I, FREDERICK JAMES MOCKLER of The County of Gloucester Bank Ltd.
Wotton-under-Edge, Bank Manager, do hereby declare the nature of this invention
to be as follows :—
My improved folding ladder is formed of any required number of steps or links,
each step or tread being firmly connected to two side bars, so as to form a link
resembling the letter H. The ends of these are bent so as to form projecting
lugs in which the pivot pins or loose rivets are inserted. Looking at one of
these side bars from the side, one of these lugs projects to the right and the
other to the left, or alternate ways. The result of this is that when hung
against the vertical wall of a building, no matter which side of the ladder is
against the wall, the treads are kept out from the wall by a distance regulated by
the length of the lug.
The lugs also facilitate the folding of the ladder by allowing each link to fold
over the next.
The alternate links are a little wider than the intermediate links to which they
are coupled so as to allow them to fold conveniently.
At the top of the ladder a short link is formed with eyes or loops for attaching
a rope or chain.

COMPLETE SPECIFICATION.
A Metal Folding Ladder.
1, FREDERICK JAMES MOCKLER of The County of Gloucester Bank,
Wotton-under-Edge Gloucestershire, Bank Manager, 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 is designed to provide a portable folding ladder, available as a
fire-escape and for other purposes.
It consists of any required number of rungs or steps, each one of which is firmly
connerted to two side bars so as to form a link resembling in front elevation the
capital letter H.
The ends of these side bars are bent so as to present projecting lugs in which the
pivot pins or loose rivets are inserted.
Regarded from the side of the link, one of these lugs projects to the right, and
the other to the left or alternate ways.
The result of this is that when hung against a vertical wall no matter which side
of the ladder is against the building, the rungs or treads are kept out from the wall
by a distance regulated by the length of the lug. This enables anyone descending
or ascending to grasp the rungs and also to find a safe foothold no matter how
burriedly the ladder may be placed in position.
The lugs also facilitate the folding of the ladder by allowing each link to fold
over the next.

page_text: I will now describe the invention with reference to the accompanying drawings
in which
Fig. 1 shows a front view of my ladder open ready for use.
Fig. 2 shows a side view of the same.
Fig. 3 shows a side view of the ladder folded.
a, is the rung or tread which is rivetted to the side bars at e. It may be round,
square, or of any preferred section. Or it may be formed of rod or tube flattened
in the centre but left round at the ends so as to be easily grasped.
b, is the side-bar which is pivotted at c. b', is the projecting lug.
It will be observed that the alternate links of the ladder are a little wider than
the intermediate links to which they are coupled, which allows them to fold
conveniently.
At the top of the ladder a short link f, may be formed with loops f¹, or eyes, for
attaching to a rope, chain or hook. Or eyes or loops 9, can be formed on the
ordinary link if preferred, and may be placed at both ends of the ladder if
desired.
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 a folding ladder the special form of side-bar b, with lugs 6', at each end, as
herein described and set forth.
2. In a folding ladder the combination of the side-bars b, rungs a, and joints c,
as herein described and set forth.
