Abstract

A method of making a furniture leveling device and product wherein a metal blank is stamped to provide at least a pair of openings which upon further shaping of the blank into a C-shape become aligned, one of the openings having a portion of the blank extruded thereabout to provide a depending metal throat having at least three threads for supporting a bolt, the bolt being adjustable through an opening in the furniture piece for convenient leveling.

Claims

1. A method of fabricating a leveling device for a furniture piece comprising stamping a first opening in a generally rectangular metal blank to provide a bore of predetermined diameter, stamping a second opening in said blank to provide a bore in diameter less than said predetermined diameter while extruding said blank thereabout to provide a depending metal throat, threading said second opening to provide at least three threads, shaping said metal blank into a generally C-shape to provide spaced arms containing said openings in aligned relation and installing a threaded bolt in said openings.

2. The method of claim 1 in which said C-shape has a straight part connecting said arms, and shaping said straight part with a rib extending between said arms.

3. The method of claim 2 in which said blank is shaped with gusset means between said arms and said straight part.
