A mounting particularly adapted for a shaft of printing press cylinder to position the cylinder in parallelism with a companion cylinder comprising a pair of identical brackets adapted to be mounted on laterally spaced upright supports for holding opposite ends of the shaft wherein one bracket is positionable to be horizontally adjustable and the other vertically and wherein each bracket consists of two parts mating along a parting plane extending in the central axis of a bore defined by opposing semi-cylindrical concavities formed in respective parts when they are connected to each other, the parting plane being so located that each has one end terminating at one side of the axis of the bore and the other end at the other side of the axis so that one part of each bracket may be mounted on its related support and will cradle the respective end of the shaft so that it will not fall out of its concavity and thus the other part of each bracket may be easily assembly with the one part without the necessity of physically holding the cylinder in place.

BACKGROUND OF THE INVENTION 
In the art of mounting printing cylinders, which are large and heavy and of 
substantial length, the installation is tedious and requires two workers. 
Basically, in common practice bearing journals are inserted over the ends 
of the cylinder shaft and the the bearings are bolted to the side supports 
while the cylinder is held in place. The bolts are aligned with the 
threaded openings in the supports and tightened. Manipulation of the 
unwieldy cylinder is nonproductively time consuming and frustrating. 
Other devices require parts to be different on one support than the other 
which must be threaded and unthreaded on the support for moving the 
cylinder supporting brackets. These are difficult to maintain and require 
special supports and thereofore have only specific application, and thus 
are not adaptable to universal use. 
SUMMARY OF THE INVENTION 
This invention relates to brackets primarily adapted for mounting printing 
cylinders. 
A broad object of the invention is to provide mounting brackets which are 
relatively simple to manufacture and which provide adjustment vertically 
as well as horizontally depending on their disposition on associated 
supports. 
A different object is to provide a bracket which is easily adjustable 
comprising an elongated straight slot formed in the body of the bracket, 
the bracket being secured to an associated support by bolts extending 
trough the slot and the bracket being movable lengthwise of the slot on 
the securing bolts which are abutted by adjusting screws threaded in the 
body and extending into opposite ends of the slot. 
A further object of the invention is to provide a novel bracket mounting 
for a cylinder and the like in which the bracket is split in a novel 
manner to maximize support for the roller and at the same time to provide 
adequate stock to permit bolting of the parts together and to an 
associated support. 
A further object is to provide brackets which may be easily mounted from a 
pair of upright supports by which a printing cylinder is adapted to be 
carried, each bracket comprising a pair of complementary sections defining 
a cylindrical shaft-receiving bore therebetween, one of the sections 
having an elongated slot extending transversely of the bore for reception 
of securing bolts therethrough which are threaded into the supports, there 
being a pair of adjusting screws at opposite ends of the slot for 
abuttment with the bolts, and the screws by threading and unthreading 
reacting against the bolts and moving the bracket lengthwise of the slot. 
Another object of the invention is to provide identical brackets for 
mounting opposite ends of a shaft of a printing roller or cylinder, the 
brackets being orientable so that one can be vertically adjustable and the 
other horizontally so as to position the cylinder in parallelism with an 
opposing cylinder. 
A primary object is to provide such identical brackets each of which 
comprises two parts which mate along a parting plane of approximately 80 
degrees to the vertical whereby the bottom portion of the bearing surface 
of the sector of the shaft-receiving bore extends slightly beyond the 
central axis of the shaft mounted thereon while the other bracket which is 
offset 90 degrees with respect to the vertically adjustable bracket is 
located to position its parting plane at 10 degrees to the horizontal and 
the bearing surface thereof is underposed 80 degrees about the shaft in an 
area under the axis of the shaft and 10 degrees above the axis. Thus one 
workman alone is able to mount a cylinder on the brackets and then fasten 
it on by placing one end of the cylinder shaft in the bearing surface of 
the horizontally adjustable bracket part and then fitting the other end of 
the shaft into the bearing surface of the vertically adjustable portion 
over the 10 degree upwardly curving portion extending beyond the vertical 
plane of the axis of the shaft.

DESCRIPTION OF THE INVENTION 
This invention is illustrated in conjunction, with a pair of press 
cylinders 2 and 4, the lower cylinder 2 having a center shaft 6 supported 
at opposite ends on a pair of bearings 8,8 suitably connected or mounted 
on a pair of side supports or frame members 10,10 of a printing press. 
The lower cylinder as shown in the drawings is not adjustable and its 
horizontally disposed center shaft 6 is shown as having its ends 
protruding through openings 12, 12 in the supports 10,10 for connection to 
associated driving components. 
The upper cylinder 2 has a center shaft 14, which may be provided with 
bearings (not shown) for rotatably mounting the cylinder 2. 
For purposes of this invention it is of no moment if either cylinder 
rotates freely or is driven or if one is stationary. 
The upper cylinder has its center shaft supported at its ends by identical 
adjustable brackets 15,15. Each bracket 15 is preferably square in side 
elevation and has sides 16,18, 20 and 22 and has a center aperture or bore 
24 in which an end portion of the shaft 14 is reposed. The bracket is 
formed of a pair of asymetrical mating sections or portions 26,28 divided 
by a transverse parting cut or line lying in a diametrical plane passing 
through the bore 24. The body portion 30 of the section 26 is wider than 
the body portion 32 of the section 28 although both are of the same 
thickness and the former has an elongated slot 34 formed therein extending 
through the lateral sides 36,38 and extending lengthwise substantially 
parallel with the edge 22. 
At the ends of the slot 34 there are provided a pair of adjusting screws 
40,42 which are threaded as at 44,46 through the end portions 48,50 which 
interconnect the body portion 26 with the retainer strip 52. 
A pair of bolts 54,56 are inserted through the slot 34 spaced from the ends 
thereof and are threaded as at 58,60 into the respective side supports 10. 
The inner ends of the screws, which extend transversely of bolts 54,56, 
are in contact with the respective thereof and are adapted to be threaded 
and unthreaded to raise and lower the respective bracket as seen in FIG. 2 
or to move it horizontally as seen in FIG. 1. Thus each bracket is 
identical with the other but depending upon its orientation it either 
adjusts vertically or horizonzontally. 
The bolts 54,56 have heads 62,63, which engage the side 36 and thrust the 
side 38 against the respective support. It will be noted that the bolts 
mounting the bracket in FIG. 1 are horizontally aligned and the bolts 
mounting the bracket in FIG. 2 are vertically spaced and aligned. 
The two portions of each bracket are secured to each other about the shaft 
by bolts 64,65 which extend through opening 66,67 in the body 32 of part 
28 and are threaded into threaded apertures 68,69 in the body 30 of part 
26. 
Thus it will be apparent that after the body part 30 of one bracket, such 
as shown in FIG. 1 which is oriented for horizontal adjustment, is secured 
to its support 10, the installer then secures the other bracket part 30 as 
shown in FIG. 2 for vertical adjustability. The installer then lays one 
end of the shaft 14 on the body part 30 of the bracket shown in the 
orientation of FIG. 1 within the upwardly facing semicylindrical sector or 
concavity 70 of the bore 24 which appears U-shaped in side elevation and 
then places the other end of the shaft within the laterally facing bore 
sector or concavity 70 of the part 26 of the other bracket shown in FIG. 2 
behind the lower cusp 75 of the sector or concavity 70 which extends 
beyond the central axis X of the shaft 14. In the position of FIG. 2 and 
in FIG. 3, the concavity sector 70 appears C-shaped in side elevation. 
In view of the orientation of the plane of separation between the parts, 
the bracket in the position of FIG. 1 provides a nondislodging seat to one 
end of the shaft and the bracket as oriented in FIG. 3 cups the shaft 
sufficiently to hold it in place albeit temporarily. However the installer 
immediately attaches the cap portion 28 to base part 26 of the bracket in 
FIGS. 2 and 3 and then proceeds to attach the cap part 28 to the base part 
26 of the bracket of FIG. 1. 
To adjust the left bracket (FIG. 1) the bolts 54,56, which are not 
initially drawn tight permit the related bracket to slide sidewise within 
the associated slot 34 as the adjusting screws 40,42 are threaded or 
unthreaded to align the top cylinder 2 in a horizontal plane with respect 
to the bottom cylinder 4. 
Then the vertical adjustment of the right bracket (FIG. 2) proceeds to 
raise and lower the respective end of the cylinder 2 until it achieves 
parallelism. This, of course is achieved by threading and unthreading the 
screws 40,42 against the bolts 54,56 which have not previously been drawn 
tight. Bolts 54,56 of both brackets are tightened after the adjustment is 
completed. Also the bolts 63,64 are tightened, which had been left 
initially loose. 
Having described the invention in its best mode, it will be apparent that 
to those skilled in the art many variations will now be suggested which 
are intended to be covered by the appended claims.
