I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention as
communicated to me by Albert König, of 42, Bahnhofstrasse, Guben, Brandenberg,
Germany, Printer, to be as follows:-
This invention relates to an automatic apparatus for feeding paper which
removes the uppermost sheet from a paper pile and feeds it to the particular
machine.
To a rotary shaft an iron disc is screwed, facing the flat side of which are
electro magnets, the
iron cores of which are likewise fixed to a
second iron disc. The second disc is moveable in the longitudinal
direction on the shaft, but in consequence of a spring, fixed to the shaft,
is forced to rotate with the latter. In addition, two steel pins placed diametrically
opposite to each other are attached to the second disc. These pins, together with
the second disc and the electro magnets are pressed by means of a spiral spring
along the shaft causing the pins to enter holes formed in a third disc said holes
corresponding in position with the said pins. A cruciform arm is firmly attached
to the third disc, which latter is loose on the shaft and is carried along in the
direction of rotation of the second disc by means of the steel pins attached
thereto.
If now the shaft be rotated the three discs will be rotated therewith, the third
however, only so long as the electro magnets are unsupplied with current. As
soon, however, as the electric circuit is completed through the magnets, by means
of contact rings and springs, they are attracted to the first disc, and thereby, the
pins secured to the second disc are disengaged from the holes in the third disc;
thus the third disc remains stationary. The construction of the apparatus, so
far as described is only intended to bring the cruciform arm on the third disc
to a standstill, as soon as current passes into the eletromagnets.
To each arm of the cruciform is pivotted an angle lever one arm of which
carries a small friction roller and the other arm carries a spring on the end of
which is a piece of polished rounded off horn. The four small friction rollers.

eccentric is prevented from rotating with the shaft, said fixed arm being likewise.

paper. When the cruciform arm is rotated, the pieces of horn rub against the
paper four times for every rotation. The eccentric must be of such a form that
the pressure applied to the paper, through the pieces of horn, is, as uniform.as
possible. By means of this frictional action, the uppermost sheet of paper is .

I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed as communicated to me by Albert
König, Printer, of Guben, Brandenburg, Germany, to be particularly described
and ascertained in and by the following. statement:-
This invention relates to an automatic apparatus for feeding paper which
removes the uppermost sheet from a paper pile and feeds it to the particular
machine.
Figs. 1 and 2 of the accompanying drawings are views in elevation and plan
respectively of the apparatus, Figs. 3 and 4 represent principal parts of the same.
To a rotary shaft an iron disc d is screwed, facing the Hat side of which are
electro magnets E, the iron cores of which are likewise fixed to a second iron
disc f. The second disc f is moveable in the longitudinal direction on the
shaft c, but in consequence of a feather g, fixed to the shaft c, is forced to rotate
with the latter. In addition, two steel pins and h² placed diametrically opposite
to each other are attached to the second disc f. These pins, together with the
second disc f and the electro magnets E are pressed by means of a spiral spring i
along the shaft causing the pins to enter holes formed in a third disc k, said
holes corresponding in position with the said pins. A cruciform arm L is firmly
attached to the third disc k, which latter is loose on the shaft c and is carried
along in the direction of rotation of the second disc f by means of the steel
pins and 2 attached thereto.
If now the shaft c be rotated the three discs d f and k will be rotated therewith,
the third however, only so long as the electro magnets E are not supplied with
current. As soon, however, as the electric circuit is completed through the
magnets. by means of contact rings s and springs r, (see Figs. 1 and 2) they are
attracted to the first disc d and thereby, the pins h¹ and he secured to the second
dise are disengaged from the holes in the third disc k; thus the third disc k
remains stationary. The construction of the apparatus, so far as described is
only intended to bring the cruciform arm L on the third disc k to a standstill, as
soon as current passes into the electro magnets.
To each arm of the cruciform is pivoted (Fig. 4) an angle lever m, one arm
of which carries a small friction roller n and the other arm carries a spring on
the end of which is a piece of polished rounded off horn H. The four small
friction rollers n run on an eccentric O, which is loose on the shaft c. By means
of a fixed arm P the eccentric O is prevented from rotating with the shaft c the

page_text: said fixed arm being likewise so arranged, that its flat side (Fig. 4) is turned
towards the pile of paper.
When the cruciform arm L is rotated, the pieces of horn H rub against the
paper four times for every rotation. The eccentric O must be of such a form
that the pressure applied to the paper, through the piece of horn H, is as uniform
as possible. By means of this frictional action, the uppermost sheet of paper is
gradually pushed forward, until its front edge comes into contact with a weak
spring which it presses against a stronger spring d' thereby closing an
electric circuit which excites the electro magnets E thus bringing the cruciform
arm L to a stand-still. By means of this apparatus, the uppermost sheet of a
paper pile is pushed forward, only within a certain limit, independently of the
extent to which the paper is under friction at the time.
In order to prevent the paper from being pushed obliquely two such apparatus,
which can be stopped independently of each other, are placed one on either side of
the paper pile.
The paper thus separated from the pile is fed to the machine by any suitable
mechanism.
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 is
Automatic apparatus for feeding sheets of paper to quick printing presses,
calendering machines, folding machines, and the like, the distinguishing feature
of which is a rotary rubber H so placed as to push forward the uppermost sheet
of the paper pile, and put out of action by means of electro magnets E at the
moment when the uppermost sheet of paper strikes against the spring d' causing
it to contact with the spring & thereby closing the electric circuit through the
electro magnets E, whereupon the sheet of paper, which has been separated from
the pile and pushed forward is fed to the machine by any suitable feeding
mechanism substantially as described and illustrated in the accompanying draw-
ings.
