\ uh l at the uwcyiug the it into and vitiimHl-s'. The dis charge into the supcrlwatcr is in front. of hullle 1(3 and tho passing along the longitudinal length of the U-tubcs are caused to How d wnwardly between hatlles 1G and 17 among the water lube-s 15. It will thus be noted that the hot gases: after passing from the superheater are utilized to heat the water tubes. The baffle 16 is provided with extensions 16 at the upper end thereof 55 and serve to deflect the furnace gases, coming through the pass-a cs 24, among the supcrheat-er elements. s shown, the superhcater elements adjacent the side walls of the boiler setting pass rca'i'wardly through the deflectors. It will therefore be seen that the gases coming through the passages 24 will be properly disseminated tlroughout the, super-heater and especially at that p0rtion which is remote fsom the headers thereof.

The headers of tho superhcater are shown at 526 uud 27- To the header are conilt ili'fl the tubes 28, which .:onvoy the steam from th upper part of the drums, or from 39 tho upper part of tho water log to thosupec' heater: The harder is provided in the and thereof with an outlcl .259 extcnding through either sirlo of the hoiler fitting. It is obvious that the outlets can bc provided upon both sidcs of said setting. Such a consiructiou not only reduces the number of joints ncvcssary to build up the ordinary connections, but also stcarlies and lowers the steam pipc. (.onscquoutly & holler of a larger capacity can be used with a low ccillug.

It will bc observed from the above description that the furnace gases due to the vertical baffling and the arrangementof the superheater and associated parts, pass from the furnace through the water tubes 15, over the bafile 16, downwardly through the water tubes under the ballle 17, and again umvardly through the water tubes to the smoke stack. Part of the furnace gases puss directly to the superheatcr, and after having the same pass downwardly between the baffles among the water tubes and from this point follow the course of the gases which pass from the furnace directly into the water tubes. Hence the hot gases which pass directly to the superheater from the furnace sweep downwardly among the boiler tubes and aid in heating the said tubes.

What I claim is:

1. The combination with a boiler setting and furnace, and a water tube boiler having its water tubes arranged in the path of the furnace gases flowing through said setting and having one or more drums above said tubes, of a superheater above said water tubes and exposed to the open space between said tubes and the drums, and flues or conduits in the side walls of the setting extending from the furnace and discharging hot gases therefrom upon the superheater, substantially as described.

2. The combination of a'boiler setting and furnace, a drum supported in said setting, a superheater located below said drum, batlle located below said superheater, bypasses for hot furnace gases in the sides of the boiler setting, and extensions or deflectors on said baffle to disseminate the hot gases flowing through the by-passes throughout the super-heater elements.

3. The combination with a boiler setting and furnace, a drum supported in said setting,' inclined water tubes located between the furnace and drum, front and rear battles for'the water tubes to deflect the hot 'gases upwardly and downwardly among said tubes, a superheater located between the water tubes and the drum, by-passes in the hot gases toward the center of the boiler 7 setting.

' 4. The combination of a boiler setting, one or more drums supported in said setting, water tubes substantially below said drums and arranged longitudinally thereto, a superheater having tubes between the drums and the said water tubes, said superheater tubesbeing substantially parallel to said drums, inlet and outlet headers for said superheater, conduits adapted 'to supply hotgases directly from the furnace to said superheater, battles to deflect the aforesaid .gases among the superheater tubes, means to convey steam from the drums to the aforesaid inlet header, and means to convey the steam from the outlet header through the'side of the boiler setting.

In testimony whereof I afiix my signature in the presence of two subscribing witnesses.
