Abstract: 1375323 Overrunning clutches ASPRO Inc 7 Aug 1972 [2 Dec 1971] 36824/72 Heading F2C  In a reversible overrunning clutch in which a driving member 16 is moved by meshing helical teeth 16a, 20a the latter being on a hub member 20 attached to the input member 6, to engage overrunning teeth 16b and 12a or 16a and 10a to drive an output shaft 2 through clutch members 10 and 12 respectively, splined to it on the input tending to rotate faster than the output, an annular control member 24 is provided which moves the driving member 16 towards teeth 12a or 10a depending on the direction of rotation of the input 6 and prevents it moving towards the other set of teeth (12a or 10a respectively). The member 24 is urged leftwards by a spring 26, has overrunning teeth 24a engageable with teeth 28a on a cam member 28 fixed to a stationary housing 4, and is engaged by a split holdout ring 30 which has axial projections 30b engaging slots (Figs. 7 to 15, not shown), in an inner flange of member 28. On the member 6 rotating in a first direction, with the output 2 overrunning it, the overrunning teeth 24a, 28a disengage to cause the member 24 to move to the right against spring 26, which causes the holdout ring 30 (through flange 30a), and the driving member 16 (by engagement of ring 30 and a flange 16d), to move to the right so that the projections 30b leave the slots in member 28 which allows the ring 30 to rotate slightly and hold the member 28 in the rightwards position shown by engagement of steps in the projections 30b (Fig. 14, not shown), with the sides of the slots. On reverse rotation of the input 6 the projections 30b enter the slots, the member 24 moves to the left under the action of spring 26 and the driving member 16, by engagement with a shoulder 24b of member 24 is moved, by a small extent to the left, ready to engage with teeth 10a should the output stop overrunning the input. Spring rings 18 and 34 provide drive, via friction drag, to members 16 and 24 respectively. A further embodiment is described (Figs. 16 to 21, not shown), in which input and output are coaxially spaced, the principles of operation being unchanged. The device may be used in a vehicle which has drivable front and rear axles, the front axle (connected to shaft 2) normally overrunning the rear, and only being driven if the rear wheels (the rear axle being connected to member 6) slip.

Abstract: 898,908. Making tyre bands. GOODYEAR TIRE & RUBBER CO. Nov. 7, 1960 [March 1, 1960], No. 38137/60. Class 144 (1). Bands B of tyre-ply fabric are built up to any desired exact length on an inextensible endless belt 43 which is supported around rollers 11, 12, 13 and 15 and over a roller 14, the rollers 14 and 15 being mounted a fixed distance apart on a carriage 30 which is movable relative to the other rollers 11-13 to provide the limiting positions of the rollers as shown in Fig. 4, whereby the effective length of a band B circumscribing the belt may be varied, and a second endless belt 47 supported around rollers 48, 49 being movable into and out of engagement with the belt 43 to hold the band against the belt 43. As shown, the rollers 11-13 are journalled on a frame 10 having guides 32, 33 for the carriage 30, the carriage being movable therealong by a hand screw 34 engaging a block 35 on the carriage and axially anchored at its end to a piston-rod 40 of a piston and cylinder 41, 42. The roller 11 is driven from a motor 20, and the reverse guiding of the belt 43 over the roller 14 permits maintenance of the belt tension in any adjusted position of the carriage 30. A calibrated scale 75 provides for ready positioning of the carriage according to the diameter of band desired. The carriage 30 serves also to support a band guiding roller 44. The co-operating belt 47 has its support rollers 48, 49 mounted a fixed distance apart on a member 50, the ends of which are pivotally attached respectively to a pair of arms 51, 54 which are in turn connected by an adjustable link 55. The arms 51, 54 are each pivoted intermediate their ends at 52, 56 respectively and arm 51 is acted on by a piston and cylinder 58, 59 operable to effect rotation of the arms 51, 54 about their pivots to withdraw the belt 47 to the inoperative position of Fig. 3. In so doing, a link 65 normally supporting the free end of the roller 11 is also withdrawn to permit axial withdrawal of a tyre band from the belt 43. In operation, with the carriage 30 set to the desired band length and the two belts in cooperative relation as in Fig. 1, the roller 11 being driven, a tyre ply is fed on to the belt 43, and engaged between it and the belt 47, whereupon the operator guides the free end of the ply around the roller 44 and effects a splice. Subsequent ply lengths are wound thereupon in like manner, with their splices relatively spaced apart until the desired band is formed. A stitching roller 68 carried at one end of a pivoted arm 69 is then lowered by means of a piston and cylinder 74, 73 to consolidate the band plies against the roller 11. The stitching roller 68 and belt 47 are then withdrawn, and the cylinder 42 is operated to retract the screw 34, and thereby the carriage 30, to permit removal of the band B axially of the belt 43.

Display apparatus comprises two screens, each having a grating pattern of light and dark elongated areas (Fig. 7), relative movement of the screens causing the dark bands, formed by coincidence of dark areas in one screen with light areas in the other, to move. Fig. 8 shows one screen 19 fixed in the front of a container 10 while a belt 13, formed of transparent material with parallel black lines and forming the other screen, is moved over pulleys 14,15 by a motor,a diffusing screen 18 and fluorescent tubes 11 illuminating the screens from behind. In front of the screen 19, masks or screens 20 are marked to form a stationary part of the display against a moving background of bands. By having the grating pitches on the two screens different, and having one grating at an acute angle to the other, (Fig. 7), the bands can be made to move in any direction, while the screens move normal to the lengths of one set of grating areas, (Figs. 1... 5,not shown). A grating may comprise opaque or transluscent lines on a transparent or less transluscent backing. Screens may comprise portions having differing grating orientations (Fig. 6, not shown). Screens may be coloured, and there may be more than two screens. The effect is equally evident if the screens are illuminated from the front only.
