Improvements in Collapsible Umbrellas.
We, ANTON KRIEGHOFF, of Buffalo, New York, No. 1019 West Avenue,
Travelling Salesman, ROBERT CHILD HICKOK, of 321 West Utica Street,
Buffalo, New York, Manufacturer of Steam Engines and Machinery, and GEORGE
PURDY ARMSTRONG, of 1019 West Avenue, Buffalo, all in the United States of
America, 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 :—
Our invention relates to a new and improved umbrella, which may be collapsed
or telescoped together or reduced in size, so that it can be put away in a small
trunk or satchel or opened out and expanded into an umbrella of the usual size
when required for use, all of which will be fully and clearly hereinafter described.
In the accompanying drawing,
Figure 1 is a side elevation showing the extensible stick and two of the braces,
also a central section through the runner to which the lower ends of the braces
are pivoted and a longitudinal central section through two of the hollow parts of
the ribs in which the inner sections of the ribs slido, all other parts being omitted.
Figure 2 is a longitudinal section through one of the outer or hollow sections of
the ribs, showing the inner section of the rib within it and its brace pivoted
thereto.
Figure 3 is an enlarged longitudinal central section through a portion of the
telescopic stick in or about the lines a a, Figure 6, showing a side elevation of the
spring for holding the two parts of the stick in position when opened out, the apring
being represented as pushed in the proper position when it is desired to release
them so that one part may be pushed into the other.
Figure 4 is a side -elevation of an umbrella drawn to the same scale as that
shown in Figure 1 and put together or reduced in size so that it can be packed in a
satchel or small trunk.
Figure 5 is an enlarged longitudinal central section through a portion of the two
parts of the telescopic stick and also through the runner to which the lower ends
of the braces are pivoted, showing the spring in position for holding the two parts
of the stick in position when opened out, also the spring for holding the runner up
when the umbrella is opened out for use.
Figure 6 is a horizontal section through the telescopic stick on the lino e c,
Figure 3.
Figure 7 is an enlarged cross section through one of the outer hollow portions,
and ribs, in or about line ee Figure 2, cutting also through the outer and inner rib
and showing a portion of the brace pivoted to it.
The telescopic stick is constructed in two tubular parts 1 and 2, one adapted to
slide within the other. One part is provided with a longitudinal groove, 3 see
Figures 3 and 6, the other part is provided with a pin or projection, which fits in
Baid groove see Figure 6. The object of this construction is to prevent part 1
from turning in the part 2, while it is allowed to be moved freely in or out.
The two parts 1 and 2, of the stick are kept rigidly in position when extended
to the limit of their outward movement by means of a spring 5, riveted to tho
inner side of the handle, 1, by a rivet 5ª, (see Figures 3 and 5) which springs into
a slot in the portion 2, for holding the two parts firmly as shown in Figure 5.
When it is desired to telescope the two parts of the stick, it is done as shown in
Figure 3, the portion, 1 is curved out substantially as shown at 6, (in said Figure 3)

page_text: cutting nearly through the handle lengthwise of the slot 7, the curved depression, 6,
in the portion, 1, of the stick passes through it or nearly so.
From the above construction it will be seen that the spring 5, can be easily forced
inward as shown in said Figure 3, and the part, 1 of the stick can be freely moved
down into the part, 2.
any
The stick may be made of brass, or steel which is preferable, or of suitable
material, it is provided with an ordinary handle, 10, of any suitable form.
The runner, 11, is made in the usual form, and large enough to slip easily over
the large portion, 2, of the stick and is provided with a series of inwardly projecting
springs, 12, which press against the smaller portion, 1, of the stick and thereby
keep it in a central position around it and at the same time spring in enough to
allow the runner to be easily forced over the inclined end, 13, of the stick portion, 3,
and then back or forth along the same.
When the umbrella in opened out as in Figure 1, the runner and umbrella is
kept up by means of a spring, 14, secured by a rivet 15, to the inner side of the
smaller portion, 1, see Figure 5. This spring, 14, projects through a slot, 16, in
said stick under the runner as shown in said Figure 5. It is released in the usual
way by pressing the spring, 14, in by means of the finger.
The outer parts of the ribs, 17, are made hollow or substantially so, a longitudinal
opening, 18, being left to allow the pivoted ear, 19, to pass through and slide
easily back and forth with the inner part of the rib, 20, to which it is attached or
forms a part of it.
The ribs, 17, are pivoted, to the top portion, 21, in the usual and well
known way.
To the ears, 19, on the inner ribs 20, are pivoted as usual by pins 23, see
Figure 2, the braces, 22, and the opposite end of the braces are pivoted in the
ordinary manner to the ears, 24, on the top of the runner, see Figure 5.
This frame when completed is covered with any suitable flexible material, such as
silk, cotton, or the like.
When it is desired to open the umbrella as indicated in Figure 1, the telescopic
stick is extended until the spring, 5, moves into the slot, 7, and the runner is
pushed up until the spring, 14, passes out under it, the inner ribs, 20, are also
drawn out until the cover becomes taught, and the umbrella is ready for use.
When it is necessary to close it, the spring 5, is pushed in as hereinbefore mentioned
which operation releases the part of the stick and allows it to pass down into the
part 2, thereby causing the spring, 14, to be forced in so as to release the runner
and permit it to be brought down over the stick, 2, the inner ribs, 20, are also
pushed up thereby bringing the whole into a small compact form substantially as
shown in Figure 4.
The umbrella can be used as a walking stick if desired by simply pushing in the
spring 14, and letting the runner down and closing it without telescoping the stick
or pushing the ribs, 20, up, the usual spring 26 holding the runner, 11, down.
In this way it can be used as an ordinary umbrella in place of a walking stick
if desired.
We are aware that extensible umbrellas have hereinbefore been used. We
therefore do not claim such construction broadly.
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 wo
claim is :-
In a folding umbrella, the combination with the extensible ribs the braces and
runner, of a telescopic stick composed of two tubular sections one of which is
provided with a longitudinal groove, the other, with a feather adapted to fit in said
grooves to prevent one from turning around on the other a spring, 14, secured to
the inner section for holding the runner in its upward position when the umbrella
is opened, a spring catch, 5, for holding the two sections of the stick in position

page_text: when extended and a spring catch, 26 for holding the umbrella closed while the
two parts of the stick are extended whereby the umbrolla can be used as an
ordinary umbrella for a walking stick when closed or the two parts of the stick it
can be adjusted into a small compact form by releasing the spring 5 and telescoping
5 the said parts substantially as described.
