PROVISIONAL SPECIFICATION.
Improvements in or relating to Blankets for Printing Machines.
I, JOSEPH WHITE HEMMINGS, of Charles Street, Leicester, Printer, do hereby
declare the nature of this invention to be as follows:-
This invention has reference to an improved blanket for printing machines.
The invention consists of an elastic or resilient blanket or covering for the
rollers of printing and like machines the essential feature of which is a layer of
thin sheet india-rubber or equivalent composition covered on one or each of its
sides by a preferably finely woven or textile material.
This compound fabric blanket may have each of its layers cemented together
to form a fabric of single thickness and it may be cut to the size of the printing
machine cylinder to be covered and fastened in position thereon in the well
known manner.
A blanket constructed in accordance with this invention yields to any
irregularities in the face of the type bed thereby preventing embossing of the
impression and also is more durable than any of the non-elastic or non-resilient
blankets at present employed.

Improvements in or relating to Blankets for Printing Machines.
I, JOSEPH WHITE HEMMINGS, of Charles Street, Leicester, Printer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:—
This invention has reference to an improved blanket for printing machines.
The invention comprises an elastic or resilient blanket or covering for the
rollers of printing and like machines and consists of a layer of thin sheet india-
rubber or equivalent composition covered on one or each (but preferably each)
of its sides by a finely woven or textile material.
In the preferred construction I employ a finely woven fabric made from cotton
or linen threads and coat this one or more times with cement or india-rubber
solution. A thin sheet of india-rubber is then laid upon this prepared woven
fabric and another sheet of the same kind of woven fabric similarly treated may
then be placed upon the sheet rubber and the whole submitted to pressure by

page_text: passing between rollers or otherwise to compact and consolidate it and form the
three layers into a single thickness compound fabric.
This fabric, produced in the piece as described is then cut up into the required
sizes to fit or cover a printing machine roller upon which it may be fastened in
the well known manner.
A resilient blanket constructed in accordance with this invention, yields to any
irregularities in the face of the type bed thereby preventing embossing of the
impression, besides which it is more durable than any of the non-elastic or non-
resilient blankets at present employed.
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. A blanket or covering for the rollers of printing machines, consisting of a
layer of sheet india-rubber, one or each of the sides or faces of which may be
covered with a finely woven or like material substantially as described.
2. The improved resilient blanket or covering for printing machine rollers con-
structed substantially as and for the purpose hereinbefore described.
Dated this 25th day of May 1900.
