(57) An electric lock of the swingable latch type, in that the latch (8) is biased by
a spring (10) into its door-opening position, but is held into its door-locking position
by the suitably shaped projecting portion (12) of an associated member (108) engaged
in means (113) at one end of, and integral with lever (13) fulcrumed about pivot (14)
parallel to pivot (6) pivotably supporting the latch (8), and biased by a spring (16)
in the proper direction for engagement of means (113) with the projecting portion
(12) of member (108), and into engagement through the stepped portion (19) formed
in its opposite end remote from latch (8) with the top end of a flat lever (20) of
ferromagnetic material, provided with lateral appendices (120-120') respectively extending
at right angles from the top and bottom end thereof, with their axis being parallel
to the pivots (14 and 6), and by which the lever (20) is swingably mounted in circular
seats (21-21') atthe upper and lower end of the wings of the support member (5), the
top end of lever (20) being swung into engagement with the stepped portion (19) of
lever (13) by the plungers (122-122') of solenoids (22-22') axially urged by springs
(24) toward lever (20), and being drawn out of engagement with the said stepped portion
(19) by the activation of solenoids (22-22'), resulting in the plungers (122-122')
being drawn into the interior of the respective solenoid (22-22'), whereby the latch
(8) is swung into its door-opening position.
