ELIVIER 1V1. WRIGHT, OF PORTLAND, OREGON.

HEATING AND VENTILATING SYSTEM.

Application filed December My system relates to a heating system or furnace, or stove, as is ordinarily used wherein fuel is being burned within the central fire box having disposed therearound a shield to prevent an intensified heating Zone being created in the immediate vicinity of a heating plant, and has for its object the creation of a uniform temperature within the room, or compartment to be heated and the ventilating of the same.

A further object of my invention, conslsts in providing means for the inductlon' of a supply of fresh air from the exterior of the compartment; selective means or shuttlng off the supply from the exterior and circulating the air to be heated withln the room itself. I p 3 A further object of my invention consists in providing means for increasing the draft of the vitiated air through or about the heating stove and exhausting the same from the room, through suitable exhaust pipi 11g.

l/Vith these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and to a preferred form of embodiment ofwhich is hereinafter shown with reference to the drawings, which accompany and form a part of this application.

In the drawings Fig. l is a perspective view of one of my new and improved heating devices, shown 1n position and connected to and from the exterior of the building, wherein the same is installed. r

Fig. 2 is a vertical cross section view through the heater illustrated in Fig. 1.

Fig. 3 is a cross section view, taken on line 33 of Fig. 2, looking in the direction indicated.

Fig. 4 is a cross section view, taken on line 44 of Fig. 3, looking in the direction indicated.

Like reference characters refer to like parts throughout the several views.

1 is the fire box, having a hinged fuel in-' let 2, disposed at the top of the fire box, the same being hinged by hinges 3. A draft control inlet 4, is disposed at the front thereof and having a hinged closure 5, with means for admitting air therethrough. A smoke pipe 6, provided at the top of the heater is adapted to carry away the products of combustion. A jacket 7 is disposed 15, 1925. Serial No. 75,511.

about the fire box and spaced apart therefrom as shown at 8. The bottom 9 of the fire box extends beyond the fire. box and forms also a bottom for the space'S, disposed between the fire box and the shell the same being shown at 10. A conductor pipe 11, connects the heating member with the ex terior of the buildingand conducts freshair y from the exterior of the building into the space surrounding the fire box and discharges the same between the fire box and the jacket ,7. I have provided'a header at the end of the conductor pipe 11, having discharge outlets 11 and 11 disposed at either end of the header and adapted to discharge the fresh air supply into the space between the fire box and shell 7, in order'that the same may bring the fresh air, to be heated, in contact with the fire pot at its lowest extremity; the header and the conductor pipe are connected by risers 13, for carrying the vitiated air into the heated space. A damper 12 is disposed in the conductor 11 to stop the flow of air from the exterior through the conductor 11 and an inlet damper l3, permits the inflow of air from the room to be heated into the space disposed between the fire box and the shell; the object of which is to permit a selective means for determining which air is to be heated and whether the same is to be taken from within the room or from without the room. It is a well known fact that warm air rises and the cold air falls to the lower levels. It is also a well known fact that the heavier stratas of air are disposed within the lower levels. r

I am aware thatattempts' have heretofore been made for creating within the one heating element of a heater for the heating of the air within the, room without creating a highly heating zone and at the same time to create a, ventilating system thereby, by taking the colder stratas of air from the lower level and passing the same from the room to be heated to the exterior of the room; I am also aware that an induced draft hasheretofore been created and I am not claiming the invention broadlly, excepting in the specific manner in which Ibring about this result, which I do eiiieiently and economically. 1

The colder stratas of air are passed about the bottom of the stove around the base jacket 14:, disposed about the base'of the fire box and flow onward into the exhau t pipe 15. This exhaust pipe 15, passes in the immediate proximity of the heating zone, and between the fire box and the shell, and the air passes therethrough becomes heated which increases the draft and permits of a greater volume of air being exhausted therethrough. A damper 16, is disposed in the outlet pipe 17, to permit the manual regulation of the draft, or volumes of air being passed I therethrough.

While the form of apparatus herein shown and described isadmirably adapted to fulfill the objects primarily stated, it is to be understood that it isnot intended to confine the invention to the one form of embodiment herein shown and described, as it is susceptible of embodiment in various forms, all

coming within the scope of the claims which follow: 7

1. In a heating and ventilating system, the combination of a heater, an outer jacket therefor, and spaced apart therefrom, the

bottom ofthe heater being extended to and connected With the lower edge of said jacket;

an ail conductor leading from an exterior point and teri'ninating in outlets into the space between the jacket and the heater, at the bottom thereof, and an exhaust pipe having an inlet formed through the extended bottom or the heater, and passing upwardly between the jacket and the heater to an exterior point. I

In a heating and ventilating system, the combination of a heater, an outer jacket disposed about said heater, and spaced apart therefrom, the bottom 01" the heater being extended outwardly to connect with the lower edge of said jacket, an air conductor leading from an exterior point and terminating at its inner end in outlets into the space between the jacket and the heater, and at the bottom thereof, means to regulate the flow of air through inlets formed in said conductor, and an exhaust pipe having an inlet I formed through the extended bottom of the heater, and passing upwardly between the jacket and the heater to an exterior point.
