a.
This invention relates to a power driven fare
Figure 8 is a section on plane VIII-VIII of
box and register structure of the type in which
the operation of a lever for dumping of deposited
coins sets into operation a. motor for driving the
coin sorting and registering mechanism.
An important object of the invention is to pro
Figure 5.
The fare box shown comprises the inspection
compartment I!) which receives deposited coins or
vide an arrangement in which operation of the
dumping lever will close a switch for the electric
motor circuit, and clock work controlling the
10v opening of the switch after a predetermined pe
riod of operation of the motor.
A further object is to provide an arrangement
in which the motor circuit switch is closed when
the dumping lever is operated and latch mecha
' nism then holds the switch in closed condition, to
tokens from a coin drop (not shown), the sort
ing and register mechanism being within the
housing part II. The dumping plates l2 and I3
are at the bottom of the inspection compartment
and when these plates are swung downwardly
the deposited coins or tokens are discharged 10
through the chute i4 into the hopper l5 where
they are received by the sorting disc i6 secured to
a shaft ll which at its lower end has a worm
wheel l8 meshing with a worm IS on the drive
shaft 29. The drive shaft also carries a gear 2|
gather with clock work which effects unlatching
meshing with a gear 22 which forms part of the
of the switch for reopening thereof after a pre
determined period of operation of the motor.
A further object is to provide an arrangement
in which when the switch is closed by operation
of the dumping lever power is stored in spring
means for driving the clock train and for restor
ing the switch to open condition after a prede
termined period of operation of the motor.
Another object is to provide simple means for
making adjustments for any desired time period
of operation, of the motor.
A still further object of the invention is to
provide switch means in which the movable
operating train for the register mechanism which
totalizes the deposits. Upon turning of the drive
' switch element is quick acting‘ for snap closing
and opening of the switch so as to eliminate
sparking.

mechanism;
Figure 5 is a section on plane V-—V of Figure 4;
Figure 6 is a section on plane VI'—VI of Figure
5;
Figure '7 is an enlarged side elevation of the
latching mechanism; and
shaft the deposited coins or tokens are sorted
and the register mechanism is set for the cor 20'
responding cash value or token entry and the
registers are operated all in a manner as fully dis
closed as, for example, in Johnson Patent
1,344,898 dated June 29, 1920. After sorting and
entry of the coins and tokens they are received 25
in a cup 23 from which they may be readily with
drawn by inward swing of a door 24.
Referring to Figures 3 and 4, the dumping
plates l2 and I3 extend from shafts 25 and 26
from which extend levers 21 and 28, a pin 29 ex
tending from the end of the lever 28 through a
longitudinal slot 30 in the lever 21. The pin ex
tends into a cam slot 3! in the wing 32 extending
upwardly from the dumping lever shaft 33, the
shaft at its outer end carrying a coupling pin 34
receiving the slot 35 in the hub 36 of the dumping
lever 31. A spring 38 tends to hold the dumping
lever in upper position as shown in Figure 1 and
to return it to this position after a downward
swing thereof for dumping of the plates l2 and [3. 40
When the lever is swung down and the wing 32
therewith, the cooperation of the cam slot 3| with
the pin 29 causes downward swing of the arms
21 and 28 and of the plates l2 and i3 for dump
ing of the deposited coins or tokens.
An electric driving motor M for the sorting and
register mechanism is mounted in the base 39 of
the fare box and thru a suitable reduction gear
ing 40 drives a shaft 4! extending thru a side wall
of the base and mounting a pulley 42 which is
connected by a belt 43 with the driving pulley 44
secured to the drive shaft 20. A guard frame 44
is detachably secured against the side of the box
to protect the belt, and this guard has the open
ing 46 through which the drive wheel 44 projects, 55,
2 .

this Wheel being provided with a handle 41 for
manual operation thereof and of the drive shaft
in case the motor should fail. Under such con
ditions the guard frame 45 is removed and the
belt taken off the wheel 44 so that this wheel
may be readily manually rotated for operation of
the sorting and registering mechanism.
Referring to Figures 2 and 4, the end of the
shaft 26 is provided at its end with a crank arm
10 48 for operation of the switch and controlling
clock work when the dumping lever is actuated.
The switch and its controlling mechanism are
mounted on a supporting plate 49 secured in any
suitable manner to the fare box housing. The
15 switch comprises a frame 50 mounted on the
plate 49 and this frame supports a rectangular
block 5! of insulating material, the block having
a recess 52 in which the movable switch member
operates. This switch member comprises a frame
20 53 which journals a contact member in the form
of a roller 51;. A stem 55 extends from the frame
53 and has the slot 56 receiving the pin 51 in the
lower end of a lever 58 pivoted at 5%! on the frame
50. A washer Gil engages the stem 55 below the
25 pin 57 and a spring 6! is interposed between the
washer and the frame 53, the spring holding the
washer at all times against the pin 51.

35 swung and the pin 5? moves to either side of’ the
neutral or dead line the frame 53 will be project
ed by the spring 6| to bring the contact roller 54
into the corresponding lower corner of the re~
cess 52, a spring toggle action being thus pro
vided which gives the switch contact member a
quick or snap action. As best shown in Figures
5 and 8, contact plates 52 and 53 are secured to
opposite sides of the switch block El and project
at their inner ends adjacent the outer lower cor

Describing now the switch latching mechanism,
and the timing mechanism for determining the
duration of switch closure, a connecting bar 5? is
connected with the lever 58 below the lever con
nection with the link 55, the outer end of the con
necting bar being pivoted to the upper end of
a lever 68 which is pivoted intermediate its ends
on a shaft 59 extending from the supporting plate
49. At the lower end of the lever 58 is a pin
15 which pivots a detent or pawl ‘ll having the de
75 tent tooth 12 at its free end for engagement with
the arcuate edge of a sector 13 secured to a hub
14 rotatable on the shaft 59. Also rotatable on
this shaft is a gear 15 to which the hub 14 is
frictionally coupled as by means of friction plates
'16 which are secured to the hub and friotionally
hold the gear between them. The gear 15 is con
nected by a gearing or clock-work train Tl with
escapement mechanism ‘[8 controlled by a pendu
lum wheel 19.
Swing of the lever 58 by operation of the dump 10
ing lever for closure of the switch is resisted by a
spring 80 anchored to the lever 58 and to the
switch frame 50, this spring also furnishing the
power for driving the clock work and for swing
ing the lever 58 back for reopening of the switch.
When the lever 58 is rotated by actuation of the
dumping lever, the lever 68 will be rotated in
clockwise direction, (Figure 5) and the detent
pawl ‘H will be shifted relative to the detent sec
tor 13, a spring 8! tending to hold the pawl tooth
‘l2 against the arcuate edge of the sector. At its
upper end the sector has a notch 82 providing a
detent shoulder 83 which notch and shoulder re~
ceive the detent pawl tooth after the lever 68
has been rotated a distance.
After the tooth en
25
gages in the notch a projection 84 at the pivoted
end of the detent pawl engages the underside of
the sector 13 and the sector is swung upwardly
a distance with the detent pawl in engagement
therewith. This movement of the sector occurs 30
during the latter part of the downward swing of
the dumping lever 31 and during this time the
switch is snapped from its open position to its
circuit closing position. Then upon release of
the dumping lever, it is returned by its spring 38 35
to its normal position and the spring 80 then be
comes effective for moving the switch lever 58
back toward its normal or circuit opening posi
tion. Such movement causes counter-clockwise
rotation of the lever 68, and the latch pawl ‘H 40
which is in engagement with the shoulder 83 of
the sector will carry the sector along. The dura
tion of latching engagement of the pawl with the
sector is determined by a cam member 85 in the
form of a bell crank structure frictionally secured 45
on the shaft 59 in front of the lever 68. This
cam member presents a cam edge
to a roller
8'! at the base of the pawl tooth 72. Figure '7
shows the position of the latching element after
the dumping lever has been actuated and the 50
spring 85 has been released for operation. As
the lever 68 is then rotated in counter-clockwise
direction and the sector '53 is moved with the
pawl, the roller 23‘! engages along the cam surface
85 and the pawl is gradually swung outwardly 55
until its tooth ‘I2 is ?nally withdrawn from the
latch shoulder 83. Movement of the latch sector
‘it and the latch pawl mechanism is resisted by
the gearing train Tl to which the gear 15 is fric
tionally coupled to the sector hub ‘M and as the 60
sector is carried with the latch pawl by the power
of the spring 80 the clock train is operated to re
tard and time the movement.
As soon as the
pawl tooth is cammed from the sector the re
tarding in?uence of the clock train is removed
and the spring 80 will then rapidly restore the
lever 58 and the latching mechanism to normal
position and the switch will be snapped back to
circuit opening position as shown in Figure 5.
the lever 58 resting normally against a stop 88
on the plate 49.
By means of its upstanding arm 85’ the fric
tionally supported cam member 35 may be ad~
justed for setting of its cam surface 86 upwardly
or downwardly so as to determine the time period 75
2,118,938
of retardation by the clock work and thereby the
time interval of circuit closure by the switch and
operation of the motor.
The clock train is self-locking so that, when
the dumping lever is actuated for closure of the
switch and movement of the pawl ‘H into latch
ing engagement with the sector, the sector will
be swung independently of the clock train by
virtue of its frictional connection with the gear
10 15, and then when the dumping lever is released,
the return movement of the latch sector friction
ally rotates the gear 15 and the clock train.
We thus provide simple arrangement in a fare
box and register structure in which, by the actu
15 ation of the dumping lever, the driving motor
circuit switch is quickly closed with snap action
and is then held in closed position for a prede~
termined length of time when it is automatically
snapped back to circuit opening position for stop
20 ping of the motor, the time period of switch clo
sure being readily adjustable.
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
25 construction, arrangement and operation shown
and described as changes and modi?cations may
be readily made without departing from the spirit
of the invention.
