IMPROVEMENTS IN UMBRELLA. FRAMES
Year: 1881

page_text: LETTERS PATENT to Gustav Neu, of King Square, in the County of Middlesex,
Scientific Engineer, for an Invention of "IMPROVEMENTS IN UMBRELLA.
FRAMES"
:
PROVISIONAL SPECIFICATION left by the said Gustav Neu at the Office of
the Commissioners of Patents on the 19th March 1881.
GUSTAV NEU, of King Square, in the County of Middlesex, Scientific Engineer.
"IMPROVEMENTS IN UMBRELLA FRAMES."
This Invention relates to improvements in umbrella frames, the object of the
improvements being to so construct the joint and rib of the stretcher that when
the umbrella is closed the ribs shall be automatically locked or held against the
stretchers, whereby the use of the usual tip cap may be dispensed with.
. In carrying out my improvements I form the "gate" of spring steel, and on the
inner surface of each side of such "gate " I form a projection at right angles to the
axis of the "gate;" the end of the stretcher through which the joint passes is
formed on each side with a groove or slot corresponding with the said projections
in the "gate."
By this construction when the umbrella is closed the said projections in the
"gate" take into the grooves or slots in the end of the stretchers so as to hold or
lock the ribs and stretchers together and keep them against the stick.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Gustav Neu in the Great Seal Patent Office on the 19th August
1881.
GUSTAV NEU, of King Square, in the County of Middlesex, Scientific Engineer.

the improvements being to so construct the joint of the rib and stretcher that

when the umbrella is closed the ribs shall be automatically locked or held against
the stretchers, whereby the use of the usual tip cap may be dispensed with.
In carrying out my improvements I form the "gate" of spring steel, and on the
inner surface of each side of such "gate" I form a projection at right angles to the
axis of the "gato;" the end of the stretcher through which the joint passes is
formed on each side with a groove or slot corresponding with the said projections
in the "gate."
In order to make my Invention better understood I will proceed to describe the
same by reference to the accompanying Drawing, in which Figure 1 represents a
side elevation, Figure 2. a section, and Figure 3.a front elevation of part of a rib
and stretcher of an umbrella frame with my improvements applied thereto, and
shewing the position occupied by the parts when the umbrella is partly opened;
Figure 4 is a side elevation, and Figure 5 a front elevation shewing the position
the said parts occupy when the umbrella is closed; Figures 6 and 7 are detached
views of the spring "gate;” and Figures 8 and 9 are detached views shewing
the end of the stretcher. Similar letters in all the Figures represent similar
parts.
a is the "gate," which I make of spring steel and pass the same over the rib f
and rivet or otherwise fix it thereto; b is the projection formed, by stamping or
otherwise, on the inner surface on each side of the said "gate" and at right angles
to the axis thereof; c is the stretcher; d is the groove or slot formed on each side
of the end of the stretcher c, through which the joint pin e passes; the said grooves
or slots d correspond with the said projections b in the "gate" a, but are placed at´
a slight angle thereto so as to cause the spring "gate" to more firmly lock the
stretcher and rib together.
By this construction of joint it will be understood that when the umbrella is
closed the projections b on the "gates" a will take or spring into the grooves or
slots d in the ends of the stretchers c, and will thus hold or lock the ribs fand
stretchers c together and keep them against the stick of the umbrella, and the use
of the usual tip cap may be dispensed with.
Having thus described the nature of my said Invention, and the best means with
which I am acquainted for carrying the same into effect, I would have it understood
that I do not confine myself to the precise details herein laid down, as the same
may be varied without departing from the peculiar character of the Invention, but
what I do claim is,-
Firstly. The use of the improved spring joint hereinbefore described for the ribs
and stretchers of umbrella or like frames, arranged and operating substantially as
and for the purpose hereinbefore described and illustrated in the annexed Drawings,
or any mere modification thereof.
Secondly. The manufacture of umbrellas or like articles with frames, or frames
for umbrellas or like articles, having ribs and stretchers provided with joints.
constructed substantially as herein described.
In witness whereof, I, the said Gustav Neu, have hereto set my hand
and seal, this Seventh day of July, in the year of our Lord One thousand
eight hundred and eighty one,
