Abstract
An electromagnetic lock device includes a latch slidably received in a housing, and a follower rotatably secured in the housing and having an arm engaged with the latch and having one or more pegs. A spindle is slidably engaged in and actuated by the coil and coupled to either of the pegs by a link for rotating the follower in either of the directions to actuate the latch. The latch may be prevented from rotating relative to the housing. A casing is secured in the housing for receiving the coil. A spring may be used to bias the spindle toward the follower.

12. An electromagnetic lock device comprising:
-
a housing, a latch slidably received in said housing, a follower rotatably secured to said housing at a pivot pin, said follower including an arm extended therefrom and engaged with said latch for moving said latch inward and outward of said housing, said follower including a first peg extended therefrom, an electromagnetic member secured in said housing and including a coil, a spindle slidably engaged in and actuated by said coil, means for coupling said srindle to said first peg of said follower, said follower being rotated in a first direction to move said latch inward of said housing and being rotated in a reverse direction to move said latch outward of said housing, wherein said follower further includes a second peg extended therefrom, said coupling means couples said spindle to said second peg of said follower when said spindle is disengaged from said first peg, for allowing said follower to be rotated in said first direction to move said latch outward of said housing and to be rotated in the reverse direction to move said latch inward of said housing.
