The valve-seat has been machined away with a bor-ing bar to lit the outside of the steamchest. This is a solid casting having noports or steam passages connecting withthe former valve-scat. The illustrationalso reveals a cast iron bushing which ispassed through the outer wall of the sad-dle and into the old exhaust port whichhas been lllled up with a mixture of ce-ment and cast iron borings below theconnection point. This arrangement pro-vides the opportunity for applying a pis-ton-valve, of as large a diameter as may.

The advantage here is that or-dinary fitting work may be done in plac-ing the chest on the cylinder, and that thenecessary and accurate jointing is securedby the use of an easily applied bushing makes a steam tight job. The valve chamber when in positionhas a wrought iron band shrunk roundthe projecting end of cylinder and valvechamber, which holds the two is the principal fastening but in ad-dition, a series of bolts between the ribs,is also used to further secure the steamchest in place.
