This invention relates to liquid dispensing v understood as an. extension of the rod I3 in I
_
,
pumps for gasoline and the like of the type in Fig. 3;
Fig. 4 is a similar view‘ with the motor switch
‘which an indicating register is provided for
displaying the quantity of gasoline dispensed].
5 For accurate service from such a pump it is de
sirable that the register be reset to zero before
each new dispensing operation.
‘
In the form ‘employed with the present inven
. tion the register is ‘reset to zero by a manual
10 operation of the pump attendant independently
of starting the pump.
While the attendant can
usually be relied ‘upon to effect this manual oper- '
' ation of resetting before starting a dispensing
operation, the present improvement‘is designed
‘ringing; and

started for operation without having previously
understood as an extension of the rod l3 in
resetthe register to zero. If- on the other hand,
Fig. 5.
1the reset is, performed before starting the pump
no signal will be given. In other words, the
normal and proper operationof the pump will
prevent the giving of any signal, and the. at
tendant will be Warned only, when by inistake he
has neglected to operate the.reset.
_ _
Furthermore, provision is made so that-if the
attendant starts up the pump without resetting
the register the bell will continue ringing until
either the pump is stopped or the reset is made.
The resetting operation if performed initially will
prevent a subsequent signal, and if performed
after starting the pump, will stop the signal so
' that the dispensing may'then be proceeded with
in proper manner.

Referring more particularly to Figs. 1 and 2,
the pump casing is indicated at. l, and within‘
said casing are suitably arranged the operative
parts of the pump comprising'a combined motor 25'
and pump ‘unit 2 which draws liquid such as
gasoline up through pipe '4 from a source of -
supply-not shown, and‘ drives it through an out
?ow pipe 5, ?uid measuring meter 6, to a de
livery hose 1 in the usual manner.
The motor 30
switch for the motor 2 is contained within the
casing 3. The nozzle guard 8 of the-delivery
hose 1 is adapted for resting on ?xed support, 9
at one side of the pump casing when said hose
is not inuse for dispensing. The operator's 35
handle for the motor switch is indicated at ID as
being ?xed to a handle shaft H and a projection ‘

The pump motor has its shaft extended up
wardly from the casing 2 to provide a rotating
stub portion l5 suitable as a friction driving ele
ment. A mechanically operated signal bell-l6 50
is carried on a swinging arm I‘! pivoted at l8 on
the frame of the pump casing and itwill be
understood that said bell is operated for ring
ing by the rotation of its friction wheel l5’ when
the latter is swung into running contact with the
2

rotating stub shaft |5. The supporting arm H
for the bell I6 is connected by link I9 to one arm
‘of a trip member 26, only a portion of‘ which is
shown in Fig.2, and the more detailed operation
of which will be later described in connection
with the other ?gures of the drawings.
Arranged within the pump casing is a suitable
register indicator 22 Which-is operated through
shaft 23 from the meter 6 whereby in the usual
10 manner said register will indicate the quantity
of gasoline being dispensed through the hose 1.
The form of register 22 herein shown is of the
- well known computer type with dial indicators 24
3|, and the other end 54 thereof abutting the hub
of cam collar 46, the latter being ?xed to the
switch handle shaft ||.
The cam collar 46 has formed in its surface a
recess 41 which when it arrives opposite the end
54 of said rocking beam 33 and assuming said
toggle 38, 42 to be in cocked position, allows said
beam to rock clockwise sui?cient to release the
latch pawl 35 from the arm 21 of the trip member
20 as shown in Fig. 4. 'The switch handle l8 and
its shaft H are limited in movement between on
and off position by means of a stop lug 58'?xed to

The operation of the above described mecha
against the hub of a cam collar 3| which is fas
tened to the end of the aforesaid mentioned re
nism is as follows: Assume that the parts are as
shown in full lines in Fig. 3 wherein the motor

mechanism for the bell is latched in inactive posi 40'

tion. This is the position of the parts after a
tion of the arrow (Fig, 3) and during this revo
lution a cam'32 on.the collar 3| acts against the dispensing operation and after the switch handle
has been turned off and nothing further has been
stud 30_ to latch the trip member 21 into the po
sition shown in Fig. 3. This may be termed the done by the attendant. In other words, the at
holding position of the trip member 21, since it tendant has not yet reset the register to zero and 45
holds the bell |6 out of .ringing position, The the toggle is in its cocked position ready for
trip member'21 is held in this holding position by
'
Under such circumstances the attendant should
rocking beam 33, the latter being pivotally
properly reset. the register before starting the
mounted at 34 upon the bracket 2 I. A latch pawl
spring 31 yieldingly holds the latch pawl 35 in its
position shown in Fig. 3.
A bifurcated segment plate 38 straddles the
rocking beam 33 and is also pivotedat 34 upon,
the bracket 2|, The segment plate 38 carries
‘therein studs or rollers 39, 48 and 4|. Combined
with the plate 38 to form a toggle is a rod 42
pivotally connected at one end at 4|’ with said
- segment plate 38. The other end of said toggle
rod 42 is slidably received within a rocking pivot
studf44 extending from the bracket 2 I. A coiled
spring 45 under compressed tension isinterposed
between said pivot stud 44 and a shoulder on the
rod 42 tending to hold the segment plate 38 in
either one of its two positions.
In the full line
position'shown in Fig. 3, which may be termed
the cooked position of the toggle 38, 42, the roller
40 of plate 38 bears against the rocking beam 33
tending to rock it clockwise. When the plate 38

be termed. the uncooked position, the roller 4|
of said plate 38 bears against the rocking beam

action.
a latch pawl 35 which is pivoted at 36-upon a,
motor for a new dispensing operation. If he fails 150
to do this and turns the switch handle on the
parts will take the position shown in Fig. 4 where
it will be seen that bell actuating mechanism is
making the bell ring. This is due to the fact that
the toggle 38, 42 has been left in its right hand 55
or cooked position tending to rock the beam 33
clockwise. When the recess 41 arrives under the
end 54 of the beam 33, the latter rocks sui?ciently
to remove latch 35 and release the trip member.
20 whereby the latter through its link l9 swings 00'
the bell support H to bring the bell wheel l5’
into running contact with the rotating stub'shaft
-|5 of the motor for ringing the bell.
<
The ringing of the bell warns the attendant
that he has failed to reset. There are .two ways 65
for stopping the ringing'of the bell; ?rst, the
attendant may operate the switch handle-I8 to
turn off the motor and thereby stop the drive to
the bell, and second,-the attendant may operate
the reset handle 25 to reset the register and shift
the toggle to its uncooked position. The revolu
tion of the reset shaft 26 causes the cam 32 to
33 tending to rock it counterclockwise. _ The
throw the toggle 38, 42 to its left hand or un- >
rocking movement of beam 33 is limited by one
end 54' thereof abutting the hub of cam collar
cocked position as shown in Fig. 5.
The cam 32
acting against lug 38 also rocks the trip member
3
2,124,486
I 20 to swing the bell wheel l5’ away from run
ning contact with the stub shaft 50 and at the
same timelatches said trip member 20 in said
holding position as shown in Fig. 5.
'
While it is possible to operate the reset shaft for
resetting the register either before or after they
motor switch is turned on, the-proper way of
operating the apparatus so that the bell signal
will not be given is for the attendant when the
10 switch handle I0 is off as shown in Fig. 3, to
?rst operate the reset. This action throws the
toggle 38, 42 to its uncooked or dotted line posi
tion in Fig. 3. Thereafter when the switch han
dle I0 is turned on the parts will take the position
15 shown in Fig. 5, wherein the bell actuating mech
anism remains latched in holding position with
the bell out of action.
,
The reason for making the pawl 5| yieldingly
retractable from its projected position as shown in
20 Fig. 3 is that when the attendant operates the
reset shaft before turning on the motor switch,
the toggle 38, 40 is thrown to its dotted line
position in Fig. 3. ‘The subsequent turning on
of the motor switch handle willv cause the re
25 tractable pawl 5| to swing into its recess in passing
' the dotted line position of roll 4! and avoid throw
ing the toggleover to ‘its right hand position
during this on movement of the switch handle H).
In this way the bell actuating mechanism trip
30 member 20 will continue to be held in its latched
holding position when the switch handle is turned
on after a previous reset operation.
