PROVISIONAL SPECIFICATION.
Improvements in Step-ladders.
I, ANDREW BARR, of Camphill Cottage, Bothwell, Carpenter, do hereby
declare the nature of this invention to be as follows:-
This invention relates to step-ladders and it has for its object to cheapen and
improve their construction.
The step-ladder as made in accordance with my invention consists of the usual
step-part and supporting-part which make, when extended, an A shape. The parts
are hinged together at their upper ends by means of a metal bar or rod, which is
fitted in the step-part and passes through eyes or holes in metal plates or pieces
secured to the supporting-part. To prevent the steps, when expanded, opening too
far, metal catches are fitted on the under side of the top step or platform. The
arrangement of the hinge is such that the supporting part can be either folded to
the inside or to the outside of the other part.
With this construction of ladder, no ropes or catches are required to keep it in
its extended position.
The catches are, preferably, bent pieces of metal.

COMPLETE SPECIFICATION.
Improvements in Step-ladders.
I, ANDREW BARR, of Camphill Cottage, Bothwell, Carpenter, 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 step-ladders and it has for its object to cheapen and
improve their construction.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon,
Fig. 1 is a side elevation, partly in section, of the step-ladder showing it open.
Fig. 2 is a part back view of the ladder when closed.
Fig. 3 is a part front view of the ladder when closed.
Fig. 4 is a plan view of a rest for paint pots etc.
Referring to the drawings whereon the same reference letters wherever repeated
indicate the same parts.
a is the support of the ladder and b the step part. As will be seen the parts a, b,
are hinged together at their upper ends by means of a metal bar c which passes
through holes in the sides of the part b, being secured in position by a nut c¹ and
also through eyes made in metal plates or brackets d, d' secured to the sides of the
part a. The part a may, as shown, be fitted in the inside of the part b or be fitted
on the outside of said part.
The side bars of the part a are, as shown at Fig. 1, cut at an angle at their upper
ends at e and when the ladder is extended said angled ends e catch against the cross
bar or board m at the underside of the top board f of the ladder which is thereby
prevented from being opened out too far. This arrangement obviates the use of
cross bars or ropes etc., as usual.
If desired instead of the board m, small metal catches may be fitted on the

page_text: underside of the top board f for the purpose of keeping the ladder in its proper
extended position.
Fitted on to the part a is a rest g for paint pots and the like, which consists of
a frame with cross pieces. The rest is hinged or turns on the pivots h which are
screwed into the sides of the part a. The ends of the rest, when it is in the
horizontal position, catch against the underside of the step i and also bear against
the cross piece k. The rest, when in the position shown at Fig. 1, also serves to
keep the ladder in the extended position. 7 is a support for the rest.
The improved ladder can be made very cheaply as it is simple in construction.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :-
A step-ladder constructed substantially as herein before described with reference
to the drawings annexed.
Dated this 15th day of November 1893.
