HEATING APPARATUS.

Application filed November 19, 1907.

T 0 all whom it may concern:

Be it known that I, Tnoinis T. Hossacx, a citizen of the United States, residing at Oil City, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Heating Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in heating apparatus, and more particularly to the type in which fluid. fuel, such for instance as natural gas, is employed.

An object of the invention is to provide a heating apparatus which will so promote and improve the combustion that sweating or the deposit of condensed vapor on the walls or other cool surfaces will be largely eliminated. This sweating has heretofore made necessary the employment of a flue communicating with the open air. However, this method is objectionable in that much heat escapes through the fine, and the heating apparatus is rendered stationary, that is, not readily movable about a room.

The employment of a flue has also been necessitated from the objectionable odors of burned products escaping from fluid fuel heating apparatus, and it is one of the objects of the present invention to deliver the heated air in a condition substantially free from odor and possessing the requisite proportion of oxygen for imparting the desirable freshness found usually only in the open air.

With these and other objects which will be obvious in part and in part hereinafter explained, the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawin s:Figure 1 is a side elevation of one embodiment of the present invention. Fig. 2 is a central, vertical section of the same.

Referring to the drawing by numerals, 1 indicates the body of a heating apparatus which so far as the present invention is concerned may have any transverse and longitudinal contour. For the purpose of illustration, I have shown a cylindrical hollow body within which is disposed the fluid fuel burner 2 which obviously is only representative of any combustion apparatus, the walls of the Specification of Letters Patent.

body 1 constituting the combustion chamber. The upper end of the body 1 is partly covered by a ap 3 of any desired type, formed preferably with a central opening 4. The cover 3 may be attached to the body portion 1 in any preferred manner, as for instance by a depending annular llange 5 extending into the body 1. and connected therewith by bolts, rivets or other suitable attaching means. Rising from the cap 3 at preferably diametrically opposite points are standards 6 connected by a transverse brace or bar 7, in which is journaled the upper end of a vertical, centrally disposed shaft 8 which extends throughout the length of the body portion 1 and is stepped at its lower end in a suitable bearing 9, sustained by a spider 10 fixed to the supports 11 of the body portion 1. The spider 10 obviously may be made of any shape preferred and is preferably formed with relatively large open areas for permitting the ready admission of air, and to insure the free intake of large volumes of air I preferably provide apertures 1'2 in the walls of the body portion 1 beneath the burner 2.

Fixed to the shaft 8 preferably above the apertures 12 and beneath and contiguous to the burner 2 is a fan 13. The fan 13 consists of radial blades set preferably at relatively high pitch, for instance forty-live degrees, and any desired number of blades may be employed, but for illustration I have shown only four. Fixed to the shaft 8 above the burner 2 is a similar fan 1 1 with similarly disposed blades, the blades of both fans being set for the fans to revolve in the same direction. Beneath the cover 3 and above the fan 14 is arranged a power wheel 15 which is fixed to the shaft 8 and provided with a greater number of blades than either of the fans 13 or 14, the blades of the power wheel 15 being preferably set at a considerably less pitch than the blades of the fan 14. A wheel 16, similar in construction and arrangement to the wheel 15, is fixed to the shaft 8 above the cover 3 and, as is obvious from the drawing, each of the wheels 15 and 16 is of greater diameter than the diameter of the opening 4. The blades of wheels 15 and 16 are set to revolve in the same direction as fans 18 and 14 when actuated by an upwardly moving air current.

In operation, the burner 2 is supplied from a suitable fluid fuel mixer with the requisite proportion of air and gas, and the combustion of the fuel heating the air within the body 1 causes such air to rise within such body and pass the power wheel 15 and out through the opening 4 past the wheel 16. It is to be noted that the opening 4 being of less diameter than the body 1 and also of less diameter than wheel 16 causes a decrease in the diameter of the discharging volume of air and proportionally increased velocity in the flow of the air upwardly. The air discharging through opening 4 expands as it passes beyond the cover 3, and the size of the power wheel 1 6 is proportioned and the wheel positioned relative to the cover, such that the circumference of the discharging volume of air as it arrives at the power wheel will not exceed the circumference of the wheel 16, and said wheel will therefore be subjected to the force of the full blast of air rising from the body 1. t is to be noted that the fans 13 and 14 are preferably constructed with their blades contiguous to the inner surface of the walls of the body portion 1, so that when the said fans revolve, they of necessity, agitate those areas of otherwise dead atmosphere within the body portion 1 which do not fall directly in the line of draft from the openings in the bottom of the body portion through the burner 2 and up through the opening 4, and this agitation in practice insures not only a substantially perfect combustion, consuming all carbon products, but serves to so thoroughly intermix the atmosphere passing through the body portion with the heated products from the burner as to cause the discharging column of air to contain the requisite constituents producing a substantially pure air. The rising column of air, of course, revolves the power wheels 15 and 16 with increased rapidity as the heat from the burner 2 gradually raises the temperature of the body 1, so that the mixing fans 13 and 14 increase in their speed of revolution in proportion to the ratio of the capacity of the burner, and the desired pure, clean heated air is discharged from the body 1 regardless of the caloric value of the fuel at the burner 2, differences in the caloric value of fuel employed producing differences only in the heat radiation and not in the purity of the heated air.

In contemplating the present invention as means for affording more eflicient combustion, the motor wheels 15 and 16 may be looked upon as fans or agitators, and such fans with the fans 13 and 14 and their connections afford intertransmission of power for breaking up the otherwise natural air currents. Obviously the number of motor wheels and fans employed may be varied and their size and relative proportions altered as found best ada ted for the particular heating apparatus to w ich they may be applied.

What I claim is 1. In a heating apparatus, the combination of a stove body, formed with an air inlet at its lower portion and with a discharge opening at the top, a gas burner situated in the lower portion of the stove body, an agitator fan situated immediately below said burner and contiguous thereto, and an agitator fan situated within the stove body between the burner and the discharge opening, the two fans being operatively connected to each other.

2. In a heating apparatus, the combination of a stove body formed with an air inlet at its lower portion and with a discharge opening at its upper portion, a gas burner situated in the lower portion of the stove body above the inlet, a rotary agitator fan situated immediately below said burner, the burner being formed to offer but little resistance to the flow of gases through said stove body, and the space between the burner and the fan being substantially unobstructed, and a rotary motor wheel situated within the stove body between the burner and the discharge opening, the fan and motor wheel being operatively connected to each other.

3. In a heating apparatus, the combination of a stove body formed with an air inlet at its lower portion and with a discharge opening at its upper portion, a gas burner situated in the lower portion of the stove body above the inlet, an agitator fan situated immediately below the burner and contiguous thereto, the burner being formed to offer but little resistance to the flow of gases through said stove body, and the space between the burner and fan being substantially unobstructed, a motor situated in the line of discharge of products from said burner and adapted to be actuated by the gaseous current passing through the stove body, and means operatively connecting the fan and motor.

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