IN PART APPLICABLE TO OTHER PURPOSES 35
a communication to me from Ignacio
Marguis [sic] of Camarasa a person resident at Madrid in the Kingdom of Spain
This Invention has for its object Improvements in and apparatus for the
reproduction of writings drawings or the like and relates to such reproduction by
firstly writing or drawing with mechanical needle pins supported and operated by
an elastic cord above a suitable work table-The Invention also relates to the
means for supporting and working the said pens and to the mode of arranging
and protecting the mechanism for driving the pens and the devices employed for
reproducing the perforated originals obtained by their use. Also to the means
employed for stretching and obtaining impressions from the perforated sheets or
originals representing any required writing or design by means of a series of closely
arranged dots,
The improved mechanical pens arranged according to this Invention being
carried by a suitable support may be employed not only for obtaining perforated
sheets as originals from which impressions or Copies may be obtained but also
serve to produce upon commercial and other like documents perforated or
punctured indications visible by transparency and which do not obscure the
indications written or printed upon the same sheet.

page_text: These pens may also be employed for cutting out patterns dividing stamps
receipts coupons and the like which require to be rendered capable of being
readily detached or separated
When the needle is replaced by a lithographic or other pencil the pens may be
used for lithographic and other like work in which certain effects of shade and the
like are required to be produced by means of a great number of closely arranged
dots.
The employment of these pens is facilitated by various systems of supports
whose object is to sustain by means of an elastic cord so much of the weight as is
not required for the work and also to assist the operation of bringing the pens into
action by means of treadles clockwork or a steam gas clectric or other motor.
These supports dependent or independent are combined and jointed in such a
manner that they may be brought into a very small compass and the pens and
mechanism may be protected when not in use and are also so arranged as to
facilitate the employment of the various parts required for the reproduction of the
perforated sheets obtained by means of the mechanical pens.
These parts include:―
1. A flat or curved frame made in two parts and serving to stretch the perforated
sheet
2. A fixed or moveable printing table carrying the sheets to be printed.
3. Stationary inking rollers which when passed ovor the perforated sheet reproduce
the writing or design punctured in the latter upon the sheets to be printed which
are placed between the perforated-sheet and the table.
The pens constructed according to this Invention are provided with a needle
contained in a sheath forming the handle of the pen-This sheath is connected at
the upper extremity with a frame carrying a small grooved pulley turning, upon
centre points as hereinafter described and driven by an electrical supporting cord.
The motion thus imparted to the pulley is transmitted to the needle whose point
protrudes slightly at the conical extremity of the sheath or handle and punctures
the paper placed beneath it.
The Motion is transmitted directly to the needle by means of Cams or their
equivalents on the axis of the grooved pulley acting upon the extremity of the
needle by the intervention of friction rollers or otherwise. The extremity of the
needle may be provided with two arms passing on opposite sides of the pulley and
bearing against two corresponding cams or one arm only may bear against a cam
the other arm being utilized as a guide-The cam or cams may operate the needle
in both directions or in one direction only the movement in the opposite direction
being obtained by means of a spring acting on one arm of the fork or on a collar on
the stem of the needle for example-A hoop or rod on one or both sides of the pulley
is employed to prevent the cord from running out of the groove of the latter.
The sheath of the needle may form the handle of the pen as hereinbefore stated
but this arrangement renders it necessary to hold the pen vertically or perpen-
dicularly to the paper which renders a certain amount of practice necessary to
enable the pen to be used with advantage.
In order to remedy this objection also common to electric pens the needle and
its sheath are shortened and connected to an arm set at a suitable angle say about
forty degrees 'with the axis of the needle and provided with a socket for the
reception of an ordinary handle or pen holder thus enabling the pen to be used in
the same manner as an ordinary writing pen.
The extent to which the point of the needle protrudes from the sheath is
adjusted by shortening or lengthening the latter by means of a telescopic or
equivalent arrangement the parts of the sheath being caused to slide telescopically
one over the other by means of a screw or rack at the side. According to another
and preferable arrangement one part of the sheath is provided with a male screw
engaging with a female screw on the other part so that the length of the sheath
can be adjusted by simply rotating one of the parts relatively to the other means
L· + . J

page_text: such as ratchet and spring catch operated by hand being provided to prevent the
screws from turning accidentally.
The arms of the fork acted on by the cam or cams as hereinbefore described may
be guided by working in eyes attached to the frame or by working in recesses in
the sides of the frame or by any other equivalent arrangement.
The pens are suspended by an elastic cord passed round the grooved pulley
hereinbefore described and over an over head cylinder being so adjusted that the
hand of the operator is relieved of unnecessary weight and a slight prossure
suffices to draw the cord tight and to bring the pen at the same time into contact
with the paper.
The said cylinder is caused to rotate by any suitable means and drives the said
grooved pulley by means of the elastic cord thus imparting a rapid reciprocating
motion to the needle of the pen which is guided over the surface of the paper by
the hand of the operator-The top of the table is preferably made in the form of
a box in which the overhead cylinder and the standard or upright by which the
same is supported may be packed together with the pen when not in use.
The support of the over head cylinder is preferably made in sections of
convenient length connected together by screws or other convenient arrange-
ments The box forming the top of the table also serves as a receptacle in which
to pack away the perforated sheets and apparatus for printing hereinafter described
and is preferably hinged to the leg or pillar on which it stands so as to be capable
of being turned up into a vertical position in order to economize space.
According to another arrangement the vertical sides of the box are made in the
form of flaps hinged to the bottom and which when turned down into a horizontal
position forin extensions of the table. When the pen is in use the box is .closed
and the sheet to be perforated laid on the top but when employed for printing
copies the sides are turned down and the lid turned back so as to form an elevated
shelf or desk for the reception of the blank or printed sheets the pen and its
appurtenances being stowed away at one end of the box.
In order to obtain printed Copies by means of sheets that have been punctured
or perforated by means of the apparatus herein before described the sheets are
stretched upon a specially constructed apparatus hereinafter described consisting
of two rectangular frames of equal size one of which is provided with a ridge or
tongue along two sides capable of entering a corresponding groove or recess in the
other frame One of the frames is moreover provided with sharp pins projecting
beyond the ridge or tongue and also with longer pins or bolts serving as guides-
The perforated sheet is pressed down over the sharp pins and is then stretched by
being pressed by the tongues into the grooves herein before described. Hinged
bolts connected to the lower frame and provided with thumb nuts are then caused
to engage with suitablo projections on the upper frame and the two frames are
pressed firmly together by means of the nuts.

The sheet that is to receive the impression is laid upon an imposing table or
block which fits into the lower frame carrying the perforated sheet, being
provided with a projecting ledge at its edges which supports the frames in such a
position that the top of the block is flush with the division between the frames.
This block may also be used to support the perforated Sheet during the operation
of fixing it in the frames. In printing, the perforated Sheet is placed in position
upon the blank Sheet previously deposited on the top of the block and an inking
roller is then passed over the perforations which allow the ink to penetrate to tho
surface of the blank sheet and reproduce thereon the writing or design punctured
in the perforated Sheet which with the frames is then removed and the printed
Copy exchanged for a fresh blank sheet with which the same operations are
repeated.
These operations demand great care on the part of the operator and in order to
facilitate the work the frame is provided on its underside with guide bars
extending behind the lower frame where they are turned upwards thon downwards

page_text: and secured to the side of the said frame. Two stationary studs or pins, one on
each side of the imposing table engage between these bars and the frame which
slides upon the pins and is thereby guided to the proper position over the
imposing table. The frames are preferably constructed with three sides only when
this arrangement is employed in order to enable the frames to be readily removed.
from the block by lifting one end of the former and then sliding them horizontally
on the stationary pins or Studs herein before described.
The inking may be performed with hand rollers but it is more advantageous to
'employ inking rollers supported in stationary bearings and to cause the printing
table with the perforated sheet to slide underneath this roller by means of a rack
and pinion or other equivalent arrangement which may be operated by the treadles
'or other motor employed to drive the mechanism connected with the pen.
The moveable table may be constructed in the form of a segment of a hollow
cylinder or in the form of a complete cylinder, the inking roller being applied to
either the outer or inner surface of such cylinder and may be combined with any
suitable automatic apparatus for removing or supplying the Sheets to be printed.
The inking roller may be stationary the cylindrical table turning on its axis, or
the table may be stationary and the roller caused to describe an arc about the
centre of the cylinder.
The pressure of the inking rollers employed in combination with the horizontally
sliding table hereinbefore described is regulated by means of a lever and counter-
weight oscillating on a fixed centre or by an adjustable spring and may receive
the supply of ink from a second roller whose pressure is adjusted in like manner
and which partakes of a reciprocating motion in the direction of its axis in order
to distribute the ink more uniformly. If preferred the ink may be supplied in
the same manner as in large lithographic presses or otherwise or the inking roller
may be dispensed with, the ink being applied to the perforated Sheet by means
of a pad operated by a spring or treadles or other suitable mechanism.

JOHN HENRY JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman "IMPROVEMENTS IN THE REPRODUCTION OF WRITINGS DRAWINGS OR
THE LIKE AND IN THE APPARATUS EMPLOYED THEREIN OR CONNECTED THEREWITH
"
IN PART APPLICABLE TO OTHER PURPOSES a communication to me from Ignacio
Marquis de Camarasa, a person resident at Madrid in the Kingdom of Spain.
My Invention has for its object improvements in and apparatus for the
reproduction of writings drawings or the like and relates.
(a) To needle pens operated by and suspended from a cord above the work
table
b) To means for supporting and working the said pens and to a mode of
arranging and protecting the mechanism for driving the pons and the devices
employed for obtaining impressions from the perforated originals produced by
their use.
c) To the means employed for stretching and obtaining impressions from the
perforated sheets or originals representing any required writing or design by means
of a series of closely arranged dots.
The improved mechanical pens arranged according to this Invention being
carried by a suitable support may be employed not only for obtaining perforated
sheets as originals from which impressions or copies may be obtained but also
serve to produce upon commercial and other like documents perforated or punctured
indications visible by transparency and which do not obscure the indications
written or printed upon the same sheet. These pens may also be employed for
cutting out, patterns dividing stamps receipts coupons and the like which require
to be rendered capable of being readily detached or separated. When the needle
is replaced by a lithographic or other pencil the peus may be used for lithographic
and other like work in which certain effects of light and shade are required to be
produced by means of myriads of closely arranged dots.
The employment of these pens is facilitated by various systems of supports
whose object is to sustain by means of an elastic cord so much of the weight of
the instrument as is not required for the work and also to facilitate operating the
pens by means of treadles clock work or a steam gas electric or other motor-These
supports whether dependent or independent are combined and jointed in such a
manner that they may be brought into a very small compass and the pens and
mechanism inay be protected when not in use and are also so arranged as to
facilitate the employment of the various appliances required for obtaining
impressions from the perforated sheets produced by means of the mechanical pens.
These appliances include.
1) A flat or curved frame made in two parts arranged one above the other and
serving to stretch and support the perforated sheet.
2) A fixed or moveable printing table upon which the sheets to be printed are
arranged either by hand or automatically.
3) Stationary inking rollers which when the perforated sheet is drawn beneath
them reproduce the writing or design punctured in the latter upon the sheets to
be printed which are placed under the perforated sheet and between the latter and
the table.
And in order that the said Invention may be perfectly understood I shall now
proceed particularly to describe the same with reference to the accompanying
drawings the same letters of reference indicating corresponding parts in all
corresponding figures.
The description is divided into three parts. The first part relates to the

page_text: construction of mechanical pens proper-The second part describes the supports,
actuating mechanism and other accessories of the said pens and the third part
describes the arrangements for the obtaining of copies or impressions by means of
the perforated sheets produced by the action of the said mechanical pons.
Part 1. The mechanical pens.
The improved pen constructed according to my Invention is provided with a
needle a figures 1 to 14 Sheet 1. contained in a sheath b forming the handle of tho
pen. This sheath is connected at, the upper extremity with a frame carrying a
small grooved pulley A turning upon centre points V V as hereinafter described
and driven by an elastic supporting cord. The motion thus imparted to the
pulley is considerably accelerated when transmitted to the needle a the point of
which portrudes slightly at the conical extremity of the sheath or handle 6 and
serves to produce writing or drawing by puncturing or perforating the paper placed
beneath it thus B C
-The accelerated motion is transmitted directly
to the needle by means of variously shaped cams or their equivalents fixed on the
axis of and turning with the grooved pulley A and acting directly upon the needle
(the upper extremity of which is forked as shown) by the intervention of friction
rollers or otherwise-The extremity of the needle may be provided with two
forked arms passing on opposite sides of the pulley and bearing against two
corresponding cams as illustrated in Figure 1 or with one forked arm only bearing
against a corresponding cam as indicated in Figure 2.
The needle may be operated by cams having an undulating periphery (as
indicated in Figures 3. 4 and 5) acting upon friction rollers e on both sides of the
'pulley as shown in Figures 3 and 4 or on one side of the pulley only as indicated
in Figure 5-The forked extremity of the needle may be guided by means of
guides e¹ attached to or formed on the handle of the pen and acting on both arms of
the fork as shewn in Figure 4 or on one arm only as shown in Figures 5 and 6.
The weight of the needle may be balanced by a spring r figures 3 to 7. which also
serves to keep the friction. rollers in contact with the cams. The elastic supporting
and driving cord is prevented from escaping from the groove in the pulley by
incans of a hoopf figures 1 to 6 or simply by an arm or finger f¹ figure 7.
The sheath 6 of the needle also forms the handle of the pen according to the
arrangement illustrated in figures 1 to 7 but this arrangement renders it necessary
to hold the shaft of the pen vertically or perpendicularly to the paper which is
fatiguing to the operator rendering a certain amount of practice necessary to
enable the pen to be used with advantage and in most cases prevents the
characteristics of the ordinary handwriting from being preserved.
In order to remedy this objection, also common to electric pens, the needle and
its sheath are shortened according to the arrangement illustrated in Figures 8
to 12 and connected to an arm b₁ set at a suitable angle say about forty degrees
with the axis of the needle and provided with a socket for the reception of a
suitable bandle or pen holder b* figure 8 of wood ivory or other materials thus
enabling the pen to be held and used in the same manner as an ordinary writing
pen. This arrangement may be employed in combination with the pens illustrated
in Figures 1 to 7.
The extent to which the point of the needle-a protrudes from the sheath b is
adjusted by shortening or lengthening the latter by means of a telescopic or
equivalent arrangement such as that illustrated in figure 13 the parts of the sheath
being caused to slide telescopically one over the other by means of a screw v
figure 13 or a rack and pinion v¹ figure 14 at the side of the sheath. According to
another and preferable arrangement illustrated in figure 10 one part of the
sheath b is provided with a male screw m engaging with a female screw n on the
other part so that the length of the sheath can be adjusted by simply rotating one
of the parts relatively to the other, means (such as a ratchet or notched ring n² and
pawl nacted on by a spring figures.8 and 9) being provided to prevent-the

page_text: screws from turning accidentally. In order to enable the screw to be turned the
pawl n is disengaged from the ratchet by pressing on a button o on the stem of
the pawl in the arrangement illustrated in Figure 9 or by pulling the button o in
the arrangement represented in figure 8.
The arms of the fork acted on by the cam or cams as hereinbefore described may
be guided by working in recesses p in the sides p¹ of the frame, figures 11 and 12,
which also carry the axis of the pulley.
Part 2-The supports and driving gear of the mechanical pens.
The pens are suspended above the working table as shown in figures 1 and 4
sheet 2 by an elastic cord B passed round the grooved pulley A herein before
described and over an over-head horizontal cylinder A¹ the tension of the said
cord being so adjusted that the hand of the operator is relieved of unnecessary
weight and a slight pressure suffices to draw the cord tight and to bring the needle
of the pen at the same time into contact with the paper.
The said cylinder is caused to rotate by treadles or any suitable means and
drives the said grooved pulley by means of the elastic cord thus imparting a rapid
reciprocating motion to the needle of the pen which is guided over the surface of
the paper by the hand of the operator.
The axis of the cylinder A is supported in a frame C forming part of a standard
or upright S which may be so constructed as to be capable of being fixed to an
ordinary table or may be combined with a specially constructed table as shown in
Figures 1, 2 and 3. The top of the table may be a plain flat top but it is
preferably made in the form of a box D in which the overhead cylinder A and the
standard or upright S may be packed together with the pen when not in use as
shown in figure 2.
The support S, of the overhead cylinder is preferably made in sections of
convenient length connected together at a when the apparatus is in use by any
convenient arrangements such as sockets and set screws as shown in figures 1. 2
and 3 The box forming the top. of the table also serves as a receptacle in which
to pack away the perforated sheets and the printing apparatus hereinafter described
and is preferably hinged to a foot or pillar P on which it stands so as to be capable
of being turned up into a vertical position in order to economise space as shown in
Figure 3.
According to another and very convenient arrangement illustrated in Figures 4.
5 and 6 the vertical sides of the box D (except the side D¹ to which the lid is
hinged) are made in the form of flaps hinged to the bottom and which when
turned down into a horizontal position form extensions of the table When the
pen is in use the box is closed and the sheet to be perforated laid on the top or lid'
of the box. (at D³ figures 1 and 4) but when employed for printing copies the sides
are turned down and the lid turned back (figure 6) so as to form an elevated
shelf or desk for the reception of the blank or printed sheets the pen and its
appurtenances (cylinder. A and upright S) being stowed away at one end of
the box.
When the perforating and printing apparatus are packed away inside the box D
which may be used as an ordinary table and when it is desired to use the apparatus
for writing drawing or producing a perforated sheet from which to print copies the
pen and accessory mechanism is taken out and placed in position as shewn in-
figures 1 and 4.
Part 3. Printing from Sheets perforated by the mechanical
pens
In order to print copies in ink or colour by means of sheets that have been
punctured or perforated by the employment of the apparatus hereinbefore described.
the following devices are employed videlicet.
1. A frame for holding and stretching the perforated sheets.
2. A printing table.
8 An inking roller

page_text: The device for stretching the sheets consists of two rectangular frames A and B
(figures 12 and 3) of equal size one of which is provided with a ridge or tongue a
along two sides capable of entering a corresponding groove or recess 6 in the other
frame. One of the frames is moreover provided with sharp pins c projecting
beyond the ridge or tongue and also with bolts g serving as guides The lower
frame B is placed over an imposing table or block T figure 4 so that its upper edge
is flush with the surface of the table. The perforated sheet is then laid over the
table and lower frame and pressed down over the sharp pins c by means of the
frame A being stretched by the tongues a pressing the border of the sheet into the
grooves b Hinged bolts e connected to the lower frame and provided with thumb
nuts are then caused to engage with suitable projections on the upper frame and
the two frames are pressed firmly together by means of the nuts. The frame A. B.
together with the perforated sheet is then removed from the table T and the shect
that is to receive the impression is laid upon the said table or block. This block
is provided with a projecting ledge T¹ which supports the frames A. Bin such a
position that the top of the block is flush with the division between the said frames
and when the frames and perforated sheet are placed over the blank sheet the latter
is brought directly in contact with the perforated sheet An inking roller R
figures 5 to 11 is then passed over the perforations which allow the ink to penetrate
to the surface of the blank sheet and reproduce thereon the writing or design
punctured in the perforated sheet which with the frames is then removed and the
printed copy exchanged for a fresh blank sheet with which the same operations aro
repeated.
These manipulations demand great care on the part of the operator and in order
to facilitate the work the frame B is provided on its underside with guide bars C
figure 5 extending behind the lower frame B where they are turned upwards then
downwards and secured to the side of the said frame as shewn in the drawing
Two stationary studs or pins c one on each side of the imposing table engage
between these bars and the frame which slides upon the pins c and is thereby
guided to the proper position over the imposing table. When this arrangement is
employed the frames are preferably constructed with three sides only as shewn in
figure 3 in order to enable the frames to be readily removed from the block T by
lifting one end of the former and then sliding them horizontally by hand or
otherwise upon the stationary pins or studs c in the direction of the arrow f
(figure 5) until the frames A B can be tilted up in the position shown in figure 6,
and thus expose the printed sheet remaining on the table T
This arrangement is far preferable to the hinged or jointed arrangements
ordinarily employed in printing apparatus as the danger of straining the perforated
sheet by the resistance of the air suddenly compressed between the table and the
frame is obviated and the said sheet is not liable to drag or shift the printed sheet
when being turned back
The inking may be performed with hand rollers R figures 7 and 8 but is frequently
irregular when this method is adopted so that it is more advantageous to employ
inking rollers supported in stationary bearings and to cause the printing table with
the perforated sheet to slide underneath this roller by means of a rack and pinion
as indicated in figures 5 and 6 or by any other equivalent arrangement which if
desired may be operated by a crank handle or by the treadles or other motor
employed to drive the mechanism connected with the pen.
The supports for the perforated sheet and sheet to be printed may be constructed
in the form of a segment of a hollow cylinder (figure 9) or in the form of a
complete cylinder (figures 10 and 11) the inking roller R being applied either to
the outer surface of such cylinder as shewn in figure 10 or to the inner surface of
the same as shown in Figure 11 and may be combined with any suitable automatic
apparatus for removing or supplying the sheets to be printed.
The inking roller R may be stationary as shown in figure 10 being combined
with a cylindrical table turning on its axis or the table or cylinder may be stationary.

page_text: and the roller caused to describe an arc about the centre of the cylinder as shewn
in figures 9 and 11.
The pressure of the inking rollers R employed in combination with the
horizontally sliding table herein before described work in bearings attached to the
bottom of the box D of the perforating apparatus and their pressure upon the
sheet is regulated by means of a lever and counterweight P figures 12 and 13
oscillating on a fixed centre o
The pressure of the inking rollers R upon the perforated sheet may also be
obtained and controlled by means of a blade spring r figure 14 bearing against a
roller frame m which is guided in a vertical direction between uprights M fixed to
the bottom of the box D. According to the arrangement illustrated in figure 15
the inking roller R receives its supply of ink from a feeding or ductor roller R¹
whose pressure is adjusted in a similar manner by means of springs and which
partakes of a reciprocating motion in the direction of its axis in order to distribute
the ink more uniformly. If preferred the ink may be supplied in the same manner
as in large lithographic presses or by means of a pad or a trough arranged above
the inking roller and moving with the table and supplying ink to the roller which
transfers it to the sheets The inking roller may be dispensed with the ink being
applied directly to the perforated sheet by means of a pad caused to approach or
recede from the table at the proper time being operated automatically by a lever
and a spring or by a treadle placed beneath the table or by other suitable
mechanism.
Having now described and particularly ascertained the nature of the said
Invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider to be novel and original
and therefore claim as the Invention secured to me by the hereinbefore in part
recited Letters Patent is.
First. The improvements in mechanical perforated needle pens as hereinbefore set
forth with reference to sheet 1 and in particular the arrangement in which the
handle of the said pens being set at an angle of about forty degrees with the axis
of the needle enables the operator to hold this pen in the same manner as an
ordinary writing pen all substantially as herein before described and illustrated in
the accompanying Drawings.
Second. The improved supports for the mechanical pen as hereinbefore set forth in
combination with an elastic suspending cord and treadles or other motor mechanism
for imparting motion to the needle and to the carrier or table of the press
substantially as herein before described with reference to sheet 2 of the accompanying
drawings.
Third. The arrangements for supporting and stretching the perforated sheets
produced by the action of the mechanical pens and obtaining inked or colored
impressions or copies therefrom substantially as herein before described with
reference to figures 1 to 11 sheet 3 of the accompanying Drawings.
Fourth. The several improved arrangements for inking the perforated sheets and
in particular the stationary inking rollers in combination with the moveable tables
or cylinders for obtaining copies or impressions of the work produced by the action
of the mechanical pens substantially as herein before described with reference to
figures 12. 13. 14 and 15 sheet 3. of the accompanying drawings
In witness whereof I the said John Henry Johnson have to this my Specification
set my hand and seal this eleventh day of February One thousand eight hundred
and eighty four.
