Hanger fastener

Claim 2

A slab hanger-fastener comprising: a frame plate, means for mounting the frame plate against a support surface, a guide member mounted on the frame plate for movement in a path extending between the ends of the frame plate, said guide member including means forming a rear channel on one side thereof which receives the frame plate and confines the guide member to movement in said path, a slab support member mounted on the guide member for movement in another path extending transversely of said first-mentioned path, said guide member having means forming a front channel on the opposite side of the guide member which receives the slab support member and confines the slab support member for movement in said other path, fastener means for securing together in fixed position said guide member and slab support member on said frame plate, said slab support member including slab positioning means on the front thereof for positioning slab edges, and a retainer member detachably mounted on the slab support member.

Claim 3

The slab hanger-fastener of claim 1 wherein said frame plate has a slot therein extending between the ends of the frame plate generally in the direction of said first-mentioned path, said slab support member has a slot therein extending generally in the direction of said other path, said guide member has a bore generally registering with the slots in said frame plate and said slab support member and said fastener means seats within said slots and said bore.

Claim 4

A mechanism for securing slabs to vertical surfaces: a generally elongate frame plate having front and back sides, said frame plate having an adjustment slot extending along its length, said adjustment slot having a countersunk margin on the back side of said frame plate, means for anchoring the frame plate to a vertical surface comprising fasteners extending through the frame plate at locations disposed beyond the ends of said slot, a guide member having means froming a rear channel on the back of the guide member, said guide member being mounted on the frame plate with said rear channel receiving the frame plate, said guide member further having means forming a front channel on the front of the guide member, extending generally normal to the rear channel, a slab support member mounted on said guide member received within the front channel, said slab support member having an elongate flange, which supports such slabs, generally paralleling said front channel, said flange including a post portion intermediate its ends, said post portion detachably receiving a slab retainer member which secures such slabs to said slab hanger-fastener, said guide member and frame plate being relatively movable in a path defined by said rear channel and the slab support member and guide being relatively movable in a path defined by said front channel, a bore in said guide member generally registering with said slot and another slot in said support member extending generally in the direction of said front channel registering with said bore, a fastener bolt having the head thereof seated within the countersunk margin of said first-mentioned slot and a shank extending through said first-mentioned slot, said bore and said second-mentioned slot, said shank terminating in a threaded end, and nut means screwed on said threaded of said shank serving releasably to secure the support member and guide member to said frame plate with different adjusted positions of said support member and guide member.

Claim 5

A mechanism for securing slabs to vertical surfaces: a generally elongate frame plate having front and back sides, said frame plate having an adjustment slot extending along its length, said adjustment slot having a countersunk margin on the back side of said frame plate, means for anchoring the frame plate to a vertical surface comprising fasteners extending through the frame plate at locations disposed beyond the ends of said slot, a guide member having means froming a rear channel on the back of the guide member, said guide member being mounted on the frame plate with said rear channel receiving the frame plate, said guide member further having means forming a front channel on the front of the guide member, extending generally normal to the rear channel, a slab support member mounted on said guide member received within the front channel, said slab support member having an elongate flange, which supports such slabs, generally paralleling said front channel, said flange including a post portion intermediate its ends, said post portion detachably receiving a slab retainer member which secures such slabs to said slab hanger-fastener, said guide member and frame plate being relatively movable in a path defined by said rear channel and the slab support member and guide being relatively movable in a path defined by said front channel, a bore in said guide member generally registering with said slot and another slot in said support member extending generally in the direction of said front channel registering with said bore, a fastener bolt having the head thereof seated within the countersunk margin of said first-mentioned slot and a shank extending through said first-mentioned slot, said bore and said second-mentioned slot, said shank terminating in a threaded end, and nut means screwed on said threaded of said shank serving releasably to secure the support member and guide member to said frame plate with different adjusted positions of said support member and guide member.

Claim 6

The mechanism of claim 3 wherein said support member includes two slots extending generally in the direction of said front channel, said slots being separated by a median web.
