PROVISIONAL SPECIFICATION.
Controlling Arrangements for Switches for Direct Driven Cage Hoists
and General Electric and Motor Work.
JAMES GODDARD, Electric Engineer, 366, Oldham Road, Bardsley, Ashton
under Lyne, do hereby declare the nature of this invention to be as follows:-
Fig. 1 is a elevation showing metal surfaces which are for making and
breaking the circuit in connection with the magnet coils M (which are fitted
down one side of the hoist well wall) for throwing the motor switch automatic
out of action at any room when the handle H on trigger bracket Fig. 9 has been
moved in a horizontal position (which stop the small boll on the spring trigger
from coming in contact with the surface S3) before the cage get to any room
which it is require to stop at, when the circuit in the magnet coils M is broken
between the first open space on S it comes to which allow the weight W to
throw the switch out of circuit.
Fig. 2 is simalar to Fig. 1 but the metal surfaces $3 are at different distances
from the metal surfaces S by this arrangement their will be one trigger bracket
as shown on Fig. 9 for surfaces S and one for each surface S3 for breaking the
circuit in the coils M at any particular room (to throw the motor switch out of
circuit) by lifting any trigger out of connection (at any time by the handle H)
when the cage will stop at such room where the trigger is out of connection
with the surface where it would have to come into contact if the handle had
been down.
Fig. 1 is simalar to Fig. 1 but without the switches S1 but $3 being
permanent connected to surfaces S.
Fig. is a view showing the surface S all in one length on the hoist well
wall by the use of this arrangement the controlling of the switch at any room
(for stoping the cage) except top and bottom' would depend on the attendant.
Fig. 3 is a front elevation showing the (electric) controlling arrangement when
the motor switch is not fixed in the cage which show it in it off position.
Fig. 4 and 11 is plan and elevation showing the controlling arrangement for
starting slowly by hand when the switch is fixed in the cage (A would not be on
when used for Fig. arrangement).
Fig. 5 is a front elevation showing the (mechanical) controlling arrangement
for reversing switches either when fitted in the cage or on the hoist well wall.
Fig. 6 is a side view of L P and B on Fig. 3 and 5.
Fig. 7 is a view of the bracket for stoping at any room for the arrangement as
shown on Fig. 5.
Fig. 8 is a plan of the trigger T1 with a extra trigger T3 (when the switch
is fitted in the cage) for controlling the stoping by automatic action at any room.
Fig. 9 is a small trigger bracket with spring action which is fitted on the
top on one side of the cage (or in one side of the cage) which are used to work
in contact with with the surface S and S3.
Fig. 10 is a small bracket with the spring trigger arrangement which is used
when the motor switch is fitted in the cage and also for making contact with

page_text: the wire S2 (as shown on Fig. 1 and 2) they are fastened on the top on one
side of the cage and each conducting wire between the motor and the switch
passed through the grove pulleys which are in spring contact with each wire.
The conducting wires are fastened to insulators one at the top and bottom of the
hoist well wall.
Fig. 12 is a view of the trigger on Fig. 5 when the trigger is thrown out of
action by hand movement for stoping at intermediate rooms.
Fig. 13 shows the position of the bracket Fig. 7 by automatic stoping at top
and bottom and at any room.
$1 are switches which are fixed at every room except top and bottom room
so that the cage can be brought from above or below by any person at any room
which by breaking the circuit on any of the switches it cause the circuit in the
magnet coil M to be broken when the cage come to such room: When the
inotor switch is thrown out of action by the weight W and the cage stop.
$3 are metal surfaces which are fixed one at every room except top and bottom
they are for making and breaking the circuit in the magnet coils M automatic at
any room the cage come to which is controlled by the handle H on the small
trigger bracket as shown on Fig. 9.
S are metal surfaces which are in direct connection with the magnet coils M
as. shown by the lines which reperent insulated wire.
$2 is a bare copper wire which run all the length of the hoist well wall
which is fastened at each end to insulators which has one end in direct connec
tion to the last segment on the switch by which the circuit is completed to the
magnet coils M by the two grove pulleys on the trigger bracket as shown on
Fig. 10 which the wire S2 passed between them which is connected direct to the
trigger which is in contact with the surface S.
M is a pair of magnets which are fastened on the back of the switch box (the
coil of the magnet to be either series or shunt wound) which are brought into
circuit when the last segment on the switch is brought into connection.
A is a metal disc which has attached to it a chain wheel either made up of
stampings wrought iron or cast steel or mallable iron or cast iron (which is
fitted on the switch shaft at the back of the switch box) or when used as
shown on Fig. 11 would all be made in one piece. There is a stud N fitted on
(or cast on) which is for coming in contact with the stopping pieces on the back
of the switch box to prevent the switch from being moved to far in
starting either by rope or handle arrangement the disc A is held into position
by the magnet when the circuit is made in them.
L is a two grove pulley one grove for the starting rope to work in and one for
the rope or chain attached to the weight W and there is attached to the pulley
a small chain wheel P which work in connection with the chain (A1) wheel
attached to A.
W is a weight which is made heavy enough so as to move the switch quickly
out of circuit when the magnet circuit is broken (or when the trigger T1 is
moved backward).
T1 are triggers with spring action which are for holding the switch in position
(as shown on Fig. 5) when the switch has been moved its full distance. There
are loose bits attached to the end which moves upward to allow the stud N to
pass but fall down into a horizontal position when N has passed which stop
the switch from falling out of connection untill the trigger T1 is moved back-
ward.
T is a lever which work on the stud X (which is fitted on the back of the.
switch box) which is for moving the trigger T 1 out of action to let the stud N
on A1 to pass. T can be moved automatic by coming in contact with the
brackets as shown on Fig. 13 in which case the switch would be fixed in the
cage but when the switch was not fixed in the cage the lever T would be
moved by rope attachment to the one end of the trigger except when the cage
came to the top when Fig. 7 would be fasten to the top of the cage which

page_text: would come in contact with one of the lever T which by it action would move
the trigger T1 backward.
Rare small brackets fastened on the back of the switch box (or cast to it) they
have square holes for the triggers T1 to work in.
T3 is a loose trigger (which fits into triggers T 1) with a boll at one end
which can be brought in or out of contact with the bracket Fig. 7 by the
handle and spring arrangement on one end when the cage is required to stop
at any room the handle H is put down when the boll O comes in contact with
the next bracket when the trigger T1 is moved by the action of the bracket 7
which allow the weight W to fall and pull the switch in it off position.
T2 is a trigger which take the place of T3 when the controlling of the
switch for stoping the cage at any room (except top & bottom) is done
by hand movement.
F are springs. The spring F as shown on Fig. 11 is for holding the handle
arrangement out of action after the switch has been put on so that when the
switch circuit is broken there will be no movement of the handle (which would
be liable to come in contact with anything). The handle when the switch is
started is pressed inward so that the wheel on the end of the shaft will come
into gear and when the handle is released throw itself out of gear.
L1 is a one grove pulley by which the weight W is attached either by rope
or chain.
01 are small bolls which have pins through there centres they are for
reducing the friction between the surfaces they come in contact with.
B is a hollow cast iron brick which into the wall which is for a stud to be fasten
to for the pulley L and chain wheel to work on.
Hare handles for controlling the movement of the triggers.
02 are small grove pulleys.
By this arrangement switches are either in direct circuit with the main or cut
off altogether and it is impossible for switches to be left half way on or half way
off and switches are brought slowly into circuit and the circuit is quickly
broken by the action of a weight W (or a spring) and can be applied to switches
for working reversing motors or direct driven motors and main switches as
shown on Fig. 5, 3, 4 and 11, except that there would only be one set of
triggers T T1 for direct driven motors and main switches instead of two as
shown on Fig. 5 can be applied for starting slowly by rope or chain arrange-
ment. or by handle as shown on Fig. 4 & 11 by worm and worm wheels or bevel
wheels or tooth wheels gearing and can be used for cage hoist for the switch
to be fixed in the cage and travel with it or be in a fixed position. And if the
switch circuit was broken by any cause or accidend as shown on Fig. 3 the circuit
in the magnet coils would be broken (because the magnet coils M are connected
direct in the switch circuit) when by the action of the weight W the switch
would be brought back to its off position so that it is impossible for any motor
to be started direct or without the current first passing through the resistance
coils. And for main and branch switches no fuse wires could be put in with the
switch in circuit. The circuit in the magnet coil is always broken when the
cage comes to the top or get to the bottom.. And by the arrangement S3 and S
and the small trigger brackets (Fig. 9) attachment on the top edge on one side
of the cage the circuit in the magnet coil can be broken automatic at any room
which allow the weight to pull the switch out of action (in it off position) and has
shown on Fig. 5 the cage always stops itself automatic at top and bottom.
can also stop automatic at any room by the arrangement shown on Fig. 7, 8, 6,
11, .13. And the cage can be brought from any room from above or below by
any person at any room as shown on Fig. 1 and 2 by the switches S 1 which are
fixed at every room except the top and bottom.
And
And when any person want the cage to come where he is he breaks the circuit
on the switch which is fitted on one side of the hoist well opening and then
start the switch by pulling the rope E attached to the switch when, the cage.

page_text: will come to the room required and stop itself automatic because the circuit being
broken in the sliding surface as shown by $3 or Fig. 1 and 2 the sliding bracket
which work on the surface S will only be in contact. So the circuit will be
broken by the space between $ (in the magnet coil which hold the switch
in position) when the weight W will fall and pull the switch in its off position.
The attendant must put the small switch $1 into circuit again before he got in
the cage or else the cage will stop at the same room again either ascending
or desending. And when used for main switches or for direct driven motors
a coiled spring similar to a clock spring could be used instead of a weight which
would be attached at the back of the switch box.

Controlling Arrangements for Switches for Direct Driven Cage Hoists
and General Electric and Motor Work.
JAMES GODDARD, of 366, Oldham Road, Bardsley, Ashton under Lyne, in
the County of Lancashire, Mechanical and Electrical Engineer, 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 means for controlling the operation of. switches such
as referred to in my Patent No. 5,423 of 1898 or to other switches and is
especially useful in connection with direct driven cage hoists, cranes and the like
and for general electric and motor work, the object being to provide a switch con-
trolling arrangement fixed in the cage so as to travel up and down with it; a
controlling arrangement fixed at the top of the hoist well and capable of being
started by a rope cord or the like from any room; a switch controlling arrange-
ment fixed outside the hoist well so that the hoist can be worked without any
need of a person being in the hoist; means for automatically throwing the motor
switch out of circuit in cage hoists both at the top and bottom portions of their
travel; means for automatically breaking the circuit of the motor switch in every
room of a building in which the hoist is working and means for automatically
breaking the circuit at any special room it is desired the hoist should stop at.
My invention will be fully described with reference to the drawings filed
with my Provisional Specification and also to the additional drawings filed here-
with.
Figs. 1 to 13 are drawings filed with my Provisional Specification and in
which
Figs. 1, 1, and Figs. 2 and 2ª, show side elevations of contact plates in con-
nection with which some of the triggers or switches hereinafter described work.

with a wire S running from top to bottom of the hoist well.

Fig. 13 is a side elevation showing an arrangement of cams or brackets such
as referred to in Fig. 7 and which are fitted to the side of the hoist well.
Figs. 14 to 17 filed with this Complete Specification show in
Fig. 14 an elevation of a trigger arrangement which is used for breaking the
circuit in the magnet coils,
Fig. 15 elevation of an arrangement showing a pair of magnets and weight
in connection therewith,
Fig. 16 side elevation of contact plates and wire fitted in the hoist well and
Fig. 17 a perspective sketch of the switch controlling arrangements.
In these drawings Fig. 1 shows metal surfaces S and S3, and their wire con-
nections which are fitted down one side of the hoist well from top to bottom,
the plates $3 being placed opposite to the gaps in the plates S. These plates are
for the purpose of enabling the triggers or controlling arrangements hereinafter
making and breaking the electric circuit automatically with the magnet coil M
indicated in Figs.. 3 and 15 at each or any room the hoist cage comes to as it
ascends or descends. Contact with these plates is made by trigger brackets or
switches fixed to the cage as indicated in Figure 17, the trigger brackets or
switches being shown in detail in Figs. 9 and 10. The trigger brackets shown
in Figs. 9 and 17 are fitted as will be seen from the latter figure on one side
of the cage a and are used for making and breaking the circuit in coil M by
means of rollers 01 coming in contact with S and S3 Figs. 1, 2, and 17. The
trigger consists of a rod 6 passed through a supporting bracket c and carrying
at its front end a pivoted switch handle H. When H is in a horizontal position
as in Fig. 9 roller O¹ cannot come in contact with S or S3; but when the handle
is placed in the vertical position as shown in Fig. 17 the rod 6 is forced out-
wards by spring d so as to put the roller 0¹ in contact with the surfaces $³. The
central trigger lever shown in Fig. 17 is in all respects similar to that shown at
the right hand side of the latter figure except that it has no handle H and is
always kept in contact with the plates S by spring d. The trigger lever shown
in Fig. 10 and at the left hand side of Fig. 17 is also similar to that shown in
the centre of Fig. 17 except that it has an additional roller 03 and is also per-
manently pressed towards the wire S which runs from top to bottom of the
hoist well and at each extreme end is secured to insulators. The rollers O¹
and are in permanent contact with the wire S2 which passes between them
and the whole arrangement is for completing the circuit to the trigger in Fig. 9
and forward to the magnet coils M. All the three triggers or switches are
connected in series and when the cage is moving there is a circuit from S² to S
and forward to coil M, or from S to S3 and S¹ to S and forward to M; but when
the circuit is broken at S¹, or the trigger which comes in contact with $3 is
disconnected by means of handle H. as in Fig. 17 the circuit in M is broken by
means of the spaces between S, S when the cage comes to any floor.
Fig. 2 is an elevation similar to Fig. 1 except that the metal surfaces §³ are
at different distances from S for each floor. By this arrangement there will be
one trigger as shown in Fig. 9 for each surface S3 which when thrown out of
action by means of a handle H on either of them, or by means of one of the
switches such as S¹ will cause the circuit in M (which controls the switch for
stopping the motor) to be broken when the cage arrives at the particular room
controlled by the trigger or switch S. For example a person getting into the
cage at the bottom room and wishing to go to the fourth room would move the
trigger out of action which would be opposite to the surface $3 at that particular
room so that when the cage comes to that room the circuit in M will be broken

page_text: by the space between the surfaces S; or, when a person in the room referred
to wishes to bring the cage to a standstill at the room in which he is he breaks
the circuit by turning the switch S¹.
or
Fig. 1a is similar to Fig. 1 except that the surfaces S³ and S are permanently
connected instead of having the small switches S at every room whilst Fig. 2
shows the metal surfaces S in one length and without the surfaces
switches S¹, by which arrangement, stopping, except at the top and bottom
rooms, will depend on the attendant breaking the circuit in M. In this arrange-
ment there are two triggers fixed to the cage, one as shown in Fig. 10 and at
the left of Fig. 17, which is in contact with wire S and one as shown in Fig. 9
and to the right of Fig. 17 in contact with S. The circuit is completed
through S by triggers to S and forward to M; but is broken at top and bottom
by trigger as in Fig. 9 going beyond the surface S.
In Fig. 3 and 15 M is a pair of magnet coils connected either in series or
shunt with a motor switch such as described in my prior Patent No. 5423 of 1898
and of which a is the switch shaft having fixed on it a disc A and a chain wheel
such as A Figs. 5 and 11. N is a stud in disc A and L, Figs. 3, 5 and 6,
is a double grooved pulley. P is a chain wheel fixed on the shaft carrying
the pulley L and which shaft is suitably supported from the side of the hoist
well. W Figs. 34, 5 and 15 is a weight attached to a chain w passing upwards
between rollers 0 and having its end attached to pulley L. E is a rope or
chain passing round the pulley L. and capable of being operated from any
door of the hoist well, or in the cage at any part of the hoist well. Referring
more particularly for the moment to Fig. 3 it will be understood that to start
the switch on shaft a¹ the rope E is pulled slowly, causing the pulley L and
chain wheel P to move, thereby lifting the weight W and by the chain con-
nection between P and A, the latter (which is an armature) moves till the
stud N comes in contact with the stopping pieces on the back of the switch
box as indicated in the before mentioned prior patent. This action completes
the circuit in the coils M and holds the armature A in position,, until the circuit
is broken in coils M by the arrangement shown in Figs. 1 and 2 and when
such circuit is broken the switch (fully described in my prior patent before
referred to) is pulled into its off position by the weight W as shown in Fig. 3.
In Figs. 4 and 11 the armature A is similar to that already described except
that it is arranged for starting slowly by hand. By this arrangement the circuit
between the motor and the switch-when used in connection with cage hoists
or lifts with reversing switches-would be made by means of triggers as shown
in Fig. 10 and wire S2 as in Figs. 1, 2, and 16. To start the switch the handle Ha
is pressed inward until the pinion B comes into gear with wheel A¹ on the switch
shaft. The handle H2 is then turned round as far as possible which brings
the switch into circuit. When the handle is released the pinion B will be
thrown out of gear with A¹ by the action of the spring F, leaving the switch
under the control of the magnet and the weight W.
In Fig. 5 the mechanical controlling arrangement for reversing switches shows
the mechanism in position when the switch is in circuit. The whole of this
arrangement is fixed at the top of the hoist well and to the side of the cage is
fixed a cam similar to that shown in Fig. 7 which will act on bowl O¹ when the
cage gets opposite the floor and cause the pivoted trigger lever T¹ to release N
and allow the weight W to pull the switch out of circuit as referred to in con-
nection with Fig. 3. For stopping at the bottom there would be a chain attach-
ment to Tso arranged that a projection carried by it could be acted upon
by the bottom of the cage so as to pull. trigger T outwards and so withdraw
its end from under the stud N, allowing the weight W to pull the switch out
of circuit as before described. When Fig. 5 without the mechanism L, P, R
and A¹ is fixed to the cage in conjunction with the mechanism shown in Figs. 4
and 11 there would be two cams such as indicated in Fig. 13 for every room
except the top and bottom ones, one to throw the motor switch out of circuit

page_text: when the cage is descending and the other to throw it out of circuit when the
cage is ascending. This mechanism would be under the control of a trigger
arrangement such as shown in Fig. 8 and which would take the place of
triggers T and T and would enable the cage to be stopped automatically at
any room when the handle H is put down just before getting to it. When the
stopping of the cage is intended to be left entirely to the attendant there would
not be any cams except one at the top and another at the bottom of the hoist
well and the trigger would be at the same as shown in Fig. 8 except that T3
and handle H would be fixed to T instead of movable and would require to be
moved backwards by the handle H to allow the weight W to pull the switch out
of circuit at any room except top and bottom.
The side elevation in Fig. 6 shows more clearly the double grooved pulley L
and chain wheel P secured to a bracket by means of which the mechanism is
supported from the hoist well wall.
The trigger arrangement shown in Fig. 8 is used when the motor switch
is fitted in the cage and takes the place of T and T on Fig. 5. The portion T³
is carried by the bar T on the end of which T¹ is formed. When the handle H
is in a horizontal position, as shown, the end of the fork being in contact with
the metal plate through which T3 works holds the latter back and prevents the
roller O from coming in contact with any cam 7, such as that shown in Fig. 7
except those at the top and bottom of the hoist well which are wider than the
others. When the handle H is put down the spring F on 13 will force the
latter outwards and bring O in line with cams 7. On O¹ coming into contact
with any cam 7 the bar T and its end T¹ will be moved. backwards.
The trigger shown in Fig. 12 takes the place of T and T in Fig. 5 when
required for ordinary motor work or main switch and is to control the breaking
of the circuit by sliding the trigger bar backward by means of the fixed
handle H so that stud N as shown in Figs. 3 and 5 can pass and allow the
weight W to pull the switch out of circuit.
Fig. 14 of the drawings filed herewith is an elevation of a trigger arrange-
ment which can be used for breaking the circuit in the magnet coils (by the
action of a cam plate 7 fitted on the cage) at top and bottom of the hoist well
by the ascending and descending of the cage. When the cam 7 comes into
contact with the trigger it breaks the contact between the surfaces 3, 3, and when
the cam is moved away the trigger falls back into its original position and
completes the circuit again..
'T'he
By this arrangement switches are either in direct circuit with the main, or
cut off altogether and it is impossible for them to be left in any other than these
positions. The switches are brought into action slowly by means of a rope or
handle movement and the circuit is broken quickly by the action of a weight or
spring and can be applied to switches for working either direct or reversing
motors and main switches (whether single or double pole). For cage hoists the
switch may be attached either to the cage or one side of the hoist well.
cage will stop automatically at the top and bottom rooms by breaking of circuit
by roller contact, or by a cam moving triggers; or, if there be more than two
floors can be arranged so as to stop automatically at any room by movement of
a handle just before getting to the desired floor, or, by having a separate trigger
to break the circuit at each room-or a switch arrangement-can be set so as
to stop at any particular room by breaking the circuit by means of a switch
inside the room. The cage may be locked at any room at which it is stopped
by breaking the main circuit by means of a switch.
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
I claim is:-
1. An arrangement for electric cage hoists or elevators by which the motor
switch is held in circuit by the action of a pair of magnets in which the circuit

page_text: is made by means of a wire or wires which passes through two grooved pulleys
contained in a spring trigger, and by the contact of a roller (connected to a
spring trigger) with a metal surface, and the circuit in the magnet coils is broken
automatically at any room by the ascending and descending of the cage by means
of spaces between metal surfaces which cause the motor switch to be automatically
thrown out of circuit by the action of a weight substantially as described.
2. An arrangement for electric cage hoists or elevators by which the circuit
in a pair of magnet coils which control the motor switch may be broken at any
particular room by means of a switch inside such room and cause the motor
switch to be automatically thrown out of circuit when the cage comes to such
room substantially as described.
3. An arrangement for electric cage hoists or elevators by which the motor
switch is thrown into its off position by means of a weight (armature) which
is released from magnet coils (when such coils are connected in series) by the
coils being short circuited by means of metal plates and spring triggers substan-
tially as described.
4. An arrangement for electric cage hoists or elevators having a separate
spring roller trigger for each intervening room between top and bottom, any of
which may be drawn back so as to cause the circuit in the magnet coils which
hold the motor switch in circuit-to be broken automatically when the cage
comes to the particular room at which the metal surface corresponding to that
trigger is fixed substantially as described.
5. An arrangement for either cage hoists or ordinary motor work by which
the motor switch is brought into circuit by means of a rope or chain attachment,
or by means of a handle which is connected to gear wheels and has a spring
attachment to throw it out of action, and held in position by a magnet acting
upon a disc or weight, and is thrown out of circuit immediately the circuit
in the coils is broken, by means of a weight and pulley attachment to the
switch substantially as described.
7. The general construction, combination and arrangement of parts forming
the several different means for controlling the operation of switches substantially
as described and shown in the accompanying drawings.
