HOT-AIR HEATING SYSTEM.

Specification of Letters Patent.

Patented June 10, 1919.

Application filed February 13, 1917. Serial No. 148,357.

To all whom it may concern Be it known that I, WILLIAM G. FELToN, a citizen of the United States, residin at Wakernan, in the county of Huron and tate of Ohio, have invented certain new and useful Improvements in Hot-Air Heating Systems, of which the following is a specification.

My invention relates to improvements in hot air heating systems, and it consists in the construction, combination, and arrangement of parts, herein described and claimed.

One object of this invention is the production of a hot air heating system which includes primary and secondary jackets spaced apart and fitting over the furnace, together with means for causing the air to be passed within the jackets and over the furnace for heating the air.

Another object of this invention is the )roduction of a hot air heating system which includes primary and secondary jackets positioncd over a furnace, together with fresh air supply means carried by the secondary acket in alinement with the top of the primary jacket, while deflector plates are fixedly secured between the two jackets, and openings are formed in the primary jacket out of vertical alinement with the ends of the deflector plates, whereby air is passed into the device and caused to pass over the greatest surfaces of the primary jacket and the furnace for being heated.

Other objects and advantages of the invention will appear from the following specification, reference being had to the accompanying drawing in which:

Figure 1 is a vertical section of a furnace illustrating the embodiment of my invention, and

Fig. 2 is a plan view of one of the floor registers.

By reference to Fig. 1 of the drawings it will be observed that I employ a furnace 1 which may be of any ordinary construction and is provided with a smoke flue 2. The products of combustion are conveyed to the outer atmosphere through the flue 2. Access may be had to the furnace 1 through a suitably arranged door, (not shown), the various jackets, hereinafter to be described, being similarly provided with openings so that the door in the furnace 1 may be reached.

Disposed about the furnace 1 is a primary jacket 3 which is spaced from the furnace 1 at approximately equal distances. The upper portion of the primary jacket 3 converges as at 4 so as to more readily receive the hot air distributing ipes 5 which are joined therewith in any suitable manner. Openings 6 are formed in the lower portions of the primary j ackct 3 wherein cold air is adapted to pass into contact with the hot air furnace 1 Where it is heated.

Arranged about the primary jacket 3 is a secondary jacket 7 which may rest on a floor as shown in Fig. 1 so that exterior communication through the secondary jacket 7 is closed. The secondary jacket 7 is also spaced at approximately even distances around the primary jacket 3 and receives at places coinciding with the hot air distributing pipes 5, cold air return pipes 8. The cold air return pipes 8 are thus circumposed on the hot air distributing pipes 5 and form7 5 hot air insulating jackets therefor.

Fresh air is supplied through the secondary jacket 7 by means of a fine 9 which leads to an opening 10 in an adjacent wall. A damper 11 in the pipe 9 is used to either partly or wholly close the fine member when it becomes desirable to do so. The line 9 discharges through the secondary jacket 7 at the top thereof so that the air can pass through the acket 7 and will strike the top of the primary jacket 3 and be diverted toward the sides of the jacket 7 where it flows downwardly in the channel or chamber formed by the walls of the primary and secondary ackets 3 and 7 respectively.

The hot air distributing pipes 53 and the circlnnposed cold air return pipes 8 lead to floor register plates The hot air from the pipes 5 is discharged through the register plates 12 centrally thereof from whence the hot air rises and fills the room. The cold air in the room being heavier than the. latter naturally moves toward the floor of the room and is caused to pass through the outer portions of the register plates 12 and to enter the cold air return pipes 8. It will be observed that the adj acent portion of the cold air return pipes 8 is flared outwardly as indicated at 13. The purpose of this construction is to take advantage of the entire remaining portion of the register plates 12 unoccupied by the centrally disposed hot air distributing pipes 5.

Deflector plates 14 are arranged between the inner and outer jackets and 7 adjacent to the outlet of the cold air return pipes S into the jacket 7. These deflector plates 14 are inclined downwardly so that the incoming cold air from the pipes 8 may more readily be directed into the passage or channel between the inner and outer ackets.

The construction of the device having been explained the method of heating is as follows:-The cold air entering the flue 9 and striking the top of the primary jacket 3 will be diverted toward the edges thereof. The current of cold air descending by way of the pipes 8 will meet the current of air discharged from the flue 9 and merge into asingle current which will strike the de' flector plates 14 and pass downwardly into the chamber or channel between the primary and secondary jackets 3 and 7. In passin downwardly the cold air in the pipes 8 wi be preheated. This is so because the greater heat from the furnace 1 naturally rises toward the top and forms an area where the greater heat is present.

The preheated air in the channel between the inner and outer jackets 3 and 7 then passes to the openings 6 at the bottom of the primary jacket 3 whereupon it comes into immediate contact with the furnace 1. In flowing upwardly, the current of air is heated to a still greater degree until it reaches the place of ingress into the hot air pipes 5.

The hot air in flowing out of the register plates 12 toward the upper portion of the room above the register plates and the cold air adjacent to the floor of the room flowing into the outer portion of the register plates 12, causes a circulation of air in the room which is always warm and fresh.

Having thus described my invention what I claim is:

In a hot air heating system, the combination of a fuinace, a primary jacket fitting about said furnace and being spaced there from, said primary jacket having openings formed therethrough adjacent its lower portion, a smoke flue leading from said furnace, a secondary jacket positioned about said primary jacket, deflector plates carried by said primary and secondary jackets, the ends of said deflector plates being spaced apart out of vertical alinement with the openings formed through said primary jacket, a fresh air flue connected to the top of said secondary jacket, in vertical alinement with the top of said primary jacket, thus causing the cold air to be first injected on the top of the primary jacket and then deflected by said plates around the primary jacket and pass through the openings in the primary jacket and be heated by the furnace, hot air pipes leading from the primary jacket and cold air pipes communicating with the secondary jacket.

In testimony whereof I allix my signature in presence of two witnesses.
