Ajax Hand Brake Co.
One of the most widely utilized vertical brake wheels was the
Ajax 3059 (5) introduced in 1929. With only minor changes, the
model 3059 wheel was applied to new cars until the early 1950s,
when Ajax replaced the cast malleable iron wheel with a pressed
steel wheel with eight spokes and a large scalloped hub (6).
