17 Claims. (Cl. 221—95)
The present invention is directed to operating
and control mechanisms for dispensing pumps
and the like, and as hereinafter described, is par
ticularly applicable to pumps of the type used in
6 gasoline filling stations.
‘
Dispensing pumps of this character usually in
clude a motor operated pump, a meter for meas
uring the amount of liquid dispensed, and an iii
dicator actuated by the meter. The indicator is
10 ordinarily designed to be reset prior to each dis
pensing operation and automatically operating
resetting means are sometimes used in order to
insure the resetting of the indicator to zero and
proper indication of the amount of liquid dis»
15 pensed in each separate transaction. In some
constructions also the indicator or registering den
vice used is complicated and imposes a load upon
the meter due to the power required to actuate
an accurate measure of the amount of liquid
dispensed.
For a better understanding of the present in
vention, reference may be had to the accompany
ing drawing, in which:
Figure 1 is a view in elevation, partly broken

The automatic operation of the apparatus ef
fectually prevents fraudulent or inadvertently
improper operation of the device, since the se
quence of operations cannot be altered by the op—
orator. Thus, the invention provides a simple
coustructionwhich operates in a positive manner
to assure both the customer and the operator that

A construction similar‘ in certain respects to
that described above, and including a motor
claimed in the copending application of William
L. Marden, Serial Number 51,980, ?ied November
29, 1935..
The construction described permits operation
driven resetting means for the indicator which
is adapted to be disengaged from the indicator
upon continued operation of the motor after the
indicator has been reset, is described and claimed
in my copending application, Serial Number
10
83,030, filed June 2, 1936.
In order to control the starting, stopping and
of the indicator by the motor in one direction
only, due to the driving connection through
ratchet member l6. However, the speed of op
eration of the indicator is controlled by the meter,
although the motor may be driven at higher
speed due to the slip connection provided by the
spring ?ngers I5 engaging the face of the ratchet
member Hi. The spur teeth of the gear l8 engage
reversal of the motor i8, in an automatic man
the gear 28 to drive the same. The latter is se
cured to a shaft 38 on the upper end of which
ner, the apparatus utilizes the hose support 14,
pivotally mounted in lugs ‘I8 on the frame A as
a convenient master control. It will be under
stood that other manually actuated means may
be used as a control means for the purpose of my
invention, but I have illustrated the mechanism
as including an enlarged inner end 18 on the
15 is secured a gear 32 meshing with crown gear 84
provided with peripheral teeth for driving the
gear 38 and shaft 88 to which the indicator
pointer 48 is secured. Gear 38 is frictionally
clutched to shaft 38 in order that the indicator
20 hand 48 may be reset to zero position.

lar shaped cam track 88 is provided. Cam track
_
The connections between the meter 6 and the
gear 36 are so proportioned that the gear 38 and
88 receives a roller 82 mounted upon a switch
actuating arm 84 which through shaft 88 moves
the switch blades contained in switch block 88 to
any one of three positions in accordance with a 25
predetermined sequence of movements of switch
arm 84. The sequence of the movements is de
termined by the position of roller 82 in the cam
track 88 which is in turn determined by the
pointer 48 are caused to make one complete ro
tation for each gallon, or other unit of liquid,
25 passing through the meter in the dispensing op-.
eration. Suitable connections (not shown) may
also be provided between the shaft 38, and a
shaft 42 carrying a second pointer 44 to-cause
the pointer 44 to be advanced one interval upon
30 every complete rotation of the pointer 48.‘ A
suitable clutch and pickup mechanism may bev
provided between the mechanisms for rotating the
pointers so that they may be returned to zero
position by rotation together. The pointer 48

When the hose is on the support, its inner end
18 is raised and the roller 82 rests in the lower
end of the cam track 88 at position F. In this
- position the switch is open. and the pump motor
2 and reversible motor l8 are inoperative. When 35

During the dispensing operation, these parts
will operate as'described, and the indicator will
40 move in one direction.
However, the indicator
should be reset prior to a succeeding dispensing
operation, in order that each. transaction may be
indicated separately. This is accomplished by
rotation of the motor in the-opposite direction
45 from that in which it rotates indriving the in

track 88 by latch .98 disposed in the cam track.

88 for engagement with the teeth of the ratchet
driven in the opposite direction.

-
As gear 48 is rotated it drives idler gears 52
andv 54, the latter meshing with a barrel gear 56,
?xed to shaft 58. Shaft 58 is axially shiftable in
a bearing 68 on frame A and in a sleeve 82 ?xed
to indicator shaft 38. Shaft 58 carries at its left
60 hand end as viewed in Fig. 1, a pin 84 slldable
in a spiral slot 88 in sleeve 82 upon relative
rotation between shaft 58 and sleeve 82. The
pin 84 is normally retained at the left hand and
of slot 64 by a spring 88, and sleeve 82 and shaft
58 are therefore rotated together when the indi
cator is being returned to ‘zero, by proper direc
tional rotationof motor l8. In order to stop the
indicator hands 48 and 44 at zero position, shaft
70 88 carries a ?xed'single tooth ratchet 18 which is
engageable with a pawl 12 mounted on the frame
A when the hands reach zero position thus pre-.
venting further rotation of shaft 38 and sleeve
82. As the motor l8 continues to drive shaft 58,
I the pin 64 will travel to the right along spiral '
gagement with switch arm 84. Continued dis
placement of disc 98, moves roller 82 and switch 55
arm 84 to the right into position E at the upper
end of the right hand branch of cam track 88.
In position E, the switch 88 reverses the direction
of rotation of motor l8 and energizes pump motor
2, so that a dispensing operation can take place. 60
The motor I 8 will then rotate'in the proper direc
tion to drive the indicator hand in accordance
with the ?ow of liquid through meter 8, as pre
viously described. In order to aid the switch arm
84 in its movement from position ‘D to position 65
E, a spring-actuated toggle I88 is plvotally
mounted on the frame A and engages a bifurcated
end i 82 on switch arm 84, so that upon movement
of ‘arm 84 past dead center from position D, toggle 70
I88 will snap it to position E. The switch arm
will then be retained in position E until moved
therefrom by upward movement of the inner end
of the hose support.

turn of the hose to the support ‘I4 raises end ‘I8
of the support and roller 82 moves along the right
hand branch of cam track 80, to position F.
Latch 80 is depressed as roller 82 passes over‘
the same, and thereafter snaps back to its pro_
jected position preventing movement of the roller
from the position F to the position E when the
inner end of the hose support is again depressed.
The mechanism is thus restored to?its original
“01!” position.

.
In order to control the sequence of operations
described from switch 88 the circuit of Fig. 4 may
be used. Referring to Fig. 4, the switch 88 is pro
vided with twopivoted switch blades I04 and I06
15 and three contacts ‘I08, H0 and “2, the contacts
and blades being so spaced that only the center
contact H0 and one of the outer contacts I08 or
II2 can be engaged simultaneously by blades I06
and I04. In position D of the switch operating
20 arm 84 previously described, the blades I04 and
I06 of the switch engage contacts H0 and I08
respectively as shown in full lines in the drawing
in which motor I0 is rotated in one direction.
Position E of the operating arm previously de
25 scribed corresponds to the dotted line positions
of Fig. 4, with blades I06 and I04 engaging con
tacts I I0 and I I2, respectively, wherein the motor
I0 is rotated in the opposite direction and pump
motor 2’is actuated. In position F, the blades
30 I04 and I06 are disposed between and out of
engagement with contacts‘ I08, H0 and H2, and
both motors 2 and I0 are inactive.
One line II4 of a source of electrical energy
is connected to one terminal of pump motor 2,
35 and through resistance II6 to contact H0.
The
opposite line H5 is connected to contacts I08
and H2. The opposite terminal of motor 2 is
connected to switch blade I04 and to one ter
minal of reversing motor I0. The opposite ter
40 minal of motor I0 is connected to switch blade
I06.
'
The power line II4 may have a master
and upon-removal of the hose from the support
‘I4, end ‘I8 of the support may be raised so that
switch roller 82 is directed by latch 90 into the -'
left-hand branch of cam track 80 to position D,
starting motor 6 in the proper direction to reset
hands 40 and 44 to zero. Rotation of the motor
is transmitted through ratchet 46 and pawl 50 to
gears 48, 50 and 52 to barrel gear 56 and shaft 58.
Pin 64 being at the left-hand end of the slot in
sleeve 82 rotates the sleeve and‘ shaft 38 to move 10
hands’ 40 and 44, returning them toward zero.
At the same time pawl 20 and ratchet I8 dis
engage permitting iree rotation of shaft I2 and
hub I4 with respect to worm 22 and worm gear I8.
. When pawl ‘I2 on the dial of indicator B is 15
engaged by the tooth of ratchet 10 on shaft 38
at zero position of the indicator B, the sleeve
62 is locked against further rotation, but the
motor I0 continues to rotate shaft 58 causing
pin 64 to travel along spiral slot 66 against the 20
action of spring 68 displacing the shaft 58 and
disk 98 to the right as viewed in Fig. 1.“ As the
disk 98 moves it contacts with-the end of switch
operating arm 84 displacing it to the right against
the biasing eiiect of spring pressed pin I00, until
arm 84'passes dead center. Pin I00 then snaps
switch arm 84 and roller 82 to position E, thereby
reversing the direction of rotation of motor I0
terminating the resetting operation and driving
gear I8 under control of meter 4.
At the same 30
time the circuit for energizing the pump motor
2 is completed, whereupon the pump 4 is actu
ated and a dispensing operation may take place.
As liquid is pumped through meter 6, the gear
train 24 is driven, rotating worm 22. Reversal 35
of motor 6 disengages pawl 50 from ratchet 46
and engages pawl 20 with ratchet I6. The indi
cator hand is thus free to be driven by motor
I0 while spring 68 returns pin 64 to its initial
position at the end of spiral slot 66 in sleeve 62 40
