HEATER FOR FIRE-PLACES, 86C.

SPECIFICATION forming part of Letters Patent No. 349,324, dated September 21, 1886.

Application filed February 5, 1886. Serial No. 190.954. (No model.)

Sylvania, have invented certain new and useful Improvements ina Combined Fire- Place and Heater; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable 'others 10 skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specitication.

My invention relates to an improved combined re-place and heater, the object being to construct a heater in connection with an ordinary tire-place, and utilize the waste heat from the back and sides of the same; and with this end 1n View my invention consists `in certain details of construct-ieri and combination of parts, as will be more fully explained hereinafter, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of a fireplace having aheater attached thereto comprising my invention.

Fig. 2 is a plan View of the same. Fig. 3 is a sectional elevation of my improvement on Fig. 4 is a sectional view taken through the heater on the line y y, with the coil of pipe g broken away. A

To put my invention into practice, I provide an outside shell or casing, c, of suitable size and form of construction, at the 'rear and sides of which I construct several smoke-pas- 3 5 sages b, communicating With the chimney, and

having two entrances, c, below the grate. At the front of these smoke-passages b, I construct a box, eZ, having a number of horizontal airlues, e, forming a continuous passage from 4o the base to the top. At the base of this continous air-passage e, I introduce an entrancepipe, f, which conducts air from any desired point. At the top and opposite end of the box d, I place or conduct an Vexit-pipe, g,

v4 5 which may be coiled, as shown on the drawings at Fig. 2, thus lengthening the passage of the air over the heated surface. To the front of the box, cZ, I place a heavy tile, h, which forms the back Wall of the tire-place, and on' i, of suitable shape, after the manner usual in fire-places. At the base of the back wall h is placed a perforated or bored plate, j', through which the heated products may pass and circulate about the box or heater (Z. perforations Z at the base of the tile fi are used for the same purpose. An ordinary {iregrate is used in frontot the tile lz, and the entire arrangement is built in the chimney, the front of the casing a being iiush with the outside wall.

The g The operation is as follows: Vhen a iire is made in the grate, which, in practice,will be arranged in iront of the tile h, the products of combustion pass into the smoke-fines b about the box (Z, and after circulating through these iiues pass into the chimney at the upper end of the casing a. rIhe heated air, mixed more or less with combustible products, enters the passages c below the grate and also the perforations Z at the base of the inclined tile rZ, and passes into said iiues b. VI thus highly heat thebox cZ. The air, from any convenient place, is conducted into one end of the continuous air-passage e by means of pipe f, and, following the tortuous course indicated by the arrows on Fig. 4, is discharged in ahighlyheated state into the pipe g,which, being bent back and forward, lengthens the passage on top of the casing aand gives the air in its course a longer time to become heated. This pipe g may be conducted to a room above through the chimney-flue, or to any other desired point. It will be observed that, by means of the passages c and j below the grate and the passages Z above the grate, I conduct portions of the products of combustion mixed with air into the passages b, so that when the Walls surrounding them become intensely heated the combustion of the products will be rendered complete.

I-Iaving thus described myinvention, what I claim, and desire to secure by Letters Patent,

1. In a hre-place heater, the combination, With the casing a, of the air-flue box (Z, arranged and constructed as described and provided with inlet and exit pipes, the smokepassages b, arranged about this box, the pas sages c Z j, communicating with the passages b Ioo 5o the top of this back wall I place another tile,

and thc tiles 7L i iu front of the box and formcj,a1idtl1epassagcsl, all arranged and adapted ing thc back of the fire-place. to operate :ls descxibml and shown.

2. In in fire-place heater, thc air-heating box'. d, constructed as described and com- JOIIN TRUNZICH.
