Shearing head for dry shaver

Claim 2

A shearing head for a dry shaving apparatus having an oscillatory driving member, comprising in combination, a shearing head housing, a short hair shearing unit operatively supported by said housing, a long hair shearing unit disposed adjacent said short hair shearing unit and pivotAlly connected with relation to said housing for angular adjustment between two extreme positions including an elevated position near the top level of said short hair shearing unit and, respectively, a normal position at a level lower than said elevated position, means coupling said long hair shearing unit to said driving member for driving said unit in either one of said extreme positions and intermediate thereof.

Claim 3

A shearing head for a dry shaving apparatus, comprising in combination, a shearing head housing, a short hair shearing unit operatively supported by said housing, a long hair shearing unit disposed adjacent said short hair shearing unit and movably connected with relation to said housing for movement between two extreme positions including an elevated position near the top level of said short hair shearing unit and, respectively, a normal position at a level lower than said elevated position, a tiltable support member having a longitudinal cross-bar situated adjacent a bottom portion of said short hair shearing unit, said long hair shearing unit being supported on said support member, perpendicular arms endwise mounted on said cross-bar and extending along the inner surface of said housing and being pivotally suspended with relation therefrom.

Claim 4

A shearing head for a dry shaving apparatus, comprising in combination, a shearing head housing, a short hair shearing unit operatively supported by said housing, a long hair shearing unit disposed adjacent said short hair shearing unit and movably connected with relation to said housing for movement between two extreme positions including an elevated position near the top level of said short hair shearing unit and, respectively, a normal position at a level lower than said elevated position, a tiltable support member having a longitudinal cross-bar situated adjacent a bottom portion of said short hair shearing unit, said long hair shearing unit being supported on said support member, perpendicular arms endwise mounted on said cross-bar and extending along the inner surface of said housing and being pivotally suspended with relation therefrom.

Claim 5

A shearing head according to claim 2, reciprocating driving member, said long hair shearing unit comprising a stationary upper shearing member secured to said cross-bar, and a reciprocating lower shearing member slidably supported near the top surface of said cross-bar, and a fork-shaped coupling in driven relation from said driving member.

Claim 6

A shearing head according to claim 2 wherein said arms are provided with resilient arresting means for locking said tiltable support member, and thereby said long hair shearing unit, in any desired operative position between said extreme positions.

Claim 7

A shearing head according to claim 3 wherein the distance between said shearing elements and the axis of tilting of said supporting member exceeds the distance between said shearing members and the longitudinal plane of symmetry of said short hair shearing unit.

Claim 8

A shearing head according to claim 4, said housing having sidewalls and defining bores, said resilient arresting means including elongated leaf springs secured at one end thereof to said arms and provided at the other end with locking pins, said locking pins engaging said bores.

Claim 9

A shearing head for a dry shaving apparatus, comprising in combination, a shearing head housing, a short hair shearing unit operatively supported by said housing, a long hair shearing unit disposed adjacent said short hair shearing unit and movably connected with relation to said housing for movement between two extreme positions including an elevated position near the top level of said short hair shearing unit and, respectively, a normal position at a level lower than said elevated position, a displaceable support member comprising a longitudinal cross-bar adjacent a bottom portion of said short hair shearing unit, said long hair shearing unit being supported on said support member, perpendicular arms endwise mounted on said cross-bar and extending near the inner surface of said housing, guiding grooves defined in said inner surface, and groove engaging means arranged on said arms operable for engaging said guiding grooves thereby to guide said long hair shearing unit in its movements.

Claim 10

A shearing head for a dry shaving apparatus, comprising in combination, a shearing head housing, a short hair shearing unit operatively supported by said housing, a long hair shearing unit disposed adjacent said short hair shearing unit and movably connected with relation to said housing for movement between two extreme positions including an elevated position near the top level of said short hair shearing unit and, respectively, a normal position at a level lower than said elevated position, a displaceable support member comprising a longitudinal cross-bar adjacent a bottom portion of said short hair shearing unit, said long hair shearing unit being supported on said support member, perpendicular arms endwise mounted on said cross-bar and extending near the inner surface of said housing, guiding grooves defined in said inner surface, and groove engaging means arranged on said arms operable for engaging said guiding grooves thereby to guide said long hair shearing unit in its movements.
