CHARLES DAVIES, 57, Cannon Street, Manchester, Plumber, &c., do hereby declare
the nature of this invention to be as follows:-
I firmly fix on cylinder of printing machine, a metal box with dove tail or
V grooves in same, the mounts and heading lines to have corresponding dove tail or
V groves to slide in box and a spring catch attached to box holds the mounts
or heading lines firmly in position; by pressing back the spring catch the mounts
or heading lines can be instantly removed and exchanged. This is a great saving
of time and labour over the old system of fixing the mounts and heading line by
means of set screws.

Improved Way and Means for Fixing Mounts and Heading Lines on
Rotary Printing Machines.
I, CHARLES DAVIES, of 57, Cannon Street, Manchester, in the County of Lancaster,
Plumber, 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 fixing of edition mounts and headlines for newspapers
(and the like) upon the cylinders of rotary printing machines to facilitate the
removal and exchange of such headlines when desired.
Hitherto the mounts and headings have been fixed to the cylinder by means of
set screws and a considerable amount of time was necessarily employed to remove
one and replace it by another, in addition to which the continual removal and
replacing of the set screws was a source of constant wear.
This invention consists essentially in constructing the mount or heading of dove-
tail or other shape to slide into position in conjunction with a box or groove of
corresponding shape affixed to or formed in the cylinder to receive it and a spring
catch or the like to hold it in position.
It will be fully described with reference to the accompanying drawings.

Fig. 9. Plan of another modification.
Fig. 10. Transverse section of same.
I permanently fix a metal change box A into the cylinder C of the printing
machine and I form the mount or heading B so as to slide into position thereon.
The box A is firmly fixed by set screws c or otherwise to the cylinder and is
provided with a dovetail groove a (or other form of retaining groove) and the mount
or heading B is provided on the underside with a projection or slide 6 which slides
into the groove a and is retained thereby. A spring catch D is fitted on one side
of the change box to prevent longitudinal movement of the mount when in
position.
In a modified arrangement (see Figs. 6, 7 and 8) a projecting piece A' may take
the place of the change box and be firmly fixed into the cylinder C and the mount
or heading B may be provided with a groove b¹ in its under side to slide over the
fixed piece A¹ a spring catch 1) retaining it in position as before.
In another modification (see Figs. 9 and 10) a groove c¹ may be cut in the cylinder
and the projection b on the underside of the mount B slide therein.
Instead of dovetail projections they may be of T or other suitable section.
By pressing back the spring catch 1) the mounts or heading lines can be
instantly removed and replaced by another.
By this construction a great saving of time and labour is effected in changing the
mounts which is often very important when for instance it is desired to change to
and issue a special" edition of a newspaper.
"
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is-
-
1. The combination with the cylinder of a rotary printing machine of a change
box affixed thereto and an edition mount or heading line sliding thereon with
a dovetail or other retaining groove and capable of being readily removed and
replaced substantially as described.
2. An edition mount or heading line for rotary printing machines constructed
and arranged substantially as described and shown with reference either to Figs. 1
to 5, Figs. 6 to 8, or Figs. 9 and 10 of the drawings.
