Knock-Down Footstool: Bolted Metal Legs and Rails Under a Screwed-On Wooden Top (Bolens, 1900)
Harry W. Bolens of Port Washington, Wisconsin, received US 640,265, dated 2 January 1900, for a footstool whose base comes apart: four metal corner legs and four rails bolted together, with a wooden top screwed on through lugs on the legs. It packs flat for storage and shipping.
His legs were ornamental castings; ours are bent from steel angle. All sizes are ours.

History and honest limits
**Harry W. Bolens** of Port Washington, Wisconsin, US 640,265, dated 2 January 1900, filed 4 October 1899. He claimed "a footstool-base consisting of legs provided at their upper ends with inwardly-extending flanges as well as horizontal lugs ... apertured for the engagement of top securing devices" and rails between the flanges. His legs and rails were castings, though he does not limit the material; the steel angle and flat bar, the bent lugs, the hardwood top and all sizes are ours.
