Patented July 15, 18'9.

IMPROVEMENT IN `STO-VE-OVENS.
Specification forming part of Letters Patent No. 2l 7,511, dated July 15, 1879; application Jfiled May 17, 1879. t
.To all whom 'it may concern:
Be it known that I, CLARK CALDWELL, of'Philadelphia, Pennsylvania, have invented a new and useful Improvement in the Ovens of Cooking-Ranges and Cooking-Stoves, of which improvement the following is a specification.
My invention is applicable to cooking-ran ges and cooking-stoves (whether single or double) commonly known as lattop--that is to say, to ranges and stoves in which the hot air and products from the fire-box pass first over the top, then down the sides, and then under the bottom of the oven on their way to the chimney.
I make no change in the location, general form, or relative size of the oven.
A defect in ovens as heretofore made consists in the fact that the top of the oven gets too hot, while the bottom does not get hot enough, the effect being that in the preparation of viands they cook too fast on top and too slowly toward the bottom. The object of my invention is to overcome this defect.
My invention consists in making the two side plates, the back plate, and the bottom plate corrugated, and the top plate plain or iiat, as shown in the accompanying drawings, in which Figure 1 isa perspective view of my improved oveu, the door, which is of the usual construction, being removed from its hin ges; Fig. 2, a sectional elevation of the same on the lines m y of Fig. l.
I make the sides a and b, the bottom c, and back d of corrugated, cast, or sheet iron plates. The top plate, e, I make with a plain or iiat surface, all being fastened together in the usual manner.
The fire-box (not shown) is of the usual construction. Itis located at f f, Fig. 1, the firebricks or lining (not shown) coming directly against the side plate a.'
g and h are holes where boiling is done, as usual.
fi, Fig. 2, is a scraper for clearing ashes from the corrugations of the side plate b, and from the side 1iue,j, of `the oven. 1t consists of a plate scalloped on one edge, to correspond with the corrugations of -the ovens side b, and plain on its opposite edge, to t against the outside or flue plate, as shown in Fig. 2.
k, Fig. l, is the handle of the scraper-rod 7s', which rod is of length sufcient for moving the scraper from back to front and front to back ofthe flue j.
l is the bottom flue or ash-place, into which the ashes fall.
mis the stopper or door for closing the ashplace Z.
The arrows in Fig. 2 indicate the course of the hot products from the re in the firebox, showing them to pass over the top plate of the oven, down the side lue,j, into .the ilue or ash-place Z, under the bottoml plate of the oven, and thence out into the chimney, all as usual.
n is a movable shelf, of which there may be several, if required. There is no peculiarity in the form of the shelf a; but as the corrugations in the side plates a and b constitute the grooves in which the shelf slides, lthe shelf can be set higher or lower, as desired. This construction enables me to dispense with the projecting ledges usually cast on or attached to the ovens side plates for supporting the shelf.
For obvious reasons the top plate, c, tends to get hotter than the side plates a and b, bottom c, and back d; in order to counter act which tendency, and with the view of equalizing the radiation from the top, sides, back, and bottom of the oven, I make the top plate, e, plain, to keep the heating-surface of Athis `plate at its minimum, and I make the side, bottom, and back plates a, b, c, and (l corrugated, so as to increase their heatingsurfaces.
The ashes that lodge and accumulate in the corrugations of the side plate b, unless re-v moved from time to time, would act as a non- Sists of one entire piece of ofirrngated sheet- 2. The combination of the'cori*trgat'odr side iron. I make no claim to an oven having any plate b and the scalloped scraper* i, in the one or more of its sides, and also its top, ooi'- manner and for the purpose substantially as,
rugated. set forth.
