Improvements in Means for Adjusting Sheets in Printing Machines.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., 18, Buckingham
Street, Strand, W.C., London, Patent Agent, do hereby declare the nature of this
invention, a communication to me from abroad, by Albert Joisten, Printer, of
31, Agrippasstrasse, Cologue, in the Empire of Germany, to be as follows:-
The devices hitherto used for sliding in the sheets or for keeping them straight
had the inconvenience, that they required excessive space.
This inconvenience is avoided by this invention.
The slides of which there are two, are moved by a double-armed or other lever,
which on its free end slides on a cam on the printing cylinder by means of a
roller or is lifted and lowered in any other manner.
The characteristic feature of this apparatus is, that the lever moves two arms
from one another, these arms are generally pressed against one another by means of
spring-pressure and are connected scissor-like with one another, so that the real
slides, which are connected to these arms, make the necessary sliding movement.
The lever carries on its front end a cone, which can be adjusted higher or
lower by means of a screw. In order to prevent a lateral movement of the lever,
it is guided at the front between two vertical bars.
When the one lever-arm moves, the cone presses apart the rollers on the arms,
which serve for obtaining easy working, and thus also moves the two arms which
are pivoted to one another.
The free end of one arm reaches between two stop-screws on the slide-block, on
which is fixed a slide by means of a screw. The slide moves in the dove-tail
guides of the table. When the cone is lowered, the slide will be moved laterally.
The free end of the other arm reaches into a hollow in another slide block on
When the
which the slide guided also on the table is fixed by means of a screw.
cone descends, this slide moves in the contrary direction to the former slide.
A downward movement of the cone thus results in the two slides moving
simultaneously towards one another.
On the joint of the arms is arranged a spring, which pulls the arms again
together when the cone returns, with each up and down movement of the cone the
two slides move alternately towards and from one another. This movement is
that required.
It is then only necessary to fix the apparatus at a certain point on the table,
and, when the one slide has been adjusted, to adapt the other one to this ad-
justment.
For the first purpose adjusting screws are provided, for fixing the dove-tail-
guide, care being taken that the one slide which is connected solidly with the
slide-block by means of the screw, has its right position.
Then the other slide is placed in corresponding position to the former slide by
adjusting exactly the screw on which the second slide is displaceable.

In this apparatus in spite of the use of two slides very little space is required
for the mechanism for moving the slides and especially little space in the longi-
tudinal direction of the printing cylinder, which is especially important in 5
practice.

Improvements in Means for Adjusting Sheets in Printing Machines.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of 18, Buckingham
Street, Strand, W.C., London, Patent Agent, do hereby declare the nature of this
invention a communication to me from abroad, by Albert Joisten, Printer, of
31, Agrippasstrasse, Cologne, in the Empire of Germany, and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
-
;
The devices used up to now for sliding in the sheets or for keeping them straight
require excessive space. This inconvenience is avoided by this invention and in
order to make the same more clear, reference is made to the accompanying draw-
ing, in which similar letters denote similar parts throughout the different views,
and in which:.
Fig. 1 is a plan of the novel construction, the two ends of the base-board A
and the right hand side of the slide being broken away.
Fig. 2 is a side view of said construction.
Fig. 3 is a front view of the slide b¹.
Fig. 4 is a side view of a slightly modified form of construction.
Fig. 5 is a view similar to Figs. 2 or 4 but showing again another form of
construction, and
Fig. 6 is a plan view of the roll 2 of Figure 5 together with the arm holding said:
roll.
In the form of construction shown in Figs. 1 and 2 the apparatus is provided
with two slides b, which are guided by aid of a dove-tailed groove o provided in
the base plate A. Between said two slides the base plate A has secured to it a
small plate a furnished with two guide ledges, c. The latter form also a dove-3
tailed groove. Two small slides c, c¹ arranged side by side within said groove are
connected with the slides b, b₁ by screws and nuts a, . Therefore, the slides b, b¹
are guided not only by the groove within the base beard A but also by the groove
formed by the guide ledges x, x'.
A bolt n secured near one end of the plate a forms the fulcrum for two levers
or arms c, el each of which is connected to one of the slides c, c¹ before mentioned.
The lever or arm e takes between the heads of two screws located upon the upper
side of the slide c, but the lever or arm el takes into a lateral recess of the slide c¹.
If, therefore, the levers e, el are moved away from each other the slides b, b¹ are
drawn towards each other, and reversely. To move the slides b, b away from
each other I make use of a fork like spring, m, Figs. 2, 4, and 5 held in place by
the bolt n, and havng its legs pressing against pins secured to the lower
surfaces of the levers c, e¹; and to draw the slides b, 61 towards each other I
make use of a cone p secured to one end of a double armed lever i supported

page_text: by lugs h projecting upwards from the plate a. The end of the lever i carrying
the cone takes between, and is guided by, lugs also projecting upwards from
the plate a.
The lugs are located between the levers e, c¹, and the cone p
takes between said levers when the other arm of the lever i is released. Owing
to the part p being a cone the levers e, c¹ are moved away one from the other.
To reduce friction and obtain an easy working the levers e, e¹ are furnished with
rollers ff located at the places of contact with the cone p, and to regulate the
extent of movement of the levers c, d with the sides b, the cone p may be
adjusted in height by a screw and nut g.
The whole apparatus is secured to the base plate or feeder-board A of the
printing machine in such a position that the outer or free end of the lever i
lies upon the impression cylinder and is preferably provided with a roll such as !
(Figs. 4-6) which then moves along upon a cam, or within a cam groove, formed
upon the printing cylinder, so that the lever is oscillated and the levers c, el
with the slides b, are moved to and fro as said cylinder rotates. The sheets are
put on either or both of the two slides bb so that they are adjusted sideways
by means of the projecting parts kk, respectively, when the slides bb' are moved
to and fro.
Instead of using a double armed lever such as i (Figs. 1 and 2) I may make
use of a one armed one such as 23 (Figs. 4 and 5) the lugs h¹ supporting this lever
being in this case located behind the screw or bolt n, and the guide lugs ¹ being
located at the place of the lugs h (Figs. 1 and 2): and instead of employing an
inverted cone as in Figs. and 4 I may use an upright cone proper 7, Fig. 5.
Also in this case the outer end of the lever 2 must be raised if the levers cel
shall be moved away one from the other, but in the form of construction represented
in Fig. 4 the lever is connected by means of a link with an auxiliary lever
carrying the roll 7. The latter, or the lever respectively, is operated in just the
same manner as in all the other forms of construction.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. In an apparatus for adjusting sheets in printing machines, the combination
with a slide such as b, and means for guiding the latter, of a lever adapted to be
oscillated in a vertical plane, and extending rectangularly to the direction of move-
ment of said slide another lever extending in about the same direction and being
adapted to be oscillated in a horizontal plane by said former lever, (and means for
transmitting the movements of the latter to the other lever and from this to
the slide, as set forth.
