AGRICULTURAL MACHINERY AND IMPI^KMENTS 



of Wanzleben, Germany), to design a motion (German patent No. 292442) 

 which is released by the moving parts of the press, and at the right moment, 

 by the toothed wheel. The latter does not perform the necessary work which 

 is now done by the new piece of mechanism. 



Figures 1 and 2 show the parts at two phases in the cycle of operations : 

 the toothed wheel a turns a cam b, controlling a weighted trip c which, after 



Clidching and declutching mechanism. 



Fig. I. — Clutching . phase. 



Fig. 2. — Dechitching phase. 



SO many turns of the wheel a corresponding to the size of the bale, falls and 

 thus releases the pawl d at the right moment ; this in turn sets free a balance 

 weight / furnished with ratchet teeth e, which passes from the position shown 

 in fig. I to that in fig. 2, controlled by any suitable device, e. g. the pin m 

 and the stop n. This movement is used to clutch and declutch through (say) 

 the link g.
