PROVISIONAL SPECIFICATION.
Improvements in Fittings for Umbrellas, Parasols, Tent Poles,
and the like.
I, JOHN JOHNSON of Grange Road East, Middlesbrough, Yorkshire, Contractor,
do hereby declare the nature of this invention to be as follows:-
My improvements consist in making a special form of runner with top notch
connections for the ribs and stretchers, applicable to the tubular fittings of umbrellas,
parasols, hell-tents and the like.
An annular hoop is fixed temporarily on the top of the runner tube, and the
bottom end of the top notch tube is fastened down on to an annular lead seating
formed outside, below the top notch fitting. By means of the hoop a chamber is
formed round the outside of the runner and top notch tube. Into the right and
left band faces of these hoop slots are cut to receive the enlarged heads of the ribs
and stretcher bars. These heads have side projections or enlargements so that they
cannot be withdrawn through the front or face of the slot. I thus dispense with
the wires and V shaped notched hoops now in use and secure the ribs and stretchers
by means of soldering the hoops in which they work.
I then apply the usual cotton or leather covering to the joint, thus obtaining a
good strong and cheap working joint, which cannot collapse as the wire joint is
apt to do when corroded.

COMPLETE SPECIFICATION.
Improvements in Fittings for Umbrellas, Parasols, Tent Poles,
and the like
I, JOHN JOHNSON of Grange Road, East Middlesbrough, Contractor, 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 relates to the frames of unbrellas, parasols, tents and the like.
My improvements in the construction of frames for umbrellas, parasols, bell tents
and the like are designed to obviate the frequent damage caused by rusting and
sudden breaking of the wires by which the ribs of these articles are at present fixed
on to the V shaped slit ring on the top and runner tube.
My improvements chiefly consist in substituting hollow rings or annular chambers
for the present V shaped slit rings, by which the ribs and stretchers are held in
their places, whereby the use of tie wires is dispensed with and a firmer and more
durable connection of the said ribs and stretcher joints is secured, and in the means
I adopt for connecting the ribs and stretcher bars in position which are as follows.
I place an annular raised hoop or hollow ring which forms a chamber round the
outside of the runner or fixed tube; in which hoops, transverse slits are made, and
into these slits, the bulb ends, or bent ends of the ribs and stretcher bars are inserted.
This is effected by projecting each rib from the inside of the runner tube, through a
D

page_text: suitable aperture in the runner or fixed tube, into and through the annular chamber
aforesaid, the enlarged end being retained within the said chamber by which means
I obtain a safe, substantial, reliable and cheap joint.
I will now describe the invention with reference to the accompanying drawings
in which :
Fig. 1 is an elevation of the runner tube.
Fig. 2 is an elevation of same with the annular hollow ring attached, part being
removed to show the aperture b, in the runner tube.
Fig. 3 is a plan of Fig. 2 showing the slots in the annular ring, and Fig. 34 is
a section of the ring.
Fig. 4 is a sectional elevation of the runner tube and of the annular ring with two
ribs in position.
Fig. 5 is a partial view of Fig. 4, on a larger scale.
Fig. 6 shows different forms of rib ends which can be employed.
Fig. 7 shows a modification of the invention as applied to a tent pole.
Referring to Figs. 1 to 6.
a, is the runner tube which is made in the ordinary way but is provided with a
suitable aperture b, and projecting bead c.
d, is a hollow annular ring fitted loose around the tube a, and upon the bead c, and
provided with radial slots e. When this ring is in position, the end of the tube a,
should project above the ring d, so that it can be expanded or turned over as shown
at f Fig. 5.
9.9, are the ribs formed with a head h, and with a thinner part gl.
The method of fixing the ribsis as follows:-
The ring d, is revolved until one of the slots e, is opposite the aperture b, in tube a,
when the thinner part gl, of a rib is passed through the slot e and the head h, is drawn
through the aperture b, and into the ring d. The ring is then revolved until all the
slots have passed in front of the eye and all the ribs are inserted; when it is so moved
that the aperture comes between two slots, and the projections, are made to engage
with some of the slots and thus prevent the ring turning accidentally.
In the arrangement shown in Fig. 7, which is specially designed for tent poles the
runner tube is dispensed with, the annular ring d, revolving loosely upon the pole k.
The ribs are inserted by bringing the slots in the hollow ring d, opposite a notch or
mortice 1, in the pole. When all the ribs are inserted the ring is fixed by screws or
nails m, as shown.
The mode of construction above specified is applicable both to the top fitting as well
as to that on the runner tube, and they can both be fixed in the same manner.
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:
1. In fittings for umbrellas, parasols, expanding tents and the like, the loose
annular slotted ring d, raised bead c, aperture b, and projections, in combination
with eycless ribs and stretcher bars formed with enlarged solid ends, as herein
described and set forth.
2. In fittings for umbrellas, parasols, expanding tents and the like, the special
manner of forming and supporting the loose annular slotted ring, and, of inserting
and connecting the enlarged ends of the ribs and stretcher bars thereto, without using
tie wires or eyes, and the mode of clamping the runner tube, or top tube, to said ring
so as to fasten the same, and secure the said ribs and stretcher bars therein, as herein
described and set forth.
