Abstract: A towel roll holder and towel dispenser includes a housing for retaining a roll of toweling. The housing is affixed to a support surface, and easily opened or removed for replacement of the roll. In one embodiment, Velcro strips mounted on the support surface releasably engage oppositely configured Velcro strips mounted on an outwardly extending flange on the base of the housing. In another embodiment, magnetic strips or ferromagnetic material mounted on the support surface releasably attach to complementary strips on the housing flanges. In another embodiment, one side or end of the housing base flange is hinged to the support surface, and the opposite side or end of the housing base flange is releasably attached to the support surface with Velcro or magnetic (or ferromagnetic) strips as referred to above, or a rotatable latch. Towels may be dispensed from a narrow end of a cone-shaped nozzle on the end of the housing, or through a slot in a housing wall.

Abstract: An extended-life trash receptacle includes walls forming a body having an open bottom. A replaceable bottom is adapted to fit within the body. The walls include flanges or other support means on their lower peripheries for supporting the replaceable bottom, and retaining strips or other retaining means for holding the replaceable bottom on the support means. The replaceable bottom is preferably made of plastic, Fiberglas, hard robber, aluminum, or other suitable strong, durable, tough, non-rusting, non-corroding, and relatively chemical-impervious material. If the replaceable bottom becomes worn, punctured, or otherwise damaged in use, it can be quickly and easily replaced by removing the retaining means and lifting the bottom out of the body. A new replaceable bottom can then be dropped into place in the body, and the retaining means reinstalled. The trash receptacle can then be returned to service, thus extending its useful life.

Abstract: A plastic-sandwiched framework structure for constucting a portable folding table. The structure includes upper and lower plastic table top halves and a framework grid sandwiched therebetween. The table top halves are bonded or cemented to one another. The framework grid is preferably made of wood, and includes joists or beam members interconnected by cross members. The framework grid is received in a correlatively shaped shell integrally formed in the lower half of the table top. Folding legs are mounted on the underside of the table top and connected through the lower table top half to the cross members. The lower table top half is provided with gussets at selected locations between relatively high vertical walls and the adjacent horizontal planar surfaces. Substantially all other interfaces between vertical and horizontal surfaces on the exterior of the lower table top half are provided with a radius. Stiffening ribs, which may be extensions of the shell, are also disposed on the lower table top half.

Abstract: The method disclosed includes positioning a furnace disposed within a shelter outside near the building, the shelter has an inlet for receiving ambient air and an outlet for passing air heated by the furnace out of the shelter. An air duct is mounted between the shelter and an opening into the building. A solid fuel is burned within the furnace to heat the air within the shelter and the heated air is transported through the duct into the building to provide supplemental heat in the event the supply of fluid fuel is interrupted.The apparatus disclosed includes a shelter having walls with an inlet for receiving ambient air and an outlet for passing heated air out of the shelter. A furnace is disposed within the shelter for heating the air and includes a grate for supporting solid fuel to be burned and an exhaust stack extending through the walls of the shelter for carrying exhaust gases from the furnace without mixing with the air within the shelter.
