SIDE GUIDE ‘FOR PRKNTINGPRESSES

Application August 26, 1936, Serial No. 98,089
2 Claims. (Cl. 2'71-~59)
This invention relates generally to side guide
mechanism for printingpresses, and particularly
to ‘a sheet registering device for controlling the
being in vertical alinement with one another.
The power shaft 6 will be connected in any suit
able manner (not shown) with some movable
position of paper as it is fed into a lithograph or
5 printing press.
The invention consists generally in the ar
rangement of guide mechanism at the feed end
of the press for accurately registering‘ paper fed
to the press and capable of being quickly, easily
part of the: press so as to rotate when the press
is in motion, while the shaft 1 will be suitably
associated with some ‘part of the timing mecha
nism of the press feed so ‘as to oscillate at proper
and conveniently operated to change its position
intervals. The means by which this may be ac
complished, being well known and understood,
it is deemed unnecessary here to show or de
either while the press is in operation or at rest.
The invention consists. further in the arrange
ment of a carriage or carriages at the sides of
the press having mechanism thereon, operated
15 from the press for feeding the sheet to the stop
mechanism, and also means operated from the
paper feed mechanism for instantly releasing the‘
paper from the guide at the proper time.
The invention is carried out by means of the
20 mechanism hereinafter described and claimed
and a preferred embodiment of which is illus
trated in the drawing, wherein:
Figure 1 is a fragmentary front elevation
showing one of the side guides at the feed end
The registering means includes a carriage 9
supported by the said shafts and feed screw and
capable of traveling longitudinally thereon. This
carriage includes a table It so positioned as to
receive and support an edge or side of the sheet
gear l3 travels with the carriage and is keyed or 25
splined as at 14 to the power shaft 6. The power
roller 5 i has its upper periphery disposed substan
shown in Figure 1, and
Figure 3 is a sectional view taken substantially
upon line 3--3 of Figure 1.
The improved guide or registering device is
30
tially in the plane of the table l0 so as to con
The guide receives the sheets advanced to the
cylinder and automatically guides them into such
position as to be properly and accurately pre
sented to the gripper mechanism of the cylin
der. Should it be required that the adjustment
be changed, such change may be readily accom
plished either while the machine is in operation
or at rest, and from a position at the side of the
machine and convenient to the press operator.
In accomplishing these general results, there may
be provided a carriage including feed mechanism
45 for one or both sides of the sheet to be fed to
the press, and while but one of such feed devices
- is here disclosed, it will be understood that the
mechanism to be described may be duplicated if
desired at the opposite side of the press.
Arranged parallel with the cylinder at the feed
50
end of the press is a shaft or track member 5,
a power shaft 6, an oscillatory shaft 1 and a
feed screw 8. These members are all arranged
parallel with one another and relatively close to
55 gether, the power and oscillatory shafts 6 and l

to be fed to the press, the said table being usually
arranged in horizontal alinement with the upper
periphery of the'cylinder 4. The carriage 9 has
associated therewith a power roller H with its 20
axis disposed at right angles to the axis of power
shaft 6. The said roller receives its power
through beveled gears I2 and 13 connected to
the roller and the shaft 6 respectively. The

arranged in advance of the cylinder 4 of a con

associated with the usual feed board (not shown) .

scribe such power connections.
tact with the lower surface of a sheet l5 resting
upon the said table.
The carriage has a post or stop It extending
upwardly therefrom and to the upper end of
which an arm I’! is pivoted as at l8.
The arm,
thus pivoted intermediate its ends, is capable of
rocking upon the supporting post so that the 35
yoked end I9 is moved toward or- away from the
table it. This yoked end of the arm carries an
idler 2t adapted when in its lower position to
engage the upper surface of a sheet 15 and to
move the sheet into frictional contact with the 40
underlying power roller ll. When so engaged,
the direction of rotation of the said roller being
as indicated by the arr-ow in Figure 1, the sheet
i5 will be caused to move laterally until it con
tacts the stop or post I6. The yoked end of arm 45
it may be equipped with a plate 2| to prevent
buckling of the sheet.
The opposite end of arm I1 is pivotally con
nected as at 22 to the upper end of a pin or rod
23, the latter being threaded as shown to carry 50
adjusting nuts 24 and 25. A ?nger 26 keyed or
splined as at M to the shaft 1 has its outer end
engaged with nut 25 of the pin or shank 23, and
an expansion spring 28 encircling the said shank
is engaged between the finger and the upper 55
2

clamp nut 24. It is obvious, therefore, that the
tension of the spring 28 may be accurately ad
justed by manipulation of the nut 24.
The feed screw 8 has suitable bearing at its
ends in the frame 29 of the printing machine,
and is equipped with a hand crank 30 by means
of which it may be manually rotated. Opera
tion of the hand crank causes the feed screw to
be rotated, moving the carriage and its asso
10 ciated mechanism in a direction determined by
the direction of rotation of the screw.
Such an
adjustment permits of accurate setting of the
carriage so that a proper registry may be at
tained.

In operation, the timing shaft 1 oscillates so
as to move the ?nger 26 downwardly, causing
arm l1 to rock upon its pivot and move the idler
20 out of the path of travel of a sheet fed to
the table II], as shown by dotted lines in Figure 1.
20 As soon as the sheet engages the table, the shaft
1 assumes normal position, whereupon the idler
drops and moves into sheet engaging or clamp
ing position above the power roller I I. As the
latter is constantly rotating, the sheet is gripped
25 and is moved laterally upon the table It! until
the side of the sheet engages the stop or post IE,
it being understood that the position of such stop
or post properly de?nes the lateral margin of
the sheet. The timing mechanism is also oper
30 ated to move the idler 20 out of contact with
the sheet as soon as the cylinder 4 arrives at the
proper position for taking the sheet, so that the
latter is free to move from the registering device
immediately this occurs. The adjusting nut 24
35 enables the tension to be adjusted to compensate
for different weights of paper stock fed to the
press.
From the foregoing it is apparent that I have
provided an extremely simple side guide and yet
one which is capable of most accurate adjust
ment and easy and convenient of access by an
operator. The construction and arrangement of
the guide is such that adjustments maybe made
at any time Without stopping or slowing down
the press.
Having thus described my invention, what I
claim is:
1. In a sheet registering device, a power roller
adapted to be engaged by a sheet, an arm piv
oted adjacent to said roller, an idler carried by 1O
said arm and adapted to move in paper clamping
engagement with said roller, a pin connected to
said arm, a ?nger having an opening in one end
to- loosely receive said pin, an adjusting member
on said pin, a spring interposed between said ?n 15
ger and said member, a nut on said pin engaging
the ?nger on the side opposite to said spring,
and a timing device controlling the movements
of said ?nger.
2. In a sheet registering device for printing 20
machines, a carriage associated with said ma
chine and movable laterally of the path of travel
of a sheet in said machine, a stop on said car
riage, a power roller on said carriage adapted to
be engaged by the sheet in its travel, an arm 25
pivoted upon said carriage, an idler carried by
said arm and adapted to move in paper clamping
engagement with said power roller, a pin con
nected to said arm, a ?nger, said ?nger having b:
O
an opening therein to receive said pin, an adjust
ing member on said pin, an expansion spring
encircling said pin and interposed between said
?nger and said adjusting member, a nut on said
pin engaging said ?nger on the side of the lat
ter opposite to said spring, and a timing device
controlling the movements of said ?nger.
