Application filed March 3, 1916. Serial as. 81,967

To all whom it may concern:

Be it known that we, Hanan T. HnArs and WILLIAM luAcnaui\Y. citizens of the United States, rcsiding'at liewance. in the county of l'l'enry and State of Illinois, have invented new and useful Improvements in 1 of which the following is a specification. V

This invention relates to inu'irorements in heating devices and has particular applica tion to a liquid fuel burning submersible heater. i

In carrying out the present invention. it is our purpose to provide. a heater of the class described which may be submerged in a tank of water or other liquid to heat the same and wherein the supply of fuel to the burner may be regulated so as to accelerate or retard the heating of the water or other liquid, and wherein the productsot' combusphere, all of the heat units being extracted from the products of combustion a the latter pass to the atmosphere, thereby enabling the Water to be heated in a comparatively short time and with a minimum cousump tion of fuel.

\Vith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claim.

In the accompanying drawings; Figurenl is a view in elevation of a heater constructed'in accordance with our present invention, the same being shown immersed in a tank of water; Fig. 2 is a vertical tional viewv through the heater. Fig. 3 is a crosssectional view on the line 33 of Fig. 2. Fig. 4 is a cross sectional view on the line l-l of Fig. 2. I I

Referring now to the d 'awmg's il'l detail. 1 designates a rectangular casing: adapted to he placed in a tank" containing water or other liquid to be heated and having the top wall thereof formed adjacent to the end walls of th casing with openings and uprising from the top wall concentrically of the openings 2 respectively are fines 3 of a height suliicicnt to project above the water line of the receptacle! in which the tank is arranged. Secured the upper ends of the lines 3 are hoods l spaced apart from the upper edges of the fines to form anair space .between the hoods and the fines.

Specification of Letters Eatent.

These hoods serve toprevent the entrance of rain, etc. to the flucs, but permit the passage ofair through the fines. The can tral portion of the top wall of the rectan gular casing 1 is concave-convex as at 5 and arranged beneath the concave-convex portion of the top wall of the casing is a burner 6 and arrangedimmediately abovethe burner 6 bctween'the latter and the portion o Is a perfo'ated grate 7 designed to break up the blaze from the burner, while Patented June 2?, 331%..

encircling the burner and depending from'fh the bottom edgeyof the concaro-conrer; tion 5 is a shield 8 that acts to deflect the heat fronrthe burners; Arranged across the fiues 3, 3 respectively at the lower ends thereof are air dampers. 9 pivoted Within the respective fiues forswinging movement and connected with chains 10 that extend upwardly in the fines and have the upper ends thereof trained over the upper edges of the Hues so that the chains may be operated to open and close the dampers'so as to vary the quantity ofair passing through the lines.

The burner 6 is'of any suitable construction and is equipped with a controlling valve 11 connected through the medium. of"

suitable gearing 12 with the lower end of a, vertical shaft 13ar'an'ged in one of the dues 3 and having the upper end thereof terminating adjacent-to the upper end of the line so that the shaft may be rotated to open and close the valve.

H designates a supply tank located in some suitable position and connected by means of a pipe line 1:) with the burner 6,. the pipe line extending down through one of the fines 3.

The concavo convex portion 5 of the to wall of the casing l is preferably lined with asbestos 16 and is formed with vent holes from which lead vent pipes 17 extending upwardly from the casing and terminating above the water line of the tank in which the heater is arranged. Y a

t ll

In )llK'lI-lCO the heater is laced in the tank containing the water or other liquid fines and the vent pipes the Water may circulate between the same so as to expedite the heating of the water in the tank.

While We have herein shown and described the preferred form of our invention by Way of illustration, we wish it to be'understood that we do not limit or confine ourselves to the precise details of construction herein described and delineated, as modification and variation may be made Within the scope of the claim and without departing from the spirit of the invention.

We claim:

A heater adapted to be submerged in a tank of water or other fluid to be heated comprising a easing, air fines extending up Wardly from the casing at the respective ends thereof and terminating above the wa ter lineii the central portion of the topwall WARREN T. HEAPS. WILLIAM THA-QKERAY.
