I ALEXANDER MACMILLAN of 66 Holborn Viaduct in the City of London Umbrella
Manufacturer do hereby declare the nature of this inventon to be as follows:-
66
This Inventon relates to certain improvements upon the subject matter of Letters
Patent granted to me No. 1593 and dated the 3rd day of February 1886 for
Improvements in umbrella frames," whereby the object of strengthening the rib at
its joint with the stretcher is secured whilst the link piece will be capable of folding
within the hollows of the rib and stretcher in such manner that the umbrella may roll
"small" as is required for the "trade."
The stretcher at that part where the slot is formed, according to the Specification
of the Patent hereinbefore referred to, is to be stamped or formed upon its edges so as
bring the edges nearly together and so to form a slide for the neck of the link piece.
The link piece will be jointed at its outer end to a "gat" on the rib.
According to a modification of this construction a sliding piece or gat is applied to
the stretcher and the sliding end of the link piece is to be jointed to the gat in the
following manner, that is to say ;-
The gat is made of a strap of metal formed saddle-wise to lay over the back of the
stretcher the two ends of said strap being brought together with the end of the link
piece between said two ends of the strap and jointed thereto. The two ends of the
strap are then by means of a tool to be made for the purpose, pressed into the channel
of the stretcher so as to sink the ends of the strap and the joint of the link flush with
the thickness of the stretcher. By these means the link piece will when the frame is
closed lie neatly between the openings or channels of the stretcher and rib without
adding to the bulkiness of the frame.
This construction is equally applicable to the "lock rib" frame and to the
Paragon" frame.
In applying the slot and link piece to the "lock rib" frame the slot will be cut or
stamped in the stretcher and by a tool be stamped up so that two "nerves" or
strengthening edges will be formed to the slotted portion of the stretcher between
which edges of the slot the neck of the link piece will slide and the stretcher will be
strengthened at that point.

page_text: I ALEXANDER MACMILLAN of 66 Holborn Viaduct in the City of London 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 :-
This Invention relates to certain improvements upon the subject matter of Letters 5
Patent granted to me No. 1593 and dated the 3rd day of February 1886 for
Improvements in umbrella frames whereby the object of strengthening the rib at its
joint with the stretcher is secured whilst the link piece will be capable of folding
within the hollows of the rib and stretcher in such manner that the umbrella may be
rolled "small" as is required by the "trade."
In the drawings hereunto annexed Fig. 1 shows in side view the fitting of a
supporting-link to a stretcher formed upon its edges to furnish a groove or slide for
the link piece end. Fig. 2 is a plan view of the groove of the stretcher. Fig. 2ª is a
cross section at line "",
of Fig. 1. Figs. 3, 4 and 4" are like views to Figs. 1, 2
and 2ª but with a running "gatt or slide to which the link piece is jointed. The
section Fig. 4" is taken at line, y, of Figs. 3 and 4.
The stretcher a, at that part where the slot is formed according to the specification
of the Patent herein before referred to is to be stamped or formed upon its edges so
as to bring the edges nearly together and so to form a slide b for the neck of the link
piece c. The link piece will be jointed at its outer end d, to a "gatt" on the rib e.
According to a modification of this construction, a sliding piece or "gatt" b¹ is
applied to the stretcher a and the sliding end of the link piece c is to be jointed to the
gatt" in the following manner that is to say :-
The "gatt" is made of a strap of metal 61, formed saddle wise, to lay over the back
of the stretcher, the two ends 2, Fig. 4" of said strap being brought together with the
end of the link piece between said two ends of the strap and jointed thereto. The
two ends of the strap are then by means of a tool to be made for the purpose, pressed
into the channel of the stretcher, so as to sink the ends of the strap and the joint of
the link about flush with the thickness of the stretcher, by these means the link piece
will when the frame is closed lie neatly between the openings or channels of the
stretcher and rib without adding to the bulkiness of the frame.
This construction is equally applicable to the "lock-rib" frame and to the
Paragon" frame.
In applying the slot and link piece described under the herein before mentioned
Letters Patent to the lock rib frame, the slot will be made by a sharp cut in the
stretcher metal, and by a tool, the edges of this cut will be stamped up so that two
strengthening edges will be formed to the slotted portion of the stretcher,
between which edges of the slot, the neck of the link piece will slide and the stretcher
will be strengthened at that part. This is not shown in the drawings

page_text: The frames made according to this invention may have the stretchers fitted to the
ribs so as that when open there will be greater free space below the stretchers and the
greater liability of the umbrella turning inside out will be removed or counteracted by
the link piece.
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 :-
The Improvements in umbrella frames and running gatts consisting
Firstly In the stretcher a, the slide b, for receiving the end of the link-piece c, as
and for the purpose set forth.
Secondly-In combination with the stretcher, the running "gatt" b¹ fitted to
receive the end of the link piece e and to lie within the groove of the stretcher as
herein specified and shown by the drawings.
