Cleaning Sewers from the Street 



Many of the disagreeable features 

 of the work are being eUminated 



AXO\"EL machine whicli is desjigncd to 

 ilcan sewers from the street and thus 

 chminate much of the disagreeable 

 work in the sewer, has been put on tlie 

 market b>' a western manufacturer. Tlie 

 apparatus and its metliod of operation are 

 shown in the accompanying illustrations. 



The device consists of 

 two four-wheeled trucks 

 placed at two successive 

 manhole openings and a 

 special steel bucket pulled 

 between manholes by 

 means of a cable, one end 

 of which is attached to a 

 hand-winch on one truck 

 and the other end to a similar winch on the 

 other. The bucket is not necessarily drawn 

 from one manhole to the next, but is drawn 

 into the sewer only far enough to be lilUcl 

 with the deposit and then pulled out ot the 

 same manhole in which it was inserted. 



The expansion bucket, which is 

 used with a trolley-jack. The 

 jaws are sharpened for scraping 



lifted out of 

 cable's cutting 



This is made possible by the construction of 

 the bucket, which has two hinged scoops 

 at one end so arranged as to close up tight 

 when the reverse pull is made, and also to 

 expand the bucket when it is emptied. 

 Four guard-plates are riveted to the sides 

 of the bucket to prevent excessive wear. 

 They form a hinge for the 

 jaws. The edges of the 

 scoops are sharpened to 

 cut any roots or growths 

 that might be in the 

 sewer bollcm. 



A special feature of the 

 apparatus is the means 

 whereby the full bucket is 

 the manhole without the 

 nto the sewer or manhole 

 brickwork. This is done by means of a 

 guide-jack, consisting of a yoke with ball- 

 joint adjusting-screws at one end and a 

 wedge connection on the other end. This 

 is lowered into the manhole on chains 

 hooked to the manhole-rim, and carries a 

 pi\()ted arm with a cable pulley. When the 

 bucket is being taken out, it strikes the 

 arm, revolving it upward about 

 its pivot, so that the bucket is 

 guided free out of the scwer-tile 

 and then up the center of the 

 manhole without obstruction. 



The shari)eiH'd jaws scrajie the 

 till' thorougliK' so that e\ery par- 

 ticle of debris is rem<ned. When 

 shut the\- are so tight that noth- 

 ing in the bucket can escajJC. 



When the reverse pull is made 

 on the cable the jaws of the 

 bucket close automatically so 

 that nothinR can escape 

 except the excess water, for
