AIR OUTLET DEVICE Filed Aug. 8, 1945 Patented Nov. 28, 1950 UNITED STATES PATENT OFFICE AIR OUTLET DEVICE Friedrich Boner-temp, New York, N. Y., assigninto Anemostat Corporation of America, New York, N. Y., a corporation of Delaware ApplicationAumt 8, 1945, Serial No. 809,515

3 Claims. 1

This invention relates to ventilating apparatus, and has particular reference to improvements in air outlet devices through which air is delivered from air supply ducts into enclosures.

More particularly, the invention relates to an air outlet device especially for, but not limited to, use in delivering heating, cooling or simply ventilating air into relatively narrow enclosures such, for example, as railway cars, motor buses and other land vehicles and the cabins of aircraft, marine vessels and the like.

In order to avoid discomfort to occupants of an enclosure such as mentioned it is necessary that air for heating, cooling or simply ventilating purposes be delivered into the enclosure in some special manner other than in blast form. Moreover, to this end and to the end of securing the greatest benefit from heating, cooling or simply ventilating air delivered into such an enclosure, it usually is necessary that the air be delivered in diflferent manners for said different purposes. At the same time, for the sake of simplicity, economy, conservation of space and other reasons, it is desirable to provide an air outlet device which does not include adjustable parts requiring adjustments to render it suitable for the satisfactory delivery of air for any one of said purposes.

Accordingly, one special and important object of the present invention is to provide an air outlet device which is of simple, inexpensive construction; which is compact and occupies comparatively little space; and which, without including adjustable parts requiring adjustment to adapt it to deliver either heating, cooling or simply ventilating air in a satisfactory manner, is effective to accomplish this purpose because of the novel construction, combination and relationship of its elements.

The present device is of the well known general type including a plurality of open-ended, hollow flaring members spacedapart to provide flaring air passageways therebetween, and in this connection another special and important object of the invention is to connect a plurality of said members together as a unit for unitary installation in and removal from the device, and to advantageously provide readily accessible means,

entirely separate and distinct from the means connecting said plurality of members together as a unit, to enable said unit readily and easily to be installed in and removed from the device.

With the foregoing and other objects in view, which will become more fully apparent as the 2 same consists in'an air outlet device embodying the novel features of construction, combination and arrangement of elements as will be hereinafter more fully described, illustrated in the accompanying drawings and defined in the appended claims.

In the accompanying drawings, 'wherein like characters of reference denote corresponding parts in the different views:

Figure 1 is a central, longitudinal section through an air outlet constructed in accordance with the invention; and

Figure 2 is an end elevation looking toward the outerend of the device.

Referring to the drawings in detail, it will be observed that the present device includes an outer, preferably but not necessarily, cylindrical air supply neck, designated as Ill, and a smaller, preferably but. not necessarily, cylindrical inner air supply neck, designated as i I, disposed preferably, but not necessarily, concentrically, within and spaced from said outer air supply neck.

It will further be observed that a flaring member i2 extends forwardly from the front end of the outer neck I0; that a flaring member I3 extends forwardly from the front end of the inner neck II and is spaced from the flaring member [2 to provide between the same and said flaring member I! an annular flaring passageway a of ring-like form; that the front end portion H. of the flaring member I! is directed inwardly relative to the rear portion of said member to intercept air flowing through said flaring passageway a and to deflect it forwardly from the device, and that, within the flaring member I3, are other annular flaring members l5 and I6 constituting means to intercept air flowing from the inner neck II, to divide it into separate ringlike streams and to deflect it laterally from the device.

The outer neck Ill is connected with an air supply duct A and the neck II' is connected with an air supply duct B separate from the duct A. The air supplied through the duct A may be of one kind, heating air for example, and the air supplied through the duct B may be of a different kind, cooling air for example. Or, if desired, the air supplied through both ducts may be of the same kind, either heating or cooling or simply ventilating air for example. Moreover, air may be supplied through both ducts simultaneously, or, at any given time, air may be supplied through only one of said ducts to the exclusion of any supply of air through the other nature of the invention is better understood, the of said ducts.

3 In any event, the device, together with suitable valve or damper means (not shown) for controlling flow of air to and through the necks l and Il, may be employed to deliver either heating, cooling or simply. ventilating air into a narrow enclosure in a. satisfactory manner with reference to the comfort of occupants of the enclosure.

For example, assuming that the device is mounted at or near the top, and midway or approximately midway between the sides, of a narrow enclosure and that the necks I0 and Ii are connected to separate ducts for supplying heating and cooling air, respectively, it is apparent that by opening one and closing the other of the valve or damper means aforementioned, air for heating purposes may be supplied to the neck iii to the exclusion of any supply of air to the neck II, or that air for cooling purposes may be supplied to the neck i i to the exclusion of any supply of air to the neck Ill.

If air for heating purposes is supplied to the neck i0, it will be caused by the flaring member I3 to flow laterally outward through the flaring passageway a in more or less diffused, ring-like form, to the margin of the device where it will be intercepted by the wall portion [4 of the flaring member l2 and deflected by said wall portion more or less forwardly from the device, depending upon the angularity of said wall portion to the longitudinal axis of the device. It will thus be delivered in non-blast form practically without causing any discomfort to occupants of the enclosure and, at the same time, in directions to afford the occupants of the enclosure the greatest benefit therefrom.

If, on the other hand, air for cooling purposes is supplied to the neck II, it will be divided into separate, ring-like streams and be deflected laterally outward by the members l5 and IS with the result that it will be diffused and be delivered in other than blast form practically without causing any discomfort to occupants of the enclosure and, at the same time, in a manner to afford the occupants of the enclosure the greatest benefit therefrom.

Alternatively, some cooling air may be supplied through the neck |0 simultaneously with supply of some heating air through the neck II, or air solely for heating, cooling or simply ventilating purposes may be supplied simultaneously through both necks l0 and II. In any such case, the respective air streams obviously will intersect and become intermixed and thoroughly diffused in front of and immediately adjacent to the device with the result thatoccupants of the enclosure will not be subjected to any sensation of blast or draft and yet will be afforded the benefit of the air delivered to the enclosure either for cooling, warming or simply ventilating purposes.

The device may include only a single flaring member or any desired plurality of flaring-members within the flaring member l3, and in this connection, if only a single'flaring member is provided within said flaring member l3, it may be either closed or open at its rear end. Likewise, if a plurality of flaring members are provided within the flaring member 13, the smaller or innermost of said plurality of flaring members may be either closed or open at its rear end. On the other hand, all other of said plurality of flaring members would be open at both ends.

A feature of the invention, applicable to any outlet device of the general type illustrated and described, is that the flaring members inwardly of the flaring member I! are connected together as a unit for unitary assembly with and disassembly from said flaring member if, and that means separate from the means connecting said flaring members together as a unitis advantageously employed for removably mounting said unit in assembly with said flaring member It. In this connection it will'be noted that the flaring members inwardly of the flaring member I! are connected together as a unit by struts l1 and that said unit is mounted within the flaring member l2 by bolts ll passing through the flaring members I! and I8 and through spacing thimbles I9 interposed between said flaring members. It will further be noted that the bolts II are located where they are readily accessible from the front of the device so that assembly and disassembly of the flaring member unit with and from the flaring member I! is greatly facilitated, especially as compared with extending the struts l'l beyond the flaring member II and utilizing the extensions of said struts as means for removably mounting the flaring member unit within the flaring member i2.

From the foregoing description considered in connection with the accompanying drawing it is believed that the construction and operation of the device will be clear and its advantages appreciated. It is desired to point out, however, that while only a single, specific embodiment of the invention has been illustrated and described, the same is readily capable of embodiment in specifically different structural forms within its spirit and scope as defined in the appended claims.

I claim:

1. Air outlet means comprising two separate air supply ducts to be used, one for the supply of air of one kind and the other for the supply of air of a different kind, the outlet end portion of one of said ducts being disposed within the outlet end portion of the other of said ducts, a pair of members connected to the outlet end portions of said ducts, respectively, and extending laterally therefrom in spaced apart relationship to each other to provide therebetween an air outlet passageway leading laterally from the outer of said ducts, means to cause air delivered from the outer duct through said passageway to be directed forwardly from said passageway, and means to cause air delivered from the inner duct to be deflected laterally out,- ward therefrom.

2. Air outlet means comprising two separate air supply ducts to be used, one for the supply of air of one kind and the other for the supply of air of a different kind, the outlet end portion of one of said ducts being disposed within the outlet end portion of the other of said ducts,

means including an air deflecting member disposed in the path of flow of air discharged from said outer duct to cause air delivered from the outer of said ducts to be deflected first laterally outward and then forwardly therefrom, and means including an air deflecting member mounted in front of and spaced from the discharge end of said inner duct to cause air delivered from the inner of said ducts to be deflected laterally outward therefrom,

3. Air outlet means comprising two separate air supply ducts to be used, one for the supply of air of one kind and the other for supply of air of a different kind, the outlet end portion of one of said ducts being disposed within the outlet end portion of the other of said ducts, a pair of flaring members. connected to the outlet end portions of said ducts, respectively, and extending in spaced relationship to each other to provide therebetween an air outlet passageway leading laterally outward from the outer of said ducts, air deflector means adjacent to the forward end of the outer of said members to cause air delivered from the outer of said ducts through said passageway to be directed forwardly from said passageway, and air deflector means mounted in front of the outlet end of the inner duct to cause air delivered from said inner duct to be deflected laterally outward therefrom.
