Improvements relating to Apparatus for Feeding Sheets of Paper to
Printing Machines.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co, Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention and in what manner the same is to be performed to be
particularly described and ascertained and by the following statement:―
This invention relates to an improved arrangement or apparatus for automati-
cally picking up the sheets of paper for feeding to printing machines and by which
arrangement the top sheet, 19 lifted from one of the corners gradually along the
entire front edge until completely separated from the next lower sheet of the pile
The invention is illustrated in the accompanying drawing in which
Figure 1 is a vertical longitudinal section of the improved apparatus and
Figure 2 is a plan of a portion of the same
The lifting of the sheets 18 effected, as indicated in the drawing, by means of
elastic or spring-tongues a carried by a rod or har S and adapted to be moved
from the dotted position I into the position II shown in full lines, through the
intervention of partly cut-away dises e on the spindle B The cut away portion of
these discs enables the tongues to return to their initial position I owing to their
elasticity
The tongues a are provided with a beak in the form of a knife edge by means
of which they raise the front edge of a sheet each time they are moved from
position I into position II The arrangement 19 such that the first tongue al
further raises the corner which has been previously lifted up by any suitable means,
and 90 detaches a further portion along the edge of the sheet Hav-
ing thus placed the tongue a¹ into the position II, the tongue
a is next moved from position I into position II and thereby aises
another portion of the edge of the sheet and so on with all the tongues aa
in the proper order until the entire front edge of the sheet has been raised off the
pile. After this 18 accomplished the roller b 18 caused to move from its lower
position into its uppermost position and in this position it presses the raised
edge of the sheet against the bands X which run around the revolving cylinders W
and rollers fd and band which bands at once move the sheet to the bands y on
the cylinder R and rollers g', 'h and b The two sets of bands X and y guide the
sheet between them onto the feed table E near the printing cylinder
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim 18:-
An arrangement for automatically raising the front edge of a sheet, one corner of
which has been previously lifted, said arrangement being characterized by

over the whole breadth of the sheet underneath the entue front edge thereof so as
to detach the top sheet from the next lower sheet of the pile
