OPEN-FIREPLACE HEATER.

SPECIFICATION forming part o f Letters Patent N o. 485,301, dated November 1, 1892.

Application filed April 30, 1892.

To @ZZ whom it may concern:

Be it known that I, GEORGE RANDAULPH SCATES, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee,have invented a new and useful Open-Fireplace Heater, of which the following is a specification. l

My invention relates to heaters for open fireplaces, the objects in view being to provide a heater adapted to be set in an open fireplace and to thoroughly and efficiently distribute its heat throughout the several compartments with which it may be connected, which may be adjusted to fit or accommodate itself to various thicknesses of walls, and which will secure a complete combustion, or nearly so, of the fuel and will utilize to a greater extent than usual the products of such combustion for the purpose of heating by radiation.

With these objects in view the invention consists in certain features of construction hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a vertical transverse section of a heater embodying my invention. Fig. 2 is a front elevation of the fireplace. Fig. 3 is a similar view of the hot-air box. Fig. 4 is a vertical longitudinal sectional view of the grate. Fig. 5 is a similar view of the hot-air box.

Like numerals of reference indicate like parts in all the iigures of the drawings.

1 designates the chimney of a house; 2, the Second door; 3, the flue within the chimney; 4, the chimney-pipe; 5,the chimney-opening; G, the floor below or first door, and 7 the registeropenings of the second `fioor leadingfrom the ue. Thelowerfloor 6 has an opening 7 within the chimney-opening, and communicating with said opening is a cold-air-supply pipe S. Vithin the chimney-opening there is located the tire-box 9, and the same terminates at its upper end in a dome, which is connected to the smoke-pipe 4 by an elbow 10, in which a damper 11 is mounted and controlled by arod 12, which extends through an opening formed in the facing-frame 13, that surrounds the front of the chimney-opening 5, and back of which is located the fire-box. Thefacingframe 13 has a register 14, through which radiated heat may pass.

tend inwardly from the opposite side walls of the tire-box and through curved slots 16, with which the opposite ends or curved terminals 17 of a U-shaped frame are provided. The U-shaped frame also has a fronttransverse bar 18. 19 designates the grate, which is pivoted at 2O to the extremities of the terminals 17. .The rear edge of the grate takes under a series of vertically-disposed angular deliecting-ribs 21, whereby it is supported in position or its movement limited.. By engaging a poker or other device with thebar 18 it will be seen that the grate may be inverted, or partially so, and its contents dumped. Below the grate the back wall of the fire-box is provided with a series of air-inlets 22, which insure complete combustion at the rear end of the grate and prevent the accumulation of unburned or half-burned coals.

23 designates a hot-air box, and the same is provided with alower base portion 24, which communicates with the chimney-opening and receives air from the pipe S through anopening 25. The front wall of the base has an opening for the removal of dust in cleaning the box and for the admission of cold air, which opening may be covered by adoor 26. Near the upper end of the box a pair of transverse pipes 27 pass entirely through from rear to front wall thereof and are open at each end, the front end being covered by a perforated register-plate. These pipes 27 are connect-ed to thehollow base 24 by a pair ofvertical pipes 20. Adoor 30 is located at the front side of the box to give access to the pipes and increase the admission of cold air when desired. The backs of both the fire-box and hot-air box have pipe-sections 31 projecting therefrom, and the pipesections of one telescopically connect with the sections of the other, so that, as will be seen, an adjustable connection between the lire and hot-air boxes is made. From the upper end or dome of the hot-air box to the upper end of the elbow 10, above the damper 11 therein, there leads a pipe 32 for passage of smoke.

33 designates a delecting-plate, which extends transversely in the upper end of the tire-box 9. Arod 34 is secured rigidly to the plate, the ends of the rod taking over and moving in guides 35, which are curved, as shown, and concentric with pivots 36 of a IOO pair of swinging rods or arms 37, the upper ends of which are loosely connected to therod 34. This deflecting-plate 33 may be swung rearwardly, so that it practically covers or is interposed between the fire and inner ends of thepipes 31, and thus the heat would be deflected into the room, or by swinging it forwardly a portion of the heat will be permitted to pass rearwardly direct through thepipes 31 into the hot-air box around and among thepipes 29 and 27, and inally out through the pipe 32 to the smokepipe, and when drawn to the front closes the grate, acting as blower. The cold air passes from the pipe 8 through thebase 24, vertically through thepipes 29, thence outwardly into the space or opening 5 of the chimney, where it is joined by more air, which has become heated by contact with thepipes 31 and back portion of the hot-air box. Some of this heated air passes laterally through the register-openings 28 into the room, while the rest of it will pass through the register-openings 14 of the room opposite or up the flue and through the openings 7 of the' second fioor, and during its passage will be in contact with the smoke-pipe 4, and in this manner the products of combustion are utilized to their fullest extent, and a constant supply of pure cold air is being heated and c onducted to the various compartments wit-h which the heater is connected. Y

Having described my invention, what I claim is 1. In a heater of the class described, the combination, with the lire-box, of the hot-air box located in rear thereof, the smoke-pipe leading from the upper end of the fire-box and communicating with the upper end of the hot-air box, cold-air inlets for the hotair box, transverse pipes through the hot-air box, vertical pipes leading from the cold-air inlets to the transverse pipes, pipes between the fire-box and the hot-air box, and a movable deflecting-plate pivotally supported below the pipes between the lire and hot-air boxes, substantially as specified.
