EDWVARD D. PEPPERS, OF MOBILE, ALABAMA.

CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 706,449, dated August 5, 1902.

Application filed January 25, 1902. Serial No. 91,266. (No model.)

To all whom, it may concern:

Be it known that I, EDWARD D. PEPPERS, a citizen of the United States, residing at Mobile, in the county of Mobile and State of Alabama, have invented certain new and useful Improvements in Car-Doors; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

My inventionrelates to improvements in car-doors, and more especially to that class of car-doors to be employed upon railway fruitcars.

My invention possesses certain features of novelty that will hereinafter more fully appear, reference being had to the accompanying drawings, wherein Figure 1 represents an outside view of a car upon which my invention has beenapplied. Fig. 2 is a slightly-enlarged view of the doors from the inside, showing the locking mechanism. Fig. 3 represents a section on the line 3 3, Fig. 1, looking in the direction. of the arrow. Fig.4 is a sectional view,enlarged, of the locking mechanism of one of the doors; and Fig. 5 is a perspective View of the looking mechanism removed from the car.

a I) represent a pair of outside doorssupported upon hinges c, said doors havinglbeveled edges adapted to firmly close the dooropening of the car. These doors are hinged upon and swing upon the outside of the car.

In the framework d upon the inside of the car are slidingly mounted the upper and lower doors 6 and f, respectively. The up per door e is provided with the vertically-disposed bars 9, allowing a free circulation of air. The lower door f is also provided with vertically-disposed bars 9 and also with a screen it, covering these bars. These two upper and lower doors .6 and f are free to slide independently of each other and are each provided with a catch 'M, respectively. In the jamb of the door is located a vertically-disposed sliding barj, provided with upper and lower openings 70, through which pass the catches 11 i, respectively, of the upper and lower doorseand f. Upon the lower end of this sliding bar j is provided a pin Z,

provided with a downwardly-projecting stop Z. This slidingbarj is mounted in the metal frame or casing m, which iucloses the same upon two sides, a stop m being provided upon the bottom of this frame or casing, upon which rests the lower end of the barj. Upper and lower openings n 0, respectively, are provided in this frame m, through which pass the latches i 1;, respectively, upon the upper and lower doors cf, respectively. This frame m and bar j are entirely inclosed in the doorframe and are entirely concealed and protected from View either upon the inside or the outside of the car.

19 is a rock-shaft passing through from the inside to the outside of the car, said shaft carrying upon its outer end the folding hasp q, adapted to be locked or sealed upon either of the eyebolts r 1" upon the outside of the car.

The inner end of the rock-shaft 19 carries a crank 8, provided with an arm 25, adapted to engage the pinZ of the sliding barj.

The operation of the doors is as follows: In the position shown in Fig.1 both doors e'and f are locked, the hasp q being upon the upper eyebolt r and the seal. passed there'through. The outer doors a 12 maybe left open or closed, dependent upon the cargoor the atmospheric conditions. To unlock thedoors, the seal is broken and the hasp qis removed from the upper eyebolt/r and placed upon the lower one 1'. The parts will then assume the positions shown in Fig. 2, the-arm t raising the pin Z, and consequently the sliding bar j. which releases the spear-headed latches't' t upon'the upper and'lower doors, respectively. Both doors may now be opened, or, if desired, only one door may be opened, the remaining door being left closed and again locked.

The doors will be automatically locked when closed'while y the sliding bar j is in its lower position, either singly or both simultaneously, it being impossible to again open either door until the hasp q is removed from the eyebolt r and swung into the position indicated by dotted lines in Fig. 1.

It will thus be seen that a Ventilating cardoor is provided, and while free circulation of air is provided through this door, yet perfect securityis attained, it being absolutelyimpossible to open either door without breaking ICO the lock or breaking the sealcircumstances which would at once indicate that the contents of the car had been tampered with.

While I have shown my invention as embodied in the particular form shown and described, it will be understood that I do not limit myself. to the precise details of construction, as many changes and modifications might suggest themselves to any one skilled in the art.

Having thus described my invention, What I claim, and desire to secure by Letters Patent of the United States, is

1-. In a car-door, the combination with a pair of upper and lower sliding doors, and latches carried by each of said doors; of a bar mounted to slide vertically in the doorframe, a stop upon the lower end of said bar, means carried by said bar for engaging said latches, a rook-shaft passing through the side of the car, a crank upon the inner end of said shaft provided with means for engaging said .stop upon said bar, a hasp upon the outer end of said shaft to operate the same, and eye- 1 bolts upon the outside adapted to secure said hasp in its locked and unlocked positions.

2. In a car-door, the combination with a pair of upper and lower sliding doors, and latches carried by each of said doors; of a bar mounted to slide vertically in the doorframe, a stop upon the lower end of said bar,

means carried by said bar for engaging said latches, a rock-shaft passing through the side of the car, a crank upon the inner end of said shaft provided with means for engaging said
