Proudly displayed in our offices, Hamilton’s original 1925 kingpinless caster could just as easily roll on the factory floor today.
While kingpinless casters existed on the market back then, Hamilton’s founder, John Weigel, saw the need for a stronger, more durable version.
He patented “The Economic” 90 years ago, which featured an unconventional upper raceway for added vertical load handling. View the 1925 patent here.
Although it may have been the toughest kingpinless caster during the Roaring Twenties, that’s where the similarities end when compared to Hamilton’s current models.
Then vs. Now
A second raceway wasn’t The Economic’s only unique feature. One casting made up its upper portion (cup element) with the lower segment (wheel frame) comprised of another.
In comparison, our current models feature a much stronger forged-steel mounting plate and ring with heat-treated raceways for much longer wear.
