6 Claims.
My invention relates to heating apparatus such as boilers, furnaces, and the like, audit has for a broad object to provide a new and improved form of baiile structure which functions to direct the flow of the combustion gases and to protect the defining walls of the combustion chamber.
A further object is to provide an improved form of crown sheet baiiie for heating apparatus which is simple in form and is inexpensive to make and which can be readily inserted and taken out through the furnace door and which can be easily and readily assembled in itsoperative position.
The invention consists in the novel construction and combination of parts, to be more fully described hereinafter, and the novelty of which will be particularly pointed out and distinctly claimed.
In the accompanying drawings, to be taken as a part of this specification, I have fully and clearly illustrated a preferred embodiment of my invention, in which drawings- Fig. 1 is a longitudinal vertical section showing one preferred embodiment of my invention, the view being taken on the broken section line l'-| of Fig. 2 and also including the lower part of the combustion chamber and a conventional form of fuel-burning apparatus;
Fig. 2 is a transverse vertical section taken on the line 2-2 of Fig. 1 and omitting the lowe part of the combustion chamber;
Fig. 3 is a partial plan section taken on the line 33 of Fig. 1;
Fig. 4 is a detail view showing in perspective one of the plate members which when assembled with another plate member similar to the one shown, forms a crown sheet baflle; and
Fig. 5 is an enlarged fragmentary vertical section taken on the line 5-5 of Fig. 3.
Referring now in detail to the construction illustrated, I have shown my invention as embodied in a conventional form of heating apparatus, known in the art as a vertical sectional cast iron boiler. It will be appreciated, however, that, in so far as the broader aspects of this invention are concerned, it is not limitedin its application to the particular type of boiler, or furnace, which is shown,for the invention can equally as well be incorporated in a varietyof other types of heating apparatus.
In the drawings, the boiler is indicated in its entirety by the reference numeral I0 and comprises the usual back section II, front section I2, and one or more intermediate sections, there being two in the boiler disclosed, said sections being indicated by the numerals l3 and I4, respectively. The several sections are assembled in vertical side-by-side relation and the hollow interior spaces therein are connected at their lower ends by the usual small water flow nipples IE (only one being shown) and at their upper ends by large steam and'water flow nipples l6, so that the boiler water may freely circulate between sections and the steam from all sections may flow freely to a steam outlet connection I! which may be formed in any desired section, for example, the intermediate section I l, The normal water level is indicated at l8. The boiler l0 may be operated as a hot water boiler aswell as a steam boiler.
The several boiler section are constructed so that when they are assembled in the manner shown; they provide a combustion chamber'Zfl in the lower part of the boiler, and a plurality of horizontal flues 2| in the upper part of the boiler to receive the combustion gases from the combustion chamber through the usual opening 22, here shown a being located in the top and rear of said chamber. The flues discharge such gases from the boiler through the usual smoke outlet 23. The combustion chamber 20 is defined by a pair of opposed upright sidewalls 24 and 25, respectively, a crown sheet or top wall 26 connecting the upper ends of the side walls 24 and 25, and a pair of opposed end walls 21 and 28, respectively, connected at their uprightsides to the side walls 24 and 25 and at their top to the crown sheet or top wall 26. The end wall 21 may be considered as the rear end wall and the end wall 28 asthe front end wall of the combustion chamber. The gas outlet opening 22 is here shown as being provided in the top wall 26 adjacent the rear end wa11 21. Although I have shown only one gas outlet 22, it will be appreciated that a second outlet is located at the opposite side of the combustion chamber and connecting thelatter with the left-hand flue 2 I, as viewed in Fig. 2. Access may be had to the interior of the combustion chamber through the usual door 29 .attached to the front end wall 28.
The boiler I0 is shown in Fig. 1 as being fired by a conventional gun type oil burner 30 which discharges a mixture of atomized oil and air into the lower part of the combustion chamber where it is ignited and the major part of combustion takes place. As'stated, the combustion gases flow upwardly and outwardly from the combustion chamber through the outlet opening22. The arrows in Fig. 1 indicate the path of flow of the-comibustion gases.
In accordance with the presentv invention, I
provide an improved form of crown sheet bafile structure indicated generally by the reference character 32. The baflle is spaced downward from the crown sheet or top wall 26 and from the ga outlet 22 and thereby functions to prevent the very hot combustion gases from flowing directly to the gas outlet andalso effects a more thoroughand intimate contact of the gases with the entire area of heat absorbing surface defining thecombustion chamber. Due
to this well distributed and intimate contact of the gases with the heat absorbing wall struce ture, the temperature of the gase leaving the combustion chamber is lower andthe efiiciency 'of the boiler higher.
Furthermore, the baffle structure 32 acts to reduce the temperature of the gases before striking the top wall or crown sheet 25 and consequently there .is less" likelihood of damage to the crown sheet, the latter being more vulnerable to high temperatures due e' beifiu 2 ob truc in t s m ext t the irc t water space a o th o n heet- ;v

structure may: be likened unto the. peaked roof of a house with each, plate. icorresponding: to; a
sideoftthefroof, 'and lyingi'adjacent one of the upright sidewalls. The apex ofthejV-shaped structure is shown as extendin'gforwardly away from 1a central 'pOI'tiOI'l of the reari'end wall '2'! I and. toward .theffro'nt end wall 28 "and -'lying approximately "within a? central longitudinal vert'ie cal rplane'through the boilerl andab'o'ut 'edui-" distant :from the 'two sidewalls 24 and" 25.

Each plate-comprisesfla' lower edge portion 3'! adaptedto be arrangedalongside-one of the side walls" and'an upper edge portion 38jarrang ed in abutting and mutual supporting engagement with the' upper edge 38"of the-other plate, and
each plate comprises end or lateral edge- portions 39 and 40, one of which extendsalong' th'e end wall 21, depending upon which side-of the boiler" the plate is placed. The various edgeportionsfcontribute to reinforcing th'e pIate'. 1

The outer or peripheral face of each lower edge portion 31 abuts a member 43. and the lowermost edge 31a thereof rests on the lug 42 (see Fig. As corresponding upper 5 edge portions 38 of the two plates are in abutting engagement with one another and the lower edge portion 31 are prevented from spreading or moving outward due. to lugs '42 and abutments 43, thetwo plates'are held together in assembled position by their own weight. The

It isv noted from; an.

The central portion 41 ofthe flange does not extend out to the-plane of the faces; 46a and 46b. The latter is done so as to assure abutting;engagementfof the facesof opposing. plates3ll and 35.

Each end edge portion '39 and 40 is provided adjacent the upper and lower edges 38 and 37 with spacing lugs52 and 53, so that when either plate is in assembled operative position the'lugs 52 and 53 projecting from the end edge portion thereof which is adjacent the rear end wall 21, will engage such wall 21 and space such end edge portion therefrom, so that a small flow of combustion gases will be maintained upward along the surface of wall 21 and into the gas outlet 22. This construction prevents the formation of dead gas spaces along the wall 21 beneath the bafile 32. These lugs also position the plates and prevent them from rotating about their single lower edge lug supports 42. t V a Each of the plates 34 and 35 is also provided along the lower longitudinal edge 31 thereof with downwardly extending lugs 60 one of which engages behind the side of the projection or lug 42 which is adjacent the end wall 21 and holds such plate in assembled position against and prevents it moving away from the end wall. One of the lugs 60 performs the just mentioned function when the plate is arranged alongside one boiler side wall and the other lug 60 performs such function when the position of the plate is reversed and it is arranged alongside the opposite boiler side wall.
From the foregoing, it will be apparent that I have provided an improved form of heating apparatus which includes as an essential part thereof, a simple and inexpensive form of crown sheet bafile, which can be readily inserted through a, fire door'and properly assembled in the combustion chamber after the boiler sections have been assembled.
