improvements in the Construction of Hoists or Lifts.
SAMUEL GREEN BENNETT, of Saint Leonards, Selborne Road, Handsworth in
the County of Stafford Engineer do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in connection with my Patent No. 13,111
dated September 28, 1887.
Instead of the strikers being of the patterns described in the above mentioned
specification, I employ strikers which are bell-cranked in shape, and they are so
arranged that if they come into contact with a step (as therein described) which
will not rise to allow them to pass they will themselves lift up and so clear the step,
thus preventing accidents to the striking gear. To the tails of some or all of the
strikers I attach a light rod thus actnating them independently if necessary for any
special purpose I may require.
I also fix on the top of cage a governor similar to what is used for steam engines.
This governor is actuated by a rope which is guided by means of suitable pulleys
into and out of the actuating wheel of the governor. To the governor, an 1 working
in connection with it, are attached suitable levers connecting with the tails of one
or more of the strikers. If the cage should develop undue speed owing to over-
loading or breaking of the suspending rope, the governor would of course at once
act upon the levers which would slightly raise the tails of the strikers, which would
thus be thrown out of gear and cause the cage to rest immediately on the step which
had in consequence not been removed in time for the cage to pass it.
A governor as described could also be used when suspending ropes are not
employed-as for example in a ram lift, the striking gear being actuated as
described in case of an accident.

COMPLETE SPECIFICATION.
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
and ascertained in and by the following statement :-
This invention relates to improvements in connection with my Patent No. 13,111
dated September 28th 1887.
Instead of the strikers being of the patterns described in the above mentioned
specification, I employ strikers which are bell-cranked in shape, and they are so
arranged that if they come into contact with a step (as therein described) which
will not rise to allow them to pass they will themselves lift up and so clear the step,
thus preventing accidents to the striking gear. To the tails of some or all of the
strikers 1 attach a light rod thus actuating them independently if necessary for any
special purpose I may require. I also fix on the top of cage a governor similar to
Price 8d.1

page_text: what is used for steam engines. This governor is actuated by a rope which is
guided by means of suitable pulleys into and out of the actuating wheel of the
governor. To the governor, and working in connection with it, are attached
suitable levers connecting with the tails of one or more of the strikers. If the
cage should develop undue speed owing to overloading or breaking of the
suspending rope, the governor would of course at once act upon the levers which
would slightly raise the tails of the strikers, which would thus be thrown out of
gear and cause the cage to rest immediately on the step which had in consequence
not been removed in time for the cage to pass it. A governor as described could
also he used when suspending ropes are not employed, as for example in a ram lift,
the striking gear being actuated as described in case of an accident.
In the accompanying drawings, Fig. 1 shows a side elevation of the cage of
hoist, and Fig. 2 a front elevation of same.
The cage is shewn at A the guide rails at C containing the safety steps F which
are fully described in my Specifications No. 13,111 of 1887 and No. 2185 of 1896.
Instead of the strikers being of the patterns therein de-cribed, I prefer to make
them bell-cranked in shape as shewn at a since such an arrangement will permit
them to lift up when required so as to clear the step so as to prevent accidents to
the striking gear.
To the tails of some or all of these bell-cranked levers I attach a light rod b, the
upper end of which is attached to the lever e Fig. 2, the other end of the lever e
being attached to the fulerum d. On the top of the cage I fix a governor e which
is actuated by a rope which is guided by means of suitable pulleys g into and out
of the actuating wheel of the governor, the rope being suitably fixed at the top
and bottom of the well-hole of lift. It is obvious that if the cage should develop
undue speed the governor would at once act and, by raising the levere lift at the
same time the rod b, and the bell-crank strikers a which thus being thrown out of
gear would not operate the steps F so that in case of accident owing to the cage
falling the cage would at once be stopped owing to its resting on the first step
which presents itself after the governor operates the above mentioned levers.
I sometimes place inside the cage a small chain or rope i Fig. 2 for the purpose
of acting upon the strikers independently if required. This small chain is made to
pass either over one of the pulleys g or over another suitable pulley provided for
the purpose, and it is attached to the strikers coupled together by means of the
rod, or it may be attached to one of the strikers only. This small chain
enables the lift attendant to lock the cage on a step in any position at any
moment.
It is obvious that the governor can be made to actuate a series of bell-cranked
levers on each side of the cage if they are so placed, instead of one side only as
shewn in drawings.
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 1
claim is
1. The construction and use of strikers bell-cranked or other suitable shape for
the purpose described, or any modification thereof.
2. The rod connecting the said strikers as hereinbefore described or any
modification thereof either working in combination with a governor, or independently
as shewn at i Fig. 2.
3. The use of a governor as herein before described for the purpose of actuating
the said strikers as hereinbefore described.
4. The use of an independent chain or cord i Fig. 2 as hereinbefore described or
any modification thereof.
