SPARK AND WEATHER STRIP.
Application filed January 21, 1928. Serial No. 248,549.
This invention relates to railway cars, and particularly to the spark strips and weather strips which are carried by the doors and jambs of the door frames for the purpose 5 of preventing the entrance of rain or snow into the interior of the car and preventing the entrance of sparks.
In the patents granted to David R. Conrad, Nos. 1,569,799 of January 12, 1926, and 1,635,- lU 926 of July 12, 1927, there is shown a car door which, when the door is open or to be opened, is supported by a vertically movable rail which lifts the door off toothed seats and permits the door to move outward away from the front of the car andy to be slid freely toward or from ay closed position. Disposed above and below the door `are downwardly and inwardly inclined racks and thel door at its top and bottom is also provided with downwardly and inwardly inclined racks so that when the door is lowered the door will shift automatically toward the car and into closed position and be locked by the engagement of the racks on the door with the racks on the door frame, and when the door is raised and freed from its engagement with the racks on the door frame, the door will move outward.
The general object of the present'invention is to provide a spark land weather strip construction for a door of this character which will properly strip the door when the door is fully lowered and forced toward the side of the car or when the door is raised but not shifted to its open position, and to this end to provide a weather strip preferably mounted upon the door itself having two spaced flanges and provide a weather strip upon the side of the car or u on the door frame with which either of said anges will engage to close any 'possible opening between, the door and the side of the car so long as the door is closed and will also close any opening when the door is raised but not shifted to ,an open position.
Our invention is illustrated in the accompanying drawing, wherein Figure 1 is a fragmentary horizontal section through a. car and door showing our improved spark and weather-strips applied thereto, the door being locked;
Figure 2 is a like view to Figure 1 but showing the position of the door when the door is moved upward and outward;
Figure 3-is a fragmentary vertical sectional View through the car at thedoor opening and lthrough the door showing the door in-its l0wered position lwhich projects outward from the Figure 4. is a fragmentary sectional view on the same plane as Figure 3 through the upper portion of the door and adjacent portions of the door frame showing the door moved upward.
Referring to this drawing, A .designates a car having a door opening B defined b the vertical beams C constituting the jam s of the door and projecting out beyond the car wall. Designed to close the opening B is the door D which is illustrated as an all'metal door formed of one or more sheets of metal 10 having the vertically extending'ribs 11 formed thereon and shown as reinforced by channel irons 12 disposed within the ribs and riveted thereto at 13. The manner in which this door is mounted is clearly shown in the patents heretofore referred to but, as shown in Figure 3, the lower margin of the door is provided with the' wheels 14 adapted to engage a rail 15. This rail is longitudinally movable and is provided with cam slots whereby, as the rail is shifted in one direction, it will be raised and as the rail is shifted in the other direction, it will be lowered.
The door at its upper marginis provided with outwardly projecting plates 16 which are provided with rack teeth. Coacting with this outwardly projecting plate is a downwardly and inwardly projecting bracket or plate 17 having teeth coacting with the teeth on the angle rack 16. The lower margin of the door is also provided with an angularly however, the rail 15 is lowered, the rack teeth 18 will sli-de against the teeth on the brackets 19 and the teeth on t-he angular plate 16 will slide against the teeth on the brackets 17 and the door will move inward. Y
As before stated, it is the purpose of this invention to provide means for weatherstripping the ldoor either in its inward or outward position, and to this end we mount upon one vof the door j ambs the anule iron 2() face of the jamb, as shown at the left hand end of- Figure 1. Mounted upon the lateral margin of the projecting portion of the other jamb is an angle iron 21. j The door at one margin carries the channel-shaped weather-strip 22 having an inner flange 23 coming to the edge the flange 28, in either case preventing the' of the metallic door and extending outwardly and laterally land then being formed with the outer flange 24. These two flanges 23 and 24 coact with the flange 25 of the angle iron 20 so that when the door is forced outward the flange 23 will come in contact with the flange 25 and, when the door is forced inward and downward, the flange 24 will come in .contact with the flange 25, thus under either circumstance weather-stripping the door and preventing the entrance of sparks.
The opposite margin of the door has attached to it the channel iron weather-strip 26 having an inner flange 27, this flange 27 extending toward the center of the door and ,engaging the flange 28 of the angle iron 21.
When the door is in its lowered position and is forced against the car wall or the jambs of the door, the flange 28 will bear against the inside surface of the door 10 and, when the door is forced upward and outward, the flange 27 will bear against the inside face of entrance of rain or snow into the interior of the ear and Y preventing the entrance of sparks.
The bracket 17 also supports an angular strip 29 having a depending flange and the strip which constitutes the rack bar 16 has an upwardly extending'flange 30. When the door israised and forced outward, this flange 30 will' contact with the strip 29. When the door is lowered and forced inward, the rack teeth on the angle bar 16 will engage the rack teeth on the member 17 and thus the top of the door will be fully protected against the entrance of rain, wind or snow. t
It will be seen that the plate 17 constitutes a water lshed extending out over the door and preventing any possible leakage of Water into the space between the top of the door and the top of the door frame. The plate -17 is preferably of sheet Ametal with t-he rack teeth stamped out therefrom and the same is truev 4of the plate 16. Of course, when the door struction which shows this weather-strippingv as applied to a metal car door vconstructed in a particular manner, we do not wish to be limited thereto as it is obvious that changes might be made in thesepdetails without departing from the spirit of the invention, and that the same principle of weather-stripping might be apphed to Wooden car doors or to -metal doors constructed differently from the doors illustrated.
We claim 1. In a car having a door opening having jambs, a ydoor movable longitudinally and movable inward toward the car or outward away from the car, weather-strips on the end margins of the door, cach channel-shaped in cross sect-ion to provide two spaced flanges extending parallel to the door, and strips on the door ambs having flanges projecting 1nto the spaces between the flanges of the door strips and engaging with the outer or inner flanges of the door strips when the dooris forced fully inward or fully outward.
2. In a car having a door opening defined by door jambs, a door movable longitudinally and movable inward toward the car or outward away from the car, two weather-strips at the end margins of the door opening, each angular in cross section vand attached to the door jambsand projecting in the same direction and parallel to the wall of the car, the door having on its end margins two channelshaped strips between which the flanges of said first named weather-strips project when the door is closed, the weather-strips on the car and on the door coacting to close the space between the door and the car either when the door is pulled fully outward or pushed fully inward. Y
3. In a car having a door opening defined by jambs, a door movable longitudinally and movable inward toward the car or outward away from the car, the door jambs having weather-stripping members attached thereto providing flanges extending parallel to the wall of the car and substantially the full height of the door opening and spaced from the faces of the ambs and' both extending in the same direction, the door being formed at its end margins to provide outer and inner spaced members between which the flanges are received when thedoor is closed, said flanges contacting-with the outer members when the door is pulled outward and with the inner members when the door is pushed fully inward.
