'1 Claims.

This invention relates to improvements in gas stoves and ranges and more particularly to a novel and efficient shield structure for concealing and protecting the gas manifold, valves and associated stove parts.

In order to improve the appearance and promote the cleanliness and sanitation of gas stoves and ranges, the present practice has led to use of shields, aprons or extensions arranged to conceal the manifold and valves. A common difficulty with such arrangements is that the stove heat is objectionably confined by the shields, aprons or extensions, and also too readily transmitted to the shields and manifolds and valves owing to the construction of the shields and manner of connection of the shields and manifolds with the stove. Thus the manifolds, valves and shields become overheated, particularly in closed top stoves, with the result that not only is the operator likely to burn the hands in manipulating the valves, but the valves tend to stick, or leak and are often damaged.

Accordingly an object of my invention is to provide a manifold concealing and protecting arand difficulties hereinbefore noted, in a particularly eflicient manner.

Another object of my invention is to provide a shield means of the character described in which air is permitted to circulate freely beneath and behind the shield and around the manifold and valves in such manner as to prevent overheating of the manifold and valves and maintain the outer or exposed portions of the shield and valves comparatively cool.

Still another object ofv my invention is to provide a manifold concealing and shielding arrangement of the character described in which the manifold and shield are free from connection and contact with the stove top and such parts of the stove which, if connected to or engaged with, would cause the shield, manifold and associated parts to become overheated.

A further object is to provide a shield arrangement of the character described which will cause the heated air and air circulating beneath and behind the shield to pass upward into the burner chamber of the stove top and out through the vent or flue of the stove rather than confine the heat to the space beneathv the shield.

This invention further resides in the provision of a new and efficient form of shield which has a plurality of air circulating passages in an arrangement which causes a more effective air circulation around the manifold and burners and rangement which will eliminate the objections 1930, Serial No. 444,691

maintains the outer surface of the shield in a cool condition.

Another feature of the invention is the provision of a sectional shield of novel arrangement andconstruction greatly facilitating an assem- 5 bling and disassembling thereof relative to the stove and an easy adjustment of the valves.

Further, a feature of importance is a new manifold arrangement wherein the manifold is disposed below the valves and in such relation to 10 the stove top and shield as to be more effectively spaced and insulated from heat of the stove than is possible with the usual manifold disposition in gas stoves.

Yet another object is to provide a shield means 15 of the character described which is of simple and inexpensive construction, capable of being readily and easily'set up and taken down on various kinds and makes of stoves, and which disposes the valve handles in a most convenient 20 position while at the same time greatly improving the appearance of the stove.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following de- 25 scription of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and de- 30 scription may be adopted within the scope of the invention as set forth in the claims.

Referring to the drawing:

Figure l is a front elevation of a gas stove equipped with the shield of my invention.

Figure 2 is an enlarged vertical sectional view through the shield and parts of the stove.

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

The present embodiment of my invention as 40 shown in detail in the accompanying drawing forms a part of a gas stove of the closed cooking top type but it may also be effectively used in connection with open top stoves.

As here shown the stove includes a closed 45 cooking top I between which are vertical side or Wall members 2 defining with the top a burner chamber 3 for burners, a gas inlet pipe portion 4 of a burner being here indicated. The chamher 2 is open at the point where the burners extend outward for operative connection-with the gas manifold whereas at the back said chamber is vented to a flue in the usual manner, not shown.

The concealed manifold arrangement of my in- 10 a passage 1 provided beneath the top. The manivention comprises a shield structure in the general form of an elongated rectangular casing 5 detachably secured at its ends to the vertical walls 2 and disposed in front of the stove beneath the top I to conceal the manifold and valves. Upper and lower sides of the shield are open and the upper open side is disposed in spaced relation below and inwardly of a forward overhanging member 6 of the top, in position to direct air currents into the chamber through fold 8 is carried by the shield and the valves 9 'are supported on top of the manifold and connected to the burners in the usual manner. I The valve stems I project outward through orifices II in the shield and have handles I2 thereon operable on the outer side of theshield. With this arrangement it is seen that the shield is free from connection with and spaced from the cool:- ing top I. The manifold 8 is likewise free from connection with said top and spaced well below the top and outward from the front of the stove as well as spaced from opposed sides of the shield. Therefore, air will enter the lower open side of the shield and also through the space I3 between the top and shield and will pass upward and inward and around the manifold and valves through the upper open end of the shield and passage 1 into the burner chamber from whence of the shield and easy access to the valves, the

shield is of sectional construction, the upper front portion I4 being separable from the fixed section I5. The portion I 4 is arrangedto provide a rearwardly and upwardly sloping front for the shield and has the orifices or slots I I cut through to'the lower edge thereof whereby it may be readily fitted over or removed from the valve stems. The end and lower edges of the removable section I4 are provided with inwardly offset'flanges I6 arranged to rest upon lugs I! on the inner sides of the front and end walls I8 and I9 respectively of the fixed section I5.

To provide for attachment of the shield to the stove, the end walls I9 have inturned flanges 20 on their'inner vertical edges, which flanges are secured by bolts 2I to angle iron members 22 fixed to the vertical side walls 2 of the stove. The rear wall 23 of the fixed section I of the shield is upwardly and rearwardly inclined from its lower end to a point beneath the burners and then extends vertically above the plane of the end walls I9 and terminates in a baffle portion 24 spaced below the cooking top I and having an inturned horizontal flange 25 on its upper end. This portion 24 with the portion 26 of the stove "top defines the passage 1 which communicates burners extend. ,7

"To protect the manifold from the heat of the stove a bafile plate 28 is provided on the rear wall 23 and extends forward therefrom beneath the adjacent ends of the burners. In order to support the manifold on the shield without con nection of the manifold with the top I, the lower section I5 is provided on its front wall I8 with inwardly extending arms 29 on which the manifold is secured by clamps 30.

To insure an effective circulation of cooling air around the manifold and valves, a partition wall 3I is secured to the lower partof the shield in spaced substantially parallel relation to the lower part of the rear wall 23. ment a wide passage 32 is formed in the lower part of the shield between the front and partition By this arrange-.

walls, and a smaller passage 33 is defined between the partition and rear wall. The manifold lies within the upper part of the passage 32 in such position that air flowing upward through said passage is directed against and around both sides of the manifold and of course around the valves supported thereon. The bafile plate 28 is at the upper end of the passage 33 and acts to direct the air currents from said passage laterally outward against and past the manifold and valves. Thus the two air streams directed by the passages 32 and 33 to and around the manifold and valves prevent overheating of said parts and maintain them in a comparatively cool state. Furthermore, these two airpassages and the walls 23'and 3I thereof provide for an effective insulation of the outer or front wall I8 and the removable section I4, also the valve handles, and thereby maintain the front of the shield and the valve handles in a cool state to prevent burning of the hands or discomfort of a person touching the front of the shield or said handles.

It will now be clear that the concealed manifold arrangement of my invention will provide the advantages hereinbefore set forth in a particularly efiicient manner and primarily by reason of the facts that, first the shield effectively conceals the manifold, valves, etc., and improves the appearance of the stove; second, the shield is free from connection with and spaced from the stove top whereby to avoid a direct conduct of heat to the manifold, valves, etc third, the shield provides for a free air circulation about the manifold, valves and shield parts and prevents overheating of the manifold, valves and said parts, etc., as well as maintains the outer or exposed portions of the shield and valves in a 0001 state; fourth, the air circulated beneath the shield is conducted into the burner chamber 7 and passes out through the flue and therefore no heated air or heat trap is provided beneath and behind or by the shield; fifth, the manifold is free from connection with the stove top to avoid conduct of heat thereto and is supported by the shield in such manner as to effectively insulate it from the heat of the stove and thereby prevent overheating thereof and its attendant bad effects hereinbefore enumerated; and lastly, the sectional construction of the shield facilitates the assembling and disassembling thereof and provides for easy access to the valves for adjustment thereof.

It is to be noted that when the manifold arrangement of this invention is associated with an open top stove, the space I3 between the top of the shield and the stove top may serve as a vent to the atmosphere. However, with a closed top stove wherein a strong draft is created through the passage I, the tendency is for an intaking action through the passage I3 rather than a venting of the air currents through said passage.
