PROVISIONAL SPECIFICATION.
A Safety Apparatus for Use in Cleaning Windows and for other
purposes.
1, LEWIS ANIDJAH, of 24, Bridge Avenue, Hammersmith, in the County of
London, Gentleman, do hereby declare the nature of this invention to be as
follows: :-
My invention has for its chief object to provide means for obviating the liability.
of persons cleaning windows falling.
According to my invention I provide a framing adapted to be projected through
an open window and to carry a plank or platform for a person to stand upon and
wire-netting or the like for a protection around the platform.
In practice I find it advantageous to support my safety apparatus by means of
a bar, extending across the framing on the inner side and adapted to bear against
the inside of the window-frame, and two downwardly projecting pins or bars
entering eyes also secured inside the window-frame. The lower bars of the guard
framing are also shaped so as to fit over the bottom bar of the window-frame and
allow that part of the framing for supporting the plank or platform to rest upon
the window sill or come as close thereto as possible.
The sides of the framing to which the protecting netting is attached do not
extend through the window opening, so that the sashes may be raised and lowered
as required.
Although I have described my safety apparatus as designed for use by window
cleaners, it is obvious that it may also be used with advantage by glaziers, painters
and others, or it may be used as a nursery window guard.
Where my safety apparatus is intended for use in cleaning windows of different
widths I may provide it with two or more interchangeably supporting bars, pins
or the like being arranged to prevent the bar from slipping when the apparatus is
in use.

COMPLETE SPECIFICATION.
A Safety Apparatus for Use in Cleaning Windows and for other
purposes.
I, LEWIS ANIDJAH, of 24, Bridge Avenue, Hammersmith, in the County of
London, Gentleman, 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 :-
My invention has for its chief object to provide means for obviating the liability
of persons falling when cleaning windows.
According to my invention I provide a framing adapted to be projected through
an open window and to carry a plank or platform for a person to stand upon and
)´wire-netting or the like for a protection around the platform.

page_text: In practice I find it advantageous to support my safety, apparatus by means
of a bar, extending across the framing on the inner side and adapted to bear
against the inside of the window-frame.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
11
Figure 1 is a front elevation of my safety appliance :
Figure 2 is a side elevation representing the guard as applied to a window
opening; and,
Figure 3 is a plan of the same.
a is the bottom bar or frame of my guard having cross-bars a¹ and serving to
carry a platform, and 6 is the screen surrounding the said platform, which screen
as shewn is composed of upright bars c, c secured to the bar a and to a rail d,
braces e, e being arranged to give rigidity to the guard.
The bottom bar a is preferably bent at the side portions as shewn at ƒ Figure 2,
that is to say, so that it will rest on the window sill (indicated in the drawing by
the letter g) and on the lower bar of the window frame (indicated by the letter h).
the said side portions being also of such length that they will project on the inside
of the window frame as at i. To these inwardly projecting portions i, i are fixed
vertical bars j, j, tie-bars k, k being arranged between the said bars j, j and some of
the bars c, c of the screen 6 to steady the said bars j, j.
The lower ends of the bars j, j form abutments (which may enter eyes secured
to the window frame if desired) by means of which the position of the lower part
of the apparatus relatively with the window frame may be adjusted, and the upper
ends of the said bars are formed with eyes through which a rod 1, the length of
which is greater than the width of the window opening is passed. With this -
arrangement it will be obvious that when the guard is projected through an open
window the rod will rest against the window frame as shewn in Figures 2 and 3
and retain the guard in position. In order to relieve as much as possible any strain
upon the rod I sometimes form upon or attach to the tie-bars k, k arms m, m which
by bearing against the window frame will serve to support some of the strain.
The sides of the screen of the guard are formed as shewn in Figure 2 where the
rail d is represented as bent so as to leave a free space between itself and the
bars, for allowing the window sashes to be raised and lowered.
It will be understood that when the guard is in use planks or boards will be
arranged upon the frame a to form a platform, and that if desired wire-netting may
be placed around the screen to prevent anything from falling therethrough.
It will be obvious that the same guard may be used in windows of different
widths provided the rod is of the required length. In some cases several
interchangeable rods 1, 1 of different lengths may be employed, split or other pius
being passed through the rod adjacent to the eyes carrying it.
Although I have described my safety apparatus as designed for use by window
cleaners, it is obvious that it may also be used with advantage by glaziers, painters
and others, or it may be used as a nursery window-guard.
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 :-
1. In a safety apparatus for use in cleaning windows and for other purposes,
the combination of a platform carrying bar or frame, vertical bars secured to the
said bar or frame and carrying a rod designed to bear against the inside of the
window-frame, and a screen around the said platform frame, the said screen being
shaped at the sides so as to leave a space between itself and the said vertical bars,
all substantially as described.
2. In a safety apparatus of the kind referred to in the preceding claiming clause
for use in cleaning windows and for other purposes, a platform carrying frame
bent to fit over the window-frame and to rest on the window sill, substantially as
described.

page_text: 3. In a safety apparatus of the kind described for use in cleaning windows and
for other purposes, the arms m, m for affording additional support, substantially as
described.
