Improvements in Umbrellas.
1 ZEBULON WIRT of 49 Lincoln's Inn Fields London W.C Salesman do hereby
declare the nature of this invention and in what maune the same is to bo
performed, to be particularly described and ascertamed in and by the following
statement:
My invention has for its object the construction of an umbrella capable of
folding upon itself, thus reducing the length of the frame by one half, when in
closed or folded position, to be detachable from stick, and suitable for use with any
stick or walking-stick of a given thickness, jointed or otherwise, having a smooth
outer surface, and which together with the stick if it be jointed, can be consemently
carried in the pocket, bag or other receptacle.
The frame in my improvement consists of ribs stays and braces of metal or other
suitable material preferably U shaped in cross section shown as closed in Figure 1
of drawings hereto attached and made a part of this Specification. This frame is
attached to a main tube c Figure 2 and which is tapering, and at the smaller end of
which is a grooved collar e' containing notches o recesses into which the inner ends
of the ribs a are pivoted in a similar manner to the ordinary umbrella. This
collar c is theaded above and a ring c screwed down on it for clamping the cloth
of the cover Below collar el near the end of the main tube c is the fastening cd
which attaches the frame to the stick A and is preferably a spring catch attached
to one side of the tube c by a rivet, and which extends around the tube c terminating
in a button which extends through the tube and into the stick A. At the
larger end of the main tube c are two lugs or catches c which engage with the
latches when open
g
On the main tube e below the collar c is placed a slotted tube or slide see
Figure 3 at the upper end of which 18 a grooved collar d' containing notches or
recesses corresponding to those in colla c' described above, and into which are
pivoted the inner ends of the stays b in a like manner. The slots & are opposite
each other and are formed so as to permit the slide d sliding down on the main
tube c, so that the ends may project below the two lugs, c³, and engage the slide h
before the latches g engage with lugs c³.
Figure 4 represents a runner or slide independent of the main tube c which works
on the stick A below the main tube c and which is free to move up and down when
the frame is being raised or lowered. It consists of a short tube which contains
a grooved collar in which are notches or recesses corresponding and similar to those
described on collars of main tube c and of slide d. It also contains lugs or
projectors into which are pivoted two spring latches g which engage with catch c³
on main tube c.
The ribs are divided into two parts of equal length a and a', a is pivoted to the
collar c and is attached to a' by a double binge joint e Figure 5 which allows the
rib to fold down upon itself. At a a main brace a' is attached at its upper and
outer end to a and at its lower and uner end is pivoted into the lugs or projections
of the collar on the sides similar to the ordinary umbrella.
The stays are divided into two parts of unequal length and 6' which are
connected by a wide binge joint Figure 6. This stay is pivoted at its inner end
into the recesses of the collar d' on the main tube slide d the outer end of this
stay b 18 pivoted to the outer end of the main riba at a b.
The effect of this combination is that when the lower slide (Figure 4) is pressed
upwards the main braces a press the upper half of the ribs a outward and upward,
the slide d is lowered and the jointed stays && permit the outer half of main ribs a¹

page_text: to fall and theu to draw them down and as soon as the slides h Figure 4 and d
Figure 3 come together they form a binced truss, and by a slight further pressure
the latches q engage lugs and the umbrella is then fully extended in the open
position as shown at Figure 1 Sheet 2.
In order to close the umbrella the latches are released by pressure of the levers y
and this permits the parts to be returned to the closed position.
Having now particularly described and ascertained the nature of the said
invention and in what manue the same is to be performed I declare that what I
claim 18;
1. An umbrella constructed to fold upon itself, the main tube c formed with a
grooved collare at its upper end, and at its lower end two lugs or catches c³ with
means for detachment as and for the purpose herein described.
2. An umbrella constructed to fold upon itself, provided with a slotted tube or
slided working upon the main tube c as and for the purpose herein described
3. In an umbella constructed to fold upon itself, providing a runner or sliding
piece independent of the main tube c, with spring latches g as and for the purpose
herein described.
h
4. Au umbrella constructed to fold upon itself, the combination of jointed
ribs a al a², stays bb', and braces a with main tube c, slide d, and sliding piece h,
thus reducing the length when closed, all as herein described and for the purpose
specified.
5. An umbrella detachable from the stick and suitable for use with any stick or
walking-stick of a given thickness.
