STOVE LID Filed March l5,` 1938 Inven for williamEIullberg 56 At one side of the flre box is an Patented May 7, 1940 UNITED STATES PATENT OFFICE `Application March 15,
2 Claims.
' My invention relates to `cooking stoves. More particularly my inventionincludes an improved stove lid which is designed to increase the heating efficiency of the stove.
' One object of my invention is to improve the transfer of heat from the re box to the top of the stove and thus decrease the' amountof fuel needed to attain a desired cooking heat.
Another object is .to increase the eiective heat m; in the entire stove byslowing up the draft going toward the chimney.
Still another object is todesign a stove lid so that-heat lwill be concentrated on the lid rather than onl the stovetop surrounding the lid. A11
15 advantage of this action is the fact that in warm weather a cooking utensil on the lid can be kept at a desired temperature without heating the whole stove top kitchen.
These, and other objects are obtained primarily by means of rods which extend downwardly into the fiame area in the iire box, together with a draft deiiector or chimney cooperating with the rods.
At the present time many kitchen stoves originally designed for burning wood or coal have been equipped with oil burning heating units, known as range oil burners. Ordinarily, these stoves equipped with range oil burners are not capable of reaching the same degree of heat as they would if they were burning coal.` My invention is especially designed to improve the heating in a stove using range oil burners so that it may equal and even surpass the performance of a coal burning stove.
yTo explain 4the best mode of construction of my invention now known to me, reference will be had to the following description and the accomi panying drawing in which:
Fig. 1v is a side elevational view of a stove lid according to my invention.
Fig. 21s a bottom plan view of the same.
Fig. 3 is a perspective view showing one form ofa chimney or baille collar used with my stove lid.
45 Fig. 4 is a front elevation of a conventional type of stove `vwith parts broken away to show my stove lid in its proper position for use.
Figs. and 6 are broken views at the fitting v50- between a stove top and stove lid showing two methods vof securing the chimney or baille in proper position for use with my stove lid.
'I'he ordinary stove has a top I0 with flanged openings Il for stove lids over the fire box I2. oven I3. When and thus over-heating the 193s, serial No. 196,022
(o1. 12s-zzo) a coal or wood stove is equipped for burning oil,` the range oil burner I4 is placed in the fire box alongside the oven and spaced a distance of from about three to eight inches away from the stove top. AIf spaced too far away the heating effect on the top is lost or diminished. 1f l'placed too close to the top the burner may smoke, or the' oven alongside may fail to be heated. f
My stove lid consists of a flat top plate I5 and a plurality of closely and uniformly spaced elongated rods or prongs I6 xed to and projecting from its bottom. These rods or prongs may be cast integral with the plate or made sepa` rately and attached to the plate by pressing or butt welding. Preferably the prongs are slightly tapered so as to become heated more readily toward their tips.
I have found 4that a spacing. of about one to one and one half inches between the center of each prong produces good results, each prong at its thickest part being about three-eighths of an inch in diameter.
These prongs are made of a length to reach very close to the top of the oil burner. The best spacing seems to be within about an inch from the top of the burner or as close as possible Without interfering with the burner..` Of ycourse commercially these lids are made with different lengths of prongs so that varying levels of oil burners can be fitted.
The conventional pocket I1, for a lifting handle, is provided in the top plate.
v The plate is provided with a iiange I8 which seats the lid in the flanged opening in the top of the stove.
I have found that the beneficial effects of my improved stove lid may be greatly increased by the use of a chimney or bafe I9, one form of which is illustratedV in Figs. v3 and 6. This may consist of a sheet metal cylinder, open at both ends, with a flange 2i) for supporting the chimney in the flanged opening in the top of the stove. An alternate method of supporting the chimney I9 is illustrated in Fig. 5 where it is shown that the top of the chimney is connected by pegs or rivets 2| to the flange I8 on the bottom of the plate. In either case, the chimney can be turned in anyr desired direction so as to guide the draft to obtain the desired results.
The direction of draft depends upon the position of large holes 22 in the wall of the chimney. The same effect as the large holes may be obtained by cutting a portion of the cylinder away entirely, leaving no margin. In order to insure proper combustion, additional smaller holes 23 are provided around the top of the chimney.
The chimney l 9 is made long enough to extend along substantially the entire length of the prongs on the lid, and may be made longer Where it does not interfere with the top of the range oil burner. In order to direct the draft along the major portion of the lengths of the rods, the draft-directing holes in the Walls of the chimney are preferably made near the top, as shown. In use, the prongs on the lid, being Very close to the re, get extremely hot. Heat is conducted up the rods to `the* plate top or lid which heats much more quickly and gets much hotter than an ordinary stove lid. The presence of the closely spaced rods in the re box, immediately above the flame source, is also believed to cause a turbiiv lence in the draft which allows more time for heat to be absorbed and utilized in the stove.
The chimney further concentrates the heat on the top of the lid by conning heat radiation from the prongs. Ihe chimney also is used to guide the direction of draft. The direction of draft is from the bottom of, the chimney toward the large holes, in whatever direction they are turned. Although the holes are illustrated as being triangular, it is obvious that they may be made of any other shape.
A peculiar eiect has been observed when my invention is used With a kitchen stove equipped with a range oil burner. This is the fact that the oven temperature is increased as much as F. by using my stove lid. The vdraft may be changed by turning the chimney, still further increasing oven temperature, when desired.
This lid minimizes soot film because the prongs get so hot that soot is either burned off or heated until it ilakes and drops off. The heat of the prongs also seems to make more complete coinbustion of the fuel in the stove.
Having thus described my invention, what I claim is: Y
l. In a stove having a re box and an oven at one side of the fire box With a stove top having an opening over the re box, a stove lid assembl comprising a top plate adapted to seat in they opening, a plurality of elongated rods fixed to the bottom of the plate and extending well into the fire box, a chimney rotatably supported in said opening and surrounding said rods along substantially their entire length, said chimney having draft holes near its top, at least one of the holes being larger than the others, whereby the chimney may be rotated to direct draft either toward or away lfrom the oven.-
2.` A stove lid assemblycomprising a top plate adapted to seat in an opening of a conventional stove top, a plurality of closely spaced elongated rods projecting from the bottom of the plate and extending Well into the iire box of the stove when the top plate is seated in the said opening, a cylindrical chimney closely surrounding said rods along substantially their entire length, and draft directing means in the chimney near its top and y adjacent the bottom of the top plate.y WILLIAM E.KULLBERG.
