Patent Agent.
"IMPROVED MACHINERY FOR RECORDING CASH TRANSACTIONS,
RECEIPTS, OR DISBURSEMENTS." [A communication from abroad by John Moss,
of the City, County, and State of New York, and John Henry Smith and George
Jay Hill, both of Buffalo, in the County of Erie, also in the State of New York,
United States of America.]
This Invention is to provide a machine for the purpose of keeping an exact record
of all cash transactions, receipts, or disbursements in warehouses, offices, manufac-
tories, or any business establishment or place where money is paid in.
It is also intended to be a check upon employees, and a prevention of dishonesty
by clerks or others handling money received or paid out in such establishments.
This is accomplished by registering on a paper strip inside the machine the amount
of any transaction, and printing or stamping the same amount simultaneously upon
the account, bill, or ticket inserted for that purpose, the two things being done at
one operation or movement by a lever handle, and the different amounts are set
in the machine for printing or stamping by knobs outside of the case attached to
the operating levers, all as herein-after fully described.
All the working parts of the machine are contained within a metallic casing. In
this casing is placed a frame consisting of two side pieces, which are connected

page_text: together by cross bars. This frame is pivoted to the front projecting portion of
the casing, and is guided at the rear end of the casing by a stud that projects down-
wardly from the frame through the bottom of the casing. Upon this stud between
the frame and bottom of the casing there is a spiral spring and a nut for limiting
the upward movement of the frame. Upon a pin which passes through the sides
of the frame there are several numbering wheels, each of which carries two sets of
numbers, and also two 1 marks, which are arranged on diametrically opposite sides
of the wheel, and upon one side of each numbering wheel there is a spur wheel
which is engaged by a rack, as hereafter described.
The numbering wheels each consist of a disc, which is slotted radially to receive
ordinary type, which are fastened in the slots by swaging out a portion of the
metal of which the wheel is composed into the nicks of the type. V shaped notches
are formed in the periphery of the type wheels to receive a registering bar which is
carried by a forked lever which extends across the frame and is pivoted to it at each
side.
To opposite sides of the frame sockets are secured for receiving on one side type
for printing the date, and upon the other side the word "paid," or its equivalent,
and fac simile of the cashier's signature, or any other device that would be appro-
priate to the use to which the recorder is applied. Below the sockets there are
curved standards which project upward, from the bottom of the casing, and have
screws in their upper ends to limit the downward movement of the frame, and thus
regulate the impression.
An arm carrying at its free end a pad or platen for pressing paper on the type
and numbering wheels is pivoted to a cross bar attached to the rear end of the frame.
This arm is drawn upwards by spiral springs, which are attached to the upper
portion of the casing, and it is pressed downwards by an angled lever that is
fulcrumed on a rod that projects from one side of the casing which is fixed
through the other side, which is removable. The long arın of this lever projects
upward through the top of the casing, and in the short arm a roller is pivoted,
which presses the upper surface of the arm carrying the pad or platen when the
lever is operated.
A rod provided with a collar and surrounded by a spiral spring is inserted in
a cavity in the lever, and extends through an apertured car that projects downward
from the top of the casing. The spring rests upon this ear, and by pressing against
the collar returns the lever to its normal position after the apparatus has been
operated.
From the top of the casing projects an arm having a stop screw to limit the
motion of the lever. The casing is hinged to a hollow base piece, which is provided
with glass windows in its sides, and also with a spring catch which engages the
casing, and prevents it from being turned on its hinges. This catch can be released
only when the removable side of the casing is taken from the machine.
Below the numbering wheels there is a table, which is secured to the bottom of
the base piece, and over which a paper strip passes, upon which are printed the
amount of cash receipts. This strip is drawn from a roll that is wound upon a
drum or spool supported in standards that project from the bottom of the base
piece.
From the table the paper strip passes between rollers, and thence downward to a
cylinder which is journalled in hangers that project downward from the bottom of
the casing, and upon which it is wound as it is discharged from the recording
machine.
One of the rollers is journalled in a frame hinged to the bottom of the casing,
and is forced into contact with the paper strip by a spring which rests against the
support of the table. The contact surface of this roller is inade shorter than the
width of the paper strip, to guide it and cause it to run straight through the machine.
The other roller is journalled in a curved standard, and is covered with soft rubber.
Upon one of the gudgeons of this roller a milled wheel is secured, and upon the
other there is a ratchet wheel, which is engaged by a spring hook pawl that is

page_text: carried by a vertically moving bar placed in guides at the side of the casing, and
operated by an arm that projects from the lever into a notch formed in the side of
the bar.
At the side of the frame there are two standards, in which are journalled; two
rollers for containing the inking ribbon which passes from one roller through a
slotted guide, and over the table and through a guide attached to the other side of
the frame, thence upward over guides and over the type in the sockets, and over
the numbering wheel and guide to the other roller.
The shafts of the rollers for the inking ribbon are each provided with a milled
wheel, by which they may be turned, and upon the shaft of one roller is a ratchet
wheel, which is engaged by a spring pawl attached to the vertically moving bar
above mentioned at every upward stroke of the said bar. By means of this vertically
reciprocating bar and the pawls attached thereto the paper strip is moved forward
to receive a new impression, and the inking ribbon is moved forward so as to.
present a new surface to the type.
The forked lever carrying the registering bar is provided with two cam ears,
which are engaged by a pin that passes through the pad or platen arm, so that
when the said arm descends the forked lever is moved so as to force the bar into
the notches of all the numbering wheels, and cause the line of the figures to register
correctly. The forked lever is returned to position after being moved by a
spring.
The removable side of the. casing when in place on the casing is secured by a
padlock.
The number wheels are operated by a series of racks which
engage the apur wheels,
and are connected at their rear ends with the spiral springs, which run over guide
pulleys. The springs are all attached to a rod that is supported by arins projecting
downward from the end of the frame.
The springs are capable of drawing the racks so as to rotate the number wheels
when the racks are released by the mechanism presently to be described.
The racks are attached at their forward ends to standards that are secured to
guide pieces that move along the upper surface of a slotted plate that is supported
by the frame.
The guide pieces are each provided with a stud that projects downward through
slots in the plate in position to be engaged by a cross head that is placed in guides
formed in the under surface of the slotted plate, and is attached to a rod that
projects through the front of the casing, and is provided with a head or handle by
which it may be drawn forward when it is desired to return all the printing wheels
to a blank. Upon this rod, between a collar and the front of the casing, a spring is
placed which carries the rod back after use. Upon the forward end of the guide
pieces there are bevelled nibs, which are engaged by spring catches, which are
pivoted to a cross bar which extends across the end of the frame. This cross bar
is apertured to receive a series of pins which rest on the spring catches, and extend
through the top of the casing, and are provided with knobs or thumb-pieces, which
are a little lower than the table, upon which is placed the bill to be checked. The
top of the casing is offset to admit of this arrangement.
Above and parallel with the guide pieces are hooks, which are pivoted to the
standards, and extend a short distance beyond the guide pieces. Between the said
guide pieces and hooks there are springs which are rivetted to the guide pieces, and
press the hooks upward. Above the hooks and parallel with the slotted plate is a
guide supported by the frame. In this block there are a number of transverse rows
of holes, the number of holes in each row being equivalent to the number of hooks,
nd the number of rows being equivalent to the number of characters or numbers
n each series on the numbering wheels.
In each of the holes there is a pin having a head, between which and the guide
here is a spring.
The lower end of each pin is provided with a hook or L shaped head that projects
oward the front of the machine.

page_text: Above each row of pins is placed a lever which is pivoted between ears that are
carried by the frame near the side of the casing, and projects through the opposite
side of the casing, and is provided with a thumb-piece, upon which is marked a
character or figure.
For convenience in handling these levers they are made in three lengths, the longer i
and shorter ones alternating.
There are nine rows of pins, which represent figures from 1 to 9 inclusive, and
also one row for the cipher, and one for the £1 mark.
There are as many figure wheels, thumb-pieces, and intermediate parts as there
are places for pounds, shillings, pence, and characters.
To each rack is attached a numbered strip, which projects towards the front of
the machine.
The figures and characters on each strip correspond with one of the sets of figures
and characters on the wheels, and there is a transverse slot in the table, on which
the bill to be checked is placed, through which one of the numbers on each of the
strips appears as the numbering wheels are adjusted, thus indicating the correctness
of the adjustment of the said wheels.
The portion of the casing that contains the arm carrying the pad and lever is
elevated above the table, and the casing is slotted at the sides to receive the bill to
be checked. The bill when inserted in the slots passes between the platen on the
end of the arm in position to be printed.
The end of the table which is nearest the type wheels is curved upward to guide
the bill, so that it passes readily over the number wheels.
The operation of setting the number wheels is as follows:-One of the thumb-
pieces which represents the place of the figure or character to be set is depressed.
This liberates the guide bar from the catch, and permits the hook and all of the parts
connected with it to move until the said hook engages a shoulder formed on the
guide. One of the levers which represents the required number or character is
depressed so as to project all of the pins in the row under the lever downward
through the guide. The pin immediately above the hook that has been started by
depressing the pin by this means disengages the hook from the shoulder when the
hook and the rack which is connected with it are moved by one of the springs until
the hook engages the hooked end of the pin, by means of which it was disengaged
from the shoulder. The hook is in this manner stopped so as to bring the required
figure on the indicating strip below the slot in the casing. The figure wheel by this
operation will have been turned so as to bring the required figure under the inking
ribbon and in a proper position under the platen. The corresponding figure on the
opposite side of the wheel is at the same time in the proper position to print on the
paper strip. As many figures and characters as may be required are thus thrown
into position for printing.
When the wheels are properly adjusted the bill, check, or other paper to be
receipted or printed on is inserted between the inking ribbon and the platen, and
the lever and arm are grasped in the hand, and the lever is forced toward the arm,
giving the impression upon the check and also upon the paper strip, the frame and
all contained or supported by it moving downward after the platen strikes the
type.
After the impression is made the parts are returned to their original position by
drawing the rod which projects through the front of the casing.
When the platen rises the paper strip is carried forward by the mechanism already
described, and the inking ribbon is moved a small distance to present a fresh surface
to the type.
The entire machine may be raised at any time to inspect the record on the paper
strip without disarranging any of the parts, or changing the adjustment.
At certain intervals, say at the end of the day, the strip may be cut, and the
detached portion filed.

"IMPROVED MACHINERY FOR RECORDING CASH TRANSACTIONS,
RECEIPTS, OR DISBURSEMENTS." A communication from abroad by John Moss,
of the City, County, and State of New York, and John Henry Smith and George
Jay Hill, both of Buffalo, in the County of Erie, also in the State of New York,
United States of America.
This Invention has for its object to provide a machine for the purpose of keep-
ing an exact record of all cash transactions, receipts, or disbursements in ware-
houses, offices, manufactories, or any business establishment, or place where money
is paid in.
It is also intended to be a check on employees, and a prevention of dishonesty
by clerks, or others handling money received or paid out in such establishments.
This is accomplished by registering on a paper strip inside the machine the
amount of any transaction and printing or stamping the same amount simul-
taneously upon the account, bill, or ticket inserted for that purpose, the two
things being done at one operation or movement by a lever handle and the different
amounts are set in the machine for printing or stamping by knobs outside of the
case attached to the operating levers, all as herein-after fully described.
In the accompanying Drawings, Figure 1 is a sectional side elevation of the
machine; Figure 2 is a plan view of same, partly in section; Figure 3 is a vertical
transverse section, taken on line x,-x, in Figure 1; Figure 4 is a vertical transverse
section, taken on line y,-y, in Figure 1; Figures 5 and 6 are detail views; Figure 7
is a sido elevation; Figure 8, a plan view; and Figure 9, a transverse section,
showing a modification of part of the machine.
Similar letters of reference indicate corresponding parts.
A, is the metallic casing which contains all the working parts of the machine.
In this casing is placed a frame B consisting of two side pieces a, a', which are
connected together by cross bars b, b¹. This frame is pivoted to the front projecting
portion of the casing at c, and is guided at the rear end of the casing by a stud d
that projects downwardly from the frame B through the bottom of the casing:
Upon this stud, between the frame B and bottom of the casing, there is a spiral
spring f, and upon the lower end of the stud, which is threaded, there is a nut g for
limiting the upward movement of the frame B. Upon a pin h, which passes
through the sides of the frame, there are several numbering wheels C, each of which
carries two sets of numbers and also two dollar marks which are arranged on dia-
metrically opposite sides of the wheel, and upon one side of each numbering wheel
there is a spur wheel i which is engaged by a rack, as will be presently described.
The numbering wheels each consist of a disc, which is slotted radially to receive
ordinary type j, which are fastened in the slots by swaging out a portion of the
metal of which the wheel is composed into the nicks of the type. shaped
notches are formed in the periphery of the type wheels to receive a registering
bar (Figure 1), which is carried by the forked lover m, which straddles the
frame B and is pivoted to it at each side.
To opposite sides of the frame B are secured sockets D (Figure 3) for receiving
on one side type for printing the date, and upon the other side the word "paid"
or its equivalent, and the fac simile of the cashier's signature, or any other device
that would be appropriate to the use to which the recorder is applied. Below the
sockets D there are curved standards E, which project upward from the bottom of
the casing A, and have in their upper ends screws n that limit the downward
movement of the frame B and thus regulate the impression.

page_text: An arm F, carrying at its free end a pad or platen for pressing paper on the type
and numbering wheels, is pivoted between cars o (Figure 1) that project from a
cross bar p attached to the rear end of the frame B. The arm F is drawn upward
by spiral springs which are attached to the upper portion of the casing A, and it is
pressed downward by an angled lever G that is fulcrumed on a rod r (Figure 3),
that projects from the fixed side of the casing A through the sides, which is
removable. The long arm of this lever G projects upward through the top of the
casing A, and in the short arm a roller t is pivoted, which presses the upper
surface of the arm F when the lever is operated.
A rod u provided with a collar and surrounded by a spiral spring w is inserted
in a cavity in the lever G, and extends through an apertured ear a that projects
downward from the top of the casing. The spring w rests upon the ear a³, and by
pressing against the collar v returns the lever G to its normal position after the
apparatus has been operated.
An arm be projects from the top of the casing A, and through it a stop screw c¹
passes to limit the motion of the lever G. The casing A is hinged to a hollow base
piece A2, which is provided with glass windows at its sides, and also with a spring
catch a which engages the casing A and prevents it from being turned on its
hinges. This catch can be released only when the removable side Š is taken from
the machine.
Below the numbering wheels C there is a table H which is secured to the bottom
of the base piece A2, and over which the paper strip d passes, upon which are
printed the amount of cash receipts. This strip is drawn from a roll that is wound
upon a drum or spool e', that is supported by standards es that project from the
bottom of the base piece A².
From the table H the paper strip passes between the rollers f, g, and thence
downward to a cylinder h', which is journalled in hangers that project downward
from the bottom of the casing A, and upon which it is wound as it is discharged
from the recording machine.
The roller is journalled in a frame that is hinged to the bottom of the
casing A, and is forced into contact with the paper strip by the spring j', which
rests against the support of the table H. The contact surface of the roller f¹ is
made shorter than the width of the paper strip, to guide it and cause it to run
straight through the machine. The roller g¹ is journalled in the curved standards E,
and is covered with soft rubber. Upon one of the gudgeons of this roller g'a
milled wheel 2 (Figure 3) is secured, and upon the other there is a ratchet wheel k¹,
which is engaged by a spring hook pawl that is carried by a vertically-moving
bar m' placed in guides at the side of the casing A, and operated by an arm n¹
that projects from the lever G into a notch formed in the side of the bar.
1
At the side of the frame B there are two standards o¹, in which are journalled
two rollers p, q, (Figure 3) for containing the inking ribbon, which passes from
the roller q through a slotted guide 81, and over table H, and through a guide &¹
attached to the other side of the frame B, thence upward over guides t¹, and over
the type in the sockets D, and over the numbering wheel C and guide u¹ to the
roller p
The shafts of the rollers p', q', are each provided with a milled wheel v', by
which they may be turned, and upon the shaft of the roller p¹ there is a ratchet
wheel a³, which is engaged by a spring pawl 6³ attached to the bar m² at every
upward stroke of the said bar. By means of the vertically reciprocating bar m¹
and the pawls attached thereto, the paper strip d' is moved forward to receive a new
impression, and the inking ribbon is moved forward so as to present a new surface
to the type.
The forked lever m is provided with two cam ears c², which are engaged by a
pin d that passes through the arm F, so that when the said arm descends the
forked lever is moved so as to force the rod into the notches k of all of the
wheels C, and cause the line of the figures to register correctly. The forked lever m
is returned to position after being moved by a spring f.

page_text: The removable side S of the casing A when in place is secured by a padlock e²,
whose hasp passes through a hole drilled in the end of the rod r.
The number wheels are operated by a series of racks g³, which engage the spur
wheels ¹, and are connected at their rear ends with the spiral springs h³ which run
ver pulleys i³.
The springs h² are all attached to a rod that is supported by arms ² that
project downward from the end of the frame B. The springs h² are capable of
drawing the racks, so as to rotate the number wheels when the racks are released
by the mechanism presently to be described.
The racks g are attached at their forward ends to standards m² that are secured
to the guide pieces n² that move along the upper surface of a slotted plate o² that is
supported by the frame B.
The guide pieces n² are each provided with a stud p² that projects downward
through slots in the plate in position to be engaged by a cross head q² that is placed
in guides formed in the under surface of the slotted plate o2; and is attached to a
rod that projects through the front of the casing, and is provided with a head or
handle S, by which it may be drawn forward when it is desired to return all of the
printing wheels to a blank. Upon this rod 2, between a collar 2 and the front of
the casing A, is placed a spring u³, which carries the rod 2 back after use. Upon
the forward end of the guide pieces n² there are bevelled nibs ², which are engaged
by the spring catches we which are pivoted to the cross bar b which extends across
the end of the frame B. This cross bar 6 is apertured to receive a series of pins 64,
which rest on the spring catches w³, and extend through the top of the casing A,
and are provided with knobs or thumb-pieces c³, which are a little lower than the
table d³ upon which is placed the bill to be checked. The top of the casing is off-
set to admit of this arrangement.
Above, and parallel with the guide pieces n², there are hooks e³, which are pivoted
to the standards m², and extend a short distance beyond the guide pieces n².
Between the said guide pieces and hooks there are springs f³, which are rivetted to
the guide pieces and press the hooks upward. Above the hooks c³, and parallel
with the slotted plate o², a guide g³ is supported by the frame B. In this block
there are a number of transverse rows of holes h³, the number of holes in each
row being equivalent to the number of hooks e³, and the number of rows being
equivalent to the number of characters or numbers in each series on the wheels C.
In each of the holes ³ there is a pin i³ having a head j³, between which and the
guide g³ there is a spring /³.
The lower end of each pin is provided with a hook or L shaped head 13 that
projects towards the front of the machine.
Above each row of pins is placed a lever m³, which is pivoted between ears that
are carried by the frame B near the side of the casing A, and projects through the
opposite side of the casing, and is provided with a thumb-piece n³, upon which is
marked a character or figure.
For convenience in handling these levers they are made in three lengths, the
longer and shorter ones alternating.
There are nine rows of pins , which represent figures from 1 to 9 inclusive, and
also one row for the cipher and one for the dollar mark.
There are as many figure wheels, thumb-pieces c³, and intermediate parts as there
are places for dollars, cents, and characters."
To each rack g² a numbered strip o³ is attached, which projects towards the front
of the machine.
The figures and characters on each strip correspond with one of the sets of figures
and characters on the wheel C, and there is a transverse slot p³ in the table d³,
through which one of the numbers on each of the strips appears as the numbering
wheels C are adjusted, thus indicating the correctness of the adjustment of the said
wheels.
The portion of the casing A that contains the arm F and lever G is elevated
above the table, and the casing is slotted at the sides to receive the bill to bo

page_text: checked. The bill when inserted in the slots passes between the platen g' on the
end of the arm F in position to be printed.
The end of the table which is nearest the type wheels is curved upward to
guide the bill, so that it passes readily over the number wheels.
The operation of setting the number wheels is as follows:-One of the thumb-
pieces c³, which represents the place of the figure or character to be set is depressed;
this liberates the guide bar n² from the catch w³, and permits the hook e³ and all of
the parts connected with it to move until the said hook engages a shoulder s³ formed
on the guide g³. One of the levers m³, which represents the required number or
character, is depressed so as to project all the pins in the row under the lever
downward through the guide g³. The pin immediately above the hook e³ that has
been started by depressing the pin 6 by this means disengages the hook e³ from
the shoulder 83, when the hook and the rack 92, which is connected with it, are
moved by one of the springs h² until the hook engages the hooked end of the pin 3,
by means of which it was disengaged from the shoulder 83. The hook e³ is in this
manner stopped, so as to bring the required figure on the indicating strip o³ below
the slot p³. The figure wheel C by this operation will have been turned so as to
bring the required figure under the inking ribbon, and in a proper position under
the platen g. The corresponding figure on the opposite side of the wheel is at the
same time in the proper position to print on the paper strip d¹. As many figures
and characters as may be required are thus thrown into position for printing.
When the wheels C are properly adjusted, the bill, cheque, or other paper to be
receipted or printed on is inserted between the inking ribbon 21 and the platen g¹,
and the lever G and arm 62 are grasped in the band, and the lever is forced towards
the arm b², giving the impression upon the cheque and also upon the paper strip d',
the frame B and all contained or supported by it moving downward after the platen
g strikes the type.
After the impression is made, the parts are returned to their original position by
drawing the rod by means of the knob S.
When the platen rises, the paper strip d' is carried forward by the mechanism
already described, and the inking ribbon is moved a small distance to present a fresh
surface to the type.
Referring now to the modification shown in Figures 7, 8, and 9, it will be seen
that the number wheels C in this instance are each moved by a rack g² projecting
from the slide e³, which is numbered at the top, and moves under the top plate in
the same manner as the number strips e³ in the other case. Each slide e' has a
knob e by which it may be moved. By this construction the springs h² are dis-
pensed with.
A notched bar q is carried by the slide e³, and is engaged by the
detent spring y. The slides are stopped by means of the keys n³, as in the previous
case.
The entire machine may be raised at any time to inspect the record on the paper
strip without disarranging any of the parts or changing the adjustment.
At certain intervals, say at the end of the day, the strip may be cut, and the
detached portion filed.
