Abstract:

A window noise attenuation device that keeps window balance springs from ratting against the inside of the spring covers when the balance spring is caused to vibrate. The apparatus is designed to be slipped over the window balance spring during the construction of the window. The device can be installed either by hand or by machine. The apparatus features a positioning section that keeps the device substantially fixed in position on the balance spring during use. An offset section holds the balance spring fimly in position away from the walls of the spring cover and jamb liners when the balance spring is caused to vibrate by rapidly closing or opening the window or from other jarring such as slamming a door. The low cost device is designed to last as long as the window spring mechanism.
