GAS-SAVING ATTACHMENT FOR BURNERS.

To all whom it may concern:

Be it known that I, ALBERT AoKRoN, a citizen of the United States, and residing in the city of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented or discovered new, useful,"and Improved GasSaving Attachments for Burntic purposes in many parts of the country.

Experiments conducted by Government agencies show that by moving the gas flame nearer the utensil, water coil or other object to be heated, satisfactory results can be obtained with a very short flame and a very low service pressure. 7 I

In the case of many of the gas burning appliances now installed, the raising of the burners is diflicult and expensive, and in some cases impossible.

The objectwhich I have in view is the provision of inexpensive yet eflicient means whereby the raising of theburners in such appliances will be rendered unnecessaryv while all of the beneficialresults of such alteration may be obtained at slight expense.

My improved burner attachment not only elevates the flame so that a shorter flame and a lower service pressure may-be successfully used, but I also obtain complete combustion of the fuel and an improved and uniform application of the heat.

In the accompanying drawing, Figure 1 is a top plan View of a gassaving attachment embodying the principles of'my invention; Fig. 2 is an elevation of the same shown mounted on a ring burner, the attachment being broken away in section to show construction and the burner being'indicated in dotted lines; Fig. 3 is a similar view showing a modified form of. the attachment mounted on a gas. burner having no. axial well or opening, and also showing the attachment provided witha top plate of fire- Specification of Letters Patent.

proof material; and Fig. 4 is a similar view of another modification.

The following is a detailed description of the drawings, reference being first had to Figs. 1 and 2.

A represents my improved gas-saving attachment which is preferably made of metal and may be either pressed or cast in shape; preferably cast. The attachment is mounted as shown on the ordinary gas burner of a heating appliance, such as a range or water heater. Thus I have indicated in dotted lines at B a gas burner of the ring type having an axial well or depression.

The attachment is provided with a perimetral, downwardly and outwardly inclined apron 1 whose outer edge may reston the burner to support the cap in place. The attachment is also provided with a downwardly extending axial throat 2 which'is intended to be inserted down into the central well of'the burner B to prevent the attachment from being accidentally knocked outof position. tion surrounding the upper end of the throat 2, and 4: is an annular raised portion inter-V posed between portions 1 and 3. The raised portion' l is provided with arcuate slots 5 for the upward flow of the gas flames.

At 6 Ishow in dotted lines. ports in the upper wall of the throat 2 which may be provided for the admission of air to be mixed with the burning gas ascending from the burner B.

When the gas is turned on in the burner B, it rises from the usual burner perfora-' tions and ascends through the arcuate slots 5, forming the very desirable ring'flame un- If the ports 6 are provided der the utensil.

8 is an annular horizontal porand there is available a good pressure of gas, the gas flames may pass through said ports 6 'into'the throat 2 and burn at the center of the attachment, thus heating directly the central bottom of the utensil.

In Fig. 3 I show the. throat-2 shortened to permit-the attachment being mounted on a star shaped burner C or a burner unprovided with a central well'or marked de pression.

Ialso show in Fig. 3 the use of a plate or disk D, of asbestos composition, stove clay or other fire-proof material, which fits in the space 3 and closes the upper end of the throat 2. I prefer to provide the li$k utilized in combustion.

D with a differential edge so as to engage the raised portion 4 without, however, blocking the slots 5. The disk D becomes highly heated and greatly aids in applying a uniform heat to the utensil to which the heat is being applied.

In Fig. 4 I show the throat 2 provided with a circumferential shoulder 7 which limits the downward insertion of the throat 2 in the central well of the burner B.thus holding the apron 1 above the burner B and thereby admitting air beneath said apron.

The results obtainedby the use of my improved burner attachment have been most satisfactory. The flame is broughtclose up under the utensil or water coil sothat the full heating effect of a short flame is obtained, and good results are assured even when the service pressure is very low or irregular.

All the gas issuing from the burner is The fact that the slots 5 are formed in the highest portion of the attachmentacts to facilitate the passage of the. gas flames to the point of ignition and prevents their being'pocketed or husbanded withinthe cap instead of being conveyed to the flame openings. This is pro'vedby the fact that there is no lateral escape of unburned gas so characteristic of improperly designed devices for the purposes in question.

The attachment isinexpensive and easy to apply, andis also durable.

What I desire to claim is 1 A fuel saving attachment for gas burners adapted to be superimposed on the burner and comprising a central downwardly extending cylindrical throat, an annular horizontal portion surrounding the upper end of said throat, an annular raised portion, surrounding said annular horizontal portion, and provided with gas openings, and a downwardly and outwardly inclined perimetral apron surrounding said raised portion. w

2. A fuel saving attachment for gas burners adapted to be superimposed on the burner and comprising'a central downwardly eX- tending cylindrical portion adapted to be inserted into the central well of the gas burner, an annular horizontal portion surrounding the upper end of said cylindrical portion, an annular raised portion surrounding said annular horizontal portion, and provided with gas openings, and an outwardly and downwardly inclined perimetral apron surrounding said raised portion.

3.. A fuel saving attachment for gas burners adapted to be superimposed on the burner and comprising a central downwardly extending cylindrical throat, an annular horizontal portion surrounding the upper end of said throat, an annular raised portion,

surrounding said horizontal portion, and

provided with a plurality of arcuate slots concentric with said. attachment, and a downwardlyand outwardly inclined perimetral apron surrounding said raised portion.

4. fuel saving attachment for gas burners adapted to be superimposed on the burner and comprising a central downwardly extending cylindrical portion adapted to be inserted into the central well of the gas burner, an annular horizontal portion surrounding the upper end of said cylindrical I portion, an annular raised portion surrounding said annular horizontal portion and provided. with a plurality of arcuate slots concentric with the attachment, and a downwardly and outwardly inclined perimetral apron surrounding saidraised portion.

5. A fuel saving attachment for gas burners adapted to be superimposed on the burner and characterized by a central circular depression, an annular raised portion surrounding said depression, and provided with gas openings, and a downwardly and outwardly inclined apron surrounding said raised portion.

6. A fuel saving attachment ers adapted to be superimposed on the burner and characterized by a central circular depression, an annular raised portion surrounding said depression and provided with for gas burn- I gas openings, a downwardly and outwardly inclined apron surroundmg said ralsed portion, and a cylindrical portion depending axially from said attachment 7.
