COMPLETE SPECIFICATION.
Improvements in Chromatic Printing Blocks.
We FRED I. GETTY, a citizen of the United States of America, residing at
5121, North 5th Street, Springfield, Sangamon County and State of Illinois,
United States of America Gentleman and THE NATIONAL CHROMATIC PRINTING
COMPANY, a corporation organised under the laws of said State of Illinois and
having its principal office at Springfield aforesaid 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 :-
This invention relates to improvements in chromatic printing blocks, its object
being to provide a frame adapted to be set in the ordinary form of type and to
enclose and support two printing elements, one stationary and the other movable,
the stationary element being inked by the same mechanism as the body of the
form and the movable element being supplied with ink from a
pad or other
independent inking device. The invention is fully described and explained in this.
Specification and shown in the accompanying drawings, in which,
Figure 1 is a plan of a complete device embodying my improvements;
Figure 2 is a vertical section through the line 2-2, Figures 1, 4;
Figure 3 is a vertical section through the line 3-3, Figures 1, 4;
Figure 4 is a top plan of the entire device except the swinging frame and the
border fastened to it, certain parts being shown in section to illustrate construction ;
Figure 5 is a vertical section through the line 5-5, Figure 4;
Figure 6 is a vertical section through the line 6-6, Figure 4.
In Figure 6 the view is in the direction indicated by the arrow, al. Figure 4.
Figures 2, 3, 6, show the parts in their normal position, the vertically movable
frame being at its highest limit, and Figure 5 shows the frame depressed and the
printing bar raised to the position in which it prints.
In these views, A is a rectangular frame adapted to be locked in an ordinary
form of type and should be of less height than the type in the form. Within the
frame, A, is a closely fitting second frame, A', readily detachable from the
frame, A, and provided with a botton plate, a, formed with a rectangular and
approximately central opening to whose margin is fastened a third rectangular
frame, A', adapted to receive and support an electro-plate or type set in the usual
manner and having an upper face in the plane of the face of the remainder of the
form. The reason for forming the bottom plate, a, with an opening corresponding
to the space within the frame, A', is that electro-types as usually made are of the
standard height of the forms of type used on ordinary flat bed presses, and it is
therefore desirable to have the electro-types rest directly upon the bed of press
which supports the remainder of the form. One of the side walls of the frame, A',
is formed with two upwardly projecting ears, a', Figure 4, and to these ears is hung
one of the edges of a vertically oscillating rectangular frame, B, whose upper
surface is preferably provided with an ornamental border, B', screwed or otherwise
fastened to it. Between the frame, A2, and the wall of the frame, A', opposite the
ears, a', lies a block, C, provided with an inking surface of ordinary construction
and at the ends of this block and in the angles of the frame are screws, S, whose
heads lie in countersink in the frame, B, while their lower ends engage the bottom
plate, a, which is preferably reinforced by the small blocks, D, Figure 3. Each of
the screws is encircled by a coiled spring, s, which tends to press the edge of the

page_text: frame, B, upward and to hold it in the position illustrated in Figures 2 and 3. By
the application of sufficient force, however, the free edge of the frame, B, may be
pressed downward until the entire frame is horizontal, when the face of the
border, B', will lie in the plane of the face of the form. The two end bars of the
frame, B, are each provided with a downwardly extending plate, B³, Figures 2 and 4,
each of the plates being preferably formed with the flange, b, at its upper margin
and the flange being secured in a suitable recess in the lower face of the
corresponding bar.
Between each of the plates, B, and the corresponding end of the frame, A², is a
vertically oscillating lever, E, pivoted at one end between two vertical posts, e, e,
Figures 2, 3, 4, 5, the posts being fastened with the frame, A', and contiguous to
the ears, a'. In the free ends of the levers, E, E, are journaled two gudgeons, FI, F¹,
formed on the ends of a prismoidal printing bar, F, and extending through the levers,
and on each of the ends is formed or fastened a plate, F, corresponding in shape
to the cross-section of the bar and having pins, f, f, seated in and projecting
horizontally from its angles. Each of the levers, E, is provided with a spring
pawl, E, shown clearly in Figure 3, one of the ends of the pawl being in contact
with the margin of the plate, F2, and being adapted to prevent its accidental
rotation and to hold it in its exact working position either for inking or printing..
Between each of the plates and the corresponding lever, E, lies an oscillating
lever, L, pivoted near its center on a stationary horizontal pin, P2, whose ends are
supported in the corresponding walls of the frames, A', A', in the manner clearly
indicated in Figures 4 and 6. Each of the levers has in its opposite ends and
opposite faces two pins, P3, P4, which enter blocks, l, l, seated, respectively, in the
corresponding lever, E, and the corresponding plate, B2, and the relation of the
parts is such that the movement of the plates, B³, either downward or upward acts
through the levers, L, L, and moves the levers, E, E, in the opposite direction.
This being the case it is evident that when the free edge of the frame, B, is in its
raised position as shown in Figures 2, 3, the free ends of the levers, E, E, and the
printing bar, F, must be in their lowest position, the printing bar being in contact
with the inking pad as shown in Figure 3; and on the other hand when the free
edge of the frame is so.depressed that the frame is horizontal as shown in Figure 5,
the free ends of the levers, E, E, must be raised and the printing bar be thus
brought into position for printing.
On the inner face of each of the plates, B³, is pivoted a pawl, G, adapted to
engage any one of the pins, f, in the corresponding plate, F, and each of the pawls
is provided with an actuating spring, s', as shown in Figure 3. When the free
edge of the frame, B, is in its highest position as shown in Figures 2 and 3, the
pawl engages a pin at the upper angle of the corresponding plate, Fs, but as the
free edge of the frame moves downward and the free ends of the levers, E, E,
move upward, the pawl draws the pin downward and thus rotates the printing bar,
the parts being so proportioned that at each complete downward movement of the
free edge of the frame, B, the printing bar is rotated sufficiently to offer a fresh
face to the inking pad and expose a new face for printing.
The inking pad being provided with ink of any suitable color, the operation of
my device is as follows: As the form moves under the inking rollers, the upper
surface of the border, B', and the stationary type set in the frame, A³, are inked
in the usual manner, but the printing bar, F, being wholly below the level of the
type face, is not touched by the inking rollers. The inking-rollers being of
yielding material do not exert sufficient force upon the border, B, and the frame, B,
to overcome the resistance of the springs, s, s, and the position of the frame and
border is therefore not changed by the pressure of the inking rollers. As the block
passes under the paper-carrying cylinder, the border, B', and the stationary type
print an impression upon the paper, and at the same time the oscillating frame, B,
is pressed downward to a horizontal position and the printing bar, F, is raised, one
of its faces being brought into the plane of the face of the form so as to print upon
the paper an impression in the color supplied by the inking-pad. As soon as the

page_text: pressure of the cylinder is removed, the free edge of the frame, B, rises to its normal
position. and the printing bar descends upon the inking-pad. The result of the
entire operation is the printing in two colors of a single paragraph or advertisement,
the heading being in one color and the body of the advertisement in another. It is
not essential that the swinging frame, B, be provided with a border or other
printing face but I prefer to so construct it, since the border serves to connect the
two parts of the advertisement. We have spoken of the matter printed by the bar
as the "heading" of the advertisement, but it is not at all essential that it be
placed at the upper margin of the matter printed from the block as it may be
equally as well at either side if desired.
We do not desire or intend to limit my invention to the use of the particular
means for rotating the printing bar shown in the drawings, as it is evident that it
may be turned by other suitable means either step by step in one direction or in the
opposite directions.
The use of the outer frame, A, is not essential since the frame, A', and the parts
within it are readily detachable from the frame, A, and may be locked in the form
of type without it. I prefer to use the outer frame, as it is frequently a convenience
to remove the frame, A', and the working parts within it in order to change or
renew any element of the mechanism, and when the frame, A, is used this can be
done without disturbing the rest of the form. I do not desire or intend, however,
to make the outer frame A an element of the invention as it is merely a matter of
convenience and when in use may be regarded rather as a part of the form in which
the printing block is set, than as a part of the printing block itself.
Having now particularly described and ascertained the nature of this said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. The combination with a frame adapted to be set in a form of type, of a
vertically oscillating frame hinged at one edge to said first mentioned frame,
vertically oscillating levers connected with said vertically oscillating frame by
means insuring their opposite movement, a printing bar journaled in the free ends
of said oscillating levere, means for securing a stationary printing face within
said oscillating frame and said first mentioned frame and an inking surface lying
below the plane of said vertically oscillating frame being adapted to raise said
printing bar and bring it into the plane of the stationary printing face and the
upward movement of the oscillating frame being adapted to press the printing bar
against the inking surface.
2. The combination with a frame adapted to be set in a form of type and to
support a stationary printing surface, of two vertically oscillating levers supported
within said frame, a rotable printing har supported by said levers and raised and
lowered by their oscillation, an inking-surface lying below the plane of the face of
the form, a vertically movable element projecting normally above the plane of the face
of the form, and mechanism connecting said vertically movable element with said
oscillating levers whereby the motion of said movable element in either direction
imparts reverse movement to said vertically oscillating levers; substantially as
shown and described.
3. The combination with the frame, A¹, and the stationary frame, A2, within it,
of the oscillating frame, B, provided with the plates, B³, the levers, E, E, the
printing bar, F, the levers, L, L, connecting the plates, B, and levers, E, E, the
inking pad, C, and means substantially as shown and described, for partially
rotating the printing bar during its vertical movement.
4. The combination with the frame, A', and the frame, A', within it, of the
vertically oscillating frame, B, hinged to the frame, A', and provided with the
border, B, and plates, B, B2, the levers, E, E, printing bar, F, having gudgeons, F',
journaled in the levers, E, E, the levers, L, L, connecting the plates, B*,
levers, E, the plates, F, mounted on the ends of the printing bar and provided with
pins, ff, the pawls, E', E', mounted on the levers, E, and the pawls, G, G, mounted
and

page_text: on the plates, B', and adapted to engage the pins, f, and to partially rotate the
printing bar in its vertical movement; substantially as shown and described.
