I, FREDERICK DIGHTON STAMMERS of 5 Philip Lane, London Wall, E.C.,
Commission Agent, do hereby declare the nature of this invention to be as
follows:-
According to the present invention I construct upon the tip portion of umbrella
& parasol ribs of grooved sections, i.e., upon that portion of the rib extending from
the loop or eye to which the cover is fastened, to the extremity that terminates in
a ball or otherwise, & between such loop or eye & extremity, a projecting collar or
shoulder, by which means the steel or other metal of which the ribs may be made,
both above & below the collar, becomes denser so that a degree of solidity &
strength hitherto unattained is secured to the rib at the point named; also, in the
case where the eye is formed of a loop of wire, the wire becomes gripped under the
process of constructing the collar or shoulder, to such an extent that all tendency
of the wire to get out of position from any cause whatsoever is entirely obviated;
& further the diameter of the rib above the collar & below the ball, is so reduced
as to admit of an improved construction of ball, & greater facility for the draining
of the tip or ball end of the rib, in connection with the process of japanning or
coloring or plating of the same, so that the risk of corrosion, with its attendant
The collar can be constructed
unsightliness & expense is reduced to a minimum.
upon the rib itself by any convenient known method for the purpose; or tips with
a collar of any desired design can be made separately & then attached to ribs by
any suitable means.

I, FREDERICK DIGHTON STAMMERS of 5, Phillip Lane, London Wall, E.C.,
Agent, 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 :-
According to the present invention, I construct upon the tip portion of umbrella
& parasol ribs of grooved or hollow sections, i.e., upon that portion of the rib
extending from the loop or eye to which the cover is fastened to the extremity that
terminates in a ball or otherwise, & between such loop or eye & extremity a
projecting collar or shoulder letter A, Fig. 1 by which means the steel or other
metal of which the rib may be made, both above & below the collar becomes
denser, so that a degree of solidity & strength hitherto unattained is secured to the
rib at the point named; also, in the case where the eye is formed of a loop of
wire, the wire becomes gripped under the process of constructing the collar or
shoulder to such an extent that all tendency of the wire to get out of position from
any cause whatsoever is entirely obviated; & further, the diameter of the rib
above the collar & below the ball, is so reduced as to admit of an improved

the rib in connection with the process of japanning or coloring or plating of the
same, so that the risk of corrosion with its attendant unsightliness & expense, is
reduced to a minimum. In addition, the collar or shoulder may be regarded as an
external means by which an umbrella or parasol maker, or maker of the frame only
of the articles named may be able to identify his particular manufacture: & where
the collar is used for this purpose, it may be colored, if desired, by any suitable
means, so as to be more distinctive; if preferred, however, a simpler form of collar
could be adopted for this particular purpose, riz. -a white or colored band could
be painted or printed or otherwise similarly marked round the rib see Fig. 2
letter B, in which case the form of rib in general use need not necessarily be subject
to any structural alteration. The collar can be constructed from the metal itself
or other material of which the rib may be made, or by additional metal or other
material being secured round the neck of the rib by any convenient known method
for the purpose; or, tips with a collar of any desired design see Fig. 3 letter C, can
be made separately & then attached to the rib by any suitable means.
invention does not apply to umbrella ribs made from solid wire, but is confined to
ribs made from trough or hollow wire.
This
Having now particularly described and ascertained the nature of my said
invention & in what manner the same is to be performed, I declare that what I
claim is
The projecting collar or shoulder referred to, which adds solidity & strength
& consequently, durability to the rib; also, a collar or band or any semblance of
the same, marked round or otherwise upon, or added to, the neck of the rib by any
suitable means.
