Locomotive appliances . in a boiler the same as in an open vessel. Theproper circulation in a locomotive boiler is down to thebelly of the boiler after water leaves the check, then LOCOMOTIVE APPLIANCES. 339 down the forward leg along the side and up the backleg over the crown sheet, and forward over the top ofthe flues, striking the front head of the boiler, fromwhich point it starts to repeat the same course overagain. It is here at the front end of the boiler and atthe surface that the skimmer intercepts the impurities,settling and removing them before they have time totouch the hot flues or hot sheets. This not onlyprevents foaming, but leaves nothing in the boiler tomake scale and lessensthe accumulation in theleg of the boiler. Nothing but waterwill make steam, so keepgrease and compoundsout of the boiler. Heatis the best agencyknown for separatingsolid matter from boiler is the best con-trivance yet devised byman for heating water;as most of the solid mattercontained in the feed water comes to.

(Section Through Mud Ring.) surface when steam is up, that is the best place to remove it, It isclaimed that the surface skimmer does this before4 itstarts to make the second round with the circulation,and what little is left goes to the leg of the boiler andis removed by the mud ring device; this preventsfoaming, reduces the number of washings out, prevents incrustation and corrosion, ami is claimed tohave been found more practical than purifying thewater before entering the boiler. 340 LOCOMOTIVE APPLIANCES. It is the soft matter in the boiler that is dangerous*;the removing of that part removes the danger. This device does not interfere in the least in clean-ing out the old way, or in the use of compounds. Ifscale should form from neglecting to use the cleaner,or any other cause, compounds can be used, and whatthey dissolve and throw down the cleaner will removeat the surface and at the leg.
