LATERAL REGISTRATION APPARATUS

2 Claims, (Cl. 271-59)
The present invention relates to apparatus for
the lateral registration of sheets in printing
presses and other machines of the kind in which
a member movablelaterally in relation to the
5
10
direction of movement of the sheets is pressed
against the sheet and either pushes or pulls said
sheets against lateral stops.
The object of the invention is to provide a sim
pli?ed and reliable apparatus of this kind.
An embodiment of the invention is shown in
the drawings wherein Figures 1-3 show a side
view of the apparatus in different working posi
tions and Figure 4 is a plan View from above of
the apparatus.
15
At the one side of the table (not shown in the
drawings) on which the sheets are forwarded to
the printing press a frame I is provided, in which
is mounted a shaft 2, to which, by means of a
suitable driving mechanism not shown in the
20 drawings, is imparted an oscillating or rocking
movement. _On one end of the shaft 2 is ?xed a
bevel gear wheel 3 which meshes with another
bevel gear wheel 4 ?xed to a shaft 5 which is
rotatably mounted in the frame I. This shaft
25 5 carries a crank 6, to the free end of which, one
end of an arm ‘I is pivotally connected, the other
end of said arm being ?xed to one end of a link
or rod 8.‘ On a guide rod 9, connected to the
frame I and disposed at right angles to the di
30 rection of movement of the sheets, is slidably
mounted a slide ID on which an arm I2 is swing
ably mounted by means of a pin II, the free end
of said arm I2 being connected to the link 8 by
means of a crank pin I3. The swinging move
ment of the arm I2 is limited on the one side by
a ?xed abutment I4 rigidly connected to the slide,
and on the other side by an adjustable screw I5
carried by the slide and serving as an adjustable
abutment. To the boss I6 of the arm I2 is con
nected one end of a springy arm H, the free end
I8 of which forms such an angle with the other
portion of the arm I‘! that when the arm I‘! occu
pies the position shown in Figure 2 the end por
tion I8 rests entirely against the sheet I9, which
45 is on the table provided before the cylinder of
the printing press. Slide ID has mounted there
on and extending downwardly therefrom a sup
porting member 23 which in turn carries a sup
porting arm 25 extending therefrom. Said sup
porting arm 25 is so positioned from said slide ID
as to support sheets I9 at the point directly be
low the contacting point of the end I8 of arm I‘!
upon the sheet and thereby cooperates with
end I8 in holding and moving sheets I9. A brake
55 shoe 20 (see Figure 4) carried by the slide I0 is
pressed by means of a Spring 2| against a rod 22
which projects from the frame I and is disposed
parallel to the guide rod 9.
The apparatus operates in the following man
ner.
When the parts occupy the position shown in
Figure 1 and the driving shaft 2 is turned, the
arm 6 will by means of the bevel gear wheels be
swung in the direction indicated by the arrow
in Figure 1. On account of the action of the 10
brake shoe 20 the arm I2 carried by the slide ID
will ?rst begin to be swung to the position shown
in Figure 2, in which the adjustable screw I5 pre
vents its further movement. The screw is so ad
justed that the end portion I8 of the springy arm
I1 will be pressed on the sheet I9 with such a
pressure, that said arm I1 will be slightly bent.
When the driving shaft 2 is further turned in the
same direction the crank 6 will be moved to the
position shown in Figure 3. By means of the
arm ‘I and the rod 8 the slide II] with the springy
arm I1 is now moved perpendicularly to the di
rection of movement of the sheets. By means
of the screw I5 the pressure with which the end
portion I8 of the springy arm I'I rests against 25
the sheet I9 may be adjusted that when the slide
Ill moves the sheet I9 will be pushed by the end
portion I8 of the springy arm I‘! until the edge
of the sheet meets the ?xed abutment 23. Dur
ing its further movement the end portion I8
slides over or along the sheet to the end portion
shown in Figure 3 without wrinkling the same.
When the driving shaft thereafter is rocked in
the opposite direction and the rod 8 consequently
moves in the direction indicated by the arrow in
Figure 3 the arm will be swung upwardly to the
position shown in Figure 1. After the projec
tion 24 of the arm I2 has contacted with the
abutment I4 the slide II] with the lifted springy
arm I'I will be brought back to the initial posi 40
tion shown in Figure 1.
By means of the screw I5 the pressure actuated
by the arm I‘! against the sheet can be adjusted
at will, and this pressure will remain unchanged
even if the braking action of the brake shoe 22
changes.
Having now particularly described and ascer
tained the nature of my invention, and in what
manner the same is to be performed, I declare
that what I claim is:—
