sTTas ALBEET S. MARGASON, OF SAN JOSE, CALIFORNIA.
WINDSHIEIiD FOR CLOSED^MOTOR CARS.
Application filed August 18, 1923. Serial No.V 658,154.
To all whom it may concern.'
Be it known that I, ALBERT S. MARGASON,
a citizen of the United States, and a resident of San Jose, in the( county of Santa Clara and State of California, have invented certain new and useful Improvements in Windshields for Closed Motor Cars, of
which the following is a specification.
In building closed motor cars it is customary to provide the doors with vertically sliding sashes whereby ventilation of the car may be effected. Butl these windows are so arranged that when tl'e sashes are dropped and the car is in motion, strong currents of air enter therethrough and not only cause great physical discomfort to the occupants of the car but not infrequently cause the Vdevelopment of more or less severe colds.
It is the object of this invention to provide means for deilecting the air currents in such aY manner as to prevent` undesirable edd-ies and currents of air in the car when the window sashes are open and the car is in motion.
It is another object of the invention to provide a means of the character indicated that will not interfere with the vision of the occupants of thecar.
It is still another object of the invention to provide a means of the character indicated that will be rigidly mounted upon the car door and consequently movable with the door and free from vibration independl ently of its support.
I attain these objects by means of the mechanism illustrated in the accompanying drawings, in which,-
Figure 1 is a side elevation of the device in position on a car door.
Figure 2 is a section on line 2-2 of Figure 1.
Figure 3 is a diagrammatical illustration showing the position of the device relative to the car body and thedoor window.
Referringy more particularly to the drawin I show at 1 the body of aclosed car, 2 a door therein, 3 the window opening in said door, and 4; the vertically movable sash in said window opening.
In applying my invention to a car door window, I provide two brackets as 5-5.`
Each bracket comprises a triangular portion 6 having a flange 7 turned at' right angles thereto along one edge of yone leg of the triangle, and provided with orifices whereby the same may be screwed to the door 2. That edge of the element which forms the hypothenuse of thel triangle is turned at right angles to the normal plane of the element as shown at 8 and provided with a groove 9, the parts 7 and 8 extending in opposite directions. l
A sheet of glass 10 is now set in the opposed grooves 9-9 of a pair of these brackets and secured therein in any suitable manner not shown. The two brackets and the glass shield being assembled it only remains to fasten it upon the frame of the car door as shown, that is with the brackets positioned in parallel relation to the top edge of the door and adjacent to the top and bottom edges of the window opening therein, and with the glass shield fitting snugly against the door frame adjacent to and parallel with the forward vertical edge of the window opening, the said glass then sloping lutwardly and backwardly from the car It is considered desirable to have the triangular parts 6-6 present an unbroken surface whereby air currents are prevented from sweeping around either the upper or the lower edge of the` device and so into the car.
The diagrammatical illustration in Figure 3 will clearly illustrate the results secured by the use of my improved shield upon a closed car when the same is in motion. With the window of the door open the air would ordinarily enter therethrough with greater or less force according to the speed of the car, these air currents edd ing freel and with some force about the eads of t e occupants of the car as indicated by arrows 1l. The only alternative to such a condition has heretofore been to close the sash in the' door. This is not usually desirable, of course, because the air in the tightly closed carsoon becomes foul.
By a plying the shield as described, how- 10o ever, t e air currents are deflected suiiiciently to pass by the open window and strike the car to the rear thereof. Since most closed car bodies taper somewhat toward the t .front the tendency of the air to enter an 105 open window is much greater than if the sides were parallel. It is desirable, therefore, to so proportion the shield that its outer vertical edge be substantially in alignment with the corresponding rear vertical edge of the car body in a plane parallel to a plane bisecting the body longitudinally and vertically.
Results are obtained by this arrangement that are even superior to results that might be obtained upon a car having parallel sides for the reason that the angular space 12 becomes a more orless dead airl, space, or a space filled with minor eddies' and consequently there is no excessive passage of air into the car nor any excessive passage of air out of the car. No matter how great the s eed of the car may be no undue circulatlon of air Within the car is apparent to occupants thereof.
This device is rigidly mounted upon` a car door in such a manner as to become essentially an integral part thereof. `The angular relation of the glass portion to the car body is fixed, and the angle is such as in no Way to interfere with the usual normal functioning ofthe door.
lt might be further mentioned that the device in defiecting the air currents also materially reduces the quantity of dust, in-
sects, etc., that ordinarily blows into a car,
when atmospheric conditions are such as to render the opening the door sash imperative.
it is to be understoodj of course, that while l have herein shown and described ,one specific embodiment or my invention, changes in form, construction and method of application may be made Within the scope of the appended claim.
l claim g- A. shield for car windows comprising a pair of bracht-,tsi each bracket comprising a triangular portion having a flange turned at right angies thereto along the edge of one leg of the triangle, and means fori securing the same to a door, that edge of the element forming the hypothenuse of the triangle being turned at right angles to the normal plane of the element and provided with a groove, and a transparent shield fixedly mounted in the opposing grooves of the two triangular elements.
