a conventional compound window or sash balance is shown in 90 u00b0 opposed views the combination of the spiral rod 10 and the torsion spring 14 are conventionally referred to as the u201c inner u201d sub assembly 1 it includes at least a spiral rod 10 having a first end 12 that extends from a first end 20 of the inner sub assembly 1 the spiral rod 10 is secured to a spiral shaped torsion spring 14 within the inner sub assembly 1 the torsion spring 14 may be either encapsulated by an optional containment tube 16 or it may remain non encapsulated fig1 a shows the sub assembly encapsulated by a containment tube 16 nonetheless whether a containment tube 16 is present or not an extension spring 18 encapsulates either the containment tube 16 if present or the torsion spring 14 see fig1 b to form a compound balance 2 in the present invention the direction of the turns applied to the torsion spring 14 and the extension spring 18 are preferably opposite each other in order to provide the balance manufacturer with the ability to cancel out opposing torsional forces acting on the spiral rod 10 the more these opposing forces are canceled out the less friction exists within the window system and the more lifting assistance is provided to the help the operator move the sash not shown either up or down in conventional compound balances there are no counter torque turns applied to the extension spring 18 to create an opposite torsional force that substantially cancels out the opposing torsional force of the torsion spring acting on the spiral rod 10 the first end 12 of the inner sub.
