Application December 20, 1935, Serial No. 55,465
19 Claims. (Cl. 101-479)
> This invention is an improvement in printing
presses of the type originally disclosed in Bech
man’s Patent No. 867,230 dated October 1, 1907,
and more particularly as disclosed in my com
.5 panion
application
for
Newpaper
printing
presses, ?led June 4, 1934, Serial No. ‘729,013.
The invention disclosed in said application
provides a multi-unit press and folder, said'press
having a plurality of interchangeable printing
30
'
printing mechanism with a single or double color
can be arranged in any desired relation in a
line. Any desired number of units may be em~
ployed to produce a straight line, straight run,
bers 3 and in blocks 30 which are fastened to
paper or papers of any desired size or number of
15 pages.

Each printing unit comprises a perfecting
attachment, and as shown the perfecting unit
consists of cylinders I and la, and co-acting im
pression cylinders 2 and 2a. The impression 10
cylinders Z-and 2a are journaled at opposite ends
in bearingspartly formed in the side frame mem
10 units and a folder unit or units; which units

Such invention provides a simple. and attrac
tive press for newspaper publishers who desire
increased production and‘ prefer‘the single page
plate economies and efficiencies and which press
will conserve and retain all the advantages of
the single so-called “tubular” presses in ‘produc
tion and operation, with greatly increased net
production speed; and in which any unit ‘may be
put into or out of operation as desired.
The objectiof the present invention is to pro
vide means whereby two plate cylinders are ar
ranged in printing relation to- a single blanket
cylinder in such manner that if desired the paper
may be printed in multi-colors in a single pas~
sage through the press; and also to provide
means whereby the extra plate cylinders may be
put out of operation if it is desired to only print
in one color.
‘
Further objects of the invention are to provide
novel means whereby the plate cylinders may be
independently adjusted relatively to the related
impression cylinder, both for producing the im
pression pressure and also to enable the plate cyl
inder to be placed out of operative position if it is
40 not desired to use same.
The accompanying drawings illustrate a prac
tical embodiment of my invention, and I will de
scribe the same in detail with reference to said
‘drawings, and summarize in the claims the es
45 sentials of the invention and novel combinations
and construction of parts for which protection is
the members 3 by means of bolts 3d. The plate
cylinders I and la are respectively journaled in 15
annular heads do, on the lower ends of hangers
4, shown; more in detail in Figs. 3 and 4. The
hangers 4 are adjustably secured to the outer
sides of the journal blocks 30 by means of bolts
40 which pass through slots 41)- in the hanger
and are tapped into the blocks 3c. The hangers'
4 are vertically adjustable so as to regulate the
impression pressure contact between the plate
cylinder and its related impression cylinder, by
means of a supporting screw 4d which is rotat
ably suspended in a lug 3e on the adjacent block
3c, said screw having a threaded engagement
with a socket in the upper end of the hanger 4
(see Figs. 3 and 4) . The hanger 4 can be raised
or lowered so as to adjust the plate cylinder l or
Ia as desired relative to its related impression
cylinder by ?rst loosening the bolts 40 and then
turning hanger bolt 4d. After the cylinder is ad
justed it is fastened in adjusted position by tight
ening bolts 40‘.
35
In the construction shown in Figs. 1 and 2 a
multi-color cylinder Mn is located above each im
pression cylinder and is adapted to cooperate
therewith when it is desired to print in multi
color. The cylinder lm (see Figs. 3 and 4) is
mounted in heads on the lower ends of hangers
5 which are hung at their upper ends on pins 5a
engaging eye-lugs 6a on vertically adjustable
blocks 6. Each block 6 is hung on a rotatable
bolt 6b tappedinto the upper end of block 6 and
hung on an eye 1a‘ attached to an upper frame
desired.
In said drawings:
member "I mounted upon and secured to the top
Fig. 1 is a side elevation of a printing press
constructed in accordance with my invention.
The members 5 and 6 when properly adjusted
vertically may be rigidly clamped in position by a 50
through-bolt 50 which passes through slots in
the members 5 and B and is tapped into- the frame
member ‘I. When it is desired to adjust the
cylinder im. the bolt 50 is loosened, then screw
Bbxis adjusted to raise or lower cylinder lm to the 55
of member 3.

away from the related impression cylinder; and
the hanger and cylinder may be held in such
10 non-operative position by adjusting a bolt 56,
tapped in the side of casting 5, until its inner end
engages a groove 5)‘ in the bolt 50.
When bolts 50 are loosened their screw threads
force them axially outward allowing the hangers
5 to swing outwardly on the pins 5a. The posi
tion of the plate cylinder relative to pins 50a is
such that it tends to swing outward by gravity
when bolts 50 are loosened.
Should the force of
gravity be insufficient to give the required clear
ance between the two cylinders the inner ends of
the screws 5e contact with the sides of the
grooves 51‘ in the bolts 50 and force the hangers
5 to swing outwardly on the pins 5a, and also pre
vent the cylinder from swinging back to its
former position until the bolts 50 are again tight
ened. Tightening the bolts 50 forces the hangers
5 against the blocks 6 which are then held against
the frames 1.

For a 32 page machine two
more units would be employed.
Any number of such units may be employed,
I claim:
1. A printing press having side frames, coact
ing plate and impression cylinders, fixed bear~ 10
ings for the impression cylinder on said frames,
bearings for the plate cylinder slidably mount
ed on the outer edges of the side frames and
adjustable in a straight line toward or from the
impression cylinder.
2. In a printing press as set forth in claim 1,
15
adjustable hangers carrying the bearings for the
plate cylinder, means for adjusting the hangers,
and separate means for securing the hangers in
adjusted position.
20
3. In a printing press as set forth in claim 1,
hangers supporting the bearings of the plate cyl
inder, adjustable blocks to which the hangers
are swingably connected, means for adjusting
the blocks, and means for fastening the hanger 25
and blocks to secure the cylinder in adjusted
position.
4. In mechanism as set forth in claim 1, swing
The cylinder lm is also adjustable vertically
relatively to the impression cylinder 2a by means
able hangers supporting the plate cylinder bear
ings, means whereby the hangers may be fas
of the screws 6b (Fig. 3) which are a duplicate
tened to hold the cylinder in contact with the
impression cylinder, and means whereby the
hangers may be held outwardly to keep the plate
cylinder out of contact with the impression cyl
inder.
35
5. A printing press having side frames, im
of the screws 40/. by which the lower cylinder
hangers 4d are adjusted.
Each plate cylinder i, l a is adapted to carry
cylindric plates P, (Figs. 1 and 2) each of which
will print one newspaper page of matter. The
plates receive ink from suitable inking devices
mounted below the cylinder in the side mem
bers of the unit frame.
Each plate cylinder lm may also be supplied
with ink from an inking mechanism mounted
in the frame members 1 above such plate cyl
inder. As the inking mechanisms form no part
of the present invention it is unnecessary to de
scribe the same herein, and they are simply dia
grammatically illustrated in the drawings.
Ordinarily the ink for the lower plate cylin
ders I and la will be black; and the ink for the
upper cylinders lm would be colored. In the
construction shown in Figs. 1 and 2 a sheet
could be perfected in black and also in color.
In the construction shown in Figs. 5 and 6 only
one multi-color cylinder lm is shown, and one
set of inking mechanism mounted as above de
scribed upon a frame member "Jr on top the
frame 3.
The frames l’ and law are preferably
made interchangeable, so that a frame 1x could
be removed and replaced by a frame ‘I carrying
two cylinders lm and their inking mechanism,
and thus enable the paper to be printed in
more colors.
The web can be led through the press in vari
ous ways. As indicated in Figs. 1 and 2, the web
can be led up over a guide roller 8 and thence
between the cylinders l and 2, and.
thence down between the cylinders 2,
between the cylinders la and 2a and
ders 2a and Im, to a guide 8a, and
Im and 2,
2a; thence
the cylin
thence up
over a guide 8b to a folder (not shown). By
‘ varying the lead of the web, or using different
colored inks in the lower fountains, a large variety
of multi-color effects can be produced.
If each printing unit of the press is two plates
wide, it will print four pages in multi-color. Six
such units would produce 24 pages, the equiv
pression cylinders mounted on the frames, ver
tically adjustable hangers carrying bearings for
the plate cylinders slidably mounted on the outer
edges of the side frames, plate cylinders jour
