In order that the final position maj' be maintained for a certain time 

 and, on the other hand, that the original position may. easily be regained, 

 the following arrangement is provided : the balance weight / is fitted with a 

 second group of ratchet teeth h with which a pawl i engages ; this pawl is 

 linked to a part driven with a regular reciprocating motion, e. g. the compres- 

 sor-ram k. At each blow of the ram, this pawl causes the balance weight 

 disc to advance one tooth at a time up to the last of the teeth h. Then the 

 movement of the pawl i ceases to take effect, and the pawl d keeps the balance 

 weight iri the raised position, as well as during the intervals in the ratchet 

 action. 



The cycle of movements begins again only after the toothed wheel 

 a releases the pawl d in the way just described. Then the weight / falls when 

 the ram retires to the left, and the pawl i leaves the teeth h.
