Improvements in Printing Machines.
We, WILLIAM SILVER FOORD, WILLIAM WATSON FOORD and JOHN KILBY
FOORD, all of the Firm of Dryden & Foord, of Kinaston Works, Oakley Street,
Lambeth, in the County of Surrey, Engineers, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in printing machines and has for its
object to enable single-cylinder machines to be so constructed that they can be
used either as perfecting machines or as single-cylinder machines.
According to our invention we extend the table of the single-cylinder printing
machine and provide it with a second impression cylinder, inking roller and other
necessary parts required for printing. This second impression cylinder is so
arranged relatively to the ordinary impression cylinder that as the printed sheets
successively leave this cylinder they are conducted by means of appropriately
arranged tapes or other suitable appliances to a laying-on board situated in
proximity to the second cylinder by which the opposite side of each sheet is printed
on. The sheets thus printed on are conducted from the second cylinder by any
suitable means and delivered from the machine in the usual manner by flyers
situated in contiguity to the last mentioned cylinder.
We prefer not to dispense with the taking-off device and flyers with which the
ordinary impression cylinder is provided, but we so arrange these parts that they
can be thrown into or out of action according as the printing machine is to be
used as two ordinary single-cylinder machines or as a perfecting machine.
In some cases where sufficient space is available we may accomplish our purpose
by combining two of the ordinary single-cylinder machines, one of said machines
being used to print on one side of the sheets and the other machine to print on the
other side. Intermediate devices similar to those above described would then be
employed for conducting the sheets from the first to the second machine.
A printing machine constructed in accordance with our invention is more con-
venient by reason of its capability of working either as two single-cylinder
machines or as a single perfecting machine according to the requirements of the
user and in this way considerable saving in expense is also effected.

Improvements in Printing Machines.
We, WILLIAM SILVER FOORD, WILLIAM WATSON FOORD, and JOHN KILBY
FOORD, all of the Firm of Dryden & Foord, of Kinaston Works, Oakley Street,
Lambeth, in the County of Surrey, Engineers, 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 of the kind or class known as stop-

page_text: cylinder or wharfedale machines and has for its object to so provide that one-
machine can be used either as two ordinary single-cylinder machines or as a
perfecting machine.
According to our invention we extend the table of a single-cylinder printing
machine and provide it with a second impression cylinder, inking rollers and other
parts required for printing. As the printed sheets successively leave the first
cylinder they are reversed and conducted by means of appropriately arranged
tapes or other suitable appliances to a laying-on board situated in proximity to the
second cylinder and are thence removed by the gripping devices of the second
cylinder and passed over the second type bed. The sheets thus printed on both
sides are conducted from the second cylinder by any suitable means and delivered
from the machine in the usual manner by flyers situated in contiguity to the last
mentioned cylinder.
We so arrange that the taking-off device and flyers working in connection with
the first impression cylinder can be thrown into or out of action according as the
printing machine is to be used as two ordinary single-cylinder machines or as a
perfecting machine. The devices for conducting the sheets from the first to the
second impression cylinders can also be thrown in and out of action as required.
In the accompanying drawing we have shown in side elevation a portion of a
machine constructed according to our invention.
A is the bed of the machine, B is the first impression cylinder, C is the laying-on
board, E is the flyer drum, F is the flyer for removing the sheets when the
machine is used as a single-machine. G is the second impression cylinder, H is the
laying on board therefor, and J is the flyer drum, and K the flyers for removing
the sheets from said second cylinder.
.to
To enable the machine to be used as a perfecting machine we provide an
extra take-off drum L provided with grippers contiguous to the flyer drum E
and we support the said drum L in bearing blocks L' that can be raised
and lowered in guides M by screws M₁ or other suitable means in order to
put the drum in or out of action as may be required. When the drum L
is lowered it serves to take the sheets from the drum E and to deliver them
a system of tapes N, N1 or other equivalent apparatus by which the
sheets are conducted to the laying-on board H ready for the second impression
cylinder G. By the arrangement of take off drums and tapes as shown the sheets
are delivered to the board H with the printed side uppermost so that after the
sheets have been passed around the second impression cylinder they will be printed
on both sides. The flyer F may be thrown out of action when the machine is
being used as a perfecting machine as it is only required when the machine is
being used for printing on one side of the paper only in which case the drum Ļ
is raised so as to allow the sheets on the drum E to pass to the flyer F. The
raising and lowering of the drum L to bring it out of or into action can be effected
in a few seconds.
In some cases where sufficient space is available we may accomplish our purpose
by combining two ordinary single-cylinder machines, one of said machines being
used to print on one side of the sheets and the other machine to print on the other
side, intermediate devices similar to those above described being employed for
conducting the sheets from the first to the second machine.
A printing machine constructed in accordance with our invention is more con-
venient by reason of its capability of working either as two single-cylinder machines
or as a perfecting machine according to the requirements of the user and in this
way considerable saving in expense is also effected. Moreover it occupies less
floor space than two separate aud independent machines.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. A printing machine having two impression cylinders of the stop-cylinder or

page_text: wharfedale type so combined and constructed with intermediate transferring
devices that the said machine can be used as a perfecting machine or as two
single-cylinder machines, substantially as described.
2. A printing machine of the stop-cylinder or wharfedale type furnished with
means substantially as described for reversing the printed sheets and delivering
them to another machine or to another impression cylinder on the same machine,
for the purpose specified.
°
3. A printing machine constructed substantially as described with reference to
the accompanying drawing and operating as, and for the purposes, specified.
