PROVISIONAL SPECIFICATION.
Improvements in Strengthening and Repairing the Ribs and
Stretchers of Umbrellas and Parasols.
1, JOSEPH CROSS, of 29 Tangier Street, Whitehaven, Umbrella Manufacturer,
do hereby declare the nature of this invention to be as follows :—
The improvements relate to means for strengthening and repairing the ribs and
stretchers of umbrellas and parasols and have for object a ready mode of doing this
after manufacture, and also to enable repairs of ribs and stretchers to be made
without taking out the same.
To accomplish this and to effect my improvements I make strengthening pieces
or splicing pieces of steel to form a jacket or sleeve of any suitable length for
the ribs or stretchers requiring to be strengthened or repaired, and of a similar
form (by preference U shaped) to the rib or stretcher to be strengthened or
repaired.
These jackets or sleeves are fixed firmly to the ribs or stretchers by means of
small tubes or bent loops of thin metal being compressed thereon, with the aid of
any suitable tool, so as to follow the outline of the U rib or stretcher, and so
binding the same with the jacket and sleeve tightly together, thus readily and
rapidly effecting the strengthening or repairing operation.
Variations in the length, the shape, and material, forming the sleeve or jacket,
and also of the tubes or loops employed therewith, may be made without departing
from the peculiar character of the invention.

COMPLETE SPECIFICATION.
Improvements in Strengthening and Repairing, the Ribs and
Stretchers of Umbrellas and Parasols.
I, JOSEPH CROSS, of 29 Tangier Street, Whitehaven, Umbrella 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:-
The improvements relate to means for strengthening and repairing the ribs and
stretchers of. umbrellas and parasols, and have for object a ready mode of doing
this after manufacture, and also to enable repairs of ribs and stretchers to be made
without taking out the same.
To accomplish this and to effect my improvements, I make strengthening pieces
or splicing pieces of steel, to form a jacket or sleeve, of any suitable length, for the
ribs or stretchers requiring to be strengthened or repaired, and of a similar form
(by preference. U shaped) to the rib or stretcher to be strengthened or repaired.
These jackets or sleeves are fixed firmly to the ribs or stretchers by means of
small tubes or bent loops of thin metal being compressed thereon, with the aid of
any suitable tool, so as to follow the outline of the U rib or stretcher, and so
binding the same with the jacket and sleeve tightly together, thus readily and
rapidly effecting the strengthening or repairing operation.
But that the improvements may be better understood, I will, with the aid
of the accompanying drawings, proceed more fully to describe means employed
by me.

page_text: DESCRIPTION OF DRAWINGS.
Figs. 1, and 3, show elevations of a strengthening and splicing jacket or sleeve
supplied with clips, according to one form of my invention, and Figs. 2, and 4
show cross sections of the sleeve with a clip in elevation.
Fig. 5, shows a side elevation of a rib and stretcher, with the repairing attach-
ments, and
Fig. 6, an end elevation thereof, with the rib in section; whilst
Fig. 7, shows a perspective view of one form of tool employed for binding the
clips.
The same letters indicate corresponding parts wherever they occur.
a, a, are the splicing jackets or sleeves, and b, b, the bent loops or clips, but I may
employ in lieu thereof, as a modification of my improvements, a single tubular,
bent loop, or other clip of sufficient length to form the jacket or sleeve for
strengthening and splicing purposes.
In Fig. 2, the clip is shown in tubular or continuous form, whilst in Fig. 4, a
clip is shown with separated ends. In the former case the clip is secured by
pressing the upper surface into the hollow of the umbrella rib, and in the latter
case the ends of the clip are bent over the edges of the rib and pressed against the
inner sides thereof.
c, c, is an umbrella rib, and d, d, a stretcher, connected in the usual way by the
attachment e, e. 1, f, is a hand tool, employed for fastening the clips in position,
but it is obvious that other forms of tools may be substituted, and that machinery
may be employed in lieu of hand tools for the purpose.
Although, by preference, I employ umbrella ribs of U shape, as shown in the
drawings, the improvements are nevertheless applicable to ribs of other forms in
cross section, whether hollow or solid, by modification of the shape of the parts;
and the attachment of the clips to the sleeves and ribs may be effected in various
ways.
Variations in the length, the shape, and material, forming the sleeve or jacket,
and also of the tubes or loops employed therewith, may be made without departing
from the peculiar character of the invention.
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. In the repairing or strengthening of ribs or stretchers of umbrellas and
parasols, the employment of jackets or sleeves capable of receiving the broken ends
of umbrella ribs or stretchers, and firmly connected with such ends by means of
tubular or other formed clips for the purpose and in manner substantially as shown
and described.
2. In the repairing or strengthening of ribs or stretchers of umbrellas and
parasols, the employment of clip-jackets or sleeves, capable of receiving the broken
ends of umbrella ribs or stretchers, and securing the same by compression, for the
purpose and in manner substantially as herein described.
Dated this 18th day of June 1891.
