PROVISIONAL SPECIFICATION.
Improvements in and relating to Step Ladders.
I, PAUL MARCUS of 4 Donnerstrasse, Altona Ottensen, near Hamburg, in the
Empire of Germany, Manufacturer, do hereby declare the nature of this invention
to be as follows:
The object of this invention is a step ladder and the novelty consists in the
particular construction of the steps in combination with a special support for the
ladder when ready for use.
The steps have their ends fixed each in an angle iron adapted to turn at the
ends on pins in the two bars which form the ladder frame on each side. The pins
may be formed by wood screws screwed into the steps or by studs rivetted on the
angle irons.
The addition of the angle irons renders possible the use of thin boards as steps
because the latter are supported securely and evenly by the angle irons and breakage
is not likely to occur.
The support of the ladder consists of two struts joined one to the other which
can be turned round two of the step pins or round special studs fixed at the side
bars or frame of the ladder.
In order that on putting together of the ladder the struts do not project
sideways, rear bars of the ladder frame are made correspondingly thinner by the
amount of the thickness of the struts.
When the ladder is to be used the ends of the struts engage by means of
recesses in their ends with pins of the uppermost or other step.
Toggle jointed pairs of connecting bars join the struts to the rear side bars of
the ladder frame.

COMPLETE SPECIFICATION.
Improvements in and relating to Step Ladders.
I, PAUL MARCUS of Donnerstrasse 4, Altona-Ottensen, in the Empire of
Germany, Manufacturer, 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 a step ladder, the novelty of which consists of a
particular construction of the steps, in combination with a special support for the
ladder when ready for use.
In the annexed drawing
Fig. 1 shows the ladder folded together whilst Fig. 2 shows it half opened and
Fig. 3 completely opened.
Figs. 4 to 8 are details on a larger scale.
The steps s are fixed with their ends in augle-irons a which turn on or by the
pins in the bars b and b'.

page_text: The pins can be formed either by wood screws screwed into the steps, (Figs. 4
and 5) or by pins riveted into the angle irons a Figs. 6. 7 and 8.
The arrangement of the angle-iron allows of the use of thin boards as steps,
because the latter are supported securely by angle-irons and do not break away at
the ends.
The support of the ladder consists of two bars m connected together which turn
round one pair of the step-pins &¹ or special pins * on the bar bl.
In order that the supports do not project sidewards when the ladder is folded
together, the rods 6' are made thinner for an amount equal to the thickness of the
supports.
When the ladder is ready for use the supports m engage with their recessed ends
under the pins 3 of the bars b, as to be seen from Fig. 3.
In order to connect the support m securely with the ladder and to bring it
outwards when opening the ladder for instance into the position, Fig. 2 there are
conveniently arranged the connecting pieces a a¹ of which a is connected with one
of the steps and a' with the support.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
A step ladder the steps of which are fixed in angle-irons a
in the bars band and in which is arranged a support
and adapted to engage with its recessed end a second pin
.forth.
