  • Patent number: 6158737
    Abstract: A pinball machine has been designed with several novel mechanical and electrical features such that it is easily retrofittable or convertible between a first pinball game and a second pinball game. One of these features is a novel playfield assembly for the pinball machine. For ease of movement of the playfield into and from a cabinet of the pinball machine, the playfield has skid rails which extend substantially along the length of the playfield. The skid rails are spaced from the lower side of the playfield by a distance that is greater than the distance by which components protrude from the lower side of the playfield. Thus, the playfield can be placed on the ground without any chance for damage of its components. The playfield may also include a slide stop at one or both of its ends. The slide stops engage the front molding of the cabinet to ensure the playfield does not fall into the cabinet or fall from the cabinet as the skid rails are being slid across the front molding.

  • Patent number: 5356141
    Abstract: The play feature for a pinball game of the present invention comprises a roulette scoring device mounted above the playfield which includes a horizontally rotating wheel having a plurality of apertures arrayed around its periphery. A different point value indicated to the player is associated with each of the apertures. Pinballs can enter the roulette scoring device not only from the shooter lane, but also from a ramp disposed on the playfield. An optical switch or microswitch included in the ramp adjacent a holding device and a microswitch in the shooter lane generate signals sent to the game microprocessor to cause the wheel to rotate. An optical switch mounted on the playfield senses the return of the ball to the playfield and signals the game microprocessor to stop the rotation of the wheel and to add the appropriate point value to the player's score.

  • Patent number: 5342049
    Abstract: A gaming machine combines a random selection feature with a skill feature to allow the player to utilize his ability to manipulate the skill feature to improve his chances of winning on the gaming machine. A reel slot machine is combined with a playing surface using a ball. The reel slot machine is first activated and a combination of slot symbols are randomly selected. The player manipulates a ball about a playing surface and the travel of the ball can result in additional spins of one or more reels of the slot machine so that other winning opportunities can be created. The gaming machine can be operated so that the playing surface is only activated when the player achieves a losing combination on the reel slot machine portion. This allows the player a second chance to win if he can use his skill on the playing surface to respin the reel slots. The player can also win "bonus" amounts as set out on a predetermined schedule of payouts by his skillful manipulation of the ball on the playing surface.

  • Patent number: 5338031
    Abstract: The tilt switch/incline indicator of the invention consists of a first support member that is connected to the game cabinet in a known orientation. A second member is pivotably supported on the first member and can be fixed relative thereto at angles corresponding to the desired angle of incline of the playfield. The second member supports a pendulum-type tilt switch similar to that used in the prior art. The pendulum acts like a plumb line to give a visual indication to the game operator that the playfield is at the desired angle set at the second member by observing when the pendulum is centered relative to the contact. The mechanism of the invention uses the tilt switch as the level indicator such that the playfield can be positioned at a known angle without requiring a separate level indicator or the recalibration to the tilt switch.

  • Patent number: 5335910
    Abstract: A pinball elevator has an inclined conveyor belt tensioned between two pulleys and driven by an electric motor. The belt is perforated with a series of spaced circular apertures for receiving the pinball. Preferably, the apertures have a diameter of about 80% of the diameter of the pinball. A lower one of the pulleys is rotatably mounted beneath the playfield of the pinball machine, and an upper one of the pulleys is rotatably mounted above the playfield. The ball is received by the belt at an entrance location, and is ejected from the belt at an exit location. The ball passes above and over the upper pulley when being conveyed by the belt from the entrance location to the exit location. The upper pulley has a concave central region to prevent the pinball from being prematurely ejected from the belt by the upper pulley. At the entrance location, the pinball sits on the belt and abuts against a wall of the playfield.

  • Patent number: 5333866
    Abstract: A pinball machine has a plurality of ball-deflecting components mounted to a playfield section. The playfield section is selectively translated in response to player input, so that the ball is deflected by the ball-deflecting components to locations selected by the player. The translation of the playfield section, for example, is responsive to the conventional push-button switches that are operated by the player for activating flippers, and in this case the push-buttons activate respective solenoids for translating the playfield section in two different directions. The playfield section, however, could be translated in different directions along two or three orthogonal axes in response to a more complex player-input device such as a joy-stick.

  • Patent number: 5226653
    Abstract: The play feature of the invention consists of a three level target assembly where the uppermost level is mounted on a section of the playfield. The two lower levels are mounted to the underside of the playfield section such that upon activation of the play feature's drive system, the playfield section is raised to sequentially expose the two lower levels. In the preferred embodiment, the upper level includes ball ejector holes, the middle level includes button targets and the lower level includes ball diverting chutes. The game's microprocessor can be programmed to allow the ball ejector holes to eject the trapped ball only after the player completes a predetermined series of shots using a second ball. In such a situation, the ejection of the trapped ball will result in multi-ball play where more than one ball is in play at the same time.

  • Patent number: 5158291
    Abstract: A ball accelerator mechanism employs one or more electromagnetic coils in combination with sensor elements to accelerate a rolling ball made of ferro-magnetic material. As a ball approaches the coil, it operates the sensor applying a DC current pulse to the coil. As the ball enters the coil, it is magnetically accelerated until it clears the sensor at which time the current is turned off. The length of the current pulse is thus a function of ball velocity. Preferably to maximize acceleration, the width of the coil is an integral multiple of the ball diameter.
