Patent number: 9038315Abstract: A mechanism is provided for balancing and positioning a sash of a self-balancing double-hung window assembly. The mechanism may include a fixed length cable, a pulley, first and second brackets and an adjustment member. The fixed length cable may include first and second ends. The pulley may support the cable. The first bracket may include one or more attachment points relative to the first end of the cable and may include an upper end and a lower end. The second bracket may be movable relative to the first bracket and may be configured to support the sash. The adjustment member may engage and extend through the lower end of the first bracket and may be movable relative to the first bracket to cause corresponding movement of the second bracket relative to the first end of the cable.Type: GrantFiled: October 4, 2012Date of Patent: May 26, 2015Assignee: Caldwell Manufacturing Company North America, LLCInventor: Wilbur James Kellum, III

Patent number: 9003710Abstract: A window balance assembly for installation in a window assembly can include a balance portion that is connected to a carrier that may have a first and second side. The balance portion may be arranged to be drawn out of the carrier on the first or second sides of the carrier. The balance portion may be a spring member or element. As the spring element is drawn out of the carrier, contact made between the spring element and the carrier may generate a friction that results in undesired chatter of the spring element and/or audible noise from the carrier. This friction may be reduced by controlling the contact made between the spring element and the carrier. Further, a reduction of friction between the spring element and the carrier may result in a reduction in spring chatter and a reduction in audible noise from the carrier.Type: GrantFiled: July 10, 2013Date of Patent: April 14, 2015Assignee: Caldwell Manufacturing Company North America, LLCInventors: Wilbur James Kellum, III, Jay Sofianek

Patent number: 8819896Abstract: A window balance assembly comprising an improved locking carrier mechanism is disclosed. The locking mechanism is actuated when the window sash is tilted. Cam surfaces on the receiver of the mechanism engage cam followers in the clamshell-type housing of the carrier forcing them apart outwardly to lock the carrier in the jamb channel of a window assembly and prevent movement of the carrier in the channel. The receiver incorporates two cams that engage two cam follower surfaces in the housing to improve the distribution of the locking forces of the carrier in the jamb channel. A dual-locking carrier expands in both the axial and lateral directions to contact both front and back surfaces and opposing side surfaces of the jamb channel.Type: GrantFiled: June 28, 2013Date of Patent: September 2, 2014Assignee: Caldwell Manufacturing Company North America, LLCInventors: Wilbur James Kellum, III, Eric Mertz, Mark R.

Patent number: 8448296Abstract: A carrier assembly can be used to couple a balance assembly with a window sash. The carrier assembly can engage the window sash to transfer a force from the balance assembly to balance a weight of the window sash. The carrier assembly, due to interactions of the window sash with the carrier assembly and the balance assembly with the carrier assembly, can tightly engage the window sash, either directly or through a bracket, to substantially eliminate unselected movement or forces applied from the balance assembly.Type: GrantFiled: October 14, 2011Date of Patent: May 28, 2013Assignee: Caldwell Manufacturing Company North America, LLCInventor: Wilbur James Kellum, III

Patent number: 8302258Abstract: A method and apparatus for reducing the torque of a compound balance in order to substantially cancel out the torsional force of the torsion spring acting on the spiral rod by creating an equal and opposing torsional force on the extension spring. The apparatus is an assembly connector that is non-permanently engaged with the extension spring, with the spiral rod being tensioned by the torsional force of the torsion spring. Alternatively, the extension spring may be turned in a direction to apply more torque than is required for operation of the compound balance. It is then engaged with a non pre-tensioned spiral rod sub-assembly to transfer the excess torque to the torsion spring of the spiral rod sub-assembly. In this manner, the opposing torsional forces of the torsion spring and the extension spring acting on the spiral rod substantially cancel out each other.Type: GrantFiled: April 2, 2012Date of Patent: November 6, 2012Assignee: Caldwell Manufacturing Company North America, LLCInventors: Robert M.
