Improvements in or relating to Printing-machines.
I, FRITZ BRIGHTLING, Compositor, of 147, Gladstone Avenue, Noel Park, Wood
Green, in the County of Middlesex, do hereby declare the nature of this invention
to be as follows:-
This invention relates to printing-machines, its object being, to provide a machine,
adapted for printing, in a newspaper, "stop-press" items in the blank column left
for the purpose, after the remainder of the paper has been printed. The machine
is applicable, however, to other general printing.
It comprises a base plate, with a bracket, in which a reciprocating spindle is
guided; this spindle carries a type box, and as the length of the stroke of the
spindle is preferably constant, a spring is provided between the type-box and
spindle, to enable the former to yield, as may be necessary, owing to variations in
the number of papers, placed in the machine from time to time for printing.
The type-box spindle may be reciprocated by means of a cam wheel or eccentric,
through the intervention of an oscillating lever. Other means may, however, be
employed, for actuating the type-box. The cam wheel or eccentric is mounted
on a shaft, carried in fixed bearings.
An inking apparatus, consisting of rollers, held in a carriage or travelling
frame, is provided. It is reciprocated between the type in the box, above described,
and an inking table, by a lever, preferably actuated from the cam aforesaid. It
is operative on the type surface when the type-box approximates to the position
in its travel in which it is farthest from the printed matter. Springs, in the
carriage or trolley, which may slide on guide rods, cause the ink rollers to bear
against the type, to effect a uniform deposit of ink thereon. The inking table
may be supported from a standard of the framework of the machine, at a suit-
able height, and preferably quite clear of the base which thus presents no
obstacles to the work to be printed. The inking apparatus may consist of a duct
roller, for taking ink from a reservoir or duct, of vibrators, distributors, and of
rollers for inking the type. The ink reservoir is fixed near the outer end of the
travel of the trolley. One side of the reservoir is closed by a revolving roller,
having a ratchet wheel at its end, which is rotated by a pawl, attached to the
trolley, at each approach of the latter. Instead of the trolley sliding on guide
rods under the type, it may be suspended by parallel links; and driven to and
fro by a cam or eccentric, from the aforesaid shaft.
The type-box is preferably made in two or more parts; and provided with a
spring door at one end, to facilitate the insertion and withdrawal of type. The
sides of the box may be type high, to hold the paper in such a way as to secure
clear impressions in printing, and are recessed with slots or grooves, for the recep-
tion of removable plates, which, securely hold the type in the box in the manner
hereinafter described but allow of its ready removal as a whole, or in part. The
type, spaces, and quads, for use in this press, are made with a recess of any con-
venient width and depth, at the back thereof, which admits of their being set on

page_text: a brass"
or "lead", of a similar width and depth; to the brass is affixed, at
both ends, space or quad, of the same body or size, as that of the type used. The
slots or grooves in the box receive plates which lock the spaces or quads at the
ends of the brass aforesaid, and these latter lock the types themselves in place.
The papers are automatically removed as printed, by means of one or more rollers,
formed with two or more ribs or projections, which extend round only a portion of
the circumference; and the rollers are of such diameter, that only or other
convenient proportion, of a revolution of the main, or cam-shaft, to which this
roller is geared, shall be necessary, for the removal of the printed sheets.
This ribbed roller works in conjunction with one or more of similar design,
or plain, as most convenient for the work being produced; or tapes may be used
in conjunction therewith.
Improvements in or relating to Printing-machines.
I, FRITZ BRIGHTLING, Compositor, of 147, Gladstone Avenue, Noel Park, Wood
Green, in the County of Middlesex, 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 relates to printing machines, its object being to provide a
machine adapted for printing, in a newspaper "stop-press" items, in the blank
column left for the purpose, after the remainder of the paper has been printed.
This is preferably accomplished by so constructing the machine that sufficient
space is left upon the base plate between the fixed portion of the machine and the
type-box to allow of the blank space left for the stop press news to be placed
under the latter; and also by so arranging the ink slab and other parts of the
inking apparatus, that the rest of the base plate is entirely clear, thus giving
room for the remainder of the sheet. The machine is applicable however to other
general printing.
It comprises a base plate, with a bracket, in which a reciprocating spindle is
guided; this spindle carries a type box, preferably detachable, and as the length
of the stroke of the spindle is preferably constant, a spring may be provided
between the type box and the spindle, to engage the former to yield, as may be
necessary owing to the variations in the number of papers placed in the machine
from time to time for printing.
The bracket before mentioned preferably carries a shaft which is rotated by
any suitable gearing from a source of power. The type box spindle is connected
to this shaft by any suitable device, such as a cam wheel, or eccentric, or by a
dog-link" in such a manner that the rotary motion of the shaft is converted
into a reciprocating motion of the spindle.
6.
An inking apparatus is provided which may consist of suitable rollers arranged
as hereinafter described so that they travel between the face of the type in the
box, and an ink slab which is preferably attached to the reciprocating portion of
the machine. These rollers may be conveniently mounted on a spring frame
which allows the arms or equivalents which carry it, to adjust their length as
they travel over the surface of the type. The rollers are operative on the type
surface in such a manner that the rollers have traversed the whole of the type,
when the reciprocating spindle is approximately at the top of its stroke, that is
when the type box is farthest from the printed matter.

page_text: An ink duct which may be of any convenient type is provided, fitted with a
ductor roller, which is preferably furnished with a ratchet wheel, rotated by means
of suitable mechanism, for example, by means of a pawl mounted on linked levers,
which are attached to the stationary and reciprocating portions of the frame
respectively.
"
The type box is preferably made in two or more parts; and provided with a
spring door at one end, to facilitate the insertion and withdrawal of the type.
The sides of the box may be type high, or such other convenient height, in order
that they may act as bearers and hold the paper in such a way as to secure
clear impressions in printing; they are recessed with slots or grooves for the
reception of removable slides or plates, which hold the type securely in the box in
the manner hereinafter described, but allow of its ready removal, as a whole, or
in part. The type, spaces and quads for use in this press are made with a recess
brass
of any convenient width and depth, which admits of the insertion of a
or "lead" of similar width and depth; to the brass is affixed at each end a space
or quad of the same body or size as that of the type used, or the piece comprising
the brass with its quads may be formed in one piece of metal. The slots or grooves
in the sides of the type box receive slides or plates as aforesaid which lock the
spaces or quads at the ends of the "brasses", and these slides are themselves kept
in position when the door of the box is shut, by projections formed on the said
door.
б
"
The papers are removed as printed by means of one or more rollers or wheels
formed with one or more ribs or projections, which extend round only a portion of
the circumference; and the rollers or wheels are of such diameter, that only or
other convenient proportion of a revolution is necessary for the removal of the
printed sheets. These ribbed rollers may work in conjunction with one or more
rollers of similar design, or plain, as most convenient for the work being pro-
duced; or tapes may be used in conjunction therewith.

Like letters indicate like parts throughout the drawings.
A ver-
A is a base plate, which may be bolted or fixed in any suitable manner to a
bench or table, and which carries a bracket B provided with bearings or guides B¹
which are joined upon the side remote from the bracket B by a plate B
tical spindle passes through the guides B', being free to reciprocate vertically
therein, but prevented from turning by a suitable projection on the guide B
which engages with a groove or key-way C in the spindle C.
"
The bracket B also carries in suitable bearings B³, a shaft D free to rotate, in a
horizontal plane, approximately central between the guides B¹. This shaft D
has a dise I fixed upon the end adjacent to the spindle C, which disc in provided
with a projecting stud or equivalent D². The stud D2 engages with a horizontal
slot E' formed in a cross piece E which is fixed to, and carried by the reciprocating
dog-
spindle C, & thus the spindle C and shaft D are operatively connected by a
link" which converts the rotary motion of the shaft D into the reciprocating
motion of the spindle C. A sprocket wheel D³ is mounted upon the shaft D and
power is transmitted to it (in the construction illustrated in Fig. 3) by means
of a chain D from a similar wheel Fi upon a crank shaft F, this crank shaft is
and
mounted in standards G and driven by a treadle G¹ in the ordinary manner,
carries two other wheels F2, the use of which is hereinafter described.

page_text: The lower extremity of the spindle C passes through a plate H and is then
fitted with a collar C. Rigidly connected to the plate H by four pillars H³ is
another plate H¹ having two parallel sides bevelled so that they may dovetail
into a recess prepared for them in the top of a type-box J; details of the con-
struction of this type-box are hereinafter given. The spindle C and plates H
and H may be looked upon as forming a carrier for the type box The type box
is thus easily attached to and detached from the carrier, a point of great advan-
tage, for the compositor can quickly remove it from the machine, take it to his
frame and set the type, and then quickly replace it ready for printing. A
spring K is placed between the end of the shaft C and the plate H to allow of a
varying thickness in the pile of papers to be printed. The pressure exerted by
this spring K may conveniently be made adjustable by, for example, screwing
the end of the spindle C and fitting a screw collar thereon-or by an equivalent
device this is, however, for the sake of clearness not shown in the accompanying
drawings.
L is an ink table or slab fastened to a convenient portion of the reciprocating
part of the machine for instance to the top of the plate H'; it is provided at the
top end with an ink duct, of the usual type, shown diagrammatically at L'. The
duct or roller L2 is furnished with a ratchet wheel L3 which is rotated through
a distance equal to one or more teeth, each time the spindle C descends, by means
of a pawl L pivotted on one of two linked levers L5, the extreme ends of the said
levers being hinged, one to the fixed frame 13, and the other to the shaft of the
ductor roller respectively. The usual adjustable knife may be fitted to the ink
duct.
Inking rollers M and distributing rollers M¹ are mounted at each end in a
carrier or trolley M². These carriers are connected by springs N to the arms of
Y-shaped levers O in which they are free to slide. The other member of these
levers is approximately at right angles to a line bisecting the angle of the Y,
that is to say the levers O practically form "bell-cranks and their upper ends
are pivoted at 02 to the lower extremities of links P the tops of which are hinged,
one round the shaft D at the back of the disc D₁ and the other to a stud B in
line with the shaft 1) upon the plate B. A spindle O' passes through the type-
box spindle (near its lower end, and each end of the spindle (1 passes through
one of the bell crank levers O in the angle thereof.
As illustrated in Figure 1 the type-box spindle C is at the lowest part of its
stroke, and the ink rollers are arranged to be at the top limit of their travel, so
that the top distributing roller M is in contact with the ductor roller L2. When
the spindle Crises, the rollers M and M¹ being connected through the links P
and bell cranks will travel down the ink slab L and across the face of the type
in the box J; the lengths of the various levers being so arranged that when the
spindle has reached its highest position the rollers will have traversed the
. whole face of the type. Small collars M are provided on each roller shaft,
which, when the rollers are passing over the face of the type, bear on the bottom
faces of the sides of type box and thus prevent the faces of the rollers being torn
up by the type. When the rollers leave the ink slab L and before they reach
the type box J, auxiliary rollers M³ come into operation running on guides Q
which may be conveniently made of pieces of angle metal bent and fastened to
the type-box J. Similar guides may be fastened to the other end of the type box,
to take the rollers at the extremity of their travel. The inking or distributing
rollers need not be parallel to each other, but may be set at any convenient angle.
Figure 5 illustrates the type-box J in further detail. Two parallel sides are
made with internal slots or grooves J¹ which receive strips J. One end of the
box is furnished with a hinged door J³ fastened by a spring J. The type,
spaces, and quads, R are preferably made with a recess R' in the front or back
thereof and the brasses 'S comprise strips of metal which fit into these recesses,
flush with the back or front of the type, thus saving the space between each line
of type usually taken up by the thickness of the metal forming the "brass" and
"

page_text: forming what may be termed "skeleton" brasses. The brasses may terminate in
quads joined to each end, but preferably they will be formed in one piece. The
ends of the brasses S are so shaped that they are kept in their places by the
slides J. Projecting pieces J5 on the hinged door J³ serve to keep the slides J³
in place. It will thus be seen that by opening the hinged door J³ and with-
drawing the slides J2 any types or brasses may be lifted vertically out and replaced
by others. This constitutes an important advantage over the old method, where
each brass had to be removed by sliding it along and out at the end of the box.
The wheels or rollers F2 (Figs. 1 and 3) are provided with ribs F3 preferably of
rubber or leather, which extend round the wheel only for about of its circum-
Ierence. These ribs project through slots A' in the base plate A and come into
contact with a roller T mounted upon the base plate in adjustable bearings T¹.
When a paper has been printed it is gripped between the roller T and the rib F³,
when it is carried away clear of the machine. If desired another roller similar to
the roller T and placed parallel to it, may be provided and the two rollers con-
nected by tapes in the well known manner to form a guide to prevent the paper
from rising as it is moved away. The length of the rib F³ may conveniently be
approximately equal to that of a newspaper sheet and its position on the wheel Fa
is such that as shown in Fig. 1-it comes into operation just as the type box
spindle is commencing its upward stroke.
The wheels F and D³ are geared one to one, so that the wheel F will make one
revolution for each complete reciprocation of the spindle C.
As illustrated in Fig. 3 the shaft F is the driving shaft and the wheels F2 will
act as flywheels but it is obvious that by mounting another pulley upon the
shaft D that shaft be driven from another source of power, and would drive the
shaft F.
An alternative construction of the mechanism for operating the inking rollers
is shown in Fig. 4, where the arms carrying the inking rollers are mounted upon
a shaft carrying a cog-wheel or pinion U₁. This shaft is carried by the recipro-
cating portion of the machine, and the pinion gears into a rack W fastened to
the stationary portion. It is evident that as the shaft C reciprocates vertically
the pinion will be rotated and the arms and inking rollers will be caused to
travel in a similar manner to that previously described with reference to the other
construction. This alternative construction has the advantage of giving a longer
travel to the inking rollers which is a valuable consideration where a long type
box is necessary.
It is obvious that many modifications may be made in the details of construction.
of machines according to this invention without departing in any way from the
spirit thereof, for example:-The cross-piece E may travel in suitable vertical
slides formed in a plate or frame and fastened to the stationary portion of the
machine; this would give extra rigidity to the reciprocating portion. Again,
the type-box may be carried by two or more spindles or equivalents, which may
be cross braced or strengthened in any convenient manner. This would be an
advantage in machines where a long type-box is used.
It must also be understood that although in the construction of type-box illus-
trated, the locking devices are shown as slides J, sliding in grooves in the sides
of the box, yet if desired the same object may be attained by fitting, for example,
hinged flanges to the side of the type box, or the sides themselves may be hinged
and act as movable flanges.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a printing machine adapted as described, for printing shop-press news,
or similar items the combination of a rising and falling spindle such as C, or other
carrier, and a type-box such as J, whch, for the purpose described is readily
attachable to and detachable from the said carrier.
