page_text: LETTERS PATENT to John Sangster, of Cheapside, in the City of
London, for the Invention of "IMPROVEMENTS IN UMBRELLAS AND
PARASOLS."A communication.
Sealed the 16th March 1853, and dated the 25th January 1853.
PROVISIONAL SPECIFICATION left by the said John Sangster at
the Office of the Commissioners of Patents, with his Petition,
on the 25th January 1853.
I, JOHN SANGSTER, of Cheapside, in the City of London, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN
UMBRELLAS AND PARASOLS" to be as follows:-
This Invention is applicable to the sticks of umbrellas and
parasols, which are made to fold in their length; and this In-
vention consists of connecting the two parts of a stick by means of
an intermediate or connecting piece and two knuckle or pin joints,

page_text: over which an outer tube is placed with slits in it to correspond
with the joints, so that when the slits in the tube correspond with
or are opposite to the joints the joints can be folded; but when
the slits are moved away from the joints, by turning the tube partly
round, no folding of the joints can take place.
SPECIFICATION in pursuance of the conditions of the Letters
Patent, filed by the said John Sangster in the Great Seal
Patent Office on the 25th July 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOHN SANGSTER, of Cheapside, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of January, in
the year of our Lord One thousand eight hundred and fifty-three,
in the sixteenth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said John Sangster, Her
special licence that I, the said John Sangster, my executors, ad-
ministrators, and assigns, or such others as I, the said John
Sangster, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN UMBRELLAS AND PARASOLS,"
communicated to me by a certain foreigner, upon the
dition (amongst others) that I, the said John Sangster, by an
instrument in writing under my hand and seal, should parti-
enlarly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters
Patent.

page_text: NOW KNOW YE, that I, the said John Sangster, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof (that is to say):
This Invention is applicable to the sticks of umbrellas and
parasols, which are made to fold in their length; and this In-
vention consists of connecting the two parts of a stick by means of
an intermediate or connecting piece and two knuckle or pin joints,
over which an outer tube is placed with slits in it to correspond
with the joints, so that when the slits in the tube correspond with
one opposite to the joints, the joints can be folded; but when the
slits are moved away from the joints (by turning the tube partly
round) no folding of the joints can take place. And in order that
my said Invention may be most fully understood, and readily carried
into effect, I will proceed to describe the means pursued by inc.
DESCRIPTION OF THE DRAWING.
Figure 1, shows part of a stick of an umbrella or parasol in the
folded state; Figure 2, shows the stick when opened out; Figure 3,
shows a like view, but the tube with slits is partly in section; and
Figure 3, shows two views of the tube separately; a, b, are the two
parts of the stick, each of which is connected by a knuckle or pin
joint d to an intermediate piece c; on each of the parts a, b, of
the stick there is a ferule d', by which the parts of the knuckle
or pin joints d are formed as shewn; e, is a tube having two slits
in it corresponding to the parts d² of the pin joints, so that when
the tube e is turned round so as to coincide with the joints those
joints will fold, but when the tube e is turned in such manner that
the slits do not coincide with the joints, those joints will be prevented
folding. The tube e is turned by pressing against the projection
el, the stem of which screws through the tube e into and moves in
a groove formed in the intermediate piece, as shown.
Having thus, described the nature of my Invention, and the

page_text: manner of performing the same, I would have it understood that
what I claim is, the combination of parts herein described.
In witness whereof, I, the said John Sangster, have hereunto
set my hand and seal, this Twenty-fifth day of July, in the
year of our Lord One thousand eight hundred and fifty-
three
Witness,
W. TONGUE.
JOHN SANGSTER. (L.S.)
