through a pawl 130 and ratchetswheel 131, fast to the shaft 125. rEhe shaft is thus when the taxoineter is in action normali r driven by the transmission mechanism from the road-Wheel, :and the ratchet-wheel 131' overruns the pau/'i 13G, but when the vehicle stops or nieves so slowly that the clockwork rating exceeds the pace of the vehicle the clockwork drives the shaft 125, and the ratchet-wheel 127 overruns the pawl 126.

On the lever 13 are two springressed levers 22 59, pivoted at 23. f he ever 22 is double-armed, the lower arm being marked 24. The upper end of lever 22 ends in a tooth 27, and in the raised position of lever 13 the tooth 27 extends under and lifts out ot' action the pawl 535. 4

W'hen the lever 13 is moved toward the ratchet-wheel 1, the tooth 27 allows the pawl 35 to engage a ratcliet-segment 31, integral with an arm 30, pivoted at 37, the said seg- -ment being simultaneously engaged by the ears against a lined abutment 40 and is thus prevented from engaging a ratchet-wheel 25, 7o

mounted on an aXle 42. This ratchet-Wheel 25 serves for driving one ot' theV counting- Wheels, and the purpose of the segment 31 is to keep the lover 22 out ot engagement Wi th the said. ratchet-wheel until the minimum- 75 fare distance has been traversed or an equivalent amount ot time has been consumed.

The rotation ol" the ratchet-Wheel 1 by the means already indicated causes the lever 13 to be rocked on its pivot 11, and each move- 8o ment of the said lever toward the segment 31 causes the latter to be displaced by means of the tooth 27, the segment being retained in its new position by the pawl During the return movement of the lever 13 under the 85 action of the spring 21. the tooth 27 trips over a certain number of teeth on the segment.

T he tooth 27 after a certain number of rocking movements rides ofil the lower end of the segment 31; but the adjustment is such 9othat at the end of the rocking movement by which this is accomplished the lever-arm 24 is still on the right-hand eide ol the stop 4G. During the next'rocking movement, however,

yhe said lever-arm. clears the said sto so i that the lever 22 is enabled to rotate on its pivot 23 under the influence of the spring by which it is actuated. The ratchetfwheel 25 is thus engaged by the lever-arm 24, and the abutment 10 then serves to prevent the said zoo lever-arm from becoming disengaged from the said wheel by vibration or the li ie. T he distance to be traversed or the amount of time to be consumed. before the counting mechanism is started can be controlled by 105 adjusting the segment 31. Assuming, Jfor instance, that the Wheel 1 rotates through an angle corresponding to one tooth-space While0 the vehicle traverses a distance of two hundred yards (which shall be called the unit 1 1o not disengaged therefrom until n 1 d isplace- 1 1 5 ments of the segment have been produced by the rocking of the lever 13. 1n the example illustrated the segment 31 is so adjusted that the counting mechanism is operated when a distance equal to twice 'the unit distance has 12o been traversed b the vehicle, the segment 31 being rotatec? through an angle corresponding to tWo of its tooth-spaces by one rocking movement of' the lever 13. This adjustment is such that when the vehicle starts .i z 5 the tooth 27 engages what may be called the last tooth-space on the segment, as shown in Fig. 2. The movement of the lever 13 while the 'first unit distance is being traversed causes the tooth 27 to he disengaged from 130 f i die the segment 31'; but the disengagement of the said tooth takes place while the lever i3 .is moving away from the segment and too late to allow the arm 24 to clear the abutment 40. During the next movement of the lever 13, however, the said arm is enabled to clear the said abutment, and thus cornes into engagement with the ratchet-Wheel 25 at the moment when the minimum-fare distancethat'vis to say, twice the unit distance-has been traversed. The parts then occupy the positions indicated in Fi 3, so that subsequent movements of the ever 13, due to rotation oi the ratchet-wheel l, cause the ratchet-Wheel 25 to be operated. by means oi the arm 24. li more than twice the unit distance is to be traversed by the vehicle be fore the counting mechanism. is started, the adjustment of the segment 31 suitablj-,r altered by rotating a cam-dish 33, mounted on pin 39, which serves as abutment ier an arm 78, integral with the arm 30, b lwhich the segment is supported. The earnalisli: is ro tated by a suitable key and is accessible for that purpose only when the case is opened. The ratchet-wheel 25 is iixedly connected with a nnmberavheel 26, the numerals oi which may represent cents, the axle l2 oit the said ratchet-wheel being stepped in a suitable bearing situated at the center the ring 49, already referred to. The one end of the said axle is supported by suitable bearing formed in a bar 43, extending across tl e number-wlieel 26. A springdicx le is arranged Within the ring 49, and one end of the sgring contained in the said box is inserted into a slot in the axle i2 in auch a manner that the rotation of the axle with the Wheels 25 and 26 by the lever 22 is not prevented hy the said spring, but that the latter rotates the said axle and wheels back to their original positions, When the lever-arm 24 is disengaged from the Wheel 25. The rotation. of the axle Li2 bythe said spring is limited by a catch 47, which is iixed to a spring 48, Figs. 5 and 6, and extends into thepath. of a projecing pin 46, fixed to a disk, integral iwith the Wheel 25. The said catch 47 is so shaped that it can be tripped by the pin 46 during the rotation ofthe Wheel 25 by the le-A ver-ar1n 24. The numerals representing dollars are placed on a wheel 50, which is iixed to a hollow axle 54, mounted on a sleeve 56, which surrounds the axle 42.

` A ratchet-Wheel 55, iixed to the axle 54, is adated to be operated by means of a tooth. at t e end of the s ringressed lever 59, already referred to, t e sai lever 59 being connected at 23 with the rocking lever 13. A Erojection 60 at the free end oi the lever o9 ears against the circumference oi the disk 45, and the diameter of the latter is such that the tooth on the said lever can only engage the wheel when the said projection 60 extends into a recess 62, with which the disk 45 is provided. @ne Wall of this recess is in clined in such a manner as to displace the projection and disengage the lever 59 from the Wheel 55 when the latter has been rotated through an angle corresponding to one tooth s ace. The Wheel 55 is therefore rotated t'irough this angle duringeach complete reve elution of the wheel 25.

A spring-box 52, carried by a support 51 and contaminal a spring 53, surrounds the axle 54, one enc oi thespring being attached to the latter in euch a manner that the axle 54;, with the Wheels and 5U, is rotated back to its original position w ien the dering mecl'ianisniis disconnected from the counting mechanism. The rotation ol the Wheel 5U by the spring 53 limited by means of abutment 53, fixed to the said wheel and adapted to come into contact with a ysuitable stop.' two spring-actuated 'oell-crit1ilklevers 65 and mounted on an axle @3,iio1riiailylock the 1atcliet-wlieels 25 and 55, respectively, the said levers being disengaged from the said wheels during the movement of the lel vers fi, il, and i3 by means of a projecting rod 65, whichis to the lever 3 and ahnte against the curved arms 67 and (37 oi the bell crank levers. The reliability oi the counting mechanism is thus further increased.

JJlien the-lever arm 24 clears the abutment e0, the movement of the lever 22 rearward projection ol the tooth 27 to engage a ratchet-Wheel 28, Fig/i, so that the subsouent rocking oi' the lever i3 causes antic oclrwise rotation to be imparted tothe said ratchet-wheel 23. The latter adapted to drive a seriesl oi co1itrolling-Wheels 2Q, 29, and 292. Clockwise rotation of the ratehet- Wheel 28 is prevented by means oi a pawl 64.

ln order to readjust the counting rneonanism inthe positon shown in Fig. 1 when the levers 4, 8, and 13 have been .moved into their position of out oi action by means oi' the cam 3, the pawl 55 must bedisengaged from the segment 31 and the lever 22 must be so operated that during the movement or' the lever 13 toward the segment the tooth. 27

.clears the latter and abuts against the said pawl. For this purpose Vthe leverarin 24 is provided with. a curved projection 33, so arranged that wlien the said levenarm engages the Wheel 25 the said rojection abuts against a pin 32, fixed to the ever 8. The operation of the latter by means of the cam 3 andlever 4 therefore causes the lever 22 to be operated in the manner desired. i
