I, OTTO BERNHARD AUGUST KLUG, of Berlin, in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement:—
My invention relates to copying presses and consists essentially in the employment
of rollers in lieu of the pressing plates heretofore used; in the construction of the
press in easily detachable parts, for the purpose of enabling the same to be packed for
transport without difficulty and in the reduction of the weight to a minimum.
In the accompanying drawing
Figure 1 is a plan, and
Figure 2 a front view of a press constructed according to my invention.
Figure 3 is a side view, the pressure lever being in its inoperative position.
Figure 4 is a side view showing the said lever in the position for producing
the pressure.
Figures 5 and 6 are views illustrating modifications of the spring pressure device.
Figure 7 shows two views of a cranked handle hereinafter referred to.
The said copying press comprises two brackets a, a' which are adapted to be fixed
to a table or slab, at a suitable distance from each other by means of the screws b, b¹.
These brackets carry the lower pressing roller d in the bearings c, c', whilst the upper
roller e is supported in the bearings i, in the arms, which are capable of turning
upon the bolts in the hinges g, g².
:
The springs k, k¹ serve to produce pressure between the two rollers. These springs
are, on the one hand, fixed to the outer sides of the movable arms h, h¹ and on
the other hand are connected with the angle lovers 1, pivotted at m, m¹ by means of
screw bolts to the outsides of the brackets a, a'..

The turning of the levers 1, from the position shown in Figure 3 to that shown in
Figure 4 causes the tension of the springs k, kl.
The operation of the improved press when copying letters or the like, is
as follows.
After the press has been put together and fastened in a suitable position the
copying hook is placed between the rollers d, e. The pressure levers i, are then

page_text: moved towards the table to the position represented in Figure 4, and one of the rollers
(here the upper) is turned by means of the crank n. The copying book is thus moved
between the rollers under pressure and the copy is produced.
The
To enable the apparatus to be packed in the smallest possible space the roller d
is adapted to fit within the roller e. To permit this the journals of the larger roller e
are removable being attached to the guide pieces o which slide into the roller e.
said journals are prevented from turning when in place by lugs p arranged on
the guides and engaging with corresponding notches in the roller e.
In Figures 5 and 6 other arrangements of springs are shown, and the tension
levers, with their helical springsk, k¹ are dispensed with. The springs k, k¹ may
however be retained, the springs 2, 3 being then made use of to increase the pressure.
The present roller copying press produces excellent copies at a comparatively small
pressure or tension of the springs because, in contradistinction to the copying presses
having pressing plates by which the pressure is distributed over the whole surface so
that the whole page is copied simultaneously, the pressure here acts as it were only on
one line at a time, so that the copying of the writing is effected from line to line, that
is to say gradually.
The improved press by reason of the separability of its parts and its small weight is
specially adapted to be employed when travelling; it can however, also be used as a
stationary press.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim in
respect of my improvements in copying presses is
First. The employment of rollers which by means of springs arranged at suitable
points and capable of being stretched at the proper moment, can be pressed together
so that when turning the said rollers the copying gradually progresses, good
copies being thus produced with a comparatively small pressure.
Second. The arrangement of the rollers d, e the lower of which is securely supported
in the brackets a, a¹ and the upper in the pivotted arms h, ¹ in combination with the
springs, and pressure levers 1, 1, for the purpose of enabling the copying book to
be easily introduced between the rollers before the pressure is applied, and of
conveniently imparting pressure to the rollers by simultaneously turning the levers 11
in the direction of the table.
Third. The employment of two rollers of different diameters, the larger of which is
provided with removable journals which in use are kept in place by lugs arranged on
the guide pieces and engaging with corresponding notches in the roller, and when not
in use are drawn out so that one roller can be placed within the other, for the purpose
of economising space.
