ALPHONSE JEAN-BAPTISTE EDOUARD BARRAS, 0F PARIS, FRANCE.

TAXIMETER.

To all whom it may concern.'

Be it known that I, ALPHONSE JEAN-BAP- 'risrE EDOUARD Dennis, a citizen of the Republic of France, and resident of Paris, F rance, have invented new and useful Improvements in or Relating to Taximeters, which improvements are fully set forth in the following specification.

This invention relates to taximeters with multiple tariffs of the kind described in my application Ser. No. 369,118 of April 19, 1907, in which the figure drums are intermittently rotated and return to their original positions upon the raising of the flag and in which the main driving shaft is caused to register one or the other of the tariffs by the preponderating movement produced either by a clock or by the vehicle, the clock being stopped in the distance tarilf at the desired moment by a suitable device.

The invention particularly relates to the following improvements: 1. A device iinparting the intermittent rotary movement to the figure drums. 2. A device for returning the ligure drums to a starting point. 3. A device for driving the .figure drums for supplements.

The improved apparatus is illustrated by way of example in the accompanying drawing in which similar reference characters denote corresponding parts and in which- Figure 1 is a perspective view of the apparatus; Fig. 2 a front view thereof; Fig. 3 a plan view thereof; Fig. 4 a sectional plan view through the ligure drums and the means for driving the latter; Fig. 5 a rear view of the apparatus and Figs. 6 to 12 are details.

In the drawing A denotes the casing of the taXimeter, 28 a spindle borne therein and to which in the manner described in the above named prior application, the preponderat- .ing movement produced either by a clock or by the vehicle is transmitted. Rigidly mounted on the said shaft 28 is a pinion 29 which is in meshing connection with a wheel 35 that is loosely mounted on a spindle 36 (Fig. 5). The wheel 35 has attached to it one end of a spiral spring 37, the other end of which is tiXed to a piece 3S that is rigidly mounted on spindle 36. Under the action of the spring 37, the spindle 36 has the tension to always revolve in a certain direction. On the outside of the spindle 2S disks 39 and 40 are rigidly secured (Figs. 3, 5 and 6) which are provided with suitable notches directed inward and displaced against one an- Speccation of Letters Patent.

other. To the spindle 36 on the other hand a disk 41 is keyed which is provided with stepped projections 42, 43, 44 and 45 (Figs. 3 and 5) arranged alternately on its two faces. In the example shown the disk 41 is in such a position that the projection 42 thereof is engaged in one of the notches of the disk 89 (Fig. In this position the disk 41 is locked until the notched disk 40 in its rotation with the spindle 28 presents one of its notches to the disk 41 which under the action of the spring 37 is caused to suddenly escape and to rapidly execute a fraction of a revolution together with the spindle 36. In this manner an intermittent rotary movement is imparted to the spindle 36.

Rigidly secured to the spindle 36 is a pinion 47 adapted to transmit the intermittent movement of the spindle 36 to the figure drums in the following manner: Upon a spindle 36 slidably borne in the frame A and which loosely carries pinions 49, 52, 55 and 55 and which we will call the pinion spindle, a wheel 48 is mounted which is coupled with the pinion 49. The pinions are suitably secured on the spindle 86 to prevent their relative displacement. Upon a spindle 61 parallel to the spindle 36 the figure drums 50, 54 and 54 are loosely mounted of which is designed for cents, 54 for dollars and 54 for tens of dollars and which as in the prior application are formed with teeth. The pinion 49 is adapted to mesh with the teeth of the pinion 50 (Figs. 1 and 4) and to thus transmit an intermittent rotary movement to the latter recording the cents.

For the recording of dollars on the drum 54 the following arrangement is made: The drum 50 has also two longer teeth 50 (Fig. 1). The pinion 52 is provided with alternately recessed teeth 52. The longer teeth of the drum 50 are adapted to .meet one of the teeth 52 of the pinion 52 and to cause the latter to advance two teeth. Between the drum 50 for cents and the drum 54 for dollars a toothed disk or wheel 51 coupled with the latter is provided, the teeth 51 of which are adapted in a certain position of the pinion 52 to mesh with the teeth 53 of the latter and to thereby give the drum 54 the recording movement.

The recording of tens of dollars on the drum 54 is-eifected in the following manner: The pinion 55 `is composed of two parts 55 and 55 which are fixed on the same Socket (Fig. 4) and of which 55 has also alternately recessed teeth 55. The disk 51 has two longer teeth 51 which during the recording are adapted to mesh with the teeth 55 ot the pinion 55 and impart to the latter a fraction ot rotation. At the side ot the drum 54; another toothed disk or wheel 56 is provided the teeth of which mesh with the part 55 of the pinion 55, so that the rotation of the pinion 55 is transmitted to the drum 5st through the medium ot the part 55 and disk 56.

The pinions 19, 59., 55 and 55 are retained in contact with the respective drums by means of a lever 59 that is xed on their common spindle 36. The other end of this lever slides on a spindle 20 (Figs. 1 and 2) which we will call the flag spindle Fixed upon the tlag spindle is a cam 96 that is adapted upon the raising of the lag to act against a. roller 97 carried by the lever 59 and to thereby cause the displacement of the pinion spindle 36, whereby the pinions are shifted out of meshing connection with the drums (Figs. 1 and 2).

A finger 60 rigidly secured to the slidable spindle 61 is arranged in the path of a cross pin 62 projecting from a disk 59 which is loosely mounted on the spindle 61. T o this disk one end of the spiral spring 58 is secured, the other end ot which is tixed to the trame A. On the outside of the spindle 61 a, disk 63 is xed which is provided with a notch 64C (Figs. et and 7) and which normally rests against pin 65 projecting from the frame A. A spring 66 which at 66 is secured to the frame A (Figs. 1, 3 and t) acts against the end of the spindle 61 and tends to displace the latter in the direction from right to left as indicated by dotted lines (Fig. L1). This displacement however, only becomes possible when the notch 64 ot' the disk 63 is brought in line with the projection 65 so that the latter can project into the notch.

Secured to the end of the slidable pinion spindle 36 which is opposite to the spring actuated end of the drum spindle 61 is an arm 9S the lower end of which projects in line with the spindle 61 and which on the displacement. ot the pinion spindle 36 acts against the spindle 61 and tends to shift the same from left to right. This displacement releases the disk 63 from the projection 65 permitting the disk 59 to turn under the influence of the spring 58 and to thereby impart rotation to the spindle 61. This rotation is transmitted to the drums by means of spring blades 56 projecting radially from their circumference and pins 57 arranged in their path and tixed to the spindle 61. Thus the drums upon the raising of the tiag are caused to return into their initial position.

On a spindle 92 below the spindle 20 of the flag, two drums for supplements, for

cents and 94 for dollars are loosely mounted. These drums are actuated by springs 101 and similar to the iirst named ligure drums are provided with teeth. Loosely mounted on the tlag spindle 20 are pawls S2 with sockets 100. These sockets have central recesses 100 through which pins 99 fixed to the spindle 20 project outward. The pawls SQ which at their free ends are notched are caused by means ot spring S8 one end ot which is secured thereto and the other end to the spindle 92 to engage with the teeth of the respective drums tor the supplements and lock them in position. Upon raising of the iiag, the pins 99 acting against the sockets 100 cause the pawls to swing upward releasing the drums 85 and 94, which under the influence of their springs 101 will tend to rotate.

On a spindle 7S which by any suitable means may receive an interniittent movement, anchors 79 are secured (Figs. 1, 9, 9 and 10). Each ot these anchors consists of a disk provided with stepped ` flanges 86, 80 and Sl. The part S6 of the 'tlange is in retreat relatively to that of the part Set and S0 and in line with them. The drums S5 and 94;, each have one tooth 87, which is longer than that of the rest ot their teeth and which is adapted on coming in contact with the part S6 of the liange to prevent the drum from making more than one revolution. One end of the tlange S0, Si has a slope from the outside inwardly to torm a curve which when the anchor is revolved in the direction ot the arrow a1v engages a tooth 81 ot the corresponding drum and gives it a turn in the direction of the arrow y (Fig. 9) to the extent of one haltl a tooth. The 0pposite end of the Harige 80, 8st is curved in the reverse direction, so that when the anchor by suitable means is caused to return into its initial position, this curved end engages another tooth S5 of the drum (Fig. 9) and causes it to turn in the same direction to the extent of another hallC a too-th. The anchors are so positioned on the spindle 7S relative to one another that during a quarteil of a turn given to the spindle 93 in a certain direction one of them will operate one drum as for instance, the drum S5 for cents and during a quarter ot a turn in the reverse direction. the other anchor will operate the other drum as the drum tor dollars. Each anchor may be rotated to O only, never to 180, so that the drum for cents is not able to influence the drum for dollars or vice-versa. The part 79 has a notch 79 (Figs. 11 and 12) for engagement with the teeth of the drum when released until the longest tooth 87 strikes the projection S6.
