PROVISIONAL SPECIFICATION.
An Extensible and Adjustable Scaffold for Building, House Painting,
and all other like purposes.
THOMAS HENRY WIMBUSH Number 2 Richmond Street East Street
Walworth London S.E. Clothier do hereby declare the nature of this invention to
be as follows:-
An extensible and adjustable scaffold sliding irons along the sides adjusted by
holes and pins supported by section ladder base, and scaffold brace and bracket
fastening hooks with bolts on the ends of all the above pieces which make a safe
fasteuing where all points come together, and bolts through the base of bottom of
scaffold, which makes it very safe and secure to the sections to it and all parts of
it, each section as irons in and over every slot with bolts through each and every
end, and an iron rod right through with nuts to fasten every joining section or part.
Quickly adjusted, and admirably adapted to all scaffolding purposes for either
inside or outside work. Can be adjusted to any desired height breadth or length from
one inch to a foot or as many as desired each & all parts made to fit each other, all
sections or parts to be made any desired length or size. Also the same are con-
vertible and folds by means of lock hinges into trestles also into step ladders of any
desired size by the means of sliding iron on the sides with holes and pins in the
sections to adjust from one inch to any desired length to make a short or long leg
for all stair work. The brace with two sliding hooks braces the two together under-
neath when used as a step ladder or trestle purposes. Flat steps are made
adjustable with fastening hooks and bolts so they can be removed from the round
when desired. Then the same can be used for a ladder any desired length, and the
same irons used with scaffold can be used to fasten them secure together, which
makes the strongest kind of long ladder.

THOMAS HENRY WIMBUSH, late of 2 Richmond Street, East Street Walworth
S.E., now of 305 Kings Road Chelsea S.W. Clothier 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 extensible, adjustable, and self-supporting scaffold for
builders, painters-house decorators-and for similar purposes.
The invention will effect a great saving of time and labour, over existing forms
of scaffolding by reason of its adaptability and portability, for outside or inside
work-doing away with much of the cumbersome plant required in the above
mentioned trades. The scaffold can be fixed to any desired height, length or breadth;
in a few minutes, and can as casily be taken down or removed, and conveyed any
distance in a light waggon-it will enable painters and decorators to work in shops,
or factories, without interfering with the trade or business carried on therein.
The scaffold is supported at each end of sectional ladders, resting on, and fixed in
a four or six feet timber base (or a spray foot flaring section) with adjustable
braces, fastened together with hooks and sockets fastened securely with sliding
01

page_text: bolts, with springs (or without) thus making it perfectly safe and secure each
section has irons in and over every slot and socket-with bolts-through each and
every end, with iron rod right through every joining section or part, with nuts to
fasten same.
Each and all parts, are made to fit each other.
The centre or cross sections, forming the scaffold platform-are fixed to the
upright sectional ladders, by means of hooks, with sliding bolts and spring, and are
adjustable by means of sliding irons--the aforesaid cross sections, are supported
also, and thus rendered rigid and secure, by stationary, and extensible braces-the
extension braces slide from end to end of platform.
The cross or platform sections, are adjustable from 8 feet to 15 feet-or any
desired length.
The sectional ladders-forming the ends, and support of scaffold platform are
made in four feet or six feet lengths fitting into sockets in the top end or side of
each ladder and can be thus used, as an extensible ladder to any desired height-
or any two sections can be used as a trestle or step ladder-by means of sliding
irons on the sides, with holes and pins in the sections, to adjust from one inch to
any desired length-thus also making a short or long leg for indoor stair work &c.
A bracket is also made to fit and fix on ladder sections, and two such brackets
can be used to form a small scaffold or platform by means of a plank from one to
the other.
The base for holding and supporting the sectional ladders and the whole of the
scaffold, will be supplied with small wheels (or without) to enable the scaffold to be
moved, when used for indoor work- -or for outside if desired.
The scaffold as a whole will be secured to the front of a building by means of
iron braces with an adjustable scaffold clasp; the brace being fastened to inside
of window of building, by a special plate and hook, adjustable also.
Any section or part can be made of any desired length or size.

Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be applied and performed, I declare
that what I claim is-
1. For an extensible, adjustable and self-supporting scaffold as a whole.
2. That the scaffold is extensible in itself.
3. That the scaffold is adjustable in itself.
4. That the scaffold is self-supporting.
5. That the scaffold is moveable without being taken down.
6. That the construction of the scaffold enables it to be put up for use in a few
minutes.
7. That the scaffold can be put up before a building, without the usual supports
placed in the walls.
8. For the wheels on base of scaffold to enable it to be moved from one position
to another, without being taken down.
9. For the sectional ladders, fitting into sockets to form an extensible ladder in
themselves.
10. That the sections, can be used separately, or together as ladders trestles or
step-ladders.
