5 Claims.

The instant invention relates to certain new and useful improvements in ventilating devices and apparatuses such as are used for ventilating and de-humidifying in buildings such, for example, as homes and the like, but is primarily adapted to be used in warehouses, garages, barns, chicken and hog houses, corn cribs, and the like.

By way of introduction, it is to be pointed out that the invention herein disclosed and claimed appertains, in particular, to a similarly constructed and functioning ventilator covered in our copending application, Serial No. 574.382, filed on January 24, 1945, now Patent 2,433,544. More specifically, the improvements have to do with an auxiliary air intake arrangement forming a part of a conduit, which conduit is divided into coacting ducts, one for purposes of picking up and delivering atmospheric air into the barn or other enclosure, and the other of which is adapted to suck the air out of the enclosure space and to carry it, under pressure, to the exterior of the enclosure.

Being an improvement upon the structure in the copending application, the structure utilized bears certain basic resemblances thereto in that we utilize a conduit which is expressly made in a manner to suitably handle the moist, foul air discharge, this being governed by screened intake openings in one duct of the conduit, the latter duct having a motor-driven fan unit located therein and suitably sized to handle the movement of air necessary.

Stated with greater particularity, we have evolved and produced a simple and expedient wooden, or equivalent conduit arrangement which spans the upper space in the enclosure at a point below the ceiling and which opens through one end of the enclosure or building for purposes of taking in atmospheric air, and opens through another end of the'building at its opposite end for purposes of scavenging the air, whereby to set up a suitablecirculation to satisfactorily achieve the ends sought.

Other objects, features and advantages of the invention will become more readily apparent from the following description and the accompanying illustrative. drawings.

In the drawings, wherein like numerals are employed to designate like views:

Figure l is a perspective view ofa barn, building or other enclosure provided with ventilating means constructed in accordance with the principles of the present invention.

Figure 2 is a central longitudinal sectional view of the same structure, this to bring out the details of construction and the arrangement of such details.

Figures 3 and 4 are transverse sectional views parts throughout the taken on the planes of the lines 3--3 and 4-4, respectively: of Figure 2.

By way of further explanation, it is to be pointed out that the invention is applicable to any space in which the same might be satisfactorily employed for de-humidifying and ventilating purposes. In the drawings, it is sufficient to simply show what may be called a building or perhaps a barn A, with parallel side walls B-G, end walls D--E, and roof F. Considered as a unit, the invention is, broadly, a wooden or equivalent conduit 6. The over-all length of the conduit corresponds to the length of the space in which it is located. In the instant situation, it is shown positioned in the upper area of a barn just beneath the ceiling. As brought out in Figure 4, the conduit comprises top and bottom boards 1 and 8 and side boards 9 and I0, these being secured together in box-like relationship, and reinforcing strips of wood or the like ll being arranged for assembling and securing the parts together. A central partition [2 serves to define upper and lower main and auxiliary ducts l3 and I4, respectively. Observing the ducts, it will be noted that the main duct is closed at the righthand end, as indicated at [5, and at the opposite end is enlarged and flared into funnel-shaped form, as at It. Here it is provided with an extension sleeve I 1 whose discharge end extends through an opening in the end wall D, as shown in Figure 2, and is flanged and secured in place as at I8. This sleeve serves as an adapter housing for a stand or bracket H! which serves to support a suitable electric motor 20 for driving a suction or exhaust fan 2|. The fan is located within the confines of the sleeve and the outer end of the sleeve is provided with freely hinged louvers '22. These louvers are normally closed. When, however, the fan is in operation, the louvers are swung to open position and the accumulated air and moisture in the duct or space I3 is scavenged and discharged into the atmosphere on the outside of the building. It will be noted that the auxiliary air intake duct is somewhat shorter in length than the main duct [3,

that it opens through the wall E at the righthand end, where it is provided with an intake hood of downturned visor-like form', as indicated at 22. This auxiliary duct I4 is closed at the left-hand end, as indicated at 23. Also, this duct is provided with air intake holes or ports 24 covered by suitable screens 25. The other or main duct I3 is provided with intake openings 26 covered by suitable screens 21.

In operation, it is obvious that the suction created Within the space of the barn produces a pull on the screened intake ports 24. Thus, air is sucked from the exterior of the barn, as shown by the arrows in Figure 1. The incoming air escapes through the screened openings 24 and selection and arrangement of details which go to make up such conduit.

In view of the foregoing description taken in conjunction with the accompanying drawings, it

is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though we have herein shown and described a preferred embodim'entof our invention that the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and within the scope of the appended claims.

We claim:

1. In a structure of the class described, in combination, a building construction defining a room, storage or equivalent space, a horizontally arranged conduit open at opposite ends and having said ends in communication with openings in opposite end walls of the building construction, a partition in and extending longitudinally of said conduit and dividing the latter into separate intake and exhaust passages, the latter having individual screened openings, the inlet end of the air intake passage being provided with a downturned hood-like adapter located exteriorly of said building construction, the discharge end or the exhaust passage being enlarged and provided with a sleeve having pressure-opened normally-closed louvers therein, and an electric motor driven fan mounted in said sleeve, whereby to create a suction within said space, to suck foul and moist air from said space and to exhaust same to the atmosphere and to create sufiicient suction on the screened openings in the intake passage to facilitate the delivery of air into the latter.

2. Ventilating and de-hum'idifying means for Warehouses, barns and the like comprising, in

combination, a building embodying a room, storage or equivalent space and including a ceiling, a horizontally situated conduit supported for use in said space close to, but spaced from, said ceiling and having its opposite ends open and opening through opposite end walls of said building construction, a partition in and extending longitudinally of said conduit and dividing the latter into a lower fresh-air intake and distributing passage, and an upper foul air exhausting passage, the intake passage being closed at its inner end and of a cross-section less than the crosssection of the exhausting passage, the inlet end of said air intake passage being provided with a downturned air intake hood, the latter located exteriorly of the adjacent building wall, the discharge end of the exhausting passage being gradually enlarged in a direction toward the adjacent building wall, a flanged sleeve fitted into an opening in the last named wall and in communicative connection with the adjacent enlarged end of said exhausting passage, an electric motor driven fan mounted in said sleeve, the underside of said air intake passage being provided with longitudinally spaced ports and individual screens covering said ports, the top side of said exhausting passage being also provided with ports covered by individual screens.
