WATER HEATER.

Application filed July 26, 1924. Serial No. 728,386.

My invention relates to a heater for water and other liquids hereinafter termed a water heater, and particularly relates to a heater of. the kitchen boiler ty 3c.

The general object o my invention is to provide a heater of the indicated type adapted to be heated by a gas burner, a more specific object of the invention being to provide a practical and simple construction by which water in the boiler or container may be heated or the water in an external pipe forming part ofthecirculating circuit heat ed with increased rapidity when a limited quantity of hot water is desired for immediate use.

A. further specific object of the invention is to provide a heater in which outside pipes of the circulating circuit are given a form to constitute a loop on which cooking utensils, such as a frying pan, pot or kettle, may be seated, the loop being of a character to accommodate the cooking utensil without obstruction by the burner or parts of the heater.

The nature of my invention and its distinguishing features and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a perspective View of the heater embodying my invention;

Figure 2 is a sectional plan view; and

Figure 3 is a vertical section taken through the lower portion of the heater.

In carrying out my invention in accordance with the illustrated example, a boiler or vertical liquid container is provided which is, in practice, of the general form of kitchen boilers. From the boiler 10 an outlet pipe 11 extends horizontally or approximately so and is continued downwardly as at 12 and formed into a horizontal loop 18 from which rises a pipe 14 connecting at its upper end with a horizontal pipe 15. The pipe 15 leads to a four-way fitting 16 or equivalent chamber having four connections. The fitting 16 connects by a short horizontal pipe 17 with a valve 18, from which a short pipe 19 leads at right angles or approximatey so, said pipe 19 constituting the inlet to the boiler 10 and terminating within the boiler in an upwardly directed nozzle 20. Thus 14 connected with said loop.

the pipe 11 constitutes the cold water pipe and the pipe 19 the hot. water inlet pipe. It is to be noted that the nozzle 20 extends above the point of connection of the pipe 11 with container 10; hence the discharge through said nozzle being at a higher point than the connection with the pipe 11, said nozzle constitutes a terminal of a hot-water inlet pipe for the container. In practice the nozzle 20 rises to whatever height is neces sary to serve its purpose as a hot-water inlet terminalv The loop 13 is approximately semi-circular in practice and is disposed at one side of the down pipe 12 and uptake pipe the pipe 13 is disposed over any approved burner A, which may be one of the burners of an ordinary gas stove, or said loop 13 may be disposed in the grate of a kitchen stove or the like, but the heater is designed T- more particularly for use with a gas burner.

The horizontal pipe 15 connects with the fitting 16 at one side, and directly opposite, in practice, I connect the water pipe 17, said pipe 17 leading to the valve 18 and'hot water inlet 19. A discharge pipe 21 makes a third connection with the fitting 16, and said discharge pipe is provided with any approved bib 22.

The valve 18 is positioned between the connection of the bib 22 with the fitting 16 and the hot water inlet 19 so that the flow to said inlet pipe19 may be regulated or the flow entirely out 01?.

With the described construction, when the valve 18 is opened the circulation will be from the boiler lOthrough pipes 11 and 12 to the loop 13, the pipes 14: and 15 to the fitting 16, and from the latter through pipe 17 valve 18 and pipe 19 to the boiler. lVhen, however, rapid heating of a limited quantity of water is desired, the valve 18 may be closed, and thereby the water in the loop 13 and pipe 14: will be rapidly heated, so that by opening the bib 22 water heated to a high degree may be drawn oft from the circulating circuit without the delay of heating the body of water in the boiler 10.

From the fitting 16 rises an expansion standpipe 23 capped at its upper end, the cap having a minute vent orifice 2 1, so that if the valve 18 be closed and also the bib 22 and ebullition develops, the water or other liquid may rise in the expansion pipe 23. Pipe 23 is employed arranged as shown when In practice,

gravity pressure alone is employed and in practice the top of the pipe 23 is above the water level in container 10.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the mechanical details herein illustrated, since, manifestly, the same can be considerably varied wthoutdeparture from the spirit of the invention as defined in the appended claims.

VHaving thus described my invention, 1

, claim:

1. A heater for liquids, including a boiler,

an outlet pipe leading from the boiler, a depipe, a rising pipe connected with the other end of said loop, means connecting said rising pipe with said boiler to return the liquid to the boiler,abib on said connecting means,

and a valve in said connecting means between the bib and the return connection with the boiler to optionally cut oil the liquid returned to the boiler for the more rapid heating of the liquid flowing through the loop and the bib; together with a pipe rising from said connecting means, said last mentioned pipe being vented at the top.

2. A heater for liquids, including a boiler, an outlet pipe leading from the boiler, a loop adapted to be heated, said loop being connected with said outlet pipe, a return pipe connected with the other end of said loop, a fitting to which the last mentioned pipe discharges, a connection between said fitting and the boiler to return the liquid to the boiler through the loop, a bib on said fit- 7 ting for drawing ofi liquid from the fitting,

and a valve between the bib and the return connection of the boiler; together with a vented riser pipe on said fitting.
