J. B. MERIAM Jan. 1, 1952 ARTICLE SUPPORT AND RELATIVELY ADJUSTABLE GAS BUR Filed Sept. 9, 1946 Patented Jan. 1, 1952 R EUFNIER ATIVELY .;..J eliheB.-.ll .ed lm MdLQh This invention relates to an improVed burner having an improved eiflciency in thensefofgasbyreason of adjustment to' the correct-distance from the bottom of the vessel or other object being heated, and whereinthe-adjusted:position-;auto matically governs the flow of gas required to support the flame best-suited toanygivenpositioni The object of the -invention i's to im rove -theefficiency of a gas-burnei by causing- -thefi urn'er volume of the flame is reduced. and 'sim ilarlyztocause the burner to movexaway fromthe ob'jeet tobe heated as the volume of the flame is in-- creased. -..;;.=;L'

Another specific object is to provide'means for moving the burner and to so ar-range the burner that'the same means may serve to" open the -gas orifice and close it to shutoff: the flow byamnvement of the burner-in the closing direction past the low flame burning pointar; Other objects will become apparent in the following .description which'relates to .the-ac'com'-'" panying 'drawings'inwhich Fig. l is a plan view of my improved burner.

Fig. 2 is a side elevation partly in section. Q

Fig. 3 is an enlarged sectional view showin the shut-01f position.

Fig. 4 is a similar enlarged sectional detail showing the full open position.

The drawings illustrate the burner associated with a support B which may correspond to a stove gridcarrying a pot or pan P. It is to be understood, however, that the object or surface to be heated may be that of the inside wall of a furnace or that of many other surfaces receiving heat, and where it is practicable to efiect relative movement between a burner and such a surface.

Describing the arrangement shown with the use of reference characters, the burner proper comprises a head portion 5 having conventional outlet openings 6 which may be arranged in the i: and" vvhicliis show'n as having an integr'a-l fitt 1 81ea ng to the burnerhead to move toward the'object to-beheated as" the 10 c W bearing porti'on-l-ll around the tu e :Many experiments have proven thati foi each 15 1946, Serial No. 695,586

Namely, the rigid fproje tion sm extendihg dtwnwardly frimthe bearing? portion IOof the movable burner, is 'engag'edby' the rounded end of a"sc'rew""32 carrying ajl i'ead 35simil'ar "to theusual valve handle! "Thisscr'ew may be threaded": through any" suitable" support 5 40' rigidly carried"'by"theburner frame or stove parts, as may be convenient.

It will be seen that as the handle 35 is turned to move the screw inwardly, the projection 30 is swung inwardly carrying the burner upwardly around the tube l5 as a pivot. Thus, in any of several positions, varying degrees of opening through the jet openings 25 and 20 result in admitting varying amounts of gas proportionally to the flame desired for a given burner position.

Further inward movement of the screw and projection 30, through which movement the flame has been progressively diminished, moved the opening 20 above the opening 25, sealing or closing the gas supply to the burner.

Thus, it will be seen that with the actuation of one burner handle, as shown, the operating screw member, the gas supply may be closed or may be opened partially or fully, as desired, and this same movement of the screw correspondingly positions the burner away from the the object being heated, as the size of the flame increases. In the drawings I have indicated a pan P above the burner on a support B.

In addition to the mechanical convenience of eifecting a burner position, corresponding to the size of the flame, by the same means which regulates the flow of gas to support that flame, definite improvements in efficiency of the burner with relation to the gas consumed are attained.

By thus varying the flame and testing the time required to raise a given amount of water a predetermined number of degrees, I have found results showing several per cent increase efiiciency in effective use of B.t.u.s in the gas fuel.

It will be seen therefore that by predetermining the position of my burner so that in its lower position where it receives maximum gas supply for the largest fiame, that flame is more effectively applied to the subject such as the vessel by reason of the distance of separation between the vessel and burner.

The openings 20 and 25 are so positioned that in the medium or level position about half of the gas supply and a corresponding sized flame is then applied to the vessel. Likewise in a somewhat raised position, the smallest fiame is most effectively used for slow heating. These results are all attained by the single adjustment simultaneously moving the burner and regulating the flow of gas to correspond to the distance between burner and the object being heated.

A further point of simplicity, above mentioned, is that an additional turn of the same screw handle moves the burner from the low flame position to the full shutoff position.

Various modifications may be made in the structure, the essence of the invention being set forth in the appended claims.

Having thus described my invention, what I claim is:

1. In a device of the character described, the combination with a support for an article to be heated, and a fixed gas supply pipe having a cylindrical portion with a gas jet opening therethrough leading from the interior of the pipe, a burner head positioned beneath the support and rigid with a mixer pipe having a journal mounting unit rigid with the mixer pipe and rotatably embracing and fitting said cylindrical portion, said journal having a jet opening adapted to be moved into registering position with the first-mentioned opening and leading into the mixer pipe, the journal having a shoulder connected therewith, an adjusting screw, and a rigidly mounting support threaded to receive the screw and positioned so that the end of the screw may engage said shoulder for moving the journal on the pipe and act to hold the burner in a given adjusted position, the location of the registering openings being such that as the burner is swung upwardly on the journal about the pipe the openings are moved out of registration shutting off flow of gas to the mixer.

2. In a device of the character described, the combination of a support for a surface to be heated, a gas supply pipe in fixed relation to said support, a burner head and mixer element communicating therewith, said mixer element including means mounted on the pipe and adapted to permit said burner head to swing toward and away from said support, registerable valve openings in the pipe and mixer portion of said element leading into the mixer when relatively moved and acting as a valve passage, a screw operated means for swinging the burner head and mixer to move the burner head toward and away from said surface and to respectively close and open the valve supply openings.

3. A gas burner head and a mixer member, a support therefor comprising a rigid gas supply pipe, said mixer member having a portion rotatably embracing said pipe, said pipe and embracing portion having openings adapted to be brought into registration when the burner is in one position and to be moved out of registration and to a closed position when the burner is in another position, a support for an object to be heated in fixed relation to said pipe, means for swinging the burner and mixer about the pipe comprising an adjusting screw and a shoulder rigid with the burner head and mixer member engaged by the screw, the positioning of said openings being such that as the burner head moves toward the support the openings are moved toward closing position, and as the burner head is lowered the openings are moved toward full registration position.
