Abstract
Abstract A truss having parallel wood chord members and diagonal web members therebetween connected to the chord members by toothed metal plates. The diagonal web members under compression are wood having their ends fitted into notches in the chord members and the web members under tension are preferably metal with their ends connected to one side of the chord members by toothed plates which overlie the notches. The toothed plates connecting the ends of the compression members to the chord members overlie the notches on the other side of the chord members.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
A combination wood and metal truss structure comprising wood chord members and a series of diagonal compression and tension web members therebetween, said compression members being wood members oppositely inclined to said tension members, toothed metal plates connecting the ends of all said web members to the sides of said chord members, the opposed inner surfaces of said chord members having notches abuttingly receiving the ends of said compression web members, the connector plates for the compression web members overlying said notches on one side of said chord members, and the connector plates for the tension web members overlying said notches on the other side of said chord members, whereby movement of the compression web members laterally of said chord members is prevented.
Claim 2
Dependent Claim
123 words
A combination wood and metal truss structure comprising wood chord members and a series of diagonal compression and tension web members therebetween, said compression members being wood members oppositely inclined to said tension members, toothed metal plates connecting the ends of all said web members to the sides of said chord members, the opposed inner surfaces of said chord members having notches abuttingly receiving the ends of said compression web members, the connector plates for the compression web members overlying said notches on one side of said chord members, and the connector plates for the tension web members overlying said notches on the other side of said chord members, whereby movement of the compression web members laterally of said chord members is prevented.
Claim 3
Dependent Claim
29 words
A combination wood and metal truss structure as defined in claim 1, wherein the wood compression members and the notches are coextensive in width with said wood chord members.
Claim 4
Dependent Claim
25 words
A combination wood and metal truss structure as defined in claim 1, wherein the diagonal compression and tension web members alternate in a zig-zag arrangement.
Claim 5
Dependent Claim
72 words
A combination wood and metal truss structure as defined in claim 1, in which the tension members are metal and have load transfer flanges at their ends in abutment with said other side of said chord members, said flanges having a plurality of apertures therein and the toothed metal plates connecting said ends to said chord members overlie said transfer flanges and have their teeth extending through said apertures into the chords.
Claim 6
Dependent Claim
29 words
A combination wood and metal truss structure as defined in claim 4, wherein the wood compression members and the notches are coextensive in width with said wood chord members.
Claim 7
Dependent Claim
25 words
A combination wood and metal truss structure as defined in claim 4, wherein the diagonal compression and tension web members alternate in a zig-zag arrangement.
Claim 8
Dependent Claim
37 words
A combination wood and metal truss structure as defined in claim 4, wherein the toothed metal plates overlying the transfer flanges extend longitudinally of the chord members beyond said transfer flanges, said extended portions overlying said notches.
Claim 9
Dependent Claim
37 words
A combination wood and metal truss structure as defined in claim 6, wherein the toothed metal plates overlying the transfer flanges extend longitudinally of the chord members beyond said transfer flanges, said extended portions overlying said notches.
