Year: 1877

page_text: LETTERS PATENT to William Leggoe, of Rotherham, in the County of York, for
the Invention of "AN IMPROVEMENT IN THE MANUFACTURE OF UMBRELLA
AND PARASOL FRAMES,"
Sealed the 14th December 1877, and dated the 19th September 1877.
PROVISIONAL SPECIFICATION left by the said William Leggoe at the Office
of the Commissioners of Patents on the 19th September 1877.

"AN IMPROVEMENT
This Invention, which relates to a new, simple, and useful improvement in the
manufacture of umbrella and parasol frames, consists in providing an improved
middle bit and single-ended stretcher for such frames.
The improved middle bits are stamped or cut from sheet metal, or are otherwise
suitably shaped or made, so as when they are clamped round the ribs of the frame
they will project inwards and form side extensions or bearings for the outer ends of
the stretchers, which, at this part, are made with eyes which enter between the side
extensions of the middle bits and are rivetted thereto. By this improvement there
is no projection of the stretchers beyond the ribs, which is an important advantage,
as it prevents the damaging or chafing of holes in the silk or other covering of the
umbrella or parasol, which is generally caused by and is a source of constant trouble
with the ordinary forked ends of the stretchers, which slightly project beyond the
ribs and very soon damage the covering of the umbrella or parasol

WILLIAM LEGGOE, of Rotherham, in the. County of York. "AN IMPROVEMENT
IN THE MANUFACTURE OF UMBRELLA AND PARASOL FRAMES."
This Invention, which relates to a new, simple, and useful improvement in the
manufacture of umbrella and parasol frames, consists in providing and in the
application and combined use of an improved middle bit and single-ended stretcher
in such frames. The improved middle bits and stretchers are illustrated in Figures
1 to 4 of the accompanying Sheet of Drawings, and in their application to an
umbrella or parasol frame in Figure 5.
The improved middle bits 1 are stamped or cut from sheet metal of the shape
illustrated in Figure 1, the parts 2 of which, when they are clamped round the ribs
3 of the frame, project inwards of the ribs, so as to form side extensions or bearings
for the outer ends 4 of the stretchers 5, which are made single-ended, so as to enter
between the side extensions of the middle bits, to which they are rivetted, the rivets
passing through eyes in the stretchers and in the middle bits.
The stretcher may be made of wire of any suitable section, flat, as shown in Figure
2, round, as shown in Figure 3, or square, as shown in Figure 4. Their inner ends
6 are secured, as usually, by a wire to the notched rim 7 of the runner 8.
By this improvement there is no projection of the ends of the stretchers either at
the sides of or beyond the ribs, which is an important advantage, as it prevents the
damaging or chafing of holes in the silk or other covering of the umbrella or parasol,
which is generally caused by and is a source of constant trouble with the ordinary
forked ends of the stretchers which project at the sides of and slightly beyond the
ribs, and by constant abrasion very soon damage the said covering.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I would remark in conclusion that I claim as my Invention the provision and
application in combination to the frames of umbrellas and parasols of improved
middle bits, which are clamped round the ribs, and are formed with inner projecting
bearings or side extensions between which the outer ends of the stretchers, which
are formed single-ended, are entered and secured by rivets, with the object of
preventing the usual damaging or chafing of holes in the covering of the umbrella
or parasol caused by the usual projecting or forked stretchers, substantially as
described, and as illustrated on the annexed Drawings.
In witness whereof, I, the said William Leggoe, have hereunto set my hand
and seal, this Sixteenth day of March, in the year of our Lord One thousand
eight hundred and seventy-eight.
WILLIAM LEGGOE (L.S.)
