UNITED STATES GEORGE DOUGLAS, OF SAN FRANCISCO, CALIFORNIA.

nonwsnrme sTovE TOP.

Application filed October 26, 1925. Serial No. 65,034.

This invention relates to a top for ra'nges oi all kinds, and its object is to provide a top that will not be subject to Warping be cause of the heating from the burner.

Another object of the invention is to provide a smooth top, one of the members of which will lit upon and overlook the next adjacent member, each member, therefore tending to support the other, and aid in preventing either from warping to the extent that connnonly takes place with such ranges Another object of the invention is to provide a top for stoves of the so called French rai'ige, or removable top type, whether burn ing gas, oil or coal, one member of which will be used as a warming plate, while the other members are used for cooking, the arrangement being such that there are two or more cooking plates, and then one warming plate aiding in supporting the one edge of each cooking plate, where only two cooking plates are used.

An embodiment of the invention is shown 7 in the accompanying drawings in which the L same reference numeral is applied to the same portion throughout, but-I am aware that there are modifications thereof:

Fig. I shows a plan View of the top of such a stove as is herein contemplated, consisting 01" two warming plates and two cooking plates; 1

Fig. 2 is a sectional viewof a portion of;

the top of the stove shown in Figure 1;

Fig. 3 is a sectional view through the burner plate on the line 33;

Fig. 4 is a sectional view cooking plate on line H.

In the first instance, a portion of the stove is shown with the top plates 1 to 4 inclusive, and a portion of a plate 5, which is sub stantially identical with the plate 2. Eaclrof the plates is provided with an exterlor groove as indicated at 6, said grooves aligning with one another to prevent grease spilled on the stove top from running ofl the edge of the stove.

It will be seen that there are four kinds of plates; the plate 1 is an end plate. The plate 2 is the plate for the burner, anolit s provided with a removable member 7 in order that the fire may be examined, or more heat obtained, whenever necessary. Plate 3 is a secondary cooking plate, while the plate 4 is a dead end plate the same as the end 1,

"of the second except that it is provided with the over-lap ledges 11. and 1.2 on its opposite edges, while the plate 5 is the same as the plate 2.

It will be seen thatthe

plates

1, 2 and 3 have over-lapping edges as indicated at 9-10, and each of the

plates

2 and 3 is provided with a series of hollow ribs as indicat ed at 8, 13, 14, 15, 16 and 17, while the plate 2 has the transverse ribs 18, 19, 20 and 21, the plate 3 having one transverse rib 22. All of these ribs are hollow, and so are each provided with an asbestos insulation to aid in preventing the ribs from warping. V

In order to provide the

members

2 and 3 with sulficient insulation surface to prevent warping, it will be seen from the construction describedabove, that each ofthe

plates

2 and 3 is provided with crossing portions which will be keptmore or. less cool by the body of the asbestos insulation, and that these cool portions will tend to hold the two plates perfectly straight.

The position of the burners, whether oil or gas, with respect to the several plates, is

indicated in Figure 2, the plate 2 already serving as a cover for the fire box.

Having thus described my invention, what 1 desire to secure by Letters Patent of the .United States, is as follows, but modifications may be made in carrying out the invention shown in the'drzrwings and in the above particularly described form thereof, within the purview of the annexed claims:

1. A cast iron cover for ranges, comprisi'ng smooth top sections having overlapping edges whereby a cover of any desired length may be built up, transverseand longitudinal hollow ribs cast on the bottom portion of said top, said hollow ribs being filled with asbestos.

2. A non-warping range top, comprising thick flat top plate sections havingoverlapping side edges, spaced longitudinal hollow, ribsintersected by spaced transverse hollow ribs, saidhollow ribs being filled with fire proof insulation.

3. A top for ranges and the like comprising a plate provided with an open ended heat insulating bore extending theret-hrough in a plane parallel with the top surface.

In testimony whereof I have hereunto set my hand this 2nd day of October A. D. 1925.

GEORGE DOUGLAS.
