WATER-HEATER.

Specification of Letters Patent.

Application filed. January 20, 1920. Serial No. 352,805.

T 0 all whom it may concern.

Be it known that I, SAMUEL C. SMITH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Water-Heaters, of which the following is a description.

My invention belongs to that general class of devices known as heaters and relates particularly to a heater attachment to be used in connection with gas, oil,v or other stoves, for heating water. The device is particularly adapted to be employed upon any of the well known types of gas, oil, or other stoves now on the market, Without materially changing or rebuilding the stove. The invention has among its objects the production of a device of the kind described that is simple, convenient, durable, efiicient, economica-l, and satisfactory for use wherever found applicable. It has particularly as an object the production of'the device of the kind described that will almost instantly heat the water to a high temperature, and which may utilize the heat or flame which is at the same time used for heating or cooking purposes. There more than one heater is employed upon the stove, the same also may be utilized as a warmer, taking the place of a warming oven. Many other objects and advantages of the construction herewith shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts,

Figure 1 is a plan view of a portion of a gas stove equipped with a plurality of heaters;

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

Fig. 3 is an enlarged sectional view taken substantially on line 3-3 of Fig. 2;

Fig. 4 is a sectional view taken substantially on line 44 of Fig. 8;

Fig. 5 is a plan view of a slightly modified construction;

Fig. 6 is a sectional view taken substantially on line 6-6 of Fig. 5;

Fig. 7 is a sectional view taken substantially on line 7-7 of Fig. 5; and

Fig. 8 is a sectional View taken substantially on line 8-8 of Fig. 7.

Referring to the drawings, 1 represents one or more gas burners of any desired type, that shown being a type in which there is provided a plurality of small holes or openings through which the gas escapes and may be lighted; The particular burner shown is also of the star shape design. I'have shown a portion of the gas stove, consisting of the top part 2 with the parts 33 carried there by and which carry the arms 4, upon which the articles to be heated in vessels or pots are supported above the flames.

Patented Nov. 29, 1921. a

Any number of heaters or heater units one will suffice for all. The type of heater shown in Figs. 1 to 4: inclusive, consists of a plate 6, having a flange 7 about the out side of the same, 8 being a plate arranged upon the opposite side, and 9 a gasket or the equivalent, preferably of copper or the equivalent. The parts 6 and 8 may be secured together by bolts or screws 10, or the equivalent, for the purpose. The part 6 is provided with a plurality of extending or projecting parts 11, which closely fit against the gasket, 9. These parts are formed with openings 12 through the same so that they are tubular, and they substantially const1tute a series of fines. The gasket 9 and plate 8 are formed with openings or apertures 15 and 16 respectively therethrough. The flues in the preferred construction are arranged so that they register with the openings 17 in the burner, and the heater is set down substantially close to the burner or is supported thereon if desired. Their arrangement, shape and size generally corresponds to the shape of the burner, and the size, shape and location of the openings in the burners. The heater is provided with shown, and the gas turned on and lighted, the flame will extend from or through the openings 12 and heat the articles carried on the arms 4. Obviously a part of the heat will be distributed in the plate 6 and through the fines 12. I have found from practical experience that the heater is sub- .stantially instantaneous in operation and that the same does not interfere with the usual use of the stove.

In the construction shown in Figs. 5 to 8, the operation is the same, but in this case there is shown substantially two elongated fines. This particular type is mounted above the burner similar to the other construction described. Referring to the figures, 28 and 29 represent two spaced tubular shells having chambers 31 formed thereon. The two parts however, are spaced so that there are spaces substantially constituting lines between the inner and outer parts. They are connected however, as at 3232, and provided with an inlet pipe 33 and a discharge pipe 8 Obviously as the heat passes up betweenthe two shells it heats the contents of the same.

Having thus described my invention it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

VJhat I claim as new and desire to secure by Letters Patent is:

1. A water heater of the character described, comprising a chamber formed of cooperating parts, a water feed inlet at one portion of the chamber, and a water di charge conduit at another portion thereof, said chamber having a plurality of noncommunicating flues disposed in an irregular path so as to present a maximum heating surface to the water entering the chamber to intensely heat the same prior to its discharge, and a burner disposed beneath noncommunicating flues to permit heating gases to pass through the lines.

2. A water heating attachment, comprising a chamber consisting of two parts, a water inlet to said chamber and a water discharge leading therefrom, one of said parts having extensions projecting therefrom, a plurality of separated vertically disposed fiues passing through said extensions through apertures in alinement with the fines in the other part forming said chamber, the flues receiving heating gases to intensely heat water surrounding the projecting parts prior to the discharge thereof.

8. A ,water attachment of the kind described, comprising a water chamber having an inlet and outlet, the walls of said chamher being provided with extensions disposed in an irregular path and surrounded on both sides by the water introduced to the chamher, said extensions being formed with a plurality of vertical bores passing therethrough separated from one another by the material of which the extensions are formed and constituting a series of flues.

4. A heater of the character described, comprising separated members forming a chamber, a water inlet leading to said chamher and an exhaust leading therefrom, one of said members having a plurality of projecting extensions disposed in an irregular path and adapted to be surrounded by water introduced to the chamber, said extensions having separated fines passing therethrough, the other member of said chamber being provided with. apertures alining with said flue openings.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
