I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of
Patent Agents, do hereby declare the nature of the said Invention for AN
IMPROVED TYPE-WRITING MACHINE FOR PRINTING, CUTTING OR STAMPING LETTERS,
FIGURES AND OTHER CHARACTERS a communication to me from abroad by
Darien W. Dodson, of Wilkes Barre, in the County of Luzerne, and State of
Pennsylvania, United States of America to be as follows:-
The object of this invention is to provide a new and improved type-writing
machine which is very compact, writes very rapidly, in which the keys need to be
depressed but slightly, and which exhibits the whole sheet as fast as written.
The invention consists in a type-writer constructed with one or more wheels
provided with teeth carrying types at the outer ends, which wheels are journalled
between two revolving discs surrounded by a casing provided on its inner surface
with an inking cushion or pad, with which the teeth of the type wheel or wheels
can come in contact, whereby the said type wheel or wheels will be rotated more
or less, so that when it arrives at a slot in the inking cushion or pad, a certain
letter will appear at the slot, and pass through the same and make an impression.
The said revolving discs are combined with a series of key levers, which if
depressed at the outer ends are raised at the inner ends, and turn the type wheel
or wheels in such a manner that the ends of the teeth of the same will come in
contact with the inking pad, whereby the said type wheel will be rotated. The
type wheel is not provided with teeth around its entire periphery, but has a blank
space, so that when the blank space appears at the slot in the inking pad, no
impression will be made.
The type wheel or wheels above mentioned is enclosed in a cylindrical casing
mounted upon a table, through which passes a vertical shaft provided at its lower
end with a bevelled cog-wheel which engages with a bevelled cog-wheel mounted
on a suitable shaft, which can be operated by means of a treadle, or by any other

page_text: suitable motor. On the upper end of the shaft two discs are rigidly mounted so a
to revolve therewith. The cylindrical casing which also encloses the revolving
discs is provided in its front with a slot through which the key levers pass which
are all pivoted on a transverse rod.
The key levers have their outer ends bent and arranged so that the keys on the
outer ends of the said levers will form a very small circle, the keys being. very.
small, as they are not to be operated by the fingers, but by means of a stylus.
The keys are all provided with letters, marks, figures etc. in the usual manner, and
one lever is provided with a key, which is outside of the circle of keys, but may be
within the circle. The object of this key will be described hereinafter. Between
the revolving discs a series of horizontal wheels are journalled, which project
beyond the edges of the discs and are provided on their peripheries with a series of
teeth carrying the letters, as many teeth being provided as there are key levers.
Each type wheel is provided with a blank space equal to about one fifth of the
circumference, the edge of the said blank space being within the circle formed by
the outer ends of the teeth. Each type wheel is provided with an aperture adapted
to receive a pin held loosely in the upper revolving disc in such a manner. that it
can pass freely through the said disc, which pin is held on the outer free end of a
spring secured to the top of the said upper disc. The free ends of the several
springs are bent rectangularly and are arranged on a circular line near the centre
of the upper surface of the upper revolving disc so that they can pass upon a semi-
circular cam track held on the under surface of the cover of the casing. Each type
wheel is provided on its under surface with a stud which is just in the middle of
the recessed part. On the under side each wheel is also provided with a bevelled
stud at the beginning of the row of teeth and on its upper surface, each wheel is
provided with a triangular or bevelled tooth, which is adapted to engage with a
series of triangular teeth of a segmental rack secured to the inner surface of the
cylindrical casing. The casing is also provided on its inner surface with an inking
pad or cushion of leather rubber or analogous material for inking the type which is
such a distance from the centres of the type wheels that when the teeth of the
wheels are presented to the said surface, they will catch on the same and will
revolve the wheels, but if the recessed or blank parts are presented to the surface
they will not catch on the same, and the wheels will not be revolved. The said
cushion or pad is gradually narrowed down toward a vertical slot in the same,
opposite which slot a vertical bar or rod is. held, and between the edge of, which
bar and the outer surface of the cushion or pad, which at that point forms a very
thin and elastic diaphragm, the sheet of paper to be written on is held by ineans of
suitable devices. Any one of the teeth of the wheels carrying the letters or type
can pass through the slot and can make an impression on the paper. Every time
an impression or an imprint has been made the paper must be moved the distance
of one letter.
.
"
The paper is held in a paper carrier which stands vertically and is at an angle
of about 45° to the longitudinal axis of the key levers, so that a person sitting or
standing in front of the circle of keys can see the sheet of paper: held in the paper
holder. The said paper holder is adapted to move from right to left: In order to
move the paper holder a suitable distance after each letter has been printed, a
vertical spring is held in a recess in the cylindrical casing, in such a manner that
the upper end of said spring can be pressed outward.
j
The upper end of the said spring is. provided with a head of rubber, leather or
analogous material, which head is so located that it can be acted upon by the teeth
of the type wheels and can be pressed outward. The spring is provided at about
its middle with an outwardly projecting tooth which is so located that it can act
on the bevelled teeth of a rack on the paper carrier in a manner that will be
described hereinafter. ::
The key levers are provided at their inner ends with upwardly projecting arms
which are each provided at the upper end with a laterally projecting arm
terminating in a triangular or bevelled tooth. One, type wheel only may. ibe

page_text: pivoted between the revolving discs or a number of type wheels may be provided
in which case the machine will operate much more rapidly. The revolving discs on
the vertical shaft must make one revolution for every letter printed, but if more
type wheels are provided more imprints than one can be made for each revolution
of the discs. The paper carrier is provided with pulley wheels and with suitable
devices for adjusting the sheet of paper higher or lower by hand as may be
desired.
I will now describe the operation of one type wheel, all the type wheels
operating in the same manner. If the pin before mentioned is in the aperture or
recess in the wheel it will be locked in such a position that its recessed part will
face the surface of the inking pad. As the discs rotate the end of the spring
carrying the pin above referred to travels upon the cam track on the underside of
the cover of the cylindrical casing and thereby raises the outer end of the spring
and draws the pin upward thereby releasing the type wheel which is now free to
turn. If the type wheel is not set in motion, or partly turned by means of a key
lever it remains in the position it had when released and if the end of the spring
has passed over the cam track, the spring snaps down and presses the pin into the
aperture of the wheel again thus holding the said wheel locked in position during,
the rest of the revolution. The wheel is thus locked during half of the revolution,
and unlocked during the other half. If, as soon as the wheel is released it is partly
rotated by means of some suitable devices, the types on the ends of the teeth will
be brought in contact with the surface of the inking pad and the friction will
revolve the wheel more or less, and accordingly as the said wheel is revolved a
greater or less distance one or the other tooth will pass into the vertical slot in the
diaphragm of the inking pad or cushion when the type wheel arrives at the said
slot. For instance, if the wheel is revolved, a great distance, the tooth carrying
the letter "E" would be in position to pass through the slot when the wheel
arrives at the said slot; or if the wheel is revolved but a short distance the
letter "M" might be in such a position as to pass through the slot when the wheel
arrives at the said slot and so on. Thus it is evident that the different letters can
be caused to project through the slot according to the time at which the wheel is
caused to rotate, that is according to the time at which the wheel is moved so that
its teeth will engage with the surface of the pad.
In order that the writing shall not be blurred, and the edges of the slot shall
not be injured, it is absolutely necessary that the wheels shall rotate a precise and
certain distance, which result is ensured by providing a rack on the inside of the
casing and the triangular teeth on the type wheels.
If a wheel begins to rotate its triangular tooth must first pass between two
triangular teeth of tho rack, and the position of the wheel is thus fixed.
The wheel then revolves the distance of a certain number of teeth, and the
distance it revolves will always be equal to the length of one or more teeth, that is
the wheel can never revolve the distance of a number of teeth and a fraction of a
tooth. The rack teeth are so spaced and arranged in relation to the slot in the
diaphragm that whether the wheel revolves the distance of one, two, five, fifteen
or any number of rack teeth the tooth which is at the slot will always pass
squarely through the slot, and will not strike against the edges of the same. It
next remains to start the type wheels in such a manner that they will revolve the
required distance to bring the desired letter- to the slot at the desired time. For
this purpose the key levers are so arranged that they will start the type wheels at
different times. For instance, if a letter is to be printed which is so located on
the type wheel that the wheel must make almost an entire revolution in order to
bring that letter to the slot at the proper time, the key lever must be so arranged
that the wheel will be started a considerable time before the said wheel arrives at
the slot. The other key levers must be arranged in a corresponding manner, so
that the wheel will be started sooner or later as may be required according to the
position of the tooth of the desired letter on the rim of the wheel. If the outer
end of a key lever is depressed, its inner end will be raised, and the stud on the

page_text: underside of the wheel will strike against the upper end of the arm on the end of
said lever whereby the wheel will be rotated sufficiently to cause the first tooth to
come in contact with the surface of the inking pad and whereby the said wheel
will be rotated more or less, accordingly as its tooth has been brought in contact
with the pad a greater or less distance from the slot. As the wheel, passes over
the lateral arm at the upper end of the arm on the key lever, the tooth on the
bottom of the wheel strikes against the beveled tooth on the said arm of the key
lever, and presses the same downward so that it will be in position to be raised
immediately in case the same letter is to be printed over again by means of another
wheel. If desired, springs may be provided for pressing the inner ends of the key
levers downward. It would not seem necessary that the type wheel should rotate
after the impression has been made, but the diaphragm which is a continuation of
the inking pad or cushion is carried beyond the slot so that the wheel will be
rotated atter it has passed the slot so that the pin can snap into the aperture in the
wheel for the purpose of locking the same in place as before mentioned. Just
after passing the slot the wheel encounters the head of a spring and presses the
upper end of the said spring outward, thereby pressing its tooth outward and
against one of the beveled teeth of the rack of paper carrier and moving the rack
the distance of one tooth. As soon as the wheel has passed, the spring is thrown
back by its own tension. If a blank is to occur in the line of writing it is
necessary that the paper shall be moved the distance of a letter but yet no
impression be made. For this purpose one of the key levers is so arranged that
when it is depressed, it revolves the type wheel to such an extent that the blank
or recessed part will be at the slot and thus no impression will be made, but at
the same time the teeth will press the diaphragm outward after passing the slot
and the upper end of the spring will be pressed outward to cause the paper-carrier
to move the paper a short distance. As stated above I do not propose to use the
ordinary finger keys, such as are used in type writers; but to use very small keys
which are to be operated by means of a stylus; thus permitting a person to operate
very rapidly For this reason, it is necessary that the levers shall be raised but a
very short distance, and this can be accomplished by means of this improved
machine, as the levers do not make the impression but start a wheel in such a
inanner that it will make the impression The throw of the levers is very slight,
and by suitably pivoting the levers they can be arranged so that the least
depression at the key end will be sufficient to operate the machine. The machine
can be provided with a lever for each letter, or any number of additional letters,
numbers, signs, etc, can be provided, as may be desired. The type wheels must be
absolutely alike.
The discs are to be revolved continually and may be in the form of a wheel with
spokes in which case the type teeth will be outside of the tire. The discs may be
arranged to revolve in the vertical plane if desired by simply changing such parts
as may be necessary to adapt the type wheels to the motor the keys and the paper
carrying device.
Instead of providing each type wheel with a single cog it may be provided with
a sufficient number to engage with the rack during the entire revolution or the
rack and cogs can be dispensed with entirely.
Instead of printing the letters as described, the machine may also be constructed
in such a manner as to cut or stamp the letters, or in place of cutting, printing or
stamping letters, the machine may be arranged to cut, stamp, or print figures or
other characters used in writing or printing, the said characters to be cut, stamped
.or printed from type, stamps, plates or dies of paper, wood, metal, or other
material.

I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of
Patent Agents, do hereby declare the nature of the said Invention for AN
IMPROVED TYPE-WRITING MACHINE FOR PRINTING, CUTTING OR STAMPING LETTERS,
FIGURES AND OTHER CHARACTERS (a communication to me from abroad by
Darien W. Dodson, of Wilkes Barre in the County of Luzerne and State of
Pennsylvania, United States of America) and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
1
The object of this invention is to provide a new and improved type writing
machine which is very compact, can write very rapidly and in which the keys
must be depressed but slightly, and which exhibits the whole sheet as fast as
written.
The invention consists in a type writer constructed with one or more .wheels
provided with teeth carrying types at the outer ends which wheels are journaled
between two revolving discs surrounded by a casing provided on its inner surface
with an inking cushion or pad, with which the teeth of the type wheel or wheels
can come in contact whereby the said type wheel or wheels will be rotated more or
less so that when it arrives at a slot in the inking cushion or pad a certain letter
will appear at the slot, and pass through the same and make an impression.
The said revolving discs are combined with a series of key levers which if
depressed at the outer ends are raised at the inner ends, and turn the type wheel or
wheels in such a manner that the ends of the teeth of the same will come in contact
with the inking pad whereby the said type wheel will be rotated. The type wheel
is not provided with teeth around its entire periphery, but has a blank space so that
when the blank space appears at the slot in the inking pad, no impression will be
made.
Reference is to be had to the accompanying drawings forming part of this
specification in which similar letters of reference indicate corresponding ports in all
the figures.
Figure 1 is a plan view of my improved type writing machine parts being broken
out. Figure 2 is a longitudinal sectional elevation of the same. Figure 3 is a per-
spective view of the inner end of one of the key levers
Figure 4 is an inverted plan of one of the printing wheels. Figure 5 is a
sectional plan view of part of the machine, showing the device for moving the
paper.
Figure 6 is a cross sectional elevation of the same.
A vertical shaft A passes through the top plate A' of a table and is provided at
its lower end with a bevelled cog-wheel A2, which engages with a beveled cog-wheel
mounted on a suitable shaft which can be operated by means of a treadle or by any
other suitable motor. On the upper end of the shaft A two discs B are rigidly
mounted so as to revolve with the said shaft. A cylindrical casing C surrounds the

page_text: revolving discs B B and is provided in its front with a slot C¹ through which the
key levers D pass which are all pivoted on a transverse rod C². The key levers
have their outer ends bent and arranged as shown in Figure 1, so that the keys d
on the outer ends of the said levers will form a very small circle, the keys being
very small as they are not to be operated by the fingers, but by means of a stylus.
The keys are all provided with letters, marks, figures etc, in the usual manner and
one lever D¹ is provided with a key d¹, which is outside of the circle of keys, but
may be within the circle. The object of this key will be described hereinafter.
Between the discs B, B a series of horizontal wheels E, are journaled, which project
beyond the edges of the discs. The said wheels E are provided on their peripheries
with a series of teeth El carrying the letters, as many teeth E¹ being provided as
there are key levers D. Each wheel E is provided with a blank space E2 equal
to about one fifth of the circumference, the edge of the said blank space E² being
within the circle formed by the outer ends of the teeth E. Each wheel E is
provided with an aperture S adapted to receive a pin F held loosely in the top
disc B, in such a manner that it can pass freely through the said disc, which pin F
is held on the outer free end of a spring F¹ secured to the top of the upper disc.
The free ends F" of the several springs F1 are bent rectangularly and are arranged on
a circular line near the centre of the upper surface of the upper dise B so that they
can pass upon a semi-circular cam track G held on the under surface of the cover
of the casing C. Each wheel E is provided on its under surface with a stud H
which is just in the middle of the recessed part E². On the under side each
wheel is also provided with a beveled stud I at the beginning of the row of teeth E¹
and on its upper surface, each wheel is provided with a triangular or beveled
tooth J, which is adapted to engage with a series of triangular teeth K¹ of a
segmental rack K secured to the inner surface of the cylindrical casing C. The
cylindrical casing C is provided on its inner surface with an inking pad or cushion L
of leather rubber or analogous material, which is such a distance from the centres
of the wheels E, that when the teeth of the wheels are presented to the said
surface, they will catch on the same and will revolve the wheels, but if the
recessed or blank parts E2 are presented to the surface, they will not catch on the
same, and the wheels will not be revolved. The said cushion or pad L is gradually
narrowed down towards a vertical slot L¹ in the same, opposite which slot a vertical
bar or rod N is held and between the edge of which bar N and the outer surface of
the cushion or pad L, which at that point forms a very thin and elastic diaphragm L³,
the sheet of paper O to be written on is held by means of suitable devices. Any
one of the teeth E¹ carrying the letters or type can pass through the slot L' and
can make an impression on the paper O. Every time an impression or an imprint
has been made, the paper must be moved the distance of one letter.
The paper is
held in a paper carrier P which stands vertically and is at an angle of about 45° to.
the longitudinal axis of the key levers, so that a person sitting or standing in front
of the circle of keys d, can see the sheet of paper held in the paper holder. The
said paper holder is adapted to move from right to left. In order to move the
paper holder a suitable distance after each letter has been printed, a vertical
spring is held in a recess Q¹ in the cylindrical casing C, in such a manner that
the upper end of said spring can be pressed outward. The upper end of the said
spring is provided with a head Q2 of rubber, leather or analogous material, which
head is so located that it can be acted upon by the teeth of the wheels E and can
be pressed outward. The spring Qis provided at about its middle with an
outwardly projecting tooth m which is so located that it can act on the beveled
teeth-n of a rack N₁ of the paper carrier P, in a manner that will be described
bereinafter. The cushion L is provided with ink and forms a pad for inking the
type. The key levers D are provided at their inner ends with upwardly projecting
arms M which are each provided at the upper end with a laterally projecting arm M
terminating in a triangular or beveled tooth M². One wheel E only may be pivoted
between the discs B, or a number of wheels E as shown, may be pivoted between

page_text: the same.
If more than one wheel E is provided, the machine will operate much
more rapidly than if one wheel E only is provided. The discs B on the shaft A
must make one revolution for every letter printed, but if more wheels E are
provided, more imprints than one can be made for each revolution of the discs B.
The
paper carrier P is provided with pulley wheels P¹ and with suitable devices for
adjusting the sheet of paper higher or lower by hand as may be desired.
The operation is as follows:-
I will now describe the operation of one wheel E, all the wheels E operating in
the same manner. If the pin F is in the aperture or recess S of the wheel E, the
wheel E will be locked in such a position that its recessed part E' will face the
surface of the inking pad L. As the discs B rotate in the direction of the arrow a¹,
the end F of the spring F¹ passes upon the cam track G, and thereby raises the
outer end of the spring F¹ and draws the pin F upward, thereby releasing the
wheel E which is now free to turn. If the wheel E is not set in motion or partly
turned, by means of a key lever, it remains in the position it had when released
and if the end F* of the spring F¹ has passed over the cam track G, the spring
snaps down and presses the pin F into the aperture of the wheel E again, thus
holding the said wheel locked in position during the rest of the revolution. The
wheel is thus locked during half of the revolution, and unlocked during the other
half. If as soon as the wheel is released, it is partly rotated by means of some
suitable devices, the types on the ends of the teeth E¹ will be brought in contact
with the surface of the pad L and the friction will revolve the wheel E more or
less, and accordingly as the said wheel E is revolved a greater or less distance, one
or the other tooth will pass into the slot L' of the diaphragm L' when the wheel E
arrives at the said slot. For instance, if the wheel is revolved a great distance, the
tooth carrying the letter "E" would be in position to pass through the slot L¹
when the wheel E arrives at the said slot, or if the wheel is revolved but a short
distance, the letter "M" might be in such a position as to pass through the slot L1,
when the wheel E arrives at the said slot and so on. Thus it is evident that the
different letters can be caused to project through the slot L' according to the time
at which the wheel E is caused to rotate; that is according to the time at which
the wheel E is moved so that its teeth will engage with the surface of the pad. In
order that the writing shall not be blurred, and the edges of the slot L' shall not
be injured, it is absolutely necessary that the wheels shall rotate a precise and
certain distance, which result is ensured by providing a rack K on the inside of the
casing C and the triangular teeth J on the wheels E. If a wheel begins to rotate,
its triangular tooth J must first pass between two triangular teeth K¹ of the
rack K and the position of the wheel is thus fixed. The wheel E then revolves the
distance of a certain number of teeth, and the distance it revolves will always be
equal to the length of one or more teeth, that is the wheel E can never revolve the
distance of a number of teeth and a fraction of a tooth. The teeth K¹ are so
spaced and arranged in relation to the slot L¹, that whether the wheel E
revolves the distance of one, two, five, fifteen or any number of teeth K³, the
tooth E which is at the slot L' will always pass squarely through the
slot, and will not strike against the edges of the same. It next remains to start
the wheels E in such a manner that they will revolve the required distance to bring
the desired letter to the slot L' at the desired time. For this purpose the key
levers D are so arranged that they will start the wheels E at different times. For
instance if a letter is to be printed, which is so located on the wheel E, that the
wheel E must make almost an entire revolution in order to bring that letter to the
slot L at the proper time; the key lever must be so arranged that the wheel E
will be started a considerable time before the said wheel arrives at the slot L. The
other key levers must be arranged in a corresponding manner, so that the wheel E
will be started sooner or later as may be required according to the position of the
tooth of the desired letter on the rim of the wheel. If the outer end of a key lever D
is depressed, its inner end will be raised and the stud H on the underside of the
wheel E will strike against the upper end of the arm M, whereby the wheel will

page_text: be rotated in the direction of the arrow b¹ sufficiently to cause the first tooth E¹ to
come in contact with the surface of the inking pad L, whereby the said wheel will
be rotated more or less, accordingly as its tooth has been brought in contact with..
the pad L, a greater or less distance from the slot L. As the wheel passes over
the arm M at the upper end of the arm M, the tooth I on the bottom of the wheel
strikes against the beveled tooth M³ on the end of the lever D, and presses the
same downward so that it will be in position to be raised immediately, in case the
same letter is to be printed over again by means of another wheel. If desired,
springs may be provided for pressing the inner ends of the .levers D downward.
It would not seem necessary that the wheel E should rotate after the impression
has been made, but the diaphragm L' which is a continuation of the pad or
cushion L is carried beyond the slot L' so that the wheel E will be rotated after
it has passed the slot L, so that the pin F can snap into the aperture S for the
purpose of locking the wheel E in place. Just after passing the slot L', the wheel E
encounters the head Q of the spring Q and presses the upper end of the said
spring outward, thereby pressing its tooth m outward and against one of the
beveled teeth n of the rack N¹ and thereby moving the rack in the direction of
the arrow c', the distance of one tooth n. As soon as the wheel has passed, the
spring is thrown back by its own tension. If a blank is to occur in the line
of writing, it is necessary that the paper shall be moved the distance of a letter,
but yet no impression be made. For that reason one of the key levers which in
this case is D¹, is so arranged that when it is depressed, it revolves the type wheel
to such an extent that the blank or recessed part E will be at the slot L and thus
no impression will be made, but at the same time the teeth E will press the
diaphragm L outward after passing the slot L' and the upper end of the spring Q
will be pressed outward to cause the paper carrier to move the paper a short
distance in the direction of the arrow c¹. As stated above I do not propose to use
the ordinary finger keys, such as are used in type writers, but to use very small
keys which are to be operated by means of a stylus; thus permitting a person to
operate very rapidly.. For this reason it is necessary that the levers D shall be
raised but a very short distance, and this can be accomplished by means of this
improved machine, as the levers do not make the impression, but start a wheel in
such a manner that it will make the impression. The throw of the levers is very
slight and by suitably pivoting the levers D they can be arranged so that the least
depression at the key end will be sufficient to operate the machine As stated
above the shaft A can be revolved by means of foot power, or by means of a
suitable motor, as may be desired. The machine can be provided with a lever for
each letter or any number of additional letters, numbers, signs, etc, can also be
provided, as may be desired. The wheels E must be absolutely alike.
The discs B are to be revolved continually and may be in the form of a wheel
with spokes, in which case the type teeth will be outside of the tire. The discs B
may be arranged to revolve in the vertical plane if desired, by simply changing
such parts as may be necessary to adapt the type wheels to the motor, the keys and
the paper carrying device.
Instead of providing each type wheel with a single cog, it may be provided with
a sufficient number to engage with the rack during the entire revolution or the
rack and cogs can be dispensed with entirely.
Instead of printing the letters as described the machine may also be constructed
in such a manner, as to cut or stamp the letters, or in place of cutting, printing or
stamping letters, the machine may be arranged to cut, stamp, or print figures or
other characters used in writing or printing, the said characters to be cut, stamped
or printed from type, stamps, plates or dies of paper wood metal or other material.
