EDGAR EDMONDS, of the Firm of Robertson, Brooman, and Company, of
166, Fleet Street, in the City of London, Patent Agents. AN IMPROVED
ARRANGEMENT OF REVOLVING FRAME FOR UMBRELLAS, PARASOLS, AND SIMILAR
ARTICLES.". (A communication from abroad by Claude Charles Juif, of Paris,
France, Manufacturer.)
Hitherto in the construction of umbrellas, parasols, and similar articles, the silk
or other cover has been fixed immovably to the handle, so that if when the
umbrella is in use the cover should encounter or meet with any obstacle, the said
cover being more flexible than the handle, which is held in the hand, becomes bent
or twisted, often tearing the cover or causing the breakage of one or more of the
ribs. Again, when high winds prevail the cover is liable to be turned inside out.
The object of the present Invention is to obviate these accidents by providing
the umbrella cover with a movement of its own, and which is independent of the
handle, in such manner that on receiving a shock or blow it yields to the pressure
and revolves round and does not tear or split.
Likewise the force of a high wind expends itself in blowing the cover round, and
thus it cannot blow out the said cover.
According to the present Invention the stick or handle is divided into two parts,
which are united or jointed on a spindle forming a pivotting axis.
The division is preferably made near the top of the stick below the spring, or the
pin which maintains the cover when the umbrella is open.
This arrangement will now be described.

page_text: The mechanism of the Invention is composed of two principal parts, viz., a spindle
which is driven into the upper part of the stick of the umbrella, and a tube fitted
into the other part of the stick.
This tube serves as a socket or sleeve for the reception and maintenance of the
lower part of the spindle, which enters equally in length into the two parts of
the stick. At the joint of these two parts are two washers in contact, one washer
being mounted on the spindle, and the other fixed onto and forming part of the
socket.
The first washer is made preferably of iron, and the second of brass, so as to
lessen the friction and wear.
The base of the spindle projects slightly beyond the bottom of the tube, and.is
terminated by a head which is larger than the opening in the tube, thus preventing
the spindle from coming out.
-
The tube, as also the spindle, are adjusted or fitted into holes or cavities bored
out of the stick "ad hoc," and fixed by a suitable glue or cement; they may be
strengthened by screws, or by the addition of one or more pins.
Instead of using a tube or socket the mechanism may be lightened by merely
employing two rings in the interior for guiding the lower part of the spindle.
It will thus be seen that the effect of this arrangement is to guard the cover of
an umbrella against accidents and sudden shocks without the necessity of attention
being paid on the part of the user. Its employment would be very advantageous
by artists and bathers, who are frequently exposed to high winds; also for vehicles
and boats.
If when the user of this umbrella is walking rapidly along the cover should
happen to strike against an obstacle, it will yield and revolve.
In the same way the wind will merely cause it to turn round, and thus expend
its force without turning the cover inside out, as is the case at present,

EDGAR EDMONDS, of the Firm of Robertson, Brooman, and Company, of
166, Fleet Street, in the City of London, Patent Agents. "AN IMPROVED
ARRANGEMENT OF REVOLVING FRAME FOR UMBRELLAS, PARASOLS, AND SIMILAR

Hitherto in the construction of umbrellas, parasols, and similar articles, the
silk or other cover has been fixed immovably to the handle so that if when the
umbrella is in use the cover should encounter or meet with any obstacle, the said
cover being more flexible than the handle, which is held in the hand, becomes
bent or twisted, often tearing the cover, or causing the breakage of one or more
of the ribs. Again, when high winds prevail the cover is liable to be turned
inside out.
The object of the present Invention is to obviate these accidents by providing
the umbrella cover with a movement of its own, and which is independent of the
handle, in such manner that on receiving a shock or blow it yields to the pressure
and revolves round, and does not tear or split. Likewise the force of a high
wind expends itself in blowing the cover round, and thus it cannot blow out the
said cover.
According to the present Invention the stick or handle is divided into two parts,
which are united or jointed on a spindle forming a pivotting axis. The division
is preferably made near the top of the stick below the spring or the pin which
maintains the cover when the umbrella is open. This arrangement will now be
described, reference being had to the annexed Drawings.
Figure 1 is a longitudinal section through the axis of the stick or handle at the
part containing the revolving arrangement.
Figures 2 and 3 show separately in elevation and plan the spindle with its disc
or washer.
Figures 4 and 5 are two similar views of the tube which receives the spindle.
Finally, Figure 6 is a view in reduced scale of the umbrella complete, the
stick or handle being in section at the part enclosing the revolving arrangement.
It will be seen that the mechanism of the Invention is composed of two principal
parts, viz., a spindle a which is driven into the upper part A of the stick, and a-
tube b fitted into the other part B of the stick. This tube b serves as a socket or
sleeve for the reception and maintenance of the lower part of the spindle, which
enters equally in length into the two parts of the stick.
At the joint of these two parts are two washers in contact, the washer c being
mounted on the spindle, and the other d fixed onto and forming part of the socket b.
The first washer is made preferably of iron, and the second of brass, so as to lessen
the friction and wear.
The base of the spindle projects slightly beyond the bottom of the tube b, and is
terminated by a head e, which is larger than the opening in the tube, thus pre-
venting the spindle from coming out.
The tube, as also the spindle, are adjusted or fitted into holes or cavities bored
out of the stick " ad hoc," and fixed by a suitable glue or cement; they may be
strengthened by screws or by the addition of one or more pins.
Instead of using a tube or socket b the mechanism may be lightened by merely
employing two rings in the interior for guiding the lower part of the spindle. It
will thus be seen that the effect of this arrangement is to guard the cover of an

If when the user of this umbrella is walking rapidly along the cover should
happen to strike against an obstacle it will yield and revolve. In the same way
the wind will merely cause it to turn round, and thus expends its force without
turning the cover inside out, as is the case at present.
And having now described the nature of the said Invention, and in what manner
the same is to be performed, I declare that I claim on behalf of my foreign
correspondent,-
The improved arrangement of revolving frame for umbrellas, parasols, and
similar articles by which the cover of an umbrella or similar article is made
movable independently of the handle, the distinctive features of said arrangement
consisting of the combination of a spindle and a tube or socket, arranged sub-
stantially as hereinbefore described and shown in the annexed Drawings.
In witness whereof, I, the said Edgar Edmonds, have hereunto set my hand
and seal, this Twentieth day of May, One thousand eight hundred and
