Abstract
Abstract A suspension system provides a motion damping mounting for carrying a record playback machine comprising a plurality of damping ring assemblies, each having an elastic ring for fastening between a machine and a support, the rings being flattened when secured such that opposite segments of each ring extend substantially straight and parallel such that a component of stress applied to the machine in the direction of the straight segments produces limited rolling movement of a flattened ring, which damps motion of the playback machine in the direction of the straight segments of the flattened ring, the flattened ring also damping motion of the machine vertically and laterally relative to the direction of the straight segments. According to this invention, the damping assembly includes a ring and mounting plates or clips and fasteners for securing the ring to the machine or the support.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
210 words
A motion damping suspension system for mounting a machine, such as a record playback machine, vertically above a movable support comprising: movable support members providing substantially flat, horizontal supporting surfaces; machine mounting members providing substantially flat mounting surfaces substantially parallel to and above said supporting surfaces; a plurality of elastic rings secured between said machine mounting surfaces and said support supporting surfaces with said elastic rings in flattened condition between said surfaces and the axis of each ring arranged substantially horizontally and opposite segments of each ring adjacent said mounting and supporting surfaces extending substantially horizontally; means for securing a portion of one of said horizontally extending segments of each ring to the machine and a portion of the other of said horizontally extending segments of each ring to the support to support the weight of the machine by compressing vertically extending segments of each ring such that stress applied to the machine having a component in the direction of the horizontal segments of a flattened ring produces limited rolling movement of said horizontally extending segments of the flattened ring along said mounting surfaces and said supporting surfaces which damps motion of the machine; said flattened ring also damping motion of the machine vertically and laterally relative to said direction.
Claim 2
Dependent Claim
210 words
A motion damping suspension system for mounting a machine, such as a record playback machine, vertically above a movable support comprising: movable support members providing substantially flat, horizontal supporting surfaces; machine mounting members providing substantially flat mounting surfaces substantially parallel to and above said supporting surfaces; a plurality of elastic rings secured between said machine mounting surfaces and said support supporting surfaces with said elastic rings in flattened condition between said surfaces and the axis of each ring arranged substantially horizontally and opposite segments of each ring adjacent said mounting and supporting surfaces extending substantially horizontally; means for securing a portion of one of said horizontally extending segments of each ring to the machine and a portion of the other of said horizontally extending segments of each ring to the support to support the weight of the machine by compressing vertically extending segments of each ring such that stress applied to the machine having a component in the direction of the horizontal segments of a flattened ring produces limited rolling movement of said horizontally extending segments of the flattened ring along said mounting surfaces and said supporting surfaces which damps motion of the machine; said flattened ring also damping motion of the machine vertically and laterally relative to said direction.
Claim 3
Dependent Claim
20 words
A system according to claim 1 wherein the axes of said plurality of elastic rings are parallel to each other.
Claim 4
Dependent Claim
30 words
A system according to claim 1 wherein a plate and a fastener are provided for securing each of the opposite segments of a ring to a machine or a support.
Claim 5
Dependent Claim
27 words
A system according to claim 1 wherein a mounting clip is provided for securing each of the segments of a ring to a machine or a support.
Claim 6
Dependent Claim
106 words
A system according to claim 1 wherein a mounting clip is provided for securing each of the vertically opposite segments of a ring to a machine or a support, said mounting clip having an elongated, substantially straight portion adapted to fit around one of said vertically opposite segments of a ring and hold said segment against a mounting surface of a machine or a supporting surface of a support, said mounting clip having flexible hooked arms bendable toward each other to fit through an opening in a machine or a support and to spring back and interengage with edges of the opening to secure the ring.
Claim 7
Dependent Claim
101 words
A damping ring assembly for mounting a playback machine on a support comprising: a ring of elastic material; a pair of mounting clips adapted to fit around opposite segments of said ring; said mounting clips each having a straight body portion with a U-shaped cross-section, the body portion having flexible hooked arms bendable toward each other and squeezing the associated ring to fit through an opening in a support or a machine and to spring back and be restored by their resilience and interengage with edges of said opening to secure the mounting clip and ring between the machine and support.
Claim 8
Dependent Claim
101 words
A damping ring assembly for mounting a playback machine on a support comprising: a ring of elastic material; a pair of mounting clips adapted to fit around opposite segments of said ring; said mounting clips each having a straight body portion with a U-shaped cross-section, the body portion having flexible hooked arms bendable toward each other and squeezing the associated ring to fit through an opening in a support or a machine and to spring back and be restored by their resilience and interengage with edges of said opening to secure the mounting clip and ring between the machine and support.
Claim 9
Dependent Claim
38 words
A damping ring assembly according to claim 6 wherein said straight body portion of a clip includes end sections for engaging an adjacent face of a support or a machine and a central section having said hooked arms.
Claim 10
Dependent Claim
59 words
A system according to claim 1 for a machine having a certain longitudinal axis and said plurality of rings are provided for mounting with the horizontally extending segments thereof extending at an angle inclined to said longitudinal axis of said machine to damp motion of said machine caused by stress applied in the direction of the horizontally extending segments.
