Letters Patent No. 86,578, dated February 2, 1869.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, CLEMENT OLHABER, of Oincin-,

nati, Hamilton county, Ohio, have invented a new and useful Improvement in Cooking-Stoves; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompan'ying drawings, making part of this specification.

The first part of my invention relates to a construction of the long-centres of a cook-stove, which obviates the liability to warping or sagging, to which such plates are now liable.

The second part 'of my invention relates to a' pro-- my invention, portions being broken away to expose the operating parts.

Figure 2 is a transverse section through a portion of the stove.

Figure 3 represents. the two'portions of the longcentre and their supporting-post detached.

I Figure 4 is a side elevation of the post and one portion of the long-centre. I fi Figure 5 is a horizontal section at the line X-X,

I form the plate commonly called the long-centre in two parts, A A, whose outer ends rest in the cns tomary rebates B, and whose inner ends are supported upon a foot or standard, 0, which rises from the top oven-plate D. V

This post may have therepresented X-formed transverse section, of such dimensions as to fit and occupy the recess between the customary stiffening-flanges a of the long-centre. a

The common long-centre in one piece is, it is well known, liable to expand on its under side by the action of the heat, causing it to sag or belly downward in the middle, so as to encroach upon the upper flue-space, and by throwing the short-centres and their lids out of their proper plane, to make the stove-top leaky, and unfit to support the vessels; and attempts to support the long-centre at its mid-length have but aggravated the evil, by preventing the up-curved ends of the plate from resting upon their rebates.

I remove the above diificulties by the simple remedy of dividing the long-centre athwart at its mid-length, and supporting said divided portions upon the post 0,

in the manner represented.

The comparative shortness and stifiness of the two pieces, A A, protect them from any deleterious sagging or departure from their proper plane.

The oven-door or doors E, instead of being attached to the jamb by the customary hinge, occupy upper and lower slides, F F, on the jamb G, and each door is provided near its mid-length, both at top and bottom, with an inclined projection or wedge, H, which, when the door is shut, binds against a similar Wedge-like protuberance, I, upon the slide, and serves to press and hold the door snugly against the jamb, so as to completely close the oven.

All sliding stove-doors have necessarily very free movement, because a change of temperatnre in the stove would otherwise cause them to. jam, and the aforesaid provision of oblique bindingsurfaces, se-

cures the effectual closure of the oven when the doors are shut, and yet permits the doors to be fitted quite loosely in their slides, so as to possess entire freedom of motion the instant that the door is released from the wedging-surfaces.

All the .aboveslides, F F, may be secured to the jambs by suitable screw-bolts K, or portions of them, where not convenient to apply bolts, may be held to the jamb by means of hooks L, which, projecting from the jamb, may engage in slotsMin the slide, and bind posite side.

I have selected, for illustration, the preferred forms .of my improvement, but reserve the right to vary the same. For example, a pin, stud, or eccentric, might replace the inclined projection, either on the door or.
