COMPLETE SPECIFICATION.
An Improved Fastener for Application to Umbrellas and Sunshades.
I CARL AUGUST PFENNING of Barmen-Rittershausen, Rhenish Prussia, in the
Empire of Germany, Manufacturer, 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 and accompanying drawings:
My said invention relates to an improved fastener for application to the binders
of umbrellas, sunshades and the like.
In its main characteristics the present fastener is similar in construction to a
fa-tener for which I have already obtained Her Majesty's Letters Patent No. 14073
of 1892 the said former fastener having been specially designed for application to
gloves, gaiters and other articles of dress.
'
The utilising of this fastener for the purpose of securing umbrellas and sunshades
instead of the old fashioned button and ring, will be evident to manufacturers and
my present invention refers to such special application and to the modifications in
the fastener rendered desirable by its new use.
The annexed sheet of drawings clearly illustrate my invention.
Fig. 1 is a view of the upper part of an umbrella or sunshade to the binder of
which my improved fastening is applied both at the usual place at the top of the
folds (as at A) and also at the rib tips in the position marked B where it takes the
place of the usual rubber or metal confining ring. The confining ribbon or binder
is marked u, the tag for operating the fastener is marked .
The fastener itself is
illustrated to a larger scale by the remaining figures on the sheet.
The fastener is
composed of two parts, an under and an upper part, and is upon the spring snap
principle as is the case with my former fastener already referred to.
The upper part
with spring snap recess and also the under part with grooved button a to snap into
the recess are shown in Fig. 2. The upper part which is to the left hand in
the fig. consists of a hollow disc compo ed of the bottom g which is shown separately
at Fig. 5 and the cover k, the two parts being held together by the cylindrical
eyelet or short tube d which might either he in one with the bottom g, or might be
Sparate from both. Within this hollow disc is the spring lever having a toe
which enters the short tube d through a slit in the side so as to engage with the
button a when it is pushed in. The lever is governed by a circular or double
curve spring contained within the hollow disc, the tendency of the spring being to
maintain the toe of the lever / constantly thrust through the slit in the short
tube d. To the end of the lever hand passing through the slot o I attach a tag r
to pull the lever back when it is wished to release the button a. An eyes (shown
more plainly in Fig. 4) which is secured to the top k or the bottom g of the hollow
disc, serves to receive the fast end of the ribbon which binds the umbrella or
sunshade when rolled up as in Fig. 1.
The under half of the fastener consists of the grooved button a having a flared
foot as shown. The other end of the ribbon is securely held between the top
plate and the bottom plate <<. The ribbon u is doubled to give a better hold to
the plates and the looped or doubled end of the ribbon receives a bar or buckle or
other means m which enables the ribbon to be more securely sewn or otherwise
secured to the material of the umbrella or sunshade. The use of the fastener will
now be easily understood. The umbrella or sunshade being rolled up, the upper
half of the fastener is pressed upon the lower half and the button a snaps into the
tube d, the spring toe yielding before the rounded top of the button and snapping
into the groove in the button when it comes opposite to the toe.
じ

page_text: To release the halves of the fastener, the tag is pulled so as to pull back the
lever and thus withdraw the toe from the groove. The halves will then
come apart.
Figs. 6, 7, 8 and 9 show modifications in the construction of the fastener. In
Fig. 6 the lever h¹ is of a modified shape. In Fig. 7 the lever his pulled to one side
instead of being pulled out as in Fig. 3. In Fig. 8 the lever is of a forked shape
the arms projecting through each side of the hollow disc.
The upper part of the fastener as herein before described is open at the top of the
short tube d. I might however make a hollow disc which would be closed or boxed
in at the top. To do this I must make the two halves of the hollow discs in such a
manner as to engage with each other. This I do by forming a lip on the edge of the
bottom g and then turning over and pressing down the edge of the cover so that
the two halves are practically rivetted together. This renders them independent of
the tube as a rivetting means so that I can stop the tube short at the inside
of the cover which is then closed in all over. This makes a neater top to the
.fastener.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
The application of spring snap fasteners of the indicated nature or substantially
of the same nature and construction to the confining ribbons or bands of umbrellas
and sunshades, as hereinbefore described and as illustrated.
