Filed: 1950-06-22
Abstract: 691,928. Endless conveyers. HART, SON PEARD & CO., Ltd., and GOPSILL BROWN TRADING CO., Ltd. June 13, 1951. [June 22, 1950] No. 15578/50. Class 78 (i). An endless belt or chain elevator of the kind having article engaging means on the belt or chain for transporting articles upwardly within a body portion has pivotally attached to said body portion side members forming extensions of the body portion which extend on either side thereof and parallel thereto, wherein the side members are adjustable from a position in which they project outwardly parallel to the base of the body to a position in which they are disposed above the body so as to form therewith a closed trough. As shown, the elevator body portion consists of a casing 14, for the return run of an endless chain 27 carrying scrapers 31, which casing is composed of sections joined by flanges 34 at their ends, a series of plates 15 bolted over the open tops of the sections 14 and forming a floor for the upper run of the scrapers 31, and a series of pairs of side members 16 hinged to brackets 33 on the sections 14. When side members 16 are pivoted upwardly, Fig. 6, their outer portions abut to form a closed trough and are secured together by a link 40 on one member 16 engaging a headed pin 41 on the opposite member. Plates 9 secure the series of members 16 together adjacent the joints in casing 14 and a bracket 35 on each plate 9 supports a pivoted link 36 the other end of which has a pin engaging a guide slot 37 in a bracket 38 secured in the casing joint so that by means of recesses 39 in each slot 37 the members 16 may be held in one or more inclined positions. The members 16 may be moved to a horizontal position by allowing the pin to fall to the bottom of each slot 37, additional support for the members being provided by the top of each bracket 38. Except when in the closed trough position the links 40 may be used to connect together the outer portions of successive members 16 as shown, Fig. 1. Casing 14 is pivotally mounted on the axis of its lower sprocket to a chassis 11, the lower sprocket being driven by a motor on the chassis, and pivotal movement is effected by a pair of flanged rollers 17 on the ends of links 18 pivoted to the chassis, and a cable and pulley system 21, 22, 23 operated by a winch 24 for moving the roller along the under side of casing 14. Material or articles may be fed to the elevator by a feed shoot 43 pivoted on the axis of a shaft 47 to plates upstanding from casing 14. A further scraper chain 44 traverses the bottom of shoot 43 and is driven through shaft 47 from the shaft of the lower elevator sprocket. Shoots and hoppers. Fig. 6. At the upper end of the elevator material may be discharged into a shoot 52 the lower end of which comprises a T section ring 54 on which a second shoot 55 may be clamped in a number of rotational positions. Pivoted on a.horizontal axis to shoot 55 is a telescopic shoot 57, the two portions 58, 59 of which are slidably connected by cooperating roll edges, (not shown).

Abstract: 763,226. Electric measuring systems. SHORT BROS. & HARLAND, Ltd. May 25, 1955 [May 27, 1954], No. 15699/54. Class 40 (1).  A piezo-electric bimorph 10 is clamped at one end 11 and used as a cantilever beam to measure vertical acceleration, the deflection at the free end being determined by strain gauges 12, 13 in a bridge circuit ABCD whose unbalance voltage is fed through an amplifier 15 and applied to the prepared surfaces of the bimorph by leads 16, 17 to reduce the deflection of the beam to substantially zero. The voltage applied to the bimorph is proportional to the suppressed deflection and therefore proportional to the acceleration. The strain gauges 12, 13 may be replaced by a differential capacitor.
