Filed: 1949-10-14
Abstract: 659,381. Levelling coke-oven charges. KOPPERS CO., Inc. Oct. 14, 1949, No. 26453. Convention date, Oct. 14, 1948. [Class 51(ii)] A coke oven leveller bar mounted on an electrically driven pusher machine 20 is divided into a lower portion 30 formed by spaced channel members 35 connected by cross members 36 and closed on the upper side by a flat plate 37 and an upper portion 31 forme by channel members 40 connected by cross-members 41 said upper portion being kept in contact with the lower portion by spaced brackets 42 secured thereto and lapped over the flanges of the channels 40, the compartments formed between the two portions of the bar being filled with granular material such as coke breeze or coarse coal as said bar is advanced into the coke oven and discharged therein by separately retracting the lower portion of the bar. Initially, relative horizontal movement between the two portions of the leveller bar is prevented by projections 50 on sliding blocks 45 engaging holes in the channel members 35, said sliding blocks 45 being held in the lower of two positions between blocks 46 fixed to the channel members 40, spring pressed detents in the blocks 45 engaging sockets in the blocks 46. The leveller bar is driven forward by a cable 53 actuated r.y a motor 51 and wound round a sleeve 55 being fed with granular material from the hopper 85 until a sliding door 86 is closed by a buffer 88, and at the end of its stroke the upper portion 31 of the bar is held by a plunger 76 operated from an air cylinder 75. At the same time a contact 72 driven from an air cylinder 70 strikes a projection 73 on the block 45 raising it to the upper position between the blocks 46 and releasing the projection 50, the lower portion 30 of the' bar is retracted by the cable-53 thus depositing the granular material over the coke oven charge, and the upper portion 31 is then retracted by a cable 60 wound round a motor driven sleeve which is co-axial with the sleeve 55 and may-be connected thereto or detached therefrom by a clutch. When the two leveller bar portions are again in alignment a contact 81 driven from a third air cylinder 80 restores the blocks 45 to their original position between the blocks 46 thus locking the two portions together again. Specification 630,128 is referred to.

Abstract: 385,038. Charging coke ovens. STILL, C., Recklinghausen, Westphalia, Germany.' Sept. 22, 1931, No. 26473. Convention date, Sept. 23, 1930. [Classes 51 (ii) and 55 (i).] Charges, compressing.-In a coke oven the loose charge is compressed, either in the oven chamber 1 itself or in a charging box therefor, by screwing worms 23 once or more into and out of the charge, the worms being so formed that the greater part of the movement necessary for closely packing the charge takes place laterally. As shown, the worms 23 are carried by vertical shafts 17, which extend upwardly through the charging holes 5 and the hoppers 8 mounted on the charging truck 7, and are suspended from a vertically movable counterweighted girder 12 guided by rollers 13 in a framework 10. The shafts 17 are driven through bevel gearing 18, 19 from a common shaft 21 carrying a driving pinion 22 and mounted in bearings 20 on the girder 12. Each worm 23 is of greatest diameter at its central portion, and the thread is of triangular cross section with the under surface inclined upwardly towards the shaft 17. In operation, when the oven has been charged from the hoppers 8 to form conical piles 25 as shown, the girder 12 is gradually lowered and the shafts 17 set in operation, the amount of compression produced being determined by the size of the counterweights attached to the wires 14. When the worms reach the bottom of the oven chamber, their direction of rotation is reversed and they screw themselves upwardly out of the charge ; the effective pressure on the charge, as determined by the counterweights, is preferably different during this upward movement. Mechanical means for pressing the worms downwardly can be employed instead of counter weights. In a modified method of working, the worms are set initially in their lowermost positions, the compression being effected during a single upward movement. The hoppers 8 are constructed to provide a continuous supply of fuel during operation of the compressing worms, bridging being prevented by stirring arms 24 mounted on the shafts 17. The latter may be so constructed, e.g. by the provision of a supporting ring 16 of wavy or sinuous form, that they are vibrated vertically during rotation.

Abstract: 629,447. Suspension devices. VICKERS-ARMSTRONGS, Lid., and FIRMAN, R. A. Oct. 3, 1947, No. 26668. [Classes 44 and 89 (ii)] In a hook device for the suspension and release of loads, of the type disclosed in Specification 572,809, the hook members 62, 63 are held together by a roller 66 engaged between surfaces 621, 631 on the jaws. The roller is retained in position by a mechanism comprising a braced linkage which is caused to collapse by means of a blow from an electrically operated rotary actuator 73. To enable the mechanism to withstand shocks, a shock absorbing member is interposed between the rotary actuator and the linkage arm 71. The shock absorbing member may comprise a pad of felt 28 as in the form of Fig. 2 in which-the linkage is shown in the collapsed position the pad normally resting on the link 71 under the influence of the spring 26 to retain the linkage in the braced position. Energisation of the coil 76 turns the actuator against the action of the spring so that the lower face 25 delivers a blow under the link 71 to cause the linkage to collapse. In another form, shown in Fig. 3 with the linkage in the braced position, the shock absorber comprises a spring wire 29 secured to the rotary actuator and having a bridge piece bearing on the knuckle joint of the links 71, 70. The links may be provided with a V notch in which the bridge piece sits. As the actuator turns to release the load, the bridge piece of the wire is lifted to free the links before the surface 25 delivers a blow to the link 71 to cause the linkage to collapse.
