Improvements in or relating to the Folding of Umbrellas, Tents,.
Carriage Heads, and the like.
I, EDWIN RUCK KESTERTON, of No. 14 Nightingale Lane, Balham, in the
County of London, Coach Builder, do hereby declare the nature of this invention
to be as follows:-
My invention relates to the rib portions of umbrellas, tents, carriage heads and
the like and consists, for the purpose of rendering the apparatus more portable or
otherwise convenient, in constructing such rib portions in such a manner that one
part of the flexible covering material of the apparatus may be capable of reflexing
and folding over against or parallel to the other portion or portions thereof.
According to my invention the ribs over which the flexible covering material is
stretched are each formed in more than one length one partly overlapping the
other. The said ribs are designed to fold at the overlap but they are not jointed
together at their extremities. The extremity of the overlapping rib is jointed
either directly to its neighbour or to a lug carried on it more or less distant from
the extremity of such neighbouring rib and such extremity of the neighbouring rib
is jointed to one of the "stretcher" ribs of the apparatus.
In applying my invention to an umbrella, for example, the ribs over which the
covering material is stretched may conveniently he formed each in two lengths.
The extremity of one length may be jointed to the stem or central support in the
usual or a convenient manner and the other extremity is jointed either directly to
its neighbour or to a lug carried on it more or less distant from its overlapped
extremity. To the extremity of the overlap of this said other rib the "stretcher
rib is jointed. The opposite end of the "stretcher" rib may be jointed to the
usual or a convenient collar adapted to slide on the stem or central support.
"
When the apparatus is folded, the two ribs and the "stretcher" rib will be
parallel to each other and the flexible covering material will be folded face to face.
To extend the covering, for example in an umbrella where a central support is
employed, the sliding collar is pulled down the stem or central support until the
joint between the stretcher rib and the other rib to which it is jointed becomes a
re-entering angle instead of a salient one. The sliding collar is thereupon raised
till the two lengths of rib assume the desired position for extending the covering.
The sliding collar may be secured in its position by a spring, fid, screw or other
device. The stem or central support may be telescopic, hinged, jointed or
the like.
In adapting my invention to a carriage head or the like where a central stem is
not employed the ribs over which the covering material is stretched may likewise
conveniently be formed each in two lengths. The extremity of one length of each.
rib may be jointed or pivotted to a main framework or support carried by the
vehicle and the other extremity may be jointed to its neighbour as herein before
described more or less distant from its overlapped extremity. The "stretcher
rib may be jointed at its one extremity to the overlap as described and at its other
extremity to a second framework or support carried either by the vehicle or by
the said main framework or support.

Carriage Heads, and the like.
I, EDWIN RUCK KESTERTON, of No. 14 Nightingale Lane, Balham, in the
County of London, Coach Builder, 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 the rib portions of umbrellas, tents, carriage heads and
the like and consists, for the purpose of rendering the apparatus more portable or.
otherwise convenient, in an improved method of constructing such rib portions in
such manner as hereinafter described that one part of the covering material of the
apparatus may be capable of reflexing and folding over against or parallel to the
other portion or portions thereof.
In the accompanying drawings
Figures 1 and 2 show the application of my invention to an umbrella or shade
with central support, Figure 1 showing the apparatus open and Figure 2 closed.
Figures 3, 4, 5 and 6 illustrate the various positions of the parts in the course of
being operated.
Figures 7, and 8 (Figure 7 being a perspective view and Eigure 8 a side view)
show the invention adapted for use as a head or shade to a vehicle,
Figures 9 and 10 show, front and end views respectively of a sunblind, and
Figures 11, 12, 13, 14 and 15 are detail views drawn to an enlarged scale and
hereinafter more particularly referred to.
According to my invention the ribs over which the covering material is extended
are each formed in more than one length one partly overlapping the other, as
shown at a. The drawings show such ribs in two lengths A, A stretching or
covered by the covering material B. The said ribs are designed to fold at the
overlap but as will be seen they are not jointed together at their extremities but
the extremity of the rib A is connected either directly to its neighbour A or, to a
lug carried on it, more or less distant from the extremity of such neighbouring
rib. At or near the extremity of this latter rib A' one of the "stretcher" ribs, C
of the apparatus is jointed.
Figures 1 and 2 show, my invention applied to au umbrella or other shade with
central support, the ribs A being jointed to the top-notch D which is fastened to
the support or stick E in the usual way. The stretcher ribs are jointed to the
ribs A as shown and their opposite ends are jointed in the usual way to the collar,
or runner, F adapted to slide upon the said support or, stick. If desired the support
The
or, stick may be telescopic, hinged jointed or otherwise adapted to fold.
drawing, shows this effected by, the joint G held in position by the collar H.
preferable that this collar, while maintaining the support rigid, should afford
clearance to the runner in its passage of the latter over the stick or support.
Accordingly the diameter of the support is decreased at this point sufficiently to
allow for the thickness of the said collar.
It is
When the rib portions of the apparatus are folded or closed as shown in Figure 3
each pair of ribs and their stretcher rib will be parallel with each other and the
covering material will be folded face to face. To extend the covering the sliding
collar or runner F is pulled down the stick E or equivalent support until the joint
between each stretcher rib Cand the corresponding rib A' to which it is jointed
becomes a re-entering angle as shown in Figure 5 instead of a salient one as shown

page_text: in Eigure 4. The runner F is thereupon raised till the lengths, of rib. A and. A
assume the desired position for extending and covering as in Figure 6. A spring J,
(see Figures 1 and 2) or equivalent device serves to retain the runner F in its
required position.
In adapting my invention to a carriage or vehicle head or otherwise where a
central support or stem is not employed the ribs A and A¹ as shown in Figures 7
and 8 over which the covering. material is extended may likewise conveniently
be formed in two lengths. The one extremity of each rib A may be jointed
or pivoted to a rod or support K instead of to a top-notch D as shown in the
previous figures and the other extremity is jointed to its neighbour as hereinbefore
described with reference to Figures 1 to 6. The stretcher ribs C may each be
jointed to the overlap as described and their opposite end to a second rod or
support L adapted to move to and from the rod or support K and taking the
place of the collar or runner F as shown in the previous figures. The rod or
support K is fixed to or slides upon one or more uprights M which in the
latter case are furnished with fids or catches to retain the rod or support K
in position. The rod or support L slides on the upright or uprights M and is
secured in position by a catch in the same manner as the runner F already
referred to. The uprights may be fixed movable or jointed similarly to the
support E shown in the previous figures. It will be obvious that a similar
arrangement might be applied to brakes, wagonettes and other similar vehicles
the framework running in the direction of the length of the vehicle instead of
in that of its width as shown in Figure 7.
When applied to a sunblind the stretcher ribs C may run upon guides N
as shown in Figures 9 and 10. A sunblind formed as described will close up
into a smaller space than those at present in use besides possessing other
advantages.
As shown more clearly and on an enlarged scale in Figures 11, 12 and 13
the rib A may be forked and jointed to the lug on the rib A¹ by the pin p.
In order to further strengthen the arrangement the stretcher rib C may terminate
in a hook h which engages in its motion with, and is limited by, the pin g
secured between the forks of the rib A. Or the movement of the rib A' may
be limited by the projection as shown in Figures 14 and 15. In these detail
views Figure 11 shows the arrangement open and Figure 13 closed while
Figure 12 is a cross-sectional view of Figure 11. Additional strength may be
secured by forming the ribs A as shown in plan and elevation respectively in
Figures 14 and 15 with two members a¹ and a splaying outwards and braced
together where necessary by struts a³.
Although herein described in general terms with modifications indicated
rendering it applicable to certain, useful purposes I do not limit my invention
to the precise details, uses and modifications set forth, it being obvious that
the same may be varied in numerous ways without departing from the spirit
of the invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what
claim is :-
1. In an umbrella, tent, carriage-head, sunblind or the like the rib A jointed at
its one extremity to a rigid support and at its other extremity either directly or
indirectly to another rib A' at a point removed from its extremity and a stretcher
rib jointed at or near this latter extremity and extending to a movable collar or
runner substantially as set forth.
2. In a carriage-head, sunblind shade or the like the combination of stationary
or movable supports with a fixed or dropping framework and a series of folding
and reflexing ribs substantially as described with reference to Figures 7, 8, 9
and 10 of the accompanying drawings.
3. In folding and reflexing ribs such as herein before referred to, the means for

page_text: limiting the motion of, for strengthening, and for locking such ribs substantially as
described with reference to Figures 9, 10, 11, 12, 13, 14 and 15 of the accompanying
drawings.
