PROVISIONAL SPECIFICATION.
Improvements in Machines for Printing Fabrics.
I JOHN WOOD of the Railway Foundry, Ramsbottom, in the County of
Lancaster, Machine Maker, do hereby declare the nature of this invention to be
as follows:-
My invention relates principally to the machines used in the printing of woven
fabrics. In such machines engraved rollers are used in connection with revolving
cylinders over which the fabric is passed as is well understood. For some purposes
it is of advantage that the cylinder shall be capable of horizontal adjustment.
This applies especially to the duplex machines which in each case have two
cylinders in order that the fabric can be printed upon both sides whilst passing
through the machine. In such machines there is a liability for the fabric to
contract or alter as it passes from one cylinder to the other so that the correct
register of the pattern upon the two sides of the fabric is affected. To obviate
this defect I mount the two cylinders so that they can be adjusted horizontally
in order that they may be brought close together so that the fabric may pass
instantly from one to the other. I fit the bearing blocks for the cylinder shaft to
slide horizontally in planed ways in carriages which are fitted to slide vertically
and are capable of being raised and lowered by means of screws as is usual. I
provide screws or wedge bolts or other suitable means for fixing the blocks when
adjusted. By the combination of the horizontal with the vertical adjustment
I am enabled to adjust the cylinder or each cylinder in any required direction.

Improvements in Machines for Printing Fabrics.
I JOHN WOOD of the Railway Foundry, Ramsbottom, in the County of
Lancaster, Machine Maker, 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 and accompanying drawings:-
My invention relates principally to the machines used in the printing of woven

capable of being raised and lowered by means of screws as is usual. I provide
screws or wedge bolts or other suitable means for fixing the blocks when adjusted.

In order that my invention may be fully understood I will now describe the
same more particularly, reference being had to the annexed sheet of drawings :-

page_text: The
Fig. 1 is a side elevation of a duplex or two cylinder printing machine fitted
with my improvements. The drawing shows only the outline of the frame and
the mounting and disposition of the two cylinders. The frame is marked a.
cylinders b. Each cylinder is carried on its central shaft c in bearing blocks d.
The said blocks d are mounted in carriages e which are capable of being raised
and lowered by the screws f. The carriage blocks e slide in planed ways or gaps
formed in the side of the frame as clearly shown in the drawing. Thus the vertical
adjustment of the cylinders bb is provided for. It will be noticed that the
bearing blocks d also slide in planed horizontal gaps in the carriage blocks e and
as means for adjusting these blocks horizontally provide adjusting screws g
which are screwed through the sides of the carriage blocks e and bear against the
sides of the bearing blocks d. Thus by manipulating the adjusting screws g
the bearing blocks d can be moved horizontally towards or away from each other
and the cylinders correspondingly moved. By the described means the
cylinders can be set closely together or adjusted either horizontally or vertically
as desired. It will be noted that this power of adjustment is obtained without any
alteration in the arrangement of the machine or disposition of the cylinders or
shape of the frames. When the cloth, which is represented by the thick black
line arrives at the point of contact between the two cylinders bit is nipped
and held during its transfer from one cylinder to the other and is not allowed to
shift or warp as is at present frequently the case in machines not provided with
adjusting means for setting the cylinders together.
Instead of the side adjusting screws g g for obtaining horizontal adjustment as
set forth I might use a wedging arrangement as shown at Fig. 2. Here the sides
of the bearing block d and also the ends of the gap in which it slides are made at
opposite slants and a wedge h is placed on each side of the bearing block d.
Adjusting screws g g pass through and engage with these wedges. Collars g¹ are
formed on the screws near the upper end and these collars are confined in recesses
by cap plates so that the screws g cannot shift up or down although allowed to
turn. When the screws are turned, the wedges h h are moved up or down and the
bearing block d is adjusted to one side or the other as required. Thus the same
effect is obtained as when the horizontal screws g in Fig. 1 are used. It will be
evident also that the wedges might be placed horizontally instead of vertically
and be adjusted by screws passing through snugs cast on the carriage block e.
Instead of screws or wedges I might introduce revolving cams between the bearing
block d and the ends of the gap in the carriage block e. These and other
mechanical means or substitutes would be such obvious equivalents for the screws gg
shown in Fig. 1. that I mention them only to make it plain that I am well aware
of their existence and would consider such mechanical equivalents as within the
scope of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved two cylinder machine for printing fabrics in which the cylinders
are capable of adjustment both vertically and horizontally substantially as herein-
before described and illustrated.
2. In two cylinder printing machines of the indicated type mounting the bearing
blocks of the cylinder shafts in gaps or slides in or on the vertically sliding carriage
blocks in such a manner that the said bearing blocks can be adjusted horizontally
by means of screws, wedges, cams, or other mechanical equivalents substantially as
hereinbefore described and shown.
