HOT-AIR FURNACE.
The Schedule referred to in these Letters Patent and making part of the same To whom it may concern Be it known that I, Moses A. THAYER, of the city of Chicago, in the county of Cook and State of Illinois, have invented-certain new and useful Improvements in Hot-Air Furnaces; and f I do herebydeclare that the following is a full and exact description of ,the same,'reference being had tothe accompanying drawings and to the figures and letters of reference marked thereon, forming a part of this specification, in which Figure l is a'vertical section,

tubes through 2 c of fig. 3.
The nature and object of my invention is to construct a hot-air furnace in as cheap and practical a way as possible, and one that-will turn to. a practical account as much of the heat as possible generated from the fuel.-
To enable others skilled in the art to makeand use my invention, I willprocecd to describe its construction Similar letters of reference in the. different drawings refer to similar parts.
*In fig. 1 will be seen the internal arrangement of my furnace, in which it will be observed that my invention is of that class called base-burners.
ais the coal-chamber, wherein isplaced the coal for consumption. r
c c c are the hot-air tubes. I
b is a deflector extending from thecoal-chamber a to the tubes 0 c.
d is the space around the air-tubes or pipes c c c.
m is the ash-pit.
f is an inner circular grate, provided with an edged or toothed surface, as seen in fig. 2.
g is an outer grate surrounding the inner grate f, as seen in fig. 2, with its inner edge toothed or notched similar to theouter edged the inner circular grate.
w is a pivot supporting the inner plate f andu'est ing upon the revolving bar It It, fig. 2.
h is a lever, resting and working upon the fulcrum" c, which fulcrum restsiupon an arm, a, extending'from the revolving bar k k.
l is a pin extending down from the inner circular grate f and through a slot inthelever-h.
q are two pins extending down from the outer grate g and on each side of the'lever h. 4
a are perforations through the top of the coalchamber a.
The tubes 0 c c are made in three pieces. That part next to the fire is made of two walls, with a space, if, 7
between them. These walls are made of cast-iron, and the rest of the tube is made'of sheet-iron. I The inner wall, r,'fig. 7, is made of cast-iron, and
withfa shoulder on each edge. The sheet-iron side is made tolap over these shoulders, and the outer wall.
is then placed over'these two, thus joined, and the whole is fastened by means of the screw and nut s 5.
At the base of the inner wall, fig. 3, are one or more holes, 1),.1eading into the space between these two walls. In the outerwall, and above the last-mentioned holes 1;, is a series of ho1es,n a, whichlead from this space between the walls into the space occupied, by the ascending fire and heat.
0, fig. 4, is a support for the lever h.
The operation of my invention'is as follows:
Goal is fed into the coal-chamber a through a sidedoor,'.which falls down upon the grate.
The grate is made of two pieces, both ofwhich are circular, one of which works within the other. The inner part, f, is made with a declining surface from the central point upon which it revolves. The outer part, 9, is rtiadewith a declining surface from its outer to its inner side. The edges of the two parts of the grate coming g ear together are provided with teeth or notches.
On moving the handle h-from right to left, or vice cersa, the two parts'of the grate will be made to revolve in opposite directions. As the lever h revolves upon the fixed point t, and the points "of contact with the two parts of the grate, through the pins q and I, are oueither side of the fulcrum When moving this'grate in the manner described, the ashes and cinders are thrown down onto the lowest part ofthe-grate, where they are-submitted to the action of the two'toothed edges of the grate, and a thorough, sifting takes place.
To dump the grate, the leverfm is slipped off the support 0, fig. 4, when the inner part f of the grate is turned partially over, as shown by the dotted lines in fig. -6, the bar It, which supports the inner part f of the grate turns uponits supports, and thus allows the inner'partto be dumped the outer part g remaining in a horizontal position.
Air passes into the space between the twowvalls of the pipec c-through the holes 12, and is distributed into the flame and heat through the holesn a, as indicated bythearrows in fig. 3.
The flame and heat from the fuel pass up and around the tubes 0 c 0, thus heating them, andthus keeping a current of hot air constantly passing up throughthe distributingpipes.
' The deflector b, surrounding the coal-chamber a and extending to the air-tubes c c c, forces the flame and heat out to anda-round the air-tubes c 0, thus utilizing much of the heat that otherwise would pass directly up the chimney.
The peiforations a in the top of the coal-chamber allow all gas generated within the coal-chamber, and that does not pass down and out at the side, to escape directly into the smoke-flue, and thus does not come into the room whenthe door is opened for feeding the furnace. The space t between" the two' walls of the tube 0 c is closed at the upper and lower ends. I do not confine myself to the above-described form of a furnace in the use of my grate herein described, but-reserve the right to use it in any kind of a stove that it is adapted to.
The deflect-0r I), made as it is to surround the coalchamber a, and to extend to the air-tube 0, serves also to support and sustain the coal-chamber, thus serving the double purpose of causing the heat and flame fi'om the'fuel to pass around the air-tubes c andof supporting the coal-chamber a.
The perforations in the top of the coal-chamber admitof the gas unconsuined to continuously pass into the smoke-flue, where it is consumed, but the flame does not pass down through the perforations,- and thus 3., Constructing and arranging the two parts f and g of the grate with an inclined surface, substantially as shown, and for the purpose describei 4. Combining the coal-chamber a, deflector In and tubes 0 c, substantially as and for the purpose described.
