Abstract
Abstract An amusement device comprising a plurality of rotatable wheels that can be rotated independently of one another either clockwise or counterclockwise. Each wheel is divided into sectors and each sector bears different indicia. Braking mechanism is provided and constructed so that all of the sectors of one wheel are aligned with all of the sectors of another wheel or with all of the sectors of the other wheels at the time the wheels have ceased moving. The braking mechanism is in the form of first brake shoes attached to the respective wheels and second fixed brake shoes which are radially aligned with respective first brake shoes when the indicia sectors are aligned. The first and second brake shoes have cooperating contoured surfaces, are resiliently radially biased into engagement with each other, and are provided magnets to aid in the alignment of the indicia sectors.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
166 words
An amusement device comprising in combination: a support, a shaft fixed to said support, a plurality of radially disposed wheels rotatable carried by said shaft, and said wheels being rotatable independently of one another and having radially disposed display faces, said display faces being divided into a plurality of sections carrying distinctive indicia, braking means for each wheel for braking said wheels to a stop and aligning the then adjacent sections of said wheels into radial alignment, said brake means comprising first brake shoes circumferentially fixed with respect to each of said wheels and having contoured surfaces, a plurality of second brake shoes fixed to said support, one of said second brake shoes being in radial alignment with each of said first brake shoes when the indicia carrying sections are radially aligned, said second brake shoes having surfaces contoured for generally complementary engagement with said first brake shoes, said first and second brake shoes being supported for guided biased radial movement into engagement with each other.
Claim 2
Dependent Claim
166 words
An amusement device comprising in combination: a support, a shaft fixed to said support, a plurality of radially disposed wheels rotatable carried by said shaft, and said wheels being rotatable independently of one another and having radially disposed display faces, said display faces being divided into a plurality of sections carrying distinctive indicia, braking means for each wheel for braking said wheels to a stop and aligning the then adjacent sections of said wheels into radial alignment, said brake means comprising first brake shoes circumferentially fixed with respect to each of said wheels and having contoured surfaces, a plurality of second brake shoes fixed to said support, one of said second brake shoes being in radial alignment with each of said first brake shoes when the indicia carrying sections are radially aligned, said second brake shoes having surfaces contoured for generally complementary engagement with said first brake shoes, said first and second brake shoes being supported for guided biased radial movement into engagement with each other.
Claim 3
Dependent Claim
21 words
An amusement device as defined in claim 1 wherein: said first and second brake shoes are resiliently biased toward one another.
Claim 4
Dependent Claim
26 words
An amusement device as defined in claim 2 wherein: said brake shoes are guided toward one another by pins received in holes in a guide support.
Claim 5
Dependent Claim
43 words
An amusement device as defined in claim 3 wherein: said holes in said guide support have sufficient clearance to permit a rocking rotation of said guide shoes, said rocking rotation being about an axis which is parallel to the axis of said shaft.
Claim 6
Dependent Claim
23 words
An amusement device as in claim 2 wherein: the complementary contoured surfaces of said brake shoes comprise a concave and a convex surface.
Claim 7
Dependent Claim
28 words
An amusement device as defined in claim 5 further including: magnets imbedded in the surface of said shoes in substantially the center thereof and with opposite poles facing.
