  • Patent number: 4984489
    Abstract: An accessory for a hand drill which cooperates with the crank handle of the opening mechanism of a casement window. The accessory, when turned by the drill, facilitates turning of the crank handle and opening or closing of the window. The accessory includes a shaft which is intended to be gripped by the chuck or jaws of the hand drill in much the same manner that hand drills grip drill bits. A forwardly projecting crank handle-contacting head is provided which is adapted to slide over the crank handle. The head has a side opening with a pair of edges which push against one side of the crank handle in order to rotate the same. Preferably, the inside surface of the head of the accessory and the crank handle's contacting edges are rubber coated so that rotation of the accessory and its movement with respect to the crank handle will not mar the finish of the crank handle.

  • Patent number: 4979084
    Abstract: A device for supporting a decorative finial on a table lamp having a lampshade of the metal hoop-type. The lampshade is generally releasably secured to the lamp by a pair of opposed spring clips which slip over and grip the light bulb held in the socket of the lamp. The spring clips are connected by a pair of parallel wires to the circular hoop supporting the fabric of the lampshade. The device for the finial clips over the parallel wires of the spring clips and supports a finial on a less expensive hoop-type lampshade. This is in contrast to the more expensive harp and finial support provided on lampshades of higher quality lamps. The finial support comprises a plate member which is releasably secured to the parallel wires connecting between the spring clips and the circular top hoop of the lampshade. A pair of tabs releasably secure the device to the wire spokes of the lampshade.
