RADIATING-IVIANTEL.

SPECIFICATION forming part of Letters Patent No. 372,450, dated November 1, 1887.

(No model.)

' To aZZ whom it may concern:

Be it known that I, EMILE BERLINER, a resi dent of \Vashington, in the District of Columbia, have invented a new and useful Improvement in Radiating-Mantels, which improvement is-fully set forth in the following specification.

This invention has reference to the construc tion of mantels, and comprises certain im provements upon the invention described and claimed in my application for Letters Patent filed December 24, 1886,and numbered 222,49i. As described in the said application,the 1nan-. tel, which is specially designed for use in connection with open fire-places, is provided with a metal radiating face or front piece extending above and onto the sides of the fire-place. This metal face forms the front wall of a space or spaces which are in direct communi cation with the tire-place. Above the fireplace and back of the radiating-face is a horizontal partition or deflector, arranged to intercept the smoke and gases in their upward course and deflect them into the spaces behind the face or front piece, through which they pass before escaping to the chimney around the ends ofthe deflector. The face or front piece thus becomes heated over its entire surface and radiates heat into the room. I have found in practice that with a mantel constructed in accordance with my invention, while all the vdesirable features attending open fire-places are retained, a large proportion of the heat now wasted is economized and utilized.

The present invention comprises certain details of construction which experiment has shown to constitute desirable improvements upon the invention referred to above.

According to the present invention the radiating-sheet (which is preferably ofsheet metal) is placed behind a wall or slab, which may be of slate or any material ordinarily used in the construction of inantels. The radiating-sheet therefore heats the air between it and the front Thus there is asteady sliding shutter or blower, which can be drawn down to close the fire-place opening when desired. The partition or deflector extends downwardly at the ends, whereby it answers more efficiently the purposes for which it was designed; and other improvements in details of construction have been made, as hereinafter fully set forth.

In the accompanying drawings, which form a part of this specification, Figure I is a front elevation of a mantel constructed in accordance with the invention; Fig. II, a central vertical section of the mantel and chimney; Fig. III, a partial cross-section on line III, Fig. II; Fig. IV, a view in elevation, partly in section, on line IV, Fig. II, and Fig. V a detail of one of the castings.

A represents the metal radiating-face; B,the fire place; O,the mantel-shelf. Behind the ra diatingface A are the spaces 1 2,in direct communication with the fire-place. In front of the radiating sheet A is a slab, A, which forms the front of the mantel. This may be of slate or marble or other material. A space, 15, is thus formed between sheet A and front A, and the air thercin,becoming heated, rises and escapes into the room through openings 16 at the top of the mantel. \Vhen the mantel is used in a dining-room, these hotair openings are useful for warming plates and dishes.

The rear wall of the smoke passages or spaces 1 2 is a sheet-metal piece, 17, which is secured to the sheet A by a number of bolts, 18. These bolts serve to support the partition or deflector 3, and they are also impor tant in preserving the relative positions of the sheets A and 17, preventing warping or buckling.

The partition or deflector 3 is extended downward (see Fig. IV) on both sides of the fire place. The space 1 is thus separated from the side spaces, or passages by vertical partitions. By this construction a greater amount of heat is intercepted in the space 1, while the products of combustion pass around and under the ends of the deflector 3. Thence they pass by way of spaces 2 to the horizontal flue or passage 6, formed between the deflector 3 and top piece,'5, and finally pass through smoke-hole 7 to the chimney.

The radiating-sheet A is braced by a casting, 19, (shown in perspective in Fig. V,) which is placed in front of said sheet. This casting is shaped at the bottom to correspond with the fire-place opening. Each side is turned over, as shown, to form ways or guides for a sliding shutter or blower, 20. This is supported just in front of sheet A by cords or chains 21,passing over pulleys 22, and having at their ends counterbalanceweights 23. This shutter or blower can be drawn down in start ing the fire, and afterward pushed up into the position shown in the drawings, Fig. II.

Another casting, 24, is placed around the fireplace opening and holds the sheet'r'netal back 17 of the smoke flues or

spaces

1, 2, and 6 against the breast D of the chimney. The casting 24 has at the top a backwardly-projecting flange, 25, which holds in place the end of the sheet-metal chimney-plate 10, by

which the usual communication between the fireplace and chimney is cut off.

This plate 10 is inclined forward over the grate 13, as in my former application.

The bottom of the chimney is closed by a horizontal sheet, '26,;

which forms, with the rear and side walls of fl re.

This heated air ascends through an} opening in sheet 26 into hot-air pipe 12,\vhich 2 passes up through the smoke-flue 8, and may 1 communicatewith a register on the floor above.

Theproducts of combustion ascending through flue 8 impart additional heat to the air in pipe 12.

It is obviousthat modifications may be made in details of construction, proportions, and j materials without departing from the spirit of the invention, and that parts of the invention i may be used without the whole.

Having now fully described my said iuvention, what I claim is- 1. The combination of the upright front wall or slab having openings near its top, the upright radiating-sheet behind said wall or slab, these parts inclosing between them an airspace, and smoke flues or passages directly behind said -radiating-sheet,so that the latter is heated by the products of combustion passing from the fire-place to the chimney, the air passing behind said front wall upward between it and said radiating-sheet,and finally fire -'place, and the perforated mantel-shelf 60 forming the top of said air-space,substantially as described.

3. The combination of the upright radiating-sheet extending above and around the tireplace, the smoke flues or passages in the rear of said sheet and communicating directly with the fire-place, so that the products of combustion pass on their way to the chimney in contact with the inside of said sheet, and the frame or casting surrounding the fire-place opening and bracing said sheet, substantially as described. V

4. The combination oftheupright radiatingsheet extending above and around the fireplace, the smoke flues or passages in the rear of said sheet and communicating directly with the fire-place, and the casting surrounding the fire-place opening and supporting said sheet, thesides of the casting being provided with gu-ideways, substantially as described.

5. A fireplace having an upright radiatingsheet extending above and on each side of the grate, smoke passages directly behind said sheet and communicating with the fire-place,

i a deflector behind saidsheet and above the grate for directing the products of combustion into said smoke-passages, a rear plate or wall, and bolts supporting said deflector and servingalso to brace said radiating-sheet, substantially-as described.

In testimony whereof Lhave signed this specification in the presence oftwo subscribing-witnesses.

EMILE BERLINER.
