COMPLETE SPECIFICATION.
An Improved Tubular Metal Stick for Umbrellas and Sunshades.
We, CHARLES WOOD, of Halewood Villa, Blenheim Road, Moseley,
Birmingham, Metal Merchant and Manufacturer, and ALFRED ERNEST BUSBY,
of 142 Bristol Road, Birmingham, aforesaid, Manufacturer, 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 consists of the herein described improved tubular metal stick for
umbrellas and sunshades our said improved stick being designed more particularly
for use with runners of the kind described in the Specification in connection with
our application for Letters Patent No. 20634 of A.D. 1894 but the said stick is
also applicable for runners of some other kinds and particularly where the runner
is made with a spring catch to engage with the stick.
We will describe our invention by referring to the accompanying drawing on
which
Fig. 1 shews a tubular metal umbrella stick constructed according to this
invention; Fig. 2 is a front view of two portions of the same on an enlarged scale;
Fig. 3 is a sectional plan of the same;
Fig. 4 is a side view of the two parts Fig. 2 partly in section;
Fig. 5 is a sectional view of the upper part of the said umbrella stick with one
of our said improved runners threaded on it;
Fig. 6 shews a part of our improved stick made with a wire catch for the
runner;
Fig. 7 shews in sectional elevation and in front elevation a portion of our
improved stick with the catch formed in another manner.
The same letters of reference indicate the same parts in all the figures of the
drawing.
Our said improved umbrella stick A consists of a thin metal tube drawn or
otherwise formed to an almost circular cross section but with a deep longitudinal
groove a extending all along or partly along the stick and reaching almost to
the centre of the tube so that the tube will have in section about the shape
represented by Fig. 3; or the groove may reach to the centre of the tube beyond
the centre. One object of this groove is to admit the catch piece 6 of the runner B
and allow the same sliding along the stick from its lowest to its highest position and
rice versa; or to contain a spring catch when an ordinary runner is used; a further
object of this said groove being to strengthen the stick which it does very
considerably. In the groove a¹ at those parts corresponding with the positions of
the runner B when the umbrella is open or closed we form two inclines marked
respectively C C² each inclined on one side c¹ and straight on the other side c² so
that the inclined part c¹ will act upon the catch of the runner B and force the
same outwardly and the straight part c² will act as a tooth to retain the spring
catch when the runner is in its extreme highest or lowest position. These
inclines C C are by preference made in the form of separate metal blocks fixed
in the groove a by being soldered therein, see Figs. 2, 4 and 5, or other con-
venient means may be employed for fixing or forming the inclines C₁ C in the
groove al as for instance the inclines may be stamped out of the groove a¹ as shewn
in Fig. 7.
The groove a¹ may either extend all along the stick from end to
end, or only partly along the same as far as the highest position of the runner
thereon.

page_text: Instead of employing a fixed inclined catch such as C' C2 in the groove a¹ as
above described and shewn in Figs. 1, 2 4, 5 and 7 to engage with the spring
catch on the runner we may as shewn in Fig. 6 fix a spring catch D in the
groove a corresponding with the highest and lowest positions of the runner so
as to engage with the same. This spring catch D is fixed at one end d¹ in the
groove and the other end of the catch passes through and works easily in a
hole in the bottom of the groove. This arrangement applies more particularly
when our improved stick is used with runners of the ordinary kind.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1. The hereindescribed improved tubular metal stick for umbrellas and sunshades
consisting of the almost circular metal tube A formed with the longitudinal
groove a¹ for the spring catch of the runner to travel along, the said groove
having the two inclines C1 C2 fixed or formed in it for the spring catch of the
runner to engage with when the umbrella is closed or fully open, substantially
as hereinbefore described and illustrated by Figs. 1, 2, 3, 4, 5 and 7 of the
accompanying drawing.
2. The hereindescribed improved tubular metal stick for umbrellas and sunshades
consisting of the almost circular metal tube A formed with a longitudinal groove a¹
for the spring catch of the runner to travel along substantially as hereinbefore set
forth.
3. The hereindescribed improved tubular metal stick for umbrellas and sunshades
consisting of the almost circular metal tube A formed with a longitudinal groove a¹
and provided with spring catches in said groove to maintain the runner in its
highest or lowest positions, substantially as hereinbefore described and illustrated
by Fig. 6 of the accompanying drawing.
