COMPLETE SPECIFICATION filed by the said Arthur Charles Henderson at
the Office of the Commissioners of Patents on the 26th August 1882.
ARTHUR CHARLES HENDERSON of 6 Southampton Buildings Holborn in the
county of Middlesex IMPROVEMENTS IN UMBRELLA, PARASOL, AND SUN SHADE
MOUNTINGS A communication from abroad by Claudius Grataloup and Jean
Baptiste Leymarie both of 2 Boulevard de Strasbourg in the city of Paris in the
Republic of France.
This invention relates more particularly to that part of the umbrella, parasol, or
sun shade mounting which is intended to open, and keep them closed, and are
consequently intended as substitutes for the ordinary slides with check springs:
and cup slides, the inconveniences of which are well known.
The apparatus consists 1st of a slide with an upper ring or rim having notches
in it for the reception of the ends of the forked stretchers, so that these can be
bound by one and the same binding wire 2ndly of a second tube or slide adjusted
in the first, having a cap with apertures through which all the stretchers pass, and
which cap covers the first piece. These two slides glide one on the other so as to
bring the outer crown completely over the notched head or rim of the first slide
and so leave the stretchers free, or by pushing the outer crown forward, it then
presses on the stretchers and prevents them moving by keeping them close to the
stick and handle of the umbrella.
In the accompanying drawings the invention is clearly illustrated, the inventors

page_text: however do not confine themselves to the precise forms or dimensions of the parts
here represented.
Fig 1 is an external view of the umbrella mounting to which the invention refers.
Fig 2 is a section through the longitudinal axis of the new parts, in the position
they would occupy in opening the umbrella. Figs 3 to 8 are details of the
new parts.
On the handle a of the umbrella the tube b is loosely adjusted Figs 5 and 6, to
which the cap or crown c is fixed by screwing or soldering, this cap is pierced with
as many openings d, as there are stretchers to the umbrella. The tube bis furnished
below with a ring or rim e Fig 7 either screwed or soldered to it and projecting
more or less, and ornamented as desired.
:
On the slide b, a second slide g is adjusted Figs 3 and 4, with projecting rim h
at one end and the notched rim k at the upper end in this latter the ends of the
stretchers are fixed by binding wire in the usual manner; these stretchers being
connected at the forked ends to the ribs m, as is customary and in accordance with
the nature and form of the respective parts.
The rim is completely covered by the crown c. In closing the umbrella the
crown is pushed back as shown Fig 2, and meets the notched rim k in its extreme
position: after having closed the ribs by drawing down the slide in the usual
manner, take the slide in one hand and with the thumb and first finger seize the rim h
of the slide g, then push with the thumb on the rim e of the slide b, this latter
will then slide in that g, and the crown c which follows in advance presses all the
stretchers by its apertures till the stretchers are all pressed against the cane a, and
prevents their moving: in this manner the ribs m are brought close to the handle
and are there held till released by the opening of the umbrella, which is effected as
follows, by reversing the former movements, that is to say by drawing down the
slide b by the rim e, till the crown c presents its openings directly above the articu-
lations of the forked stretchers, in which case these articulations are perfectly free,
then press on the rim h, and the umbrella opens and remains so by passing what
may be termed the dead point, till it abuts upon a tube above the notched head of
the slide to which the stretchers are fixed.
Should it occur that after having placed the slides band g in the position suitable
for opening the umbrella that one accidentally pushes on the rim h, then the
stretchers may get bent, to avoid this and allow of pushing one or other of the
rims e or hindiscriminately, a spring is placed in an opening of the slide b Figs 5
and 8 which operates just below the rim h, so that if the rim e, is pushed, that h
receives the transmission of this pressure by the spring r, and replaces the slide g
in the position it would occupy as if this latter had been directly acted on.
In closing the umbrella it suffices to press gently on the spring to force it into
the aperture of the slide b so that the piece g can slide freely without obstacle
The inventors claim the slides herein described and illustrated and composed of
two tubes 1st one which directly encircles the stick of the umbrella, and which
bears a rim at one end, and a cap or crown at the other with apertures in number
equal to those of the stretchers. 2ndly of a tube which slides on the first named
one between its crown and rim, and which latter tube bears the ends of the
stretchers in its notches where they are secured in the usual manner by a binding
wire.
The stretchers pass through the openings of the crown, to reach the notched
and tubular rim inside the crown where the ends are fixed in the ordinary manner
In opening the umbrella the stretchers by passing through the apertures in the
crown are restricted in their movements as long as these openings are just above
the articulations of the stretchers and in keeping the umbrella closed the crown
being pushed forward, these apertures form a pressure on the stretchers, holding
them against the handle and preventing their moving. Claim is also made to the
flat or other spring for reproducing on the external slide the pressure exercised on
the inner one in the manner already explained and as represented Figs 5 and 8,

page_text: reservation being made to the application of this principle or any modifications of
which it is susceptible, which may be effected without departing from the principle
of action.
In witness whereof I the said Arthur Charles Henderson have hereunto set
my hand and seal this twenty eighth day of August in the Year of Our
Lord One thousand eight hundred and eighty two.
