Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
145 words
A member adapted to form a machinery cover, or a part of such a cover divided at a zone spaced from means for its attachment to the machinery to provide two components which are separated by mutual linear movement to form an intervening narrow gap with marginal portions of the components at each side of the gap respectively, at least one of the components being provided with one or more keying apertures extending through the said marginal portion in a direction substantially at right angles to the direction of said linear movement, the components being connected together and insulated from mutual vibration transmission by a band of resilient natural or synthetic plastics material which fills the gap and overlaps and is bonded to the marginal portion of the components on either side of the gap and extends to fill the said keying aperture or apertures.
Claim 2
Dependent Claim
145 words
A member adapted to form a machinery cover, or a part of such a cover divided at a zone spaced from means for its attachment to the machinery to provide two components which are separated by mutual linear movement to form an intervening narrow gap with marginal portions of the components at each side of the gap respectively, at least one of the components being provided with one or more keying apertures extending through the said marginal portion in a direction substantially at right angles to the direction of said linear movement, the components being connected together and insulated from mutual vibration transmission by a band of resilient natural or synthetic plastics material which fills the gap and overlaps and is bonded to the marginal portion of the components on either side of the gap and extends to fill the said keying aperture or apertures.
Claim 3
Dependent Claim
24 words
A member according to claim 1 wherein the plastics material is rubber which rubber has been expanded in size to fill the said gap.
Claim 4
Dependent Claim
28 words
A member according to claim 1 wherein the said components have a plurality of said keying apertures, the keying apertures on the respective coMponents being in staggered relationship.
Claim 5
Dependent Claim
113 words
In machinery, a member forming a cover therefor, means for attachment of the member to the machinery, a part of the cover divided at a zone spaced from said attachment means and thereby providing two components having inside and outside marginal surfaces, the divided components being separated by a narrow gap, and each component being provided with at least one keying aperture extending therethrough, the components being connected together by a band of rubber which has been expanded in size to fill the said gap and keying apertures and which band overlaps and is bonded to the marginal surfaces of the inside and outside of the components on either side of the gap.
Claim 6
Dependent Claim
113 words
In machinery, a member forming a cover therefor, means for attachment of the member to the machinery, a part of the cover divided at a zone spaced from said attachment means and thereby providing two components having inside and outside marginal surfaces, the divided components being separated by a narrow gap, and each component being provided with at least one keying aperture extending therethrough, the components being connected together by a band of rubber which has been expanded in size to fill the said gap and keying apertures and which band overlaps and is bonded to the marginal surfaces of the inside and outside of the components on either side of the gap.
