AUXILIARY FIREPLACE-HEATER.

Specification of Ihetters Patent.

. Patented Dec. 7, 1920.

Application filed September 3, 1919. Serial No. 321,505.

) To all whom it may concern Be it known that I, ALEXANDER DUNCAN MoLnon, of the town of Arcola, in the Province of Saskatchewan, Canada, have invented certain new and useful lmprove which the followin is the specification.

The invention re ates to improvements in fireplace heaters and the general object of the invention is to provide a device designed to conserve and utilize. the

heat in open fireplaces and ordinary wasted their heating capacity as a thereby increase heating agent.

A further object is to provide a construcobject which can be readily installed when the fireplace is being built, requiring no change in the exterior appearance of the fireplace and in no wise decreasing itsbeneficial value as an open grate fire.

. A further object is to arrange the parts so that they can be readily assembled and set up.

With the above more important objects in view the invention consists essentially in providing a hot" air chamber around the fi're box and pipe leading from the firebox and" providing suitable air vents in connection with the air chamber to permit of the circulation of the air heated by the chamber within the adjacent room or rooms, the parts being arranged and-constructed as hereinafter more particularly described and later pointed out in the appendedclaim, reference being had to the accompanying drawings in which v Figure 1 is a view of a fireplace part in front elevation and part in vertical section.

Fig. 2 is a vertical sectional view through the fireplace, the section being taken 'at 11' Fig. 1. v

Fig. 3 is a horizontal sectional view through the fireplace, the section being taken at 3-3 Fig. 1.

Fig. 4 is a side view of the fire box with the collar applied thereon.

Fig. 5 is a side view of the collar.

Fig. 6 is a side view of part of the'hood.

Fig. 7 is a perspective view of one ofthe spacers for the pipe.

In the drawings like-characters of reference indicate corresponding parts in the several figures. I

' The base 1' of the fireplace is made from and then I provide an interior air wardly extending neck 3, the sides and front of the neck inclining upwardly at an angle of approximately 45 degrees while the back is vertical. Within this fire box the customary grate 4 is located. To the neck I securely rivet a circumscribing flat band 5 drill suitable holes through the band and neck and tap these to receive set screws 6 which secure the collar 7 to the neck. The collar is formed with a bottom part complementaryito the inner face of the neck and with an extending upstanding flange 8 which projects upwardly beyond the neck.

By providing the band and tapping it in the manner disclosed one can readily set up the collar by first inserting it in position within the neck and then inserting the screws from the inside and tightening them up.

The flange of the collar receives-the hood 9, the bottom part of which is substantially rectangular to fit around the flange and the upper part of which flares upwardly and inwardly at the sides and terminates in a contracted circular end 10 which communicates with the lower end of the smoke pipe- 11, this pipe passing upwardly of the building and terminating at the chimney. The

per 12 of ordinary form which can be mani ulated fromv the interior of the room.

he fire box and hood are contained with in a receiving casing 13 spaced at the back and sides from the fire box and hood to chamber 14 utilized.

for heating purposes.

At .the front the easing is flanged out around the front of the fire box and a flat band 15 is here also applied on the flange to which it is riveted and'the band is. drilled and tapped'to receive fastening set. screws 16 similar to screws 6. -The upper part of the casing flares inwardly at the sides and is continuous with a sheet metal pipe. 17 spaced from the pipe 11 to form a continuation of the chamber 14:. In Figs. 1 and 2 of the drawings the pipe 17 is shown as extending upwardly to the first floor 18 of the room where it closes in to the pipe 11 and thereby Of the air chamber.

Suitable spiders or spacers 19 are inserted between the pipes, such in the present instance being made from wire (see F ig. 7) so that they will not interrupt the circulation while serving to space and stay the inner pipe.

The pipe 17 actually ordinary brickwork 20 fireplace.

From the above disclosure it will'be apparent that the fire box as well as the smoke pipe 11 leading from the fire box is surcloses off the upper end of the chimney and rounded within the wall by an air chamber,

the air in this chamber being naturally heated by the heat radiating from not only the back and sides of the fire box but also from the smoke pipe. The hot air chamber so provided is utilized to advantage in heating the room, cold air vents 21 and 21 being provided adjoining the ground floor to admit of cool air entering the bottom of the air chamber while a hot air vent 22 is provided at the top adjacent the ceiling, such permitting the hot air to pass from the air chamber into the room.

Obviously when the fireplace is 'in use the, circulating heated air Will add materially to the value of the fire place as a heating agent and Will not detract in. the

slightest from its value as an open grate. The vent opening 22 can be provided with a suitableregister 23 controlling the circulation. Y

While I have described the various parts forms a lining to the i smoke in detail, still it will be understood I do not wish to be limited to the precise construct on shown as the various parts can be readily modified without in the least depart culation within the adjacent room or rooms.

WVhat I claim as my invention is:

In an open grate fireplace, a fire box pro-- vided at the top and toward the rear with an upwardly extending neck, a band permanently secured to the'outer side of the neck. said band and neck being suitably spaced screw threaded openings, a collar inserted within the neck and extend -ing above the same, screws securing the colto the band, an uplar throughthe casing wardly flaring hood having the lower end. mounted ',on the collar, a smoke pipe communicating with the uppcr end of the hootb an inclosedair chamber surrounding-the fire box and smoke pipe, said air chamber extendingfor a considerable distance up the pipe, a cold air vent opening to the bottom of-the air chamber and a warm air Igent'leading from the top of the air champrovided with Signed at Arcola',-this 4th day of August, 19.

ALEXANDER DUNCAN McLEOD. In the presence of- NELLIE HoE'Y, H. J. DARRAOH.
