Improvements in and relating to Umbrella Furniture.
I, WALTER BERNARD CHALLEN, of the Firm of Taylor and Challen, Limited,
of Derwent Foundry, Constitution Hill, in the City of Birmingham, Engineers,
do hereby declare the nature of this invention to be as follows:
My invention has for its object the manufacture in a ready and convenient
manner from sheet metal of strong and durable sockets or runners for umbrellas.
I produce umbrella runners in accordance with my invention from solid drawn
metallic cases having one end closed. Each of such cases I place upon a die
or forming tool with the closed end uppermost or outermost. The body of the
die or forming tool is of such an external diameter as to fit freely within the metal
case, whilst a central hole or aperture is formed through the tool corresponding
with the required external diameter of the body or barrel portion of the runner.
By means of a suitable punch working within the central aperture of the die
or forming tool a portion of the case is reversed or turned inside out, leaving a
sufficient length at the open end unaffected, for the subsequent formation of the
notched head or flange of the runner.
The notched head or flange is formed by subjecting the aforesaid unaffected
portion of the case to the compressive action of suitable tools, but prior to such
operation I sometimes insert a strengthening ring in the annular space formed
between the reduced body or barrel part of the runner and the portion left for
the formation of the head, such ring serving also to preserve or maintain the
required internal diameter of the groove hereinafter referred to.
By such a method of pressing up the head or flange the necessary central
peripheral groove is formed in the runner, which only requires to be opened
out in any ordinary manner; but I sometimes employ a pair of half dies or a
circular distance piece or washer to preserve the shape of the groove.
The notches are cut through the head or flange in any convenient manner,
and after the closed end of the body or barrel part of the runner has been
removed the extremity is turned over to form the usual bead.

page_text: 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 has for its object the manufacture in a ready and convenient
manner from sheet metal of strong and durable sockets or runners for umbrellas.
In the two accompanying sheets of explanatory drawings to be hereinafter
referred to.
Figures 1 to 7 inclusive on Sheet 1 illustrate various stages in the manufacture
of my improved umbrella runners, whilst Figures 8 to 12 on Sheet 2 represent
some of the tools employed in the said manufacture.
I produce umbrella runners in accordance with my invention from solid drawn
metallic cases having one end closed. Each of such cases, one of which is shown
in sectional elevation at Figure 1, I place upon a die or forming tool such as A
Figure 8, with the closed end uppermost or outermost. The body of the die
or forming tool is of such an external diameter as to fit freely within the metal
case, whilst a central hole or aperture is formed through the tool corresponding
with the required external diameter of the body or barrel portion of the runner.
By means of a suitable punch, as B Figure 8, working within the central
aperture of the die or forming tool a portion of the case is reversed or turned
inside out, leaving a sufficient length at the open end unaffected, for the subse-
quent formation of the notched head or flange of the runner. The punch B
is shown at the end of its in-stroke at Figure 8, and a separate sectional elevation
of the case after its subjection to the aforesaid reversing operation is shown at
Figure 2.
The notched head or flange is formed by subjecting the unaffected portion a
(Figure 2) of the case to the compressive action of suitable tools, but prior to
such operation I preferably insert a strengthening ring in the annular space
formed between the reduced body or barrel part of the runner and the portion
left for the formation of the head, such ring serving also to preserve or maintain
the required internal diameter of the groove hereinafter referred to. Figure 3
is a sectional elevation of the case after the attachment of the strengthening ring b
therein; the outer edge of the ring is made to a concave form and it is secured
in the required position in the case by forcing or compressing the latter upon
such concave edge as shown in the section at Figure 3, the operation being
effected preferably by a revolving disc in a lathe or other machine.
For the first compressive operation for the formation of the head and neck
to the extent shown at Figure 4, I employ a closing punch C and a closing die D
such as shown at Figure 9; the head is further compressed by the action of a
suitable punch and die and is finally closed to the form shown in the section
at Figure 5 preferably by the action of a punch as E, die F, and hinged collar
or distance piece G, shown at Figure 10. The hinged collar or distance piece G
is provided with an internal circular rib or projection corresponding with the
required dimensions of the central peripheral groove a¹ in the runner head, and
the two parts of the collar are provided with a detachable connection as the nut
or binder G which fits on to the free ends of the collar as shown in the plan
view at Figure 12.
The notches are cut through the head or flange in any convenient manner,
and after the closed end of the body or barrel part of the runner has been removed
the extremity is turned over to form the usual bead, as shown at Figure 6, by
a punch Hand die J such as shown at Figure 11, a hinged collar as K, of a
similar type to the collar G hereinbefore described, being employed in combina-
tion with such tools. The turning over of the metal to form the bead is com-
pleted by spinning in a lathe in the ordinary manner.
The completed runner with its head or flange notched and the bead at the
opposite end flattened or compressed, is shown at Figure 7.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. Sockets or runners for umbrellas formed from solid drawn metallic cases,
substantially as described.
.
2. In the manufacture of sockets or runners for umbrellas from metallic cases,
reversing or turning a portion of the said cases inside out, substantially as and
for the purposes described.
3. In the manufacture of sockets or runners for umbrellas from metallic cases,
the use of a ring as b in combination with the head or flange formed on one end
of the case, substantially as and for the purposes described and as illustrated.
4. The manufacture of sockets or runners for umbrellas from solid drawn
metallic cases, substantially in the manner described and as illustrated.
