FIREPLACE SUPER HEATER Filed July 2, 1962 .2 Sheets-Sheet 2 United States Patent 3,190,282 FIREPLACE SUPER HEATER Walter T. Bauer, Uloiah, Calif. (225 Granada Drive, Mountain View, Calif.) Filed July 2, 1962, Ser. No. 206,574 1 Claim. (Cl. 126131) This invention relates to improvements in heating devices, and more particularly, to improvements of heating devices for fireplaces.

It is an object of the present invention to provide a fireplace heating device that will substantially reduce the tendency of fireplaces without this device to draw air from small openings, such as doors, Windows, and other places, which creates cold drafts, and keeps a constant flow of cold air traversing through the house, towards the fireplace, which makes it difficult to heat any room, excepting the room which has the fireplace in it.

Another object of the present invention is to provide a fireplace heating device that permits air to be drawn freely through the unit, from outside of the house through openings in the fireplace therefor substantially reducing and minimizing cold drafts from doors, windows, and other places, which will, in turn, cause a constant circulation of warm air through the house, thus, making it possible to heat all rooms to the same temperature.

A further object of the present invention is to provide a fireplace heating device that may be installed with a minimum amount of effort.

Other objects of the invention are to provide a fireplace heating device, bearing the above objects in mind, which is of simple construction, has a minimum number of parts, is inexpensive to manufacture and efiicient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description, taken in conjunction with the accompanying drawing, in which:

FIGURE 1 is a top perspective view, comprising the present invention;

FIGURE 2 is a fragmentary perspective view, showing the rear and bottom sides of FIGURE 1; and

FIGURE 3 shows the invention in operation seated in a fireplace.

Referring now more in detail to the drawing, a fireplace heating device 10, made in accordance with the present invention, is shown to include a rectangularly configurated frame 12, having vertical side walls 14, and a rear end wall 16. A palr of spaced apart rectangular baflle plate 18 are secured to the interior of hollow hearth .12, and are angularly sloped toward the center of hollow hearth 12. A rectangular and horizontal baflle plate 20 is fixedly secured to hollow hearth 12, and an elongated, rectangular opening 22 receives incoming air through the lower rear end, and is centrally located between a pair of spaced apart and elongated rectangular openings 24, providing outlet air openings through hollow hearth 12. A tapered conduit 26, having side walls 28, is fixedly secured to the forward end of hollow hearth 12, and extends forwardly therefrom. A hollow fireback 30, of rectangular configuration, is secured at right angles to therear end of hollow hearth 12, and has upwardlyextending side walls 32, and an upper end wall 34, and a pair of elongated, rectangular bafile plates 36 that are equally spaced apart and fixedly secured to wall 16 with in the interior of hollow hearth 12.

In operation, hollow fireback 30 is heated by the radiation of heat from the fire in the fireplace, and air, being drawn through the opening 22, is, thus, heated by the conduction of heat from hollow fireback 30 and is di- 3,196,282 Patented June 22, 1965 rected by the baffle plates 36 through the openings 24 of hollow hearth 12, thus, air is drawn to the fire in the fireplace, and is also distributed throughout all the rooms of the house.

It will thus be recognized that the installation of a small blower on the intake will provide quick warm-ups, for the aforementioned system.

It will be noted that this unit requires an opening at the back or bottom of the fireplace to draw air from outside of the house.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention, as defined by the appended claim.

What I claim as new and desire to protect by Letters Patent of the United States is:

A fireplace heating device comprising, in combination, a hollow hearth, a tapered conduit and a hollow fireback, said hollow hearth comprising a horizontal member having said tapered conduit extending horizontally adjacent one end of said hollow hearth, said hollow fireback comprising an upstanding member adjacent the opposite end of said hollow hearth, said hollow hearth having parallel, spaced apart rectangular top and bottom walls, parallel, spaced apart side walls, end rear wall enclosing a central hollow area, said tapered conduit having a central hollow area communicating with said central hollow area at said hollow hearth, said tapered conduit having a top wall and a bottom wall which form an extension of said top and bottom walls of said hollow hearth, diagonal side walls, and an opening in the tapered conduit at the end opposite the side adjacent said hollow hearth, said diagonal walls converging toward said opening, said hollow fireback comprising a vertical front and rear wall, side walls and top end wall enclosing a central hollow area, the bottom wall of said hollow hearth having a single opening communicating with a vertical central portion of said central hollow area of said hollow fireback, a pair of upstanding bafiie plates within said hollow fireback dividing said central hollow area of said hollow fireback, separating said vertical central portion from the vertical side portions within said central hollow area of said hollow fireback, said bafile plates being spaced from the said top end wall to provide communication of said vertical central portion and said vertical side portions of said hollow central area, an opening at the lower ends of each of said vertical side portions communicating with the central hollow area of said hollow hearth, a pair of baflle plates within said central hollow area of said hollow hearth extending diagonally and convergingly toward said tapered conduit, said baffie plates within said hollow hearth having an opening therebetween and an upstanding plate on the upper side of said top wall of said hollow hearth, and all of the above elements being sealingly attached together.
