BURNER.

Specification of Letters Patent. Patented Nov. 11, 1919.

Application filed May 1, 1917. Serial No. 165,721. 7

To all whom it may'concern:

Be it known that I, CHRISTIAN F. BECK, a citizen of the United States, residing at Steelton, in the county of Dauphin and State of Pennsylvania, have invented a new and useful Burner, of which the following is a specification.

The subject of this invention is a liquid or pulverized fuel burner, and the objects of the invention are, first, to provide means for atoniizing the fuel, second, to provide a novel and adjustable atomizing nozzle third, to provide means for forming a vacuum adjacent the nozzle to converge the atomized particles, and fourth, to produce a simple and efficient burner.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combi-' nation 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.

A practical embodiment of the invention is shown in the accompanying drawings, wherein Figure 1 is a central longitudinal section of a burner constructed in accordance with my invention.

Fig. 2 is a detail section on the line 22 of Fig. 1.

Referring to the drawing by numerals 2-- The burner comprises a fuel nozzle 1 which is a pipe with its discharge orifice reamed or beveled, as shown at 2. The discharge end is interiorly threaded to receive the thread pitched teeth formed along the edges of radially extending walls 3 which form the stem of an atomizing tip formed with a cone-like head4. The other end of the fuel nozzle 1 is formed with an outwardly extending annular flange 5 having a hub 6 on the front face thereof. The hub 6 surrounds the nozzle 1. A hollow bellshaped member 7 is provided with a central bore in its flat base or rear end 8 which is threaded to engage the threads formed on the surface of the hub 6. The curved end of the bell-shaped member 7 is apertured at 9 to permit the end of nozzle 1 to pass freely therethrough. A laterally extending hub 10 is formed on the member 7 near the bottom of said member and into this. hub a pipe may be threaded. The nozzle 1' has an end 11 extendingbeyond the flange 5 which is threaded for connection to a suitable sup- Ply P P In practice, the devlce is operated as follows ':A pipe leading from a suitable source of air or steam supply is threaded into the hub 10. A source of fuel supply is connected through suitable piping with'the end 11 of nozzle 1. Air or steam is forced through the bell-shaped member 7 and out at the annular orifice formed by the projection of the nozzle 1 through the aperture 9. This rapidly expelled tubular stream of be formed adjacentjthe exposed circular 'face of the head 4:, as indicated at 13. Be-

cause of the vacuum at 13, the expelled air or steam will be diverted from its regular course and drawn to converge toward the form of a cone. At the same time, the rush of air or steam by the nozzle tip will cause a vacuum in the nozzle which will cause fuel to be drawn from the nozzle in a thin tubular stream. This fuel will be violently drawn across the periphery of the head 4: and thoroughly atomized or broken up. The atomized fuel will be carried up the inner surface of the converging portion of the tubular stream and thoroughly mixed with the air or steam at the place of greatest convergence. This mixture may then be lighted at a point immediately beyond the place of greatest convergence.

As will be understood, the tip may be screwed in or out to a point of most efficient discharge opening.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a burner, a casing having a threaded opening formed in the bottom thereof and having an opening in the top thereof, a fuel nozzle having a threaded portion positioned in the threaded opening, and having its upper end extending through the opening in the top of the casing and terminating at a point above the upper edge thereof, the upper end of the fuel nozzle being spaced from the walls of the opening to provide an annular passage way, a tip having channel ways, positioned in the nozzle, said tip havlng a head extending beyond the upper edge of the casing, and being of a diameter equal to the exterior diameter of the nozzle, to direct a quantity of fuel into the path of travel of air discharging from the annular passage Way above the casing.

2. In a burner, a casing, a fuel nozzle extending through the casing, said casing having an opening in the upper end thereof, the upper end of said nozzle extending through the opening in spaced relation therewith, and terminating at a point above the casing, a. tip positioned Within the upper end of the fuel nozzle, said tip having channel Ways formed therein, the upper Wall of each channel Way being curved to direct a flow of fuel transversely of the tip and into the path of travel of air discharging between the casing and Wall of the opening formed in the upper end of the casing.

In testimony that I claim the foregoing as my own, I have hereto ai'hXed my signature in the presence of two Witnesses.
