Improvements in Cash Registers and Indicators and Check Tills.
I, GEORGE CROYDON MARKS, of 18, Southampton Buildings, London, W.C.,
Consulting Engineer, do hereby declare the nature of my invention in cash
registers and indicators (a communication from abroad by The Hallwood Cash
Register Company, of the Wheeler Building, Columbus, Franklin County, Ohio,
United States of America, a body corporate), and in what manner the same is to
be performed, to be particularly described and ascertained in and by the follow-
ing statement:-
This invention relates to cash registers and indicators of the kind referred to in
the Specification of Letters Patent No. 23920 of 1896, and it has for its object
to provide a cash register by which transactions of different characters in any
business may be registered separately, and such different transactions as properly
belong together added into a grand total so that the combined amount of all sales
or transactions of a particular kind may be at once determined. The construction,
however, is such that transactions which do not properly belong to the grand total
may be registered or recorded independently. The arrangement is such also
that no registration can be made unless it be placed in one of the particular
departments, thus particularizing each kind of transaction, proper indicators
being so connected with the mechanism that the particular kind of transaction
as well as the amount of the transaction shall be indicated at the time the regis-
tration is made.

page_text: as modified to correspond to the English system of money, pounds, shillings and
pence.
In carrying out this invention a keyboard is employed in which the keys are
arranged in sets or series, the respective keys in each set. or series being numbered
from one to nine, and each set or series represents a different denomination, such
as units, tens, hundreds, when the amounts registered are in the decimal system,
or they will be modified to represent the denominations of money used in the trans-
actions.
As shown in the drawings and for convenience, this keyboard is placed on the
lefthand side of the machine as it appears when the operator is facing the machine,
the space within the machine to the right of the keyboard being employed for the
registering mechanism, which consists of wheels in the nature of counting wheels.
These wheels are divided into sets or groups and each set or group has a wheel
corresponding to the denominations which are represented on the keyboard, and
there are as many sets or groups as there are different transactions to record.
In the simplest form of this invention these registering wheels of all the groups
are arranged on a single shaft, which extends entirely across the space given up
to the registering mechanism so that the wheels are turned about a common -axis.
There is also journaled on this shaft or axis a series of swinging frames, which
consist, in effect, of bars having each end turned inwardly at rightangles and
perforated to receive the axis of the registering wheels, the main body or bar
extending across the peripheries of all the wheels. There is one of these frames
for each series of keys and each frame has a set of stops corresponding to the keys
of the series.
Each registering wheel has a pawl lever and pawl and all the pawl levers and
pawls of one denomination are adapted to contact with and be operated by the
frame corresponding to that denomination. Means are provided for
releasing each one of these frames whenever a key of its denomination
is operated. Means are also provided for preventing the operation
of all the pawl levers of each department or group of registering
wheels except when it is designed to register in that department or group. An
exception is made, however, for the total registering device, which is adapted to
operate with each transaction except that it be a transaction of unusual character,
in which case means are provided for preventing the operation of the total
registering device at the same time the group or department employed for register-
ing the unusual transaction is thrown into operative position.
In order to insure accuracy in the registration and prevent conflict in the
registrations of the different departments or groups, interlocking devices are
employed between the registering keys of the main keyboard and the keys which
control the department registers.
This machine is designed to be operated by the opening and closing of the
drawer. The drawer is normally closed and locked and is unlocked whenever
one of the special or department keys is operated; but the department keys are
normally locked and are unlocked by the operation of the cash keys or registering
keys of the main keyboard. Inasmuch as the operation of registering is effected
by the opening and closing of the drawer, the pressing of a cash key or register-
ing key on the main keyboard simply sets the mechanism into operative position
and unlocks the department keys. The operation then of a department key releases
the drawer and releases the registering device of that department so that the
swinging frames will drop down until they contact with the registering keys which
have been operated and remain in this position until the drawer has been closed.
On the closing of the drawer these frames will be carried back to their normal
positions by the movement of the drawer and will carry with them the pawl levers
of those departments or registering groups which have been released and in this way
produce the necessary movement of the registering wheels to effect a registration.
In the said drawings, A. represents the keyboard on the left of the machine;
B represents the main registering or totalizing device; B1 B2 represent the depart-

page_text: 66
ment registers entering into the total, such as
"cash sales,"
amount received
on account," etc. B3 is a department register for transactions of a different nature
which do not go into the total; for instance, such as "paid out." It will be noticed
that the registers B1 and B2, which go into and form a part of the grand total, are
placed between the main register B and the keyboard, while the registering
device 133, which is independent, is placed at the right of the main register or on
the opposite side from the keyboard. It must be understood that any number of
these registering devices can be employed, but all those which enter into and form
a part of the grand total will be placed to the left of the total register and all
those which are independent and do not go into the grand total will be placed
to the right of the main register, assuming that the keyboard is on the left. There
is no reason why these positions may not be reversed and the keyboard be placed
on the right, in which case the positions of the registers heretofore described will
be reversed.
On the keyboard, the different sets of keys representing different denominations
are marked A1, A2, A3, A4 Each of these keys consists of a button a and a stem a',
with a spring a² surrounding the stem to return the key to its normal position
after it has been operated.
The drawer which furnishes a receptacle for the cash and also performs an
important function in operating the parts by its opening and closing, is marked C,
and the swinging frames which are released by the keys and operated by the open-
ing and closing of the drawer to produce a registration are marked C1, C2, C3, C4,
there being one of these for each of the series of keys A1, A2, A3, A+
On the lefthand or keyboard end of each one of the swinging frames there is
placed a notched segment c, which stands in the same plane with the series of
keys which correspond to that frame, and each one of these segments has as many
notches as there are keys in the series. In the machine which I have illustrated
there are four sets or series of keys with nine keys in each set or series. There
will therefore be four of these segments c and each will contain nine notches.
The segment c, as well as the key supports, is placed eccentric to the axis of the
swinging frame and is so arranged that each one of the notches will correspond
with a particular key, and when the frames are released the notches of the segments
will engage with only one of the keys to be depressed and this arrangement is such
that when the key marked "1" is depressed the key will engage with the first
notch and the segment be limited to an angular movement which will allow the
registering wheel to be moved one notch or unit which if the key marked "9"
is depressed the angular movement of the segment will be sufficient to allow of
the registering wheel moving through nine such notches or units.
The registering wheels in each set are each formed with teeth and these teeth
correspond to the units of movement of the frame. Each set or group of register-
ing wheels is substantially a duplicate of the other set and consists of a number
of wheels corresponding to the number of the swinging frames. Each of these
wheels, when the decimal system is used, is divided into one hundred spaces and
has the same number of teeth. Each one of the wheels b, except the highest
denomination, is, however, divided into ten sections of ten notches or spaces each,
numbered from 0 to 9, and at each one of these intersections there is placed a pro-
jection 6', which is used in transferring amounts of one denomination to a higher
denomination in the manner hereinafter specified. A pawl lever journaled on
the main shaft or axis 1 carries a spring-pressed pawl 63, and each of these pawl
levers has a downwardly-projecting stem 6, which rests on one of the bars or
frames C1 C2 C3. The stems are fixed on the pawl levers to permit each of the
pawl levers to drop independently when the frame which supports the same is
released without the pawl lever coming in contact with any other frame which
may not be released. Each of the pawl levers 2 is provided with an additional
arm 65, which extends downwardly and is adapted to contact with a pivoted
latch, D D D D³, pivoted on a suitable shaft 2, which extends across the frame.
Each of the latches, D¹, D³, D³, normally engages the arms b5 of all the pawl

page_text: levers of its own register. The latch D, however, is normally disengaged from the
pawl levers b which correspond to the main or totalizing register B. The arms 65
for this register are provided with notches 66, in which the latch D is adapted to
engage under circumstances hereinafter to be mentioned. Each of the latches
with the exception of the one D is provided with a projection d, adapted to be
engaged by a key-stem e of what is termed the department or special keys. These
key-stems are supported in suitable bearings and are provided at the outer ends
with buttons e, by which they may be readily operated to depress the latches D¹
D2 D3 and thus release the pawl levers of the respective registering devices.
The drawer is normally held closed by a drawer lock or hook f, which is pivoted
to a suitable part of the frame at f¹ and is provided with a projecting bar f
which extends in proximity to the latches D1 D2 D3, and each of these latches is
provided with a finger, which rests under the bar f, and is adapted,, when the
latch is turned, to raise the bar and thus release the drawer. The drawer when
released is adapted to be expelled by a spring g in the usual manner.
I shall now proceed to describe the connections between the keyboard and
the registering wheels for effecting the registrations indicated by the manipula-
tions of the keys of the keyboard, reference being had particularly to Figures 2,
4, and S. Each of the key stems is provided with a laterally projecting pin a³,
which pins are adapted to project through slotted openings at in a guide plate a,
arranged at the side of each series of keys. There is arranged at the side of each
of these guide plates two swinging plates af and a, which are hung on the main
shaft or axis 1. Each of these plates has projections a8 on its periphery and
these projections are inclined or beveled so that the beveled face of each extends
across one of the slotted openings at in the guide plate 5. The plate a is pre-
ferably made solid and is provided with a pin a³ which projects through the
plate af, the latter being preferably made open. The projections as on the plate a
are straight near the periphery of the plate, while those on a are undercut, as
shown at a¹0, so as to form hooks, which, when the keys are depressed, will hook
over the pins a³.
Each of the notched swinging segments c is provided with a laterally-projecting
pin c, adapted to be engaged by the hook-shaped arm of a bell-crank lever
pivoted on a shaft or rod 3; the other arm of said bell crank lever being
adapted to rest in contact with the pin a. Each of the swinging frames, there-
fore, will be held by this hook until a cash key is depressed, but the pressing of
any key of a series will cause the pin ³ of said key to come in contact with the
beveled projections of the respective plates and thus move said plate about its
axis 1, which will in turn move the bell crank lever and release the segment.
The plate having the notched projections will move by gravity or by the aid of
a spring if desired so as to hook over the key and thus hold the key in a
depressed position.
On the shaft or axis 1, between the keyboard and the registering wheels, there
is placed a swinging arm h. This arm projects backwardly and downwardly
from the shaft 1, and is formed with a seat h' to support the swinging frames C¹ C
C3 C4, and from this point it extends downwardly and is formed at its lower end
with a foot 2, which rests normally in contact with a roller ³ on the back of
the drawer C. This swinging arm also projects upwardly from the shaft 1, as
shown at ht, and has at its upper end a spring-actuated pawl h³, which operates
in connection with the transferring mechanism of the register, which will be
hereinafter described. This swinging arm operates every time the drawer is
opened and may be assisted in its operation if desired by a spring 6, but so long
as the drawer is closed it will be seen that the arm h forms an obstruction to
the operation of the swinging frames C₁ C² etc., so that in order to operate one of
these frames it is necessary, first, to unlock the frame by pressing one of the
cash keys, and afterwards to release the frame by opening the drawer so as to
permit the arm h to move away from the frames and allow such of them as have
been released to move. From the former description it will be understood that

page_text: the opening of the drawer is accomplished by pressing any one of the depart-
ment keys e, and the pressing of such department key also operates one of the
latches which holds the pawl levers belonging to the registering wheels of that
particular department so that as the bars drop the pawl levers will be carried
with them and the pawl 63 will move along the registering wheels a number of
notches corresponding to the number of the key which has been depressed.
When the drawer is closed the arm h will be returned to its normal position as
the roller h³ of the drawer contacts with the lower end thereof. This will carry
the swinging frames back to their normal positions which carries with them the
pawls and thus moves the registering wheels a distance equal to the number of
notches which the pawls have been permitted to drop.
There is extending across the main frame above and below the line of the
department key stems e, two locking rods k and k¹. The key stems are notched
out at the top and bottom to receive these rods, as shown at and k³. The
rods themselves are also notched to receive the key stems, as shown at 5. It
will be seen from this construction that when the rods are turned so that the
notches are in line with the axis of the key, the key can be pushed through
the notches and operated, but when either of the rods is turned so that the
solid portion thereof comes within either of the notches or 3, then the key
is prevented from operation. Each of the keys e is further provided with
shoulders and 7, preferably having beveled ways leading up to the same, and
there is located above these keys a swinging bar, the arms of which are
journaled on a rod 4 so that the bar normally rests in contact with the shoulder k6,
and when the key stem is pressed inwardly it will rest in contact with the
shoulder. The bar normally stands with its solid portion turned into the
notch of the key stem e so that all the departments keys are normally locked.
The bar is connected to the hook-shaped arm of the bell-crank by a link klo
so that whenever one of the bell-cranks is moved by the depression of any cash
key it turns the rod k and thus releases the key stems e of the department keys.
There is an arm on the rod which is adapted to contact with a part of the
pivoted plate so that when the plate a is moved the rod is turned and the
turning of this rod again locks the key stems c. Inasmuch as the plate a imme-
diately returns to its normal position when a key is entirely depressed, this lock-
ing of the key stems e by the rod is only temporary and prevents the movement
of any of the department keys when a cash key is depressed only part way and
thus insures that the departments keys shall remained locked until a cash key
has been depressed to its limit and locked in this depressed position by the swing-
ing plates a6 and a. Whenever the depression of a cash key is followed by the
depression of a department key, then both of the rods and will be locked
against turning by the solid portion of the key stem e coming through the
notches in the respective rods. The arm will thus be held rigidly in contact
with the plates and prevent said plates from operating until the department key
has been returned to its normal position. It will thus be seen that the departments
keys are normally locked and are unlocked by the depression of a cash key.
The cash keys will all be locked immediately upon the operation of a department
key. When the rods and are released they are returned to their normal
positions by a spring 12, which is connected to projections on each of the rods
and tends to turn the rods to the normal position in which is in its locking
position and in its unlocking position.
The indicators, or targets, as they are sometimes called, for showing the
amounts registered, are located in the upper part of the casing and are adapted
to show through a glass-covered opening provided for this purpose. They are
preferably in the form of wheels, m, rotating on a rod or shaft 5, and are num-
bered corresponding to the numbers on the respective keys, there being one
indicator for each series of keys. The indicators are operated from the swinging
frames C¹ C etc., through the medium of pivoted armis m³, which are journaled.
on the shaft 1, and are each adapted to contact with a projection m³ on the

page_text: respective swinging frames. This projection m² is preferably provided with a
set-screw m³ to form a movable stop for readily adjusting the arm ml so that it
will occupy the proper relative position with the swinging frame to properly
display the number. There is attached to the arm m³ a rack m, which gears
with a pinion m³ on the indicator wheel m. There is also attached to the
indicator a ratchet-wheel m", the small teeth of which are adapted to be engaged
by a spring-pawl m², all of the pawls m² being secured to an oscillating rod m³:
This construction is such that the indicator wheel moves with the swinging frame
when it drops by the opening of the drawer, but the indicators are held by the
pawls m when the swinging frames are returned to their normal positions and
thus the indicators remain so as to display the amount last registered until a follow-
ing registration, when the indicators are released by the following described
mechanism. The rod m³ which carries the spring pawls m³ has at one end a
crank m³, (see Fig. 5), which is pivotally connected to a lever mo, which lever
is pivoted on the shaft 1. The lower end of the lever m¹0 is attached by a pivoted
slotted connection to a spring-supported arm m". This arm m has a projecting
finger m2, which normally rests in a notch m¹³ in one of the frame bars and beneath
a projecting finger f³ of the drawer lock f. The arm m" is attached to the frame
by two springs m¹ and m¹. The spring m¹5 tends to hold the finger m2 in the
notch while the spring m¹ tends to draw the arm m longitudinally when
the finger m2 is released from the notch m There is journaled on the shaft 1.
a swinging yoke C, which corresponds in shape to the swinging frames C¹ C³
CC. This yoke C also carries a weight and is called a gravity yoke" and
operates every time the drawer is opened. The projections which operate the
drawer lock also contact with the finger m2 so that every time the drawer is
opened the finger m¹² is raised from the notch m and the arm ml is moved longi-
tudinally, bringing the finger m2 under the projection f³, thus holding the drawer
lock out of its locking position and also moving the lever m10 so as to turn the
rod m8 and release the spring-pawls m² from contact with the ratchets me of the
indicator wheels, thus permitting the indicators to return to zero. As the drawer
opens the swinging yoke C contacts with the end of the arm m¹, and as the
drawer is closed the yoke engages with a projection or shoulder m¹ on said arm
and carries the arm back to its normal position, thus permitting the drawer lock
to assume its normally locking position and operating the spring pawls of the
indicators to cause them to rotate the indicators to any new position which they
may have assumed by reason of the depression of their cash keys.
To provide for indicating the character of the sale, a rotating indicator is placed
above the space occupied by the registering wheels. This is in the form of a
cylinder and has printed about its periphery words or signs corresponding to the
department keys. For operating this indicator to the proper position to show
the proper indication there is journaled on the main shaft 1 a series of arms n,
having downwardly-extending projections n¹, which rest on the outer or gravity
frame C. These arms also extend downwardly so as to engage a projection d³
on the latches D1 D2 D3. Each of the arms has a pin n², which engages a
link n, which operates a toothed segment n, meshing with a pinion on the
indicator cylinder. The end of the indicator has a ratchet wheel n and spring
pawl n, secured to the rotating rod ms to hold the indicator in its proper position
in the same manner as described for the amount indicators. The connection
between the toothed segment and the respective links n³ is formed by arm 28
on a rod or shaft to which the segment is connected. The links n³ are made i
of different lengths so that while all the arms n drop the same distance, they
will turn the indicators to different distances so as to bring the indicator corre-
sponding to the key depressed opposite the opening through which it displayed.
To provide for opening the drawer for making change or for other purposes
when no registration is to be made, an auxiliary key o is employed which operates
the latch D, the only function of which is to release the drawer lock and to
release the lever n corresponding to said key. With this key o the position of

page_text: the notches on the locking rods and is reversed so that the key is normally
unlocked, but is, locked whenever a cash key is depressed. It is possible there-
fore, to open the drawer without depressing a cash key or a department key, but
in so doing all the other department keys as well as the cash keys will be locked
and remain looked until the drawer is returned to its normal position.
To provide for unlocking the keys and allowing them to assume their normal
position after a registration is completed, there is pivoted at the rear of the
machine a trip arm P, the lower end of which is adapted to contact with the
roller has the drawer is closed. Connected to the trip arm P is a link p¹, which
in turn is connected through a slotted opening and pin p to a bell crank
arm 7. This bell crank arm is connected by a link to the arm of the
bar It also has a laterally projecting pin p, which engages with an exten-
sion a on each of the pivoted plates a. As the drawer is closed, therefore,
the roller, contacting with the trip arm ?, through the link 21, operates the
bell-crank lever p, and this in turn raises the bar to release the department
keys, after which a further movement of the bell crank lever raises the hooked
plates a so as to release the cash keys, all of the keys being returned to their
normal positions by springs employed for this purpose.
Inasmuch as the hooked
plates are locked by the pressing in of a department key, and the department
key is held in its inward or depressed position by the bar, it is necessary that
the releasing parts be so timed that the bar be raised from the shoulder
to allow the department key to return to its normal position prior to the time that
the plates a are moved to release the pins on the cash keys.
Means are provided by which not more than one of the special or department
keys can be depressed at the same time.. A simple method of accomplishing this
is by means of a flexible cord r, which is attached at each end to one of the
supporting rods 4, and alternately through stationary eyes on the rod and
similar eyes on the key stems. This flexible cord has just enough slack in it
to permit the movement of just one key, and if two keys are attempted to be
operated at the same time, neither one can be moved in sufficiently to perform
its function.
To prevent the overthrow of the registering wheels by a rapid movement or
sudden jerk of the drawer in closing, I provide a movable stop for the registering
pawls 63, which also forms a lock for the registering wheels. This is shown in
detail in Fig. 9 and consists of a bar 67, hinged at each end to a supporting
rod 6. This bar 67 extends across all the registering wheels at a point near
the limit of the throw of the respective pawl levers. An arm 8 extends down-
wardly from the bar 67 and is adapted to contact with the gravity yoke C³:
When the end of the arm 68 is relieved by the yoke or frame C5, this bar 6' moves
away from the pawls, but as the yoke or frame C contacts with the end of the arm 68,
the bar 67 is brought in the path of the pawls and thus forces said pawls firmly
against the registering wheels, at the same time forming a stop for the pawl and
also for the wheel. In order that this latter movement may be accomplished at
the proper time, which, is immediately after the registration is complete, and
also to provide for unlocking and releasing the pawl prior to the time the
swinging frames begin to move, I form on the arm ₁ an auxiliary pivoted arm
which contacts with the roller and is formed with an eccentric end 8, which
contacts with the gravity yoke C5 and imparts to said yoke an additional movement
after the arm h and swinging frames have been brought to their normal positions,
and it is this additional movement which produces the movement of the locking
bar 7, and at the same time the first movement in opening the drawer serves
to release the arm 68 and thus releases the pawls prior to the time that the arm h
begins to move with the opening of the drawer.
As before mentioned, each of the registering wheels is provided at certain
intervals, corresponding to the number of units of one denomination contained
in the next higher denomination, with projections b'. These projections are
adapted to operate pivoted latches 69, which engage pawls 610 on the wheel of the

page_text: next higher denomination so that the pawls will engage the teeth of the wheels.
Each of these pawls is attached to a pivoted link on the arm of a shaft 612,
and these respective shafts are adapted to be given an oscillatory movement by
projection thereon which contact with the spring-actuated pawl 5 on the sup-
porting arm and thus produce a movement of one notch in each registering
wheel whenever the registering wheel of the next lower denomination has been
moved a sufficient number of notches to make up a unit of the higher denomi-
nation. This particular mechanism, however, is described in the prior Patent 23920
of 1896 and need not be further described here.
It is obvious that the parts may be modified to suit any different denominations.
The constructions which are shown throughout most of the views are intended to
operate with the decimal system. Figs. 13 and 14 show the indicators and key-
board to suit the English system of money. When this system is used, instead
of having the projections on the registering wheels at intervals of ten, they
would be at suitable intervals corresponding to the number of units of one deno-
mination contained in the next higher denomination.
Means are provided by which whenever the drawer is opened an alarm is sounded
a gongs being shown for this purpose, but as the mechanism for operating it is
well known, it is not here described.
Reference has hereinbefore been made to the fact that when a special registra-
tion, or one which does not enter the total, is made, the totalizing mechanism
is prevented from operating, and the registering device for accomplishing such
special registration is shown at 13³. The latch D³ which releases the pawl
levers 65 for this register is connected to the swinging arm D, which, when the
latch is operated by the pressing of the department key of the special register,
is caused to engage in the notches 66 in the pawl levers 65 of the totalizing device,
which thus prevents the operation of said pawl levers and prevents the operation
of the totalizing register when the special register is thrown into operative position.
This construction is shown particularly in Figure 7 of the drawings. Any number
of these special registers may be employed and each constructed so as to operate
the swinging bar D when the latch which controls the registering devices is
moved. By this construction it will be seen that all of the registers on one side
of the totalizing device will operate in unison with the totalizing device, and the
amount registered thereon be added into the total, while those on the opposite
side will register independently of the totalizing device and during the time they
are being operated the totalizing device will be held out of operative position.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. In a cash register, the arrangement of the cash keys and the department or
special keys in connection with intermediate locking devices by which one set of
said keys is locked until a key of the other set is operated, substantially as
specified.
2. In connection with the above described locking devices, a movable cash
receptacle for unlocking and returning the parts to their normal positions, sub-
stantially as specified.
3. In a cash register, cash keys and special keys, an intermediate locking
device by which one set of keys is locked until a key of the other set is operated,
and a movable cash receptacle, and means for preventing the operation of the
mechanism through the agency of either set of keys after the cash receptacle is
opened, substantially as specified.
4. In a cash register, a series of cash keys and a series of registers, a common
intermediate operating device controlled by the cash keys for operating the ra
gisters, special keys for controlling the movement of said registers, and an inter-
mediate locking device for locking the special keys until a cash keys has been
operated, substantially as described,

page_text: 5. In a cash register, a series of registers, a series of cash keys common to all
of the registers, a series of special or departments keys, a rotating rod or shaft

7. The arrangement of the registering devices into groups or departments in
connection with a series of cash keys common to all the groups, and a series of
special keys, one for each group, and intermediate locking devices between the
respective sets of keys so arranged. that when a key of the first set is operated it
will unlock the keys of the second set, and a normally locked cash receptacle,
and means for unlocking the same when a key of the second set is operated,
substantially as described.
