Abstract: A dispensing device is provided for rolled sheet material. The device includes a base member and oppositely facing arms hinged to the base member. The arms are movable between an open position and a folded position wherein the arms completely nest within the base member to form a flush surface with the base member. A dual acting biasing mechanism is provided to bias the arm members away from the base member in their folded position and to bias the arm members towards the base member in their open position.

Abstract: Combined vehicle vent and escape hatch having a frame bounding a roof opening, a cover hingedly connected to opposite sides of the frame by hinge brackets for limited venting movement relative to one or more of the sides, one of the brackets being separable into cover and frame parts and normally prevented from separating by a cammable release rod engaging the cover part and a frame-backed movable stop plate backing the rod, and an emergency button instanding from the cover and when pushed operative to project the cover from all of said sides to full venting position and separate the parts of the separable bracket for enabling the cover, as an escape hatch, to be swung about the opposite bracket to open position. For extending the service life of the combined vent and hatch, an inner panel of the cover is backed by a rigid metal backup plate on which, for relieving the panel of stress, are hung the operating parts attached to the cover.

Abstract: A hingeless ventilator having a frame attachable to a wall of a compartment about an aperture therein, an opening in the frame alignable with the aperture, a closure member swingable against a side of the frame for opening and closing the opening, guide members fixed to and instanding from an opposite side of the frame beyond opposite ends of the opening, and a spring rod mounting on opposite ends composite rollers riding on the guide members and connected under tension to the closure member for selectively positioning the closure member relative to the frame, the roller assemblies each having an antifriction bushing journalled on the spring rod and in and bonded to an elastomeric collar engaging an adjoining guide member.

Abstract: Ventilator for roof or other wall of a vehicle in which an opening in the wall is normally closed by a closure member and the closure member is connected to the wall at each of a pair of opposite sides by a pair of spring-and-link assemblies enabling the closure member to be opened to any of five positions and yieldably held by spring force in closed and each open position. By mounting inside the spring-and-link assemblies a trim ring and coacting screen plate mounted respectively on the wall and the closure member, the ventilator is adapted to screen against entry of bugs or other foreign matter in all open positions of the closure member.

Abstract: A combined escape hatch and ventilator for a vehicle roof having a frame bounding its opening in the roof, a cover hingedly connected to the frame and normally limited in opening movement as a ventilator relative to one or more sides of the frame for ventilating an interior of the vehicle, one of the hinge connections being separable and formed of interfittable parts fixed respectively to the frame and cover and releasably connected by a latch pivotally mounted on one of the parts, the latch having a cam engageable with a lug on the other part for normally clamping the parts together and in an emergency enabling the parts of the separable connection to be disengaged and the cover swing about the connection on the opposite side of the frame for converting the roof opening to a fully openable escape hatch.
