PROVISIONAL SPECIFICATION.
Improvements in the Construction of the Frames of Umbrellas,
Parasols, and Sunshades.
I, HENRY JEFFERY of Stocksbridge Works near Sheffield, in the County of York,
Clerk, do hereby declare the nature of this invention to be as follows:-
This invention has for its object improvements in the construction of the frames of
umbrellas, parasols and sunshades and the improvements relate to the construction of
the end portion of the stretchers where they are jointed to the ribs.
Heretofore when the stretchers have been formed of "Paragon" or trough wire
with a three fork end the two outer prongs of the fork have been formed from part of
a thin piece of sheet metal which piece has been made to pass around the exterior of
the end of the stretcher just in rear of the fork and its edges have been bent over the
sides of the trough and made to pass into its interior so that each side of the trough
has been nipped by the thin metal. Consequently at the end of the stretcher where
the thin metal is wrapped around it the edges of the sides of the trough stretcher
close up to the fork have projected somewhat beyond the remainder of the side edges
of the trough so that the stretchers could not, along the whole of their length, lie
perfectly close to the ribs.
To remedy this we form a recess in the edge of each side of the end of the trough
wire of which the stretcher is formed, just in rear of the fork and where it is to he
embraced by the thin metal above mentioned and we make this recess of a depth
equal to the thickness of the thin metal so that when the thin metal piece has been
secured to the stretcher end the edges of the sides of the trough are continued in one
straight line right up to the point where the fork commences.

1, HENRY JEFFERY of Stocksbridge Works, near Sheffield in the County of York,
Clerk, 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 has for its object improvements in the construction of the frames of
umbrellas, parasols and sunshades and the improvements relate to the construction of
the end portion of the stretchers where they are jointed to the ribs.
Heretofore when the stretchers have been formed of trough wire with a three fork
end the two outer prongs of the fork have been formed from part of a thin piece of
_sheet metal which piece has been made to pass around the exterior of the end of the
stretcher just in rear of the fork and its edges have been bent over the sides of the
trough and made to pass into its interior so that each side of the trough has been
nipped by the thin metal. Consequently at the end of the stretcher where the thin
metal is wrapped around it the edges of the sides of the trough stretcher close up to
the fork have projected somewhat beyond the remainder of the side edges of the
trough so that the stretchers could not, along the whole of their length lio perfectly
close to the ribs.
To remedy this I form a recess in the edge of each side of the end of the trough
wire of which the stretcher is formed, just in rear of the fork and where it is to be
embraced by the thin metal above mentioned and I make this recess of a depth equal
to the thickness of the thin metal so that when the thin metal piece has been secured
to the stretcher end the edges of the sides of the trough are continued in one straight
line right up to the point where the fork commences.
Figure 1 of the drawings hereunto annexed is a side view of a three fork end of a
stretcher as heretofore made.
Figure 2 is a side view and Figure 3 a face view of a three fork end formed as
above described.
Figure 4 is a side view and Figure 5 a face view of the stretcher end before
the outer prong piece has been secured to it.
Figure 6 is a side view and Figure 7 a face view of the outer prong piece.
The recesses a which 1 form in each side of the trough wire near the end of the
stretcher is shewn clearly in Figure 4.
The recesses I form by putting the end of the stretcher into a grooved die then
bringing down upon it a punch the width of the recess-such punch having a tongue
on it which goes inside the stretcher to keep it to its proper opening.
The piece b for forming the outer prongs of the fork is then placed on to the
stretcher end and the edges of the portions 6 of the piece b are bent over the edges
of the sides of the trough just where the recesses a have been formed in them.

page_text: The bending over of the pieces 61 to make them clip the sides of the trough is
effected in the ordinary manner.
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. A stretcher of trough wire having a three fork end made with the edges of the
sides of the trough continued in one straight line up to the commencement of the
fork substantially as described.
2. A stretcher of trough wire having notches a near the fork end of the stretcher
within which the parts 6 of the piece blic substantially as described.
