The piston is re-turned to its starting , partly byrebounding from the tool and by the con-stant pressure admitted through ducts Cand E and port H against the annular for that part of the cylinder 59 and piston 57. For calking flues, boiler and tankseams this little tool is a marvel, and isfast being introduced into railroad shopsin this country. It is being placed on the. 55 54 53 S2
