HEATING AND HOT WATER BOILER Filed March 21, 1957 tvv 7 IN VEN TOR.

I ATTU R N EYE United States Patent HEATING AND HOT WATER BOILER Robert L. Meyers, Cumberland, Md.

Application March 21, 1957, Serial No. 647,516

1 Claim. (Cl. 122-33) The invention relates to heating and hot water boilers designed for domestic and commercial use, and in particular a boiler having a vertically disposed center tube with a pilot and burner below the lower end, with a heating coil around the center tube and with a hot water coil in an outer water jacket or boiler housing positioned over the heating coil and tube wherein hot water from the center tube passes upwardly through a supply pipe to radiators and the like and returns from the radiators and the like through a return pipe to the heating coil around the center tube, passing from the coil to the lower end of the outer portion of the boiler and wherein hot water for domestic use is supplied from the hot water coil positioned in the boiler.

The purpose of this invention is to provide a heating boiler wherein all water supplied by the boiler is subjected to a relatively small burner with the water confined to a pocket in a center tube whereby the hot water from the confined pocket or tube is circulated through a heating system with the return water passing first into the boiler and from the boiler into the center tube or confined pocket.

Various types of boilers have been provided for heating systems, however, in substantially all boilers of this type burners apply heat to relatively large bodies of water and it is necessary to raise the temperature of all water in the boiler in order to supply hot water to radiators or other heating units and also to taps for domestic use. With this thought in mind, this invention contemplates a boiler in which the heat is directly applied to water in a relatively small container or tube positioned in a cavity in a larger boiler wherein water directly heated is carried through supply pipes to radiators or other heat exchanging elements so that only water of the boiler, at the highest temperature thereof, is delivered to the heating elements.

The object of this invention is, therefore, to provide a boiler having a cavityin the center in which a center tube is positioned wherein heat of a burner applied directly to the center tube also heats water in the surrounding boiler and wherein hot water for use is taken from the center of the center tube.

Another object of the invention is to provide a heating boiler in which heat from a burner, such as a gas, oil, coal or electric burner, is applied directly to a relatively small body of water wherein rapid circulation of the hot water is obtained and wherein water of the highest temperature of the boiler is circulated directly to heat exchanging elements.

Another important object of the invention is to provide a combination heating and hot water boiler wherein the return water passes through a coil around a center heating tube and wherein hot water for domestic use is supplied by an independent coil positioned in the boiler.

A further object of the invention is to provide an improved heating boiler wherein only a small body of water is subjected to a heat producing element and wherein the capacity of the boiler may be increased by' ice adding additional heat producing elements for supplying heat to the entire lower surface of the boiler.

A still further object of the invention is to provide a heating boiler in which heat of a burner or the like is applied to a relatively small quantity of Water in which the boiler is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a boiler having an open cavity in the lower part of the central portion, a heating or center tube extended from the upper part of the boiler downwardly in the cavity, a burner positioned below the lower end of the heating or center tube, a coil for return water extended around the center tube, a hot water supply connection extended downwardly into the upper end of said center tube, and a coil for domestic hot water positioned in the boiler and having independent supply and return connections.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing which shows a vertical section through a boiler with parts broken away and parts shown in elevation.

Referring now to the drawing wherein like reference characters denote corresponding parts the improved heat ing and hot water boiler of this invention includes a center tube 10 positioned in a cavity 11 in a boiler housing having an outer cylindrical wall 12, an upper plate or top 13, an annular ring forming a base 14, an intermediate cylindrical wall 15 surrounding the cavity 11, an upper annular ring 16 providing the upper end of the cavity, a heating coil 17 positioned in the cavity and extended around the center tube 10, a hot water coil 18 extended through and not connected to the boiler, and a burner 19 positioned below a disc 5 providing the lower end of the center tube 10.

A hot water supply tube or pipe 20 through which water is supplied to radiators, or other heat exchanging elements or devices extends downwardly through the upper portion of the boiler housing being positioned in an opening 21 in the top or upper plate 13 and extended downwardly to a point 22 in the upper portion of the center tube 10. With the supply tube 20 positioned as illustrated in the drawing, hot water from the center tube 10 passing upwardly through the central portion thereof circulates upwardly through the pipe or tube 20 with cool water of the body of the boiler passing downwardly around the inner surface of the center tube as indicated by the arrows 23 and as this water is heated by the burner at the lower end of the center tube, the hot water passes upwardly through the center and outwardly through the pipe or tube 20.

Return water from the radiators or other heat exchanging elements or devices is returned to the boiler through a pipe 24 which passes downwardly through the housing and which discharges into the lower end of the boiler housing, or is connected to the lower end 25 of the inner coil 17. The water passes upwardly through the coil 17 to the upper end of the boiler, and with the upper end of the coil connected to a tube 26, which extends downwardly to a point 27, the return water is discharged into the housing of the boiler at a point spaced from the lower end thereof. The tube 26 may, however, be omitted and the water discharged directly into the upper part of the boiler.

The upper end of the housing is provided with an annular gas jacket 28 and a similar gas jacket 29 is positioned around the lower end of the housing.

The return tube or pipe 24 may be provided with a valve 30 to facilitate installation and repair of the boiler and similar valves 31 and 32 may be provided in the supply and return connections of the hot water coil 18.;
