Suspended ceiling system

A suspended ceiling system comprising main members extending parallel to each other and cross members extending between the main members at spaced intervals, each of said members having an inverted tee configuration with a pair of oppositely extending flanges connected by a web portion to a bead, each cross member having ends with an end surface of the bead extending beyond end surfaces of the flanges by an amount slightly less than the width of a single flange and the web portion having a tongue extending beyond both the end surfaces of the bead and flanges, each of the webs of the main members having elongated slots for receiving the tongue of the cross member with the end surface of the bead contacting the bead of the main member as the end surfaces of the flange of the cross member engage an outer edge of the flange of the main member, each of the tongues having first means cooperating with the elongated slot to lock the tongue in the slot and second means cooperating with second means of another tongue to interconnect the two tongues together to form an end-to-end joint between cross members extending into the elongated slot from opposite directions, said first means including a pair of tabs forming a pair of catch surfaces facing away from the end of the tongue, said tabs being spaced apart by an elongated aperture extending parallel to the bead and being positioned in the tongue with a portion extending on each side of the web of the main member to provide apertures for receiving clip means for positively locking the cross member to the main member.
