Abstract
Abstract A truss spacer and support device for installation between the chords of adjacent trusses includes an elongate, generally U-shaped channel member. There is a tongue on each end having at least one nail integrally formed thereon which is adapted to overlie the top of a chord with the integral nail embedded therein. Tabs extend from each side of the channel member at each end with at least one nail integrally formed thereon. The tabs are raked inwardly toward the opposite end sufficiently that the ends of the nails do not extend past the ends of the channel member sufficiently to interfere with positioning the device between the chord members of adjacent trusses. The tabs can be bent to overlie the sides of the chord, with their integral nails embedded therein. The devices are employed to accurately space and support trusses during construction of a structure, and to provide added support against in-service loads.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
119 words
A truss spacer and support device for installation between chords of adjacent trusses, the device comprising: an elongate channel member having first and second ends and a tongue extending from each end with at least one integrally formed nail thereon, the tongue adapted to overlie the top of a chord with the integral nail embedded therein; and tabs extended from each side of the channel member at each end with a nail formed integrally thereon, the tabs raked inwardly toward the opposite end sufficiently that the ends of the nails do not extend past the ends of the channel member, the tabs adapted to be bent to overlie the sides of the chord with their integral nails embedded therein.
Claim 2
Dependent Claim
119 words
A truss spacer and support device for installation between chords of adjacent trusses, the device comprising: an elongate channel member having first and second ends and a tongue extending from each end with at least one integrally formed nail thereon, the tongue adapted to overlie the top of a chord with the integral nail embedded therein; and tabs extended from each side of the channel member at each end with a nail formed integrally thereon, the tabs raked inwardly toward the opposite end sufficiently that the ends of the nails do not extend past the ends of the channel member, the tabs adapted to be bent to overlie the sides of the chord with their integral nails embedded therein.
