WATER HEATER.

Application filed Nbvember 6, 1922. Serial No. 599,271.

This invention relates to' improvements in water heaters.

Themain objects of the invention are: First, to provide in a. water heater of t the coiled type an improved coupling and supporting means for the coils within the casing.

Second, to provide 'in a water heater an improved coupling member which greatly 1 facilitates the assemblin of the parts, avoiding the necessity or brazing and soldering.

Third, to provide an improved water I heater structure in which the coils may be readily removed and replaced should occasion requires 7 Further objects, and objects relating to structural details, will definitely appearfrom the detailed description to follow. I accomplish the objects of my invention by the devices and means described in the followin specification. The invention is clearly %efined and pointed out. in the claims.

" 5 A structure which is a preferred embodiment of my invention is;clearly illustrated in the accompanying drawing, forming a part of this application, in which: Fig. I is a side elevation of a water heater -80 embodying the-features of my invention, the same being shown mainly j 1n conventional form.

Fig. II is a vertical central section through the casing.

85 i Fig. III is a detail view partially in horizontal section on a line corresponding to line 3-3 of Fig. II. y y

Fig. IV is a detailsection on a line correspondin to line 44 of Fig. III.

0 Hi V 1s a detail section on a line correspon ing to line 5-5 of Fig. II.

In the drawing similar reference characters refer to similar parts throughout the several views and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the casin of the heater, 2 the base and 3 the top t ereof. The top is-provided with 6 a vent flue 4. The burner is conventionally illustrated at 5.' The

heatingcoils

6 and 7 are disposed one within the other, the wind of the coils being opposite. These coils are connected to the water discharge and supply pipes and are supported

bythe couplings

8 and 9; The coupling 8 is provided with oppositely disposed

arms

10 and 11 having coupling nuts '12 adapted to clamp the flange ends of the coils against the ends of the arms. This form 'of coupling bein old it is not detailed. The arms are dlspose oppositely as stated and are of such length that one does not interfere with the manipulation ofthe coupling member of the other. The coupling member 8 is disposed through an opening 13 provided therefor in the side of the casing near its lower end and has stop lugs 14; which are clamped against the inner side of the casing by means of the nut 15, the projecting end 16 of the coupling member being threaded to receive the nut and also the pipe coupling 17. Lugs 18 engaging recesses or notches 19 in the edge of the opening 13 support the couplin member 8 against rotative movement. T e coupling member 9 is provided with arms 20 and 21 equipped with the coupling nuts 12, this coupllng member being disposed through the hole 22 in the top of the casing and being provided with lugs 14 which are clamped against the inner side of the easing by the nut 15, lugs 18 being provided to prevent rotative movement of the coupling member.

The discharge pipe the projecting end of the coupling mem With the partsthus arranged the coils are effectively supported. as well as being connected to the supply and discharge pipes and should occasion require a coil may be renewed or removed for cleaning should it become clogged. v

The coils are connected to the couplings without the aid of brazing, as is general practice, and, in installing the heater all that is required is to attach the pipes by means of the usual standard plumbing couplings or connections.

Myimproved couplings are very economical to produce and use of the same results in a'very decided economy in assembling in the heater and in attaching the heater to or installing infa house system.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
