The outer will be Obvious that it can be applied to an elecend of each valve stem I6 has a flattened portion tric range equally Well. I9 and is slotted as indicated at 20.

The attened portions I9 of the valve tion Will be apparent from the following specistem I6 which cooperate with complementary cation and the accompanying Vdrawings forming a flattened portions in sockets 22 of the handles part thereof wherein: 2| assure the rotation of the valve stems when Fig. 1 is a front elevation of av gas cooking the handles 2| are turned. The slots 20 enable range having my invention applied thereto; the valve stem I6 to frictionally engage the walls Fig."2 is an enlarged horizontal section taken of the sockets 22 with suiiicient force to retain on the line 2 2 of Fig. 1; the handles in place upon the valve stem during Fig. 3 is a vertical section taken on the line 50 normal operation. The handles 2| are molded 3;..3 of Fig. 2; from suitable opaque plastic material and are Fig. v4 is a vertical section taken on the line preferably shaped as shown, but can be shaped4 4-4 of Fig. 2; otherwise if desired. Fig. 5 is an enlarged front elevation of vone of A cylindrical ring 30, having the outer end the indicators shown in Fig. 1; 55 thereof closed by a disc 3| which is rigidly secured in place, is disposed about the opening I8 in the escutcheon plate I2. The Valve stem I5 extends out through a central aperture 32 in the disc 3|; and the ring 30 is held against outward movement by the handle 2| which bears against the outer face of the disc 3|. The ring 30 is held against lateral movement by a pair of tongues 35 which engage in slots 36 extending out from the Vopening I8 in the escutcheon plate I2. The y -K u lower half 3'I of the disc 3| is opaque and the upper half is translucent and is divided into three sections 38, 39 and 40 which'are preferablyl of*` different contrasting colors. As shown fin'Figlr* the sections 38, 39 and 4I] may have indicia there` on to indicate whether the burner is set for low,
s'ecuredtothe-outer end of said stem, a ring of opaque-'material removably but non-rotatably securedgto the; front wall of said range between Y ,the said irontuwall and said operating handle medium or high heat. In the absence of` indicia* the contrasting color of the sections 38, 39"and" 40 Will indicate the setting of the burner as will be described. An opaque disc 4| havingr a window 42 therein is secured to the valve stem I6 for ro-V tric bulb- 46 and a switch 41, is associated with each opening I8 in position for theIbulb-S to project-'light out through the opening t8y against the back of the disc 4I.. .Thevalvestems I6 eX- tend throughV the casing 45 and are adapted to open and close the switches 41 when they are turned.fr When the valves I5 are closedthe flattened portions I3 of the valve stems I6 lie parallel to and closelyV adjacent therupper endsl of buttons48, and when .the valve stems are rotated to open the valves I5, therounded sectionsofY the stems `carnthe buttons 48 downwardly closing the switches 41 and energizing the bulbs 46'. lAsa valve stem I6 is turned to open a` valve I5 the window 42 in the disc4| is brought successively behind the translucent sections 38,V 39 andy 40 of the disc' 3|. Light from the bulb 46 will then shine through the Window 4-2 and illuminate the translucent section behind which it happens to be locatedand thus indicate whether the burner is operating at low, medium or high'iiame.
In Figs. '7, 8 and 9 I have shown aa'slightly inodiediorm of my invention. This Yform 0i the invention is very similar to the form shown in Figs. 1 to 6, the'various parts ofthe two forms-being substantiallyv the same, butar-ranged somewhat diierently with respect to each other. In this form ther disc 4|- is secured to thev` ring.v30 andl the disc 3| is rigidly secured to the valve stem .I3 directlybehind the disc 41|. The-window t2 is preferably disposed above the valve stem I6 as.. shown in Figs. 7 and S, but it may be located differently if desired. As the valvestem 'H5i is turned to open the'valve |5, theibulb .43 is ener"- gized and the translucent.sectionsv 38; 39 and 46 of the` disc 3| are successively brought upl'behind the window 412; Light yfrom thebulb will shine iirst through the translucent section and then'out through the windowf42, giving a visual'in'dicatio ofhow the burner is operating.
