CURTIS RUECKERT', OF CHICAGO, ILLINOIS.

FLUID-FUEL BURNER.

Specification of Letters latent.

Patented June 17, 1919.

Application filed December 13, 1918. Serial No. 266,611.

To all whom it may concern:

Be it known that I, Gmrrrs Rnnonnn'r, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Fluid-Fuel Burner, of which the following is a specification.

The device forming the subject matter of this application is a burner adapted to be employed in connection with fluid fuel.

An object of this invention is to provide in a liquid fuel burner a means for readily and positively removing any sediment or other extraneous matter that may accumulate about its outlet or combustion orifice.

Another object of this invention is to provide a terminal valve or closure for controlling the vaporized fluid at the combustion orifice of the burner.

A further object of the invention is to provide a fluid fuel burner of generally improved construction whereby the device will be simple, durable and inexpensive in construction, as well as convenient, practical, serviceable and efficient in its use.

With the foregoing and other objects in 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 invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a perspective view of the invention;

Fig. 2 is a longitudinal sectional view of the burner tube;

Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2; and

Fig. 4 is a transverse sectional view taken on the line 44 of Fig. 2.

Referring to the drawings, there is depicted a vaporizing or generating coil, comprising aninlet arm or terminal 1 that extends horizontally from any preferred source of fuel supply (not shown). The inner or coil end of the arm 1 is bent downwardly to form a relatively short vertical arm 2 which leads to a generating or vaporizing coil formed of a plurality of horizontal convolutions 3. A generating or vaporizing arm 1 extends transversely from the terminal of the upper convolution 3 and crosses perpendicularly under the inlet arm 1. The ter minal 0f the arm a, which is remote from its juncture with the generating coil, is bent downwardly to form an outlet arm or extension 5.

A burner tube 6 is connected to the lower terminal of the arm 5 by an elbow or conpl-ing 7. This tube has a relatively large axial bore 8 that is reduced to form a shoulder 9 from which extends a relatively small bore 10. Brazed or otherwise rigidly secured to the periphery of the tube 6 is a wrench engaging member or nut 11, and an outlet or combustion orifice 12 extends radially through the wall of this tube and communicates with the large axial bore 8.

A cylindrical stem 13 is received in the bore 8, said stem having opposed portions adjacent its inner terminal cut away to form a rectangular extension 14. The opposite or outer terminal of the stem 13 is re duced to form a manipulating arm 15 that extends axially through a packing nut 16, which is threadedly secured to the outer terminal of the tube 6, and the arm 15 terminates in a manipulating eye or member 17.

Suitable packing material 18 is placed in the axial bore of the nut 16 and is held in position by a ring or washer 19, which engages the outer terminal of the tube 6 and a shoulder 20 formed at the outer terminal of the stem 13.

In operation the fuel flows under air pressure from any suitable reservoir, (not shown) through the arms 1 and 2, and generating coil 3, where it is vaporized. It then flows through the arms 4 and 5, coupling 7, and into the burner tube 6. From this point it finds its Way to the atmosphere through the bores 10 and 8, and the combustion orifice 12.

Should any sediment or other extraneous matter collect in or adhere to the bore 8 adjacent the orifice 12, this may be readily removed by rotating or oscillating the manipulating handle which causes the edges of the rectangular extension 14: to scrape against the wall of the bore 8 adjacent the orifice 12. The extension 14 may also be employed as a valve to coo erate with the orifice to control the flow 0 fuel at this point. Thus if it is desired to temporarily or momentarily discontinue the combustion of the fuel this may be accomplished by rotating the stem 13 so that its extension 1 1 will close the orifice 12, as shown in dotted lines in Fig. After a brief interval the combustion may be resumed without priming the burner, because during this interval the fuel 'has been retained in a vaporized condition in the heated coil 3.

By interposing the washer or ring 19 between the packing material 18 and the outer terminal of the stem 13, the stem 13 is held against longitudinal movement against the packing. Therefore a strong air pressure'may be employed in connection with the burner without danger of the stem 13 beiugblown or forced into the relatively soft or yielding packing material 18.

Having thus described my invention what is claimed as new is 1. A device of the class described including a. vaporizing coil having an inlet arm, an outlet arm, a burner connected with the outlet arm, said burner having a combustion orifice coinciding with the axis of theesaid coil, means for controlling the flow of fuel from the burner, a transversely disposed arm connecting the coiland outlet arm and perpendicularly crossing the inlet arm at an axial point with respect to the coil.

2. A d vice ofthe class described including a vaporizing coil, a burner tube connected with the coil, said tube having a combustion orifice, a stem rotatably mounted within the tube, a rectangular extension carried by the tube and adapted to cooperate with the combustion orifice to control the flow of fuel and to remove extraneous matter therefrom, a manipulating arm extending axially from the stem, a packing nut threadedly secured to the combustion tube, said nut having an axial bore for the reception of suitable packing material, a ring mounted on the manipulating arm between the packing material and terminal of the stem to prevent the stem from being forced .into the said packing material.

Intestimony that I claim the foregoing as my own, I have hereto affixed my signa' ture in the presence of two witnesses.
