Abstract
Abstract A razor including a body, a blade having a sharp cutting edge fixedly mounted on the body, a guard mounted on the body for movement relative to the body and the blade, and a motor for imparting movement to the guard. The motor includes at least one coil which drives the guard directly or through a tuned reed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
108 words
A razor which is usable with a blade having a sharp cutting edge, said razor comprising: a body, at least a portion of said body being adapted to be manually grasped to allow manual movement of the razor; means for mounting the blade on the body with the sharp cutting edge exposed and with the blade being fixed against reciprocation relative to said body; a guard having a plurality of openings therein; means for mounting said guard on said body for reciprocatory movement relative to said body; and motor means for imparting said reciprocatory movement to said guard whereby the guard can move the hair to be cut.
Claim 2
Dependent Claim
108 words
A razor which is usable with a blade having a sharp cutting edge, said razor comprising: a body, at least a portion of said body being adapted to be manually grasped to allow manual movement of the razor; means for mounting the blade on the body with the sharp cutting edge exposed and with the blade being fixed against reciprocation relative to said body; a guard having a plurality of openings therein; means for mounting said guard on said body for reciprocatory movement relative to said body; and motor means for imparting said reciprocatory movement to said guard whereby the guard can move the hair to be cut.
Claim 3
Dependent Claim
23 words
A razor as defined in claim 1 wherein said guard is reciprocated along a path which is generally parallel to said cutting edge.
Claim 4
Dependent Claim
101 words
A razor as defined in claim 1 wherein said blade mounting means includes a plate fixed to said body and adapted to overlie at least a portion of the blade and a pair of clips fixed to said body and adapted to underlie the opposite end portions of the blade whereby the blade is clamped between said plate and said clips, said razor including a guard member, said guard member including said guard, said guard member lying intermediate said clips with sufficient clearance between said clips and guard member to allow the guard member to reciprocate longitudinally of the cutting edge.
Claim 5
Dependent Claim
44 words
A razor as defined in claim 1 wherein said motor means includes a segment of magnetic material drivingly associated with said guard and coil means energizable to provide an alternating flux field which cooperates with said segment to reciprocate said segment and said guard.
Claim 6
Dependent Claim
29 words
A razor as defined in claim 4 including a guard member, said guard member including said guard and said segment, said segment being on the exterior of said body.
Claim 7
Dependent Claim
67 words
A razor as defined in claim 4 wherein said segment includes a deflectable element of magnetic material, means for attaching said deflectable element adjacent one end thereof to said body whereby said element can oscillate, means for drivingly interrelating said deflectable element adjacent the other end thereof to said guard, said alternating flux field cooperating with said deflectable element to reciprocate said deflectable element and said guard.
Claim 8
Dependent Claim
18 words
A razor as defined in claim 6 wherein said means for drivingly interrelating includes a resilient deformable member.
Claim 9
Dependent Claim
25 words
A razor as defined in claim 6 wherein said deflectable element is tuned to resonate at substantially the speed at which the guard is reciprocated.
Claim 10
Dependent Claim
171 words
A razor which is usable with a blade member having a sharp cutting edge, said razor comprising: a body, at least a portion of said body being adapted to be manually grasped to allow manual movement of the razor; first means for mounting the blade member on the body with the sharp cutting edge exposed and with the blade being fixed against reciprocation; a guard member including a guard; second means for mounting said guard member on said body, said guard member being mounted for reciprocatory movement relative to said body in a direction generally parallel to the cutting edge when the blade is mounted by said first means, said guard being adjacent said cutting edge when the blade is mounted by said first means; said guard member being constructed at least in part of magnetic material; and coil means carried by said body and energizable to provide an alternating flux field which cooperates with the magnetic material of said guard member to reciprocate said guard member relative to said body.
Claim 11
Dependent Claim
171 words
A razor which is usable with a blade member having a sharp cutting edge, said razor comprising: a body, at least a portion of said body being adapted to be manually grasped to allow manual movement of the razor; first means for mounting the blade member on the body with the sharp cutting edge exposed and with the blade being fixed against reciprocation; a guard member including a guard; second means for mounting said guard member on said body, said guard member being mounted for reciprocatory movement relative to said body in a direction generally parallel to the cutting edge when the blade is mounted by said first means, said guard being adjacent said cutting edge when the blade is mounted by said first means; said guard member being constructed at least in part of magnetic material; and coil means carried by said body and energizable to provide an alternating flux field which cooperates with the magnetic material of said guard member to reciprocate said guard member relative to said body.
Claim 12
Dependent Claim
68 words
A razor as defined in claim 9 wherein said body has an upper end portion, said coil means being carried by said upper end portion, said guard member overlying said upper end portion, said guard member having tabs at the opposite ends thereof which overlie the opposite ends of the upper portion, and said tabs including magnetic material cooperable with said alternating flux field to reciprocate said guard.
Claim 13
Dependent Claim
116 words
A combination comprising: a body, at least a portion of said body being adapted to be manually grasped to allow manual movement of the body; a blade having a sharp cutting edge; means for mounting the blade on the body with the sharp cutting edge exposed and with the blade being fixed against reciprocation relative to said body; a guard having a plurality of openings therein; means for mounting said guard on said body for reciprocatory movement relative to said body and said blade, said openings being adjacent said cutting edge; and motor means for imparting said reciprocatory movement to said guard whereby the guard can move the hair to be cut across the cutting edge.
Claim 14
Dependent Claim
116 words
A combination comprising: a body, at least a portion of said body being adapted to be manually grasped to allow manual movement of the body; a blade having a sharp cutting edge; means for mounting the blade on the body with the sharp cutting edge exposed and with the blade being fixed against reciprocation relative to said body; a guard having a plurality of openings therein; means for mounting said guard on said body for reciprocatory movement relative to said body and said blade, said openings being adjacent said cutting edge; and motor means for imparting said reciprocatory movement to said guard whereby the guard can move the hair to be cut across the cutting edge.
