VENTI LATOR AND H EATER.

SPECIFIGATION forming part of Letters Patent No. 352,097, dated November 2, 1886.

Application filed February 2, 1856. Serial No. 190,619. (No model.)

To all whom it may concern:

Be it-known that I, RODNEY S. OWEN, a citizen of the United States, at present residing in South Stukely, county'of Shefford, Province of Quebec, Canada, have invented a newand useful Improvement in Ventilators and Heaters,

of which the following is a specification, ref- .erence being had to the annexed drawings,

its distribution in the building; and to this.

end the invention consists in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed out in the claims.

The drum A,which forms the body of the heater, is closed by heads a b, the head u having an inwardly projecting collar, 0, for receiving the stove-pipe d, thehead I) having an outwardly-projecting collar, 0, for receiving the stove-pipe d. Air-fines e extend lengthwise through the drum A,and around the collar c of the lower head of the drum'is formed an annular chamber, f, which communicates with all the flues e, and is provided with a cold-air pipe, B, which leads to the exterior of the building in which the heater is placed.

In the center of the drum A is supported a short length of pipe, 0, axially in line with the pipe dd, but not communicating directly with the pipe. The pipe 0 is supported from the heads of the drum by rods In the pipe 0 is placed a damper, h, whose spindle t extends throughthe sides of the drum A, and one end of the spindle is provided with an eye, j, forming the handle of the damper.

A pipe, is, extending through the bottom of the annular chamber f and upward into one of the tubes E, is closed at the top, and has attached to the bottom thereof a diaphragm-case,

D, formed of two oppositely-arranged cups,'l

clamped together upon the flexible diaphragm m. To the centerof the diaphragm m is secured a rod, 11,,which passes through the lower cup, Z, and is connected with an arm, 0, secured position in the stove-pipe d d, and the coldair pipe B may enter at the bottom of the chamber f, or at the side, as may be required. When the damper his opened, the products of combustion pass from the pipe d directly through the pipe 0 to the pipe d; but when the damper h is turned so as to close the pipe O the products of combustion are compelled to pass outside of the pipe 0 in contact with the flues c. The pipe contains air, and when the heater is cold the air contracts and the diaphragm m is drawn upward, as shown in Fig. 2, closing the damper q in the cold-airpipe B; but when the flues are heated and the air in the pipe is is expanded the diaphragm m is pushed downward bythe expansive force of the air, and acting upon the arm 0 of the damper q, through the rod t, turns the damper into 1 a position parallel with the air-pipe, allowing air to enter the chamber f, whence it passes through the flues 6 into the room, the air being heated in its passage By causing the variations of temperature in the drum A to operate the damper in the coldair pipe I am enabled to regulate the admission of cold air to the room, so that when the drum is cold the cold-air pipe will be automatically shut, thus preventing thewind from blowing into the room through the pipe and throughthe heater; but when the drum A is heated, the damper in the cold-air pipe being always open, air may readily enter.

The air introduced to the room through the heater,being warmer than the air contained by the room, rises and displaces theair in the upper portion of the room, while the foul air in the lower partof the room escapes through the stove with which the heater is connected, or through the, various crevices and openings around the windows and doors.

I am aware that a heating-drum adapted to be connected to a stove-pipe at opposite ends, I

Having thus described my invention,what I claim as new, and desire to secure by Letters 2. The combination, with a drum provided Patent, iswith air-fines and acold-air pipe, of a valve in 1. lhe heating-drum A, having the inwardthe cold-air pipe, a pipe extending into one of :5 ly-projecting collar 0 at its upper end andthe the air-flues and having its upper end closed,

5 outwardly-projecting collar 0 at its lower end, a diaphragm in thelower end of the said pipe, and. provided with the annular chamber f and a connection between the diaphragm and around the collar 0, the air-flues 6, extending the valve, substantially as herein shown and lengthwise through the drum and communidescribed. eating with the annular chamber, and. the cold- RODNEY S.
