CA R D O O R SPECIFICATION forming' part 0f ALetters Patent N o. 564,157', dated July 14, 1896.

Application filed November 11, 1895. Serial No. 568,646. (No model.)

To @ZZ whom, it may concern:

Be it known that I, JOHN W. PARKER, a citizen of the United States of America, and a resident of Atlanta, in the county of Fulton and State of Georgia, have made a certain new and useful Car-Door; 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, reference being had to the accompanying drawings, and to figures of reference marked thereon, which forni a part of this specification.

This invention relates to the class of cardoors in which t-he door may either form a complete closure or may form a ventilated closure for the openings in the sides of the car, the object being to provide a superior form of construction for a door of this class, whereby its life may be increased and its usefulness improved, -the details of construction whereby these ends are attained being hereinafter fully set forth, and the parts for which protection is desired fully set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a portion of a car with this device in use as a ventilated door. Fig. 2 is a vertical cross-section on the line 2 2, Fig. 1, further showing the construction of parts. Fig. 3 is a perspective view of one of the hangers of the perforated or screen door, and Fig. 4 is a like View of one of the hangers of the outer or solid door. Fig. 5 is a sectional detail of the lock whereby the doors are held in their proper relative positions regarding each other and the opening in the side of the car.

In the gures like reference-marks indicate corresponding parts in all the views.

1 is the car, which may be of any class to which a door is applicable and which it is desired to lock.

2 is a bar) secured to each side of the car, above the correlative door-openings therein, and 3 is a track secured to the face thereof and usually consisting of a hat bar of metal screwed to said bar 2 in a suitable manner, with its upper edge projecting upwardly a suificient distance above the upper side of the said bar for the ends of the hangers to strike should there be any tendency of the door-hangers to jump from said track.

4. and 5 are bars secured to the sides of the car, on either side of the door-opening, and forming jambs or stops for the sliding doors in their movements.

The door 6, which is the perforated one, so made by the use of wire-cloth of standard mesh over the opening in said door, which should be as large as possible, is in thickness say one-half as thick as the bar 2, and is seated against the face of the car so as to move across and cover thedoor-opening when in proper position. Hangers 7 and 8 act to suspend same from the track 3, rollers 9 in the upper ends of said hangers serving to decrease the friction, and the ends 10 being extended downwardly a sufficient distance below the upper edge of said track and the pe ripheries of said rollers to engage said track in case the door should be accidentally removed from its proper position.

The hanger 7, as shown partly in broken lines in Fig. 1, is in the form of a strap having an offset at 11 leading said strap out from the face of the door G around theface of the track 3, whence it projects upwardly and is turned backwardly and downwardly, the roller 9 thereof being journaled between the sides so formed, and the end projecting below the upper edge of the track, as hereinbefore stated.

The upper stile of the door G is extended beyond the edge of said door and the strap of the hanger 8 has an eXtension12 lying along the projected portion of the stile and being provided with an upturned portion 13, which carries on its upper curved end a roller 9,

, and has an offset like the offset in the h. nger 7 at 11 for the same purpose.

The strap of the hanger or the portion secured to the door may be of any form, but the form shown is preferable, it being T- shaped, the vertical bar lying upon the side stile and the cross-bar lying upon the top stile and including the extension 12. The upright 13 of this hanger is thus projected beyond the edge of the door, as is also the same portion of one of the hangers vof the other door, for a purpose which will be hereinafter shown.

IOO

14. is the solid or imperforate door, and is seated outside of the door G, beingl suspended from the same track on hangers 15 and 1G. This door should be a little thicker than the door 6, and is seated with its upper edge partly (mostly) under the bar 2 and the track 3, the bevel 17 being formed thereon -for the purpose of a water-shed, as seen in Fig. l.

The hanger 1G is formed like the hanger 7 and the hanger 15 like the hanger S, both h aving an oliiset portion 18 at .the angle of the bevel 1.7, and the hanger 15 projects upwardly from the extended stile 19 of the door, like the upwardlyqiirejeeting portion of the hanger 8, each hanger being in like manner provided with rollers O.

2O are brackets inside of the upper end of which the lower edge of the door 6 moves, and 21 a-re brackets which serve to hold the door 14 in place when at its two limits of movement. These doors maybe locked in any of their positions by means of a device which I will now describe. A hole is cut in the door 1-1, a like hole being eut in each edge of the door 6 and being provided with escutcheons 23, set at the points in said door where they will register with the holes in the door 14 when the door 1i. is respectively over saiddoor G and ott of same, as seen in Fig. 1, like holes a-nd escntchcons 2t being cut and placed on the siding of the car under the escutcheons 23 when the door (l is in the position shown in Fig. 1. A lever 25 is pivoted on an element 2G, screwed to the door 1l, over the hole therein, and an arm 27, curved on a radius from the pivotal point of said lever 25, is secured to said lever in such a position that it will pass thron gh the said escutcheon and those marked 23 and 2t, thus locking the doors in any of their positions relatively to the doer-opening and to each other. For example, in Fig. 1 this arm 27 passes through the door 14, the escutcheon ...3 in the door (i, and into the escutcheon 21 in the siding of the ear, the two latter-named escutcheons being the left-hand ones in said gure. lVhen the door 6 is pulled from over the opening in the side of the car, the arm 7 passes through the same escutcheons, except that the escutcheon (right) is moved under the door lt and the arm passes through it. lVhen the door 1st is moved over the door 6, when said door 6 is in the position shown in Fig. l, the escutcheon 24 (right) is substituted for the escutcheon 24, (left,) as is also the case with the escutcheon therewith.

Thc lever 25 is tachcd, and thus the doors be sealed in any position or arrangement.

In this device it will be observed that the screen-door may be moved over the opening in the side of the car without the door 1-1 aceompanyin g it, as would be necessary in order to form a perforated closure, and, indeed, this is the only time at which the wire-cloth and the screen-door, 'both comparatively easily destroyed, are exposed tothe elements and to having bales and barrels strike them. lVhen the door is open, that is, the scrcendoor under the door 141, and both in the position in which the latter is shown in Fig. 1, Y

the door 6 is under the door 14; and protected, and it is also protected when the door 1 4 is over the opening, inasmuch as, owing to the engagement of the hangers 7 and 15 and 8 and 16, the said door 14: cannot be moved over the opening without carrying the door (5 with it. By reason of both doors being under the bar 2 it is obvious that so long as the lower edges of same are held nea-r the car the said doors may not be thrown from their places, and by reason of the same fact and the watern shed on the upper front edge of the door 1l no water may enter the crack, whereby the cargo if it be near the door will not be wet p duringrain-storms and the interior of the car will at all times be perfectly dry.

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

1. In a ear-door, a perforated door and an imperforate door mounted so as to move across the same, a track, and hangers, the hangers on one side of each door interlocking' with the adjacent hanger of the other door, tor the purpose specified.

2. In a door, two doors adapted to slide past each other their inner hangers interlocking, and their other .han gers being projected beyond the ad jacent vertical edge oi' its door for the purpose specified.

3. In a car-door, two doors adapted to move across each other, holes therein registern g in sets, and a correlativo hole in the side oil. the car, and a hasp pivoted to the outer door and carrying within the hole thereof a pin adapted to enter each set of holes and engage said doors.

In testimony whereof I hereunto al'iix my signature in presence of two witnesses.
