Letters Patent No. 99,941, d ated February 15, 1.870'.
IMPROVEMENT IN SCAIFOLD BRACKETS.
The Schedule-referred to in these Letters Patent and making part of the same.
To all whom it may concern Be it known that I, EDWARD PARKER, of Plymouth, in the county ot'LitchIield, and State of Connecticut, han-'e invented :i new Improvement in Sca-t'- iold-Bracket-'for Shingling Roofs; and I do hereby de'clzne the following, when taken in connection with the accoinpznxying drawings and the letters of reference marked thereon, to be a full, clear, and exact description ot' the saine, and which said drawings constitute pa rt ot' `this specification, and represent, in-
Fignre 1, a perspective view; and, in
Figure 2, a side vicw to illustrate the object of the invention.
This invention relates to an' improvement in the construction of a bracket to support 'the scaflblding used upon roofs by joiners when shingling.
Heretot'ore the brackets have been formed of strips of wood nailed to the roof through the shingles. This nailing is more or less objectionable, frequently causing leakage in the roof-a diiculiry which is entirely overcome by my invention, which consists in the construction of a bracket `from twolegs jointed together at theirnxeeting ends, and provided with a. seginent, so that the angle may be changed,v and each leg vprovided'with a, forked end, so as to indent into the shinglesand sustain the bracket wherever placed.
A is one leg, here represented as the leg which supports the scaii'old.
B, the other leg, pivoted to the leg A at a, so as to be turned to different angles.
C is n segment, tixed to one of the legs-A,'nd adjustable on the other leg to the variation ofthe angle, and fixed by n set-screw, d.
'lhe leg A is forked or divided into two parts or braces, D D, each part toothed or pointed, so as to indent into the shingles, and the other leg divided into parts, E E, or constrmftedso 'as to indent into the shingles suiciently to'hold the foot of the brace.
v This completes the construction ofthe bracket. ltsoperation is as follows:
The liney EF, tig. 2, represents the lroofbeing shin'- gled. At the place where it is desired to 'platee the. seabld, tixA several brackets in line, the braces D of the leg being setY lirinly onto the roof :unltherangle adjusted,fthe other leg B also fixed onto the`root; then the,scaibld-boards laid onto the arm A in the usual lnanner'ot' plucing the sanne on the connnon bracket. t
It is necessary that one oi thelegs'be pnivided with n. double end as :ibraee to lhold the bracket in an upright position; and this muy be either one, but I prefer to divide the extreme end of both legs as shown.
I do not wish to be understood as broadly claiming root', as herein set forth.
EDWARD PARKER;
