PROVISIONAL SPECIFICATION.
Improvements in Frames for Umbrellas and the like.
I, JOHN WEEKS, of 89, Hill Street, Peckham, in the County of Surrey, Umbrella
Maker, do hereby declare the nature of this Invention, to be as follows:-
At the stretcher-joint of a U shaped rib I turn over towards the inside and flatten
down the sides of the rib and form the git with two correspondingly shaped lugs
containing the holes for the joint pin or rivet, so that when the git is lapped round
the rib at this place, the lugs of the git fill the hollow formed in each side of the rib
by the aforesaid turning over and flattening down of the sides of the same. If the
rib is bulged and the git perforated at this place as described in the specification of
my patent No. 5565 of 1887, then the joint is well down in the hollow of the rib
without loss of strength to the joint, the rivet not passing through the rib but through
the git, and the stretcher and the rib fold closely into each other without protruberance
at the joint. In connection with the rib and git, formed as described, I may use any
stretcher with three-pronged-rib-joint-end but by preferenco the three-pronged-
stretcher claimed in my aforesaid patent specification, or a stretcher made of double
U shaped section with a two-pronged-fork-end made all in one piece, the end of the
stretcher being split along the centre, and the two lugs thus formed being each
pressed down against the respective side lug of the stretcher. This form of stretcher
is by preference made out of ribbon metal folded into the required double U section
by rolling but may also be made otherwise such as by rolling out of the solid.

COMPLETE SPECIFICATION.
Improvements in Frames for Umbrellas and the like.
1, JOHN WEEKS of 89 Hill Street Peckham in the County of Surrey Umbrella
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:-
These improvements refer to the ribs and stretchers and especially to the rib and
stretcher joint of an umbrella frame and combine to make the frame more compact
when folded while at the same time the strength and lightness are increased.
In the accompanying drawings figure 1 is a side view of the improved form of rib
at the stretcher joint and figure 2 a cross section. Figure 3 shews the git before
being bent and figure 4 after being bent into shape ready to be applied; figure 5 is a
cross section of the git. Figure 6 is a side view and figure 7 a cross section through
the stretcher joint after the git has been applied and bent over. and the rivet. holes
made therein. Figure 8 is a plan view of the stretcher, which as will be seen has a
three pronged joint end.
Figure 9 is a side view and figure 10 a cross section of the rib and stretcher joint
and figure 11 a cross section through the rib and stretcher folded. Figure 12 is a
side view in continuation, though broken in length, of figure 9 of rib and stretcher at
the place where the rib enters a notch in the runner flange and figure 13 is a cross
section through the rib at this place.
•

page_text: Figure 14 is a side view of a rib and stretcher joint where the stretcher has a two
pronged end, and figure 15 a plan; the prongs being outside of the rib the latter
folding into the stretcher..
Figure 16 is a side view and figure 17, a plan of a rib and stretcher joint where the
two stretcher prongs are inside of the rib but the rib otherwise lying inside the
stretcher.
At the stretcher, joint of a U shaped rib A figures 1 to 13. I turn, over towards the
inside and flatten down the sides. of the rib as shewn at A figures 1 and 2 and I form
the git B figure 3 with two correspondingly shaped lugs B₁ for containing the holes
for the joint pin or rivet so that when the git is first hent into the shape shewn in
figures 4 and 5 and lapped round the rib at this place and the lugs B' folded inwards
as shewn in figures 6 and 7, the lugs B¹ of the git fill the hollow formed in each side
of the rib by the aforesaid turning over and flattening down of the sides of same.
The git is thus prevented from shifting endways along the rib.
If the rib as here shewn at A2 figure 1 is bulged and the git perforated at this
place as shewn at B' figures 3. 4. 5. 6. 9. and 10 and as described in the specification of
my patent No. 5565 of 1887, then the joint is well down in the hollow of the rib
without loss of strength to the joint, the rivet C not passing through the rib A but
through the two side lugs B' of the git, and the stretcher and the rib fold closely into.
each other without protuberance at the joint, as shewn at figures 9. 10 and 11.
In connection with the rib and git formed as described I may use any stretcher
with three-pronged rib joint end but by preference the three pronged stretcher
claimed in my aforesaid patent specification. This form of stretcher (or a two pronged
stretcher presently to be described) is by preference made of ribbon metal folded into
the required double U section by rolling but may also be made otherwise such as by
rolling out of the solid. In figure 8. 9. 10. and 11 is shewn a threepronged stretcher
made out of one piece of ribbon metal by rolling. The rib where it lies in the notch.
formed in the edge of the runner flange is as shewn at E figures 12 and 13 flattened
down so that, the ribs will lie deeper in the said notches and the umbrella when folded
will present a less bulky appearance at this place.
In figures 14 and 15. I have shewn my invention applied to a joint with a two-
pronged stretcher of doubie U section made all in one piece. The fork is at Di
crushed in so as to allow the sides of the rib with git to fold with it.
Figures 16 and 17 shew.a two-pronged stretcher of double U section made all in
one piece and out of a piece of ribbon metal by rolling. The fork is at. D² crushed in
so as to allow the sides of the rib and git to fold with it.
Having now particularly described and ascertained the nature of this Inven-
tion and in what manner the same is to be performed I declare that what I
claim is ;-
.
1. A trough or U shaped umbrella rib having parts of the sides at the stretcher
joint.turned over towards the inside and flattened down substantially as set forth.
2. A trough shaped umbrella -rib formed with a bulge A at the stretcher joint and
having turned down parts A' at that place substantially as set forth.
3. In combination with a trough shaped umbrella rib having turned down stretcher.
joint parts A' a git B with lugs B which are turned down towards the inside to fill
the cavities at A' and are adapted to receive the rivet C which passes through the git
but not through the rib substantially as set forth.
4. The git Bwith lugs B B and hole B in combination with a trough shaped
rib A with turned down parts A¹ and bulge A' substantially as set forth.
5. In a trough shaped umbrella rib the flattened down part E for the purpose of
bringing the rib closer to the runner substantially as set forthi.
6. A trough shaped umbrella rib having turned over parts E.and A and a git B
with turned down lugs B and rivet (in combination with a double U shaped
stretcher D substantially as set forth.

page_text: 7. An umbrella stretcher having a two pronged fork for connecting the stretcher
to the rib fashioned out of one piece of double U shaped metal substantially as set
forth.
