for clarity, showing particularly the consecutive
records for auditing purposes of various kinds of
transactions, such as “cash”, “paid ou ”, and
-' “no sale”, and is a division of applicant’s appli
cation Serial No. 563,757, ?led September 19,
1931, which issued January 4, 1938 as Patent No.
2,104,588.
The present invention embodies improvements
the machine disclosed by applicant’s appli
cation Serial No. 13,470 ?led March 6, 1925, and
10 ‘upon
issued as Patent No. 1,873,760 on August 23, 1932.
Like the machine of the prior application, the
present machine is of the key operated type,
‘wherein the operation of selected amount keys
simultaneously advances the totalizer and one
or more special counters referred to above.
The
prior application also discloses an arrangement
I
for printing a running or subtotal, and for print
20'5ing a grand total, by a store manager and an
auditor, respectively.
An object of this invention is to provide a novel
resetting means for the transaction counters as
sociatecl with the check printer and detail strip
printer respectively. Inasmuch as these counters
2
have corresponding numbers, it is desirable that
they be reset by the same operation. A difficulty
arises, however, in resetting two counters in
di?erent parts of the machine, because of the
friction necessary to be overcome by the reset
3O
lever. If the two counters were reset at exactly
the same time, the friction would be greatest near
the end of the resetting stroke when'all of the
totalizer elements are being moved from “9” to
.“0".
As a result, the manager might move the
35
reset lever until the counter elements have all
reached the “9” position, and, on ?nding opposi
tion to the further movement of the lever, fail to
complete the resetting operation in the belief that
40 the lever has moved a full stroke.
To prevent
this, an arrangement is provided for distributing
the force necessary to reset the two counters.
Accordingly, the counters are so connected with
each other and with the reset lever that upon the
45 upstroke of the lever, the check printer counter is
restored to zero, while on the downstroke, the
counter for the detail strip printer is restored.
With this and incidental objects in view, the
invention consists in certain novel features of
50. construction and combinations of parts, the es
sential elements of which are set forth in the ap
pended claims and a preferred form or embodi
ment of which will now be described with refer
ence to the drawings which accompany and form

General description
This divisional application relates particularly
to the consecutive counter associated with the
check printer and the consecutive counter asso~
ciated with the detail printer. The mechanism
particularly involved is that associated with the
resetting mechanism for these two consecutive
counters, which is arranged so that both may be
reset by the operation of a single lever. These
mechanisms are arranged to make the resetting
particularly easy, by resetting one of the counters
on the forward stroke of the resetting lever and
the other counter on the return stroke of that
,
lever.
Check printer-Consecutive counter
It is considered desirable to consecutively num—
bar the checks issued from the machine and to
carry out this result the illustrative machine is 40'
provided with a series of consecutive number
printing wheels to which a unit is added during
each operation of the machine.
The consecutive numbering counter is of the
multiple pawl, deep notch transfer type, well 45
known in the artand described in many patents,
one of which is the patent to Carney, No. 876,295,
dated January '7, 1908. The consecutive number
ing wheels 60 (Fig. 2) are formed with printing
characters and are loosely mounted upon the
shaft 53.
The consecutive counter wheels are actuated in
a manner well known in the art, by the ball 64
loosely mounted upon the shaft 53. The ball 64
has attached thereto a pin 65 cooperating with an 55
arm 65 which is loosely mounted upon the shaft
32. The arm 66 at its rearward end is bifurcated
to cooperate with an eccentrically mounted disk
61 securely attached to the driving shaft 3|.
From the above it will be readily. understood‘ that

for each operation of the machine, whether for a
“cash”, “paid out”, or “no sale” transaction, the
driving shaft 3I and cam disk 61 will make a com

bar 435. The forward end of the horizontal bar of
the bell crank is similarly slotted to receive a pin
plete revolution, thereby rocking arm 66 and bail
on an arm 45I secured to a shaft 452 (Fig. 1).

I8I, pivoted to rock about the shaft I24, carries
a pawl I82 (Fig. 3) for advancing the units wheel
of the counter each time that the bail is rocked
back and forth. Loosely mounted upon the shaft
32 is a bail I83 (Figs. 2 and 3) having at its left
end two parallel rearwardly extending arms I84
which engage with the top and bottom respec
tively of a disk I85 mounted eccentrically upon
the main driving shaft 3| and secured thereto. A
link I86 connects the bail I83 with the bail I8i.
During each operation of the machine, the main
driving shaft 3| and the eccentric disk I35 make
a complete rotation, thereby rocking the bail I83
?rst upwardly and then downwardly. By means
of the link I86, the bail IBI and pawl I82 are
rocked rearwardly and then forwardly to cause
the pawl to engage a ratchet attached to the units
wheel, whereby the consecutive counter is ad
vanced one step.
Resetting the counters for the check printer and
detail strip printer
The resetting mechanisms for the consecutive
35 counters in the check printer and detail strip
printer respectively are shown best in Fig. 5. It
will be remembered that the consecutive counter
wheels I80 in the detail strip printer are rotatably
mounted on a shaft I24, which shaft is adapted
40 to be rotated by a segment gear N10 for reset
ting the consecutive counters. Similarly, the con
secutive counter wheels Bil in the check printer
are mounted on a shaft 53 which is adapted to be
rotated in a clockwise direction (as viewed in
4.5
Fig. 5) in order to restore the counter elements
to zero.
Secured to the shaft 53 is a spur gear
440 (Fig. 5) which meshes with a segment 44!
pivoted to a side frame I2 at the right end of
the machine. The resetting segments H10 and
50 441 are so connected by a series of levers and
links that the two segments move at the same
time, but in opposite directions. Normally, rota
tion of the segments is prevented by a locking
plate 443 pivoted near its center to the end frame
55 I2, the upper end of the locking plate engaging
the lower end of the segment 448, thereby preventing downward movement of the latter. Up
ward movement of the segment MI is limited by
a pin 445 secured to the frame I2. The locking
60 lever 443 is also provided with an arm 445 hav~
ing detents 441 for engaging the pinions on the
date setting wheels 30, whereby the date wheels
are normally locked against rotation.
It is desirable that the resetting of the consecu~
65 tive counters in both the detail strip printer and
check printer be under the control of either the
auditor or the store manager who is entrusted
with a key for operating a lock M8 or M5. In
the illustrative machine, an arrangement is pro
70 vided whereby, when either the lock M5 or the
lock 416 is turned, the aforesaid resetting mecha
nisms are unlocked for rotation. Referring to
Fig. 1, a bell crank 449 is pivoted upon a stud
450 supported by the intermediate frame it. The
upper end of the vertical arm 449 of the bell crank
453, the free end of which is provided with a pin
454 riding in a symmetrical cam slot 455 pro 10
vided in the locking lever 443. When the store
manager inserts his key into the lock M5 and
rotates the latter counter-clockwise, the shaft
MI is shifted to the right and through a pivoted
link connection (not shown) shifts the shaft 429 15
to the left. The latter rocks the bell crank 432
counter-clockwise, thereby moving the slidable

is connected to the slidable bar 435 and the arm
45I on the shaft 452, causes this shaft to rotate 20
counter-clockwise, as viewed in Fig. 5. The shape
of the slot 455 in the locking lever 443 is such that
whenever the shaft 452 and the arm 453 rotate
in either direction away from the normal posi
tion, the locking lever 443 is rocked counter 25
clockwise to its unlocking position. The rocking
of locking lever 443 removes the upper end of
the lever out of the path of the resetting seg
ment 44! and simultaneously withdraws the de~
tents 441 from the pinions attached to the date 30
setting wheels 80, thereby unlocking the resetting
mechanism common to the check printing counter
and detail strip printing counter, and unlocking
the date wheels in the check printer. When the
auditor turns his key in the lock M6, the shaft 35
MI is shifted to the left and the shaft 452 is
rocked clockwise, as viewed in Fig. 5, thereby
rocking the arm 453 upwardly; but the locking
lever 443 is rocked counter-clockwise just as in
the case when the manager’s key is turned.
40
The resetting segments H10 and MI are oper
ated by a resetting lever 451 which is pivoted at
458 to the end frame I2 and which has a forward
end projecting through a slot formed in the cab
inet I9. Cooperating with the resetting lever 451
is a segment 460 pivoted on the frame I2 and 45
slotted to receive a pin 46I on the resetting lever.
The segment 460 is provided with teeth 463 en
gaging a pinion 464 secured to a shaft 465 loosely
supported by the end frame I2. Also secured to 50
the shaft 465 is an arm 465 which is connected
by a link 461 to the free end of the resetting seg
ment H10. The resetting segment N10 is piv
otally mounted on a stud 468 which is supported
by the frame H0.
The operation of the resetting mechanism for
the consecutive counters of the check printer and
detail strip printer is as follows:
Assuming that the locking lever 443 (Fig. 5)
has been rocked counter-clockwise by the oper
ation of either the manager’s or the auditor’s
key, the resetting lever 451 will be free for oper
ation. When the lever 451 is lifted, the seg~
ment 455 is rocked counter-clockwise and, by
virtue of the link 410, rocks the resetting seg 65
ment MI in the same direction. During the up
ward movement of the resetting lever 451, the
shaft 53 is rotated clockwise by the segment 44I ,
thereby restoring to zero the consecutive counters
60 for the check printer.
Referring to Fig. 4,
the shaft 53 is provided with a series of notches
41 i, each of which is in alignment with a spring
pressed pawl 412 pivoted on its associated counter
element 50. When the shaft 53 is rotated clock
wise, the notches 41I pick up the pawls 412, there
