FIREPLACE-RADIATOR.

Specification. of Letters Patent.

Application filed January 21, 1914.

Patented Oct. 6, 1914. Serial No. 813,399.

To all whom it may concern Be it known that I, Jason R. GARMAN, a citizen of the United States, residing at Seattle, in the county of King and State of \Vashington, have invented a certain new and useful Improvement in Fireplace-Itadiators, of which the following is a specification.

My invention relates to improvements in heat radiating appliances which are adapted to be associated with fire places in the rooms of houses whereby there may be effected greater economy in the consumption of fuel, and the object of my improvement is to provide a heat radiator which may be readily attached to fireplaces of the common type and which shall be simple and inexpensive to make and which shall operate to utilize a greater proportion of the heat generated in the fireplace.

I accomplish this object by devices illustrated in the accompanying drawings in which- Figure l is a View in front elevation of my device as it appears when associated with a fireplace and Fig. 2, is a view in vertical section on broken line a2, Q2 of Fig. 1.

Like reference numerals indicate like parts throughout the accompanying drawlugs.

In the operation of the ordinary fireplace, air surrounding such fireplace is drawn inwardly to feed combustion. and thence passes directly up the flue carrying with it the greater part of the heat due to such combustion while only a small portion of such heat is imparted to the room by direct radiation from the fire itself.

Referring to the drawings 5 is a fireplace which is provided with a suitable flue 6 and has the top portion of its back-wall 7 6X- tended outwardly on a curve to a line near the plane of the front surface of the frame of such fireplace and at a short distance below the top edge thereof, a passageway 8 which communicates with the flue 6, being provided directly above the top of the outwardly curved portion of such back-wall 7.

A radiating member 9, preferably of thin metal as of sheet iron, which is slightly longer than the width of the fireplace, has one edge 10 secured by pins 1.1, 11 to the outwardly projecting top portion 12 of the fireplace, as shown in Fig. 2, and is adapted to project forwardly from the front of such fireplace, the other and lower edge 13 of the member 9 being positioned below the front edge of the outwardly curved backwall 7 to leave a passageway between the lower edge 13 and the back-wall 7 for products of combustion, such lower edge 13 being formed with a curved engaging portion that is adapted to engage with the hook shaped upper edge 14: of a fireplace screen 15 which is adapted to be disposed in front of the fireplace as shown.

A small drum 16 is disposed within the member 9 and is adapted to be secured to the forwardly curved portion 8 of the backwall 7, as shown in Fig. 2, such drum 16 being of sufficient size to form a passageway- 17 for heated gases, smoke and the like, be-

tween its wall and the wall of the member 9 I whereby all of the heated gases that are produced by combustion in the fireplace may be drawn through such passageway 17 and thence to the flue 6 thus to heat the member 9 and to cause such member 9 to radiate heat into the room wherein it is disposed.

In the preferred form of my invention herein illustrated, I have provided a plurality of vertically disposed inclosed tubular chambers 18 that are secured to the top portion of the member 9 to communicate with the passageway 17 through openings 19, 19 in the top wall of such member 9, the walls of such chambers 18 serving as additional radiating surfaces.

A flap damper 20 is disposed within said member 9 to extend lengthwise thereof to close the passageway 17 and has its bottom edge pivotally secured to a shaft 21 that lies along the top side of the small drum 16 such shaft 21 being extended outwardly through the sides of the member 9 and provided with a handle 22 on one of its ends by which it may be turned to move the damper 20 to open or close the passageway 17, such damper 20 being adapted when it is in a vertical position, as shown in Fig. 2, to bi-sect the openings that lead to the chambers 18 whereby heated gases from the fireplace may be deflected to pass upwardly into such chambers 18 on one side of the damper 20 s and thence to pass downwardly out of such chambers 18 on the other side of the damper 20 and thence to the flue 6, as shown by darts in Fig. 2.

The screen 15 preferably may be constructed of metal and may have plates 23, 23 of mica or other suitable non-inflammable material disposed therein, as shown in F ig. 1,

and such screen may be provided on its lowermost edge with a plurality of notches 2a or with other forms of openings whereby air to feed combustion may be ad mitted to the fireplace.

My heating device may be applied to any ordinary fireplace by extendin the backwall of such fireplace to confr =m substantially to the shape of the back-wall 7 shown in Fig. 2, and attaching my form of structure in an obvious manner.

The operation of my heating appliance very simple. The screen 15 easily may be remored by-raising the hooked portion 14; of such screen out of engagement with the hookedportion 13 of the member 9 and a fire may then be kindled in thefireplace ,whereupon"the screen 15 may be replaced and the damper 20 be opened, as shown by bro-ken'lines in Fig. 2, to cause air to be drawn inwardly through the notches 2 E l to cause combustion of the fuel in the fireplace, theproducts of such combustion pas ing upwardly through the passageway 17 and outwardly through the passageway 8 into'the flue 6, the heated gases by their contact withthe radiating member 9 serving to heat said member 9 to cause it to radiate heat into the room. After the fuel int'he fireplace has become thoroughly well lighted the damper 20 may be raised into the position shown in Fig. 2, to reduce the draft and to cause the heated gases to be de fiected u nvardly from the passageway 17 into the pipes 18, 18 and thence downwardly again into the passageway 17 from which theypass to the fine 6, whereby such pipes 18, 18will be heatedto act as radiators to warm the room.

The radiating member 9 may be of any ornamental design whereby it may add to thebeauty of the room in which it is used.

Obviously numerous changes in the size and form of the various parts embodied in my device may beresorted to without departing from the spirit of my invention or sacrificing any of its advantages.

What I claim is 1. In a fireplace radiator of the class described, the combination with a fireplace disposed witnin the wall of a room of a buildmg and associated with a smoke-fine extendingto the exterior of such building, of a heat radiator comprising'a curved conduit formed and disposed to project its convex front wall outwardly and upwardly from the top portion of said fireplace to adapt it to conduct products of combustion from said fireplace into the smoke-fine associated with said fire place a screen disposed in front of said fireplace to extend downwardly from the lower front edge of said conduit to the bottom portion of said fireplace and hinged to said edge.

2. The combination with a fireplace and its smoke-flue, of a radiator comprising a conduit projecting outward from the top portion of the fireplace, and adapted to conduct products of combustion into said flue, and a screen in front of the fireplace, extending down from the lower front edge of said conduit to the bottom of the fireplace, the upper edge of said screen and the lower front edge of said conduit being curved to interlock and thereby secure the screen dea ch ably.

In a fireplace radiator of the class described, the combination with a fireplace disposed'within the wall of a room of a building, of a smoke-flue disposed to extend upvardly from a point adjacent to the upper portion of said fireplace, a heat radiator disposed to project outwardly from the said wall of a room infront of the lower portion of said smoke-fine and the upper portion of said fireplace, said heat radiator being provided with a passageway communicating ith the upper portion of said fireplace and with the said smoke-flue through which passageway products of combustion may pass from said fireplace into said smoke-flue to heat said radiator, an upwardly extended and inclosed chamber disposed upon the top of said heat radiator and opening into the passageway thereof, and a damper disposed to be turned to a position at right angles with the direction of said passageway with its upper edge bi-secting the opening into said chamber whereby products of combustion are diverted to pass over the top edge of said damper through the bottom portion ofsaid chamber thence toreturn into the passageway to reach said smoke-flue.

a. In a fireplace of the class described, a smoke flue associated therewith, a radiator member arranged to project outwardly from the fireplace and forming communication between the smoke fiue and fireplace, the lower front wall of said radiator member being curved, and a screen having a hooked upper edge supported on the curved lower edge of the radiator.
