Improvements in Machines for Making Stereotype Matrices and
Printing Surfaces.
A communication from abroad by VALENTIN LANDSBERG, of Berlin, and PAUL
KÖHLER, of Liegnitz, both in the Kingdom of Prussia, Empire of Germany,
Engineers.
I, WILLIAM Phillips ThompSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object a machine for performing automatically all the
various operations necessary for making or setting up a matrix for printing
purposes.
The advantages of the machine are as follows:-
1. The fingers (or the hand) of the workman have only to press upon the
keys of a keyboard with sufficient power to start the machine for producing each
impression.
2. The driving power for effecting the different movements emanates from a
separate motor.
3. The machine and the motor are automatically connected, for the purpose of
producing the various impressions, by the pressure of the fingers upon the keys.
4. For obtaining a greater accuracy of the printing, the different mechanisms are
so distributed that the parts of the machine by which the pressing down of the stamp
is effected do not materially change their position.
As has been already stated, the movements of the machine for producing the
impressions are made by pressure upon the keys of a keyboard, which serve to set
in action a plunger, which receives a downward pressure upon its upper end.
The types or letter-stamps are placed side by side in a type box. This is fixed
on the type carrier, which receives a horizontal reciprocatory motion below the
plunger by means of a carrier rod. The carrier rod is actuated by a friction
apparatus, which receives its motion from the main driving shaft.
The friction apparatus has the following construction:-
A curved friction lever bears two friction pulleys which are adapted to be pressed
against the upper and lower sides of the carrier rod according as the lever is worked
in either direction. These pulleys rotate in the same direction, and are driven from
a pulley on the main driving shaft. This pulley is connected by a band with a
second pulley, which rotates with a third pulley. The latter communicates its
motion by a band with a fourth pulley, the band being kept taut by a loaded pulley.
This fourth pulley is keyed on the same shaft as the friction pulley. Another
pulley, also keyed on said shaft, is connected by a band with a second band pulley,
keyed on the shaft of the lower friction pulley. Two guide pulleys take the thrust
of the friction pulleys.
Each time the workman presses upon one of the keys, a vertical lever is pushed
to one side by a second lever, which is actuated by any one of the keys. The
vertical lever then releases a horizontal lever, the outer end of which it had
previously held down by a nose or catch. The horizontal lever is now jerked
upwards by a spring and raises the straight end of the curved friction lever by
means of a vertical link connected therewith. The upper friction pulley is thus
pressed down against the carrier rod, and the latter is moved to the right.

page_text: The return movement of the rod, after the stamping has been effected, is accom-
plished by the lower friction pulley, which is driven from the upper friction pulley
by the band aforesaid, and is brought into engagement with the carrier rod when
the straight end of the curved friction lever is depressed.
The motion for effecting the depression of this lever is derived from the secondary
shaft as follows:-
The secondary shaft receives an intermittent motion from the counter shaft. The
latter rotates continuously by gearing with the main driving shaft, and is connected
intermittently with the secondary shaft by a friction clutch device hereinafter
described. By the time that the type-carrier has arrived at the end of its forward
stroke (that is, as soon as the stamp or die corresponding to the depressed key has
been brought into position below the plunger) an inclined nose, on the carrier, has
come in contact with a reed, which has previously been lifted by the depressed key,
and pushes it backwards. The rearward movement of the reed operates to turn an
angle lever upon its axis. The latter lever thus disengages itself from one of a
series of arms, (preferably three) which are mounted upon the secondary shaft
aforesaid, and the latter is now free to rotate. The angle lever, in the above
movement, also operates, by its lateral arm, to depress one end of a rocking lever,
the other end of which, being elevated, releases a clutch lever, by reason of the end
of the rocking lever coming opposite a hole on the clutch lever. The latter, under
the influence of a spring or its equivalent, moves to one side on its pivot and slides
the ring towards the left. This ring is mounted loosely upon a sleeve, which again
is mounted loosely upon the counter shaft, and is permanently connected with the
secondary shaft by an extensible coupling. The movement of the ring towards the
left brings it in contact with a flange fixed on the sleeve, and thus moves the latter
also toward the left, by which means the elastic rings are so compressed between
the said flange and the end of a box fixed on the secondary shaft, that the rotary
motion of the latter is transmitted by friction to the sleeve, and through the
coupling to the secondary shaft. The secondary shaft carries one or more cams
(preferably three) one of which, during the rotation of the shaft, acts to depress a
lever which is so connected by a link with the aforesaid lever that the latter is
depressed into its original position. This lever being connected, as aforesaid, with
the straight end of the friction lever, the latter is also depressed and the upper
friction wheel thereon withdrawn from contact with carrier rod. The same move-
ment also brings the lower friction wheel into contact with the said carrier rod, thus
returning the type carrier to its original position. Or the engagement of the lower
friction wheel with the rod may be effected, either wholly or in part, by a spring or
its equivalent.
The stamping slide, carrying the aforesaid stamping plate and the material to be
stamped, receives a step by step motion, corresponding to the distance apart of the
characters and the size of the latter, by the carrier rod, this being moved by the
friction wheel, keyed on the shaft. The stamping slide is also indirectly (as
described in the following) connected with a friction bar adapted to be engaged on
opposite sides by two friction pulleys (in a similar manner to that above described)
for accomplishing the to and fro movements of the slide. The said pulleys are
mounted upon a pivoted lever.
This lever is actuated as follows:-
As soon as the aforesaid vertical lever permits the horizontal lever to fly
upward, as before described, a lever is drawn upward by a projection on the
link, and its rear end is released from a projection on another lever, which now
flies upwards under the influence of a spring, and, by means of a link, raises
the outer end of the lever carrying the friction wheels and brings the lower one
into action, so as to move the said friction bar towards the left. The friction
wheels are driven continuously from the main driving shaft in a similar manner
to that described with reference to the type carrier. The aforesaid friction bar
acts upon a connecting rod, which is jointed to a lever capable of oscillation
about the axis of a shaft. One of these pawls is for the going on of the slide,

page_text: and the other for the returning motion, the latter motion being necessary if a
word on the end of a line is to be set from behind. One of the pawls is
normally held out of contact with the groove of the friction wheel by means of
a piece, lever, rod and axle. The piece carries two pins, entering into the corre-
sponding slits of the pawls.
The acting pawl is alternately set out of contact with the wheel by lifting through
the thumbs on the arbor, the lever and the rods, and, afterwards, released so that a
turning, by intervals, of the arbor is produced, and, consequently, an intermittent
advancing of the slide.
When the stamping slide has moved to a sufficient distance to the left, it is
arrested by a lever, which regulates the widths of the type as follows :—
The elevated rear end of the depressed key lever enters a more or less deep
incision in a horizontal rod above it. The aforesaid lever, which rests upon or is
connected with the said rod, thus has its opposite end more or less depressed, and,
according to the amount of such depression, comes into contact sooner or later with
a piece on the friction rod. The said piece is furnished with steps, which project
to various distances towards the lever. The stamping slide thus moves for a greater
or less distance.
For reversing the travel of the stamping slide, a fastening lever, a setting lever,
an axle and a lever are employed.
In order to vary the movement of the stamping slide in accordance with the
various distances which may be required between the different words, the following
devices may be employed:
A shaft, worked intermittently from the secondary shaft aforesaid, carries a
pinion which gears with a sliding rack. Directly opposite and parallel to the said
rack is a second rack.
Between the two racks and gearing with both is a second pinion, which is mounted
loosely on a sliding bar lying parallel to the racks.
Any movement in the first named rack in a given direction thus produces a
corresponding movement in the sliding bar in the same direction. The said bar is
connected with an inclined sliding shoe, which is adapted to be thrust to a greater
or less distance below one arm of an angle lever, the other arm of which acts as a
stop for arresting the movement of a piece on the friction bar. Other suitable
mechanism may, however, be employed for the above purpose. In order to permit
of the stamping slide being regulated by hand, suitable mechanism may be
employed.
It
preferable, before stamping the characters or words, to subject the material
to a slight pressure, so that the prominences between the lines and words are made
as high as possible.
For this purpose, a stamp with pulley, a lever and a rod are provided.
The matrices for printing machines with rotating cylinders must receive a
curvature. For stamping vertical lines (for newspapers) there is a stamp or die
sitting with the other stamps or type in the type box, and cut in such a manner that
a stamping of vertical lines in a piece is made possible.
In order to render it possible to make use of the machine for producing the set of
scientific books that usually require complicated corrections, and also in order to
regulate the finishing of every line, a modification of the machine is used.
The matrice is composed (instead of pasteboard) of single small staffs or slices of
metal composition, which are cut by the machine itself, immediately before the
moment of stamping, from long staffs, moved by a pushing arrangement. The
knife serves also for a pushing instrument. As soon as the setter presses upon a
key of the key-board, the long staff, corresponding to the size of the respective
letters, is pushed on. A slice of it is cut off by the knife and moved to the left (of
the machine) where it joins a rail. The slice is now pressed in between the rail
and knife and both the guide walls, in order to be stamped upon in the manner
described above.
As soon as the stamping is finished, the rail moves back automatically, and the

page_text: small slice is pushed on by the knife in order to join the letters of the line, already
prepared.
The long staffs are of five or six different sizes, according to the size of the
letters.
The stamping of one letter being effected, the whole line is stamped in a corre-
sponding way, till the length of one line is reached. The line being complete, the
setter justifies, as usual, by means of spaces. Then the ready line is pushed aside
by the band, the lines being thus formed into pages.
The arrangement of the machine may also be modified in a manner to directly
produce patrices, that is, the ready printing plates, in which case, of course, the
single stamps must be changed in a corresponding manner.
The piece, into which the staff's pass and where they are cut, is of hardened steel,
the knife cutting clear when passing along it. The staffs accurately agree with
corresponding slits of the steel piece.
The movement of the knife is effected by a friction apparatus, similar to the one
already described. Every time a key is pressed down, the friction apparatus is put into
action, the nose becomes free and the knife is moved towards the left. During the
stamping, the knife must be stopped for a moment, which is effected by means of
friction.
During the moments of cutting, an increased pressure is produced by an auxiliary
friction, similar to the arrangement for the movement of the type carrier. It
consists of a lever, friction wheel, roller and spring. The lever is arrested in the
known manner, during the time of rest, and is released by a lever, this being
arrested again by a bar from the shaft of the machine, as before described.

Improvements in Machines for Making Stereotype Matrices and
Printing Surfaces.
A communication from abroad by VALENTIN LANDSBERG and PAUL KÖHLER,
both of Liegnitz, in the Kingdom of Prussia, Empire of Germany, Engineers.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool and 6, Bank Street,
Manchester, both in the County of Lancaster and 323, High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention has for its object a machine for performing automatically all
the various operations necessary for making or setting up a matrix for printing
purposes.
The advantages of the machine are as follows:-
1. The fingers (or the hand) of the workman have only to press upon the keys
of a keyboard with sufficient power to start the machine for producing each
impression.
2. The driving power for effecting the different movements emanates from a
separate motor.
3. The machine and the motor are automatically connected, for the purpose
of producing the various impressions, by the pressure of the fingers upon the keys.
4. For obtaining a greater accuracy of the printing, the different mechanisms are
so distributed that the parts of the machine by which the pressing down of the
stamp is effected do not materially change their position.

Figures 8 and 9 show two modifications useful when working with curved
matrices.
Figures 10, 11, 12 and 13, other modifications.
As has been already stated, the movements of the machine for producing the
impressions are made by pressure upon the keys K' of a keyboard (Figures 1
and 2), which serve to set in action a plunger sta (Figure 1), which receives a
downward pressure upon its upper end.
The types or letter-stamps g (Figure 1) are placed side by side in a type box G.
This is fixed on the type carrier st, which receives a horizontal reciprocatory motion
below the plunger sta by means of a carrier rod z. The carrier rod is actuated by
a friction apparatus, which receives its motion from the main driving shaft A. W.
The friction apparatus has the following construction: -
A curved friction lever H bears two friction pulleys fr fr, Figure 1, which are
adapted to be pressed against the upper and lower sides of the carrier rod z according
as the lever is worked in either direction. These pulleys rotate in the same
direction, and are driven from a pulley A on the main driving shaft A W (see
Figures 1, 2 and 7). The pulley A is connected by a band bd with a pulley A',
which rotates with a pulley A. The latter communicates its motion by a band bd
with a pulley A, the band being kept taut by a loaded pulley. The pulley A³
is keyed on the same shaft as the friction pulley fr. A pulley V, also keyed on
said shaft, is connected by a band with a second band pulley V₁ keyed on the
shaft of the lower friction pulley fr. V V₁ are guide pulleys, which take the
thrust of the friction pulleys fr and f respectively.
Each time the workman presses upon one of the keys, a vertical lever 10
(Figures 1 and 2) is pushed to one side by a second lever which is pivotted at d¹
and is actuated by any one of the keys K. The vertical lever 10 then releases a
horizontal lever h, the outer end of which it had previously held down by a nose or
catch n, Figure 1. The lever is now jerked upwards by a spring f Figure 1 and
raises the straight end of the curved friction lever H by means of a vertical link s
connected therewith. The upper friction pulley fr is thus pressed down against the
carrier rod and the latter is moved to the right.
Ig
The return movement of the rod, after the stamping has been effected, is
accomplished by the lower friction pulley fr', which is driven from the pulley fr
and is brought into engagement with the rod when the straight end of the lever H
is depressed.
The motion for effecting the depression of the lever H is derived from the
secondary shaft W, Figures 1 and 2, as follows:-
The secondary shaft W receives an intermittent motion from the counter shaft W'.
The latter rotates continuously by gearing K, Figures 1 and 6, with the main
driving shaft A W, and is connected intermittently with the secondary shaft W
by a friction clutch device hereinafter described. By the time that the type-
carrier st has arrived at the end of its forward stroke, (that is, as soon as the
stamp or die corresponding to the depressed key has been brought into
position below the plunger, sta) an inclined nose an, Figures 2 and 24, on the
carrier, has come in contact with a reed zr (Figure 2) which has previously been
lifted by the depressed key, and pushes it backwards. The rearward movement of
the reed operates to turn an angle lever w' (Figures 1 and 2) upon its axis. The

page_text: latter lever thus disengages itself from one of a series of arms a (preferably three)
which are mounted upon the secondary shaft W aforesaid, and the latter is now free
to rotate. The angle lever w', in the above movement, also operates, by its
lateral arm, to depress one end of a rocking lever ', the other end of which,
being elevated, releases a clutch lever g (Figure 1) by reason of the end of
the lever coming opposite a hole hg on the clutch lever. The latter, under
the influence of a spring hg2 or its equivalent, moves to one side on its pivot hg³
and slides the ring dri towards the left. The ring dri is mounted loosely upon
a sleeve hw, which again is mounted loosely upon the shaft W', and is per-
manently connected with the shaft W by an extensible coupling ku. The move-
ment of the ring dri towards the left brings it in contact with a Hange dri fixed on
the sleeve ho, and thus moves the latter also toward the left, by which means the
elastic rings fp are so compressed between the said flange and the end of a box Rt
fixed on the shaft W', that the rotary motion of the latter is transmitted by friction
to the sleeve hw, and through the coupling ku to the shaft W. The secondary
shaft carries one or more cams d, Figure 1, (preferably three) one of which,
during the rotation of the shaft, acts to depress a lever h³, Figures 1 and 2, which is
so connected by a link 1, (Figures 1 and 2) with the aforesaid lever h, that the
latter is depressed into its original position. The lever being connected, as afore-
said, with the straight end of the friction lever H, the latter is also depressed and
the upper friction wheel thereon withdrawn from contact with carrier rod z.
The same movement also brings the lower friction wheel f¹ into contact with the
said rod, thus returning the type carrier to its original position. Or the engage-
ment of the lower friction wheel with the rod may be effected either wholly or in
part by a spring fe or its equivalent.
The stamping slide S, (Figures 1 and 4) carrying the stamping plate P and the
material to be stamped, receives a step by step motion, corresponding to the
distance apart of the characters and the size of the latter, by the rod z', this being
moved by the friction wheel F, keyed on the shaft T W. The stamping slide S
is indirectly (as described in the following) connected with a friction bar fit
(Figures 3 and 7) adapted to be engaged on opposite sides by two friction
pulleys ff (in a similar manner to that above described) for accomplishing the
reciprocating movements of the slide. The said pulleys are mounted upon a
lever H which is pivoted at H* (Figure 3).
This lever is actuated as follows:-
As soon as the aforesaid lever 10 (Figures 1 and 2) permits the lever to fly
upward as before described, a lever ar (Figures 1, 2 and 3) is drawn upward by
a projection arl on the lines and its rear end ar² (Figure 2) is released from a pro-
jection ar on the lever ³ (Figures 1 and 3). The latter lever now flies upwards
under the influence of a spring f¹, Figure 3, and, by means of a link sl, (Figures 3
and 7) raises the outer end of the lever H' carrying the friction wheels, and brings
the lower one fr³ into action, so as to move the said friction bar frt towards the left.
The friction wheels are driven continuously from the main driving shaft A. W in a-
similar manner to that described with reference to the type carrier, the motion
being transmitted as shown on Figures 3 and 7 through the wheel A', band dr,
wheels A and A, band dr³, wheels A and V, band dr and wheel V. The afore-
said friction bar frt acts upon a connecting rod le (Figures 3 and 7) which is jointed
to a lever ch capable of oscillation about the axis of a shaft T W. This lever
carries on its side arms two friction pawls kl (Figures 3 and 4) adapted to engage
the grooved friction wheel F and thus to transfer the see-saw motion of the rod frt
to the friction wheel F and the shaft T W on the other side of which pulley Fis
fixed, which moves the rod z' connected with the slide. One of these pawls is for
the forward motion of the slide and the other for the returning motion. The latter
motion is necessary if a word on the end of a line is to be set from behind. One of
the pawls kl is normally held out of contact with the groove of the friction wheel F
by means of the piece ds, lever h' and the axle a³ (Figure 7). The piece ds carries
two pins si, entering into the corresponding slits of the pawls (Figures 3 and 4).
t

page_text: The acting pawl is alternately set out of contact with the wheel by lifting
through the thumbs on the shaft W, the lever hand the rods Z and Ki
(Figures 1, 3 and 4) and afterwards released so that a turning by intervals of the
shaft Tw is produced, and, consequently, an intermittent advancing of the slide.
When the stamping slide has moved to a sufficient distance to the left, it is
arrested by a lever ", which regulates the widths of the type as follows:-
11
The elevated rear end ee of the depressed key lever enters a more or less deep
incision in a horizontal rod Z S (Figures 2 and 2B) above it. The aforesaid
lever h, Figures 2 and 3, which rests upon or is connected with the said rod, thus
has its opposite end more or less depressed, and, according to the amount of such
depression, comes into contact sooner or later with a piece as Figures 2 and 3
on the friction rod frt. The said piece is furnished with steps, which project to
various distances towards the lever. The stamping slide thus moves for a greater
or less distance.
For the purpose of automatically regulating the space of each line, having regard
to the individual spaces which occur between each of the words that go to form
that line, an arrangement provided by which the travel of the car, when a space
is being formed, is automatically varied, this travel becoming smaller when larger
letters, such as m 'w," or when capital letters, are to be printed, and
vice versa.

Referring to Figure 3:
The bar frt carrying the nose piece as also carries another such piece a¹ s,
which latter, when in its normal position, does not come in contact with the
lever h (Figures 2 and 3). This bell-cranked-lever h¹ can turn both on an axle æð
and on an axle a¹.
As soon as the key for the production of a certain word-space is touched, the
inward end of the respective key-lever lifts the rod (Figure 2) thereby turning
the lever H2 (Figures 2 and 3) and consequently also the bell-cranked-lever h¹ on
the axle x. The upper end of h" will now therefore enter into the path of the
nose piece a¹ s:
The space between the nose piece a¹s and the lever ¹, and consequently, also
the travel of the car, will be larger or smaller accordingly as the wedge K
(Figure 3), as hereinafter described, is pushed more or less under the end of the
lever, which is provided with a roller for convenience of travel.
This change in the position of the wedge K is effected in the following manner
and by means of the mechanism represented in Figure 3.
The cog-wheel being acted upon by two racks and is thereby caused first
to turn on its axle, and secondly to move in a horizontal direction. By this latter
motion, the lever 1, connected with cog-wheel by the bar h2 and the rack 214, is
turned and wedge K is moved and placed in its proper position.
The upper rack is connected with the car S by means of the transverse
bar P (Figures 3 and 7) and thereby moves together with such car S.
t'
The movement of the lower rack ¹ depends upon the movement of the shaft W
(Figure 1), which transfers its intermittent motion by means of the pulleys R³ Rº,
(Figures 3 and 6) R' (Figures 3, 6 and 7), screws (Figure 3) worm-wheel Rª and
toothed wheel R (Figures 3 and 7) to the lower rack and the cog wheel -8.
The combined movements or traverse of the two racks 21 and therefore cause
the horizontal movement of the cog wheel and control the position of wedge K.
A modification of the mechanism described is represented in Figure 5. Instead
of the cog-wheel, there is a lever, moved on the one hand by the bar Prv, on
the other one by the shaft W by means of the same pulleys, etcetera, as set
forth.
The travel of the wedge K may also be controlled by hand, for this purpose, the
axis, round which the lever " turns, can be moved by means of the lever h¹³,
Figure 3 the lever being connected with a lever and this one with -a
bandsch, Figure 6.
It is preferable, before stamping the characters or words, to subject the material

page_text: to a slight pressure, so that the raised parts between the lines and words are made
as high as possible.
For this purpose, there is provided the stamp vp (Figure 1) with pulley, the
lever ch and the rod vs.
The matrices for printing machines with rotating cylinders must receive a
curvature, as shown in Figures 8 and 9. For stamping vertical lines (for
newspapers) there is a stamp or die sitting with the other stamps or type in the
type box, and cut in such a manner that a stamping of vertical lines in a piece is
made possible.
In order to render it possible to make use of the machine for producing that class
of scientific books that usually require complicated corrections, and also in order to
regulate the finishing of every line, a modification of the machine, represented by
Figures 10 to 13, is used.
The matrix is composed (instead of pasteboard) of single small staffs or slices of
metal composition, which are cut by the machine itself, immediately before the
moment of stamping, from long staffs, moved by a pushing arrangement, Figure 10.
A is both a knife and a pushing instrument. As soon as the setter presses upon a
key of the key-board, the long staff C", corresponding to the size of the respective
letters, is moved forward, Figure 12. A slice B of it is cut off by the knife A'
and moved to the left (of the machine) where it adjoins a rail R". The slice B is
now pressed in between rail R", knife A' and both the guide walls, in order to be
stamped upon in the manner described above.
As soon as the stamping is finished, R" moves back automatically, and the small
slice is pushed on by A' in order to join the letters of the line, already prepared.
The Figures 10 and 11 show this arrangement at the moment when the stamping
takes place, the Figures 12 and 13 representing when a long staff is pushed on,
ready for being cut. The long staffs 6 Care of 5 or 6 different sizes, according
to the size of the letters, B is the slice to be stamped.
The stamping of one letter being effected, the whole line is stamped in a
corresponding way, till the length of one line is reached. The line being complete,
the setter justifies, as usual, by means of spaces. Then the ready line is pushed
aside, the lines being thus formed into pages.
The arrangement of the machine may also be modified in a manner to directly
produce patrices, that is, the ready printing plates, in which case, of course, the
single stamps must be changed in a corresponding manner.
The piece St", into which the staffs pass and where they are cut, (Figures 10
and 12) is of hardened steel, the knife A¹ cutting clear when passing along it. The
staffs accurately agree with corresponding slits of the steel piece (Figure 13).
The movement of the knife A' is effected by a friction apparatus F", similar to
the one already described. Every time a key is pressed down, the friction apparatus
is put into action, the nose n" becomes free, and A' is moved towards the left.
During the stamping, the knife must be stopped for a moment, which is effected by
means of the friction.
As to the feeding of the metal bars, it may be effected in any known manner, by
a combination of levers or in a similar way.
During the moments of cutting, an increased pressure is produced by an auxiliary
friction, similar to the arrangement for the inovement of the type carrier. It
consists of lever ", friction-wheel frl, roller 1, spring fell. The lever is arrested
in the known manner, during the time of rest and is released by a lever a", this
being arrested again by a bar from the shaft of the machine, as before
described.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
1. A matrix making machine characterised by the combination of the following
inter-operating parts or combinations; namely 1st. a stamp or type carrier moved

page_text: by a motor in such a manner that its movement is arrested as soon as the type to
be printed arrives in position below a stamping or pressing plunger; 2nd. a
stamping slide having fixed to it the surface to be covered with characters, and
capable only of the step-by-step movement required for the printing, such movement
being also produced by the said motor; 3rd. mechanism whereby the step-by-step
movement of the slide may take place either forwards or backwards; 4th. a
shaft W, receiving an intermittent motion from a continuously rotating shaft, and
serving to effect not only the movement of the stamping or pressing plunger but
also to control all the movements of the levers and other mechanisms necessary for
the working of the machine; and, 5th. mechanism whereby all movements of the
machine, which are necessary for the producing of a single letter, are started by
finger-pressure upon a key on a key-board, substantially as described.
2. In a matrix making machine such as described, the mechanism for operating
the type carrier consisting of the lever h, spring f, rods, lever H, spring fe, the
friction pulleys fr, fr, pulleys A', A2, A³, V V, and the friction bar =, the said
levers being arranged with either one or two arms, and each being connected to a
spring in such a manner that the said piece s, when the machine is in a state of
repose, is held in tension, substantially as described.
3. In a matrix making machine such as described, the mechanism for imparting
the requisite step-by-step motion to the stamping, said mechanism consisting of a
lever ar, lever, rod sl, lever H', springs and, friction pulleys fr³ and fr,
