PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Umbrella and Parasol Ribs.
We, WILLIAM ALLEN BINDLEY and WILLIAM JAMES GELL, both of Armstrong
Works, Chester Street, Aston Road, Birmingham, in the County of Warwick,
Manufacturers, and JOSEPH FREDERICK BOILAM, of No. 129, Frederick Road,
Aston, near Birmingham, aforesaid, Machinist, do .hereby declare the nature of
this invention to be as follows:-
Our invention consists of the improvements hereinafter described in the manu-
facture of the combined tip and tip plates hereinafter called the tips of the
umbrella and parasol ribs and the attachment of the said tips to umbrella and
parasol ribs as well as to the formation of the eyes at tip ends of the ribs.
In manufacturing a tip according to our invention we make by a stamping or
piercing operation from a strip of thin sheet metal preferably brass, a blank,
somewhat resembling a spherical pointed slip pen blank, that is to say the said
blank consists of a tapering end part with an enlargement at its smaller end; the
larger end of the tapering part passing into the other end part, which has parallel
sides, by a contraction or neck and we take a star like disc from which to make the
spherical end or tap proper. By a troughing and bending operation we give to
the end part with parallel sides, a U shape in cross section and the other or taper-
ing end part we form into a tapering tube the enlarged point end serving to hold
the spherical tip proper which is fitted thereto and closed thereon in the ordinary
way. The contraction or neck in the blank herein before described constitutes
a V shaped depression between the tapering tubular end and the U shaped
trough for the purpose hereinafter described.
We make in the solid umbrella or parasol rib and near the end thereof a nearly
semi-circular bend and we place the tip made in the manner hereinbefore
described on the end of the said rib so that the semi-circular bend in the end of
the same coincides with but is opposed to the V shaped depression in the tip,
that is to say, the open side of the semi-circular bend in the rib is presented to
the bottom of the trough of the tip. There is thereby formed at or about the
middle of the tipped end of the rib an eye. The parallel sides of the U shaped
trough of the tip are next closed on the rib so as to firmly secure the tib to the
rib. The eye at the tipped end of the rib is thus made partly from the rib itself
and partly from the sheet metal tip.

In manufacturing a tip according to our invention we make by a stamping or
piercing operation from a strip of thin sheet metal preferably brass, a blank,
somewhat resembling a spherical pointed slip pen blank, that is to say, the said
blank consists of a tapering end part with an enlargement at its smaller end, the
larger end of the tapering part passing into the other end part, which has parallel
sides, by a contraction or neck and we take a star like disc from which to make the
spherical end or tip proper. By a troughing and bending operation we give to
the end part with parallel sides, a U shape in cross section and the other or taper-
ing end part we form into a tapering tube the enlarged point end serving to hold
the spherical tip proper which is fitted thereto and closed thereon in the ordinary
The contraction or neck in the blank herein before described constitutes
a V shaped depression between the tapering tubular end and the U shaped
trough for the purpose hereinafter described.
way.
We make in the solid umbrella or parasol rib and near the end thereof a nearly
semi-circular bend and we place the tip made in the manner hereinbefore
described on the end of the said rib so that the semi-circular bend in the end of
the same coincides with but is opposed to the V shaped depression in the tip,
that is to say, the open side of the semi-circular bend in the rib is presented to
the bottom of the trough of the tip. There is thereby formed at or about the
middle of the tipped end of the rib an eye. The parallel sides of the U shaped
trough of the tip are next closed on the rib so as to firmly secure the tip to the
rib. The eye at the tipped end of the rib is thus made partly from the rib itself
and partly from the sheet metal tip.
Figures 1 and 2 of the accompanying drawing represent in plan and edge view
the slip pen like blank and star shaped blank respectively from which the com-
bined tip plate and tip are made.
Figures 3 to 10 both inclusive are views of the tip plate in the various stages
of its manufacture, and
Figures 11, 12 and 13 are views of the partly made tip after the cupping
operation of the star shaped blank Figure 2.
Figures 14, 15 and 16 illustrate the application and fixing of the tip to the
tip plate and Figures 17, 18 and 19 illustrate the application and fixing of the
combined tip and tip plate to the umbrella rib and the formation of the eye at
the tip end of the rib.
All the figures of the drawing are drawn to a large scale.
The same letters of reference indicate the same parts in the several figures of
the drawing.
In manufacturing tip plates according to our invention we make by a stamping
and piercing operation from thin sheet nietal, slip pen like blanks of the kind
represented in plan and edge view in Figure 1 and by a pressing operation we
trough the said blanks in the manner represented in plan and elevation in
Figures 3 and 4 respectively and in cross section in Figures 5, 6 and 7 the said
sections being taken respectively on the lines 2, ; y, y and z, z Figure 4. By
a bending or closing operation we give to the tapering end of the tip plate the
form of a conical tube (see Figures 8, 9 and 10) with a projection a at its smaller
end to receive the tip.
.
In manufacturing the tip we convert the star shaped blank Figure 2 by a
pressing operation into the serrated or undulating edged bowl or cup represented
in plan in Figure 11, elevation in Figure 12 and.section in Figure 13.

page_text: The said partly made tip Figures 11, 12 and 13 is attached to the lip plate by
passing it on to the projection a at the end of the tip plate and by closing the
series of arms of the said partly made tip on the projection a of the tip plate as
will be understood by reference to the elevation Figure 14, section Figure 15
and plan Figure 16.
In order to form the eye at the tip end of the rib we make a bend or notch b
near the extreme end of the rib (see Figure 17) and pass the extreme end of the
said rib into the conical tubular end of the tip plate with the bend or notch b in
the said rib opposed to the depression of the trough of the tip plate (as seen in
Figure 18). The depression in the sides of the tip plate is formed by the neck
near the middle of the blank Figure 1. The said tip plate is secured to the rib
by the bending or closing of the edges of the U shaped trough of the tip plate
(see Figure 5) on the rib above the bend or notch b in the said rib as will be best
understood by reference to the elevation Figure 18 and section Figure 19. It
will thus be seen that the eye at the tip end of the rib, through which eye the
sewing of the umbrella cover to the rib is effected, is formed partly from the rib
itself and partly from the tip plate attached to the rib.
Although we have only represented our invention applied to a solid rib to which
it is particularly applicable yet our invention may also be used in connection, with
hollow or trough ribs.
Having now particularly described and ascertained the nature of our inven
tion. and in what manner the same is to be performed we declare that we claim
as our invention of "Improvements in the Manufacture of Umbrella and Parasol
Ribs"-
Making the eye at the tip end of the rib partly from the rib itself and partly
from the tip plate attached to the rib by forming a bend or notch near the end
of the solid or other rib and a depression in the tip plate of the combined tip
and tip plate and so applying and closing the tip plate upon the solid or other
rib that the depression in the said tip plate is opposed to the band or notch in
the rib so as to form between them the eye of the tip substantially as hereinbefore
described and illustrated in the accompanying drawing.
