Improvements in and connected with Copying-machines for Letters
and the like.
I, ALBERT ELTzbacher, of Bonn, in the Province of the Rhine, Kingdom of
Prussia, German Empire, Merchant do hereby declare the nature of this invention
to be as follows:-
This invention relates to a machine intended to be used for quickly and well
copying letters and the like by means of a broad endless band passed through a
wetting-vat, and over a copying-roller, the latter working in conjunction with a
squeezing-roller adapted to free said band of any excess of water, and with another
copying roller adapted to press the letter to be copied and the copying-paper
proper one upon the other, so as thereby to effect the copying. The purpose of
my invention is to produce copies upon so-called silk-paper, and to prevent the
latter from being wetted too much, as well as from being exposed to an undue
tension, both points causing the silk-paper to be very easily torn, and the copies
reudered, thus, useless.
In order to make my invention more clear, I refer to the accompanying drawing,
in which similar letters refer to similar parts throughout the different views, a
and
in which:
Fig. 1 is a perspective view of the apparatus, some parts being broken away,
and
Fig. 2 is a vertical longitudinal section through the same.
A is the endless moistening band, which is held by the upper, large roller B,
and the lower, small roller F, the latter being arranged within the vat H.
A roller C arranged in one horizontal plane with roller B is employed for freeing
the band A of any excess of water, so that said band retains only as little water as
just sufficient for moistening the silk-paper, or copying-paper respectively, in the
necessary degree.
The copying proper is effected between the rollers B and D, the latter of which
may be pressed upon roller B by means of the eccentric L, so as thereby to
increase or decrease, or regulate respectively, the pressure which the paper is to be
exposed to. The paper is brought between the rollers B and D by means of the
table K, which terminates shortly before the line of contact of said two rollers.
The letter etc. to be copied is first placed upon a suitable piece of silk paper, and
is then passed through between the two rollers D and B by turning the latter by
means of the crank E. The silk paper is during that time moistened by the
band A, and is thus made able to receive the copy.
In order to prevent the roller D from collecting up moisture upon its surface,
I prefer to arrange a drying-roller I having some layers of blotting-paper wound
upon it; said roller I is held, and pressed upon roller D, by means of spring a, as
distinctly shown in Fig. 2.
Roller C may, if desired, be made adjustable with regard to roller B, so as
thereby to regulate the pressure between said rollers C and B, or the degree of
moisture of band A respectively.
Dated this 23rd day of March 1895.

I, ALBERT ELTZBACHER, of Bonn, in the Province of the Rhine, Kingdom of
Prussia, German Empire; Merchant 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 :-
This invention relates to a machine intended to be used for quickly and well
copying letters and the like by means of a broad endless band passed through a
wetting-vat, and over a copying-roller, the latter working. in conjunction with a
squeezing-roller adapted to free said band of any excess of water, and 'with another
copying-roller adapted to press the letter to be copied and the copying-paper
proper one upon the other, so as thereby to effect the copying. The purpose of
my invention is to produce copies upon so-called silk-paper, and to prevent the
latter from being wetted too much, as well as from being exposed to an undue
tension, both points causing the silk-paper to be very easily torn, and the copies
rendered, thus, useless.
In order to make my invention more clear, I' refer to the drawing sent in with
Provisional Application, in which similar letters refer to similar parts throughout
the different views, and in which :-
Figure 1 is a perspective view of the apparatus, some parts being broken away,
and'
Figure 2 is a vertical longitudinal section through the same.
A is the endless moistening band, which is held by the upper, large roller B,
and the lower, small roller F, the latter being arranged within the vat' H.
A roller C arranged in one horizontal plane with roller B is employed for freeing.
the band A of any excess of water, so that said band retains only as little water as
just sufficient for moistening the silk-paper, or copying-paper respectively, in the
necessary degree.
The copying proper is effected between the rollers B and D, the latter of which
inay he pressed upon roller B by means of the eccentric L, so as thereby to
increase or decrease, or regulate respectively, the pressure which the paper is to be
exposed to.
The paper
is brought between the rollers B and D by means of the
table K, which terminates shortly before the line of contact of said two rollers.
The letter etc. to be copied is first placel upon a suitable piece of silk paper, and
is then passed through between the two rollers D and B by turning the latter by
means of the crank E. The silk paper is during that time moistened by the
band A, and is thus made able to receive the copy.
In order to prevent the roller D from collecting up moisture upon its surface,
I prefer to arrange a drying-roller I having some layers of blotting-paper wound
upon it; said roller I is held, and pressed upon roller D, by means of springs a, as
distinctly shown in Fig. 2.
Roller C may, if desired, be made adjustable with regard to roller B, so as
thereby to regulate the pressure between said rollers C and B, or the degree of
moisture of baud A respectively.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I'declare that what I
claim is :-
1. In a copying-machine having two copying rollers, the combination with one
of the latter, and with a vat containing water, of an endless band held by said
roller, and dipping into said water; a squeezing-roller adapted to press said band

page_text: against the said roller, and to free the said band from any excess of water;
a drying-roller arranged in contact with the other copying-roller, and adapted to
take up the moisture collected upon the latter, for the purpose as described.
2. In a copying-machine having two copying-rollers, an endless band held by
one of said rollers, and a vat for moistening said one roller by the mediation of
said endless band, the combination with the other of said two copying rollers, of a
drying-roller covered with blotting-paper, and arranged so as to be in contact
with said other roller; springs adapted to press said drying-roller against the said
other copying-roller, for the purpose as described.
Dated this 24th day of October 1895.
