DAVID ELKAN, of the Firm of Jacobs and Company, of Finsbury, in the
County of Middlesex. "IMPROVEMENTS IN UMBRELLA TIP FASTENERS.”
My Invention relates to improvements in umbrella tip fasteners or caps, and con-
sists in making the fastener or cap in the form of a cylindrical tube or sleeve which
slides over a ferrule or band fixed round the umbrella handle at its junction with
the stick or other suitable part. Across the middle or other convenient part of this
cylindrical tube or sleeve is fixed an annular partition, plate, or ring sliding on or
over an inner tube projecting from the fixed ferrule or band, and terminating at its
inner end in a plate or washer, through the centre of which and through the inner
tube passes the umbrella stick.
Inside the cylindrical tube or sleeve and round the outside of the inner tube,
between the shoulder of the fixed ferrule or band and the partition plate or ring, is
placed a spiral spring, the action of which constantly tends (unless otherwise
constrained) to force the cylindrical tube or sleeve over the tips of the umbrella
ribs.
When required to release the cylindrical tube or sleeve from the tips it is forced
back by the fingers along the fixed ferrule or band towards the umbrella handle,
the spring being thereby compressed so as to force the cylindrical tube or sleeve
over the tips again when required.
In order to lock the cylindrical tube or sleeve or prevent its being forced by the
spiral spring over the tips when the umbrella is required for use, I fix to any con-
venient part of the outside of the cylindrical tube or sleeve a flat steel or other

page_text: spring, over which is placed a double lever or trigger hinged to a fulcrum on the
tube or sleeve and formed on the under side of its inner end with a tooth or pro-
jection which takes into a hole in the tube or sleeve and operates in such a manner
that when the latter is forced back so as to uncover the tips of the umbrella the
tooth or projection is forced by the flat spring through the said hole, and immediately
behind the plate or washer on the end of the inner tube, against which-it-
catches.
By this means the cylindrical tube or sleeve is securely locked in that position.
Or if preferred the tooth or projection may be made to take into a hole formed in
the formule ^r hand higher un towards the handle in lieu of catching behind the
spring, over which is placed a double lever or trigger hinged to a fulcrum on the
tube or sleeve and formed on the under side of its inner end with a tooth or pro-
jection which takes into a hole in the tube or sleeve and operates in such a manner
that when the latter is forced back so as to uncover the tips of the umbrella the
tooth or projection is forced by the flat spring through the said hole, and immediately
behind the plate or washer on the end of the inner tube, against which-it-
catches.
By this means the cylindrical tube or sleeve is securely locked in that position.
Or if preferred the tooth or projection may be made to take into a hole formed in
the formule or band higher up towards the handle in lieu of catching behind the
plate or washer.
On depressing the outer arm of the lever or trigger with the thumb the tooth or
projection is released from the hole in the cylindrical_tube or sleeve, which is then
forced by the spiral spring over the tips of the umbrellas as required.
In order to retain the polish given to the ferrule or band I form it at is inner end
with a burred edge, which takes the friction of the sliding tube or sleeve and pre-
vents it from rubbing the ferrule or band.

County of Middlesex. "IMPROVEMENTS IN UMBRELLA TIP FASTENERS."
My Invention relates to improvements in umbrella tip fasteners or caps, and is
illustrated by the accompanying Drawing, whereon Fig. 1 is a sectional view of one
form thereof, and Fig. 2 a similar view of a modified arrangement, like letters of
reference indicating corresponding parts in both Figures.
It consists (as shewn in Figure 1) in making the fastener or cap in the form of a
cylindrical tube or sleeve A, which slides over a ferrule or band B fixed round the
umbrella handle C, at its junction with the stick D or other suitable part. Across
the middle or other convenient part of the cylindrical tube or sleeve A is fixed an
annular partition plate or ring a sliding on or over an inner tube b projecting from
the fixed ferrule or band B and terininating at its inner end in a plate or washer E,
through the centre of which and through the inner tube b passes the umbrella
stick D.
Inside the cylindrical tube or sleeve A, and round the outside of the inner tube b,
between the shoulder of the fixed ferrule or band B and the partition plate or ring a
is placed a spiral spring F, the action of which constantly tends (unless otherwise
constrained) to force the cylindrical tube or sleeve A over the tips of the umbrella
ribs.
When required to release the cylindrical tube or sleeve A. from the tips it is forced
back by the fingers along the fixed ferrule or band B towards the umbrella handle C,
the spring F being thereby compressed so as to force the cylindrical tube or sleeve A
over the tips again when required.
In order to lock the cylindrical tube or sleeve A, or prevent its being forced by
the spiral spring F over the tips when the umbrella is required for use, I fix to any
convenient part of the outside of the cylindrical tube or sleeve A a flat steel or other
spring G over which is placed a double lever or triangle H hinged to a fulcrum on
the tube or sleeve and formed on the under side of its inner end with a tooth or
projection & which takes into a hole in the tube or sleeve A. and operates in such a
manner that when the latter is forced back so as to uncover the tips of the umbrella
the tooth or projection d is forced by the flat spring G through the said hole, and
immediately behind the plate or washer E against which it catches. By this means
the cylindrical tube or sleeve A is securely locked in that position, or, if preferred,
the tooth or projection & may be made to take into a hole formed in the ferrule
or band higher up towards the handle in lieu of catching behind the plate or
washer E.
On depressing the outer arm of the lever or trigger H with the thumb the tooth
or projection d is released from the hole in the cylindrical tube or sleeve A, which
is then forced by the spiral spring F over the tips of the umbrella as required.
In order to retain the polish given to the ferrule or band B, I form it at its inner
end with a burred edge, which takes the friction of the sliding tube or sleeve A. and
prevents it from rubbing the ferrule or band B.
In the modified form of my Invention as seen in Fig. 2 a spiral spring G¹ placed
in a nipple piece (or otherwise secured) between the tube or sleeve A and the outer
end of the lever H' is substituted for the flat spring G (Fig. 1), and the outer end
of the lever H is made shorter than that of the lever H (Fig. 1), thereby producing
a neater and more compact arrangement.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I consider novel and original, and

page_text: therefore claim as the Invention secured to.me by the herein-before in part recited
Letters Patent is,―
The construction and arrangement of umbrella tip fasteners, substantially as
herein-before described, and illustrated by the accompanying Drawing.
In witness whereof, I, the said David Elkan, have hereunto set my hand
and seal, this Twenty-fourth day of April, in the year of our Lord One
thousand eight hundred and seventy-nine.
