pulley shaft and retainer is provided but is not shown its construction is identical to items 8 and 24 above on both plates retainers 14 are provided to prevent legs 5 from rising beyond horizontal the body plates are connected by rods 9 which insures their relative alignment will remain constant bushing 12 is affixed to the lower plate which receives rods 9 in a sliding fashion the upper ends of the rods are fixedly attached to the upper plate at 29 helical or coil springs 10 circumferentially surround rods 9 so as to resist the approach of plate 8 to plate 13 at rest the plates are most distant from each other the pulley in plate 8 is functionally connected to the pulley in plate 13 by means of rope or cord 60 which passes through an aperture 61 in plate 13 is threaded over pulleys 36 56 26 and 46 in that order terminating at a connection where it is fixedly attached to the upper plate this connection is made to a link which is mounted around pulley shaft 24 the link is pear shaped in the preferred embodiment the shaft turns within this link and line 60 terminates at this fixed connection free end of rope 60 communicates not shown in fig1 with rope 111 shown in fig2 this rope connects at points 106 and 105 with leg retraction means 107 as shown in fig2 in actual operation the entire unit with legs 5 folded inwardly or retracted is placed inside the chimney or flue 101 to be cleaned usually this can be accomplished through the clean out door 104 which is found on most chimneys once interior to the flue with the brush above the legs 5.
