Abstract: A fastener body has a flat wall mounting surface with a recess in the body containing a fastener insert. The insert has a key for engaging a keyway in the adjacent portion of the fastener body, so that when the insert is only partially disposed in the recess the key and keyway engage each other to prevent relative rotation between the insert body and the fastener body. The fastener body also has a key receiving slot communicating with the keyway so that when the insert is disposed completely within the fastener body recess, i.e., after securing the insert and body to a wall, the fastener body may be rotated relative to the insert to orient said body at a desired angle. Thus, e.g., where the fastener body contains an article supporting hook, the fastener body may be rotated to straighten out the hook in the event that after hammering the fastener body and insert to a mounting wall, the hook is not vertical.

Abstract: A glass cutter having a cutting wheel rotatably mounted at one end thereof. A cutting fluid reservoir is situated within the tool housing at the end remote from the cutting wheel. The cutting wheel is mounted on a support member which is spring biased to provide a constant cutting pressure. A part of the wheel supporting member cooperates with the interior of the housing to form a valve which allows cutting fluid to flow through the wheel when the wheel is displaced against the action of the spring toward the housing during a cutting operation. A wheel cover pivotably mounted to the housing adjacent the cutting wheel has a closed position in which it protects the cutting wheel, and an open position in which the cover acts as a cutting guide.

Abstract: A method for making a fire retardant coil zipper is disclosed. The method involves using a fire retardant material bath exhaust process, that is, immersing the zipper in an aqueous bath of the fire retardant material and heating the bath under pressure to thereby impregnate the zipper with the fire retardant material while exhausting the bath.

Abstract: A bracket assembly has a rod with a hook, which may be a swivel hook, affixed to one end. A wall bracket is held on the other end of the rod, for maintaining any of a plurality of given angular displacements, in a horizontal plane, between the rod and a wall. The hook end of the rod is supported by a chain, cord or the like extending from a fitting on the wall above the wall bracket to a support point on the rod further from the wall than the hook. The wall bracket may have a pivot joint with a plurality of fixed pivot positions changeable only by lifting the rod, or it may be comprised of a block having a plurality of horizontal holes at determined angular displacements.

Abstract: A fastener adapted to be affixed to a hard wall, such as a concrete wall, has a base through which at least one hole extends. A bushing is releasably held in the hole at one end thereof, and extends outwardly, and a pointed pin is held in the center hole of the bushing. The bushing guides the pin into the wall, upon impact. The hole in the base and the bushing may be provided with flanges to inhibit their relative separation. A hinged cover may be provided on the base, to cover the bushings and pins when the fastener is affixed to a wall. In modification of the invention, the pin and bushing are replaced by a screw which extends into an expandable fastener in the wall. The expandable fastener may be formed as a unitary element with the base.

Abstract: A zipper has a pair of independently movable sliders, each of the sliders having a pull. The pulls have apertures through which U-shaped projections from the sliders extend, in order to loosely pivotally capture the pulls. The apertures of the pulls are elongated, so that the aperture may fit over the U-shaped projection of the other slider. Locking holes are provided extending through the U-shaped projections. The apertures of the pulls have unbroken edges, to maintain the strength of the pulls.

Abstract: A process for casting or molding a single internal thread at the same time that the desired product is cast or molded. The desired thread configuration is defined by two aligned and abutting identical core pins. Each of the pins has a protruding portion in the shape of a helical ramp extending through an angle of less than 360.degree.. The ramp has an outer diameter and pitch corresponding to the diameter and pitch of the desired internally threaded surface to be formed. The protruding portion of each core pin includes a vertically oriented surface extending between the ends of the ramp. A peripheral edge groove extending along the outer edge of the ramp defines the desired thread configuration. The aligned core pins are placed within a recess formed by mating portions of a die block to define the shape of the desired product.

Abstract: In a die casting technique, a first element is die cast with a cavity formed by a core, the first element having an interlocking surface such as a projection or shaped aperture. The core is then removed, and a second element is cast to extend into alignment with the cavity, employing the interlocking surface of the first element for a portion of the die in the formation of the second element. The second element is thereby interlocked with the first element to form a unitary article. The unitary article may be in the form of a hanger adaptable for use in extending a cord for suspending an object. The hanger has a body portion with a hole extending therethrough, one end of the hole being enlarged for receiving and holding therein the knot of a cord. A loop shaped portion of the hanger extends over the enlarged end of the hole. The loop shaped portion is rigidly affixed to the body portion, and serves as a hook.

Abstract: A carousel type unit for displaying consumer articles or products, said unit having a number of hexagonal plates rotatably mounted on a vertical support post. Each hexagonal plate has six display modules, one module being mounted to each of its six edges. The top edges of the modules mounted to each hexagonal plate are interlocked with the bottom edges of the modules mounted to the next higher plate. The modules are constructed so that a portion of the top edge of each module has a barbed configuration, and the bottom edge of each module has a corresponding bifurcated configuration, so that the top edge of any module can be interlocked with the bottom edge of any other module. Each module comprises an open enclosure with three co-planar retaining lips for allowing the above indicated products to be retained within the module while permitting the front surfaces to be exposed to view.

Abstract: A locking pulley assembly includes a pulley adapted to be affixed to a surface, a pull handle, a swivel hook, and a cord extending between the swivel hook and the handle around the pulley wheel. The pulley includes a unitary pulley wheel having locking grooves and coaxial frustoconical bearing surfaces, the pulley wheel being mounted for rotation in a unitary frame having inwardly facing frustoconical bearing surfaces engaging the bearing surfaces of the pulley wheel to form a rotatable joint. The handle is comprised of a cylindrical member having a central axial hole with reduced diameter at its central portion for holding a knotted end of the cord. The handle also has a slot at each end thereof of width slightly less than the diameter of the cord, to enable the handle to hold the cord. The swivel hook has a first element adapted to be affixed to the other end of the cord, and a hook pivotally mounted on the first member.

Abstract: A traveller for ring spinning and twisting is provided comprising a high modulus/low friction resin blended with a fibrous whisker material. A lubricant is usually added to the composition. The resulting traveller is characterized by a wear-life hitherto unavailable that is, a wear-life six to eight times greater than that of conventional travellers.
