AN IMPROVEMENT IN THE MANUFACTURE OF PRINTING ROLLERS
Year: 1879

page_text: LETTERS PATENT to Robert Lanham, Managing Director of the Lanham
Printing Roller Company, Limited, of No. 75, Fleet Street, in the City of
London, for the Invention of "AN IMPROVEMENT IN THE MANUFACTURE OF
PRINTING ROLLERS."
Sealed the 18th July 1879, and dated the 2nd May 1879.
PROVISIONAL SPECIFICATION left by the said Robert Lanham at the Office
of the Commissioners of Patents on the 2nd May 1879.
ROBERT LANHAM, Managing Director of the Lanham Printing Roller Company,
Limited, of No. 75, Fleet Street, in the City of London. "AN IMPROVEMENT IN
THE MANUFACTURE OF PRINTING ROLLERS.'
"
The object of my Invention is to make a printing roller which shall be more
elastic than the ordinary roller with leather face used in lithographic printing, and
at the same time cheaper and more easily manufactured.
My Invention consists in covering the stock of the roller with a combination of
india-rubber and cloth or any suitable textile material, the cloth enabling the india-
rubber facing to be drawn over the stock and be secured in a way similar to that
of the ordinary leather covering. I now prefer to combine the india-rubber with
the cloth before drawing it over the stock; but I may find it desirable to apply
the india-rubber to the cloth when on the stock, and I now propose to place the
ordinary blanketing between the stock and my improved covering.
My improved roller will be found particularly useful for lithographic printing,
and it may also be used with advantage in typographic printing, and whether by
hand or power machines.

by the said Robert Lanham in the Great Seal Patent Office on the 30th
October 1879.
ROBERT LANHAM, Managing Director of the Lanham Printing Roller Company,
Limited, of No. 75, Fleet Street, in the City of London. "AN IMPROVEMENT IN
THE MANUFACTURE OF PRINTING ROLLERS."
Figure 1 is a side elevation of a roller embodying my Invention; Figure 2, a
transverse section on line x, x, Fig. 1.
The object of my Invention is to make a printing-roller which shall be more
elastic than the ordinary roller with leather face used in lithographic printing, and
at the same time cheaper and more easily manufactured.
My Invention consists in covering the stock of the roller with a combination of
india-rubber and cloth or any suitable textile material, the cloth enabling the
india-rubber facing to be drawn over the stock and be secured in a way similar to
that of the ordinary leather covering. This facing is shown in the Drawings as
enveloping a base consisting of a textile fabric wound tightly upon the stock.
I prefer to combine the india-rubber with the cloth before drawing it over the
stock, but I may find it desirable to apply the india-rubber to the cloth when on
the stock; and I also propose to place the ordinary blanketing between the stock
and my improved covering; but any suitable material may be placed between the
stock and the said covering.
The thickness of the india-rubber coating and of the textile fabric will vary
according to the intended use of the roller.
In the Drawings A represents the stock; a, the textile fabric; B, the rubber
covering, which consists of a seamless envelope drawn with the fabric a over the
blanketing b.
My improved roller will be found particularly useful for lithographic printing,
and it may also be used with advantage in typographic printing, and whether by
hand or power machines.
Having now described and ascertained the nature of my said Invention, and in
what manner the same is or may be performed,-
.
I claim as secured to me by the hereinbefore in part recited Letters Patent,-
The use of a printer's roller consisting of a stock A with blanketing 6 wrapped
thereon, carrying a textile fabric a, supporting throughout its length the seamless
india-rubber cover B, as herein before set forth.
In witness. whereof, I, the said Robert Lanham, have hereunto set my hand
and seal, this Thirtieth day of October, in the year of our Lord One
thousand eight hundred and seventy nine.
