hereby declare the nature of this invention to be as follows:-
It consists of a revolving projection to be permanently affixed to the upper story
windows of any building, and attached thereto in such a manner as to be available for
immediate use in case of fire, and comprises an iron rectangular frame which is
supported by means of iron sockets fixed to stone or other blocks, firmly embedded in
the wall; the top of the frame being made to reach to the sill of the window of the
story above that against which the base of the projection is resting.
By its extension a ladder attached thereto of rope, chain, or twisted galvanized wire,
with wood or other staves is conveyed through the window the ladder being suspended
from a rack concealed in a wood case within the window back and so arranged as to be
paid out or drawn up at pleasure.
When intended to be used for descent from the third floor, an additional length of
ladder would be made to depend from the projector so as to meet the required distance.
The projector will also suspend a light cradle depending therefrom, the cradle being
made to descend with the Projector or to slide up and down by means of ropes
pullies & other necessary appliances, so that an invalid or child may be let down
with safety.
The Cradle and Ladder to be used either conjointly or separately, and the Cradle
when required on the same projector, can be made to serve as a receptacle for the
ladder when not in use. Those descending by the Cradle are kept by the Projector
at a distance from the lower windows, and out of reach of flames which might issue
therefrom, and it is especially intended to be of use where a fire may be spreading
rapidly.

I JOHN IZARD of 145 Brecknock Road St. John's College Park London Accountant
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:
It consists of a revolving projector to be permanently affixed to the upper story
windows of any Building, and attached thereto in such a manner as to be available for
immediate use in case of fire, and comprises an iron rectangular frame, which is
supported by means of iron sockets fixed to stone or other blocks, firmly embedded in.
the wall; the top of the frame being made to reach to the sill of the window of the
story above that against which the base of the projector is resting.-By its extension
a ladder attached thereto of rope, chain, or twisted galvanized wire, with wood or other
staves is conveyed through the window, the ladder being suspended from a rack
concealed, in a wood case within the window back, and so arranged as to be paid out,
or drawn up at pleasure.
When intended to be used for descent from the third floor, an additional length of
ladder would be made to depend from the projector so as to meet the required distance.
The projector will also suspend a light cradle depending therefrom-the cradle
being made to descend with the projector or to slide up and down by means of ropes
pullies, and other necessary appliances, so that an invalid or child may descend with
safety.
The Cradle & Ladder to be used either conjointly or separately, and the cradle

page_text: when required on the same projector, can be made to serve as a receptacle for the
ladder when not in use.
Those descending by the cradle are kept by the projector at a distance from the
lower windows, and out of reach of flames which might issue therefrom, and it is
especially intended to be of use where fires may be spreading rapidly.
When so required the projector will be suspended from a roller or cylinder by means
of ropes, and raised up and down by the turning of a windlass-the roller or cylinder
occupying the place of the wood case, and fixed within the window back secured
thereto by firm supports, and having a pulley wheel or wheels, with rope in readiness
for use by occupant of cradle in the absence of an assistant to turn the windlass.
The cradle to be connected with the projector by means of Chains or Stems of
twisted steel wire or other material capable of bearing a heavy strain, these would
pass through apertures made in the window sash and would rest on the window frame
so that the sash would close around them when shut down the orificos to be protected
from the weather by a covering of gutta percha or other substance.
The cradle having a sliding lid could be kept covered during its passage downward
if so required.
When the cradle is required to open communication with the floor immediately
beneath that from which it starts, the projector will be made to descend only so far,
and until the sides of the frame slope towards the building so as to form a suitable
incline for the passage of the cradle and it can be held in that position by the windlass
while the cradle is made to slide to the window intended to be reached. This is
accomplished by means of moveable clips or couplings attached thereto.
By allowing a slight further extension of rope the projector would incline in the
opposite direction, and the cradle made to return to the end of the projector to which
it was previously affixed thus being in readiness either for its further descent to the
ground, or for its return to the window it had previously left.
In some cases a framed seat of netted wire or other material would be substituted
for and occupy the place of the cradle, depending from the projector in the same
manner. This could be used with a single rope and pulley wheel or wheels if so
required, or with ladder only; and when the descent of same either with ladder or
ropes, or with rope only would be from a parapet or roof, or from a window with
blank wall immediately underneath then the width of projector would be adjusted to
suit the requirements of the several positions named.
In the case of a building with balcony intervening; or with lower windows jutting
out, or other deviation the projector would be made to meet the requirements of such
deviation by an alteration in length width or position and if necessary a short length
of drooping ladder would be added.
In Buildings not yet erected provision could be made in the construction to facilitate
the use of the projector.
That my invention may be the more readily understood I append a sheet of drawings
shewing the different arrangements of the projector.

page_text: 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 :-
1st. In a system of Life Saving Apparatus the application therefor, of an iron
revolving projector fixed in readiness for use substantially as described & shewn.

combination with a roller and windlass, and suspended cradle either with or without a
ladder, the cradle being kept at a distance from the building during descent also fully
described and shewn.
5th. For the use of the said projector and the application therefor in combination
