The tube 19 takes the place of the chamber 19 in Fig. 1, and the connecting pipes 17.and 22 have their equivalents in the said tube. The valves 18 and 23 operate the same in Fig. 3 as in Fig. 1. An adjustable stroke may be given to the bellows by shifting the position of the rods 29 and 30 along the slot shown in the ends of the walking beam 26. Of course, various. changes cduld be made in parting from the spirit of my invention.
