Abstract
Abstract A dry-shaving apparatus is provided with hair-trimming means comprising two pairs of cooperating toothed cutters, each pair of cutters consisting of a reciprocatory cutter and a stationary cutter. One pair of cutters is adjustable between different positions and forms a first hair trimmer of relatively short length for trimming hairs which are not easy to get at with a full-length hair trimmer, for example, hairs in the ears. The other pair of cutters either is arranged for operation in line and in juxtaposition with the first pair of cutters in one of the positions thereof so as to form with the first pair of cutters a second hair trimmer of greater length than the first hair trimmer, or has a greater length than the first pair of cutters and forms a full-length second hair trimmer independently of the first hair trimmer.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
174 words
A dry-shaving apparatus provided with hair-trimming means comprising a first pair of cooperating toothed cutters, one being reciprocatory and the other being stationary in operation, said first pair of cutters forming a first hair trimmer and being adjustable between different positions; and a second pair of cooperating toothed cutters, one being reciprocatory and the other being stationary in operation, said second pair of cutters being arranged for operation in line and in juxtaposition with the first pair of cutters in at least one of said positions thereof so as to form with the first pair of cutters a second hair trimmer of greater length than the first hair trimmer measured in the direction of reciprocation of the reciprocatory cutters, or said second pair of cutters having a greater length than the first pair of cutters measured in the direction of reciprocation of the reciprocatory cutter of each pair of cutters and being arranged to form independently of the first pair of cutters a second hair trimmer of greater length than the first hair trimmer.
Claim 2
Dependent Claim
174 words
A dry-shaving apparatus provided with hair-trimming means comprising a first pair of cooperating toothed cutters, one being reciprocatory and the other being stationary in operation, said first pair of cutters forming a first hair trimmer and being adjustable between different positions; and a second pair of cooperating toothed cutters, one being reciprocatory and the other being stationary in operation, said second pair of cutters being arranged for operation in line and in juxtaposition with the first pair of cutters in at least one of said positions thereof so as to form with the first pair of cutters a second hair trimmer of greater length than the first hair trimmer measured in the direction of reciprocation of the reciprocatory cutters, or said second pair of cutters having a greater length than the first pair of cutters measured in the direction of reciprocation of the reciprocatory cutter of each pair of cutters and being arranged to form independently of the first pair of cutters a second hair trimmer of greater length than the first hair trimmer.
Claim 3
Dependent Claim
136 words
A dry-shaving apparatus including a housing and provided with hair-trimming means comprising a first pair of cooperating toothed cutters, one being reciprocatory and the other being stationary in operation, said first pair of cutters forming a first hair trimmer and being adjustable between different positions; and a second pair of cooperating toothed cutters, one being reciprocatory and the other being stationary in operation, said second pair of cutters being arranged for operation in line and in juxtaposition with the first pair of cutters in at least one of said positions thereof so as to form with the first pair of cutters a second hair trimmer of greater length than the first hair trimmer measured in the direction of reciprocation of the reciprocatory cutters; the two pairs of cutters being mounted on one wall of said housing.
Claim 4
Dependent Claim
136 words
A dry-shaving apparatus including a housing and provided with hair-trimming means comprising a first pair of cooperating toothed cutters, one being reciprocatory and the other being stationary in operation, said first pair of cutters forming a first hair trimmer and being adjustable between different positions; and a second pair of cooperating toothed cutters, one being reciprocatory and the other being stationary in operation, said second pair of cutters being arranged for operation in line and in juxtaposition with the first pair of cutters in at least one of said positions thereof so as to form with the first pair of cutters a second hair trimmer of greater length than the first hair trimmer measured in the direction of reciprocation of the reciprocatory cutters; the two pairs of cutters being mounted on one wall of said housing.
Claim 5
Dependent Claim
27 words
A dry-shaving apparatus according to claim 2, in which the two pairs of cutters having equal lengths measured in the direction of reciprocation of the reciprocatory cutters.
Claim 6
Dependent Claim
30 words
A dry-shaving apparatus according to claim 2, in which the second pair of cutters also is adjustable between different positions corresponding to said positions of the first pair of cutters.
Claim 7
Dependent Claim
164 words
A dry-shaving apparatus including a housing of substantially rectangular cross-section with two oppositely disposed wide side walls and two oppositely disposed narrow side walls and provided with hair-trimming means comprising a first pair of cooperating toothed cutters, one being reciprocatory and the other being stationary in operation, said first pair of cutters forming a first hair trimmer and being adjustable between different positions; and a second pair of cooperating toothed cutters, one being reciprocatory and the other being stationary in operation, said second pair of cutters having a greater length than the first pair of cutters measured in the direction of reciprocation of the reciprocatory cutter of each pair of cutters and being arranged to form independently of the first pair of cutters a second hair trimmer of greater length than the first hair trimmer; the first pair of cutters being mounted on one of the narrow side walls and the second pair of cutters being mounted on one of the wide side walls.
Claim 8
