OIL-HEATER.

1,140,?89. Specification o Letters Patent Patented May 25, 1915.

Applicationfiled September 14, 1914. Serial No. 861,709.

To all whom it may concern: inga plug 15 and a pressure gage 16. 2

Be it known that I, SCO'1T .VA 1 V1-IA' ITA a pressure within the tank 14 is maincitizen of the United States, residing at Mar fltained by means of a pump 17 of any desired ceiiusyin the county of Gas and State of construction. 60

Michigan, have invented a new-and useful Oil-Heater, of which the following'l-is a specification.- U

The device forming the subject matter of this application is a heater adapted to be,

assembled with a stove of any desired construction', the "heater preferably using kerosene or crude oil asa fuel.

An object of the present invention is to improve the construction of the flame spreader. Another object of the present invention is to improve the construction of the burner.

- A further object of the] invention is to provide a novel cooperation between the flame spreader and the burner.

It is within the scope of the invention to improve generally and to enhance theutility of devices of that type to which the present invention appertains.

With the foregoing and other objects in Interposed in the lower arm 3 of the U- shaped pipe 2 is a coupling 18 in the form of a T, and including an upstanding neck 19 supporting a cup 20. A screw plug 21 is threaded into the upper end of the section 19 and 1s provided with a lateral flange 22 which bears upon the bottom of the cup 20 tohold the-latter in plug is formed an outlet opening '23. The cup 20imay be equipped with an asbestos lining 24.

, Any desired number of burners, constructed as above described, may be mounted in the lower arm 3 of the pipe 2.

Interposed in the upper arm 5 of the pipe position. Thnpugh the 2 and located above each burner is a flame view which will appear as the description proceeds, the invention resides in the combination and'arrangement of parts and, -in' the details of construction hereinafter" described and claimed, it being understood that changes in the precise embodiment of the spreader, the same preferably comprising a cone'25 provided with lateral couplings 27 receiving constituent portions of the upper arm 5 of the U-shaped pipe 2. In the'cone' 25 is formed a V or loop-shaped, depending passage '28, the upper ends of .which' open into the couplings 27 as will "terial indicated at 29.

invention herein disclosed, can be madewithin the scope of what is claimed, without departing from the spirit of theinvention.

stove, furnace, or the like. Disposed within iIn the accompanying drawings :Figure l is aeside elevation depicting the invention, parts being broken away; and Fig. 2 is a transverse section on the line 2-2 of Fig. 1.

In the accompanying drawings, the nu meral 1 indicates a portion of the wall of a the stove or furnace-is a U-shaped pipe denoted generally by the numeral 2 and comprising anupper arm 5 and a lower arm 3, the lower arm 3 being closed at one end by a ,cap 4. The n pertarm 5 of the pipe 2 protrudes throu terminally with a valve casing 6 having a seat 7 adapted to coiiperate with a needle valve 8 actuated by means of a hand wheel 9 or in any other suitable manner. To the lower end of the valve casing 6 is attached j,

a coupling 10 united with one end of a pi e 11 which may be of any desired length, to

pipe 11 being united b means of a coupling 12 with a combined oi and air tank 14 havth wall 1 and is equipped be -und readily from the drawings.

In; this passage is disposed a filtering -mapreferably thoroughly washed gravel, ai-

thoughanother filtering material may be employed if desired.

In practical operation, a pressure is created in the oil tank 14 through the action of the pump 17. The oil tank may be located at a'considerable distance from the stove, and the danger of explosion, therefore may be reduced to a minimum. A an cient pressure may be maintained in the oil tank 14 to cause the oil to traverse the pipe 11 and pass by way of the valve casing 6 into the upper arm 5 of the *U-shaped pipe, 2.

As the oil traverses the upper arm 5', the oil descends into the depending loop-shaped passages '28 of the'flame spreaders 25 and the conversion of the oil into gas is accordingly enhanced, owing to the sinuous path which the oil is compelled to travel, it being recalled, of course, that the spreaders 25 are enveloped by flames and are in a highly heated condition. Further, as the oil traverses the depending vloop-shaped passages 28, the oil is filtered, owing to the presence of the filtering material 29. Ultimately, the gas emerges through the outlet openings 23 This material is in the burner plugs 21 and is there ignited. The cups are so constructed that each cup may hold a priining'charge to be employed initially in heating the cones or flame Spreaders 25 at the inception of the operation of the device. The plug 21 e2;- ercises a double function in that it serves to hold the cup 20 in place and serves also as a gas supplying nozzle.

vHaving thus described he invention, what is claimed is delivery pipe comprising upper and lower arms; a burner in the lower arm; and a depending conical fiame spreader in the upper arm above the burner, the flame spreader having a depending loop-shaped passage forming a continuation of the bore of the upper arm and of substantially the same cross section, as the bore cf the arm.

3.111 a device of the class described, a delivery pipe comprising upper and lower arms; a burner in. the lower arm; a depending conical flame spreader in the upper arm above the burner, said spreader having a depending loop-shaped passage forgiing a I continuation of the bore of the upper arm and of substantiallyihe same cross sectional area as the bore of the arm; and filtering material in the passage In testimonythat I claim the foregoing as my own, I have hereto afixed my signe ture in thepresence of two witnesses.
