COMPLETE SPECIFICATION.
Process and Apparatus for Printing on Glass, Porcelain and like
Materials.
I, HERMANN GRAUEL of Paulstr. Berlin, in the German Empire, Merchant, do
hereby declare the nature of this invention and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:-
This invention has for object the rapid and easy printing chiefly of label-like and
ornamental designs on objects of glass, porcelain and like materials in one or more.
colours. This is accomplished by means of an apparatus in which by the turning of a
lever or frame, colour is carried by rollers from a pad to a rigid printing plate from
which the matter to be printed or impressed is transferred to an elastic plate in
readiness for the printing operation.
In the accompanying drawing aro shewn different forms of apparatus by which the
process may be performed, Figs. 1 and 2 being respectively a side view and a plan
of a single colour machine in which the operating lever or frame is turned round
one half of a circle or 180°. In Fig. 2 the operating lever is turned down to transfer
an impression from the printing plate to the elastic plate. In Fig. 1 the operating
lever is shewn turned round to the position in which objects are printed from the
elastic plate.
a is the bed plate on which operating lever is mounted on centres c. d is the
part for the reception of the elastic plate e. printing plate or block carrying the
matter or design to be printed. rods connected at one end to band at their other
end carrying rollers which in their to and fro motion supply colour from pad i to
printing plate f.
In using the apparatus lever is turned from the position shewn in Fig. 2 to that
shewn in Fig. 1 thereby moving rollers over printing plate f, then lever b is once
more brought into the position shewn in Fig. 2 whereby elastic plate e is brought to
bear upon and take an impression from the printing plate. Lever b is then turned
back to the position of Fig. 1 in readiness for the printing operation, the printing
plate having at the same time been supplied with colour. Objects are printed
upon by pressing them upon elastic plate e. Their surfaces may be flat or curved.
Fig. 3 is a side view of an apparatus in which the elastic plate e travels through
one quarter of a circle or 90°. Colouring rollers are in connection with lever 6'
through spring rods k. A regulating screw maintains the proper distance between.

Figs. 4 and 5 are respectively a side view and plan of a multiple er lour machine..
In this case the number is three.
fff are the printing plates of which 12 is shewn lying on elastic plate e. Thoy
are arranged to turn on centres c, coming alternately on to bed plate a to receive
from rollers their respective colour and then on to an elastic plate e.
Supposing to be the printing plate for black colour, ¹ for red and
with corresponding pads, i, i, , then in using the apparatus elastic plate e is turned
round to come against whereby it is impressed with the black colour;
turned until it comes against elastic plate e impressing this with the red colour and 12:

In this way three colours may be quickly impressed.
It will be obvious that operating lever may carry either the elastic plate or the

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
1. The process for printing on flat or curved surfaces of glass porcelain and like
materials label-like and ornamental matter in one or more colours consisting in so
operating backwards and forwards a lever or frame carrying a plate of elastic material
that this latter is alternately moved against a printing plate containing the design and
turned over with its elastic and impressed surface ready for printing from, or consisting
in so operating backwards and forwards a lever or frame carrying a rigid printing plate
that this latter is moved against a plate of elastic material and away from the same
leaving the elastic plate impressed and ready for printing from, substantially as
described and shewn."'
2. In carrying out the process referred to in the preceding claim, an arrangement
for obtaining the negativo picture on an elastic plate, comprising, a lever or frame
carrying the elastic plate, operated backwards and forwards, the elastic plate being
brought in contact with a printing plate containing the matter to be printed; and a
colouring roller or rollers in connection with the lever or frame and operated by it
so as to supply colour to the printing plate after the taking of each impression there-
from, substantially as described and shewn.
