JAMES H. FLAGG, 0F PERKINSVILLE, VERMONT.

SOA PSTONE STOVE.

Specification forming part of Letters Patent No. 54,319, dated May 1, 1866.

To all whom it may concern:

Be it known that I, JAMES H. FLAGG, of Perkinsville, in the county of Windsor and State of Vermont, have invented a new and useful Improvementin Stoves; and I do bereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art'to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is an elevation ot' a vertical section of a stove which contains my invention, the section being taken on the line a: of Fig. 2. Fig. 2.is a horizontal section taken on the line x ot' Fig. l. Fig. 3 is an elevation of one of the angle-irons by which the vertical joints ot' the stove are made secure. Fig. 4 isa plan or top view of one of the angleirons. Fig. 5 is a like view of an angle-iron of a'modiiied form.

Similar letters of reference indicate like parts.

This invention relates more particularly7 to stoves made of soapstone or otherl mineral substances and it consists principally in devices for making and securing the vertical joints ot' such stoves, and for securingl the panels and linings thereof, and in makin g lines and pipes out ot' soapstone.

The stove by means of which my invention is here illustrated is designated bythe letterA.

The form or principle of operation ot' the stove has no relation or connection with my invention, which is applicable to stoves of any form and construction. B designates the device by means of which the stove-panels which form the sides and linings of the stove are held in place. Its general character is that of a clasp preferably made ot' metal, which embraces the articulating edges ot` the outer panels and covers the vertical joint made by their coming together. When applied to a squareV or right-angled joint, asl here shown, its shape may likewise be as here shown. When the joint is obtuse or acute the shape of the angle-iron will be different from the shape here shown; but itis meant that the joint shall, in all cases, be covered and protected by it. Both sides of the iron are cut down, as at d, nearly to their bottom, leaving narrow strips b b, which pass beneath the outer panels G, whose lower edges are cut away for a space equal to the depth of the strips, so that the panels t over the parts b.

The letters G designate posts formed on theinner ends of the'angle-irons, and which posts may be bent outward, as seen in Fig. 4, and in the left-hand end of the stove, Fig. 2, or they mayextend straight in continuation of the direction ofthe sides of the irons. When they arel bent outward-that is, toward the right and left hand, respectively-they come against the inner faces of the panels G and serve to keep them in place. In that case the linings or inside panels come together inside of the posts, with whose flat inner sides they are in contact, the said linings being kept up against the posts by the vertical rods D, which hold the bottom and top plates to the panels. When the posts C are left to extend straight out, as in Fig. 5, their outer sides receive the ends of the linings H, which ends are beveled to tit their sides, and thus the linings are securely locked in place without any other fastening device. The space left between the faces of the posts may be lled with any suitable block or blocks. The upper and lower edges of the angle-irons, including the. edges of their posts C, are sunken into recesses or grooves made in the top and bottom plates of the stove, so that they are not liable to lateral displacement.

Another part of my invention relates to the vtlues and connecting-pipes; and it consists in making them from soapstone, either cylindrical or tapering in shape, or iiat, or of any other desired form, and of any required length'. In the example here given the said dues, designated by the letter E, are tapering and are made each from a single block of stone bored out to the size required for the diameter of the line. The blocks may, however, be shorter, so that two or more will -be required to produce a flue or pipe of' the length desired. The lue or pipe will then be composed of sections set one above another. In preparing the blocks, whether long or short, they are turned and finished on the outside and bored out in the same manner as in working wood. One Y will not retain suoli soot and dust thereon. Another advantage is derivedfroln the superior qualities of soapstone as a retainer and radiator of heat, whereby a greater uniformity can be maintained in the temperature ot' a stove, and consequently a greater degree of comfort secured to a house or room. Another advantage is the cheapness of the iiue or pipe.

I claim as new and desire to secure by Letters Patent- 1. The stove-pipe or flue bored out of a solid piece of soapstone, as and for the purposes herein described.

2. In joining the panels and plates of stoves
