WILLIAM THORNBURGII, oF DETROIT, MICHIGAN.
CAR-DOOR.
SPECIFICATION forming part of Letters Patent No. 727,029, dated May 5, 1903.
Application filed August 23, 1902. Serial No. 120,777. (No model.)
To a/ZZ whom it may concern:
Be it known that LWILLIAM THORNBURGII, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Iniprovement in Car-Doors, of which the following is a specification, reference being had to lhe accompanying drawings, which form a part of this specification.
My invention has for its object certain new and useful improvements in a car-door, the same having` special adaptation as a grain-car door, although I do not limit myself thereto, as my invent-ion is adapted to a variety of uses.
Myinvention consists of the construction, combination, and arrangement of. devices hereinafter described and claimed, and illustrated in the accompanying drawings, in whichp yFigure l is a view in front elevation, the door being in closed and fastened position. Fig. 2 is a vertical crosssection illustrating features of my invention. Fig. 3 is a horizontal section on the line 3 3, Fig. l. Fig. 4 is a horizontal section, somewhat enlarged, on the line 4 4, Fig. l.
In carrying out my invention as illus trated in the drawings, a indicates the cardoor embodied in my invention, and h the body of the car formed with a door-frame c. The car-door is shown hinged, as at d, to an auxiliary door e, the door abeing arranged to swing outward when unlocked. The door is provided at its marginal edges with wings f to close behind the adjacent door-frame when the door is in locked position. These wings are hinged to the lateral edges of the door, as indicated at c in any suitable manner. Each of the wings is provided with an arm h. A locking-barz'is hinged in any suit-V able manner at the lower edge to the door a, as indicated at j, eyebolts, for example, serving to jointedly connect the locking-bar with the door.
The extremities of the locking-bar when the parts'are in locking position engage over the ends of the arm h to hold the wings in locked position, a latch 7c of any suitable construction-as a sliding latch, for example, (shown in Fig. 1)-serving to hold the lockingbar in closed or locked position. The locking-bar is arranged to fall by gravity when the latch is released therefrom. It will be evident that when the latch is unloosed from the locking-bar and the locking-bar has fallen into open position the weight of the grain or other commodity in the car will press the door open, the wings swinging out of locked position on their hinges. When in closed position, the wings close against the inside of the door-frame, the door opening outward when the wings are unlocked.
The auxiliary door e is preferably supported in such a manner as to be folded up under the roof of the' car, as indicated in dotted lines in Fig. 2. To this end it may be supported upon rods or links Z, jointedlyconnected at one end, as at m, with the body of the car and at the lower end, as at n, with the auxiliary door e. As so supported the door a may be swung up against the outer face of the door e and both then be folded up under the roof of the car, as indicated in dotted lines, Fig. 2, and held in such folded position in any suitable manner, as by hooks p.
The door e is provided with fixed metal wings q to secure durability. Experience has shown that where the ends of the door e are extended to lap over the door-frame nails are often driven thereinto and that the door in consequence is often so damaged thereby as to necessitate renewal or repairs; but by making the wooden part of the door lit in between the adjacent portions of the door-frame to extend simply to the adjacent portions of the frame and providing the same with the Iixed metal wings q nails cannot be driven therethrough, and the door is made much more durable, The wings fand q extend the whole width of the respective'doors.
While I donot limit myself to any particular manner of hinging the wingsf, it may conveniently be accomplished by means of eyebolts 7^, engaging said wings.
I do not'limit myself to providing the door with swinging wings at both ends, inasmuch as the door might be provided with a swinging wing at one end only within the scope of my invention.
W'hat I claim as my invention is- 1. A car-door having in combination therewith a vertical wing hinged to one end of the door, a looking-bar hinged at its lower edge to `engage said wing and hold the wing in closed position, and means to look said bar in closed position.
2. A oar-door having in combination therewith wings hinged to the extremities of said door respectively and each provided with an arm, a looking-bar hinged at the lower edge thereof to said door to hold said wings in closed position, and means to look said bar in closed position.
3. A car-door having in combination vertical Wings hinged to the ends of said door, a locking-bar hinged at its lower edge to enga ge said wings and hold said wings in closed position, and means to lock said bar in closed position.
4. A eardoor having in combination vertical Wings hinged to the ends of said doorl each provided with an arm extending toward the vertical center of the door when the door is in looked position, a locking-bar hinged at its lower edge to engagesaid arms to hold said Wings in closed position, and means to lock said bar in closed position.
5. A oar-door having in combination wings hinged to the ends of said door each provided with an arm, a-looking-bar hinged at its lower edge to engage said arms to hold said Wings in closed position, and means to look said bar in closed position, said bar arranged to open by gravity when the looking means is disengaged therefrom.
In testimony whereof I have signed this speoiioation in the presence of two subscribing witnesses.
WILLIAM THORNBURGH.
