IMPROVEMENTS IN STICKS FOR UMBRELLAS AND SUNSHADES
Year: 1880

page_text: LETTERS PATENT to Charles Denton Abel, of No. 28, Southampton Buildings,
Chancery Lane, in the County of Middlesex, for an Invention of "IMPROVEMENTS
IN STICKS FOR UMBRELLAS AND SUNSHADES." A communication from
abroad by Messrs. Baumgarten and Mensendieck, of Hamburg, in the German
Empire.
PROVISIONAL SPECIFICATION left by the said Charles Denton Abel at the
Office of the Commissioners of Patents on the 18th October 1880.
CHARLES DENTON ABEL, of No. 28, Southampton Buildings, Chancery Lane, in
the County of Middlesex. "IMPROVEMENTS IN STICKS FOR UMBRELLAS AND
SUNSHADES." [A communication from abroad by Messrs. Baumgarten and
Mensendieck, of Hamburg, in the German Empire.]
According to the present Invention sticks for umbrellas and sunshades are
constructed of a metal tube, upon which is secured a coating or covering of ebonite
or vulcanite. By this means the sticks can be made thinner, lighter, and more
durable than if made of ebonite alone, while they possess the advantage of appearing
to be made entirely of that material.
For the above purpose the manufacture is, by preference, carried out as follows:-
A tube of iron, or other suitable metal, has first a thread of twine wound helically
along its whole length, and has its surface coated with glue or other suitable
cement. To this is then applied a thin veneer of ebonite, which is, by preference,
previously heated in order to render it sufficiently flexible to enable it to be readily
wrapped round the metal tube. A wrapping of this is then applied with suitable
pressure in any convenient known manner until the ebonite covering has cooled
and become firmly fixed to the tube.

the County of Middlesex. "IMPROVEMENTS IN STICKS FOR UMBRELLAS AND
SUNSHADES." A communication from abroad by Messrs. Baumgarten and
Mensendieck, of Hamburg, in the German Empire.
According to the present Invention sticks for umbrellas and sunshades are
constructed of a metal rod or tube upon which is secured a coating or covering of
ebonite or vulcanite. By this means the sticks can be made thinner, lighter, and
more durable than if made of ebonite alone, while they possess the advantage of
appearing to be made entirely of that material.
For the above purpose the manufacture is, by preference, carried out as
follows:-
A tube of iron, or other suitable metal, has first a thread of twine wound helically
along its whole length, and has its surface coated with glue or other suitable
cement. To this is then applied a thin vencer of ebonite,, which is, by preference,
previously heated in order to render it sufficiently flexible to enable it to be readily
wrapped round the metal tube. A wrapping of this is then applied with suitable
pressure in any convenient known manner until the ebonite covering has cooled
and become firmly fixed to the tube. A convenient way of doing this consists in
entirely covering the ebonite or other veneer (after wrapping it on the tube) with
a layer of thread temporarily wound over it in a helical way. This is removed
only after the ebonite is firmly set or fixed.
Having thus described the nature of the said Invention, and in what manner the
same is to be performed, as communicated to me by my foreign correspondents, I
claim,―
The herein described improved manufacture of sticks for umbrellas and sunshades
consisting of a rod or tube of metal, having cemented thereto a veneer of ebonite
or vulcanite.

In witness whereof, I, the said Charles Denton Abel, have hereunto set my
hand and seal, this Sixteenth day of April, in the year of our Lord One
thousand eight hundred and eighty one.
