AIR-HEATING RADIATOR. I

SPECIFICATIU' forming part of Letters Patent No. 727,668, dated May 12, 1903.

ApplicationfiledNovember20,1902. smart. 132,149. (Nbwdit) Iowa, have invented certain new and useful Improvements in Air-Heating Radiators, of which the following is a specification.

This invention relates to improvements in heating attachments for ordinary heatingstoves, kitchen-ranges, and the like, the ob-.

ject being to utilize the greatest amount of heat possible from the fuel consumed and to take up the cold air from the floor, heating it, discharging it above, thereby keeping up a continuous circulation in the room, heating'and purifying the air.

The invention consists of a vertical drumlike radiator at a point adjacent to the stove and havi'ngan opening at the lower end communicating with the colder air at or near the floor. The air is heated by going up through the radiator and discharged from the hot-air pipe above. The smoke-pipe of the stove enters the radiator near the top of the stove, discharging the heat and smoke from the stove into the space between the inner and outer pipes, the heat radiating through the outer pipe into the room and through the inner pipe, heating the air drawn up from the floor through the open base of the radiator and discharged from the hot-air pipe into the room at the top of the radiator.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure l is a sectional view through the ra- Fig. 2 is an enlarged sectional view showing more particularly the connection between the base and radiator. Fig. '3 is across-section on the line X X of Fig. 1. Fig. 4 is a perspective View of the collar and lid to the base form ing a base to the radiator.

Corresponding andlike parts are referred to in the following description and indicated in all the views ofihe drawings by the same reference characters.

Describing 'the' device in detail, 1 designates an ordinary' stove to which the device may be applied. It will of course be understood that the character of the stove is not essential, so that it has ordinary smoke and heat outlet means. A radiator 2, disposed near the stove, comprises a vertical double casing, a pipe within a pipe of cylindrical form. This radiator rests upon a base 3, full size of radiator, cylindrical in form to correspondwith the radiator,the general contour-of the two elementsbeing the same.

Openings 4., circular or otherwise, are provided at the lower portion of the base 3, said openings admitting the cold air at the floor. To hold the radiator 2 in place upon the base 3, a collar5 of peculiar construction is employed, the same consisting of a fiat ring port-ion a, having a central opening b and upwardly-extending flanges 0 upon the annular edge portions thereof. A downwardly-extending flange d is also formed upon themovable. Upon the inner flange c is attached and held a hot-air pipe 5, which is inclosed by the outer. pipe of theradiator and extends from the open base up through and to the top of the radiator, a cap-plate 6 holding the hot-air pipe centered and closing the space between the inner and outer pipes of the radiator at the top, and this action of the air is continuous, heating and purifying the air of the room orrooms. 'Toheat the the pipe, and in order to better facilitate the heating of the pipe 5 throughout its length deflecting-partitions comprising a semicircular horizontal plate 9 and vertical plates 10, extending down therefrom to a predetermined distance toward the lower end of pipe 5. The plate 9 is located somewhat above the entrance-opening of the smoke-pipe, so that the smoke and heat currents in passing oif are deflected downward under the partitions 10 and pass out through the outlet-pipe 11 at the upper portion of the radiator. It will thus be seen that the pipe 5 is heated throughout its length, and the obvious advantages resulting are important, increasing in proportion to the heating capacity of the radiator. The length of the vertical partitions 10 may be varied according to the spe cial size and construction of the other parts of the attachment, and I reserve the right to make any changes therein consistent with the broad spirit of the invention.

When the fire is being started in the stove, it is always desirable to have as much direct draft as possible, and to admit of this a damper 12 is located on the partition 9, and by regulating same the products of combustion may be used in heating the room or in assisting a perfect combustion by admitting a direct draft to the flame. The said damper 12 is preferably of the oblong type and adapted to open from one side. The valve-stem is journaled at its inner end in a recessed lug upon the pipe 5, no opening being placed in the pipe 5 through which the smoke might pass into the room to the detriment of the atmosphere therein, as will be readily under- Any suitable means for securing the stood.

radiator to the floor may be used, angle-straps 13 being shown in the drawings.

Having thus described the invention, What is claimed as new is In a'heating-radiator substantially as described, an outer cylindrical casing, an airpipe disposed within the aforesaid casing and in closed thereby, a cap-plate closing the space between the casing and pipe at the upper ends thereof and an outlet-pipe located at the upper portion of the outer casing, a base comprising a cylindrical shell having air-inlet openings in its lower portion and adapted to sustain the casing and air'pipe, a collar comprising a flat ring having a central opening and an upwardly-extending flange at its edges to receive the lower ends of the pipe and casing, and a downwardly-extending flange to receive the upper portion of the base, detachable fastenings passing through the flanges and parts of the base and casings adjacent thereto, a smoke-pipe leading into the space between the outer casing and the air-inlet pipe, a horizontal deflecting-plate located above the smoke-inlet pipe and vertical defleeting-plates leading downward therefrom, and a damper disposed upon the horizontal deflecting-plate to allow for direct passage of the products of combustion to the outlet-pipe, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
