Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
79 words
A housing, particularly for a gear-driven apparatus, comprising a cast peripheral housing wall having an interior surface defining inwardly of said surface an interior chamber for the components of said apparatus and consisting of a first material permitting manufacture of said wall as a casting; and at least one embedment in said peripheral wall located in its entirety behind and outwardly of said interior surface and consisting of a second material having greater strength characteristics than said first material.
Claim 2
Dependent Claim
79 words
A housing, particularly for a gear-driven apparatus, comprising a cast peripheral housing wall having an interior surface defining inwardly of said surface an interior chamber for the components of said apparatus and consisting of a first material permitting manufacture of said wall as a casting; and at least one embedment in said peripheral wall located in its entirety behind and outwardly of said interior surface and consisting of a second material having greater strength characteristics than said first material.
Claim 3
Dependent Claim
14 words
A housing as defined in claim 1, wherein said embedment is a sheet-metal insert.
Claim 4
Dependent Claim
21 words
A housing as defined in claim 1, wherein said embedment is a tubular member provided with opposite apertures intermediate its ends.
Claim 5
Dependent Claim
21 words
A housing as defined in claim 1, wherein said first material is cast aluminum, and wherein said second material is steel.
Claim 6
Dependent Claim
36 words
A housing as defined in claim 1, wherein said first material has a predetermined coefficient of thermal expansion, and wherein said second material has a coefficient of thermal expansion which at least approximates said predetermined coefficient.
Claim 7
Dependent Claim
17 words
A housing as defined in claim 1, said embedment being substantially completely embedded in said first material.
Claim 8
Dependent Claim
21 words
A housing as defined in claim 1, at least part of said embedment being substantially completely embedded in said first material.
Claim 9
Dependent Claim
20 words
A housing as defined in claim 1, wherein said second material has a greater tensile strength than said first material.
Claim 10
Dependent Claim
88 words
A housing, particularly for a gear-driven apparatus, comprising a cast peripheral housing wall defining an interior chamber for the components of said apparatus and consisting of a first material permitting manufacture of said wall as a casting; and at least one reinforcing embedment in said wall and consisting of a second material having greater strength characteristics than said first material, said embedment being a tubular member slit along a generatrix thereof and having spaced ends, and having a flange-shaped portion provided on at least one of said ends.
Claim 11
Dependent Claim
88 words
A housing, particularly for a gear-driven apparatus, comprising a cast peripheral housing wall defining an interior chamber for the components of said apparatus and consisting of a first material permitting manufacture of said wall as a casting; and at least one reinforcing embedment in said wall and consisting of a second material having greater strength characteristics than said first material, said embedment being a tubular member slit along a generatrix thereof and having spaced ends, and having a flange-shaped portion provided on at least one of said ends.
Claim 12
Dependent Claim
90 words
A housing, particularly for a gear-driven apparatus, comprising a cast peripheral housing wall defining an interior chamber for the components of said apparatus and consisting of a first material permitting manufacture of said wall as a casting; and at least one reinforcing embedment in said wall and consisting of a second material having greater strength characteristics than said first material, said wall and said embedment each having at least one registering aperture, with that in said embedment being at least equal in size and dimension to that in said wall.
Claim 13
Dependent Claim
90 words
A housing, particularly for a gear-driven apparatus, comprising a cast peripheral housing wall defining an interior chamber for the components of said apparatus and consisting of a first material permitting manufacture of said wall as a casting; and at least one reinforcing embedment in said wall and consisting of a second material having greater strength characteristics than said first material, said wall and said embedment each having at least one registering aperture, with that in said embedment being at least equal in size and dimension to that in said wall.
Claim 14
Dependent Claim
94 words
A housing, particularly for a gear-driven apparatus, comprising a cast peripheral housing wall defining an interior chamber for the components of said apparatus and consisting of a first material permitting manufacture of said wall as a casting; and at least one reinforcing embedment in said wall and consisting of a second material having greater strength characteristics than said first material, said embedment being provided with apertures filled by the material of said wall whereby the latter and said embedment are interlocked against forces tending to cause them to perform movements relative to one another.
Claim 15
Dependent Claim
94 words
A housing, particularly for a gear-driven apparatus, comprising a cast peripheral housing wall defining an interior chamber for the components of said apparatus and consisting of a first material permitting manufacture of said wall as a casting; and at least one reinforcing embedment in said wall and consisting of a second material having greater strength characteristics than said first material, said embedment being provided with apertures filled by the material of said wall whereby the latter and said embedment are interlocked against forces tending to cause them to perform movements relative to one another.
