Abstract: A tape dispenser comprising a molded plastic frame having a base wall portion with a tape cutting edge and a pair of flexurable side wall arm portions extending in generally parallel side-by-side relation from the base wall portion and provided with C-shaped wall portions having opposed arcuate hub portions extending inwardly therefrom and adapted to support a tape roll. The hub portions are provided with axially engageable and releasable locking means adjacent the free ends of the C-shaped wall portions for firmly joining the hub portions together thereat simply by relative pivotal flexure movement of the arm portions to rigidify the dispenser.

Abstract: A stretchable thin plastic film and a double faces adhesive tape are mountable on exterior surfaces surrounding a building window or door to provide an external weather barrier. One side of the adhesive tape is adapted for mounting on a wide variety of external mounting surfaces at temperatures as low as 40.degree. F., and the plastic film is mountable on the adhesive on the other side of the tape at the same low temperature. The two adhesives have different adhesion strengths which enable the adhesive tape to be adhered to the mounting surface without separation therefrom during the stretching and adhering of the plastic film to the opposite side thereof and which adhesion strengths, with the film so stretched and adhered, provide for the film to be maintained against separation from the adhesive tape and the adhesive tape maintained against separation from the mounting surfaces under adverse weather conditions including gusting winds, rain and temperatures at least as low as 0.degree. F.

Abstract: A small, lightweight ornamental tape dispenser is adapted for hand held, desk top, or wall mounted use, and accomodates both right and left handed withdrawal of tape while remaining in a wall mounted position. A wall mounting means, a tape roll holding means, and a free standing base means are disposed at the rear side of an ornamental planar front wall member.

Abstract: An adjustable threshold assembly of simple construction and inexpensive to manufacture includes a bar member vertically adjustable in a channelway of a base member. A plurality of threshold height adjusting screws extend vertically downward through openings in a transverse bridge wall of the bar member and between and in self-tapped screw thread-like engagement with a pair of longitudinally extending opposed vertical walls of the bridge wall. The facing vertical sides of the opposed walls are advantageously formed with longitudinally extending extruded serrations of a cross-sectional shape approximately matching the cross-sectional shape of the screw threads of the adjusting screws to facilitate self-tapping of the adjusting screws into the opposed walls of the bar member.
