Improvements in Ladders, Step Ladders, Tressels, and the like.
LAURANCE SEAGER Builder and Contractor London Road Milton, near
Sittingbourne in the County of Kent do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in ladders, step ladders, tressels & the
like, the object of the improvement being to make them more convenient, rigid and
safe in use also convertible for either purpose.
In carrying out my improvements I make two or more lengths of steps being
connected near the ends by suitable hinges or bolts. On one length of these steps
I provide two semi-circular metal rings with indents at convenient angles to admit
a bolt or spring catch & on the other length suitable staples or caps for these rings
to pass through having bolts or spring catches to engage in the indents of rings by
which means any angle may be obtained and held rigid.
. It will be obvious that more lengths may be added in the same manner thus when
straightened form a continuous ladder.

Improvements in Ladders, Step Ladders, Tressels, and the like.
LAURANCE SEAGER Builder and Contractor London Road Milton near
Sittingbourne in the County of Kent. I 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 improvements in ladders, step ladders tressels and the
like, the object of the improvements being to make them more convenient, rigid
and safe in use, also convertible for either purpose.
In carrying out my improvements I make two or more lengths of step being
connected near the ends by suitable hinges or bolts. On one length of these steps
I provide two semicircular metal rings with indents at convenient angles to admit
a bolt or spring catch and on the other length suitable staples or caps for these
rings to pass through having bolts or spring catches to engage in the indents of
rings by which means any angle may be obtained and held rigid.
It will be obvious that more lengths may be added in the same manner thus when
straightened form a continuous ladder.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing in which
Figure 1 is a side view shewing the general combination of the arrangement.
Figure 2 is a back elevation.

page_text: Figure 3 is a front elevation.
Figures 4, 5, 6 & 7 represent the bolt or spring catch.
Referring to Figure 1
A indicates the semicircular ring with indents a at intervals.
B is the strap hinge attached to one length and
C is the strap carrying a pin on which B rotates.
D is the bolt or spring catch that engages in indents a on the ring A.
E is one length on which is attached A and C.
F is another length on which is attached B and D.
It will therefore be readily understood that by withdrawing the bolt or spring
catch D the length F becomes free to be- moved in any position until the bolt or
spring catch D is allowed to become engaged in either of the indents a on the
semicircular ring A.
Although I have described my invention as applied to a ladder only it is to be
understood that it may also be used on tressels, rods, set squares and the like that
require to be adjusted at any angle and kept rigid.
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
In an improvement in hinging and holding in position one or more pieces of
material at any desired angle especially applicable to step ladders ladders tressels
and the like.
