VERTICAL. WATER-TUBE BOILER.

Application filed May 8,

To'aZZ whom it ma concern:

.Be it known that I, GLENvrLLn J. G. LAGEY, a subject of the King of Great Britain, and a citizen of the Dominion of Canada, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Vertical W aterTube Boilers, of which the following is a specification. g I 1 This invention relates to improvements in vertical water tube boilers, that might properly be called amodified vertical water tube boiler. A v

The objects of the invention arei First, to provide an improved construc tion of water tube boiler in which the heat units developedin the firebox or furnace will be more effectively utilized.

Second, to providean improved construck tion and arrangement'of water tubes in a water tube boiler.

Qbjects pertaining to details and economice of construction and operation will definitely appear fromthe detailed description tofollow. p

I accomplish the objects of my invention bythe devices and means described in the following specification. The invention is clearly defined and pointed out in the claims. A-structure which isa preferred embodiment of my invention is fully illustrated in the accompanying drawing, forming apart of this application, in which; i

Fig. I is a detail central sectional elevav tion view takenon line 1-1 of Figs. II and III, the boiler'and tube portions being shown in full lines and the position of certain parts being indicated by dotted lines, 'thecasing and partition walls andfootings being in section. p p

Fig. II is an enlarged plan view of the boiler andtube parts appearing in Fig. I, the casing and footings being omitted. a Fig. III'is a detail sectional view through the bridge wall'taken on the irregular line "of Fig. I, showing the flue openings therethrough.

In the drawings thesectional views are taken looking in the direction of the little ai'rowslat the ends of the section lines and similar numerals'of reference refer to similar parts throughout thejseveral views.

Referringgto the numbered parts of the drawing, 1 is theupper drum of a vertical.

usual water tubes between the base and upper drum. dis the usual casing surroundmg the same. 5 is the firebox or furnace, preferably provided with an automatic stoker 6 with the ashpit 7 below. 8 the footlng walls for supporting the boiler and 9 the bridge wall having a series of 'fiue passages 10 therethroughfor delivering heat and the products of combustion directly into the front of the boiler. 11 is the vertical partition extending from the base 2 up towards the top drum 1 to compel the products of combustion to ascend through the tubes, pass over the partition wall and then down to the flue opening 12, which leads to the stack 13. These parts, with the exception of the bridge wall, are in a usual form of water tube boiler. w

14 is an auxiliary header disposed transversely to the lower front portion of the upright tubes of the boiler and having a portion of the tubes 15 deflected and connecting therefrom to the top drum, and another portion 16 connecting from the base and deflected and connected to the said header 1 1. 17 is the front header of the boiler resting upon the front wallof the furnace, 18 a series of obliquely disposed water tubes extending. from their front header 17 upwardly and rearwardly to the auxiliary header 1 1. A transversely disposed partition 20 divides the rear portions of the boiler tubeslS into an upper and lower group affording a double passage for the products of'combustion which pass directly up from the firebox 5, these water tubes being'disposed directly above the firebox. An oblique casing 19 closes the top of the chamber within which the oblique water tubes are disposed, the same being closely conformed thereto to retain and guide the heated products of combustion in close relation to the said pipes and deliver them through the passage way 14; above the header 1 1. A considerable part of the productsof combustion are delivered underneath the header because of the deflecting partitionwall 20. p

21 is a pipe connection to the bottom of the boiler. 22 is a blow out pipe from the bottom of the-header, 17, and 23 is a feed pipe connecting to the top of the header 17 the same being associated with the usual feed pipe 23 for delivering water to the m i pa t f the boiler. 2 is a ci u a i n pipe from the header 14 to the top drum l of the boiler. .is a water columngage at the top drum of the boiler.

I have shown my improved water tube boiler in the form preferred by me, but desire to state that it can be considerably varied in its details without departing from my invention. I desire to clalm thesame 1n the precise form in which I have illustrated it and also desire to claim the same broadly as pointed out in the appended claims,
