Plans - for a wooden lock

[Harlequin]

can any of you direct me to a site for plans on making a wooden latch type lock.
The one I remember had a central wheel mechanism on turning which bars (of wood) would extend out radially to latch the door and the reverse to unlock.
Can't remember what this type is called
Really appreciate your help
