I, FREDERICK WILLIAM VICKERY, of 14, Newcastle Street, Farringdon Street,
City of London, Ruling Machine Maker, do hereby declare the nature of this
invention to be as follows:-
This invention relates to a transverse reciprocating board or boards or strips
on which a gauge plate or plates can be fitted by adjustment for knocking or
moving sideways the sheets of paper on the feeding portion of a printing machine
for ensuring what is termed "side lay" preferably coincident as each sheet
reaches the stops ready for the grippers to carry it into the machine for being
printed.

I, FREDERICK WILLIAM VICKERY, of 14, Newcastle Street, Farringdon Street,
ity of London, Ruling Machine Maker, do hereby declare the nature of this

page_text: 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 transverse reciprocating board or boards or strips
on which a gauge plate or plates can be fitted by adjustment for knocking or

for ensuring what is termed side lay" preferably coincident as each sheet
reaches the stops ready for the grippers to carry it into the machine for being printed
The invention is chiefly intended for self feeding printing machines i.e. to
those machines in which sheets of paper are collected singly and are fed
mechnically to the stops but is applicable by slight modifications or arrange-
ments of the operating mechanism to all kinds of cylinder printing machines.
For the purpose of my invention and as shown on the annexed drawing, I fit one
or more boards or strips to move transversely in guides arranged next or near to that
portion of a cylinder printing machine where the stops are provided. This or
these boards or strips can be operated in one direction by an arm or other part
of the reciprocating table and in the reverse by a spring or springs, or it or
they can be operated from a cam on the cylinder, or from some other moving
part of the machine, and said gauge plate or plates can be employed in conjunction
with a sideboard, against which the paper can be moved for register," in
practice however the gauge plate or plates effect the true register of the paper.
A, represents an ordinary cylinder of printing machine. B, the feed table.
C, the pile of paper sheets to be printed. 1), self feeding cellular faced flop flap
on roller E as described in the Specification of a previous Patent granted to me on
the 28th January 1898, No. 2338, said flop flap roller E being operated in one
direction by the reciprocating action of the bed plate F drawing the cord G
wound over the pulley wheel H and weighted at its opposite end for the slip of the
cord when moving in the reverse direction, or by the slip of the ratchet teeth J
in the manner well known.
K, K, are endless travelling tapes on rollers L, L, said tapes occupying a posi-
tion and set at an angle for taking the sheets of paper in succession as they are
drawn from the pile by the cellular faced flop flap 1), and to convey such sheets
up to the stops M and against the gauge board N.
It often happens, that notwithstanding the care taken to adjust the feeding
appliances in printing machines, some of the sheets of paper will present them-
selves to the stops and be there retained in a slanting position as to produce
uneven printing and a distorted "register" which my present invention is intended
to obviate. For this purpose I fit the usual "lay" board V between the upper
and lower runs of the endless tapes K, K. This board V has a couple of slots
in it in which strips P, P, are fitted these strips have attached to them the knock-
ing up board W to which an end on motion is given such as by being struck by
the passing of the cam Q of the reciprocating rack bar of the travelling table F,
said cam bearing against the roller S of a strip T riding in the mid-slot U
of the board V so that the strips P. P, to which the knocking up board W is
attached can be adjustably fastened thereto by the bolt and nut X.
The strips P, P, and knocking up board W are returnable by the end
springs Y, Y, which are recessed into the board V for that purpose.
The gauge or side lay board N is affixed to lugs Z, Z, supported by the tape
carrier rods a, a, and on which they and the gauge are adjustable to suit different
widths of paper that may be passed into the printing machine.
The knocking up of the sheets of paper while on the tapes K, K, is of impor-
tance, since is ensures of each sheet being presented squarely to the stops M, M,
and consequently squarely to the gauge board N for true register of each sheet in
succession prior to its removal from the tapes by the grippers of the cylinder.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
In a printing machine, the arrangement of the knocking up or side lay board W
