Abstract: According to the present disclosure, a projector lift is provided to raise and lower a projector from the ceiling. The projector lift includes a first mount normally coupled to the ceiling, a second mount supporting the projector, a driver configured to raise and lower the second mount and projector, and a stabilizer extending between the first and second mounts.

Abstract: A mounting assembly including a housing for a roller operated system, such as a projection screen system, which facilitates installation in a building in stages to reduce the risk of damage to system components. The housing includes longitudinally extending lipped projections along its top wall. Attachment lugs of brackets that support the roller on which a sheet, such as a projection screen, is windable are adapted to engage the lipped projections and enable the brackets to be mounted to the housing at selected longitudinal locations to allow for positioning adjustments of the roller. The vertical side walls of the housing also are each constructed with a projecting lip adapted to engage an upstanding hook of the bottom closure panel to thereby enable the closure panel to be mounted to either of the side walls of the housing. A method of installing a roller operated system is also disclosed.

Abstract: A projection screen system is provided that is configured to mount to a structure. The projection screen system includes a housing, a roller, a screen, and a motor positioned to rotate the roller to raise and lower the screen. The projection screen system further includes a coupling configured to couple the motor to the electrical supply of the structure.

Abstract: An overhead projector mounting system is provided that is configured to support a projector in a ceiling of a room. The system includes a housing having an opening through which an image generated by the projector is transmitted. Preferably, the system includes a mirror to reflect the image generated by the projector toward a viewing surface in the room.

Abstract: A projection screen system that may be installed in a building in stages to reduce the risk of damage to the projection screen. The system includes a housing in which is mounted a socket circuitable with a power supply of the building. An assembly of the system that may be attached to the housing at a later stage of building construction includes a motor with a power cord, a roller and a projection screen. The motor rotates the roller to unwind the projection screen from around the roller and thereby lower the projection screen. A first end of the power cord is circuited to the motor, and a second end of the power conduit includes a plug that mates with the socket to operatively circuit the motor to the building's power supply. The housing also includes longitudinally extending lipped projections along its top wall.

Abstract: A casing for a projection screen system that includes a fascia removable from the spine of the casing without the use of tools. The casing is provided with a roll locking hinge formed by a cooperating lip and socket furnished on the fascia and the spine. The roll locking hinge is configured to permit the fascia to be preliminarily mated with the spine when the fascia is disposed in an upwardly rotated arrangement. After the preliminary mating of the fascia with the spine, when subsequently rotated downward relative to the spine, the fascia is locked to the spine by the roll locking hinge, thereby preventing inadvertent fascia removal.

Abstract: Wallpaper dispenser for automatically hydrating a film of glue pre-applied to one side of a roll of wallpaper. The dispenser includes a reservoir having a roll of wallpaper rotatably supported thereover and a roller for guiding the wallpaper within a quantity of water contained within the reservoir. A ramp is provided for cutting the wallpaper and includes a cutting ridge along which a cutting member is drawn to cut the wallpaper perpendicular to the length thereof. A tape measure and means for securing the tape measure adjacent the ridge are provided to indicate the point, forwardly of the ridge, adjacent which the forward margin of the wallpaper should be positioned. A slidable member is provided to automatically align the pattern on one strip of wallpaper with the same pattern on a previously cut strip when the strips are positioned in laterally adjacent relation and with the top margins thereof in alignment.
