Patent GB-772956-A (GB)
Title: Improvements in or relating to a tying machine assembly
IPC: B65B13/10
Filed: 1954-04-22
Abstract: 772,956. Package-tying machines. BUNN CO., B. H. April 22, 1954 [Sept. 29, 1953], No. 11642/54. Class 94(1). In a machine of known type comprising a package-supporting table 10 and an intermittently rotated twine carrier 18 which is driven from a motor 30 through a clutch 36, shaft 35 and mutilated gear 38 meshing with a gear 39, the engagement and disengagement of the clutch is controlled by a lever 68 arranged in an opening in the table so as to be depressed by a package 71 positioned on the table against an abutment 16 by the operator. In one form, Figs. 5 and 7, the clutch-operating lever 47 carries a roller 51 which is actuated by a cam 53, driven in synchronism with the gear 38, through a pivoted follower 57 and a slidable link 56 coupled to one arm of a spring-loaded bellcrank lever 64. The other arm of the lever is coupled by a rod 66 to the lever 68, so that when the latter is depressed by the package, the link 56 is withdrawn from between the roller 51 and follower 57 and the clutch is allowed to engage under the action of its spring. When the tied package is removed, the link 56 is interposed between the roller and follower and the cam then operates to disengage the clutch. In a second form, Fig. 9, the rod 66 is replaced by a floating link 74 having its upper end engaging the under surface of the lever 68 under the action of a spring 79 and its lower end engaging a roller 73 on the bell-crank lever 64a. The link is formed with a cam surface 80 which engages a screw 81 under the action of a spring 82, so that after the lever 64a has been operated to allow engagement of the clutch, the lower end of the link rides off the roller and allows the lever to be restored to its initial position under the action of the spring 72. With this arrangement, the clutch is disengaged after one complete revolution of the cam 53, even though the lever 68 remains depressed by a package. The gear 39, Fig. 12, carries a pivoted shoe 86 which engages a cam surface 89 on the gear 38, so that the twine carrier 18 is brought to rest in a predetermined position after each rotation. The twine carrier is also acted on by a friction brake, (see Fig. 3A (not shown)). The twine is fed to the carrier from a supply 20,through an aperture plate 25, Fig. 2, and is tensioned by a leaf spring 27 whose convex end 29 engages the twine above the aperture. Specification 449,019 is referred to.

The upper bearing 23 is carried by double. girders 24 mounted on vertical pivots 25, so that they can be swung aside when it is desired to remove the shaft. The driving-mechanism is carried by a framework 6 mounted on girders in the foundation of the furnace. The lower part of the furnace is closed by a collar 2 in which work scrapers for removing dust &c. When the shaft is to be removed, the bolts 27 7 are disengaged, the girders 24 are swung aside, and a pulley hoist is connected to the upper end. By lifting and rotating simultaneously, the shaft with the arms can be removed bodily.

Abstract: 329,783. Crook, L. H. April 17, 1929. Balancing; planes, construction of.-The airflow over a main wing is controlled automatically by vanes pivoted to oscillate within certain limits at the leading or trailing edge or at both the leading and trailing edges of the wing, friction elements being provided to resist the free movement of the vanes in intermediate positions. Pivoted vanes also may be mounted in central openings in a main wing. Fig. 1 shows a crosssection of a wing 26 having a pilot plane 30 pivoted at 41 and a trailing plane 35 pivoted at 46. Both planes have rigidly mounted auxiliary surfaces 33, 42, 43 to stabilize their movements and the forward plane is limited in its upward movement by a stop 31. Movement of the rear plane is limited by a solid hook or by a tension spring. Other modifications are described in which the auxiliary surfaces act as limiting stops, and the trailing planes in certain instances have flexible and slit feather edges at the rear or at both the front and rear. Fig. 5 shows a symmetrical plane 75 with pilot and trailing planes 78, 82 pivoted on the axis of the main plane. In this case both pivoted planes have two auxiliary surfaces, those on the rear plane acting as stops, and the rear plane has feather edges 86, 87. The free movement of the planes is resisted by springs and friction discs on their spindles. Fig. 14 shows a plane 113, pivoted at 112, which normally closes a gap in a main plane 110, but is adapted to open a slot as the incidence increases. The plane 113 may have auxiliary surfaces fixed to it below, or above and below. Movement is limited by a stop 114, or a pin on the spindle may engage a circumferential slot in a tubular bearing.

Abstract: 108,550. Storie, J. Aug. 25, 1916 Jib cranes.-The lowering tackle used with luffing davits is provided with means for compensating for the lowering of the davit head and also for the listing of the vessel. In the arrangement shown indicating the adjustable pulley 16 on the normal or even keel position, the standing part of the lowering fall 22 passes over a pulley 23 on the davit, around a pulley 11 about two sevenths up the davit and around the pulley 16 to a fixed point 24 on the davit. The number of falls between the pulleys 11 and 16 is twice the number of falls in the boat tackle. The pulley 16 is mounted on a pivoted arm 13 having two holes 18 through which a pin 19 may be passed into one or other of the holes 20<d>, the arm being connected by bevel gearing to the corresponding arm on the other davit. In the event of the vessel taking a backward list. the pulley 16 is moved to one of the outboard positions and for a forward list the pulley is moved to one of the inboard positions. Instead of the standing part of the fall, the hauling part may be used or the top block may be suspended by a separate cable. In a modification using a davit of the rolling quadrant type, the adjustable pulley is mounted on a curved rail. To compensate for the list of the ship in davit tackle fitted with known types of gear for compensating for the lowering of the davit head, alternative points of attachment or alternative fixed or adjustable pulleys are arranged on the framework.
