Title: Improvements in friction brakes
IPC: F16D65/14
Filed: 1943-06-22
Abstract: 573,242. Brakes. THORNTON, A. A. (Warner Electric Brake Manufacturing Co.). June 22, 1943, No. 10096. [Class 103 (i)] Brake mechanism comprises a main brake of the internal expanding type that is applied by the braking torque of an auxiliary brake of the same type applied in turn by an electromagnetically-applied disc brake, the main and auxiliary brake shoes being applied to axially spaced parts of a common drum which contains also the disc brake. The main brake comprises a pair of shoes 15, the ends 28 of which are normally held by springs 30 against arms 25 on an anchor member 18 bolted to the fixed closure plate 20 of the drum 11 carried by a vehicle wheel 9. Lateral movement of the shoes is prevented by lugs 21 thereon extending through brackets 22 on the member 18. The shoes are expanded by levers 73 pivoted at 74 to the anchor arms 25 and engaging by pins 78, brackets 29 on the shoes. The levers are operated by pins 77 on a member 40 rotatable on an extension 42 of the anchor member 18 and which carries arms 54 against the ends 54' of which the ends of the shoes 48 of the auxiliary brake are normally held by springs 58. The shoes 48 are applied by levers 60 pivoted at 62 to the arms 54 and engaging brackets 57 on the-shoes, by pins 66. The levers 60 are operated by pins 64 on a magnet ring 33 rotatably mounted on the member 40 and against which is normally lightly pressed an armature ring 34, by tangential plate springs 43 connecting the ring 34 to the drum 11. Thus when the winding of the ring 33 is energized the ring is turned by the armature 34 and applies the shoes 48 to the drum and the torque exerted in the shoes by the drum is transmitted by the member 40 to the levers 73 to apply the main shoes 15. The shoes of each pair anchor at diametricallyopposite ends when applied and are thus both self-energizing. The relative thickness and width of the linings of the two pairs of shoes is so arranged in relation to the relative pressure applied to them as to ensure that they wear down equally. The ring 33 is returned by springs 70 connected to it and the member 40 which is returned by springs 81.

Title: Improvements in epicyclic gears
IPC: F16H3/54
Filed: 1930-04-02
Abstract: 352,024. Variable-speed and reversing gearing. ROYCE, SIR F. H., Nightingale Road, Derby. April 2, 1930, No. 10432. [Class 80 (ii).] In motor vehicles, &c., a variable-speed gear, preferably of epicyclic type, is employed in series with an epicyclic gear giving either direct forward or reduced reverse drive, the driving-shaft of the reversing gear being clutchable either directly to the engine-driven shaft or to the driven shaft of the variable-speed gear. The engine-driven shaft b drives a hollow shaft d through a speed-gear e, for example of epicyclic type in which is not possible or desirable to provide a reverse drive. The shafts b, d carry clutch teeth b<1>, d<1> alternatively engageable by teeth f<2> on a sliding clutch sleeve f splined to a sun-wheel g, which drives the shaft c either directly by teeth c<4> on the drum c<3> or reversely through planet wheels h<3> when the planet-carrier h is braked and the clutch sleeve f is moved to the right. Thus the shaft c may receive each of the drives of the shafts b, d at full speed forwardly or at reduced speed reversely. According to the Provisional Specification, a coupling of the type in which the clutch members are held apart until their speeds of rotation are approximately equal may be incorporated in or with any one or more of the clutches.

Abstract: 436,569. Objectives for colour projection. VALENTIN, A., 11<bis>, Rue du Lunain, and BASSANI, L., 288, Rue de Vangirard, both in Paris. April 4, 1935, No. 10502. Convention date, April 12, 1934. [Class 97 (i)] A multiple objective for three-colour projection, particularly from kinematograph film having all the colour record images in a single normal image space, comprises a mount containing three separate objectives of which one is only capable of axial displacement for focusing, while each of the others, in addition to being axially movable, can also be displaced in any direction at right-angles to its axis to obtain proper registration of the projected images. The separate objectives 16, 17, 18 are carried in mounts 24, 30 within a barrel 15 which fits into the objective tube of an ordinary projector, the mounts being provided with lugs 23, 31 slidably mounted on rods 21, 22, 35, 36 extending parallel to the axis of the barrel. The rods 21, 22 are mounted in collars 19, 20 formed on the inner surface of the barrel and the lug 23 is internally threaded to receive a screw 26 which is prevented from moving axially by a shoulder 27 engaging in the end washer 28. The screw has a squared end 29 and can be rotated from outside the casing for focusing the lens 18. The rods 35, 36 carrying the mounts 30 for the lenses 16, 17, are mounted in rings 37, 38 the diameter of which is less than the internal diameter of the barrel 15, these rings having vertical slots 39 in which engage projections 40 carried by rings 41, 42 of the same diameter as the rings 37, 38. The rings 41, 42 have horizontal slots 43 engaged by projections 44 carried by the collars 19, 20. The mounts can thus be adjusted in any direction at right-angles to the lens axes, the adjustment of the rings 37, 38 relatively to the rings 41, 42 being effected by a rod 45 bearing in the end washers 28, 57 and passing through clearance apertures 46 in the rings 41, 42. The rings 37, 38 are formed with apertures 48 engaged by an eccentric part of the rod so that rotation of the rod causes displacement of the rings. The rings 41, 42, can similarly be displaced relatively to the casing by a rod 50, the rods 45, 50 having squared ends by which they can be rotated from outside the casing. The lenses 16, 17 are axially displaceable for focusing by screws 32 engaging the lugs 31. The rings 37 &c. are held between the collars 19, 20 and washers 28, 57, the latter being secured by nuts 59, 60. To enable the barrel 15 to be secured within the tube of the projector a member is provided which can be moved radially outwards from the barrel by means of an eccentrically mounted rod so as to press against the inner surface of the tube.

Apparatus for grinding or polishing simultaneously both faces of a glass ribbon moving between rollers 21, 35, Fig. 1, in which the upper and lower element 2, 1 of a surfacing unit are mounted on supports 4, 3 movable transversely of the sheet, has the upper rollers 35 carried by the upper support 4 and the lower rollers 21 carried by the lower support 3. By this means the rollers and their driving gear may be withdrawn from their operative positions for servicing without interrupting the continuous sheet-making process; the upper and lower supports of a pair of surfacing elements may be so displaced either together or separately. Fig. 2 shows the mechanism for lifting the bearing 33 of one of the upper roller shafts 34. A motordriven shaft 28 lifts a member 23 through a rack- and-pinion 26, 27 which raises, through a spring 31, the sliding rod 30 to which the bearing 33 is secured. In this embodiment only the lower rollers are driven, the function of the upper rollers being to bear on the glass under their own weight to provide adhesion for the lower, driving rollers, this being adjustable by extent which the spring 31 is compressed before the full weight is taken prior to lifting. Further, only one pair of rollers, preferably the leading ones, may be used with each pair of surfacing units. Fig. 5 shows an embodiment in which upper and lower rollers are driven and casings 53, 54 carrying their bearings and driving gear are each movable away from or towards the glass sheet by pairs of jacks 49, 50 which may lift the rollers sufficiently clear of the surface to allow the passage between them of the surfacing elements, these being mounted on supports 45, 46 forming part of a C-shaped frame capable of movement as a whole transversely of the ribbon on a plinth 41. The ribbon is supported in the gap between working surfacing units by known means.
