AUTOMATICALLY CONTROLLED AMUSEMENT RIDE James Howard' Hansen INVENTOR.

L1 BY @4m F1 Q 7. g'gen United States Patent 3,321,203 AUTOMATIICALLY CUNTRLLIED AMUSEMEN'I INDE .lames Howard Hansen, Gladstone, Oreg. (503 Palo Alto Ave., Mountain View, Calif. 94049) Filed Nov. 12, 1963, Ser. No. 322,896 7 Ciaims. (Ci. 27238) This invention relates to amusement rides, and more particularly to a multiple carrier amusement ride which is capable of operation through cycles for each carriage without the presence of an operator.

In amusement rides of the type wherein a plurality of carriers are moved through a common circuitous path, it has been necessary heretofore that an operator be in attendance at all times to control the stopping of each c-arriage individually at a landing, to permit participants to enter or leave each carriage. Typical of such lamusement rides are the Well-known Ferris wheel and similar verti cally rotatable multi-carriage devices, as well as many horizontally rotatable devices of the type, for example, wherein a plurality of radial arms each supports at each extremity a miniature car, airplane, or other carriage.

Although the cost of operation of such operator-attended devices is not excessive when the device is associated with many others in a large midway or other concentrated area, the cost of operation becomes prohibitive when the ride is not associated with others and is located in a relatively isolated area. Typical of such application is the provision of a ride in the location of `a super market, service station, shopping center, city park, bowling alley, and various other sites.

It is the principal object of the present invention to provide an amusement ride of the class described in which operational control of each carriage is effected without the personal attendance of an operator.

Another important object of this invention is the provision of an amusement ride of the class described in which the operational control of each carriage is effected automatically by the proper sequential actions of the participants.

Still another important object of the present invention is the provision of an amusement ride of the class described which is characterized by fail-safe operation in that any improper action of any participant functions to stop the ride.

A further important object of this invention is the provision of an `amusement ride of `the class described in which the automatic control may be interrupted manually by a participant or by a person associated with the participant but not actively participating in the ride.

A still further important object of the present invention is the provision of an amusement ride of the class described which is of relatively simplified construction for economical manufacture and which is capable of extended operation with a minimum of maintenance.

The foregoing and other objects and advantages of this invention will appear from the following detailed description, taken in connection with the accompanying drawings in which:

FIG. 1 is a perspective View, partially broken away, of an `amusement ridev of the Ferris wheel type, embodying the features of the present invention;

FIG. 2 is a fragmentary front elevation showing a pivot mounting for the safety bar associated with each seat unit of the ride illustarted in FIG. l;

FIG. 3 is a fragmentary front elevation illustrating locking mechanism associated with the safety bar of each seat unit of the ride illustrated in FIG. l;

FIG. 4 is a sectional View taken along the line 4-4 in FIG. 1; and

3,321,203 Patented May 23, 1967 FIGS. 5, 6 and 7 are schematic diagrams of an electrical system for the control of the ride illustrated in FIG. 1, the circuitry of each ligure being in continuity with the others.

In the Ferris wheel type ride shown in FIG. 1, and which is illustrated primarily for the purpose of describing the fundamental concept of the present invention, there is provided a framework structure which includes the horizontal base members 10 and the laterally spaced vertical truss members 12. The truss members support, at their upper ends in appropriate bearings, the main drive shaft 14 which is coupled in any convenient manner to the output shaft of an electric drive lmotor 16 located in any position desired.

Secured to the main shaft for rotation therewith is a wheel structure. In the embodiment illustrated, laterally spaced pairs of mounting discs 18 are secured to the shaft 14, and each supports a plurality of radially projecting, elongated support arm structures 20. These are arranged in laterally spaced pairs, with each pair pivotally supporting between them, as by means of the pivot shafts 22, a seat unit adapted to support a participant of the ride. The embodiment illustrated provides three such seat units S1, S2, and S3, although it will be understood that the number of units may be varied as desired.

Transparent side walls (not shown) may extend from the opposite sides of each seat unit, if desired, to insure against possible injury of a participant by contact with the arm structures 20.

Each seat unit is provided with a safety bar 24 which is mounted pivotally at one end on the seat unit for swinging movement between an open position which exposes the seat unit for entry and exit by a p-articipant, and -a closed position projecting across the seat and the lap of the participant, for confining the participant in the seat. ln the embodiment illustrated in FIG. 2, the safety bar is mounted at one end on the seat unit S by means of the pivot pin 26 which extends through the bar and is supported at its opposite ends in spaced brackets 28 secured to the outwardly projecting iiange of the seat unit. Since, in the embodiment illustrated, it is desirable that the safety bar swing automatically to open position when unlocked, a coil spring 3l) is looped about the pivot pin and is secured at one end to the bar and at the opposite end to one of the brackets. This connection is made in such manner that the spring is in tension when the bar is in closed position, thereby urging the bar to the open position. A stop pin 32 extends between the brackets to limit opening of the safety bar to a position substantially parallel to the side Walls of the seat unit,

The opposite end of the safety bar is adapted to be locked releasably to the seat unit when in closed position. In the embodiment illustrated in FIG. 3, the end of the bar opposite the pivot support 26 is provided with a recess 34 adapted to receive a latch pin 36 which, as illustrated, is formed by the extending armature of an electric solenoid 3S mounted on the seat unit. In the closed position of the safety bar, the latter engages the actuating pin 40 of a microswitch 42 for locking `the latch pin, as described in detail hereinafter.

Each seat unit also is provided with another electric switch 44, herein referred to as a participant interrupt switch, the actuator button 46 of which is disposed for convenient access to the participant in the seat unit. As explained more fully hereinafter, this switch serves to permit the participant to stop the ride if he Wishes to exit before the number of rotations allotted to him have `been completed.

Each seat unit also is provided with a seat switch which is actuated when the participant has seated himself within the unit. Conveniently the seat switch is provided by means of a seat pad switch 4S having an internal construction which includes switch contacts that are brought together when Weight is placed upon the pad. Pad constructions of this type are widely used, lfor example, as entrance and exit mats in supermarkets and other commercial establishments to effect automatic opening of doors. The function of the seat switch on each unit is. explained in detail hereinafter.

The ride structure described hereinbefore is enclosed by a peripheral wall Sil which is open only at one end for entrance and exit. This open end normally is closed by an entrance door 52 and an exit door 54, separated laterally from each other and each mounted for independently controlled swinging movement. Thus, the entrance door is mounted for swinging movement on the housing 56 secured to one end of the peripheral wall. This housing encloses an electric reversible motor S8 (FIG. 7) which functions to open and close the door. The housing also encloses an electric switch 6i) (FIG. 7) which, as explained more fully hereinafter, functions to; stop the motor S8 when the door 52 has been fully opened.

Similarly, the exit door 54 is mounted for swinging movement on the housing 62 secured to the opposite side of the peripheral wall 50. This housing also encloses an electric reversible drive motor 64 and direction control switch 66 (FIG. 7).

A hollow center post 68 between the doors houses the electric solenoids 70 and 72 associated with the entrance and exit doors 52 and 54, respectively. Each solenoid has a retractable latch armature associated with a catch on the door, for releasably locking the latter in closed position. The post also supports the latch solenoid switches '74 and '76 associated with the solenoid 70 and '72, respectively, for controlling operation of the latter, as explained in detail hereinafter.

A base platform covers an area under the entrance and exit doors, and laterally spaced guide rails 78 define entrance and exit passageways associated with the doors. An electric switch mat 80 is supported on the platform within the entrance passageway on the outer side of the entrance door. A similar electric switch mat 82 is supported on the platform within the entrance passageway on the inner side of the door. In similar manner, electric switch mats S4 and 86 are supported upon the platform within the exit passageway on the inner and outer sides respectively, of the exit door.

An additional electric switch mat 83 is supported upon a platform which extends inwardly from the pads 82, 84 to a position at which a participant may enter a seat unit when the latter is in proper position for entry, as explained more fully hereinafter.

It will become apparent hereafter that the electric switch mats serve to control the sequential operations of the amusement ride, in response to the weight of participants as they move from one mat to another.

In the preferred embodiment illustrated, there is also provided a plurality of electric switches mounted on the peripheral wall 50 adjacent the exit door 54 and at an elevation above the ground sufficient to prevent actuation by small children. These switches R1, R2, R3, hereinafter referred to as remote interrupt switches, are associated one with each of the chair units S1, S2 and S3, respectively, and, as explained in detail hereinafter, are intended for use by a childs mother or other adult companion who awaits outside the wall 50', when it is desired to stop the ride to have the child leave the ride before the allotted time has been completed.

The association between each of the remote interrupt switches and its corresponding seat unit may be identified by various means. For example, each switch may carry a numeral corresponding to a numeral located on the corresponding seat unit at a clearly visible location. Alternatively, or in addition, each switch and corresponding seat unit may be provided in matching color with each set differing in color from the others.

Electrical connections between the relatively rotatable components of the ride assembly may be provided in any desired manner. For example, a multiple collector ring assembly @d (FIG. 5) may be mounted for rotation with the main shaft 1d, with each ring having an associated brush contact, indicated by the arrow heads, supported in fixed position on the adjacent vertical truss member. Each collector ring of the assembly is, in turn, connected electrically to an associated ring of an assembly 92 secured to each support arm 20 concentric with the associated pivot shaft 22. Each of these latter rings has an associated brush contact mounted on the associated seat unit concentric with its pivot shaft. These last named brushes are `connected electrically to the several switches associated with each seat unit, namely the safety bar latch solenoid 38, the safety bar lock sensing microswitch 42, the participant interrupt switch d4 and the seat pad switch d8.

In FIG. 5 the collector ring assembly 9d is shown to include ve rings, each associated with one of the five rings of the assembly 92 on one of the seat units. Since there are three seat units illustrated in FIG. l, it will be understood that three assemblies 9G will be provided or one assembly 9@ will be provided with a sufficient number of rings to accommodate all three ring assemblies 92.

Referring now to FIGS. 5-7 of the drawings, the electrical circuitry illustrated therein is best described in connection with the operation of the ride, as follows:

First, it is to be understood that the electrical circuitry illustrated in FIG. 5 is associated with one of the seat units, for example seat unit S1, and that identical circuitry is provided for each of the other seat units S2 and S3. Thus, whereas the circuitry of FIG. 5 is associated with the remaining circuitry by the interconnection of common conductors extending between FIGS. 5, 6 and 7, the circuits associated with seat units S2 and S3 are associated With the remaining circuitry by connection to the common conductors terminating at the left hand side of FIG. 7. Thus, duplication of the circuitry in FIG. 5 for seat units S2 and S3 is not made herein, but rather the components illustrated in FIG. 5 are identified hereinatfer in relation to the various seat units. i

Second, in FIG. 6 there is shown a ganged switch 94 which, in the position illustrated, connects the entrance mat switch into the operating circuit. This swit-ch may be moved to the alternate position to connect into the operating circuit a token or coin operated switch 96 which would replace the function of the mat switch 80, as will be apparent.

Since the following description relates to automatic operation of the system, the manual-automatic switch 98 (FIG. 6) is shown in automatic position. In manual position, with switch 98 open, the seat assembly rotates continuously, as for display, since mat switch 80 is disconnected from the control circuit.

Assuming that the supply lines L1 and L2 have been connected to an appropriate source of electrical supply, the Ferris wheel structure thus is activated to continuous rotation by virtue of the driving of the main shaft 14 by the drive motor 16. This motor is activated by cornpletion of its electric circuit through closure of the contact associated with the motor control relay 100 (FIG. 7). Closure of this contact is effected by activation of the relay by completion of its electric circuit from supply line L1, through said relay and conductor 102, through the normally closed contact D of the inactive relay 104 associated with seat unit S3, (not shown, but identical to FIG. 5), by connection of conductor 102 in FIG. 7 to conductor in FIG. 5, thence through normally closed contact C of relay 166 also associated with seat unit S3, thence through conductor 112 in FIG. 5 and its connected conductor 108 in FIG. 7 to the normally closed contact D of inactive relay ldd associated with seat unit S2 (not shown, but identical to FIG. 5), by connection of condoctor 168 in FIG. 7 to conductor 11) in FIG. 5, through .5 normally closed contact C ot relay 106 associated with seat unit S2, thence through conductor 112 in FIG. 5 and its connected conductor 110 in FIG. 7, through the same conductor 110 in FIG. 6 to said conductor 110 in FIG. 5 to normally closed contact D of relay 104 associated with Seat unit S1 (FIG. 5), through normally closed contact C of inactive relay 106 associated with seat unit S1, thence through conductor 112 and normally closed contact B of inactive relay 114 (FIG. 6), through normally closed contact B of inactive relay 116 and normally closed contact B of inactive relay 118, to the other supply line L2.

Let it be further assumed that seat unit S1 is unoccupied when a child approaches the ride and steps upon the entrance mat switch 80 outside the entrance door 52. Consequent closure of this switch completes an electric circuit from supply line L2 through the closed manual-automatic switch 98 and said mat switch S0 and conductor 120, through normally closed contact G of inactive relay 104 associated `with seat unit S1 (and any other unoccupied seat unit), through conductor 122 and relay 124 to the other supply line L1. Consequently activation of relay 124 eifects closure of its associated -contacts from the open positions illustrated in FIG. 6.

A cam member 126 (FIG. 7) is secured to the main shaft 14 for rotation therewith, to ettect sequential operation of a plurality of electric switches. When the cam member rotates to the position at which it engages and closes the mechanically coupled switches 128 and 130, and electric circuit is completed from supply line L2 through the now closed contact C oi; activated relay 124 (FIG. 6) through conductor 132 and the normally closed contact E of inactive relay 104 (FIG. 5), through conductor 134 (FIGS. 6-7) and the closed switch 128, through conductor 136 (FIGS. 7-6) and relay 106 (FIG. to the other supply line L1. Activation of the relay 106 effects closure ot its associated contacts A and B and opening of contact C, and the closure of its associated Contact B forms 'a holding circuit for the relay through the normally closed contact E of inactive relay 104 and the closed contact C of activated relay 124.

Activation of relay 106 effects opening of its associated contact C, thereby breaking the electric circuit of the drive motor relay 1110 and consequent stopping of the drive motor 16.

However, because of the inertia of the rotating wheel structure, the main shaft 14 continues to rotate for a short distance, sufficient to rotate the second cam member 126' into closing engagement with switch 138. Closure of this switch results in completion of an electric circuit from supply line L2, through said closed switch 138 and conductor 140 (FIG. 7-6), through the now closed contact A of activated relay 106, through relay 142 to the other supply line L1. This relay 1412, which is oi the delayed ybreak type, is maintained activated by a holding circuit which is completed rby closure of its associated contact A.

Closure of switch 138 also effects activation of relay 144 which is arranged in parallel with delay relay 142. Relay 144 is maintained activated -by the same holding circuit for relay 142.

Activation of relay 144 eiects closure of its associated contacts from the open positions illustrated, and closure of contact D completes an electric circuit from supply line L2 through closed Contact D of activated relay 124, through conductor 146 and the normally closed contact F of inactive relay 104, through the closed contact D of active relay 144 and conductor 148, through relay 150 to the other supply line L1. The contacts A and B associated 'with this relay 150 thus close and open, respectively, and closure of said contact A completes an electric circuit from supply line L2 through said contact and conductor 152, through entrance door switch 60 and the winding 154 of the entrance door drive motor 58 to the other supply line L1.

Simultaneously with the activation of the entrance door drive motor, the electric circuit of the entrance door latch solenoid 70 is completed from .supply line L1 through the solenoid and the normally closed contact 156 of the multiple entrance door switch 74, through conductor 148 (FIGS. 7-6-5) and the closed contact D of activated relay 144, then-ce through the normally closed contact F of inactive relay 104, through conductor 146 and closed contact D of activated relay 124, to the other supply line L2. The latch is thus retracted, unlocking the entrance door for movement to its open posi-tion, by the drive motor 58. A holding circuit for the latch solenoid is provided by closure of the contact 158 of entrance door switch 74, upon the start of opening movement Iol? the door.

When the entrance door reaches its fully open position, permitting the child to pass through the opening, the door engages `and opens the door switch 60, thereby breaking the electric circuit of the drive motor S8 and maintaining the door in open position.

The child then steps through the entrance door opening and onto the interior entrance mat switch 82, thereby completing the circuit of relay 118. The contacts A and B associated with this relay thus close and open, respectively, closure of contact A thus lay-passing contact D of relay 124, whereby to maintain the entrance door drive motor deactivated and the door open.

The child then steps from the interior entrance mat switch 82 onto the landing mat switch 88, to progress toward the rotary seat assembly. Closure of the landing mat switch 88 completes lthe electric circuit of relay 116, effecting closure of its associated contacts A, D and E and opening of its contacts B and C. Closure of Contact E `of activated relay 116 completes the electric circuit of relay 104 from supply line L1, through said relay and the closed contact B of activated relay 144, thence through conductor 160 and the now closed contact E ot activated relay 116, to the other supply lin-e L2.

Activation of relay 164 results in the closing of its associated contacts A, B and C and opening of its contacts D, E, F and G, the opening of contact G thus breaking the electric circuit of relay 124. Upon opening of contact D of relay 12d the electric circuit of the entrance gate motor Sti is broken, thereby maintaining the gate closed. This prevents a succeeding child from initiating a new cycle at this time.

Activation of relay 10i also effects opening of the associated contact F, thereby breaking the electric circuit of relay 150. In this regard it is to be recalled that relay had been maintained activated by the closed contact A associated with relay 11S, when the child was standing on the interior entrance mat switch 82, but that this circuit was broken when the child stepped from said mat switch onto the landing approach mat switch 88.

Deactivation of relay 150 results in return of its associated contacts to the positions illustra-ted, wherein closure of contact B completes the electric circuit of the reverse winding 162 ot the entrance door drive motor 58, from line L2 through said closed contact B and conductor 164, thence through the now closed contact 166 of the door switch 74, through the reverse winding 162 to the other supply line L1. Accordingly, the entrance door 52 is driven to its closed position, whereupon the contacts of the door switch 74 are returned to the positions illustrated, the lat-ch solenoid 70 is deenergized and the latch moved to locking position.

The child now steps from the landing area of the mat switch 88 at which heat unit S1 has been stopped in proper position for entry, and sits upon the seat pad switch 48 (FIG. 4). In stepping from the landing mat switch 8S the latter opens and deenergizes relay 116, thus returning the associated contacts to the positions illustrated. Although the associated contact A has opened, relay 104 is maintained energized by the by-pass circuit extending from supply line L1 through said relay and its closed contact B, thence through conductor 168 and the normally closed contact B of inactive relay 170, to the other supply line L2.

Closure of the seat pad switch 48 completes an electric circuit from supply line L2 through the associated collector rings and said seat pad switch, through relay 172 to the other supply line L1, whereupon its associated contacts close.

The child now reaches up and swings the safety bar 24 downward across his lap, whereupon the bar engages and closes the safety bar switch 42. This switch thus completes an electric circuit which extends from supply line L2, through the associated collector rings and the safety bar switch, through the normally closed contact C of inactive relay 174, thence through the closed contact C of active relay 172, through delay relay 176 to the other supply line L1. Upon activation of relay 176, the electric circuit of the drive motor control relay 10i) is again cornpleted, this time through the contacts D and C of the respective relays 104 and 106 associated with seat Aunits S3 and S2, thence through conductor 110 and the closed contact A of activated relay 176, through the closed contact A `of activated relay 172 and the closed contact C of inactive relay 106 associated with seat unit S1, thence through conductor 112 and the closed contacts B of 4inactive relays 114, 116 and 118, to the other supply line L2.

Further, when the safety fbar 24 closes the switch 42 to activate relay 176, the associated contact C opens the electric circuit of the safety bar latch solenoid 38 which thereupon extends `its armature 36 into locking engagement with the safety bar.

The main drive motor 16 then rotates the seat unit assembly. During each revolution of the assembly the cam member 126 engages 4and closes the shaft switch 130 momentarily to complete an electric circuit from supply L2 through said switch and conductor 178 (FIGS. 7-6-5) through closed contact A `of relay 104 and conductor 180 (FIGS. 5-6-7) to an electric pulse counter device 182 of any well-known type, to the other supply line L1. After a preset number of counted pulses, an associa-ted counter switch 182 closes to complete an electric circuit from supply line L2 through said switch and conductor 184, thence through normally closed contact I of deenergized relay 186 (FIG. 6), through conductor 188 and relay 174 to the other supply line L1. The contacts A and B associated with this relay 174 thus close and contact C opens, the associated contact A forming a holding circuit which bypasses the counter switch 182.

Upon closu-re of contact B of relay 174 an electric circuit is completed from supply line L1 through relay 106 and conductor 136, through switch 128 (which is closed momentarily by the cam member 126), thence through conductor 134 and the closed contact B of active relay 174, thence through conductor 190 and the normally closed contact J of inactive relay 186, to supply line L2. Activation of relay 106 results in the opening of contact C breaking the electric circuit of the motor control relay 100 and stopping the drive motor 16. The closing of contact A associated with activated relay 106 completes the electric circuit of relays 142 and 144, when the cam member 126 rotates to a position closing switch 138. Activation of relay 142 effects opening of its associated contact B which, in turn, opens the electric circuit of relay 176, closing its associated contact C and activating the safety bar latch solenoid 38 to retraction. The safety bar 24 thus swings outward away from the seat unit S1, under the influence of the spring 30, giving evidence to the child that his ride has been completed and he is required to leave.

The child then steps from the seat unit S1, onto the landing mat switch 88, and walks onto the interior exit mat switch 84. Closure of this switch completes the electric circuit of relay 114 to close the associated contact A and complete the electric circuit of relay 192.

Activation of relay 192 effects closure of its associated contact A, completing an electric circuit from supply line L2 through said closed contact and conductor 194 (FIGS. 6-7), thence through the closed exit door switch 66 and the exit door drive motor winding 196 to supply line L1. Simultaneously, closure of contact A of activated relay 114 completes the electric circuit from supply line L2 through said closed contact and conductor 198 and the closed contact 200 of the exit door switch 76, through theexit door latch solenoid 72 to the supply line L1. Activation of this solenoid causes retraction of its latch armature to unlock the exit door 54. The latch solenoid is maintained activated upon closure of contact 202 of switch 76 when the exit door starts to open.

When the drive motor 64 has opened the exit door to its fully open position, the door engages and opens the door switch 66 to stop the motor 64. The child then steps through the exit door opening onto the exterior exit mat switch 86, thereby completing the electric circuit from supply line L2, through said mat switch and the closed contact C of deenerziged relays 114 and 116, thence through conductor 204 and the closed contact C of activated relay 104, through closed contact C of activated relay 144, through conductor 206 (FIGS. 5-6) and relay 208, to the other supply line L1. Activation of relay 208 effects closure of its associated contacts.

When the child moved from the interior exit mat switch 84, deactivating relay 114, opening of the associated contact A caused deactivation of relay 192 and consequent closing of its associated contact B, thereby completing the electric circuit of the reverse winding 210 of the exit door drive motor 64 from L1 through said winding, thence through the now closed contact 212 of door switch 76 and conductor 214, through closed contact B of relay 192 to L2. The exit door 54 thus returns to closed position behind the child who since has left the outer exit mat switch.

Upon activation of relay 208 when the child closed exit mat switch 86, closure of associated contact A effects completion of the electric circuit from supply line L2 through said contact and conductor 216, through the now closed contact 218 of door switch 76, thence through conductor 220 and parallel relays 170 and 186 to supply line L1.

Upon activation of relay 170, its associated contact B opens to break the electric circuit of relay 104, returning its associated contacts to the positions illustrated wherein the closure of contact G indicates that seat unit S1 is no longer occupied. Additionally, closure of contact A associated with activated relay 170, completes an electric circuit from supply line L2 through said closed contact and conductor 222, through the closed contact A of activated relay 144, thence through conductor 224 and the pulse counter 182 to the other supply line L1, returning the counter to zero for the next cycle.

It will be understood that the foregoing sequence will repeat for each subsequent child in turn, at any point in the cycle of operation of the seat unit S1, for any seat unit that is or becomes unoccupied before the cycle for seat unit S1 has been completed.

However, subsequent children must wait for the completion of one cycle of operation for each seat unit, determined by the associated counter mechanism, before a subsequent cycle can be started. This is evident since the closure of the exterior entrance mat switch has no eifect until relay 104 becomes deenergized to effect closure of its associated contact G.

Moreover, activation of the drive motor 16 cannot be eiected if, for any reason, someone is standing upon any of the interior mat switches 82, 88 or S4. Thus, if an adult leads a child through the entrance door and seats him in the seat unit that has stopped at the proper landing position, the companion rnust leave through the exit door before the ride may commence. Similarly, if a child leaves a seat unit upon completion of his ride, he must leave through the exit door before the ride can again be activated. This insures against a child taking more than one ride at a time. Walls may be provided to confine switch mats, i.e. to prevent them from stepping off the interior mats and remaining inside the wall 50.

In the event a child desires to leave the ride before the allotted revolutions have been completed, he may depress the participant interrupt switch 44 on his seat unit, to complete the electric circuit of relay 174 and thereby elect stopping of the ride When his seat unit comes to proper position at the landing mat switch, as determined by the activation of the switch 128 by cam member 126.

In similar manner a companion to the child may stop the ride before normal completion, by pushing the remote interrupt switch corresponding to the seat unit.

In the event a child attempts to climb out of a seat unit, and thus lifts his weight from the seat pad switch 48, relay 172 will become deenergized thus opening its associated contact A to break the electric circuit of the motor control relay 100 and shutting down the ride.

It will `be apparent that if, for example, two of the three seat units are occupied when another child steps upon the outer entrance mat switch 80, the rotary unit will continue to rotate the occupied seat units past the landing position, because of the fact that contact G of relay 104 associated with those occupied seat units will be open, and vonly the unoccupied seat unit will have its associated relay 104 deenergized and its contact G closed, ready to effect activation of relay 124.

It will be apparent from the foregoing that the arrangement described is readily adaptable for use with amusement rides of various types in which a plurality of seat units or other forms of participant carriers are rotated or otherwise moved through a circuitous path.

It will be further apparent, to those skilled in the art, that various changes may be made in the structural and electrical arrangements described hereinbefore, without departing from the spirit of this invention and the scope of the appended claims.

Having now described my invention and the manner in which it may be used, what I claim as new and desire to secure by Letters Patent is:

1. An amusement ride comprising:

(a) Ia plurality of carriers,

(b) driven means interconnecting the carriers for moving the latter through a circuitous path past a landing station,
