This invention relates to an improvement in umbrellas, sunshades, and umbrella-
tents or shades; and the object of the invention is to provide simple means whereby
the ribs may be readily removed for repair.
By this invention, the ribs are formed with à T-shaped head which works in an
annular groove formed in an enlargement on the stick, and the heads are retained
in the groove by a disc of thin metal resting on and secured to the enlargement
in such manner that its edge which is serrated to form openings for the ribs to
project through, can be bent up over the groove.

An Improvement in Umbrellas, Sunshades, and the like.
We, FREDRICK SCHAEFER, and ADAM SCHAEFER, both of No. 21, West Fourth
Street, Williamsport, Pennsylvania, U.S.A., Umbrella Menders, 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 an improvement in umbrellas, sunshades, and umbrella
tents or shades; and the object of the invention is to provide simple means whereby
the ribs may be readily removed for repair.
Reference being had to the accompanying drawings, Fig. 1 shews so much of an
umbrella frame as will serve to illustrate my invention. Fig. 2 is a top plan of the
sliding ferrule, or a view shewing the underside of the boss hereinafter referred to;
and Fig. 3 is a vertical section thereof. Fig. 4 is a part sectional plan of the
ferrule or boss shewing the ribs or stretchers in place.
an annular
The frame comprises the stick 1, to which is secured the boss 2 having
groove 3 and flange 4 which is radially serrated as shewn at 5, Fig. 2, to form
tongues 6.
The ribs 7 and stretchers 8 are formed with T-shaped heads 9 which lie in the
groove 3, the ribs or stretchers projecting through the serrations 5, and are kept
in place by the tongues 6 which are bent over them as shewn in Figs. 1 and 4.

page_text: The sliding ferrule 10 is similar in construction to the boss 2 and needs no
separate description.
In order to remove a broken rib or stretcher it is only necessary to bend up one
of the tongues 6 and the rib or stretcher can be readily removed.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
I claim is:
In an umbrella, sunshade, or umbrella tent having the stick provided with a fixed
boss and a sliding ferrule, an annular groove in said boss and ferrule respectively,
a flange projecting from the edge of said grooves, radially arranged serrations in
the flanges forming tongues, the ribs and stretchers formed with T-shaped heads
adapted to lie in the annular groove in the boss and ferrule respectively, and capable
of being secured therein by the tongues which are bent over the T-heads sub-
stantially as and for the purposes herein before set forth.
