Abstract: 374,067. Mechanical stokers. AMERICAN ENGINEERING CO., Aramingo Avenue, Philadelphia, U.S.A. Feb. 24, 1931. No. 5799. Convention date, Jan. 7, [Class 51 (i).] In underfeed stokers comprising interspersed retorts and tuyeres the side walls of the retorts are sealed by packing inserted in grooves formed in parts between which air is liable to leak into the retorts, so as to prevent admission of combustion air to the fuel bed except through the tuyeres. The side walls of the retorts 1 comprises plates 4, 5, 6 and extension plates 15 supported on beams 3 and act also as supports for the tuyere elements 6a which bridge the tops of the tuyere chambers 2. The floor of each retort chamber comprises a top coal feeding plate 7 and a series of dead-plates 8 .. 12 in the spaces between which slide pushers 13 and a bottom pusher 14. The upper ends of the retorts are provided with side-plates 15 extending between the top side wall plate 4 and the front wall 17 containing the feed opening 18, the joint between the plates 4, 16 being sealed by packing in a groove 30. The joints between the plates 5 are sealed by packing strips 45, and gaskets 46, Fig. 4, held in place by bolts 36a and a backing member 47. Longitudinal grooves 49, 50 in the plates 4, 5, 6 contain packing to seal the joints between these plates and the beams 3. The extension plates 15, Fig. 24, are provided in the upper, lower and inclined edges with a continuous groove 54 co-operating with corresponding grooves in the adjacent plates 4, 5, 15 to contain packing. The top plate 7 over which the coal is fed has side flanges 62, Figs. 27 and 28, which lie closely against the side walls of the retort formed by the plates 4, 16, and inwardly inclined surfaces 61 with spaced vertical recesses 63 for the reception of packing. At its end adjacent the front wall 17 the plate 7 has a packing groove 64. The dead-plates 8, 9, Fig. 31, whose side edges abut the opposite side walls of the retort are provided. with continuous corner grooves 66 for the reception of packing. Fig. 33 shows the dead-plate 10 which has a wider rear portion 71 adapted to extend between the sides of adjacent beams 3 and a projecting portion 75 extending between the side wall plates 5. Packing grooves 72 seal the wide portion while side flanges.76 and inwardly inclined surfaces with recesses 78 form pockets for sealing the projecting portion. Each pusher 13, 14 is provided at both sides with sealing means comprising a flexible plate or strip 81, Fig. 43, mounted in inclined recesses 82 in the sides of the pushers. Recesses 85, Fig. 1, provided in the under sides of the deadplates 8, 9, 10 contain a transverse sealing rod 86 bearing on the upper surface of the underlying pusher. Transverse serrations 88 on the under side of each pusher seal the joints between the bottoms of the pushers and the deadplates. Specification 367,866 is referred to.

Abstract: 881,605. Pipe couplings. AEROQUIP A. G. Feb. 23, 1960 [April 8, 1959], No. 6347/60. Class 99(1). A coupling comprises first and second follow coupling members 10, 54 and means for locking the members in communicating relation, an adaptor 76 having a universal connection to the member 54 and serving to enable a conduit to be coupled to the member, and means operably connecting the adaptor with the locking means so that pivoting of the adaptor relatively to the member 54 will release the locking means. As shown, the part 10 includes a spring-loaded valve 24 normally biased on to a seat 22 and having air bleed holes 32 communicating with a passage 16, and a spring-loaded valve 42 provided with ports 40 and an air bleed passage to equalize the pressure on opposite sides of the valve. The part 54 comprises a body 56 into which is screwed the swivel adaptor 76 and mounting a valve 60 slidable on the body and having radial ports 66 adapted to be closed by a spring-biased sleeve 68, the latter sealingly engaging a conical surface on the valve. A member 92 secured to the body is formed with a number of circumferentially spaced holes 98 receiving balls 104 which are retracted into the holes by a spring-loaded ring 102. A locking sleeve 112 has affixed thereto a member 120 provided with a cam groove 122 for reception of the balls ; a nut 114 screwed into the sleeve has an opening 116 providing clearance for an actuator sleeve 82 formed with a cam ridge 88. A rubber shock absorber 128 on the sleeve 112 has a hinged dust cap 130 closing the end of the coupling member 54 when the latter is not in use. In coupling the members 10, 54 together, the members are axially moved into engagement so that the end of the ring 102 abuts the face 50 of the ridge 47 on the member 10 and the shoulder 74 contacts the valve retainer 38 and the ports 66 of the valve 60 are opened, the balls 104 then passing over the ridge 47 and moved radially inwards by the cam groove 122 and behind the ridge ; the surface 118 of the nut 114 is brought into contact with the ridge 88. The ports 40, 66 being fully open allows pressurized air to pass through the coupling to open the valve 24. Swivelling movement of the adaptor 76 due to a transverse pull thereon causes the ridge 88 to act as a lever on the surface 118 to withdraw the sleeve 112 and so that the balls 104 are forced outwardly from engagement with the ridge 47.
