Improvements in Hoists for Rapid and Continuous Ascent,
Horizontal Transfer, Descent, and Horizontal Transfer to
Renew Cycle.
I ROBERT COOKE SAYER of 11 Clyde Road, Redland, Bristol Civil Engineer,
do hereby declare the nature of this invention to be as follows :—
The object of this invention is for raising and lowering in a continuous stream
either passengers or materials by incans of vehicles or cages working vertically or
diagonally and is accomplished as follows:-
Stationary uprights are fixed, between which the cages are to be worked: the
latter are prevented from turning by means of friction wheels attached to them, and
acting against the uprights. The uprights carry brackets which radiate to the
centre of their grouping, and form axles for wheels, which are able to rotate upon
them the wheels are fixed at varying heights and support channel or other shaped
iron or steel rails placed end for end and connected together and shaped so as to
form one continuous spiral of any inclination desired resting upon the wheels so as
to be prevented from lateral movement: the spirals reach from the ground level to
the top of the altitude to be reached, and winds round the outside of the uprights
and space for the enges in a circular form on plan.
The cages carry axle brackets that radiate to its centre, on plan, these have wheels
that are able to rotate upon them, they are fixed to the cages at different heights,
one at the bottom, one at the top, and others intermediate, to suit, and equally
rest upon the top surface of the spiral rail, which forms a pathway for them to
travel or rotate upon: so that the spiral carries the weight of the cages, and
as they rise the uprights prevent their turning.
The whole spiral receives a rotary motion, and travels upon the bracket wheels
of the uprights, and thus act as the thread or spiral of a large screw: as it
turns round it acts upon the bearing wheels of the cages, and they are caused
to rise or fall, vertically, or diagonally, in sympathy with its direction.
For the purpose of enabling the spiral to rotate continuously, and at the same
time to allow the cages when they reach the top to remain stationary, and not
be overwound, when the topmost supporting wheel of the cage reaches its full
height, and the cage is clear of the main uprights, the spiral changes to
horizontal rail, and at this point the top of the wheel meets a moveable shutter
or lever, and raises it, and by it raises trap doors in the spiral, at all the other cage
bearing wheels, and these are also led to similar horizontal rails, and thus arrests the
cage: the trap doors then readjust themselves by gravity, but are similarly
reopened at each revolution of the spiral. Passengers or materials are then
transhipped.
An attendant by means of a friction clutch acting against one or more of the
said horizontal rotating rails to give motion, puts into gear a platform or pair of
rails, that are run under the cage, and take against flange wheels suspended from
the bottom of the cage, and causes the cage bearing wheels to rise free from the
horizontal rails, these platform rails are drawn up an incline, and
are self
fixing, and lead to a continuous railway to the top of the down spiral, and
which conducts the cage by gravity, after the attendant by means of a clutch
similar to the above, or otherwise, has drawn out vertical parallel working guide
bars, that prevent the cage from turning after it has cleared the main uprights,
and simultaneously given an impetus to the cage. The cage runs to the top.of
he down spiral by means of similar platform rails to the above, and upon the

page_text: withdrawal of the platform rails, and simultaneous adjustment of the vertical parallel
guides the spiral carrying wheels of the cage take upon similar horizontal prolongations
of the down spiral to those of the up spiral: when loaded the cage is started upon its
down journey by means of the attendant actuating a friction clutch, acting similarly
to the above, and by which similar trap doors to the above are opened, and admits
the cage carrying wheels to the down spiral.
་
When the cage reaches the bottom, it becomes stationary in a similar way to the
above, upon horizontal rails: it is then unloaded, and by means of similar trap
doors to the above, similarly opened, the cage is lowered, by means of the lower end
of the spiral and lands upon projections that take against the bottom of the cage,
or friction wheels attached to it: these projections are connected to a rope or chain
that pass over pulleys and support counterbalance water buckets, so that when the
projections receive the weight of the cage it is automatically lowered below the
bottom of the spiral and attachments.
An incline similar in action to the one on top causes the cage to run to the
bottom of the up spiral, after the balance projections have been automatically
arrested, and an impulse given to the cage by means of a friction clutch acting
against the down spiral horizontal rail or rails to give motion.
By means of the balance buckets after they have been automatically reinforced
with more water, the cage is raised up to and upon the horizontal rails of the up
spiral by means of the bottom of the spiral, and through trap doors, when the
rotating spiral brings them round: they are then ready for loading, and are
afterwards admitted to the main up spiral by the attendant lowering trap doors,
worked similarly to the above described.
For the purpose of preventing one cage overrunning another, when the altitude
to be reached is low the friction clutches at the top and bottom worked by the
attendant are interlocked so that it is not practicable to admit more than one at a
time either going up, on top, going down, or on the bottom, but when the altitude
is great, and there are many cages travelling upon the same spiral, as many cages
as there are travelling upon one spiral, there are separate sets of horizontal_rail
stations, similar to those at the top and bottom of each spiral described, and so
arranged, that as the preceding cage advances, it actuates a lever or levers attached
to one of the uprights, and forces it over and keeps it so, until it has passed the
section between the horizontal rail stations, so that the other end of the lever or
levers, coming in contact with a projection upon the next advancing cage, causes
projections upon it to be run out from the cage, so that as the cage rises they pass
through slots in the horizontal rails, one to each, and comes in contact with trap
doors, similar to the above, in the spiral, but worked only by the cage projections,
and thus diverts all the cage bearing wheels simultaneously from the spiral to the
horizontal rails and stops the cage: thus however many cages there may be, in the
event of the topmost, or either being delayed the whole of the remainder are
successively diverted into their various horizontal rail stations and stopped, when
going either up, or down by a reversed action. When the top cage is again started
as it advances it relieves the aforesaid lever, and the projections upon the following
cage, and so on throughout the whole number, successively. When each of the
cage carrier wheels are diverted to their respective horizontal rail, and the spiral
advances in its motion, and the trap doors being carried forward beyond the
projections from the cage, the trap doors close, but as the spiral still advances, the
wheels come in contact with other trap doors fixed upon the horizontal rails, where
it intersects the spiral, and that are always kept open, so as to allow the passage of
the cage carrier wheels upon the spiral when there is no cage in front to obstruct,
but being on the horizontal the wheels meet them and closes them, and enables
then to bridge over the space, and the cage projections that opened the trap doors
vertically, now open them again by acting upon them laterally by means of a wedge
attached to them, and thus the cages remain stationary: but upon the above lever
being released, by the advance of the preceding car, and the projections being
withdrawn at the next revolution of the spiral, the spiral trap doors not being

page_text: opened by the cage projections, the wheels take again upon the spiral and the
cage rises.
Where the altitude is so great that it is not desirable. to give motion to the
spiral, it is made a fixture, and provided with cogs when required, and is supported
by outside uprights, braced together: or by brackets only supported by a building:
the cages are then made circular on plan, they are prevented from rotation by means
of rods running up their sides vertically in the form of bent pistons of small
diameter but long hydraulic rams, and so that each piston reaches from one
convolution of the spiral to another, and runs vertically with the cage, and passes
through slots in the near edge of the spiral: they are fixed on two opposite sides of
the cage: as the cage rises above the top of the spiral, they take into other similar
slots supported by the uprights, and are lowered by coming in contact with
projections, at the same point that the aforesaid parallel guides are withdrawn, by
the attendant allowing the weight of the pistons to drive the water contained in the
ram into an upper chamber. When the cage is at the top of the down spiral, the
attendant readmits the water, with additional pressure and again puts the piston
guides in position. The cages obtain their vertical motion by means of having
skeleton platforms below them fitted with bearing wheels at various heights, and
resting upon the spiral, similar to the afore described cage bearing wheels: the
axles of these wheels are produced to the centre of the platform and they are
connected together by a central vertical shaft and pinion wheels, and driven by an
independent electric, or gas motor, and as they rotate they turn all the bearing
wheels, cogged or not, and cause them to run round and up or down the spiral as
the case may be friction wheels all on the same level, are fixed between the
platform and cage, that take against a proper circular horizontal plate fixed at the
When the cage
bottom of the cage, and as these rotate they drive the cage up.
reaches the top, similar rails to the above described are drawn under the motor
platform by its own engine, these take against similar wheels to the above described
and the motor platform runs itself with the cage to the top of the down spiral,
where it descends in the same way and crosses to the up spiral again at the bottom
as above previously described. Where the gradient and diameter of the spiral,
and the sizes of the cages and platforms admit, the spiral and the braced uprights
are arranged, so that upon descending to the bottom, the platform lands upon the
rails leading to the bottom of the up spiral, and runs across direct ready to rise as
before.

ROBERT COOKE SAYER of 11 Clyde Road Redland Bristol Civil 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:-
The object is to raise and lower in a continuous cycle either passengers or
material by means of vehicles or cages working up and down vertically or diagonally,
and is accomplished as follows :-

page_text: GENERAL ARRANGEMENT OF SPIRALS.
The spirals A and B are continuous and rigidly fixed to a frame or wall C, and
reach from the lower floors FS to the upper floors FS, except the spaces
reserved at the top and bottom for traversing spirals D and D², so that above the
spiral A. the spiral D is secured to a frame DA: DA. is carried by the wheels D B,
Fig. 2 gives a part transverse section, D B are able to run upon the rails DC,
these are supported by the frame or wall C: a pressure ram E is connected to the
frame DA and is able to thrust it from above the spiral A: where the spiral D
forms a continuation of the spiral A. to above the spiral B where D forms a continua-
tion of B the frame DA and its spiral D is drawn back by the weights F, when
the pressure in the cylinder of the ram E exhausts: below the spiral B the
spiral D and frame DA are provided of similar construction to the spiral D, and
its frame DA, and this spiral similarly forms a continuation of the spirals B
and A when under either: they are similarly thrust from below B to below the
spiral A by another ram E, and drawn back by the weights F: all the spirals are
the same inclination and formed to the same radii. The spiral A is provided with
a series of taps or valves that direct power, obtained from the supply pipes J, for
thrusting up cages G that are supported by the spirals, and holding them when
desired by power brakes: the spiral B is similarly provided, but has additional taps
when gravity requires the cages to be thrust down, and when attaining too great a
speed the power opposes their progress, and the power brake stops, and holds them :
the taps are worked by tappets, actuated by governors, as the cages advance, these
are carried by the supports of the cages G. The traversing spirals D and D2 have
independent series of taps, whereby the approach of the cages G to the top and
bottom is regulated by attendants who also thrust them by the power rams E
to the other shaft and spiral, and starts them up and down.
VAGES, LT.
G represents one of any number of cages, it is supported by the axles of the
wheels GA that revolve upon the roller path HJ and also by the central ball
bearing HJ and it is kept in place by the spindle of HJ, the cage is circular on
plan, has two doors GY: G X is its floor level: on the top it carries the
guides G B and G B Fig. 1, they are fixed as shown, carried down each side of the
doors, and are long enough to be always within five notches G Z, Fig. 3, formed in
the spirals A. B, D and D², two one side and three the other, over each other, and
thus resists the tendency of the cages G to rotate: as the cage G reaches the top, the
guide GB enters fixed guides attached to the supporting frame or wall C: the
guide GB enters a rising guide G B³ formed of a pair of vertical angle irons, see
Fig. 2 that shows it in cross section. GB have friction wheels GB at the
bottom GB are able to work vertically within other guides G B attached to
the frame C: the top of the cage G meets the wheels G B and thrusts up the
guides GB with it, and also similar guides G B³ which form part of and work with
it, for the down spiral B: the guide G B passes through both the rising guides, as
the cage G advances horizontally to the spiral B, their wheels G B rotate upon its
top or roof: the guide G B reaching the rising guide passes through the first fixed
above the spiral A, and stops between the second, and the wheels GB of the
:

page_text: normally kept above the arch of the lever KC³, but are able to fill it up when the
slotted lever KA' which is attached to the spindle of the tap KA, and to which
also the lever KA is attached, and upon which they centre, so that when the
lever KA² shuts the tap KA, it lowers the levers K C³, fills up the arch of KC',
and so causes a tappet L D, to be explained to meet and actuate the levers K C
and KC whatever may be the position of the tappet L D, and thus open the
tap KC and admit power to the brake HC, through the connecting pipe KC,
simultaneously as the power to the motive spiral H B is cut off by the tap KA.: the
levers KC and K. B2 also have back arms K C' and K B for closing the taps KC
and KB by means of a tappet LD' to be explained.
GOVERNORS.
Opposite the commencement or highest part of the motive spiral H B Figs. 3, 10
and 11 the platform H has attached, and carries with it, the governor which consists
of a ball carried by the screw bolt LA: LA is provided with the spring LB
against which the.centrifugal power of the ball Lacts, and it works in the guides LC:
the bolt LA is connected to the vertical tappet lever LD, that centres at LE: so
that normally as the lever LD advances, rotating with the motive spiral H B, it
meets the lever K B2 and sends power to the motive spiral H B.
A second governor similar in construction is fixed to the bottom of the motive
spiral H B Figs. 7, 10 and 11 for closing the taps opened by the first, by means of
the tappet LD its connecting arm hinges at LDs and allows the governor ball L
to act, and the tappet LD hinges at LD and is withdrawn by the spring LD'
and allows it to pass beyond the back parts KB and KC7 of the levers KB32
and KC² of the taps KB and KC, after thrusting them back and closing the taps:
when the platform H and the ball L reach a fixed rotary speed the spring I. B is
drawn out by the centrifugal power of the ball L, and the lever LD is thrust
beyond the end projections or spandrils of the arches of the levers KB', and misses
them as the speed increases, the lever LD reaches the levers K. C², and shuts off
exhaust and admits power to the brake HC: the back arms of the levers of the
tavs are long enough to be reached by the tannet L D² in all positions.
When desired to stop a cage G at any point on the journey, or one cage over-
takes another, weighted levers M Fig. 3 centreing at Mare provided and connected
to rods Ms and the levers K A: M is so placed that an advancing cage G meets
it, raises it to the position shown dotted, and M³ depresses the lever K A², this
closes the tap K A and shuts off the power to the motive spiral H B, lowers the
levers K C³, whatever their position horizontally, and causes the tappet lever LD
of the governor Figs. 3, 4, 10 and 11 as it advances rotarily, whatever its position
by reason of being acted upon by the governor ball L to open the tap KC, and
put the brake on and so stop and hold the cage G firmly. A rocking shaft M Z
shown also in elevation at Fig. 5 carries the levers M X and M Y, M X is con-
nected to the lever K A by the spring M W and M Y is fixed at the side of the
back lever KC' of the tap KC, so that when the lever M is raised the spring M W
which is sufficiently stiff to work the lever M X and the tap KC without being
extended or compressed thrusts down the lever M X to the dotted position, carries
the lever MY with it, and thus gives room for the lever KC to be thrust back
when the tap K. C is opened, and the brake put on.
When the preceding cage G
by advancing allows the lever M to fall, or when on the journey a cage has been
stopped by an attendant lowering the rod M' by the hand lever M dotted, Fig. 3,
M not then being required, M³ is again raised, the spring M W draws up the
lever M X again, thrusts over the lever M Y, and with it the back lever K C
of the tap K˚C, and closes it to power, and opens it to exhaust, and so takes off

page_text: As the cage G reaches the top and enters upon the traversing spiral D another
lever M is provided with a slide N fixed above, Fig. 3, that is connected to, and
travels horizontally with the frame D A, so that at the first movement of the
frame DA the slide N passes below a projection M*, of the lever M, and
prevents M again falling until the frame D A has been returned to its position, and
is again ready for another cage G.
RECEIVING CAGES TOP OF "UP" SPIRAL.
To regulate the approach of the cages G to the top, see Figs. 8, and 9 which
show the taps in sectional elevation and plan, and where O is the supply pipe in
connection with the pipes J: OA a two way tap is worked by the levers O A²
and PA, and links A³, and actuated from the spindle P by means of the
key Qdotted, and leaves the entrance to the cage G clear for loading:
OA admits the power to a conical joint O B to be explained and simultaneously
closes it to the tap O C, or reverses such actions: the tap OC is opened by the
key Q, and closed by the lever OC when actuated from the "down" side
through the rods O C³, it leads to the pressure ram E and to exhaust: the male
part B of the conical joint OB with the self acting back stop tap and
hinge OD, pipe hinge link RA, that also hinges at OE, and the spring R are
attached to the frame D A, and communicate by the pipe OZ with similar taps
upon DA and similarly placed and actuated, to those upon the main spiral A on
the "up" side Figs. 8 and 9 and spiral 13 on the "down" side Figs. 9 and 9B to
be explained the male part O BS of the joint OB is provided with trunnions O B₁,
the female part is rigid. A rocking shaft S carries the arms SA for tightening
up the joint OB by acting against the trunnions 0 13: a slotted lever S C for
working the slides T and U: and a quadrant hand lever S B for actuating them
when it is passed between its full line and dotted line positions. Floors V and V2 are
attached to the frame D A and travel with it over the usual floors FS and
alternately cover the spiral shafts: V has a hole VA and slot V B in it placed so
that when in position to receive the cage G they come opposite the spindles P
and C and prevent the key entering to the spindle P in other positions. A
slide W attached to the angle iron W A, and worked by the cam W B fixed upon
the rotating platform H and rotates with it, Fig. 3, WA is drawn back by the
spring WC: the slide W is fixed above the spindle of the tap OC and between
the slide U and the travelling floor V and prevents the insertion of the key Q to
the tap OC's spindle except when the cage G is in the right position.
TRAVERSING SPIRAL ON TOP.
The other side of the frame DA is similarly provided with the hinged pipe
link RA, Fig. 94, spring R, back valve and hinge O D, and male part O B³ of
Anna fallow fomalo nart fixed at the ton of the

page_text: lever SC is passed over by the shaft S, SE is raised and prevents a slide W, to
be explained, from returning until the quadrant hand lever S B, that gives S motion
is returned from its dotted position to the full line position. The travelling floor V
is slotted above the spindle of the tap OC, and the floors V and V have notches
in them, through which projections fixed upon the levers SB pass, when the
floors V and V are in the right positions for them to be used, but not otherwise:
at the side of the spindle OC, a slide W, Fig. 9B, able to slide in the guides W² is
so fixed that when the frame D A and cage Gare thrust over to the "down"
side, the side of the cage drives in the slide W to the dotted position: so that
after the lever SB has been placed in the dotted position, and the slide U removed
clear of the tap OC, when the key Qwith its projection Q2, is inserted upon the
spindle of the tap OC, it cannot be turned toward the slide W, but it can in the
reverse direction, which sends power to the conical joint O B without affecting
the rods OC: but when the cage has been thrust clear of the slide W on its
"down" journey, and after the lever S B has been returned to the full line position,
and withdrawn the slide SE, leaving the slide U, by extending the spring UZ,
the spring WC thrusts the slide W back, and after the key Qhas been reversed
and the power cut off, its rotation is continued, without affecting the power, and
carrying the lever OC to its dotted position, draws back the rods O C³ and closes
the tap OC on the " up "side and cuts off the power from the ram E, and opens
it to exhaust: the key is then reversed and withdrawn through the floor "s
slot and so secures the tap OC being closed: when the key Q is withdrawn the
spring UZ, draws back the slide U and prevents its reinsertion until the proper
time.
The spindle of the "down" side tap OC is prolonged downwards as a vertical
rocking shaft and carries a horizontal arm having a return at the end that reaches
the lever KC of the "down" side tap KC, that is fixed upon the traversing
spiral DA, after D A and the cage G has been thrust to the "down" side over
the spiral B, so that when the tap O C, Fig. 94, is worked to thrust the
motive spirul HB and cage G down the spiral B the brake HC is simultaneously
exhausted.
TAPS FOR DOWN" SPIRAL B.
These and those of the traversing spiral on the "down" side are similar to those
for the "up" spiral A and their connecting pipes KB and KC are similarly
inclined, except when the inclination of the spirals A and B is such that gravity
requires assistance, then the tap KD, dotted in Fig. 5, for driving the motive
spiral HB downwards is added, and its connecting pipe KD³, which is inclined
with the gradient of the spiral: the tap KD is worked by the lever KD which
is formed at the back like the lever KC, except that the projection or lug is near
the spindle, and KD is worked and KD is opened by the governor tappet L D'
Figs. 7 and 10, except when starting as explained: the back lever KC of the
tap KC, and that of the tap KB are formed like the lever KC, and also opened
by the tappet LD2 which takes the lead: the front levers of all are like the
lever KC, and they are worked and the taps closed by the lever LD of the
governor, Fig. 3, whatever its position: so that normally the hinged lever L. D²
leading misses opening the taps except when gravity requires the tap KD, that
would be opened by it, but when the speed causes the governor to thrust out the
lever ID sufficiently to meet the projection or lug upon the levers K. C'
and K B' it thrusts them over, and opens the tap KC, which puts the brake on,
and the tap KB which puts on the power against the downward motion of the
motive spiral, and misses the tap KD, until the speed is so reduced that the
governor withdraws the tappet LD².
BonvPSZA
D

page_text: ment of the levers M and K A and rod M³ the action is reversed, the rod M³ is
weighted Fig. 1, and not M, and in the lowest one the power is always kept cut off
at the tap KA, so that the cage G is stopped, and the brake HC put on, and the
attendant, when the spiral D2 and frame D A are ready, is necessitated, by means
of a hand lever M Fig. 3 Sheet 1, which is interlocked with the frame DA by a
horizontal rod N, as above, to raise the rod M, admit the power by the tap KA
and take off the brake by the tap K. C, before the cage G can reach the spiral D':
its final stoppage at the floor FS is regulated as at the top of the spiral A. from
the spindle Pactuating the tap OA and sending the power to the conical joint O B,
and other parts explained, to the independent taps, similarly arranged and fixed
upon the frame D A and spiral D³, to those above on the frame and spiral DA
and D, and so spaced that the cage G is arrested in the dotted position shown, with
the brake HC full on for the passengers to alight at the floor FS, which with the
spiral shafts are covered by the slotted and holed floors V and V, that are
arranged similarly to those above at the spiral A, as well as their taps, their inter-
locking, and actuation, for traversing the spiral D' and frame D A to the bottom of
the spiral A by the ram E.
WAGE AT AND STARTING IT
BOTTOM OF THE SPIRAL A.
EROM THE
The cage G is received at the bottom of the spiral A, in the same way as at the
top of the spiral B, it thrusts in the slide W: the levers on the shaft S are worked
by the quadrant lever S B, when the notch in the floor V2 allows its motion: this
locks the slide W, by slide S E, the spindle of the tap OC is exposed by the
slide U, for the insertion of the key Q, and the joint OB is tightened up: then the
cage G is loaded: the power is turned on at the tap OC, and the brake HC
exhausted, by the lever on the vertical spindle rocking shaft of the tap OC, and
the cage G is started up the spiral A: as it clears the slide W, its spring would
return it, but it is held by the slide SE, until the key Q is reversed, and this
cannot go far enough to return the frame DA to the spiral B, until the lever S B
is reversed; which releases the joint O B, the slide SE is withdrawn, that of W
returned by its spring WC, thus allowing the key Q to be turned farther and
draw back the lever OC of the spindle of the tap O C, which meets and draws
back the rods OC', and cuts off the power and exhausts the ram E, allowing the
weights F to draw the frame DA to the bottom of the spiral B: the key Qis
then reversed and its lug withdrawn through the slot in V ready for the attendant
to repeat his cycle as above.
The working is as follows:-
The cage
having been started upon the spiral A for the "up" trip, the
governor lever L D, Fig. 3, leading opens the taps K B: the compressed air or gas
inects the cross walls of the motive spiral H B, drives it forward, and rising upon
the spiral A thrusts round the frame HH, the wheels G A rotate upon the
path HJ, the spindle of the central ball bearing H J keeps the cage G in position
and its guides G B and G B³ keep it from rotating, it then rises vertically. When
the governor tappet lever L D Fig. 7 reaches the tap K B, it meets the back
part KB' of the lever KB and closes the tap KB: when it exceeds regulation speed
the governor Fig. 3 causes its lever L D to miss the lever of the tap KB: wheu
it attains a fixed greater speed the lever L D reaches the lever of the tap KC,
opens it and puts on the brake HC upon the spiral A and all the wheels H A:
the taps K C are closed by the lever L D', Fig. 7.
When it is desired to stop a cage on the journey, or one cage overtakes another,
or it reaches the top and the frame D A. is not in position for it, the hand lever M
by an attendant, or the lever M by a rising cage G, or the lever M, by being still
held up by the rod N, respectively, lowers, or keeps down the rod M³, and cuts off
the power from the tap K B, and lowers the lever K C³, and the governor
lever L D, in any of its positious, meets the levers K C³, opens the power, through
B

page_text: the tap KC, to the brake HC: the cage G is thus stopped in each case, and
firmly held by the brake.
When the rod M³ is again raised by the reversing of the lever M, or the falling
of the weighted lever M and reopens the tap K A, power is readmitted the
spring M W draws up the lever M X, causes the lever M Y to thrust back the
lever KC, and so cuts off the power, exhausts, and takes off the brake HI C, and
restarts the cage G.
:
The frame DA with the spiral D being ready to receive the cage G, the
quadrant lever S B, Fig. 8 and 9, is placed in the dotted position, the notch in the
floor Vallowing the projection upon SB to pass through it, and so tightens up
the conical joint O B by the arms S A meeting the trunnions O B' and forcing it
in as the lever S B passes, it carries the slides T and U to their dotted positions
and thus opens a way to the spindle P and closes the entrance to the spindle of the
tap OC: by inserting the key Q upon the spindle P, the slide T and lever S B
are prevented from returning the motive spiral H B having entered upon the
traversing spiral D, the cage G's motion is regulated by the attendant with the
key who increases or diminishes its speed and stops it with the brake H C on,
the taps KC being situate relatively with the tappet L D to allow this as the
cage G stops, the rotating cam W B thrusts back the angle iron WA. and with it
the slide W and unlocks the passage to the spindle of the tap OC: as the cage is
being discharged the key Q, afice the tap OA has been closed is withdrawn, a
projection upon the key that passes below the slide T prevents its being taken
out before, or in another position: the lever S B is put back, this releases the
joint OB, again locks the spindle P by the slide T, and thrusts the slide U clear
of the spindle of the tap O C, which is then opened by the key Q, and its
lever is carried to the dotted position, and against the cud return of the
rod OC, power being admitted to the ram cylinder E and exhaust closed, and the
frame DA with the cage G in it and upon the spiral D are thrust over to the top
of the "down" spiral B, with the floors V and V and the weights F are raised :
the spiral D then forms a continuation of the spiral B: as the cage stops it meets
the slide W, thrusts it in, the lever S B, Fig. 94, is passed to its dotted position,
thus tightening up its conical joint, unlocks the spindle of the tap O C, and locks
the slide W by the slide SE: the cage is then charged: the tap O C is worked
by the same key Q, as before, which takes off the brake H C, by means of the
tap OC's vertical spindle rocking shaft and starts the cage down the spiral B, by
the tap K D, or allows gravity to do so: when the cage G clears the slide W it is
still retained by the slide S E, until the lever S B has been reversed, and so
released the joint O B and removed the slide S E, and enabled the spring WC to
return the slide W, the spring U Z being extended the key Q can be reversed,
carrying the lever O C with it which draws back the rods O C³ and cuts off the
power to and exhausts the ram E: Qis then withdrawn and the spring U Z returns
the slide U the attendant taking Q to the "up" A side finds the frame DA
ready to be locked by the shaft S for another cage, and he repeats his cycle: the
"down" cage continues its journey, being actuated more or less rapidly as required
by the taps being opened by the governor tappet L D², leading and closed by the
tappet L D following, and controled by the governors, and stopped when required
as upon the "up" spiral: arriving near the bottom the cage G is stopped, and
restarted by the attendant lowering his hand lever M' and controlls the second
stopping, if the frame DA is ready for it, by his regulating the power to the
independent taps upon the frame DA, by his key Qactuating the tap O C by its
spindle P, Figs. 8 and 9, and so stopping it with the brake HC on, the same as at
the top of the "up" spiral A: the cage is then discharged-the lever SB is thrust
back releasing the joint O B, and the key actuates the tap OC and the ram E
thrusts the frame D A and cage G to the bottom of the spiral A; the guides G B
and GB pass through the openings A A and B A and Z A in the spirals B, A
and Z; the slide W is thrust in, and the other interlocking of parts takes place as
above, the lever S B at the bottom of the "up" spiral A is then thrust to its first

the "down" spiral B: the cage G is then loaded, the key Q actuates the tap OC
putting on the power, and exhausting the brake H. C, by means of the spindle
rocking shaft of the tap O C, as above, and the cage ascends, being actuated by
the taps explained-upon reversing the tap O C, and continuing the motion of the
key the lever O C' draws over the rods OC as before and so cutting off the power
and exhausting the cylinder of the ram E, and the weights F return the frame D A
ready for another cage.
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
1st. The arrangement of fixed main spiral inclines upon which vehicles or cages
are caused to ascend and descend, together with the manner in which the cages
are received at the top and bottom of the main spirals upon shorter traversing
spirals, and the transfer of such shorter spirals, with the cage, from one main spiral
to another at the top and bottom, whereby a continuous cycle of any number of
cages may be maintained. Also the use of one main fixed spiral only upon which
cages are sent up and down substantially as described.
2nd. The arrangement of the cages, and their guides which pass vertically
through notches in the spirals and keep them from turning, while the platforms
which give them vertical motion, receive rotary motion, through a jointed motive
spiral formed of longitudinal and cross walls, and being the same inclination and
curvature as the main spirals upon which its lower chambers or plates slide, being
thrust down by springs also a brake of the same or less length than the motive
spiral, having flexible sides and top which are retained by the walls of the motive
spiral, and a metal base plate which can be thrust down against the main spiral,
and which is retained in its position by lugs attached to the motive spiral entering
notches in the plate: also for supplying the motive and brake spirals with power of
compressed air or gas for propelling them, or arresting and holding them with the
brake and the arrangement whereby the brake acts upon the wheels that carry
the frame and cage, through metal plates suspended from the spindles of the
wheels. each of which, as well as the base plate, are drawn back by springs sub-
stantially as described.
3rd. The arrangement of the taps fixed to the main and traversing spirals for
supplying the power to the motive spiral, and mode of working them by tappets,
attached to the rotating motive spiral and so regulating the power as to give
motion to the cages: or to arrest them when overtaking another cage, by means of
a preceeding cage, at fixed points on the journey, cutting off the power from a
following cage, and putting the brake on, by coming in contact with and raising a
weighted lever, and until it has passed on, the lever closes one or more stop taps in
the power supply pipe, through a vertical rod, but when it has passed, the weighted
lever, falling, reopens the stop tap to power and simultaneously exhausts and takes
off the brake by a rocking shaft working a lever that reverses its tap. And also
that when a cage reaches nearly the top or bottom of the main spirals, and when
the traversing spiral is not ready to receive it, it is similarly arrested, by means of
the traversing spiral frame, having attached a sliding bar, that keeps the last
weighted lever up until the traversing spiral has been returned and is in a position
to receive the following cage: and also that when desired a cage is stopped at a
fixed point on the journey by means of a hand lever actuating the aforesaid vertical
rod and otherwise stopping the cage as before and restarting it by reversing the
hand lever and also that when the power has been readmitted to the following
cages motive spiral, in each case it then advances, substantially as described.
4th. The arrangement of the governors which are worked by the rotating
platforms of the cages and closes the power and puts the brake on, and when
required admits the power to oppose the advance of the motive spiral at

page_text: predetermined speeds: by the centrifugal power of a ball, created by its being
attached to the rotating motive spiral of the cage, at a high part and thus drawing
out a spring and adjusting a lever which opens the taps and a second attached
to the motive spiral at a low part and similarly closes them substantially as
described.

5th. The arrangement of the taps and valves at the top and bottom of the main
spirals, and upon the traversing spirals, where the "up" side are similar to those for the
up" main spiral: and the "down" side are similar to those for the "down" main
spiral for regulating the power to the motive spirals of the cages for stopping and
starting them, and the pressure rams that thrust them over to the other main spiral,
and which when exhausted allows weights to draw them back for which the
power is received through a conical joint, which connects the fixed taps to the
traversing taps, that are actuated by levers attached to a rocking shaft, which
obtains motion from a main hand lever, that also actuates slides, for covering the
tap spindles, so that together with the travelling floors, which are attached to the
frame of the traversing spiral, and which are so provided with holes and slots, through
which a key carrying a cam, must pass for working the taps, that they cannot be
worked until
(a) the traversing spiral is in place and
(6) the conical joint of the pipes is tightened up :
and the taps which actuate the rams cannot be worked until,
(n) the other tope
are closed
(b) the conical joint released and
the cage is in the right position :
:
it is then worked by the key which cannot be reversed in its action for returning
the traversing spiral, until the cage has vertically cleared it, and the conical joint
is released and when it is reversed, it cuts off the power, and exhausts the ram
cylinder, at the other spiral, by drawing back connecting rods and as the frame
returns for another cage the key is withdrawn, and the parts are left locked rendy
to repeat the cycle substantially as described.
