Title: Helicopter cargo hook and release system
IPC: B64D1/22
Filed: 1963-04-08
Abstract: 1,036,064. Hooks. UNITED STATES OF AMERICA SECRETARY OF THE ARMY. April 8, 1963 [April 6, 1962], No. 13897/63. Heading F2H. [Also in Divisions F3 and H2] A cargo hook slung by cables beneath a helicopter (for allowing the cargo to release itself by its own weight when a cable 15 is pulled or a switch in the craft is pressed or the cargo's weight is taken by touchdown) has a pivoted tongue member 3, shown in the release position before being raised again by a spring 18 retained by arcuate covers in an arcuate hole, Figs. 5, 6 (not shown), in the tongue member. The pivot pin 5 of the tongue member 3 passes through two shank plates 2 (between which the tongue 3 can swing) and through two strengthening side cheeks 4 outside the shank plates. When the tongue 3 is raised, it is held by its notch 11 engaging a latching pin 9 pivoted by lugs 12 on a latch lever 7 controlled by the various release means and loaded by a spring to urge the pin 9 into the tongue notch. A pivoted mousing piece 23 is urged counterclockwise against a stop 25 by a spring 26 and is moved, clockwise, only when the cargo ring is slipped over the tongue end to load the hook. In another form of hook, pivoted on a pair of beam plates, Figs. 12-14 (not shown), the spring 18 may be omitted and the hook tongue 3 is re-cocked by a cable from the craft, while the latching pin 9 has anti-friction bearings for riding on the edges of the cheeks 4. In a further form, Figs. 9-11 (not shown), the tongue member 3 is in the form of two joined parallel plates swinging together outside and on opposite sides of the shank plates 2 which have clevises for suspension of the hook. The compression spring 18 is replaced by a torsion spring coiled around the tongue pivot and with its ends anchored to the tongue and shank respectively. Release.-Apart from being raisable manually by the cable 15, the latch lever 7 (which prevents the hook tongue 3 from swinging down to the cargo-release position shown) can be raised by operation of an electric motor started via a relay by a switch in the aircraft cabin or by a switch, Figs. 19-21 (not shown), attached to a hook-supporting cable and held open by the cable when taut but spring-closed when the cargo touches down. The latter switch is in series with an arming switch in the cabin. The motor rotates a screw shaft to raise a non- rotating nut which engages a shoulder, Figs. 15, 16 (not shown), on a slide bar pivoted to the end of the latch lever 7 or to raise such a nut bearing pivoted levers, Figs. 17, 18 (not shown), which engage arms on the slide bar. In either case the nut causes the latch lever 7 to rise and release the hook tongue. The switches are in a circuit, Figs. 22-24 (not shown), with a relay for starting the motor and reversing its supply and rotation (see Division H2) when the nut reaches the top of its travel and either the nut itself, or the slide bar cammed sideways, operates a switch in the relay circuit. The reversed motor lowers the nut to its original position, while the slide bar and latch lever have fallen, ready for re-use.

In joining pipes made of thermo-plastic material by welded spigot-and-socket joints, the surfaces of the parts which are to overlap are heated into a pasty fluid condition over the whole circumference and substantially along the whole length, the parts are fitted together and then cooled or allowed to cool. The softening may be superficial and to a varying depth and may be effected by a hot current of air or gas, by an open flame such as a ring burner, or by dipping in hot liquids, any parts not to be treated being protected. Cooling may be effected by quenching in water or oil, by applying such liquids by spraying or by blowing cold or cooled air on to the joint. Details are furnished of the depth of softening and of temperatures of heating and cooling. The outer diameter of the spigot may be greater than the internal diameter of the socket whereby ridges are formed immediately in front of and behind the weld. Various forms of joint are illustrated including an external or an internal sleeve welded to two pipe ends, three pipes welded to T-piece, pipes with conical ends welded together or to an internal sleeve, and a ball-and-socket joint. Apparatus for aligning the parts to be joined, and tongs for heating the parts are described.

Current is led to or from the armature by brushes bearing on the outer edges of the plates. Fig. 1 shows in part section a complete armature. Figs. 3 and 4 the arrangement of the plates and windings and Fig. 6 the method of connecting the windings and plates together. On the armature cone b, Fig. 1, are placed the involute magnetic plates c and the intervening armature windings o, the plates being either in one doubly-curved layer, as in Fig. 4, or in two singly curved layers with intervening insulation h, as in Figs. 1 and 3. The plates are insulated from each other and the windings, as at n, f, and from the armature core at m, and their outer ends are bent back at e<2> to form surfaces on which bear the brushes p. At each end the plates are bevelled at e<1> to co-operate with the correspondingly bevelled edge of a cuplike damping member c and, when two layers of plates are used, with the edge of an inner clamping sleeve c' upon which rest the overhung ends of the windings o. The edges of the plates may be bent, as at g, Fig. 3, to improve the magnetic continuity and wires l are attached to them by soldering or the like to enable them to be connected to the windings, as shown in Fig. 6 and act as a collecting surface for the brushes p. Form-wound coils are employed with their two active sides respectively in the inner and outer range of conductor belts in the usual way. The Provisional Specification states that binding wire may be placed around the magnetic plates and the cups c and that these cups may be fitted with a liquid insulator which solidifies and holds the parts of the windings in place. Also that when the ends of the windings are disposed on the exterior surfaces of the cups, binding wire is used to retain them. When the winding ends are on the exterior of the cups, the bevelled faces of the magnetic plates are arranged towards the inner edges of the plates.
