Year: 1862

page_text: LETTERS PATENT to John Critchley, of the City of Manchester, Manager,
in the Employ of Messieurs H. O. Newbery and Company, Manufac-
turers, for the Invention of "AN IMPROVED RIB FASTENER FOR UMBRELLAS
AND PARASOLS."
Sealed the 22nd August 1862, and dated the 29th May 1862.
PROVISIONAL SPECIFICATION left by the said John Critchley at the
Office of the Commissioners of Patents, with his Petition, on the 29th
May 1862.
I, JOHN CRITCHLEY, of the City of Manchester, Manager, in the Employ of
Messieurs H. O. Newbery and Company, Manufacturers, do hereby declare
the nature of the said Invention for "AN IMPROVED RIB FASTENER FOR UMBRELLAS
AND PARASOLS," to be as follows:-
My Invention consists in the application of a sliding bush to the stick of
the umbrella or parasol, to which bush a cupola-shaped cup is attached; the
bush is provided with a slot, forming, with a stud in the stick, a double
bayonet joint. When the umbrella or parasol, to which my improved fastener
is applied, is closed, the bush is lowered on the stick to enclose the ends of the
ribs in the cupola-shaped cup, and the bush is turned slightly round to bring
the angle part of the slot on to the stud, which retains the fastener in its
place. The fastener may be held beyond the ends of the ribs by securing the
bush in the angle slot at the other end thereof. The above details may be
modified.

by the said John Critchley in the Great Seal Patent Office on the
27th November 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
CRITCHLEY, of the City of Manchester, Manager, in the Employ of Messieurs
H. O. Newberry and Company, Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of May, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Critchley, Her special license, that I, the said John Critchley,
my executors, administrators, and assigns, or such others as I, the said John
Critchley, 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
yend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVED RIB, FASTENER FOR
UMBRELLAS AND PARASOLS," upon the condition (amongst others) that I, the said
John Critchley, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly 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.
NOW KNOW YE, that I, the said John Critchley, do hereby declare
the nature of my said 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 consists in the application of a sliding bush to the stick of
the umbrella or parasol, to which bush a cupola-shaped cup is attached; the
bush is provided with a slot, forming, with a stud in the stick, a double
bayonet joint. When the umbrella or parasol, to which my improved fastener
is applied, is closed, the bush is lowered on the stick to enclose the ends of the
ribs in the cupola-shaped cup, and the bush'is turned slightly round to bring
the angle part of the slot on to the stud, which retains the fastener in its
place. The fastener is held beyond the ends of the ribs by sliding the bush
up the stick of the umbrella or parasol and securing the angle slot at the
other end thereof to the stud in the stick.

page_text: And in order that my Invention may be fully understood and readily carried
into effect, I will proceed to describe the accompanying Sheet of Drawings,
reference being had to the figures and letters marked thereon.
Figure 1 represents part of an umbrella to which my improved rib fastener
is applied. a is the bush, fitting easily on the stick 6; the bush a is provided
with a longitudinal slot c having at each end a branch slot at right angles to
it. To the bush a is fixed the cupola-shaped cup d, and in the stick 6 is fixed
a stud e. The slot c, with its side branches, and the stud e form a double
bayonet joint. When the umbrella or parasol is closed, as shewn in Figure 1,
the bush a is lowered on the stick to enclose the ends of the ribs in the cupola-
shaped cup d, and the bush a is turned partly round to bring the upper branch
of the slot c on to the stud e, which retains the fastener in its place. When
it is requisite to open the umbrella or parasol the bush a is turned partly
round to liberate the upper branch of the slot c from the stud e; it is then
raised to bring the edge of the cupola-shaped cup d above the ends of the ribs,
and then again turned partly round to bring the lower branch of the slot c on
to the stud e, as shewn in Figure 2, which represents the umbrella with the
ribs at liberty and ready to be opened.
I wish to observe that the stick may have a metal or other collar on which
the bush may be made to work, and that the improved rib fastener may be
modified by making both branch slots at the same side of the longitudinal slot
instead of at opposite sides, as shewn; or the slot may be made in the stick,
and the stud attached to the bush a, or the bush may be made with a spiral
slot or recess fitting on a stud or spiral projection on the stick.
Having thus stated the nature of my Invention, and described the manner
of performing the same, I declare that I claim the improved rib fastener for
umbrellas and parasols, as shewn and described.
In witness whereof, I, the said John Critchley, have hereunto set my
hand and seal, this Twenty-sixth day of November, in the year of
our Lord One thousand eight hundred and sixty-two.
JOHN CRITCHLEI. (L.S.)
