To all'whom t't nwty. concern.- v h V c it known that I, J onn Gwrns, of Tiflin, in the county .of Seneca, andState of Ohio, have invented a new and improved Mode of ConstructingHeaters for W arming Airffor Buildings; and Ldo hereby declaim that the following is a full and exact description thereof, reference being had to the accompanying draws ings, and the letter'sioi reference marked thereon.

The nature of my invention consists in constructing a heater, so arrangedas to receiveplain sheets of iron, for the heat-radiators, which may be readily. displaced or replaced, without any disarrangeinent of the other parts of the heater, thusenabling those who use this invention, to renew the only destructible part, in

cumstances of its location; fol-it the Fdraught of the chimney is very inferior, the number of radiators may .be reduced to the minimum number. if thdraught of chimney. be powerful, then the number of radiators may be increased to advantage.

Fourth, 'the regulator,.tbrining the top of the fire box, if opened, permits the fire to play directly on the lower radiator, it the heat be i-nsuflicicnt when closed.

1 ifth,the shape of the flues insures the spreading out, in thin layers, of both fire and air, thus absorbing and transmitting all the heat the tire is"capable of generating.

Sixth, the radiators do not necessarily have to receive'the direct action of the fire, which experience shows is better avoided."

To enable others skilled in the art to make and use iny invention, 1 will describe its construction and operation. i h

The fire-box A, figs. 2 and 3, is of brick, on the sides of which, at the top edge, are several openings, for the heat to pass out into the chamber V, under the lower 7 radiator.

The regulator, fig. 4, is of cast-iron, or other suitable material, operated by moving the rod 0 c backward and forward, on the same principleas a Venetian The two inner walls, D'D, figs. 1, 2, and 3, are of brick, with the openings E E, for the heat to pass into the dues F F. a

space, G G, fig. 3, left between it and the inner wall,

of from two, to five inches, in which space, by the partition-columns H H,'are formed those portions of the air and fire-fines, necessary to alter the directions of the currents. l

in mortar thereon, and reach to the outside of the front and-rear walls; then two courses of bricks are laid on it, for sixteen inches at each end, on which are placed the castings J and K; then two more courses of brick are laid, as before described, on which are-placed the castings L and M, of the same shape as J andK last mentioned, but in reverse positions, from left to right, for the purpose of forming the return-flue for air.

the upper radiator, and allow space for the water-pan N. The top is then closed over, with brick or iron, or both, leaving suitable outlets for air-pipes on top, to convey'the'heated air'to the registers. Openings are to be formed inthe left-hand outer .wall, f or the admission of cold air to the radiators, through the'space G, the size of which'openings will be in proportion to the heater.

- The radiators P P P P P are plain sheets of iron, with no other preparation than making the edges parallel, and are slid into the grooves Q Q in the castings II,JK,LandM.

When so placed, the plates marked R are screwed into their places by the nuts S S.

The fines F F in the rear, co-operate with those in the front, '1 T, as I will now explain. I

enters the front lines 'l T, and ascends to the open- .ngs Y Yin the castings L and M, and is again turned by the brick wall at U U, and enters between the two upper radiators, and leaves in-the rear of the same-for the chimney, having thus passed over the whole of the radiating-surface.

The outer walls are also of brick, with a suitable r The inner walls Ill-D are'built up three inches higher than the top of the, firebox, and the castings I I laid The outer walls are then builtnp to a suificientheight to form a chamber for the heated air above l through the openings E E, from the chamber V, it-as- It leaves them through thei'ront openings X X, and

Now, the air to be warmed enters at the opening in the outer wall, and then, ascending between the outer and inner wallsD D, is turned by the flange Z on the casting J, into the opening between the castings I and J, and is thus passed between the first and second radiators; then making its exit on the opposite side, it ascends between the walls until stopped by the flange Z. On the casting L it enters between the third and fourth radiators, making its exit on the opposite side, and asce'nding into the chamber over the top, or fifth radiator, is ready to be conducted to the registers.

I am aware that the flues formed by the radiators may be connected in front and rear, thus dispensing with the flues F F and T T, but I prefer the mode described.

I am also aware that heaters have been constructed with horizontal and with return-fines, and I disclaim either of those devices as being part of my invention.

What I claim, and wish to secure by Lett-ersPatout, is-

1. The cast-iron frames I, J, K, L, and M, and the radiators P P,'counected, as described, together with the front and rear plates marked R R, and the peculiar form of the brick-work in which they are built, for leading the fire and air in alternating, horizontal, and ascending thin layers, at right angles with each other.

2. The use of a plain sheet of iron, without bend, seam, or rivet, connected to an iron frame by means of grooves, as described, for radiating-surfiice.

3. The construction of the iron frames. I, J, and K, with grooves, intended to receive the edges, and allow the withdrawaland renewal of the radiators P P P,
