Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 115 words
Typewriter shield apparatus comprising: A. support means adapted for cooperation with a typewriter keyboard and copy being typed; and B. a typewriter shield assembly mounted on said support means comprising a screen member incorporating at least two pivotally interconnected sections readily movable between a. a complete typewriter view obstructing position wherein said screen member sections lie in substantially the same plane shielding from view said keyboard and said copy being typed, and b. a partial typewriter view obstructing position wherein at least one of said screen member sections overlies another screen member section shielding from view either said keyboard or said copy, and c. a position allowing both the keyboard and copy to be viewed.
Claim 2
Dependent Claim 115 words
Typewriter shield apparatus comprising: A. support means adapted for cooperation with a typewriter keyboard and copy being typed; and B. a typewriter shield assembly mounted on said support means comprising a screen member incorporating at least two pivotally interconnected sections readily movable between a. a complete typewriter view obstructing position wherein said screen member sections lie in substantially the same plane shielding from view said keyboard and said copy being typed, and b. a partial typewriter view obstructing position wherein at least one of said screen member sections overlies another screen member section shielding from view either said keyboard or said copy, and c. a position allowing both the keyboard and copy to be viewed.
Claim 3
Dependent Claim 34 words
Apparatus as defined in claim 1, wherein said typewriter shield assembly further comprises: c. a holding bar, adjustably mounted to said support means, and d. said screen member pivotally mounted to said holding bar.
