Figure 3 is an enlarged side elevation partly The turning of the set register mechanism is 55 2 2,128,900 controlled by the rotation of the gear 22 on the shaft l1 which gear meshes with the gear 23 forming part of the turning train for the regis ter mechanism, all as fully disclosed in Patent No. 1,344,898 referred to. After a` registering op eration the coins drop into a reservoir or cup 24 from which they may be readily withdrawn by in ward swing of the door 25. For the purpose of our invention we provide a base housing 26 below the fare box housing part 3 and preferably this base is adapted to be readily attached to or detached from the fare box struc ture. Referring particularly to Figs. 3, 4, and 5 the base at its top has apertured seating lugs 15 21 through which screws may be extended for se curing the base to the bottom of the fare box structure, Extending through the base at the front part thereof, and parallel with the shaft l1 and its other terminal connected by conductor 52 with one terminal of the motor whose other terminal is connected by conductor 53 with the contact brush 42, the contact drum 4D having electrical connection with the fare box frame work and being therefore grounded. A conduc~ tor 54 connects the contact plunger 41 with the contact brush 42, the contact disk 44 being grounded to the fare box framework. The cir» cuit including the current source, the motor, the conductor 54, and the switch mechanisms 44 and 41 constitutes a starting circuit for the motor, while the circuit including the current source, the motor, and the switch parts 42 and 48 constitutes the main or operating circuit for the motor, the contact plunger 41 being normally disconnected base is mounted an electric motor 32 which may from the contact disk 44 and the contact brush 42 being normally in engagement with one of the insulator segments 4| of the contact drum 4D, so that normally both circuits are open. 20 Describing now the operation, when coins or tokens are deposited in the fare box, the collector, after inspection of the tokens in the inspection be suspended from the top wall of the base compartment 2, swings down the dumping lever is a countershaft 28 which at one end carries a 20 pulley 29. The pulley is shown outside of the base and engages a belt 3i) which passes around a sheave 3| secured to the shaft I1. Within the 25 in any suitable manner, the motor shaft 33 ex tending a distance below and at right angles to the countershaft 28. The connection between the shaft may be by way of a worm 34 on the motor shaft and a worm wheel 35 on the counter 30 shaft or any other suitable driving connection may be employed. The rotation of the countershaft by the motor will be transmitted by the belt 3D to the driving shaft I1 for the evaluating and registering moeh 35 anism of the fare box. Depending from the top wall of the base 25 is a boss 36 which at its front end carries a verti cal shaft 31 which supports a worm wheel 33 for engagement by a worm 39 on the countershaft 28. Secured to the underside of the worm wheel con» centric therewith is a metallic contact drum 48 9 against the force of the spring 55 tending to 25 hold the lever in its upper position. Upon such movement of the lever the coins or tokens are dumped into the evaluating mechanism and at the same time the rotation of the contact disk 44 brings its cylindrical surface into contact 30 enga-gement with the contact plunger 41 for clo sure of the starting circuit through the motor and the motor is started. The downward and return movement of the dumping lever will keep the starting circuit closed for a sufficient length of time for turning of the contact drum 40 by the motor to move the insulating sector away from the contact brush and to bring the con tact drum into electrical engagement with the brush so that the main or operating circuit for 40 a holder 43 on the boss 35 rearwardly of the contact drum, the holder being of insulating ma terial or otherwise-arranged for insulation of the contact brush from the boss. With the arrange the motor will be closed for continued operation of the motor until the next insulating segment is brought under the contact brush for opening of the motor main circuit. The ratio of the gear ing between the motor and the countershaft 28, and the ratio of the gearing between the counter shaft and the worm gear 38, and the number of insulator segments in the contact drum, can be readily calculated for the desired length of time 50 ment described it is evident that, when the motor is operating, the contact drum will be turned for alternate electrical engagement with the brush or of operation by the motor after starting thereof by operation of the dumping lever, the time length being usually made such that, under ordi insulation therefrom by the segments. Referring to Fig. 3 the shaft 8 which carries the nary service of the fare box, each period of op eration of the motor will have resulted in sorting and registering of the dumped coins or tokens. Should any coins or tokens be left unregistered after one period of operation of the motor, they will be taken care of during the next period of whose contact circumference is interrupted at regular intervals by insulator segments 4|, three such segments being shown. The contact drum fi ò is engaged by a contact brush 42 extending from dumping lever 9 has mounted thereon a contact disk or cam 44 which may be located within and adjacent to the side wall of the housing part 3 through which the shaft extends. Against the inside of said wall is secured a block 45 of in~ 60 sulating material in which a metal cup 45 is in serted for a contact plunger 41 urged outwardly by a spring 48, the outward movement being limited by the engagement of' the cup edge by the shoulder' 49 on the plunger. The Contact mem - ber 44 on the shalt 8 may be in the forni of a cylindrical disk slabbcd off on one side to leave a clearing or depression 58 into which the con~ tact plunger 49 normally extends out of con tact with the disk but contacted by the cylindri 70 cal part of the disk when the shaft 8 is turned by downward swing of the dumping lever 9. Fig. 5 shows the circuit connection between the motor and switches. A source of current 5|, such as a storage battery, has one terminal 75 grounded to the frame of the fare box structure operation. A protecting cover 56 may be detachably se 60 cured against the side of the structure to en close the pulleys 29 and 3| and the driving belt 30. We thus provide a very simple arrangement for fare box structures in which the conductor or collector need only actuate the dumping lever 65 for dumping of deposited coins or tokens, the evaluating and counting mechanisms being then automatically taken care of by the motor. Our invention may be readily applied to fare boxes which have not been motorized. The base structure with the motor and switch mechanism therein can be readily applied to such structure and a sheave substituted on the evaluator and counting mechanism drive shaft for the manual~ ly operable handle, and the switch mechanism for 75 3 2,128,900 the motor starting circuit can be readily applied for operation by the dumping lever. We have shown a practical and efficient em bodiment of the Various features of our inven tion but We do not desire to be limited to the exact construction, arrangement, and operation shown and described as changes and modifica tions may be made Without departing from the scope of the invention. We claim as follows: An electrical control system for motor driven passenger vehicle fare boxes in which deposited coins or tokens are to be evaluated and counted, comprising a driving motor, a starting switch 15 arranged to be opened and closed by the opera tion of the fare box dumping lever, a source of current, a starting circuit adapted when closed by said starting switch to include said source and the driving motor for starting of the motor, a Contact drum having insulating segments and adapted to be driven by said motor after starting 5 thereof, a contact normally in engagement With one of said insulating segments, and an operat ing circuit including said source and said motor and said contact and completed by said drum when said drum after starting of the motor comes 10 into engagement with said contact and to be re opened by engagement of said contact with the next segment.
