This invention relates to. apparatus for heating liquids, and is intended primarily for householduse, and refers to that known type of apparatus which includes a boiler.
' a. certain additionalamount of heat.
The object of the present invention is to provide apparatus for heating liquids of a generally im'provedconstruction.
Referring to the drawings tion. a
Figure 2 is a sectional view. Figure 3 is a perspective view of a part of g the apparatus shown in Figures 1 and 2.
Figure 4 is a horizontal section on line 4+4 of Figure 2.
In the construction illustrated, the boiler l is shown applied to the side of a water tank 2. This water tank 2 may be of any suitable shape, and it may either have an open top or a closed top. Further, the supply of water to the tank 2 may be governed by a float valve, or by any other means. The
V boiler may be applied directly to a liquid supply pipe. I
The arrangement is such that water is heated in the boiler 1 and passes to the'tank 2. In any arrangement the pipes maybe connected to the tank 2 so that the hot water can be taken to one or more required positions. The boiler 1 has a. cylindrical body 3 and an upwardly domed top 4..
At one side is a horizontal water inlet 5,
. member 8 having a flange 9 by which it is bolted to the flange 7 suitable jointing ma- Figure 1 is an exterior view in side eleva terial preferably being placed between the two flanges.
Further, upon the interior the boiler body 3 maybe screw threaded, as shown at 10, whilethe exterior of-the base member 8 may be similarly threaded so that the one part screws into the other.
The base member 8 is provided with a central upwardly extending flue 11 which screws into'a boss 12 in the boiler top, and if required anumber of additional flues 13 may be providedleading from the base member 8 into the flue ll. 7 V
A'gas burner 14 is placed beneath the boiler base and beneath and enclosing this gas burner is a shield 15 attached to the flanges 7 and!) by the bolts 16.
The shield 15' is provided with openings 17 so that when'condensedwate'r collects in the shield the level thereof cannot reach the upper partof the burner 14. The upper edges of the openings .17 may be pressed or disposed inwardly so as to direct any drip onto the inner surface of the shield. a
The shield 15' may be used as a support for the b'urnenthe burner tube 18 being brazed or'solclered to the tube, as shown at 19. i
[In the construction illustrated I have shown "theboiler body. and base as castings, but it is to be understood that either or both of thesepar'ts' may be made as metal pressings or stampingain which case the nec-" essary screw threads may bejrolled or "may be dispensed with, brazing or welding being employed instead of the screw joints. v j The' inlet and outlet openings 5 and 6 are connected to the tank 2 respectively [by pipes 20' and21' the pipe 21 being-arranged in inclined positionis'o that the hot water will: flow more freely into "the tank 2. 1
j The apparatus, in addition to providing a'means of obtaininga supply of hot water or other liquid, may be used for heating the wat'erin a cold water tank or pipe,'to prevent freezing at aminimum of cost and trouble. lVha-t I claim/then is 1. A liquid heating unit for application to a tank or'supply pipe, comprising an outer shell domed at its upper end 2 and "internally screw threaded and externally and circumferentially flanged at its lower end, the domed end having a central internally screw threaded hole, a body member placed in said outer shell in spaced relation thereto, said body having a recessed or upwardly domed lower end forming a combustion chamber, a vertical central tube projecting upwardly from said domed end and forming a central flue, a series of secondary tubes forming auxiliary flues, each partly vertical and partly radial, and all arranged around the central flue and each communicating at one end with the central flue and at the other end with the combustion chamber, a circumferential flange on said body, an external screw thread on said body adapted to engage the internal thread of the said shell, means for securing the flange of the shell to the flange of the body, said central tube being screw threaded at its upper end and adapted to screw into the threaded hole in the outer shell, and all of the said flues passing through the space provided between the bO( y member and the shell, an inlet and an outlet for said space between the shell and the body member, and a heating unit in said combustion chamber.
2. A liquid heating unit for application to a tank or supply pipe, comprising an outer shell domed at its upper end and internally screw threaded and externally and circumferentially flanged at its lowervend, the domed end having a central internally screw threaded hole, a body member placed in said outer shell in spaced relation thereto, said body having a recessed or upwardly domed lower end forming a combustion chamber, a vertical central tube projecting upwardly from said domed end and forming a central flue, a series of secondary tubes forming auxiliary flues, each partly vertical and partly radial, and all arranged around the central flue and each communicating at one end with the central flue and at the other end with the combustion chamber, a circumferential flange on said body, an external screw thread on said body adapted to engage the internal thread of the said shell, means for securing the flange of the shell to the flange of the body, said central tube being screw threaded at its upper end and adapted to screw into the threaded hole in the outer shell, a shield adapted to enclose the heating unit and collect the products of condensation, the shield having an opening disposed below the heating unit to prevent the products of condensation interfering with the operation of the heating unit and also serving as an inlet to the combustion chamber.
3. In a heating apparatus of the type specifled an inner body having a dished or domed plate member adapted to form the roof of the combustion chamber, a vertical central tube projecting upwardly from said domed end and forming a central flue, a series of secondary tubes forming auxiliary flues, each partly vertical and partly radial and all arranged around the central flue, and each communicating at one end with the central flue and at the other end with the combustion chamber, the said tubes formin the flues and the domed plate member all being formed integrally, and all of the said flues passing through the space provided between the body member and the shell, a circumferential flange on said body, an external screw thread on said body adjacent the said flange, and a screw thread on the upper end of said central tube.
4. A liquid heating unit for application to a tank or supply pipe, comprising an outer shell domed at its upper end, a body member placed in said outer shell in spaced relation thereto, the space between said body and outer shell forming a liquid receptacle, said body having a domed lower end forming a combustion chamber, a vertical central flue tube projecting upwardly from said combustion chamber and projecting through said outer shell, a plurality of auxiliary flue tubes connecting the central flue with the combustion chamber, the body portion together with the central main flue pipe and auxiliary flue pipes being detachable from the outer shell the outer shell having means at its upper and lower ends for connection to a tank or supply pipe and a heating unit in said combustion chamber.
In witness whereof I allix my si nature.
