DETACHABLE PLATE FOR CONCEALED MANIFOLDS OF GAS RANGES.

Application filed May 10,

This invention relates to improvements in detachable plate for concealed manifolds of gas ranges and the present invention has relation to stoves which contain a concealed manifold having projecting handles for working the gas valves.

The present improvement is for use also in connection with a concealed manifold having attached gas valves which are also concealed, the handles for operating the gas valves projecting through the front of the range.

In the manufacture of gas ranges having a concealed manifold and concealed gas valves, much trouble has been encountered in their use by reason of the necessity of getting access to the concealed elements, for the purpose of repairing, cleaning, etc.

Heretofore in the use of a concealed manifold, gas valves and their housings, there has been no means by which the parts can be detached, adjusted or cleaned, without disconnecting the entire manifold from the stove.

In the use of my present improvement the front of the range in which the manifold, gas valves and their housings are concealed, comprises substantially a rectangular frame having its upper horizontal portion located 0 above the manifold, gas valves and their housings, and a detachable plate located below the upper portion of the rectangular frame that conceals the manifold, valves and their housings from the outside of the range.

lln carrying out my present improvement, this detachable plate comprises a "series of long vertical slots to receive the projecting handles, and also comprises a series of short vertical slots located between the handles to permit access by means of a screw driver from the outside to the usual shutter for regulating the amount of air passing to the burner manifold.

By means of this detachable plate it is only necessary to remove a screw at each end and slide the plate'downward, causing the handles to move through said slots, when access is permitted to the valves and their housings from the front of the range, thus not necessitating the removal of the whole manifold as usual, noi' necessitating the removal of an y part of the range excepting the detachable plate.

The prrsent improvement also relates to an inner shield for the manifold, the valves 1927. Serial No. 190,201[

and their housings, whereby the said parts are wholly concealed from the inside as well as the outside. The principal object in providing this shield is as a means of protection to the valves, their housings and also the manifold. This shield serves to protect the valves and their housings from the immediate heat of the burners located in the range, whereby they are not subjected to excessive heat that would cause the valves to tend to freeze or stick, and thereby make them inoperative. The present shield further protects them from the heat by being formed of a double plate having a. filling of asbestos or mineral wool, thus forming a non-conductor for the radiated heat from the burners.

Further improvements in the invention here disclosed will be explained in the description of the parts.

In the accompanying drawings:

Figure 1 is a perspective view of a gas range showing my present improvement applied thereto.

Figure 2 is a. vertical cross section through one of the handle vertical slots.

Figure 3 is a vertical sectional view some what similar to Figure 2, taken at one side of the handle slot and showing a screw driver in position for adjusting the shutter for regulating the amount of air mixed with the gas.

Figure 4 is a detached front view of the upper portion of the rectangular frame showing the detachable plate in position on the frame and the handles projecting through the slots of the said plate.

Figure 5 is a horizontal view of Figure 4; looking from the inner side, and showing the shield in position and its cooperating parts.

Figure 6 is a view looking at the rectangular frame from the inner side, the shield being removed, exposing the manifold, gas valves and their housings.

This improvement as stated, is on a gas range, such as shown in Figure 1. In this figure an ordinary conventional range is shown with my improvement attached thereto, and also used in conjunction with an oven heat regulator. In this view, 1 indicateswhat is usually referred to as the open burner construction of the range, though in this instance its top portion 2 is preferably clo ed, and 3 is the oven and broiler part of the range.

The front portion of my improvement on tively narrow vertical strip, the manifold the conventional range, comprises a rectangular frame 4, that forms a marginal construction.

In the arrangement here shown, I place the manifold 5 adjacent the upper horizontal portion 6 of the rectangular frame, and below the manifold are a series of valve housings 7 that have upwardly extending communications 8 connected with the said manifold. These housings are preferably conical in shape, as shown and the gas valves (not specifically shown) are correspondingly so shaped.

It will thus be seen that the manifold is concealed from the front of the store by the upper horizontal member 6 of the horizontal frame, and for the purpose of concealing said housings 7 and their gas valves 7 from the outer side of the range, I use an improved detachable plate 9. This plate is provided with vertical elongated slots 10 in which the handles 11 of the valves oscillate vertically for opening and closing them; the outer portion 12 of the handles are enlarged.

For the purpose of enclosing the inanifolds, valves and their housings from the inner side of the range, I provide a depending member 13 that has its end 14 located as shown. This member 13 I term a shield and it extends downward a distance substan tially to the lower portion of the detachable plate 9. This shield is so shaped as to receive interiorly, an asbestos or mineral wool filling 15, whereby it provides a non-conducting heat member, and thus shields the valve housings and valves from the direct heat of the burners in the housing 1.

By reference to Figure 2, it will be observed that a horizontal frame 16 extends across the front end of the part 1 of the range, and this member 16 extends downward as shown at 17. forming a rectangular member that is clamped in a manner to be presently described.

The manifold 5 in this improvement is supported by means of a holder 18. This hold-er 18 (of which there are two) is provided with a curved portion 19 that [its the inner side of the manifold 5 and extends around under it as shown. while its upper end 20 abuts against the under side of the member 16 and a screw 21 passes through the member 16 and into the part 21, thus serving to unite the parts together. The manifold 5 is clamped between vertically arranged members 22. placed between the manifold and the frame 6. and these members 22 are connected with the flange 17 by means of a suitable screw 23. It will be understood, of course, that the members 22 may be omitted and the manifold clamped directly between the flange 6 and the holder 18. By provid- 111g members 22 that consist of simply a relais held out of contact with the part 6, thus making a circulation of air around it.

It will be understood, of course, that gas nipples 24 communicate with the valve housings 7 and that these nipples extend inward into a gas and air mixing member or 01121111 her 25, that is connected with a manifold 26 that extends inward and is operatively connected with the burner, not shown, located in the housing 1. As is usual, the front end of this member 25 has an oscillatory shutter member 26 that is held in its adjustment by means of a screw 27. This member needs to be adjusted to get the proper mixture of air with the gas, and to carry out the idea of the present improvement, the detachable plate 9 has its upper edge provided with short slots 28 that register with openings 29 in the shield, whereby a screw driver 30 may be passed through said slot and said opening and engage the screw 27, thus enabling the shutter to be adjusted from the outside of the range structure.

In order to permit the passage of the nipples 24.- through the shield, the latter is provided with a plurality of openings 31, the openings being located in proper position for their passage.

This shield is held in position by means of screws 32 which pass through horizontat slots 33 into the holders 18.

I adapt my present improvement to be used also in connection with a heat regulator 34, by means of which gas is supplied to an oven burner (not shown), and in this event the heat regulator is connected by a suitable tube 35 to a valve having a handle 12' that is connected with the manifold the same as the other valves. This improvement is especially adapted for use in connection with the oven heat regulator.

Many ranges are fitted with a lighter. which is not here shown. In the event of an automatic lighter being used, it passes through a short vertical slot 28, thereby adapting this improvement for use with the various types of stoves. The nipple (not shown) for the automatic lighter (not shown), passes through an opening 36 made in the shield 13.

The plate 9 in the form here shown is made of cast metal, and it may .be-enameled, but I desire it understood that sheet metal may be used instead of the cast metal.

It will be observed that the detachable plate is here shown connected with the frame 4: by means of screws 4 passing therethrough, and through lips 5 that extend from the inner edge of the wall 4 of the rectangular frame.

It will be observed from the drawings and the description that in carrying out my improvement I have the frontwall of the housing for the burners, which is referred to as the open part, constructed rectangular in form. I show the rectangular portion large enough to include a door or other member 37, though that is not essential to the invention since the rectangular portion may be made of a size adapted to receive the detachable plate 9.

Also the valve is so constructed that when the handles 12 are down, the burners are turned off, and below the vertical openings 10 I placethe word Off, and also indicate which one of the burners controls the oven heat regulator.

By this improvement a concealed manifold, valve housings and valves can bereadily manufactured'and sold, and the same be adapted to be readily repaired or cleaned either by the manufacturer, dealer or user, without the necessity of removing the manifold, which is necessary in other constructions having a concealed manifold that are known to me.
