They are counterbalancers, allowing the window to be opened and closed without the use of electrical or mechanical devices. The sash-weights are typically disregarded or disabled by homeowners, and are turned into scrap when they fail. Consequently you may have to find replacements.

Sashes that were made later in the century utilized glue instead of pegs and can be separated by cutting through the glue line using an instrument, and then tapping the mortised part loose with a mallet.
