SPECIFICATION forming part of Letters Patent No. 374,649, dated December 13, 1887.

Application filed November 9, 1886. Serial 219.4%. (No model.)

To all whom it may concern:

Be it known that I, QUIMBY S. BAOKUS, a citizen of the United States, residing at Winche'ndon, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Heat-Radiating Mantels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is a mantel or fire-place front of such form and construction that it serves as a steam or hot-water radiator. Two forms of the Same are herein described, and the in vention pointed out in the claims.

In the drawings, Figure 1 is a front elevation-of one form of mantel embodying my invention. same on line 00 m, Fig. 1. Fig. 3 is a section on line 3 y, Fig. 1. Fig. 4 is a section on a like line of a modified form of my mantel. Fig. 5 is a transverse section of one side of such form of mantel on line 2 a, Fig. 4.

The same letters in the drawings indicate like parts.

I construct my mantel of four parts, A B O 0, preferably of metal. Of these parts 0 0 constitute the sides or jambs of the mantel and are placed at each side of the fire-place niche. The part B is placed above and upon these two parts and extends across the fire-place from one to the other. The part A is above this part B, and is provided ordinarily with a mantel-shelf. The parts 0 G are made with a chamber or receptacle, 0, in each, and the part B is also hollowed or chambered. The chamber 1) within this latter part of the mantel is connected by pipes b with the chambers c in the jambs. When this mantel is used in connection with a steam-heating system, it is provided with an air-valve and with inlet and outlet 1 and 2. The fire-place can then be provided with a gas-log, which may be lighted to imitate a grate-fire, the log affording thelight and the mantel the grate part of the heat for the room. The mantel can in a similar manner be placed in a hot-water system.

I prefer, in most cases, to employ with my mantel a water heater or steam generator, D, forming part of the gas-log or placed in Fig. 2 is a vertical section of the v close proximity thereto. This water-heater or steam-generator is connected by pipes d with the chamber 1) of the mantel, and is also connected by pipes d with the lower part of the chamber a in the jambs. The water in the water back or log, on being heated, passes up through the pipes d into the chamber b and thence, as it cools, downward through the pipes b to chambers c, then through pipes at into the log or back again, forming a complete circulation, in the course of which its heat is radiated or given off through the surface of the mantel to the air of the room.

It will be noticed that the construction with the water-back or steam-generator is as well designed for use with a coal or other form of fire as with a gas log or burner. is also of a hollow form, and the jambs below the chambers c are also hollow. These spaces are not utilized in the construction just described; but in the modification shown in Fig. 4 I provide the front walls of thesespaces with perforations, as shown at e. The rear of the jambs is provided with a shallow upwardpas sage, E, which is continued upward and communicates with the space or chamber in the part A. The front wall of this passage is the rear wall of the chamber 0 and may be made corrugated, so as to provide additional heatingsurface.

The cool air of the room passesin below the chambers c, then upward through the passage E, and is heated in its upward movement therethrough; It is then discharged into the room throughthe part A and the openings in the front walls thereof. By this means all the heat of the water or steam in the mantel is fully utilized and there is little or no loss of heat.

The parts may be connected in any usual manner, and the ,form and connections of the The part A heating-chambers of the mantel may be differnecting the same above the fire-place communicating with the hollow jambs, and steam or water inlets, substantially as described.

3. The combination, with a hollow or chambered mantel, of a water-back communicating with said mantel, substantially as described. 4. The combination, with a hollow or chambered mantel, of awatenback communicating with said hollow or chambered mantel at two or more points at different elevations, substantially as described. v

5. The combination, with ahollow or chambered mantel, of a water-back, pipes d, connecting the water-back with the mantel above the water-back, and pipes connecting the mantel with the water-back on a level with the latter, substantially as described.

6. A mantel consisting of the hollow parts 0 O, the hollow part B, communicating with the parts 0 C, and the hollow part A, provided with a mantel-shelf, substantially as described.

7. The combination of the hollow parts A B C O, the said parts 0 0 being provided with chambers c and recesses below the same, and having openings through the front walls of said recesses, of the pipe E, connecting said recesses with the interior of A, said part A being provided with openings in the front wall of the same, substantially as described.

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