at the time in the di- This invention relates to improvements in gas or electric ranges and particularly to a and other elements coincident theretoare concealed from view when a foldable and hinged cover is lowered. A further feature of the invention resides in a construction whorem the elements of safety 1s a considerat-ion, said construction being of such nature .that the cover cannot be entirely lowcred until the valves are all closed. In connection with the safety feature, the arrangement is such that should the-valves be partially closed, lowering of the cover into its extreme lowermost position automatically causes the complete closure of the several Further objects, and advantages of the present construction -will be apparent to those familiar with the stove art, upon reference to the following specification and accompanying drawings, in which:'

Fig. 1 is a front perspective view of that portion of a range embodying one form of our invention; Fig. 2 is avertical sectlon taken on the line 22 of Fig. 1, but showing in addition,

the cover lowered to conceal the valvcsand I grates.

Fig. 5 is a view similar to Figs. 2 and 4,

but illustrating the manner in which, should any of the valves be partially open, the guard plate ofthe cover will coact with the angular end portion of the valve stem to cam or force it into closed position, the

valve handle moving rection of thearrow.

Fig. 6 is a perspective ,view of the upper portion of a range embodying a modification of our invention.

Fig. 7 is an enlarged view, partly in elevation and partly in section of the front portion of the range.

Fig. 8Jis a perspective view illustrating a .novel form of valve lock, and

Fig. 9 is a sectional View on the line 9-9 of Fig. 7, illustrating the manner in which the forward portion of the hinged section of the cover rests upon the valve stems when any of the valves are open, thus visually ndicatmg 1f any of said valves are open before lowering said cover.

With particular reference to the construction shown Figs. 1v to 3, the range is designated generally by the numeral 1 and includes a top and lower oven 2 and 3 respectively, arranged at one side of the ran e, a lower side compartment 4, all closed ivy hinged doors, and .a compartment 5 above the compartment 4, the latter being adapted to contain the manifoldfi, valves 7 and mixing valves and burners 8.

For the purpose of shielding or concealing the valves manifold and parts thereof, I provide a shield 9 substantially arcuate'in cross section as shown particularly in Fig. 3, said shield extending entirely across the front of the burner compartment and being supported at its rear upper ends through the medium of integral flanges 10, which rest upon the shoulders 11 of brackets 12 suitably secured as by stove bolts 14 to the side 1grails or frame members '15 of the range 0 yp p The shield 9 is supported at its forward, lower edge by means of screws or other fastenings 16 to the upper rear edge of a cover I plate 17 which closes the compartment 5.

This shield 9 is preferably formed by casting, and durin which a series of recesses or pockets 18 s own more clearly in Fig. 2, are formed, each of said pockets having a vertical end wall 19 and a bottom wall 20, the convergent edges of which latter extend longitudinally of the shield'9 to a point where the bottom wall merges into the pllane of the upper face of said shield, the vertical wall 19 of each recess being provided with an opening 22 within which is received and operates, the stem 23 of the valve 7.

As shown in Fig. 1, there are a plurality of these valves 7, each being connected in suitable manner with the manifold 6 which lies to the rear of the shield 9. I It is one of the primary objects of this inventionto so construct the range that the cover 25 cannot be closed so long as any of the valves are open, and to this end, the valve handles 26 are so arranged, and of such length that, when they are turned to open or partially open the valves the cover cannot be entirely closed. When any one of the valve handles is in the dotted line position shown in Fig. 2, it lies in the path of movement of'the forward curved portion .27 of the cover, which preventsthe latter being entirely closed, and thereby visibly indicates to an observer that said valve or valves are not closed.

The cover 25, which is hinged at its rear edge as at 27 to the rear upper edge of the top frame 28, is provided upon each side with a flange 29 which, when the cover is closed rests upon the side members of said .top frame 28, forming thereby a substantial air circulating space above the burner grates 30, permitting cooling thereof when the burners 8 have been extinguished and the cover 25 closed. The forward portion of the cover is provided on its under side with a transverse curved guard-plate 31, attached at its upper edge to the under face of the cover by any suitable means, such as spot-welding or brazing, thelower edge being spaced away from the coverand provided with a flange 33 suitably connected with a cooperating inturned flange 31 on the lower edge of said cover, as shown in Fig. 2. The width of this flange 31 is coextensive to the flange at the upper edge of the plate 17, so that, when the cover is fully closed as shown in Fig. 2,

a smooth or flush stove front is provided free. from any obstructing flanges, ledges or otherextensions.

Should it happen that any valve or valves be left partially open. the guard-plate 31 of the cover will engage an angular end 34 of the valve handle 26 and cam it intofully closed or vertical position, asin Fig. 2.

Referring now to Figs. 6 and 7 of the drawings which represent a modification of the present invention, the body of the'range is substantially similar to that of Fig. 1. 'With particular reference to Fig.- 6, the shield 35 which covers the manifold and valves, is formed as an integral part of the upper range frame 36 which supports the usual grates 30, said shield being pro 'tutes the cover for the valve vided with the pockets or recesses 18 within which operate the valve handles 26 and stems 23. One of the particular features of the present form is that providing the cover 35 in two sections 36 and 37 hinged together at 51, the former 36' constituting, when in lowered position, the main cover, while the latter 37 in such position constihandles and associated parts. I

The section 37 of the cover, as illustrated .in Fig. 6 serves a double function :first,

that of providing a hood which will serve to catch vaporized grease arising from cooking vessels on the rear burners, and second that of'providing a shelf'which will serve such purposes as attachments of the general character are utilized. The entire cover which is hinged at 38, to the rear upper edge of the to frame 36, when closed entirely covers t e top of the range and entirely conceals every operating element,

raising and lowering of the cover being permitted by an operating handle 39. ;To the under face of the hinged section 36 is. suitably attached a brace or bracket 40, so that when the cover is in the position shown in Fig. 6, the upper hinged hood or shelf will be properly supported.

In Fig. 7 I have shown a slightly modified form of a manifold shield 41. In this arrangement, the shield is closed at its ends by plates 42, the lower rear corners of which are substantially rectangular and are seated within correspondingly shaped cutaway recesses 43 in the side plates 44 of the range. The shield is supported in the manner shown in Figs. 2 and 3 with relation to the associated stove parts, and the cover construction being substantially the sameas in Fig. 6. i

A further difference in the construction shown by this figure resides in the peculiar guard plate in transverse section. In this arrangement the outer face of the guard i plate does not describe a.true are, the greatest radius from the axis of the valve stem being substantially midway of outer edge of the end wall 19 of the recess 18, at which point it is substantially co-extensive with position, thedownwardly extending forward portion of the cover will rest on the handles,

thus indicating that a valve is open.

In Fig. 8 I have illustrated a forni of safety valve lock in which a" valve'handle 45 is provided with a spring arm '46, the

plates, as distinguished from the form shown in Figs, 1 and 2. As shown by the full line position of the valve handle 45- in Fig. 9, the forward hinged section 37 of the cover cannot be fully closed when any of the valves are. in .on position. If an attempt were made to close the cover under such conditions, the forward edge 52 of the section 37 would rest upon the valve handles and indicate that the valves were turned on.
