Abstract
Abstract A device (10;50) comprising an armature (12;80) movable in a first and a second direction; an obstruction for (20;22;60;74) for providing a motion stop in at least the first direction; an electromagnetic and return spring (18;28;60;140) for moving said armature in the first and second directions; and a damper attached to and movable with said armature for dissipating energy from the collision of the armature with the motion stop.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
92 words
A device comprising an armature movable in a first and a second direction; means for providing a motion stop in at least said first direction; means for moving said armature in said first and said second directions; and means, attached to and movable with said armature for damping the motion of said armature by dissipating energy from a collision of said armature with said stop means wherein said damping means comprises a damper including an elastomeric sheath positioned about said armature and a weight attached to the outer surface of said sheath.
Claim 2
Independent Claim
92 words
A device comprising an armature movable in a first and a second direction; means for providing a motion stop in at least said first direction; means for moving said armature in said first and said second directions; and means, attached to and movable with said armature for damping the motion of said armature by dissipating energy from a collision of said armature with said stop means wherein said damping means comprises a damper including an elastomeric sheath positioned about said armature and a weight attached to the outer surface of said sheath.
Claim 3
Dependent Claim
21 words
The device as defined in claim 1 wherein said moving means includes an electric coil and wherein said weight is nonmagnetic.
Claim 4
Dependent Claim
48 words
The device as defined in claim 2 wherein said armature comprises a necked-down portion and includes opposingly positioned, axially spaced, shoulders; said elastomeric sheath received onto said necked down position and including ends engagably mating said shoulders; and said weight comprising a cylindrical member positioned about said sheath.
Claim 5
Dependent Claim
18 words
The device as defined in claim 3 wherein said weight comprises a cylindrical ring including a split wall.
Claim 6
Dependent Claim
16 words
The device as defined in claim 3 wherein said weight is affixed to said elastomeric sheath.
Claim 7
Dependent Claim
32 words
The device as defined in claim 1 wherein said damping means comprises a plurality elastomeric rings positioned about and axially spaced along said armature; and a weight, compressively loaded onto said rings.
Claim 8
Dependent Claim
35 words
The device as defined in claim 6 wherein said weight comprises two semi-cylindrical sections, opposingly positioned onto said rings and wherein compressive loading is derived from a plurality of spring rings received about said sections.
Claim 9
Dependent Claim
21 words
The device as defined in claim 7 wherein said sections substantially envelop approximately one half of the circumference of said armature.
Claim 10
Dependent Claim
37 words
The device as defined in claim 8 wherein said armature includes a necked down portion including two spaced, shoulders, and wherein said elastomeric rings are compressively loaded by said sections against a respective one of said shoulders.
Claim 11
Dependent Claim
25 words
The device as defined in claim 9 wherein such sections, proximate said elastomeric ring, include means for receiving and securing one of said elastomeric rings.
Claim 12
Independent Claim
101 words
A device comprising an armature movable in a first and a second direction; means for providing a motion stop in at least said first direction; means for moving said armature in said first and said second directions; and means, attached to and movable with said armature for damping the motion of said armature by dissipating energy from a collision of said armature with said stop means wherein said damping means comprises a spring supported member including a first surface slidably engaging a surface of the armature wherein energy is dissipated as said first surface co-acts with the surface of the armature.
Claim 13
Independent Claim
101 words
A device comprising an armature movable in a first and a second direction; means for providing a motion stop in at least said first direction; means for moving said armature in said first and said second directions; and means, attached to and movable with said armature for damping the motion of said armature by dissipating energy from a collision of said armature with said stop means wherein said damping means comprises a spring supported member including a first surface slidably engaging a surface of the armature wherein energy is dissipated as said first surface co-acts with the surface of the armature.
Claim 14
Independent Claim
73 words
A device comprising an armature adapted to be moved in a first and a second direction relative to a motion stop; and means, attached to and movable with said armature, for damping the motion of said armature by dissipating energy of a collision of said armature with said motion stop wherein said damping means comprises an elastomeric sheath positioned about said armature and a weight attached to the outer surface of said sheath.
Claim 15
Independent Claim
73 words
A device comprising an armature adapted to be moved in a first and a second direction relative to a motion stop; and means, attached to and movable with said armature, for damping the motion of said armature by dissipating energy of a collision of said armature with said motion stop wherein said damping means comprises an elastomeric sheath positioned about said armature and a weight attached to the outer surface of said sheath.
Claim 16
Dependent Claim
46 words
The device as defined in claim 12 wherein said armature comprises a necked-down portion and includes opposingly positioned, axially-spaced, shoulders; said elastomeric sheath received onto said necked-down portion and including ends engagably mating said shoulders; and said weight comprising a cylindrical member positioned about said sheath.
Claim 17
Dependent Claim

Claim 20
Dependent Claim
35 words
The device as defined in claim 7 wherein said weight comprises two semi-cylindrical sections, opposingly positioned onto said rings and wherein compressive loading is derived from a plurality of spring rings received about said sections.
Claim 21
Dependent Claim
21 words
The device as defined in claim 17 wherein said sections substantially envelop approximately one half of the circumference of said armature.
Claim 22
Dependent Claim
37 words
The device as defined in claim 18 wherein said armature includes a necked down portion including two spaced, shoulders, and wherein said elastomeric rings are compressively loaded by said sections against a respective one of said shoulders.
