Abstract
Abstract A resilient mounting assembly adapted for use in mounting a vibratory frame relative to a supporting frame in vibratory apparatus comprises a generally rigid cup-shaped member and a generally flexible cup-shaped member which is open towards the rigid member and cooperates with the rigid member to define therewith an airtight space containing air under pressure to provide said flexible member with resilience.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
192 words
In vibratory apparatus of the kind specified comprising a supporting frame (16) and a vibratory frame (11), the improvement comprising the combination of: at least three support members (29) projecting from one frame (16) towards the other frame (11); and at least three spaced-apart resilient mounting assemblies (12) mounting said vibratory frame (11) on said supporting frame (16), each mounting assembly (12) being associated with a respective one of said support members (29) and each mounting assembly (12) including: a generally rigid member (22) mounted to said other frame (11); and a generally cup-shaped flexible member (24) mounted to said one frame (16), the cup shape being open toward said rigid member (22) and cooperating with said rigid member (22) to define therewith a fluidtight space adapted to contain a fluid under pressure to provide said flexible member (24) with resilience, said flexible member (24) having in all conditions thereof an externally reentrant portion (32) which receives one of said support members (29) and an outer substantially cylindrical wall (34) or reduced cross section so that the majority of the flexing of said flexible member (24) occurs in said cylindrical wall (34).
Claim 2
Dependent Claim
192 words
In vibratory apparatus of the kind specified comprising a supporting frame (16) and a vibratory frame (11), the improvement comprising the combination of: at least three support members (29) projecting from one frame (16) towards the other frame (11); and at least three spaced-apart resilient mounting assemblies (12) mounting said vibratory frame (11) on said supporting frame (16), each mounting assembly (12) being associated with a respective one of said support members (29) and each mounting assembly (12) including: a generally rigid member (22) mounted to said other frame (11); and a generally cup-shaped flexible member (24) mounted to said one frame (16), the cup shape being open toward said rigid member (22) and cooperating with said rigid member (22) to define therewith a fluidtight space adapted to contain a fluid under pressure to provide said flexible member (24) with resilience, said flexible member (24) having in all conditions thereof an externally reentrant portion (32) which receives one of said support members (29) and an outer substantially cylindrical wall (34) or reduced cross section so that the majority of the flexing of said flexible member (24) occurs in said cylindrical wall (34).
Claim 3
Dependent Claim
20 words
Apparatus according to claim 1 wherein said rigid member (22) is cup-shaped and is open towards said flexible member (24).
Claim 4
Dependent Claim
15 words
Apparatus according to claim 1 wherein said fluidtight space is adapted to contain a gas.
Claim 5
Dependent Claim
21 words
Apparatus according to claim 1 wherein each mounting assembly the rigid member (22) is located generally above the flexible member (24).
Claim 6
Dependent Claim
32 words
Apparatus according to claim 1 wherein said supporting frame (16) comprises a plurality of upright bracing members (16c) and said at least three support members (29) are extensions of said bracing members.
