Improvements
SAMUEL GREEN BENNETT of Saint Leonards, Selborne Road, Handsworth
in the County of Stafford, Engineer do hereby declare the nature of this invention
to he as follows:--
This invention relates to improvements in connection with my Patent No. 13111
dated September 28 1887.
In lieu of the arrangement therein described for suspending the frame Min
which the strikers are fixed, I arrange for the frame M to be so fixed to the cage
as to travel with it, the suspending chain K being thus dispensed with. At the
top of the cage I place two or more levers. These levers are constructed so that
they work freely on axles or pivots. The inner ends of these levers-that is those
ends projecting towards the centre of the cage-are attached by means of a shackle,
or any other method, to the sustaining chain or rope which carries the cage. The
outer or other ends of the levers are cranked, so that they pass through slots formed
in the upper ends of the frame M or they may be attached by any convenient joint.
Between the axle or pivot, and the outer ends, a chain or rope is attached to each
lever. The other end of these chains is attached to the balance weights of the
lift. The action of these levers would therefore be as follows-So long as no
accident arises through the breakage of the sustaining rope, the levers would remain
stationary. If however the sustaining rope should break, the balance weights
would at once cause the outer ends of the levers to rise a few inches-the extent
of this movement being regulated in any convenient manner. As the frames M
are attached to the outer ends, they are drawn upwards also, since they work in
slides attached to the sides of the cage. This movement is regulated so as to be
just sufficient to prevent the strikers engaging the steps, with the result, of course,
that the cage would at once rest upon the first step which presents itself to the
falling cage, thus preventing the accident.

Improvements in the Construction of Hoists or Lifts.
SAMUEL GREEN BENNETT, formerly of Saint Leonards, Selborne Road
Handsworth, in the County of Stafford, Engineer now of 29 Station Road
Handsworth in the same county do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
nud ascertained in and by the following statement:-
This invention relates to improvements in connection with my Patent No. 13111

falling cage, thus preventing the accident.
Specification No. 2185. Final Specification.
In the accompanying drawings Fig. 1 represents a side clevation of cage of hoist
and Fig. 2 a front elevation of same. The cage is shown at A the guide C is fixed
in the well-hole of hoist, generally on each side of cage although they can be
placed in other positions if required. To these guides are attached a series of
steps F mounted on suitable spindles G. These steps project beyond the guides
but when the cage is ascending it lifts them, as will be obvious on reference to the
drawings, thus allowing the cage to pass. When however the cage is descending
it is necessary for the steps to be raised to allow it to pass, and in the present
invention, I do this by means of the strikers L which are mounted on a frame M.
This frame is fixed to the cage A and therefore travels with it. At the top of cage
are shown two levers a. mounted so that they will work freely on the axles b.
The inner ends of these levers of c are attached, either by means of a shackle or
direct as shown in drawings to the sustaining chains or ropes d. The outer ends
of these levers are cranked as shown at e Fig. 1 and the extreme ends at pass
through slots g formed in the upper ends of the frame M or they may be attached
by any convenient joint. At ha chain or rope is attached to each fever. These
chains pass over a pulley in the overhead gear, the other ends of these chains
being attached to the balance weights of the lift. If the sustaining chains d should
break the balance weights operating through the chains would at once cause the
outer ends of the levers at to rise upwards, which engaging with the frame M causes
same also to rise, the distance being so arranged as to be just sufficient to prevent
the strikers lifting the steps, thus causing the falling cage at once, to rest upon the
first step which presents itself, and thereby preventing the accident.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is
1. The construction and use of the frame M with the strikers L fixed to the
cage of hoist and travelling with same as herein before described.
2. The construction and use of the levers a or any modification thereof
embodying the principle of the invention, used in combination with the frame M
and strikers L for the purpose of actuating same as herein before described.
