Complete Specification Left, 20th June, 1890-Accepted, 16th Aug., 1890
Apparatus for Feeding Sheets of Paper to Printing and other
Machines.
We RANDAL ÜRESSWELL of 5 Bedford Place, Russell Square, Merchant and
BERNARD BLOOM of 24 Doughty Street, Engineer, both of London, do hereby declare
tlio nature of this invention to be as follows:-
This invention consists of a box having a bottom and 3 or 4 sides as preferred, the
back being left out if desired for convenience in refilling.
The bottom contains rollers, one or more of which are rotated by means of a pulley
and strap or in any other well known way.
These rollers are covered with india-rubber or cloth, or other suitable substance,
and they serve to impel the paper towards the delivery mouth, which is a slit of
snitable size in the front of the box: This mouth is closed or opened by the falling or
rising of a vertical bar which is lifted by an eccentric under its end, and falls by
gravity being attached to, or held by, slides on the box.
The spindles carrying these eccentrics may be rotated by a pulley and strap or
other mechanical means, or may be brought in and out of gear by magnetic action
arising from the revolution, of magnetized plates attached to a drum, or to the sides
of the cylinder of a printing machine. In this latter case a light spring could be
used to draw each spindle back to its rest or disengaged position. The two-end sides
of the box are constructed to slide to and fro by means of a dovetail with fixing
screw, which slides in a suitable channel on the surface of the bottom, and is aided
by studs acting as guides, so that the area of the box can be altered to suit different
sizes of paper.
The bottom of the box is by preference slightly sloping towards the mouthpiece.
The paper being cut to the size required is placed in the box, and as the cylinder of
the printing press revolves, it is passed through the mouth sheet by sheet, at the
necessary interval, the speed being controlled by the printing machine, which as it
revolves or returns, effects the action of the eccentric which lifts the door of the
mouth, the roller or rollers being set in motion at the saine instant, and a sheet of the
paper passed through to the receiver..

COMPLETE SPECIFICATION.
Apparatus for Feeding Sheets of Paper to Printing and other
Machines.
We, RANDAL CRESSWELL of 5 Bedford Place, Russell Square, Merchant, and
BERNARD BLOOM of 24 Doughty Street, Engineer, both of London, 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 is intended to furnish an adjustable automatic apparatus for the
delivery of paper or card to printing and other similar machines.
It consists of a box or tray having a bottom and three or four sides as preferred,
the back side being left out if desired for convenience in refilling.
The bottom contains rollers, one or more of which are rotated by means of a pulley
and strap, or in any other well known way.
These rollers are covered with india-rubber or cloth, or other suitable substance,

page_text: and they serve to impel the paper towards the delivery month which is a slit of
suitable size in the front of the box. This mouth, is closed or opened by the falling
or rising of a horizontal bar which is lifted by an eccentric under its end, and
falls by gravity being attached to, or held by, slides on the bar. The spindles
carrying these eccentrics may be rotated by a pulley and strap or other mechanical
means.
The bottom of the box is by preference slightly sloping towards the mouthpiece.
We will now describe the invention with reference to the accompanying drawings
in which Fig. 1 shews a side elevation, and Fig. 2 a plan of our apparatus. Fig. 3
shews an end elevation looking from the right. Fig. 4 shows an enlarged section
of the dovetail slide arrangement. a, shews the mouth; b, the horizontal bar;
ce, the eccentric cams for lifting the friction wheel on end of b; d, the
driving pulleye, e, the friction rollers; the pulleys for driving e, eg, the
adjustable side,, the bolts with dovetail ends;,, the slides in which the dove-
tail ends of h, h, work; m, the driving strap; k, the tray or box.
The sides, are adjustable inasmuch as they can be slid along the slides, in the
bottom of the tray, so as to approach each other more or less closely, according
to the width of the paper being fed. This is seen best in fig. 1 where segmental
shaped pieces are cut out of the sides g, to enable them to pass clear of the
rollers e.
The paper being cut to the size required is placed in the tray or box k. The
apparatus is then set in motion by the revolution of the cylinder of the printing
machine, whereupon the sheets of paper are passed through the mouth separately,
sheet after sheet at the necessary interval, the speed being controlled by the printing
machine which as it revolves or returns, actuates the eccentrics c, which lifts the
horizontal barb, forming the door of the mouth a; the rollers e, being
motion at the same instant and a sheet of paper pressed through to the receiver.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed; we declare that what we
claim is :-
In an apparatus for feeding sheets of paper to printing and other machines, the
combination of the mouth a, the horizontal bar and eccentrics b, c, and the tray k
with or without the rollers e é as herein explained and set forth.
