Abstract: 1,101,629. Endless conveyers. CARLSON TOOL & MACHINE CO. 17 Aug., 1966 [22 Oct., 1965], No. 36800/66. Heading B8A. A plurality of substantially identical units 10 are connected together in longitudinal alignment to form a conveyer assembly for conveying brushes 16 past a number of manufacturing units (12a-12d) (Fig. 1, not shown) attached to the framework 18 of the respective unit. Each unit comprises a pair of endless belt conveyers 42 in opposed spaced relation, to form a vertical slot 44 between their conveying surfaces in which to convey the brushes, and staggered relative to one another in their direction of travel (see Fig. 2) to ensure continuity of conveying between the units. Guides (138a), (138b) (Fig. 16, not shown) are attached to the framework 18 adjacent the trailing and leading edges of the conveyer belts 42 respectively to guide said brushes during the transistion between units. The pairs of conveyer belts 42 may be driven individually by a motor mounted . on the respective unit or by a single motor driving a common drive shaft 46 extending longitudinally of the conveyer assembly. The motor (48) (Fig. 8, not shown) drives a pulley (50) around which extends an endless belt (54) to drive a further pulley (56) connected to a sprocket (60) which in turn drives a further sprocket (64) attached to the shaft 46. Sprockets 82 are attached to the shaft 46 at intervals corresponding to the units 10 to drive a chain 84 extending around two sprockets 86 connected through a shaft 88 to a further two sprockets 92, each corresponding to one of the pair of conveyers on the unit. The sprockets 92 each drive a vertically extending chain 94 to drive a sprocket 96 attached to a worm gear 102 in engagement with a gear 104 attached to the shaft 106 to which the drive pulley 110 of the conveyer belts is also attached. The motor (48) is mounted on rails (72a, 72b) and is movable therealong by a threaded shaft (76) to vary the tension in the chain (54) whereby through the variable speed pulley (50) the speed of the conveyers may be altered. The vertical slot 44 between the two conveyer belts 42 may be adjusted to suit different sized articles by means of a crank 176 rotating a pair of sprockets 182, 184 around which extend chains 186 which each in turn rotate a further sprocket 188 connected to a worm gear 194. The worm gear 194 engages a pinion 196 in engagement with a rack 152 attached to the mounting plate of the drive and idler pulleys of the conveyer belts. An auxiliary support 142 is arranged in the vertical slot 44 to partially support the articles being conveyed. Each conveyer belt 42 comprises an article engaging surface of relatively soft sponge like material (42a) backed by a relatively hard canvas like ply (42b) and is supported along the conveying run by a plurality of rubber covered back-up pulley 128.

Abstract: 1,115,963. Reed relays. VILLAMOS BERENDEZES ES KESZULEK MUVEK. 18 Aug., 1966 [16 Nov., 1965], No. 37125/66. Heading H1N. [Also in Division H2] A protective arrangement, e.g. for an electric motor, comprises a sealed magnetic reed contact device 30c having a control winding 35 connected in circuit with temperature responsive resistors (not shown), and a permanent magnet 31 which may be displaced against the action of biasing means 33 to close the reed contacts 45. Depending on the adjustment of a screw 34, the contacts may open or remain closed when the magnet is restored to its initial position if the winding 35 is not energized. Thus in an arrangement, Fig. 1 (not shown), using negative temperature coefficient resistors in a bridge circuit across which the winding 35 is connected, the contacts 45 are normally held closed by the magnet and are opened when the resistance of the resistors falls to unbalance the bridge to cause the winding to be energized and to oppose the magnet. In Fig. 3 (not shown) the contacts 45 are normally maintained closed by the winding 35 which is connected in series with positive temperature coefficient resistors, the contacts 45 opening when the current in the winding falls due to increase in resistance of the resistors.
