The mechanism which is particularlyillus trated in F igs..3 and 4:, and detailed in Figs; 5 to 14, inclusive, is provided to automatically obtain at regular, but not too frequent intervals, a rocking of shaft D. Brieflystated. this mechanism consists of the reciprocating head I, having hook I rigidly attached thereto, rotating crank I shaft J, connection K extending from the crank j on shaft J to head I, link L, hook L pivotally. mounted on link L, lever M,
. cam N on shaft n, and ratchet wheel N. also on said shaft 91, dog or pawl O,bell crank P, and the connections to said partswhich The head I moves, when operated, in guide 2', and said guide issecured to the front of. the boiler. Shaft J is mounted in bearings J, and is actuated to continuously rotate by driving shaft J, which is provided with a gear wheel 3'" intermeshing with gear wheel 7" on said shaft J. The connection K moves up and down, (at the lower end thereof), once to each revolution of crank shaft J, and moves head I therewith. The cam wheel N is rigidly securedon shaft 'n, or at least to rotate therewith, and said shaft is moved with a step-by step movement, by dog or pawl O, which engages with the ratchet teeth of wheel. Said dog or pawl O ispivotallymounted on bell crank P, and said bell crank is actuated by pin ;0 on wheel 7'".
