UNITED STATES CONRAD PQEHNER, OF CINCINNATI, OHIO.

VENTILATING wrnnow.

Application filed February 14, 1922. Serial No. 536,511.

To all whom it may concern:

Be it known that I, CONRAD POEHNER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Ventilating Windows, of which the following is a specification.

This invention relates to improvements in ventilating windows of street and railway cars, and has for its object the provision of a novel mounting for such ventilating windows together with peculiar means whereby all of the windows may be adjusted in an entirely open, closed or a partly open position by a single movement of a control lever mounted at one end of the car.

An important object is the provision of a novel connection of the operating means with the individual windows whereby they may be opened and closed easily and without binding.

Another object is the provision of a novel device located at one end of a car for normally tending to close the windows, this structure embodying spring means applying tension to the connecting means of all the windows.

A further object is the provision of a lever device located at the other end of the car whereby all the windows may be moved simultaneously and be locked in a certain desired position.

An additional object is the provision of a structure of this character which will be comparatively simple and inexpensive in manufacture and installation, positive in action, easy to operate, highly efficient and durable in service, and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which:

Figure 1 is a somewhat diagrammatic longitudinal sectional view through a railroad coach or car showing my mechanism associated therewith; j

Figure 2 is a fragmentary longitudinal section through acoach looking at a plurality of the ventilating windows;

Figure 3 is a horizontal sectional view on the line 33 of Figure 2 showing the windows closed;

Figure 4 is a similar view showing the windows open;

Figure 5 is an elevation of the spring mechanism mounted at one end of the car, normally tending to hold the windows closed;

Figure 6 is a longitudinal sectional view therethrough; V

Figure 7 is an enlarged view of the levelmechanism at the other end of the car;

Figure 8' is a detail view of the locking means associated with this control lever.

Referring more particularly to the drawings, the letter A designates a portion of a railroad coach and B and C designate the ends thereof. In carrying out my invention I provide a plurality of ventilating windows 10 which are arranged in series at a point not far below the car roof and each of these windows includes an elongated preferably glass cover or frame 11, hinged at 12. Secured upon each frame 11 is a bracket 13 having its intermediate portion offset away from the frame, as shown at 14. Secured upon the side of the car below the window openings are L-shaped brackets 15, there being'one for each window. Each of these brackets includes a plate like attaching portion 16 and a reduced horizontally extending portion 17 which carries an upstanding threaded pin 18 surrounded'by a ball race 19 within which are disposed bearing balls 20. Pivotally engaged upon each bracket '15 is a curved arm 21 which is of compound curved shape, as shown, and

-which has its intermediate portion formed with a hole revolubly engaged upon the pin 18 and held against dis-association therefrom by means of a suitable nut 22. The end of each arm toward the window is forked, as shown at 23, and journaled in this fork is a roller 2a. The arm 21 is associated with the window by having the fork 23 straddlingthe offset portion 1 1 of the bracket 13 with the roller 24: engaging against this offset portion between the same and the window frame, so that there will always be a positive connection between the arm 21 and the window. The other end of each arm is forked, as indicated at 25, and pivoted between the forks 25 of all of the arms at each side of the car is a rod 26 which is adapted to be moved by the mechanism to be hereinafter described for the purpose of simultaneously moving all of the windows 11.

' in cut.

Mounted upon the end B of the car is an upright cylinder 27 which is hollow and which is provided with attaching plate portions 28 through which pass suitable securing members which hold the cylinder upon the car. The upper end of the cylinder is extended. to define a pair of ears 29 between which is journaled, as shown at 30, a grooved pulley 31 about which is trained a flexible band or cable 32 which has one end disposed within the fork of the nearest arm 21 and pivotally connected therewith by the same pivot pin 33 which connects this forked end of the arm with the rod 26. The other end of the flexible-band or cable 32- extends down into the cylinder 27 and is connected with one end of a normally contracted coil spring 34 which has its other end secured to the bottom of the cylinder. The function of this spring 34 is to tend to close the windows by exerting tension upon the longitudinal rod 26.

Mounted upon the'other end C of the car is a lever 35 which has one end engaged upon a pivot pin 36 extending from an attaching plate 37 secured to the coach and which has its other end provided with a handle 38. This lever is movable within a guide bracket 39 which limits the degree of move- Immediately above this guide bracket is a hole 40 through the end of the coach and adjacent which .is pivoted a grooved pulley 41 about'which is trained a flexible band 42 which has one end secured to th lever and which has its other end pivoted within the fork 25 in the other endmost arm 21 of the series. The lever 35 carries a spring pressed manually releasable pawl 43 which operates with a ratchet bar l-tsecured upon the end of the coach whereby to hold the lever 35 in adjusted position.

Assuming that the device has'been constructed, assembled and installed as above described and as illustrated in the drawings, it will be seen that when all the windows are closed the coil spring 34 will be in fully retracted position within the cylinder 27 and that the lever 35 will be in horizontal position engaging the upper end of the guide bracket 39. In order to openthe windows the operator grasps the lever handle 38 and swings the lever downwardly upon its pivot 36 whereupon a pull will be exerted upon -the flexible band 42 which will cause the rod 26 to be moved longitudinally, swinging all of the arms 21 upon their pivots 18. As the arms thus swing it will be apparent that owing to their engagement with the offset brackets 13 the windows 11 will be swung into more or less open position, depending upon the extent of movement of the lever 35. Owing to the provision of the rollers 24 there will be no binding, as these rollers will roll along the inner faces of the offset brackets 13, that is the faces toward the windows. As the rod 26 is moved longitudinally the spring 34 becomes distended and consequently exerts a. pressure tending to return the rod 26 to normally window closing position. The lever 35 is held in adjusted position by means of the pawl and rack mechanism described and shown so that the windows may be locked in partly or entirely open position when desired.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a simply constructed and easily installed system of ventilating windows in which the construction is such that all the windows may be opened or closed simultaneously from one end of the car, thus avoiding the necessity of closing the individual windows when approaching tunnels or for any other reason. Itis tobenoted that the various nuts, arms and brackets may be formed in a more Or less ornamental manner so that the entire mechanism will present a pleasing and attractive appearance. Owing to the simplicity of the construction and the fewness of the parts it willbe'apparent' that there is nothing to get out of order and that the device should consequently have a long life and satisfactorily perform all the functions for which it is intended.

While I have shown and described the preferred embodiment of the invention, it is of course to be readily understood that I reserve the right to make such changes in the form. construction and arrangement of parts as will not depart from the spiritof th invention or the scope of the subjoined claim.

Having thus described my invention, I claim! In a ventilating apparatus, a window frame having a plurality of openings, sashes hinged at one end of the openings for covering the same, brackets secured upon the sashes and each being of substantially U-shape including a major portion offset outwardly away from th sash and terminating in attaching feet secured thereto, other brackets securedupon the window frame'at each opening, compound curved arms pivoted on'said second named brackets and having offset ends carrying rollers engaged with the offset portions of said brackets between the same and the sashes, a rod pivotally connected with all of the arms, and means for moving said rod longitudinally.

In testimony whereof I afiix my signature. I

CONRAD POEHNER.
