Specification of Letters Patent.

Patented Mar. 4, 19

1' all whom it may conceive Be it, known that 'I,'VVILIIELM Gr s-rm BRUHN," a citizen of the German Empire, residing at Berlin, in the Kingdom of Prussia, German Empire, have invented new and useful Improvements in Taximetcrs. of

which the following is a specification.

'- combined indicating apparatus to be effected b one single slide;

The accompanying drawings show by 3 way of example a form vof apparatus constructed in accordance with the invention.

Figure 1 is a front: elevation of the com- .bined indicating" apparatus. Fig. 2 is a similar View with the cover plate removedf Fig. 3is a bottolniplanand liig.'-4.- is a, rear elevation. 7

The cover'plate-lzf is formed with two upperfand two lower apertures. The fare is exhibited behind the two upper apertures, bythe threenumeral disks 2', Z, ant i lower apertures by thefthree disks l' and The extras are indicated behindytheztwo' 0. The dishes 701 m n 0 are respectively fiziedion the spindles 73 7, m 21, 0. Upon the spmdtes it and 7c are secured the ratchet wheels and y respectively. The feed or operation of the ratchet wheel .1: whereby the fare isiincreased by a. unit of price, for example 10" p fennige, is effected 'autonnitically in be known way after a given distance ha n traveled or after a given period of time has elapsed. The operation of the ratchet-wheel g whereby the extras indicated are increased for example by units "of 25 pfen'nige ata time, is effected in the knownflvayb '.'a knob or other manually operable device (not shown) usuallysituated at the back of the app'aratusand turned by the driver.. The decnnal,transm ss on from the spindle i of the. first indicating disk! to thespindle l and from this spindle to the spindle m iseficcted in the known way by notched count-mg wheels, and the decimal transmission from the spindle is to' the spindle n and from the latter to the spindle 0 similarlyefiferted.

way:The middle spindles and n are. adapted to slide axially so thatthe notched counting wheels of the right hand spindles i In comeout of engagement with the rors responding notched counting wheels upon the middle spindles Z and '21- i and the notched counting wheels on the spindles? and n come out of engagement with the notched counting wheels upon the spindles m 0 The middle spindles Z and n are now to zero by means of heart shaped cams, while the left and right hand spindles are moved back into the'zero or starting position by means of springs. For this purpose there is fixed on the left and right hand spindlesi'espefctiwelyia toothed wheel m k 0*. Theset-ooth'ed wheelsgear respectively with spring barrels M iv o. The spring barrels contain slip springs, that is to say springs havingtheir innerend fixed to the axis of the barrel while their outer end rubs on the cylindrical wall of the'barrel; If such a spring rbtirrel is .turnedinthe direction in which the springis'coiled the spring will be taken around with it. owing to the friction between the outer end'of the: spring-and'the wall of the barrel, and the spring will therefore wind up. \Vhen this tensionattains a certain amount, 'thespring will slip on the inside of the barrel in the spring barrel is releasedit-will be rotated back by the spring until the latter is slack. The disks 1'. 1a,.ls, oQcarry respectively pins if In I and 0 which in the backward rotation of the disks under the action of the spring barrels, strike againststops m k a. Thestops m3 and 0 are fixed, while the stops 1' audit? are formed (it-spring levers, which in the forward feed of the disks '2' l. are moved aside by the pins 2 is and there fore allow their respective disks i It: to make any desirednumber of revolutions, whereas they only allow their disks to turn backward until the pins 11* Zr" strike against the levers 1' b. Upon the middle spindles l Hitll't respectively fixed heart shaped alns 'l ii. The. axial sliding of the middle spindles a middle zeroizing of the heart shaped cams; n is ctl'ected as follows. l'n setting the apparatus to the disengaged or inoperath-e position, a lever (Figs. 3 and l) is turned ina directionm the arrow. This lever imparts its motion by a spring 44o a slide 1- continued turning of the latter. If the mounted at the underside of'tlie apiiz'iratns; The slide r moves the catch pawls no and 11 out of engagement with the ratchet Wheels.

m and 3 so that the isks a" and 7t: can be turned back into their initial positionby the spring barrels and 7:.

To the slide r is fined a wedge cross arm 9" which in the sliding movement of the slide 7' passes under forks Z n which enga go in notches in the spindles Z n respectively. Therefore the movement of the slide 7 has the ciiiect of sliding the spindles Z "c". To the slide 7* is connected a slide 3 prorided on the other or the bottom piste. This slide 8 has two noses s" and s which, when the slide is moved to ward the right, engage in the heart shaped cams Z and n and set the same to zero. Owing to the fact that the lever 7:) which act-mates the slides r and s is not connected rigidly with the lever T but only through. the medium of the spring 9 the important acl vantage is attained that the projections .9 and are allowed a certain time to reach the deepest portions 01 the heartshaped cams Z and n, and thatif a projection s or 8 should happen to come exactly upon the point of the heart, shaped cam Z or n, so that further movement of the slides r and 8 toward the right would be prevented, no breakage of any part- Whatever could be therefore occasioned, and the only effect would be that the spring Q Would be stressed to a correspondingly greater extent. As however the slides 'r and s, owing to the intel-position of the spring 9, are not compelled to follow the lever 72 at once, but can follow it during thelvv'hole of the time in which the lever is moving toward the right, it will be seen that even in no}: a case the zeroizing of the heart shaped cams Z and n would be effected as a rule even if somewhat 'tardily.

If the eirparatus is put very quickly into the disengaged or inoperative p'osition, and is immediately thereafter pub very quickly into the engaged or operative position, it.

'may be possible under some circumstances owing to the rapid motion of the projections s and 8 toward the right that a very rapid rotation of the disks Z-and n will be produced. It, might occur thatin the return motion of the projections s and .9 the disks Z and n owing to their momentum, would retain the rotation imparted to them, and

thereby move away again from the zero position; In ordento prevent this, pins Z 01,

noes-ens right, he levers Z n are released more into their engaging position. ii new in the further movement; of the slide e toward the ri 'ht, the disks Z and are ti'irned to zero,

ment just described for preventing running of the middle tlisl's 7 l o t gaged position and immediately the" autoriatically and that, according to tht sition' which the disks Z and it have a.-

position the return of the cl "1" to the zero position occurs in the one or her tiirec r recti'ons of rotation, the levers Z n" are pushed aside by the pins Z? or 6 and come.

notches with the pins Z Ye when the disks have been moved to the zero position. This from. previously known arrangements wherein, for the purpose of zeroizing, the

turned in the same direction, namely in the direction or feed, so that it is necessary to ward and to "remove a etc before the disks can be fed forward again in further use I claim:
