IMPROVEMENTS IN UMBRELLA Tip CAPS
Year: 1873

page_text: LETTERS PATENT to David Elkan, of Finsbury Square, in the County
of Middlesex, for the Invention of "IMPROVEMENTS IN UMBRELLA Tip
CAPS,"
PROVISIONAL SPECIFICATION left by the said David Elkan at the
Office of the Commissioners of Patents, with his Petition, on the
21st October 1873.
I, DAVID ELKAN, of Finsbury Square, in the County of Middlesex,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
UMBRELLA TIP CAPS," to be as follows:-
:-
This Invention relates to a device for keeping the ribs of an umbrella
close to the stick when not in use.
Heretofore these caps have worked upon a sleeve or band of metal
encircling the stick and secured thereon; and great inconvenience has
been experienced by the said caps working loose and releasing the
umbrella rib tips.

page_text: Now my improvements consist in securing upon the sleeve fitting the
stick a second sleeve of larger diameter, thus forming a receptacle for a
spiral spring. The "tip cap" is formed on a sleeve or short tube, which
is passed over the inner sleeve between it and the outer one, forming the
receptacle for the spiral spring, which spring acts upon the upper edge
of the sleeve of the cap. A slot (L shaped) is made in the sleeve of the
cap, and a pin or stud is passed through the said slot and secured to the
inner and outer sleeve. The lower edge of the inner sleeve is "burred"
to keep the "tip cap" and the inner and outer sleeves together.
The tip cap constructed as above described is secured upon the stick
in such position that when the power of the spring is exerted the cap
shall encircle the rib tips.
To release the ribs the cap is pressed back upon the spring and turned
so that the stud shall occupy a position in the horizontal cut of the L shaped
lot, thus retaining the cap until it is again required to secure the rib tips.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said David Elkan in the Great Seal Patent Office on
the 21st April 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
ELKAN, of Finsbury Square, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of October, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said David Elkan, Her special licence that.
I, the said David Elkan, my executors, administrators, and assigns,
or such others as I, the said David Elkan, my executors, adminis-
trators, 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 UMBRELLA
TIP CAPS," upon the condition (amongst others) that I, the said David
}

page_text: Elkan, my exécutors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should par-
ticularly 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.
1.
NOW KNOW YE, that I, the said David Elkan, 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, reference being had to the accompanying Sheet of
Drawings and to the figures and letters marked thereon, that is to
say:
This Invention relates to a device for keeping the ribs of an umbrella
close to the stick when not in use.
.!
Heretofore these caps have worked upon a sleeve or band of metal
encircling the stick and secured thereon, and great inconvenience has
been experienced by the said caps working loose and releasing the
umbrella rib tips..
Now my improvements consist in forming upon or securing to the
sleeve fitting the stick a second sleeve of larger diameter, thus forming a
receptacle for a spiral spring. The "tip cap" is formed on a sleeve or
short tube which is passed over the inner sleeve between it and the outer
one forming the receptacle for the spiral spring, which spring acts upon
the upper edge of the sleeve of the cap. A slot (L shaped) is made in
the sleeve of the cap, and a pin or stud is passed through the said slot
and secured to the inner and outer sleeve. The lower edge of the inner
sleeve is "burred" to keep the "tip cap" and the inner and outer sleeves
together.
In the accompanying Drawings Fig. 1 is a view of the device complete;
Fig. 2, a plan; Fig. 3, a section at line X, X, of Fig. 2; and Figs. 4 and
5, views of detached parts.
a is the sleeve fitting the stick; b, the second sleeve, secured
upon (or
forming part of) sleeve a; c, the receptacle formed by the two sleeves a
and b; e, the tip cap; d, the spring which acts upon the upper edge of
the sleeve of the cap; and f, the "burr" formed on the lower edge of
the sleeve a to keep the tip cap and the inner and outer sleeves together.
The L shaped slot is shown in Fig. 1.

page_text: The tip cap constructed as described is secured upon the stick in such
position that when the power of the spring is exerted the cap shall
encircle the rib tips.
To release the ribs the cap is pressed back upon the spring and turned
so that the stud shall occupy a position in the horizontal cut of the 1
L shaped slot, thus retaining the cap until it is again required to secure
the rib tips.
Having thus described the nature and particulars of my said Invention
I claim, the improvements in umbrella tip caps, substantially as herein
described and shown by the Drawings.
In witness whereof, I, the said David Elkan, have hereunto set my
hand and seal, this Fifteenth day of April, in the year of our Lord
One thousand eight hundred and seventy-four.
