Time locks

A time lock having a housing, a clockwork mechanism mounted in said housing, a carrier assembly movably mounted in said housing, timed release means associated with said clockwork mechanism adapted to engage said carrier assembly at a preselected time to thereby move said carrier assembly, a snubber bar receiving aperture through said housing for receiving a snubber bar therethrough, snubber bar blocking means operatively engaging said carrier assembly and movable thereby when said carrier assembly is moved by said timed release means from a first position in blocking engagement in said aperture to a second position out of blocking engagement in said aperture, said snubber bar blocking means including an aperture in said carrier assembly, and an elongated lever extending through said aperture in said carrier assembly, said lever engaging a block slidably mounted in said housing for movement of the block to the first position into blocking engagement in said snubber bar receiving aperture, said block being urged downwardly to the second position out of blocking engagement in said snubber bar receiving aperture at one position of the lever and movable into blocking engagement therein by said lever at a second position of the lever, said carrier assembly aperture having abutment means thereon and said lever having abutment engaging means thereon adapted to selectively engage said abutment means whereby said lever is slidable through said carrier assembly aperture when said abutment engaging means is out of abutting engagement with said abutment means and held in a fixed relationship with respect to said carrier assembly when said abutment engaging means is in abutting engagement with said abutment means, said block being normally biased upwardly into blocking engagement in said snubber bar receiving aperture by a spring encircling a pin slidably mounted in said block when said lever occupies its second position, said pin terminating in a head portion at a point remote from said block and said snubber bar blocking means including a pivotal member having a first portion pivotally secured to said lever and a second portion underlying said head portion.

In a time lock having a housing having front and back walls, a clockwork mechanism mounted in said housing, a carrier assembly movably mounted in said housing for lateral movement in a vertical plane paralleling the back wall, timed release means associated with said clockwork mechanism adapted to engage said carrier assembly at a preselected time to thereby move said carrier assembly, a snubber bar receiving aperture through said housing for receiving a snubber bar therethrough, snubber bar blocking means operatively engaging said carrier assembly and movably thereby when said carrier assembly is moved by said timed release means from a first position in blocking engagement in said aperture to a second position out of blocking engagement in said aperture, said snubber bar blocking means including a block slidably mounted in said housing and movable to said first position into blocking engagement in said snubber bar receiving aperture and having an extension portion depending therefrom, a lever assembly including an elongated control member movable in a fore and aft direction generally perpendicular to the plane of movement of the carrier assembly between a forward release position and a rearward lock position and extending through said carrier assembly, said carrier assembly having an aperture therein for passage of said control member therethrough, said lever assembly including a pivoted member located rearwardly of the carrier assembly engaging said extension portion and movable between the lock and release positions regulated by said control member, said block being urged downwardly to said second position out of blocking engagement in said snubber bar receiving aperture at the forward release position of the control member and movable into blocking engagement therein by said pivoted member at said rearward lock position of the control member, said carrier assembly aperture having a formation defining abutment means thereon and said control member having abutment engaging means thereon adapted to selectively engage said abutment means whereby said control member is slidable forwardly through said carrier assembly aperture from said lock position to said release position when said abutment engaging means is out of abutting engagement with said abutment means and held at said rearward lock position in a fixed relationship with respect to said carrier assembly when said abutment engaging means is in abutting engagement with said abutment means.
