IMPROVEMENTS IN MACHINES FOR PRINTING FABRICS
Year: 1887

Specification Accepted, 25th Oct., 1887
1 SAMUEL KNOWLES of Tottington Works near Bury in the County of Lancaster
Calico Printer do hereby declare the nature of said Invention for IMPROVEMENTS IN
MACHINES FOR PRINTING FABRICS, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
My invention relates to the Invention for which I applied for Letters Patent
No. 12952 on the 12th October 1886 for "Improvements in machines for printing
fabrics particularly for printing sarées shawls or other fabrics with a pattern at
certain intervals.
My present improvements consist chiefly in the arrangement and application of
suitable mechanism for adjusting and setting the blocks with the cams tappets or
equivalents which intermittently operate the mechanism for lifting the engraved
printing rollers into contact with the fabric stretched on the main bowl.
And in order that my Invention may be fully understood and readily carried into
effect I will describe the accompanying Sheet of Drawings reference being had to the
figures and letters marked thereon.
Figure 1 is a side view and Figure 2 an edge view of one of the blocks in this case
with one loose tappet fitted with the aforesaid adjusting mechanism and Figure 3 is a
loose filling up piece with a recess.
In these views. a represents a cam or tappet shaft which is driven by a train of
gearing not shown from the engine as described in the Specification to my said
Application No. 12952 A.D. 1886 or in other convenient manner. On a feather
C
key a' on the shaft a is mounted a sleeve or bush on which is fitted loosely the block
or disc c which is shown in this case provided with a single tappet c¹ for operating a
roller for printing a heading or cross pattern but two or more tappets may be employed
if required to suit the pattern. On the bush b is formed a worm wheel 6 gearing with
a worm d supported and free to turn in brackets c² on the block c so that by turning
the worm d the block c can be moved round the circumference of the bush as tho
latter is prevented from turning by the feather key a'. The tappets c' are made in
different lengths according to the length of the headings or cross patterns and several
bolt holes are made in the blocks c to allow different numbers of loose tappets to be
employed.

page_text: On the face of each block c there are say two long openings or recesses which when
the blocks are used with tappets c' for operating the heading printing rollers are filled
by solid pieces c³. When however the blocks c are employed for controlling the action
of the filling rollers I prefer to dispenso with tappets c¹ and in place of the solid filling
pieces c³ shown in Figs. 1 and 2 to substitute recessed filling pieces et one of which
with a single recess is shown detached in Fig. 3.
By operating the worm d the block or disc c may be turned round the shaft a as
described to adjust the lifting mechanism so as to bring the printing roller into action
on the fabric at the point or time required to suit the pattern to be printed.
It will be readily understood that separate adjusting mechanism is required for each
block on the cam shaft.
Instead of mounting the block or disc c loosely on the sleeve or bush the block c
might be mounted loosely on the shaft and held up to the fast bush 6 by a collar or
equivalent on the shaft.
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-
1. The mechanism for adjusting and setting the blocks and tappets or recessed
filling pieces which actuate the operating mechanism for intermittently moving the
printing rollers into contact with the fabric being printed substantially as and for the
purposes herein described and as shown.
2. In a machine for printing sarees and the like a block with adjustable tappets or
recessed filling pieces as the case may be for intermittently operating the printing
rollers which block is preferably mounted loosely on a sleeve or bush keyed on the
shaft the sleeve being provided with worm teeth on its periphery engaging a worm
suitably supported on the said block substantially as and for the purposes herein
described and as illustrated by the Drawings annexed.
Dated this 22nd day of September 1887.
