ALFRED EDGAR KITSON Plumber's Manager 14, Dawson Street Middletown Skipton
in Craven do hereby declare the nature of this invention to be as follows:-
This invention has for its object the better construction of Step Ladders and Trussels
by furnishing them with an Improved Regulating Locking Stay and moveable
Steadying Pillar. And in order that this Invention may be fully understood I herein
give reference to the accompanying 2 Sheets of Drawings marked with Figures and
Letters of reference, the same Letters referring to the same parts in the various views
or Figures as follows-
The principal features of the Apparatus consists of a flat metal Plate (A) Fig. 1.
circular in form, toothed or cogged on the top side of its outer edge, in proportion to
about th of its circumference in order to receive the Drop Bolt or Catch (B) Fig. 1.
into one of the cogs of Plate (A) ilus locking it in the required position as shewn
Fig. 1. a Arm or Lever (C) projects from one side of Plate (A) and is connected to
another Arm and Joint (D) by means of a middle joint (E) Fig. 1. The Plate (A)
works on a
capped Stud (G) rivited on the Back Plate (H) Fig. 1. Drop Bolt (B)
is also rivited in position on Back plate (H) and the Back plate referred to is screwed
on one side of Step Ladders or Trussels in position as shewn in Fig: 2.
In working the Apparatus as shewn in Fig. 2. the drop Bolt (B) is raised up, the
legs of Step Ladder is extended to the required distance the Bolt (B) is lowered into
one of the cogs on plate (A) and thus secures the Stay.
The steadying pillar (J) when not in use is fixed on one side of Step Ladder-by
means of the bottom portion entering a Cup or Socket (K) and is secured near the top
by means of a Staple and Pin (L) Fig. 3. When required for use the piller is pushed
up side of Lalder, through the Staple, until near the top-the bottom of Pillar is
placed in the Cup or Socket (M) and fastened by the pin as shewn Fig. 3.
Having thus described the nature of this my said Invention, and shewn by drawings,
how the same is to be, or may be performed or carried into practice-and I claim as
new in the said invention parts as follows Cogged Plate (A) Drop Bolt or Catch (B)
Projecting Arm (C) working in connection with Back Plate (H). Pillar (J) Cup or
Sockets (K) and (M) as shewn in Figures 1. 2 and 3.

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 has for its object the better construction of Step Ladders and
Trussels, by furnishing them with an Improved Regulating and Locking Stay, and
moveable Steadying Pillar. And in order that this Invention may be fully understood,
I herein give reference to the accompanying Sheet of Drawings together with
those (2) left with the Provisional Specification" each marked with Figures and
Letters of reference, the same Letters referring to the same parts, in the various views
or figures as follows--
The principal features of the Apparatus consists of a flat metal plate (A) Fig. 1
circular in form, toothed or cogged on the top side of its outer edge in proportion to
about one 4th of its circumference, in order to receive the Drop Bolt or Catch (B)
into one of the cogs of Plate (A) thus locking it in the required position as shewn
Figs. 1 and 4 A arm or lever (C) projects from one side of Plate (A) and is con-
nected to another Arm and Joint (D) by means of a middle Joint (E) Fig. 1. The
plate (A) works on a capped Stud (G) rivited on the Back Plate (H). The Drop
Bolt or Catch (B) is also rivited in position on the Back plate (H) and the Back
plate referred to, is screwed onto one side of Step Ladders or Trussels, in position as
shewn in Figs. 2 and 4.
In working the Apparatus as shewn in Figs. 2 and 4. The drop Bolt or Catch (B)
is raised up, the legs of the Step Ladder is extended to the required distance the drop
Bolt or Catch (B) is lowered into one of the Cogs on Plate (A) and thus secures the
Stay in position.
The Steadying Pillar (J) when not in use is fixed on one side of the Step Ladder
by means of the bottom portion entering a Cup or Socket (K) and is secured near the
top of Ladder by means of a staple and pin (L) as shown Figure 3, and when required
for use the pillar is pushed up the side of Ladder through the Staple untill near the
top the Bottom part of Pillar is placed in the Cup or Socket (M) and fastened
in position by the pin and chain as shewn Fig. 3.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed-I declare that what I claim is―
No.
1-Toothed or Cogged Plate (A).
2-Drop Bolt or Catch (B).
3-Projecting Arm or Lever (C).
4-Moveable Pillar (J).
5-Staple and Pin (L).
