JACOB SHAVOR, OF TROY, NEW YORK.

EMPPLOVEMENT IN STOVES.

To all whom it may concern:

Be it known that I, JACOB SHAVOR, of the city of Troy, county of Rensselaer, State of New York, have invented new and useful improvements upon the Stanley Goal-Burner, patented January 4,1845, and extended or renewed for a term of seven years from and after the 4th day of January, 1859; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reference being hereby had to the accompanying drawings, and to the letters of reference marked thereon, and making a part of this specification.

Like letters represent and refer to like parts.

Figure 1 is a front elevation of the wellknown Stanley vcoal-burner, patented as aforesaid. Fig. 2 is a section showing the plate b, Fig. 3, and attached thereto the cone-grateor conicalring A, the partition-plate S, the boltholes D, the air-passage E, the tube B, and the apertures t' t', through which air is admitted to the tire-chamber. Fig. 3 is a vertical section perpendicular through the center of the lower section, cone-grate, &c., from frontto rear thereof, and fully showing my improvements and the nature thereof, as hereinafter described and set forth. Fig. 4 shows the bottom plate, d, and the air passage or tube E through the same and the flues around it. Fig. 5 shows the top plate, o, oi the base, the fire-cylinder h, the .brick C, the fire-grate G, the bolt holes for the rods D, the air passage or tube E, and the plate g, whereby the said tube is constructed in connection and in combination with the cylinder h. Fig. 6 is a transverse section through the corner-fines, fire-cylinder, and fire-brick of thelower section of the said Stanley coal-burner, which parts are fully described in the said Letters Patent thereon. It also shows the air passage or tube E and the curved plate g, fire-cylinder h, and the bolts or rods D.

The nature of my improvements consists in the construction of a tube for the purpose of conducting air up the back of the iire-cylinder, and immediately between the back corneriiucs of the said coal-burner, to the tire-cham ber within said fire-cylinder and over the fire therein through the said cone-grate thereof,

which said tube is constructed in the manner as and by the combination hereinafter dcscribed and set forth.

It also consists in the mode or method of securing the upper and lower sections of the said Stanley coal-burner by the means hereinafter described, so that the members of the lower section and the members of the intermediate chamber thereof will each and all be` firmly held together, while the top section is removed from the lower section at pleasure, and each section retains its proper members, without interference with each other, during the operations of cleaning and repairing the dues, cone-grate, intermediate chamber, ,and cornice of the said coal-burner, or for the purpose of repairing any other part of said coalburner when desired. l

Having thus set forth the nature and object of my improvements, I will now give the construction thereof', to enable others to construct and use the same, which is as follows, to wit: I construct the airtube E upon the back of the recylinder h, by the use and combina tion of the circular plate g therewith, which, when done, forms an air-passage between said .plate and said fire-cylinder. This air-tube extends from the lower part of the cone-grate or conical ring A downward in connection with said fire-cylinder h, until it reaches the bottom thereof; thence a part of the said re cylinder is continued downward through the base I, and through the bottom plate, d, Fig. 3. The said curved plate g is also continued downward, in combination with said extended portion of the said lire-cylinder, until it reaches the bottom of the said plate d. There is a circular chamber, B, cast with and upon the said cone-grate A. This chamber is made to exactly correspond to the shape and to unite with'the said air-tube 'E at the top or upper end thereof. This tube is for the purpose of conducting cold air from the under side of the said coal-burner upward along the outside surface of the said fire-cylinder, whereby the said air becomes highly heated in its said passage upward, lafter which it is admitted to the iirechamber through the said cone-grate, to facilitate the consumption of the products of combustion therein. The air-passages through the said cone-grate are shownat it', and may be one or more in number.

D D, Fig. 3, are' rods connecting the plates c and b to the opposite ends of the fire-cylinder h, thereby holding the same and all parts connected therewith together by means of a head or nut and screw at the lower end thereof, and a nut and screw, c, at the upper end thereof. These rods continue upward, one at each corner of the said intermediate chamber, and through said chamber and through the plate a, which said plate is the lower plate of the said upper section. The two sections are then bolted and held rml y together by means of the nuts and screws j' upon the upper ends ,of the said rods. Vhen t-hese nuts f are removed, the said nuts e hold the lower section together, which allows the two sections to be discontinued from each other without any member or members of the same becoming disarranged, which is very desirable in mounting' said coal-burncrs-more soin cleaning and repairing the same, by which great expense in time and trouble in cleaning,` and repairing said burners is saved. rlhese two improvements constitute valuable and important fea' tures'in the said Stanley coal-burner, which make the same more useful to the public.

Having thus described my improvements, what I claim, and desire to secure by Letters Patent, is-

l. The combination of the air-tube E, the chamber `B in the conical ring or grate A, communicating with the tire-chamber by means of the apertures i, and the triangular lines, the whole being arranged and combined in the manner substantially as herein described'and set forth.

2. The method of securing the said` upper and lower sections by means of the rods D D D D, with the nuts e e e e, and upper nuts, f f ff, thereon arranged, substantially as herein described and set forth.

In testimony whereof I have, on this 24th day ot' April, 1862, hereunto set my hand.

JACOB SHAVOR.
