Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 290 words
An improved, electric dry shaver, comprising: (a) a hand held housing; (b) a cutter head mounted to said housing; (c) said cutter head including a demountable hair pocket having a side wall thereof, said side wall having an exterior surface thereof; (d) said cutter head having an elongated, longitudinally extending hair cutter assembly including a first stationary, apertured cutter member, and, a second reciprocating cutter member positioned in shearing engagement with said first member; (e) said cutter head assembly adapted to shear body hair which extends through said first cutter member apertures when said cutter head is positioned by a user for engaging body hair; (f) an electrically energized actuating means mounted in said housing and mechanically coupled to said reciprocating cutter member for imparting reciprocating motion to said second cutter member upon electrical energization of said actuating means; (g) an elongated, longitudinally extending skin stretcher means laterally spaced from and extending generally parallel with hair cutter assembly; (h) said skin stretcher means including a slide body mounted to said hair pocket side wall in sliding engagement with said exterior surface; and, (i) means for selectively positioning said skin stretcher slide body at a first extended position in engagement with said exterior wall surface at which said slide body engages a user's skin and causes tensioning of the skin over an area which includes the location at which said cutter head assembly engages body hair, and, for positioning said skin stretcher slide body at a second retracted position in engagement with said exterior wall surface at which position said slide body is positioned substantially out of engagement with the user's skin and does not cause tensioning thereof in the area at which said cutter head assembly engages the user's body.
Claim 2
Dependent Claim 290 words
An improved, electric dry shaver, comprising: (a) a hand held housing; (b) a cutter head mounted to said housing; (c) said cutter head including a demountable hair pocket having a side wall thereof, said side wall having an exterior surface thereof; (d) said cutter head having an elongated, longitudinally extending hair cutter assembly including a first stationary, apertured cutter member, and, a second reciprocating cutter member positioned in shearing engagement with said first member; (e) said cutter head assembly adapted to shear body hair which extends through said first cutter member apertures when said cutter head is positioned by a user for engaging body hair; (f) an electrically energized actuating means mounted in said housing and mechanically coupled to said reciprocating cutter member for imparting reciprocating motion to said second cutter member upon electrical energization of said actuating means; (g) an elongated, longitudinally extending skin stretcher means laterally spaced from and extending generally parallel with hair cutter assembly; (h) said skin stretcher means including a slide body mounted to said hair pocket side wall in sliding engagement with said exterior surface; and, (i) means for selectively positioning said skin stretcher slide body at a first extended position in engagement with said exterior wall surface at which said slide body engages a user's skin and causes tensioning of the skin over an area which includes the location at which said cutter head assembly engages body hair, and, for positioning said skin stretcher slide body at a second retracted position in engagement with said exterior wall surface at which position said slide body is positioned substantially out of engagement with the user's skin and does not cause tensioning thereof in the area at which said cutter head assembly engages the user's body.
