ABRAM C. MOTT, JR., 013 PHILADELPHIA, PENNSYLVANIA, AND JAFEW S. VAN BUREN,

OF ALBANY, NEW YORK, ASSIGNORS T0 ABRAM COX STOVE COMPANY, OF PHILA- DELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

RANGE.

To all whom. it may concern:

Be it known that we, ABRAM C. MOTT, Jr., and JAFEW S. VAN BUREN, citizens of the United States. residing in Philadelphia,

county of Philadelphia, State of Pennsylania, and Albany, county of Albany, State of New York, respectively, have invented certain Improvements in Ranges, of which the following is aspecification.

One object of our invention is to construct a combined coal. and gas range in such a manner that the products of combustion from the fire pot of the coal sect on will pass through a combustion chainl'icr in which the gas will circulate before passing to the flucs between the top of the o en and the gas section.

A further object of the invention is to construct the range so that the gas section will extend above the top plate of the range and to confine it within the ordinary narrow limits of a coal range of the same capacity.

A still further object of the invention is to design the range so that the two flues leading around the oven of the coal section will have suflicient capacity to properly carry off the products of combustion.

In the accompanying drawings, Figure 1 is a front view of our improved range;Fig. 2 is a plan view; Fig. 3 is a longitudinal sectional view on the line (r-d, Fig. 2; Fig. 4 is a transverse sectional view on the line b I), Fig. 1; and Fig. 5 is a transverse sectional view on the line 0c, Fig. 1.

lVe have illustrated our invention as applied to a range having a base 1 and an overhead .ven 2, supported by brackets 3. It will be understood that the invention can be used with or without the overhead oven without departing from the spirit of the invention.

4 is the coal section of the range having a fire pot 5 of the normal height and arranged a given distance from the top plate.

6 is a grate of the ordinary type and 7 is the ash pit.

8 is the oven located at one side of the fire pot but arranged lower than usual. Above the oven is a combustion chamber and the upper flue 9 and at one end is the vertical flue 10 which commun cates with the upper Specification of Letters Patent.

flue and the lower flue 11 under the oven. The lower flue 11 communicates with the flue 12 at the back of the range, as indicated in Fig. i. The combustion chamber 13 com.- munieates with the fire pot 5 through the passage 13. The partition 14, which separates the lire pot from the combustion chambe! 1? (ihitblitllliled at the upper edge of the tire pot and the top plate 15 extends over the entire width of the range.

16 is an opening communicating with the ilue l1. and a damper .17 is so pivoted as to rin e eithe the opening it r the flue 12, so that tin: product of. combustion can pass directly to the chimney or indirectly around tor Ufill The oven 9 located lower than the ordinary ovenin this type of van-ge, so to bring the top of the own f substantial distance below the top of th tire pot, and a chamber 18 is formed betr ego the plate 19 having side walls and tlzn Lop plate 15 for the reception of the 95: 5 burne s. The side walls of the plate 19 prefe s iv extend to the under side of the t4 p 01511 as shown in Fig. 3. and one of tiuse alts forms one wall of the combustion I hanib-ar 13 and acts as a deflector for the pmducts ot combustion. The top plate 20 of the oven is spaced from the plate 19 to form the upper flue 9 and this plate 20 also forms the bottom of the coinl'urstion chamber 13. Thus, the products of combustion pass from the fire pot, circulate in the combustion chamber, and then pass through the flue 9 in direct contact with both plates 19 and 20.

It will be noticed that the partition wall 14 at the side of the fire pot extends considerably above the top plate 20 of the oven and preferably extends above the line of the bottom plate 19 of the chamber 18 for the gas burners so as to form an outside wall for one side of the combustion chamber 13, the other wall being formed by the side walls of the chamber. This ,construction insures the proper cin-ulation of the products of combustion in the combustion chamber before passing through the flue 9.

21-21 are the ordinary stove lids located on one-half of the top plate and mounted in the other half'of the top plate, in the present instance, i a grid 22, having openings 23 directly below which are the gas burners 24 of any desired type. The e burners are supplied with gas from pipe 25 at the front of the range and valves 26 are located in, each connecting pipe for regulating the flow of gas to the several burners.

It will be noticed that the plate 19. which separates the chamber 18 from the flue 9,

1 will be heated by, the products of combustion passing through the flue 9 and this heat is sufficient to keep hot any pots or pans which are placed on the gas portion of the range, after their contents have been brought to the boiling point, without lighting the gas. The heat from the products of combustion is sufiicient, in many instances, to keep water boiling which has previously been brought to the boiling point on the coal section when placed over the gas section when the burners are not lighted. This is an important feature of the invention. Furthermore, by depressing the chamber, as shown, we are enabled to make a range with a flat top and also by locating the chamber in the position shown, it is not necessary to extend the gas section beyond the limits of the ordinary coal range. This is particularly desirable at the present time, as a range must be of 50 a certain width to be located in the correct position in the average kitchen.

In the present instance, the overhead oven section 2 consists of a gas oven 27 and a broiling compartment 28. A gas pipe 29 leads to the burners which heat the oven and a pipe 30 leads to theburners which are used in the broiling chamber.

It will be noticed that the fire pot is at the normal height and has a fixed relation to the top plate of the range. This is essential in all ranges to obtain the best results. The oven, however, is dropped below the top of the fire pot so as to allow the chamber 18, combustion chamber 13, and the flue 9 to be located between the top plate and the top of the oven.

In the drawings, we have shown grids over the burners, but when the stove is used with natural gas then we prefer to use lids and the ordinary-cover plate and to drop the burners a sufiicient distance below the top plate so as to properly heat the top plate and the pots or pans thereon.

As before remarked, it will be understood 6 that the overhead oven section may be omitted without departing from the essential features of the invention.

We claim:
