A New or Improved Safety Gear for Colliery Cages and other Hoists
or Lifts, and in Apparatus connected therewith.
We, JOSEPHI ASPINALL, of 56, Blackledge Street, Collier, and FREDERICK
ASPINALL, of 17, Prescott Street, Collier, both of Daubhill, Bolton, in the County
of Lancaster, do hereby declare the nature of our said invention to be as follows:-
This invention refers to a new or improved safety gear for colliery cages, and
other hoists or lifts and in apparatus connected therewith and consists in automatic
means for arresting and holding or catching the cage in case the chain or rope
carrying the same breaks, by which life and property will be saved. This we
carry into effect by mounting suitable spring levers or their equivalents to any
convenient part of the cage by means of bolts or centres. Between the spring
levers or their equivalents is disposed a cone or wedge shaped piece attached to
a rod coupled to a lever mounted in a fixing secured to any convenient part of
the cage; the other end of the said lever being coupled by a chain or its equivalent
to the hook connecting the same with the winding or hoisting rope or chain.
The ends of the spring levers or their equivalents are provided with serrated
surfaces to grip the guiding rods or slides when released by the cone or wedge
shaped piece being raised by the action of the connecting lever when the winding
rope or chain breaks. The gripping levers may be duplicated so as to operate
on one or more guiding rods. This apparatus is equally applicable to hoists or
lifts employed in hotels, mills, and other places.

DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation of a colliery cage with our invention applied for arrest-
ing and holding or catching the cage in case the carrying chain or rope breaks.
A is the cage; B carrying chain or rope; Chook to which is attached the carrying
chain or rope; D chains or ropes for attaching cage to hook C, and E guiding
rod or rods or slides on each side of cage.
To the cage A are secured the spring levers G by the bolts or centres H.
Between the spring levers G is disposed the cone or wedge shaped piece I attached
to the rod J coupled to the lever K by the pin L. The lever K is mounted in the
fixing M secured by the bolts N to the upper side of the cage A; the other end
of the said lever K being coupled by the chain 0 and tightening link P to the
hook C, thereby connecting the same with the winding or hoisting chain or rope B.
The ends of the spring levers G are provided with the serrated surfaces T to
grip the guiding rods or slides E when released by the cone or wedge shaped
piece I being raised by the falling action of the longest end of the connecting
lever K when the winding chain or rope B breaks. The gripping or spring
levers G may be duplicated so as to operate on one or more guiding rods. This
apparatus is equally applicable to hoists or lifts employed in hotels, mills, and
other places.
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:-
The general arrangement construction and combination of parts composing our
new or improved safety gear for colliery cages and other hoists or lifts, consisting
of the spring levers G provided with the serrated surfaces T and the cone or wedge
shaped piece I on the rod J connected to the lever K mounted on the fixing M; the
other end of the lever K being coupled by the chain 0 and tightening link P
to the hook C attached to the carrying chain or rope B; the whole being connected,
applied, and operating substantially as described and as illustrated in the annexed
drawings.
