Some Atlas 42 vintage drill press help

[289kman]

Hi, All...
So I bought a Atlas 42 drill press at a garage sale.
Love it
First time using it...put the drill bit in I wanted and tightened down the keyless chuck..(?).
Next job...looking to remove the bit and put in a bigger bit...and for the life of me, I can figure out how it loosens???
Any one used this type before?

So...none of the garage wizards here can tell me how to loosen this chuck or what tool I need to do so?

It's just a keyless chuck. And it didn't come with that drill press.
Grab and twist.

Use a rubber strap wrench to grip the chuck. Hold the spindle pulley still with your other hand.

Excellent idea!
Thanks Whitworth!
