Title: Improvements relating to gripper-shuttle looms
IPC: D03D47/24
Filed: 1948-08-19
Abstract: 653,773. Gripper shuttle loom ; checking shuttles; stop motions. SULZER FRERES SOC. ANON. Aug. 19, 1948, No. 21865. Convention date, Aug. 20, 1947. [Classes 142(i), 142(ii) and 142(iii)] As a gripper shuttle 150 arrives in the receiving box 102, Fig. 7, it is stopped by brakes 69, 136, and is then pushed back to the position shown by a slide 131, whereupon a shuttle opener 85 descends to open its grippers.. A pusher 98, Fig. 10, then pushes the shuttle sideways out of the shuttle box into a passage 149, the shuttles in the passage being fed one by one (by the oscillations of a hammer 113 and a catch 124, Figs. 3 and 10), on to a conveyer belt 146 which takes them back to the picking end of the loom; the hammer 113 may be omitted, in which case the shuttles are fed through the passage by the pusher 98 only. Shuttle stop motion, Figs. 3, 4, 7. A spring-loaded feeler 48 is allowed to fall when a shuttle arrives in the box and is supported by the shuttle so that a reciprocating bar 46 slides idly through a hole in the feeler. If, however, a shuttle fails to arrive, the feeler drops far enough for a tooth 155 to engage a notch 157, thereby arresting movement of the bar; a camoperated lever 28, which actuates the bar, is thus prevented from turning about its fulcrum 29, and the fulcrum is accordingly displaced against the action of a spring 31, causing a ball 34 to push a rod 35 which, through connections 38, 40, turns a shaft 44 to stop the loom. If (owing to wrong adjustment of the brake 69) the slide 131 knocks the shuttle too far out of the box, the feeler 48 drops in time for a second notch 159 in the bar 46 to engage the tooth 155 and stop the loom. Other stop motions, Fig. 3. The brake 69 is actuated by toggle links 59 set and upset by a cam-operated lever 55; the shuttle opener 85, Fig. 7, the pusher 98, hammer 113 and catch 124, Fig. 10, are all similarly actuated by cams. If any of these. parts is obstructed, the fulcrum of the relevant operating lever such as 28, Fig. 3, is displaced, causing a ball such as 34 to turn the stop shaft 44.

Abstract: 1464101 Full-face disc brakes; other friction members M M HINE 8 May 1974 [10 May 1973 7 Sept 1973] 22361/73 and 42143/73 Heading F2E A hub drivably coupled to an epicyclic gear train is braked by applying a braking force to a rotatable component of the gear train. As shown in Fig. 1 a hub assembly for a road wheel comprises a hub 1 which is rigidly secured to a planet carrier 2, planet pinions 3, a stationary ring gear 4 and a sun wheel 5 on a half shaft 6. A stack of sintered metal brake plates 7 has alternate plates internally and externally toothed and engaged with an externally splined extension 5a of sun wheel 5 and an internally splined extension 2a of planet carrier 2 alternately. For braking, the plates are all moved towards the planet carrier by hydraulic, pneumatic or mechanical means not illustrated, so that when eventually relative rotation between the planet carrier and sun wheel ceases, the road wheel is stopped. In modifications, not illustrated, alternate brake plates are carried by the ring gear 5, and the remainder by either the sun wheel extension 5a or the planet carrier 2 or the hub 1. In further modifications, each of the three planet wheels carries plates, while the remaining plates are carried by one of the other components (including, as one example, an extension of the ring gear 4) or by the hub. In Fig. 5, plates 71 on a splined extension 3a of a planet pinion 3 are interleaved with circular plates 73 slidable axially on dowels 10 extending from a cover-plate 9 of the hub 1; actuation is by a mechanism 11. The same features are repeated for the other planet pinions. Cover-plate 9 is removable. In Fig. 3 the planet pinions 3 are indirectly locked for braking by providing each with a set of circular plates 71 interleaved with a common stack of floating plates 72 each of which is of tri-lobular shape. In general, a third brake member or set of members may be moved, for braking, into engagement with brake members or sets of members carried by any two relatively movable parts respectively. Brake plates may be dispensed with; instead, one or more components of the gear train may have surfaces covered with frictional material or be formed from a frictional material and may be displaced axially for direct frictional engagement for braking. Brake actuation may be by hydraulic cylinders supplied through ducts in the hub shaft; an axially movable sleeve rotatable with the shaft and sun-wheel having projections extending through the latter; or a cam mechanism operated by pins projecting from a sleeve which can perform limited rotational movement with respect to the shaft. The brake may be located nearer to the vehicle centre-line than is the gearing so that elements of the latter must be removed for brake servicing. The road wheel may be free running or gear driven by the vehicle engine.
