Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
142 words
A sky hook for supporting one end of a scaffold plank outside of a building window opening, comprising in combination a strong, rigid member formed with a hook at one end for hooking over a window ledge and a loop at its opposite end for said plank to fit therein, and a steadying cross brace across said member fitted with a bolt adjacent each end thereof for abutting against a building wall to securely space the rigid member from the wall, one of said bolts being located along said cross brace at a greater distance from said rigid member than the other bolt, such that a rotational threading of said one bolt causes less movement of said rigid member than rotational threading of said other bolt, whereby said one bolt provides for fine adjustment and said other bolt provide for course adjustment.
Claim 2
Dependent Claim
142 words
A sky hook for supporting one end of a scaffold plank outside of a building window opening, comprising in combination a strong, rigid member formed with a hook at one end for hooking over a window ledge and a loop at its opposite end for said plank to fit therein, and a steadying cross brace across said member fitted with a bolt adjacent each end thereof for abutting against a building wall to securely space the rigid member from the wall, one of said bolts being located along said cross brace at a greater distance from said rigid member than the other bolt, such that a rotational threading of said one bolt causes less movement of said rigid member than rotational threading of said other bolt, whereby said one bolt provides for fine adjustment and said other bolt provide for course adjustment.
Claim 3
Dependent Claim
90 words
A sky hook as in claim 1, and comprising rivet means for coupling said cross brace to said rigid member, and aligned openings in said cross brace and said rigid member for receiving said rivets, said openings being larger than said rivets to permit a loose fit of the rivets in the openings, and the rivets being of sufficient length to permit slight rotational movement of the cross brace with respect to the rigid member, to accommodate irregularities in the building wall surface against which the sky hook is installed.
