of the valve connection from the center of hnk to center of rock shaft. 

 The hnk is io% inches center to center of knuckle joints, the hangers 15% 

 inches, and the lifting arms 7)4 inches long. The center of tumbling 

 shaft is iQjo inches above the center of engine, and directly over the center 

 of link, which is suspended in the center both ways. The lap is %, and 

 the eccentric lead % inch, hence the valve lead at full throw is }§ inch. 

 The exhaust when the engine is on the point of taking steam, has Ys inch 

 lead or clearance. The valve has 4.% inch throw at full stroke, and opens 

 % inch when cutting oflf at half stroke. The steam ports are 13 x '^(e inch, 

 and the exhaust 13 x 2 '^4 inches. 



The dome is in the middle of the boiler, and the dry pipe is secured to 

 the steam pipe by a strap passing through lugs on its sides, and under the 

 steam pipe. This pipe has a cone joint in the flue sheet. The branch 

 pipes are secured to the T piece by flanges and bolts as of old. 



The pump is of the modern sort, viz. a flat faced cup valve in a cage. 

 The check valve is in the center of the front sheet, and consists of a valve 

 box, elbow pipe and flange cast together. The valve seat and another 

 elbow holding a packing box for the copper pipe, are secured to the first 

 casting, by 3 bolts. 



The cab is rather showy, and quite substantial. The running board 

 extends only over the top of the wheel guards. 



Moore & Richardson make their own tire, and find it to be a reliable 

 article, though it lacks the finish of the great American tire. They also 

 make all their forgings, employing for that purpose a Nasmyth hammer. 

 They do not use nor approve of the use of scrap, for railroad forgings. 

 Experience has taught them that it cannot be relied upon, however care- 

 fully made. They are very particular in their forging, and avoid welds 

 as much as possible. The shapes for pedestals are made from a single bar 



A very extensive steamboat business is carried on at this establishment, 

 which is one of the oldest in the West. The boilers, as before observed, 

 are of excellent quality and shape. On the whole, the work will compare 

 favorably in point of strength with general locomotive work of the first class.
