Title: Wringers
IPC: D06F45/18
Filed: 1937-07-12
Abstract: 494,604. Wringers. TRIGGS, W. W. (Lovell Manufacturing Co.) July 12, 1937, No. 19307. [Class 138 (ii)] [Also in Group XXIV] Relates to means for quickly disconnecting the drive to a power-operated wringer in an emergency. As shown in Figs. 3 and 6 the clutch 40 is moved along the vertical drive shaft 39, for transmitting the drive from the shaft 39 to one or other of a pair of bevels 37, 38 which mesh with a bevel 36 driving the lower roller shaft 7 through a coupling 35, by means of a pin 45 eccentrically mounted on a disc 46 which may be rotated by a hand lever 48. The disc is provided with an arm 55 connected by springs 54 to a plate 51 which is caused to slide to the left or right according to the direction of rotation of the disc 46 thereby moving one of the projecting pins 50 into locking engagement with a corresponding recess 49 in the disc and so holding the clutch in one of its driving positions. Actuating bars having downwardly projecting lips adjacent the lower roller extend longitudinally along the lower roller and are secured to pivot rods 27 which extend through the side walls 3 of the wringer into the gear casing 34. The bars may be rotated by the operator or are rotated automatically by clothes wrapping round the lower roller. Plates 53 secured to extensions of the pivots 27 engage apertures 52 in the sliding plate 51 so that, on rotation of either bar in either direction, the plate 51 is moved back into its mean position and the stressed spring 54 rotates the disc to its centre position thereby moving the clutch to neutral. The plate may alternatively be restored to its mean position by the operator depressing a plunger 59 to which is secured a cam 57a which engages the plate 51. In the form shown in Fig. 11 bifurcated levers 84 are secured to the pivots 69 of the bars which extend longitudinally along the front and back of the lower roller. The bars may be operated by the operator or by the clothes wrapping round either roller. The levers 84 are connected together by a link 86 so as to work in unison and are connected by springs 83 to an arm 82 on the rotary disc 77 that operates the clutch and which is rotated for this purpose by an eccentric pin 78 moved by an external handle. A trip plate 88 is secured to another arm 79 on the disc and is provided at each end with a stop shoulder 89 which engages the connecting member 85 of the limbs of one of the bifurcated levers 84 when the clutch is in either forward or reverse drive position. When either pivot 69 is rotated due to the depression of one of the bars extending along the rollers the levers 84 rotate so as to free the plate 88 and the clutch is restored to neutral position by one of the springs 83. The levers 84 may also be operated to restore the clutch to neutral by a push-button which actuates a cross head 92 connected to the lever.

Title: New or improved apparatus for the x-ray examination of hollow metal bodies
IPC: G01N23/18
Filed: 1950-08-03
Abstract: 688,557. X-ray apparatus. DAIMLERBENZ AKT.-GES. Aug. 3, 1950 [Aug. 3, 1949], No. 19468/50. Class 98 (i). Apparatus for the X-ray examination of a hollow shell-shaped metal body with a curved cross-section comprises a movable support for the body disposed between the X-ray tube and a fluorescent screen and rotatable, substantially about the centre of curvature of the body, to bring all sections of the body successively into a position approximately parallel to the screen, and a slit diaphragm which exposes to irradiation only that section of the body which for the time being is approximately parallel to the fluoroescent screen. As shown, the apparatus is adapted for the examination of semi-cylindrical bearing shells 3 placed in piles on rotary discs. 4. Each pile is held by adjustable angle bars 5, 6 and each disc has a shaft 11 journalled in a channel-sectioned ring 12. Ring 12 is rotatable to bring each pile in turn to an examination position between the radiation aperture 20 of an X-ray tube 21 and a fluorescent screen 7. Each shaft 11 has a disc 13 which, in the examination position, frictionally engages a disc 15. A flared lead tube 22 has end walls, of which one has an aperture 24 next to the radiation aperture 20, and the other has a vertical slit 26, so that a narrow beam of X- rays passes through the shells 3 to the nuorescent screen 7. The X-ray tube is surrounded by a lead wall to protect an assistant at the rear of the apparatus, who places the shells on the discs 4 to be carried round to the examination position. An examiner protected by lead walls extending from both sides of and above and below the front wall of tube 22, rotates the pile of shells by turning a hand wheel 18 and examines each part of each shell in turn. Should a defect be noticed, the examiner raises screen 7, which slides in vertical guides, and marks the defective shell. A lead screen 36, connected to screen 7 by a cord 35 passing over a pulley 34, descends when the screen is raised to protect the examiner from X-rays. As a further protective measure, a shutter 40 on parallel links 41 is normally urged by spring to cover the radiation aperture 20, but is moved away from the aperture by a Bowden cable 47, operated by the edge of screen 7 when it is lowered. Ring 12 may be turned manually or by an electric motor controlled by switches operated by projections on the ring. The width of the part of the shell irradiated may be altered by turning it from a position facing the X-ray tube to a position facing away therefrom, and also, in some cases, by making slit 26 adjustable in width.

Abstract: 1,203,346. Towing arrangements on aircraft. UNITED AIRCRAFT CORP. 29 April, 1968 [15 May, 1967], No. 20242/68. Heading B7W. [Also in Divisions B8 and E1-E2] In a towing installation of a helicopter a hook 90 on the end of a towing cable is automatically lockable in a latch support 52 on the end of a boom 38 secured to the helicopter such that during towing all the load is taken by the boom and not the cable. The boom formed by telescoping tabular members 42, 44 is retractable and is universally pivoted at 40, 41 to the aircraft, and the towing cable passes through the boom between the hook 90 and a winch in the aircraft. The latch support 52 is pivoted at 56 to the boom so that after unlatching at 60 it depends from the boom for lowering the hook 90 to engage the line 25 of a load to be towed. Upon winching in the towing cable, the hook 90 spring latches itself into the support 52 which is then rotated about pivot 56 into its latched position in line with the boom. Rollers 98 and 102 for guiding the towing cable or the towed line 25 are mounted on a linkage arrangement 94 used to control the degree of opening of a hinged ramp 28 in the underside of the helicopter. An hydraulic jack associated with the boom acts as a damper therefor during towing and moves the boom into an upper stowed position when required. For stowage the boom is retracted by further winching in of the towing cable once a stop between the telescoping members has been withdrawn.
