PROVISIONAL SPECIFICATION.
An Improved Cylinder Setting or Distancing Motion for Printing
Machines for Textile Fabrics.
JACOB BRIDGE Paradise Works Accrington, Machinist, Ironfounder, Tinplate
Worker and Coppersmith do hereby declare the nature of this invention to be as
follows:-
When printing fabrics on both sides it is desirable to bring the two cylinders as
near together as possible and to be able to remove them from each other for
purposes of lapping etc. My improvement consists in making the bushes in which
the cylinders revolve eccentric and by the application of worms and worm wheels
the cylinders are slided nearer or removed further apart from each other.

COMPLETE SPECIFICATION.
An Improved Cylinder Setting or Distancing Motion for Printing
Machines for Textile Fabrics.
JACOB BRIDGE, Paradise Works, Accrington Machinist, Ironfounder, Tinplate
Worker and Coppersmith, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention relates to what are known as duplex printing machines for textile
fabrics. In these machines it is desirable to be able to move the two large cylinders,
on the circumference of which the cloth is printed, so that the lapping of them
can be more readily effected, and in order that when this is completed the cylinders
may be brought into close contact with each other to enable the patterns on the
engraved rollers to be accurately registered on both sides of the piece in exactly
the same position. Several methods of accomplishing this object have already
been adopted none of which can be considered perfect or satisfactory.
In order that my invention may be clearly understood I will describe it
particularly by the aid of accompanying drawings.
Figure 1 is an end elevation and Figure 2 a plan in section shewing that part
of the printing machine which is affected by my invention.
A shews the slide block which is the bearing of one end of cylinder and by
means of which the cylinder is raised or lowered, the other blocks for both cylinders
are similarly dealt with so that what is described with reference to one applies
equally to the other three.
B represents a worm wheel which may have teeth entirely round the circum-
ference or only a part of the way as shewn.
C is an eccentric and D simply a brass bush in which the cylinder revolves on
its axle or centre shaft.
The worm E with the connecting shaft or centre F are so fixed to the framing
of machine that the necessary power being applied motion is given to the worm
wheel B, which in its turn moves the eccentric bush ou which it is secured, and as
this eccentric bush C is thus turned round the cylinder is moved a corresponding
distance and a setting or distancing motion obtained.
These worms and worm wheels may be so arranged as to be worked together or
separate as desired.

page_text: Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The setting together and distancing of the large cylinders in duplex printing
machines by means of an eccentric motion applied to the centres of such cylinders
and worked by means of worms and worm wheels.
2. The arrangements and combinations of parts constituting the improvements
in printing machines substantially as herein before described.
