' VENTI'LATING nE vrcE.

Specification of Letters Patent.

Patented Feb. v, 1922.

Application filed September 20, 1920. Serial No. 411,496.

To all whom it may concern:

Beit known that I, JAMES M. EDWARDS, a citizen of the United States, and resident of the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Ventilating Devices, of which the following is a specification. j V

This invention relates to ventilating devices, and has for its primaryobject to provide inexpensive and effective means for regulating and equalizing the temperature of a room; 7

The present invention in one embodiment thereof comprehends the provision ofv means adapted for association with a suitable heat supply device'such as a gas or oil burner, or a radiator, the said device "being provided with a separate inlet passage for relatively cold air adjacent to the floor of the room, or from the exterior of the building, and also with means for thoroughly mixing the currents of cold and'warm air and disseminating the same into the room adjacent to the floor surface.

In general the invention-contemplates the provision of a device for the above purpose which may. be constructed. at relatively small cost, will occupy a minimum of space, and in the successful operation of which little or no additional expense will be involved. p r

With the above and other objects in view, the invention consists in the improved temperature equalizing orregulating' device as Will be hereinaftermore fully described, illustrated the accompanying drawings, and subsequently incorporated in the'subjoined claims.

In the drawlngs, wherein I have disclosed several desirable embodiments of the 'invention, and in which similar reference characters designate corresponding parts throughout the several views:

Figure 1 is a frontelevation partly in section, illustrating one embodiment of my invention.

Figure 2 is a vertical transverse section showing the device arranged vin operative position with respect to a radiator.

Figure'3 'is a section taken on the line 3- -3 of Figure 2, and,

Figure 4 is a view similar to Figure 2 illustrating a slightly modified form of the device.

Referring in detail to the drawings, 5

designates a casing preferably constructed of sheetmetal, and which may be of any de sired size and dimensions. This casing is provided with front and rear walls 6 and 7 respectively, and an intermediate vertically disposed partition wall 8 extending between the opposite side walls of the casing. The front wall 6 is provided in its lower portion with the spaced openings 9 and 10 respec tively, while the rear wall 7 terminates at its lower edge above and in spaced relation to thei bottom wall of the casing to provide an outlet opening 11 extending across the entire width of the casing; V relatively short vertically disposed transverse partition wall 12extends between the front wall 6 and the partition wall 8 of the casing, and is located between the openings 9 and 10. The space above this transverse partition wall and between the front wall6 and the wall 8 provides a mix ing chamber 13. I,

The partition wall 8 at the rear sideof the mixing chamber is provided with an opening 14. A fan 15 is mounted between the wall 8 and the rear wall of the casing in axial alignment with this opening. This fan maybe operated by any suitable means, and may either be mechanically driven, or operated automatically such cases Where a sufiiciently strong current of heated or cold alr 1s available forthe purpose of driving said fan.

In the operation of the invention as above explained, a gas or oil burner may be arranged within or adjacent to the opening 9 in. the frontwall of the casing, as indicated n Figure n th eated air i g a o e the partition 12 will draw cold air through the opening 9 from the floor surface of the room, and these hot and cold air currents are thoroughly mixed in the chamber 13 from which they. pass through the opening 14 in the partition wall 8, and are driven downwardly by the fan 15 and through the outlet opening 11' at the rear side of the casing,

where the heated air is distributed over the surface of the floor. I

As is well known, in all apparatus now used for the heating of rooms or apartmentsthere is a relatively high temperature adj acent to the ceiling of the room, while at the floor surface the temperature is many degrees lower. Owing to the tendency of the heated air'to rise from the radiator or other heating apparatus, the occupant of the room often suffers actual discomfort owing to the fact that the air adjacent to the floor surface is practically unheated. By means of my present invention it will be seen that this deficiecncy in present heating apparatus is entirely overcome and the cold air adjacent to the floor is thoroughly mixed with the heated air current, and a column ofair of equalized temperature is then discharged over the floor surface.

As shown in Figure 2, the invention may be employed in connection with the ordinary steam or hot water heating radiator which I have indicated at 16, and in such case the opening 8 in the front wall of thecasing 5 is arranged closely adjacent to the radiator columns, while the other opening 9, constituting the cold air inlet, is exposed beyondthe end of the radiator. Of course it is manifest that the device might be made in elongated form, and hot air and cold air receiving openings of greater size provided.

r In Figure 4 of the drawings I have indicated a slightly modified embodiment of the invention, wherein a pipe or conduit 17 is connected to the front side of the casing 5 in line withthe opening 9. This pipe receives cold air exteriorly of the room, and is provided with asuitable regulating valve 18.

In the operation of this form of the device the air is not drawn from the floor surface through the mixing chamber, but exterior cold air is mixed with the current of heated air from the radiatoror other source of heat. This embodiment of the invention is desirable where a very high degree of heat is available, so that a constant supply of heated fresh air instead of a partially vitiated air is constantly released into the room. 7

From the foregoing description considered in connection with the accompanying drawings, the construction, manner of operation and several-advantages of the invention will be fully understood. The device is exceedingly simple in. its construction, and can, therefore, e manufactured and sold at nominal cost. a Owing to the fact that no special heating apparatus is necessary, the operating cost will be practically nil. It will be appreciated that a constantly equalized temperature of the air in a room or apartment may be maintained, and the air adjacent to the floor surface will always be substantially thesame 7 temperature as the air at higher elevations.

It will be seen that there is no permanent connection of the device .to the burner, radiator or other heating apparatus, so that it may be readily moved from one room to another.

In the above description and the accompanying drawings, I have described and illustrated several, desirable and practical embodiments of the device, but it is, nevertheless, to be understood that the same is susceptible of a great many modifications in the form, proportion and arrangement of its several parts, and I accordingly reserve the privilege of adopting all such legitimate changes and modifications as may be faily embodied within the spirit and scope of the invention as claimed.

I claim:

1. A device of the character described comprising a casing having spaced openings in one wall thereof, and a central vertical partition extending between its side walls, a transverse partition located between the openings and providing separate hot and cold air inlet passages, said'p'artition terminating below the upper end of said vertical partition, the space above said transverse partition constituting a mixing chamber for the hot and cold air currents, the rear wall of the casing having an outlet opening at its lower end and a fan mounted within the easing to thoroughly mix. the hot and cold air currents and direct the same through said outlet opening.

2. A device of the character; described 7 comprising a casing having hot and coldair inlet openings in its front wall andadjacent to its base, partition walls within said casing forming separate hot and. cold air passages and a mixing chamber, one of said partition walls having an opening therein, the rear wall of the casing being provided with an outlet opening at its lower end, and a mixing fan mounted adjacent to said opening in the partition wall to thoroughly mix the hot and cold air currents and dischargethe same through said outlet'opening.

3. portable ventilating device comprising a casing having means therein providing separate air inlet passages opening at one of their ends through one wall of the casing, said casing also having a mixing chamber with which said passages communicate and an air outlet passage communicating with the mixing chamber and opening through another wall of the casing, the outlet passage having an area substantially equivalent to the combined areas of the. air inlet passages.

4:. A portable ventilating device comprising a substantially rectangular casing having its interior divided by a plurality of partitions into separate hot and cold air inlet passages opening at one of their ends 7 through one side wall of the casingat the lower endthereof, a mixing chamber with which the other ends of said passages. cornmunicate, and. an air outlet passage opening through the Opposite sidewall of said casing at its lower end and extending across substantially the entire width of the casing one ofisaid partitions having an opening therein affording communication between said outlet passage and the mixing chamber.

In testimony whereof I afiix my signature.

I JAMES M. EDWARDS.
