DETACHABLE DOOR FOR DUMPlNG-CARS.

SPECIFICATION forming part of Letters Patent No. 632,315, dated September 5, 1899.

Application filed June 8, 1899. -Serial No."7l9,749. (N0 model.)

To aZZ whom it may concern:

Be it known that I, CARL PAUL LUDWIG, a citizen of the United States, residing at Woodward, in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Detachable Doors for Dump-Oars; 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 invention relates to improvements in a detachable door for mine-cars in which a tipple or dumping device is used to unload or discharge the cars; and the objects of my improvements are, first, to provide a mine or dump car with a detachable door of a simple and cheap construction which can be readily removed from the car before dumping the same; second, to provide a dump-car with forked side irons to engage the head-bar of a detachable door, the forks adapted to replace the door when the'tipple is reversed; third,

to provide a detachable doorfor dump-cars, the door attached tothe car by forked side irons and a bottom pin adapting its removal from the car when dumping the same, and, fourth, to provide a tipple or dump with a device having two projecting arms adapted to engage the head-bar of a detachable car-door and retain the same while the car is dumping. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side view of a mine-car in the usual position of dumping, the dotted lines showing the car before dumping. Fig. 2 is a top View of the same beforedumping.

with the usual form of wheels 2 2, mounted on axles in the usual manner. fine myself to the form of car shown.

I donot con- My im- Fig.3' is an end view of the same showing the de-' proved detachable door can be operated on any desired form of car. The side irons 3 3' on the front end of the car extend some distance above the sides thereof. The heads of the side irons are provided with forks 4: 4:, the sides of the forks being form ed at an angle to increase the distance between the points thereof.

The car-door 5 is made in the usual manner and of any suitable material. Two stropirons 6 6, bent in the center to form a double strop, are secured to the door in the usual manner. The head-bar 7is inclosed in the bends 8 8, formed in the heads of .the stropirons 6 6. Two collars 9 9' are provided in the head-bar between the strops to prevent side motion of the head-bar therein. Two collars 1O 10 are formed on the ends of the head-bar to guide the same when entering the forked side irons. The strop-iron 11, secured on the lower end of the door, has a pin 12 formed on its lower end. The pin is adapted to enter a hole formed in the drawbar 13, the pin holding the lower' part of the door to place in the end of the car. Two posts 14 '14 are secured on opposite sides of the tipple-opening. The posts are connected by a head-beam 15. Suitable braces 16 16' are secured behind the posts. Two angleirons 17 17', are attached to the face of the head-beam 15, the angle-irons forming extending arms to engage the head-iron of the car-door, the extending arms adapted to support the door when the car is dumping. Oorrugations 18 18 are formed onthe upper side of the angle-irons to prevent the headbar of the door from sliding thereon.

In operation the car is brought to the tipple in the usual manner. \Vhen the car is run on the tipple, the arms of the angle-irons 17 17 extend under the. head-bar 7 of the detachable door. The carwhen dumped leaves the detachable door suspended on the ex tending arms of the angle-bars, and when the tipple is reversed the forks on the side bars engage the head-bar of the door and place the same in position in the car.

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

A mine or dump car having side irons 3, 3 with forked heads formed thereon, a detachable door havinga head-bar '7 adapted to engage the forked heads of the side irons, the collars 9, 9 and 10, 10for1ned 0n the head-bar, the plate-iron 11 having a pin formed on its 1 lower end to engage the draw-bar, and means IO to suspend the door when the car is dumping, substantially as and for the purpose described. In testimony whereof I affix my signature in presence of two Witnesses.
