  • Patent number: 7125209
    Abstract: The present invention provides an improvement (20) in a Davenport® automatic screw machine having a stationary spindle. The improvement broadly includes a quick-change mechanism (26) associated with the stationary spindle (22). The mechanism includes mating frusto-conical first and second surfaces (28, 31) on the spindle and tool holder, and a multi-lead threaded connection (32) between the tool holder and stationary spindle such that the tool holder may be quickly locked into mating engagement with the stationary spindle by relative rotation therebetween through a short angular distance. The invention may also include an adjustment mechanism (33) that allows the axis (x2—x2) of the tool to be aligned with the axis (x1—x1) of a spaced rotatable spindle. This adjustment mechanism includes a base member (34), an adjustment member (35), and a locking mechanism (37) for selectively holding the adjustment member in the desired position relative to the base member.

  • Patent number: 6508095
    Abstract: An improved end-working attachment (30) for a screw machine or a rotary transfer machine is particularly suited for use in rolling threads on a workpiece. The attachment broadly comprises: a slide base (31) having an axis (y-y); at least two members (32, 32) mounted on the slide base for sliding movement in a radial direction toward and away from the slide base axis; a tool, such as a thread die (33), on each member; an infeed mechanism (34) for selectively causing the slide members to move toward the slide base axis such that said tools will engage said workpiece; and a return mechanism (35) for urging the members to move away from the slide base axis.

  • Patent number: 6202461
    Abstract: The attachment includes a generally U-shaped bracket having a pair of roll arms which are pivotally mounted intermediate their ends on the outer ends, respectively, the two arms of the U-shaped bracket. Each roll arm has a thread roll rotatably mounted on its outer end and a roller follower rotatably mounted on its inner end. The bracket is secured on the slide of a screw machine for reciprocation thereby in a direction selectively to engage the thread rolls tangentially with diametrally opposite sides of a rotating workpiece that is to be threaded.

  • Patent number: 5193366
    Abstract: The device includes two elongate, identical members hinged together at one end, and having locking tabs projecting from their opposite ends for securing to two members in a closed position in which confronting operating surfaces there are secured over diametrally opposite sides of a garden hose at two axially spaced sections therealong. The confronting operating surfaces of said members have therein a first pair of semicircular, complimentary recesses surrounding a cylindrical coupling on one end of the hose, and having in the bottoms thereof coaxial, arcuate grooves in which diametrally opposite sides of the coupling are seated to prevent removal from the closed members. Another pair of confronting recesses in said operating surfaces frictionally engage diametrally opposite sides of the hose adjacent its opposite end to lock that end of the hose.

  • Patent number: 5003634
    Abstract: A pair of straps project from opposite ends of a pouch for use in securing the pouch around a person's waist with an elongate opening in the pouch positioned above the person'seat. The opening is releasably closed by two separate (inner and outer) zippers. An elongate panel or sheet of flexible, waterproof material is secured at one end of one edge of the pouch opening to extend downwardly out of one (the outer) zipper into an operative position beneath one's seat, where it can be secured in place by two other straps which fasten around one's legs. At such time the other or inner zipper may be closed to retain personal items, (comb, sunblock lotion, etc.) in the pouch. When not in use the waterproof panel is rolled up and stored in the pouch.

  • Patent number: 4766750
    Abstract: The wedge-shaped operating member of a thread rolling attachment is reciprocated by a piston rod which extends into one end of a fluid pressure cylinder. A rotatable valve stem is mounted intermediate its ends in the opposite end of the cylinder for limited axial movement, and has thereon a valve seat normally closing a port which leads to a reversible valve that directs fluid under pressure selectively to opposite ends of the cylinder to shift the piston rod between retracted and advanced positions. The inner end of the stem is slidably connected to the piston rod so that when the latter reaches its advanced position it momentarily unseats the valve seat from the port to effect reversal of the valve and consequent return of the piston rod. The valve stem is rotatable to adjust the length of the stroke of the piston rod.

  • Patent number: 4617816
    Abstract: An outboard thread rolling attachment for an automatic screw machine for rolling a pattern on a workpiece comprising:a roll arm yoke; a pair of roll arms supported by the yoke end diametrically opposed to each other relative to the axis of rotation of a workpiece placed therebetween; each roll arm having a rotatable shaft with a thread roll positioned at the lower end of each shaft; fluid pressure means including a first cylinder element, a first piston element and a wedge element connected to the roll arm yoke and in contact with and operable on and between the inner end of the roll arm.The first piston element comprises a second movable cylinder element and a second piston element having adjustment means for adjusting the travel of the wedge element.

  • Patent number: 3972212
    Abstract: The holder comprises a first section containing in one end a slot in which a single knurling tool is mounted to rotate about a first axis. The first section is integral with and offset from a second section of the holder, which is used to mount the holder on the cross slide of a lathe, or the like, so that as the tool is advanced at right angles toward the work, it will be held for rotation in the holder about an axis inclined approximately 30.degree. to the axis of the work, and will pass beneath and in tangential contact with the work to knurl the work surface as it passes transversely beneath it. Alternatively the holder can be mounted on a turret in an end working position for swinging movement transversely beneath the work.
