CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 689,737, dated December 24, 19 01.

Application filed April 4, 1901. Serial No. 54,311. (No model.)

To ctZZ whom it may concern.-

Be it known that LRIOHARD MoBLEY,a citizen of the United States, residing at Princeton, in the county of Gibson and State of Indiana,have invented new and useful Improvements in Gar-Doors, of which the following is a specification.

This invention relates to certain new and useful improvementsin car-doors, and more particularly to what may be termed a flush car-door adapted to fit snugly into the door able guideways to permit of sliding the door away from the door opening or casing and to also protect the top of .the door from rain, sleet, or snow, so that the same will not interfere with the operation of the door, as well as preventing sparks or other matters from entering the car; furthermore, to construct the bottom of the door with a series of ball races carrying ball-bearings to materially assist the operator when sliding the door to and from the door opening or casing.

The inyention further aims to construct a flush car-door and the operating means therefor which shall be extremely simple in its construction, strong, durable, and efiicient in its operation, and comparatively inexpensive to set up; and it consists of the novelcombination and arrangement of parts hereinafter more specifically described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail refe r- 'ence is had to the accompanying drawings,

forming apart of this specification, wherein like numerals of reference indicate corresponding parts throughout the several views, and in whichi Figure 1 is an elevation-of a portion of a side ofa car, showing my improved door attached thereto and the operating mechanism for the door. Fig. 2 is a sectional elevation showing the door in its open position. Fig. 3 is a like view showing the door closed. Fig. 4 is a perspective View of the operating mechanism for the door, and Fig. 5 is a detail showing the I Rotatably mounted within the bearing brackets 6, secured to the car at each side of the sill 4, is an operating-rod 7, which extends entirely across the sill 4 and has mounted thereon the lower elevating or shifting track 8. The track 8 is substantially concave in contour, is secured to the rod 7 by the screws 9, and is provided with the reinforcing-strips 10 upon the outer face thereof.

Extending across the side of the car as shown, is a series of supports 11, to which is secured the elongated guid e-rail 12 a suitable distance from the car. The guide-rail extends past the car-door opening the desired distance. The portion of the guide-rail which is not opposite the car-door opening has its inner face formed with an integral flange or offset, forming a stationary track 13. The portion of the inner face of the guide-rail arranged below the car-door opening is not provided with the flange or offset, so that the opl eration of the elevating or shifting track 8 will not be interfered with. The track 8 when in its lowered position is adapted to aline with the stationary track 13, forming therebya continuous track from end to end of the guide-rail 12.

Secured to each side of the top of the "cardoor opening is abearing-bracket 14:, in which are rotatably mounted the ends of the operat-i segmental-shaped guide-strip 18, alining with the shifting guide 16 when the latter is in its outer position, forming thereby a guide substantially the length of theguide-rail 12.

The shifting track 8 is concaved in the manner shown, so that the outer portion thereof will engage around the bottom of the door 19 and force the same within the cardoor opening snugly, as well as preventing the entrance of sparks, sleet, snow, rain, or other matters to the car. The shifting guide 16 is formed convexed, so thatthe outer portion thereof will engage around the top of the door 19 and force the same within the cardoor opening snugly, as well as preventing the entrance of sparks, sleet, snow, rain, or other matters to the car. The operation of the shifting track 8 and the shifting guide 16 is simultaneous, as will be hereinafter described. The guide-strip 18 is formed in a segmental manner to protect the top of the door from rain, sleet, or snow, the shifting guide 16 also protecting the top of the door 19 to that effect.

The door 19, which is adapted to operate upon the tracks Sand 13, is provided at each side with an outwardly-extending reinforcingstrip 20 20, respectively, which extends from top to bottom of the door. The strips 20 20 extend over and upon the side of the car at the edges of the car-door opening, so that when the door is flush they will prevent the entrance of sparks orother matters to the car. Secured in any desirable manner to the bottom edge of the door 19 is a series of ball-races 21, preferably four, each provided with a ball-bearing 22. The ball-races are so constructed that the bearing comes on the sides of the balls and that While each ball travels the length of its race the door will have traveled its width. The races must also be constructed so that the balls must not have any bearing inside of the races, with the exception as before mentioned, and that the balls must not engage the top or ends of the race. Toobtaiu the arrangement of the balls in the manner shown, the inner face of the sides of the races is formed in a curvilinear manner and each end of the races with an abutment. The strip 20 is cutaway, as at 23 24, the former to permit the stop 25 to engage the door and the latter to permit of the operation of the operating-lever, to be hereinafter described. The reference-numeral 26 denotes a stop for the door when moved away from the car-door opening. The referencenumeral 26 denotes a suitable grip for removing the door from between the guides and tracks, so that it can be repaired when desired.

Secured at one side of the car-door opening, near the lower end thereof, is a plate 27, carrying a stud 28, to which is pivoted the operating-lever 29, provided with an apertured handle 30. The plate 27 has an opening arranged at each side of the stud 28. Attached, as at 31, to the lever 29 is the upper end of the link 32, the lower end thereof being connected, as at 33, to the outwardly-extending apertured lug 34, carried by one end of the operating-rod 7. Attached, as at 35, to the lever 29 is the lower end of the elongated link 36, the upper end thereof being connected, as at 37, to the outwardly-extending aperturcd lug 38, carried by one end of the operating-bar 15.

The reference-numeral 39 denotes a sealing device for the car as well as a locking means for the lever 29, and it consists of a pair of brackets 40,havin gone end thereof apertured and a catch 41 pivotally connected to the opposite end. The catch 41 is provided with an opening 12 in its free end, which is adapted to register with the apertures in the brackets 40. The catch 41 secures the apertured end of the lever 29 to the brackets 10, and when in such position a suitable sealing means is secured through the opening 42 and the apertures in the end of the brackets 40.

The operation of fitting the door snugly within the car-door opening 2 is as follows: Assuming that the door 19 has moved between the shifting track 8 and shifting guide 16, the lever 29 being in its normal position somewhat elevated, the lever 29 is then lowered, partially rotating the rod 7 and bar 15, elevating and moving inwardly the track 8, lowering and moving inwardly the guide 16, and forcing the door 19 within the car-door open ing, the door fitting snugly within the opening. The operation of the rod 7 and bar 15 is caused by the lowering of the elongated link 36 and the elevation of the link 32, the former attached to the bar 15 and lever 29 and the latter attached to the rod 7 and lever 29. On a reverse movement of the lever 29 that is, elevating the same-a reverse movement will be given the links 32 36, as well as the shifting guide 16 and track 8, causing them to aline, respectively, with thesegmental guide-strip 18 and stationary track 13, so the door 19 can be moved away from the cardoor opening, if desired.

It is thought the many advantages of my improved car-door and the operating means therefor can be readily understood from the foregoing description, taken in connection with the accompanying drawings, and it will be noted that various minor changes may be made in the details of construction without departing from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
