ATTORN EY Patented Dec. 29, 1931 UNITED STATES PATENT-OFFICE THOMAS H. 'nnzanmerou, 0F srocx'romonmnonn'rn GAS BURNING ATTACHMENT non s'rovns Application filed December 26, 1929.1 Serial No. 415,401.

the above purpose which is of an extremely simple, inexpensive and efiicient nature and which is especially adapted to be quickly and easily applied to any ordinary coal'or wood burning stove or range with a minimum of work and expense and with but slight alterations having to be made to the stove in which the burner is to be mounted.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claim.

In the drawings similar characters of ref- 20 erence indicate corresponding parts in the several views:

Fig. 1 is a side elevation of my improved burner as mounted in the firebox of a coal burning range.

Fig. 2 is a top plan view of the main member of the burner partly broken out.

Referring now more particularly to the characters of reference on the drawings, the main feature of the burner structure is a cylindrical member 1 open at one end and provided at said end with a longitudinally extending flat and relatively wide lip 2 which is level with one edge of said member and preferably has its side edges diverging toward their outer ends. The opposite end of the member 1 is provided with a concentrically located and relatively small box 3 tapped to receive a nipple 4 in turnable relation thereto. The outer end of this nipple is secured'to a control cock 5 to which a pipe fitting 6 of suitable character is connected which in turn is adapted for connection to the gas supply pipe 7 Though the parts 4, 5, and 6 are of course actually separate from the burner member 1 I contemplate assembling and selling the same as a unit with the burner so as to lessen plumbing and labor costs and simplify operations when installing the burner.

The burner is adapted to be inserted into the firebox'8 of a stove or range from the front end thereof, and so as to extend half way or more into the depth of the same.

' To support the burner Imay merely cut a hole in the firebox door, but for a neater installation I preferably provide a special door 9 to take the place of the usual door and which'is provided with a collar or box 10 in which the'burner is turnably supported.

In 0 eration the as enters the burner member 1 under pressure-from the relatively small exterior piping connections, so that the pressure of the gas in the burner will be considerably reduced over what is in the supply line. The gas flows out of the inner end or mouth of the burner'where it is initially ignited by suitable means. The oxygen necessary for the combustion of the gas is supplied to the same at said inner end of the burner through the usual bottom grate 11 of the range, which of course freely communicates with the atmosphere and with the firebox. The actual point of initial combustion is on the lip 2 which not only prevents the flame from being deflected downwardly but has a tendency to throw the flame outwardly and upwardly, as will be evident. 7

When using the burner in a cooking range in which the element is disposed to one side of the firebox it is desirable When articular ly heating the oven to cause the ame to be projected more directly toward the oven than is ordinarilythe case. I therefore arrange for the burner to be turned in the collar 10 through a 90 arc, so as to place the lip 2 in a vertical position and in facing relation to the horizontal fiue 12 leading from the firebox to the oven. To thus move the burner I mount a handle 13 in connection therewith outside the door 9. The burner then turns on the nipple 4: the latter having such a length of threaded engagement with the boss 8 that there is little chance for leakage of gas at this point. In any event should looseness develop in the turnable joint no harm will be done since the shut-0E cock is outwardly of the same. To'limit the extent of rotation of the burner I preferably provide the inner periphery of the collar with a circumferential recess 14 of the necessary length which receives a lug 15 projecting outwardly from the burner, said lug being movable between the end limits of the recess. To enable the burner to be easily removed from the door and collar at any time and normally preventing the same from shifting inwardly of the firebox I may mount a removable split retaining ring 16 on the member l outwardly of the door to bear againstthe outer periphery of the collar.

From the foregoing description it will. be be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claim.

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

A gas burner comprising a hollow cylindrical burner member open at its inner end, means for turnably mounting said member at its outer end in turnable and concentric connection with a fixed supply pipe, a door through which the member projects, a collar formed with the door and turnably supporting the member adjacent its outer end, means between the collar and member for limiting the extent of rotation of the latter, and handle means on said member outwardly of the door for rotating the member.

In testimony whereof I affix my signature.

THOMAS H. FARRI NGTON.
