PROVISIONAL SPECIFICATION.
Improvements in Umbrellas.
I, HENRI TAILLEFER, of Vincennes, France, Mechanic, do hereby declare the
nature of this invention to be as follows:-
In umbrellas constructed according to this invention the rib sinks into a hollow
or channelled portion of the stretcher.
According to one arrangement each stretcher is formed of a metallic rod of
U-shape in cross section. That end of the stretcher which is connected to the rib,
is formed with a recess into which enters a spring that is fixed to the rib and which
will be hereinafter referred to. Through two sinall holes which are formed in the
sides of the stretcher on each side of the recess are passed pins. At the other end
of the stretcher the sides thereof are cut away and the bottom portion is then bent
back upon itself in such a manner as to form a small eye.
The rib is also formed of a metallic rod of U-shape in cross section but of
somewhat less cross sectional area than the stretcher. In about the middle of the
length of the rib, there is arranged in the hollow of its section the spring above
referred to, the end of which is firmly fixed to the rib. The other end of this
spring is formed with a perforation into which enters one of the above mentioned
pins viz. the one which is nearest the outer end of the stretcher, in such a manner
that the said stretcher is connected to the rib.
When the umbrella is closed, the rib enters the hollow of the stretcher.
When
it is desired to open the umbrella, the spring rotates about the innnermost of the
two pins and the outer pin in sliding against the rib, moves the head of the spring
away from the rib; the tension of this spring has then a constant tendency to
bring the stretcher back to the rib, that is to say, to close the umbrella.
The head or upper end of the rib is made of a peculiar form, portions of the
sides of the rib being cut away, the remaining portions of the sides being pressed
together; the bottom part of the rib, which has been left full length, is then bent
back so as to form a small eye into which is passed the wire which connects
all the ribs together.
Near its lower end the rib is upset and thinned in order that the entrance
of the rib into the stretcher when the umbrella is being closed, shall not be
interfered with by the end of the latter.
Instead of the spring arrangement above described, any other arrangement for
connecting the stretcher to the rib may be employed.
Dated this 5th day of September 1892.

COMPLETE SPECIFICATION.
Improvements in Umbrellas.
I, HENRI TAILLEFER, of Vincennes, France, Mechanic, 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 the frames of umbrellas and is illustrated in the annexed
sheet of drawings.
Figs. 1 to

represent an improved construction of stretcher according to my
This stretcher is formed of a metal rod of U-shape in cross section as indicated
[Price 8d.1

page_text: in Fig. 3. The end which is connected to the rib is formed with a slot A B
(Fig. 1) in which a spring that is fixed to the rib and which will be hereinafter
described, enters. CD are two small holes in which are fixed two pins F E. The
other end of the stretcher is formed with a small eyelet G (see Fig. 4) made by
cutting away the sides of the U-shaped rod as indicated in Fig. 5, and then rolling
back on itself the bottom part G¹.
Figs. 7 to 13 represent an umbrella rib according to my invention. This is also
formed of a metal rod, likewise of U section as shewn in Fig. 7 but of somewhat
smaller size in cross section than the stretcher. At about the middle of its length,
there is arranged in the hollow of its section the spring H (Fig. 8) above referred
to the end of which is firmly fixed to the rib and whose other end J is formed
with a perforation through which passes the small pin E, the stretcher being thus
united to the rib as shewn in Fig. 9.
When the umbrella is closed, the rib lies in the hollow of the stretcher, as shown
in Fig. 10 so that there is no external projection. When opening the umbrella,
the stretcher turns about the pin E and the pin F, sliding along the rib (Fig. 9)
causes the free end J of the spring to move further away from the rib so that the
tension of the spring acting on the pin E always tends to place the stretcher parallel
to the rib, in other words to close the umbrella.
Fig. 6 shews an arrangement in which part ab of the stretcher forms the spring
and Fig. 14 illustrates how I construct the rib with which such a stretcher is used.
In this case the rib instead of being of the section indicated in Fig. 7, is of the
circular section shewn in Fig. 14 at d and to a larger scale at the right hand side
of Fig. 15.
c is a small piece of metal, of the cross sectional form shewn in Fig. 15, which is
an enlarged end view. It is placed in position on the rib by introducing its
rounded part into the open end of the rib before the ends of the latter are turned
back; it is then slidden along the rib to the point at which it is to be fixed. To
retain the piece e in position, a small rivet e is passed through holes made both in
the rib and in the piece c. The piece c is cut away so as to leave a small shoulder f
against which the spring a of the stretcher abuts.
Fig. 16 represents an arrangement somewhat resembling that shown in Fig. 14,
but differing from it in that the stretcher is not provided with a spring.
By reason of the peculiar form of the rib d (Figs. 14 and 16) it is sufficient to
fix the piece c by means of the rivet e without any other securing means except that
afforded by the friction between the edges of the rib and the piece c.
The head or jointed end of the rib is of the special form represented by Fig. 11
to obtain which the side portions L M of the metal rib are cut away as indicated
by Fig. 12, then the shortened side portions L and M are turned over in an inward
direction and the free end or tongue N is turned over on itself to produce a small
eye O through which the wire which holds together all the ribs is passed.
Or the head or jointed end of each rib may be of the forin indicated by
Fig. 17.
The other end of the rib is of the form shewn in Fig. 13 being recessed or
compressed at P so as to accommodate the runner to which the stretchers are
connected and thereby permit the ribs and stretchers to lie closer together than
would otherwise be the case.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. An umbrella frame comprising ribs having springs H to which the stretchers
are fastened the arrangement being such that the springs constantly tend to cause
the ribs and stretchers to move into their closed position substantially as described.
2. An umbrella frame comprising ribs provided with pieces c and stretchers
whose ends are formed with springs which abut against the pieces c substantially as
described for the purpose specified.

page_text: 3. An umbrella frame in which the ribs of U or circular section are recessed or
compressed as at P Fig. 13, to accommodate the runner to which the stretchers are
connected and permit the ribs and stretchers to lay close together substantially as
described.
4. Umbrella frames constructed substantially as herein before described with
reference respectively to and shown in Figs. 1 to 5 and Figs. 7 to 12 inclusive; in
Figs. 6, 14 and 15; and in Fig. 16 of the drawings annexed.
