Improvements in Ladders.
JAMES LINKLETER, Patentee and Manufacturer, Tyneside Works, Tynemouth,
Northumberland, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in ladders for ships and other purposes,
where ladders are wanted at different angles, and to stow away in a small space.
The steps always being level at whatever angle the ladder is placed. The object
being to lessen the number of parts, in present use for the above purpose, and so
simplify their construction and manufacture.
To this end I make each step and two bracket hinges out of one piece, as
follows, the steps are made by rolling long metallic slips which may be either
corrugated, perforated, plain, or chequered, with the edges turned down, when
these slips are cut at an angle in suitable lengths for the steps and turned down at
the ends, the longer part of the angle being lower forms the lower hinge which
lifts the back edge of the steps up level with the front edge of the step above,
when packing away, and so accomplishing the movements claimed in my former
patent.
With these steps either wood or metallic sides, and wood or metallic guidebars
to level steps, can be used, and the pins on which the steps work may be fixed
either in the sides, and work in the steps or vice versa.

in and by the following statement :-
My invention relates to improvements in ladders for ships and other purposes,
where ladders are wanted at different angles and to stow away in a small space, the
steps always being level at whatever angle the ladder is placed.
The object being to lessen the number of parts in present use for the above
purpose & so simplify their construction & manufacture.
To this end I make each step and the two bracket binges out of one piece, as follows,
the steps are made by rolling long metallic slips, which may be either corrugated,
perforated, plain or chequered or of any design, with the edges turned down, when
these slips are cut at an angle in suitable lengths for the steps and turned down at
each end, the longer part of the angle being lower forms the lower hinge which
lifts the back edge of the step, level with the front edge of the step above, when
packing away, and so accomplishing the movement claimed in our former Patent
A.D. 1884, 27 September No. 12,868. With these steps either wood or metallic

which the steps work may be fixed in the sides and work in the steps or vice versa.
The part of the step forming the bracket may be of various designs.
DESCRIPTION OF DRAWINGS.
Fig. 1. shews the metallic step cut at angles A. A. the length of step is between
dotted lines d. d. where the angles are turned down forming the brackets as shewn
in Fig. 2.
Fig. 2. shews end view of step & bracket, h. h. being holes for hinge pins, on
which the steps are levelled.
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.-
34.
Making self levelling ladders having the steps and brackets made out of one
piece.
