My invention relates to an improved bracket clamp or stay for the purpose ot' putting up stagings on shingled roofs; and it conjecting' spur, C, which assumes, whenthe arm B is thrown up, a position in the recess a of the upper clasp end, and which enters or bites into the top part ot' the shingle when the supporting-arm B is thrown down to rest with its outer angular part on the butt ofthe next Course of shingles.
Thebent-up outer end ot' arm B forms the support or stay for the staging, which is, by the use ot' a number of brackets, strongly and securely supported, while admitting the ready putting up and taking oft' ofthe staging.
When the supporting-arm is swung up the spur releases the shingle, and the bracketstay may be readily slipped out, saving thereby time and expense in erecting the staging, and dispensing with thenailing through or otherwise injuring the roof.
llaving thus described my invention, I
cla-ini as n ewan'd desire to secure by Letters Patent- A' springclamp, A, combined with a-pivoted spur-arm, B C, having rear angle-arm, to
