TANK-HEATER.

Specification of Letters Patent.

Patented'Sept. 7, 1915.

Application filed February 1S, 1915. Serial No. 9,174.

To all w hom it mag/.concern i Be it known that I, JOHN zen ot the United States, residing at'l-lome-r,

in the county of Champaign and State of illinois, have invented certain new and-use-` iul improvements in Tank-Heaters; and I do declarethe following to be a `full, clear, and enact description or' the invention such :is will enable others skilled in the art to which it appertains to make andusethe same. A

This invention `relates to heating apparatus and more particularly to heatersin which Fluid fuel is used, designed for use in water tanks, and the object is to prevent freezing of the contents thereof. I

Another object of this invention is to provide a continual circulation of' water around the heater to further prevent any freezing of the contents of thetank, and a further object of this invention relates to means for confiningtheheat in the casing or heat chamber to develop a maximum amount of heat at a minimum expenditure of p.

the chamber 1, the cap 6 of the air inlet 2 is fuel. y

llVith the above and other vobjects in View, the invention consists ofvcertain novel features of construction, combination and arrangement of parts as will be more fully described and claimed.

ln the accompanying drawings-z Figure k1 is a side elevation of the presentk invention showing its use in connection with a tank; Fig. 2 is a central vertical longitudinal section; Fig. 3 is a vertical transverse section taken on the line 3 8 of Fig. 2; Fig. 4 is a horizontal section on the line l--t of Fig. 2; Fig. 5 is a detail section of the air inlet flue with the closure 7 partly in section, set therein; Fig. 6 is a detail perspective view of the closure.

ln describing my invention, I` shall refer to the drawing in which similar reference characters designatey corresponding parts throughout the several views, and in which 1 is a heatingy chamber comprising an oblong hollow casing with an upright vertical l inlet flue 2 at one end. rlhis flue is circular and is closed at its upper end by'an apertured hood or cap 6 which is adapted to allow a certain amount of fresh air to be fed to the fluid burners which are placed in the heating chamber 1. rIhe opposite end of the heating chamber from its inlet iiue, is apertured and a small outlet pipe 5 projects Tristan, a citi-y therethrough, runningA forward along the top of said chamber to the inlet flue and up the side of thesame, terminating at a point near its top.

Attached to the top of the inlet of the chamber 1 is an inverted substantially L- shaped water circulating hood or conduit B which is substantially U-shaped in cross section on its horizontal portion and extends from the inlet i'iue 2 past the end of the heat chamber 1. lThe lower portion of the hood B projects downwardly and inwardly until it contacts with the end of the chamber 1 at a point approximately midway between its top and bottom, at which point there is a water inletA opening 12 to allow water in the tank to flow between the heat chamber and the hood. Disposed on one side ot the heat chamber 1 at the point of contact of the torward end of the hood B and the tlue 2, is an outlet opening 11i to allow the water to flow from the hood for a purpose hereinafter to be described.

When it is desired to increase the heat in removed and a closure or stop 7 is inserted therein. This closure or stop 7 which is yadapted to slidably engage the inner walls of the flue 2v and close the same, has a handle 9 on its upper surface and its downward movement is limited by lugs or stops 8 disposed aroundthe inner walls of the iiue 2 -just above its entrance into the heat chamber 1. The outer periphery of the closure or stop 7 is notched at 10 to allow a small4 air inlet pipe l which enters the flue near the top and runs vertically down the same until it terminates in the heat chamber near the bottom thereof.

`The heaterl is spaced from the bottom of the water tank in which it is placed and adapted to be secured thereto by any preferred means, those shown by 3 in the draw- In operation, the uid burners are placed in the heating chamber 1 which soon becomes heated, thereby heating the water in the tank and causing the same to circulate. The direction of this circulation is guided by the hood B over the top and vdown one side of the heater which creates a current running up through the inlet 12 and around across the top of the heating chamber and out the inlet 14. This circulation tends to ings being a simple and effective way of accomplishing this purpose.

keep the water continually in motion in the tank and prevents any danger of the same freezing therein. f

`When it is desired to increase the heat in the chamber l, the closure or stop 7 is placed in the inlet flue 2, thereby forcing the heat in the same to the rear. rIhe air is then fed into the chamber l by the additional or auxiliary air pipe 4: which enters the flue 2' a short distance below its top and extends downwardly through the side or' the stop or closure 7 into the heating chamber.

From the foregoing, it will be seen that I have provided a very simple and effective means for carrying out the objects of this invention, the novelty and utility of which are obvious, and the efficiency and durability of which is apparent to those skilled in the art. j f

I claim as my invention :-v

l. A tank heater of the class described comprising a heating chamber, a vertical air inlet at one end of said heating chamber, an outlet pipe at the other end, and a hood having a water inlet and outlet covering the top and part of one end of said -heating chamber to guide the circulation of water created by the heatingvchamber over the same.

2. A tank heater of the class described comprising `a heating chamber, a vertical air inlet at one end and an outlet pipe at the other end, running back to the vertical inlet f 'and upward parallel therewith to a point" near its top, an inverted substantially L- shaped hood being U-shaped in cross sectionr along its horizontal portion adapted to cover the top of the heating chamber and extending past the air outlet end thereof, the downwardly extending portion of said hood projecting inwardv and engaging the end of the heating chamber, said hood having a water inlet at the bottom of the downwardly projecting portion and a water outlet at one side of the forward end of the horizontal portion substantially as described.

3. A tank heater of the class described comprising a heating chamber, a pair of vertically disposed air inlet pipes of different diameters one disposed within the other for said heating chamber, the inlet pipe havmg a larger diameter adapted to be closed and the inlet pipe having a smaller diameter beingformed with a continual free passage for air therethrough, and an outlet pipe at the outer end of said heater for the escape of the products of combustion.

4. A tank heater of the class described comprising a heating chamber, a vertical air inlet at one end of said heating chamber, lugs onthe inner surface of said air inlet near its lower end, a closure adapted t0 slide within said inlet and be held on said lugs, an additional air pipe having its upper end projecting through the side of the inlet near the top and adapted to extendi downwardly through the closure into the heating chamber'to form a continualfree passage for air'therethrough, an outlet pipe at the other end of said heating chamber running back to the vertical inlet and up parallel` therewith to apoint near its top, and a hood having a water inlet and outlet covering the top and part of one yend of said heating chamber to guide the circulation of water created by the heating chamber over the same. l

5. A tank heater of the class described comprising an L-shaped heating chamber, and an inverted substantially L-shaped hood adapted to Contact with the horizontal portion'and the outer end `of the heating chamber to guide the circulation of water created by the heating chamber over the same.

6. A tank heater of the'class described comprising an vL-shaped heating chamber, said chamber having an air inlet at its upper end, an inverted substantially L-shaped hood covering'the top of the horizontal portion and part of the outer end of said heating chamber, a water inlet and outlet for said hood, and an outlet pipe for the hot gases projecting from the outer upper end of the heating chamber and extending between the said hood and chamber to the vertical inlet and upward parallel therewith to a point near its top. f

In testimony whereof I have hereunto set -niy hand in presence of two subscribing witf nesses.
