I, THOMAS DAVID WORRALL of No. 37, Pyrland Road Highbury New Park
London N. and by profession a Physician, do hereby declare the nature of this
invention to be as follows :-
My invention consists in an improved Printing Press, by means of which I print
with paper, silk or other suitable fabric which has been first prepared by saturating
the same with aniline dyes, or other pigments or inks, the same being used as a
substitute for ordinary printers ink, and the press being so constructed, that it contains
rolls for carrying one or more sheets of the prepared paper over the face of the type
between the said type and the paper to be printed, and also in a single or multiple fly
provided with reels or rollers by means of which strips of paper, or ribbons of any
suitable fabric, saturated in pigments or inks of two or more colors, may be brought
down over the face of the type, so as to print one or more sheets in two or more
colors at one and the same impression.
My improvement consists also in a movable platen or cylinder and movable type
holder so constructed that they may be moved at pleasure over any part of the bed of
the press, so as to print from any part of a type form, or several forms, without
simultaneously printing any other part thereof, thus enabling me to print on different
parts of a sheet of paper, and in different colors simultaneously, or consecutively and
also to enable me to print with ordinary printers ink, as a base, and simultaneously
with colors produced by the ribbons being brought over the type after being inked,
and thus printing in many colors at one impression:

I THOMAS DAVID WORRALL of No. 37 Pyrland Road Highbury New Park
London N. and by Profession a Physician do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention consists in the construction of improved printing presses with a
moveable platen and lever and certain adjustments by means of which I am enabled
by the use of saturated paper silk or other suitable fabrics to print with aniline dyes
or other, pigments and to do so consecutively or simultaneously in different colors.
My main improvement consists in the construction of a printing press with a platen
horizontally moveable along a cylindrical bar and so arranged that it can be pressed
down at any part of the bed of the press by means of a lever also moveable liorizon-
tally along an opposite parallel bar.
the
I first make a press with a bed. At each side of that I fix a polished bar of steel
or of other metal. Upon one bar I fit a platen so arranged that it will both slide
along and swing upon this polished bar, and so adjusted that it will face upon any
part of the bed of the press to which it may be placed opposite. The platen may
be made a third or a fourth or any other proportion of the length of the bed
press but it will be as wide as the bed of the press. It will swing upon the polished
bar referred to so that it can be brought down upon any forme of type that may be
set up in the bed of the press. Upon the opposite and parallel polished bar I fit a
lever having a friction roller and so arranged that the lever will slide and swing
along the bar and thus it can at any time be brought opposite the moveable platen to
press down the same.
The result is that I am enabled to set up two or three or more different forms of
typo in the bed of the press each of which is not to be wider than the face of the
platen. These forms of type may be allowed to stand as long as required and need
at no time be removed.
When it is desired to print either the one or the other the platen will be slid along
the bar until it is opposite to the forme to be printed and it will then be brought
down upon that form of type from which it is desired to print both those that lie
loose in the bed of the press and that which is capable of being adjusted as described
and upon which it will be pressed in the usual way by means of the said moveable
lever.
By the aid of this arrangement of the moveable platen and lever I am enabled to
print upon different parts of the same sheet of paper and in as many different colors
simultaneously or consecutively. Instead of a moveable platen the same result can
be obtained by constructing in different presses moveable and divisional cylinders.
Although this improvement of a moveable platen can be used with ordinary
printers ink
my invention consists also in combining its use with aniline dyes or other

page_text: suitable pigments which may be applied by means of pads or rollers upon the face
of the type or may be contained in a saturated material which is itself laid over the
type.
The saturated material may consist of prepared paper silk or other similar fabrics
of a suitable character.
In order to practically carry out the process of printing with a moveable platen
and the saturated material I attach to my press at each end a metallic rod or winder.
I fasten a strip of saturated material to each of these rods or winders by means of
slits and in this way I am enabled to have at each end of my press a roll of the
saturated material which can be constantly changed by simply turning the winder.
The process of printing with this saturated or prepared material consists in passing
it over the face of the forme of the type in the bed of the press and then by the
aid of the moveable platen and lever I am enabled to print off any particular form
that I may desire. Besides this arrangement of winders for the purpose of carrying
this saturated printing material I also construct by fixing upon pivots at the head
of my press a moveable frame somewhat longer than the press itself and containing
at the fixed end several small rollers. The object of these rollers is to fix upon them
strips of paper silk &c. of various colors also saturated as described. By means of
this frame so moving upon pivots at the head of my press I am enabled if desirable
to bend over the bed of the press the several strips of various colors of the saturated
material it contains or carries at the same time and by then using the platen and
lever and the press I am enabled in fact to print three or four or more colors simul-
taneously by single pressure. I also construct at end of press a frame carrying two
three or more rods or winders each holding saturated paper or other material of the
samo or different color I am thus enabled by laying upon the face of the type these
various saturated materials interleaved with the paper upon which the impression is
to be taken to obtain at a single pressure as many impressions as there are different
sheets of such saturated material and of as many different colors.
Having now practically described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is
1. I claim as new the use and combination of a moveable and divisional platen
with a moveable lever both swinging and sliding as above described.
2. I also claim the combination of a moveable or divisional platen and lever
together with the use of analine dyes or other pigments for the purpose of printing
whether applied by means of pads or rollers and upon saturated material as arranged
upon the rods or winders as described and also the arrangement by which two,
three, or more impressions of the type can be obtained at a single pressure.
Dated this Fourteenth day of June 1888.
