We, JOHN HENRY BUXTON, Newspaper Proprietor, DAVIES BRAITHWAITE,
Printer's Engineer, and MARK SMITH, Printer's Engineer all of the "Manchester
Guardian" Offices, Cross Street Manchester in the County of Lancaster 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 in which the impression is made by
means of curved printing surfaces mounted upon an impression cylinder. In such
machines "late news" is sometimes printed by removing a portion of the stereotype
plate and substituting for the removed portion, type or a stereo representing the late
matter but this is an inconvenient process and occupies a considerable amount of
valuable time. The type has also been mounted upon or within an auxiliary cylinder
and printed upon the margin of the newspaper or upon a blank space left or provided
for the purpose but hitherto only a short paragraph or a limited amount of "late
news "could be so printed while the arrangements employed have been more or less.
ineffective. The object of our invention is to enable a larger amount of late news to be
printed by an auxiliary cylinder by simpler and more convenient and effective means
than those hitherto employed. The accompanying drawings with the aid of the
following description will enable our invention to be carried into practical effect.
Similar parts of each of the figures are indicated by similar letters.
Type representing the late news or supplementary matter is secured in a box or
boxes which is or are capable of being secured to an auxiliary printing cylinder.

In each of the figures in which the details are represented A is the main impression
cylinder; B is the auxiliary cylinder; C is the blanket cylinder; E E are inking
rollers; F is the type box; G is the type; H H are the brass rules.
The auxiliary cylinder B has one or more dovetailed recesses and each type box is
formed or constructed to fit into and be held within either of the recesses by being
slided end wise therein. If the type box is made to fit the recess accurately it will
retain its position, but if it is required to obtain greater security, or if the box does
not fit accurately, it may be fastened in the recess by means of any one of various
known devices. Thus, one end of the recess may be closed by an annular plate J in
which dovetailed recesses are formed coincident with the dovetailed recesses in the
auxiliary cylinder. The annular plate is capable of being moved so that the recesses
therein may correspond with the recesses in the auxiliary cylinder, when the type box
may have its dovetail K slided into one of the recesses in the cylinder. The type
box being now in position, the annular plate is moved so that the dovetailed recesses
in the plate and the cylinder respectively do not coincide, as represented in Fig. 1
and the type box will consequently be firmly secured. The annular plate may have
one or two curved slots L through which passes a pin or screw which limits the
motion of the plate, and it may be held in the open or closed position at will by the
spring catch Z engaging with one of two notches in the plate.
The interior of the sides of the type box or the side R is shaped so that they or it
will be radial to the centre of the auxiliary cylinder when the box is in position. The
inside of the bottom of the type box is shaped to the segment of a cylinder concentric
with the auxiliary cylinder. At each end of the interior of the type box there is a
curved slot or recess M into which the projections S upon the ends of the brass
rules H and of the spacing blocks N respectively engage.
One of the brass rules H is placed between each line of type and the nibs or pro-
jections S thereon fit into the curved recesses M so that as long as the brass rules are
parallel with the sides of the box they cannot be lifted.
The brass rules or the types or both of them are shaped so that in cross section
their surfaces are bounded by radiating lines such that when the type is fixed and the
box is in the auxiliary cylinder these lines radiate from the centre of the cylinder.
In Figs. 5 and 8 is shown type having a tapered body which is the arrangement we
prefer to employ. The type and the brass rules may be secured together by means
of a shoulder or chamfer formed upon the upper edge of the body of the type and a
corresponding return or bevelled projection upon the upper edge of the brass rule.
Alternatively, one or more grooves may be formed in the body of the type into
which fit one or more corresponding longitudinal ridges formed upon the brass rules
as shown in Fig. 5 6 8 and 9.
The required matter having been set, and the type having been inserted in the
type box with one of the brass rules between each line of type, one or more of the
spacing blocks is or are inserted if required so as to fill the box which is then closed.
We prefer to construct the type box so that one of its sides R' opens upon a hinge O,
when the ends of the curved recesses M are consequently opened and the projections
upon the brass rules and upon the spacing blocks may be inserted therein. The
inner surface of the side or door R may be lined with sheet indiarubber or with
other soft and yielding material. The door is kept closed by the spring "catch P or

page_text: by a bolt or other similar and suitable device. In case of the device for fastening
the door of the type box projecting beyond and in front of the box a recess such
as Q Fig. 7 is formed on the outside of each box to receive the projecting device in
the neighbouring box when more than oue box is simultaneously used on the auxiliary
cylinder.
The ends and doors R and R' of the type boxes should be made of thin sheet
inetal and preferably of sheet steel so that when two or more boxes are used, the last
line of type in one box may be as close as possible to the first line of type in the
following box.
As represented in the drawings, there is provision for using six type boxes simul-
taneously on the auxiliary cylinder, but any other convenient number may be employed.
The sides and bottoms of the boxes may be formed from a ring or rings of metal
cut into sections, as by this means greater accuracy in the curved recesses M may be
secured.
The shaft of the auxiliary cylinder is carried eccentrically in bearings, one of which
is shown at T Figs. 10 and 11. Each bearing has a plate I secured to it in which
there is a curved slot U through which a bolt passes. By unloosening a nut upon the
bolt, the plate may be turned through a small angle in either direction, when in
consequence of the eccentricity of the bearing, the auxiliary cylinder may be put into
or out of contact with the paper on the impression cylinder.
As shown in the drawings the auxiliary cylinder is geared to make two impressions
for every revolution of the impression cylinder, and this is the arrangement we adopt
when the impression cylinder prints two copies of a newspaper at every revolution.
The gearing and the diameter of the auxiliary cylinder will of course be arranged to
meet any particular requirements.
Having now particularly described and ascertained the nature of our said Inven-
tion, we declare that what we claim is:
1. A type box for use in or upon an auxiliary cylinder in a newspaper printing
machine; constructed and arranged substantially as herein before described and as
illustrated by the accompanying drawings.
2. In an auxiliary cylinder for printing late news in a newspaper printing machine ;
