GENERAL DESCRIPTION
Described in general terms, the essential ele
ments of this divisional application are embodied
in a machine known as the “key set, motor or
70 crank operated type.”
The machine used for illustrative purposes
contains seven banks of amount keys, a bank of
clerks’ keys, and a bank of transaction keys. A
motor bar is also provided to release the machine
75 for operation.
remotely located therefrom in the printing mech
anism. When the control lever is moved into the 45
bottom or grand total position, it controls mech
anism whereby the totalizers may be successively
brought into a position to be reset to Zero upon
continued operation of the machine.
Suitable interlocks are provided to insure 50
against any misoperation of the machine. Locks
are also provided for locking all of the moving
parts in the totalizer reel against movement, so
that they will remain in place when the reel is

tions. The gears of the transmission line are
also locked against operation when said line is
out oi normal position, so that the gears will
properly mesh with their related gears in the
machine proper, when the transmission line is 60
rotated during total taking and resetting opera
restored. An interlocking mechanism is also
provided between the main operating mecha
nism and the reel, so that the machine cannot
be operated after the control lever has been
moved to sub-total or grand total position unless 65
the reel is move-d into a total printing position.
An interlock is also provided to prevent operation
of the machine when the reel has been arrested
between total printing operations.

clerks’, and transaction keys have been operated
in item entering operations, shaft |23 will have
been released for operation, as fully described
cabinet for receiving the key banks and other
15 control mechanisms, as shown in Fig. 1.
Operating mechanism`
Power is imparted to the various mechanisms
by a main driving shaft 21| (Figs. 2 and 3) driven
20 either by an electric motor 2| or a hand operated
crank 22. The shaft 23 is given one complete
rotation at each operation of the machine. As
shown in Fig. 2, the usual reduction gearing
designated generally by the character 23 is pro
25 vided between the electric motor and the short
shaft 24, which extends through an opening in
the frame ||f` and carries a pinion 25 which
meshes with the gear 26 attached to a flanged
disc 21 of a clutch 26. Cooperating with the
30 clutch 28 is a member 23 fixed to the end of
the shaft 2U to cooperate with the flanged por
tion of the disc 21 to cause the clutch members
28 and 29 to drive the shaft 23 when the motor
is operated.
10
in the parent case.
Mounted on shaft |23 in close juxtaposition to
the inner side of side frame I2 is an arm |24, as
shown more clearly in Figs. '7 and 9. The upper
portion of arm |24 is provided with an open slot
|25 which receives a pin |26 provided on link |21.
Link |21 is pivotally supported by arms |28 and
|23 pivoted respectively on studs |30 and |3|
provided in side frame I2. Fixed to motor re
lease bar 43 is a plate 43' slidably mounted on
studs |32 as shown in Fig. '7. A roller |33 pro
vided at the lower end of plate 43’ normally en
gages a foot |34 provided at the lower end of
link |21. Thus, it is seen that when the motor
bar 43 is depressed, .roller |33 will be moved out
of engagement with foot |34 and spring |35 will
move link |21 downwardly if shaft |23 has been
released. A depending arm |36 is fixed to a shaft
20
25
y
30
|31, which shaft is also journalled in side plates
35l The control for the motor switch 23’ is gen
` erally shown in Figs. 2 and 7. The clutch and
switch control mechanism associated with the
motor 2| are of a well known type such as that
disclosed in the United States patent to Charles
40 F. Kettering and William A. Chryst, No. 1,144,418
issue-d June 29, 1915, and therefore this mecha~
nism will not be described any further.
To operate the motor it is only necessary to
rock an arm 38 (Figs. 3 and 7) out of engagement
with a plate 32' and notches (not shown) in the
` locking plates of the clutch and switch control
mechanism.
The motor 2| is mounted on a support 32 at
tached to the frame I I by suitable screws or bolts.
Referring to Fig. 2, it can be seen that the
shaft 23 has secured thereon a pinion. 33 which
meshes with a large idler gear 34, which in turn
meshes with a .gear 35 driven by a hand crank
22. By this mechanism, means is provided for
driving the shaft 2l] manually. A suitable clutch
mechanism is provided between. the crank 22 and
the pinion 35 which permits movement of the
gears 33, 34, and 35 without moving the crank 22
when the machine is operated by the electric
60 motor 2|.
Suitable means is also provided to
permit removal of the crank 22. A form of such
mechanism is shown and described in the United
States patent to Frederick L. Fuller, No. 1,394,256,
issued October 18, 1921.
Keyboard
The keyboard (Fig. l) is composed of seven
banks of amount keys 40, one bank of clerks’
keys 4|, and one bank of transaction keys 42.
A motor bar 43 is also provided for effecting re
lease of the machine.
These banks of keys 4|), 4|, and 42 control the
entry of amounts in totalizers mounted in a
totalizer reel during item entering operations and
also cooperate with a series of interlocks which
I2 and |4. A hook member |38 pivoted on shaft
13 normally engages the lower end of arm |36 as
shown in Fig. 9. Also ñxed to shaft |31 is a
substantially horizontal arm |39 having pivoted
to the outer end thereof, at |46, a spring urged
link |4|. The lower end of link | 4| is provided (0
with a slot |42 which receives a pin |43 attached
to the forward end of an arm |44. Arm |44 is
fixed to shaft |45 which has also ñxed thereto
the arm 39 which normally engages the locking
plates associated with the clutch and motor
switch control mechanism as shown in Fig. 7.
Thus, it is seen that when the proper keys have
been depressed and the motor bar 43 is den
pressed, roller |33 will be moved out of the
path of projection |34 and spring |35 will move
link |21 downwardly to the position shown in 50
Fig. 8. By this action, shaft |23 will be rocked
in a counter-clockwise direction, thereby carry
ing arm |24 with it. Pin |26 on link |21 will
then engage cam face |46 (Fig. 7) provided
at the upper side of hook |38, thereby disengag 55
ing hook |38 from arm |36. Spring |41 at»
tached to link 14| will then move the latter up
wardly, thus rocking shaft |45 in a clockwise di
rection as viewed in Fig. 7, to remove arm 39
from locking engagement with plate 32', with 60
the result that the switch control mechanism
will close the electric motor switch and cause
the motor to drive shaft 20 through the con
nections previously mentioned.
Referring to Figs. 7 and 8, it will be seen that
65
link |21 carries a pin |51 near the upper end
thereof. This pin lies in the path of movement
of arm |36 but is spaced therefrom toî permit
downward movement of link |21 to cam hook 70
|38 out of engagement with arm, |36. From the
foregoing description, it is seen that immediately,7
upon disengagement of hook |33 from arm |35,
spring |41 will rock shaft |31 in a counter
clockwise direction, causing arm |36 to engage
4
2,127,684
pin |51 and thereby move link |21 upwardly.
Since pin |26 of link |21 projects into slot |25
of arm |24, shaft |23 will be rocked in a clock
wise direction, when link |21 is actuated’by arm
|36 in the manner just described. When this
occurs it is obvious that abutment |34 will be
moved clear of the path of movement of roller
|33 and spring |50 will restore the motor bar 43
to normal position, thereby bringing roller |33
10 into engagement with abutment |34 of link |21
as is shown in Fig. 7.
Referring to Fig. 7, it will be seen that a pin
ion |59 is fixed to driving shaft 20. Pinion |59
meshes with an idler gear |60, which in turn
15 meshes with a gear |6| fixed to an intermittent
gear |62. Intermittent gear |62 carries a pin
|63 which normally occupies a position a short
dista-nce below the lower arm |64 of a two-arm
lever |65 (Fig. 7), which is loosely pivoted on
20 shaft 20. The upper arm |66 of lever |65 is
provided with an open slot |61 at its forward end
which receives a pin |68 extending laterally from
link |4|. Intermittent gear |62 is driven in the
direction of the arrow, shown in Fig. 7, and
25 from the arrangement of the parts just described
it is clear that near the end of a complete rota
tion of gear |62, pin |63 will engage arm |64,
thereby rocking the same downwardly. By this
action, arm |65 will move link |4| downwardly
30 against the tension of spring |41. These parts
are so constructed that by the engagement of
pin |63 with arm |64 in this manner, shaft |31
will be rocked in a clockwise direction substan
tially 2()0 beyond its normal position. When the
parts have been thus moved, pin |63 will have
moved out of engagement with arm |64 and
spring |41 will restore the parts to normal po
sition.
When link |21 was elevated by arm |36
pitman |8| is bifurcated to straddle a collar |84
provided on shaft |65. A cam plate |86 is fixed
to shaft |65 and is adjusted by control lever |80
in a manner which will hereinafter be described.
Plate |66 (Fig. 31) is formed with a plurality of
radial slots l81a, |3119, and |610, provided at the
lower side of arcuate portion |88 thereof. Two
radial slots |89a and |6913 are provided along the
outer periphery of arcuate portion |88. Pitman
|8| is provided with a stud |90 which is adapted 10
to move into any one of slots |81 depending upon
the position of the control lever. The purpose
for which slots Hilo, |8111, and |B1c are provided
will be described hereinafter. A second stud |9|
is formed on the same side of pitman |8| as is 15
projection |90 and is spaced therefrom a distance
equal to substantially the width of arcuate portion
|38. Cam faces |92 are provided at each side of
portion |86 and are adapted to engage studs |90
and |9| to move pitman |8| downwardly when 20
the control lever is moved to certain positions of
adjustments. When the control lever is in the
Lock register or the Sub-total position, stud |9|
will register with slot |80@ and when it is in Grand
total position, stud |0| will register with the slot
limb. It is seen from the construction of the
parts just described that when the control lever is
moved to the Lock register, Subetotal or Grand
total position, pitman |8| is moved downwardly
by the yengagement of stud |00 with the inner 80
cam face |92. This movement of pitman |8|
rocks shaft |23 in a clockwise direction, thereby
moving arm |24, Figs. 7, 3, and 9, in a clockwise
direction so that the left«hand Side thereof will
assume a position beneath pin |26 provided on
link |21. Upon depression of motor bar 43 (Fig.
7), link |21 will be moved to the left in the man
ner described heretofore, causing pin |26 carried
and held in its upper position by engagement
of its lower end with roller |33, spring |69 rocked
`hook |38 in a counter-clockwise direction, so
that the end of arm |36` reengaged the end of
the hook when link |4| was drawn downwardly
and released, thereby locking link |4| in normal
position as shown in Fig. 7. A slot |42 provided
at the lower end of link |4| permits a small
