Abstract
403,216. Furnace grates. SCHENK, E. M. F., 5, Missundestrasse, Altona, Elbe, Germany. Nov. 22, 1932, No. 32990. [Class 51 (i).] In a travelling grate formed with relatively movable overlapping scale-like members, the upper run of the grate moves from the rear to the front and the overlapping members are oscillated so as to impart to the fuel a stepby-step movement from the front to the rear. In one form Figs. 1, 2, 3 and 10, the grate comprises overlapping pusher members 5, 6 pivoted through links 9 to shafts 8 extending between the links 7 of inner and outer chains at each side of the grate. Alternate members 5 are connected through links 20 to rocker arms 10 each mounted on the respective shaft 8 and formed with a finger 14, a toothed segment 15 and keyed to a cam 12. The other alternate members 6 are similarly connected to arms 11 each formed with a finger 17, and nose 18 and keyed to a toothed segment 13. The relative position of the arms is such that cams 12 and noses 18 are in the same plane and that the toothed segments 13 and 15 are in the same plane and, in the upper run of the grate, interengage so that if one member 5 moves forwardly the co-operating member 6 moves rearwardly. As the co-operating members pass over the front driving sprocket drum 26 the distance between shafts 8 increases and the toothed segments disengage. At the same time the fingers 17 are engaged by abutments 28 on the drum and fingers 14 by arms 27 arranged to rotate at one and a half times the speed of the drum, by which engagements the cam 12 is moved over the nose 12 to lock the arms 10 and 11. The lower run of the grate is supported by rollers so that the locked fingers 14 and 17 of the lower run engage and move the free fingers of the upper run, which movement reciprocates the grate members 5 and 6 as shown more particularly in Figs. 1-3. Unlocking of the arms is effected by engagement of the fingers 14 between pairs of lugs 30, 31 on the rear drum 29. The distance between the upper and lower runs of the grate is increased from front to rear so that the distance of reciprocation of the grate members and consequently the rate of travel of the fuel is a maximum at the front of the grate and tends towards zero at the rear. Some of the grate members are formed as pans 62, Fig. 5a, adapted to collect ash and convey it to the front of the grate for disposal. In a modified form, Fig. 13, grate chains 34 carry reciprocating and relatively stationary members 33, 32 arranged alternately. From the reciprocating members depend arms 38 adapted to be engaged and actuated by a control chain 39 driven intermittently. The height of the shaft carrying the rear control chain supporting sprocket is adjustable in order to vary the distance between the chains in the upper run and consequently to vary the movement of members 33 and the rate of movement of the fuel from the front to the rear.
