To all whom it may concern:

Be it known that we, JOHN F. OHMER and WILLIAM G. ()RTH, citizens of the United States, residing at Dayton, in the county of ontgomery and State of Ohio, have invented certain new and useful Improvements in Taximeters; and We do declare the following to be a full, clear, and exact description of the invention such as Willenable others skilled in the art to which it appertains to make and use the same,'reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates tov new and useful improvements in taximeters and is an improvement of the device shown, and described in the co-pending application of Ohmer and Bridenbaugh, filed June 3, 1912, Serial No. 701,208. F

The objects of .the present invention are several, principally; to provide means whereby the flag shaft and setting mechanism are returned to a normal position during the operation of taking the printed statement from the machine thereby dis pensing with one of the manual operations of the machine of the application above referred to; to provide means whereby the printing mechanism can only be operated 1 when the flag shaft and setting mechanism position; to p rgo'vide an is in the stopped bell-ringing mechanism improved form of which eliminates the erator becoming confused when operating the device; to provide new and improved means for. resetting the counters to zero;

and to providimeans which prevents the possibility of-the machine becoming disorganized when a printed record is taken by the inspector.

These and other objects of the invention will be more particularly described and pointedout in the specification.

Throughout the specification and drawings, similar corresponding parts.

The frame wor/c Mounted on a suitable base (not shown) looking at Fig. 1 is' a left end plate 1,, a right end plate 2; a left division plate 3 and a right division plate 4. The end and division plates are joined by lugs 5 while the division plates themselves are joined by an upper bar 6 and a lower frame member 7. Extending between the upper bar 6 and the member 7 are frame plates 8. 9 andlO which support the counters and the various actuating means there;

' ('ozmtcr and their actuating means. F igs. 1. 2, 4 and 9.-Journaled in theframe S. 9 and 10 is a shaft 11. Mounted on-this shaft 11 is a units and tens wheel 12 which the line e-e of Fig.

shaft, locking reference characters. denote plates represents cents, a dollar wheel 13 and a shaft 37 journaled to an oscillating shaft 18. The shaft 18 is journaled in the frame plate 9 and the division plate 3 and carries an arm 19 adapted to engage a four arm cam 20 mounted on a shaft 21 journaled in the end plate 1, division plate 3 and the end of the shaft 11. The shaft 21 carries a timing drum 22 in operative relation with a pawl 23 carried by the arm 19 and shown in dotted lines in Fig- 9 and in Fig.1. The drum 22 permits the cam 20 to actuate the arm 19 when the vehicle on which the taximeter is mounted has traveled a sufficient distance or has consumed time equivalent to the minimum fare charge. This expedient is well known in taximeter construction and needs no further description here. The shaft 21 is the main drive shaft for the counter and may be driven from a clock, as shown and described in the application hereinbefore referred to, or it may be driven from the wheels of a vehicleas follows: As will be seen from Fig. shaft 21. on the outside of the end plate 1 is provided with a ratchet 24, adapted to be engaged by pawls 25 mounted on a gear 26 freely journaled on the same axis as the shaft 21. The gear 26 is in mesh with a pinion 27 attached to a gear 28 mounted on a lever 29 the pivot or axis of .which is alined with shaft 21. The said lever 29 is adapted to be rocked by a cam 30 carried by shaft 31 of the setting mechanism hereinafter described. Vl'hen the cam 30 rocks said lever 29, the gear 28 is placed'in mesh with a gear 32 which in turn meshes with a gear 33. The gears 32 and 33 are mounted on pivots 34 and carry worm gears The worm gears 35 mesh with worms 36 on. aw in top and bottom bear.

ings 38 and the end of a shaft39 journ'aled in a bearing 40. The connection between the gears 32 and worms 36 form no part of .the present invention. It constitutes means whereby the counters are driven irrespective of the direction of travel of the vehicle and is more completely described in theapplication "above referred to. The-shaft 37 is connected to the shaft 39 through clutch members 41 which form part of an obstruction indicator mechanism more fully shown and described in the application ,hereinbefore referred to. Thesha ft 39 is connected in a well known manner to the wheel of the vehicle on which the taximeter is placed bv W hen said vehicle wheel is rotated, the counting wheels 12, 13- and 1 1 will be actuated in accordance with a predetermined rate of fare which is determined by the ratios of the gears in the'train previously described. Also mounted on the shaft 11 is acounting wheel 42 for indicating the amount of extra charges. This counting wheel and its actuating mechanism are more fully de- 2, the end of the meansfof a fiexibleshaft (not shown).

scribed in the application hereinbefore referred to. Referring briefly. thereto, the "said wheel is operated by a pawl 11 piveted on a shaft 11 on the end of which shaft is located'a cam 11. 'erated by a one revolution turn to count one digiton-said wheel 12, see Fig. 1. The .pawls 10, mounted cipro'cated by the cam 20, before referred to, through the aid of a spring 43 which depresses said pawls after having been pre-. viously-elevated by the cam 20, said spring 13 being connected to one end of an arm 44: on the oscillating shaft 18. The said pawls 16 are elevated out of an operative It willbe understood that the termset ting mechanism includes the means whereby theoperative relation is established tween .the' counters and the actuating mechanism thereof. 1 The counting wheels 12, 13,

are geared to two sets of printing wheels 16 and 17 through the The wheels, 46 are adapted to print the ticket, while the wheels 17 are adapted to print the record. The wheels 46 are mounted upon the shaft 19, while the wheels 47 are mounted on ash-aft 50,-see Sheet 1. The shaft -19. is mounted -in the frame plates 8, .9 and 10, and shaft 50 is mounted in counter frame 7", see Figs. 1 and 1, frame 7 being shown in dotted lines in Fig. 4. The type wheels aflcotiperate with the platen 51in printing the tickets, while the typewheels 47 cooperate with the'platen' 52 in printing the record. The platens 51 and 52 are mounted on frames 53 slidably inountedin bearings area the end plates 1 and will beseen from Figs. 1, 4 and 5. The frames 53- are provided with rollers 55 adapted to be engaged by cams 06' carried The cam 11 is opon the frame 17, are reagency of gears 48;.

14 and 12, which are of the indicating type,

upon a printing shaft 57 journaled in the end plates 1 and 2 and the division plates 3 and 4, see Fig. 5. The printing shaft 57 carries a gear 58 in mesh with a pinion 59 mounted on a pivot 60, as is shown in Fig. 3. The gear 59 is provided with a crank (31 by means OflVVlllCll the printing mechanism is actuated, see Fig. 1.

The setting mechanism, which is more fully described in the before mentioned application, has three positions; first, a. nor-.

nial position in which. the parts are shown in the drawings, Fig. 5, and in which position the machine is placed when the vehicle is for hire; second, a position when the shaft 31 of the setting mechanism has been givena quarter of a revolution from said first po.

However. at or about the time the segment gear 87 meshes with the segment gear $13. the drum 110 rides out of the path of the projection 111 therein unlorhing the setting mechanism. The drum llil... therefore. prevents the setting: merhanism being returned to a normal position by any means other than the printing nieehanism.

Figs. 1, J, I. um! .*"1 \.t the end of the returning mownienl of the setting mechanism to normal. the counters ronsistin a' of the wheels 1'2. 1 ll and 1'. are returned to a normal position. Mounted on the setting shaft. 31 is a dish 11; which earries a pawl 113 adaptml to engage a ratehet 111. freely mounted on the shaft 11. This mechanism is mount ed adjaeent to the Frame plate 10. The en gagement hetween the pawl 1115 and the ratchet 111' is eontrolled by a ram 115 extending from an arm 115 mounted on a pin 11h. see Figs. ('1 and T. The cam 11;") surrounds the shaft 31. The ratchet 111 is attarhed to a gear llT which is in mesh with w an idler pinion 11$ mounted on a pivot 119 and attaehed to an idler gear 12th see Figs. 1 and h. Said gear 1:20 is in mesh with an idler gear 1'21 mounted on the pin 116 and in mesh with a near 122 secured to the shaft 11 on whieh the counting wheels are mount ed. The shaft 11 is provided with a plurality ot' ratehets 123 of well known form. one for earh counting wheel, see Figs. 1, l and 12v Each ratehet 123 is provided with a recess 'lll adapted to receive the ends of individual pawls 125 which are under the inlluen e of springs 126. The said pawls 123 are mounted on the ratehets of the counting wheels. \Vhen the counting wheels are in a normal position. the pawls 125 he in the recess 121. and when said counting wheels are actuated during the process of wanting, the. said pawls ride out of said re resses, the ratchets 123 remaining stationary. When the setting mechanism and the shaft 31 are moved out of their normal position or to a for hire position, the pawl 113 is isengaged from the ratchet 114 by the \Vhen the shaft 31 is returned position, the cam 115 permits to engage the ratchet 114 and to rotate the shaft 11 through the agency of the interposed gear, through one complete revolution. During this one complete revolution of the shaft 11 all of the ratchets 123 will, at one point or another, pick up the pawls 125 and return the counting wheels to normal position. The ratchet 114 may be provided with an alining pawl 127 under the influence of a spring 128, see Fig. 7. At the time the counting wheels are re turned to normal position, the timing drum 22 is also returned to normal position by the shaft 11, said shaft 1.1 being provided on its left end with a ratchet 123 engaged by a pawl 125 which are identical with the ratchets and pawls of the counting wheels. Said pawl 125 of the timing drum is mounted upon a disk 129 on the shaft 21 upon which the timing drum 22 is mounted. Sec Figs. 1, 9 and 12. The timing drum will, therefore, be returned to a normal position concurrently with the counting wheels.

the pawl 113 positively hold said timing drum in their normal position, the following stops are provided. Each of the pawls 125 is provided with a projection 130 adapted to be engaged by movable [)HWlS 131 mounted on a sleevc E32 journaled on a shaft 133, see Figs. 4 and 8. The shaft 133 is journaled in the division plates 3 and 4,which may be the inking mechanism shaft shown and described in the hereinhefore mentioned application. mechanism is moved from a for hire position to a hired position and the counters placed in operative relation with their actuating mechanism, the pawls 131 are moved out of the path of the projections 130, thus permitting the cormting wheels to be actuated by a cam 134 on the setting shaft 31, see Figs. 1 and 8. The cam 134 is in operative relation with an arm 135 attached to the sleeve 132. The cam 134 moves the pawls 131 out of the path of the projections 130, while the spring 136 at tached to the arm 135 moves said pawls into the paths of said projections 130. The timing of the cam 134 is such that the pawls 131 wil1 be moved into the path of the promal positions.

It will be noted that if the inspector should inadvertently move the flag crank 31 he second or to the hired position before he elevates the pawl 66, the setting \Vhcn the setting I thus and otherwise the following lock is provided. Mounted on the right end of the shaft 31 is a disk 143 which carries a cam-latch 139, see Figs. 1 and 3. This cam-latch 139 is pivoted to the disk 113 at 142 and is under the control of a spring 141. The said cam-latch 139 cooperates with a pin l3S on a lever 137 pivotcd at 140. A spring 141 is provided which exerts an upward influence 011 the lever 137, which is adapted to engage the pawl 66 and to lock the tooth '72 in the recess 73 of the ratchet 74. When the setting mechanism is moved from a normal to hired position, the pin 138 on lever 137 rides upon the cam portion of the latch 139 until said pin rests upon the outer edge of the latch. Vhen in thi. position, the lever 137 looks the pawl 66 thereby preventing the inspector operating the printing mechanism by elevating the finger. member 77. When the machine is actuated by the travel of the vehicle upon which it is carried and the setting mechanism is moved to its third or stopped position preparatory to taking a printed record, the pin 138 will fall behind the cam-latch 139 and will travel behind the same during the time the setting mechanism is being moved from its third to its normal position.
