A further object of this invention .residesin the provision of a freight-car dooi` consisting of a adapted to be locked against removal upon locking a certain section thereof.
A still further object of this invention resides in the provision of a freight-car door consisting of companion sections adapted to be movably connected to the body of the freight-car so as to prevent loss thereof 4when removed from their closed position. f
Aside from the aforesaid objects, this invention resides in a freight-car door consisting of a plurality of companion sections adapted to be retained in closed relation by certain interlocking means.
Among the many objects of this invention is the provision of particularly constructed locking With these and other objects in view this invention resides in certain novel features of construction and arrangement of elements to be hereinafter more fully set forth in the specification, illustrated in the accompanying drawings and pointed out in the appended claim and,v while this disclosure depicts my present conception of the invention, the right is reserved to resort to such changes inr construction Aand arrangement of parts as come within lthe scope of the appended claim. 1
In the accompanying drawings forming a part of this application Fig. l is a side View of a portion of a freightcar showing the door in closed position, thereon. Fig. 2 is -a cross sectional view thereof approximately `on line 2--2 of Fig. 1.
Fig. 3A is a longitudinal sectional view thereof approximately on line 3-3 of Fig. 2.

(o1. 2li-s0) online 6-' of Fig. 4 showing one of the boltreceiving lugs.
Fig. '.7 is a detail perspective view of a portion of one of the guide-rails.
In the present illustration of this invention, the letter A designates a portion of the conventional boX type freight vcar which among other adjacents thereof is provided with a doorway B havinga door 5. suitably secured to each opposite vertical edge of the doorway is a guiderail which preferably consists of a piece of nietalhaving a portion thereof offset as at i and provided with open notches 8 disposed in its edge for a purpose tov be hereinafter set forth. The door 5 consists of a plurality of horizontalr1y' disposed sections 9 provided with pairs of vertically spaced round lugs I on their opposite ends, each section, other than the bottom and top sections il and Qare also provided at its upper edge with lugs H having elongated apertures I2 therein to accommodate tongues I3 'formed on or otherwise secured to the lower edges thereof so as to lock the sections Atogether against bulging.
. The bottom section is provided with apertured lugs H' at its upper edge to receive the tongues on the section vabove and also with elongated lugs i4 at its lower edge for seating in apertures l i formed in the sill or bottom of the doorway. Secured to each section 9 is a flexible element preferably in the form of a chain Il having its opposite ends secured to a substantially U-shaped bracket i8 suitably attached to the top of the freight-car adjacent the doorway, said chains being of such lengths as will permit the sections to beremoved from the doorway and allowed to hang against the side of the freight-car.
The top section is provided at its lower edge with tongues i3 adapted to be seated in the apertures of the lugs il on the section below and is adapted to be secured against unauthor` ized removal by bolts i9 disposed adjacent its opposite ends, said bolts pass through the top section and are threadedly engaged with lugs 2D securely embedded in a cross-beam C over the doorway. `The heads ofv the aforesaid bolts I9 are preferablyv of unusual 'size or conguration so as to 'require a special wrench or tool to turn them in order that an unauthorized individual will be prevented from gaining access to the freight-car with an ordinary wrench or tool.
In order to assemble the sections, the lugs Ill of each section are inserted through the notches 8 in the guide-rails 6 and interlocked by the tongues i3 and apertured lugs H thereon wherelli 2 upon the sections are locked against removal by the top section when bolted to the cross beam C.
With this invention fully set forth it is manifest that a strong and thief-proof door is provided and, through the instrumentality of the exible connections thereof to the freight-car, the sections cannot be removed or lost.
Having thus described my invention, what I claim and desire to protect by Letters Patent is:
The combination with a box type freight-car having doorways therein, guide-rails disposed on opposite sides of the doorway and having open notches in their free edges, a bottom door section, elongated lugs on the lower edge of the bottom section seated in apertures in the sill of the door- Way, a plurality of section, pairs of round lugs on the sides of the sections resting on the lower.
sections adapted to pass through the notches in the guide-rails and slidably lodge behind the same, apertured lugs on the upper edges of certain of the sections, tongues on the lower edges of certain of the sections and adapted to seat in the apertured lugs, threaded lugs secured to a portion of the freight-car adjacent the top of the doorway in close proximity to the sides thereof an elongated bracket secured to the top of the car inwardly of the door, a chain connected to one side of each section of the door with its opposite end connected to the bracket and, bolts, having special heads, passing through the uppermost section and threadedly engaging the threaded lugs.
WILLIAM JOSEPH LEWIS.
