I, EDWIN OTHO SACHS, of No. 11, Waterloo Place, Pall Mall, in the County
of London, Architect, do hereby declare the nature of this invention to be as
follows:
-
My invention relates to the construction of a stage floor in compartments which
can be raised above or sunk below the general level, as I shall describe referring
to the accompanying drawing which is a section shewing in section a compart-
ment of a stage floor according to my invention.
The floor A is supported by a trussed arch terminating at each side in vertical
legs L which run in guides, and have wire ropes attached to their lower ends.
Some of the ropes run over guide pulleys g g' and carry counterbalance weights G.
Others of the ropes C pass over pulleys g and under pulleys c to the barrel of a
winch 1) which can be worked by an electric or other motor E or by hand gear F.
Pits are provided for the legs L and the counterweights G.
As shewn in the drawing the floor compartment can be raised above the general
stage level as indicated at A¹ or lowered as indicated at A².
The floor sections are secured in any position into which they are moved by
means of any suitable locking gear, and the motion thereof may be controlled by
brake mechanism if necessary.
Dated this 21st day of December 1898.
