1 Claim.

This is a' division of application Serial No. 558,- O15, iiled August 19, 1931, relating to Gas stoves.

The invention relates to gas stoves of the cabinet type in which a door is used for concealing the manifold and valves so that, when the stove is not in use for cooking purposes, it presents the appearance of a cabinet or table.

In stoves of this type, the door in front of the valves must be kept open during the operation of the stove in order to insure an ample supply of air to the burners and to prevent overheating of the valves. My Patent No. 1,773,754 issued August 26, v193D covers a structure which was designed to prevent closing of this door during the operation of any one of the burners. In my said Patent No. 1,773,754, the valves are rotatable on axes disposed at substantially right angles to the front wall of the stove and they coact with a valve guard on the inner face of the hinged door to prevent closing of the hinged door when any one of the valves is open.

Another type of gas valve which has been in common use for many years is known as the drop handle valve which has a handle pivoted on an axis disposed substantially parallel to the manifold and front wall.

The main objects of this invention are to provide a gas stove having valves provided with drop handles arranged so as to be adapted to project through the opening in the front wall of the stove to prevent closing of the burner box door when any one of the valves is open.

An illustrative embodiment of this invention is shown in the accompanying drawing, wherein:-

Figure 1 is a fragmentary perspective of a cabinet gas stove to which this invention is applied.

Fig. 2 is an enlarged transverse section of the burner box showing the hinged cover and burner box door in open positions; one of the ,valve handles being shown in fully open position projecting through the front opening of the burner box. r f

Fig. 3 is a detail in section, showing one of the gas valve handles in partly open position and obstructing the closing of the door.

Inasmuch as this invention is applicable to gas stoves of many diiferent designsthe accompanying drawing illustrates only certain portions of the stove structure.

In the form shown, the stove comprises a frame l having the usual burner top 2, cast metal front wall 3, and sheet metal walls 4 and 5. A cover 6 is provided for concealing the burner top and also to serve as a table top when the stove is not a'hinge 7, so as to permit the cover to be shifted 50 to vertical position to serve as a splasher plate when the stove is in use.

Located below the burner top, are the usual gas burners 8 supplied with gas by a manifold 9.

iIhe supply of fuel is controlled by valves 10 6 suspended from the manifold and provided with handles 11 which are pivoted on a horizontal axis disposed substantially parallel to the manifold 9 and front wall 3. These valves are arranged so as to be closed when the handles extend downwardly andvto be open when the handles project forwardly.

Located below the burners, is a drip pan 12 which is slidably mounted on a pair of horizontal rails 13, so as to be adapted to be moved through an opening 14 in the front wall of the stove. The valve handles 11 are of suicient v length and are suiciently close to the front Wall 3 so that, when they are open, they project into 80 the opening 14 of the burner box.

Mounted in the opening 14, is a guard or door 15 which is adapted to close said opening for concealing the manifold, valves, and drip pan. This door is hinged to the frame by a pair of screws 16 which are threaded in lugs 17 mounted 85 tact with the flames during the operation of the stove. When the valves are only slightly open, the valve handles may not project forwardly far enoughto resist closing of the burner box door. For this reason, the inner face kof the door is provided with a transversely disposed rib 20 adapted to coact with the valve handles to resist closing of the door.

When the stove is not in use for cooking purposes, the burner box cover and front door are closed as shown in Fig. 1. in operation, the cover and door are both open as shown in Fig. 2. When any one of the gas valves is open, its handle projects forwardly to serve as a stop for resisting closing of the burner box door.` With this construction, the burners When the stove is 10 Cil always receive an ample supply of air through the opening 14 during the' operation of the stove as fully set forth in my above mentioned Feftent No. 1,773,754.

I claim:

In a gas range, a range body having a burner' top, an upper Compartment, a f-folt frame for said compartment, a manifold valves Within Leeogeee
