Application mea August as, 1925.

VThis invention relates to improvements in water heaters.

The main object of this invention :is to provide an improved water h eater which is and economical iny its parts and which may be easily assembled or disassembled as occasion may require.

Objects pertaining to detailsiand economies of construction and operation of my invention will definitely appear detailed description to follow. i Y

I accomplish the objects of vmy invention by the devices and means The invention is clearly defined and pointed out in V the claims.

A structure embodying the features of my invention is clearly illustrated in theaccompanying drawing forming a application, in which: v

Fig. 1 is a side elevation of my improved water heater.

Fig. 2 is a central section on a line 2-2 of Figs. 3 and 4. n l

Fig. 3 isa horizontal section on a line corresponding to line 3-3 of Fig. 2.

part of this detail view partly in vertical Fig. 4 is a horizontal section on a line corresponding to line`44 of Figs. 1 and 2.

Fig. 5 is a detail vertical section on a line corresponding to line 5-5 of Fig. lpsliowing details of the casing structure. j

Fig. 6 is a detail view partially in horizontal section on a line corresponding to line 6-6 of Fig. 2. l

Fig. 7 is a fragmentary perspective view of the inner casing. 'j

Fig 8 is a perspective viewrof the casing ring.

In taken looking in arrows at the ends of the section lines and similar numerals of reference indicate simivlar parts in all of the views.

Referringv to the drawing, the base 1 is supported by suitable legs 2. This base has an upwardly projecting bead 3 at'its outer edge providing a seat for the bottom casing section or member 4. The burner 5 rests upon this base, the casing section 4 and the base providing a burner housing or chamber.

The section 4 has air inlet openings 6 adjacent the lower end thereof, an inclined shell7 being arrangedabove these openings the drawing the sectional views are v inside ofthe casing is from the described in the line corresponding tok the direction ofthe little f Serial No. 53,075. so that any condensation running down the openings. f

The base 1 is provided with a drain 8. Restingy upon the bottom casing section 4 is a casing ring 9 of cruciform section, the downwardly projecting vertical arm 10 of kwhich Vis arranged within the casing section` 4 while the outwardly projecting arm 11 thereof rests upon its upper edge. The top casing section 12 is removably mounted on this casing ring upon the arm 11 of the ring whilev the upwardly projecting arm 13 of the ring projects into the casing, thus properly alining and supporting the casing section. y

The top 14 rests upon the upper end of the casing 12 and is provided with a central openingl. The top 14 also has upwardly projecting supporting members 16 for the cap 17, the cap having downwardly projecting lugs 13 engaging within the supporting member 16. The cap carries a deflector 19.

An inner casing wall 2O is provided, the lower end of which is arranged within the inwardly projecting arm 21 of the casing ring. This wallr has an annular bead 22 providing a shoulder resting upon this arm of the casingring so that the inner wall is centered and supported within ythe .outer wall or casing. This inner wall is provided with a top section 23 having a central hole 24 therein registeringY with the hole 15 in the casing top 14.

The heating coil 25 has a centrally disposedreturn pipe 26 which is connectedto the upper end 27 of the coil by a coupling 28. This coupling'QS carries a stud 29 passing through 31, the spider enga-ging the openings in the casing top and the inner wall top.

The coil is further supported and positioned by the discharge pipe 32 and the water inlet pipe 33, the pipe 32 being connectedto the lower end of the returnvpipe 26 of the coil-by means of the coupling 34 while the inlet pipe 33 is provided with anarm 35 engaging withthe coupling,'thus providing a cross member at the bottom of the coil which rests upon the casing ring 10. This casing ring is notched to receive the

pipes

32 and 33.

A tie rod 36 extends downwardly from the coupling Ymember 34 through the bottom 1 to receive theclamping nut 37. Y The supdefiected from the j. 1 1 at its lowei edge, iesting y ported, said .inner pipe to the lower end of porting; web for the pilot 39 on the burner has a hole therein to receive this rod; the rod, however, is removable without reinen ing the burner when the nut 3T is disengaged. u

lille burner is provided with a supply pipe i0 controlled by the valve nlechanisin design nnted generally by the numeral Ll-l and operatircly associated with the water inlet ll. The water supply pipe .shown ut l2, see Fig'. l. its this valre inerhanisni forins no part of niy present invention, it is not described in detail herein.

The valve mechanism connected to the pipe 33 by a coupliup` dii. The gas supply pipe is not illustrated.

In assembling. the coil and discharge and supply pipes are assenibled as ny unit, the tie rod 3G with the stud 39 beingl also a part ofthis unit. When the cashinassembled, the bottoni section placed upon the base and the burner put into position. A coupling erlis provi led as a part ot the casing to receive the pipe el() it'roin the outside olfthe casing.

The casino rinol heine mounted on the secci :a t. C

tion -t ut the casina, the coil nuit is pnt ii i position. 'llhe inner caring; wall, which notched at el?) to receive the supply and discharge pipes is set in place, the outer casing, which is also notched to engage these pipes, is put; in place, the top Llplaeed thereon, the spider arranged to engage the openings in the casing top and inner wall top, and the stud on the coil and tno nuts ill and Sli" are engaged. which elleetivelji' centers and elainps the parts in position. The cap 1T is :freely ren'iovable.

The parts can be disassembled inerely by removing the nuts 3l and 3T.

The parte ot in v improved heater are very siinple and economical in .structure and,` as stated, inay be very easily assembled or dis assembled.
