  1. 1
    I claim:1. In a supporting bracket, the combination, of an arm, a supporting head, a stem 70 connected to said head and rotatably connected to said arm for rotation about an axis transverse to the plane of said head, said supporting head comprising a plurality of rigidly connected radiating arms having 75 flat article engaging surfaces, said stem projecting a short distance beyond the flat surfaces of said arm to facilitate centering of a board upon said head. .
  2. 2
    In a supporting bracket, the combina- 80 tion, of an arm, a. supporting head, a stem, connected to said head and rotatably connected to said arm for rotation about an axis transverse to the plane:of said- head, said supporting head, comprising a plural- 85 ity of rigidly connected radiating arms having flat article engaging surfaces, said:stem projecting a short distance beyond the. flat surfaces of said. arm. to facilitate , centering. . of a board upon said head, means for hold- 90 ing said stem against rotation with respect to said arm,, a clamp structure, and an. articulated connection, between the arm and clamp structure.
  3. 3
    In a supporting bracket, a clamp struc- 95 ture. comprising a pair of jaws having a portion of their facing surfaces cut-away and provided with centrally disposed longitudinally and transversely extending substantially semi-cylindrical cut-out portions, 100means for holding said jaws in clamping engagement with the support, said jaws, provided with recesses, in corresponding ends, an arm seated in said recesses and adjustably connected to said jaws, an article sup- 105 porting head, and an articulated connection between said head and said arm.
  4. 4
    In a supporting bracket, a clamp structure comprising a pair of jaws, means for holding said jaws, in clamping engagement 110 with a support, said j aws provided with recesses in corresponding erids, an arm seated in said recesses and provided with openings extending therethrough in angularly disposed sets, pins adapted to extend 115 through any set of said openings to adjustably connect said arm to said jaws, an article supporting head and an articulated connection between said head and arm.
