3 Claims.

This invention appertains to new and useful improvements in heating apparatus and more particularly to a heater for use in fireplaces, the principal object being toobtain from the products of combustion a greater conductivity of heat to the room space intended to be heated.

Another important object of, the invention is to provide a heater of the character stated which can be readily installed in a fireplace to the extent that the chimney of the'fireplace can be used for the take off of the used products of combustion.

These and other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a front elevational view of the heater.

Figure 2 is a side elevation.

Figure 3 is a vertical sectional view through the heater.

Figure 4 is a fragmentary top plan view.

Referring to the drawings wherein like numerals designate like parts, it can be seen that the shell of the heater consists of the forwardly slanting back wall 5 and the side walls 6, the side walls 6 being provided at their forward edges with outwardly flaring flanges I. A hearth pan 8v is interposed between the forward lower portions of the side walls 6-6.

A substantially broad duct or conduit 9 extends forwardly on the upper portion of the shell and then extends upwardly as at I U, at a point well without the confines of the front side of the fireplace II. The duct has the horizontally disposed and backwardly extending portion l2 which extends into the fireplace and has the rear opening [3 from which the used products of combustion can pass into the chimney.

A Vertical stack or duct l4 extends from the top of the shell and merges with the rear end portion of the portion l2 of the duct or conduit, and at this merging point a bracing flange I5 extends-rearwardly and sidewisely to engage the back and side walls of the'fireplace, .flange l5 being so constructed that it may be fitted in any standard fireplace. 1

A damper plate I1 is sli'dably disposed along the bottom of the conduit portion [2 and by operating the control rod l8 whichis pivotally connected thereto to permit swinging of the door l9 the same can be adjustably slipped over the upper end of the short sack I4 to regulate the draft through this point, governing the amount of the hot products of combustion which is to pass through the ducts 9, l0 and I2.

The control rod l8 extends through the movable plate l9 which normally covers an opening through which a suitable implement can be inserted to clean out the duct.

A chimney seal or flange 20 is provided which extends across and against the upper face walls of the fireplace and upwardly from forward portion of flange l5, fitting around conduit [2.

A cup-shaped unit 2| is disposed depending in the portion [2 of the duct or conduit and has the perforated cover 22. The bottom of the cup 2| is also perforated as at 23.

As can be seen in Figure 1, the cover plate I9 is preferably hinged as at 24 to the portion ll) of the conduit.

Thus it can be seen that the amount of the product of combustion which passes through the conduits 9, l0 and l 2 can be controlled to the desired extent by actuating the damper I1.

As can be seen in Figures 1 and 3, secured to A the lower edge of the slanting wall 9 is the door 26 suspended by hinges 21. This door 26 is complementary to the somewhat narrower lower door 28 which is hinged. as at 29 to the fireplace pan 8.

This lower wall or door 28 can be dropped to the position shown in full lines in Figure 3 or elevated to the position shown in Figure 1 in an upright position to coact with the door 26 to form a front wall structure, which is especially desirable when slow burning of the fire at night is desired. To properly regulate the draft for a slow burning fire when the doors 26 and 28 are used, a slide damper 30 having a hand knob 3| is employed and suitably constructed in the hinged door 28. A swingable armoperative by the knob 32 is denoted by numeral 33 and is carried by Having described the invention whatis claimed as new is 1. A heater for fireplaces comprising a combustion chamber-forming shell, a vertical stack extending from the shell, a forwardly extending conduit, said conduit being disposed outwardly from the shell and having an upwardly and back- I wardly disposed portion, the backwardly disposed portion being open at its rear end, and a damper for controlling draught through the upper portion of the said stack, said damper consisting of a slide plate, a rod for actuating the slide plate, said rod being slidably disposed through the upwardly disposed portion of the conduit, said upwardly disposed portion of the conduit being formed with a soot clean-out opening, a hinged plate for normally closing the opening, said rod being slidably disposed through the said plate.

2. A heater for fireplaces comprising a combustion chamber-forming shell, a Vertical stack extending from the shell, a forwardly extending conduit, said conduit being disposed outwardly from the shell and having an upwardly and -backwardly disposed portion, the baclgwardly disposed portion being open at its rear end, and a damper for controlling draught through the 'upper portion of the said stack, said damper consisting of a slide plate, a rod for actuating the slide plate, said rod being slidably disposed through the upwardly disposed portion of the conduit, said upwardly disposed portion of the.

conduit being formed with a soot clean-out opening, a hinged plate for normally closing the opening, said rod. being slidably disposed through the said plate, said rod being pivotally connected I to the damper plate and having a closure plate i engageable stop at its outer end.

3. A heater forfireplaces comprising a combustion chamber-forming shell, a vertical stack extending from the shell, a forwardly extending conduit, said conduit being disposed outwardly from the shell and having an upwardly and back-p wardly disposed portion, the backwardly disposed portion-being open at its rear end, and a damper MAURICE J.
