Improvements in Frames for Umbrellas and the like.
OWEN MEREDITH 46 Laird Street Birkenhead in the County of Chester
Foreman Boiler Maker do hereby declare the nature of this invention to be as
follows:-
These improvements consist in making the rib and stretcher section of the shape
of two rings or kidney shape formed out of one piece.
I also form a three lug prong rib stretcher joint at the stretcher joint of a two
rings or kidney shaped rib." I form the middle lug prong with a slot hole in it and
press it into the rib between the rings of the rib where it will strengthen the said
rib. I also form a git with both the ends turned over and flattened down partly
to form the two side lug prongs when the git is lapped round the rib, the other
parts of the aforesaid two side lug prongs are pressed one into each ring of the rib
at the same time the inner sides of the rings of the rib go into the aforesaid slot
hole of the middle lug prong to keep it in its place. The aforesaid pressed parts
of the said rib enable the centre of the rivet holes of the rib stretcher-joint to be
nearer the rib, so that the rivet passing through the aforesaid rivet holes and
stretcher-rib-joint-end will enable the rib and stretcher to come close to each other
when the umbrella is folded. The end of the rib that joins the top-notches is
flattened down to form one prong, the other end of the rib to be made in the
usual way.
The two rings or kidney shaped stretcher runner-joint-end is flattened down to
form one prong, the stretcher rib-joint-end being split along the centre and the two
prongs thus formed being each pressed closer to the sides of the stretcher. In
connection with the rib and with the git side lug prongs, and the middle lug prong
formed as described, I may use the U shaped stretcher with two-pronged-rib-joint-
end but by preference the two pronged stretcher made of the aforesaid section of
the shape of two rings or kidney shape. The roundness of the ribs and stretchers
thereby avoids the abrasion of the umbrella cover and stick when the umbrella is
closing or closed.
The rib having three prongs at the stretcher-joint the rivet will be fixed, the
stretcher being the moving part, at the stretcher rib-joint-end having only two
prongs it hinges on the aforesaid fixed rivet thereby moving freer and easier.
The umbrella frame by these improvements will be made lighter and also
increased in strength, and when folded will be made more compact.
The rib and stretcher are by preference made out of ribbon metal folded into the
required two rings or kidney shaped section of one piece, by rolling or drawn
through a die or otherwise made.

COMPLETE SPECIFICATION.
Improvements in Frames for Umbrellas and the like.
I, OWEN MEREDITH, of 46, Laird Street, Birkenhead, in the County of
Cheshire, Foreman Boiler Maker, 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 construction of umbrella and the like frames, and
consists in making the ribs and stretchers of hollow sections of great strength,
formed out of one piece, or separate pieces suitably combined.

page_text: I also form a three lug prong rib stretcher joint as hereinafter described by means
of which the stretcher can be suitably connected to the rib.
The object of my invention is to so construct the umbrella frames that they will
be both lighter and also of greater strength than those hitherto in use and when
folded will be made more compact. The roundness of the ribs and stretcher will
also avoid the abrasion of the umbrella and stick when the umbrella is closing or
closed.
And in order that my invention may be clearly understood and readily carried
into effect, I will now proceed to describe the same with reference to the annexed
sheet of drawings in which the same letters of reference indicate corresponding
parts in all the figures.
Figures 1 to 17 show various modifications in section and detail of the improve-
ments which constitute my invention.
C
In these figures a represents the rib, the stretcher, and c the git or joint piece.
The sections employed are illustrated in Figures 4, 7, 9, 11, 13, 15 and 16 of
which the sections shown in Figures 15, 16 and 17 are those which are most likely
to be used for the purposes of my invention.
In Figures 1, 2, 3 and 4, an arrangement is shown in which the rib a and
stretcher are made of two rings or kidney shaped sections formed out of one piece.
The stretcher is jointed by a rivet to the git c which consists of a piece of sheet
metal of the form shown in the flat in Figure 5; this git c is then lapped or folded
round the rib a saddlewise as shown in section in Figure 4. I form a middle lug
prong d with a slot hole d¹ in it as shown in Figure 6, and press it into the rib a
between the rings of the rib, where it will strengthen the said rib. I also form the
git c with both the ends turned over and flattened down partly to form the two side
Jug prongs when the git is lapped round the rib, the other parts of the aforesaid
two side lug prongs are pressed one into each ring of the rib a, at the same time
the inner sides of the rings of the rib go into the aforesaid slot hole d¹ of the
middle lug prong d to keep it in its place. The aforesaid pressed parts of the said
rib enable the centre of the rivet holes of the rib stretcher joint to be nearer the
rib so that the rivet passing through the aforesaid rivet holes and stretcher rib
joint end will enable the rib and stretcher to come close to each other when the
umbrella is folded. The end of the rib that is jointed to the top notches is flattened
down to form one prong, the other end of the rib is made in the usual way.
The two rings or kidney shaped stretcher runner joint end is flattened down to
form one prong, the stretcher rib joint end being split along the centre and the two
prongs thus formed being each pressed closer to the sides of the stretcher. The rib
has three prongs at the stretcher joint into which the rivet is fixed, the stretcher
being the moving part at the stretcher rib joint end and having only two prongs
which hinge on the aforesaid fixed rivet thereby moving more freely and easily.
Figures 7 and 8 show an arrangement similar to but more complicated than
Figures 1, 2, 3 and 4, in which the rib a and stretcher bare composed of a com-
bination of the two rings or kidney shaped sections.
.
In Figures 9 and 10, an arrangement is shown in which the stretcher 6 is made of
a double pear shaped section and the rib a of a kidney shaped section; in this case
the rib and stretcher fit into one another as shown so that the frame is very compact
when closed.
Figures 11 and 12 illustrate another arrangement in which the stretcher bis
composed of a channel shaped section; in this case the frame is also very compact
when closed.
In Figures 13 and 14, the rib a is made of a double pear shaped section and the
stretcher of a kidney shaped section; again in this case the frame is very compact
when closed.
The umbrella frames by these improvements are lighter and of greater strength
than those in ordinary use and can be more compact by being folded together.
The rib and stretcher are by preference made out of ribbon metal folded into
the required sections by being rolled or drawn through a die or otherwise made.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, declare that what I
claim is:
In the construction of umbrella frames and the like, the use of hollowed sectional
ribs and stretchers of the patterns illustrated in the annexed drawings or their
equivalents, all combined and operating together as ribs and stretchers, substantially
as described and illustrated in the various figures of the accompanying drawings.
