SPECIFICATION forming part of Letters Patent No. 423,835, dated March 18, 1890.

Application filed December 2, 1889. Serial No. 332,201. (No model.)

To all whom t may concern:

Be it known that I, OLIVER II. TAYLOR, of Brooklymin the county of Kings and State of New York, have invented a certain new and useful Improvement in Oar-Ventilatore, of

which the following is a specification.

My improvement relates to car-ventilators which are arranged near the top of the car, and in carrying out my improvement I operate all the ventilators upon one side simultaneously, and I may swing them in different directions, and when so swung may lock them all in a iiXed position.

I will describe in detail a car-ventilator embodying my improvement, and then point out the novel features in the claims.

Figure l is an elevation, partly in section and partly broken away, showing a car-ventilator embodying` my improvement. Fig. 2 is a horizontal section taken on the line c, Fig. l. Fig. 3 is a vertical section taken on the line y y, Fig. l. Fig. el is a detail showing a portion of a single ventilator and the frame in which said ventilator swings. Fig. 5 is a detail View of' a certain portion of the car-frame hereinafter to be described. Figs. L and 5 are drawn to a larger scale than Figs. l, 2, and 3.

Similar letters of reference designate corresponding parts in all the figures.

Railway-cars of the passenger type are provided as a rule with an upwardly-extending portion, which portion rises from the roof of the car.

In the accompanying drawings, A represents such upwardly-extending portion. A ventilator or ventilators B is or are arranged at the sides of said upwardly-extending p0rtion A in suitable sashes or frames'. I have only illustrated one of such ventilators; but it is to be understood that any desired number may be employed; and I further wish it understood that all such ventilators may be operated simultaneously and to any desired extent in either direction.

I have shown a very convenient means for operating a ventilator or a number of ventilators, consisting in a longitudinally-movable rod O. The rod C has connected to it a gearsegmenti) in this example of my improvement, which segment gears with a pinion E.

The pinionE is rigidly keyed upon the lower pivot a of the Ventilator B. Consequently when longitudinal movement isiinparted to the rod O the pinion E will be rotated to cause the swinging of the ventilator B in either direction-that is to say, that it may be swung into the central position shown in dotted lines in Fig. 2, or it may be swung into the position shown in full lines in said figure, or it may be swung into a position the reverse of that shown in full lines in Fig. 2, or it may be swung into any position intermediate of the positions referred to. The result of this is that the ventilator or ventilators may be swung into any position desired, according to the direction in which the car is moving or the wind may be blowing.

In order that the ventilators may be wholly closed when swung in either of two directions, so that they will be substantially in alignment with their frames or sashes and in line with each other, I have shown each side edge of the ventilator as provided with a metallic strip h, and the portion of the frame adjacent-to the edges of the ventilator as provided with metallic strips h. I prefer that these strips should be faced with india-rubber, leather, or any other suitable substances which will operate to deadenthe noise which might be produced by the closing of the ventilator. In Fig. 4 I have shown the strips as provided with such a covering. It will be seen that by using the strips b h the ventilator can be tightly closed if necessary, so as to exclude air in whichever direction it may be swung.

I have shown a means for operating the rod O, consisting of a lever F, which lever is fulcrumed upon the frame of the car, as shown at. e. A link f is connected both with the'lever F and the rod C. Collars g, arranged upon the rod O and upon the opposite sides of the portion of the link f which connects with the rod O, operate to prevent the movement of the link without a corresponding movement of the rod O. A

It will be seen that in the present example of my improvement where a gear-segment is employed to rotate the pinion E there will not only be imparted to the rod O a longi- IOO tudinal movement, but there will also be a l slight lateral movement of said rod bodily. In order to compensate for this, the bearings h, through which the rod C passes, are provided with horizontally-extending slots fi. (Shown more clearly in Fig. 2.) These slots admit ot lateral bodily movement of the rod C. It is to be observed, further, that the rod C does not yield, but on the contrary is rigid. \Vhen, therefore, the rod @,byits longitudinal movement, imparts rocking movement to the ven tilator or ventilators in either direction, it will, when locked against further movement in any given position, maintain the ventilator or ventilators rigidly in the position into which it or they have been moved. Asa convenient means for securing the ventilator or ventilators rigidly in any position into which they may have been adjusted, I provide the lever F with a tooth (Shown more clearly in dotted lines in Fig. l.) This tooth I close to engage a rack j2. It will be quite clear that by this means the ventilator or ventilators may be held rigidly in any position into which they may be adj usted.

I wish particularly to call attention to the fact that by the movements of the rod C the ventilator or ventilators can be shifted into any desired position to cause a suction of the air from the interior of the car irrespective of the direction in which the car is going, and that in any desired position into which the ventilator or ventilators may be shifted it or they may be rigidly locked.

Attached to the ear-frame A, beneath the lower end of the ventilator, is a plate (Z, against which the lower pivot a, to which is also attachedthe pinion, rests. The side bearings, however, are formed on the one side by the car-frame and 011 the other by a removable portion d', preferably of hard wood, and shown more clearly in Fig. 5. The gear-segment D is also pivoted to said plate d. The upper pivot a has a bearing in like manner against a plate (Z2, the removable portion be ing at d3. By this construction it will be seen that by slackening the screws d" in both upper and lower bearings and removing' the portions d d3 the ventilator and pinion can be taken completely out when it becomes necessary to do so-snch, for instance, as to take up slack caused by wear, dac. The wooden bearin will tend to prevent rattling or noise, such as mighthappen in the case ot inet-al bearings.

Vhat I claim as my invention, and desire to secure by Letters Patent, is"

l. The combination, with a centrally-pivoted ventilator, of a sash or trame in which said ventilator is pivoted, a longitudinallymovable rod having a connection with thc ventilator and operating when moved to swing said ventilator in cit-her of two directions, either to closing positions or to any desired position intermediate of said closing positions, said ventilator, when adjusted to either of its closing positions, being substantially in alignment with said frame or sash, substantially as specified.

2. The combination, with a centrally-pivoted ventilator, ot a sash or frame in which said ventilator is pivoted, a longitudinallymovable rod having a connection with the ventilator and operating when moved to swing said ventilator in either of two directions, either to closing positions or to any desired position intermediate ot' said closing positions, and a lock for rigidly securing said longitudinally-movable rod into any position into which it may be adj usted, said ventilator, when adjusted to either of its closed positions, being substantially in alignment with said trame or sash, substantially as specified.

The combination, with a swinging ventilator provided upon opposite edges with metallic strips, of a sash or frame, also provided with metallic strips with which the strips upon the ventilator will contact when the ventilator is closed in -either of two direc tions, and mechanism substantially such as described for moving said ventilator, sul stantially as specified.
