GAS-STOVE CONSTRUCTION.

Application filed March 7, 1927. Serial No. 173,496.

This invention relates generally to gas ranges and consists of certaln novel features of construction, combinations and arrange ments of parts as willbe hereinafter more 6 fully described and particularly pointed out in the appended claims.

Heretofore the mixing tubes or manifolds of gas ranges have been supplied with gas and air at the front of such ranges. Usually the forward ends of such manifolds have been provided with closures which had 0 en ings for receiving air from the atmosp ere and had other openings that received lateral extensions of horizontally disposed gas conduits located in front of the ranges. Ordinarily such conduits were supported by hangers that projected" outwardly from the front walls of the ranges. With such constructions, the valves for the air were at the forward ends of the manifolds and the valves for controlling the supply of gas to the manifolds were mounted on the lateral extensions of-the main supplyeconduit. As a result air drafts often times caused the flames of the discharge ends of the manifolds to be extinguished, -and frequently clothing and other articles caught on the gas valves and caused such valves to be accidentally and improperly actuated. With the present invention the gas manifolds extend through the rear walls of the ranges and receive their supply of air' and gas at the rear of such ranges. With this cmstruction, the air and gas control valves are also located at the rear of the ranges but are adapted "to be convenientl operated from the front of the ranges. ence air drafts cannot eifect the supply of air to the manifolds, and the gas valves cannot accidentally be actuated or tampered with. Moreover my construction eliminates the hangars heretofore necessary to support the gas sup ly conduits. In fact gas ranges constructeci as described herein are neater in appearance and are more readily kept clean.

In the. accom anying drawings: Figure 1 is a ont elevation of a gas range embodying my invention.

Figure 2 is a top plan view thereof showing parts broken away.

Figure 3 is a vertical sectional view taken on the line 3-.-3 of Figure 2.

Figure 4 is a fragmentary vertical sectional view taken on the line 4-4 of Figure 2.

Figure 5 is a detail sectional view of a portion of one of the manifolds.

Referring now to the drawings, '1 is the front wall, 2 is the rear wall, and 3 is the open top of a gas range embodying my invention. As shown the mixing tubes or manifolds 4 are located as usual immediately below the open top 3 but in thepresent instance preferably extend through the rear wall 2 and receive the upper ends of branch pipes 5 leading from the horizontally disposed main gas supply pipe 6. As usual the open ends of the manifolds are provided with closures 7 that in turn-have openings 8 that receive the branch pi es 5, and have openings 9 for receiving air rom the atmosphere. Suitable rotary valves 10 are mounted on the rear ends of these manifolds for controlling the supply of air through the openings 9 to the manifolds, while suitable rotary valves 11 are located in the branch pipes 5 for controlling the supply of gas from the main conduit 6 to the manifolds. As shown the air valves 10 are adapted to be adjusted by hand in the usual way, but the gas valves 11 are preferably operated from the front of the range by rod 13 that are journalled in the front and rear walls 1 and 2 and are terminally secured to said valves 4 11. Any suitable means such as the handles 14 may be secured to the forward ends of theserods for actuating the same.

With this construction a conventional form of gas lighter 15 is also supplied with gas at the rear of the range. As shown a branch pipe 16 leads from the main gas supply pipe 6 through the rear wall 2 and is terminally connected to the lighter 15 which in turn .is located below the open top 3 preferably at a point approximately midway between the inner manifolds 4:- A valve 17 is located inthis branch pipe 16 to control the supply of gaslfrom the pipe 6 to the lighter and is adapted to be operated from the front -of'the range by a rod 18. As shown this red 18 is slidably mounted in the front and rear walls 1 and 2 of the range and has an offset portion 19 engageable with the lower end of the valve stem .or plunger 20 for actuating the same. If desired a bracket 21 may be secured to the inner face of the rear wall 2- to serve as an auxiliary bearing for the rod 18. Any suitable means such as a handle 22 may be secured to the forward end i of the rod 18 to actuate the same.

In use, the valves 11 and 17 at the rear of the range may be readily operated by rotating the proper handles 14 and 22 at the front of the range.

While it is believed that from the foregoing descriptionflrhe nature and advantage of my invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within. the scope of what is claimed.

What I claim as my invention is:

1. In a gas range, the combination with the front and rear walls thereof, of a substantially horizontally disposed gas supply pipe located in rear of said rear wall, a branch conduit leading from said main supply conduit through the rear wall aforesaid terminating at a point between said front and rear walls, a valve in sand branch conduit, and means for controlling said valve including a member supported by and extending through both said front and rear walls.

2. In a gas range, the combination with the frontand rear walls thereof, and an open top upon said front and rear walls, of gas manifolds located below said open top and extending through said rear wall, a main gas conduit in rear of said rear wall, branch conduits extending between said gas manifolds and main conduit and supporting the latter from the former, valves control ling the flow of gas from said main conduit to. said manifolds, said valves being in rear of the rear wall aforesaid of said range, and actuatin means for said valves including indepen ently operable means extending through a said front and rear walls. and operable from a point in advance of the front wall of said range.

3. In a gas range, the combination with the front and rear walls thereof, and an open top u on said front and rear walls, of gas mani olds located below said open top and extending through said rear wall, a main gas conduit in rear of said rear wall communicating with said manifolds, valves controlling the flow of gas from said main conduit to said manifolds, said valves being in rear of the rear wall aforesaid of said range, and a plurality of horizontally aligned valve actuating rods supported by and extending through said front and rear walls and operable from a point in advance of said front wall.

' 4. In a gas range the combination with v the front and rear walls thereof, of a substantially horizontally disposed gas supply pipe located in rear of said rear wall, a

branch conduit leading from said main supstantially horizontally disposed gas su ply" pipe located in rear of said rear wall, a branch conduit leadin from said main ,su ply conduit through t e rear wall aforesa d terminating at'a point between said front and rear walls, a valve in said branch conduit including a reciprocating plunger, and a rod slidably mounted in said front and rear walls engaging said plunger, and

adapted to actuate the same upon movement" of'said rod.

In testimony whereof I aflix my si ature.

' JOHN C. SCH NK.
