'- general levels.

So that all competitors shall have an equal chance, providing that equal skill is displayed, the paths to be traversed are designed, in one aspect of the game, to be of equal length or perimeter and this object is capable of attainment by various formations of tracks. The shape or configuration shown in Figure 1 is a convenient one and includes a long straight section II which serves as the starting and finishing parts of the tracks. The starting section ii may be followed by a semi-circular curve ilwhich joins a straight section 13 arranged to pass below another portion I4 of the track situated at a higher level. In this example, the tracks are arranged at two different levels connected by one incline and one decline with three bridges or crossings, but there may be several general levels, a with additional radients other than those which connect the The semi-circular curves l2 I! at the ends of the starting and finishing straight section I I are of mean equal radius, and similarly the curves l6, IT at the ends of the upper section (which includes an angle a little in excess of 180) are of equal mean radius. The remaining curves I8, l9 are likewise balanced for mean radius, and as the straight sections are respectively of common length, it will be apparent that the aggregate distance for each track is identical. The crossings are indicated at E4, 20 and 2|, the incline at 22 and the decline at 23. The construction of the tracks may include plywood platforms 24 built upon timber supports 25 as indicated in Figure 2, or moulded composition may be utilized as the basic material.

In Figure 3 I have illustrated in diagrammatic form another configuration of equi-length tracks comprising four curves 26 connected by four straight sections 2?, resulting in a petal form.

There are three general levels 26, 29 and 30 the last-mentioned being the lowest. These general level differences may occur only at the crossings, or may be extended to the petal sections. The crossings involve two descents and two in- 'clines.

- The driving force is electrical and provision is made to supply current to the vehicles by way'of feeder or conductor rails embodied in the guiding rail provided one for each machine on or in the track surface. In Figure 4, two metal conductors 3! are embedded in a hard rubber rail 22 extruded for. convenience, said conductors being of T shaped cross-section. In Figure 5 the conductor rails 3! are attached to and separated from each other by a strip of hard rubber, fibre or other insulating material 33. This construction allows connection of adjacent lengths by means of a sleeve 3% of. metal which can be soldered to ensure good electrical conductivity. A further construction shown in Figure 6 includes conductor rails of channel cross-section separated by an insulating strip and conveniently fixed down to the track platform by nails 35.

.While I have illustrated in Figures '7, 8 and 9 a miniature automobile, other vehicles may be used, the general shape of the body or-cover being suitably adapted to emulate that of, for example, an airplane, airship, motor boat, etc. while retaining the characteristics of the invention by the provision of a machine which is subject to the natural law of centrifugal force for the production of skidding and consequential loss of speed on curves or corners unless the speed at which they are negotiated is reduced by the player below'the speed of travel on the straight. The miniature automobile shown in Figures 7, 8 and 9 comprises a body 36 with rear axle I1 and driving wheels 38 coupled through gearing SI with an electric motor 40. At the front, the car is supported upon a front axle 4| and steering wheels 42, said axle being in the form of a beam pivoted loosely at 43 to the body of the car to allow the rear end to move under the influence of centrifugal force when rounding curves or corners for the purpose of diminishing speed if the curve or corner is taken at a speed exceeding a pre-determined optimum velocity. The vehicle is guided at the front bycontact with the upstanding guide rail, and hinged contact slippers 44 maybe adapted both to supply current to the machine and to cause the vehicle to follow the guide rail.

In-the diagram of electric connections shown in Figure 10, 45 is a source of electric power either battery or mains; 46 and 41 are conductor rails; 48 are the variable resistancesin circuit with the respective conductor rails and relevant vehicles; and 4 are the switches, one for each vehicle and associated circuit, by which the competitors are able to control the speed of their respective vehicles, by interrupting the relevant circuit and thereby cutting off the supply of current thereto. For convenience in bringing the machines to a standstill at the end of a race, a dead section of track may be incorporated and combined with means adapted to bring said dead section into operation at the correct time before the end of the last lap when a plurality of laps constitutes a race. Such timing may be performed manually or automatically. In the former case, a switch 49 is wired to enable a section 50 of each pair of conductor rails to be cut out by the attendant after the last vehicle has commenced the ultimate lap.

While it is preferable to employ equi-length tracks and similar machines with a view to obtaining equity of opportunity for the display of equal skill on the part of competitors, it is found that the limitations of commercial manufacture make it difficult to realize identity of speed as between one machine and another and therefore it is desirable to provide some means for balancing the combined effect of track and initial machine speed. To this end, the elapsed time per circuit or lap can be adjusted and brought into identity by adjustment of the variable resistances 48. As a corollary it follows that the invention includes a plurality of tracks which are of unequal length and/or with different curvatures, compensation for which is obtained by adjusting the maximum speed of the various vehicles by means of the resistances 48. Unlike gradients may be dealt with in a similar manner. Alternatively, the 'ohmic resistance of some of the sections of conductor rail-may be different as between one circuit and another circuit to produce an equal time-basis for each competitor.

The players having taken up their positions in front of the control switches and the vehicl:s brought to the starting line, the game is started by closing the master switch 5| Figure 10, or the switch 49 may be arranged to perform also this function. The machines thus set in motion proceed along the straight section II to enter the first curve. It will be observed that the innermost machines have to traverse the shortest path on the first bend and on the last bend whereas on the two intermediate main curves, they are on the outermost track. Conversely, the outermost machine traverses the longest path on the first and last bends, and the shortest path on the two intermediate bends. Themaximum speed when the electric power is not diminished by a said axle and the main structure of the vehicle to allow the rear of the vehicle to slew on one or competitor, is sufliciently high to produce lateral more of said curves or corners and the rear wheels skidding or side-slippingon some or all or the curves or corners by the eflect o1 centrifugal force, and therefore the speed of negotiation must be reduced by the player by cutting off the supply of current. Conveniently the control is in the form of a push-button mounted to move up and down in a surround which forms a rest for the player's hand. The element of skill resides in the players control oi. the speed at which the curves are taken, and the player who displays the most skill in taking the curves at optimum speed without skidding sufliciently to slow the vehicle, wins the race. The machines are constructed to run at high speeds so that it is necessary to cut out before reaching the curves or some of them, thereby to enhance the pleasure and entertainment of the players and onlookers.

The apparatus described herein permits 01 a reproduction on an inex nslve scale of the thrills and excitement hither associated with motor car racing on the full size scale. When the rear of the machine slews under the influence oi. centrifugal force, one of the rear wheels com s into contact with the upstanding guide rail and is thereby slowed down, or the dimensions of the machine may be such that the body is brought into contact with one of the front wheels, or otherwise slowed down. It may be that one of the rcar wheels jumps the guide rail but as the motor continues to drive, the effect is generally that the rear wheels will creep over the guide rail until in the correct position for normal running and driving. Very excessive speeds on the curves may cause a vehicle to overturn but except under these extreme conditions, the horizontal tongue 52 Figure 9 on the contact slipper 44 will hold the vehicle to the guide rail in a vertical direction upwards of the track. a

A signal, lamp, or other indicator may be combined with each track so that the competitors may have a visual indication as to which is the first car to pass the winning post. Such device is desirable to avoid disputes between players, in

view of the high speeds attained and the close.

finishes which may occur.

To check the number of races run, even when the complement is not a full one, a counting means may be used and operated by each car on each lap so that the takings may be verified. Coin-freed apparatus may be employed in combination with the apparatus described whereby the players may themselves start the game, the coin either operating through mechanical means or being utilizedas an element of the electric circuits oi the vehicles.

Apparatus as described herein incorporates two desirable features; provision for the exercise of skill; and an embodiment of the spirit of competition; allied to an equity of opportunity for the exercise of equal skill, which render the game one of particular pleasure'and interest.
