COMBINED GAS AND COALRANGE.

Application filed July 9, 1923. Serial No. 650,287.

To all whom it may concern: v I

Be it known that I, CLARENCE V. ROBERTS, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in ,a Combined Gas and Coal Range, of which the following is aspecification.

My invention relates to certain improvements in a gas range, in which a coal section is provided so that the range can burn gas .or coal as a. fuel.

One obj set of the invention is to construct the range so that the gas supply pipe is coupled to the pipe of the range at the rear.

A further object of the invention is to shape the gas pipe so that the tray can be easily removed from under the gas section.

A still further object of the invention is to provide a special construction of burner for starting combustion in the coal section of the range.

In the accon'ipanying drawings:

Fig. 1 is a front View of my improved range;

Fig. 2 is a transverse sectional view on the line 2-2, Fig. 1;

Fig. 3 is an enlarged sectional view on the line 33, Fig. 2;

Fig. 4 is a sectional plan view on the line H, Fig. 1;

Fig. 5 is a. perspective view of a portion of the gas range showing the gas pipes; and

Fig. 6 is adetached perspective View of the kindling burner.

Referring to the drawings, 1 is the base of the range, which is mounted on legs 2, or other suitable supports, 3 is the top plateof the range having gas plates 4 and coal plates 5. The coal plates 5 are directly above the coal section 6 of the range, which has a door 7. 8 is a grate located in the coal section. 9 is a water back consisting of pipes connected to a water supply. Below the door 7 is an ash pit door 10, having a register 11 that can be turned to admit more or less air under the grate. At the opposite end of the range, is an oven 13 having a door 14. Under the oven is a broiling chamber 15 having a door 16.

17 designates a gas pipe. This gas pipe extends through the rear of the range, as shown in Fig. 2, and is threaded for the reception of any suitable coupling, which connects it with a house gas supply pipe. This pipe extends under the removable tray 18, which is supported by bracketso-n eaoh wall of the recess 19, located'between the broiling section and the coal section of the range. The pipe shaped, as shown at 20 to extend over a portion of the front of the coal section of the range, and forming a passage 21 for the freemovement of the tray 18 so that it is unnecessary to detach the pipe to remove the tray; This section of pipe 20 is preferably a casting as shown clearly in Fig. 5. The section 20 is connected to the manifold pipe 22, which is located in front of the gas section of the range. A series of pipes lead from the manifold to the burner'and valves 23 control the gas leading to said burners. A gas valve 24 controls the:

29 on the frame of the range, and is held 1 by a screw 30. On releasing the screw, the drum can be moved back to permit the burner 26 to be detached and cleaned.

The section 20 of the gas pipe has a depending extension 31, which is provided with a gas valve 32. At the front of the gas burner 26 is a regulator 33, which controls the supply of air to the mixing chamber of the burner.

The burner 26 is made as shown in Fig. 6 and is provided with an extension 34 which rests on a bracket 35 and is supported at the front by the circular enlargement 27 and is held from turning by a lug 36. The burner has a mixing chamber 37 and is perforated at 38 for the escape of gas.

' It will be seen from the above construction that only a single line of gas pipe is located at the front of the range and that the connection with the house supply is made at the back of the range. The gas pipeis shaped so that it does not interfere with the opening of the doors of the coal section of therange, or with the removal of the drip tray underthe main gas burners.

I claim:

1.- The combination in a range, of a base; a top plate spaced from the base and forming a chamber; a coal section at one side of the range between the base and the top plate; a series of burners above the chamber; a drip tray located in the chamber under the burners; a gas pipe leading from the back of the range and shaped to clear the my when the tray is withdrawn; a gas supply pipe-communicating with the said gas pipe and extending along the front of .the gas section of the range above the chamber; and a series of gas valves controlling the flow of gas from the pipe;

2'. The combination in a combinedga's and coal range,of a base; atop plate located aboveithe base; a coal section at one end of the range between the base and the top plate; an oven section at'the opposite end of iii therange; a reinovable drip tray located in tliespace' between the base and the top plate and between the coal section and the oven section; burners mounted above the drip tray; a gas pipe'in front of the range said gas pipe having valves communicating with the burner; a gas supply pipe leading from the rear of the range and in the space at one side'of the coal section; a curved section connecting the'gas supply pipe with the burner pipe and arranged to allow for the withdrawal of the tray, said connection having a depending portion provided with a valve; and a kindling burner with which the extension communicates said kindling burner being located on the side wall of the coal section. V

8. The combination-in a combined gas and coalralnge of a base; a top plate spaced from the base; a series of burners under the top plate; a pipe communicating with the burners and located at the front of the range; a supply pipe extending from the rear of therangeand communicating with the front gas pipe; an upper door and a lowerdoor on thecoal section of the range, the lower door being an ash pit door; a removable kindling burner connected with the gas supply and located at one side of the coal section and communicating therewith; and a removable drum enclosing the kindling burner.
