PROVISIONAL SPECIFICATION.
Improved Stopping and Locking Arrangement for Cage Hoists.
JAMES GODDARD, 384, Oldham Road, Bardsley, Ashton under Lyne, Mechanical
& Electrical Engineer, do hereby declare the nature of this invention to be as
follows:
-
By this arrangement hoists can be stopped & locked at any room by the move-
ment of a lever, and it works by spring action, & sliding movement, which opens &
closes two holes which allow the stoppers on the starting ropes or chains to pass
or not to pass through, and to be applied for stopping only or locking only, with
the same arrangement, and both are worked by one lever movement. By this
arrangement there are two stoppers instead of one as generally used.
Improved Stopping and Locking Arrangement for Cage Hoists.
JAMES GODDARD, Electrical Engineer, 384, Oldham Road, Bardsley, Ashton
under Lyne, 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:-
Fig. 1 is plan showing the lever handle B up and hole C open and sliding
arrangement P, N, out of connection.
Fig. 2 is plan with the sliding part A in section.
Fig. 3 is the front view with lever handle B down.
Fig. 4 is side elevation with lever handle B up and sliding arrangement out of
connection.
Fig. 5 is the same as Fig. 2 but without the sliding arrangement N, P, S.
Fig. 6 is side elevation same as Fig. 4 but without the sliding arrangement N,
P, S.
E is fastened on one side the cage of hoists by bolts or ordinary wood screws.
N is wood with a metal faceing which is fitted down all the length of the
hoist well wall. S is a open space in the sliding arrangement (N) at every room.
F are bolts which screw into É and a nut on the back. The other end their are
two nuts one on each side of O which hold O in a fixed position. When the lever
handle B (which is fasten to A by the split pin R) is up as shown on Fig. 1, 2, 4,

page_text: 5, 6, springs M are closed which are held from having any action on the part A
by the fork end of the lever B being flat on the surface O and the bolls P are not
in contact with the sliding surface N and the hole C is full open and has no griping
action on the ropes or chains and stopping bobbins on the starting rope or chain
can pass through except the top and bottom bobbins which are made large enough
so that they can never pass through whether the lever handle B is put down or
not. The hole C to be lined with india-rubber for griping the rope or chain when
required. When the lever handle B is put down as shown on Fig. 3 it allow
the springs M to have their full action on A but as shown on the sliding arrange-
ment N, S, P, the springs M can only move A until the bolls P come in con-
tact with the surface N but when the bolls P come to the open space $ in N it
allow A to move and grip the rope or chain or when bobbins are used on the rope
or chain A can only move until it come in contact with E. Which do not grip the
rope or chain but closed sufficient to prevent bobbins on the rope or chain from
passing through at any room.
The space S in the sliding surface N is made large enough for to allow the
stopping bracket to move the rope or chain only a certain distance until the
driving strap is on the loose pulley or for direct driven hoists by electric motors
to move the switch for a certain distance until the current (electric) is cut off and
then releases the grip of the starting rope or chain or let bobbins pass through (when
bobbins are used) when the bolls P come on the contact surface N which caused A
to move hackward and open the hole C (or holes) so that it is impossible for the
rope or chain or electric switch to be moved too far if the cage happen to slip
the brake by it own velocity.
The drawings on Sheet 2 show the stopping and locking arrangement without
the sliding arrangement N, P, S, A, which can be used with one or two holes C
either for griping the starting rope or chain for locking or for stopping by hobbins
fasten on the starting rope or chain of cage hoists with the same mechanical
arrangement with one lever handle movement and spring action. When anyone
get in the cage of the hoist from top or bottom room or any room if they want to
stop at the room following they put the lever handle B down (when by the action
of the springs M, A will move until it come in contact with E) any time before
they get to the room they require to stop at when the cage will stop itself at that
room caused by the bobbins on the starting rope or chain not being enable to pass
through the hole C which caused the rope or chain to be moved until the belt is
on the loose pulley or for electric hoists until the electric current is cut off by the
switch.
If they do not want to stop at the room following they leave the lever handle B
up which stop the springs M from having any action on the sliding part A until they
have passed the room next to the one they require to stop at.
Persons before they leave the hoist should see that the lever handle B is up or else
anyone from above or below cannot move the rope or chain for to start the hoist.
For locking the hoist for allowing to unload any goods from the cage.
When
the hoist is stopped they put the handle B down which allow the springs M to act
on A which caused the hole C to grip the rope or chain or close until A come in
contact with E which is closed sufficient enough to prevent the locking bobbins
from passing through (when hobbins are used) so that no one can move the starting
rope or chain until the lever handle B is lifted up. By this arrangement cage
hoists either working with straps or direct electric driven hoists can be stopped and
locked at any room by spring action caused by the movement of a lever handle
and by sliding arrangement fasten down one side of the hoist well wall when
the hoist will stop itself at the following room by the movement of the rope or
chain by griping arrangement or by the movement of the rope or chain by
coming in contact with bobbins fasten on the starting rope or chain.
And starting ropes or chains can be locked when the cage is stopped by the
movement of a lever handle either by griping the rope or chain or by the sufficient

page_text: cluseing of a hole so that bobbins fasten on starting ropes or chains cannot pass
through which stop anyone from moveing the rope or chain until the lever handle
B is lifted up:
And the hoist cannot reverse itself which occur in hand stopping as the stopping
bracket is thrown out of action when it has travel pass a open space and it need
no judgement in stoping the hoist as with hand stopping because the lever handle
can be put down or knock down anytime so simple in arrangement alway one
direct pull of the starting rope or chain by it action.
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 opening and closeing of one or two holes by spring action and one
lever handle movement.
(2) To work by sliding arrangement or without.
(3) The sliding arrangement to be fasten down one side of the hoist well wall
with wood and a metal surface fastened upon it with a open space at every room.
(4) To be used for griping starting ropes or chains of cage hoists or with bobbins
fastened upon the rope or chain at every room,
(5) The stopping hole or holes to be lined with india-rubber or without.
(6) The sliding surface to be of wood with metal fastened on the front of it.
