Abstract
Abstract A play feature for a pinball game having a plurality of wheels rotatable about a horizontal axis and having a plurality of ball receiving sockets formed therein. Each wheel can pick up a pinball from a first position on the playfield and after rotating through approximately 180 degrees discharge the pinball at a second position on the playfield. The wheels are arranged in a series whereby the discharge position of the upstream wheel corresponds to the pick up position of the downstream wheel. In this manner the pinball can be conveyed across the playfield in a stepped fashion as it is transferred from the upstream wheel to the downstream wheel. The rotation of the wheels is coordinated by using a single drive motor operatively connected to each of the wheels by a transmission member. Finally, downfield wheels can be arranged at different elevations relative to the playfield such that the pinball can be raised or lowered relative to the playfield by the successive wheels as the pinball is conveyed across the playfield.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
A pinball game comprising: (a) an inclined playfield for supporting a rolling ball and a plurality of play features; (b) one of said plurality of play features comprising: (1) a first ball engaging means movably supported adjacent to the playfield for picking up the rolling ball at a first location on the playfield and discharging the ball at a second location; (2) a second ball engaging means movably supported relative to the playfield for picking up the ball at the second location and discharging it at a third location remote from the first location; (3) means for sensing the presence of the ball in the first position and for generating a signal in response thereto; (4) means for moving the first and second ball engaging means relative to the playfield in response to said signal; and (5) means for coordinating the rotation of said first and second ball engaging means to provide synchronous operation therebetween; whereby the ball is moved over the playfield by the first and second ball engaging means.
Claim 2
Dependent Claim
171 words
A pinball game comprising: (a) an inclined playfield for supporting a rolling ball and a plurality of play features; (b) one of said plurality of play features comprising: (1) a first ball engaging means movably supported adjacent to the playfield for picking up the rolling ball at a first location on the playfield and discharging the ball at a second location; (2) a second ball engaging means movably supported relative to the playfield for picking up the ball at the second location and discharging it at a third location remote from the first location; (3) means for sensing the presence of the ball in the first position and for generating a signal in response thereto; (4) means for moving the first and second ball engaging means relative to the playfield in response to said signal; and (5) means for coordinating the rotation of said first and second ball engaging means to provide synchronous operation therebetween; whereby the ball is moved over the playfield by the first and second ball engaging means.
Claim 3
Dependent Claim
33 words
The playfield feature according to claim 1, wherein said first and second ball engaging means comprise wheels supported for rotary movement about a horizontal axis and having at least one ball receiving means.
Claim 4
Dependent Claim
27 words
The playfield feature according to claim 2, wherein said wheels each include four ball receiving means located at 90 degree intervals about the periphery of the wheels.
Claim 5
Dependent Claim
25 words
The playfield feature according to claim 2, wherein said wheels include a transparent portion whereby the pinball is visible while in the ball receiving means.
Claim 6
Dependent Claim
29 words
The playfield feature according to claim 1, wherein said means for coordinating includes a transmission member for transmitting the rotary motion to said first and second ball engaging means.
Claim 7
Dependent Claim
35 words
The playfield feature according to claim 5, wherein said transmission member comprises a drive belt engageable with pulleys connected to said first ball engaging means, said second ball engaging means, and said means for rotating.
Claim 8
Dependent Claim
36 words
The playfield feature according to claim 6, further including an adjustably mounted pulley engageable with said drive belt whereby a change in the position of the adjustably mounted pulley changes the tension on the drive belt.
Claim 9
Dependent Claim
41 words
The playfield feature according to claim 1, further including an inclined ramp defining said second location whereby when said ball is discharged from the first ball engaging means it rolls under the force of gravity to said second ball engaging means.
Claim 10
Dependent Claim
20 words
The playfield feature according to claim 1, further including a frame for supporting said first and second ball engaging means.
Claim 11
Dependent Claim
20 words
The playfield feature according to claim 1, wherein said first and second ball engaging means are located at different elevations.
