PROVISIONAL SPECIFICATION.
An Improved Portable Collapsible Seat, Occasional Table,
or the like.
I, JOHN THOMAS, of Ladbrook Grove, in the County of London, Engineer, do
hereby declare the nature of the said invention to be as follows:-
:-
This invention relates to an improved portable collapsible seat, camp-stool,
occasional table or similar article of utility, hereinafter (for convenience of
description) referred to as a seat, and which is adapted to close up for insertion
into a tubular walking stick, fishing rod or other enclosing case.
The improved seat is constructed with a central stem, with which are structurally
combined a supporting extensible and collapsible tripod and a supported extensible
and collapsible seat, each of such parts being of the construction and the several
parts being adapted to co-operate as hereinafter described.
The central stem is made of a tubular formation; and into its lower end there is
inserted and secured by brazing or in any other suitable manner a shouldered
three-armed radiating piece, to the projecting parts of which the top ends of the
tripod-legs are respectively pivoted. Each leg of the tripod is made of an inverted
trougl-shape, and at its top end is adapted to embrace its arm of the said
radiating piece, to which it is secured by a rivet, eyelet or the like passing through
both sides of the leg and the intervening arm. At such end, the back of each leg
is cut out or otherwise formed in such a manner that, when the legs are opened out
to their desired extended positions, each leg will abut against and be arrested by
the arm by which it is supported. The adjacent or meeting parts of the several
legs of the tripod are also respectively so shaped that, when the legs are opened
out as aforesaid, they will abut against and arrest each other in the desired
extended position. The bottom ends of the tripod-legs are all linked or connected
to a common ring, equidistant from the several legs, by rods which (also, may be
trough-shaped, and) at their inner ends are flattened, pierced and threaded on said
ring, and at their outer ends are respectively rivetted, eyeletted or otherwise
equivalently pivotally connected to and between the sides of their respective
tripod-legs, and are, moreover, respectively, at such part, so shaped at their under
parts as to abut against and be arrested by the inner side of the back of the legs
when the legs are distended. Such formation of the tripod legs renders them rigid
when distended.
To an upper part of the central stem are brazed or otherwise suitably secured.
two parallel flanges which are notched across at equidistant intervals, the flanges
being adapted to support a wire or ring between them and on which a series of
radiating stretchers are centred, and the notches being adapted to permit of such
stretchers having a pivotal movement about said wire or ring as a centre.
A.bove such notched flanges, the stem is adapted to guide or support a tube (or
it may be a rod) depending from the centre of the seat, when in its usable position,
and to locate said centre in the desired relation to that of the supporting stem,
which latter is (or may be) formed with an abutment serving to support and arrest
said depending tube in the desired position. The top of such tube constituting the
centre of the seat, is, in like manner as aforesaid, formed with parallel notched.
flanges serving to support a wire or ring on which a series of radiating bearers are.
centred, in like manner as herein before described with reference to the series of
:

page_text: radiating stretchers. All said radiating stretchers and bearers are of a trough-
shaped formation, the outer ends of the stretchers being inserted and rivetted
between the sides of the bearers, the outer ends of which latter are flattened in a
horizontal plane and are pierced with holes to which a flexible rim or border is
sewn or otherwise attached in such a manner as to serve to keep the connected
stretchers and bearers equidistant when in use. When the seat is in use, the
depending tube thereof engages with the top part of the said central stem, resting
on the said abutment, and serves to keep the seat distended and rigid. When it is
desired to collapse the seat, its depending tube is disconnected from said central
stem in an axial direction, which causes all the stretchers and bearers to collapse
towards the centre until they are in practical alignment. The tripod-legs are also
adapted to close together, the distending rods thereof closing into the trough-
shaped legs, so that the whole device can then be inserted end wise into a tubular
walking stick, fishing rod or other couvenient tubular case.
When combining the device with a tubular walking stick adapted to contain
the same, the tripod may be separable from the stem, and may be adapted to fit
into a notched tube inserted into the top end of the stick, which may be adapted
with a removable cap or cover in like manner as described in the specification of
another application for patent filed by me of even date herewith No. 13379 of 1895;
and the stem of the seat may be adapted to fit into a tube inserted into the bottom
end of the stick, which end, at other times, may be closed by a removable ferrule
in like manner as described in the specification of said application for patent.
A flexible cover of canvas or other material may be detachably or permanently
applied to the bearers of the seat-frame.
By the aforesaid improved construction, I produce an improved device of the
kind of a much simpler construction than existing devices of the kind, and of a
less weight (which is a great desideratum) and at a less cost.

An Improved Portable Collapsible Seat, Occasional Table,
or the like.
I, JOHN THOMAS, of Ladbrook Grove, in the County of London, Engineer, 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 an improved portable collapsible seat, camp stool,
occasional table or similar article of utility, hereinafter, for brevity, referred to as
a "seat," and which is adapted to close up for insertion into a tubular walking
stick, fishing rod or other enclosing case.
On the accompanying drawings:
Fig. 1, represents an elevation of the seat extended, ready for use.
Fig. 2, represents the same collapsed, for insertion into its tubular case, not
shown.
Fig. 3, is a plan of the top.
Fig. 4, is a sectional plan on 1,-1, Fig. 1. and
.Fig. 5, is a sectional elevation, in full size, showing the parts in detail.
The device is constructed with a central tubular sten: a, ax, with the lower and
upper parts of which are respectively and structurally combined a supporting
extensible and collapsible tripod b, and a supported extensible and collapsible seat c,
as hereinafter described. The stem parts a, ax, are connected by a tube a 3, which

page_text: is formed with a flange a 4, and screws into the stem part a. and permits of
the part a*, turning about it. The stem parts a, a*, may, however, be made
in one:
The tripod legs are of an inverted trough-shape (Fig. 4) and at their top ends 62,
are pivotted by pins a 2, into notches a 1, formed in the stem part a, and are so shaped
(Fig. 5) that, when the legs are extended, each such leg-end will abut against and be
arrested by the back of its notch a 1. Their bottom ends are linked to a central
ring 63, by trough-shaped stretchers 64, which, at their inner ends 65, are
pivotally connected to the ring 63, and, at their outer ends b 6, are pivotally
connected to and between the sides of the tripod legs, and are so shaped at their
under parts 67, as, when the tripod is distended, to abut against and be arrested by.
the backs of the legs. This peculiar construction of the tripod renders it very
rigid when distended.
The stem part a*, is formed with parallel flanges a 5, which are notched across,
as at a 6, at equidistant intervals, the flanges serving to support a ring a 7, on which
a series of radiating stretchers c I, are centred, and the notches locating such
stretchers laterally and permitting of their having a pivotal movement about said
ring.
The stem part a, serves as a guide to a rod d, which extends from below the
ring 63, upwards through the stem parts a, a*, and the tube a 3, and is connected
to the centre of the seat, which also is formed with notched flanges c 2, serving to
support a ring c 3, on which a series of radiating bearers c4, are centred, in like
manner as described relatively to the stretchers c 1.
All said stretchers and bearers are trough-shaped, the outer ends of the stretchers
being inserted and rivetted at c 5, between the sides of the bearers, the outer ends
of which latter are flattened horizontally and pierced with holes c 6, to which a
flexible rim or border c 7, is sewn or otherwise attached in such a manner as to keep
the stretchers and bearers equidistant when in use, vide Fig. 3.
When the seat is in use, its centre part rests on the tube a 3, and an enlarged
part d 2, of the rod d, enters into the tube end and serves to locate the seat in the
desired relation to the support ing stem and to keep the seat distended and rigid.
When it is desired to collapse the seat, the centre of the seat is pulled in an axial
direction away from the stem tube, which causes the stretchers and bearers to
collapse towards the tube until they are in practical alignment, vide Fig. 2. The
tripod being also adapted to collapse, the stretchers thereof close into the troughed
legs, and so enable the whole device to be inserted into a tubular walking stick,
fishing rod or other convenient tubular case of very small diameter.
A flexible cover of canvas or other material may be applied to the bearers when
the seat is in use.
By the above described improvements, I produced an improved device of a much
simpler construction than existing devices of the kind, and of a much less weight,
which is a great desideratum, and at a less cost.
When combining the device with a tubular walking stick adapted to contain the
same, the tripod stem part may be made separable from the seat stem part, and
may be adapted to fit into one end of the stick, which end, at other times, may be
closed by a handle in like manner as described in the specification filed by me in
pursuance of my application for Patent, No. 13379, of 1895, and the seat stem part
may be adapted to fit into the other end of the stick, which end, at other times,
may be closed by a removable ferrule as described in said specification.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
In portable collapsible seats, camp stools, occasional tables and similar articles of
utility:
:-
1. In combination, a central tubular stem, an extensible and collapsible tripod,

page_text: and an extensible and collapsible seat or top, respectively constructed and adapted
to co-operate as described.
2. A central tubular stem made in upper and lower parts connected by a flanged
tube screwing into one part and permitting of the other part turning about it, the
one part being structurally combined with an extensible and collapsible seat or top,
and the other part being combined with an extensible and collapsible tripod, and
adapted to guide a rod depending from the seat, and which, in turn, serves to
steady the tripod, as described.
3. An extensible and collapsible tripod constructed and adapted as described.
4. An extensible and collapsible seat or table top constructed and adapted
as described.
