WATER-HEATER.

. Application filed. April 26, 1920.

T 0 all whom it may concern:

Be it known that I, ALFRED N. CLOUGH, a citizen of the United States, and resident of Sunnyvale, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Water-Heaters, of which the following is a specification.

It is the object of my invention to provide a water heater in which the water is heated upon the interior and exterior of a flowing stream and in which certain means are provided for absorbing heat from an external source and conveying the same to the said flowing water, and which may be easily disassembled for cleaning.

In the drawing Figure 1 is a vertical cross section through a heater embodying my invention.

Fig. 2 is a section on line 22 of Fig. 1.

Fig. 3 is a vertical cross section through another embodiment of my invention.

Fig. 4 is a section on line 4-4 of Fig. 3.

Fig. 5 is a section on line 5-5 of Fig. 3.

Referring to the embodiment shown in Figs. 1 and 2, 1 is a water pipe provided with an elbow at 2 and a vertically extending portion 3. At 4: is shown a rod of smaller diameter than pipe 3 placed therein and concentric thereto and held in position by a threaded engagement at 5. The lower end of rod 4 preferably carries an enlargement 6 and referably a plurality of projecting pins these parts 4, 6 and 7 being made of suitable heat conducting material. On pipe 3 are formed a number of vanes 8 which are also of heat conducting material. At 9 is shown a cone shaped member fitting closely over vanes 8 with a discharge opening at its upper end as at 10 and extending downwardly a suitable distance around member 6. A suitable gas or oil burner is indicated at 11 so positioned as to heat members 6 and 7, the products of combustion passing upwardly within cone 9 and discharging at 10.

In operation water is permitted to flow through pipes 1 and 3 but on account of rod 4 it must move through pipe 3 in a comparatively thin tubular stream. The burner 11 being in operation the members 6 and 7 are heated to a comparatively high temperature, rod 4 also being heated by conduction. The heat generated by burner 11 is gathered within cone 9 thereby heating pipe 3 and vanes 8 as well as inclosing cone 9 and a Specification of Letters Patent.

portion of pipe 1. The heated vanes 8 serve to assist in increasing the temperature of pipe 3 and to maintain the same at the temperature reached.

The result of this construction is that the water flowing through pipe 3 is quickly heated through because of the large surfaces it presents to the heated members it being heated simultaneously from within and from without.

In Figs. 3 and 4: an embodiment of my invention is shown in which a plurality of the devices are inclosed in a single chamber 12 having an outlet at 13 and a burner at 14, the latter being supported in a casting 15 which supports the chamber 12 and the several individual devices. In this construction the casting 15 is provided with conduits 16 leading to the several pipes 3 from supply pipe 1, and a single discharge pipe for hot water is provided at 17 with which all of the said pipes 3 communicate.

It is evident that in a construction of this kind with a single burner heating several devices, and a continual flow of water passing through each device, the water can be heated in large quantities in a short period of time, the number, arrangement and proportions of the devices depending of course upon the quantity of water to be heated within a given time.

It is understood that changes in form, construction, and method of operation may be made within the scope of the appended claims.

I claim 1. A water heater including a water pipe having radially extending and longitudinally arranged heat conducting vanes mounted upon the exterior thereof, a heat conducting rod of less diameter than said pipe axially mounted therein and projecting therefrom, an open ended conical member supported on said vanes, and means for heating the projecting portion of said rod, the inclosing pipe, and said vanes.

2. A water heater including a water pipe having heating conducting elements mounted upon the exterior thereof, a heat conducting rod of less diameter than said pipe axially mounted therein and projecting upon the exterior thereof, a heat conducting rod of less diameter than said pipe axially mounted therein and projecting therefrom,

means for heating the projecting portion of said rod, the inclosing pipe, and said heat conducting elements, and means for inclosing said pipe and heat conducting elements to form a plurality of passages for the heating medium generated by said heating means.

4. A Water heater including a plurality of parallelly disposed Water pipes,
