SPECIFICATION forming part of Letters Patent No. 310,647, dated January 13, 1885.

Application filed May 28, 1884.

To all whom it may concern.-

Be it known that I, THOMAs BURKHARD, of the city and county of N ew York, in the State of New York, have invented a new and useful Improvement in Stoves, of which the following is a specification, reference being had to the accompanying drawings.

This invention is more especially applicable to stoves used by confectioners, but may be applied to stoves for other use. Confectioners7 stoves, which are subject to very rough use, commonly have the sides of the body and the base or bottom made of sheet-iron, the base or bottom plate being made of sheet-iron, because cast-iron would be cracked by the sudden cooling to which it is often subjected by pouring water into the ash-pit to cool the ashes. The sheet-iron bottom plate is commonly supported only on cast-iron feet,which are riveted to it near the margin, and almost the whole of it is left without direct support, so that it is soon bulged and broken by the severe'heat to which it is exposed.

The object of my invention is to obtain a stove the base of which is more-durable than those heretofore made of sheet-iron and than those heretofore made of cast-iron; and to this end myinvention consists in a stove-body having a sheet-iron bottom and a skeleton base of cast-iron, which gives support to the sheetiron bot-tom at or nearits center as well as near its margin, and with which the feet are integral, such construction giving great durability without materially adding to the cost of the ordinary sheet-iron-bottomed stove with feet riveted thereto.

The invention further consists in the peculiar construction of the footed skeleton base,

whereby it is made to give very efficient support to the sheet-iron bottom.

Figure l in the drawings is a central vertical section of a confectionersstove constructed according to my invention. Fig. 2 is a plan of the footed skeleton base.

Similar letters of reference indicate corresponding parts in both figures.

The body of the stove may be and is repre- (No model.)

sented as constructed, in the manner common to confectioners7 stoves, of asheet-iron cylinvs der, A, and a sheet iron bottom plate, B, united by seaming at the margin a,- and the body so constructed has the grate C and firebrick lining D applied in the usual manner.

E is the footed skeleton base, of cast-iron, which is the principal feature of my invention. This is represented as composed of a single casting, the form of which is that of a cross, the arms b b of which are united by four quadrantal braces, o c, forming a ring the circumference of which is somewhat smaller than that of the bottom plate, B. The portions of the arms b b outside of the ring c c are made with downward continuations d d in the form of feet, which,when resting upon a iioor, keep the parts b b c c raised high enough above the door. This cast-iron-footed skeleton base is riveted to the sheet-iron bottom plate by rivets e e, passing through its arms b b and the bottom plate near the margin of the latter. The support given to the bottom plate by the footed skeleton base is so distributed that the said plate is practically supported in all parts, and the open construction of the said base prevents its being cracked by sudden cooling, as is liable to occur with a solid or close base of cast-iron; and, moreover, the feet are more securely attached than when made separately and attached independently of each other, as they are all braced together.

Vhat I claim as my invention, and desire to secure by Letters Patent, isl 1. The combination, in a stove-body, of a sheet-iron bottom and a cast-iron skeleton base having integral feet, substantially as herein described.

2. The footed skeleton stove-base consisting ofthe cross b b, the ring c c, and the feet d d at the ends of the arms of the cross, substantially as herein described.

Trios. BURKHARD.
