in Printing Presses and similar Machines for Printing Indepen-
dently of the Ink Used by the Press or Machine itself.
We ALBERT PARKER HANSON of Milwaukee, W.S. U.S.A. Journalist and CARL
PORSTRAND, of Raadhusstraede 5 Copenhagen, Denmark, Merchant 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 :—
The use of the instrument here described depends chiefly upon the difference in
hardness, which exists between the inking rollers and the cylinder or platen, or their
equivalents of printing-presses and similar machines.
The instrument may be used independently of any type or other printing "form,"
but is designed with an especial view to its adaptability as a part of any ordinary
"form."
"
The main feature of the instrument or mechanism may be described by stating
that, where used in a "form "-one or more of its movable parts are held projected
above or beyond the surface of the surrounding
"form by a spring or its
equivalent as, for example, weighted levers-acting virtually from beneath. Upon
these parts, the inking roller or its equivalent-as, for example, the endless cloth belt
in some wall-paper machines-being soft and yielding, has no effect other than that
of inking them.
The cylinder or platen or its equivalent-on the other hand, exerts sufficient
pressure upon this projecting part, or parts,-to force it down or inward, nearly or
quite even with the rest of the form and thus causes a printing surface, previously
or simultaneously supplied with ink from a source of its own, to rise or move
sufficiently that its device may be imprinted upon the paper or surface with which
it comes in contact.
It will thus be seen that, by the use of this instrument or mechanism, a form can
be printed in color or with other variations-as for example, a varying device upon
successive impressions-by being run once through an ordinary press.
Several impressions or an especially constructed press are thus rendered unnecessary
in many kinds of color or variable work.

page_text: In the accompanying drawings, executed upon an enlarged scale, various forms of
an instrument or mechanism of the kind indicated are represented, G, being always
the projecting part while the line, cc, represents the comparative height of type or
thickness of form."
Sheet 1. One construction.
Fig. 1. represents the instrument as seen from above. Fig. 2. a vertical section
through, a a, Fig. 3 a vertical section of case, D, end inking pad, N L, through the
line, bb, the other part remaining intact and Fig. 4 a top view of the bottom
plate, F, with parts connected therewith.
A is a rubber roller, carried by means of the extending ends of its iron core, CC,
between the upright arms of the frame, B, which moves up and down in guide-ways
formed in the case, D. Near either end of the case, D, and projecting a proper
distance above its surface is a peg, G, having a hend, T, on its lower end and held
pushed upwards from below by the spring, K. The levers, H H,-pivoted on the
projections, JJ, from the bottom plate, F, by means of the rivets, I I,-serve to lift
the frame, B, by means of its centre pin, V, when pressed down respectively by, G
and G. The springs K K, acting under the levers, HH, hold the pegs, G G, pressed
upwards with such force that an inking roller being soft and yielding-cannot press
them down.
The springs, however, yield under the pressure of the cylinder or platen and thus
the frame, B, is raised, so that the roller, A, comes in contact with the paper or the
surface, which presses upon, G G. Upon the pressure being removed the springs, KK,
acting under the levers, H H, force the pegs, G G, upward or outward and the
frame, B, with the roller, A, downward or inward.
A, when not forced upward, rests upon an inking pad, N, formed of saturated felt
contained in the case, L. The case, L, is held in position by the four projec-
tions, JP J P, from the bottom plate, F, and the four rivets, M M M M, and, being
raised along the centre line of its bottom, permits of the upward and downward
motion of the parts beneath. Upon one end of, C, the iron core of, A, is placed_a
toothed wheel, Q, which, acted upon by a spring catch, S, fastened to the case, D,
causes the roller, A, to revolve on its upward movement and thus present a freshly
inked surface to the paper or surface upon which it is to print.
Sheet II. another construction.
Fig. 1, as seen from above, with a part of the top plate of the case D₁, removed.
Fig. 2 a vertical section through line, a a, Fig. 3 a vertical section through bb, the
inking pad, N¹, and part of the roller, A¹, being removed, and Fig. 4-reduced-
showing parts G¹ Bi II' and S'.
In this form the roller, A', has three printing surfaces, the device being formed
directly upon these surfaces or forined separately-as in rubber-and attatched to
them, as shown in section by ZZ¹ Z', in Fig. 2.
The frame, B¹, carrying the roller, A', and the plate, G¹, are movably supported
and guided upon the side of the case, D', by the guiding pins, X1 X1, fastened in
their proper positions. The levers, H'H', are supported by their respective pivots ;
II', in such a position that, while one arm acts upon the frame, B', from below, the
other aro is acted upon by the plate, G¹, from above. In an opening in the frame, B',
is placed a spring, K', with its ends resting upon the rivets, Y¹, and its centre
pressing downwards upon, B. Pressure being exerted upon the upper edge of, G³,
sufficient to overcome the power of the spring, K1, the frame, B₁, with the roller, A',
is forced upward and one of the surfaces, Z', is presented for printing, having already
been supplied with ink from the pad, N¹. The roller, A', turns of a revolution,-
always in the same direction-during both its upward and downward movement and
thus the three faces are presented in rotation, to the inking pad and to the surface
to be printed.
The toothed wheel, Q¹, has three or any multiple of three teeth, and is fastened
upon an extension of the journal or bearing, C. S¹, is a double spring catch
fastened to the case, D', and so acting upon, Q', that one arm turns the roller, A¹,
upon its upward movement, while the other arm turns it during its downward motion.

page_text: The inking pad, N', may, for example, be of any saturated substance or may be an
especially prepared gelatinous mass.
Sheet III. a third construction.
Fig. 1, as seen from above with parts of the upper plate, D., and stereotype, or
other printing device, C, supported therean, removed. Fig. 2 view from side, with
the side of case, D³, together with one lever, H³, ratched, "Q" S, and part of side of
ink reservoir, L³, removed. Fig. 3, section of case, levers and inking pad through
line, a a, the roller, A², and connected parts remaining intact.
This form is designed for use in Victoria, or like, presses, or where ever the
printing form is curved or encircles a cylinder. Here a part of the surface is covered
by a stereotype or other printing device, O³, an idea, which, of course, may be applied
to any form of the instrument, flat or curved, wherever circumstances render it
desirable.
The roller, A², is, in this instance, carried between projecting arms of a broad flat
spring, B2, which is made fast, at one end to the under side of the top plate of the
case, D. The levers, H2, H₂, are pivoted by the rivets, II, to the sides of the
case D³, and, while one arm rests under the plate, G2, the other rests under the broad
spring, B. G is movably supported upon, D³, by X³, and upon its being pressed
down or inward the spring, B, hearing the roller, A³, is forced upward, presenting a
surface for printing. The inking-pad, N³, may be supplied from a reservoir, L³,
containing ink, w³, in a fluid or semi-fluid state.
At the end or ends of the roller, A³, may be applied a ratchet movement indicated
by Q, S, and similar to those already described, for turning the roller, A³, in order to
renew the ink upon its surface.
Only one end of the instrument is represented in this drawing. The length may
be extended according to desire and another, printing roller, A³, with connected parts,
may be adjusted at the other end.
Sheet IV. a fourth construction.
Fig. 1 seen from above with portions of some of the various part removed. Fig. 2,
seen from the side with portions of the side of case, D³, and ink reservoir, L³, one
lever H³, spring, M³, and ratchet Q³, S³, removed.
Fig. 3 seen from the end with end plate of case, D³, and ratchets Q3 S³, removed
and levers, H³ H³, shown in section Fig. 4 shows in an enlarged form the ratchet Q³ S³,
for turning the roller, Js, and thus altering the position of the inked ribbon, C³. The
printing device being upon the upper surface of, A³ A³, is firmly held upon, or may
form a part of the broad spring, B³, which is affixed to the under side of the top plate
of the case, D³, see Fig. 2.
The levers, H³ H³, serve to raise the free end of the spring B³, upon sufficient
pressure being exerted upon the upper edge of, G³, G. being movably supported upon
the end plate of the case, D³, by means of the pins X X³. C³ is an endless ribbon,
constantly supplied with ink from the reservoir, N³ L³, and movable in the direction
of the arrows, about the rollers, J³ K³ and T³, the surface of, A³, being sufficiently
smooth to allow the ribbon to slide over it, and roller T³, being supported by
springs M from the sides of the case D³, in such manner that the ribbon, C³, is held
sufficiently tant.
11 are the pivots upon which the-levers H H turn.
G being now forced down, B³, is forced upward. The roller, J³, offering great
friction to the ribbon, C³, and being held from turning backward by a spring catch
upon the roller, K³, holds that part of, C³, stationary, while the light springs, M³ M³,
holding the roller, T, give and allow the ribbon, Cs, to slide upon the face of A³, as
it goes up. The pressure of A³, upon the inked ribbon is sufficient to imprint the
design found upon the surface of, A', upon the paper with which the ribbon comes in
contact in the same manner as is used in many type writers.
When the pressure is removed from G B with its corresponding arm of the
lever, H³, sinks, while the opposite arm of H³, rises and by a imechanism shown in
Fig. the roller Jis turned slightly and moves the ribbon C³ a little forward in the
direction of the arrows.

page_text: .
Where necessary another roller may be adjusted against the roller J as shown in
Fig. 5 this giving J a better hold upon the ribbon C. As the ribbon C³ passes
about the roller, K³, it is brought in contact with the saturated inking pad, N³, which
in turn may be supplied with ink from the reservoir behind it.
C³ is a printing device affixed to the upper surface of D³ and of course will be
printed the same as an ordinary type or printing form in the ordinary way.
In Fig. 4, Q is the toothed wheel which is affixed, one at each end of the roller, J..
Nearly surrounding this wheel is a slight spring S with a tooth fitting into one of
the teeth, Qand two parallel projections outward which pass one on either side of a
pin Ps fastened into the lever H³.
On the downward motion of this arm of, H³, the spring allows its tooth to slide
over the teeth of, Q³, and catch in the next one lower down, when upon being raised
again, the pin, P³, turns the wheel, Q³, and thus the roller, J³, a part of a revolution
in the direction of the arrows as shown in Fig. 2 and 5.
It is understood that this instrument or mechanism is designed to be used wherever
type or printing forms are or can be used or wherever circumstances render it
applicable. A great variety of form and construction is thus involved, only some of
which are given as illustrations.
In some kinds of color work, for example, it is desirable to remove the parts, G,
to some distance from the printing surface, A, this involving a change in form or a
combination of levers or other parts.
The upper surfaces of the case, D, may be lower than the type or surrounding form
and thus leave a blank upon the surface printed or it may be of equal height with the
type and, like the upper surfaces of the parts, G, supplied with any device for printing
in the same manner as ordinary type or printing surfaces.
The roller or printing surface, A, may be carried by the levers, H, themselves and
a spring or springs, K,-sheets 1 and 2-rendered unnecessary by attaching weights
to the levers, sufficiently heavy to enable, G, to resist the pressure of the inking
rollers or parts.
The inking pads or apparatus may be placed directly underneath the roller or
part, A, or in any other position circumstances may require and may be supplied with
one or several kinds or colors of ink.
The part, A, bearing the printing device or devices may have any form as for
example that of a cylinder, a prism or a single plate and may be firmly fixed on the
movable part, B,-as on sheet IV. or may revolve about an axis, either in one direction
or backwards and forwards, as circumstances may demand, in order that the ink on
its surface or surfaces be renewed. The surfaces of, A, may be supplied, all with the
same or each with a different device for printing.
It is not necessary that the movable parts, G, project above or beyond the surface
of the surrounding form as, by underlaying upon the cylinder, these parts may be
reached even though they do not thus project.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what
we claim is:
1. An instrument or mechanism for use in printing presses and similar machines-
independently of, in connection with or incorporated in, a printing form or device,-
for printing independently of the ink used by the press or machine itself: such
instrument or mechanism being so constructed that certain of its movable parts-
as, G-resist the comparatively slight pressure exerted upon them by the inking roller
or its equivalent, but yield under the firmer pressure of the printing cylinder or its
equivalent and cause a printing surface-as A,-supplied with ink from a special
source as, N, to rise or advance from a receded position and come in contact with
the paper or surface to be printed.
2. The use in such instruments or mechanism, or in instruments or mechanism
similar thereto, of movable parts-as, G, held forced upward or outward by springs-
as K, sheets 1—2,— or other devices with such force as to enable them to resist, the

page_text: pressure exerted upon them by the inking roller or it equivalent, while they yield
under the pressure of the harder printing cylinder or its equivalent and cause a printing
surface-as A,-to advance from its receded position and come in contact with the
paper or surface to be printed.
3. The use in such instruments or mechanisms as indicated in 1, of Cylinders,
prisms or plates as, A, sheets I, II, III-which revolve or swing about an axis-
as, CC, sheets I, II III and which present their surface or surfaces alternately to
the inking pad or part-as, N, and to the paper or surface to be printed.
4. The use in such instruments or mechanisms as indicated in 1, or in similar
instruments or mechanisms, of stereotypes or other printing devices-as C, sheets III
and IV-formed fastened or supported upon the surface and designed to print in the
ordinary way.
5. The use in such instruments or mechanisms as indicated in 1, or in instruments
or mechanisms similar thereto, of levers springs, inking pads or other parts which
extend or are placed under a part of the instrument or mechanism bearing a surface
for printing in the ordinary way-as C, sheets III and IV.
6. The use in such instruments or mechanisms as indicated in 1, of a broad spring
or plate as B, sheets III and IV extending and held in position under the form to
be printed in the ordinary way, while the end or ends-carries the device to be printed
with its own ink-as, A, sheets III and IV.
7. The use in such instruments or mechanisms as indicated in 1, of an endless
ribbon-as, C sheet IV, supplied with ink from a source within the instrument or
mechanism as N, W, L, sheets IV-and passing over the printing device, its
position being altered automatically in order that it may constantly present a
sufficiently inked portion to the paper or surface to be printed.
