Improvements in the Manufacture of Runners and Top Notches or
Nuts for Umbrellas and the like.
A communication from abroad by ALEXANDRE DELATOUR, of Paris, in the Republic
of France, Umbrella Manufacturer.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street, Manchester, both in
the County of Lancaster, & 323 High Holborn, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
.
This invention has for its object an improvement in the manufacture of runners and
top notches or nuts for umbrellas and the like by a process of stamping, by means of
which two runners may be produced from one disc of metal, or one runner and one
top notch, according to the original diameter of the said disc. This is effected with-
out any soldering or bezil setting, and the finished article is equal, if not superior,
in quality to similar articles as at present produced by means of soldering, stamping,
setting or casting.
A disc of malleable metal is punched, rolled, hammered, or otherwise formed into
a tube, having an external flange round each end.
This tube is divided transversely into two parts, each of which is afterwards
finished off to form a top notch or runner according to its length.
The flanges above mentioned may be grooved circumferentially and slotted to form
the rings for the reception of the ribs and attachments.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Runners and Top Notches or
Nuts for Umbrellas and the like.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E. of the Agency for Foreign
Patent Solicitors, 6 Lord Street Liverpool and 6 Bank Street Manchester, both in the
county of Lancaster and 323 High Holborn in the county of Middlesex, civil engineer
(a communication to me from abroad by Alexandre Delatour, umbrella manufacturer,
80 Rue Réaumur, Paris, France, 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 has for its object an improvement in the manufacture of runners
and top notches or nuts for umbrellas and the like by a process of die stamping, by
means of which two runners (or one runner and one top notch), may be produced
from one single disc of metal. This is effected without any soldering or setting and
the finished article is equal, if not superior in quality, to similar articles as at
present produced by means of soldering, stamping, setting or casting.
For the proper comprehension of the improved manufacture herein described,
there is hereto appended a sheet of explanatory drawings in which are shown the
successive phases for the manufacture, from one blank, of one runner and one top
notch.
Fig. 1 shows in sectional elevation, a blank which has been produced from a
sheet of metal, (brass, for instance) by a combined operation of punching out and
stamping, this operation being known in the art of stamping.

page_text: Fig. 2 to 7 inclusive show the blank after the progressive stamping operations
which it has undergone for transforming it from the shape shown in fig. 2 to that
shown in fig. 7.
When the blank has been drawn so far as to assume the shape shown in fig. 7,
the stamping operation is stopped and the blank is cut on the line a a so as to
form two parts of which one, shown in fig. 8, is intended to form a top notch or
nut and the other, shown in fig. 9, is intended to form a runner.
The blank shown in fig. 9 is subjected to the action of dies which give a suitable
shape to the flange b, as shown in fig. 10. In this state, the blank is ready to
undergo the ordinary well known finishing operations, for converting it into a
runner, as shown in fig. 11.
The blank shown in fig. S is likewise subjected to a series of operations whereby
it is converted into a top notch. The first operation consists in punching a hole
into the top part, as shown in fig. 12; the second operation consists in widening the
opening and spreading the stock apart, as shown in fig. 13; the third operation
consists in finally stamping the blank between dies so as to assume the shape shown
in fig. 14. Finally the so formed blank is subjected to the ordinary operations,
such as turning, notching and polishing, for converting it into a finished top notch
or nut, as shown in fig. 15.
It will readily be understood that when it is desired to produce two runners
instead of the one runner and the one top notch described and shown, it will simply
be necessary to employ a blank presenting more stock than that shown in fig. 1.
Finally, it is to be understood that all the herein before mentioned operations
which a blank undergoes are well known in the art of stamping by means of dies
and therefore need no particular description.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what is claimed is :
The hereinbefore described method of manufacturing runners and top notches or
nuts for umbrellas and the like consisting in producing either a flat blank or a partly
stamped blank, as shown in fig. 1, in subjecting the said blank to successive stamping
or drawing operations until it acquires the shape shown in fig. 8, in separating the
blank so shaped either into two parts, each intended when finished to be converted
into a runner, or into two parts intended when finished to be converted into one
runner and one top notch, substantially as described and shown in the accompanying
drawing.
