Stage Screws
Because of their shape, these pieces are sometimes offered for sale as corkscrews. They
are actually stage screws.
The stage screw design above left was offered in a c.1950 catalog from H. M. Sanders
Co., Boston. Red, white, and blue finishes were available at prices ranging from $12.35
to $13.80 per dozen.
Definition: STAGE SCREW A large screw which is screwed through the
foot
of a
stage brace to secure it to a strong wooden floor. Only suitable for use in theatres with
non-precious wooden floors!
Frank Lippincott wrote
In utilizing my
invention the screw may be inserted in the
stage-floor, walls, or upper structure to
provide a fixed point of attachment, so that
cables, hooks, guy-ropes, &c., may be readily
engaged with the ring portions and fastened
to the handle, or the device may be used in
connection with the various stage-settings
and scenery-frames as a fastening means or
coupling member.
