Improvements in and in the Manufacture of Packing for Glands
and other Parts of Machinery.
I FRANK REDDAWAY of Cheltenham Street, Pendleton, in the County of Lancaster,
Manufacturer of machine belting do hereby declare the nature of this invention to be
as follows:-
My Invention relates to the material principally used in the packing of the glands
of steam engines pumps and other machinery. In the production of such packing
I in the first place manufacture a cloth composed of hair or wool or partly of hair or
wool and partly of cotton as for example the cloth may have a warp composed of hair
or wool and a weft of cotton. The cloth is woven in strips of a width suitable to my
purpose or is produced in greater widths and is cut up into strips of a suitable width.
These strips are folded several times so as to increase their thickness and the folds are
then united by means of longitudinal rows of stitches produced by a sewing machine.
The folded and stitched strips are then saturated with tallow or other suitable lubricant
or with a mixture of lubricants and are afterwards subjected to the action of rollers
in order to render the packing uniform in cross section such cross section being
round square or of other suitable form as desired. In place of the folding and
stitching I may produce the packing ready for saturation by means of a plaiting
machine yarn
made of hair or wool being used and the material being plaited in layers
to the thickness required.

I FRANK REDDAWAY of Cheltenham Street Pendleton in the County of Lancaster,
Manufacturer of Machine belting 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, that is to say :-
My Invention relates to the material principally used in the packing of the glands
of steam engines, pumps and other machinery. In the production of such packing
I in the first place manufacture a cloth composed of hair or wool or partly of hair or
wool and partly of cotton as for example the cloth may have a warp composed of hair
or wool and a weft of cotton. The cloth is woven in strips of a width suitable to my
purpose or is produced in greater width and is cut up into strips of suitable width.
The strips are folded several times so as to increase their thickness and the folds are
then united by means of longitudinal rows of stitches produced by a sewing machine.
The folded and stitched strips are then saturated with tallow or other suitable
lubricant or with a mixture of lubricanis and are afterwards subjected to the action
of rollers in order to render the packing uniform in cross section such cross section
being round, square or of other suitable form as desired. In place of the folding and
stitching I may produce the packing ready for saturation by means of a plaiting
machine, yarn made of hair or wool alone or in conjunction with cotton or cotton
yarn being used and the material being plaited in layers to the thickness required.
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 wha
I claim is
(1) The gland or machinery packing produced as herein set forth.
(2) A gland packing made from cloth of the indicated nature folded and stitched
saturated with tallow or other suitable lubricant and passed between rollers adapte
to impart the required cross-sectional shape to the packing substantially as set forth.
(3) A gland packing produced by plaiting or braiding yarns composed of hair o
wool or of mixed hair or wool and cotton or yarns of hair or wool along with cotto
yarns or yarns of mixed hair or wool and cotton along with cotton yarn in layers
the required cross-sectional form and afterwards saturating with tallow or othe
suitable lubricant substantially as set forth.
