THOMAS T. PEDDY, OF IBIENVILLE, LOUISIANA.

VENTILATOR AND DEFLECTOR.

To all whom it may concern:

Be it known that I, THOMAS T. PEDDY, a citizen of the United States of America, re siding at Bienville, in the parish of Bienville and State of Louisiana, have invented new and useful Improvements in Ventilators and Deflectors, of which the following is a specification.

This invention relates to ventilators and deflectors adapted to be mounted adjacent to the windows of railroad cars for the purpose of deflecting smoke and impurities that have a tendency to enter through open windows, and incidentally to create an outward suction of air current which shall tend to remove the impure and vitiated air from the interior of the car.

This invention, which may be regarded as an improvement on the device for which Letters Patent of the United States, Number 97 3,966, were issued to me on the twentyfifth day of October, 1910, has for its object to provide a shield or deflector of simple and improved construction which may be mounted detachably adjacent to the window frame, the same being capable of exchange from one side to the other, according to the direction in which the car moves.

A further object of the invention is to simplify and improve the construction of the means whereby the deflecting shield is mounted in position.

With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing,-Figure 1 is a perspec tive view showing the invention applied to the side of a car. Fig. 2 is a perspective View, showing the rear side of the shield detached. Fig. 3 is a perspective view of one of the supporting brackets detached. Fig. 4 is a horizontal sectional view taken through the side of the car, and showing a shield in position between two window frames, dotted Specification of Letters Patent.

lines being used to indicate the position of the shield when reversed.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved device consists of a shield or deflector A made preferably of sheet metal, said shield being suitably curved in an approximately horizontal plane, as shown, and provided at the side edges thereof with flanges 1, 1 extending from the top to the bottom edges. The rear side of the shield is provided with plates or brackets which may be in the nature of straps extending transversely across the shield, as shown at 2, or which may be in the nature of plates secured near the side edges, as shown at 2, said plates or straps being provided with downward extending fingers 3 which are slightly spaced from the rear face of the shield.

B designates the site of a railroad car having window frames C, C and intermediate and adjacent wall portions D, D. Secured upon said wall portions in proximity to the window frames are vertical cleats 4 adjacent to which brackets or supporting members E are securely mounted.

It is the purpose of the invention to mount a shield a suitable distance in advance of each window frame, the rear edge of said shield being deflected outwardly from the side of the car so as to be spaced outwardly from the front portion of the frame of the window for which it constitutes a guard or deflector. Accordingly, the supporting members consist of plates 5, the front edges of which are concavely curved outwardly and rearwardly with reference to the direction in which the car moves, as shown at 6, said plates being provided with upwardly and downwardly projectin lugs 7 having apertures for the passage of fastening members such as screws 8. The bracket plates 5 are also provided with apertures 9 adapted to be engaged by the downwardly extending fingers 3 upon the rear side of the shield or deflector. It will be observed that the supporting members E are mounted adjacent to the cleats at at both sides of each window frame so that the shields may be changed from one side to the other according to the direction in which the car moves, the supporting members E at one side being simply inverted with reference to those at the other side of each window, so that the shield may be properly deflected outwardly from the side of the car in whichever direction the latter moves.

Each shield may be provided adjacent to each edge with two or more fingers 3, a corresponding number of supporting members E being provided; usually, however, two fingers will be found to be a suflicient number adjacent to each edge of the shield.

In mounting the improved shield or deflector in position, the fingers 3, 3 adjacent to the front edge of the shield are engaged with the apertures 9 in the plates or brackets 6 of the supporting member E which are se cured adjacent to a cleat 4 in advance of the frame of the window which is to be guarded. The shield, which extends outwardly and rearwardly, will thus terminate approximately in alinement with the front portion of the frame of the window that is to be guarded, and when the train is in motion the air displaced by the deflector will ob viously rush in an outward direction from the open car window in front of which the deflector is located, and the formation of a partial vacuum behind the deflector which is due to the suction thus created will cause an out-rush of air from the car through the open window, thereby thoroughly ventilating the car. Not only will the entrance of cinders, smoke and the like be effectually prevented by this invention, but thorough and absolute ventilation will be promoted in a most efficient manner. In smoking compartments the tobacco smoke will be carried out, instead of being permitted to remain and to taint the upholstery and furnishings of the car, and noxious odors arising from any source, as in dining cars and the like, will likewise be effectually disposed of. When the car has reached the end of the line and is to travel in an opposite direction, the shields or ventilators may be readily lifted from their supports and adjusted or mounted upon the oppositely disposed supporting brackets. It will be noticed that the flanges l at the side edges of the shield will engage between the supporting brackets and the cleats t, said flanges lying in close proximity to and abutting upon said cleats, whereby the shields are very materially strengthened and reinforced.

This invention, as will be seen from the foregoing description, is not only simple in the extreme and capable of being produced at a small expense, but the improved shield and its appurtenances may be readily mounted upon railroad cars of ordinary construction without alteration or recon struction. The shields may, as stated, be made of sheet metal, being sufficiently reinforced by the straps 2 when the latter are extended entirely across the rear sides thereof, said straps being made of cast or wrought metal, as may be preferred. When the said straps are not extended entirely across the shields, other reinforcements may be used, if desired. Vertically the shields are reinforced by the flanges l at the side edges thereof, said flanges serving also to guide the shields when they are being placed in position and to strongly reinforce them while in use. Practical tests have proven this invention to be thoroughly effective for the purposes for which it is provided.

Having thus described the invention, what is claimed as new, is

1. A railroad car having window frames, vertically disposed cleats adjacent to said frames, supporting members secured adjacent to and slightly spaced from the cleats, and a deflecting shield connected detachably with the supporting members and having a flange engaging the rear edge of one of the cleats and lying between and simultaneously engaging and held by such cleat and the proximate supporting members.

2. A railroad car having window frames, vertically disposed cleats adjacent to said frames, supporting members secured adjacent to and slightly spaced from the cleats, said supporting members including apertured plates or bracket members having curved front edges extending outwardly and rearwardly from the car body, and a deflecting shield provided upon the rear side thereof with members having downwardly extending fingers adapted to engage the apertured brackets, and said shield being provided with a flange engaging and securely held between the rear edge of one of the vertical cleats and .the adjoining supporting members.

3. A railroad car having window frames, vertically disposed cleats adjacent to said frames, supporting devices adjacent to and spaced from the cleats, said supporting devices including apertured plates having upwardly and downwardly extending lugs provided with apertures for the passage of securing members, said plates being formed with edges curved to project outwardly from the body of the car, and a curved deflecting shield engaging the curved edges of the supporting plates and provided upon its rear side with fingers spaced from the rear face of the shield and adapted to engage the apertured supporting members.

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