Improvements relating to Means for Holding the Rib Tips of
Umbrellas, Sunshades, and the like.
I, THOMAS COLLIEU, of 6, Crouch End Hill, in the County of Middlesex, Umbrella
Manufacturer, do hereby declare the nature of this invention, and in what manner
the same 18 to be performed to be particularly described and ascertained in and by
the following statement :-
This invention relates to means for firmly holding the ribs to the sticks or tubes of
umbrellas, sunshades and the like.
Such devices as hitherto fitted to the sticks of umbrellas and the like have been
provided with a metal ring-piece which is capable of being moved longitudinally of
the stick so as to enoircle the tips of the ribs or be removed therefrom, but after a
little time the ring-piece bends or twists or becomes corroded or fixed against the
stick or the collar thereon on or over which it is intended to move and the device is
quite useless, and in some cases great difficulty is experienced in removing it from
the rib tips so as to enable the umbrella or the like to be opened.
Another device frequently used for this purpose 18 a plain india rubber ring, but
this, besides being unsightly, is placed on the stick by stretching it over the handle
and in doing so the ring is frequently overstretched, and in any case to enable it to
be placed in position the ring is made of such an elastic material that when passing
it onto the rib tips it frequently passes lower down and wears away the material of
the covering from the rib eyes.
The object of this invention is to provide means for holding the rib tips of umbrellas,
sunshades and the like, so constructed and fitted as to obviate the disadvantages
above indicated while being thoroughly efficient for its purpose, comparatively
inexpensive, simple in form, and easy of manipulation.
My invention is represented in the accompanying drawings wherein Figs. 1 and 2
are elevations showing part of an umbrella stick with my invention fitted thereto and
showing the different positions of the same, and Figs. 3 and 4 are respectively
sectional elevation and plan of the device shown in Figs. 1 and 2 on an enlarged
scale Fig. 5 18 a perspective view of the encased ring alone.
My rib tip holder consists essentially of a rubber or other elastic ring A encased in
an outer shell of metal or other rigid material B from which only a small part of the
inner periphery of the rubber or other elastic ring protrudes so as to take a frictional
grip over the rib tips. (See Figs. 4 and 5). In conjunction with this enclosed elastic
ring I may use a colla C fitted on or to the stick, said collar being provided with an
annular recess or groove c on to which the rubber or other material of the encased
ring 18 received as shown in Figure 1 when the device is removed from the rib tips
and passed over the wall o¹ of the recess or groove c. In place of the collar C a notch,
groove, recess, or projection may be cut in oi formed on the stick, or a plain ledge
may be formed thereon or the stick may be otherwise formed so as to cause the rubber
or other material of the encased ring to take a frictional grip thereon so as to hold it
in the withdrawn position shown in Fig. 1. It will be seen that the encased ring is
separate from the collar C and from the stick.

page_text: The shell of metal or other rigid material in which the elastic ring is encased will
prevent the undue stretching of the elastic ring and thereby prevent it from shipping
over and wearing the silk or other material of the cover.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim 18-
1. Means for holding the rib tips of umbrellas, sunshades, and the like, consisting
of an elastic ring encased in an outer metal or other rigid shell in combination with
a notched collar or a groove or recess on the stick substantially as and for the purpose
herein before described.
2. Means for holding the rib tips of umbrellas, sunshades, and the like, comprising
in combination an elastic ring encased in an outer rigid shell, and a collar fitted to
the stick having an annular recess or groove to receive the encased elastic ring sub-
stantially as and for the purpose hereinbefore described and illustrated in the
accompanying drawings.
3. Means for holding the rib tips of umbrellas, sunshades, and the like, comprising
in combination an elastic ring encased in an outer rigid shell and a recess, groove,
projection, or the like device formed in or fitted to the stick to receive and hold the
encased elastic ring in the withdrawn position substantially as and for the purpose
hereinbefore described.
