PATRICK J. McIN TYRE, OF WATERBURY, CONNECTICUT, ASSIGNOR- TO THE NATIONAL COMPANY, OF WATERBURY, CONNECTICUT, A CORPORATION 03 CONNECTICUT.

WATER HEATER.

Application filed May 13,

To all whom it may concern:

Be it known that I, PATRICK J. MCINTYRE, a citizen of the United States, residing at l/Vaterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Water Heaters, of which the following is a specification.

The invention relates to a Water heater, and more. particularly to the class of heaters for use in city or suburban homes, barber shops, lunch rooms, drug stores, hospitals, first-aid stations, factories, or at any desired place, where an instantaneous apparatus may be desired.

The primary object of the invention is the provision of a. water heater of this character, wherein the construction thereof is novel in form, to enable the operation of the same at a minimum cost and by the use of any type of burner, either gas or kerosene, as the water within the heater can be heated within one minute after the lighting of the burner.

Another object of the invention is the provision of a water heater of this character, wherein the water container is elevated considerably above the burner, and the heat from the latter is conveyed centrally through the container from a chimney supporting the same, which chimney contains a water coil, through which the products of combustion pass, the coil being in communication with thecontainer and is supported in the chimney in a. novel manner.

A further objectof the invention is the provision of a water heater of this character, wherein the water container is provided with pockets for receiving towels, medical instruments to be sterilized, or food to be kept warm, these pockets being of novel form, so thatthorough heating thereof can be had. r

A still further object of the invention is the provision of a water heater of this character, wherein the Water container has the center exhaust fine for the waste products of combustion constructed to transmit heat from the waste heat that is not taken up by the water coil within the chimney, so as to positively heat the water in the container, causing a circulation in the latter, whlle this circulation is greatly accelerated by the overflow from an overflow pipe within the container, from which hot water is flowing 1922. Serial No. 560,735.

all the time that the heat from the burner is applied to the water coil in the chimney.

A still further object of the invention is the provision of a water heater of this character, which is extremely simple in construction, readily portable, thoroughly reliable and efficient in its purpose, strong, durable, and inexpensive to manufacture.

l/Vith these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the'claims hereunto appended.

In the accompanying drawings:

Figure l is a side elevation of the heater constructed in accordance with the invention and a portion thereof being partly broken away.

Figure 2, is a fragmentary top plan.

Figure 3, is a sectional view on the line 3-8 of Figure 2.

Figure -l-, is av vertical longitudinal sectional elevation. V

Figure 5, is a fragmentary side elevation of a modified form of a tank or container, the same being broken away or shown partly in section.

Figure 6, is a fragmentary side elevation of the lower portion of the modified form of hot water heater, the same being also partly broken away.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings, in detail, A, designates generally a base, of any desirable style and construction, B, the cylindrical chimney, perferably made from sheet metal. and is supported slightly elevated from the base A, through the medium of legs 5, which are fastened to the latter and also to the lower end of the chimney.

Telescoped into the upper end of the chimney B, is the lower flange portion of a truncated cone shaped flue C, integral with and centrally of a water container or tank D, this fine being extended vertically througl'i the container or tank D, and opens through the top thereof. The flange 6, of the flue C, is fastened to the chimney through the mediiun of bolts 7, although other means of fastening may be employed.

In the bottom of the container or tank lUU I), are plug nipples 8, in which are fitted removable screw plugs 9, so that in one of the nipples 8, on the removal of the plug, can be engaged at faucet (not shown) so that water may be drained from the container or tank into abasin or other receiver, as the occasion may require, wh le the other nipple 8, is adaptable for engagement with a water supply pipe leading from av main, should it be desired.

Located within the water container or tank is a water gage tube 10, in which is arranged a float gauge 11, the stem 12, of which works through the top of the container or tank D, to enable a person to determine thewater level in the latter.

Mounted in the water tank or container 1), opening through the top thereof and depending from the same are cup shaped pockets 13, each having in its side wall a vertical row of spaced openings 13, for the circulation of moisture or heat therein, while closing the pockets at the top of the container or tank are removable covers 1 having hand grips l5, thereon. in these pockets 13, are adapted to be received towels, medical instruments to be sterilized, orl ood to be warmed.

\Vithin the chimney B, centrally thereof is a copper water coil 16, the upper end of which is tapped into a coupling 17, while the other end portion 18, extends upwardly centrally of the coil 16, to constitute a riser tube, the latter terminating in the upper portion of the flue C, and is engaged in a coupling 19, which has leaning from one side of the same an overflow nozzle 20, .the same being passed through the flue wall into the water container or tank. Leading from the other side of the coupling 19, is a draw-oil tube 21,which extends through the wall of the container or tank B, and has connected therewith a faucet 22, for the discharge of hot water as the occasion requires. I

Arranged within the upper portion of the chimney B, immediately below the plane of the bottom of the container or tank D, are opposed water heating coils 23, the ad- "ja'cent ends of which are engaged in the coupling 17, while the other ends 24. are carried upwardly and laterally througl'i the \all of the flue C, for communication with the container or tank near its bottom.

lhe coils 23. are supported on a cross rod 25, engaged :inthe chimney B, while the coil 16, is engaged with certain of the fasteners 26, securing the legs 5, to the chimney, and in this manner the coil 16, is supported in the latter.

Resting uponthe base A, is a suitable gas or oil burner, 27, of any desirable type, which 'when lighted heats the coils 16, and 53 it being observed that by reason of 111:;- iormation of the flue C, the waste heat conveyed throughthe chimney, will be transmitted to the container or tank for the heating of the water therein, causinga circulation of the water within the same This circulation is greatly accelerated by the overflow from the nozzle 20, from which hot water is flowing all the time that the heat is applied to the coils 16 and 23, from the products of con'ibu stion from the burner.

In the Figures '5 and 6, there is shown a slight modification of the invention, wherein the water tank (ii-container D, has the coupling 28, at the upper portion of the riser-tube 29, fitted with a removable plug 30, soithat said tube can be cleaned and also the coil'as pressure may be applied when said plug is removed.

Formed near the bottom out the container or tank is a cylinder fi'il, which constitutes a guard for the drawt tube- 32, which is tapped at 33, in the 'oli'set portion 34, of the riser-tube 29, and this tube 32, has connected therewith the faucet 35, the cylinder prevents cold water. from coming into con tact with hot water or draw-off tube 32 leading to said ta'ucet 35, as will 'be apparent.

Leading from the coupling 28, is a laterally disposed nipple 36, to which is detachably connected a pipe. 37, the same being trained down 'ardly along the inner wall ot the container or tank and terminates close to the bottom thereof so that hot water discharged through saidpipe 37, near the bottom of the container or tank mixes with the cold Water and starts a vigorouscirculation within said container or tank with a result that allot the water becomes hot therein at practically the same time. 7

In the side wall. of the container or tank D, is tapped a rern'ovable plug 38, in sub. stitute for plug 9, hereinbet'ore described.

The cup-shaped pockets 39, in the to of the container or tank 1), are formed wit toraminous material "so that the water may be filtered when poured thereto into the contain-er or tank. .This material is only used when the container or tank is not connected to some water system at the point 8, hereinbetore described.

In Figure 6, there is shown the lower por tion of the hot water heater and coil '16, has tapped therein and with the riser-tube 18, a T 40, fitted in onearin with a removable plug t1, 'to permit the cleaning of said coil when occasion may require.

From the foregoing it is thought that'the construction and manner of ope 'ationof the 7 water heater will be clearly understood, and therefore, more extended explanation has been omitted.
