Claim 1
Independent Claim
153 words
A roof gutter assembly comprising a trough member, said trough member having a front wall, a back wall and a floor joined to the lower edges of said front wall and said back wall; a tongue formed along the upper edge of said front wall; a facia plate having a recess being removably received in said recess, said tongue to thereby removably mount said facia plate to said front wall, said facia plate forming an upward extension of said front wall when mounted to said front wall; a recess formed along the lower edge of said front wall; a facia plate having a tongue, said recess receiving said tongue to removably mount said last mentioned facia plate to said front wall, said last mentioned facia plate forming a lower extension of said front wall when mounted to said front wall; and recess means formed in said back wall for receiving a soffit member.
Claim 2
Dependent Claim
153 words
A roof gutter assembly comprising a trough member, said trough member having a front wall, a back wall and a floor joined to the lower edges of said front wall and said back wall; a tongue formed along the upper edge of said front wall; a facia plate having a recess being removably received in said recess, said tongue to thereby removably mount said facia plate to said front wall, said facia plate forming an upward extension of said front wall when mounted to said front wall; a recess formed along the lower edge of said front wall; a facia plate having a tongue, said recess receiving said tongue to removably mount said last mentioned facia plate to said front wall, said last mentioned facia plate forming a lower extension of said front wall when mounted to said front wall; and recess means formed in said back wall for receiving a soffit member.
Claim 3
Dependent Claim
25 words
The assembly as defined in claim 1 and including a soffit member removably carried in said recess means and extending outwardly from said back wall.
Claim 4
Dependent Claim
43 words
The assembly as defined in claim 1 and in which said last mentioned facia plate is provided with recess means, and a soffit member removably mounted in said recess means to extend away from said last mentioned facia plate parallel to said floor.
Claim 5
Dependent Claim
58 words
The assembly as defined in claim 1 and in which said first mentioned facia plate includes a tongue formed along its upper edge, said tongue being receivable in said recess along the lower edge of said front wall whereby said facia plate may be removably mounted to either the upper or the lower edge of said front wall.
Claim 6
Dependent Claim
61 words
A system according to claim 1 wherein the trough member has a downwardly directed internal hook flange extending longitudinally of its front wall at the top edge thereof and an internal recess extending longitudinally of its back wall adjacent the bottom thereof and a supporting bracket having portions engaging said flange and extending into said recess to support said trough member.
Claim 7
Dependent Claim
67 words
The assembly as defined in claim 1 and including a coupling, said trough and coupling being complementarily shaped such that an end portion of one may be entered longitudinally into an end portion of the other with their contiguous surfaces in close conformity each to each; said surfaces being shaped to interlock to prevent separation of the trough member and the coupling except in the longitudinal direction.
Claim 8
Dependent Claim
26 words
A system according to claim 6 wherein said surfaces are so shaped by means of dove-tailed ribs on one and complementary dove-tailed grooves in the other.
