SPECIFICATION forming part of Letters Patent No. 561,945, dated J' une 9, 1896.

Application iilecl June 17, 1895. Serial No. 553,119. (No model.)

To all whom t may concern:

Be it known that I, JAMES MCGARRY, a citizen of the United States, residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Car-'Tentilators, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention consists in a ventilator for railway-trains, and especially in the construction of a ventilator-pipe extending from a funnel in front of the locomotive over or through the train, flexible couplings between the cars, valve-controlled openings from the pipe into the car, and exhaust-pipes leading 'from the bottom of the car through this pipe to the outside, and, further, in the construction and arrangement off the various parts, all as more fully hereinafter described.

In the drawings, Figure l is an elevation of my apparatus, showing in dotted lines the locomotive and one car of a raih yay-train. Fig. 2 is a vertical section through one of the exhaust-pipes. Fig. 3 is a longitudinal section villustrating the construction and arrangement of such pipe. Fig. 4 is a sectional perspective view illustrating the construction and location of the valves in the ventilatorpipe. Fig. 5 is a similar View illustrating the construction of deflector-nozzles intended to eitect the forcing of the air int-o the car or to draw the air out of the car by a current passing through the ventilator-tube. Fig. G is a longitudinal section through one of said deflect-ors, illustrating their construction. Fig. 7 is a cross-sectional view taken through the deilectors and showing the gate closing4 the aperture in the pipe.

A is a section of pipe on the locomotive, B on the tender, and C on the cars. These pipesections are detachably connected together at their ends by means of the inverted- U -shaped flexible couplin g-sections D. The forward end of the locomotive-section in front thereof is provided with an enlarged funnel D.

The pipe-section through the car passes beneath the roof and at the end of each car passes through the roof, as shown. lVithin the car, and preferably)7 upon the bottom, the pipe is provided with apertures E, controlled by sliding valves or gates F. Inside the pipe are the oppositely-inclined hood-shaped deflectors a b, preferably connected together and adapted to be moved around the inner face of the pipe, so that either one of these detlectors may be arranged over the aperture. To the dividing-partition of each of the delectors a b is secured an operating-handle e, extending through the aperture E. In the side wall of the aperture E and also in the adjacent track for the sliding gate F is a depression or notch d, into which the handle c is adapted to be pressed out of the path of the sliding gate F, when the latter can be slid in its track to close the aperture E. The air through the pipe passes in the direction of the arrow, as shown in Fig. 5. If the deiiector o is over the aperture, it will catch and deilect the air into the car, 'while if the deflector b is arranged over the aperture the air passing over the deilector will act somewhat on the principle of an injector and draw the air from the car into the pipe and out through the rear end thereof. Thus I am enabled to utilize the force of the passing current through the ventilator-pipe, either to force air into the ear or to draw air therefrom.

As it is desirable to take out the im pure air near the door, I arrange the exit-pipes G at suitable points in the car, having open lower ends and extending to the top of the car and into the ventilator-pipes, passing out through that pipe at the end of the ear and terminating in a nozzle or open end Il just outside the end of the car. One of these pipes extends to each end. These pipes may be provided with suitable danipers I. Then the car is in motion, if the forward pipe G is open air is forced therein by the motion of the train and will discharge in the car near the door, while the air will be taken from the iloor through the rear pipe and discharged at the rear end thereof. Thus, no matter which way the car is going, my construction provides a proper ventilation for taking air in. at the iloor and at the roof and for drawing the air out of the car at both points.

What I claim as my invention isl. The combination with a railway-car, of a ventilator-pipe passing therethrough near the roof having apertures therein, and deiiectors each having a sliding engagement with the pipe and provided with oppositely- IOO arranged hoods adapted to separately register and control said apertures, and Valves F for 1o with and control the said apertures, substansaid apertures, substantially as described. tially as described. In testimony whereof I affix my si gnature 2. The combination with a railway-ear, of in presence of tWo Witnesses. 5 a ventilator-pipe passing therethrough near the roof having apertures therein, deflect-ors JAMES MCGARRY. each having a sliding engagement with the Vtnesses: pipe and provided with oppostely-arranged T.
