Abstract: A bookend for use with a bookshelf includes an upright, a base adapted for placement generally adjacent the bookshelf upper surface, a lower portion depending from the base, and an adjustable securement mechanism. The lower portion cooperates with the base to define a capture area, and the capture area is sized to receive the bookshelf front edge portion.

Abstract: An external steel grating has seven vertical bars welded at their ends to upper and lower horizontal hollow cross bars, end portions of which cross bars are bent rearwardly and secured to a building so that the grating overlies a window opening and protects it against illegal entry.One end of the grating has a loosely hinged connection with the building and the cross bars are jointed near the opposite end of the grating and locked in assembled relation by a hidden bolt in one of the cross bars. A cable from said bolt extends through the last mentioned cross bar to the interior of said building, which cable, when pulled, withdraws the bolt from its locking position and frees the joints for separation by gravity allowing the major hinged portion of the grating to swing freely outwardly and affording a ready escape from the building through said window.
