JOHN B. OLDERSHAW, OF BALTIMORE, MARYLAND.

FIRE-PLACE HEATER.

SPECIFICATION forming part of Letters Patent No. 242,027, dated May 24, 1881.

Application filed March 3, 1881. (N0 model.)

To all whom it may concern Be it known that I, J OHNB. OLDERSHAW, of Baltimore city, State of Maryland, have invented certain new and useful Improvements in Fire-Place Heaters;'and I hereby declare the same to be fully, clearly, and exactly described as follows, reference being had to the accompanying drawings, in which Figure l is a front elevation, and Figs. 2,3, and 4 are sectional views, respectively, on the lines w as, 3 y, and z 2.

My invention relates to fire-place heaters, or that class of stoves designed to heat upper apartments by means of fines leading from the air-drum of the stove, as well as to heat by radiation the apartment in which the stove is situated, and it has for its object to so combine with the stove a system of drums or air chambers and fines as to deliver into the room containing the stove a current of hot air, and to the upper apartments a distinct current of air, and to so arrange the fines and drums as to properly attemper the currents of air and equalize the heat.

The obstacle has heretofore been met in this class of stoves that the stove either insuffiproviding a flue or fines leading from near the base of the stove to the air-drum, and thence to the upper chambers, and a second series of flues, opening into the cellar and leading to the upper portion of the stove, and delivering the heated air over the top of the stove into the room in which the stove is situated. These flues pass up at the side of the stove through the air-drum which supplies the upper chambers with hot air.

The two air chambers or drums or flues, as they may indift'erently be termed, are contiguous to each other and to the fire-chamber, and as a result the currents of air are properly heated and a comfortable temperature is maintained in both the lower and upper apartments. The stove embodying the features about to be described, and which I have denominated the Pride of Baltimore, has justified in practice 'the above statement.

In the drawings, A is the stove-front, having the usual mica windows, a, and B is the coal or feed opening. M is the magazine. 0 is the opening for the ash-drawer, and G is the grate. These parts are all of the usual construction.

Iis a drum, inclosing the rear half of the stove, which drum receives the air through the openings D, near the base, and delivers it through the opening L to the fines leading to the upper apartments.

H H are a pair of fines contiguous to the stove-body and having openings h h at their lower portion leading to the cellar. At their upper ends they terminate flush with the top plate, 0, of the fire-chamber, which plate is perforated, as at it. (See Fig. 3.) A drum or chamber, K, surrounds the rear half of the stove-chamber above the plate 0 and opens through the plate I? under the inclined hood E. In lieu of this the flues H may be made to communicate with the air-ducts leading to the upper chambers, and the drum I may supply hot air to the apartment in which the stove is placed.

F is the flue for the products of combustion, having a nipple, F, for the attachment ofthe stove-pipe.

In operation, the air enters the openings D and is heated within the drum I by contact with the walls of the stove and finds exit at -L to the upper chambers. Another current enters the tines H from the cellar, and, passing up through the same within the drum I, and contiguous to the stove-walls, streams out under the hood E into the lower compartment. The two currents thus, as it were, attemper each other and equalize the heat.

I have considered it unnecessary to show or describe the dampers, which are arranged to close or partially close the flues, as they are of the ordinary construction and naturally suggest themselves.

I am aware that it is not new, broadly, to heat two distinct currents of air, the one being led from the apartment in which the stove is placed and the other from the cellar or else where, andsnch I do not claim.

What I claim is-- 1. In a fire-place heater, a casing or drum the stove and supplying air to the tines leadinclosing an air-space at the rear portion of ing' to the upper apartment or apartments, and one or more air-fines contiguous to the Wall of the stove and located within the said casing, whereby the temperature of the currents of hot air is equalized, as set forth.

2. In a tire-place heater, a casing or drum inclosing the rear portion of the stove, and forming an air-clntmber having an inlet opening at the front ot'the stove and an exit-orifice communicating with the tines which lead to the upper chambers, and a pair ofair-tlues eontiguous to the wall of the stove and within the said casing, which flues receive air from the cellar below and discharge it over the top of the store at the front, as set forth.

3., In a fire-place heater, a semi-cylindrical casin, inclosing an air-chamber at the rear portion of the stove, and a pair of semi-cylindrical fines, H, contiguous to the stove-wall and within the said. casing, and suitable openings whereby distinct currents of air are led from the base of the stove through the casing and over the fines to the upper apartments, and from the cellar below through the fines to and over the top of the stove, as set forth.

4. In combination with the stovebody, the inclosing casing or drum, having an opening, 1), on either side, and the tines H contiguous to the stove-Walls Within the drum, the chamber K, and hood E, as set forth.
