Thesuction-nozzle E is a casting comprising the parallel- lips 78 and 79 between which is the mouth opening 80; the outer surfaces of said lips being rounded so as to.
run smoothly forwardly or backwardly u on the floor, and the inner faces of said ips being straight soas to form sharp edges to serve as scrapers for loosening the dirt, the rear scraper throwing the dirt into the mouth when the machine moves forwardly and the forward scraper throwing the dirt into the mouth when the machine moves backwardly; and the neck 81 extending upwardly andbackwardly from the lips 78 and 79. A union nipple 82 is screwed into the.
neck and a union-nut 83 connects the nipple to the cap-plate, so that the dust passing 1nwardly through the mouth'will pass into the sack.
