An Improved Fire Escape.

page_text: An Improved Fire Escape.
I, CLAUDE RAJOT of Renaison in the Department of the Loire, Republic of
France Mechanician, do hereby declare the nature of this invention to be as
follows:-
The improved fire escape consists of three parts, namely an endless ladder, the
upper support therefor and the lower tensioning holder.
The ladder is composed of rope, chains or flexible bands to which the rungs are
fixed by chains and whipping or otherwise. This ladder is slung over two rollers
or pulleys of suitable breadth journalled parallel to each other in the upper
support which may be a bracket fixed in the outside wall of the house or building
or one carried by adjustable posts or bars with suitable stays to be temporarily
fixed at any window. The ladder is of sufficient length that is lower loop may
near touch the ground or place to which descent is to be effected and it there
passes under two parallel rollers journalled in a carriage or frame capable of being
secured in place by hooks or otherwise so that it cannot lift under the tensioning to
be given to the ladder. This tensioning of the ladder is produced by displacing
one or each of the last mentioned rollers from the other for which purpose the
trunnions of said rollers or their bearing blocks are carried in slots along which
they may be displaced by rack and pinion gear and prevented from returning by
ratchets.

An Improved Fire Escape.
I, CLAUDE RAJOT of Renaison in the Department of the Loire, Republic of
France, Mechanician, 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 improved fire escape consists of three parts, namely an endless ladder A,
the upper support therefore and the lower tensioning holder.
In the annexed drawing
Fig. 1 is a front elevation partly in section of the fire escape. Fig. 2 is a side-
elevation thereof.
Fig. 3 shows the construction of the upper bracket when the latter is to be
detachable and adjustable to any window or opening.
The ladder A is composed of ropes, chains, or flexible bands to which the rungs a
of wood are fixed by chains or cords and whipping or otherwise. The ends of this
ladder are attached together by hooks b b extra lengths being similarly inserted if
desired and it is slung over two rollers or pulleys B of suitable breadth journalled
parallel to each other in the upper support C which may be a bracket fixed in the

page_text: outside wall of the house or building or one carried by adjustable posts or bars with
suitable stays to be temporarily fixed at any window. The ladder is of sufficient
length that its lower loop may nearly touch the ground or place to which descent
is to be effected and it there passes under two parallel rollers D journalled in a
carriage or frame H capable of being secured in place by hooks or otherwise so
that it cannot lift under the tensioning to be given to the ladder. This tensioning
of the ladder is produced by displacing one or each of the last-mentioned rollers D
from the other for which purpose the trunnions of said rollers D or their bearing
blocks are carried in slots along which they may be displaced by rack and pinion
gear d F and prevented from returning by ratchets e engaging in the racks G.
The bracket shown in Fig. 3 comprises two posts formed each of two parts L, L',
connected by sleeve E having set screws 6' 6' and by strap C', so that its length is
adjustable for different heights of window opening or the like. On the part L'
the end of the horizontal arm E' is engaged by sleeve D' with set screw d¹. The
arm E¹ carries the pulleys B B and it is also supported by the post F1 hinged to
it at and adapted to rest on the window sill. Post F¹ is connected to post L L'
by strap I the post L L' is also spaced from the wall if needed by the bars H'H'
abuting against the uprights G¹.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to he performed I declare that what I
claim is :-
In a fire escape
1. A fixed or movable bracket carrying two rollers adapted to support a rope
Indder.
2. A flexible ladder having hook or other connections at its ends for constituting
it into an endless ladder which may be extended by insertion of additional lengths.
3. A carriage carrying two rollers adapted to be separated by rack movement
to give tension to an endless ladder fixed as described.
4. The construction of removable bracket as described with reference to Fig. 3.
