vE|-1T`|LAT|Nev APPARATUS.

SPECIFICATION forming part of Letters Patent No. 538,976, dated May 7, 1895.

Application iled May 24, 1893- Renewed October 20, 1894- Serial No. 526|484= (No model.)

To a/ZZ whom it may concern:

Be it known that we, WILLIAM F. MCGUIRE and FRANK E. MCKENNEY, citizens of the United States, residing at Rockford, in the county of Winnebago and Stateof Illinois, have invented certain new and useful Improvements vin Ventilating Apparatus, of which the following is a specification.

The object of this invention is to ventilato the rooms heated by a hot air furnace, by creating an escape for the cold and foul air which occupies a space near the oor, and conveying such cold and foul air to the fur. nace and thence to the chimney or cold air shaft.

' The further object ot this invention is to produce a check valve for the Ventilating apparatus in order to prevent the backward .the room than the valve preventsthe admission of air from the draft of air into the rooms.

In the accompanying drawings, Figure 1 is a vertical section through the Ventilating apparatus; Fig. 2 is a verticalsection through the check-valve. Fig. 3 is a section of the connection of the pipes 6 and 7 with the room. Fig. It shows the connection of the pipe 3 and l 1t with the chimney.

The furnace 1, in this instance is of a well known construction. Around thisfurnace is located a jacket 2, in the upper portion of which is located a V-shaped partition 3.

A smoke pipe 4, communicates with the furnace and with a chimney. From the top ofthe upper compartment extends a pipe 5, which surrounds the smoke pipe 4, the two communicating with the chimney.

From the upper portion ofthe casing radiate pipes 6, conveying heat to the room, and Ventilating pipes 7, extend parallel with the I heat conveying pipes until near the furnace where they pass inside the -latter pipes and -communicate with the compartment in the top of the casing.

In the pipe 5, before the smoke pipe enters it is located a check-valve preventing the backward draft of air to the rooms and consists of a valve 8, having alhinged' or pivotal connection with the casing '9. 'A rod- 10,v is connected to the -valve and a-weight 11, is made adjustable along the' rod. The sides of the casiug'are provided with openings, which 'are covered with mica'l2. r

Cold air is taken in at the-bottom of the furnace,.wliich after circulating around the .theroom and leading furnace ascends the pipes 6, to the room, and

after circulating around the room until it becomes cold, will'descen'd the pipe 7, and enter the compartment in the top of the casing, and from thence passes to the chimney or coldair shaft by means of the pipe '5.

The pipe 7, is located on a lower level in pipe 6, and as the check chimney into the compartment in the' top of the casing the air mustbe supplied from theroom, and as the air in the compartment becomes heated it will escape to the chimney creating a circulation of air, drawing the cold and foul air from the room, which is replaced by pure heated air ascending the pipe 6. By extending the pipe 7, a portion of its length within the heat conducting pipe 6, it will assist in heating the cold air on its passage to the chimney, and the air will be further heated bythe smoke pipe extending a portion of its length inside of theventilating pipe on the chimney sideof the furnace.

Owing'to the valve being nearly balanced, should the air blow down the chimney the valve would instantly close, preventing the admission of air to the room. It is often the case thatrooms are not properly heated by hot air, owing to the fact that such rooms are kept closed', preventing the escape of the cooled air, land consequently-circulation, but by our arrangement, we get a complete circu- 8 5 lation as by means of our Ventilating pipe the cooled air is carried away allowing the admission of heated air to take its place.

It is evident that a series of Ventilating and air conducting pipes may be connected with the heating drum and outer casing.

We claim as our invention- In a Ventilating apparatus,a heating appa-A ratus having a closed chamber in itsy upper portion, a Ventilating pipe connected ,withchamber, a heat conducting` pipe surrounding the Ventilating pipe, a pipe p from the chamber to the chimney or cold air shaft, a smoke lpipe located inside of the last mentioned pipe, and a valve located in the pipe leading from the chamber, preventing the admission of air to the rooin through the Ventilating pipe.
