Abstract: Hanging folder rods are flat strips having notches or hooks at their ends for riding on the rails of a file support frame. Notch depth is extended by long tips at the ends of the strip. By contouring the notches, extension, and end corners of the strips, the strips can be manufactured as a nested series with little void space between them. Strips nest, in one embodiment, with the top edge of one strip adjacent the bottom edge of another strip or, in another embodiment, with the bottom edges of two strips adjacent to each other. Manufacturing economy is effected by forming, for example, by stamping, the rods in the nested condition.

Abstract: A decorative expandable hanging file has closed reinforced sides, a supportive base and reinforced partitions. The partitions may contain vertically extending label surfaces to allow for file identification while the file is stored in a standard hanging file frame.

Abstract: A knockdown file cart which can be easily assembled without tools or fasteners, and which is rigid when assembled. The cart has two upstanding side panels with metal strips at their edges which form troughs. Two end panels have inwardly projecting flanges which can be slid down in the troughs and releasable locked in place by a spring tab on each flange that projects into a slot in the strips. A bottom panel can be inserted to form the bottom of the cart and further improve its rigidity.

Abstract: A convertible copy holder has tracks on its rear surface that allow it to be attached to a swing arm on a desk top brace as desired. Further, the holder is made hollow to provide a storage compartment. A rib is located along one edge of the copy holder to receive a line guide, which is structured so that it may be pivoted from the copy surface. Also, there is a channel along the top of the copy holder which receives, and slidably retains, a large paper clip.

Abstract: A spray booth (1) for use when spraying artwork is of pyramidal shape, and foldable for storage. An aerosol spray may be applied to the artwork via an aperture (6) at the apex of the pyramid which can then be closed by a flap (7) while the aerosol settles.

Abstract: A paper file folder has a repeating inked grid pattern. Each element of the pattern has printed lines surrounding an uninked background. The folder is used as an office product to provide decoration, a means for neat uniform labelling and a surface for optimal glue adhesion.

Abstract: Cutter apparatus is provided for sheet material, such as glass, plastic (e.g., plexiglass) or matte boards, particularly designed for use in picture framing, although also usable wherever such sheets need simple and reliable cutting apparatus. The cutter has means for holding a sheet of material in a position to be cut, a guide, and a cutter assembly or slide movable along said guide. The cutter assembly includes a movable cutter carrier resiliently urged toward said material. The cutter carrier holds two separate cutting elements, either one of which can be presented to the sheet material by pivoting the carrier. A lever moves the cutter carrier away from said material. A latch is provided for retaining the lever in a position with said cutter carrier retracted from said material, the latch being normally inoperative.

Abstract: A mat board cutter in which a cutter-carrying body has an end-to-end slot that affords adjustment by screws extending across the slot to bring bearing surfaces on the body into close-fitting relatively slideable engagement with a guide rail on which the body is slidably mounted.

Abstract: Sign-making materials are described which may be cut on a computer controlled sign cutting machine and then used to make subsurface signs, i.e. signs in which the legend is viewed through a transparent or translucent sign sheet. The sign-making material consists of a carrier with successively on it an adhesive layer, a film layer and a dye- or pigment-containing layer. The last of these adheres to the back of the sign sheet under heat and pressure. The first two may subsequently be removed, e.g. by using the adhesive to adhere the film layer to a sheet of material more strongly than the film layer is adhered to the dye- or pigment-containing layer, and then pulling the sheet of material away. The material enables the satisfactory production of very professional looking signs quickly and easily using standard computer controlled vinyl cutting machines, which are widely available in commerce, and a simple heated roller nip.

Abstract: A device for clamping and guiding a continuous sheet paper supply to a printer utilizes an inclined frame that supports pairs of rods. The paper from separate supplies passes between the rods. If not in use, the end of the paper is clamped at a convenient location with respect to the printer by the gravitational force of the upper roller on the inclined plane against the paper sheet and the lower roller. If the paper is connected to the printer, the rollers surrounding the paper may rotate to allow easy feeding to the printer.
