Title: Improvements in automatic feed-weighing apparatus
IPC: B65B1/18
Filed: 1947-09-03
Abstract: 650,043. Filling bags. ST. REGIS PAPER CO. Sept. 3, 1947, No. 24307. Convention date, Sept. 12, 1946. [Class 94(i)] [Also in Group XVIII] In an automatic feed weigher, especially for filling valve bags, materal is directed by a deflector to a plurality of weighhoppers in turn, the weigher charges being discharged from the weigh-hoppers by belt conveyers at their bases operated in timed sequence with the deflector. A conveyer 108 delivers a continuous stream of material from a bulk supply hopper 109 to a deflector unit 91 incorporating a pivoted deflector 89 which directs the stream alternately to two weigh-hoppers 20L, 20R each associated with a separate bag filling spout 64L, 64R. The weigh- 20L, 20R each associated with a separate bage filling spout 64L, 64R. The weigh-hoppers are carried by separate weigh-beams 45L, 45R, loaded by weights 50L, 50R, and adjustable supplementary weights 51L, 51R, and each is adapted to be discharged by a belt-conveyer as 22L driven by a motor 38L. The conveyer frame and motor are mounted on the weigh hopper and the conveyer belt forms its base. Associated with each bag spout 64 is a packer unit comprising a grooved centrifugal pulley 74 engaged by a belt 71 and continuously driven by a motor 75, whereby the weighed charges delivered by the weigh hopper conveyers 22 are ejected into the bags on the spouts. The motor 75 is also adapted to impart a jigging motion to bag supporting saddles 78L, 78R. The apparatus is adapted to function continuously, the deflector 89 being turned from one position to the other by a pair of solenoids energized in turn by mercury switches as 59L associated with the two weigh beams. Switches operated by an arm on the deflector shaft simultaneously control the weigh hopper discharge conveyer motors as well as solenoids 68L, 68R adapted to release bag clamps 65L, 65R on the spouts. Thus, when a w e i g h-hopper lowers on receiving its weight of material, the corresponding mercury switch 59L or R closes and energizes the approp r i a t e deflector solenoid to divert the stream to the other weigh hopper, the discharge conveyer motor 38L or R of the filled weigh hopper being simultaneously energized to deliver the charge by way of the corresponding packer unit to the bag clamped on the e filling spout. At the same time, the motor switch also also energizes the solenoid 68L or R of the bag clamp of the hopper now being filled so as to release the previously filled bag from the spout. The bag saddles 78L, 78R are pivoted to their jigging supporting arms so that the filled bags drop away from the machine automatically. The filling rate is controlled by a gate 110 in the main supply stream and by a pivoted stop as 58L which limits the opening of a discharge flap at the out'let.from each weigh hopper. The gate and stop are adjusted simultaneously by means of a slide bar 112.

Abstract: 998,340. Trigger mechanisms. SECRETARY OF STATE FOR DEFENCE. June 4, 1964 [June 19, 1963], No. 24372/63. Heading F3C. Trigger mechanism includes a spring-actuated hammer 1 incorporating a cocking bent 8, a spring-loaded sear 2 for engaging the bent to hold the hammer in a cocked position and a firing member 3 for engaging the sear to move it, against the spring-loading 14, out of engagement with the bent to release the hammer. The sear is also spring-urged to move out of engagement with the firing member, on release of the hammer, whereupon its spring- loading returns it to a position for re-engaging the bent. In operation, a pivoted lever 29 draws the pullrod 22 rearwardly so that claws 28 on the fork 24 of the pullrod engage the sear to rotate it about pivot 15 until the hammer is released. Immediately thereafter spring 14 causes the sear to slide downwardly, pin 15 moving relatively to elongated slot 16, bringing claws 28 opposite recess 21, thus enabling sear 2 to be rotated clockwise by spring 14. The hammer when returned by the recoiling breech-block re-engages the sear and raises it to its upper position on release of the pullrod 22. In modifications the sear slides in two directions at right angles and the firing member is a pivoted member.
