The object of this Invention is to do away with the hand or machine sewn seams
of umbrella and other coverings, the objection to them being that when the
umbrella and so forth is wound up the overlapping seams render it thick and
clumsy, and in addition thereto, the thickness of the needle and closeness of the
stitching weakens the silk by puncture, and it frequently gives way, or the stitches
are cut by wear or by pressure on the ribs by winding up.
The feature of novelty consists in obviating the use of hand work by having
the covers of umbrellas and so on spun in the loom, the junction of the parts
being effected simultaneously with the spinning of the silk or other tissues, as the
case may be.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Arthur Charles Henderson in the Great Seal Patent Office on the
3rd April 1880.
ARTHUR CHARLES HENDERSON, of 6, Southampton Buildings, Holborn, in the
County of Middlesex. "IMPROVEMENTS IN THE MANUFACTURE OF UMBRELLA,
PARASOL, AND SUN SHADE COVERINGS." A communication from abroad by
Guillaume Otto Lies, Manufacturer, of Crefeld, Rhenish Prussia.
In the manufacture of umbrellas, parasols, and sunshades, the silk is cut in quarters
and the seams run together by machine or hand sewing. This mode of manufacture
has the disadvantage that the machine needle often frays the thread, or punctures
holes larger than requisite ; in either case a weakness of the thread and of the
tissue is the result, and where the seams are made the silk is always thicker and
prevents the rolling up of the umbrella, parasol, or sun shade as evenly and as
closely as could be desired.
This method of manufacture also necessitates two distinct operatives, one for
sewing the seams, another for fixing the cover on the frame.
By the mode of manufacture forming the subject of the present Invention these
drawbacks are obviated, and a saving of time and labour is effected, one workman
only being required to fix the cover to the frame.
The object of this Invention is to do away with the hand or machine sewn seams
of umbrella and other coverings, the objection to them being that when the
umbrella and so forth is wound up the overlapping seams render it thick and
clumsy, and in addition thereto the thickness of the needle and closeness of the
stitching weaken the silk by puncture, and it frequently gives way, or the stitches
are cut by wear or by pressure on the ribs by winding up.
The feature of novelty consists in obviating the use of hand work or machine
sewing, by having the covers of umbrellas and so on spun in the loom, the junction
of the parts being effected simultaneously with the spinning of the silk or other
tissue, as the case may be.
One of the advantages of this system is that great solidity is insured at one of
the weak points of the covering, viz., where the ends are fixed to the tips of
the ribs.
The inventor claims the new method of manufacturing umbrellas, parasols, and
sun-shade coverings, the seam being made at the time of spinning the silk or other
tissue. As this method is a kind of ornamentation one or more threads may be
used specially with this view. He also claims the manufacture of other materials
by this method where such mode of manufacture is advantageous.
In witness whereof, I, the said Arthur Charles Henderson, bave hereunto
set my hand and seal, this Thirtieth day of March, in the year of our
Lord One thousand eight hundred and eighty.
