ABRAHAM WEISINGER, OI NEWARK, NEW JERSEY, ASSIGNOR 1'0 'U NI'IED STATES TAXIHETER CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY.

Application filed January 12, 1924. Serial No. 685,916.

To all whom it may concern:

Be it known that I, ABRAHAM WEISINGER, a citizen of the United States, and a resident of Newark, county of Essex and State of New Jerse have invented certain new and useful Improvements in Taximeters, of-

which the following is a specification.

This invention relates to an lmproved taximeter which is constructed to operate smoothly and efiiciently and which is in duplicate for the respective indicator drums and which is adapted to have all the drums returned or re-set to zero by the operation of a single return handle.

The object of the invention is to provide such a meter which is accurate in that the parts are positively released and returned to the starting position and in which the respective units are easily assembled and operatively connected.

The invention is illustrated in the accompanying drawings in which Figure 1 is a front View of one unit of the taximeter and Fi re 2 is a sectionon line 22 in Figure 1 looking in the direction of arrow a. Fig ures 3 and 4 are views similar to Figure 2 but with the partsin different positions. Figure 5 is a section on line 22 in Figure 1 but looking in the direction of arrow 6. Figure 6 is a view similar to Figure 5 but with the parts in different positions. Figure 7 is a longitudinal section through Figure 1 and showing part of the next unit in dotted outline. Figure 8 is a detail section of the parts shown in Figures 5 and 6.

In the construction shown the frame com-- posed of the plate 10, the-bearing plate 11 and the bearing plate 12 forms a support for the unit for registering and is suitably secured in the casing of the meter (not shown) as will be evident to one skilled in the art and the holes 13 receive screws by which the frameis fastened.

The finger 14 is the usual reciprocating arm operated by mechanism that is well known and is driven from the wheel of the means of vehicle. After a pre-determined amount of freely on the shaft 21 which shaft, however, is rotatable by other means as will be described hereinafter. The spring 22 holds the pawl 18 on the ratchet. The ratchet is secured on the jack shaft 23 which extends through plates 11 and 12. A retaining pawl unit and as it is necessary to go from tens to hundreds, it is customary to lace a fixed 0 to indicate the digits w ich' is not 0 anged as the normal fare is in multi les of 10. The tens however, are indicated y the drum 27 and the next succeeding drum must operate one tooth at each complete revolution of the drum indicating tens so that the meter can register to $9.90, for instance.

To return the drum when it is released, I place a pinion 32 which is provided with a spring 33 fastened to the pinion and the stud 34 on which the pinion reciprocates. The pinion 32 is in mesh with the pinion 35, and the pinion 32 is mutilated by a cutting away a part as at 36 So that excess pressure on the spring 33 is prevented.

' The next succeeding unit is operated by a rocker arm 37 secured so as torock the shaft 21 to which-it is secured as by a pin 38. At every complete revolution of .the

drum 27 and necessarily of its shaft 33, the

cam 39 moves from the position shown in Figure 5- and in its rotation shoves the rocker arm 37 over until it snaps over the nose 40 and the spring 41 operates it and the shaft 21 to which the nextunit connected by having its rocking lever 16 secured to the shaft by the pin 42 or its equivalent. I

When the cam40 moves the rocker arm 37 it rocks the shaft 21 and the rocking lever 16 of the next unit far enough to move its pawl 18 over one tooth of its ratchet and the' next drum advances one figure. The rocker arm of the said next unit is not operated except by its own cam 39 as the shaft 21 is divided by a loose connection 43 as will be seen from Figure 7 in which figure the rocking lever and rocker arm of said next unit are shown in dotted 0utline.

When the meter is to be re-set, the fla arm or handle 44' rotates the shaft 45 whic has a finger 46 which is disposed so as to bear on the studs 47, 48 and 49 of the pawl 18, rocking lever 16 and pawl 24:. respectively, in each unit so that all the ratchets are relieved of these and the spring 33 in each unit forces the mutilated pinions 32 to rotate the pinion 35 and drums are all rotated back to zero, being halted in each unit by its rocker arm 37 which acts as a stop.

It will be seen from this description that the repeated rotation of the drums as in a long ride will not strain the return springs 33 as the spring can not be wound to excess as the open place 36 will prevent any further rotation of the mutilated pinion beyond the position shown in Figure 8.

Excess throw of the pawl 18 is prevented by the stud 50.

Minor changes can be made in the construction without departing from the scope of the invention.

I claim:

In a taximeter having a drum, a rocking lever, a pawl rotatable with the drum and a retaining pawl normally engaging the ratchet, a re-setting device including a shaft and a finger on the shaft disposed so as to engage the lever and both pawls to simultaneously swing them all to inoperative position.

' In testimony that I claim the foregoing, I have hereto set my hand, this 14th day of November, 1923.

ABRAHAM WEISIN GER.
