Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
194 words
A captive vibration isolation device, comprising: a first resiLient element with an inner and an outer end face; a longitudinal bore through said first resilient element; a second resilient element substantially identical to said first resilient, said first and second resilient elements mutually engaged end to end to form a resilient unit symetrical about the plane of engagement; an end cap; a longitudinal preload spool within said bore, said spool having a first and second end, said first end being flared for fixed engagement with the outer end of said second resilient element, said preload spool end being threaded to engage said end cap; a first seismic mass attached to said first resilient element; a second seismic mass attached to said second resilient element; a pair of spacer yokes rigidly engaging said first and second seismic masses to form a loose noncontacting enclosure surrounding the engaged ends of said first and second resilient elements; a first support plate engaging said first resilient element and partially within said spacer yokes; and, a second support plate substantially identical to said first support plate and mutually engaging said first support plate and engaging said second resilient element.
Claim 2
Dependent Claim
194 words
A captive vibration isolation device, comprising: a first resiLient element with an inner and an outer end face; a longitudinal bore through said first resilient element; a second resilient element substantially identical to said first resilient, said first and second resilient elements mutually engaged end to end to form a resilient unit symetrical about the plane of engagement; an end cap; a longitudinal preload spool within said bore, said spool having a first and second end, said first end being flared for fixed engagement with the outer end of said second resilient element, said preload spool end being threaded to engage said end cap; a first seismic mass attached to said first resilient element; a second seismic mass attached to said second resilient element; a pair of spacer yokes rigidly engaging said first and second seismic masses to form a loose noncontacting enclosure surrounding the engaged ends of said first and second resilient elements; a first support plate engaging said first resilient element and partially within said spacer yokes; and, a second support plate substantially identical to said first support plate and mutually engaging said first support plate and engaging said second resilient element.
Claim 3
Dependent Claim
24 words
A captive vibration isolation device, as in claim 1, wherein: said resilient unit engages said preload spool only near the ends of said spool.
Claim 4
Dependent Claim
32 words
A device as in claim 1 wherein said seismic mass is concentrically mounted with respect to the longitudinal axis of the preload spool and symmetrically mounted with respect to said support plates.
Claim 5
Dependent Claim
135 words
A captive vibration device, comprising: a first and second resilient means to isolate a vibrating mechanical device; a preload spool means centrally located within each of said first and second resilient means for engagement with a vibrating mechanical device and capable of simultaneously longitudinally compressing said first and second resilient means; a first and second external seismic mass whose combined center of mass is located at the combined center of vibration of said first and second resilient means said first and second seismic mass engaging the surface of said first and second resilient element; a pair of spacer yoke means for separating and rigidly connecting said first and second seismic mass means; and a first and second support plate means for engaging the combined resilient means at its center to suspend a vibrating mechanical device.
Claim 6
Dependent Claim
135 words
A captive vibration device, comprising: a first and second resilient means to isolate a vibrating mechanical device; a preload spool means centrally located within each of said first and second resilient means for engagement with a vibrating mechanical device and capable of simultaneously longitudinally compressing said first and second resilient means; a first and second external seismic mass whose combined center of mass is located at the combined center of vibration of said first and second resilient means said first and second seismic mass engaging the surface of said first and second resilient element; a pair of spacer yoke means for separating and rigidly connecting said first and second seismic mass means; and a first and second support plate means for engaging the combined resilient means at its center to suspend a vibrating mechanical device.
