page_text: We WILLIAM LUMB cotton spinner and RICHARD HENRY HOLT clerk both of
Brotherod near Rochdale in the county of Lancaster do hereby declare the nature
of this invention to be as follows:-
Our Improvements consist as follows-To the rope chain or other means by
which the cage is lifted or lowered we connect a rod or other mechanism, which
when the weight of the cage is on the rope (or other means by which the cage is
lifted) keeps this rod in position. To this rod is attached a bar (or bars) at or
near the inner ends of the bar (or bars) but so as to allow the rod to move up and
down when required. This bar (or bars) rest on or pass through slots or grooves
formed in or attached to the cage. The bottom of these slots or grooves, act as
fulcrums for the bars to rest upon, and the top of the slots or grooves prevent the
bars rising too high. When the chain (or other means by which the cage is lifted)
breaks, the rod falls to which the inner ends of the bar (or bars) is connected.
When the inner end of this bar (or bars) falls, it raises the outer end of the bar
(or bars) into contact with the sides of the Hoist race or Lift, or racks or other
mechanism fixed to the Hoist race, and these prevent the cage falling to the bottom,
when the chain or other means by which it is lifted breaks-Springs or weights
may be applied to the bars or rod to accellerate the action.

page_text: We WILLIAM LUMB cotton spinner and RICHARD HENRY HOLT clerk both of
Brotherod near Rochdale in the county of Lancaster do hereby declare the nature
of our invention for IMPROVEMENTS IN 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 :—
To the rope chain or other means by which the cage is lifted or lowered we
connect a rod or other mechanism which when the weight of the cage is on the
rope (or other means by which the cage is lifted) keeps this rod in position. To
this rod is attached a bar (or bars) at or near the inner ends of the bar (or bars)
but so as to allow the rod to move up and down when required. This bar (or bars)
rest on or pass through slots or grooves formed in or attached to the cage. The
bottom of these slots or grooves act as fulcrums for the bars to rest upon, and the
top of the slots or grooves prevent the bars rising too high. When the chain (or
other means by which the cage is lifted) breaks, the rod falls to which the inner
ends of the bar (or bars) is connected.
When the inner end of this bar (or bars) falls it raises the outer ends of the
bar (or bars) into contact with the sides of the Hoist race or lift; or Racks or
other mechanism fixed in the Hoist race and these prevent the cage falling to the
bottom when the chain or other means by which it is lifted breaks.
Springs or weights may be applied to the bars or rod to accellerate the action.
In order that our Invention may be fully understood and readily carried into effect
we will proceed to describe the accompanying drawings reference being had to the
figures and letters marked thereon. Fig. 1 is a side and Fig. 2 a back elevation of
a host or lift according to our invention. a is the cage. 6 the chain by which it
is lifted (but a rope or other means may be used) c is a rod which is connected to
the chain at 61 (but so that the weight of the cage is not on it) This rod passes
down the back of the cage (but it may pass down or through the cage in any con-
venient way) and is kept in position by the pullies d which will allow it to drop
easily when required. On the bottom end of the rod c and under the cage is
mounted at their inner ends the bars e and e¹ by means of the pin f. These bars e
and el pass through slots in the brackets g and g¹ which are attached to the cage
and are thus kept in position. The bottom of these slots act as fulcrums for the
bars to rest upon and the top of the slots prevent the bars rising too high. The
projections g² are also to prevent the bars e and e¹ rising too high at their outer ends
(The outer ends of these bars in place of being pointed as shown, may be formed
circular so as to jamb against the sides of the hoist) Its mode of action is as
follows; suppose the chain b (or other means by which the cage is lifted) breaks,
then the rod c drops carrying the pin f on which the inner ends of the bars e and e¹
are mounted and thus they drop too, but as the bars e and e¹ rest on the bottom of
the slots in the brackets g and g¹ the outer ends of the bars are raised into contact
and forced into the sides h of the Hoist race or lift, and thus the cage is prevented
falling to the bottom. Racks or other means may be fixed to the sides or other

page_text: convenient part of the Hoist for the bars e and e¹ to take hold of when the chain
or other means by which the cage is lifted breaks if preferred.
Weights or springs may be applied to the rod c or bars e and e¹ to accellerate
their action--and more than one rod c may be used but we prefer it as shown when
applied to an ordinary cage.
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:-
1st. Applying the bars e and e¹ which support the cage when the chain (or other
means by which it is lifted) breaks, under the cage which has to be supported,
substantially as shown and described.
2nd. Attaching the rod c (by which the bars e and e¹ are actuated) to the chain
or other means that lifts the cage so that the weight of the cage is not on this rod
substantially as shown and described.
3rd. Supporting the bars e and e¹ by means of brackets with slots through which
the bars pass, and which act as fulcrums for the said bars substantially as shown
and described.
4th. Applying the bars e and e¹ so that when the chain or other means by which
the cage is lifted) breaks they will jamb against or into the walls of the Hoist race
substantially as shown and described.
6th. The general arrangement and construction of the improved Hoist or
Lift substantially as hereinbefore described and represented in the accompanying
Drawing.
