page_text: LETTERS PATENT to Adrien Gros and Charles Salbreux in the Republic of
France for an Invention of "A HAT FORMING UMBRELLA OR PARASOL WHEN
REQUIRED."
PROVISIONAL SPECIFICATION left by the said Adrien Gros and Charles
Salbreux at the Office of the Commissioners of Patents on the 22nd June
1882.
ADRIEN GROS and CHARLES SALBREUX in the Republic of France "A HAT
FORMING UMBRELLA OR PARASOL WHEN REQUIRED."
The object of this invention is to produce a combined hat and umbrella or sun
shade
To this end we provide a number of ribs or stretchers which we cover with a
suitable material and connect with an arrangement of mechanism secured to the
brim of the hat. The working of this mechanism causes the ribs to extend beyond,
or withdraw over or under the hat brim.
One arrangement of this mechanism consists of a light circular metal frame
formed of two rings connected by transverse pieces and carrying a number of
pinions corresponding to the number of ribs.
These ribs are rigidly connected to the pinions so that as the pinions are
rotated tho ribs will be swung outwards or withdrawn, as the case may be.
In gear with the pinions is a toothed ring to the underside of which a button
or knob is fixed. This button or knob projects through a slot in the hat brim,
and by moving it in one direction or the other the ring will be turned and will
communicate motion to the pinions. A spring stop which takes into notches in
this ring is provided to regulate the amount of motion the ring is to receive, in
either direction.
Instead of the circular frame we may use plates to carry the pinions, which plates
are rivetted or otherwise firmly secured to the brim. In either case means aro
provided to keep the toothed ring in position
We may also employ in place of the pinions, cams, rock lovers or other suitable
means for extending the ribs.
The mechanism may be placed above or below the hat brim and will be enclosed
in any suitable manner.

Office on the 21st December 1882.
ADRIEN GROS and CHARLES SALBREUX in the Republic of France. "A HAT
FORMING UMBRELLA OR PARASOL WHEN REQUIRED'
"
The object of this Invention is to provide a combined hat and umbrella or sun
shade.
In carrying out our Invention we may use any form of hat whether made of
felt or silk
The special part which forms the umbrella or sun shade consists of a certain
number of ribs one end of each of which is pivotted to the brim of the hat.
These ribs are arranged to work horizontally and can be projected beyond the
brim or withdrawn within the width of the same and around the body of the hat
where they will be enclosed between the brim and a second brim placed above it.
A suitable material to form the cover is secured all round the body of the hat
and to the ribs and follows the movement of the ribs.
Each rib of which there may be any desired number is pivotted to one end of
a thin metal plate which is secured in any convenient manner across the brim of
tho hat.
When it is desired to open the umbrella it is only necessary to seize the point
of one rib and pull it out of the envelope in doing which all the other ribs by
reason of the tension of the covering material will be caused to follow the
movement of the first and expand the umbrella.
To close the umbrella it is necessary first to give a light pressure on the upper
brim of the hat and around the body. The brim being formed slightly conical,
acts as a spring and by the pressure the edge of the upper brim is raised and
discloses the case for containing the umbrella. One of the ribs is then turned on
its axis which causes all the other ribs to encase themselves between the two brims,
This is readily done by reason of the great space which exists at the time between
the two brims.
The brim is pressed down as soon as the umbrella is encased and the opening
is closed by an elastic ring, one edge of which is secured to the upper brim so as
to allow the ring to be turned over the edge and as it were clip the two brims
together. When this is effected the hat presents the appearance of an ordinary
bat. In order to give greater rigidity to the hat we may apply to the edge of the
brim a Ushaped metal ring which in combination with the pivot plates before
mentioned will give considerable strength without sacrificing the lightness of
the hat
In some cases we may employ mechanism for opening and closing the umbrella
in which case each rib is fixed to a small pinion. These pinions are arranged at
equal distances round a circular metal frame work and are worked by a ring which
has a number of externally toothed portions corresponding to the pinions and
which are in gear with the pinions. A sufficient amount of motion is allowed to
this toothed ring to give each. pinion about two thirds of a turn,
A spring stop or other means is employed to prevent the umbrella opening when
it is closed and closing when it is open.
The working of the ribs may be caused by other means than those just described
such as cams or levers and the moving parts may be secured to hard felt,
caoutchouc or other material as well as to a metal frame rivetted to the brim of the
hat which may be solid or perforated as desired.
As lightness is an essential condition we propose to employ any materials that
may be suitable for the purpose.

page_text: In order that our Invention shall be better understood reference is made to the
specimens shown in the accompanying drawing. Fig: 1 is a plan view of the
hat with the upper brim and covering removed so as to show the position of tho
ribs when the umbrella is closed. Fig: 2 is a similar view with the umbrella open;
Fig: 3 is a cross section of a hat with the umbrella applied thereto and taken on
the line M N Fig: 2. Figures 4.5 and 0 are detailed views on a larger scale which
will be more particularly referred to hereafter.
a. a, are the ribs which are pivotted at o to the thin metal plates r. r. These
plates are intended to give rigidity to the brim of the hat and prevent its getting
out of shape For this purpose also the brim is provided with a metal edge 8.
which consists of a U shaped metal ring.
-
c. c. is the covering which is fixed to the extremity of each rib a. a. and at
about five centimetres from these extremities as shown at b. the cover is also firmly
attached to the hat body at d.
At Figures 4 and 5 will be seen on a larger scale in sectional and plan views
the arrangement of the umbrella and brims.
The ribs a. their pivot pins. o. and the two brims A and B are shewn with great
distinctness. Each rib is flattened at its extremity a¹ in order to give more space
to make the hole, to receive the pivot pin or rivet o. A small and thin metal
washer h. is placed beneath the rib to allow of the rib moving easily on its pivot.
B is the upper brim which is formed at b. with a slightly conical portion by which
it is attached to the body of the hat in any convenient manner. The working of
this conical portion is hidden by the band g. This brim carries the elastic ring e.
which is firmly secured thereto by sewing along one edge or in any other convenient
manner. When the umbrella is open this ring is kept in the position shewn at
Fig: 4 but when the umbrella is closed this ring e. is sprung into the position
shewn at fig: 6 thereby hiding the opening and clipping, as it were, the two brims
together.
Fig: 7 shews in plan one arrangement of mechanism for opening and closing the
umbrella, the upper brim of the hat being removed.
Fig: 8. shews in plan a slight modification in the frame carrying the umbrella
and Fig: 9 is a section on an enlarged scale taken on the line 3. 4 Fig: 7 showing
the two brims and the button for working the mechanism'
A A'. are two rings of iron or other suitable material connected together by
transverse. pieces a. a. to form a framework. The ring A has eight enlargements
a. a. to receive a similar number of pinions b. which are mounted in any convenient
manner and to which the ribs L are attached. The framework is rivetted to the
brim m, of the hat and carries all the mechanism.
C is a ring which is toothed all-round or only at eight points c corresponding
to the pinions b. and resting on the transverse pieces a. a'. This ring C is
kept in place by screws e. which pass through slots c' formed in the ring. c. is a
button which is rivetted or otherwise secured to the ring, and projects through a
slot a. made in the brim of the hat. d. is a spring stop or catch which is secured
to a traverse piece a¹ and takes into notches.c³ ³ formed in the ring C so as to
hold the ring steady while the umbrella is open or closed as the case may be
The working of the mechanism is effected by pushing the button c³. in the
required direction-this moves the toothed ring C which in its turn acts on the
pinions b. and projects the ribs L as seen in fig 3.
To close the umbrella the button c². is pushed in the contrary direction.
The framework described above may be entirely suppressed and in lieu* thereof
we may use small plates of metal g. g. (see fig: 8).
