SPECIFICATION forming part of Letters Patent No. 613,354, dated November 1, 1898.

Application filed August '7, 1897- Serial No. 647,451. (No model.)

To a. whom, it may concern:

Be it known that we, FRANZ BURGER and HENRY M. WILLIAMS, citizens of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Ventilators, of which the following is a specification.

This invention relates to certain new and useful improvements in ventilating apparatus for buildings and conveyances of all kinds. It is more particularly adapted, however, for use in connection with street and railway cars, having for its object to provide simple and efficient means whereby fresh air is introduced into the car and the vitiated air discharged therefrom.

WVith this object in view the invention consists in the novel construction, combination, and arrangement of the parts hereinafter more particularly described.

In the accompanying drawings, forming a part of the specification, and in which like letters and figures of reference indicate corresponding parts, Figure 1 is a sectional view of a portion of a Window and its frame with the ventilator applied thereto. Fig. 2 is a horizontal sectional view on the line as m. Fig. 3 is a vertical sectional view on the line y 1 looking in the direction of the arrow, Fig. 1.

Referring more particularly to the drawings, A designates the ventilator, which may be secured in the side wall of a car or building; but preferably it is arranged, as shown, in the lower bar of a window-sash 1. This sash-bar is provided with an opening extending entirely through it, and into this opening is fitted a metallic thimble 2. Within the thimble 2 is fitted to move longitudinally a sleeve 3, having its outer end open and provided with an inner closed end formed with a head 4, and near said inner end the sleeve is formed with lateral openings 5.

Secured to the inner face of the sash-bar is a semicircular casing 6, having its lower end opento permit ready access to the inner headed end of the sleeve 3; which is partially inclosed by the casing. The vertical wall of this casing serves as a stop for limiting the withdrawal of the sleeve 3 from the thimble 2, and upon the inside face of the wall is formed a segmental bearing 7, against which the upper edge of the head 4 rests in contact when the sleeve is fully withdrawn from the thimble The casing 6, in addition to serving as a shield for the sleeve 3, also serves as a fingerpiece by means of which the window may be lifted, and if this is efiected while the sleeve 8 is withdrawn from the thimble 2 the bending of the sleeve will be prevented by the segmental bearing 7, with which its head is in contact.

Upon the outer face of the sash-bar is a second casing 8, which partially incloses the outer end of the sleeve 3 and has its lower bring its head into contact with the vertical wall and segmental bearing of the casing 6, thereby uncovering the lateral openings 5 and withdrawing its open end from the recess 9. Air then enters the lower open side of the casing 8, any dust or cinders carried thereby'striking the upper closed side of the casing, dropping by gravity back through the lower side thereof. From the interiorof the casing 8 the air enters the open end of the sleeve 3 and flows therethrough and out through the lateral openings 5 into the casing 6, where it is deflected downward and out through the lower open side into the car.

Without limiting ourselves to the exact construction and arrangement of the parts shown and described, what is claimed is- 1. A ventilator comprising a longitudinallymovable sleeve having an open and a closed end and provided in its side near its closed end with radial openings, an open-sided casing inclosin g one end of the sleeve, and means extending beyond the casing through which the sleeve is operated, substantially as described.

2. The combination with a wall, windowsash, or the like having an opening through it, of a ventilator comprising a sleeve adapted to slide in the opening, and open-sided cas ings inclosing the opposite ends of the sleeve, substantially as described.

3. The combination with a wall, windowsash, or the like having an opening therein, of a ventilator comprising a sleeve adapted to slide in said opening, and an open-sided casing inclosing one end of the sleeve and having a recess for reception of the end of the sleeve, substantially as described.

4. The combination with a window-sash having an opening extending through it, of means for controlling said opening, and a casing upon the exterior of the sash having a downwardly-opening side, said casing communicating with the openin gin the sash, substantially as described,
