I GUSTAVE J. JACCARD, of 39, Union Square, New York, U.S. America,
Musical Instrument Manufacturer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to improvements in umbrella frames, and has for its object
to provide an article of this character which will be very durable, simple in
construction and inexpensive.
The invention will be hereinafter fully described and specifically set forth in the
annexed claims.
In the accompanying drawings forming part of this application:
Fig. 1, is a vertical sectional elevation of my improved umbrella frame showing
the samé attached to a stick or rod.
....
Fig. 2, is a plan view of the upper collar employed in a construction of my
device.
of Fig. 2.
Fig. 3, is a sectional elevation taken on a line - -x
Fig. 4, is a plan view showing the inner face of one section of the said collar,
and
Fig. 5, is a plan view showing the inner face of the other section thereof.
In constructing my improved umbrella frame, I employ a plurality of ordinary
ribs, A. These said ribs are provided' at their upper ends with solid spherical
knobs a which knobs are adapted to engage with sockets 6 of the upper collar B.
This said collar comprises a tubular portion b, which has an annular flange' 'bª
formed integrally therewith, and a detachable ring
Upon the inner face of the flange, I provide a series of semi-spherical
concavities e; and apertures d, are cut through the outer edge or periphery of the
said flange, and led into the concavities c. These said apertures terminate in
rounded portions at the vertical center of the semi-spherical concavities c.

The ring is provided upon its inner face with a series of semi-spherical
concavities
which concavities will exactly register with the concavities'c of the
flange when the two parts are assembled, whereby the spherical sockets bare
produced as illustrated in Fig. 3.
The semi-spherical concavities e of the ring 68, have leading therefrom and
terminating at the periphery of said ring, channels e' which channels exactly
register with the apertures d of the flange b.
Leading diametrically through the tubular portion 61 of the sectional upper
collar B is an aperture through which a pin g may pass for the purpose of securing
the parts of the collar together and to the stick of the umbrella.
The sliding collar B' is constructed exactly like the collar B with the exception
that the two sections and are held together by pins h. These said pins are
provided with heads ', which heads are countersunk into the interior wall of the
tube b'.
In assembling the parts, the ribs A are first supplied with the ordinary hinged
braces A¹; these said braces being provided on their lower ends with balls or
spheres a', which balls are brought into engagement with the concave apertures
of the flange The ring is then brought into engagement with the flange b
and the pins are adjusted and slightly bent to prevent their removal, as
illustrated in Fig. 1. The stick C, is then introduced through the tube b and the

page_text: upper sectional collar B is placed thereon; the balls or spheres a of the ribs A,
being placed between the two sections of said collar in a manner similar to that
described in reference to the assembling of the lower sliding collar with the
exception that a single pin G passes through the tube B1 and the stick C.
The ends of the pin G being bent, a secure fastening is provided.
The frame work of the umbrella being now completed it can be covered in the
ordinary way, and the collar B having no sharp edges or projecting ends of wire,
common in the ordinary umbrella, will afford a smooth and even surface for the
attachment of said cover, whereby the danger of ripping or tearing the same is
obviated.
The umbrella may be raised or lowered in the ordinary way and is also
susceptible to very tight folding, and it will be very much more durable than a
frame work held together by twisted wires, which wires invariably rust out
prematurely.
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 is :-
1. An umbrella frame, comprising a plurality of ribs having braces hinged
thereto, said ribs being provided with balls or spheres at their upper ends and said
braces having balls or spheres at their lower ends, and two sectional collars
mounted upon a stick or rod, the upper one of which is stationary and the lower
slidable upon said stick, which collars are provided with spherical sockets adapted
to engage respectively with the balls or spheres of the ribs and braces; substantially
as shown and described.
2. In an umbrella frame, the combination of a plurality of ribs having braces
hinged thereto, said ribs being provided with balls or spheres at their upper ends
and said braces having balls or spheres at their lower ends with two sectional
collars mounted upon a stick or rod the upper one of which is stationary and the
lower slidable upon said stick or rod, which collars are provided with spherical
sockets adapted to engage respectively with the balls or spheres of the ribs and
braces; substantially as shown and described.
3. In an umbrella frame, the combination of a plurality of metallic ribs having
braces hinged thereto said ribs being provided with spherical knobs upon their
upper ends and said braces having spherical knobs at their lower ends, and two
collars mounted upon a stick or rod, which collars comprise two sections each and
contain spherical sockets which engage with the spherical knobs of the ribs and
braces; substantially as shown and described.
