PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Paragon Umbrella Ribs and
Stretchers, and Machinery or Apparatus therefor..
I, WILLIAM CORDER, of the firm of Corder & Turley, of Allison Street Works,
in the City of Birmingham, Umbrella Frame Manufacturers, do hereby declare the
nature of this invention to be as follows:-
1
This invention relates to improvements on former Letters Patent No. 10,338 of
1886, the present improvements consisting in combining with the apparatus described
in the specification of the said former patent, of apparatus for forming the flat
metal into the required paragon or U shape wire for the ribs and stretchers.
For this purpose I provide a pair of shaping rolls between which the flat metal
is fed and by which rolls the said flat metal is formed into somewhat of a trough
shape; it is then fed through a pair of dies which bring the trough shape metal
into the required U or paragon shape.
In the specification of the said former patent the feeder was described as being
placed between the perforating or piercing punches and the nicking or cropping
punch, but I now place the feeder between the shaping dies and the flattening
block, the feeder being so constructed as to pull the wire through the said rollers
and dies and to feed it into the apparatus forming the subject of the said former
Patent No. 10338 of 1886. Suitable means are provided for straightening the
wire either as it leaves the shaping dies or after it has passed over the feeder.
By thus manufacturing paragon ribs and stretchers direct from the flat metal I
effect a considerable economy.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Paragon Umbrella Ribs and
Stretchers, and Machinery or Apparatus therefor.
I, WILLIAM CORDER, of the firm of Corder & Turley, of Allison Street Works,
in the city of Birmingham, Umbrella Frame Manufacturers, 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 on former Letters Patent No. 10338 of
1886, the present improvements consisting in combining with the apparatus described
in the Specification of the said former patent, of apparatus for forming the flat metal
into the required paragon or U shape wire for the ribs and stretchers.
For this purpose I provide a pair of shaping rolls between which the flat metal
is fed and by which rolls the said flat metal is formed into somewhat of a trough
shape; it is then fed through a pair of dies which bring the trough-shaped metal
into the required U or paragon shape.
In the specification of the said former patent the feeder was described as being
placed between the perforating or piercing punches and the nicking or cropping
punch, but I now place the feeder between the shaping dies and the flattening
block, the feeder pulling the wire through the said rollers and dies and feeding it
into the apparatus forming the subject of the said former Patent No. 10338 of 1886.
Suitable means are provided for straightening the wire either as it leaves the
shaping dies or after it has passed over the feeder.

page_text: By thus manufacturing paragon ribs and stretchers direct from the flat metal I
effect a considerable economy.
In order to enable my invention to be fully understood I will describe how it can
be carried into practice by reference to the accompanying drawings, in which
Figure 1 is a side view, and
Figures 2 and 3 are end views of the apparatus for forming the flat metal into
the required Ụ or paragon shape and which I employ in combination with the
apparatus forming the subject of the said prior Patent No. 10338 of 1886.
a, a¹ are the shaping rolls mounted in a suitable frame b and c, c¹ are the shaping
dies.
The flat metal (of the section shown in the enlarged view Figure 4) from which
the ribs or stretchers are to be made is fed to the shaping rolls a, a' by which it is
formed into a trough shape somewhat of the section represented in the enlarged view
at Figure 5 and in side elevation at e Figure 1. The metal, thus partly shaped, is
fed through the shaping dies c, c¹ by which it is formed into the required Paragon
or shape represented in section at Figure 6 and in side elevation at f, Figure 1.
The wire thus fashioned is then carried by the feeder to the flattening block of the
apparatus of the said former Patent No. 10338 of 1886, the said wire being
straightened either as it leaves the shaping dies or after it has passed over the feeder.
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 :-
The manufacture of paragon umbrella ribs and stretchers direct from flat metal
by the use of apparatus combined, arranged and operating substantially as herein-
before described and illustrated in the accompanying drawings.
Dated the 4th day of September 1889.
