MONTAGUE HYAM of 33 Jewin Crescent in the City of London, "IMPROVE-
MENTS IN THE MANUFACTURE OF UMBRELLAS AND THE LIKE"
This invention relates to the construction or arrangement of certain parts of
umbrellas, parasols and the like, the chief features being as follows.
It is desirable to make the different parts and especially the ribs and stretchers
in such manner that they or any of them can be removed quickly and without
taking the umbrella entirely to pieces.
To this end I form a hook upon the inner end of the rib with the opening turned
upwards when the rib lics about horizontal, this hook tapes into a wire or other
suitable part of the rib-holder which may if necessary be specially constructed for
this purpose, When the rib is lowered down and the position it occupies when the
umbrella is finished and whether open or closed, the opening of the hook is turned
round more or less away from the stick so that the rib cannot fall out or be taken
out unless the rib is disengaged from the stretcher or otherwise freed―The stretchers
are fastened in a like manner, but the opening is generally not quite in the same
position and is turned downwards instead of upwards so that when the stretcher is
jointed to the rib, they prevent each other from coming out, but when separated
either or both can be easily removed. The runner is of course constructed so as to
be adapted to this form of stretcher.
In a modification the inner end of the rib or stretcher may when desired be
formed with a pin or crossbar or the like through it; the rib holder or runner is
divided the two parts screwing together and leaving an annular channel for the
ends of the ribs to work in, and slots being provided for the ribs to pass through.
If desired I make the hook, or its equivalent (say the crossbar or any other
suitable and piece) independently from the body of the rib or of the stretcher as the
case may be.
In such case the material for the rib or stretcher when cut into suitable length
has the tips or ends, which as stated are separately manufactured, applied and
fastened thereto, say by placing the united parts into a die which by a blow or
pressure corrugates the same, or by soldering or in any other convenient manner.

page_text: In some cases the rib holder, in the runner, is divided and both parts are slotted
to accommodate the ribs or stretchers which may be of the construction described
in the preceding paragraph.
In putting these together the upper portion is turned over and the ribs or
stretchers laid in position and the other portion is then screwed up its slot being
clear of the ribs which lie in those of the upper portion. When the rib holder or
runner is turned over the ribs or stretchers drop into the slots in the lower portion
and are free to move therein as needed, so that it will be noticed that with this
arrangement a single rib or stretcher can be removed in a few moments without
disturbing the rest.
I find what is generally known as bayonette joint is a convenient form of
fastening for the cap which holds the cover in place upon the rib-holder, and is
much preferable to the usual method of rivetting it on; by this means it is securely
held, but can be removed in a moment when required.
A good method of securing the central ring to which the cover is fastened is to
form a suitable recess for it in the cap and spring it in or secure it there in a
convenient manner, such as forining a number of tongues inside the cap (those may
be punched out of the cap itself) and pressing them round the ring.
