Abstract: The invention relates to a barrier apparatus for a framed vertically adjustable rectangular window, the apparatus having an adjustable length for insertion into a window casement of the window. It is slideably positionable within the casement. The barrier apparatus includes a first and a second gridwork panel horizontally spaced on co plan juxtaposition; the panels are rigid rectangular frames adapted to border and support the panels, each frame having horizontally disposed upper and lower borders, and inner and outer vertically oriented side borders, the inner side borders facing each other, the facing side borders having vertically spaced guide holes. Also provided are first and second horizontally directed posts affixed between the upper and lower horizontal borders of each panel, such posts affixed to the facing inner side borders and adapted to slideably penetrate the guide holes, the horizontally directed posts having uniformly spaced pairs of notches.

Abstract: A barrier apparatus for the safeguard of an open window, exhibiting first and second grid work panels horizontally spaced in slideable juxtaposition, the panels having rigid rectangular frames adapted to border and support the window, each frame comprising horizontally disposed upper and lower rods, an inner and outer vertically oriented border, the inner borders facing each other, such facing (inner borders) having vertically spaced guide holes, the inner and outer vertically oriented borders further having ornamental elements respectively secured at an offset horizontally transverse to the axis of the rods, which offset is approximately equal in extent to an outer transverse edge of a window casement, the plate metal means proportioned to respectively cover each of the first and second grid work panels, in which the sheet metal means will move with its respective panel as one panel is moved relative to the other.

Abstract: A barrier apparatus for the safeguarding of open windows. The apparatus exhibits an adjustable horizontal length adaptable for insertion into a window casement below a framed rectangular window, and slideably positionable within said casement. The barrier apparatus includes two mutually telescoping gridwork panels each constituting rigid rectangular frames adapted to define the panels. Additionally provided are vertically oriented seating posts affixed to upper and lower borders of the frames. Horizontally disposed upon each of the gridwork frames are posts having telescoping co-aligning series of holes such that the geometries thereof are suitable for their interlocking through the use of padlock.

Abstract: A device for attaching an identifying display to the antenna of a car in a parking lot has a threaded rod with a lengthwise channel that fits over the stem of the antenna, a lower nut that confines the stem in the channel, an upper threaded sleeve that fits over the enlarged tip of the antenna, and a screw that fits into the top of the sleeve. A ribbon or flag can be tied through a vertical slot in the top of the screw or a rigid display member can be threaded onto it.

Abstract: A safeguard system is provided to prevent unauthorized entry through an open window of a casement in which said window is vertically positionable. The system involves a barrier apparatus comprised of two framed gridwork panels in horizontally spaced coplanar juxtaposition. The spacing between the frames is adjusted by a coupling pin which insertively engages matching apertures in an extension arm and a horizontal border of a frame. A locking device is provided to prevent vertical movement of the window away from engagement with the barrier device.

Abstract: A safeguard system is provided to prevent unauthorized entry through an open window of a casement in which said window is vertically positionable. The system involves a barrier apparatus of adjustable horizontal size provided with posts that insert into channels in the window and the casement when the window is brought down against the barrier apparatus. A locking device is provided to prevent vertical movement of the window away from engagement with the barrier device.
