Abstract: 382,569. Sewing-machines. FAIRWEATHER, W. C., 65, Chancery Lane, London.-(Singer Manufacturing Co. ; Elizabeth, New Jersey, U.S.A.) May 12, 1932, No. 13661. [Class 112.) Needles, vibrating laterally.-The needle-bar carrier and looper-carrier are vibrated in a vertical plane about a common horizontal pivot. More room is provided under the gooseneck for the accommodation of the work. The oscillating needle-bar carrier 6 having upper and lower bearings 7, 8, is pivoted on a stud 5 on the head 4. The reciprocating needle-bar 9 carrying the needle 10 works in the bearings 7, 8. The needle-bar is reciprocated by the link 13 and lever 14, the rear end of the lever 14 being connected to a crank 17 on the main shaft 18 by a pitman 16. The looper 36 has the usual loop-taking beak 37 and loopspreading wing 38. In the form illustrated, the machine forms a chain stitch and the looper rotates. The looper is secured to a shaft 39 journalled in a block 40 slidably held between plates 41, 42. A bifurcated member 46 is secured to the end of the looper shaft. The bifurcations 47 are engaged with bifurcations 48 on the main shaft by a bakelite intermediate block 50, the block having grooves longer than the bifurcations to permit axial movement of the looper. Fixed to the needlebar carrier 6 is a curved arm 52 enlarged at its lower end to form an elongated slot 53. The enlarged end carries a bracket 55 to which is fixed an arm 57 which is in turn fixed to the looper-carrier 40. This arrangement couples the looper and needle so that they vibrate in unison. The main shaft carries a pinion 59, Fig. 5, meshing with the toothed gear portion 60 of a barrel cam 61 rotating freely on the shaft 611. The ratio of the gearings is 1 : 2, the cam 61 rotating at half the speed of the main shaft. The cam 61 has a cam race 62 into which extends a follower 63 mounted on a lever 64 fixed to the shaft 65. This shaft carries a lever 67 having an elongated slot 68. A stud bolt 70 working in the slots 68, 53 enables the side throw of the neddle bar and looper to be varied. The cam race 62 is shaped so as to give the needle a dwell at the extreme ends of its lateral vibration, to enable it to penetrate the work vertically. Presser bars with periodic control.-The presser bar 20, carrying the foot 21, has the usual manual lifting lever. It is lifted automatically by the lever 27 actuated by a pin 34 on the lever 14 carried by a block so that it can be placed in operative or inoperative position.

Title: Improvements in and relating to airplanes
IPC: B64C3/50
Filed: 1922-05-16
Abstract: 180,996. Dayton-Wright Co., (Assignees of Wright, 0. and Jacobs, J. M. H.). May 31, 1921, [Convention date]. Planes, construction of; steering and balancing. -The camber of the lower surface of a plane is changed without changing the camber of the upper surface, by constructing the lower surface of a part or the whole of the trailing edge in the form of a pivoted flap 34, Fig. 5, which may be moved away from or towards the upper surface 31. In the construction shown in Fig. 9, both the upper and lower surfaces of the trailing edge are formed as flaps 55, 54, pivoted at a common point 56 on the main portion of the plane. The camber of the lower surface is adjusted by movement of the flap 54 relative to the flap 55, after which lateral balancing may be effected by moving both the flaps together while maintaining the angle between them fixed. A modification is also described in which the lower flap is pivoted to the upper flap. The method of control is illustrated in Fig. 12, which shows part of the fuselage 53 of an aeroplane fitted with right and left planes 51, 51<1> constructed as shown in Fig. 9. The camber of the lower surfaces of the planes is adjusted to obtain the required lift, by lowering the under flaps 54, 54', simultaneously and to an equal extent, by winding a crank 68, which rotates a winch 62 on which are wound the controlling wires 61, 61<1> from the lower flaps. These cables 61, 61' extend over pulleys 72, 72<1> mounted on a triangular plate 77 attached to the control shaft 74, through which they pass to the winch 62. Springs 60, 60' are provided for raising the lower flaps 54, 54' when the cables are unwound from the drum, or the air-slip may be depended upon to do this, the springs being dispensed with. The winch 62 may be driven by the engine or by a separate motor. The lower flaps are locked in position by a pawl 70 engaging a ratchet 69 on the crank-shaft. The upper flaps 55, 55<1> are connected together by a compensating cable 82 and are controlled by cables 80, 80' fixed to the plate 77 at points adjacent to the axes of the pulleys 72, 72'. The control stick 90 is pivoted to the shaft 74 in the usual manner, so that the shaft 74 may he rotated and the plate 77 thereby moved to the left or right. All the control wires 61, 61<1>, 80, 80<1> are thus acted upon to raise the flaps of the right plane and lower those of the left plane, or vice versa, without changing the first-adjusted angle of lift between the two pairs of flaps. The control stick 90 is also pivoted at 91, the elevator controls 94, 95 being operated by a forward or backward movement. According to a method of constructing the flaps shown in Fig. 13, their inner surfaces are left uncovered and the ribs 104, supported on the spars 100, 103, are made almost as deep as the total depth of both flaps, the ribs of the two flaps passing one another when the flaps are together, after the fashion of the blades of shears.

[Class 38 (iv)] [Also in Groups XXXVII and XXXVIII] Voltage.-In a system in which a controlling quantity produces unidirectional current, dependent on the magnitude and sense of variation of the quantity, which is supplied to responsive means for exercising a desired control, components dependent on the first differential of the current are added by phase advancing means comprising two magnetically linked windings, one in series in the D.C. control circuit and the other in a local circuit connected to the responsive means. A component dependent on the second differential may be provided for alternative or additional use, by further phase advancing means such as a condenser, or a phase advancing metadyne arranged as described in Specification 592,209. The invention is applicable for automatic self-regulation such as voltage regulation of dynamo-electric machines. As shown in Fig. 1, the D.C. control is applied over leads 2, 3 to a winding 1 which may be the field winding of a motor or a variator winding of a metadyne supplying a D.C. motor. The phase advancing means comprises a series winding 4 and a magnetically linked shunt winding 5 which supplies a component dependent on the rate of change of the current in winding 4 aiding that current when it is increasing and opposing it when decreasing. Modifications introducing the second differential comprise a phase advancing metadyne connected in series with winding 5 in a shunt circuit or connected in a second short-circuit in series with a further winding coupled to 5. In a further modification, Fig. 6, the winding 5 is connected to a second control winding 10 with or without further phase advancing means such as metadyne 6. It is arranged that the components at frequencies above which the phase advance becomes'zero are small. Specification 604,185 also is referred to.

Abstract: 771,236. Moulding hollow articles from thermosetting materials. TURNER BROS. ASBESTOS CO., Ltd. May 13, 1954 [May 18, 1953], No. 13918/53. Class 87(2). A plastic composition is applied as a coating to a former which is then put in a closable space, the remainder of the space is then filled with a thermally expansible liquid and with the space closed the assembly is heated, where. upon the liquid expands and pressure is applied to the exposed surface of the composition solely by the expansion of the liquid brought about by the heatiiig. The apparatus shown is used to make a funnel-shaped article from a composition of asbestos fibres and thermosetting resin. The. material 3 is applied to the surface of a metal former 1 which is fitted in a casing 5 and held in place by a cover plate 10. The coating is applied by hand or with the aid of shaping devices. The former is centrally bored to receive an electric heating element 22 ; heaters 23, 24 are also fixed to the side and bottom of the casing. The space between the coated surface of the former and the inside of the casing is made liquid-tight by rubber sealing rings 8, 9 and a tight-fitting metal ring 7 below the cover. In operation, a pressurecontrol valve 15 is first opened and mercury is admitted from a pipe 18, through a three-way cock 16 to the inside of the casing until it flows out through the valve 15. This valve is then shut and adjusted to the release pressure required and inlet and outlet cocks 16, 17 are also closed. Current is then supplied to the electric heaters, causing the mercury to expand and apply heat and pressure to the material 3, which is thus cured. The three-way cock 17 is then opened and the mercury run out through the pipe 20. The cock 17 is closed and the cock 16 opened to admit cooling water from the pipe 19, which is afterwards run off through the pipe 21 on re-opening of the cock 17. The cover 10 is then removed and the former 1 with the completed article is withdrawn through the opening in the top of the casing. Aircraft wings may be moulded by this process.
