Improvements in and connected with Apparatus for Recording
Money Transactions or Financial Accounting.
We HENRY GIBSON O'NEILL of No. 1055 Third Street in the City of Louisville
and JOHN GILMOUR of Owensboro, both in the County of Jefferson and State of
Kentucky, one of the United States of America, Gentlemen do hereby declare the
nature of our invention to be as follows:-
:-
The object of the invention is to provide for financial transactions, receipts or dis-
bursements, a recording instrument, adapted to facilitate money transactions through
an accurate uniform and safe mechanical system of financial accounting aided by
printing recording devices.
In carrying out this invention we have provided, in conjunction with a series of
movable indicators respectively marked with the nine digits and the cypher, a single
key for each digit indicator, operating mechanism common to the nine digit keys, and
a series of notation keys guarding and governing the operation of the digit keys and
indicators, whereby the movable digit indicators can be operated only after the proper
notation key has been moved to effect the engagement of its indicator with the
operating mechanism of the digit keys.
We have also provided recording type wheels arranged in notation series and
operated independently by the digit keys and gear-turning mechanism, normally
disengaged from said type wheels, but set in operative connection therewith by a
series of notation shifting keys, governing the engagement of the type-wheels and
guarding the action of the digit keys and their gear turning mechanism.
We have also provided, in conjunction with the recording type wheels arranged
in notation series, and the operating mechanism normally disengaged therefrom, but
set in engagement therewith by means of notation-shifting keys, certain consecutively
numbering wheels and turning pawls therefor, whereby at each movement of the
printing platen, the transaction being recorded is numbered.
We have also provided in connection with a printing platen, the type wheels, and
their operating mechanism, a stop device limiting the action of each digit key, so
that when the type wheels are set to record a transaction the mechanism is prevented
from further effective working until the platen is operated to print off the transaction
and make record thereof.
And we have provided in conjunction with the recording and indicating
mechanism, an adding attachment adapted to sum up the values of the transactions
recorded.
We have provided in combination with a series of recording devices indicators or
adding wheels, a series of notation keys adapted to set their respective recording
devices, indicators or adding wheels and a single series of digit keys operating through
gear-turning mechanism common to said digit keys, to move any one of the recording
devices, indicators or adding wheels, when set.
A suitable encasement is provided to enclose the mechanism, and prevent tampering
therewith, said encasement being duly guarded by means of a lock. In constructing
the machine, a suitable framework is provided with the bearings for the operative
parts. There is also provided a series of recording type wheels having gear teeth; a
vibrating platen or press; numbering wheels in line with the recording type wheels;
digit keys, having finger pieces and levers, and notation keys also having finger pieces
and levers.
The operating shaft of the printing platen is provided with a connection to operate.
a rock shaft which actuates the pawls of the numbering wheels.
Clasmananding in number to the recording type wheels and notation keys, arø

page_text: parallel rock-shafts, respectively connected to the notation key levers, and respectively
provided with arms and rock-carriers, which support a series of adjustable racks, one
for each rock shaft. These rock shafts are operated by their respective notation
keys, each to raise or set its rack in gear with a pinion on a shaft, which is turned by
the main gear wheel when one of the digit keys is pressed to move the main gear
wheel.
The recording type wheels are normally engaged with the racks and the mechanism
operated by the notation keys, and are normally disengaged from the gear-turning
mechanism operated by the digit keys. When, however, one of the notation keys is
pressed the corresponding rack is set or shifted to engage the pinion of the gear-
turning mechanism; and as each digit key operates to turn the main gear wheel
through an are corresponding to the digit of said key, the pinion is correspondingly
rotated, and the rack in engagement therewith reciprocated, turning the type wheel
to bring the proper figure thereon to the front or printing position.
In connection with the platen shaft, is provided rack returning mechanism con-
sisting usually of segment gearing, a returning pinion provided with a ratchet head
and pawl, a reversing pinion and its pawl. When the platen shaft is turned to move
the platen toward the type wheels to effect the printing, the reversing pinion turns
freely away from its pawl but when the platen moves back or away from the type
wheels the reversing pinion becoming locked to the returning pinion the latter is
rotated and moves the rack or racks back to normal position.
The racks are of sufficient length to rotate their type wheels once around, and when
they have made their full movement a stop prevents further motion in the forward
direction. Before the type wheels can be again operated the platen must be worked
and the racks returned to normal position, this being indicated usually by means of a
bell or other alarm.
In connection with the shafts on which the ribbon rollers are mounted is arranged
a shifting shaft having crown wheels and a ratchet which is operated by a pawl con-
nected to an arm of the platen operating shaft. The shifting shaft is adjustable
end wise in either direction, so that it can be made to engage first one roller-carrying
shaft and then the other.
The numbering wheels are provided with ratchets having deep tenth notches to
allow the carrying pawls to engage.
The gear-turning mechanism operated by the digit keys comprises compound ball
levers, and pawls and stops in connection therewith, whereby, when a notation key is
pressed, any one of the digit keys can be operated to rotate the main gear wheel
through an are corresponding in length to the number of units of the digit whose
key is pressed. The gear-turning mechanism is returned to normal position by spring
action.
Each digit key lever is provided with a stop projection of proper height to engage
a stop bail when the latter is revolved down by the operation of said digit key lever,
in engagement with a bail lever, moving the upper part of said bail lever forward,
and throwing the lower part of an arm thereof backward and moving its pawl to
engage and rotate the main wheel.
Bearing studs are provided in line with the prolongation of the axis of the main-
gear wheel, and on these studs are pivoted the arms of the stop bail. To the lower
ends of these arms are pivoted the lower ends of the arms of the bail lever, said arms
being held back against extensions of the digit key levers by a spring.
Connected to the bail lever is a stop pawl, which, when said bail lever commences
its movement releases the main wheel. As said bail lever continues its movement
under the action of the digit key lever, its arms engage the bearing studs which
become fulcrums therefor, and cause said bail lever to cant forward, revolving the
stop bail downward and to engage the stop projection of the key lever, and moving
the actuating pawl to turn the main gear wheel.
Before the main gear wheel can be turned, its engaged pinion must be relieved from
a locking pawl of the notation shifting mechanism; and to this end said locking pawl
is connected to a lever arm of a rock shaft, which also carries a pressure plate which

page_text: extends under the feet of the digit keys. The locking pawl is provided with a
spring acting to draw it out of engagement with said pinion when free so to do.
Said lever arm however engages a bearing of a bail lever which extends lengthwise
under the notation key levers, and which is normally held upward by a spring, and
holds sait locking pawl in engagement with the ratchet of said pinion. When any
one of the notation keys is depressed, the bail lever under the notation key levers is
also depressed and releases the lever arm allowing the spring of the locking pawl to
instantly act and release the pinion. The action of the digit keys and gear-turning
mechanism is therefore guarded by, and dependent on the oporation of the notation
keys.
These notation keys are arranged in notation series, the first key on the right
designating the unit's place or type wheel the next key, in the decimal system which
is employed in explaining this invention, the ten's placo or type wheel, the next, the
hundred's place or type wheel, and so on throughout the series, which may be carried
to seven or eight places. And usually the pressure heads or finger pieces of the
notation keys are coloured to correspond with the rulings of a ledger or account
book. For the decimal system of coinage the first two notation keys may have
white heads, the next three red, and the others blue; while for the system in use in
Great Britain, the two keys succeeding those bearing the white heads should be
provided with red finger pieces. By thus colouring the keys the operator is enabled
to act with certainty and rapidity in pressing the proper notation key for the figure
to be recorded.
As the type wheels are somewhat hidden under the ribbon, indicating devices are
provided to show what has been set up by the type wheels. To this end the shaft of
the pinion which engages the main gear wheel may be provided with a series of
pinions corresponding in number to the type wheels. Indicator wheels having lateral
pinions are pivoted to levers arranged in series and journalled on a shaft. These
levers are provided with resetting segments engaging the lateral pinions, and with cam-
like edges or inclines at their lower ends to engage lateral studs of the notation
levers when the latter are depressed, this action causing the said levers to vibrate
sufficiently to bring the pinions of the indicator wheels in engagement with the
pinions of the shaft which is in connection with the main gear wheel. Therefore,
when the gear-turning mechanism is put in action by any digit key, it will not only
rotate the type wheel corresponding to the notation key actuated, but will also rotato
the corresponding indicator wheel bringing the proper figure thereof to the sight slot
of the encasement.
The shaft upon which the indicator levers are pivoted is provided with resetting
arms, and to said shaft is secured a segment gear engaging a segment lever pivoted
to the frame and having its rear arms slotted to engage a crank arm of the rock
shaft of the printing platen. When the indicator wheel is rotated by the action of
the digit key, its resetting segment is turned back toward one of the resetting arms,
and similar movements of like parts occur for the other indicator wheels when
operated, for all the figures expressing a financial transaction. After these move-
ments, it is in order to print off the transaction upon the recording paper under the
platen and in contact with the printing ribbon by moving the platen toward the type
wheels. During this operation the platen shaft actuates the segment lever and causes
the resetting arms to engage lateral pins of the segments of the indicator levers and
to rotate said segments forward to normal position, this action also bringing the
indicator wheels back to their first position so that they show zero at the sight slot
of the encasement. By the backward or reverse movement of the platen the resetting
arms are carried back to their normal position.
An adding attachment to this recording machine may be provided when desired.
For this purpose a series of adding digit wheels are provided with shifting pinions,
which, when the notation keys are operated are brought into engagement with the
pinions of a slide shaft in engagement with the main gear-wheel, in order that when
the main gear wheel is turned by operating a digit key, the proper digit wheel or the
adding attachment will be turned. These adding digit wheels are provided with

page_text: carrying devices and the attachment will serve to show at a sight slot of the case the
sum of the values of the transactions recorded. The adding attachment is provided
with a resetting lever adapted to actuate all the notation Keys simultaneously, and
with check devices for the adding wheels which have mutilated gear portions adapted
to engage the pinions of the slide shaft when moved by said resetting lever to
resetting position. When the resetting lever is depressed, the movement of one
of the digit keys will cause the entire series of adding wheels to rotate until stopped
by the check devices each with zero showing at the sight slot of the case.
The mechanism is designed to be enclosed in a secure encasement having an
opening where the platen works, of sufficient size to permit the entry of a recording
strip, or the insertion of cheques or drafts. The sight slots are glazed and the cover
or door of the encasement is provided with a secure lock the key whereof should be
in the possession of the person for whose information and security the machine is
operated.
By means of these machines financial papers may be numbered and stamped with
their values, and a regular record may be kept showing each transaction by its valuo
and consecutive number.

Improvements in and connected with Apparatus for Recording
Money Transactions or Financial Accounting.
We, HENRY GIBSON O'NEILL, of No. 1055 3rd Street, in the City of Louisville,
and JOHN GILMOUR, of Owensborough, both in the County of Jefferson and State of
Kentucky, in one of the United States of America, Gentlemen, 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:-
The object of the invention is to provide, for financial transactions, receipts or
discounts, a recording instrument wherein the type wheels, arranged in notation
series are operated independently by digit keys, and gear-turning mechanism,
normally disengaged from the gear in connection with said type wheels, but set in
operative connection therewith by a series of notation shifting keys, governing the
engagement of the type-wheel gear and guarding the action of the digit keys and
their gear-turning mechanism; the invention further consists in providing in con-
nection with the recording type wheels arranged in notation series, the type wheel
gear and the operating mechanism normally disengaged therefrom but set in engage-
ment therewith by means of notation shifting keys, the consecutively-numbering
wheels and turning pawls operated at each movement of the printing platen; the
invention further consists in providing a stop device in connection with the mechanism
of the printing platen, limiting the actions of each digit key, so that when the type-
wheels are set to record a transaction, the mechanism is prevented from further
effective working until the platen is operated to print off the transaction, reset the
type wheel and make the record; the invention also consists in providing an
indicator attachment for the recorder wherein the indicator wheels are operated
in like manner to the type wheels and are similarly reset when the printing platen
is operated.
And the invention further consists in other novel devices and combinations, as
hereinafter set forth.

In the accompanying drawings, the letters A, A, designate the recording type
wheels; B the platen or press; C, C, the numbering wheels in line with the recording
type wheels; D, D, the digit keys including their finger pieces d, and levers d
and E, E, the notation keys, also including their finger pieces e, and levers e¹.
Z indicates framework.
F is the operating shaft of the printing platen, having a lever F', and connection F",
to operate the pawl-moving shaft f, which actuates the pawls c, c, of the numbering
wheels C, C:
G, G, are rock-shafts thereof which in practice correspond in number to the type.
wheels, and notation keys, though in the present instance being shown one less in
number than said keys, and said rock-shafts are respectively connected to the notation
key levers, as indicated at a, and are operated thereby when the notation keys are
pressed.
These rock-shafts are provided with arms G¹ and rack-carriers G", which support the
racks A', and, when said rock-shafts are turned, raise or set said racks in gear with
the pinion gear g' of the pinion shaft g, which is operated by the main gear wheel H,
when the digit keys D are pressed.
The type wheels are normally engaged with the setting racks and the mechanism
operated by the notation keys, and are disengaged from the gear-turning mechanism
operated by the digit keys. When, however, one of the notation keys is pressed, the
corresponding rack is set or shifted to engage the pinion g', of the gear-turning
mechanism. As each digit key operates to turn the main wheel H, through an are
corresponding to the digit of said key, the pinion g' is correspondingly rotated and
the rack in engagement therewith reciprocated turning the type wheel to bring the
proper figure thereon to the front or printing position.
In connection with the shaft of the platen B, is the rack returning mechanism
which may consist of the segmental gear gl, on said shaft meshing with a corre-
sponding gear on a segmental rack, suitably supported in position, à returning
pinion K on a shaft K', gearing with the teeth of said rack, a ratchet head k, on said
returning pinion, engaged by a pawl, and the reversing pinion & arranged on
the ratchet head k, engaged by a pawl kl.
When the shaft F is turned to depress the platen toward the type wheels to effect
the printing, the segment gear g" moves backward, turning the reversing pinion
freely away from its pawl. When, however, the movement of the platen operating
shaft is reversed, the segment gear is moved forward, and the reversing pinion k
engaging the rack A', becoming locked by its ratchet and pawl to the ratchet head of
the returning pinion K, the latter is rotated and moves the rack or racks A' back to
normal position.
The racks A' are of sufficient length to rotate their respective type wheels once
around, and when they have received their full movement, a stop B' prevents further
motion in the forward direction. Before the type wheels can be again operated the
platen must be worked and the rack or racks A returned to normal position.
A bell or alarm Fx is usually employed in connection with the platen moving
mechanism to indicate when the platen has been moved back from the type wheels,
and when the racks have been returned to their first position, through the

page_text: striking of the hammer of said bell by a projection F×× on the inner side of the
segmental gear g".
The numbering wheels C, C, are provided respectively with ratchets c, cl, each
having a deep tenth notch ex to allow for the engagement therewith of the pawls c.
The pawls c, c, are rigidly connected and held in their operative position by the coiled
spring c², as seen in Figure 11..
L, L, are the printing ribbon rollers, carrying the ribbon . The rollers are
mounted on shafts turning in bearings of the frame, and provided with pinions,
alternately engaging the driving crown wheels I, I, of the shifting shaft L", which
is provided with a ratchet 1, operated by a pawl connected to the arm F", which
extends from the platen operating shaft . The shaft L" is adjustable endwise so
that either of its crown wheels can be brought into engagement. By this means the
ribbon may be moved in one direction until it is nearly unwound from one roller, and
then the motion may be reversed in order to unwind it from the other roller back
upon the first. The shaft I. carries the paper feeding roller S.
The gear turning mechanism operated by the digit keys, comprises, in the con-
struction illustrated, the compound-bail-lever devices I, J and the pawls and stops in
connection therewith, whereby, when a notation key is pressed, any one of the digit
keys can be operated to rotate the main gear wheel H, through an are corresponding
in length to the number of units of the digit whose key is pressed, by means of the
varying arcuate upper edge of the stop projection of the respective key lever, fully
hereinafter referred to. In the instrument illustrated the carrying devices are
arranged in accordance with the decimal system; but this may be varied to suit other
systems of coinage.
Each digit key lever d¹ is provided with a stop projection d, of proper height and
segmental area to engage the stop bail J, when the stop projection is carried down by
the operation of the ligit key lever the required extent, moving the upper part of the
bail lever I forward, and at the same time throwing the lower part of the arm of the
said lever next the main wheel H backward, and moving its pawl I¹ to engage and
rotate the main wheel.
The bearing stud m, forms a prolongation of the axis of the main wheel H, and
opposite thereto on the frame is the bearing stud m³, and upon these bearing studs are
pivoted the arms of the stop bail J. To the lower ends of these arms are pivoted the
lower ends of the arm I*, of the bail lever I, said arms I* resting a little in rear of
the studs m, m when the bail lever is in retracted position, being held back against
the extension D' of the digit key levers by the spring D".
His a stop pawl, which is by means of a connection jointed to the bail lever I,
so that when said lever commences its movement said stop pawl is released from the
teeth of the main wheel. As said bail lever continues to move forward pressed by the
digit key lever, its arms engage the studs m, m', which become fulcrums therefor,
and cause said bail lever to cant forward and to move the stop bail J, downward to
engage the stop projection d" of the key lever, and moving the actuating pawl I to
turn the main wheel.
Before, however, the main wheel can be turned by the devices described it
must be released from the action of the locking pawl E of the notation shifting
mechanism, said pawl engaging the ratchet e¹¹ of the pinion P, which engages the
main wheel.
The locking pawl E' is connected by a bar Ex to a lever arm b, of a rock-shaft M,
which also carries a pressure plate B*, which extends under the feet 1, of the digit
keys; and said locking pawl E' is normally held out of engagement with the ratchet
of the pinion P by a spring, as at El, while a supplemental pawl ex engages a
ratchet exx, on the side of the ratchet e¹¹ to prevent a reactionary movement of said
ratchet. The outer end of the lever arm b, engages a bearing as at 6, of a bail
lever M, which extends lengthwise under the notation key levers in position to be
pressed downward thereby when the notation keys are actuated. This bail lever M
is normally held upward by a spring M", which connects with the pawl ex and lever

page_text: arm b, and by engagement with the lever arm 6 holds the locking pawl E' in engage-
ment with the ratchet e" of the pinion P.
When any one of the notation keys is depressed, the bail lever M is also depressed,
and releases the lever arm b, allowing the spring E" to instantly act and release the
pinion P. It is therefore apparent that the action of the digit keys and gear-turning
mechanism is guarded by and dependent on the operation of the notation keys, since
by the depression of any one of which it will have been noticed from the foregoing
that the pinion P is free to be turned by the wheel H simultaneously with the
actuation of the digit gear-turning mechanism, which latter operation is effected by
the bail lever devices I, J, as above pointed out.
These notation keys are arranged in notation series, the first key on the right
designating the unit place or type wheel; the next in the decimal system the tens or
type wheel the next, the hundred's place or type wheel, and so on throughout the
series, which may be easily carried to seven or eight places.
Usually the pressure heads or finger pieces of the notation keys are coloured to
correspond with the ruling of a ledger or account book, the first two heads being
white, the next three red and the others blue. The object of thus designating the
keys is to enable the operator to act with certainty and rapidity in pressing the proper
notation key for the figure to be recorded.
As the type wheels are somewhat hidden under the ribbon and by the paper upon
which the record is made, it is usual to provide in connection with this recorder,
indicating devices to show what has been set up by the type wheels, and to this end
the shaft p, of the pinion P, is extended, and provided with a series of pinions P¹,
corresponding in number to the type wheels.
N, N, represent the indicator wheels, which are provided with lateral pinions n, and
are pivoted to the upper ends of levers 'N', which are pivoted to the shaft N and are
also provided with the resetting segment gears n', engaging the pinions n and having
the lateral studs n", normally engaging the front stops v.
The levers are provided with cam edges or inclines q at their lower ends to
engage lateral studs q' of the notation levers e¹, when the fatter are depressed, this
action causing the levers N¹ to vibrate backward slightly or sufficiently to bring the.
pinions of the indicator wheels in engagement with the pinions P of the shaft P.
Thence when any notation key is operated, its lever N' is also moved to bring its
indicator wheel to engagement position, in order that when the gear-turning
mechanism is put in action by any digit key, it will not only rotate the type wheel
corresponding to the notation key, but will also rotate the indicator wheel, bringing
the proper figure thereof to the sight slot Y, of the case.
The shaft N is provided with the resetting arms which normally extend rearward,
and to said shaft N at its end is secured the segment gear R', engaging the segment
lover R which is pivoted to the frame, and slotted in its rear arm to engage a stud of
a crank arm of the rock shaft F of the printing platen. When the notation key is
depressed bringing the indicator wheel to engagement position, and a digit key is
operated to rotate the type wheel, the indicator wheel is also rotated, and the resetting
segment is turned back toward one of the resetting arms R. Similar actions of
corresponding parts occur on operating the notation keys and digit keys to set the
type wheels and indicator wheels for all the figures of a transaction, and after this has
been done it is in order to print off the transaction upon the paper under the platen
and upon the printing ribbon. Upon moving the platen lever to depress the platen
toward the type wheels, the rock-shaft F is operated, actuating the segment lever R",
and turning the shaft N11 forward with its resetting arms which engage the lateral
pins of the segments n', and rotate said segments forward to normal position, this
action bringing the indicator wheels also back to their first position so that they show
zero at the sight slot of the case.
Upon moving the platen lever to the rear, and rotating its rock-shaft F back, the
segment lever R is again actuated, rotating, the shaft N and its resetting arms R
back to their normal position.

page_text: to zero.
After each transaction is printed the type wheels and indicator wheels are set back
In operation, the figures of the required number or amount it is desired to
record being given, the corresponding notation and digit keys are operated in their
order, the actuated rock-shaft G bringing into requisition the required racks A',
through which the said notation keys are put into co-operative relation with the
platen. Simultaneously with the action of said digit keys the bar B* is depressed
therefor, pulling upon the lever arm b, which will disengage the pawl E¹ from the
ratchet e, thus unlocking the shaft p, which through its pinion P is thus rendered
capable of rotation by the wheel H, the pawl H', also at the same time being dis-
engaged from the wheel H, and the stop projection or projections d" of the digit key
levers caused to pass at their upper arcuate edges under the stop bail J during their
initial movement. In the meantime the upper end of the bail lever I is canted
forward or downward by the fulcruming of said lever upon studs m. m³, thus throwing
its lower end outward or rearward, consequently causing its pawl I' to engage and
turn the wheel H, this being permitted until the upper extremity of the segment of
the stop projection d has engaged the bail stop, when the movement of said bail
lever and wheel will be arrested, thus controlling the are or extent of the movement
of the wheel, which, by its engagement, as aforesaid, with the pinion P of the shaft
f
provides for the required rotation of the latter for the engagements of its pinions
with the pinions n of the-indicator wheels N.
The platen now being depressed, the numbering wheel C, is actuated through the
shafts, connection F and pawls e e, and the impression or record of said
recording wheels will be made on the surface of ribbon 1, which when the platen
returns to its elevated position, will be fed through its feeding mechanism so as to
present a fresh portion for a subsequent impression or record.
Also simultaneously with the elevation of the platen the racks A¹ will be returned
through the gear mechanism g1 g, &c., to their original position for a subsequent
forward movement as the platen shall be again depressed.
The indicator wheels N are actuated through the gearing n, n', P1, and shifted into
gear with the shaft P by the lever T' and N, engaged by the stud q' on the notation
key levers e¹, to disclose the duplicate of the record made by the wheels on the
ribbon l.
An adding attachment to this recording machine is indicated in rear of the
pinions P, T, T, designating the adding wheels, t, t, their pinions having shifting
connection with said wheels and actuated by levers T', having inclined slots t
engaging studs of the notation key levers. When a notation key is operated, the
lever Tis inclined sufficiently to effect the engagement of its pinion t, with a pinion P
of the shaft p, in order that the rotation of said shaft by the gear-turning devices in
connection with the digit keys may be effected.
Back of the wheels T and pinions t, are the carrying pinions ", which are actuated
each by a marginal notch or slot t11, of a pinion t, Fig. 5, when the digit 9 of said
wheel has passed its indicative position, and turns sufficiently to move the pinion t of
the next wheel one step.
By means of this adding attachment the transactions recorded by the type wheels
are summed up and the result is shown by the wheels T at the sight slot Y¹ of
the case.
In order to reset the wheels of the adding attachment to zero, the bail device U is
provided, which, when operated by the lever arm U', serves to actuate all the
notation key levers simultaneously. This action operates the angle lever U", to raise
the stop fingers u of the shaft u³ to engage the stop w, of the wheels T, and at the
saine time moves the slide-shaft p longitudinally, bringing its pinions in engagement
with the slot t1. Upon movement of one of the digit keys the entire series of
wheels T will be turned until stopped by the fingers u, and each of said wheels with
zero at the sight slot of the case.
The mechanism is designed to be enclosed in a secure encasement, having an
opening at Y; where the printing platen works, to facilitate the insertion of checks,

page_text: the entry of a recording strip, etc. The sight slots at Y and Y¹ are glazed, and the
door is provided with a safe lock, the key to which should be in the possession of
the party for whose information and security the machine is operated.
By means of these machines financial papers may be numbered and stamped with
their values and a regular record may be kept, showing each transaction by its
consecutive number and value.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
