To aZl whomit may concern: i

Be it known that we, ALBERT H. Taaensna and LOUIS I-IAssmnn, both citizens of the United States, and residents of the city of New York, borough of Manhattan, in the 'county and State of New York, have 'invented a new'and Improved Stand Boiler and V ater Heater, of which the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in stand boilers and it pertains more particularly to a stand boiler of the type having a burner associated therewith for the purpose of heating water contained in the boiler.

associated with the burner, which water heating chamber is insulated from the water of lower temperature within theboiler, thus heating the water in the water-heating chamber in a more efiicientvmanner.

It is a further object of the invention to protect that portion of the circulating system which delivers the heated water to the boiler-"5. This wall isformed' a lent-ire 1'1, and said flange is-provided with-.a plu- 'rality of openings 12, by means of which the water from the boiler hasentra'nce tothe space. betweenjthe wall 9 and-the' bottom end wall 10 of'the boiler: Leading upwardly from t-h e'wall 9'there-is aipip'e 13,

and such pipe has its upper end terminating -'at a poin't'close to the top endiwall-ofi the boiler..5, as shown :at 14.

S." aced with respect to the wall there is a wall 15 secured to the wall 9 by weldin or other suitable means at the point 16.

which is filled with asbestos or other suitable heat-insulatin material 17 Projecting upwardly from this wall 15, there is a tu ular member-18, such member being of a diameter greater than the diameter of the pipe 13, and this construction rovides an intervening space which is filed with asbestos or other suitable material 19. The tubular member 18 is secured to the'upper end 14' of the circulating pipe 13, as shown at 20. n

hisconstruetion provides an intervening space .The reference character 21 designates a burner whichf may be of the gas or liquid fuel type, and said burner is placed inrjuxta- 1 position to the bottom end wall 10 of the I s5 j flame will heat the water in thesipace between'the wall 9 and the bottom en of the boiler. The water in this'space being stand boiler 5 in such a manner that its wall 10 heated circulates upwardly through the pipe the 13 and is discharged in the upper end 0 upper end of the boiler from the action of the boiler, and is displaced by the water of lower- With the above and other objects in view,

reference is had to the accompanying drawings, in which the figure is a longitudinal sectional view of a stand boiler constructed i tween the wall 15 and the wall-9, the water Referring more particularly to the drawin accordance with the present invention.

ings, the boiler is designated by the reference numeral 5, and is carried by the usual stand or su port 6. Leading into the upper end of the oiler is a pipe 7 which su lies tion to the bottom end wall 10 o the stand temperature within the boiler 5 and which i is ,fed to the'boiler 5 by means of the pipe 7. Due to the natural circulation within de-- vices of thisfcharacter, the water oflowest,

temperature isat the bottom of the boiler- By providing the asbestos filled space bewithin the heatin chamber is protected from the cooling e ect of the water of lower temperature in the lower portion of the boiler and the heating operation of the water within the heating chamber is conse.

que'ntly'more' rapid than it would be were it not for the heat insulating material. Furthermore, by providing the cheat insulating From the foregoiiig it is apparent that the present invention provides a new and improved form of water-heating boilers, which, owing to its construction, provides for quicker heating of the water and a protection against rapid cooling of the heated water during its circulation through the cooled water contained within the boiler.

\Vhile in the present instance the invention is shown as a permanent part of a stand boiler, it is obvious that the same may be made as a removable unit and attached to stand boilers or stand boiler bottoms without departing from the spirit of the inventioni WVhat is claimed is:

An attachment for stand boilers comprising an inverted dome-shaped member mount-- ed upon the bottom wall of the boiler with its side walls provided with openings and spaced with respect to the side walls of the boiler, a circulating pipe projecting upwardly from said inverted dome-shaped member, a wall supported upon the top of said dome-shaped member and in spaced relation thereto to provide an intervening chamber, a tubular extension projecting from said wall and surrounding said circulating pipe, the tubular extension being secured to the circulating pipe at the upper end thereof, the space between the circulating pipe and the tubular extension and the wall and the inverted dome-shaped member being filled with a heat-insulating material.
