Year: 1882

page_text: LETTERS PATENT to Herbert John Haddan, of Kensington, Middlesex for
an Invention of IMPROVEMENTS IN FRAMES OF UMBRELLAS AND PARASOLS
A communication to him from abroad by Conrad Neumeister of Leipzig,
Saxony.
PROVISIONAL SPECIFICATION left by the said Herbert John Haddan at
the Office of the Commissioners of Patents on the 15th September 1882.
HERBERT JOHN HADDAN of Kensington Middlesex, IMPROVEMENTS IN FRAMES
OF UMBRELLAS AND PARASOLS, a communication to me from abroad by Conrad
Neumeister of Leipzig Saxony
This invention relates to the frames, of umbrallas and parasols, and more
particularly to automatically opening. umbrellas having two sets of stretchers
It consists first in making the ribs and stretchers of such a shape, that every
stretcher lies partly in a longitudinal groove of the corresponding rib or vice-versa,
when the umbrella is closed so as to reduce the diameter of the closed umbrella, for
instance by making the ribs of T iron and the stretchers of channel-iron or a pair
of angle-irons.
Also in forming the point of the ribs by joining together the two angle-irons
of which the rib is composed and providing each point with two orifices for
the sewing-thread or other attachment. Also in hinging the outer ends of the
stretchers in automatic umbrella-frames to the underside of the rib, (web of the
T iron) without using a cap, so as to leave the outside of the rib perfectly
smooth.
Also in the application of springs to the joint of the ribs with the stretchers,
which springs retain the stretchers in the grooves of the ribs, when the umbrella is
closed, thereby preventing the unintended opening or twisting of the frame. The
said springs being secured to the ribs by means of pins & slots and pressing with
the other extremity on the hinged ends of the stretchers,

by the said Herbert John Haddan in the Great Seal Patent Office on the
13th March 1883.
HERBERT JOHN HADDAN, of Kensington, Middlesex, IMPROVEMENTS IN FRAMES
OF. UMBRELLAS AND PARASOLS, a communication to me from abroad by Conrad
Neumeister of Leipzig, Saxony,
This invention relates to the frames of umbrellas and parasols, and more
particularly to automatically opening umbrellas having two sets of stretchers.
In the following description reference will be had to Figs 1 to 12 of the
accompanying drawings
Each section of this frame consists of a rib a and of one or two stretchers b.
The improvements consist chiefly in constructing the sections of the frame of
ribs a having ends r and of stretchers 6 having ends 8, as represented in Fig. 1,
said ends being made of various constructions so as to serve either for fastening the
respective parts by wires or cords or for hinging them to their rings or notches.
The shape of the ribs and stretchers is shown by the enlarged cross sections
Figs. 4 and 8.
The ends of the stretchers are provided with a double face 8, so that the rib a
folds itself into the hollow stretcher 62 between the faces 8 as far as to reach the
fastening wire d as may be seen in Fig 2 which represents a ring f with a
stretcher 2 fastened to it and a rib a folded into the latter.
In Fig. 6 a ring f¹ is represented with a stretcher b hinged to the same by
means of pins o, and where the rib a² is completely folded up into the hollow
stretcher b.
This arrangement is also shown in Figs 3, 5, 7 and 9, of which Fig. 5 represents
a runner mounted on the stick S, and carrying a movable cup or head g and a ring f
To the latter which has the shape of a fork in cross section, are fixed the
stretchers 6 into which are folded up the ribs a.
Fig. 3 represents an attachment ring mounted on the stick with stretchers and
ribs, in cross section.
Fig. 9 represents the same as Fig 5, with the difference that the ring f is slotted
for the purpose of hinging the stretchers to the same.
Fig. 7 represents the ring f mounted on the stick, with the ribs, folded up against
the latter, shown in cross section.
In umbrella frames of this construction each rib with its stretcher fits into one of
the recesses of the attachment ring, in consequence of which the whole set of ribs
and stretchers fits closely along the stick, whereby the size of the closed umbrella
is greatly reduced in bulk and presents a smooth and neat appearance, especially
also because the ribs a are constructed without the caps k shown in Fig. 10.
Furthermore the ends r of the ribs are prevented from being twisted round the
stick when the umbrella is folded, owing to the ribs being sunk in the recesses of the
runner.
It should further be observed that owing to the shape adopted for the ribs the
umbrella frame has a smooth surface whereby the covering is not so easily worn
through and that owing to the ends of the ribs being provided with a double orifice
the covering may be more securly fastened.
Fig 10 represents a section of a frame with ribs c having the ordinary grooved
shape and with T shaped stretchers m.
Fig. 11 represents a cross section of a frame with sections of the new construction
folded together.
Fig. 12 represents a cross section of the stretchers m and ribs c on an enlarged
scale,

page_text: CLAIMS.
1. In umbrella frames the combination of ribs a having cross sections as
represented by a¹ or a³ with stretchers b or m having cross sections as shown by
bor b² and divided heads or ends & adapted to secure the stretchers to the rings f
and f1, by means of hinges, wires or equivalent attachments.
2. An umbrella frame comprising in its construction a rib a having a cross
section and an extremity r, substantially as described, stretchers b or m having
cross sections substantially as described and forked or divided extremities & adapted
to secure the stretchers in corresponding slots or notches of the attachment rings f
and f¹ by hinges, wires or equivalent means.
The whole substantially as described and illustrated.
In Witness whereof I the said Herbert John Haddan have hereunto set my
hand and seal this 13th day of March A.D. 1883.
