Abstract
Abstract A resilient mounting, such as used for marine engines, having a base provided with a cylindrical socket in which a resilient bushing is tightly compressed. The bushing extends above the socket at its upper end and the socket is designed so that the load on the bushing will be carried essentially in shear. A stud assembly is connected with the bushing and projects upwardly therefrom.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
216 words
A resilient mounting comprising a base having a mounting face at its lower end and having means thereon for securing it to a support, said base having a vertically extending cylindrical socket therein which is open at the top and bottom of the base, said socket having a rigid radially inwardly extending, generally horizontal, peripheral flange at its upper end, a resiliently compressible bushing tightly retained within said socket, said bushing having a generally flat bottom face and an integral extension of reduced cross section at the upper end thereof projecting upwardly through the opening defined by said peripheral flange, the junction between said extension and the portion of the bushing within said socket being defined by a generally flat, horizontally extending, annular surface on the bushing compressingly engaging the underside of said peripheral flange, a stud extending vertically upwardly through said bushing, said stud having a radial flange at its lower end compressingly engaging said flat bottom face, a downwardly dished washer fixed on said stud and bearing downwardly on the upper end of the bushing throughout the extent of the upper end face thereof and means forming a rounded annular shoulder at the lower end of said socket bearing upwardly against said flat bottom face of said bushing around the outer peripheral portion thereof.
Claim 2
Dependent Claim
216 words
A resilient mounting comprising a base having a mounting face at its lower end and having means thereon for securing it to a support, said base having a vertically extending cylindrical socket therein which is open at the top and bottom of the base, said socket having a rigid radially inwardly extending, generally horizontal, peripheral flange at its upper end, a resiliently compressible bushing tightly retained within said socket, said bushing having a generally flat bottom face and an integral extension of reduced cross section at the upper end thereof projecting upwardly through the opening defined by said peripheral flange, the junction between said extension and the portion of the bushing within said socket being defined by a generally flat, horizontally extending, annular surface on the bushing compressingly engaging the underside of said peripheral flange, a stud extending vertically upwardly through said bushing, said stud having a radial flange at its lower end compressingly engaging said flat bottom face, a downwardly dished washer fixed on said stud and bearing downwardly on the upper end of the bushing throughout the extent of the upper end face thereof and means forming a rounded annular shoulder at the lower end of said socket bearing upwardly against said flat bottom face of said bushing around the outer peripheral portion thereof.
Claim 3
Dependent Claim
34 words
A mounting as called for in claim 1 wherein said last-mentioned means comprises a ring in said socket having a rounded shoulder extending around its inner periphery at the upper end of the ring.
Claim 4
Dependent Claim
13 words
A mounting as called for in claim 1 wherein said extension is conical.
Claim 5
Dependent Claim
33 words
A mounting as called for in claim 3 wherein said washer has a diameter at least slightly smaller than the opening defined by said peripheral flange at the upper end of the socket.
Claim 6
Dependent Claim
56 words
A mounting as called for in claim 4 wherein the lower end of said extension has a diameter corresponding generally to the diameter of the opening defined by the peripheral flange at the upper end of the socket and the upper end thereof has a diameter which corresponds generally with the diameter of the dished washer.
Claim 7
Dependent Claim
25 words
A mounting as called for in claim 5 wherein the inner diameter of said ring corresponds generally with the outer diameter of said dished washer.
Claim 8
Dependent Claim

A mounting as called for in claim 1 wherein the height of the portion of the bushing within said socket is equal to about at least 35% of the diameter of the socket.
Claim 9
Dependent Claim
33 words
A mounting as called for in claim 1 wherein the height of the portion of the bushing within said socket is equal to about at least 40% of the diameter of the socket.
Claim 10
Dependent Claim
31 words
A mounting as called for in claim 7 wherein the total height of the bushing, including said extension, is equal to at least about one-half of the diameter of the bushing.
Claim 11
Dependent Claim
27 words
A mounting as called for in claim 9 wherein the height of said extension is equal to at least about one-third the total height of the bushing.
Claim 12
Dependent Claim
35 words
A mounting as called for in claim 2 wherein said ring is press fitted into the lower end of said socket and has a bottom face substantially flush with said mounting face of said base.
