New or Improved Apparatus capable of being used as a Ladder, an
Extensible Ladder, or a Pair of Steps.
I, ANDREW BARR, of Camphill Cottage, Bothwell, Joiner, do hereby declare the
nature of this invention to be as follows:-
This invention relates to an apparatus which can, as desired, be used either
as a ladder, an extended ladder, or a pair of steps.
In constructing the ladder I make it in two parts one part being provided with
either steps or rungs and having at its upper end a guide roller or guide wheels
or their equivalent and also recesses or slots. The other part of the ladder which
has preferably rungs on it and not steps has at its upper end guide wheels or a
guide roller which run or runs against the wall or building and also a cross bar
preferably made of metal the ends of which are capable of catching in the
recesses or slots of the other part. The lower end of the second part is provided
with catches to grip on the rungs of the first part.
The ladder (or first part) can be extended by merely pushing up the second
part on it.
When it is desired to use the apparatus as a pair of steps the second part is
pulled out until its cross bar rests in the recesses of the first part. The steps
can be held in position when open by means of a hooked bar or catch having a
screw adjustment.
If desired instead of using a guide roller for guiding the movements of the
second part it may be guided by means of overhung wheels or catches fitted to the
first part. Or such overhung wheels can be used in conjunction with the guide
If desired the sides of the ladder may be strengthened by means of metal wires

or rods.
New or Improved Apparatus capable of being used as a Ladder, an
Extensible Ladder, or a Pair of Steps.
I, ANDREW BARR, of Camphill Cottage, Bothwell, 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 invention relates to an apparatus which can, as desired, be used either
as a ladder, an extended ladder, or a pair of steps.

page_text: And in order that my said invention may be properly understood I have here-
unto appended an explanatory sheet of drawings, whereon,
Fig. 1 is a view of the apparatus extended, Fig. 2 is a view of the apparatus
opened out like a pair of steps, Fig. 3 is a view of the apparatus folded up and
Figs. 4 and 5 are enlarged detail views.
In constructing the apparatus I make it in two parts a, b, the one part being
provided with either steps or rungs 6 and having at its upper end, a guide roller
or guide wheels or equivalent c and also slightly curved recesses or slots done
at each side. The roller c is carried in the eyes of metal straps c¹ secured to the
top of the part b. The other part a of the apparatus, which has, preferably,
rungs on it and not steps, has, at its upper end, wheels or a guide roller e which
run or runs against the wall or building, in the manner shown at Fig. 1, and
also a cross bar f, preferably made of metal, the ends of which are capable of
catching in the recesses or slots d of the part b. The lower end of the part a
is provided with two wooden or other catches g to grip on the rungs of the part b.
The apparatus can be extended, as shown at Fig. 1, by merely pushing up the
part a upon the part 6 and allowing the catches y to grip against the rungs in
the manner shown.
When it is desired to use the apparatus as a pair of steps the part a is pulled
out until its cross bar f rests in the recesses d of the part b.
If desired the sides of the ladder may be strengthened by means of metal wires
or rods.
The apparatus may, if necessary, be altered in the details of construction.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
consider novel and desire to claim is:-
The construction or general arrangement and combination of parts of the
apparatus substantially as herein before described and shown on the drawings
annexed.
Dated this 28th day of July 1897.
