JOHN EDMONDS, 23, Pershore Road, Edgbaston, in the Borough of Birmingham,
in the County of Warwick, Machinist, do hereby declare the nature of this invention
to be as follows:-
The blank is cut out of sheet or strip metal, but longer than usual, and the ends
which form the two ears for the joint are doubled over to the inside and forced
against the rib, when it is being fixed on the rib; though it need not be done.
I prefer, also, to close round the rib the four corners which project at the sides of
the blank, thereby making a firmer joint, and the ears are also made stronger by the
extra thickness of metal; the ends of the blank may be doubled over on the outside,
instead of inside, when they will force the inside metal on to the rib.
When applied to paragon ribs, the ends and the four corners, which project at the
sides of the blank, must be forced into the inside of the rib. After the middle bit is
fixed on the rib, the cars are pierced for the rivet, and the corners rounded off, or the
holes may be pierced in the blank, and the blank may be made with bits cut out of it
at the doubling parts, so that when it is doubled over the cars will have the corners
off. For ribs that are cranked, the middle bit may be pressed to the form of the
crank, so that it will fit on and stop it from moving on the rib, or a hole may be
pierced in the blank to fit the crank or for any other purpose. The ends of the blank
may be made a semi circle, or any other form, so that when it is doubled over on the
outside it will have the appearance of a washer.
For solid ribs that are not cranked, or those that have a long crank, the middle bit
may be made the same width at that part which goes round the rib as the parts which
form the ears.
Middle bits made as herein described may be used with one prong stretchers, or
with one prong stretchers having a sheet metal two-prong fork in addition, or with
two prong stretchers; the ears of the middle bit may be pressed close together, if
required to be used with two-prong stretchers.

page_text: Improvements in Middle Bits for Umbrella and Parasol Ribs.
I, JOHN EDMONDS, 23, Pershore Road, Edgbaston, in the Borough of Birmingham,
in the County of Warwick, Machinist, 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:-
This invention relates to improvements in middle bits for Umbrella and Parasol
ribs.
In order to enable the invention to be fully understood I will proceed to
describe the same by reference to the accompanying drawing.
The blank (figure 1) is cut out of sheet or strip metal, but longer than usual; the
ends (A, A, figure 1), which form part of the two ears for the joint, are doubled
over to the inside, and forced against the rib when it is being fixed on the rib
(see A, A, figure 2); though it need not be done, I prefer, also, to close round the
ril the four corners that project at the sides of the blank (see 13, B, B, B, figures 1
and 3, and B, B, figure 4), thereby making it firmer on the rib, and the ears are
also made stronger by the extra thickness of metal; the ends of the blank may be
doubled over on the outside, instead of inside, when they will force the inner metal
on to the rib (scc A, A, figure 5, and A figure 8). When applied to paragon ribs
the ends (A, A, figure 1) and the four corners (B, B, B, B, figure 1), that project at
the sides of the blank, must be forced into the inside of the rib (see A, A, figure 6).
After the middle bit is fixed on the rib, the ears are pierced-either in the centre or
out of the centre of the ears-for the rivet, and the corners rounded off (see
figures 7, 8, 10, 11, 12, 14, and 15), or the holes may be pierced in the blank-citler
in the centre or out of the centre of those parts which form the cars- -(see figure 9),
and the blank may be made with bits cut out of it at the doubling parts (see c, c, c, c,
figure 9), so that when it is doubled over the ears will have the corners off (sec
figures 7, 8, 10, 11, 12, 14, and 15). For ribs that are cranked, the middle bit may
be pressed to the form of the crank, so that it will fit on and stop it from moving
on the rib (see D figure 10), or a hole may be pierced in the blank to fit the crank
(seo D figures 1, 9, 11, and 12) or for any other purpose. The ends of the blank may
be made a semi circle, or any other form, so that when they are doubled over on the
outside they will have the appearance of washers (see A figure 12). For solid ribs
that are not cranked or those that have a long crank (see E figure 13), the middle bit
may be made the same width, or nearly the same width, at that part which goes round
the rib as the parts that form the cars (see F figures 14 and 15). Middle bits made
as herein described may be used with one prong stretchers (see figure 16), or with one
prong stretchers having a sheet metal two prong fork in addition (see figure 17), or
with two prong stretchers (see figure 18); the ears of the middle bit may be pressed
close together, if required to be used with two prong stretchers (see figure 19).

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, I declare that what I
claim is :
1. A middle bit for solid ribs having the ends of the blank, which form part of the
two cars for the joint doubled over to the inside and forced against the rib to hold it
thereon, and with or without the four corners that project at the sides of the blank
being closed round the rib, substantially as described.
2. A middle bit for solid ribs having the ends of the blank, which form part of the
two ears for the joint, made square, a semi circle, or any other form, and doubled over
on the outside to force the inner metal on to the rib to hold it thereon, and with or
without the four corners that project at the sides of the blank being closed round the
rib, substantially as described.
3. A middle bit for solid ribs having the ends of the blank, which form part of the
two ears for the joint, either doubled over to the inside and forced against the rib to
hold it thereon or doubled over on the outside to force the inner metal on to the rib
to hold it thereon, and with or without the four corners that project at the sides of the
blank being closed round the rib, and also having both ears closed together to be used
with a two prong stretcher, substantially as detcribed.

4. A middle bit for paragon ribs having the ends of the blank, which form part of
the two cars for the joint, and the four corners that project at the sides of the
blank, doubled over to the inside and forced inside the rib to hold it thereon, sub-
stantially as described.
5. A middle bit for solid ribs having that part of the blank which goes round the
rib the same width, or nearly the same width, as the parts that form the two cars,
and having the ends, which form part of the two ears for the joint, doubled over
to the inside and forced against the rib to hold it thereon, substantially as described.
6. A. middle bit for solid ribs having that part of the blank which goes round the
rib the same width, or nearly the same width, as the parts that form the two cars,
and having the ends, which form part of the two cars for the joint, made square, a
semi circle, or any other form, and doubled over on the outside to force the inner
metal on to the rib to hold it thereon, substantially as described.
7. A middle bit for solid ribs having that part of the blank which goes round the
rib the same width, or nearly the same width, as the parts that form the two ears, and
having the ends, which form part of the two ears for the joint, either doubled ovir
to the inside and forced against the rib to hold it thereon or doubled over on the
outside to force the inner metal on to the rib to hold it thereon, and also having
both cars closed together to be used with a two prong stretcher, substantially as
described.
