- To all whom it may concern:

Be it known that I, EDWARD C.BEERS, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Ranges, of which the following is a specification.

Ranges which burn solid and gaseous fuel have but a single flue under the oven bottom thru which the products of combustion pass. This flue, as at presentconstructed in many ranges, is obstructed with one or more vertical division plates, or flue strips, which are used therein to deflect, or direct, the heated gases to different parts of the flue before they reach the exit at the back of the range. These flue strips not only obstruct the flue, but form a baffle for the products of combustion and prevent their passing freely to the exit, thereby heating some spots hotter than others and thus creating an unevenly heated oven bottom.

One object of my invention is the elimination of division plates and flue strips in this flue under the oven bottom, thereby permitting the products of combustion to pass the top uninterruptedly under the whole of the oven bottom to the exit into the back flue, thus heating the bottom of the oven evenly thruout.

Another object of'my invention is to pro- Vide means whereby the uninterrupted flue under the entire oven bottom may be heated with gases from gaseous fuel.

This and other objects of my invention will be fully illustrated in the drawings, described in the specification and pointed out in the claims at the end thereof.

In the accompanying drawing:

Fig. 1 is a sectional perspective view of the range.

Fig. 2 is a detail sectional perspective view of the righthand end of the range showing the dampers arranged for burning both coal and gas for the purpose of heatin the oven.

Fig. 3 is a front elevation of the gas water heater of the range.

Fig. 4 is a sectional view of the rear of the range, the section being taken on the line 44 of Fig, 1.

In the several figures of the drawing, like reference numerals indicate like parts.

The body of the range is built with the fire box 1 from which the flue 2 leads over of the oven" At the side of the oven the divided flue 4 extends from flue PA TENT FFICE .25.

1 down below the bottom of-theoven where i it terminates in the vided flue 4 is provided with the swinging partitlon 6 which is double flue 5. The iii mounted to'swing at 7 Y in suitable bearings in the body of the range... :1-

The double flue '5 is 8 which is supported at a suitable distance below and parallel with the bottom ofthe oven 3. At the righthand end of the pardivided by the partition tition 8 is mounted the burner box 9'and vent flue 13, which form a continuation of the partition 8 and at the end of the burner box is mounted the swinging damper 10 which is adapted to burner box 9 and vent flue 13 with one side thereof and also forms an extension of the partition 8 with the other side thereof when the damper is in a horizontal position as shown in Fig. 1.

In 'the'burner box 9 is close the open top of the mounted the burner 11 which is supplied 1.

with gas thru the intake .12, leading from the outside of the range. .Thebur'nerbox 9 and vent flue 13 extend from one side of the range to the other side thereof'and the horizontal vent flue 13 is left open at either end thereof to form a vent forthe burner-11. The oven 3 is provided with the damper 14 at the upper righthand corner thereof. This damper is mounted to swing so that it can be operatedby the swinging partition 6 as will hereinafter be lower lefthandcorner of the oven 3 is mounted a second damper 15 which opens into the exit 16 hand wall of the oven and terminating in the back flue 17 at the rear of the range as shown in dotted lines in, Fig. v1. The exit 18 for the double flue-5 is provided below the partition 8 and the gases passing above thepartition thru the opening 19 at the end of the partition 8 into the lower half of the flue 5 before theypass out thru the exit 18 into the rear flue 17.

provided along the side of the leftdescribed. At the 8 must pass down When the range is operated with coal and the oven thereof is to be heated exclusively by means of the'products of combustion from the coal fire in' the fire box, the products of combustion from this fire pass thru the flue 2, over thet0p of the oven and down that directs the products of combustion over the full length of the upper half of the double flue, at the end of which they pass down the opening 19 into the lower half of the double flue 5 and then out thru the exit 18 into the rear flue 17. This path of the prod nets of combustion from the fire box 1 thru the flues 2, 4 and 5, encircles the oven 3 on three sides without obstruction thereby making close contact with the three walls of the oven. In this way the highest efficiency in the heating of the three sides of the oven, is secured. The fire box 1 which is located adjacent to the oven heats the fourth side thereof while the rear flue 1'7 heats the back of the oven.

In operating the range with coal in combination with gas for the purpose of heating the oven 8, the burner 11 is used. This burner is located in the burner box 9 and is covered by the damper 10 when coal alone is used as fuel for heating the oven, in order to prevent soot from settling thereon and keeping the holes in the burner clean. When the damper 10 is lifted from the full line position in Fig. 1 to the dotted line position thereof, the burner 11 and vent flue 13 are uncovered and the two rows of burner holes are exposed and ready to use. At the same time the lefthand end of the damper 10 makes contact with the lower end of the swinging partition 6 and in so doing, rocks the partition 6 slightly to the right. The upper end of the partition 6 is thus tilted to the left and the hip; 20 formed on the upper end of the partition 6 is forced against the damper 1 1, which damper in turn is swung inwardly into the oven by the upper end of the partition 6. In this way a portion of the divided flue 4 is closed at the top by the partition 6 and the damper 14 is opened so that a separate flue is formed which leads from the burner 11 into the upper righthand corner of the oven 3. When the damper 10 is moved into this position, the outer or righthand end thereof is moved down against the side of the burner box and in doing so opens into the lower half of the double flue 5 at the righthand end thereof, while the lefthand end of the damper 1O closes the upper half of the righthand end of the flue 5. The products of combustion from the fire box then pass down on the outside of the tilted partition 6 and the damper 10 directly into the lower half of the double flue 5 and out thru the exit 18 located in the rear of the lower half of the flue 5.

The gas burner 11 is provided with two rows of burner holes which are placed in such a manner that the righthand row directs its flame into the flue formed by the tilting of the partition 6 and part of the damper 10 as heretofore described. The products of combustion from this part of the burner pass, therefore, into the top of the oven thru the opening formed by the damperl i, heating the inside of the oven, and then pass out thru the opening formed by the damper 15 into the exit 16 and out into the rear flue 17. The burner holes in the lefthand side of the burner 11 direct their flame into the upper half of the flue 5 and they in turn pass along the full length of the bottom of the oven in an unobstructed path until they reach the opening 19 therein when these products of combustion pass down into the lower half of the flue 5 and out thru the exit 18 into the rear flue 17. The path of the products of combustion from the fire box is unobstructed by either the gas burner or the parts operated in connection therewith and the products of combustion from the gas burner 11 follow an uninterrupted course without interfering with any portion of the flue thru which the products of combustion from the coal fire pass. In this way, the products of combustion from the coal fire heat the oven independently of the products of combustion from the gas burner, and the products of combustion from the gas burner heat the oven independently from the products of combustion from the coal fire, when both the coal fire and the gas burners are 0pera-ted at the same time for the purpose of heating the oven. This is made possible by the use of the double flue 5 below the bottom of the oven with the exit 18 into the rear flue in the lower half of the flue 5 which keeps the products of combustion from the gas burner separate from the products of combustion from the fire box.

The partition 8 which divides the flue 5 serves to direct the products of combustion from either the gas burner or the coal fire over the full length of the bottom of the oven and this insures the even heating of this part of the oven. I

The gas water heater forming part of the range, comprises the shell or water front 22, which is formed by a hollow casting that is divided into an upper and a lower section by the partition plate 23. On the outside of the water front are formed theribs or fins 2a which are integral therewith. These ribs are vertically disposed on the water front and their lower end is slightly bent at an angle. Below the ribs or fins 2A: is located the gas burner 25 and the flame from this burner is directed so as to impinge against the ribs or fins and the underside of the water front. The heat generated by the gas burner 25 is then absorbed by the fins 24 which heats the water front and the water circulating therein. This makes it possible to heat the water front. by gas when the coal fire in the fire box 1 is low or even when no coal-fire is maintained in the fire box.
