     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The amusement device of the present invention, as illustrated in FIG. 1, consists of a continuous trackway designated by the reference numeral 10 comprised of a plurality of sections 12 and a control section 14 which are joined together, and a plurality of powered vehicles 16 and 18. As illustrated in FIG. 3, the ends of adjacent of the sections 12 and 14 are provided with locking flanges 16 and 19 permitting the sections 12 and 14 to be assembled by pressing the depending cylindrical members 20 within the openings 22. 
     Each of the sections 12 of the trackway is provided with upstanding rails 24 and 26, and channels 28 and 30 within which the guiding flanges 32 of the vehicles 16 and 18 are positioned so as to guide the vehicles 16 and 18 along the trackway 10. 
     It will be apparent from FIG. 2 that the control section 14 is provided at the lefthand side thereof with a rail 34 and guide channels 28&#39; and 30&#39; on each side thereof which are contiguous with the channels 28 and 30 of the adjacent section 12, and in similar manner on the righthand side thereof with a rail 36, and guide channels 28&#39; and 30&#39; on each side thereof which are contiguous with the guide channels 28 and 30. A movable rail 38 is mounted to the end of the rail 36 with a pin 40 for movement within the cavity 42 to direct the vehicles 16 and 18, as described hereinafter. 
     As illustrated in FIG. 9, each of the vehicles 16 and 18 is provided with a conventional miniature electric motor 44 powered by a source of electrical energy. When the motor 44 is energized the spur gear 46 at the end of the shaft 48 meshes with and drives the crown gear 50 causing the shaft 52 journalled within the chassis of the vehicle to rotate. Fixed to the shaft 52 is a gear wheel 54 which meshes with the gear 56 mounted on the shaft 58 which is also journalled within the chassis. The gear 60 of the shaft 58 meshes with the gear 62 which is secured to the axle 64 to which the wheels 66 and 68 are attached. With reference to FIGS. 4-5, it will be apparent that when guiding flange 32 of the vehicles 16 and 18 is within the channel 30, the tread 70 along the periphery of the wheel 68 meshes with and advances along a similar tread formed on the surface 72 of each of the sections 12 while the rim 74 of the wheel 66 engages the top surface of the sections 12. When the guiding flange 32 is within the channel 28, the tread 74 formed along another portion of the wheel 68 that is smaller in diameter and circumference than the tread 70, engages the top of the rail 26 while the wheel 66 engages the top of the rail 24. Since the axle 64 rotates at constant speed, and the diameter of the tread 70 is greater than that of the tread 74, it will be apparent that the vehicles 16 and 18 move faster when the flanges 32 are within the guide channels 30 (FIG. 4) than when the flanges 32 are within the guide channel 28 (FIG. 5). 
     The mechanism for operating the movable rail 38 is illustrated in FIGS. 2, 6 and 7. As will be described hereinafter, the movable rail 38 is normally held in the position illustrated in solid lines in FIG. 2 so as to direct the vehicles into the guide channel 28&#39; to propel the vehicles at their slower speed. By depressing the buttons 76, which extend upwardly through section 14, the rail 38 is rotated upwardly about pin 40 to the position shown in dotted lines in FIG. 2, such that the guiding flanges 32 of the vehicles will be directed into the channel 30&#39;. As seen in FIG. 7, the movable rail 38 is provided with a post 78 which is positioned within a slot 80 within the plate 82 which is provided with a post 84 mounted for rotation to the section 14. The spring 86, which is secured at one end to the plate 82 and at the other end to the casing of the section 14, normally urges the plate 82 to rotate about an axis corresponding to the post 84 such that the slot 80 adjusts the position of the post 78 and the movable rail 38, as illustrated in solid lines in FIG. 2. Extending outwardly from the plate 82 are a pair of arms 88. Located immediately below the buttons 76 are levers 90 having posts 92 which are journalled for rotation to the casing of the section 14, such that as the buttons 76 are depressed the bottoms thereof engage the ends 94 of the levers 90 causing the other ends 96 of the levers 90 to move upwardly eventually engaging the arms 88 of the plate 82 causing the plate 82 to rotate against the force of the spring 86 causing the slot 80 of the plate 82 to change the position of the post 78 moving the rail 38 to the position illustrated in dotted lines in FIG. 2. From the foregoing, it will be apparent that each of the players may depress his button 76 when the vehicles 16 and 18 enter the control section 14 for the purpose of positioning the movable rail 38 to guide the flanges 32 of the vehicles into the guide channel 30&#39; to achieve the greater of the two possible speeds along the trackway 10. 
     The control section 14 is also provided with a button 98 which moves abutments 100 and 102, illustrated in FIG. 2, in and out of guide channels 28&#39; and 30&#39;, respectively. From FIGS. 2 and 6, it will be apparent that button 98 extends upwardly from a plate 104 which is slidably mounted within the casing of section 14. The plate 104 is provided with an opening 106 through which a post 108, which extends upwardly from a lever 110, passes. The lever 110 is provided with an opening 112 through which a post 114 formed as a part of the chassis extends, thus permitting the lever 110 to rotate about the post 114 as the button 98 is moved. The abutments 100 and 102 are formed as an integral part of the lever 110 and as seen in FIG. 6 extend upwardly from the ends therefrom. From the foregoing, it will be apparent that when the button 98 is moved forwardly to the position illustrated in FIG. 2, the abutments 100 and 102 are moved into blocking position within the guiding channels 28&#39; and 30&#39;, respectively, thus preventing movement of the vehicles 16 and 18 through the section 14. In this manner, it is possible to activate the motors of the vehicles 16 and 18 and to position the vehicles in their &#34;starting&#34; positions at abutments 100 and 102, and thereafter move the button 98 rearwardly removing the abutments 100 and 102 from the channels 28&#39; and 30&#39; into the cavities 116 and 118 permitting the vehicles 16 and 18 to move forward. 
     From FIG. 8, it will be apparent that the flanges 32 of the vehicles 16 and 18 are attached to a plate 120 which is mounted to rotate about a shaft 122 journalled within the walls of the chassis 124. A spring 126 is coiled around the shaft 122 and has one end thereof resting against the plate 120 and the other end resting against the chassis 124, thus normally urging the plate 120 to rotate in a counterclockwise direction. The chassis 124, as seen in FIG. 9, is provided with a rigid plate 128 having a post 130 about which one end of a coil spring 132 is positioned. The plate 128 includes shoulders 131 which accommodate the flanges 133 of the housing 134, thus permitting the housing 134 to slide relative to the plate 128. The rod 136 is provided at one end with a housing 138 into which the other end of the spring 132 is positioned, and it will be apparent that the housing 138 fits within a cavity 140 (FIG. 10) within the housing 134. The assembled components are illustrated in FIGS. 10-12 wherein it will be apparent that the spring 132 normally urges the housings 134 and 138 and the rod 136 outwardly. The housing 134 is also provided with a recessed surface 142 accommodating the latching member 144 of the plate 120, permitting the plate 120 to be rotated against the force of the spring 126 until the latching member 144 is secured by the recessed surface 142 of the housing 144. When the rod 136 is moved inwardly against the force of the spring 132, the housing 134 is moved inwardly causing the latching member 144 to be released, thus permitting the plate 120 to rotate to its open position, as illustrated in FIG. 8. 
     Operation of the rod 136 to release the plate 120 is illustrated in FIGS. 10-12, but initially attention is directed to FIG. 9 wherein it will be apparent that the axle 64 to which the gear 62 is attached is provided with a cam element 146, while the rod 136 is provided with an upstanding abutment 148 which normally is positioned to the right of the cam element 146. As the rod 136 is moved to the left, as illustrated in FIG. 11, the abutment 148 is eventually positioned to be engaged by the rotating cam element 146. The cam element 146 thus abruptly strikes the abutment 148 forcefully urging the rod 136 further to the left against the force of the spring 132, as illustrated in FIG. 12, thus freeing the latching element 144 from the recessed surface 142 of the housing 134 causing the plate 120 to abruptly rotate to the open position under the influence of the spring 126. It will be apparent that when the plate 120 abruptly rotates to its open position, the vehicles 16 and 18 are caused to somersault forwardly leaving the trackway 10 signalling that the game is over. 
     As illustrated in FIGS. 8 and 13, the front of each of the vehicles 16 and 18 is provided with two striking members 150. From FIG. 13, it will be apparent that when the flange 32 of the vehicle 16 is within the guiding channel 30, and the flange 32 of the other vehicle 18 is within the guiding channel 28, and the vehicle 16 is thus moving more rapidly than the vehicle 18, one of the striking members 150 is aligned with the rear end of the reciprocally mounted rod 136, such that as the vehicle 16 overtakes the vehicle 18 the striking member 150 engages the end of the rod 136 moving same inwardly, until the rotating cam element 146 strikes the abutment 148 abruptly urging the rod 136 still further forward permitting the plate 120 to open causing the vehicle 18 to somersault off of the trackway 10 signalling that the vehicle 16 is the &#34;winner&#34;. It will also be apparent from FIG. 13 that when the flanges 32 of both of the vehicles 16 and 18 are travelling along the same guiding channel, either channel 28 or 30, the striking members 150 are offset from the end of the rod 136, thus preventing the striking members 150 from engaging the rod 136 and activating the rotating plate 120. Thus, the catipulting of a vehicle from the trackway 10 can only occur when one of the vehicles is travelling along the outside, faster path and the other vehicle is travelling along the inside, slower path. 
     The game is initiated by the players positioning their respective vehicles 16 and 18 behind the abutments 100 and 102. The motors of the vehicles 16 and 18 are started, and the button 98 is moved rearwardly removing the abutments 100 and 102. The movable rail 38 normally diverts the vehicles from the faster guiding channel 30&#39; to the slower guiding channel 28&#39;, while directing vehicles that are already in the slower guiding channel 28&#39; to continue along the slower guiding channel 28&#39;. As the vehicles approach the control section 14, the players depress the buttons 76 moving the rail 38 forwardly for the purpose of attempting to gain access to the faster guiding channel 30&#39;. The race continues until one of the vehicles is in the faster guiding channel 30 and the other vehicle is in the slower channel 28, and the faster of the vehicles overtakes the slower of the vehicles, at which time the appropriate striking member 150 engages the rod 136 causing the slower of the vehicles to be catapulted off of the trackway signalling the end of the game. Derailment does not occur when both vehicles are moving either along the slower channels of the faster channels.
