HENRY B. MEARS, OF PHILADELPHIA, PENNSYLVANIA.

CAR-WINDOW DEFLJECTOR.

SPECIFICATION formingpart of Letters Patent No. 272,738, dated February 20, 1883.

Application filed April 25, 1882. (No model.)

To all whom t't may concern Be it known that I, HENRY B. MEARS, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Dust and Cinder Deflectors and Ventilators for Railroad- (Jar Windows, of which the following is a full, clear, and exact description.

Theobject ot' myinvention is to provide the windows of railroad-cars with dust and cinder deflectors that can he moved in and out of position readily and conveniently, and which, when not in use. shall be out of the way and protected from injury.

The nature of my invention consists in the combination and arrangement of parts, substantially as hereinafter more fully set forth.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a portion of the side of a car having the improved dust and cinder deflectors applied. Fig. 2 is a. horizontal section at the side of one window-frame, and Fig. 3 is a perspective view of the operating-crank used for moving back the deflectors.

A represents the side of a car, and B B are the windows, fitted with sliding sashes a, as The dust and cinder deflectors are fitted at both sides of each window-frame in a straight line, for movement in and out of the space between the inner and outer sides of the cars, as follows. i

b is the elliptic or how spring, attached at each side to vertical bars 0 c. that are fitted to slide between the parallel guide-bars d d.

e e are strips of suitable width, attached rigidly to the slide-bars c c; and ffare the dust and cinder deflectors or blinds, hinged to the outer edges of the strips as by springhinges g g of any suitable character. The window-jambs are slotted between the stopstrips of the sash to allow projection of the deflectors into the opening when the sash is raised, and the deflectors are to be equal in length to the distance which the sash opens. The deflectors are moved by the pressure of the spring entirely out of the slot, so that the outer edges of the strips 6 shall project slightly, and the (Ir-flBPIOIS thus left free to be turned outward to the extent desired by the action of their coil-springs. The strips serve to sustain the deflectors rigidly in th ir outward position. Their upperends are formed with rabhets c, and the upper ends of the deflectors are correspondingly rabbeted atf. so that the sashes can be dropped slightly below the upper ends of the deflectors. At their lower ends the deflectors take against stop-blocks h, fixed on the window-sills, which limit their movement and close the space between the blinds and sills.

To move the deflectors inward and retain them, I provide levers i, pivoted at one end to the inside of thejamb', and hearing at their upper ends upon the vertical bars 0 0, the ends being provided with friction-rollers. Thejointpins of the levers are formed to receive a key, I, which is inserted from the inside of the car through an opening provided for the purpose. To withdraw the deflector, the sash is to be raised to clear the slot, and the lever then turned with the key, which forces the whole apparatus into the space. This compresses the spring, so that the deflectors will be thrown or forced out thereby when required for use.

The deflectors on the sides of the windows toward the head ofthe train only are required for use, and those in the sides toward the rear of the train must be held in by turning the key toward the center of the space.

With cars not having sufficient space between the windows to admit of the placing of straight line they will be placed side by side across the space, with the vertical bars 0 fastened to the inner andopposite sides of the jambs, the slots in thejambs being cut to correspond, so as to allow the deflectorsfto pass out on opposite sides. This allows the application of the deflectors and parts to very narrow spaces.

It will be understood that the deflectors are automatically turned by the coil-springs 9 out of the windows on the sides toward the head of the train at an oblique angle, and extending toward the rear of the train. The windows in the rabbets e of strips 0 and the rabbets j" in the upper ends of the deflectors, the deflectors are held securely in the oblique position. The position of the deflectors at the angle described with their tops above the bottoms of the windows and their bottoms restthe working parts of the two deflectors in a being then lowered so that their bottoms rest I ing against the stop-blocks h, effectually prevents dust and einders from entering the open windows, and by the exhaustion of air an outward draft will be created, which will serve to ventilate the cars.

The. deflectors. when not in use, and having the levers iturned back again t the jambs, will press on the edges of the window-sashes, and thus serve as means for holding the window-sashes in any desired position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The spring I), slide-bars c e, and hinged blind or deflectorf, combined with a car having a slotted wiudow-janib and astop, substantially as described,for operation as specified.

2. The lever t and key I, in combination with with rabbet e, the hinged deflector f, pro- 0 vided with rabbet f, and sliding sash a, substantially as described.
