Abstract: 1,107,230. Silo top unloader. BUTLER MANUFACTURING CO. 20 Dec., 1966, No. 56982/66. Heading B8E. A silage handling apparatus for loading and unloading a silo comprises a sweep arm auger in engagement with the top of the silage and a central channel former to make and maintain a central channel for the discharge of the silage. A pair of augers 74 are suspended by cables for heightwise adjustment in the silo and for rotation therein upon a drive ring 64 in a conventional manner. The augers are mounted in a framework 24 comprising rods 26 slidable in boxes 28 fixed at the centre of the silo by a suspension stem 42 so that the auger can be moved radially inwards from the discharging position shown to a loading position, manually or as by a motor 150 acting on control arms 164 as through a crank mechanism. The framework is rotated within the silo by a motor 58 and the augers are reversibly driven by a motor 98. A hopper 112 is mounted on the framework 24 above the inner ends of the augers and has channel former 122 provided with cutters 148 depending from it below the augers. To load the silo the augers are withdrawn radially inwards a set distance and are rotated to feed silage outwards as it is fed to them from the hopper 112. As the silage builds up at the periphery of the silo it contacts a pressure switch 176 which starts the motor 58 to rotate the framework to the next loading position. During loading the former 122 makes a central channel in the silage. To unload with the augers in the position shown they are rotated to feed the silage towards the former 122 through which, and the formed channel, it falls for discharge, from the bottom. During discharge the framework is rotated within the silo and as the former is lowered it maintains the central channel with the aid of its cutters 148. In a modification a winch drum and cable are used to position the framework. In each construction a lid 134 is provided to close the former during loading and in each case the movement of the framework to its unloading position is designed to open the lid.

Abstract: 1,207,847. Container closures. M. B. STULL. 19 Dec., 1967 [24 Jan., 1967], No. 57687/67. Heading B8T. A dispensing closure comprises an upright tubular plastics body 10 adapted to be carried on a container by a base portion 12, the body having a closure pin 18 extending from a diametric bridge 16, and a plastics screw cap 20 axially movable on the body. Threads 22, 24 control the axial movement whilst a helical track 28 and a follower 30 connected to the cap, prevent backlash between the threads. The cap has an orifice 42 at the top of a tubular extension 44, on the inner surface of which are grooves 46 providing a helical path for the flow of material from the container to which the cap is fitted. As the cap is unscrewed the path becomes progressively wider. Positive stops for the raised and lowered positions of the cap are provided, namely, the lug 30 engaging surfaces 34 and 36 respectively and lug 38 engaging a shoulder 40 and an axial bead 26 respectively. The bead 26 joins adjacent upper portions of the thread 24 to prevent product from flowing between the threads and contaminating them. A lug 52 on the outside of the cap is an indicator to show the degree of opening of the cap; a lug 53 acts as a stop at the open and closed positions. An alternative embodiment, Fig. 4 (not shown) attains a smaller external diameter by moving the helical track and follower to the top of the tubular body. This particular embodiment only gives 180 degrees rotation but can be modified to give 360 degrees of rotation, as in Fig. 7 (not shown). The Specification includes a reference to Specification 1,184,239.
