Abstract: 307,999. Pritchard, R. L. Jan. 4, 1928. Breaking and scutching apparatus; rippling-apparatus.-In a machine for separating fibres from bast plants in the manner described in Specification 105,094 the material is arranged on an intermittently moved belt 2, and passed to rollers 12, 13, which break the seed bolls, the upper one being free to move vertically and heavier than the lower one. A bar 14, carried by levers 19 and. capable of being raised in guides 16, is provided with pins 15 which when lifted penetrate between the stalks. The material is gripped by groups A, A<1> of pairs of finely fluted rollers, the upper ones being fixed, and the lower ones in resiliently supported bearings. These rollers draw the material through the pins 15 to remove the seeds and align the stalks. The material is then passed to zones B - - E of rollers, each comprising a pair of smooth rollers, of which the upper one is resiliently mounted, and a number of rollers 22 provided with ribs and channels as described in Specification 105,094. These rollers are mounted in fixed bearings and are arranged in staggered formation, each.lower roller meshing with two upper rollers. Rollers 23 are mounted in front of and behind the first and the last lower rollers to prevent sagging of the material. In order to remove the remaining woody material the stalks are passed to a pair of smooth rollers d, d<1>, the upper one of which is resiliently mounted, and to pairs of rollers a, b, the lower ones being smooth and the upper ones having lines of pins 25. The material passes finally to pairs of finely fluted rollers 26, the lower ones being resiliently mounted, and to delivery rollers 28. When the stalks are gripped by the rollers 26 the direction of rotation of the rollers a, b is reversed. The lower rollers a may also carry pins. When the material treated has been previously threshed, it is necessary to provide means to align the stalks, and the feed belt 2, Fig. 8, may move continuously. The means for aligning the stalks comprises a series of pairs of rollers 30 carrying lines of pins 31, the pins on one roller being interspaced as regards the pins on adjacent rollers. The pairs of rollers move at progressively increasing speeds. The rollers 13 and the groups A, A<1> are driven by a chain from the roller 4 carrying the feed belt. The same chain also drives the first of the fluted rollers in the zone B, the remaining rollers in the zones being driven by a train of gears from this roller. The upper rollers d, 28 are carried by spring controlled levers, the frame being slotted to allow the necessary movement. The reversal of the rotation of the rollers a, b is secured by a lever carrying a group of gears, which can be moved to drive either direct or by interposing an idle gear.

Abstract: 1,208,012. Conveyer systems. LOCKERBIE & WILKINSON (TIPTON) Ltd. 2 Jan., 1968 [4 Jan., 1967], No. 511/67. Heading B7L. A semi-automatic switch for an overhead trackway for connecting three track elements 10, 11 and 12, Fig. 1, comprises a straight track-connecting element 22 and a curved trackconnecting element 23, Fig. 4, the elements 22, 23 being acted upon by a movable weight 32 so that in a first position of the weight shown in Fig. 1 the element 22 is biased to an operative position connecting the track elements 10, 11 while in a second position of the weight the curved element 23 is biased to an operative position connecting the track element 12 with the track element 10 or, with the element 11, as an alternative. The invention is characterized in that the curved element 23 is pivoted at 40 to the track element 12 and the straight element 22 is movable bodily in directions perpendicular to its length. Both elements 22, 23 are carried by a rotatable shaft 25, the element 22 by an arm 24 and the element 23 through a linkage 36, 37, 38 and 39. The weight 32 is rotatable on one end of the shaft 25 which is mounted in brackets 27 on a plate 28 carried by members 17, 18 of a triangular frame 16, 17, 18 carried by hangers 13, 14, 15. An abutment 33 on the weight is engageable with either an abutment 31 or 30 on the shaft, according to the position selected for the weight by a pull handle 35. In the position shown in Fig. 4 if a load carrying roller hanger moves along the track 11 towards the switch, it operates a pivotal lever 44 adjustably connected by a contact screw with an arm on the shaft 25 to cause the element 22 to assume its operative position against the bias of the weight. Similarly in the position shown in Fig. 1 if a load carrying roller hanger moves along the track element 12 it rides up the element 23 and causes it to move to its operative position against the bias of the differently positioned weight 32.
