ALBERT L. KLEES, OF LONG BEACH, NEW YORK, ASSIGNORTO SURFACE COMBUSTION CORPORATION, OF TOLEDO, HIO, A CORPORATION OF NEW YORK ens Bnnnme APPARATUS Application filed July 10, 1929, Serial fhis invention relates to gas burning apparatus for house heating furnaces originally designed for burning solid fuel; and has for its object to provide a gas burning apparatus of such form and construction that a' major portion thereof may be built as a unit for positioning in front of the ash pit chamber to form in efiect a lateral extension thereof from the side door opening therein, the other portion being so constructed as to permit its being positioned within the furnace; and withal to provide a gas burning apparatus which shall be efficient in operation, simple in construction and otherwise particularly well adapted for its intended purpose.

' The present application is a continuation in part of my application, Serial No. 202,833, filed July 1,1927.

The ordinary house heating furnace is provided with grates for burning solid fuel. To

install my improvedgasburning apparatus it is necessary to remove'the grates andalso the door for the ash pit chamber.

In accordance with the present invention,

there is provided a casing 10 for supplying sectional view of the 377,100. Renewed November 18, 1931.

secondary air to the burner 26 which'replaces the furnace grates. The casing extends from the door opening in the ash pit chamber 12 whereby to form in effect a lateral extension of said chamber. The admission of air into the casing is controlled by a damper 34 shown as positioned in the top wall of the casing, means being provided for opening and closing the damper at the same time that the main gas valve for the burner is opened and closed.

In the present instance, the gas valve actuating mechanism is shown as comprising a manually actuable lever 36 projecting from one side of a housing 35 wherein is contained mechanism for causing the valve to,open and close with a snap action. The lever 36 and damper 34are so interconnected, by mechanism generally indicated .at 46, that when the lever 36 is moved to actuate the gas valve 20 it will also actuate the damper, the gas valve anddamper being concurrently opened and closed as already stated.

For illustrative purposes, nism 46 is shown as comprising two link-connected bell cranks 11 and 15, the latter being connected to the damper 34 and mer to the lever 36 by a link 19. The bell crank 11 is shown as supported on a bracket- 13 extending fromthe housing 35.

The snap action mechanism comprises a the said mechathe forhead 44 secured to the stem of the gas valve in 35. A link 37 connects the' center of the sp fing 38 with the manual controlling lever 36. It will be, of course, understood that when the middle of the spring is moved past the fulcrum points 48, the outer end ofthe links 40 will move upwardly or downwardlyas the case may be, thereby actuating the 1 .valve stem, to ,close .or open the valve. Snap action mechanism of the type shown is well known in the; art.- In the present instance there is-al'so' shown associated with the head 44 a lever 48, the function of which is to prevent the gas valve from being opened I upturned extensions by hangers 53.

to provide an annular unless a thermostatic device 50, controlled by the burner pilot 47 permits.

The gas burner is of the multi-jet ringtype shown as comprising two similar sections 26 individually supplied with combustible mixture from individual mixing tubes 24 within the casing 10, the tubes delivering into individual pipes 52, which in turn deliver to the individual burner sections, the pipes having upturned extensions 54 to which the burner sections are detachably connected.'

The pipes may be supported adjacent tl i eir he burner sections are supported in any suitable manner as by lateral arms 62 projecting from a common hub removably supported on a central standard 60.

Surrounding the burner in spaced relation passage 55 is a casing 56v and spaced from the inner rim of the burner to provide an annular passage 57 is a plate 58. The casing 56 is in effect a detachable extension of the casing 10, the casing 56 being split as indicated at 56. The plate 58 is detachably supported on the standard 60. The purpose of the passages 55 and 57 is to confine and direct the secondary air, supplied by the casing 10, to flow paths immediately adjacent the burner whereby to insure proper combustion of the fuel.

In order that the hot gases from the burner may be deflected against the walls of the fire pot 68,- there is provided a bafile 66 made up of a number of wedge-shaped members 66,, the lower ends of which rest on a support 64 supported on the standard and the upper ends of which lean against the fire pot wall. A cut-out 70 in the top of each baflle member insures free escape of the spent heating gases. In order to permit a given number of baflle members to be adjusted to fire pots of different diameters, and at the same time to prevent open gaps between the members, the latter are constructed to overlap as ,shown in Fig. 7.

At the outer end of the casing 10 is a closure 14 provided with openings 22 for admitting air to the respective mixing tubes 24, the walls of the openings being extended to form tubular bosses 23 whereinto the tubes project. Associated with each tube is a jet orifice gas nozzle 27 controlled by a needle valve 32 s which is mounted in a body 28 which also forms a support for a shutter 30 for controlling the admission of air to the mixing tubes.

The nozzles 27 are mounted in the ends 26 lof conduits 16 formed in the closure 14, the

conduits having a common inlet whereinto the gas supply pipe 18 discharges. As clear- 1y shown in Fig. 5, the"wa-lls of the conduits 16 are extended into the openings 22, the end of each conduit terminating in a-tubular portion. in one end of which the nozzle 27 1s mounted and in the other end of which the body 28 is mounted.

The manufacturing and installation. advantages of the apparatus as a whole will be readily appreciated by those skilled in the art, it being noted that the casing 10: and the parts housed and supported thereby constitutes a unit which forms in effect a lateral extension of the ash pit chamber.
