The Invention relates to self-coloring ink stamps, and consists essentially in the
employment of solid types inserted into dove-tail grooves provided in the stamp
block; also in providing the inking device with two or more ink chambers, and
with two or more ink rollers, in order to produce many colored impressions by one
operation with the same stamp; also in replacing the guiding dises hitherto
commonly employed in roller stamps by rims or edges projecting from and forming
one piece with the roller, and utilizing the notch made in the roller for inserting
the types as a means for automatically arresting the motion of the roller stamp
after the impression is completed; also in the application of ink rollers to flat
and to so called self-coloring inkstainps in lieu of the flat ink cushions hitherto
commonly used with that kind of inkstamps.

HENRY PALM, of the Firm Michalecki & Co., of Vienna, Austria Hungary,
1 Burgring 1, Civil Engineers and Patent Agents. "IMPROVEMENTS IN COLORED
IMPRESSION STAMPS." A communication from Mr. Johann Schmidt, Manufacturer,
of Vienna, Austria Hungary.
This Invention relates to hand stamps for producing colored impressions of
words, numerals, monograms, or drawings; it is applicable both to flat stamps
and to roller stamps, and consists,―
1. In the application of metal types stamped solid and inserted into dovetailed
grooves with which the body of the handstamp is provided.
2. In un arrangement for simultaneously producing many-coloured impressions
with a roller stamp or a flat stamp.
3. In the omission of the rolling discs hitherto used in roller stamps, and in
utilizing as a stopping device the recess applied for inserting the types.
4. In the application of coloring rollers to flatstamps, and automatic moisteners
instead of the flat coloring cushions hitherto used for this kind of stamps.
Figs. 1 to 7 of the accompanying Drawings represent a roller stamp provided
with the improvements, Fig. 1 being a side view of the stamp; Fig. 2, a side view
of the same with the wall of casing removed; Fig. 3, a section through line 3, y,
of Fig. 2; and Fig. 4, a longitudinal section through line x, x, of Fig. 1; while
Figs. 5, 6, and 7 are detail views in a much larger scale.
A is the casing enclosing the type roller a, the coloring rollers 61, 63, 63, and the
color receptacles c¹, c, c, and serving as a bearing for the shafts of the said rollers.
Under the type roller the casing is open, and can be closed by the slide & pivoting
on . The type roller a is made of a single piece, and provided at the circum-
ference with as many dove tailed grooves as the set is to havo rows, into which
the types g, h (Figs. 5, 6, 7), are placed with their dove tailed bases; m (Figs. 5
& 6) is a screw which has a conical head, and is screwed in after all types
necessary for the required text have been placed in the roller, and any space
which may remain has been filled up by a blank block o, the screw thus serving
to fix the set of types. The flanges of the type roller project so far as to be
exactly in the same cylindrical surface with the printing surface of the inserted
types, which is absolutely necessary for obtaining a perfect and uniform impression.
The flanges may be serrated, and have the object of securing a perfect contact of
the roller parallel with the printing surface; is a recess in the type roller from
which the various types are inserted in successive rows. Before making the desired
impression or copy the said recess is placed downward, as illustrated by Fig. 2. If
now the roller is run over the printing surface from the left to the right, the hand
which guides the roller feels a small jerk as soon as the recess f arrives at the
coloring roller b, which warns the operator that the impression is completed.
The recess renders thus any special stopping devices unnecessary, and serves
itself as a stop.
The coloring roller b is covered with a soft and elastic material, such as india
rubber, felt, cork, cloth, flannel, or leather, receives color from the receptacle c, and
transmits it by friction upon the types.
The Drawing Figs. 3 and 4 shows three separate color receptacles c which supply
their various colors through the openings n (Fig. 2) to the three color rings or
zones of the coloring rollers, which are separated from each other by discs.
The color receptacles are preferably made of sheet metal, and provided, besides
the above mentioned opening n, with the opening (Figs. 2 and 3) for filling them
with color. Sponges, felt, cotton, or other suitable bodies soaked with coloring

page_text: matter may be placed in the color receptacle, or the color may be filled into the
latter direct, in which case the opening n consists only of a narrow slit or several
small holes arranged in a row. The feed opening u is closed by a screw, a plug,
or a disc 8 of guttapercha or leather pressed on by the inetal plate p and the
screw 2, which passes through the latter, the said disc, and the bottoni of the
casing. The ribs a', a², in the interior of the casing serve to fix the color
receptacles.
Fig. 8 shows a section through a roller stamp in which the color receptacles are
replaced by a roller c' containing the coloring inatter, or a suitable porous body
saturated with coloring matter. This roller is provided with small holes through
which the coloring matter can pass outside, and is covered with permeable elastic
and soft material, such as cork, felt, flannel, cloth, or thin leather.
For supplying coloring matter to this kind of rollers a bottom disc and the
corresponding end of the roller are screw threaded, and so arranged that the disc
can be easily screwed off from the perforated roller, thereby giving access to the
interior of the latter. Instead of this arrangement one or both journals of the roller
may be perforated and closed by a screw, which may be removed for providing the
roller with coloring matter.
By turning the type roller the coloring roller and thereby the roller ² con-
tained in the color receptacle are revolved, the latter roller giving off color to b
which transmits it to a. If a very fine distribution of coloring matter and very
dry copies are required, one or more distributing rollers may be interposed between
the coloring rol band the color receptacle, the construction of these distributing
rollers being si ar to that of the coloring roller b.
The coloring oller bitself however may be used as a color receptacle, in which
case it consists of a hollow sieve cylinder, and is constructed like the roller contained
in the color receptacle just described.
The types to be inserted into the dove tailed grooves of the type roller are
preferably stamped or punched solid from metal.
The dove tailed grooves instead of forming curves may be placed parallel with
the axis of the roller, as shown by Fig. 9. It is also advantageous in flat stamps
to place the types in dove tailed grooves provided in the body of the stump.
The Figures 10 and 11 show how the types may be arranged in flat stamps; for
instance, stamps which are automatically moistened.
The Figures 12 to 19 illustrate an arrangement for coloring flat stamps by
rollers, Fig. 12 being a longitudinal section, Fig. 13 a cross section, and Fig. 14
à plan of a coloring device with color receptacle.
A is a casing of sheet metal or other suitable material, the sides B of which carry
the shaft of the coloring roller b. At the top the casing has an opening m through
which projects the coloring roller; c is the color receptacle which gives off color to b
through the opening n. The coloring roller is constructed as described above for
roller stamps.
The roller may be hollow and serve as a color receptacle, as has been mentioned
in the case of roller stamps, which arrangement dispenses with the color receptacle c.
The side walls B of the casing are continued upward, thus forming a guide for the
stamp, whicli need only be placed on the coloring roller and moved along over the
same. The color receptacle c receives coloring matter through an opening u pro-
vided in the casing, and transmits it to the coloring roller through a narrow slit n.
A sponge, felt, or cotton, or any other suitable porous material may however be
placed in the color receptacle, in which case the slit n is somewhat wider. If it is
desired to distribute the coloring matter finely, and to dry it as much as practicable
before arriving on the coloring roller proper, one or more distributing rollers may
be interposed between the roller in the color receptacle and the coloring roller.
The slit n may be covered with a fabric which is permeable for coloring matter.
The Figures 15 to 17 illustrate a coloring arrangement with color receptacle
roller; c is a hollow roller filled with coloring matter, or with a sponge, felt, or

page_text: cotton steeped in coloring matter, the said roller being a little larger in diameter
than the coloring roller provided with small holes at the circumference, and
covered with cork, felt, india rubber, flannel, cloth, leather, &c., that is to say, with
an elastic and permeable material. The two end-discs are provided with journals
turning in the sides of the casing like the roller c. The roller c is periodically
supplied with color through one of the removeable end discs, or through the hollow
journals. Also with this kind of color receptacles one or more distributing rollers
may be applied.
Figs. 18 and 19 show, partly in plan or side view and partly in section, a roller
coloring appliance for many colored copies, which appliance may also serve as a
letter weight; b1, b2, bs, b, are four coloring rollers separated from each other by
small discs or rings; while c', c, c, c, are the corresponding color receptacles; C is
an ordinary letter weight upon which the casing A is fixed.
Figs. 20, 21; and 22 illustrate the arrangement of a self-moistening stamp with
roller coloring device instead of the cushions hitherto generally used, Fig. 20 being
a side elevation partly in section, Fig. 21 a front view, and Fig. 22, in a larger
scale, a view of the mechanism for turning the stamp. A is the hollow handle
connected with the stamp C in the usual manner; B is a casing having in its front
walls the two slotted guides for the journals of the stamp C; ff, are two triangular
plates attached to the front walls of the casing, and receiving the journals of the
coloring roller b, and of the color receptacle roller c'; D is the stop pin applied to
the inside of the casing; and F, the guide of the stamp, which together cause the
turning of the stamp when the handle is pressed down or released. The turning
in the example shown does not amount to 180°, as is usually the case with self
moisteners provided with color cushions, but only to 90°.
During the first or rectilinear part of the down motion the printing surface of
the stamp slides over the coloring roller b, which is fed by the color receptacle
roller c¹.
The manner in which the turning of the stamp into its working position is
effected is illustrated in Fig. 22, but not claimed as a part of the present Invention.
Instead of the color receptacle roller shown a simple color receptacle may be used,
or the coloring roller may at the same time be a color receptacle. One or more
distributing rollers may also be applied.
In the self moistening stamp shown by the Drawing the printing surface of the
stamp makes a rectilinear motion before the impression takes place. In this case
the coloring roller is fixed and turns only on its own axis when coming in contact
with the coloring surface.
The coloring roller (and with it the color receptacle) may however be made
moveable so as to describe a motion round the point of suspension of the plate f
in which it is supported besides the motion on its own axis. In this case the
printing surface of the stamp need not make a rectilinear motion before printing,
but can receive the coloring matter from the coloring roller during a rotation.
The stamp may obtain a rectilinear motion only, and the coloring roller may
obtain the motion necessary for sliding over the printing surface.
It need hardly be said that also with this method self moisteners may be made
not only for one color but for many colored impressions; it is only necessary to use
two or more coloring rollers and color receptacles instead of one.
Rollerstamps may be made either as separate appliances, or in combination with
pocket knives, tinder boxes, or in the shape of medals, &c.
