Application December 13, 1937, Serial No. 179,564
This invention relates to amusement devices suitable for erecting in amusement parks for the enjoyment of those who desire to be moved with others beside them swiftly and erratically.
It is also an aim to provide in combination the advantages of a scenic railway and a gyratory conveyance, with certain novel features contrib- "uting materially to the element of surprise and uncertainty as to the movements of the convey- 1o ance.
It is an important aim to present a device of the character described in which cars may be caused to move the passengers through a meandering course by the use of extremely simple It is a particular aim to enable the use of a simple rotary mounting for the car proper in which the patrons are carried, and a simple drive for rotating the car without the liability of producing an dizziness, and in fact, without actually moving the patrons in a circular path, due to the novel components of motion produced in my apparatus. Additional objects, advantages and features of invention reside in the construction, arrangegg ment and combination of parts involved in the embodiment of my invention, as will appear from the following description and accompanying drawing, wherein Figure 1 is a plan of a complete railway em- 30 bodying my invention.
Figure 2 is a plan of a car unit with parts removed.
Figure 3 is an elevation of one of the units partly in section, and showing the track in sec- 35 tion.-
Figure 4 is an enlarged fragmentary section of the mounting of one of the cars on its truck. There is illustrated a track frame-work l3 extending over a suitable sinuous course, which in 40 the present instance is similar to the figure 8 but may be varied in plan as desired. It supports a track consisting of two parallel rails ll throughout the course. Any usual station structures, not shown, may be provided where con- ..45 venient, in accordance with approved practices.
It is an advantage of the invention that I am able to use an ordinary railway rail of standard proportions with a novel manner of mounting and coordination with a carriage and wheel 50 mounting. The frame-work Ill includes a suitable number of truss members l2 connected by cross members I3 in. rigid mutual relation. The truss members extend above the cross members as shown and have bracket fittings i l thereon,
56 each having a block part I5 so shaped at the inner side so that its upper part will wedge between the head IB and flange ll of the rail at one side, a groove l8 being formed in the block to receive the flange and its lower side being adapted to support the base of the rail.
A bolt is engaged through the block and stem of the rail whereby the latter is held snugly to the bracket in rigid relation to the frame-work.
On the track there are mounted a number of trucks l9, each consisting of a normally plani- 10 form rectangular body plate 20, parallel to the plane of the rails, formed of resilient steel sheet approximately inch thick. At each corner of this plate there are provided leg elements 2| including clamp portions 22 in which the edge '15 portions of the plate are removably secured. Mounted in these legs there are two axles 23, carrying top wheels 24 at their outer ends outwardly of the brackets and resting on the heads of the rails, while at the lower ends of the legs 20 there are mounted wiper rollers 26 engaging against the under sides of the inner foot flanges of the rails.
The trucks are moved on the track by means of an endless chain 21 operated in a grooved guide 28 located centrally of the track, the guide having suitably spaced pulleys 3U cooperable with the chain for guidance of the chain. A driving device 3|, which may include any suitable power means, is provided, from which there 30 is extended a chain 29 which is operatively connected with a sprocket 3|, the latter being in driving engagement with the chain 21.
The trucks are connected in a train of a suitable number of trucks connected by link couplings 32 suitably pivoted on the plates 20. One or more of the trucks may be connected to the chain 21 by means of a connection such as shown at 33.
On each truck there is mounted a circular car 40 body 34, consisting of a central circular pit 35 including a floor plate 36, and an outwardly extended nearly annular seat 31, substantially 0- shaped and concentric with the pit, the inner edge of the seat being approximately at the upper boundary of the pit. A back 38 is provided at the outer edge of the seat consisting of a plate or wall linearly coextensive with the seat, and completing the upper part of the body. Suitable cushioning may be provided on the seat and back. As a convenient framing for the car body, a series of frame pieces 39 are provided, substantially W-shaped, each including a short arm 40 secured to the floor plate 36, a vertical stud 4| to the outer side of which the wall of the pit is attached, a horizontal arm 42 upon which the seat is built, and a vertical arm 43 carrying the outer Wall of the back 38.
On the under side of the floor there is secured a concentric turntable plate 44, while upon the plate there is secured a similar plate 45. A stud shaft 46 is fixed in the latter plate and engaged revolubly through the plate 44, being provided with a retaining flange at its upper part to retain the car body from lifting away from the truck.
While any convenient or practicable number of cars may be connected in a train, and more than one train may be installed on the track, in the present instance, one train 41 is shown, consisting of five cars. On the bed plate 20 of the middle car a laterally extended horizontal bracket plate is mounted fixedly, having an electric motor 48 mounted on its outer part, and carrying a wiper arm 49 making contact with a third rail conductor 50 spaced suitably from the track. There are shown in the present instance, two of the third rails of short length, located at longitudinally spaced parts of the track at the inner sides of the curves at the ends of the figure 8 circuit, so that the motor will be energized for short periods during the travel of the train around the course. More or fewer of the rails 50 may be provided, if desired. Inwardly of the motor 48 on the truck there is mounted a large bevel gear 5! on a vertical axis, and meshed with this gear there is a pinion 52 carried by the shaft of the motor 48. The gear 5| carries a horizontal sprocket 53 with which there is engaged an endless chain 54 in opposite directions therefrom to the end cars of the train where it passes around the pits of these cars in channel pieces 55 fixed on the walls of the pits, and thence is extended tortuously between the pits of the remaining cars travelling in a channel 55 on each pit. It is so arranged that it will rotate the mutually adjacent cars in opposite directions when the motor 48 is energized. The channel is shown as'without teeth, and it may be of the familiar V-channel type so that the chain will engage with sufiicient friction to turn the cars properly. It is contemplated to control the motor 48 as well as the motor of unit 3! from a central control station, and to vary the opera tion of the cars on the trucks by intermittently reversing the polarity of the current supplied through the rails, so that each car will not be always rotated in the same direction.
While I have shown and described a specific single embodiment of the invention, I do not regard the invention as limited thereto, and various changes in the construction may be made within the scope of the invention as set forth in the appended claims.
In the operation of the device as described, the cars are preferably arranged so that the interruptions or openings 55 in the C-shaped seats and backs will all be presented toward one side of the track when the train is at a predetermined loading station. Passengers may then step from the ground or from a loading platform to the plate 20, and from the latter into the pit, the legs and feet passing through the openings 56 of the seats, and backs of the cars. The ends of the backs 38 afford a ready rest or grip for the hands of the passengers as they step into the cars, and liability of misstep thus minimized. Egress of the passengers is the reverse of that for entering, and is similarly facilitated and made safe by the construction described.
All passengers being aboard, the central control operator now initiates operation of the motor unit 3| by which the chain 21 is moved through its orbit and the train drawn along the track. In traversing the curves 5'! of each end of the circuit, considerable centrifugal force is developed in the mass of the car and its load, and this mass being all above the plate 20, the plate will be flexed to a certain extent, and the car will sway toward the outer side of the track. The car construction being rigid, this sway will all be on an axis running longitudinally of the track and adjacent the plate 20. In addition, when the third rail contact is made at the points indicated, the cars will be given a sudden rotation, producing an additional element of centrifugal force, which, however, will only be manifest momentarily owing to the fact that at one part of this rotation the centrifugal force is neutralized by the force generated by translative movement of the car in a curved orbit. In consequence, the passengers are given a series of swings in a horizontal direction the intervals of said neutralization being sufficient to permit restoration of blood pressure and circulation balance or normal condition, so that no dizziness is developed among the passengers.
The sensations produced are particularly exhilarating, and at the turns of the track at the ends of the loops of the circuit, the passengers are intrigued by the appearance of an upset when the cars sway outward and the bodies of the passengers are swung in the same direction. The momentum of the car bodies and their loads will cause them to rotate for a time after the energization of the motor 48 ceases. The speed of the train on the track may approximate a rate of six to eight miles per hour to operate safely with the construction described and for the production of the desired effects. To reduce friction of rotation of the car body the lower plate 45 is formed with a concentric annular groove or channel 58 in its upper side, concentric with the pin 46, and the plate 44 is supported by rolls 59 of a diameter slightly greater than the depth of the groove 58 and engaging the lower planiforrn face of the plate 45. Additional anti-friction bearings may be provided as required in the apparatus, in accordance with approved bearing practices, for instance, as at 60 between the stud and the relatively rotating part through which it is engaged.
It should be noted that the motor 48 is mounted adjacent the inner side of the track, so that in normal use it Will be opposite the place of ingress and egress of passengers. The chain 54 passes the outer side of the sprocket 53, and runs laterally therefrom to the sides of the pits of the endmost cars, passing around the outer sides of these-that is, the sides toward the ends of the train, and thence diagonally inwardly on the train between the end cars and the next adjacent ones, passing around the inner sides of these and thence outwardly and around the pit of the central car. In this way the chain is kept well within the flanges of the channels 55, so that no guards are necessary to prevent patrons from soiling their clothes or getting garments caught under the chain.
