page_text: I, HENRY OVENDEN, of Crown Cottage, Varney Street, Calverley Road, Tunbridge
Wells, in the County of Kent, Carpenter and Joiner, do hereby declare the nature of
this invention to be as follows:-
This is a step-ladder furnished with back supports connected to its sides by links
or stay-rods (which limit the opening of the ladder); at the top of these supports,
two almost parallel bars are attached, one on the inside and one on the outside, the
inside bar working in a groove, cut out so as to admit of its passing up and down,
the steps can be made with either skeleton or solid sides, and the advantage claimed
for them is, remarkable stability and strength, owing to the use of the bars above
mentioned, by which also hinges are entirley dispensed with.

I, HENRY OVENDEN, of Crown Cottage, Varney Street, Calverley Road, Tunbridge
Wells, in the County of Kent, Carpenter and Joiner, 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 is a step ladder furnished with back supports connected to its sides by link
or stay-rods which limit the opening of the ladder.
At the top of those supports, two almost parallel bars are attached, one on the
inside, and the other on the outside, the inside bar working in a groove slot or
slots, out so as to admit of its passing up and down. This step ladder can be made
with either skeleton or solid sides
In order that my invention may be clearly understood, I append drawings in
which

a is a bar fixed on the inside of the back supports at or near the top and by the
action of opening the step ladder slides in the grooves slot or slots g to the top
and back to the bottom of the grooves slot or slots when the step ladder is closed.

and slides with it on the outside of the grooves slot or slots g by the action of
opening and shutting the step ladder.

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. The heroin described step ladder substantially as described and shewn.
2. In a step ladder having a groove slot in or through the top of ench side close
under the top step substantially as shewn and described.
3. A step ladder provided with two parallel bars fixed on the back supports at or
near the top, one bar on the inside and one bar on the outside of the back supports
the tops of which press hard against the under side of the top step when the step
ladder is in use, substantially as described and shewn.
4-In a step ladder having grooves a slot or slots and parallel bars, it is provided
that the bars slide (one inside and one outside) the grooves slot or slots on the action
of opening and shutting the step ladder substantially as shewn and described.
5-A step ladder provided with a link or stay rod pivotted on each side to limit
the opening of same, substantially as described and shown.
