Needles, vibrating laterally; buttonhole sewing-machines. - In a vibratory needle-bar machine, means are provided for varying the operative radius of the needle - bar gate vibrating crank without stopping the machine. The device illustrated as applied to a buttonholing machine. The needle-bar 5-is reciprocated from the main shaft 9 by the usual linkage 25, 26, and is carried in the swinging gate 7 pivoted at S. The gate is oscillated to give the needle bar its vibratory movements from the main shaft 9. It is connected by the link 10 to the slotted arm 11 pivoted at 12 to the standard 3, and connected by the link 13 to the crank pin 14 fixed to the slide plate 15 in the guide head 16 carried on the hollow vertical shaft 17. The guide head receives semi-rotational impulses from the shaft 9 through gears 18, shaft 19, star wheel 20, pins 21 and bevel gears 22, 24. The gear 22 carrying the pins 21 is driven at half the speed of the shaft 9. To vary the amplitude of the vibration of the needle gate, a rod 27 is moved in the vertical hollow shaft 17, causing its inclined end 28, Fig. 7, to move slide plates 31, 32, secured to the plate 15 forwards or backwards, so shifting the crank pin 14 diametrically of the head 16 and altering the throw of the link 13. The angle of inclination of the end 28 is made sufficiently small as to prevent the stresses on the plate 15 moving the rod 27. The plates 31, 32 are provided with suitable stops. The lower end of the rod 27 is engaged by a fork 42 at one end of a pin 43 journaled in the boss 44 in the free end of a lever 45 fulcrummed at 46 on the standard 2. A follower 48 is adjustably carried by the lever 45 and is periodically lifted by the cam plates 49 on the gear wheel 50 fixed to the vertical shaft 51 carrying the main feed wheel 52 connected in the usual way to shift the work clamp 53.

Filed: 1968-05-27
Abstract: 1,168,764. Laying under-water pipe lines. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 27 May, 1968 [29 May, 1967], No. 25153/68. Heading F2P. A method of connecting a flowline, having a major portion adapted to lie along the floor of a body of water to an offshore installation supported on the floor of the body of water and extending above the level of the body of water, comprising positioning an end portion of the flowline along the floor of the body of water adjacent to the offshore installation, restraining the flowline from movement in a vertical direction at a fixed distance from the end of the flowline, lifting the portion of the flowline extending beyond said location of restraint, maintaining the radius of curvature of the bend above a predetermined minimum to prevent buckling of the flowline, continuing lifting the flowline until the portion of the flowline extending beyond the location of restraint reaches a selected angle with respect to the floor of the body of water, and attaching said portion of the flowline extending beyond the location of restraint to the offshore installation. As shown, a bending guide 10 is lowered over a pipeline 12, which has been lowered on to the sea bed beside a platform 17, with a bending shoe 11 of the guide astride the pipe 12 which is preferably retained in the shoe by a latch 21. The guide 10 is secured to the sea bed by augers 15 which are adapted to be driven into the sea bed by mechanism manipulated either by divers from the sea bed or from the platform 17. The guide may be attached directly to the platform or be secured to the sea bed by suction pads. A draw line 18 is secured to the pipe 12 by a clamp 19 and is secured to a hoisting winch 20. The guide 10 may be positioned over the pipe 12 by a diver or lowered along a rail 27 on a leg of the platform 17. The winch can lift the pipe 12 which bends round the curved shoe 11 until the pipe is vertical, the pipe then being secured by clamps to a leg of the platform 17 so that it can be connected, e.g. to the output of a well or to another pipeline, a latch 23 preferably also being used at the upper end of the shoe 11. For long lengths of pipe extending beyond the guide 10 an additional draw line and winch may be employed. The flowline 12 could be bent upwardly for only 45 degrees. In a modification, Fig. 8, not shown, the anchoring means (25) is situated on one side of the shoe 11 so that the other side is open to receive a pipeline (12) when it is shifted laterally. The shoe 11 may have a curved extension for bending a pipeline horizontally before it is bent upwardly. Instead of the guide 11 a tubular guide sleeve (30) with a helical slot (36), Fig. 11, not shown), may be employed, the slot closing on the inside of the curve to limit the bending to that desired. The slot (36) may be replaced by a series of evenlyspaced slots (32), Fig. 13, not shown, or the sleeve may have evenly-spaced bands along it. Alternatively, the ends of a slack chain length may be welded to the underside of the sleeve.
