US Patent:

8060984, Nov 22, 2011
Filed:

Feb 25, 2009
Appl. No.:

12/392616
Inventors:

Curtis Levermore - Fairport NY, US
Douglas Zinter - Rochester NY, US
Assignee:

Caldwell Manufacturing Company North America LLC - Rochester NY
International Classification:

E05D 13/00
US Classification:

16197, 49445
Abstract:

The present device is an extender for pretension spiral rod window balances. The spiral rod extender is attached to the end of the spiral rod by the window or balance manufacturer. At the window manufacturer, the sash is installed into the window frame and the balance is inserted into one of the jamb channels. A hook tool, having a hooking element at one end, is used to grab onto a hole in the end of the spiral rod to pull it a sufficient amount out of the containment tube. The hook tool manipulates the spiral rod so that a sash hook mounted on the balance engages a ledge at the end of the sash, thereby securing the balance to the sash. The spiral rod extender is then removed from the spiral rod and may be reused by the balance manufacturer or discarded as desired.

US Patent:

20080086840, Apr 17, 2008
Filed:

Jul 26, 2007
Appl. No.:

11/828527
Inventors:

Richard deNormand - Victor NY, US
Wilbur Kellum - Hilton NY, US
Douglas Zinter - Rochester NY, US
Assignee:

CALDWELL MANUFACTURING CO. - Rochester NY
International Classification:

E05D 13/00
US Classification:

016193000
Abstract:

This hanger system for use in window balances features a hanger connected at a lower end of a window balance. The hanger has a carrier interface for connection to the window sash carrier. The carrier has a hanger interface for connection to the hanger. The interfaces are connected and disconnected by a pivoting motion of the hanger with respect to the carrier. Once connected these elements cannot be pulled apart and disconnected by tensile forces without first reversing the assembly steps. A snap connection may also be advantageously added to the hanger and carrier, allowing them to snap together in permanent or non-permanent fashion when fully or partially pivoted into alignment with each other.

Filed:

Mar 17, 2008
Appl. No.:

12/049536
Inventors:

Tobias Peter Dallas - Rochester NY, US
Wilbur James Kellum - Hilton NY, US
Douglas E. Zinter - Rochester NY, US
Richard S. deNormand - Victor NY, US
Assignee:

Caldwell Manufacturing Company - Rochester NY
International Classification:

E05D 15/22
E06B 3/00
US Classification:

49181, 49506
Abstract:

A carrier and balance assembly for installation into the jamb channel of a window frame. The carrier and balance assembly are capable of being installed into the jamb channel optionally either as a single assembly or as two separate components. The two separate components are the carrier and a hanger-balance subassembly. The advantage of installing the carrier and balance assembly as two separate components is that such installation can occur after the assembly of the window frame and even after installation of the window into the wall of a building. Once the carrier and hanger-balance subassembly are separately installed in the jamb channel, they are then non-permanently locked together. Should any part of the carrier and balance assembly become damaged, replacement is performed by simply reversing the process described above without having to damage the jamb channel.
