We Alfred CHARLES HEWITT and GEORGE WILLIAM PYKE of 56 High
Street Maidenhead Berks Electricians do hereby declare the nature of this inven-
tion to be as follows:-
The fire escape is made of wire cable attached to moveable brackets which are
bolted through walls under the eaves of the roofs of high buildings then carried
down between the windows to other brackets at the lower part of the premises when
they are tightened by adjustable screws or swivels. The escape is permanently fixed
30 that it can be easily reached by persons from the windows on either side in case
of fire, a slight movement of the bracket caused by extra weight on the escape rings
an electric bell as a warning against an unlawful entrance to the building being
made, the space between the wall and the escape being adapted for advertisement.

Improvements in and connected with Fire Escapes.
We, ALFRED CHARLES HEWITT, and GEORGE WILLIAM PYKE, both of
56 High Street, Maidenhead, in the County of Berkshire, Electricians, 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 :-
Our invention relates to improvements in and connected with fire escapes, which
consists of a wire cable attached to brackets bolted to walls of buildings, (the said
wire cable being a part of the escape) and adjustable screws or swivels.
The escape
is permanently fixed together so that persons can escape in case of fire.
A slight movement of the escape caused by weight on the escape, rings an electric
bell as a warning against an unlawful entrance to a building where the aforesaid
apparatus is fixed.
And in order that our invention may be thoroughly understood, we now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Fig. 1, is a section of a wall with the apparatus fitted inside and outside a building.
Fig. 2, is an elevation of the escape fixed on the outside of a building.
Fig. 3, is a view of the vibrating contact apparatus drawn to an enlarged scale.
Parts of the figures are broken off for want of space.
The apparatus is constructed with wire cables 6 which form the sides of the
ladder or escape, and to the said wire cables b we fix wire rounds e covered with
tubes. The cables 6 are fixed to adjustable screws a' bolted at the top and bottom
of the ladder to brackets a, these said brackets a are fixed to the wall h by means
of bolts and nuts f. An electrical circuit' wire 9 is connected from an ordinary
electric alarum-bell d to the vibrating contact c and wire cables b.
At or near the top of the ladder we fix a bracket h' this said bracket is fitted with
a terminalj and adjusting screws i, i, as in Fig. 3. Between the points of the

page_text: adjusting screws i, i, is inserted loosely the vibrating contact c which is fixed to a
collar on one of the cables b. The collar k is provided with a terminal 2.
This fire escape is attached to brackets a which are bolted through walls / under
the eaves of the roofs of buildings or in any convenient place, it is then carried
down and attached to brackets at suitable points at the lower part of the building.
where adjustable screws a¹ are used so as to make the ladder rigid.
Any slight movement of the escape causes an electric circuit which is attached to
au indicator to give an alarm.
The object of our invention is to provide an apparatus that is uninflammable to
be fixed to any building for the purpose of persons escaping when a building is on
fire..
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a fire escape and an electrical alarm, the combination of the brackets a
adjustable screws a¹, wire cables and rounds e with tubes to form the ladder, with
the vibrating electrical contact c electrical circuit wire 9 and alarm-bell d, sub-
stantially as herein described and according to the accompanying drawing,
2. In a fire escape and an electrical alarm, the combination of the various parts
of the apparatus constructed as hereinbefore described.
