  • Patent number: 4827556
    Abstract: A ceiling fan blade cleaning device includes a fork member and a separable cleaner member. The fork member has a tubular handle by which the user holds the device for cleaning purposes and a pair of shafts extend from the distal end of the handle shaped to give the fork member a Y-shape. The cleaner member is formed of fibrous web material and has a rectangular central portion formed of a pair of spaced apart rectangular webs presenting an opening into which a ceiling fan blade may extend for simultaneous cleaning of its upper and lower surfaces. The side portions of the cleaner member have elongated channels into which the distal ends of the shafts extend to support the cleaner member on the fork member. Several embodiments of the devices are disclosed.

  • Patent number: 4719828
    Abstract: A screw starter device for temporarily holding a screw while starting it into a substrate is a truncated conical rigid tubular member that tapers downwardly from its proximal end portion to the distal end portion. A first arcuate concentric opening in its side is defined by a first proximal transverse edge, a first distal transverse edge and a first pair of longitudinal edges and there is a second arcuate concentric opening similar to, but smaller than and distal of the first opening. A first longitudinal slot through the side of the member extends from the first opening to the second and a second longitudinal slot smaller in width than the first extends from the second opening to the distal end of the member.

  • Patent number: 4691395
    Abstract: Waterbed frames for supporting and confining a bladder-type mattress having a head panel, a foot panel and a pair of side panels are improved to assist persons reclining in the bed to get out of the bed by providing at least one side panel with a section that can be lowered relative to the remainder of the panel creating an exit area along the side of the frame within which there is no obstruction against egress above the upper level of the mattress. To leave the bed, the person lowers the side panel section and passes through the resulting opened exit area.

  • Patent number: 4548449
    Abstract: A lamp socket attachment to convert a conventional screw-type light bulb socket into a spring insert type socket comprises a hollow cylindrical member open at both ends made of electrically non-conductive material divided by a transverse partition into upper and lower cup-like compartments, a cylindrical plug made of electrically non-conductive material is fixed concentrically in the lower compartment, there is a bore centrally through the plug and the partition, a contact member made of electrically conductive material slides captive in the bore, the contact member being adjustable in length, and there is a conductor member made of electrically conductive material having a lower portion extending along the outside of the plug through the partition and an upper portion extending along the inside surface of the upper compartment, such conductor member being structured so its lower portion will engage the threads of a screw-type bulb socket when the plug is inserted into the bulb socket and its upper portion wi
