Register Improver for Rotary Printing Machines.
ROBERT SANSON, Junior, Mary Villa, Canaan Lane, Edinburgh, Printer and
Phototype Engraver do hereby declare the nature of this invention to be as
follows:-
An apparatus applied to rotary printing machines for the purpose of smoothing
wavy paper, preventing thin paper from creasing and so securing improved
register."
The apparatus consists of wood or metal, tipped with rubber or other substance
having elasticity or spring. It is fastened by means of moveable screws to
underside of feed-board, and is so adjusted as to cause the rubber or other flexible
substance of the apparatus to come in contact with cylinder when the latter is put
in motion. By this means equal distribution and elimination of air are obtained,
thereby securing the result as claimed.
Dated this 28th day of November 1894.
ROBERT SANSON, Junior, Mary Villa, Canaan Lane, Edinburgh, Printer and
Phototype Engraver, 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 :-
An apparatus applied to rotary printing machines for the purpose of smoothing
wavy paper, preventing thin and other papers from creasing while being printed ;
thereby securing improved register. The apparatus (Fig. 1) consists of wood or
metal tipped with rubber, or other substance having elasticity or spring, such as
rubber, cork, steel, brass.
The apparatus is constructed of a piece of wood or metal (Fig. 1), by preference
mahogany wood, the length of the wood or metal being equal to the length of the
printing surface of the cylinder (B) of the printing machine; the breadth of the
wood or metal being six inches or thereby, and the thickness one-quarter inch or
thereby. To this wood or metal is attached, by means of glue and nails, on the
flat undersurface of its whole length, a piece of indiarubber or other flexible
substance having elasticity as before mentioned, about three inches broad, and
three-eighths of an inch or thereby in thickness. The indiarubber or other flexible
substance is attached to the wood or metal so as to leave one inch overlapping and
projecting over the whole length of the wood or metal, which when the apparatus
is fixed to the feed board (C) of the printing machine, comes in contact with the
printing cylinder (B).
The apparatus is fastened and adjusted, by means of moveable screws (A) to the
underside of feed board (C) of printing machine, and is so adjusted, by means of
said screws, as to cause the rubber or other flexible material of the apparatus to

the printing machine is put in motion. By this apparatus equal distribution and
elimination of air between printing cylinder of machine and the paper being printed,
are obtained.
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 :-
of
1. In register improver for rotary printing machines-exemption from creasing
paper,
while said
paper
is being printed.
2. Improved "register."
