Pl.  XXVIII.    Hinged  Shelf  Support. 
This  bracket  admits  of  the  shelf  being  raised  or  lowered  at  will,  thus  securing 
such  angle  as  may  be  desired.  For  certain  installations  the  bracket  is  made  with 
a  plate  on  the  back  for  screws;  it  is  then  fastened  directly  to  the  wall  or  screen, 
thereby  avoiding  the  use  of  wall  plate.  A  narrow  strip  placed  on  the  top  and 
parallel  with  the  bracket  secures  one  end  of  the  material. 
Detail  of  Case  Frame  Top. 
This  case  is  designed  with  a  view  to  giving  a  maximum  side  light  without  a 
center  support,  and  a  self-sustaining  top.  The  metal  bar  shown  in  plate  runs  all 
the  way  around  and  across  the  center,  the  whole  being  bolted  together.  In  large 
cases  the  bar  is  of  wrought  iron  one-half  inch  thick  and  four  inches  wide. 
Vertical  Screen. 
This  screen  forms  either  a  central  partition  or  a  back  to  a  case.  The  objects 
are  placed  on  the  face.  The  interior  frame  is  made  of  %-inch  material  and  both 
sides  are  sheeted  with  J^-inch  pine;  over  this  is  stretched  a  cover  of  sign-writer's 
muslin  upon  which  an  ebony  finish  is  placed.  Its  adaptability  and  convenience 
are  unquestioned.
