JOHN SIM, OF MONTROSE, SCOTLAND.

FIREPLACE-HEATER.

SPECIFICATION forming part of Letters Patent No. 770,396, dated September 20, 1904.

Application filed July 28, 1902. Serial No. 117,369. (No model.)

To all ZUhO'Wb it may concern.-

Be it known that I, JOHN SIM, a subject of the King of Great Britain and Ireland, and a resident of Montrose, in the county of Forfar, Scotland, (whose post-ofiice address is 160 High street.) have invented Improvements in Fireplace-Heaters Used for Warming the Apartments ofDwelling-Houses and other Buildings, of which the following is a specification.

This invention has reference to and comprises new or improved modes of and fittings connected with the design, material, manufacture, and setting or fitting of fireplace heaters to be used for warming the apartments of dwelling-houses and other buildings for the purpose of increasing the amount of heat without a corresponding increase in the quantity of fuel consumed, and in order that my said invention and the manner of performing or carrying the same into effect or practice may be properly understood I have hereunto appended an explanatory sheet of drawings, in which the same reference-numerals are used to indicate corresponding parts in all the figures where shownthat is to say:

Figure 1 is a front view of a fireplaceheater constructed and arranged according to my invention. Fig. 2 is a section of same at E F, Fig. 1. Fig. 3 is a sectional plan at A B, Fig. 1. Fig. 4: is a plan at G D, Fig. l, with the top removed. Fig. 5 is a side elevationrand Fig. 6 is a sectional plan at AB, Fig. 1, showing the back wall and bottom.

In carrying out my invention I make the fireplace-heater mainly of fire-clay or other suitable minerals or of fire-clay in connection with metal fittings and bindings for the front and bottom, enamel outside or tiled, the back wall of the combustion-chamber having hollow spaces within the inner and outer surfaces with openings for admission of cold air and the exit of the air which has been warmed by its passing through the hollow spaces, and in setting these fireplace-heaters in a fireplace which is closed all round and above the fireplace-heater, so that the warmed .air from the hollow spaces and from the exterior of the fireplace-heater is passed into the apartment,

the exit for the products being from the interior of the fireplace-heater, either from the top, back, or from either or both sides of the fireplace-heater, the fireplace-heater standing quite clear of the fireplace all round and not being built into the fireplace or recess for holding it, the only connection being the junction of the exit or exits for the products from the grate with the vent or chimney.

In the drawings, 1 is the top of the fireplace-heater, which may have inside and outsideribs to abstract and radiate the heat, and 2 the exit for the products, which in this particular case passes into the chimney-flue 3 at the back. It is obvious that without matcrially departing from my invention the exit for the products might pass into the chimneyflue from the top or from either or both sides, as has been set forth in the preamble.

4 is the back of the fireplace-heater, and 5 the sides, and these parts are preferably in one piece, as shown, and set clear of the fireplace.

6 is a lifting-lid which is used to cover the air-heating space.

7 and 8 are ribs which do not rise quite to the top, their purpose being to abstract the heat, strengthen the back, to guide the air which is being heated, and to more effectually heat such air. I

9 represents the cold-airv inlets, and 10 the heated-air outlets, these inlets and outlets being at each side or at the bottom of the fireplace-heater.

11 is the fireback, which may have ribs at its back, and 12 the base of the bottom block, which preferably projects in order that it may be used as a support for the bottom of the grate proper, 13.

14: represents fire-clay joints.

15 is the metal front of the fuel-basket, and 16 the ash-pan.-

17 is the stone lintel; 18, the sheet-iron lintel; 19, the sliding door, through which the soot may be removed when the chimney is cleaned, and 20 is the hearth.

The grate operates in the following manner: The coal or other combustible is burned in the fuel-basket in the usual manner, the products of combustion passing into the chimney through the exit 2 in the usual well-known manner. In due course the whole of the fireplace-heater becomes more or less heated, and such heat radiates in all directions into the room and also heats the air which comes in contact With it. In addition the air of the room, or, if desired, air from outside, passes in by the air-inlets 9 or by a flue led to the hollow spaces below the fireplace-heater into the hollow back and sides, up past the ribs 8, and out again into the room by the outlets 10, or another room may be heated by using pipes to conduct such heated air into it.

By using a fireplace-heater designed and operated in the manner described a room may be heated very efficiently and without detriment to health, as the noxious gases or proclucts of combustion cannot mix with the air being heated or-otherwise pass into the room.

Fireplace-heaters manufactured in accordance with my invention may be made in different designs, forms, and colorings, some fireplace-heaters being made or formed of one block or piece of material and others of dif ferent pieces or blocks, in conjunction with metalwork, or fireplace-heaters might be formed of one block in combination with metal-work, each fireplace-heater being fitted or set clear of the fireplace and the exit for the products connected to the vent or chimney, so that no air except that passing through the fireplace-heater flue or fines is admitted to the vent.

hat I claimas my invention, and desire to secure by Letters Patent, is

1. A removable fireplace-heater having the back wall of the combustion-chamber com posed of a front and rear member separated by a plurality of spaced ribs, and side members to said back wall, said front, rear and side members being integral, a fire-pot back supporting said back wall, side walls having air-inlets below and air-exits above, and a top surmounting the combustion-chamber and back wall, and provided with an exit for the products.

2. In a removable fireplaceheater, the back Wall of the combustion-chamber composed of a front and rear member separated by a plurality of spaced ribs, side members for the back Wall, the front, rear and side members being integral, a fire-clay block partly surrounding the fire-pot and supporting said back Wall, and a block at the rear of the ash-chamber and supporting the superposed parts.

In witness whereof I have hereunto set my hand in presence of two witnesses.

JOHN SIM.
