SIDEWALK-VENTILA TOR.

Specification of Letters Patent.

Patented Aug. 18, 1908.

Application filed October 8, 1907. Serial No. 396,424.

T 0 all whom it may concern:

Be it known that I, MARTIN CARROLL, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Sidewalk-Ventilators, of which the following is a specification.

My invention relates to improvements in sidewalk ventilators.

The object of my invention is to provide an improved form of sidewalk ventilator by which air and light may be readily admitted to the area below the sidewalk, novel means being provided by which, in stormy weather,

water and dirt may be prevented from entering the area through the ventilator.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings illustrative of my invention-Figure 1 is a perspective view of my improved sidewalk ventilator as it is mounted in a concrete pavement, a portion of the top of the ventilator being broken away. Fig. 2 is a vertical sectional View, taken transversely across the ventilator on the dotted line ab of Fig. 3. Fig. 3 is a cross section taken on the dotted line ef of Fig. 2. Fig. 4 is a vertical sectional view taken on the dotted line cd of Fig. 2. Fig. 5 is a view similar to Fig. 2 the closure for the ventilating openings being shown in the closed position in Fig. 2 and in the open position in Fig. 5.

Similar characters of reference denote similar parts.

The ventilator comprises preferably, a rectangular, horizontal hollow body provided with a closed top 1 and vertical side walls 2. The top 1 may be provided with translucent glass plates 3 embedded horizontally in cement or concrete 4 which is supported by horizontal rods 5, which in turn rest at their ends upon horizontal flanges 6 provided in the top 1 and extending along the sides of a rectangular opening 7 provided in the top of the body 1. One or all of the side walls 2 are provided each with one or more transverse .incline downwardly and outwardly in the same plane, so that water entering the openings S will run outwardly instead of into the area under the sidewalk. Extending transversely across the openings 8 upon the upper sides and adjacent the inner edges of the flanges 9 are provided flanges 11, each of which extends vertically in a corresponding longitudinal groove, provided in the lower side of a closure 12 secured by hinges 13 to the inner side of the flange 9. The closure 12 is preferably in the form of a quarter round, the flat side of which, provided with the groove fitting the flange 11, rests upon the upper side of the flange 9 when the closure 12 is in the closed position shown in solid lines in Figs. 3 and 4.

posed at the inner sides of curved screens 14 extending one across the inner end of each ventilating opening 8. One closure 12 is shown in the drawings. If other closures are employed they are constructed in the same manner as the one illustrated.

Each closure on the side which is the inner side when the closure is in the closed position, is provided with a hand hold, such as a hook 15, by which the closure may be swung to and from the closed position. The closure 12, when in the closed position, serves as a support which prevents the screen 14 from being inwardly bent by sticks or other objects which may be accidentally or otherwise inserted through the openings 8. The closure 12 is preferably provided on its inner side with a depression 16 in which the head of the hook 15 is located. Such disposal of the hook 15 lessens its liability to injury.

The underside of the body of the ventilator is preferably provided with four downwardly extending flanges 17, joined at their respective ends to form a rectangle and which, when embedded in the concrete 18, forming the pavement, prevent lateral movement of the ventilator. When the ventilator is set in the concrete 18, the upper sides of the flanges 10 are preferably flush with the upper side of the concrete pavement 18.

Various modifications of my invention within the scope of the appended claims may be made without departing from its spirit.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1. A sidewalk ventilator having a horizontal, hollow body closed at the top and having a ventilating opening in one side wall, a horizontal flange extending outwardly from said wall the upper side of said flange and the lower side of said opening inclining outwardly and downwardly in the same plane,

and a hinged closure for the inner end of said opening.

2. A sidewalk ventilator having a horizontal, hollow body closed at the top and having a ventilating opening in one side wall, a screen across the inner end of said opening, a hinged closure for the inner end of said opening, and a horizontal flange extending outwardly from said wall the upper side of said thereon when in the closed position.

4. A sidewalk ventilator having a horizontal, hollow body closed at the top and having a ventilating opening in one side wall, a horizontal flange extendin inwardly from said wall, the upper side 0? said flange and the lower side of said- 0 ening being in the same plane, and a vertica flange on the upper side of said inwardly extending flange and extending across said opening.

5. A sidewalk ventilator having a horizontal, hollow body closed at the top and having a ventilating opening in one side wall, a horizontal flange extending inwardly from said wall, the up er side of said flange and the lower side 0' said opening inclining downward and outward in the same plane, and a vertical flange extending across said opening upon the upper side of said inwardly extending flange.

6. A sidewalk ventilator having a horizontal, hollow body closed at the top and having a ventilating opening in one side wall, a horizontal flange extending inwardly from said wall, the upper side of said flange and the lower side or said opening inclining in the same plane downwardly and outwardly, a vertical flange extending across said opening upon the upper side of said inwardly extenda screen across said opening.

ing flange, and a closure for said opening hinged to said inwardly extending flange.

7. A sidewalk ventilator having a horizontal, hollow body closed at the top and having a ventilating opening in one side wall, a hori zontal flange extending inwardly from said wall, the upper side of said flange and the lower side of said opening being in the same plane, a verticalflange extending across said opening upon the upper side of said inwardly extending flange, a closure for said opening hinged to said inwardly extending flange, and

8. A sidewalk ventilator having a horizontal, hollow body closed at the top and having a ventilating opening in one side wall, a horizontal flange extending inwardly from said wall, a horizontal. flange extending outwardly from said wall the up er sides of said flanges and the lower side of said opening inclining downwardly and outwardly in the same plane, and a closure for the inner end of said opening hinged to said inwardly extending flange which supports said closure in the closed position.

9. A sidewalk ventilator having a horizontal,.hollow body closed at the top and having a ventilating opening in one side wall, a horiwall, a horizontal flange extending outwardly from said wall, the upper sides of said flanges and the lower side of said opening inclining downwardly and outwardly in the same plane, a vertical flange extending across said opening upon the upper side of the inwardly extending flange, and a closure for the inner end of said opening hin ed to said inwardly extending flange, said c osure MARTIN CARROLL.
