To all whom it may concern r Be it known that I, Josnrrr C. GOODMAN,

a citizen of the United States of America,

in the ventilator to be now described with respect to the accoinpanyingjdrawing, which forms a which, i

Figure 1 is a front elevation,

Fig. 2 is a horizontal section therethrough,

Fig. 3 is a rear elevation,

Fig. l is a vertical cross sectiontaken on line 4. l of Fig. 2, I

Figs. 5 and 6 are horizontal sections showing the rear adjustable closure in different positions,

Figs. 7 and 8 are respectively a partial front elevation and a vertical section through a slightly modified form,

Fig. 9 is a front elevation-showing an extended form of the unit construction Fig. 1, and

Fig. 10 is a diagramillustrating the application of the ventilator to a car.

Referring now to these figures and particularly to Figs. 1 to 6 inclusive my invention proposes a ventilator which includes a rectangular casing 10 having top, bottom and side walls, which is open at its rear and is provided at its front with a wall 11 extending only partly thereacross from one of the side walls 12.. Adjacent to the front is an air controlling member consisting of a plate 13 having a reverting flange 1e and a rounded portion 15 connecting the plate and flange and forming in the angle between the same a pocket. The plate 13 is mounted between the top and base of the casing 10 with its rounded portion 15 adjacent to one side wall 12 and with its free edge and the free edge of its flange 14 overlapping the free edge of the partial front wall 11' and dis-' posed in spaced relation thereto and respec tively within and beyond the same.

rounded portion 15 partially extends beyond the front ofthe casing so that'cinders, dust and the like checked by virtue of the tortuous path it is thus necessary for the air to take through the ventilator, may drop be low the same.

At its rear portion the top and base of the casing. have longitudinalguideways 16 in which an adjustable closure is slidably mounted, this closure consistingof plates 17 and 18 havinghandles 19 and thus shift able to ether toward either end of the casin for controlling the passage of air in the open position lSWlll be seen by acoinpar son Of'Figs. 2 and 5, as well as independently shiftabletoward the relatively opposite ends of the casing to the closed position as seen in F 1g. 6, it being obvious that the air iscaused to "traverse a more tortuous path with the with the parts in the position of Fig.2.

In either instance air passing inwardly between the flange 14: and the partial front like andinthis way separate the same from the air stream. J i

The construction as" thus outlined constiseries' of three controlling members at 20 operatively included to control the passage of air through separate compartments of a casing 21, in each of the compartments of which the respective member is disposed in relation to the other parts as described in connection with Figs. 1 to 6 inclusive.

In Figs. 7 and 8 I have shown horizontally extending air controlling members 22 in a casing 23, located to control the passage of air through a series of compartments at the rear portions of each of which is a vertically movable sliding closure 24 of the construction previously described In Fig. 10 I have shown diagrammatically the useof my invention in reversed relation at relatively opposite ends of a car 25, the ventilators at each end being turned so as to tutes unit and various numbersofthese units may be employed depending upon the In Fig. 9 Ihave shown a take in air at the front end of the car with respect to its direction of movement, when proceeding in either d1rect1on,the oppositely turned rear ventllator operating to exhaust air from the car under the influence of currents of air proceeding along the car side. In this way it is obvious that when moving in either direction the ventilator permits air to be taken in the front of the car andex- V hausted by a vacuum at the rear of the car.

With either of the forms of the invention shown and described ity is furthermore ob.-

vious air will be taken into the car at its front and expelled therefrom at its rear so that effective and efficient ventilation issecured. As shown in the diagram the form of'theimultiple ventilator of .9 be

utilized but it is equally obvious that the ventilator of Figs. 1 to 6 inclusive may used or a greater degree ofv multiplication resorted to, depending upon conditions of 7 use a'nd the requirements.
