an alternative embodiment of the biased rotatable ring return mechanism the device being shown with the deadbolt in a semi projected position the rotatable ring 752 is constructed substantially around and in cooperating relation to the body 722 in the same way as described for the first preferred embodiment the rotatable ring 752 includes a radial finger 758 extending inward in contact with radial actuator 762 a return spring 750 is of the coiled extension type with end loops 742 744 as is known to those skilled in the art loop 742 of the return spring 750 is connected and held by a means around radial finger 758 the other loop 744 is held in place by slot 746 the coils of the return spring are held against and ride around a circular path on slide 748 by the tension of the return spring 750 the slide 748 may be an integral part of body 722 or can be an additional part made of plastic metal or any suitable material the slide 748 could be held rigidly or loosely within the body in a slot or by other means when rotating the rotatable ring 752 to project the bolt the radial finger 758 elongates return spring 750 with increasing tension until the bolt is projected upon release of the rotatable ring 752 the return spring 750 pulls the rotatable ring 752 around to the original position as in the other embodiments this embodiment can be reversed.
