CIRCULATING-VJ'ATER HEATER.

Application filed. August 27, 1924. Serial No. 734,455.

bathing, the design of which being ofv great simplicity, will greatly reduce the cost of manufacture and at the same time minimize the cost of operation.

The general configuration of this I invention makes it readily adaptable for horizontal suspension from any ceiling or it can be placed horizontally or vertically upon any wall, thus solving a great problem of installation in buildings of present day construction.

Other objects and advantages will be pointed out in the course of the following description.

In the accompanying drawings forming part of this specification Fig. 1 represents a fore-shortened plan view of my invention.

Fig. 2 is a cross sectional view taken on line 1-1 of Fig. 1.

Fig. 3 is a cross sectional view on the line 22 of Fig. 1 showing a preferred embodiment of my invention incrusted within a retort of non-emitting heat substance and also the method of how the heating elements come in contact with all the heating surfaces.

Fig. 4 is a front end view of Fig. 1 showing the outlet and inlet pipes ready to be connected to the water supply system.

Similar characters designate like parts in all the views.

My invention consists of a concave shell 1 containing a water heating chamber 7, to which atone extremity is connected an inlet pipe 2 by a union 3 having an inlet 8 and also to which at the other extremity an outlet pipe 4 by a union 5 havingan outlet 6, the outlet pipe acting as a. partial support for the inlet pipe, and their openings into the shell chamber being at oonosite ends of the heater constitute a heating system whereby the water flowing in and out of the heater goes through three different stages of heat intensity.

The concave shell l-is incrusted within a retort of some refractory material or of other non-emitting heat material 13, a preferred arrangement being shown in 3, the gas jets 14 opening from the supply pipe 12 are so arranged as to strike and deflect heat to all heating surfaces as indicated by the miniature arrows withln the re tort, thus obtaining maximumiheating ef ficiency.

' The inlet pipe 2 is subjected firstly, to

heat from thetimeit entersthe front end of the retort and continuing down the length and returnlng back again until its discharge into the shell opening 8 as shown by direction arrows 9. Secondly, the wa-' tor-in the shell chamber is. subjected to intense heat through the thin wall of the chamber shell during its circulation throughout the length of the retort until it reaches the discharge opening 6 into the outlet pipe l where it is again subjected to still further heat treatment in flowing from the rear to the front end of the retort where it leaves the Water heating chamber 7 as indicated by direction arrows 11.

As a result of these three stages of heating from the time the cold water enters the retort until its final discharge from the heater, being subjected to an intense heat throughout the various heating stages, it is quite apparent by the difference in temperature of the water to be obtained by using this method of circulation.

I wish to state in conclusion that although the illustrated example constitutes a praclical embodiment of my invention, I do not wish to limit myself to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

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

1. A circulating water heater comprising a retort, a shell having spaced walls disposed therein, an inlet pipe extending within the retort along the longitudinal axis thereof from its front end to adjacent its rear wall and returned from that point to said front end and there connected to the shell, and an outlet pipe connected to the rear end of the shell and engaging in supporting relation said inlet pipe and extending parallel with the same to the front end of the retort, said pipe and shell elements having surfaces arranged for direct exposure to heat within the retort and adapted to subject any water circulating through them to three stages of heat treatment, the first Within the inlet pipe, the second Within the concave shell, and the third Within the outlet pipe.

2. A circulating Water heater comprising a retort, a Water holding shell having spaced Walls disposed therein, an inlet pipe :disposed Within the outlines of the Walls of said shell and extending along the longitudinal axis of the retort from the front end to adjacent the rear end and returned from that point to said :front end :and there con-- rented to the :shell, :an 'outlet :pipe connected to :the rear end of the shell and extending parallel With said axis to the front end o f the retort, said .pipe :and shell elements having surfaces arranged for :direct exposure to heat within the zretort and adapted to subject any water circulating through them to three stages 'of heat treatment, the firs't Within the inlet :pipe, the second Within the concave shell, and the third Within the out let pipe.

A circulating water heater comprising a retort, a Water holding shell having spaced Walls disposed therein, an inlet pipe disposed Within the outlines of the Walls of said shell and extending along \the longitudinal axis of the retort from the front end to adjacent the rear end and returned from that pointto said front end and there connected to the shell, an outlet pipe connected to the rear end of the shell and extending parallel with said axis *'to the front end of the retort, and means for generating heat Within said retort, said pipe and shell elements having surfaces arranged for direct exposure to heat Within the retort and adapted to subject any Water circulating through them to three stages of heat treatment, the first Within the inlet pipe, the second Within the concave shell, and the third Within the outlet pipe.

In testimony whereof I have hereunto set my hand at 'Los Angeles, California,

this 22nd day of August, 1924. 4
