CAB-VENTILATOB.

Specification of Letters Patent.

Patented June 28, 1910.

Application filed August 24, 1909. Serial No. 514,404.

To all whom it may concern:

Be it known that I, FREDERICK W. SIM- SON, a citizen of the United States of America, and a resident of Winthrop, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Car-Ventilators, of which the following is a specification.

This invention relates to car ventilators and has for its object the provision of a ventilator which may be permanently installed in the framework thereof intermediate the windows and which may be readily regulated by any passenger adjacent to the ventilator.

The invention consists in two tubular members which are adapted to telescope into each other and be fixedly secured in adjusted position, the inner member being provided with a screen extending transversely of the bore thereof to prevent cinders from coming into the interior of the car while between this screen and the outer end of the ventilator is a pivoted damper which may be operated by a suitable mechanism extending into the car interior.

The invention consists further in certain novel features of construction and arrangement of parts which will be readily understood by reference to the description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents a vertical section through a ventilator, embodying the features of this invention. Fig. 2 represents a horizontal section of the same, the cutting plane being on line 22 on Fig. 1. Fig. 3 represents a transverse section of the tubular members, the cutting plane being on line 3-3 on Fig. 2, looking in the direction of the arrow, and Fig. 4 represents a transverse section of the same, the cutting plane being on line 44 on Fig. 2, looking in the direction of the arrow.

Similar characters designate like parts throughout the several figures of the drawin s.

Tn the drawings, 10 and 11 represent, respectively, the outer and inner portions of the car frame interposed between two car windows. These members 10 and 11 have openings cut therethrough in axial alinement in which are positioned the flaring ends 1213 of the outer and inner tubular members 14 and 15. The cylindrical portion of the tubular member 15 is adapted to enter the bore of the cylindrical portion of the tubular member 14 and when properly adjusted therein with the beads 16 and 17 formed upon the outer edges of the flaring conical ends 12 and 13 registering against the outer walls of the members 10 and 11. These members are secured in position so that they cannot turn by means of securing devices such as screws 18.

Fixedly secured in the cylindrical portion of the tubular member 15 is a screen 19 between which and the outer end of said cylindrical portion of the tubular member 15 is a pivoted damper 20, the pivot member 21 of which extends downwardly through a hub formed upon or secured to the cylindrical portion of the tubular member 15. The lower end of this ivot member 21 has secured thereto a mem er 23 which is connected by a link 24 to another arm 25 pivoted to a stud 26 formed upon or secured to the member 15.

Radiating from the stud 26 and formed integral with the arm 25 is an operating handle 27, the inner knobbed end of which extends into the interior of the car through an opening 29 formed in the flaring end 13 of the tubular member 15. It is obvious from an inspection of the drawings that a movement of the handle 27 from one end of the slot 29 to the other will close or open the damper 20, as desired, while an intermediate position between the two ends will permit a partial closing of said damper.

Extending diametrically across the flaring conical end 12 of the tubular member 14 is a deflector plate 30 normally vertical when in operative posit-ion, this deflector plate preferably extending beyond the outer face of the exterior wall 10 of the car frame. When the car is moving in the direction of the arrow as the deflector plate 30 will cause the air striking against the front face thereof to be deflected in the direction of the arrows b into the interior of the car when the damper 20 is opened, as indicated in Fig. 2 of the drawing.

Any cinders which may be deflected into theventilator will be prevented from passing into the interior of the car by means of the screen 19. When the damper 20 is in open position, as indicated in the drawings, the edge thereof substantially registers with the inner edge of the deflector plate 30, as indicated in Fig. 1 of the drawings.

Interposed between the screen 19 and the edge of the damper 20, when in open position, is a radial member 31 normally vertical and extending upwardly from the inner wall of the member 15, this radial member 31, damper 20, and deflector 30 all being in alinement when the damper 20 is in open position. This radial member 31 is provided on either side with flaring wings 32 which are adapted to deflect the heavier cinders which may enter the bore of the ventilator and cause them to be carried upwardly around the damper 20 and out upon the opposite side of the deflector plate 30. The inner end of the radial member or partition 31 is slightly removed from the screen 19 to permit any of the cylinders to pass around this end of the partition.

Just inside of the screen 19, the member 15 has mounted a revoluble ring 33 provided with a diametral member 3a to which is hinged in any well-known manner a deflector plate 35. The hinge between this plate 35 and the diametral member 3 1 has sufficient friction to cause the deflector plate 35 to retain any angular position relative to the revoluble ring 33 in which it may be placed by the passenger. It is obvious therefore that by the manipulation of this deflector plate 35 about its hinge connection with the ring 33 and by means of the rotation of the ring with the tubular member 15 the air passing through the ventilator may be deflected at the will of the passenger adjacent thereto. This provides a permanent fixture which is always in position for the passenger to operate as he may desire to secure the ventilation which he himself desires without disturbing others adjacent to him, and it also provides a means whereby the air thus admitted may be deflected as he may wish. It dispenses with the necessity of calling the porters to provide the usual ventilators which are adjusted in the window frame.

It is believed that the many advantages of this invention and its operation will be fully apparent without any further descriptlon.
