PROVISIONAL SPECIFICATION.
Improvements in the Construction of Umbrella-frames.
I CHARLES MAIDMENT, of Hinks Mill House, Mere, in the County of Wilts
do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in the construction of umbrella frames and
has for its object an improved form of notch wherein the ribs and the stretchers
may be fixed in such a manner that if a rib or stretcher breaks, the same can be
immediately replaced by a sound one, without interfering with the adjoining ribs or
stretchers.
In carrying my invention into practice I provide the outer edge of the runner
notch and the top notch, with a number of centrally split or recessed projections
corresponding to the number of stretchers and ribs in the umbrella.
According to my invention I provide the outer periphery of the top notch and
runner notch, respectively, with a row of centrally recessed projections, arranged at
equal intervals one from the other. Within the recesses of the said projections are
secured the perforated inner ends of the ribs and stretchers, respectively, by means
of headed pins, the free ends of which may be rivetted or turned down.
To fix the inner and perforated end of a stretcher or rib, the same is placed in
the central recess of one of the projections aforesaid, and a pin is passed through
the perforated end of the said rib or stretcher.

COMPLETE SPECIFICATION.
Improvements in the Construction of Umbrella-frames.
I CHARLES MAIDMENT, of Hinks Mill House, Mere, in the County of Wilts,
Umbrella Maker, 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 :-
My invention relates to improvements in the construction of umbrella frames and
has for its object an improved form of notch wherein the ribs and the stretchers
may be fixed in such a manner that if a rib or stretcher breaks the same can be
immediately replaced by a sound one without interfering with the adjoining ribs or
stretchers.
In carrying my invention into practice I provide the outer edge of the runner
notch and of the top notch with a number of centrally split or recessed projections
corresponding to the number of stretchers and ribs in the umbrella.
In the accompanying drawings in which like letters of reference indicate corre-
sponding parts throughout the figures,
Fig. 1 is a view illustrating my improvements.
Fig. 2 is a plan of the top notch and
Fig. 3 is a section on line of Fig. 1.
According to my invention I provide the outer periphery of the top notch and
runner notch n and n', respectively, with a row of centrally recessed projections p
arranged at equal intervals one from the other. Within the recesses of the said
projections are secured the perforated inner ends of the ribs b and stretchers o
respectively by means of headed pins h the free ends of which may be rivetted or
turned down.

page_text: To fix the inner and perforated end of a stretcher or rib the same is placed in the
central recess of one of the projections aforesaid and a pin is passed through this
projection and through the perforated end of the said rib or stretcher. The ribs or
stretchers secured in this manner are much stronger than those fixed according to
the old method, while whenever it becomes necessary to replace of one of these ribs
or stretchers the pin is withdrawn from the corresponding projection and the
damaged or broken rib is removed, a new rib being inserted in the same recess and
the pin replaced, an operation which can be readily performed in a few minutes
without interfering in any way with the adjoining ribs or stretchers as would be the
case when they were all secured by one wire as heretofore.
Another advantage of my improvements is that the cover is not so liable to be
damaged.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is
1. In umbrella frames the combination of the recessed projections p with the
top notch and the pins substantially as herein described and shown in the
drawings.
2. In umbrella frames the combination of the recessed projections p with the
runner notch n¹ and the pins h substantially as herein described and shown in the
drawings.
3. In umbrella frames the combination with the notches on the recessed
projections p, p each of which is designed to receive the perforated inner end of one
of the ribs or stretchers secured therein by a pin substantially as herein described
and shown and for the purpose set forth.
