Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
194 words
In an electric dry-shaver including in a housing a motor with a reciprocally movable armature and a reciprocal cutter of a long hair clipper, the improvement in combination therewith of coupling means for driving said cutter, comprising a drive lever having a lower end pivotally engaged to said armature, an upper end pivotally engaged to said cutter, and intermediate said ends first pivot means, an actuating member mounted on said housing and movable between a first operative position and a second inoperative position, this member having a second pivot means generally adjacent said first pivot means of said drive lever, said actuating member, when moved to its first position having its second pivot means engaged to said first pivot means in a pivot connection, said drive lever with its lower end driven reciprocally by said armature, pivots about said pivot connection and has its upper end and said engaged cutter being reciprocally driven, and said actuating member when moved to its second position rendering said first and second pivot means dis-engaged and said cutter in operative, with said drive lever having its lower end reciprocally driven while its upper end becomes a pivot point.
Claim 2
Dependent Claim
194 words
In an electric dry-shaver including in a housing a motor with a reciprocally movable armature and a reciprocal cutter of a long hair clipper, the improvement in combination therewith of coupling means for driving said cutter, comprising a drive lever having a lower end pivotally engaged to said armature, an upper end pivotally engaged to said cutter, and intermediate said ends first pivot means, an actuating member mounted on said housing and movable between a first operative position and a second inoperative position, this member having a second pivot means generally adjacent said first pivot means of said drive lever, said actuating member, when moved to its first position having its second pivot means engaged to said first pivot means in a pivot connection, said drive lever with its lower end driven reciprocally by said armature, pivots about said pivot connection and has its upper end and said engaged cutter being reciprocally driven, and said actuating member when moved to its second position rendering said first and second pivot means dis-engaged and said cutter in operative, with said drive lever having its lower end reciprocally driven while its upper end becomes a pivot point.
Claim 3
Dependent Claim
30 words
Electric dry-shaver as claimed in claim 1, characterized in that the first pivot means is a pivot pin and the second pivot means is a journal for the pivot pin.
Claim 4
Dependent Claim
29 words
Apparatus according to claim 1 further comprising third pivot means between said actuating member and said housing whereby said actuating member is pivotable between its first and second position.
Claim 5
Dependent Claim
39 words
Apparatus according to claim 1 wherein said first and second pivot means when engaged include a first pivot axis of said drive lever, and Said motor armature is pivotable about a second pivot axis, said two axes being parallel.
Claim 6
Dependent Claim
15 words
Apparatus according to claim 4 wherein said first axis substantially coincides with said second axis.
Claim 7
Dependent Claim
63 words
Apparatus according to claim 1 wherein said first pivot means comprises a first projection having first diameter, and said second pivot means comprises a pair of second projections spaced apart a distance slightly greater than said first projection diameter, said first and second pivot means being engaged when said first projection is situated between said two second projection of said second pivot means.
Claim 8
Dependent Claim
28 words
Apparatus according to claim 1 wherein said actuating member is a knob rotatable mounted to said housing, said knob being rotatable between said first and second position thereof.
Claim 9
Dependent Claim
42 words
Apparatus according to claim 3, wherein said third pivot means includes a pivot axis approximately midway between the ends of said actuating member, the shaver further comprising a bistable spring means biasing said actuating member to either of two stable pivotal positions.
