Take out the sash stops, a thin vertical wood strip that holds the sash. Also, remove any paint-encrusted hardware. The sash should be pulled back to reveal the weight. It is a heavy iron or lead cylinder, which is tucked away in a cavity and is secured by a cord. To prevent the sash from falling into the void hit it with an hammer and then sacrifice the weight.
