  • Patent number: 6443702
    Abstract: A motorized ceiling fan lifting and lowering apparatus for lowering a ceiling fan so that the ceiling fan may be easily cleaned. The motorized ceiling fan lifting and lowering apparatus includes a tubular member, which is elongated and has a first end and a second end. The first end is open. A shoulder is integrally coupled to an edge of the first end and extends inwardly. A lip extends upwardly from the shoulder. The lip has a threaded inner surface. The second end of the tubular member is coupled to a ceiling fan. A motor is attached to the ceiling. A shaft has a first end attached to the motor such that the motor may selectively rotate the shaft in a first direction or a second direction. The shaft is threaded and has a second end extending through the lip and into the tubular member such that the shaft threadably engages the lip. An actuator selectively actuates the motor in the first or second direction for lowering and lifting the ceiling fan. The actuator is electrically coupled to the motor.

  • Patent number: 6073892
    Abstract: A modular projector lift system for moving a projection device along a path between an extended position and a retracted position. The modular projector lift system includes a drive assembly expandable along a first axis. At least one movable support is mechanically engagable with the drive assembly at a plurality of positions along the first axis. The movable support moves the projection device between the extended position and the retracted position. A brake mechanism is optionally included for retaining the projection device at a particular location. The brake mechanism includes a plurality of rotating brake plates connected to the drive shaft of the drive assembly and a plurality of static brake plates connected to the drive assembly compressively engaged with the rotating brake plates. Adjustable limit switches are optionally provided for adjusting a location of the retracted and the extended positions along the path.

  • Patent number: 5779216
    Abstract: An improved power tool torque and weight balancing apparatus for use in in-line assembly processes that require power tools, such as in the assembly of automotive engines. The power tool and weight balancing apparatus consists of a pivoting mounting frame, either suspended from a rail or fixedly mounted on a four-roller trolley, attached to a balancer frame that holds an air or spring powered balancer mechanism. The balancer mechanism has a cable with a swivel connector attachment which travels inside a set of telescoping tube members and attaches to a mechanism for holding a power tool. The mechanism for holding a power tool may hold a horizontally or vertically mounted power tool and is pivotable 360 degrees for operator convenience.

  • Patent number: 5772169
    Abstract: An acoustic ceiling compression strut system and method to help a suspended office building ceiling withstand an earthquake. The system includes two elongated tubes in a telescoping relationship and an adjustable locking connector placed between the two tubes and having a U-shape with two legs and a base. One tube is placed to abut a deck of the office building while the connector abuts the bottom of the tube. Thereafter, the second tube is lowered to abut a grid and the legs are bent around the top of the second tube thereby locking the two tubes and the connector and causing them to become a rigid strut.

  • Patent number: 5568954
    Abstract: A device for holding a door upright for painting comprises a bracket that attaches the device to the electrical junction box in a ceiling, a telescoping rigid section held by the bracket, and a pin at the end of the rigid section that engages the top edge of the door. The telescoping rigid section adjusts to different door sizes and different ceiling heights. It also moves to a retracted position from an extended position, so that the door can be easily positioned and removed. In the vertical position, only slight force is needed to hold the door there, force provided in part by the attachment of the device to the junction box. Use of the junction box obviates the need for more elaborate support systems.

  • Patent number: 5382042
    Abstract: A towing device support is disclosed. The invention features a telescoping assembly having an inner telescoping member slidably disposed within an outer telescoping member. The invention further comprises a latching arm which, in cooperation with a plurality of dimples formed upon an outer surface of the inner telescoping member, restricts the sliding movement of the outer telescoping member relative to the inner telescoping member in at least one direction. When a towing device, fitted with the invention, is lifted, the telescoping assembly contracts. When the lifting motion is stopped, the invention suspends the towing device in the air, facilitating alignment and hitching by one person.

  • Patent number: 5315784
    Abstract: A device for rotating a hanging plant to keep it from growing lopsided. The device has counteracting coaxial tension springs of opposite hand that rotate the plant first in one direction when the plant is watered and then in the opposite direction as the plant goes from wet to dry. A weight change of 10-20% is sufficient to rotate the plant at least 1/2 turn. An indicator is responsive to changes in the length of the springs as the plant dries out and as the springs are axially unloaded.
