PROVISIONAL SPECIFICATION.
A New or Improved Safety Gear for Colliery Cages and other Hoists
or Lifts and in Apparatus connected therewith.
I, JOHN MORGAN, of 38, Morris Green Lane, Daubhill, Bolton, in the County
of Lancaster, Coal Miner, do hereby declare the nature of my 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 auto-
matic 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
I carry into effect by attaching to any convenient part of the cage in close
proximity to the guide rods suitable fixings provided with a chamber or passage
to slide up and down on the said guide rods. In the said fixings are located
metallic eccentrics provided with serrated surfaces for gripping the guide rods
in case the hoisting chain or rope breaks when the cage is ascending or descending.
The hoisting chain or rope is attached by chains or rods to a lever attached to
a shaft mounted in bearings on the aforesaid fixings secured to each side or
corner of the cage. Each shaft carrying the metallic eccentrics may be provided
with a suitable spring arrangement or its equivalent to ensure of the apparatus
operating automatically immediately the hoisting chain or rope breaks. Each
eccentric shaft is provided with a lever to be actuated by suitable stationary stops
disposed at the top and bottom of the colliery shaft or other hoist or lift, by which
the serrated surfaces of the metallic eccentrics are kept out of contact with the
guide rods when the cage is resting on the stops at the top and bottom of the
colliery shaft, hoist or other lift. This apparatus may be duplicated so as to
operate on one or more points of the guiding rods according to the length
of the cage, each set of apparatus being connected by rods, chains, or other
equivalents in any desired manner. This apparatus is equally applicable to
hoists or lifts employed in hotels, mills, and other places.

and ascertained in and by the following statement:-
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 auto-
matic 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
I carry into effect by attaching to any convenient part of the cage in close

to slide up and down on the said guide iods. In the said fixings are located
metallic eccentrics provided with serrated surfaces for gripping the guide rods
in case the hoisting chain or rope breaks when the cage is ascending or descending.
The hoisting chain or rope is attached by chains or rods to a lever attached to
a.shaft mounted in bearings on the aforesaid fixings secured to each side or

with a suitable spring arrangement of its equivalent to ensure of the apparatus

eccentric shaft is provided with a lever to be actuated by suitable stationary stops
disposed at the top and bottom of the colliery shaft or other hoist or lift, by which
the serrated surfaces of the metallic eccentrics are kept out of contact with the
guide rods when 'the cage is resting on the stops at the 'top and bottom of the
colliery shaft, hoist or other lift. This apparatus may be duplicated so as to
operate on one or more points of the guiding rods according to the length
of the cage, each set of apparatus being connected by rods, chains, or other

DESCRIPTION OF DRAWINGS.
Fig. 1 is a longitudinal side elevation of a colliery cage with my new or
improved safety gear applied. Fig. 2 an enlarged side view of my invention
when out of gear during the up and down motions of the cage in the colliery
shaft. Fig. 3 an enlarged side view of my invention when in gear in case the
carrying chain or rope breaks when the cage is ascending or descending the
colliery shaft. Fig. 4 a side elevation of lever when in contact with stops at
top and bottom of the colliery shaft to prevent the serrated surfaces engaging
with the ordinary guide rods. Fig. 5 an enlarged front elevation of my new or
improved gripping apparatus. Fig. 6 a plan of Fig. 5, and Fig. 7 a transverse
section through line A B in Fig. 5.
In all the figures the same letters are employed to indicate corresponding
parts.
C represents so much of a colliery cage as is necessary to illustrate my inven-
tion; hoisting or carrying chain or rope, and E the ordinary guide rods.
To the colliery cage C are attached the fixings G each being provided with the
chamber or passage H to slide up and down the ordinary guide rods E. The
fixings Gare secured to the colliery cage C by the bolts F. In the fixings G
are located the metallic eccentrics I provided with the serrated surfaces J for
gripping the ordinary guide rods E in case the hoisting or carrying chain or
rope D breaks when the colliery cage C is ascending or descending the colliery
shaft. The hoisting or carrying chain or rope D is connected to the hook K in
the usual manner, and the latter is connected to the colliery cage C by the
chains or ropes L by means of the bolts M. In the fixings G are mounted the
shaft N to which are attached the metallic eccentrics I provided with the serrated
surfaces J. On the shaft N is mounted the lever 0; the outer end of the latter
being attached to the hook K by the chain P. The shaft N carrying the metallic
eccentrics I is provided with the spiral springs Q to ensure of the apparatus
operating automatically immediately the hoisting, winding or carrying chain or
rope breaks. One end of each spiral spring Q is secured to the side of the
fixing G by the set screw R; the other end of the said spiral spring being attached

page_text: by the set screw S to the disc T mounted on the eccentric shaft N. Each eccentric
shaft N is provided at one or both ends with the lever V which is actuated by
coming in contact with suitable stationary stops W disposed at the top and bottom
of the colliery shaft, by which action the serrated surfaces J of the metallic
eccentrics I are kept out of contact with the ordinary guide rods E when the
colliery cage is resting on the usual stops employed at the top and bottom
of the colliery shaft. This apparatus may be duplicated so as to operate on one or
more points of the ordinary guide rods E, such as the middle or bottom end of
the colliery cage C; each set of apparatus being connected by rods, chains,
or other equivalents in any desired manner. This apparatus is equally applicable
to hoists or lifts employed in hotels, mills, warehouses, and other places.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
The general arrangement construction and combination of parts composing my
new or improved safety gear for colliery cages and other hoists or lifts, consisting
of the fixings G each being provided with the chamber or passage H to slide up
and down the ordinary guide rods ; the fixings G carrying the shaft N on which
are mounted the eccentrics I provided with the serrated surfaces J for gripping
the ordinary guide rods E in case the hoisting or carrying chain or rope D breaks
when the cage C is ascending or descending; the shaft N with the eccentrics I
being operated by means of the spiral springs Q secured at one end to the fixing G
and at the other end to the dise T mounted on the shaft N, together with. the
levers V mounted on the shaft N and operating with the stops W fixed at the
top and bottom of the colliery shaft, hoist or lift, to prevent the serrated surfaces J
of the eccentrics I engaging with the guide rods E, the whole being connected
applied and operating substantially as described and as illustrated in the annexed
drawings.
