.Application led July 8,

` The invention pertains generally to cook stoves or ranges and more particularly to a cooking top of a novel and advantageous character. Y y

The primary object of the Iinvention is to provide a new and improved Cookin(1F top for liquid and gaseous fuel stoves, adapted vto provide a smooth completely closed top when desired, and having one or more openings-therein closed by a. removable cover platewith means for supporting utensils of varying sizes over the opening when the cover plate is removed.

Another object of the invention is to provide -a novel means for closing' the vburner openings in the top. I

Still another object is to provide a cooking top whereby high heating efficiency is attained. vOther objects and advantages will become apparent from the following descriptions and inA the accompanying drawings in which:

Figure 1 is a perspective View of a gas stove embodying the invention.

Fig. 2 is a plan view of the .preferred form of the invention.

Fig. 3 is a plan view of a closure for one of the cooking' apertures.

Figs. 4 and 5 are sectional views on the lines 4-4 and 5 5 respectively, of Fig. 2 looking in the direction of the arrows.

In the embodiment selected and shown herein for the purpose of illustration, 'the invention is lincorporated in a gas range of customary construction having a body G supported on suitable legs 7. The body has at one side an oven section comprising a broiler compartment 8 and a superimposed oven compartment 9 and at 'the' other side a cooking top 10 with a 4burner chamber formed beneath lit and containing a plurality of suitable burners (not'shown). A flue connection 12 maybe lprovided in the usual manner to conduct away the waste gases from the burner chamber and the oven .section. The essential features of the invention primarily reside in the construction'of the cooking top 10.

In the ordinary construction the cooking top comprises an open grid-work forming a number of spiders which are mounted over the burners. Obviously in such a construction a large amount of heat escapes through the open grid, thus lowering the heating STOVE.

closure will be flush with the upper and lower surfaces of the plate.

In the present embodiment the stove is provided `with a frame 13 having a cent-ral` opening which is positioned over the burners. `The edges of the frame about the opening are rabbeted as shown at 14, Fig. 4,y to receive and support the cooking top 10 which preferably comprises a flat level plate of a size and thickness to fit snugly in the rabbeted edges 14 ofthe frame 13 with the upper ,surface of the top substantially flush with the upper surface of the frame. Disposed about vthe cooking top are a plurality of burner openings 15 positioned so that when the top Iis mounted in the stove, an opening will be immediately above each of the burners. The burner openings are provided with a pluralityv of inwardly extending radial ribs 16 Which form a utensil supporting spider. As may be seen in Fig. 5, Vthe ribs are trapezoidal in cross section, the upper part of the rib being the narrower partv of the trapezoid. Intermediate each ib, the edge of the burner opening is cut away from the upper surface to provide an inwardly extending flange 17. Thus a cooking top is provided in which a plurality of burner openings having utensil supporting spiders therein may, if desired, be integrally formed from cast metal.

It is frequently desirable in this type of cooking top to closefone or more of the burner openings, either for the purpose of confining the heat to one opening or for providing a warming plate in which a utensil may be warmed without coming in contact with an open flame. To this end a closure plate or lid 1S is provided foreach burner opening` which is arranged to fit in the opening in such manner that the upper and lower surfaces of the closure are level witlrthe upper and lower surfaces of the cooking top. The plate 18, as shown in Fig. 3, is arranged to fit relatively snugly within the burner opening 15, and is provided ivith a plurality of radial slots 19 Which, When the plate is positioned in the opening,

receive the' ribs 16. The side edges ofthe slots are beveled downwardly to provide surfaces complementary to the side surfaces of the ribs. rihus, upon engagement ofthe ribs 16 with the slots 1 9,.a ivedging action v f iiange 2U is adapted to engage the flange 17 piojectiiiggv inwardly of the burneropening when the plate is positioned in the opening.l The plate may be suitably apertured,as at 2i, to receive a means' for removing the plate from' the top. l

By the above, described construction a cooking top has been provided which is capable ofbeing entirely closed, by .means of the snugly fitting closure plates, to providea Warming top, upon which utensils maybe ivarined orl slowly heated out of direct contact yvith the flame i Moreover, one or more of the burner openings may be opened to perinit a. utensil yto bel heated directly by the burner.`

the top, that burner opening will be partially or entirely closed thereby and in either event the remaining portions of the top will be heated by the hot gasesdeflected there across by the utensil.

Means has been provided in the present instance for insuring a more complete and etlicient heating of the more remote portions of the cooking top from any of the'burners. Since this heating is done almost entirely by the vpassing of the hot gases from the burner along` the under surface of the cool;- ing top it becomes essential that there bey no projections thereon which would tend to obstruct the free flow of the heated `gas.

In order to provide a greater heatingsur-r face on theA lower surface of the plate, a large number of small pointed studs 22 are provided thereon. The studs 22 are formed Since the spider permits the uten?. sil to rest thereon flush with the surface of the heated gases flow Without `materially hindering the free passage ofthe gases. lt will be seen therefore, since the surface to be heated is so great, and the cooking top is relatively thin, that substantially all of theheat from the gases Will be absorbed by oritransferred to the cooking topi.

rThe cooking' top as herein disclosed lends itself particularlyto a very economical construction since it may be cast in onev piece. Moreover, the closures are so formed and mounted in the burner o jeninffs that no; artr l i :i

yAlthough the invention is susceptible ofk various modifications` and alternative cny structions', I have shown and herein described in'detail the preferred embodiment but it is yto be understoodthat Ido not thereby intend to limit the invention to the specic form disclosed but int-end to cover `all modifications and alternative constructions yfalling Within the spirit and scope of the invention as expressed in the appended claim.`

l claim as myvinvention:

n A stove' top comprising, in combination, a plate having` a circular burner opening therein, a plurality of ribs formed integral lvvith the plate and extending radially into said opening, said ribs being equidist'antly spaced apart and terminating short of the axial center of the opening, 'and a lcover plate for said opening `having a plurality of radially disposed slots havingtheir outer ends terminating in the periphery of the cover plate, said'cover plate being adapted yto fit into said openingy with its upper surface flush with the upperl surface of the top plate and with said ribsl entered iny said slots, said ribs rand slotsbeing of greater Width at their lower .edges than at their upper edges whereby the ribs are adapted to engage and support the plate throughout f the Ilength, of the ribs.

In testimony whereof, I have hereunto aliXed my signature.
