An Improved Combined Runner and Rib-holder for Umbrellas
and the like.
I, CASPAR WILHELM BREMSHEY, of the firm of Bremshey and Co., manufacturers
of umbrella frames, in Ohligs, Rhenish Prussia 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 :-
Among the usual umbrella frames, there are frames with long stretchers and frames
with short stretchers. For keeping the first named frames closed, a runner has
hitherto been employed in which the downward closing motion thereof, causing the
ribs to hold together, is effected by means of a spring inside the runner.
Among the umbrella framnes having short stretchers, the closing of the umbrella is
effected by the usual spring, let into the stick itself and the ribs are held together by
a runner secured to the stick and grasping the ribs.
By means of the improvement to be hereinafter described, we provide a simple and
effective runner for umbrella frames having long stretchers; this runner not only
effects the closing of the frame, but also acts to hold the ribs together, without the use
of any spring in the runner.
In all runners hitherto known for frames having long stretchers, the said runners
acting both to close the umbrella and to hold the ribs together and being movable on
the stick, there is always a spring, which presents many inconveniences. According
to our improvement which fulfils all the above mentioned functions, there is no
spring; the absence of said spring is an essential advantage, the more so as the runner
may receive a form most suited to its work.
In the drawing:

Fig. 2 is an elevation of the runner, open.
Fig. 3 is a section through xy (fig. 5).
Fig. 4 is a plan of fig. 1, and
Fig. 5 is an underview of the improved runner.
The runner is composed of the slide piece a capable of being moved along the
atial to the clide piece is scoured a
having

page_text: are fastened a rib in the usual manner. Onto the slide a is placed the movable
runner c in such a manner that by the friction between a &c, the latter can be set in
any desired position.
In order to properly guide the runner c and to obtain as much friction as possible
against the slide piece a, the runner is provided with a sleeve d, thus allowing the
runner c to be displaced to such an extent that it projects above the ribs.
The height of the runner should be such that when the same is completely brought
down upon the slide piece a, the crown of the latter as well as the ribs of the umbrella
frame, remain free, see fig. 1.
The downward motion of the runner c is limited by a rim on the slide piece a.
The umbrella is held open by a spring in the stick, in the usual way.
Operation. In order to open the umbrella, the runner is brought down into its
extreme position, whereby the ends of the ribs and the crown of the slide piece a with
the stretchers secured thereto, are free. The slide piece a and runner c are caused to
slide together, on the stick, until the slide piece a has passed beyond the spring let
into the stick and the umbrella is opened.
In order to close the umbrella, the spring in the stick is depressed, the slide piece
and runner are brought down completely and after the ribs have been laid against the
stick; the runner is pushed over the ends of the ribs.
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 we claim is:-
In the kind of umbrellas having long stretchers, and held open by a spring secured
in the stick, the employment of a runner capable of sliding on the stick, composed of
the slide piece a having a crown for receiving the stretchers and of the runner c
movable on the slide piece a and provided with a sleeve d, by means of which parts a
the umbrella can be closed and the ribs are held together, without the use of
and
C,
any spring.
