page_text: I, DANIEL WILKINS FESSEY, of 1 Worship Street, London, E.C. Machinery
Salesman do hereby declare the nature of the said 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 relates to the lubricating coating or covering of yarn formed of
cotton, hemp, fax, jute, or other suitable material with wax, tallow, pitch or the
like for the manufacture of sewing threads intended more especially for use in
sewing leather or other thick substances.
Hitherto sewing threads lubricated or coated with wax, tallow, pitch or other
suitable material have been usually coated or covered with the said material after
being twisted by means of suitable machinery. The result of this is that the wax,
tallow, pitch or other material remains upon the outside or exterior of the said sewing
threads, or only penetrates to a slight extent into the latter, thus to some extent
defeating tho object for which the said wax, tallow pitch or other material is
employed.
The main object of my said invention is to obviate the above defect and to
provide for coating or covering the said sewing thread with wax, tallow, pitch or
other suitable material in such a manner that the said coating or covering will
not be entirely or almost entirely upon the outside or exterior part thereof.
In carrying my said invention into practice I pass the strands of yarn from
which the sewing thread is intended to be manufactured, and previous to the
operation of twisting, through wax, tallow, pitch, or other suitable material either
in a hot or melted condition, or cold and contained in any suitable receptacle.
After being coated or covered as above described the said strands are forthwith
twisted in the usual manner by mechanical means.
I sometimes twist the strands while they are passing through the wax, tallow,
pitch or other material but after they have become sufficiently saturated or
covered therewith.
In applying my said invention to an ordinary machine for twisting cord, twine
or sewing thread I prefer to employ a receptacle or trough of any convenient
form provided with a nipper or other suitable device for carrying the strands of
yarn. I place this trough or receptacle in any convenient position between the
bobbin or spool carrying the untwisted yarn and the bobbin or spool receiving the
twisted thread so that the yarn can run through the wax or other material in single
strands or in a doubled but untwisted condition, and he twisted immediately after it is
thoroughly waxed in all its strands.
It is obvious that I can apply my said invention to any well known form of machine
for twisting cord, twine or thread,

page_text: 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 :
The manufacture of thread for sewing leather or other heavy material, by first
coating or covering the strands of yarn with wax, tallow, pitch or similar
material and then twisting the said strands to form the thread substantially as
above described.
