  • Patent number: 4736505
    Abstract: A method and apparatus for use in repairing or replacing parts of the suspension system, such as a MacPherson strut of an automobile which suspends a frame or passenger compartment from a lower portion which includes the wheels and the axle. The apparatus includes an elongated upright apparatus which has a piston rod extending out the top. A special mounted assembly is mounted on top of the piston rod with outwardly extending arms which exerts an upward force on the spring of the MacPherson strut. At the same time a chain is attached between the housing of the elongated tool and the frame or body to prevent upper movement of the frame. When the spring is compressed the shock absorber portion of the MacPherson strut can be removed and replaced.

  • Patent number: 4729158
    Abstract: An apparatus and method for interconnecting a drill collar and a stabilizer in axial alignment is disclosed. The tool includes an upper plate and a lower plate held in spaced, parallel relationship to one another with the upper plate having a plurality of peripheral holes around it.

  • Patent number: 4625377
    Abstract: This invention relates to metal cutting and more particularly to method for manufacturing constant velocity universal joints. A construction is disclosed wherein spherical turning, milling and grinding of the races and grooves of the joint members of a universal joint are performed on common machines without removing the workpieces and the workpieces are held in common workheads. During the machining operations, relative movements between the tools and workpieces are referenced to common axes thereby duplicating the relative positions and movements between the workpieces during actual service. The inventive concept provides a means for achieving consistent product quality and is adaptable to the automated manufacturing of constant velocity universal joints.

  • Patent number: 4614105
    Abstract: A helical baffle for shell and tube type heat exchangers is fabricated by stamp forming a plate in the form of a partial circular section into a helical section between opposed, mating helically-shaped faces of two forming dies. The plate contains a series of apertures in the form of a pattern for receiving heat exchanger tubes. The dies contain sleeves and opposed reaming rods which form lips on the apertures during stamping of the plate. Lips can also be formed on the outer edge of the plate and the edge of a central passage during stamping. The lips prevent the helical plate from twisting or returning to a flat configuration. The leading and trailing edge of the helical plates are then joined such as by riveting or welding into a continuous helical baffle with sets of heat exchanger tube apertures aligned along a common axis.

  • Patent number: 4614030
    Abstract: An apparatus for automatically processing the wire ends of cores includes a forming die for bending the axially projecting wire ends back to project parallel to one another generally away from the core. Cores are received in a receiving station aligned with the forming die and orientated so that the wire ends are spaced as far as possible from the die. When the wire ends are sensed to be in the correct orientation, an actuator is operated to push the core through the forming die. The core with its wire ends bent back is then preferably stepped through a series of processing stations to trim and tin the wire ends and then ejected from the machine. A series of cores can be stepped continuously one after the other through the machine.

  • Patent number: 4612702
    Abstract: A method and apparatus for winding field coils on internal poles of stator bodies, particularly for electric motors, have a magnet wire feeding needle or needles displaced eccentrically from the central armature axis of the stator body. The or each such feeding needle is disposed to reciprocate and partially rotate on an eccentric axis located between the central armature axis and the internal pole being wound. Due to this eccentricity, during the partial rotation of the feeding needle, the end turns of the coil are lifted above the end of the pole and laid more precisely in place. This enables the conventional winding forms to be eliminated allowing a reduction in the length of the reciprocating stroke of the feeding needle and faster winding with reduction in "snap back" effect. A further cost saving occurs from a shorter length of the end turns resulting in less wire being used.

  • Patent number: 4603459
    Abstract: A rocker bushing for a roller structure for supporting a boat on a trailer bed and having a male and female member formed of two cylindrical portions surrounding the shaft and supporting the roller. Each cylindrical member having a tapered longitudinal portion but terminating in a radially outwardly extending stop flange of increased radial thickness. The bearing surface of the rocker bushing positionally adjacent to the shaft is curved to allow the roller to gimbal or wobble to engage the angle of a boat hull. The integral construciton of the rocker bushing provides support across the entire width of the roller.

  • Patent number: 4603458
    Abstract: A roller used for a roller conveyor which includes an outer cylinder of the roller supported by a pneumatic bearing. The roller also includes a fixed shaft having a path for letting air pass through in the center thereof, and annular members fitted on the fixed shaft, the outer cylinder covering the shaft and annular members leaving a narrow gap around the annular members. The path for letting air pass through the shaft and the narrow gap communicate with each other by way of holes and a groove made on the annular members. Therefore, the introduced air can pass through the holes and the groove and then fill the narrow gap to such an extent that the wall of the outer cylinder never comes into contact with the annular members, the thin layer of air in the gap functioning as the pneumatic bearing.

  • Patent number: 4599780
    Abstract: A method for adding a compartment to a commercially available mini-truck vehicle includes the steps of cutting the frame rails of the original vehicle to separate the front and cargo sections and then extending the chassis by adding extension members which are welded to the cut rails. A frame platform is emplaced on the extended sections and a fiberglass compartment is secured to the frame platform. The resultant vehicle possesses the same contours as the original vehicle while the added compartment allows at least two additional passengers to be transported.
