. Application filed February 27, 1915. Serial No. 11,096.

vented certain new and'useful Improvements 1n Stoves and Ran es; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to stoves and ranges, and more particularly that type of range in which the oven is elevated some distance above the combustion chamber,'and gets its The nature of the invention is fully dis closed in the description and claims follow ing, reference being had to the accompanying drawings, in which- Figure 1 is a front view of a device em- ,bodyingour invention; Fig. 2 is a central section of the same. Fig. 3 is a section of the same transverse to Fig. 2, showing also the application of the device to a high oven. Fig. I is a view from the under side, of the gas-burner detached. 7

Referring to Fig. 3, which shows in section an oven and connected parts of a highoven range, the numeral 1 designates the part of the combustion chamber communicating directly with the oven through a vertical fine 2. This fine at its upper end connects with the bottom of the oven 3, the products of combustion passing up and around the interior of the oven (the oven proper) and out through the smoke-pipe connection 4i, as in dicated by the arrows. As usually constructed the connection of the flue 2 with the bottom of the oven is direct, but as herein illustrated the gas-burning apparatus serves as a collar to connect said parts, as wlll more fully hereinafter appear.

In the present embodiment of the invention, which represents the preferred construction, the gas-burner 5 is in the form of an oval ring, suitably pierced at 6 for the escape of the burning gas. At each end of the oval is a hub 7 tapped for connection with a gas-pipe 8 at either end as convenience may require, the other end being suit ably; plugged at 9, as shown. From the up-'- per side of the hollow ring extends a flange; 10 adapted to be bolted to the bottom of the oven. The section of pipe 8 serves also for the admission of air, its expanded end 11- having an adjustable gate 12 for the regulation of the air supply. Into this enters the gas-jet 13, provided with a suitable cook 14:.

Instead of conneotingthe flue 2-.with a flange at the bottom of the gas ring, as

might be done, it is preferred in practice to connect the ring with a separate collar 15, which fits inside the fine in the usual way, and has an internal seat 16 to receive an annular flange 17 formed at the bottom side of the ring. The parts are connectedby bolts 18 passing through the respective parts, as shown. I

The location of the gas outlets of the burner is not of the utmost importance, but in'practice it is preferred to place them below the ring, as shown. This does not interfere with the heating action of the burner, while the position of the holes is such as to protect them from obstruction by falling soot, or the like.

The device is of special value in c0nnec-v erably from that shown, without departing from the gist of the invention, but the type illustratedis the construction preferred in practice, since it is very eflicient for gas, and

offers no obstruction to the products of com-' chambustion from the regular combustion her. when the gas is shut 01f.

Though not of primaryimportance, it is Iatented Feb. 15, 1916.;

to be noted that the gas-burner is useful also as a means for keeping the heat passages of the oven clear of soot, the independent use 1 of the gas burner tending to burn out unconsumed carbon accumulating in such passages. 7

Air to support the combustion of gas might be supplied from the combustion chamber through suitable air passages therein, but in practice it is preferred to provide the gas-burner with an air supply independent of the otheparts o1 the stove, and in close proximity to the burner. This is done by forming the collar 15 with air passages 19, which may be closed by a door 20 when the gas burner is not in use. The door is preferably mounted. on an inclined door or damper support 21 attached to the front of said. collar, and inclosing the openings therein The opening aiiords a convenient means for lighting the gas, and supplies an abundance of air for combustion;

Having thus described our invention, We claim:

1. In a stove or range having a combustion-chamber, an oven served thereby and a connecting fine, a gas-burner conforming to the cross-sectional contour of said flue, and forming. a connecting collar between the flue and the oven, presenting no interior 0bstruction to the passageof the products of combustion from the range, said collar being recessed interiorly, with gas-out-lets within said recess and opening downwardly,

whereby said outlets are protected from fall-f ingsoot, substantially as described.

2. In a stove or range having a COI1'1bIlS.-; tion. chamber, an elevated oven served thereby,- and. a connectingfiue for the products of 30 Copies of this patent may be obtained for .five cents each,,by addressing the ,Commissioner of Patents,
