  • Patent number: 5617925
    Abstract: A tool for driving a nail or other fastener is actuated by a caseless propellant charge formed of combustible material that is transported into a combustion chamber on a strip. The propellant charge is ignited by striking a sensitizer portion of the charge at an oblique angle. The ignition member intermixes the sensitizer material with an oxidizer layer of the surface of the propellant charge, resulting in combustion of the charge. When ignited, the propellant charge is compressingly interposed between an orifice plate and a movable portion of the combustion chamber. The orifice plate includes a pedestal with an annular compression surface that separates the surface of the ignition area from the remaining surfaces of the charge, insuring that ignition gases are forced through the charge. An annular C-shaped ring is interposed between the orifice plate and the movable portion of the combustion chamber.

  • Patent number: 5175990
    Abstract: An endless conveyor for ring spinning machines comprises bobbin pegs (13) for receiving full and/or empty bobbins which seen in the conveying direction of the endless conveyor (17) must assume an exact position on the endless conveyor (17) in order in a predetermined bobbin change position to come into alignment with a spinning point (11) or other bobbin support arrangement and thus ensure a perfect bobbin transfer from or to the bobbin peg (13). Each bobbin peg (13) is mounted on the endless conveyor (17) adjustably in the conveying direction via a driver (19).

  • Patent number: 5170616
    Abstract: A textile machine has a bank of spindles each provided with a flyer having a presser finger and a fork having a plurality of elongated teeth thereon for simultaneously removing full bobbins from the spindles and for supplying empty bobbins to the spindles. A safety device is provided for moving the presser fingers out of the paths of the empty bobbins as the empty bobbins are inserted into the flyers, comprising deformable elements extending longitudinally of the teeth of the fork. The presser fingers have members thereon so positioned as to be engaged by the deformable elements and to swing the presser fingers out of the paths of the empty bobbins when the empty bobbins are inserted into the flyers by movement of the fork in one direction.

  • Patent number: 5014505
    Abstract: The grippers are mounted on a doffer bar so as to disengage from both the top and bottom of the bar should a mis-alignment occur relative to a bobbin tube. The removal or separation of a gripper from the bar causes a pneumatic or electrical signal to be generated which can be used to indicate the individual disturbance location. A light may also be provided at each gripper station in order to indicate a position of a disturbance.

  • Patent number: 4947632
    Abstract: The machine comprises a series of rotatable spindles (3), each of these being associated with respectively one cap-shaped thread guide member (7) rotatable about the spindle axis. A first drive belt (5) serves for turning the spindles (3). A second belt (12) is in contact with whorls (11) on the thread guide members (7). A device exerting contact pressure (13, 14, 15) urges the second belt (12) during operation against the whorls (11) with an adjustable force so that the belt (12) exerts, by means of friction, a small braking force on the whorls (11) running faster than the belt (12). The contact pressure device (13, 14, 15) can be switched over in order to press the second belt (12) against the whorls (11) with a substantially greater force. Upon shutoff of the spinning machine, the contact pressure device (13, 14, 15) is switched over so that the decelerating second belt (12) exerts a substantially greater friction force on whorls (11) and rapidly brakes the thread guide members (7) concomitantly.
