PROVISIONAL SPECIFICATION.
An Improved Safety Apparatus for Mining Cages, Hoists, and other
similar Purposes.
We JOSEPH BRINDLE of 14 Field Street Failsworth in the County of Lancaster,
Mechanic RICHARD LOVETT READE of New Hall Wythenshaw Road Sale in the
County of Chester Merchant JOHN TAYLOR of 181 Northenden Road Sale in the
County of Chester Merchant and CLEMENT JOHN HALL of 3 Hale Lane Failsworth in
the County of Lancaster, Cashier do hereby declare the nature of this invention to be
as follows
The object of this invention is to prevent the falling of the cage or hoist in the
event of the breaking of the hoisting rope, chain, or band, or of the breakage or
failure of the hook.
To the framing at the top of the cage or hoist we attach two or more fixed cones
through the interior of each of which passes one of the fixed metal ropes or guides.
Within each of these fixed cones is placed a loose cone divided vertically into two
or more sections and carried at one end of a lever which works upon a fulcrum
supported upon a lower part of the frame of the cage or hoist.
The inner end of each lever is connected by a link to a weighted lever below, which
is also provided with a strong spring.
The levers which carry the divided cones are held out of action and support the
weighted levers by means of catches which are connected by chains to the lifting
hook.
If the main hoisting chain, rope, or band should break the catch chains fall loose
and release the catches; the weighted levers and springs then come into action draw
down the inner ends of the cone levers, thereby raising their outer ends, which thrust
the divided cones upwards into the inside of the fixed cones, which causes the divided
cones to be forced together so as to grip the metal guides and thus the cage or hoist
is suspended.
A lever or implement is provided whereby when the hoisting rope chain or band or
the hook has been replaced or repaired the movable cones levers & catches may be
returned to their original position ready to act again when required.

COMPLETE SPECIFICATION.
An Improved Safety Apparatus for Mining Cages, Hoists, and other
similar Purposes.
We JOSEPH BRINDLE of 14 Field Street Failsworth in the county of Lancaster
Mechanic RICHARD LOVETT READE, of New Hall Wythenshaw Road Sale in the
County of Chester, Merchant, JOHN TAYLOR of 181 Northenden Road Sale in the
County of Chester Merchant, and CLEMENT JOHN HALL of 3 Hale Lane, Failsworth
in the County of Lancaster, Cashier 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 object of this invention is to prevent the falling of the cage or hoist in the
event of the breaking of the hoisting rope, chain or band, or of the breakage or failure
of the hook.
The nature of the said invention and the manner in which the same is to be per-

page_text: formed or carried into practical effect will be readily understood on reference to the
annexed sheet of drawings and the following explanation thereof.
Fig. 1 on the drawing is a side elevation of a cage or hoist with our improved safety
apparatus shown as applied thereto, and Fig. 2 is a vertical section of a portion
thereof detached and drawn to a larger scale.
To the framing a at the top of the cage or hoist we attach two or more fixed cones b
one of which only is shown at Fig. 1. (see also enlarged section Fig. 2) through the
interior of which passes one of the fixed metal ropes or guides c on which the cage or
hoist works.
Within each of these fixed cones is placed a loose cone d which is divided
vertically into two or more sections and is carried in a fork at one end of a lever e
which works upon a fulcrum carried by a bracket f fixed to the frame.
The other end of each lever e is connected by a link g to a weighted lever / below
and is also attached to a strong spring i.
The levers e which carry the divided cones d are held out of action and support the
weighted levers 7 by means of catches (see also side view detached Fig. 3) which
catches are connected by chains / to the lifting book or ring m.
If the main hoisting chain rope, or band should break or the hook should fail, the
catch chains 1, become loose and the catches k fall into the perpendicular position
shown in dotted lines at Fig. 3, releasing the weighted levers h which with the
springs i then come into action, drawing down one end of the cone levers e, thereby
raising the forked ends which thrust the divided cones d upwards into the inside of
the fixed cones b which causes the divided cones d to be forced or wedged together
so as to grip the metal guides c tightly and thus the cage or hoist a is suspended.
A hand lever or implement is provided whereby when the hoisting rope, chain or
band, or the hook has been replaced or repaired the movable cones, levers, and catches
may be returned to their original position ready to act again when required.
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 :-
The improved safety apparatus for mining cages, hoists and other similar purposes
substantially as hereinbefore described and illustrated by the drawings annexed, and
especially we claim, the combination of the fixed cones with the loose divided inner
cones (through both of which the fixed metal rope or guide passes) for gripping the
said rope or guide whenever the hoisting chain, rope, or band breaks, or if the hoisting
hook or ring fails.
