Abstract
Abstract A bearing construction for the end of a flat truss having top and bottom wood chord members and inclined metallic intervening tension web members terminating in apertured load transfer flanges secured to at least one side of the chord members by toothed connector plates overlying the flanges with the teeth intermeshing the apertures and embedded in the chord members. A stress transferring channel overlies the end of the top chord and the channel web has teeth embedded into the top of the chord. The legs of the channel abut the sides of the chord under the flanges and connector plates and are apertured to intermesh with connector plate teeth extending through the load transfer flanges into the sides of the chord.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
In combination, a truss having top and bottom chord members and intervening web members, a bearing support for the end of the truss, an inclined metallic web connector having an apertured terminal flange contiguous to the side of the end portion of the top chord, and a side connector plate overlying said flange and extending over said bearing support, said side connector plate having teeth intermeshing said flange apertures and embedded in said chord, a channel bearing plate having a toothed web with its teeth embedded in the top of said top chord, and apertured legs depending from said web abutting the sides of said top chord under said apertured terminal flange and intermeshing with the teeth of said side connector plate.
Claim 2
Dependent Claim
122 words
In combination, a truss having top and bottom chord members and intervening web members, a bearing support for the end of the truss, an inclined metallic web connector having an apertured terminal flange contiguous to the side of the end portion of the top chord, and a side connector plate overlying said flange and extending over said bearing support, said side connector plate having teeth intermeshing said flange apertures and embedded in said chord, a channel bearing plate having a toothed web with its teeth embedded in the top of said top chord, and apertured legs depending from said web abutting the sides of said top chord under said apertured terminal flange and intermeshing with the teeth of said side connector plate.
Claim 3
Dependent Claim
21 words
In combination, a truss as described in claim 1, wherein the channel bearing plate is coextensive with said side connector plate.
Claim 4
Dependent Claim
35 words
In combination, a truss as described in claim 1, wherein the truss has two superposed top chord members, and the side connector plate and underlying channel legs traverse the sides of both top chord members.
Claim 5
Dependent Claim
28 words
In combination, a truss as described in claim 3, wherein there are two parallel side-by-side metallic web connectors with terminal apertured flanges overlaid by the side connector plate.
Claim 6
Dependent Claim
98 words
Bearing plate construction for the end of a top wood chord of a truss, comprising an inclined web connector having an apertured terminal flange contiguous to the side of the end portion of said top chord, a toothed side connector plate overlying said flange and having teeth intermeshing said apertures and embedded in said chord, a channel bearing plate having a toothed web with its teeth embedded in the top of said chord, and apertured legs depending from said web abutting the sides of said chord under said terminal flange and intermeshing the teeth of said side flange.
Claim 7
Dependent Claim
98 words
Bearing plate construction for the end of a top wood chord of a truss, comprising an inclined web connector having an apertured terminal flange contiguous to the side of the end portion of said top chord, a toothed side connector plate overlying said flange and having teeth intermeshing said apertures and embedded in said chord, a channel bearing plate having a toothed web with its teeth embedded in the top of said chord, and apertured legs depending from said web abutting the sides of said chord under said terminal flange and intermeshing the teeth of said side flange.
Claim 8
Dependent Claim
