PROVISIONAL SPECIFICATION
Improvements in the Construction of Umbrellas and Sunshades.
I, JOHN BUCKLEY SEEL of 66 Basinghall Street in the city of London, Commission
Agent do hereby declare the nature of this invention to be as follows:
My invention relates to improvements in the construction of ventillated umbrellas.
I take an umbrella frame of the ordinary construction, a short distance from the notch
end I attach an additional short stretcher to each rib, the other ends of these stretchers
I attach to a runner or notch sliding freely on the stick: I now take an additional
small frame with the ribs say of about one third the length of the principal ones, and
the stretchers rather longer than would be usually attached to ribs of these sizes, these
stretchers I attach to the same runner or notch to which the small stretchers attached
to the ordinary frame before described are secured; this runner or notch being pro-
vided with a sufficient number of cuts or nicks to receive them; the ends of the ribs
of this auxilliary frame are secured to a notch attached to the stick a short distance
above the ordinary one: the small auxilliary frame is covered in the usual manner,
but in the large umbrella an opening in the cover a few inches less than the diameter
of the auxilliary umbrella is left round the notch, the top end of each seam being
secured to an eyelet placed on each rib for that purpose.
The action is as follows:-
The umbrella being closed, if the runner is pushed upwards the small stretchers
attached to the principal ribs raise the movable notch or runner to which the
stretchers of the auxilliary umbrella are also attached, thus causing the auxilliary
umbrella to be opened simultaneously with the largo one, and in closing the reverse
action takes place, the stretchers and ends of ribs of auxilliary umbrella fitting in
between the ribs of the large frame, thus causing very little extra bulk when
closed.
The auxilliary umbrella is to be placed at such a distance above the principal one,
that a current of air can pass through the opening in the top of the latter.

COMPLETE SPECIFICATION.
Improvements in the Construction of Umbrellas and Sunshades.
I JOHN BUCKLEY SEEL of 66 Basinghall Street in the City of London Comission
Agent 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:-
My invention relates to improvements in the construction of ventilated umbrellas.
I take an umbrella frame of the ordinary construction which I will call the principal
frame. I attach an additional short stretcher to each rib at a short distance from the
end of such rib nearest to the notch. The other ends of these stretchers I attach to a
runner or moveable notch sliding freely on the stick between the ordinary fixed notch
and the ordinary runner. The stick is made longer than usual so as to project several
inches further than usual beyond the ordinary fixed notch. I now take an additional
small frame which I will call the supplemental frame with the ribs of about one third
the length of the ribs of the principal frame and the stretchers rather longer than
would be usually attached to ribs of the size of those of the supplemental frame.
The stretchers of the supplemental frame I attach to the same runner or moveabio
notch to which the smaller stretchers of the principal frame are attached this runner

page_text: or moveable notch being provided with a sufficient number of cuts or nicks to receive
both the stretchers of the supplemental frame & the shorter stretchers of the principal
frame arranged alternately so that the stretchers of the supplemental frame and with
them the ribs of the same fraine work between the stretchers and ribs of the principal
frame.
The ribs of the supplemental frame are secured to an ordinary notch attached to
the stick a short distance above the ordinary fixed notch of the principal frame.
The supplemental frame is covered in the usual manner but in the cover of the
principal frame an opening a few inches less in diameter than the supplemental or
auxiliary umbrella is left round the notch the top end of each seam being secured to
an eyelet placed on each rib of the principal frame for that purpose or instead of an
eyelet a fillet or other small projection may be made upon the rib and the cover
stitched round the rib above such projection.
The construction and arrangement of the parts of an umbrella made according to
my invention may be more fully understood by reference to the drawings accompanying
this specification.
Similar parts are indicated by the same letters.
Fig. 1. is an elevation of the umbrella when open but with all the ribs and stretchers
removed (for clearness of illustration) except two ribs of the principal and two of the
supplemental frame with their corresponding stretchers.
Fig. 2. is an elevation of one of the ribs (with its two stretchers) of the principal
frame.
Fig. 3 is a top plan of the ribs of the complete umbrella showing the alternate
arrangement of the ribs of the principal and supplemental umbrellas.
Fig. 4. is a horizontal section through the dotted line K. K. in Fig. 1. shewing the
alternate arrangement of the stretchers of the supplemental frame & the shorter
stretchers of the principal frame.
A is the ordinary runner; B B are the ordinary stretchers of the principal frame;
CC are the ribs of the principal frame; D, D, are the shorter stretchers attached to
such ribs & to the runner or moveable notch E; F F are the stretchers of the supple-
mental frame attached to the ribs H H and also to the moveable notch E; G is the
fixed notch to which the ribs of the principal frame are attached; I is the fixed notch
to which the ribs H H of the supplemental frame are secured and J J are the eyelets
fixed to the principal ribs for the purpose of securing the top ends of the seams of the
principal cover.
The action is as follows:-
The umbrella being closed if the runner A is pushed upwards the smaller
stretchers D D attached to the principal ribs raise the runner or moveable notch E to
which the stretchers F F of the supplemental or auxiliary umbrella are also attached
thus causing the supplemental or auxiliary umbrella to be opened simultaneously with
the large or principal one and in closing the reverse action takes place the stretchers
and ends of the ribs of the supplemental or auxiliary umbrella fitting in between the
ribs of the large or principal frame thus causing very little extra bulk when
closed.
The supplementary or auxiliary umbrella is to be placed at such a distance above
the principal one that a current of air can pass through the opening in the top of the
latter.
I am aware that ventilated umbrellas have been constructed by fixing a supplemental
frame above the principal frame and leaving a hole in the cover of the principal frame
of somewhat less than the diameter of the supplemental frame and I do not claim that
part of the arrangement above described as part of my invention. I am also aware
that various contrivances have been resorted to for the purpose of effecting the
simultaneous opening & closing of the supplemental and principal umbrellas such as
.attaching the ribs of the supplemental frame to the ribs or stretchers of the principal
frame by links and I do not claim any such contrivances all of which have proved
more or less unsatisfactory in practice but having now particularly described and

page_text: ascertained the nature of my said invention & in what manner the same is to be
performed I declare that what I claim is :-
1. In ventilated umbrellas or sunshades secondary stretchers attached to the ribs of
the principal frame and to a runner or moveable notch sliding freely on the stick
between the ordinary runner and the ordinary notch of the principal frame to which
the stretchers of the supplemental frame are also attached substantially as hereinbefore
described.
2. In a ventilated umbrella or sunshade the runner or moveable notch E sliding
freely on the stick between the ordinary runner and fixed notch of the principal frame
substantially as hereinbefore described.
3. In a ventilated umbrella or sunshade the rib of the principal frame with two
stretchers attached to it substantially as hereinbefore described.
