page_text: I, JOHN JOHNSON, Manager, Eskbank Carpet Factory, Dalkeith, in the County of
Midlothian, North Britain do hereby declare the nature of this invention to be as
follows:
This Invention, which relates to a new or improved roller to be used in machines
whereby or wherein yarns are printed, has for its object to construct such roller so that
it shall not absorb, into its material or substance, the printing liquid or colour, and
which also shall be sufficiently durable as not to be easily or quickly injured by the
pressure of the weight or load upon it.
The Invention consists in forming the printing part of the said roller of a ring of
vulcanite, which is secured to the axle on which it rotates by a pair of flanges one on
each side of the inner part of the vulcanite ring, and through which flanges (which
also fit on the axle) screw bolts pass and these being tightened, secure all the parts
firmly together upon the said axle.
In place of using two flanges for holding the vulcanite ring between them as herein-
before described, the said ring may be held in, upon or by one flange only or the
mechanical equivalent thereof.

page_text: I, JOHN JOHNSON, Manager, Eskbank Carpet Factory, Dalkeith, in the County of
Midlothian, North Britain 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:-
My Invention, which relates to a new or improved roller to be used in machines
whereby or wherein yarns are printed, has for its object to construct such-roller so that
it shall not absorb, into its material or substance, the printing liquid or colour, and
which also shall be sufficiently durable as not to be easily or quickly injured by the
pressure of the weight or load upon it.
The Invention consists in forming the printing part of the said roller of a ring of
vulcanite, which is secured to the axle on which it rotates by a pair of flanges one on
each side, of the inner part of the vulcanite ring, and through which flanges (which also
fit on the axle) screw bolts pass and these being tightened, secure all the parts firmly
together upon the said axle.
In place of using two flanges for holding the vulcanite ring between them as herein-
before described, the said ring may be held in, upon or by one flange only, or the
mechanical equivalent thereof.
In order that my Invention may be properly understood and readily carried into
effect, I will now proceed to describe the drawings hereunto annexed.
On sheet 1 of the annexed drawings, Figure 1, is a side elevation of an improved
roller for printing yarns constructed according to my Invention.
Figure 2, is a front elevation of the same, and
Figure 3, is a transverse vertical section through the axis thereof.
In the improved printing roller the part marked A is the rings of vulcanite and to
which side pieces or rings B are fastened by pins C, or otherwise. These rings are
concentric with the printing surface of the roller A and are of such diameter
that the flanges D fit accurately within the same so that when the flanges D
and the vulcanite portions A, B, of the roller are tightened together by the
screws E all parts of the roller are concentric with the axle F. One of the flanges D
is by preference made in one piece with the axle F-whilst the other flange D is separate
thereby admitting of the inner part of the vulcanite ring A being placed between the
two flanges D, D.
Figures 4, 5 and 6 on sheet 2 of the annexed drawings are corresponding views of
my improved printing roller but in which the vulcanite part A thereof is made of a

page_text: slightly different shape and all in one piece in place of being made in separate
pieces as hereinbefore described with reference to Figures 1, 2 and 3 of the annexed
drawings.
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 constructing the printing part of the printing rollers used in yarn printing
machines of vulcanite substantially as hereinbefore described.
2. The holding of the vulcanite part of the rollers used in yarn printing machines to
the axle of such rollers by means of concentric flanges and tightening screws or by
the mechanical equivalents of such flanges or screws substantially as hereinbefore
described and shewn upon the annexed sheet of drawings.
