Abstract
Abstract Vibration absorbing means installed between a structure and its support, the structure being of a size such as a house, and the support being means such as a foundation wall. In certain applications, a floor or similar member may be resiliently supported with respect to the remainder of the building to insulate the floor from vibration in the building, or conversely to decrease the vibration from equipment on the floor to the rest of the building. The structure is firmly connected to its support through vibration-absorbing means and no rigid vibrationtransmitting connection is necessary between the two.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
150 words
A resilient supporting connection for a structure which includes: a rigid support; a resilient, vibration-insulating cushion on said support; a sill forming a part of said structure, bearing against said cushion and supported thereby; unitary connecting means rigidly attached at one end to said support, said connecting means extending through said resilient vibration insulating cushion and through said sill to hold said sill and support together; and resilient attaching means including resilient annular vibrationinsulating means securing said other end of said connecting means to said sill, said annular means surrounding said connecting means, bearing against said sill and spacing said connecting means from said sill, whereby said sill is vibration-insulated from said support and from said connecting means, said annular means comprising a flanged cylindrical grommet means, said flange overlying and being urged by said connecting means against said sill, and spring means between said connecting means and said grommet.
Claim 2
Dependent Claim
150 words
A resilient supporting connection for a structure which includes: a rigid support; a resilient, vibration-insulating cushion on said support; a sill forming a part of said structure, bearing against said cushion and supported thereby; unitary connecting means rigidly attached at one end to said support, said connecting means extending through said resilient vibration insulating cushion and through said sill to hold said sill and support together; and resilient attaching means including resilient annular vibrationinsulating means securing said other end of said connecting means to said sill, said annular means surrounding said connecting means, bearing against said sill and spacing said connecting means from said sill, whereby said sill is vibration-insulated from said support and from said connecting means, said annular means comprising a flanged cylindrical grommet means, said flange overlying and being urged by said connecting means against said sill, and spring means between said connecting means and said grommet.
Claim 3
Dependent Claim
24 words
A connection as defined in claim 1, wherein said spring means comprises leaf spring means within said cylindrical grommet and engaging said connecting means.
Claim 4
Dependent Claim
26 words
A connection as defined in claim 1, wherein said spring means comprises a spring washer between the upper surface of said flange and said connecting means.
