Abstract: A gripping and fastening device comprising a bendable strip of material having integral slots is provided. The strip can have a formed hook or hanging shape for holding or hanging articles. The strip can be bent through at least one of the slots to grip the upper edge of a structure such as a wall partition or door, or other article. The integral slots allow for multiple repeated bending and unbending of the strip while preventing or delaying the material from work hardening through the bending area, and thus, fracturing. When straightened, the device retains its original shape. Preferably, there is no indication that bending has occurred. Preferably, the slots are rectangular shaped, but other slot shapes can be used, such as dog bone shaped slots.

Abstract: A bendable bookend having a first, non-operating position wherein the bendable bookend includes a substantially flat planar piece and a second, operating position wherein the bendable bookend includes a base and a support member extending upwardly from the base. In the non-operating position, the bendable bookend includes a base, a tongue extending from the base in a plane that is coplanar with a plane defined by the base, and a support member extending from the base in a plane that is coplanar with the plane defined by the base and in a direction toward the top end. In the operating position, the formed up bookend includes a base, a tongue, and an upstanding support member. The tongue extends from the base in a plane that is coplanar to a plane define by the base, and the support member extends upwardly from the base. Preferably, the bendable bookend includes a stiffening structure to help strengthen the formed up bookend.

Abstract: A combination clip and hanger is used to suspend articles from walls, especially fabric-covered soft-core partitions. In one embodiment, the clip-hanger is formed of a single strand of stiff but bendable wire. The wire defines three components of the hanger, namely, a clip, a hook, and a prong. The clip is formed by two or more segments of wire, oriented in a generally longitudinal direction, and located in approximately the same plane. The hook is a generally transverse loop of wire, connecting two of the clip-forming segments, and protruding from the plane of the clip. One or both of the free ends of the wire can be formed into a prong. In another embodiment, the wire is inserted through a generally flat backer. The backer tends to prevent injury due to the prong; it also tends to protect the fabric of the partition. When the clip-hanger of either embodiment is inserted into a fabric-covered partition, the prong separates the fibers of the fabric, generally without piercing the fibers.

Abstract: A hanging device facilitates the attachment of a foam board, or an equivalent object, to a wall. The hanging device has a body portion and at least one prong. The method of attaching the hanging device to the foam board includes the steps of inserting the prong upwardly into the foam board, and then rotating the body portion, which remains outside the foam board, so that at least part of the foam is compressed by the prong. If the foam board has a paper skin or backing, insertion of the prong creates a slot in the skin, and the slot tends to hold the device in position. The part of the body portion remaining outside the foam board can be suspended from a mounting device, such as a nail or a conventional picture hanger, affixed to a wall. The prong itself can also be bent towards the body portion, to increase the compression of the foam.

Abstract: A plastic bag is formed, filled, sealed and separated from continuous webs of plastic material. The webs pass downwardly between complementary U-shaped heat sealing jaws that reciprocate and cooperate to provide seams which form a pocket that is closed after it has been filled from above and indexed downwardly. The top seam of one pocket is formed simultaneously with the bottom seam of an adjacent pocket and a weakened line of juncture is provided therebetween. Grippers carried on the heat sealing jaws engage opposite sides of the plastic webs above the location of the top seam of the filled pocket and cooperate with a separator that tensions the webs along the weakened line to rupture the filled pocket from the webs while the webs are still in a thermally weakened condition.

Abstract: A hanger adapted to be driven into a wooden frame member includes a one-piece stamped metal member having a head and a flat elongate symmetrical shank with a series of lands and grooves disposed on opposite sides of the longitudinal axis of the shank between its tip and a pair of laterally extending shoulders on its head. Inclined camming surfaces extend between the lands and grooves and cooperate therewith to compress the wood fibers laterally of the shank as it is driven into the wood. A lateral gripping surface behind each land surface engages the wood fibers which expand into the distally adjacent groove to provide a positive gripping action which resists disengagement.

Abstract: A plastic bag is formed, filled, sealed and separated from a continuous web of longitudinally folded plastic material. The web passes downwardly between complementary L-shaped heat sealing jaws that reciprocate and cooperate to provide seams which form a pocket that is closed after it has been filled from above and indexed downwardly. The top seam of one pocket is formed simultaneously with the bottom seam of an adjacent pocket and a weakened line of juncture is provided therebetween. Grippers carried on the heat sealing jaws engage opposite sides of the plastic web above the location of the top seam of the filled pocket and cooperate with a separator that tensions the web along the weakened line to rupture the filled pocket from the web while the web is still in a thermally weakened condition.
