Abstract: A precipitation resistant ventilator for a structure enclosing an interior space. The ventilator encloses a space that is in communication with the structure interior space. A thin sheet of air permeable water resistant material is disposed within the ventilator interior. The thin sheet of air permeable water resistant material forms a barrier that excludes the entry of precipitation and other foreign matter into the roof structure while still allowing air exchange.

Abstract: A rolled ridge vent comprising a longitudinal blank of corrugated plastic sheet material having an undivided top panel extending its length, and segmented portions extending laterally from each side of the top panel scored to be folded into opposing pairs of vent parts. Adjacent segmented portions may be cut entirely through or perforated for manual separation. The entire blank is spiral rolled in the longitudinal direction. The ridge vent is installed by placing the roll on the peak of the roof with the free end extending over the top and oriented away from the direction of installation. The blank is unrolled to expose at least one pair of segmented portions, which are then folded under the top panel to form the vent parts and fastened to the roof. This process is repeated until the desired length is installed. Foam end caps and air deflectors optionally may be installed.

Abstract: A ridge peak roof ventilator comprising a pair of vent parts disposed on opposing sides of an opening in a roof peak, and a top panel disposed above and connecting each of the vent parts. The vent parts may be of unitary construction, folded from interconnected panels, or assembled from individual layers of sheet material, and each forms a multiplicity of air passages through which air flows from the interior to the exterior of the roof ventilator. The top panel is constructed from double-faced corrugated plastic having a pair of planar plies and a convoluted intermediate ply. The underside of the top panel is routed along the centerline to form a concave recessed area, thereby cutting away a section of one planar ply and part of the intermediate ply to form oval-shaped openings. Each opening has side walls traversing concave arcuate paths between a maximum height adjacent the side edges of the recessed area and a minimum height along the centerline.

Abstract: A ridge cap type roof ventilator comprising a plurality of sections aligned longitudinally with one another and hingedly interconnected along their confronting ends such that the plurality of sections may be folded or pivoted into parallel abutting contact. Once folded, several roof ventilators may be stacked with their vent parts in an overlapping, interfitted pattern to provide a stable column or stack having a minimal volume to conserve the space required to store or ship a predetermined number of the roof ventilators. The sections may be unfolded for positioning and installation on the ridge of the roof.

Abstract: A cabinet is disclosed which includes a frame defining a cabinet interior. A plurality of dividers separate the cabinet interior into a plurality of storage compartments. The frame includes opposing side walls and top and bottom walls. The top wall is attached to the side walls by first and second mounting plates carried on the side walls and top wall, respectively. The first plate is resiliently urged against the side wall. The second plate is sized to be received between the first plate and the side wall, with latch mechanisms for holding the attaching plates in position.

Abstract: This invention relates to an attachment for a fork lift. The attachment permits the fork lift to handle and invert a cylindrical drum of predetermined dimensions. The attachment includes a frame carrying pivot arms which pivot between first and second positions. Distal ends of the pivot arms carry rotating clamps which grip a drum and invert the drum. A clamp motion control mechanism is provided for selectively rotating the clamps and includes a dual piston pressure actuated cylinder. An over-center locking mechanism is provided for locking the pivot arms in a gripping position.

Abstract: A portable, open top utility tote container constructed and shaped from a lightweight yet durable, semirigid, corrugated plastic material used to store or transport an unlimited variety of household or industrial items. The receptacle portion of the container is formed from a single sheet of material, cut, scored into panels, and folded to the shape of a tapered rectangular box. End panels and side flaps are folded over a reinforcing rim which runs around the top perimeter of the container, the end panels being cut out to form hand grips at opposing ends of the container, and the side flaps creating a firm stacking shoulder upon which the container may rest when stacked on other similar containers. The single sheet of material from which the receptable is formed, when extended in a single plane, has a configuration confined by a rectangle whose length and width are the distances between the outer edges of the end panels and side flaps.

Abstract: A stand is designed for holding a computer printer and in particular mounts the printer at right angles to conventional practice so that the platen of the printer runs front to back on the stand rather than side to side. Such an arrangement allows easier access to the printer. The stand is provided with a shelf below the top surface for storage of paper which is to be printed, and provision is made for a slot in one or both side walls to feed the paper upwardly and outwardly into the printer. Each of the two side walls is generally planar and imperforate with the exception of the slots for the aforementioned paper feed. A basket may also be provided for reception of the paper after printing.
