Automatio Arrangements for Opening, Olosing, and Locking Doors for
Hoist Well Openings.
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 doors for hoist wells openings can be open when the cage
is either going up or coming down at any room the cage comes to, and are
closed and locked as the cage moves away from any door (or room) by automatic
action which can be applied to sliding folding and roller doors arrangement.
There are two trigger boxes B with triggers R fastened on the cage C for opening
any door when the cage C is going up or coming down and their are two
metal brackets E fastened on the cage C one at the top and one at the bottom
which are connected together by a length of flat iron on front, (or wood metal
covered) which are for moveing the locking trigger T & T 1 by coming in contact
with the bolls O.
Fig. 1 is the elevation in section showing the arrangement for opening doors
when the cage C is going up. For sliding doors (and could be used for roller
doors).
Fig. 2 is the elevation in section showing the arrangement for opening doors
when the cage C is coming down, for sliding doors and for opening the doors
coming up and going down for folding and roller doors arrangement.
Fig. 3 is the elevation in section showing the locking arrangement for sliding
and roller doors which show the cage coming up and going down. The locking
part of the trigger T moves downward only when E come in contact with the
bolls O.
Fig. 4 is the elevation in section showing the position of locking arrangement
when the cage is stopped at any door for sliding and roller doors.
Fig. 5 is section elevation showing locking arrangement for folding doors for
hoist well openings.
When the cage C is coming up or going down the trigger T move upward
when E comes in contact with the bolls O instead of downward as in the locking
arrangement for sliding and roller doors.
For opening sliding doors when the cage is going up the trigger N is fitted
in the box B which is fitted into the door D (as shown on Fig. 1) and when the
boll O come to the open space M the trigger N move upward which allow the
trigger R to pass which allow the door D to fall down (or close). When the
cage C is coming down the trigger R move upward so has no action on
the trigger N only when the cage is going up.
For opening the doors when the cage C is coming down the trigger N is
fitted in one of the balance weights W (as shown on Fig. 2) of the door which
is attached to the door with flexible wire ropeing but the door is the heaviest
so that it closed itself by it own weight.
The weight W is at the top of the glide box S S when the door is closed

page_text: and when the cage C come down the trigger R (which is fitted in the box B on
the cage C) come in contact with the trigger N which moves untill the bolls O
comes to the open space M in the sliding box (S S) when the trigger N move
downward which allow the trigger R to pass (or if the cage C is stopped it hold
the door open). When the cage has passed, a certain distance by any opening
the door closes itself.
The slide boxes S S are lined on two sides with metal (or made of metal).
When the cage C is going up the trigger R move downward so it has no action
on the trigger N only when coming downward. A is a metal box or plato to
cover the open space M in the sliding box S S.
For roller doors the trigger N is fitted to two weights the same as shown
on Fig. 2 one on each side of the door which is attached to the roller (that winds
the door up) by flexible wire ropeing or leather belting on flange or grove pulleys
one weight is at the top when the other is at the bottom that weight which
is at the top the rope or belting is coiled round the pulley and the weight that
is at the bottom is uncoiled one is to open the doors when coming down and
the other in going up. The door is weighted so that it closes itself when the
trigger N come to the open space M in the sliding box S S which allow the
trigger N to move so that the trigger R (which is fitted in the box B which is
fixed on the cage C) to pass by.
For opening folding doors in coming up or going down the trigger N is
fitted in two weights same as shown on Fig. 2 and work in sliding boxes the
same as Fig. 2 one on each side one weight is at the top when the other is
at the bottom the open space M is at the top in one sliding box S S and at
the bottom in the other and one weight is made heavy enough to pull the doors
together and the other weight is made heavy enough to open the doors when
one weight is lifted up by the trigger R coming in contact with trigger N.
When the boll 0. in the trigger N come to the open space M in the sliding
box S S it allow the trigger R to pass by. The weights are attached by wire
rope or leather belting to pulley on each end of the shaft F which is fixed
across the top of the door.
When any of the weights are at the top the rope or belting is coiled round
the pulley which it is attached to and when any of the weights at the
bottom the rope or belting is all uncoiled off as the doors are opra al closed
and one weight go up and the other down. The heaviest weight is alway at
the bottom when the doors are closed. On each end of the shaft which the
weights are attached is fitted a bevil wheel which gear into bevil wheels which
are fitted on upright shafts which the doors are fastened to on each side of the
hoist well openings so that when the shaft across the top of the doors is moved
round by the weights going up and down by the action of the triggers R and N,
the doors are opened and closed by the bevil wheel gearing at each end of the
shafts.
There is also fasten on one end of the cross shaft a catch wheel I as shown
ou Fig. which is for locking the door with when it closes.

page_text: this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement;-
-
Reference is hereby made to the accompanying drawings in which similar
figures of reference indicate corresponding parts.
Fig. 1 is a side elevation in section showing the arrangements for opening
hoist well doors when the cage is going up. It shows the trigger N fitted in
the metal box B which fits into the door 1) and shows the trigger R which fits
into a metal box B which is fitted at the top of one side of the cage in front of
the door.
Can be applied for sliding and roller doors.
As the cage C (when ascending) comes to any door R it will come in contact
with N and lift D up, and when the floor of C comes to the same level as the
floor of the room where D is, D is open sufficient to allow any persons to get
out of C, and as C moves away (when ascending) 1) will move upward about
eight inches when O will come into M when N will move upward and allow R
to pass by when D will at once fall down (close the opening between the hoist
well and the room) by allowing 1 to move about eight inches upward. C is
not compelled to be stopped exactly at the floor level for D to keep open but
if C descends from D after being stopped O will not come into M but N will
remain in contact with R until has left it. If any person in C does not want
any door (when ascending) to open, by pulling P downward R will move upward
and prevent R from coming in contact with N.
When C descends the curved end of R comes in contact with the curved
end N, but N does not move but R moves upwards in the slot in B.
Fig. 2 is a side elevation in section showing the arrangement for opening
hoist well doors when the cage is descending. It shows the trigger N fitted into
the balance weight W (which is attached to the door by flexible ropeing or
straping) and the trigger R1 which fits into the box B which is fitted at the
bottom of the cage in front, but on the opposite side to Fig. 1. It can be
applied for sliding roller and folding doors. When C descends RI comes in
contact with N when C comes to any door, and pulls W down until 0 gets to
the space M (which pulls the door up) when N moves downwards and R1 pass
by. When D being the heaviest comes down (or close) and W goes up again.
P is for anyone to pull R1 down so as to prevent its action on N at doors
required to be passed.
When
comes
Fig. 3 is a side elevation in section for opening hoist well doors.
the cage C is ascending (can be applied for sliding roller and folding doors).
1 comes in contact with N at each door and lifts W up but when
to W it falls down again because N moves upward and R can pass.
Doors are open when W is lifted up (by the opposite weight W attached
to D) or in case of folding doors open outward.
Fig. 4 is a side elevation in section showing the locking arrangement when
combined with the automatic opening arrangement for folding or roller doors
when the trigger T2 is required to more upward. It shows E just coming in
contact with on T2 when C is descending and shows E just coming in contact
with O on T1 when C is ascending and 1 locked by T2 and 1. When the
floor of C comes to any door in descending T2 is lifted up and when the top
of C comes to any door in ascending T1 is moved upward which lifts T2 up
by the chain or rope attachment. When C is at the hoist well opening O on
T2 & T1 is upon E which prevents the locking end of T2 from falling down
until Chas moved away. The boxes B with T1 & T2 are fastened on one side
of the hoist well opening.
Fig. 5 is a side elevation in section showing the locking arrangement for
hoist well doors when combined with the automatic opening arrangement when
the trigger T is required to move downward. It shows the door locked and
the brackets E E just coming in contact with the triggers when the cage is
ascending. When C (in descending) comes to any door E comes in contact

page_text: with O on T, when the locking end of T which is in D1 moves downwards in
the slot in B and then D can be opened. When C is ascending E comes in
contact with O on T1 which moves upward and by the connection H, T moves
upward which moves the locking end of T downwards and allows 1 to be opened.
Fig. 6 is a side elevation in section showing the position of E E, E1 T and TI
when C is in front of any hoist well opening and D unlocked, (but in its closed
position). The brackets EE to be fitted one on the top of C and one on the
bottom of C so that the front edge of one aide of C corresponds with E1 when
required.
Fig.7 is a side elevation in section showing the locking arrangement when
the doors are opened by hand and shows the door locked by the trigger T.
Can be applied for sliding and roller doors. When C is ascending and gets to
any door, E comes in contact with O on T which moves upward and the locking
end of T moves downwards in the slot in B, and El comes into contact with O
on T as C gets opposite to D which allows 1) to be lifted up by hand. When C
is descending and gets to any door E comes in contact with O on T3 and
moves T3 into the slot D2 into a horizontal position, and when D is lifted
up 13 moves upward into D2 but when the bottom of the door has passed
by T3 it falls down again into the horizontal position and prevents D from
coming down until C moves away.
Fig. 8 is the same as Fig. 7 but showing the position of the trigger T and T3
when the door has been opened by hand. T T3 are held in that position
until C moves away when 13 will fall down and allow D to close and T will
fall down and the locking end will come into D1 which prevents D from being
lifted up when the cage is not at any room. Fig. 9 are front, side, and section
elevations of an arrangement to prevent doors opening which are desired to
be passed and which can be set so as to open any particular door. The trigger
wheel R2 has the same number of triggers as there are hoist well doors. The
box B1 is fastened on the sides of C by wood screws, and when any one gets
into C he moves the handle H to any number to correspond to the room he wants
any door to open. For example, if C was at the bottom room and the door at
the fifth room was required to open, the handle I would have to be moved to
No. 5 on B 1. When C came to the first door R2 would be moved one tooth
at each door it came to before it got to No. 5 when it comes in contact with N
as shown on Fig. 1, 2 & 3. When it came to mumber 5, the door X would be
in the position as shown which cannot move farther, as the ledge Z
prevents it as it is double the thickness of the other teeth so when it comes
in contact with N at the fifth door (room) it causes the door to be opened as
shown by Fig. 1, 2 & 3. When C is descending R2 or X cannot open any door
at is moves a tooth at every N it comes in contact with. When used for opening
any door when descending, R 2 and X are in a reverse position as shown by R3.
E E are brackets which are fastened on one side of the cage in front, one
on the top of the cage and one on the bottom in a line with the front edge of
the cage or they can be fastened on the front of the cage on one side one at
the top and one at the bottom and joined together by a length of flat iron or
wood covered with sheet iron as shown on Fig. 6 by E1 (or E E1 E may
be cast as one_bracket). These curved brackets E E are for moving the
triggers T T1 T2 T3 as they come in contact with them as the cage moves
up and down. They are fastened on the cage either with ordinary wood screws
or set screws or bolts.
El is a peice of flat iron or wood covered with sheet iron which is fastened
with screws at each end to the two brackets E E and is in full contact with
rollers when at any door.
C is a side of the cage to show the position of the trigger boxes B and the
brackets E.
T is a locking trigger which works on a pin which is riveted to the box B
and in one end of the trigger is a slot in which a roller O fits which tuins

page_text: round on a pin through it centre. The other end of the trigger works in a
slot in the box B and goes into the slot D1 in the door when the door D is
closed and prevent the door from being opened.
T1 is a trigger which is only for the purpose of moving the locking trigger
by the connection H when the cage is ascending by means of the curved
brackets E coming in contact with O so that the door D is unlocked before the
automatic opening arrangement comes into action.
T2 is a locking trigger for folding or roller doors the locking end of which
moves upward when the cage is decending by the bracket E coming in contact
with the roller O on T2, causing the door (or doors) to be unlocked. It also
moves upward when the cage is ascending, by the bracket E coming in contact
with the roller O on T1 through the action of the chain or wire rope attached
to the end of T1 as shown on Fig. 4.
T3 is a trigger for holding doors up when they are opened by hand and
letting them fall as the cage moves away from them on account of the end of
the trigger opposite to the roller end being the heaviest as shown on Fig. 7.
When the bracket E El comes in contact with the roller on T3, one end
of T3 is brought into a horizontal position as shown on Fig. 8. But when
the door D is moved upward T3 will move into a upright position to allow the
door to pass, but when the bottom of the door is moved up past T3 it falls
back into its horizontal position and prevents the door from coming down
because T3 cannot come below the horizontal position as long as the roller O
is in contact with El as shown on Fig. 8.
BB are trigger boxes which are fastened one on each side of the cage one
at the top for the trigger R to work in to open doors when the cage is ascend-
ing, and one on the bottom at the opposite side for the trigger R1 to work
in to open doors when the cage is descending. There is a slot in each of the
boxes B B for the trigger to work in. The boxes B B are fastened with ordinary
wood screws to the cage.
B1 B1 are alternative trigger boxes to take the place of B B, one for the
trigger wheel R2 to work in and one for the trigger wheel R3 to work in,
which has a slot in front which is so shaped that it will allow the trigger
wheel R2 or R3 to turn round so as not to act on the trigger N until the
trigger marked X is brought into a horizontal position when the ledge marked Z
will prevent it from moving and cause it to open the door which it next comes
to as shown on Fig. 9. P P are wooden bobbins which are attached by light
cords to one end of the triggers R and R1 so that any person in the cage not
desiring the doors to open which he wishes to pass may, by pulling one of the
bobbins P P downwards, move one of the triggers R or R1 so that they would
not have any action on the trigger N.
R is a trigger for opening doors when the cage is ascending only.
.It
works upon a fixed pin in the box B. The end which comes in contact with
the trigger N is the heaviest so that it will keep in a horizontal position.
When the cage is descending the trigger R moves upward in the slot in the
box B when it comes in contact with the trigger N, so it has not any opening
action on the trigger N except when the cage is ascending.
R1 is a trigger for opening doors when the cage is descending only. It has
the same action as trigger R but that end which comes in contact with trigger N
is the lightest so that it will not fall down but keep in a horizontal position.
When the cage is ascending the trigger will move downward in the slot in the
box B when it comes in contact with the trigger N so that it has no opening
action on trigger N except when the cage is descending.
K2 is a trigger wheel for opening doors when the cage is ascending which.
may have any number of triggers to correspond with the number of rooms
through which the cage passes. It works upon a fixed shaft in the box B1
and can be set to open the doors of any particular room by means of a handle
or pointer which fits on its shaft. The trigger X is thicker than the others

page_text: as shown by Fig. 9. The pointer is put back as many points as doors desired
to be passed and the wheel R 2 is moved one point by the action of trigger N
at every door so that the trigger X is in position to act on the trigger N_at
the door at which it is desired that the cage should stop. R3 similar to R2
but is required for opening doors when the cage is descending. It has the same
action as R2 but is placed on the opposite side of the cage and the other side
up.
Y is a spring to prevent the trigger wheela R2 or R 3 from moving more than
one point when they come in contact with the triggers N.
H is a length of flat iron or round iron flattened at each end. One end fits
into a slot in the trigger T and the other end fits into a slot in the trigger T1.
Both ends are attached to the triggers with split pins.
H is for moving the trigger T when the cage is ascending.
DD are door sections.
D1 is a alot in the door for the trigger T to fall into so as to prevent the
door from being opened by hand when the cage is not at such a door.
D2 is a slot in the slide S S to allow the movement of the trigger T3 co
that T3 will come under the door when the door is lifted above it as shown on
Fig. 8.
SS are slides for sliding and rollers doors to move in, but for roller doors
they would only require to be the same length as the doors.
$1 81 are slides boxes for the weight W to work in. If made of wood two
sides of them would be covered with sheet metal or the whole boxes could be
made of metal in one piece. There are spaces M M in the slide boxes S1 81.
M M are spaces in the slide boxes S1 81 to allow the trigger N to move
upward when the door has been lifted it full height so that the trigger R can
pass by and allow the door to close (or fall down). The space M at the top
of the slide box 81 is required when the door is being opened by the cage
ascending and the space M at the bottom is required when the door is being
opened by the cage decending.
A is a metal box or plate to cover the space M in the sliding boxes S1 S
when the slide boxes are made of wood. But when the slide boxes are made of
metal it would all be cast together. W is a metal weight to balance the doors
and there is a slot in the weight for the trigger N to fit in and there are at
the bottom of the weight two rollers 01 fitted in the weights by pins which
are rivetted to the weight going through their centre. The rollers work loose
in order to reduce the friction when the weight is working up and down in the
slide box S1.
F is a shaft which is fixed across the top of the door (or doors) which works
in brackets at each end. It can be used for sliding roller and folding doors.
When used for roller doors the shaft F fits in a wooden roller and on one end is
a flange pulley and on the other end is a flange pulley with catch 1 combined
as shown on Fig. 4 by 1 & 2. On the flange pulley at each end of the shaft
are attached the balance weights as shown on Fig. 2 and 3 by wire ropeing or
chain or belting.
When the door is closed one weight is at the top and one at the bottom.
When the door is open the position of the weights is reversed; one weight goes
up as the other goes down. When any weight is at the top the rope chain
or belting by which it is attached to the Hange pulley is coiled round such pulley
whilst the other rope chain or belting which is attached to the opposite Hange
pulley is uncoiled. The doors are balanced so that they fall down themselves
when the cage moves away. The weight which is at the top when the cage is
descending is pulled down by the action of the trigger RI on the trigger N.
When the cage is ascending the trigger R comes in contact with the trigger N
fitted in the weight which is at the bottom and lifts it up. The opposite weight
which is at the top is so balanced that it comes down and pulls the door up. The
·door can be locked by the arrangement as on Fig. 4 or by the one shown on
.

page_text: Fig. 5 or as shown on Fig. 5 without the catch 1 or the same as Fig. 5 but with
the slot in the bottom of the door instead of being at the top. In such case
the trigger T1 would be at the top and the locking trigger T at the bottom of
the door.
1 and 2 is a flange pulley and catch combined which can only move one way
untill the trigger T2 is lifted up (or if the trigger T is used moves downward)
which then allows the door (or doors) to be opened by the automatic arrange-
ment. When the cage moves away from the door (or doors) T2 falls down (or
if T is used it moves upward) and allows the catch I to move one way only so
as to allow the door to close.
The door cannot move in the opposite direction unless El is in contact with
the rollers on T T1 or T2.
For opening folding doors the same arrangements is used as for roller doors
except that there is a bevel wheel extra at each end of the shaft F which gear
into two bevel wheels which are fitted on two vertical shafts one on each side
of the hoist well opening which work in footsteps at the bottom and brackets
at the top.
The two half doors are fastened to the vertical shafts so that when the shaft F
across the top of the doors is moved round by the weights going up and down
by the action of triggers R R1 and N the doors are opened and closed by the
bevel wheels gearing at the end of each shaft. The doors open from the centre
and are locked by the arrangement as shown on Fig. 4 or by the
one as shown on Fig. 5 and 6 by T T1 and H. The locking folding
doors only leaving them to be opened by hand but to close themselves
as the cage moves away the trigger T2 and the box B or the trigger T
and box B can be used singly when there would be one on each side at the top
of the hoist well opening and a catch wheel and flange pulley combined (one
catch would be reverse to the other) on each end of the shaft F. One trigger
would act as a lock when the doors was open so that the doors could not_close
until the cage had moved away, and the other as a lock when they closed. There
would be a small bracket on each side similar to E E1 E on Fig. 6. When
the cage came to any door El would come in contact with one trigger and allow
the doors to be opened and as the cage moved away El on the opposite bracket
would come in contact with the other trigger and allows the doors to close them-
selves by the action of the balance weights. The balance weights when the
doors are to be opened by hand would not have a slot or trigger N fitted in them
and both of them would go up and down together not one up and the other
down as in the automatic opening arrangement. For opening sliding doors when
the trigger N is fitted in the box B as shown on Fig. 1 both the balance weights
would go up and down together and the rope chain or belting by which they
were attached to the door would have one end fastened to the doors and the
other to the weight on each side of the door.
The object of my invention is to do away with the danger of hoist well open-
ings. My improvements can be applied for sliding roller and folding doors
so that such doors will unlock and open as the cage of a hoist come to them,
and close and lock themselves as the cage leaves them either ascending or
descending, or can be applied in such a manner as to cause the doors to close
and lock themselves as the cage leaves them and to unlock as the cage comes
to them leaving them to be opened by hand Or be applied in such a manner
as to cause the doors to open and close only (without locking).
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
