WO ABEL HEYWOOD, Junior, of 58 Oldham Street, Manchester, in the County of
Lancaster, Publisher and EDWARD MCGEE, of Henrietta Street, Manchester aforesaid,
Joiner and Builder do hereby declare the nature of said Invention for IMPROVEMENTS
IN SAFETY APPLIANCES FOR THE CAGES OF HOISTS OR LIFTS to be as follows:- ..:
The object of our Invention is to prevent the serious and often fatal accidents which
result at present when persons or things fall down the wells of hoists or lifts.
We attain this object by suspending from the cage a light wire or other platform or
a series of such platforms according to the number of floors in the building.
The first platform is connected to the cage by collapsible or telescopic connections
such as chains, rods or tubes and the second platform, if there be a second platform is
connected to the first by a similar connection and so on in like manner throughout
the series of platforms.
When the cage is at the bottom of the well the platforms and connections lie
telescoped or one upon the other but as the cage rises the platforms are drawn up into
position level with their respective floors and are thus ready to catch and support any
person or thing that may fall into the well below the cage.
We propose to use the above described arrangement in combination with a similar
safety appliance suspended from the roof of the well the platforms being carried up
and the connections collapsing or telescoping as the cage rises and falling into position
again as the cage descends; or we may dispense with chains, rods, or other connections
for the wire or other platforms above the cage and support the said platforms on
brackets or catches from which the platforms will be lifted by the rising cage and
deposited again in their places as the cage descends.

page_text: We ABEL HEYWOOD, Junior, of 58 Oldham Street, Manchester, in the County of
Lancaster, Publisher, and EDWARD. MCGEE, of Henrietta Street, Manchester aforesaid,
Joiner and Builder, do hereby declare the nature of said Invention for IMPROVEMENTS
IN SAFETY APPLIANCES FOR THE CAGES OF HOISTS OR LIFTS, and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
The object of our Invention is to prevent the serious and often fatal accidents which
result at present when persons or things fall down the wells of hoists or lifts.
We attain this object by suspending from the cage a light wire or other platform or
a series of such platforms according to the number of floors in the building.
The first platform is connected to the cage by collapsible or telescopic connections
such as chains, rods, or tubes and the second platform, if there be a second platform
is connected to the first by a similar connection and so on in like manner throughout
the series of platforms.
When the cage is at the bottom of the well the platforms and connections lie
telescoped or one upon the other but as the cage rises the platforms are drawn up into
position level with their respective floors and are thus ready to catch and support any
person or thing that may fall into the well below the cage.
We propose to use the above described arrangement in combination with a similar
safety appliance suspended from the roof of the well, the platforms being carried up
and the connections collapsing or telescoping as the cage rises and falling into position
again as the cage descends; or we may dispense with chains, rods, or other connections
for the wire or other platforms above the cage and support the said platforms on
brackets or catches from which the platforms will be lifted by the rising cage and
deposited again in their places as the cage descends.
And in order that our Invention may be fully understood and readily carried into
effect we will describe the accompanying Sheet of Drawings, reference being had to
the figures and letters marked thereon.
Figures 1 and 2 are elevations illustrating our Invention as applied to a hoist or lift
in a five storied building, the cage being shown opposite the first floor in Fig. 1, and
at the top of the hoist well in Fig. 2. Fig. 3 is a plan of one of the platforms which
we employ below the cage and Fig. 4 a plan of one of the platforms which we employ
above the
cage.
The principle of the Invention will be readily apparent on glancing at these views
in which
a is the hoist well, the cage and 6 the rope to raise and lower the same; e ce are
the platforms suspended from and below the cage by means of collapsible or telescopic
connections in this case the chains d at such distances apart that when the cage is at

page_text: the top of the well a as shown in Fig. 2, each platform e comes opposite one of the
floors e.
When the cage descends the platforms c are deposited one upon the other at
the bottom of the well and the platforms ffff which we employ above the cage b
then come into operation.
When the cage b is in the position shown in Fig. 1, one of the platforms f rests
upon the top of the cage and each of the remaining platforms frests upon suitable
brackets or catches placed opposite a floor e but when the cage rises it lifts the
platforms from their respective supports and carries them to the top of the well as
shown in Fig. 2.
When therefore the cage is at the bottom of the well the aperture at each floor is
closed by one of the series of upper platforms the series of lower platforms lying
one upon the other at the bottom of the well but when the cage rises the platforms f
are carried up one by one and the platforms c are gradually drawn up into their
positions. We have shown and described as many platforms above and below the
cage as there are floors to be protected it is however obvious that a greater or smaller
number of platforms may be used.
Our invention may be applied to hydraulic, steam, or any other class of hoist or to
the shafts of mines rendering it impossible for persons to fall down a shaft or for
accidents to occur through objects falling down the shaft.
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed we declare that what we claim is―
1. The combination with the cage of a hoist or lift, of a platform or a series of
platforms suspended from and below the said cage by collapsible or telescopic
connections for the purpose specified.
2. The combination with the cage of a hoist or lift of a platform, or a series of
platforms supported above the cage or suspended above the cage by means of
collapsible or telescopic connections, substantially in the manner herein set forth.
3. The combination with a platform, or a series of platforms suspended from and
below the cage of a hoist or lift, of a platform, or a series of platforms suspended
above the cage by means of collapsible or telescopic connections or supported above
the cage, all substantially in the manner herein set forth.
