I, THOMAS HENRY SULLIVAN, of 15, Frankfort Avenue, Rathgar, Dublin, Soldier,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of ladders, and has
for its object to provide an arrangement which can be more conveniently carried
about and stored than is the case with the ordinary ladder.
In carrying out my invention I propose to form the ladder in sections, each
section containing a small number of rungs. These sections are hinged together
the hinges being placed alternately at back and front, so that the sections can be
collapsed against one another. To secure the latter in extended position, clips
are employed at each joint, consisting of a spring catch. A suitable socket is
placed at one side of the joint and to the adjacent end of the next section a
spring is fitted which can engage in the said socket, the catch being released by a
simple pressure or by any simple action.

to be performed to be particularly described and ascertained in and by the
following statement:-

In order that the invention may be more clearly understood reference is had to
[Pic 8d1

page_text: the accompanying sheet of drawings in which Fig. 1 shows a part of my ladder
extended, Fig. 2 is a view at right angles and Fig. 3 shows it collapsed.
As shown the ladder is made of separate sections A the side bars being
divided into a number of lengths preferably equal. These are provided with the
hinges B which are placed at opposite sides at the different ends of each section.
The sections can thus collapse together in the manner shown in Fig. 3 the side
bars folding up against each other. These are held in extended position by the
clips C which are fitted at each joint and at one or both sides. These clips in
the arangement shown consist of a socket on one section with a projecting spring
on the next extending into the socket.
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) An improved ladder formed in a series of sections each section connected to
the next by a hinge allowing the ladder to collapse substantially as described
and for the purposes specified.
(2) The improved ladder formed from sections the sections connected together
by hinges placed alternately at opposite sides and held in extended position by
spring catches substantially as described and shown in the accompanying draw-
ings and for the purposes specified.
