Title: Epicyclic change-speed gearing for motor vehicles
IPC: F16H3/66
Filed: 1958-04-30
Abstract: 846,354. Change-speed epicyclic gear. SIRA SOC. INDUSTRIALE RICERCHE AUTOMOTORISTICHE. April 30, 1958 [May 4, 1957], No. 13797/58. Class 80 (2). In a motor vehicle change-speed epicyclic gear having gradual clutch engagement, as for automatic starting, plates 40, 41 of friction clutches driving suns 44, 48, respectively, are selectively clutched to an input cylinder 10, in opposition to undulating wire springs 19, by the centrifugal pressure of oil supplied constantly to chambers 13, 14 of actuating pistons 15, 16, through conduits 34, 35, 39, the chambers 13, 14 being selectively evacuated for declutching through peripheral valve ports 23, 24 opened by the attraction of spring-loaded closure-rings 25, 26 by electromagnets 30, 31 energized through slip-rings 32, 33. The strength of the springs loading the rings 25, 26 limits the centrifugal oil pressure to avoid excessive friction clutch loading at high speeds by allowing some of the oil to escape from the chambers. The diameter of the conduits 39 and the shape of the chambers are suitably chosen to avoid shocks due to excessively sharp clutching or slipping due to slow clutching. The suns 44, 48 mesh intermeshed planets carried by a freely-mounted carrier, one planet meshing a ring-gear 49 fast on a final output shaft 2. Electromagnetic brakes 53, 54 hold the carrier and sun 48 respectively. Two reduced ratios, direct drive and one reverse are as follows:-First speed, clutch 40 drives the sun 44, brake 53 holds the carrier. Second, clutch 40, and brake 54, hold the sun 48. Direct drive, clutches 40, 41. Reverse, clutch 41 driving the sun 48, and brake 53 on the carrier. In neutral, the clutch 40 remains filled. During gear-shift, gripping the shift lever energizes the clutch magnets 30, 31 to ensure the draining of both chambers and the release of both clutches, and engine speed is maintained above that required for centrifugal clutch engagement by means not described.

Abstract: 246,712. Huxtable, W. G., and Gold, R. E. May 27, 1925. Machines using continuous wire.- In apparatus for attaching wire hinge members to metal boxes or metal parts a length of wire is cut off, bent to staple form, and forced into the box without previous perforation. A box A, Fig. 4, is supported on a holder 17 in which works a spring held slide 18. A slide 10 is mounted on pins 34, Fig. 2, in plates 35 having studs 36 engaging L-shaped slots 37 in the machine base plate, and operates as a driver. A slide 11 can move with the slide 10 and has its forward end shaped to cut and form the staple-like hinge member. Wire C is fed through a hole in a block 14, Fig. 6, to a length allowed by a stop 15. A link 32 is operated by a suitable hand, treadle, or power lever to move to the left the slide 10 and with it the slide 11, so that the forward end of the latter cuts off the length of wire and bends it about a former 27, which is then withdrawn owing to the engagement of a cam-surface 29 on the slide 10 with a roll 28 on the lever 25. The slide 10 then moves on alone to force the staple legs through the box, the legs being spread outwardly. after penetrating the box, by slots in the slide 18. The lever 28 then removes a stop 26 from the slide 18, so that the latter is moved rearwardly, allowing projections 22, Fig. 2, to clinch the staple legs. A spacer 23 provides for the necessary clearance between the wire and the box body. The forward end of the slide 11 may be shaped' to form the usual upset portions and indentation in the box body to allow clearance for the lid.

Filed: 1959-04-25
Abstract: 880,174. Photoelectric flaw detectors. BRITISH RAYON RESEARCH ASSOCIATION. May 3, 1960 [April 25, 1959], No. 14183/59. Class 40(3). In an arrangement for detecting flaws in a sheet material, particularly for knitted fabrics, comprising a stationary light-source associated with a scanning device having a reflecting or a refracting surface for directing light from the source towards the sheet material, and photo-sensitive means to detect the light as influenced by the sheet material, the scanning device is mounted for periodic progression transversely of the sheet. As shown, a beam 11 from a source 11a is focused as a beam parallel to the surface of a sheet 13 on to a scanning device 15 having a lens 15a and mirror 15b projecting a linear beam of small width on to the under surface 13a of the sheet 13. The variably reflected light is transmitted in the reverse path to a half-silvered mirror 18 associated with an apertured diaphragm 19 and a photosensitive device 14. The scanning element 15 is moved across the sheet 13 by a chain or belt 16 driven by one of the wheels 17 and carrying a second scanning device 15, which is operative when the other device is moving along its lower or inoperative path. In a modification, the scanning device 15 may be reciprocated across the under surface 13a of the sheet 13. Also, a number of simultaneously operative scanning elements associated with separate photo-sensitive detectors may be arranged obliquely across the width of a driving belt. In response to a flaw the output from the photo-sensitive member 14 may be used to stop the fabricating machine, and arrangement may be made to disable the stop device for the inoperative periods of the scanning elements, i.e. whilst passing round the curved parts of the wheels 17. The detecting beam from the scanning element 15 may pass through the sheet 11 to the photo-sensitive device, and the arrangement may be used to examine the transparency of sheets, or, with the use of appropriate filters, their colour characteristics. The width of the detecting beam reflected from the mirror 15b may be such as to cover the extent of a number of groups of threads forming a periodic or recurring pattern.
