Improvements in Indicating and Registering or Adding Machines.
I MATTHIAS RIEFF LONGACRE of No. North Thirteenth Street, Philadelphia
in the State of Pennsylvania United States of America Engraver do hereby declare
the nature of this Invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
This Invention consists of certain improvements in the construction of indicating
and registering or adding machines, more particularly machines adapted for indicating
the cash amounts of sales of merchandise either to the customer or the seller or both
and for totalizing or adding or registering the successive amounts.
The object of the Invention is to simplify the construction and operation of the
mechanism, to reduce the number of necessary parts and to construct and arrange the
details so that the machine will occupy less space than has been heretofore necessary
in machines for similar purposes.
The machine has among its principal elements, sets or series of numbered operating
keys for the several denominations of pounds, shillings and pence together with sliding
number plates or other moving indicators, impelled by springs and controlled by the
keys to show the numbers through openings in the case, when the keys are operated.
There is also a locking bar or bolt for each series of keys and means for restoring the
parts to their normal positions, and each moving indicator is retained in its normal
position at zero against the action of its impelling spring directly by one of the keys
themselves, and each moving indicator may be released by operating any one of the
keys of its set.
In the accompanying drawings-

In the present illustration of this invention, the moving indicator has been shown
as a sliding rack or number plate carrying upon its face figures for the corre-
sponding columns of pounds, shillings and pence, which figures are to show through
a suitable opening or openings in the case of the machine when one of the keys
of that set is operated. For the pence column, the indicator carries the numbers
from "0" to "11" while for the units columns of shillings the indicator carries
the numbers "0" to "9," and the indicator for the tens column of shillings only
carries the numbers "0" and "1." The indicator for each column of poun is carries
the numbers "0" "9." It is not, however, essential that these numbers should

page_text: be upon the sliding plates themselves, although it is preferred to arrange them in
that way.
The indicating numbers may be upon wheels to be operated by the
moving plates, or upon the plates as well as the wheels, as is the preferable plan,
so that the numbers upon one may be arranged to be seen by the salesman and the
numbers on the other seen by the customer. It is preferable to have in the machine
five of these moving indicators, two being provided for units and tens of pounds, two
for units and tens of shillings and one for the pence.
As the construction and operation of the several moving indicators, with their sets
of keys, are alike, with the exceptions hereinafter noted, it will suffice to describe
one set of these devices, or in other words, one section for one column of figures,
and afterwards speak of the exceptions. Figure 1 is a view of one of the set of keys
for the pounds columns.
A is the fixed casing or frame, which may or may not be combined with a sliding
drawer. In this frame are mounted, in this instance, several removable key bars A
representing successive denominations, as pounds, shillings and pence. Each bar A¹
carries a locking bar I and the numbered operating keys K which directly control the
position and movement of the sliding number plate. Each key bar, with its keys, and
locking bar, is complete in itself and independent of the other bars, and may be
removed and exchanged for a corresponding key bar at any time without interfering
with the others. The key bars for the pounds are interchangeable with each
other.
Each number plate B is shown in this instance as a flat plate having upon one edge,
for a portion of its length a rack into which gears a spur wheel mounted in an
arm on the frame and gearing into a pinion d fixed to the indicating wheel 1), which is
mounted to turn freely upon a shaft E in the casing. To the axis carrying the wheel d
is secured one end of a coiled spring F, while the other is connected to the inner
periphery of the spur wheel d¹ (Figure 1) and the parts are in the
present case shown
as so arranged that the spring tends to turn the wheel d¹ in the direction of the
arrow 1, Figure 1, so as to impel the number plate in the direction of the arrow 2
when released by the operation of one of the keys. I do not, however, wish to
restrict myself in this regard, as the number plate may be arranged to be impelled by
the spring in whichever direction convenience may dictate. The spring F, instead of
being within the spur wheel d¹ may be connected at one end to an arm on the frame
and at the other end to the hub of the indicating wheel D.
Each key bar carries a series of numbered operating keys K, passing vertically
through the frame of the bar and guided therein. In order to bring the key stems
close together, so that the necessary movement of the sliding plate can be shortened,
the manipulation of the keys facilitated and the size of the machine materially lessened
and its practical value correspondingly increased, the numbered head of each key is
placed out of line with its respective stem and each series of numbered heads is
arranged alternatively on one side or the other of the line of the key stems of that series,
as will be readily understood by reference to Figures 3 and 4.
In order to avoid possible confusion between the keys of one set and the keys of an
adjoining set, one series may have the numbers in black upon a white ground, while
the adjoining series has the numbers in white upon a black ground (Figure 4) or
they may be otherwise arranged so as to obtain similar contrasts between the
adjoining sets.
For convenience of manipulation of the keys, they may be arranged in banks one
above the other, as shown in Figure 1, and in the case illustrated the keys of the lower
numbers are on the upper banks, but this order of arrangement of the keys is not
essential. In Figure 1 there are shown three banks of keys with stems of different
lengths. The cover plate a of the machine is also preferably stepped.
It is preferable to make the stems for the keys of the rectangular section
illustrated in the drawing, and each key has upon its side a pin or projection
to engage with or act upon an incline or cam, which in this instance is in the
form of an inclined groove or notch j in the locking bar I. It is also preferred,
as will be seen on reference to Figures 3 and 6, to make this locking bar double,

page_text: so that the stems of the keys pass through it and in that case, I make the inclined
notches for the pins of the successive keys alternately on opposite sides of the
double locking bar, so that, for instance, the pin of the first key will find its notch
on one side of the locking bar, while the pin of the second key will find its notch on the
other side of the locking bar, as will be seen on reference to Figures 3 and 6.
Each key is sustained in the normal position illustrated in part in Figure 1, by
means of a yielding retainer & carried by the top plate or any fixed part of the key
bar, and having a bent end entering a notch n in the stem of the key. Whenever it
is desired, however, to depress any of the keys, this support & will yield and allow the

are maintained in their normal elevated positions, by means of these yielding supports,
their several pins or projections & will be out of the inclined notches but immediately
over the mouths of their several notches.
The result is that when one of the keys is depressed, its pink will enter the
corresponding inclined notch j and in doing so will positively move the locking bar I
in the direction of its arrow Figure 1. The remaining keys, except the retainer
key, are not affected but remain in their normal elevated positions in which they
are locked on the movement of the bar I, so that none of them can then be depressed
as will be understood on reference to the drawing. When the locking bar on the
restoration of the parts to their normal positions is returned in a direction opposite
to that pointed out by its arrow Figure 1 the depressed key will be raised (owing
to the riding of its pin up its inclined notch ) until its yielding support again
engages the notch n in the stem of the key. At the same time the return movement
of the locking bar brings the mouths of the inclinet notches back again into position
below the pins of the several keys, so that any one of the latter can then be depressed
to make another indication.
The term "locking bar" is used in this specification for convenience in a partially
descriptive sense, although it will be seen that the bar performs other functions besides
locking the keys.
Although more than one key may be used to act as a retainer for the sliding number
plate, to keep it at its normal position with the indicating figures showing zero, one
such key will be sufficient, and in the accompanying drawings the apparatus is shown
as constructed with but one retainer key. In this instance the first key to the right
in Figures 1 and 5, is illustrated as the retainer key, and it is made a little longer
than the others and bas at its lower end on one side a projection i, which when the
key is in its normal position engages with a notch in the edge of the sliding
number plate, as shown in Figure 5.
In combination with this key, there is formed on the upper side of the locking bar

depressed, the projection on the lower end of the stem will be disengaged from the

time the pin of the depressed key in entering the corresponding inclined notch in the
locking bar will move the latter over to lock the other keys in their elevated positions.
If it be one of the non-retainer keys which is depressed, the fifth key, for instance,
as illustrated, the locking bar I will be moved in the direction of its arrow by the
entrance of the pin into its inclined notch and consequently the reverse bevol j
will raise the retainer key out of engagement with the sliding number plate.
latter is then impelled forward by its spring F as before, until arrested by the fifth
key, which has been depressed into the pathway and stops it at the desired
position.
The
The above description applies to all the lines of keys except the one for pense and
the one for tens of shillings. It is evident that the only change in the pence line

page_text: consists in placing eleven keys 'in the set instead of nine and numbering the indicator
to correspond.
In the line representing the tens of shillings there is only one key used-the
number 1," as shown in Figure 4, as this figure is the only one employed in com-
bination with the nine units numbers to make a complete indication of the shillings
column. The locking bar and other parts for this column of tens of shillings may be
the same as represented in Figure 1, except that only one inclined notch is required
for the one key. The indicator for tens of shillings consequently only shows the
figure one when released by its one key and is only marked with this figure together
with "0" or zero, which it normally shows with the rest, and its total movement is
therefore from zero to one and back to zero.
By preference two sets of openings are provided to show the numbers on the
moving indicators, one of these openings a being for the operator and the other a²
for the customer. Both sets of numbers in such case may be upon the sliding
number plate but facing in opposite directions, as will be readily understood and in
such case the operator will have to read his figures from right to left or backwards
so that the customer on the other side of the machine can read from left to right.
Instead of having the second set of numbers upon the number plate to be
exhibited to the customer it is however in most cases desirable to put such numbers
upon the periphery of the wheel D carrying a pinion d geared to the spur wheel d',
so that the numbers could be conveniently seen through an opening in the case.
It will be understood that the first set of numbers upon the sliding number plates may
also be dispensed with and the numbers upon the indicating wheels D only be employed.
To restore the indicating parts to their normal positions there is provided a
sliding frame Q, which may be attached to and combined with a cash drawer Q',
as shown in Figure 2, or be simply provided with a handle as shown in Figure 7.
In either case, this frame slides in suitable horizontal guide grooves or on suitable
horizontal guide ways upon the fixed frame A and is provided with a cross bar X,
which has as many upright pins (Figures 2 and 6), as there are sliding number
plates. On the under side of each number plate is a projection a¹ at a suitable point
in the path of the corresponding pin a. As therefore the cash drawer or slide Q is
pushed in the direction of its arrow, Figure 7, the pins on the cross bar X will
come into contact with the projections on the sliding number plates and thus return
them to their normal positions. Just before each sliding number plate reaches the
end of this, its inward movement, the pin a will come into contact also with a
projection on the end of the locking bar I as shown in Figure 6, and restore the bar
also to its normal position, so that the depressed key K may be raised again and
the other keys which had been locked up, may then have their pins over the
notches again ready for the next indication.
With the above described mechanism, forming in itself a complete indicating
machine, there may be combined any suitable totalizing or registering or adding
mechanism. But to make a complete indicating and adding or registering machine,
it is preferred to combine with the above described mechanism the totalizing devices
illustrated in Figures 8, 9 and 10.
A series of registering dials or adding wheels U (U1, U2, etc.) are provided for
pounds shillings and pence, (Figure 10) and these wheels are mounted upon the
same shaft E which carries the indicating wheels D D &c., and numbered to
correspond. Each indicating wheel is thus provided with a corresponding adding
wheel-for example an adding wheel U for pence, one each (U' and U2) for units
and tens of shillings, and one each (U³ and U*) for units and tens of pounds.
These various indicating and adding wheels are preferably arranged as
shown in the drawings but they may be arranged on the shaft in any
order in which the motion can be transmitted from the indicating wheel to its
corresponding adding wheel. Each adding wheel with the exception of the adding
wheel for pence has laterally projecting pins a corresponding in number with the
number of the figures on its periphery.
The connection between each indicating wheel and its adjoining or corresponding

page_text: wheel 15 through the medium of a pawl & on the indicating wheel engaging
with the ratchet wheel T formed on or attached to the adding wheel (Figures 8 and 10)
and so arranged that the wheel D in making its indication, after being released by
the operation of the key, turns in the direction of the arrows 1 Figure S, and its pawl
5 runs free on the ratchet T without moving the adding wheel, but on returning the
indicating wheel and number plate to zero as described, the indicating wheel D
moves in the direction of the arrow 2, and by means of its pawl then engaging with
the ratchet T, carries with it its corresponding adding wheel an equal distance, or
the same number of fractional parts of a revolution, thus transferring the indicated
figure to the adding wheel.
For this reason the figures on the adding wheel run in the opposite direction
from those on the corresponding indicating wheel, as seen on referenec to Figure 10.
In this figure, U is the adding wheel for the pence indicating wheel D, while U
and U2 are the adding wheels for the units and tens shilling indicators D1 and D'
respectively. Similarly the adding wheel U belongs to the units pound indicator Da
while the last adding wheel shown (U) belongs to the tens pounds indicator D*.
In order to transmit motion from one adding wheel U for instance, to the next
higher adding wheel U for the purpose of carrying, as for example when the wheel U
for the lower column has made a complete, revolution, there are combined with the
adding wheels, devices which, in this instance, are mounted in part upon a
plate 7, moved by or attached to the sliding frame Q, and in part on the fixed frame.
sliding
The fixed part of these devices is operated upon by the adding wheel U, when a
carrying is to be done, and places the part on the sliding plate g' in position to operate
on the next higher adding wheel U¹.
Each adding wheel U, (U' &c.) has upon it a projecting pin (Figures 8 and 10) at
such a point that when the zero mark upon the wheel is uppermost the said pin will
be nearing its lowest position, and will come in contact with an arm m (see dotted
lines in Figure 6) on a pivotted switch gate or cam M, which is carried on a longi-
tudinal bar R on the fixed frame, Figure 12.
This description applies to all the adding wheels but the one U2 for the tens of
shillings (Figure 10). We have seen that the indicator D³ for tens of shillings has
only a limited movement of one space at a time, and this movement is communicated
to its corresponding adding wheel U by the pawl connection as described. The
adding wheel U for tens of shillings, in common with all the other adding wheels has
necessarily a movement in only one direction. This adding wheel is divided into ten
spaces and these ten spaces are marked alternately "0" and "1" to correspond with
he indicating wheel D with which it is connected by the pawl and ratchet.
space in this adding wheel is therefore the equivalent of ten shillings or one half a
Each
ound and it consequently follows, that this adding-wheel U2 should move its next
igher adding wheel U³ (or the one for units of pounds) every second space instead
every full revolution as the others do.
This is accomplished by providing this adding wheel with five pins u properly
laced instead of one, so that the result is that every time this adding wheel is moved
show a cipher it has set the carrying device to carry one to the adding wheel U³
epresenting units of pounds.
The switch gate or cam M of each of the carrying devices consists of a switch point
votted at 13 in a notch in the side of the bar R and of such a shape that when the
vitch is closed the bar is continuous, but when the switch is turned to the open
osition, an inclined notch or groove is left in the side of the bar, as shown in
igures 8 and 9. On the back of the switch is an arm m which when the switch is
osed lies in the path of the pin u on the adding wheels U (U &c). The rotation of
e wheel U in the direction of the arrow 2, Figure 8, results in the depression of
e arm m by the pin and the opening of the gate or cam from the position
own by dotted lines in Figure 8 to that shown by full lines in Figures 8 and 9.
The switch gate
is held in either of its extreme positions, that is open or closed, by
ans of a spring n² with a V-shaped end pressing upon a pin n¹ carried by the arm m
the switch gate or cam (Figure 8).

page_text: Secured diagonally across the bottom plate 7' (Figure 11) which is operated by or
attached to the sliding frame Q or cash drawer are the movable parts M' of the
carrying devices. These movable parts M' (Figure 9) have each two pieces fitted
loosely on the same support m³, the part m' extending to the rear and the part M²
forward of this support. The part m is so constructed that normally it rests on the 5
tail piece or extension m of the part M2 and is provided with a pin m³ extending
laterally over and riding on the fixed bar R, as illustrated in Figure 9. The part M²
is retained in its normal position shown in Figure 9 and by full lines in Figure 8
by the spring m² pressing on the underside of its tail-piece m.
With all the
parts of the carrier devices in their normal positions the pin m³ of part m² rides 1
without obstruction over the fixed bar R, allowing the sliding frame or cash drawer
to be moved freely in or out.
When the pin on the adding wheel U (U' &c.) comes into contact with the
arm m of the switch gate or cam M, and opens the switch as illustrated in
Figure 8, the pin m³ of the part m will strike the upwardly projecting end of 1
the switch gate or cam as the cash drawer or the sliding frame is pulled out, and
carry the part m' to the underside of the bar. The part in¹ is now pressed down on
the tail-piece m and lifts the end or nose of the part M2 against the tension of the
spring in upwards into the path of the pins u on the adding wheel U and as the
drawer is pulled further outward or toward the operator the part M² carries this
adding wheel forward to the extent of one number or one tenth of a revolution.
As the laterally projecting pin m³ on the tail-piece m¹ (Figure 9) passes to the
lower side of the bar It in the above described movement, it closes the switch gate or
cam M by acting upon its underside, and thereby lifts the arm m again into the path

under the control of the spring n until the adding wheel which caused its operation
bas completed another revolution.
As the drawer is pulled still further out the pin m³ on the tail piece m¹ passes
up through the notch y' (Figure 8) to the upper side of the bar R, while the end
of the nose or lever M released from the control of the tail-piece m³, drops down
under the action of the spring m² (Figure 8), to its normal position.
The laterally projecting pin on the tail-piece m' will, on the return movement of
the drawer, travel freely over the upper side of the bar R, and over the switch
gate M, open as well as closed, for the tail-piece m' has sufficient independent
motion to allow the projecting pin m³ to ride easily over the projection end of
the open switch gate without closing it, should it find the switch gate open when
it reaches it on its return movement.
There is also formed on the under side of the bar R which carries the switch
into which the tail-piece m¹ will enter (Figure 8) should

the operator try to push back the sliding frame or drawer after the pin on the
tail-piece m has passed to the underside of the bar R and closed the switch gat
as described. This compels the operator to pull the drawer fully out and complet

every carrying which the carrying device has been set to perform as described.
The foregoing description applies equally well to the devices for "
from the adding wheel U₁ for the units of shillings to, the adding wheel U fo
the tens of shillings, and from the wheel U2 to the adding wheel U³ for th
pounds and so on, the shapes only of the arms me and noses M² being varied a
location requires, as will be understood on reference to Figure 12. Thus as th
succeeding cash sales are added up or registered, the pence, shillings or poun
are transmitted from one adding wheel to the next higher one.
In order to prevent any failure of the proper transmission of movement fro
one adding wheel to the next higher one, such as might occur where two or mo
set together, the parts M1 of 1
of the parts M of the carrying devices were
several carrying devices are arranged out of line with the axis of the shaft, (
shown in the diagram Figure 11) so that no two adding wheels can be operat
by them at the same time, and in this manner a means is provided for transmitti
the necessary motion or "carrying;" successively from the adding wheel of c

page_text: denomination to the adding wheel of the next higher denomination, through the
entire series of adding wheels.
From the foregoing description, it will be seen that when the parts have once
been set to their normal positions ready for an indication but before a key has
been depressed. the cash drawer Q₁, if that is used, can be freely moved in and
out without affecting the indicating mechanism and consequently also without
affecting the adding mechanism as the latter is first operated from the indicating
mechanism. On the other hand, as soon as an indication has been made by
depressing one or more of the keys, the cash drawer comes into play as an operative
part of the combination to restore the parts to their normal positions and to transmit
motion to the adding or registering mechanism.
The adding wheels may be returned to zero in the following simple manner
after the reading of the day's work shown on the adding wheels has been taken.
The keys are operated to indicate an amount which if added to the reading on
the adding wheels would make one hundred pounds. For example, if the adding
wheels stand at seventy six pounds, thirteen shillings and sixpence (£76 13: 6),
the operator will touch keys to indicate twenty three pounds, six shillings and. six
pence (£23: 66), when the usual manipulations will totalize ciphers. Or, if
preferred, the adding wheels may all be individually returned to zero by hand.
:
It will be also seen from the foregoing description that in this machine the keys
can be operated without reference to their serial order or a key in any one series
can be operated simultaneously with a key in any one or all the other series without
disturbing the transferring of the figure from the indicator to its corresponding
adding wheel or the carrying in proper succession from one adding wheel to the
next higher through the entire series.
