PROVISIONAL SPECIFICATION.
Improvements in the Frames of Umbrellas, Parasols, or Sunshades,
and in their Manufacture.
We, JOHN JEFFERY and JOHN SIMPSON both of the Stocksbridge Works near
Sheffield, in the County of York, Managers, do hereby declare the nature of this
invention to be as follows:-
The ribs we make of trough wire but wider than heretofore usual-the stretcher
we also form of trough wire but of a width to allow of its lying within the trough
rib. The git which is secured to the rib where the stretcher is to be jointed to it we
form of a piece of thin sheet metal bent around the exterior of the rib and its ends
doubled over and made to embrace and clip the two sides of the trough. The git
and rib are subsequently pierced for the joint pin to be passed through them.
The rib also near its tip end where it has to lie against the rim of the runner
when the umbrella is closed has two notches cut out from its opposite sides so that
the rib may lie close against the barrel of the runner.
By constructing the frames of umbrellas in the above manner the stretchers can
be made to lie entirely within the ribs when the frame is closed and a stronger and
smaller folding umbrella be obtained.
Dated this 10th day of January 1888.

Improvements in the Frames of Umbrellas, Parasols, or Sunshades,
and in their Manufacture.
We, JOHN JEFFERY, and JOHN SIMPSON, both of the Stocksbridge Works, near
Sheffield, in the County of York, Managers, 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 ribs we make of trough wire but wider than heretofore usual-the stretcher we
also form of trough wire but of a width to allow of its lying within the trough rib.
The git which is secured to the rib where the stretcher is to be jointed to it we form
of a piece of thin sheet metal bent around the exterior of the rib and its ends doubled
over and made to embrace and clip the two sides of the trough. The git and rib are
subsequently pierced for the joint pin to be passed through them.
The rib also near its tip end where it has to lie against the rim of the runner when
the umbrella is closed has two notches cut out from its opposite sides so that the rib
may lie close against the barrel of the runner.
By constructing the frames of umbrellas in the above manner the stretchers can be
made to lie entirely within the ribs when the frame is closed and a stronger and smaller
folding umbrella be obtained.
Figure 1 of the drawings hereunto annexed shows part of the stick and runner
and one of the stretchers and ribs of an umbrella frame formed in the above manner.
Figure 2 shows separately the tip end of the rib with the notches formed in its
opposite sides where it lies against the runner. Figure 3 is a cross section of the rib
and stretcher. Figures 4 and 5 show two views of the joint connecting the stretcher
with the rib and Figure 6 is a cross section of the rib and git.
A is the rib, B the stretcher, C the runner and D the stick. A' are the notches
in the opposite sides of the rib where it lies against the end of the runner. E is the
git formed of a piece of thin metal bent around the rib and its ends doubled over
and made to embrace and clip the two sides of the trough wire of which the rib is
formed.
The piece of metal is first bent by dies to the required form and then slipped on
to its proper position upon the rib and clamped upon it by dies and afterwards pierced
to receive the joint pin as will be well understood.
The notches in the sides of the trough ribs may be formed by cutting away the
metal from the sides by means of cutting dies as will be well understood or they
may be otherwise suitably formed.
The improvement of forming such notches in the opposite sides of trough ribs
where they lie against the end of the runner is applicable not only to frames in
which trough stretchers are used which can lie within the ribs but also to other frames
in which trough ribs are used.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is —
1. A lock rib frame for unbrellas parasols and sunshades in which the ribs
are of trough wire wider than the stretchers so that the stretchers may lie within
the ribs.
2. Forming the git piece of such frames of a piece of thin sheet metal bent so as
to clasp the two sides of the trough rib substantially as described and piercing the
git and rib at one operation.
3. Forming notches in the two opposite sides of trough ribs of umbrella parasol
and sunshade frames where such ribs lie against the heads of the runners.
