These pieces should have eyes screwed in the backs for engaging hooked
rods which are united to the stage and act as supports. One illustration
shows the simple form of these braces, the other shows in working detail
a patented extending brace which is designed to deal with any piece of
scenery that may come to hand, for by loosening the thumb-screws at the
joint the brace can be shortened or lengthened to enable the hooked top
to catch in the fixed eye on the flat, etc., at any angle.
