If one wishes to write a text with the typewriter, for
example, the address on the calculation form, or the
account number as well as the date, the typewriter is
disconnected from the calculator by means of a switch
1 (FIG. 5B). When the heading of the invoice has been
written, namely the part of the information not requir
ing calculation, the calculator is again connected to the
typewriter by the action of the switch 1.
The typewriter is tabulated to column I of the invoice
form by means not shown, where the value 15.50 is to‘
be entered in column I. Now, the numbers are typed dur

initiates the operation of a well-known type of single

mechanism is the same as that disclosed in the previously
mentioned Patent No. 2,271,240 Where are shown ten
multiplier keys 2001 representative of the digital multiplier
values “0” and “1” to “9.” Depression of each key, either
manually, as disclosed in the patent, or by a respective
solenoid 70k~7tla as disclosed herein, initiates ordinal
multiplication ?rst by the lowest ordinal multiplier digit
and each such ordinal multiplication operation is fol
lowed by an automatic shift of the product register in an
ascending direction relative to the ordinal actuators. The
switch 72 (FIG. 2) is closed soon after the energization of
intermediate tab key is simultaneously depressed with
the rightward tabulation initiating key, then rightward
tabulation of the carriage is terminated when the carriage
reaches a position corresponding to the index of the in
termediate tab key; on the other hand, if an intermediate
tab key and the leftward tabulate initiating key are simul
taneously depressed, the intermediate tab key does not
terminate tabulation, and the carriage is shifted to its
leftmost position. In the present case, all of the solenoids
for the tabulator keys bear the reference numerals 9 and 9a
except for the solenoid 81, the energization of which de
presses the leftward tabulate initiating key.

solenoid 70a to ‘70k. This current interruption follows
if the multiplier is a value 1 to 9, Whereas the current
interruption at the processing of the multiplier value of
“0” occurs through the switch 75 (FIG. 3), which switch
is closed by a cam 76 of the step switch 67. The product
register carriage 250 (FIG. 3) of the calculating machine
has a rack and pinion drive connection 251-252 for driv
ing a shaft 253 each time the product register is shifted.
Shaft 253 has appropriate drive connection with a shaft
254' upon which is ?xed an eccentric cam 255 (for the
step switch 67) and a step cam 76. Cam 255 closes
and opens switches for successively enabling the ordinal
multiplying circuits. Cam 76 closes switch 67 during
each shifting operation. After the calculator has com
pleted the ?rst multiplication, the carriage automatically
plying by the values 1 to 9, and the contact 86 (FIG. 5A)
is provided for the value “0.” According to the numeral
value, the circuit is closed at the delay relays 87, 88
through one of these contacts 85, 86, or through both.
By the cooperation of these relays, the contacts W and
St? are opened and the return shift of the calculator’s
carriage and the interruption of the current for the step
switch 67 are delayed until the calculation operation is
?nished and the previously mentioned switch pinning lever
71 (FIG. 2) has returned to its normal position. The con
tact 86 (FIGS. 3 and 5A) is closed by the cam 76, only
for a short time, and, more speci?cally, during the shift
from order to order. After the calculating operation is
stopped by the proceeding described above, and the prod~
uct appears on the result device 559 (FIG. 1A) of the
shifted one order to the next higher ordinal position, at
calculator, the product register carriage is returned to its
which operation the cam 255 is simultaneously rotated
one step. Because of the shifting motion of the cam 255,
the contact 68 (FIG. 5A) is opened and the contact 77 is
closed for the next decade. Now, the multiplying opera
tion is repeated in accordance with the value of the next
ordinal multiplier value and this process is repeated in
each order until the last order is reached. In this posi
tion (last multiplying order) a contact 78 is closed, by
initial leftmost shifted position.

‘
In the above description, the ?rst value which was
typed (in C01. I of the invoice) was entered into the
storage device A (FIG. 113) as a multiplier value by virtue
of the fact that a lug on the platen carriage closed a
switch to to energize the solenoid 11; however, if this
same lug had closed the switch 10a in the circuit of the
solenoid 111a, then the ?rst factor would have been entered
into the selection bars 49 as a multiplicand factor. Thus,
it will be clear that the invoice may be altered to suit
the customer and that the sequence of entry of the mul
tiplier and multiplicand factors is but a matter of choice.
Descriptive matter may be written in the third column
so that the armature (not shown) causes the initiating of

the solenoid 91, which contact is closed by the action of
the relay 123 if the latter becomes de~energized by the
opening of the contact 124. The contact 124- is closed
during the carriage shifting from the end position (of
the calculator) to the regulated decade by the cam 76
(FIG. 3) and opens the contact 1122 by energization of
the relay 123. Only when the carriage has stopped in
the selected decade, the contacts 124 remain open, the
relay 123 falls back, and the contacts 12-2 close the cir~
cuit for the solenoid M. ‘In this manner energization of
solenoid 91 and the initiation of a product value sensing
operation is delayed in case the product register is being
shifted at the time the contacts 99 (FIG. 5B) are closed.
Under most conditions, shifting will have been completed
by the time the typewriter carriage is tabulated to column
IV of the invoice from where the product is to be typed
out; however, under certain conditions the product regis
ter will be shifting at such time.
It will be recalled that
at the end of multiplication, the solenoid 83. (FIG. 5B)
is energized and the product register is return shifted to
its initial leftmost position. This is the position in which
the product register normally stands when read-out oc
curs. As noted hereinafter, the product is typed out in
terms of dollars and cents and therefore only two frac
tional digits are required to be typed. Means described
hereinafter, are provided to print a decimal point between
the second and third rightmost digits of the product; there
fore, if the sum of the fractional digits in the product
is equal to tWo then when the product register is shifted
to its extreme leftmost position, the decimal point in the
product register and the decimal point in the product
read-out mechanism will be properly aligned. Assume,
however, that the sum of the fractional digits in the mul
gle cycle clutch for driving the product register numeral
wheels in a reverse direction.
The Wheels 89 (FIG. 1A)
of the product register are turned to the initial position,
or naught, by the clearance operation of the calculator,
and the racks ‘113, which are engaged with the numeral
wheel gear 273, are moved to the value previously stand
ing in the product register. The solenoid 133 (FIG. 2)
is energized simultaneously with the solenoid 129.
Through the cooperation of the solenoid 133, the lever
13s is rocked by means of the bolt 134, and the shaft 136
rocks a control lever 137, which engages a single cycle
clutch and closes the contacts 133. The contact 138
switches on the motor current which motor circuit is
closed by the contacts 139 for the time duration of a ro
tation of the cam shaft 140 by the clutch, whereas the
circuit is opened for the solenoids 129 and 133 by the con
tacts 13% at the start of the rotation motion. Through
60 the rotation of the cam shaft 149, the contacts 141 of
the commutator 360 are closed one after another.
Cam
1159 (FIG. 2) on shaft 140 closes switch 147 (FIG. 5B),
thus completing the preparation of the product type-out
circuit.
The circuit for the ?rst order is closed by the closing
of the ?rst contacts 14-1 by means of the cam 142 (FIG.
2) and of the pin 143. Thus, one of solenoids 144 (FIG.
5A), corresponding to the number key of the typewriter,
is energized, to wit, that solenoid which corresponds to
the strip 145 on which the contact brush 146 ?nds itself.
The energized solenoid 144- sets in motion the key lever
corresponding to it, by which the respective number is
typed out in the known manner. The process, just now
described for typing the ?rst number, is the same as for
typing of the other numbers by the successive closing

in the same manner, as already described. By the opera

are ‘closed and, therefore the electric circuit for the sole

by an automatic operation, in the column V by the tab
