page_text: I, ERNEST DE PASS, of 68 Fleet Street, in the City of London, Fellow of the
Institute of Patent Agents, do hereby declare the nature of this invention, to be
as follows:-
This typographic apparatus, termed "Typograph," is useful for taking small
impressions by means of rubber types of special form.
It consists of a frame or box of wood, or other material, which may be of any
size, carrying inside small rods or bars separated from each other by small rubber
plates. In the spaces between the rods or bars the type are placed, and the rods or
bars are screwed up by means of set screws.
The frame or box is furnished with a hinged lid or covering plate, the inner side
of which is faced with a sheet of rubber, cloth, or other material, or with printers'
roller composition or gelatine, of the size of the surface to be printed. On this
sheet is laid the material to be printed, which, by means of small blades, and by
the action of the spring is pressed against the plate. By closing the lid or covering
plate and by pressing lightly on the top of this plate, by means of a lever, the
desired impression is obtained.
The types employed herein are made in india rubber and have large heads of the
form of a T, or hammer. By reason of this form the types do not become reversed
or turned upside down while they are being placed in the spaces or grooves, they
do not become compressed, neither do they become crooked, and as their heads
rest on the rectilinear plane formed by the rods or bars they give an extremely
clean impression.
Another important part of this invention is the manner of inking the types, and
the mechanism provided therefor.
For this purpose I employ two rollers covered with cloth, or with an elastic
composition, such as glue, gelatine, and of an aniline colour. These rollers are
placed parallel and with pivots in a bottomless box, which by means of small bars
bent at an obtuse angle, is connected to the lid or covering plate in such a way

page_text: that in opening and closing this latter, the rollers with their box are conducted and
slide with a slight pressure over the types. The small box is guided by metal
bands which at the same time serve to prevent the rods or bars from leaving their
position.
The roller box may be removed from the frame, and to re-ink the rollers (which
need only take place after a sufficiently large quantity of copies have been printed)
a pad saturated with colour is used, over which they are caused to pass. The
gelatine rollers need not be inked, the gelatine itself contains the aniline colours
with glycerine, which enables the rollers to communicate sufficient colour to the
types. When rollers of this kind have ceased to give colour, it is then necessary
to replace them by new ones.

page_text: I, ERNEST DE PASS, of 68 Fleet Street, in the city of London, Fellow of the
Institute of Patent Agents, 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, reference being had to the accom-
panying drawings and to the letters and figures marked thereon, that is to say :-
This typographic apparatus, termed " Typograph," is used for taking small
impressions by means of rubber types of special form, hereinafter described.
The construction of the apparatus and the form of the type will be readily
understood on reference to the drawings in which Fig. 1, represents the apparatus
closed, and Fig. 2, half open.
A, is a frame or box of wood, or other suitable material, and which may be of
any size carrying inside small rods or bars a, separated from each other by small
rubber plates. In the spaces between these rods or bars the types are placed, and
the rods or bars are then screwed up by means of two set-screws C. In apparatus
of larger size, more than two set screws are used.
The frame A, is furnished with a binged covering plate B, the inner side of
which is faced with a sheet D, of rubber, cloth, or gelatine, of the size of the
surface to be printed. On this sheet of rubber is laid the material to be printed
on, which by means of small blades f. f, and the action of the spring g, is pressed
against the plate D. By closing the covering plate B, and by pressing lightly on
the top of this plate, by means of the lever G, the desired impression is obtained.
The types employed in this apparatus are made of india rubber and have a wide
head i, of the form of a T, or of a hammer, (see fig. 3). By reason of this form,
the types do not become reversed or turned upside down whilst they are being
placed in the spaces or grooves, they do not become compressed neither do they
come in a wrong position, and as their heads rest upon the rectilinear plane, formed
by the rods a, they give an extremely clean impression.
Another important part of this Invention is the manner of inking the types, and
the mechanism provided therefor. For this purpose I employ two rollers o, o,
covered with cloth, or made of an elastic composition of gelatine, glycerine, and of
an aniline colour. These rollers are placed parallel, and with pivots, in a bottomless
box p, which, by means of small bars r, bent at an obtuse angle, is connected to
the covering plate B, in such a manner that, in opening and closing this latter, the
rollers with their box are conducted and slide with a slight pressure over the types.
The small box p, is guided by the metal strips 8, which, at the same time, serve to
prevent the rods a, from leaving their position.
The roller box p, may be removed from the frame, and to re-ink the rollers (an
operation which need only take place after a sufficiently large quantity of copies
has been obtained) a pad saturated with colour is used, over which they are caused
to pass. The gelatine rollers need not be inked, the gelatine itself contains the

page_text: aniline colour with glycerine which enables the rollers to communicate sufficient
colour to the types. When rollers of this kind have ceased to give colour it is
then necessary to replace them by new ones.
Having now described the Invention and in what manner the same may be
carried into practice I claim, as communicated to me by my foreign correspondent:
1. The construction of a typographic apparatus, termed "Typograph," consisting
of a frame A, with a covering plate B, in combination with the mechanism used
for inking the types, consisting of rollers o, o, mounted in the box p, and passing
over the types when the covering plate B, is being opened or closed, substantially
as herein described and as shewn in the drawings.
2. The construction of the india rubber types with wide and projecting heads i,
in the form of a T, or of a hammer, the purpose of same being to allow the types
to be set firmly and thus to produce a very clean impression, as described and
shewn.
