Abstract
Abstract A reaper razor includes a blade having a sharpened edge and a reaper member rotatably drive adjacent the blade. The reaper member pushes hair to be cut against the sharpened edge severing the hair from its shank. The blade is mounted for adjustable movement toward and away from the reaper member to accommodate reaper wear. The reaper member is made of a rubber like material having a Shore durometer hardness of 55-70, a coefficient of kenetic friction of at least 0.8 and preferably above 1.0 and is electrostatically active.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
92 words
A razor comprising a housing having an electric motor therein; a blade having a straight sharpened edge; a reaper member having a body and plurality of blades projecting therefrom; means mounting the reaper member for rotation about an axis parallel to the blade edge, the axis being spaced from the blade a distance substantially equal to the length of the reaper blades as measured from the axis; means drivably rotating the reaper member about the axis; and means mounting the blade for adjustable movement toward and away from the axis of rotation.
Claim 2
Dependent Claim
92 words
A razor comprising a housing having an electric motor therein; a blade having a straight sharpened edge; a reaper member having a body and plurality of blades projecting therefrom; means mounting the reaper member for rotation about an axis parallel to the blade edge, the axis being spaced from the blade a distance substantially equal to the length of the reaper blades as measured from the axis; means drivably rotating the reaper member about the axis; and means mounting the blade for adjustable movement toward and away from the axis of rotation.
Claim 3
Dependent Claim
15 words
The razor of claim 1 wherein the reaper blades project radially from the reaper body.
Claim 4
Dependent Claim
52 words
The razor of claim 1 wherein the blade mounting means comprises a pair of elongate converging metal strips providing a first elongate slot therebetween through which the sharpened blade edge projects, the strips providing first and second end slots for passing the blade into, through and out of the blade mounting means.
Claim 5
Dependent Claim
51 words
The razor of claim 3 wherein the blade mounting means comprises means pivotally mounting a first of the metal strips on the housing, means connecting a second of the metal strips to the first strip and means for adjusting the position of the first and second strips relative to the housing.
Claim 6
Dependent Claim
37 words
The razor of claim 4 wherein the housing provides an upper wall having an opening therethrough and the adjusting means comprises a threaded member extending through the upper wall into engagement with one of the metal strips.
Claim 7
Dependent Claim
34 words
The razor of claim 1 wherein the reaper member is made of an organic polymeric material having a Shore durometer hardness of about 55-70 and a coefficient of kinetic friction greater than about 0.8.
Claim 8
Dependent Claim
15 words
The razor of claim 6 wherein the coefficient of kinetic friction is greater than 1.0.
Claim 9
Dependent Claim
96 words
A razor comprising a housing having an electric motor therein; a blade having a straight sharpened edge; a reaper member having a body and plurality of blades projecting therefrom; and means mounting the reaper member for rotation about an axis parallel to the blade edge, the axis being spaced from the blade a distance substantially equal to the length of the reaper blades as measured from the axis; the reaper member being made of an organic polymeric material having a Shore durometer hardness of about 55-70 and a coefficient of kinetic friction greater than about 0.8.
Claim 10
Dependent Claim
96 words
A razor comprising a housing having an electric motor therein; a blade having a straight sharpened edge; a reaper member having a body and plurality of blades projecting therefrom; and means mounting the reaper member for rotation about an axis parallel to the blade edge, the axis being spaced from the blade a distance substantially equal to the length of the reaper blades as measured from the axis; the reaper member being made of an organic polymeric material having a Shore durometer hardness of about 55-70 and a coefficient of kinetic friction greater than about 0.8.
Claim 11
Dependent Claim
14 words
The razor of claim 8 wherein the organic polymeric material has a fabric finish.
Claim 12
Dependent Claim
13 words
The razor of claim 9 wherein the organic polymeric material is silicone rubber.
Claim 13
Dependent Claim
15 words
The razor of claim 10 wherein the coefficient of kinetic friction is above about 1.0.
