  • Patent number: 4846919
    Abstract: Method of bonding a sole to a shoe by applying moisture-curable melt adhesive to the shoe upper, subjecting the adhesive coating to a hot-cure step with airborne moisture, and pressing the sole and shoe upper together with the adhesive between them immediately after the hot-cure step, preferably in less than 90 seconds after leaving the hot-cure. The bond is effected without application of adhesive to the sole, which is merely pre-treated by wiping with solvent or primer solution.

  • Patent number: 4836008
    Abstract: A solenoid actuated blind rivet tool having pulling impulse intensifying apparatus co-acting with the mandrel pulling mechanism. One type of impulse intensifying mechanism is a slidable connection of the tool's nose housing, housing the assembly for engaging and tensioning the mandrel, and power chamber which comprises the remainder of the tool housing, which power chamber carries a solenoid for powering the tool. The solenoid pulls the nose housing rearwardly until it impacts against the power chamber, creating a high-magnitude impulse force to break the mandrel. In lieu of a slidably mounted nose piece, the tool may include a member linked to the pulling mechanism and a ram which is driven against the member by the solenoid thereby creating an impulse force which is transmitted to the pulling mechanism.

  • Patent number: 4836730
    Abstract: A drilling and thread forming fastener is provided having a threaded shank and a pilot end. The fastener pilot end in cross section has a major and minor axis intersecting at the fastener center of rotation. A pair of arcuate flutes are disposed in opposed quadrants from a pair of arcuate lands, each of said arcuate flutes and an arcuate land intersecting on the major axis to form a cutting edge of the fastener, the two cutting edges being disposed in a plane containing the center of rotation of the fastener.The fastener construction is adaptable to applications in relatively thick materials including cement or cinder block, and is effective to increase tool life when manufactured by a forging process.

  • Patent number: 4836728
    Abstract: A blind rivet assembly with a tubular rivet body having a flange at one end and a mandrel which projects from the rivet flange and can be pulled to set the rivet at its tail end. The mandrel has heads at both ends, one to set the rivet and the other to engage pulling means of the setting tool. The setting and pulling heads of the mandrel are rounded. The mandrel has a neck within the rivet at which it breaks when the rivet has been set. The invention enables a shorter mandrel to be used, and facilitates its economical manufacture without adversely influencing the characteristics of the breakneck. The invention also facilitates feeding of the assemblies automatically to rivet setting tools.

  • Patent number: 4815636
    Abstract: Hot melt guns comprising a melt body having a melt chamber and a mechanism for feeding a rod of solid hot melt material to the chamber for melting and dispensing. The feeding mechanism comprises a carriage mounted for movement towards and away from the melt body, a clamp member pivotally mounted on the carriage and a trigger to cause the clamp member to grip the rod and feed it into the melt chamber. The clamp member has two pivot pins projecting from opposite sides, each pin having an arcuate coaxial bearing portion and at least one flat face. The pins are received in bearing openings defined by circular bearing surfaces in the carriage, Assembly openings are provided in each bearing surface extending around a minor arc and sufficiently wide for the pins to pass through when the flat faces are suitably oriented relative to the openings.

  • Patent number: 4814037
    Abstract: The invention presents to the art a novel, improved shoe stiffener which comprises co-extruded layers of plastics film. The shoe stiffener comprises co-extruded layers of plastics film, a first of the layers comprising an ionomeric material and providing a main body of the stiffener and a second layer comprising a plastics material which does not adhere to a fusion press under conditions normally encountered therein during bonding of a shoe stiffener to a shoe upper. Nylon 6 is the preferred second layer plastics material. The co-extrusion product replaces fabric backed shoe stiffeners in which flaws induced in the film by the fabric may provide notches from which cracks in the material can propagate.

  • Patent number: 4812095
    Abstract: A threaded fastener is provided having a head for accommodating a tool for rotating the fastener. A plurality of ribs culminating in teeth are provided under the head for engaging the material into which the fastener is inserted, each rib and tooth having a ramp surface and a brake surface, the ribs being oriented for inhibiting either clockwise rotation or counter-clockwise rotation of the fastener by torque created through contact of the brake surfaces with the material. The ribs are formed on the fastener during the heading process by means of a matched die set.

  • Patent number: 4797529
    Abstract: Control circuit for arc welding components to workpieces, in which a component is placed on to a workpiece by a weld gun and after a welding stroke is lifted from the workpiece in a return stroke by igniting a pre-current arc and is brought up to the workpiece again in a forward stroke during the burning of an interconnected welding arc, in which a sequencing control determines the tripping moments of return stroke and forward stroke as well as of the welding arc and a monitoring voltage is bypassed from the pre-current arc ignited at the welding point, characterized in that the monitoring voltage (V) is converted into a correction voltage (line 27) by means of a set-point comparator (25) and is superposed on a control voltage (line 18) for principally controlling a high-frequency modulated switching mode power supply unit (15) and said switching mode power supply unit (15), in accordance with the thus corrected control voltage, adjusts its output current (lines 13,14) during the respective welding operation

  • Patent number: 4792426
    Abstract: A process for precisely controlling the thickness of a heat-softenable sheet material (52) comprising heating the material to bring it to a softened condition, compressing the material while in the softened condition to the desired thickness or somewhat less and then cooling the material to a temperature below its softening point so that it sets while precisely maintained at the desired thickness. The material is cooled by passing it between substantially parallel cooling plate (32,34) rigidly spaced with a separation equal to the desired thickness of the material.
