Improvements in Cash Registers.
We, THE NATIONAL CASH REGISTER COMPANY, LIMITED, of 337, Strand,
London, W.C., Manufacturers, do hereby declare the nature of this invention a
communication to us from abroad by THOMAS CARNEY, of Dayton, State of Ohio,
in the United States of America, and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-

This invention relates to improvements in cash registers and has
particular relation to the type of machine described in Specification of Letters
Patent No. 10213 of 1893.
One of the several objects of the invention is to provide the class of machine
specified with counters any one of which may be brought into connection
with the registering mechanism at will so that the amounts of the different
characters of transactions may be thrown into separate counters.
Another object is to provide the class of machine mentioned with printing and
indicating means for both printing and indicating which of the counters each
transaction is recorded upon.
The invention will be first described with reference to a machine with two
counters.
In the appended drawings forming part of this specification, Fig. 1 represents

after referred to.
In the drawings 1 represents the frame of the machine; 2 the operating keys;
3 the counters; 4 the special indicator and 5 the printer. The respective
counters 3 are mounted upon pivoted frames 3* so that when said frames are
tipped forward the gears of the counter wheels will be brought into mesh with

the segmental operating gears 7, 8 and 9 and 10, 11 and
gears 10, 11 and 12ª are operated substantially in the same manner as described

page_text: in the Specification of the said Patent No. 10213 of 1893 and transmit their
respective movements to the gears, 7, 8 and 9 as follows: The gear 12 meshes
with a pinion 32ª mounted on a shaft 33" which carries a similar pinion 34
which in turn meshes with the rack 9. The gears 7 and 10" are both fast on
the shaft upon which they are mounted while the gears 8" and 11 which are
loose on said shaft are coupled by a rock frame 30. The pivoted frames 3ª are
provided each with a laterally projecting stud in the form of a spring pressed
plunger mounted in the respective frame in such a way that it may protrude to a
definite distance from said frame or may be pushed further into the frame so as
not to project so far therefrom. These plungers are formed respectively with
reduced portions and they co-operate with pivoted throwing levers 18 and 19
respectively so that when either plunger is in such position that its reduced
part is in the path of its corresponding lever 18 or 19 the frame 3 is not moved,
but when it is in such position that its full part is in the path of the lever them
the movement of the lever causes the movement of the frame 3".
The plungers on the frames 3" are adapted to be adjusted (so that the respective
frame is either rocked or not) by a shifting device comprising a longitudinally.
movable rod 6. (Figs. 5, (b) provided with a coil spring 6 which engages a
suitable projection of the frame. Three arms 7, and 9 respectively are
mounted on said rod so that the two latter will engage and operate the two
spring pressed plungers 10 mounted in the respective counter frames. Each
of the pivoted throwing levers 18 and 19 is suitably pivoted upon its respective
counter frame and is provided at its inner end with an antifriction roller 16
which engages one of two cams 13 and 14. mounted upon the rotation shaft 25.
Cams 13 and 14b are also mounted on said shaft near each of the afore-said
cams and are adapted to engage respectively with anti-friction rollers 29
mounted on rigid arms 28" of its respective counter frame to throw the counter
frames back in place after they have been thrown forward by the action of the
levers 18 and 19. The before mentioned arms 7 and 9 are provided with studs 11
and 12 respectively; the latter operating in a suitable apertured bracket 13
secured to the frame so as to prevent any twisting of the rod G; and the former
being adapted to enter a socket 14 in one of the counter frames and thus lock
this frame in its retracted position when the remaining counter is being operated.
This remaining counter is in turn locked in position at the proper time namely,
when the other counter is free, by a stud 15 mounted on its frame and adapted
to enter an aperture 16 in the arm 9 when said arm is moved towards the same.
The longitudinal movement of the shifting rod 6 is effected by a key 17 compris-
ing a slidable rod having a suitable head and mounted in suitable guides so that
its inner bevelled end will contact with the bevelled end of the said shifting
rod, the relative angles of the bevel ends of the two rods is such that the
rod 17 has a greater movement than the rod 6 so as 'to permit the desired move-
ment of said latter rod and still move the rod 17. sufficiently to properly co-
operate with its locks. hereinafter described. The said key rod is provided with
a nut or washer 19 which is so arranged as to be locked either in its inner or its
outer position by the notched bolts of locks 20 and 21 mounted respectively
above and below the key rod on the main frame.. It will be observed from the
above description that the key for controlling the counters may be locked in
either one of its adjusted positions by the persons holding the keys for said
locks, and that the movements of said keys will cause one of said counter frames
to become locked and simultaneously release the remaining frame.
The key
normally stands in its outer position but when it is pressed inward to shift the
rod G it does not immediately return again upon being relieved of pressure as
the said rod.6 is restrained against the tension of its spring by a pivoted spring
pressed latching or locking lever 22 mounted on the main frame and arranged
to normally engage a bevel ended nut 23 secured to said rod 6. After the inner
end of the lever has become caught over the nut 23 upon the longitudinal movement
of the rod 6, the latter is locked in position and is only released by said lever

page_text: approximately at the end of the operation of the register by a cam 24 fast on
the rotation shaft 25 of the machine and arranged to engage and depress one
arm 22 of the inner yoke end of the said lever; said yoke embracing said
cam. The upper arm 22 of said yoke is adapted to lock the rotation shaft 25
during the first movement of the rod 6 by being forced in front of a shoulder 22°
on said cam by the bevelled nut on said rod. After the latching lever has passed
over the bevel nut the arm 22b disengages from the shoulder 22° and permits
the shaft 25 to operate. By the above described devices the operations of the
machine is prevented until the counters have been fully shifted. By this
means the key 17 is returned to normal position at each operation of the machine
unless locked in its adjusted position by the aforesaid locks. The peculiar
notched construction of the bolts of the respective locks permits of said bolts
being made of sufficient width for the desired strength and at the same time
allows the washer 19 a minimum amount of movement in its co-operation with
said bolts. In addition to the above mentioned parts, the rod 6 is provided near
one end with an angular plate 26 having a diagonal slot 27 formed therein and
adapted to receive a pin 28 mounted on a crank arm 29 which in turn is secured
to a printing segment 30 mounted on a sleeve 31 and of similar construction to
the regular printing segments described in the above mentioned patent. The
segment 30 is provided with two printing types of characters which represent
the characters of the two counters so that a character corresponding to the
counter being used is printed on the detail strip in alignment with the amount
of the transaction that has been registered on said counter. In addition to the
above described devices the rod 6 is further provided with two oppositely facing
nuts 47 and 48 the office of which is to throw either one or the other of the operat-
ing devices for the auxiliary special counters 49 and 50 into operative position.
Each of these operating devices comprises a pivoted lever 51, Fig. 3, an operat-
ing lever 52 pivotally mounted thereon and connected thereto by a coil spring 53
and an operating bar 54 fast to the usual key coupler. This bar is provided with
a pin 55 which projects into an angular slot 56 formed in the lever 52 whereby
when the key coupler is elevated said pin is depressed and if lying in the upper
end of the angular slot will force the lever 52 downward and operate the special
counter connected thereto. The coil spring 53 normally draws the lever 52
forward out of operative position but when said. lever is forced backward by
one of the bevel nuts the pin 55 enters the upper portion of the angular slot in
said lever so that when the bar 54 moves downward the lever 52 will also move
correspondingly.
We provide one of these auxiliary special counters for each special totallizing
counter and the operation of shifting said totallizing counters also shifts: the
operating devices of these special counters. The office of said auxiliary special
counters is to record respectively the number of times their respective totalizing
counters are operated so that the number of transactions recorded upon each
totalizing counter may be ascertained at. a glance. In connection with the two
totalizing counters shown in the present machine it is very desirable to provide a
special indicator for indicating which counter each transaction is being registered
upon. In the present instance we have illustrated a bar and café indicator in
connection with the two counters which register the respective sales in the
corresponding departments. This indicator is located above the regularamount
indicators and comprises a rectangular indicator proper 4, and a supporting and
operating rod 33 upon which said indicator is rigidly mounted. The opposite
ends of this rod are journalled in the side portions of the frame so as to support
the indicator in a horizontal position above the regular tablet indicators and
slotted arm 34 is rigidly secured to one end of said rod so as to receive a pin 35
mounted on a vertical slide. 36 which in turn is mounted in 'suitable guides on
the main frame. This slide extends down through the indicator stem guide
plate and is surrounded by a coil spring 37 which bears against the underside
of said indicator stem guide plate at one end and against a pivoted bell crank
.a

page_text: not
pawl 38 (Fig. 10) mounted on the slide at its opposite end so as to normally
force the slide, downward and the pawl outward at its lower end (see Fig.. 10).
The downward movement of the slide is limited by a pin 37" (Fig. 3) mounted
on the frame and arranged to engage a shoulder 376 formed on said slide. When
the slide 36 is raised the, pawl 38 is forced inward as it passes the usual indicator
rock bar 39 since the movement of said bar is not intended to take place except
in connection with the regular indicators, whose movement is subsequent to the
movement of the special indicator slide because the ordinary keys are
intended to be operated till the special key has been operated if necessary. The
said rock bar catches under the pawl 38 in the same manner as it does under the
projections of the indicator tablet stems and thus holds the slide 36 in an
elevated position until said bar is actuated in the usual manner for releasing the
indicators, when it drops if not otherwise supported. The raising of the slide
is accomplished by means of a slotted arm 40.mounted on a sleeve 41 and engaging
a pin 42 projecting laterally from said slide. The said sleeve is loosely mounted
upon a transverse shaft 43 and is provided with a hook. arm 44 which is so
arranged as to be engaged by a pin 45 secured to an arm 46 fast upon one of the
counter frames. By this means when the counter frame carrying said arm is
rocked the slide 36 is raised and thus turns the rectangular indicator so that
the duplicate indicators upon the top and bottom will be brought into view at
the front and rear of the machine. If neither of the locks for the special key are
used said key will be automatically returned to its outer position at each opera-
tion if it has been forced inward. The indicator will of course also return auto-
matically to its normal position upon the release of the shifting bar at each.
operation.
It will be seen by the foregoing description that when the machine is to be
used by clerks who relieve each other and each clerk is to have a separate
counter that the keys of the locks will be given to the respective clerks so that
when one clerk leaves he will unlock his lock to shift the special key and bring
the washer 19 between the two locks and the levers into inoperative position.
(See Fig. 2). Either clerk may now throw his counter into operative position
by unlocking his particular lock but he cannot throw the counter of his fellow
clerk into such position. One clerk is thus prevented from registering upon
the counter of another. If the clerks are working simultaneously and it is
desired to keep the bar and café, or any other accounts separate the locks are
unlocked and the counters thrown into or out of engagement at each operation
of the machine by the operation of the special key. As said key normally
throws all sales into one counter it is not necessary to press the said key until
it is desired to throw the sales into the other counter; and when such action
is necessary the devices are automatically returned to normal position as above
described. Besides temporarily indicating which of the special counters is being
employed for a certain transaction a permanent record of the counter into which
each amount is thrown is printed in connection with such amounts upon the
detail strip of the printing machine.
In the modified form of this invention shown in Figs. 7 and 8 and which is
intended for use principally where two persons are using the machine at the
same time the rod 17 is shortened and the locks 20 and 21 and the lever 22 and
co-operating parts omitted. Further the said rod 17 is provided with a laterally
projecting stud 50% which is adapted to operate in a slot 51" formed in a
lever 52 which is in turn pivoted upon the main frame. This lever is also
formed with an inclined slot 53 into which projects a stud 54 mounted on the
special shifting key 55b. It will be observed from the above that when the said
special key is depressed the stud 54" will travel down in the slot 53 and thus
rock the lever 52ª on its pivot which action will cause the rod 17 to move inward
and shift the counters as before described. The aforesaid key 55b does not
receive its full stroke upon its initial movement but is only depressed until a

page_text: pin 56 mounted thereon contacts with a stop arm 57 mounted on the key coupler.
The said key is held in this particular depressed position by a pivoted latch 58
which engages a notch 59 formed in a segmental extension 60 of the lever 52".
The upper portion of the key to the rear of its pivot is reduced as at 61'so that
said special key may be operated to such an extent as to cause its hook end 62
which is similar to the regular keys to be engaged by the key coupler when the
latter is raised by the operation of the numeral keys.
The afore-said key coupler is further provided with a rigid curved arm 63
which if one of the numeral keys" has been depressed passes down behind a.
pin 64 mounted on an extension 65 of the lever 52" so as to prevent the rear
movement of lever 52" and thus also prevent the operation of the special
key after a numeral key has been depressed. As the lever 52" is held in
position after being operated by the latch 58 it becomes necessary to provide
some means for releasing said latch. This we accomplish by pivotally mounting
said latch on a swivel stud 66 suitably mounted on the frame, and providing the
same with an extension 67 (Fig. 8) having an incline wall which lies in the
path of an incline projection 68 mounted on the special key. The said latch-
ing pawl is held in its normal latching position by a vertical coil spring 69 and
a horizontal coil spring 70 (Fig. 8). When the special key is fully depressed by
means of the key coupler as before described, the projection 68 strikes the
incline wall of the extension 67 and forces the latch to one side out of the
notch 59 so that it snaps up beside the extension 60 and cannot again enter the
notch until the lever 52" has returned to normal position and been again
operated.
It will also be observed that the special key is returned to its normal position
after each operation of the machine and therefore all the transactions will be
registered upon one counter unless the key controlling the other is operated.
In this modified form of our device the key rod 17 is provided with a lateral
projection 71 having an incline end against which an antifriction roller 72
mounted on a bell crank lever 73 abuts. The said roller is normally held in
contact with said block by a coil spring 74 which connects the lever 73 with the
frame. Said lever is further formed in one end with a slot 75 into which
projects a pin 76. mounted on a lever 77 which latter is in turn mounted on a
sleeve 78 carrying a printing segment 79. This mechanism is intended as a
modified form of the printing segment and co-operating parts before described.
As the rear end of the special key is reduced as at 61, the key coupler will not
force said key back to its original position as said coupler will be arrested by the
regular keys before such position is reached and we therefore provide said
key with a spring pressed stud 55d which engages the under side of said coupler
and thus normally forces the key downward.
We shall now proceed to describe an arrangenfent of the same invention where
more than two counters are combined with one and the same series of keys in
order that any one of them may be operated by said keys as desired, and have
illustrated the invention as performed for four counters in a machine which is
adapted for registering four different kinds of transactions, for example cash"
charge received on a/c" paid out."

•
In these drawings 20 represents the frame of the machine, 21 the operating
amount keys, 22 the indicators, 23 the independent department counters, 24 the
special counter keys, and 20° the totalizing cash counter.
As the operating keys, indicators, and other parts are of substantially the
same construction and operation as the machine described in the aforesaid
specification of British Letters Patent No. 10213 of 1893, I will refer to such
patent for a detail description of these parts which are well known in the art
and need no further detail description in this specification.
It will however be understood that the operation of any of the amount keys
is intended to be registered at will upon some one or other of the four counters,
just as in the previously described machine it was to be registered on the one or
other of only two counters.
It is thus apparent, that while in the machine previously described, it was
only necessary to duplicate the sets of operating segments with which the
counters are alternately brought in gear, in the present machine in which four
counters are used it is necessary to have four sets of operating segments, and to
couple up the similar segments in the four sets with each other so that the
similar segments may work simultaneously in all the sets when one of the
amount keys to which they relate is depressed.
We do not necessarily confine ourselves to any particular mechanism for this
purpose. In the previously described two-counter machine two similar seg-
ments are fixed, on the shaft, two other similar segments are loose thereon and
connected by a rock frame, while the remaining two similar segments are loose
and connected by another shaft and two pinions, all as described in the com-
mencement of this description. In the following description of the four-counter
machine we have described a somewhat similar apparatus, that is to say, one
set of four segments is fast on the shaft, the second set loose on the shaft and
connected by a rock frame while those of the third set, also loose on the shaft,
are connected, in this instance, by another rock frame instead of by an exterior
shaft carrying pinions engaging the segments.
We lay no special claim to this modification since it is clear that it is only a
mechanical equivalent of the former construction. It will however be convenient
to describe this mechanism more in detail in order that its construction may be
more readily understood and reference may therefore be made to Figs. 15 to 19.
The amount keys 21 in the present invention carry graduated standards 25
(Fig. 12) similar to those of the patented machine No. 10213 of 1893. Theso
standards, however, in the present instance are adapted to engage a series of
nested yoke frames 26, 27, 28 and 29 which frames represent respectively the
four banks into which the keys are divided as shown in Fig. 11.
As these frames 26, 27, 28 and 29 are nested or lie one within the other I will
commence my description with the innermost or units of cents frame 26.
This frame, as. shown in Figs. 15 and 19 is mounted rigidly upon a rock
shaft 30 by means of a straight arm 31 and a curved arm 32; said arms being
connected to segmental counter operating gears 33 also fast to said shaft.
The shaft further supports and operates other gears 33. All of said gears are

page_text: so positioned on said shaft as to co-operate with the pinions of the units of
cents counter wheels of the respective counters as hereinafter described.
The said frame 26 supports a short transverse bar 34 with which all of the key
standards 25 of the units of cents bank of keys co-operate to elevate it different
distances and thus rock the frame according to the value of the key operated.
This operation is substantially similar to the operation of the parts described in
the specification of the afore-said patent.
The bar 34 supports two pivoted arms 35 connected by a cross rod 3 and
norinally drawn forward by a coil spring 37 which connects said rod to the
frame.
The arms 35 normally lock under lugs 38 (Fig. 12) formed on the main frame
and thus prevent any jumping or throwing of the registering frames by sudden
operation of the keys.
When a key is operated its standard 25 in being elevated engages a cross-
bar 25 and is thus forced forward until striking the rod 36 it in turn forces it
forward and thus disengages the arms 25 from the lugs 38 and frees the frame 26.
The frame 27 shown in Figs. 16 and 19 is similar to the frame 26 but is
mounted loosely upon the shaft 30 by means of a series of curved arms 39 con-
nected to said frame and also to a cross bar 40 rigid with said frame. Each of
the arms 39 carries a segment rack 41 similar to the segments 33 and
positioned as to co-operate with the pinions of the tens of cents counter wheels of
the respective counters.
SO
The frame 28 shown in Figs. 17 and 19 and which represent the units of dollars
bank of keys, is substantially like the frame 26 with the exception that it is sup-
ported in position by a transverse bar 42 which extends under the arms 32 and 39.
This bar is in turn supported in position by a series of segmental racks 43
journalled on the said shaft 30 and so positioned as to cooperate with the pinions
of the units of dollars counter wheels of the respective counters..
The frame 29 of the tens of dollars bank of keys is as shown in Fig. 18 sup-
ported in position by a segmental plate 44 and a curved arm 45; the latter being
to allow the passage of the bar 42. The said plate and arm 44 and 45 are con-
nected to a cross bar 46 which in turn is connected to a series of segmental
racks 47 and is provided with a journal hub 48. This hub and the racks 47
are journalled upon the shaft 30 and the racks are so positioned as to cooperate
with the pinions of the tens of dollars counter wheels. By reference to Fig. 19
it will be seen that the respective registering frames are so arranged as to lie
side by side and in alignment with the key standards of their respective banks
of keys.
The elevation of a key standard of course lifts its respective registering frame
and upon the return movement of the key draws the same downward until it
approaches the termination of its stroke when it disengages from it leaving said
frame to continue its movement by gravity. In order to make the final return
movements of the frames positive I provide the rotation shaft 62 near each end
with a cam lug 62" and 162" (see Figs. 15, 16, 17 and 18). The lugs are arranged.
to engage fingers 62 and 162b pendant from the respective, rack segments and
are so positioned that this engagement will take place as the final movement
of the machine is made and thus fully move said racks back to their normal
positions.
It will be observed from the above description that the relative locations of
the respective segmental racks are such that the same are grouped in four series
one for each of the counters 20 and 23 so that any one of said counters may be
thrown into mesh to receive the registration from its respective sets of tracks.
Both the amount and the special transaction keys are of substantially the same
construction as described in said patent and co-operate in substantially the same
inanner with the indicators 22 which construction is well known in the art and
needs no further description here.
no.

page_text: The rear ends of the amount keys as shown in Fig. 14 co-operate with a series
of pivoted hangers 50 in the usual manner to prevent the operation of more
than one key in the same bank at the same time. As these hangers do not
engage the special keys however, I provide a series of special hangers 51 con-
nected in pairs by link rods 52. When one of the special keys is operated the
hangers 51 engaging the same are moved and through the links 52 bring all the
remaining special hangers in the paths of the special keys to prevent operation
of the latter.
Having now described the construction for providing duplicate series of simul-.
taneously operated racks movable according to the values of the operated keys I
will pass on to the description of the counters which cooperate with said racks
and as these counters are all practically alike the description of one will suffice
for all.
"
The three left hand counters 23 represent respectively "charge "received on
account," and "paid out" transactions, while the right hand counter 20" repre-
sents the cash transactions and is rendered inoperative when any of the remain-
ing counters is set for operation as will be hereinafter more fully described.
Each of the counters comprises a frame 53 (Fig. 21) and a series of counter
wheels mounted on a shaft which in turn is journalled in said frame. The said
frame is pivotally supported in position in the main frame by trunnion pins 56
which are mounted on said main frame and project into suitable sockets formed
in said counter frame.
Each counter frame is further provided with a spring pressed plunger 57 (see
Fig. 21) mounted in a socket of the same and formed with a notch 58 and a bevel
end 59. A lever 60 is pivoted on each counter frame and is adapted to engage
the plunger 57 to rock the counter frame forward when said lever is operated.
This operation of the lever is effected by a cam grooved disc 61 mounted on the
rotation shaft 62 of the machine, and into which projects a pin 63 mounted on
said lever. Said lever 60 is formed with a circular opening 60 through which
one of the trunnions 56 projects.
When the plungers 57 of the counters 23 are in normal positions the notches 58
are in alignment with the levers 60 so that the operation of the latter will not
rock the counters forward into operative position while the normal position of
the plungers 57 of the counter 20 is such that its notch 58 is out of alignment
with its lever 60 whereby the operation of said lever will cause it to engage the
plunger and force the counter forward.
From the above it follows that when a plunger of one of the counters 23 is in
its normal position its respective counter will not be rocked to operative position
by its lever 60 but when the plunger is forced into its socket the notch is moved
out of alignment with the lever 60 with the result that when the latter is
operated it will engage said plunger and thus rock the counter frame forward.
The above, except the bevelled ends of the plungers 57 is the same as in the
previously described two-counter machine.
The plungers of the counters 23 are set to effect the rocking of the counters
as above described by the operation of their respective keys 24.
"
Each of the keys 24 is substantially of the same construction as the regular
amount keys with the exception that it has no bar or operating standard 25.
The extreme left hand key 24 which represents the " charge transactions is
provided with a rigid yoke frame 64 which is journalled on the key shaft 21"
(see Fig. 20) and is provided with a rigid forwardly extending arm 65 carrying
an anti-friction roller 66 at its forward end. This roller projects into a cam
slot 67 formed in a lever 68 which is journalled on a transverse rock shaft 69
so that when the said special key is depressed and the yoke 64 rocked said lever
will be correspondingly operated.
Said lever 68 is formed with a curved arm or extension 70 (see Fig. 13) having
a bevelled end 71 better shown in Fig. 11 and which, when the arm is moved
forward engages the bevel end 59 of its respective plunger 57 and thus forces

page_text: the same back into its socket, in which position it will be engaged by the lever 60
to rock the counter forward.
The second special key 24 for the "received on account" transactions is con
nected to its lever 56 in a similar manner to the above mentioned key; its con-
necting yoke 64 being located above instead of below the keys as is the first
mentioned yoke (see Fig. 13).
The third special key for the "paid out" transactions is provided with an
antifriction roller 72 (see Fig. 11) which extends into the cam slot 67 of its
respective lever 68 and thus operates the latter directly without the intervention
of a yoke as employed in connection with the above mentioned keys.
While the levers 68 are loose on the supporting shaft 69 they are arranged to
rock said shaft in the following manner.
Each of said levers is provided in proximity to the shaft 69 with a lug 73
(Fig. 20) which is arranged to strike a similar lug 74 formed on a sleeve 75
fast to said shaft. By means of this peculiar connection a lever 58 may be
rocked to operate the shaft 68 without operating any of the remaining three
levers 68, so that the different keys 24,upon being operated will rock the shaft 69
to a greater or a less extent according to the formation of the cam slots in their
respective levers 68.
I have herein before described the connection of all of the special keys with
the shaft 69 except the no sale" key which is the extreme right hand key of
the machine. The lever 68" of this key as shown in Fig. 12 is fast to the
shaft 69 so as to move therewith both upon the operation of its own key and also
upon the operation of any of the other special keys. Thus the movement of any
of the special keys causes the shaft 69 to be rocked and the lever 68ª to be
rocked with it, but, since the cam slots 67 of the levers 68 68 68 and 68* are of
different curvature the angular distance through which the shaft 69 is rocked is
different for each special key and consequently the angular distance through
which the lever 68 is rocked will differ according to which lever 68 is operated,
or if lever 68ª
operated by its own no sale" special key, it is rocked through
yet a different angular distance.
56
Thus the extent of movement of the lever 68 differs upon the operation of the
several keys and a graduated movement for operating the special printing
wheels 117 (see Fig. 11) is thus secured. The communication between these
wheels and the lever 68° is established through the medium of a sleeve 77 (see
Fig. 11) upon which the wheels are mounted and which is provided with a
segmental pinion 78 meshing with a segmental rack 79 formed on said lever 68
as shown in Fig. 12. By this means the operation of a special key will adjust
the printing wheels 76 to print the proper character designating the character of
the transaction...
The printing mechanism used in connection with this invention may be of any
desired construction.
no sale"
In order to return the shaft 69 and all the levers 68 to normal position after
the same have been operated I provide a coil spring 80 (Fig. 12) connected at
one end to the main frame and at the other to the lever GS of the "
key which lever is fast to the shaft 69. When the shaft is rocked the spring is
put under tension to return the parts when they are released.
"
The movement of the lever 68 of the no sale" key upon the operation of any
one of the special keys results in throwing out the totalizing counter as said
lever is formed with a bevel ended arm S which is arranged to force the
plunger 57 of the cash counter into its socket and thus prevent the counter being
thrown forward by its lever 90.
The rocking of the shaft 69 upon the operation of the special keys also affords
means for throwing out a special counter $2 which is intended for registering
the number of cash sales (see Fig. 13). This counter is of any suitable con-
struction arranged to add one each time it is operated. The arm 83 carrying
the operating dog 84 of this counter is provided with an anti-friction roller 85

page_text: '
which projects into a slot 86 formed in a pivoted spring pressed arm 87 mounted
on the usual key coupler 88 employed in this class of machine.
By this means it will be observed that upon each reciprocation of the key
coupler one unit will be added to the counter 82. This is true of all transactions
except such as are accompanied by the operation of a special key and the con-
sequential rocking of the shaft 69. This shaft carries an arm 89 formed at its
rear end with a bevel edged nose 90.
When the shaft is rocked as above
described upon the operation of a special key this bevel nose 90 engages the edge
of a lever 91 and rocks the same on its trunnions to cause its upper end to
engage the arm 87 and force the same out of cooperative relation with the roller 85
"so that the counter will not be operated upon the movement of the coupler as
aforesaid.
The said lever 91 is formed with an aperture 92 through which the key
shaft 21 projects. Said lever is provided with two trunnion screws 93 which
‹ engage a collar 94 fast to said shaft 21" and thus pivotally support the lever.
The lower end of the lever is slotted at 95 to receive the shaft 69 which forms
a guide therefor.
It has before been described how the counters are selected and adjusted to be
rocked into connection with the counter operating racks by the cams G1, we do
not confine ourselves to any particular description of counters.
The application of this invention is of course not limited to counters for
receiving the amounts of special transactions as the same may be employed
"equally well as department counters for keeping separate accounts of different.
class of goods.
