COMPLETE SPECIFICATION.
Improved Portable Outside Window Cleaning Chair.
I, DUNCAN WILLIAM CARTER, formerly of 74, South Castle Street, Liverpool,
in the County of Lancaster, but at present of Exchange Station Buildings,
Liverpool, aforesaid, Agent, 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 :-
The article according to this invention is somewhat similar in general appearance
and form to the back and seat of an ordinary chair, and is of strong and compact
construction, it being made of wood or any other suitable material or materials.
It is of convenient form, and safely secured to the window or window sill by means
of staples secured to the window frame or sill, the chair being attached to said
staples by means of hasps and pins or equivalent means. It may be used in the
cleaning of the outside of windows or for any other purpose of a like nature.
In the drawings which serve to illustrate my invention,
Figure 1 is a front elevation of a window cleaning chair according to this
invention.
Figure 2 is a plan of same shewn applied or fixed outside a window, Figure 3 is
an end view, and Figure 4 is an elevation shewing the seat or chair in its folded
condition.
Referring now to the drawings, the chair there shewn is of the folding type, and
consists of a back a, a seat & fixed to the back a by hinges c, and side frames d on
the outer bar of which the outer end of the seat or corner brackets b¹ of said seat
rest, and to which they are clamped by the thumb screws e. f are the hasps, which
are fixed on the seat b and have pins or hooks f' mounted thereon; whilst are
the staples secured by screws h' or other means to the silli of the window, said
staples passing through the slots or gaps in the hasps when the chair is fitted, the
hooks or pins f passing through the said staples above the hasps, and so locking
the chair onto the window sill. The side frames d are hinged at three parts j k and l,
so as to allow them to be folded against the back of the seat. m is an angle bar
hinged at n to the side frames d, its opposite end passing through the lower
horizontal frame member d', and being secured when desired therein by the
thumb-screw o. This angle bar m forms feet on which the chair rests on the outer
part p of the window sill, as shewn in Figure 3; and according to the inclination
of this outer part of the sill, this angle bar in is moved or adjusted about its joint n
and locked by the thumb set screws o.

page_text: Staples will be permanently fitted (or temporarily if desired) by their base
plates to the sills of the house or other building, and thus a single chair may
be used for any number of windows; all that is required to be done being merely
to slip the hasps f over the staples and locking said hasps therein or thereon by
passing the hooks through said staples. When its use is completed in con-
nection with one window it is taken away by simply unlocking or withdrawing the
.hooks, and lifting it off the staples.
To fold the chair, the thumb screws e are slacked and the seat b is moved up
about its hinges c into the vertical position shewn in Figure 4, when the corner
brackets 6 will have passed the upper joints of the side frames d. Then the
said side frames d can be folded inwards about the joints j k and as shewn in
Figure 4, and there fastened by a catch or button r, and the thumb screws e may
be again fastened.
In some cases the side frames may be non-folding, in which cases the
joints j, k and would be dispensed with; and other joints in the chair might in
such cases be dispensed with.
The parts of the chair may be made in different kinds of material accordingly as
they may be suitable or as may be desired.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. A window chair for use in cleaning the outside of windows, or similar
purposes, adapted to rest upon the window sill, and to be secured by hasps and
staples, or equivalent means; substantially as herein set forth.
2. The window chair for use in cleaning the outside of windows, or similar
purposes, adapted to be connected or fixed in position by the hasps and staples and
also adapted to fold up as set forth and shewn in the example illustrated in the
drawing.
