Title: Button attaching machine
IPC: A43D93/00
Filed: 1920-12-01
Abstract: 174,011. Fairweather, W., (Singer Manufacturing Co.). Dec. 1, 1920. Setting buttons; feeding.-In a machine for attaching buttons, particularly of the type described in Specification 175,129, the buttons are fed into a hopper 7, in which revolves an improved feed-wheel 10 on a spindle 9, having teeth 28, of rhomb-shaped cross-section, projecting from the periphery of the wheel so that a line continuous with their advance edges 32 passes in advance of the centre of the wheel. The front edges 32 of the teeth are longer than the rear edges 31, and the spaces 30 between the teeth slope downwards towards the button shoot 26. The teeth therefore make a more obtuse angle with the shoot than if they were radial, and this, coupled with the backward and downward slope of the edges of the feed-wheel between the teeth, ensures smooth feding and minimizes jamming. The teeth gather buttons and deposit them on the inclined feed-shoot 26, which has a groove 27 in which hang some of the shanks. Buttons not so positioned are swept back into the hopper by a finger 74. The buttons leave the feeding-shoot 26 with their shanks hanging downwards in the slot 27 and slide by gravity down the shoot 5, under the cover-plate 6, until arrested by the forked finger 71. The cover-plate 6 has a groove 69<1> to allow the passage of buttons having shanks passed through them and clenched on top. To give the feed-wheel 10 its step-by-step rotary motion, a ratchet wheel 11, Fig. 4, is rigidly secured to the spindle 9, and rotatably mounted on the spindle are two discs 14, 15, Figs. 1 and 2, carrying spring-pressed pawls 12, 13 respectively. The disc 14 is connected to a cam 18 carried by the main shaft 19, by a rod 17, and the disc 15 by a similar rod 16. The pawls act on the ratchet-wheel 11 to turn it in a single direction at each rocking movement of the shaft 19 and cam 18. Pins 24, 25 are secured on the pawls 12, 13 and co-operate with a two-ply disc 22. mounted loosely on the shaft 9 and connected with the hopper lid 8 by a link 23. The two-ply disc has peripheries of different radii and when the lid 8 is raised, thereby rotating the disc, the pins 24, 25 track the peripheries of larger radii as shown in Fig. 4, disengaging the pawls from the ratchet and suspending the rotation of the feedwheel 10.

Title: A method of forming a wheel-rim mounting element
IPC: B60B23/12
Filed: 1957-09-02
Abstract: 831,241. Making wheel rims; corrugating; stamping. TRIGGS, W. W. (Goodyear Tire & Rubber Co.). Sept. 2, 1957, No. 27621/57. Classes 83 (2) and 83 (4). [Also in Group XXXIV] A method of forming an axially corrugated annular rim mounting element from an annular band with no substantial reduction in thickness comprises the steps of supporting an annular band of rigid formable material on a first section of a forming die, moving a second section of the forming die axially toward the first section to engage and corrugate the annular band, simultaneously rotating the die sections with respect to each other a distance substantially equal to the difference between the horizontal and running distances between corresponding points on the mounting element, and causing the annular ring to move radially inwardly between the die sections as they close and rotate to permit the diameter of the element to reduce during forming by an amount necessary to provide for the difference between the horizontal and running peripheries of the finished element without reducing the thickness of the band. A steel ring blank 15 is placed on a lower die 12 to lie along the outer periphery thereof, and an upper die 11 is then moved down to engage the ring 15. One of the dies rotates relatively to the other during this downward movement so that sawtooth projections 16 on the die 11 mate with similar projections 17 on the die 12. As the dies close and simultaneously rotate, the ring 15 moves inwardly to compensate for the length of the ring taken by angular displacement thereof. The ring is thereby formed with a series of helical segments 3, 4, 5 and 6 and the thus formed element 2 is welded, riveted or otherwise secured to the inner periphery of a rim 1 and the segments 3, 4, 5 and 6 engage corresponding grooves on a wheel on which the rim 1 is mounted so that relative rotation of the wheel and rim result in relative axial movement thereof.

Abstract: 1,174,497. Jet flaps on aerofoils. GIRAVIONS DORAND. 15 June, 1967 [20 June, 1966], No. 27653/67. Headings B7G and B7W. [Also in Division F2] A jet flap comprises a jet outlet at the trailing edge of an aerofoil 1, a rigid flap 4 hinged by a pivot (6), Fig. 1 (not shown), to the aerofoil aft of the jet outlet, a flexible member 2 forming a continuation of one wall of the jet outlet and attached to the trailing edge of the flap 4, and operating means, e.g. a rod 9, to pivot the flap 4 up and down, and thereby flex the member 2 to deflect the jet accordingly. The rigid flap 4 may have pivoted at its trailing edge a section 11 to which the member 2 is rigidly attached. To prevent flutter there may be a dome headed member 12 urged against the member 2 by a spring 15 when the member 2 is not deflected. As the member 2 is tensioned when deflected, the rigid flap 4 may comprise telescopic elements, Fig. 6 (not shown), which are sprung to tension the member 2 at all times. The pivot (6) may be carried on the aerofoil 1 by lugs (7), Fig. 1 (not shown), which form continuations of the aerofoil ribs. The member 2 and the rigid flap 4 may each be divided into elements spanwise, the links 9 being controlled in unison by a spanwise rod 19 via bell-cranks 18. The aerofoil may be an aeroplane wing or a blade of a helicopter lift rotor. If the aerofoil were a helicopter blade the flap would be moved cyclically, and the tendency of the flexed member 2 to return to its undeflected position may be, at least partially counteracted by the centrifugal force on masses 20 located on the bell-cranks.
