IMPROVEMENTS IN TUBES FOR VACUUM AND OTHER RAILWAY BRAKES."
Year: 1880

page_text: LETTERS PATENT to Charles Moseley, of Manchester, in the County of
Lancaster, for an Invention of "IMPROVEMENTS IN TUBES FOR VACUUM AND
OTHER RAILWAY BRAKES."
PROVISIONAL SPECIFICATION left by the said Charles Moseley at the
Office of the Commissioners of Patents on the 14th October 1880.
CHARLES MOSELEY, of Manchester, in the County of Lancaster.
MENTS IN TUBES FOR VACUUM AND OTHER RAILWAY BRAKES."
" IMPROVE-
My Invention consists in an improved construction of the connecting flexible
tubes, and in the construction of the compressing tubes for vacuum and other
railway brakes.
The ordinary connecting tube is made by folds of woven cloth with a lining of
india rubber, which in practice fails to give the necessary amount of flexibility.
In order to obtain perfect flexibility and elasticity I cover the inner lining of
india rubber with linen or cotton in a spiral, knitted, or plaited form, in one or
more coverings as may be desired, each separate cover being coated with india
rubber. In this manner I make a tube which is seamless, and much more durable
and Blexible than the ordinary tubes.
The compressing tube is usually made by covering iron rings with india rubber
and cloth in the form of a tube; and my improvement consists in the use of discs
of metal with holes in the centre rather larger than the rod which passes through
the tube instead of rings; also in forming the outer covering of a knitted or plaited
fabric, which enables me to obtain more motion in the compression than can be
attained when a woven cloth is used.

by the said Charles Moseley in the Great Seal Patent Office on the 13th April

"IMPROVE-
My Invention consists in an improved construction of the connecting flexible
tubes, and in the construction of the compressing tubes for vacuum and other
railway brakes.
The ordinary connecting tube is made by folds of woven cloth with a lining of
india rubber, which in practice fails to give the necessary amount of flexibility.
In order to obtain perfect flexibility and elasticity I cover the inner lining of
india rubber with linen or cotton in a spiral, knitted, or plaited form, in one or
more coverings as may be desired, each separate cover being coated with india
rubber.
In this manner I make a tube which is seamless, and much more durable and
flexible than the ordinary tubes.
The compressing tube is usually made by covering iron rings with india rubber
and cloth in the form of a tube; and my improvement consists in the use of discs
of metal with holes in the centre rather larger than the rod which passes through
the tube instead of rings; also in forming the outer covering of a knitted or
plaited fabric, which enables me to obtain more motion in the compression than
can be attained when a woven cloth is used.
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.
Fig. 1 represents a portion of a connecting flexible tube, made according to my
Invention, with the linen or cotton covering exposed. This covering is made on
the tube by a knitting or plaiting machine, and forms a continuous, seamless,
circular web or tube of fabric, each thread being carried round and round the tube
spirally. The threads may intersect each other as frequently as may be desired to
form the tubular covering.
Fig. 2 shows a cross section of a connecting flexible tube made according to my
Invention, in which is a distending wire of the ordinary construction. The circles
in dotted lines indicate my improved knitted or plaited coverings. There are two
of these coverings round the flexible tube, and each covering is coated with india
rubber. The covering is plaited on the tube by an ordinary plaiting machine, the
tube being drawn up through the centre of the machine as the covering is formed.
Fig. 3 shows a portion of a compressing tube, partly in section, made according
to my Invention. The discs for distending the tube are marked a, and in the
centre of each disc is a hole for the rod to pass through. The tube has three
coverings of seamless knitted or plaited fabric; each covering is coated with india-
rubber. The dotted lines indicate the knitted coverings. These coverings are
knitted by a knitting machine in the form of a tube, and drawn on to the india
rubber tubular lining.
Each successive knitted covering being coated with india rubber the depressions
giving the bellows form to the tube being obtained by a compressing ring during
the process of vulcanization.
Fig. 4 is a front view of a disc; the hole in the centre is rather larger than the
rod which passes through the compressing tube.
The tubes thus formed are seamless, and possess equal strength and elasticity
throughout.

page_text: Having stated the nature of my Invention, and described the manner of per-
forming the same, I would have it understood that I do not limit myself to the
details given, as they may be varied or modified; and what
I claim is,―
The use and application for vacuum and other brakes of seamless flexible india
rubber tubes, as herein described and set forth.

In witness whereof, I, the said Charles Moseley, have hereunto set my hand
and seal, this Twelfth day of April, One thousand eight hundred and
eighty one.
