  • Patent number: 5623795
    Abstract: A draft insulator kit for use with an attic pull-down staircase comprises a dimensioned enclosure held together with plastic rivets and resting on weather stripping placed directly on the framing around the pull-down staircase. The edge of the box rests on the weather stripping to seal against drafts. The insulator can be covered with fiberglass batting to increase R value but is itself a cost-effective seal against drafts. It can be folded for increased shipping efficiency, is made of low cost cardboard, and has low manufacturing costs. As a result, its payback time to the consumer is less than one season.

  • Patent number: 4612848
    Abstract: A compact, collapsible and automatically expansible mining canvas is constructed and arranged so that a mine worker may stand under a supported roof section and extend into a newly sumped coal portion a forward section of a mining canvas so as to direct the air flow across the face of a newly mined coal section so as to remove any dangerous gasses and debris escaping therefrom. The mining canvas comprises an upper support and a lower support connected by pivotal intermediate support members and a canvas which is connected there between and which is preferably pleated so as to allow collapsible and expansible operation. Included in this invention is the method by which a miner may stand under an already supported section and extend to within a few feet of the newly mined or sumped face a compact, collapsed but expansible canvas section that is easily transportable to the face and which upon expansion will engage the roof and floor of the mine so as to direct the air flow against the face.
