Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
84 words
An amusement device comprising upper and lower plates and a side wall forming a closed container having a hollow space with a fluid therein, a bubble of material different from said fluid which moves therein, means forming a channel surrounding said hollow space of said closed container, said channel forming means including said side wall, and a passageway through said side wall for selectively admitting a part of the bubble from the hollow space into the channel for controlling the size of the bubble.
Claim 2
Dependent Claim
84 words
An amusement device comprising upper and lower plates and a side wall forming a closed container having a hollow space with a fluid therein, a bubble of material different from said fluid which moves therein, means forming a channel surrounding said hollow space of said closed container, said channel forming means including said side wall, and a passageway through said side wall for selectively admitting a part of the bubble from the hollow space into the channel for controlling the size of the bubble.
Claim 3
Dependent Claim
74 words
The device of claim 1 further comprising a separator plate in said hollow space between said upper and lower plates dividing said hollow space into upper and lower compartments, at least one opening in said separator plate providing communication for said bubble between the upper and lower compartments and a slot through said separator plate of larger area than a said opening providing further communication for said bubble between the upper and lower compartments.
Claim 4
Dependent Claim
31 words
The device of claim 2 wherein a said opening in the separator plate tapers inwardly from a wider to a narrower cross-section from the surface toward the center of the plate.
Claim 5
Dependent Claim
20 words
The device of claim 2 wherein said slot extends through said plate lying at an angle of less than 90°.
Claim 6
Dependent Claim
35 words
The device of claim 4 further comprising means partially surrounding the opening to the slot on the upper surface of the separator plate to provide an assembly area for the bubble in the upper compartment.
Claim 7
Dependent Claim
28 words
The device of claim 5 wherein there is a restricted opening in the means surrounding the opening to the slot on the upper surface of the separator plate.
Claim 8
Dependent Claim
106 words
An amusement device comprising upper and lower plates and a side wall defining a closed container having a hollow space with a fluid therein, a bubble of a material different from said fluid which moves therein, a separator plate in said hollow space across substantially its entire area dividing it into upper and lower compartments in which the bubble can move, at least one opening in said separator plate providing communication for said bubble between the upper and lower compartments and a slot through said separator plate of larger area than a said opening providing further communication for said bubble between the upper and lower compartments.
Claim 9
Dependent Claim
106 words
An amusement device comprising upper and lower plates and a side wall defining a closed container having a hollow space with a fluid therein, a bubble of a material different from said fluid which moves therein, a separator plate in said hollow space across substantially its entire area dividing it into upper and lower compartments in which the bubble can move, at least one opening in said separator plate providing communication for said bubble between the upper and lower compartments and a slot through said separator plate of larger area than a said opening providing further communication for said bubble between the upper and lower compartments.
Claim 10
Dependent Claim
31 words
The device of claim 7 wherein a said opening in the separator plate tapers inwardly from a wider to a narrower cross-section from the surface toward the center of the plate.
Claim 11
Dependent Claim
19 words
The device of claim 7 wherein said slot extends through said plate lying at an angle less than 90°.
Claim 12
Dependent Claim
35 words
The device of claim 9 further comprising means partially surrounding the opening to the slot on the upper surface of the separator plate to provide an assembly area for the bubble in the upper compartment.
Claim 13
Dependent Claim
43 words
The device of claim 10 wherein there is a restricted opening in the means surrounding the opening to the slot on the upper surface of the separator plate to provide communication between the hollow space of the upper compartment and the assembly area.
Claim 14
Dependent Claim
94 words
An amusement device comprising upper and lower plates and a side wall defining a closed container having a hollow space with a fluid therein, a bubble of a material different from said fluid which moves therein, a separator plate in said hollow space dividing it into upper and lower compartments, at least one opening in said separator plate providing communication for said bubble between the upper and lower compartments, a said opening of said separator plate tapering inwardly from a wider to a narrower cross-section from each surface of the plate toward its center.
Claim 15
Dependent Claim
94 words
An amusement device comprising upper and lower plates and a side wall defining a closed container having a hollow space with a fluid therein, a bubble of a material different from said fluid which moves therein, a separator plate in said hollow space dividing it into upper and lower compartments, at least one opening in said separator plate providing communication for said bubble between the upper and lower compartments, a said opening of said separator plate tapering inwardly from a wider to a narrower cross-section from each surface of the plate toward its center.
