Abstract
Abstract Apparatus for mounting within a case which represents the vibrating load, includes an electric motor assembly and a suspension bracket to which the case is rigidly attached. The motor includes a relatively heavy housing which defines a magnetic stator structure, and a relatively light reciprocating armature structure. The armature oscillates lever arms pivotally connected to the motor stator; with the lever arms being coupled to the suspension bracket to effect relative reciprocating movement between the suspension bracket and motor stator.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
105 words
Vibratory apparatus comprising: a motor including a housing and a drive member reciprocable relative to said housing; lever arm means pivotally mounted on said motor housing; means coupling said motor drive member to said lever arm means for oscillating said lever arm means relative to said motor housing; a suspension frame guided on said motor housing for reciprocating movement relative hereto; said frame being adapted to mount a load member, and defining with said load member the vibrating load of said apparatus; and means coupling said suspension frame to said lever arm means for effecting reciprocating movement of said frame relative to said motor housing.
Claim 2
Dependent Claim
105 words
Vibratory apparatus comprising: a motor including a housing and a drive member reciprocable relative to said housing; lever arm means pivotally mounted on said motor housing; means coupling said motor drive member to said lever arm means for oscillating said lever arm means relative to said motor housing; a suspension frame guided on said motor housing for reciprocating movement relative hereto; said frame being adapted to mount a load member, and defining with said load member the vibrating load of said apparatus; and means coupling said suspension frame to said lever arm means for effecting reciprocating movement of said frame relative to said motor housing.
Claim 3
Dependent Claim
23 words
Vibratory apparatus as set forth in claim 1 including a casing fixed to said frame, defining therewith the vibrating load of said apparatus.
Claim 4
Dependent Claim
47 words
Vibratory apparatus as set forth in claim 2 wherein the weight of said motor drive member is small relative to the weight of said motor housing; and wherein the weight of said suspension frame and casing is of the order of the weight of said motor housing.
Claim 5
Dependent Claim
45 words
Vibratory apparatus as set forth in claim 1 wherein said lever arm means defines a relatively long lever arm between said motor housing pivot and said drive member coupling and a relatively short lever arm between said motor housing pivot and said suspension frame coupling.
Claim 6
Dependent Claim
45 words
Vibratory apparatus as set forth in claim 3 wherein said lever arm means defines a relatively long Lever arm between said motor housing pivot and said drive member coupling, and a relatively short lever arm between said motor housing pivot and said suspension frame coupling.
Claim 7
Dependent Claim
54 words
Vibratory apparatus as set forth in claim 1 wherein said motor is an electric motor; said motor housing including magnetic stator, and said motor drive member including an armature guided for reciprocating movement within said stator; and means coupling said motor housing and said drive member to limit the relative excursion of said armature.
Claim 8
Dependent Claim
102 words
Vibratory apparatus as set forth in claim 1 wherein said motor is an electrically operated motor; said motor housing including a magnetic stator structure, and said motor drive member including a magnetically actuated armature structure guided centrally within said stator structure for relative reciprocating movement; a pair of transverse arms pivotally connected at their inner ends to said motor drive member; means on said motor housing pivotally supporting said arms at points intermediate the ends of said arms equidistant from said drive member pivot; said suspension frame partially enclosing said motor housing, and having means pivotally connected to the outer ends thereof.
Claim 9
Dependent Claim
68 words
Vibratory apparatus as set forth in claim 7 said transverse arms defining relatively long lever arms between said motor housing pivots and said drive member pivot and defining relatively short lever arms between said motor housing pivots and said frame pivots, whereby the excursion of said frame relative to said motor housing is substantially less than the excursion of said motor drive member relative to said motor housing.
